For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a fire extinguisher pressure gauge testing device, comprising:

[0032] Test bench 1 is equipped with a testing mechanism. It should be noted that the testing mechanism allows for quick and easy replacement of the pressure gauges of the fire extinguishers to be tested, and multiple pressure gauges of fire extinguishers to be tested can be tested at the same time, effectively improving work efficiency.

[0033] The testing mechanism includes a support plate 2, a booster pump 3, a connecting pipe 4, a reference fire extinguisher pressure gauge 5, a hydraulic cylinder 6, a push plate 7, a connecting plate 8, a ring 9, a pressure gauge of the fire extinguisher to be tested, a rotating shaft 13, and an abutment plate 14.

[0034] The support plate 2 is fixedly installed on the top of the test bench 1, the booster pump 3 is fixedly installed on the support plate 2, the booster pump 3 is fixedly connected to the connecting pipe 4, and the reference fire extinguisher pressure gauge 5 is fixed on the connecting pipe 4. It should be noted that the reference fire extinguisher pressure gauge 5 provides a reference, and the pressure gauge of the fire extinguisher under test is tested by checking the result of the reference fire extinguisher pressure gauge 5.

[0035] Hydraulic cylinder 6 is fixedly installed on the top of test bench 1. The hydraulic rod of hydraulic cylinder 6 is fixedly connected to push plate 7. Connecting plate 8 is fixedly installed on push plate 7. Ring 9 is fixedly installed on connecting plate 8. The pressure gauge of the fire extinguisher to be tested abuts against ring 9. The pressure gauge of the fire extinguisher to be tested is clamped to connecting pipe 4. Rotary shaft 13 is rotatably installed on connecting plate 8. Rotary shaft 13 is fixedly connected to abutting plate 14. Abutting plate 14 is clamped to support plate 2.

[0036] Using the aforementioned testing mechanism, the pressure gauges of the fire extinguishers to be tested are placed sequentially on the ring 9. Then, the rotating shaft 13 is rotated so that the abutment plate 14 engages with the ring 9 to abut and limit the pressure gauges. Then, the hydraulic cylinder 6 is activated so that the vertical tube 11 on the pressure gauge is engaged with the connecting pipe 4, and the abutment plate 14 is engaged with the limiting groove 15. Then, the booster pump 3 is activated, using the reference fire extinguisher pressure gauge 5 as a reference. In this way, multiple fire extinguisher pressure gauges can be tested simultaneously. After the test is completed, the hydraulic cylinder 6 is activated so that the pressure gauges are moved upward. Then, the abutment plate 14 is rotated so that it separates from the pressure gauge. Finally, the pressure gauge is pulled upward to remove it. Multiple fire extinguisher pressure gauges can be tested at once, effectively improving work efficiency.

[0037] Specifically, the testing mechanism also includes a placement seat 16 and a pre-installed component. The placement seat 16 is fixedly installed on the support plate 2. The pre-installed component includes a thin rod 17 and a thick rod 18. The bottom of the thick rod 18 is fixedly connected to the thin rod 17, and the thin rod 17 is engaged with the placement seat 16.

[0038] Using the aforementioned testing mechanism, when the number of pressure gauges for the fire extinguishers to be tested is small, such as one, two, or three, the pressure gauges are placed on ring 9, and then a spare part is placed on the remaining ring 9. This can seal the insertion hole on the connecting pipe 4, making it easier to test a small number of pressure gauges for the fire extinguishers to be tested.

[0039] Specifically, the pressure gauge of the fire extinguisher under test includes a dial 10 and a vertical pipe 11. The dial 10 is fixedly connected to the vertical pipe 11. The bottom of the dial 10 abuts against the ring 9, and the top of the dial 10 contacts the abutment plate 14. Multiple insertion holes are provided on the connecting pipe 4, and sealing gaskets 12 are fixedly installed in the insertion holes. The pressure gauge of the fire extinguisher under test is in sealed contact with the sealing gaskets 12. It should be noted that this can ensure the sealing performance of the pressure gauge of the fire extinguisher under test after it is inserted into the connecting pipe 4.

[0040] Specifically, the push plate 7 has a square hole 20 on its side, which allows the push plate 7 to move within a small range in the vertical direction.

[0041] Specifically, the connecting pipe 4 is fixedly installed on the support plate 2, and a solenoid valve 19 is installed on the connecting pipe 4. It should be noted that after the test is completed, the solenoid valve 19 is opened to perform a pressure relief operation.

[0042] Specifically, a limiting groove 15 is provided on the top of the support plate 2, and the abutment plate 14 is engaged with the limiting groove 15. It should be noted that the abutment plate 14 can be limited to prevent the abutment plate 14 from rotating during the test.

[0043] Specifically, there are multiple pressure gauges for the fire extinguishers to be tested, and these multiple pressure gauges are set at equal intervals. It should be noted that multiple pressure gauges for the fire extinguishers to be tested can be tested at the same time, which effectively improves work efficiency.

[0044] Working principle:

[0045] S1: Place the pressure gauges of the fire extinguishers to be tested sequentially on the ring 9, then rotate the shaft 13 so that the abutment plate 14 and the ring 9 cooperate to abut and limit the pressure gauges of the fire extinguishers to be tested. Then start the hydraulic cylinder 6 so that the push plate 7, connecting plate 8, ring 9, shaft 13 and abutment plate 14 move downward synchronously. This can drive the multiple pressure gauges of the fire extinguishers to be tested after being limited to move downward, so that the vertical tube 11 on the pressure gauge of the fire extinguisher to be tested is inserted into the connecting tube 4, and the abutment plate 14 is inserted into the limiting groove 15. Then start the booster pump 3, using the reference fire extinguisher pressure gauge 5 as a reference, so that multiple pressure gauges of the fire extinguishers to be tested can be tested simultaneously.

[0046] S2: After the test is completed, open the solenoid valve 19 to release the pressure, start the hydraulic cylinder 6 to move the pressure gauge of the fire extinguisher under test upward, then rotate the abutment plate 14 to separate the abutment plate 14 from the pressure gauge of the fire extinguisher under test, and finally pull the pressure gauge of the fire extinguisher under test upward to remove it.

[0047] S3: Continue testing the pressure gauges of the next group of fire extinguishers to be tested. This allows for quick and easy replacement of the pressure gauges and enables testing of multiple pressure gauges at once, effectively improving work efficiency.

[0048] The fire extinguisher pressure gauge testing device provided by this utility model has been described in detail above. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
