Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A water pressure gauge pressure calibration device comprises an operating panel 1, a clamping mechanism 2 is arranged on the top of the operating panel 1, a test assembly 3 is arranged on the top of the operating panel 1, and a sealing assembly 4 is arranged on one side of the test assembly 3;

[0031] The clamping mechanism 2 includes a fixed column 201, a fixed frame 202, a threaded column 203, a clamping block 204, a spring 205 and a clamping plate 206. The fixed column 201 is fixedly connected to the top of the operating panel 1, the fixed frame 202 is fixedly connected to the top of the fixed column 201, and multiple threaded columns 203 are all threadedly connected to the inside of the fixed frame 202.

[0032] Specifically, Figure 2 As shown, the test component 3 includes a fixed block 301, a T-shaped pipe 302, a first water tank 303, a two-way water pump 304 and a second water tank 305. The fixed block 301 is fixedly connected to the top of the operating panel 1, the T-shaped pipe 302 is fixedly connected to the top of the fixed block 301, the first water tank 303 is fixedly connected to one side of the T-shaped pipe 302, the two-way water pump 304 is arranged on the other side of the T-shaped pipe 302, and the second water tank 305 is arranged on the other side of the two-way water pump 304.

[0033] Specifically, Figure 4 As shown, a support column 5 is fixedly connected to the bottom of the operating panel 1 , and a support leg 6 is fixedly connected to the bottom of the support column 5 .

[0034] Specifically, Figure 2 As shown, one side of the fixed frame 202 is fixedly connected to the telescopic rod 7 , and the other side of the telescopic rod 7 is fixedly connected to the clamping block 204 .

[0035] Specifically, Figure 3 As shown, a drainage pipe 8 is fixedly connected to one side of the second water tank 305 , and a rotating cap 9 is threadedly connected to the outer wall of the drainage pipe 8 .

[0036] Specifically, Figure 4 As shown, one side of the plurality of support columns 5 is respectively fixedly connected with a reinforcement block 10 .

[0037] Specifically, Figure 3 As shown, one side of the clamping plate 206 is fixedly connected to the inclined plate 11 .

[0038] When in use, the user can fill the first water tank 303 with water, fix the bottom of the water pressure gauge on the top of the T-shaped pipe 302, and then rotate the threaded column 203 to allow the clamping block 204 to slowly approach the water pressure gauge housing. When the water pressure gauge enters the clamping block 204, it will squeeze the inclined plate 11 and the clamping plate 206 to cause the spring 205 to contract, clamping the water pressure gauge to prevent it from shaking during testing and calibration, and start the two-way water pump 304 to pump out the water in the first water tank 303 and pass it through the T-shaped pipe 302 to let the water The pressure gauge can perform pressure testing, and the pumped water will enter the second water tank 305. Reverse starting of the two-way water pump 304 can transfer the water in the second water tank 305 to the first water tank 303 again. Multiple tests can improve the accuracy of the test results. The support column 5, support leg 6 and reinforcement block 10 are used together to provide support for the operating panel 1. The telescopic rod 7 can increase the stability of the clamping block 204 when moving.

[0040] When in use, after the water pressure gauge is fixed on the top of the T-shaped pipe 302, its outer wall will be wrapped by the sealing ring 402. When water flows in the T-shaped pipe 302, the sealing ring 402 and the sealing ring 403 are used in conjunction to prevent water overflow and increase the sealing between the bottom of the water pressure gauge and the T-shaped pipe 302.

[0041] By adopting the above technical solution, a problem is solved in which an existing water pressure gauge pressure calibration device lacks the function of fixing the water pressure gauge when in use. When the water pressure gauge is used for pressure testing, the water pressure gauge is usually shaken by the impact of the water flow, thereby affecting the accuracy of the measurement data.

[0042] Working principle: When the present application is in use, the user can inject water into the first water tank 303, fix the bottom of the water pressure gauge on the top of the T-shaped pipe 302, and use the sealing ring 402 and the sealing ring 403 together to prevent water from overflowing and increase the sealing between the bottom of the water pressure gauge and the T-shaped pipe 302. Then, the threaded column 203 is rotated to allow the clamping block 204 to slowly approach the water pressure gauge. When the water pressure gauge enters the clamping block 204, the inclined plate 11 and the clamping plate 206 are squeezed to cause the spring 205 to contract, thereby clamping the water pressure gauge to prevent it from overflowing during operation. If shaking occurs during the test calibration, start the two-way water pump 304 to pump out the water in the first water tank 303 and pass it through the T-pipe 302, so that the water pressure gauge can perform a pressure test. The pumped water will enter the second water tank 305. Start the two-way water pump 304 in the reverse direction to transfer the water in the second water tank 305 to the first water tank 303 again. Multiple tests can improve the accuracy of the test results. The support column 5, support leg 6 and reinforcement block 10 are used together to provide support for the operating panel 1, and the telescopic rod 7 can increase the stability of the clamping block 204 when it moves.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
