Description

Technical Field

[0001] This utility model relates to the field of pressure resistance testing technology, specifically a pressure resistance testing device for the outer shell of a security monitoring facility. Background Technology

[0002] Compression resistance is an important indicator for judging the quality of outer packaging products. Compression tests are required during the quality inspection stage after the product is manufactured to determine its qualification. After the outer shell of security monitoring facilities is manufactured, compression resistance tests are usually required.

[0003] For example, a pressure testing device for the casing of a security monitoring facility, with announcement number CN116067795B, utilizes the cooperation between a limiting part and a limiting frustum, and the cooperation between a supporting part and a supporting shaft, combined with the mechanical self-locking performance of a worm gear transmission pair, to enable the test bracket to reliably achieve rotation, thereby flexibly adjusting the pressure test position around the casing to be tested. However, when testing both sides of the casing of the security monitoring facility, this pressure testing device requires testing one side at a time, which takes a considerable amount of time to complete the testing. Furthermore, when limiting the casing of the security monitoring facility, multiple clamping screws need to be rotated by personnel, which also takes a considerable amount of time, thus requiring a significant amount of time to complete the limiting operation of the security monitoring facility casing. Utility Model Content

[0004] The purpose of this invention is to solve the problems that when testing both sides of the housing of a security monitoring device, it is necessary to test one side at a time, which takes a long time to complete the testing. In addition, when the housing pressure test device of the security monitoring facility is used to limit the housing, it is necessary for personnel to rotate multiple clamping screws, which takes a long time to complete the limiting work of the security monitoring device housing. Therefore, this invention proposes a pressure test device for the housing of a security monitoring facility.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pressure resistance testing device for the outer shell of a security monitoring facility is designed, comprising a base and vertical plates. Vertical plates are fixedly connected to both sides of the upper part of the base. A box is fixedly connected to the middle of the upper part of the base. Pressure resistance testing mechanisms are provided on both sides of the box. A limiting mechanism is provided inside the box. A first motor is provided on the upper part of the box. A threaded rod is fixedly connected to the end of the output shaft of the first motor. The outer wall of the threaded rod is threadedly connected to a slider.

[0007] Preferably, each slider output end is fixedly connected to an electric telescopic rod, and each electric telescopic rod output end is fixedly connected to a test pressure head.

[0008] Preferably, the limiting mechanism includes a second motor, a rotating block is fixedly connected to the end of the output shaft of the second motor, connecting rods are movably connected to both sides of the rotating block via pins, sliding plates are movably connected to the outer sides of the connecting rods via pins, the inner walls of the sliding plates are slidably connected to two crossbars, both sides of the crossbars are fixedly connected to the housing, and a limiting plate is fixedly connected above the sliding plates.

[0009] Preferably, the end of the second motor is fixedly connected to the housing, and an inspection door is installed on the front side of the housing.

[0010] Preferably, the pressure testing mechanism includes a third motor and a scale. The output end of the third motor is fixedly connected to a first gear. The outer wall of the first gear meshes with a second gear. The left side of the transmission shafts of the first and second gears is rotatably connected to the left vertical plate through bearings. The right side of the transmission shafts of the first and second gears is fixedly connected to a curved plate. The outer wall of the right protrusion of the curved plate is rotatably connected to the right vertical plate through bearings. The end of the protrusion of the curved plate is fixedly connected to a pointer.

[0011] Preferably, the scale is machined on the outside of the right vertical plate, and the end of the third motor is fixedly connected to the left vertical plate.

[0012] Preferably, both sides of the bent plate are rotatably connected to the threaded rod via bearings, and the inner wall of the bent plate is slidably connected to the slider.

[0013] Preferably, the left side of the curved plate is fixedly connected to the first motor.

[0014] The present invention proposes a pressure resistance testing device for the outer shell of a security monitoring facility. The beneficial effects are as follows: through the cooperation of the housing and the limiting mechanism, the output shaft of the second motor rotates forward to drive the rotating block to rotate, thereby driving the connecting rods on both sides to move. The movement of the connecting rods causes the sliding plate to slide along the outer wall of the crossbar. The movement of the sliding plate causes the limiting plate to move inward synchronously. When the inner side of the limiting plate is in contact with the outer shell of the security monitoring facility to be tested, the second motor is turned off so that the limiting plates on both sides can move synchronously. The limiting work of the outer shell of the security monitoring facility to be tested can be completed in a short time.

[0015] With the cooperation of the vertical plate and the pressure testing mechanism, the output shaft of the third motor rotates, driving the first gear to rotate, which in turn drives the second gear to rotate. The rotation of the first and second gears drives the two curved plates to rotate, and the rotation of the curved plates drives the pointer to rotate outward synchronously. After the pointer rotates 90 degrees, the level of the pressure head can be observed through the scale to ensure that both sides of the security monitoring facility's casing are tested. The third motor is then turned off to allow simultaneous testing of the points on both sides of the security monitoring facility's casing, thus completing the testing of both sides of the security monitoring facility's casing in a shorter time.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] See attached document Figure 1-6In this embodiment, a pressure resistance testing device for the outer shell of a security monitoring facility includes a base 1 and a vertical plate 4. The vertical plate 4 is fixedly connected to both sides of the upper part of the base 1. A box 2 is fixedly connected to the middle of the upper part of the base 1.

Limiting plates 306 are fixedly connected above the slide plates 304. The end of the second motor 301 is fixedly connected to the housing 2.

The rotation of the output shaft of the second motor 301 drives the rotating block 302 to rotate, thereby driving the connecting rods 303 on both sides to move.

[0028] Working principle:

[0029] Using a pressure resistance testing device for the enclosure of security monitoring facilities:

[0030] When a pressure test needs to be conducted on the top of the casing of a security monitoring facility:

[0031] The operator places the security monitoring facility casing to be tested directly below one of the test heads 6, roughly between the upper surface of the second housing 2 and the two limiting plates 306. Even if the casing is placed slightly off-center, the two test heads 6 can sequentially test both sides of the casing (the test head 6 that contacts the casing first is tested first). Then, the second motor 301 (a servo motor with a self-locking function) is started, and the output shaft of the second motor 301... The rotating block 302 rotates, thereby moving the connecting rods 303 on both sides. The movement of the connecting rods 303 causes the sliding plate 304 to slide along the outer wall of the crossbar 305. The movement of the sliding plate 304 causes the limiting plate 306 to move inward synchronously. When the inner side of the limiting plate 306 is in contact with the outer shell of the security monitoring facility to be tested, the second motor 301 is turned off. Through the self-locking function of the second motor 301, the position of the limiting plates 306 on both sides is fixed, so that the limiting plates 306 on both sides can move synchronously. The limiting work of the outer shell of the security monitoring facility to be tested can be completed in a short time.

[0032] Start the corresponding first motor 9 (the first motor 9 is a servo motor with a self-locking function). The output shaft of the first motor 9 rotates, which drives the threaded rod 10 to rotate. The bending plate 504 can limit the rotation of the slider 8. When used in conjunction with the threaded rod 10, the slider 8 can only move left and right, which in turn can drive the test pressure head 6 to move left and right.

[0033] When the electric telescopic rod 7 is activated, the output end of the electric telescopic rod 7 extends and retracts, which can drive the test pressure head 6 to move up and down.

[0034] The test head 6 is moved to the required position on the outer shell of the security monitoring facility under test by the first motor 9. Then, the output end of the electric telescopic rod 7 is moved to drive the test head 6 (which is connected to an external pressure sensor via a wire) to contact the outer shell of the security monitoring facility under test. The pressure sensor measures the pressure. If the pressure applied reaches the specified pressure threshold of a qualified product and the shell has not deformed or broken, it means that the test position meets the product requirements. Conversely, if the shell deforms or breaks, it means that the test position does not meet the product requirements. After the test is completed, the operator controls the first motor 9 and the electric telescopic rod 7 to return the test head 6 to its initial position. Then, the output shaft of the second motor 301 is reversed to move the limit plates 306 on both sides away from the outer shell of the security monitoring facility under test. Finally, the outer shell of the security monitoring facility under test can be removed.

[0035] When it is necessary to conduct pressure resistance tests on both sides of the outer shell of a security monitoring facility:

[0036] Referring to the method for pressure testing of the top of the security monitoring facility's casing, the casing to be tested is limited. Then, the operator starts the third motor 501. The output shaft of the third motor 501 rotates, driving the first gear 502 to rotate, which in turn drives the second gear 503 to rotate. The rotation of the first gear 502 and the second gear 502 drives the two curved plates 504 to rotate. The rotation of the curved plates 504 drives the pointer 505 to rotate outward synchronously. After the pointer 505 rotates 90 degrees, the level of the testing head 6 can be observed through the scale 507 to test the front and back sides of the security monitoring facility's casing (if pressure testing of the left and right sides of the security monitoring facility's casing is required, the clamp can be released, the security monitoring facility's casing can be rotated 90 degrees, and the above operation can be repeated to test the left and right sides). The third motor 501 is then turned off, and the third motor 501 is connected to the control panel of the right vertical plate 4 (e.g., Figure 1 The third motor 501 can be started and stopped via the control panel, eliminating the need for operators to run to the other side to turn it off. The third motor 501 is a servo motor with a self-locking function. The self-locking of the third motor 501 fixes the position of the two curved plates 504, enabling simultaneous detection of points on both sides of the security monitoring facility's outer shell. This allows the detection of both sides of the security monitoring facility's outer shell to be tested to be completed in a shorter time.

[0037] The first motor 9 is a servo motor of the same model. The two first motors 9 are connected to a PLC controller. The first motors 9 can be started simultaneously or individually through programming. By starting the two first motors 9 and the electric telescopic rod 7 at the same time, the test pressure head 6 is moved. Then, referring to the judgment method for pressure resistance testing on the top of the security monitoring facility shell, it is determined whether the test points on both sides of the security monitoring facility shell are qualified. After the test is completed, the operator controls the first motor 9, the electric telescopic rod 7 and the third motor 501 to make the test pressure head 6 return to the initial position. Then, the output shaft of the second motor 301 is reversed, which moves the limit plates 306 on both sides away from the security monitoring facility shell. Then, the security monitoring facility shell after the test can be removed.
