Description

Technical Field

[0001] This invention relates to the field of optical cable distribution equipment technology, and in particular to a device and method for testing the mechanical strength of a housing. Background Technology

[0002] Fiber optic distribution equipment is a device used for storing, connecting, and distributing fiber optic cables, typically installed outdoors or in a server room. It protects the cables from mechanical damage, temperature variations, and humidity, and provides a centralized interface for connecting and switching different cables. Simultaneously, it manages the cables and detects signals, facilitating maintenance and troubleshooting. In fiber optic communication systems, fiber optic distribution equipment is a crucial component.

[0003] The optical cables stored in optical cable distribution equipment are made of a very fragile material, requiring high mechanical strength. Excessive mechanical pressure or compression can easily cause fiber breakage or damage, affecting the transmission quality and stability of optical signals. Therefore, to ensure the safety and reliability of the optical cables within the enclosure, mechanical strength testing is essential. Mechanical strength testing of the enclosure allows for the assessment of its resistance to compression, extrusion, and tension, enabling timely detection and repair of problems, thereby improving the equipment's lifespan and stability, and ensuring the normal operation of the optical communication system. However, existing technologies lack specialized testing equipment for assessing the mechanical strength of the enclosures, making the testing process cumbersome and labor-intensive. Therefore, this invention is proposed. Summary of the Invention

[0022] A method for testing the mechanical strength of a housing, comprising the following steps:

[0024] S2. Place a counterweight inside the stamping box;

[0025] S3. Control the sector gear to rotate, so that it drives the rack plate that meshes with it to move, thereby moving the stamping box upward;

[0026] S4. When the sector gear and the rack plate are not meshed, the stamping box will fall under the action of gravity, so that the stamping block will fall on the box to be tested, and thus the box to be tested will be stamped.

[0031] 1. This mechanical strength testing device for the box body controls the rotation of the sector gear, which drives the meshing rack plate to move, thereby moving the stamping box upward. When the sector gear and the rack plate are not meshed, the stamping box will fall under the action of gravity, so that the stamping block falls on the box body to be tested, thereby performing a stamping test on the box body to be tested. It can perform reciprocating tests to observe the mechanical strength of the box body to be tested.

[0032] 2. The mechanical strength testing device for the box body, when the sector gear rotates to stamp the box, will drive the cam to rotate, thereby causing the cylinder to reciprocate and collect gas, which is then delivered into the cylinder. Then, by pushing the second piston, the toothed block on the pressure plate will move, and the toothed block will move to mesh with the gear block, thereby limiting the gear block and preventing it from rotating. This prevents the threaded rod from rotating and further completes the limiting operation of the clamping plate, thus improving the fixing effect of the box body to be tested.

This invention can effectively complete the mechanical strength test of the box, and can facilitate the adjustment of the weight of the stamping box, improve the test effect, ensure the safety of the optical fiber inside the box, and improve its service life.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0046] Example 1:

[0047] Reference Figures 1-9 A box-type mechanical strength testing device includes a base plate 1 and a box 102 to be tested placed on the base plate 1, and two upright plates 103 fixedly connected to the base plate 1; a stamping box 4 slidably connected between the two upright plates 103, with a counterweight 409 inside the stamping box 4 and a stamping block 410 fixedly connected to the bottom of the stamping box 4; two clamping plates 203, both slidably connected to the base plate 1, and the two clamping plates 203 are respectively placed on both sides of the box 102 to be tested; a rotating shaft 301 rotatably connected to the upright plates 103; a sector gear 302 fixedly connected to the outer wall of the rotating shaft 301; a rack plate 402 fixedly connected to the outer wall of the stamping box 4, and the sector gear 302 meshes with the rack plate 402; and a locking element for limiting the clamping plates 203 is provided on the bottom outer wall of the upright plates 103.

[0048] In this embodiment, during use, the test chamber 102 is first placed on the base plate 1. The test chamber 102 is the chamber itself. It is then fixed by two clamping plates 203. Next, the sector gear 302 is rotated, causing it to move the meshing rack plate 402, thus moving the stamping box 4 upwards. When the sector gear 302 and rack plate 402 are not meshed, the stamping box 4 falls under gravity, causing the stamping block 410 to fall onto the test chamber 102, thus performing a stamping test on the test chamber 102. It should be noted that the rotation speed of the sector gear 302 is relatively slow. When the sector gear 302 and rack plate 402 are not meshing... When the pressure box 4 is engaged, the force of gravity will cause it to fall faster. When the sector gear 302 meshes with the rack plate 402 again, the stamping block 410 has completed the stamping, which allows for better testing of the mechanical strength of the box 102 to be tested. When the sector gear 302 meshes with the rack plate 402 again, the pressure box 4 can be raised again. When the two are not engaged, the stamping test can be performed again. This process can be repeated to observe the mechanical strength of the box 102 to be tested. At the same time, while the sector gear 302 is rotating, the locking device can limit the two clamping plates 203 to prevent them from moving and causing the box 102 to be tested to become unstable, thus affecting the test results.

[0049] Furthermore, a counterweight 409 is provided inside the stamping box 4, and different numbers of counterweights 409 can be placed to increase the overall weight of the stamping box 4, thereby enabling the detection of the deformation of the box 102 under different weights and obtaining the ultimate stress condition of the box 102.

[0050] Example 2:

[0051] Reference Figures 1-9 A box-type mechanical strength testing device includes a base plate 1 and a box 102 to be tested placed on the base plate 1, and two upright plates 103 fixedly connected to the base plate 1; a stamping box 4 slidably connected between the two upright plates 103, with a counterweight 409 inside the stamping box 4 and a stamping block 410 fixedly connected to the bottom of the stamping box 4; two clamping plates 203, both slidably connected to the base plate 1, and the two clamping plates 203 are respectively placed on both sides of the box 102 to be tested; a rotating shaft 301 rotatably connected to the upright plates 103; a sector gear 302 fixedly connected to the outer wall of the rotating shaft 301; a rack plate 402 fixedly connected to the outer wall of the stamping box 4, and the sector gear 302 meshes with the rack plate 402; and a locking element for limiting the clamping plates 203 is provided on the bottom outer wall of the upright plates 103.

[0052] Two baffles 2 are fixedly connected to both ends of the base plate 1. A threaded rod 201 and a guide rod 202 are respectively connected to the two baffles 2. The threaded rod 201 is rotatably connected to the baffle 2, and the guide rod 202 is fixedly connected to the baffle 2. The threads at both ends of the threaded rod 201 are opposite in direction. Both clamping plates 203 are provided with threaded seats 204, and both clamping plates 203 are threadedly connected to both ends of the threaded rod 201 through the threaded seats 204. A slide rail 101 is provided on the base plate 1, and the clamping plates 203 are slidably connected to the slide rail 101.

[0053] One of the baffles 2 has a first motor 205 on its outer wall, and a threaded rod 201 is located at the output end of the first motor 205. A second motor 3 is located on the vertical plate 103, and a rotating shaft 301 is located at the output end of the second motor 3.

[0054] In this embodiment, the first motor 205 is started, thereby driving the threaded rod 201 at the output end to rotate. Since the threads at both ends of the threaded rod 201 turn in opposite directions, it can drive the two threaded seats 204 to move closer to each other, thereby causing the two clamping plates 203 to move closer to each other and clamp the box 102 to be tested, thereby limiting and fixing the box 102 to be tested. Furthermore, the first motor 205 can be replaced by a manual handle. By rotating the handle, the two clamping plates 203 are moved to limit the box 102 to be tested. This can be selected as appropriate. Moreover, the first motor 205 is a servo motor, which can realize forward and reverse operation. When the first motor 205 rotates in the reverse direction, it can move the two clamping plates 203 away from each other, thereby allowing the box 102 to be tested to be taken out. The position of the two clamping plates 203 will not affect the insertion and removal of the box 102 to be tested.

[0055] Starting the second motor 3 drives the rotating shaft 301 to rotate, thereby causing the sector gear 302 to rotate and mesh with the rack plate 402 to move the stamping box 4, thus enabling the stamping block 410 to complete the stamping operation. This allows for reciprocating testing to observe the mechanical strength of the box 102 under test, resulting in better testing results.

[0056] Example 3:

[0057] Reference Figures 1-9A box-type mechanical strength testing device includes a base plate 1 and a box 102 to be tested placed on the base plate 1, and two upright plates 103 fixedly connected to the base plate 1; a stamping box 4 slidably connected between the two upright plates 103, a counterweight 409 provided inside the stamping box 4, and a stamping block 410 fixedly connected to the bottom of the stamping box 4; two clamping plates 203, both slidably connected to the base plate 1, and the two clamping plates 203 are respectively placed on both sides of the box 102 to be tested; a rotating shaft 301 rotatably connected to the upright plates 103; a sector gear 302 fixedly connected to the outer wall of the rotating shaft 301; a rack plate 402 fixedly connected to the outer wall of the stamping box 4, and the sector gear 302 meshes with the rack plate 402; and a locking element for limiting the clamping plates 203 is provided on the bottom outer wall of the upright plates 103.

[0058] A fixing block 403 is fixedly connected to the inner wall of the upright plate 103. An arc plate 401 is connected to the end of the fixing block 403 away from the upright plate 103. A fixing rod 404 is fixedly connected to the arc plate 401. The stamping box 4 is slidably connected inside the arc plate 401.

[0059] A lead screw 407 is fixedly connected inside the stamping box 4. A counterweight 409 is slidably connected to the lead screw 407. A locking block 408 is threaded onto the lead screw 407. A connecting rod 405 is fixedly connected to the top outer wall of the stamping box 4. A stop bar 406 is fixedly connected to the connecting rod 405. A bearing plate 104 corresponding to the stop bar 406 is fixedly connected to the top outer wall of the upright plate 103.

[0060] In this embodiment, the arc-shaped plate 401 can limit the movement of the stamping box 4, making it easier to move. The fixed block 403 and the fixed rod 404 can make the arc-shaped plate 401 more stable, thus making the sliding of the stamping box 4 more stable. When a counterweight 409 is added, it is placed on the lead screw 407, and then a locking block 408 is threaded onto the lead screw 407 to abut against the counterweight 409, thereby fixing the counterweight 409 and completing the counterweight operation.

[0061] Furthermore, the top of the stamping box 4 is connected to a stop bar 406 via a connecting rod 405. When the device is not in use, the stop bar 406 will be placed on the support plate 104 to support the stamping box 4 and prevent it from slipping.

[0062] Example 4:

[0063] Reference Figures 1-9A box-type mechanical strength testing device is basically the same as that in Embodiment 3. Furthermore, the rotating shaft 301 is rotatably connected to a cam 303 at one end outside the upright plate 103. A support block 5 is fixedly connected to the outer wall of the upright plate 103. A cylinder 501 is fixedly connected between the outer walls of both sides of the support block 5 and the upright plate 103. A first piston 502 is slidably connected inside the cylinder 501. A first support rod 503 is connected to the outer wall of the first piston 502. A push plate 504 is fixedly connected to the end of the first support rod 503 away from the first piston 502. The push plate 504 is connected to the cam 303.

[0064] The outer wall of the cam 303 is provided with a slide groove 304. The outer wall of the push plate 504 is fixedly connected to a support plate 507. The support plate 507 is provided with a connecting shaft 508. The connecting shaft 508 is rotatably connected to a side plate 305. The side plate 305 is fixedly connected to a fixing column 306. The fixing column 306 is slidably connected in the slide groove 304.

[0065] In this embodiment, when the second motor 3 is started and drives the rotating shaft 301 to rotate, it will not only drive the sector gear 302 to rotate to realize the stamping operation, but also drive the cam 303 to rotate. When the cam 303 rotates, the fixed column 306 will slide in the slide groove 304. When the fixed column 306 slides to correspond to the highest point of the cam 303, it will drive the push plate 504 to move through the side plate 305 and the support plate 507, thereby pushing the first piston 502 to move deeper into the cylinder 501 through the first support rod 503, thereby transporting the gas in the cylinder 501 to the gas outlet pipe 506, so that it enters the cylinder 6. The side plate 305 and the support plate 507 are rotatably connected, which allows the fixed column 306 to slide better in the slide groove 304 and prevents jamming.

[0066] Under the action of the fixed column 306, the push plate 504 can move with the rotation of the cam 303, thereby enabling the first piston 502 to reciprocate within the cylinder 501. The cylinder 501 will draw air through the air inlet 505 and discharge air through the air outlet 506, thus cyclically transporting gas into the cylinder 6. Both the air inlet 505 and the air outlet 506 are equipped with one-way valves, which can ensure that the air inlet 505 can only allow air to enter and not exit, and that the air outlet 506 can only allow air to exit and not enter, making it easier to use.

[0067] The locking component includes a cylinder 6 fixedly connected to the upright plate 103. A second piston 601 is slidably connected inside the cylinder 6. A second support rod 602 is fixedly connected to the outer wall of the second piston 601. A groove 105 is provided on the inner wall of the upright plate 103. One end of the second support rod 602 away from the second piston 601 is placed in the groove 105 and connected to a sliding plate 604. A pressure plate 605 is connected to the outer wall of the sliding plate 604 through a telescopic rod 607. A toothed block 606 is provided on the outer wall of the pressure plate 605. A gear block 206 is fixedly connected to the outer wall of the threaded rod 201. The toothed block 606 meshes with the gear block 206.

[0068] The top of the cylinder 501 is provided with an air inlet 505, and the bottom of the cylinder 501 is provided with an air outlet 506. The end of the air outlet 506 away from the cylinder 501 is connected to the cylinder 6. Both the air inlet 505 and the air outlet 506 are provided with one-way valves. The outer wall of the second support rod 602 is fitted with a spring 603, and the spring 603 is located between the second piston 601 and the outer wall of the vertical plate 103.

[0069] In this embodiment, when gas enters the cylinder 6, it pushes the second piston 601 to move, thereby driving the slide plate 604 to move within the groove 105 via the second support rod 602. This causes the pressure plate 605 to drive the toothed block 606 to move, and then the toothed block 606 moves to mesh with the gear block 206, thereby limiting the gear block 206 and preventing it from rotating. This also prevents the threaded rod 201 from rotating, further completing the limiting operation of the clamping plate 203, thus improving the fixing effect of the test box 102. A telescopic rod 607 is provided between the slide plate 604 and the pressure plate 605, which can provide a certain buffer between the slide plate 604 and the pressure plate 605. A pressure relief valve is provided on the outer wall of the cylinder 6. When not in operation, the gas can be discharged through the pressure relief valve. The spring 603 can automatically reset the second piston 601, thereby automatically resetting the toothed block 606 and preventing it from meshing with the gear block 206, which facilitates subsequent work.

[0070] Example 5:

[0071] A method for testing the mechanical strength of a housing, comprising the following steps:

[0072] S1. First, the box to be tested 102 is placed on the base plate 1 and limited by two clamps 203;

[0073] S2. Place counterweight 409 inside the stamping box 4;

[0074] S3. Control the sector gear 302 to rotate, so that it drives the rack plate 402 that meshes with it to move, thereby moving the stamping box 4 upward;

[0075] S4. When the sector gear 302 and the rack plate 402 are not meshed, the stamping box 4 will fall under the action of gravity, so that the stamping block 410 falls on the box 102 to be tested, and thus the box 102 to be tested is stamped.

[0076] S5. The sector gear 302 reciprocates and meshes with the rack plate 402, which can drive the stamping block 410 to reciprocate to perform stamping operation on the box 102 to be tested, and observe the deformation effect.

[0077] S6. While the sector gear 302 moves, the locking component can limit the clamping plate 203, thereby limiting the test box 102.

[0078] S7. Record the stamping results and conditions, and complete the inspection.

[0079] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
