[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown in the figure, the present invention provides a pressure detection device for an air compressor, including an air compressor body 100, the air compressor body 100 including a tank 101 and a pressure detector 102, the pressure detector 102 being disposed on the outside of the tank 101 via a detection component 103;

[0025] The detection assembly 103 includes a detection rod 103 disposed on the rear side of the pressure detector 102. The rear side of the detection rod 103 extends into the interior of the tank 101. A sealing sleeve 103 is disposed on the surface of the detection rod 103. The sealing sleeve 103 is used to seal the detection rod 103 and the tank 101.

[0026] A fixing ring 104 is fitted on the surface of the detection rod 103. A fixing block 105 is provided on the outside of the fixing ring 104. The rear side of the fixing block 105 is fixedly connected to the outside of the tank body 101. A plug-in component 106 is provided on the surface of the fixing ring 104. A pulling component 107 and a positioning component 108 are respectively provided inside the fixing block 105.

[0027] refer to Figures 1-3 The plug-in assembly 106 includes a plug-in rod 106 fixedly connected to the surface of the fixing ring 104. The outer side of the plug-in rod 106 contacts the surface of the plug-in groove 106, which is located inside the fixing block 105.

[0028] The above solution is adopted: the design of the plug-in component 106 enables a stable connection between the fixing ring 104 and the fixing block 105, preventing loosening or detachment due to vibration or external force. The cooperation between the plug-in rod 106 and the plug-in slot 106 makes the connection process simpler and faster, improving installation efficiency.

[0029] refer to Figure 3 , 4 The pulling assembly 107 includes pulling holes 107 on both sides of the fixed block 105. A pulling rod 107 is slidably connected to the surface of the pulling hole 107. Vertical rods 107 pass through the upper and lower sides of the pulling rod 107. The upper and lower sides of the vertical rod 107 are fixedly connected to the inner wall of the fixed block 105. A first spring 107 is sleeved on the surface of the vertical rod 107. The upper and lower sides of the first spring 107 are fixedly connected to the top of the pulling rod 107 and the inner wall of the fixed block 105, respectively.

[0030] The above solution allows users to easily move or adjust the fixed ring 104 by pulling the rod 107, improving operational flexibility. The first spring 107 acts as a buffer, reducing the impact on the fixed block 105 and connecting parts during the pulling process.

[0031] refer to Figure 3 , 4 The positioning component 108 includes a positioning rod 108 disposed inside the fixing block 105. The left side of the positioning rod 108 extends through to the left side of the fixing block 105. A crossbar 108 is disposed on the right side of the positioning rod 108.

The left and right sides of the second spring 108 are fixedly connected to the right side of the positioning rod 108 and the inner wall of the fixing block 105, respectively.

[0032] By adopting the above solution, the positioning component 108 ensures the accurate position of the fixing ring 104 in the fixing block 105, preventing detection errors caused by positional deviation. The cooperation between the crossbar 108 and the second spring 108 enables the positioning rod 108 to be stably held in the predetermined position, thereby improving the stability of the device.

[0033] refer to Figure 3 , 4 A connecting rod 201 is fixedly connected to the left side of the pulling rod 107. Connecting holes 202 are provided on both the front and rear sides of the connecting rod 201. A connecting post 203 is provided inside the connecting hole 202. The rear side of the connecting post 203 is fixedly connected to the front side of the positioning rod 108.

[0034] The above solution is adopted: through the design of connecting rod 201 and connecting column 203, a linkage relationship is formed between pulling rod 107 and positioning rod 108. When pulling rod 107 moves, it can drive positioning rod 108 to perform corresponding actions. This linkage design allows users to control pulling rod 107 and positioning rod 108 simultaneously with a simple operation, improving the convenience of operation.

[0035] refer to Figure 3 , 4 A travel groove 204 is provided on the right side of the positioning rod 108, and the inner side of the travel groove 204 is in contact with the surface of the crossbar 108.

[0036] The above solution is adopted: the design of the stroke groove 204 limits the range of movement of the positioning rod 108, preventing damage or failure caused by excessive movement. The cooperation between the stroke groove 204 and the crossbar 108 makes the overall structure more compact, which is conducive to saving space and improving the integration of the device.

[0037] refer to Figure 3 , 4 The fixing ring 104 has positioning grooves 205 on both the left and right sides. The opposite side of the positioning grooves 205 extends into the interior of the fixing block 105. The inner side of the positioning grooves 205 contacts the outer side of the positioning rod 108.

[0038] By adopting the above solution, the stability of the positioning rod 108 in the fixed block 105 is further enhanced by the design of the positioning groove 205, and the positional displacement caused by external force is prevented.

[0039] The working principle of this utility model:

[0040] The pressure detector 102 is connected to the tank 101 of the air compressor via the detection assembly 103. The detection rod 103 passes through the tank 101 and extends into the interior to sense the gas pressure inside the tank 101. The sealing sleeve 103 on the surface of the detection rod 103 ensures the sealing between the tank 101 and the detection rod 103 to prevent gas leakage.

[0041] The fixing ring 104 and the fixing block 105 work together through the plug-in assembly 106, the pulling assembly 107 and the positioning assembly 108 to firmly fix the detection rod 103 to the outside of the tank body 101. The plug-in rod 106 cooperates with the plug-in slot 106 to achieve quick connection. The pulling rod 107 and the first spring 107 provide a buffer function. The positioning rod 108 and the second spring 108 ensure the accurate positioning and automatic locking of the detection rod 103.

[0042] When the pressure detector 102 needs to be replaced or disassembled for maintenance, the worker can adjust the pull rod 107 upwards to move the connecting rod 201. As the connecting rod 201 moves, the connecting hole 202 presses against the outside of the connecting column 203, causing the connecting column 203 to move along the stroke of the connecting hole 202. This, in turn, moves the positioning rod 108. When the positioning rod 108 moves, it will disengage from the inside of the positioning groove 205. After the fixing ring 104 is released, the pressure detector 102 can be disassembled and replaced.

[0043] In summary, this pressure detection device for air compressors solves the problem that existing pressure detectors are generally installed by rotating them using threads, which is usually troublesome and reduces work efficiency when pressure detectors need to be replaced or disassembled.
