The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figures 1 to 5 , is the first embodiment of the utility model, which provides a high and low pressure water and gas test bench for compression-type pipe fittings, including:

[0027] The detection assembly 100 includes a workbench 101, an air compressor 102 is provided above the workbench 101, a protective door 103 is hingedly connected to one side of the outer surface of the air compressor 102, and a water tank 104 is fixedly installed on one side of the workbench 101;

[0028] The water tank 104 is filled with water to perform a leak test.

[0029] The locking assembly 200 includes a fixing box 201 fixedly connected to one side surface of the protective door 103, a fixing block 202 fixedly connected to one side of the outer surface of the air compressor 102, and a disc 203 fixedly connected to the inner surface of the fixing box 201 via a bearing.

[0030] A groove of the same size is formed on one side surface of the fixing box 201 and the fixing block 202 .

[0031] Specifically, the detection assembly 100 further includes a low pressure gauge 105 and a high pressure gauge 106 disposed on one side surface of the workbench 101 . A low pressure regulator 107 and a high pressure regulator 108 are also disposed on one side surface of the workbench 101 .

[0032] The low pressure gauge 105 and the high pressure gauge 106 are both used to display the air pressure, and the low pressure regulator 107 and the high pressure regulator 108 are both used to adjust the air pressure.

[0033] Furthermore, the detection component 100 also includes a connecting hose 109 , and an air pressure tube 110 is adapted to be installed on the bottom of the outer surface of the workbench 101 . A first air pressure valve 111 is provided on the outer surface of the air pressure tube 110 .

[0034] The first air pressure valve 111 is used for performing an air pressure test.

[0035] Preferably, the detection component 100 further includes a second air pressure valve 112 provided at one end of the connecting hose 109 , and a water pipe 113 is provided in the inner cavity of the water tank 104 , and a faucet 114 is adapted to be installed on the surface of the water pipe 113 .

[0036] The second air pressure valve 112 is used for performing a water pressure test.

[0037] It should be noted that the detection assembly 100 further includes a high-pressure connection port 115 adapted to be installed at the bottom of the outer surface of the air compressor 102 , and a low-pressure connection port 116 adapted to be installed at the bottom of the outer surface of the air compressor 102 .

[0038] The high-pressure connection port 115 and the low-pressure connection port 116 are both used to install the connecting hose 109 .

[0039] When in use, fill the water tank 104 with water to perform a leak test, prepare to install the connecting hose 109, connect the air pressure tube 110 to the corresponding inlet according to the range and accuracy of the test, and place the second air pressure valve 112 of the component into the water of the water tank to a depth of no more than 5 cm. Open the first air pressure valve 111, adjust the pressure regulator appropriately, and gradually increase the air pressure to the set value according to the previous connection. When the pressure is set, open the air pressure valve and maintain the pressure for a period of time. When the test is completed, use a suitable pressure regulator to gradually release the air pressure. After the pressure relief is completed, remove all components and close all valves.

[0040] In summary, through the setting of the detection component 100, the water pressure detection device and the air pressure detection device can be integrated into one, which can meet the needs of water pressure and air pressure testing at the same time, thereby improving the testing efficiency and flexibility. There is no need to switch between different devices, which greatly improves the testing efficiency.

[0041] Example 2

[0042] Reference Figure 2 and Figure 4 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides the structure and function of a locking assembly 200.

[0043] Specifically, the locking assembly 200 also includes a worm 204 fixedly connected to the other end of the disc 203, and the other end of the worm 204 is fixedly connected to the surface of one side of the inner wall of the fixed box 201 through a bearing. The upper and lower surfaces of the inner wall of the fixed box 201 are fixedly connected to the same rotary column 205 through bearings, and the surface of the rotary column 205 is fixedly connected to a worm gear 206.

[0044] The threads of the worm 204 mesh with the teeth of the worm wheel 206 .

[0045] Furthermore, the locking assembly 200 also includes a gear 207 fixedly connected to the surface of the rotating column 205. A support frame 208 is fixedly installed on the bottom surface of the inner wall of the fixed box 201, and a rack 209 is slidably connected to the inner surface of the support frame 208.

[0046] The rotating column 205 is used to support the worm wheel 206 and the gear 207 , and the supporting frame 208 is used to limit the rack 209 .

[0047] During use, the rotating disc 203 drives the worm 204 to rotate, and the worm 204 drives the worm wheel 206 to rotate synchronously. At the same time, the worm wheel 206 drives the gear 207 to rotate through the rotating column 205. The support frame 208 limits the rack 209, so that the rack 209 moves linearly through the rotation of the gear 207, so that the rack 207 is inserted into the groove opened on the surface of the fixed block 202, so as to facilitate maintenance personnel to inspect and repair the air compressor 102.

[0048] In summary, the provision of the locking assembly 200 enables maintenance personnel to quickly open the interior of the protective door 103 of the air compressor 102 and directly access the components that need maintenance, thereby shortening maintenance time and improving maintenance efficiency.
