Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to an electric pressure vacuum alternating testing machine. Background Art

[0002] The pressure gauge fatigue testing machine is a kind of testing equipment used to perform pressure tests and fatigue alternating tests on instruments such as high-precision pressure gauges and stainless steel pressure gauges. This test is required when testing the service life of the pressure gauge to ensure a comprehensive quality assessment of the pressure gauge. The existing patent (Announcement No.: CN204422139U) discloses a pressure gauge fatigue testing machine. This utility model realizes efficient fatigue testing of pressure instruments by setting up air pressure pipelines, water pressure pipelines and control circuits, and utilizing circuit control. It has a high degree of automation and achieves higher work efficiency. However, in actual applications, since the connection end of the pressure gauge joint is in an open state for a long time, dust is easily introduced when the pressure gauge is not connected. Testing in this case will lead to inaccurate test results, which is not conducive to practical application. To this end, we propose an electric pressure vacuum alternating testing machine. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an electric pressure-vacuum alternating testing machine.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] An electric pressure-vacuum alternating testing machine is designed, comprising a fatigue testing machine body with a control area provided on one side. The fatigue testing machine body is connected to an air source device and a water source device respectively. A storage groove is provided on the top of the fatigue testing machine body. A medium pipe is provided in the storage groove. A joint pipe is provided on the medium pipe. A valve is installed on the joint pipe. A cover plate hinged to the fatigue testing machine body is provided above the joint pipe. A handle is fixed on the top of the cover plate. A sealing plug is inserted into the joint pipe.

[0006] In the above solution, movable wheels are installed at the four corners of the bottom of the fatigue testing machine body, and a push handle is installed at one end of the fatigue testing machine body.

[0007] In the above solution, the number of the medium pipes is at least two.

[0008] In the above solution, the cover plates are symmetrically arranged at both ends of the fatigue testing machine body, and the inner walls of the cover plates are covered with a waterproof layer.

[0009] In the above solution, the cover plate is fixed with an assembly plate, the assembly plate and the fatigue testing machine body are fixed with connecting seats, a telescopic rod is provided between the connecting seats, and both ends of the telescopic rod are connected to the connecting seats through a damping shaft.

[0010] In the above solution, the assembly plate is a magnetic assembly plate, and adjacent assembly plates have opposite magnetism.

[0011] In the above solution, the telescopic rod is set as an electric telescopic rod.

[0012] The advantages and beneficial effects of the present invention are: by arranging a storage groove, a cover plate, a medium pipe, a joint pipe and a valve, and by placing the medium pipe and the joint pipe in the storage groove, when testing is required, it is only necessary to lift up the cover plate to expose the storage groove, thereby exposing the medium pipe and the joint pipe for connecting the pressure gauge. Compared with the prior art, when testing is not required, the cover plate can be used to cover the storage groove to prevent dust from accumulating in the storage groove and the joint pipe, thereby achieving a dust-proof effect, effectively avoiding affecting the detection accuracy, ensuring the accuracy of the device detection, and improving practicality. By arranging an assembly plate and a telescopic rod, and by setting the telescopic rod as an electric telescopic rod, the angle between the cover plate and the top of the fatigue testing machine body can be adjusted by controlling the length of the telescopic rod, thereby changing the state of the cover plate, so that the cover plate can be freely switched between the switch state, thereby improving the degree of automation, and achieving a dust-proof effect while being more convenient to use.

DETAILED DESCRIPTION

[0017] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] See also Figure 1-2The utility model provides a technical solution: an electric pressure vacuum alternating tester, comprising a fatigue tester body 1 with a control area 3 on one side, a control box provided in the fatigue tester body 1, a control circuit provided in the control box, and the fatigue tester body 1 connected to an air source device and a water source device respectively;

[0019] Specifically, the fatigue testing machine body 1 is provided with an air pressure pipeline, which is composed of an air intake source, a pressure regulating valve, a low-pressure pressure gauge, a solenoid valve, and a supercharger in series. The air pressure pipeline is connected to the air source equipment. The water pressure pipeline is composed of a high-pressure water pump, a one-way valve, a water inlet valve, and a water discharge valve in series. The water pressure pipeline is connected to the water source equipment. By controlling the cyclic action of the pneumatic components to increase and release the pressure, the pressure gauge that needs to be subjected to fatigue testing is driven. The pipeline between the water inlet valve and the water discharge valve is connected to the pressure gauge connector, the high-pressure pressure gauge, and the supercharger; the control circuit is connected to the solenoid valve, and the fatigue test is automatically completed through the control circuit. The use of a high-performance high-pressure water pump and stainless steel valves can ensure long-term and reliable operation of the equipment. The control circuit has been disclosed in the utility model with the announcement number CN204422139U.

[0020] A receiving groove 4 is provided on the top of the fatigue testing machine body 1, and a medium tube 5 is provided in the receiving groove 4;

[0021] Furthermore, the medium pipe 5 is provided with at least two;

[0022] A joint pipe 6 is provided on the medium pipe 5, and a valve 7 is installed on the joint pipe 6. A cover plate 10 hinged to the fatigue testing machine body 1 is provided above the joint pipe 6. A handle 12 is fixed on the top of the cover plate 10. A sealing plug 8 is inserted into the joint pipe 6.

[0023] Specifically, by providing a storage groove 4, a cover plate 10, a medium pipe 5, a joint pipe 6 and a valve 7, and by placing the medium pipe 5 and the joint pipe 6 in the storage groove 4, when testing is required, it is only necessary to lift up the cover plate 10 to expose the storage groove 4, thereby exposing the medium pipe 5 and the joint pipe 6 for connecting the pressure instrument. Compared with the existing technology, when testing is not required, the cover plate 10 can be used to cover the storage groove 4 to prevent dust from accumulating in the storage groove 4 and the joint pipe 6, thereby achieving a dust-proof effect, effectively avoiding affecting the detection accuracy, ensuring the accuracy of the device detection, and improving practicality.

[0024] Furthermore, the fatigue testing machine body 1 is provided with moving wheels 2 at the four corners of the bottom, and a push handle 9 is provided at one end of the fatigue testing machine body 1;

[0025] Specifically, the moving wheel 2 is a universal wheel with a braking function, which is not only convenient for movement, but also allows the fatigue testing machine body 1 to stay at a specific position. Together with the push handle 9, it is convenient to control the moving direction of the fatigue testing machine body 1, making it more flexible.

[0026] Furthermore, the cover plates 10 are symmetrically arranged at both ends of the fatigue testing machine body 1. The cover plates 10 are configured to be hollow stainless steel, which has both good corrosion resistance and the advantage of being lightweight. The cover plates 10 abut against each other, and the inner walls of the cover plates 10 are covered with a waterproof layer 11. The waterproof layer 11 improves the waterproof performance of the cover plates 10, prevents water from penetrating the cover plates 10, and thus avoids water accumulation in the receiving groove 4.

[0027] Furthermore, an assembly plate 14 is fixed to each side of the cover 10 close to each other, and a connecting seat 15 is fixed to the assembly plate 14 and the fatigue testing machine body 1. A telescopic rod 13 is provided between the connecting seats 15, and both ends of the telescopic rod 13 are connected to the connecting seat 15 through a damping shaft 16. The telescopic rod 13 can be set as a gas spring, which cooperates with the damping shaft 16 to enable the telescopic rod 13 to freely hover at different angles, so that the cover 10 can be opened at different angles and used flexibly.

[0028] Furthermore, the assembly plates 14 are magnetically attracted assembly plates, and adjacent assembly plates 14 have opposite magnetism. Adjacent assembly plates 14 are coated with magnetic coatings with opposite magnetism, so that the two are attracted to each other under the action of magnetic force, thereby promoting the rapid closing of the cover plate 10.

[0029] Furthermore, the telescopic rod 13 is an electric telescopic rod; there is no need to manually adjust the state of the cover 10, which improves the degree of automation;

[0030] Specifically, by setting the assembly plate 14 and the telescopic rod 13, and by setting the telescopic rod 13 as an electric telescopic rod, the angle between the cover 10 and the top of the fatigue testing machine body 1 can be adjusted by controlling the length of the telescopic rod 13, thereby changing the state of the cover 10, so that the cover 10 can be freely switched between the two states of the switch, thereby improving the degree of automation, achieving a dust-proof effect, and being more convenient to use.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
