Description
Technical Field
[0001] The utility model relates to the technical field of inflators, in particular to a two-way inflator with a pressure gauge. Background Art
[0002] An inflator refers to an air pump used to provide inflation gas, injecting or supplementing the air required for various tires and some balls.
[0003] In daily life, people often need to inflate some objects. Among them, inflating balls is a common object that requires inflation through an inflator. Ordinary inflators usually adopt a leather cup piston structure. By pushing and pulling the piston rod up and down by hand, the purpose of inflation is achieved. Since this inflator can only inflate under the pulling action and can only deflate under the pushing action, it has the disadvantages of not being labor-saving, having a complex structure, and being inconvenient to carry. At the same time, since the hose and the needle of the inflator are mostly detachably connected and are connected outside the inflator, the hose and the needle of the inflator are extremely likely to be damaged or lost during use. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a two-way inflator with a pressure gauge.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A lower piston is arranged at one end of the traction tube. An upper piston is arranged on the side wall of the traction tube. A storage tube is fixedly connected to one side of the housing. A hose penetrates through the storage tube. A needle is arranged at one end of the hose. A storage mechanism for storing the hose and the needle is arranged inside the storage tube. A pressure gauge is fixedly connected to the side wall of the storage tube.
[0007] Preferably, including a housing, characterized in that an inner cylinder is arranged inside the housing. A traction tube is arranged inside the inner cylinder.

[0019] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0020] Referring to Figures 1 - 3 , a two-way inflator with a pressure gauge, which includes a housing 1. An inner cylinder 2 is provided inside the housing 1. A traction tube 3 is provided inside the inner cylinder 2. A lower piston 4 is provided at one end of the traction tube 3. An upper piston 5 is provided on the side wall of the traction tube 3. Sealing rings 14 are provided on the side wall of the inner cylinder 2, one side of the lower piston 4, and one side of the upper piston 5.
[0021] One side of the housing 1 is fixedly connected with a storage tube 9. A plurality of communication ports are opened at one end of the storage tube 9. The two communication ports on both sides communicate with two placement tubes 10 respectively. An end cap 11 is matched with the communication port, and a hose 12 penetrates through one communication port on one side.
[0022] A hose 12 penetrates through the storage tube 9. A connection thread is provided at the end of the hose 12 away from the needle 13. The hose 12 is threadedly connected inside the connection tube 7. A needle 13 is provided at one end of the hose 12. A storage mechanism for storing the hose 12 and the needle 13 is provided inside the storage tube 9. The storage mechanism includes two symmetrically arranged placement tubes 10 fixedly connected inside the storage tube 9. An end cap 11 is provided at one end of the placement tube 10.
[0023] A pressure gauge 8 is fixedly connected to the side wall of the storage tube 9. A connection frame 6 is fixedly connected inside the storage tube 9. A connection tube 7 is fixedly connected to one side of the connection frame 6. The connection tube 7 communicates with the traction tube 3. The air inlet of the pressure gauge 8 communicates with the connection tube 7.
[0024] When the present utility model is used, as Figures 1 - 3When in use, under the sealing action of the sealing ring 14, the movement of the traction pipe 3 can drive the simultaneous movement of the upper piston 5 and the lower piston 4. During the movement process, it can drive the upper piston 5 and the lower piston 4 to simultaneously compress the air. And through the connecting frame 6 and the connecting pipe 7, the compressed air is introduced into the needle 13 through the hose 12 to inflate the ball. During this process, the synchronous movement of the upper piston 5 and the lower piston 4 can maintain the continuous compression of the air, that is, both the pulling and pushing processes of the inflator can complete the inflation process. During this process, the pressure gauge 8 connected to the connecting pipe 7 through the pipeline can monitor the air pressure in the ball through the connection between the hose 12 and the sphere, facilitating the monitoring and adjustment of the pressure of the gas required in the ball. When the inflator is in a non-use state, at this time, the hose 12 connected by threads is disengaged from the inside of the connecting pipe 7, and the hose 12 and the needle 13 are respectively placed in the two placement pipes 10 on both sides and protected by the end cover 11 to prevent the loss of the hose 12 and the needle 13. At the same time, it facilitates the storage process. At the same time, the hose 12 extends to the inner cylinder 2 through the storage pipe 9 and is connected, which can avoid the problems of easy loss and damage of the hose 12 and the needle 13 caused by external connections.
[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
