[0030] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] Example 1

[0032] like Figures 1 to 5 As shown, a detection device that can be used for instruments includes a pressure chamber 1, an air pump 2 is fixedly connected to one side of the pressure chamber 1, and a plurality of pressure instrument interfaces 3 are fixedly connected to the outside of the pressure chamber 1.

[0033] like Figures 1 to 2 As shown, the central pressure instrument interface 3 is threadedly connected to a standard pressure instrument 4, and the pressure instrument interfaces 3 on both sides are threadedly connected to high-pressure hoses 5. The interface specifications of the high-pressure hoses 5 are adapted to the interface specifications of the pressure instrument to be tested. By providing multiple pressure instrument interfaces 3 on both sides of the pressure chamber 1, the pressure instrument testing device can be equipped with multiple pressure instruments at the same time. The pressure conditions of multiple pressure instruments are compared at the same time, which increases the comparison parameters of the instrument testing, improves the testing accuracy, and avoids the situation where the error of the standard pressure instrument 4 affects the test results. In addition, by connecting multiple pressure instruments at the same time, the testing work of multiple pressure instruments can be completed at one time, thereby improving the testing efficiency of the pressure instruments.

[0034] A high-pressure hose 5 is provided at the end of the pressure instrument interface 3 on both sides. After the pressure instrument is docked with the high-pressure hose 5, the high-pressure hose 5 can be bent to adjust the position of the pressure instrument, so that multiple pressure instruments and the pressure instrument interface 3 can be arranged side by side to prevent pressure parameter comparison, making parameter comparison during the detection process more convenient and efficient. In addition, the pressure instruments in some factories are in a semi-fixed state. Even if they are disassembled and docked with the detection device, the pressure instruments cannot be moved significantly. The high-pressure hose 5 is provided between the pressure instrument and the detection device, which can make the docking of the semi-fixed pressure instrument more convenient and avoid the situation where the pressure instrument is inconvenient to move and the detection device is inconvenient to operate.

[0035] The length of the high-pressure hose 5 is greater than the diameter of the pressure chamber 1, which is sufficient for the user to bend the high-pressure hose 5 to adjust the position of the detection equipment and the pressure instrument as needed;

[0036] The pressure load of the high-pressure hose is greater than the maximum pressure output by the air pump 2, so that the high-pressure hose 5 can withstand the various air pressure intensities generated by the air pump 2 during the pressure detection process, avoiding safety accidents caused by the rupture of the high-pressure hose 5 due to excessive air pressure.

[0037] As shown in Figures 1 to 5 The end of the high-pressure resistant hose 5 is provided with a clamping groove, and the two sides of the pressure chamber 1 are fixedly connected with clamping portions 6. The shape of the clamping portion 6 is matched with the shape of the clamping groove of the end of the high-pressure resistant hose 5. The pressure gauges after being clamped by the clamping portion 6 are arranged side by side adjacent to the standard pressure gauge 4. By arranging the clamping portion 6 on the two sides of the pressure chamber 1, the end of the high-pressure resistant hose 5 can be clamped and fixed, so that the detected pressure gauges can be fixed side by side on the two sides of the standard pressure gauge 4, which facilitates the comparison and reference of the pressure data of the two, and the process of comparing the pressure parameters does not need to hold multiple pressure gauges, so that the comparison of the pressure parameters of the detection device is more convenient.

[0038] Embodiment 2

[0039] As shown in Figures 2 to 3 The gas outlet of the air pump 2 is in communication with the gas inlet of the pressure chamber 1, and the end of the gas outlet of the air pump 2 is provided with a buffer device. By arranging the air pump 2 on one side of the pressure chamber 1, the air pump 2 can inflate the pressure chamber 1, increase the air pressure in the pressure chamber 1, facilitate the pressure gauge to measure and compare the pressure in the pressure chamber 1, and thus judge whether the detected pressure gauge has a fault.

[0040] The buffer device arranged at the gas outlet of the air pump 2 can buffer the force generated by the airflow, so as to avoid the situation that the pressure gauge directly opposite to the gas outlet of the air pump is subjected to greater pressure due to the large airflow, which affects the detection result. The pressure of each pressure gauge interface in the pressure chamber 1 is consistent, so as to take the measured pressure as a comparison basis.

[0041] Embodiment 3

[0042] As shown in Figures 2 to 3 The top side of the pressure chamber 1 is provided with a circular slot, and the inner side of the circular slot is fixedly connected with a sealing rubber sheet 7. The sealing rubber sheet 7 is made of high-pressure resistant rubber, and the air pressure that can be borne by the sealing rubber sheet 7 is greater than the maximum output pressure of the air pump 2. By arranging the sealing rubber sheet 7 on the top side of the pressure chamber 1, the approximate pressure in the pressure chamber 1 can be judged according to the bulging of the sealing rubber sheet 7. Without looking at the standard pressure gauge 4, the air pump 2 can be controlled to adjust the pressure in the pressure chamber 1 to a proper value, so as to facilitate the measurement and comparison of the pressure gauges and the standard pressure gauge, and complete the detection of the pressure gauges.

[0043] Embodiment 4

[0044] As shown in Figure 1As shown, the pressure chamber 1 is crescent-shaped, and the shape of the air pump 2 is adapted to the crescent notch of the pressure chamber 1. By setting the pressure chamber 1 and the air pump 2 to complementary crescent shapes and circles, the fit between the two is closer, and the overall shape is more reasonable, which is convenient for the operator to carry and operate. Compared with the square instrument detection device, the circular instrument detection device is safer and can avoid the operator from bumping into the edges and corners of the instrument detection device and causing harm to himself during operation.

[0045] like Figure 5 As shown, a handle 8 is fixedly connected to the rear side of the air pump 2, and the material of the handle 8 is hard silicone. By arranging the handle 8 on the rear side of the air pump 2, when testing the air pressure instrument, the handle 8 can be held in one hand to complete the lifting of the detection device, which is convenient for freeing up the other hand for assembly, adjusting the air pressure, performing testing and other operations, making the detection device more convenient to operate and carry, and the handle 8 made of hard silicone has high hardness and corrosion resistance, and has a long service life.

[0046] like Figures 1 to 2 As shown, the ends of the high-pressure hose 5 are threadedly connected with sealing pistons 9. By arranging the sealing pistons 9 at the ends of the high-pressure hose 5, when there is no need to detect a large number of pressure instruments, the sealing pistons 9 can be used to seal the idle high-pressure hoses 5, thereby avoiding the situation where the open high-pressure hoses 5 are not sealed and the pressure inside the pressure chamber 1 is relieved.

[0047] The working principle of this utility model is as follows:

[0048] S1. Install the standard pressure instrument 4 on the middle pressure instrument interface 3;

[0049] S2. Remove the pressure instrument to be tested from the original equipment and install it on the high-pressure hose 5 of the pressure chamber 1;

[0050] S3. When the pressure instrument is in a semi-fixed state, bend the high-pressure hose 5 to make the connection between the pressure instrument and the detection device smoother and more convenient. When the pressure instrument is completely disassembled, adjust the state of the high-pressure hose 5 so that the pressure instrument and the standard pressure instrument are side by side for convenient comparative testing, and fix the end of the high-pressure hose 5 on the clamping part 6 to complete the fixation;

[0051] S4. Start the air pump 2 to pressurize the interior of the pressure chamber 1, raise the air pressure in the pressure chamber 1 to the required detection height, compare the parameters displayed on the pressure instrument, and determine whether the pressure instrument has a fault based on the comparison result.
