Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a low-temperature resistance detection device for an aneroid barometer. Background Technique

[0002] In many industrial fields, aneroid barometers often need to work in low-temperature environments. For example, in aerospace, petrochemical, cryogenic engineering and other fields, equipment may face extremely low temperature conditions. In order to ensure that aneroid barometers can accurately and reliably measure pressure in these special environments, it is crucial to detect their low-temperature resistance performance.

[0003] Traditional detection instruments cannot simultaneously detect whether the air pressure is normally displayed and whether the internal components are completely installed during detection. When detecting in batches, not only are the steps cumbersome, but also the detection efficiency is reduced.

[0004] In view of this, in response to the existing problems, research and improvement are carried out to provide a low-temperature resistance detection device for an aneroid barometer, with reasonable structural design, high stability, and taking into account various aspects of application. The purpose is to solve problems and improve practical value through this technology. Content of the Utility Model

[0005] The utility model realizes a low-temperature resistance detection device for an aneroid barometer by fixing the pressure gauge and repeatedly colliding while inflating the inside to detect whether the internal components can be used normally when being impacted.

[0007] Preferably: the slide rail is equal in length to the operating table, and both ends of the slide rail are aligned with both ends of the operating table. The center of the upper end of the fixed platform has a refrigeration effect, and a groove is arranged at the center.

[0008] Preferably, two groups of support blocks are fixedly connected to both sides of the upper end of the fixed platform. The spring rods are fixedly connected to the centers of the support blocks, and the two spring rods are matched with each other. The inner diameter of the buckle matches the outer diameter of the pressure gauge to be detected, and the buckle is opened wider on the side close to the air pressure pipe.

[0009] Preferably, two groups of fixed blocks are fixedly connected to both ends of the slide rail, and the fixed blocks are aligned with the operating table. The connecting block is fixedly connected to one side of the fixed platform. The threaded rod is connected to the output end of the motor, and the fixed platform drives the connecting block to move by rotating the threaded rod through the motor.

[0010] Preferably, the air pressure pipe is matched with the connection part of the pressure gauge, and the air pressure pipe can be adjusted in position movably. The connecting rod is movably connected to one end of the air pressure pipe, and the connecting rod is connected to the valve inside the air pressure pipe. The valve controls the opening and closing size by driving the connecting rod when rotating through the gear.

[0011] Preferably, the rack is fixedly connected to the upper end of the operating table, and the rack meshes with the gear. The air pressure pipe can be adjusted in position movably through the fixed teeth.

After the fixing is completed, the air pressure pipe is moved to be connected with the connection part of the pressure gauge. After the connection is completed, the motor is turned on. When the motor rotates the threaded rod to move the fixed platform, the air pressure pipe will move synchronously when the fixed platform moves. Because the air pressure pipe moves forward to be connected with the pressure gauge, when the pressure gauge moves forward, it will drive the gear to move forward synchronously, so as to be connected with the rack. When the air pressure pipe moves, it will drive the gear to rotate. When the gear contacts the rack, it will control the opening and closing of the valve inside the air pressure pipe through the rotation of the gear. Thus, when performing the mobile detection, the air pressure gauge is inflated to detect whether the air pressure gauge can display the value normally under low temperature and vibration environments.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] Refer to Figures 1-4, an embodiment provided by the present utility model: a low-temperature detection device for a diaphragm pressure gauge, including an operation table 1. At the center of the upper end of the operation table 1, a slide rail 2 for guiding is provided. A fixed platform 3 for detection is movably connected to the upper end of the slide rail 2. On both sides of the upper end of the fixed platform 3, support blocks 4 for increasing stability are provided. On one side of the support block 4 close to the center of the fixed platform 3, a spring rod 5 is fixedly connected. At the end of the spring rod 5 away from the connection, a buckle 6 for fixing is fixedly connected. At the positions where both ends of the slide rail 2 are connected to the operation table 1, fixed blocks 7 are provided. On one side of the fixed platform 3, a connection block 8 for driving is provided. A threaded rod 9 is connected through the center of the connection block 8. At one end of the threaded rod 9, a motor 10 for driving is provided. On the side of the fixed platform 3 away from the connection block 8, a pneumatic tube 11 is provided. The lower end of the pneumatic tube 11 is movably connected to a connecting rod 12. At the end of the connecting rod 12 away from the connection, a gear 13 for rotating is fixedly connected. On one side of the gear 13, a rack 14 meshing with the gear 13 is provided. At the lower end of the pneumatic tube 11, a fixed tooth 15 for adjustment is provided. On one side of the fixed tooth 15, a push rod 16 for opening is provided.

[0023] In an alternative embodiment: The slide rail 2 is equal in length to the operation table 1, and both ends of the slide rail 2 are aligned with both ends of the operation table 1. The slide rail 2 provides a guiding function for the fixed platform 3 during movement, improving the stability of the fixed platform 3 during movement. The center of the upper end of the fixed platform 3 has a refrigeration effect, and a groove is provided at the center to fix the pressure gauge and detect whether it can operate normally under low-temperature conditions.

[0024] In an alternative embodiment: Two groups of support blocks 4 are fixedly connected to both sides of the upper end of the fixed platform 3, which provide support for the spring rod 5 when fixing the pressure gauge. The spring rod 5 is fixedly connected to the center of the support block 4, and the two groups of spring rods 5 are matched. The inner diameter of the buckle 6 matches the outer diameter of the pressure gauge to be detected. The buckle 6 is opened wider on the side close to the pneumatic tube 11 to prevent the pressure gauge from being unable to be fixed due to the protrusion at the connection when it is completely attached.

[0025] In an alternative embodiment: Two groups of fixed blocks 7 are fixedly connected to both ends of the slide rail 2, and the fixed blocks 7 are aligned with the operation table 1. The connection block 8 is fixedly connected to one side of the fixed platform 3. The threaded rod 9 is connected to the output end of the motor 10. The fixed platform 3 drives the connection block 8 to move by rotating the threaded rod 9 through the motor 10. When the motor 10 controls the fixed platform 3 to reciprocate, the fixed platform 3 will continuously hit the fixed blocks 7 at both ends during the reciprocating movement, thereby vibrating the pressure gauge fixed on the upper end of the fixed platform 3, so as to detect whether its internal components operate normally under external factors.

[0026] In an optional embodiment: the air pressure tube 11 matches the connection of the pressure gauge, and the air pressure tube 11 is movably adjustable, the connecting rod 12 is movably connected to one end of the air pressure tube 11, and the connecting rod 12 is connected to the internal valve of the air pressure tube 11. When the valve rotates through the gear 13, the transmission connecting rod 12 controls the size of the opening and closing. The staff fixes the pressure gauge through the buckle 6, and after the fixation is completed, the air pressure tube 11 is moved to connect with the connection of the pressure gauge. After the connection is completed, the motor 10 is turned on. When the motor 10 rotates the threaded rod 9 to move the fixed platform 3, because the air pressure tube 11 is connected to the fixed platform 3, the air pressure tube 11 will be driven to move synchronously when the fixed platform 3 moves. 11 is pushed forward and connected to the pressure gauge. When the pressure gauge moves forward, it will drive the gear 13 to move forward synchronously, thereby connecting with the rack 14. When the air pressure tube 11 moves, it will drive the gear 13 to rotate. When the gear 13 contacts the rack 14, the rotation of the gear 13 will control the opening and closing of the internal valve of the air pressure tube 11. During the mobile detection, the inside of the air pressure gauge is inflated to detect whether the air pressure gauge can display the value normally under low temperature and vibration environment. When the detection is completed, the staff presses the push rod 16 to take the air pressure tube 11 backward, thereby separating it from the pressure gauge. If the pressure gauge and inflation detection are not needed during the detection, the air pressure tube 11 does not need to be connected to the pressure gauge.

[0027] In an optional embodiment: the rack 14 is fixedly connected to the upper end of the operating table 1, and the rack 14 is meshed with the gear 13. The air pressure tube 11 can be movably adjusted in position by fixing the locking teeth 15, so as to improve the detection efficiency and thus improve the product quality.

[0028] In an optional embodiment: the fixed teeth 15 are connected by two groups of teeth, and the two groups of teeth are placed oppositely. The push rod 16 is fixedly connected to the side of the teeth away from the teeth connected to the air pressure tube 11, and the air pressure tube 11 is retracted by pressing the push rod 16. Because the two groups of teeth are connected in reverse and the fixed teeth 15 connected to the air pressure tube 11 are facing upward, when the air pressure tube 11 is pushed forward, the caliper connected to the air pressure tube 11 cannot be fixed with the other group of fixed teeth 15. After the fixed teeth 15 are pushed forward, the air pressure tube 11 cannot be pulled out due to the engagement of the two groups of teeth, thereby fixing it. After the detection is completed, the push rod 16 is pressed, and the push rod 16 will push away the fixed teeth 15 that are not connected to the air pressure tube 11, thereby disengaging it from the engagement state, so that the air pressure tube 11 can be taken out.

[0029] Working principle and process: The staff fixes the pressure gauge through the buckle 6. After the fixation, the air pressure pipe 11 is connected to the pressure gauge. After completion, the motor 10 is turned on. The motor 10 drives the connecting block 8 to move by rotating the threaded rod 9, thereby driving the fixed platform 3 to reciprocate on the slide rail 2. When the fixed platform 3 reciprocates, it will continuously impact the fixed blocks 7 at both ends of the slide rail 2. When the fixed platform 3 moves, it will synchronously drive the air pressure pipe 11 to move. When the air pressure pipe 11 moves, it will rotate the gear 13 through the rack 14, thereby controlling the opening and closing of the valve inside the air pressure pipe 11.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
