Technical Field

[0001] This utility model relates to the field of mechanical testing technology, specifically a device for testing the durability of handles in equipment cabinets and boxes. Background Technology

[0002] Equipment cabinet handle durability testing device is a specialized automated or semi-automated testing device. Its core function is to simulate the action of a human hand repeatedly operating the handle. Through preset number of cycles, force and frequency, it comprehensively evaluates the structural strength, fatigue life, wear degree and overall reliability of the handle.

[0003] In the current market, the durability testing devices for cabinet handles that are widely used can usually only perform durability tests on handles produced in the same batch. However, when the testing needs are expanded to evaluate the durability of handles of different sizes, specifications or models, the existing testing devices often lack flexibility and adaptability, making it difficult to ensure the accuracy and reliability of the test results. This limitation not only reduces testing efficiency, but may also have an adverse impact on product quality control and improvement.

[0004] Therefore, this utility model provides a device for testing the durability of equipment cabinet handles to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a durability testing device for cabinet handles, comprising a fixed frame, a support frame fixedly mounted on the fixed frame, a handle body fixedly mounted on the support frame by bolts, a rotating block rotatably mounted on one side of the support frame, a clamping plate slidably mounted inside the rotating block, a plug rod fixedly mounted on one side of one of the clamping plates, a control groove opened inside the other clamping plate, and a clamping mechanism disposed inside the control groove for clamping different handle bodies.

[0007] The clamping mechanism includes a fixed cylinder fixedly installed inside the control groove, a telescopic rod fixedly installed on the inner wall of the control groove, an insert block fixedly installed on the movable end of the telescopic rod, a first spring sleeved on the side surface of the telescopic rod, a pressing block slidably installed inside the control groove, and an inclined block fixedly installed on one side of the pressing block.

[0008] As a further optimization, the insertion rod is inserted into the inside of the fixed cylinder, and the side surface of the insertion rod is provided with a plurality of slots for the insertion block to be inserted into, and the slots are distributed in a linear array on the insertion rod.

[0009] As a further optimization, one end of the first spring is fixedly connected to one side of the insert block, and the other end of the first spring is fixedly connected to the inner wall of the control groove. Multiple inclined blocks are provided, and the inclined surface of the inclined block is in contact with the inclined surface of the insert block.

[0010] As a further optimization, a second spring is sleeved on the side surface of the fixed cylinder, and a pad is slidably connected to the side surface of the fixed cylinder. The ends of the plurality of inclined blocks away from the pressing block are in contact with one side of the pad.

[0011] As a further optimization, one end of the second spring is fixedly connected to the inner wall of one side of the control groove, and the other end of the second spring is fixedly connected to the side of the pad away from the inclined block.

[0012] As a further optimization, a fixing rod is fixedly connected inside the rotating block.

[0014] Compared with existing technologies, this utility model has a simple structure and is easy to use. Through the clamping mechanism, when it is necessary to clamp handles of different sizes, pressing the pressing block moves the inclined block, which squeezes the insert block, thereby driving the telescopic rod to retract and disengage the insert block from the slot. At this time, the two clamping plates can be pulled to pull the insert rod out of the fixed cylinder, and the distance between the two clamping plates can be adjusted. After the distance is adjusted, the pressing block is released. Under the elastic force of the first spring, the telescopic rod drives the insert block to reset, the inclined block loses its squeezing force, the insert rod is reinserted into the fixed cylinder, and the insert block is also inserted into the corresponding slot. This improves flexibility and adaptability, ensures the accuracy and reliability of test results, and improves test efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a device for testing the durability of handles in equipment cabinets and boxes, such as... Figures 1 to 5 As shown, it includes a fixed frame 1, a support frame 2 fixedly mounted on the fixed frame 1, a handle body 3 fixedly mounted on the support frame 2 by bolts, a rotating block 4 rotatably mounted on one side of the support frame 2, a clamping plate 6 slidably mounted inside the rotating block 4, a plug rod 7 fixedly mounted on one side of one of the clamping plates 6, a control groove 8 opened inside the other clamping plate 6, and a clamping mechanism provided inside the control groove 8 for clamping different handle bodies 3.

[0023] The clamping mechanism includes a fixed cylinder 9 fixedly installed inside the control groove 8, a telescopic rod 10 fixedly installed on the inner wall of the control groove 8, an insert block 11 fixedly installed on the movable end of the telescopic rod 10, a first spring 12 sleeved on the side surface of the telescopic rod 10, a pressing block 13 slidably installed inside the control groove 8, and an inclined block 14 fixedly installed on one side of the pressing block 13.

[0024] The insertion rod 7 is inserted into the inside of the fixed cylinder 9. The side surface of the insertion rod 7 has multiple slots for the insertion block 11 to be inserted into. The slots are arranged in a linear array on the insertion rod 7.

[0025] One end of the first spring 12 is fixedly connected to one side of the insert block 11, and the other end of the first spring 12 is fixedly connected to the inner wall of the control groove 8. Multiple inclined blocks 14 are provided, and the inclined surface of the inclined block 14 is in contact with the inclined surface of the insert block 11.

[0026] When using this handle durability testing device, first insert the handle body 3 into the two mounting holes on the support frame 2, and then fix it with bolts. When it is necessary to clamp handle bodies 3 of different sizes, press the pressing block 13. The pressing block 13 drives the inclined block 14 to move. The inclined block 14 squeezes the insert block 11. The insert block 11 drives the telescopic rod 10 to retract. At the same time, the first spring 12 is deformed by force and generates elastic force. The insert block 11 disengages from the slot. At this time, the two clamping plates 6 can be pulled to pull the insert rod 7 out of the fixed cylinder 9. Then adjust the distance between the two clamping plates 6. After the distance is adjusted, release the pressing block 13. Under the action of the elastic force of the first spring 12, the telescopic rod 10 drives the insert block 11 to reset. At the same time, the inclined block 14 loses the squeezing force. The insert rod 7 is re-inserted into the fixed cylinder 9, and the insert block 11 is inserted into the corresponding slot, completing the clamping of the handle body 3. This device has a simple structure and is easy to clamp handle bodies 3 of different sizes, improving the practicality of the device.

[0027] In order to facilitate the automatic reset of each component, such as Figure 1 , Figure 3 and Figure 5 As shown, a second spring 15 is sleeved on the side surface of the fixed cylinder 9, and a pad 16 is slidably connected to the side surface of the fixed cylinder 9. The ends of the multiple inclined blocks 14 away from the pressing block 13 are in contact with one side of the pad 16.

[0028] One end of the second spring 15 is fixedly connected to the inner wall of one side of the control groove 8, and the other end of the second spring 15 is fixedly connected to the side of the pad 16 away from the inclined block 14.

[0029] The rotating block 4 is internally fixedly connected to a fixing rod 5, which passes through the clamping plate 6. A third spring 17 is sleeved on the side surface of the fixing rod 5, and the two ends of the third spring 17 are respectively fixedly connected to the opposite sides of the two clamping plates 6.

[0030] When using this handle durability testing device, the two clamping plates 6 are pushed inward along the fixing rod 5, compressing the third spring 17 until the handle body 3 is clamped. Then, the two clamping plates 6 are fixed in place by the cooperation between the insert rod 7 and the control groove 8. When replacing the handle body 3, the two clamping plates 6 are brought into a limiting contact by pressing the pressing block 13 until they are adjusted to the appropriate position. After releasing the pressing block 13, under the elastic force of the second spring 15, the pad 16 drives the inclined block 14 to reset, and the inclined block 14 no longer compresses the insert block 11. At this point, Under the action of the first spring 12, the telescopic rod 10 drives the insert 11 to quickly reset. The insert 11 is re-inserted into the corresponding slot, achieving a stable clamping of the handle body 3. At the same time, under the action of the third spring 17, the two clamping plates 6 move towards the middle. When the clamping of the handle body 3 is released, the limit between the two clamping plates 6 stops. The elastic potential energy of the third spring 17 pushes the two clamping plates 6 back to the initial position, preparing for the next durability test of the handle body 3. The whole reset process is fast and smooth, without the need for manual reset, which improves the testing efficiency.

[0031] Furthermore, to facilitate durability testing of the handle body 3, such as... Figure 1 and Figure 2 As shown, a motor 18 is fixedly connected to one side of the fixed frame 1. The output end of the motor 18 passes through the fixed frame 1 and is fixedly connected to one side of the rotating block 4.

[0032] When in use, the motor 18 starts, driving the rotating block 4 to rotate. The rotating block 4 drives the two clamping plates 6 to rotate synchronously through the fixed rod 5. Since the handle body 3 is firmly clamped between the two clamping plates 6, the handle body 3 will rotate with the rotation of the clamping plates 6, thus simulating the opening and closing action of the handle in actual use. By setting parameters such as the number of rotations, rotation speed, and rotation direction of the motor 18, the durability test conditions of the handle body 3 can be precisely controlled to meet different test requirements. During the test, the wear condition, deformation degree, and whether there is any breakage of the handle body 3 can be observed and recorded to evaluate its durability performance, improve test efficiency, and ensure the accuracy and reliability of the test results.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
