Description

Easy to assemble pump

This creation mainly reveals a kind of pump, especially an easy-to-assemble pump.

A general portable pump, such as the pump disclosed in the Republic of China Announcement No. 410912, roughly includes a pump body, a one-way valve seat, a piston, and a tube body. The outer edge of one end of the pump body is provided with an external threaded part to screw the pivoting seat, and the bearing part of the pivoting seat can accommodate the end of the inner nozzle head. One end of the piston is provided with a threaded part to be screwed in the screw hole of the pipe body.

When assembling the above-mentioned pump, the piston must be screwed and combined with the pipe body, and the one-way valve seat must be placed on the pump body, and then the pivotal seat and the external thread part of the pump body must be screwed and combined. However, this type of assembly process is too complicated, resulting in higher production costs. Therefore, how to overcome the various problems of the above-mentioned existing pumps has become an urgent problem to be solved at present.

This creation provides an easy-to-assemble pump, which can simplify the assembly process of the pump and shorten the assembly time, so as to reduce the production cost.

The easy-to-assemble pump provided by this creation includes a cylinder, a piston assembly, a valve seat and a nozzle head. The piston assembly includes an integrally formed piston part and a rod part, the piston part is axially movably arranged in the cylinder, and the rod part extends out of the cylinder. The valve seat is contained in the cylinder. The gas nozzle head is connected to one end of the cylinder.

In an embodiment of the present creation, the cylinder has a first perforation penetrating the circumferential surface of the cylinder. The valve seat has a second perforation corresponding to the first perforation. The gas nozzle head has a third perforation corresponding to the second perforation. The first pin penetrates through the first through hole, the second through hole and the third through hole.

In an embodiment of the present creation, the first pin has a through hole, and the through hole communicates with the cylinder and the gas nozzle head.

In an embodiment of this creation, it also includes a grip and a second pin. The end of the cylinder opposite to the valve seat is provided with an end cover. The rod has a pivot end extending out of the end cover and a first pivot hole arranged at the pivot end. The handle has a second pivot hole corresponding to the first pivot hole. The second pin passes through the first pivot hole and the second pivot hole, so that the handle is pivotally connected to the pivot end.

In an embodiment of the present invention, the end cover is screwed to the end of the cylinder opposite to the valve seat.

Based on the above, the easy-to-assemble pump provided by the above-mentioned embodiment of the present creation has an integrally formed piston part, a rod part, and a first pin through the first perforation of the cylinder, the second perforation of the valve seat, and the air pump. The third perforation of the nozzle head effectively simplifies the assembly process of the pump and shortens the assembly time, thereby reducing the production cost.

In order to make the above-mentioned features and advantages of this creation more obvious and understandable, the following specific examples are given in conjunction with the accompanying drawings to describe in detail as follows.

Regarding the techniques, methods and effects used in this creation, a preferred embodiment is given in conjunction with the detailed descriptions below, which are for illustrative purposes only, and are not limited by this structure in the patent application. Figure 1 is a schematic diagram of the appearance of an easy-to-assemble pump according to an embodiment of the invention. Fig. 2 and Fig. 3 are respectively schematic cross-sectional views of the easy-to-assemble pump shown in Fig. 1. 1 to 3, the easy-to-assemble pump of this embodiment includes a cylinder 10, a piston assembly 20, a valve seat 30, a nozzle head 40, a first pin 50, a grip 60, and a first Two pin 70.

The cylinder 10 has a first through hole 11 penetrating the circumferential surface of the cylinder 10 and an end cover 12. The end cover 12 is screwed to the end of the cylinder 10 opposite to the valve seat 30. The piston assembly 20 includes a piston part 21 and a rod part 22 which are integrally formed. The piston part 21 is axially movably arranged in the cylinder 10. The rod 22 protrudes out of the cylinder 10, and the rod 22 has a pivot end 221 protruding out of the end cover 12 and a first pivot hole 222 disposed at the pivot end 221. The valve seat 30 is accommodated in the cylinder 10 and has a second through hole 31 corresponding to the first through hole 11. The nozzle head 40 is connected to one end of the cylinder 10 and has a third hole 41 corresponding to the second hole 31. The first pin 50 passes through the first through hole 11, the second through hole 31, and the third through hole 41. The first pin 50 has a through hole 51 that connects the cylinder 10 and the nozzle head 40 so that the cylinder 10 The air compressed by the piston part 21 can pass through the valve seat 30 and the air nozzle head 40 to enter the inflatable object connected to the air nozzle head 40 (not shown in the figure). The handle 60 has a second pivot hole 61 corresponding to the first pivot hole 222. The second pin 70 penetrates through the first pivot hole 222 and the second pivot hole 61, so that the handle 60 is pivotally connected to the pivot end 221 of the rod 22.

In summary, the easy-to-assemble pump of this embodiment has the piston part 21 and the rod part 22 integrally formed, so that the assembly of the piston assembly 20 can be avoided during the process of assembling the pump. The piston and the tube body are screwed together to simplify the assembly process of the pump. In addition, when assembling the easy-to-assemble pump of this creation, it is only necessary to install the valve seat 30 and the nozzle head 40 on one end of the cylinder 10 respectively, and use the first pin 50 to penetrate the first through hole 11 and the valve seat 30 of the cylinder 10 The second perforation 31 of the gas nozzle head 40 and the third perforation 41 of the gas nozzle head 40 can quickly complete the assembly, which greatly shortens the assembly time and reduces the production cost.

However, the above are only examples of this creation, and should not be used to limit the scope of implementation of this creation, that is, all simple equivalent changes and modifications made in accordance with the scope of patent applications and new descriptions of this creation are still It is within the scope of this creation patent. In addition, any embodiment of this creation or the scope of the patent application does not have to achieve all the purposes or advantages or features disclosed in the creation. In addition, the abstract part and title are only used to assist in searching for patent documents, not to limit the scope of rights of this creation. In addition, the terms "first" and "second" mentioned in this specification or the scope of the patent application are only used to name the element (element) or to distinguish different embodiments or ranges, and are not used to limit the number of elements.
