A strength detection device for cable jacket material

Abstract

This utility model belongs to the technical field of cable sheath material testing devices, specifically relating to a strength testing device for cable sheath materials, including a main testing unit with maintenance grooves on both sides of the main testing unit. Through the cooperation of a mounting frame, positioning blocks, sliding blocks, protrusions, springs, and pulling blocks, when the operator needs to maintain the main testing unit through the maintenance grooves, they only need to pinch the two pulling blocks in the sliding groove, bringing them together. This causes the pulling blocks to push the sliding blocks against the spring in the protrusion, causing one end of the sliding blocks to separate from the slot on the positioning block. The positioning block then separates from the positioning groove, allowing the operator to slide the side plate out of the mounting frame without tools, avoiding the need for tools for disassembly and thus facilitating the maintenance of the strength testing device.

Description

Technical Field

[0002] A cable is a conductor made of one or more mutually insulated conductors and an outer insulating protective layer, used to transmit electricity or information from one place to another.

[0003] Cable sheathing material is the outer protective sleeve of a cable, usually made of polymer materials. It protects the conductor, insulation layer, and other components inside the cable. However, during the processing of cable sheathing material, operators use tensile testing machines to test its tensile strength to ensure that the tensile strength of the cable sheathing material meets the usage standards. However, some tensile testing machines have side plates bolted to the inspection ports on both sides of the equipment. When operators need to maintain the equipment through the inspection ports, they need to use tools to operate multiple bolts to remove the side plates before maintenance can be performed. This operation is time-consuming and labor-intensive, thus causing inconvenience to the maintenance of the tensile testing machine.

[0004] Therefore, this utility model provides a strength testing device for cable sheath materials to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a strength testing device for cable sheath materials, aiming to solve the problem that in the existing tensile testing machines, when in use, the operators will fix side plates to the inspection ports on both sides of the equipment with bolts. When the operators need to maintain the equipment through the inspection ports, they need to use tools to operate multiple bolts to remove the side plates before they can carry out maintenance operations. This operation is time-consuming and labor-intensive, thus causing inconvenience to the maintenance operation of the tensile testing machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a strength testing device for cable sheath materials, comprising a main testing unit body, inspection grooves on both sides of the main testing unit body, a mounting frame connected to one side surface of the main testing unit body outside the inspection grooves, a placement groove on the top surface of the mounting frame, a side plate slidably placed inside the placement groove, positioning blocks symmetrically connected to the bottom surface of the side plate, one end of the positioning block extending into the positioning groove, the positioning groove symmetrically opened on the bottom surface of the placement groove, a slot on one end surface of the positioning block, one end of a sliding plug slidably inserted into the slot, a protrusion penetratingly connected to the other end of the sliding plug, the protrusion symmetrically connected to both ends of the sliding groove, the sliding groove being opened on one side surface of the mounting frame, a stand connected to the top surface of the main testing unit body, a penetrating sliding groove on the top surface of the stand, and a transparent protective plate slidably connected inside the sliding groove.

[0007] As a preferred embodiment of the strength testing device for cable sheathing materials according to this utility model, the protrusion is provided with a spring that is penetrated by a sliding insert, and the sliding insert forms an elastic structure with the protrusion through the spring.

[0008] In a preferred embodiment of the present invention, a strength testing device for cable sheathing materials is provided, wherein the sliding insert passes through one end surface of the protrusion and is connected to the pulling block, and the pulling block is connected to the mounting frame via a sliding groove.

[0009] As a preferred embodiment of the strength testing device for cable sheathing materials according to this utility model, the inner surface of the support frame is symmetrically provided with movable grooves, the two ends of the movable groove are connected with bearings, a screw is connected between the two bearings, and one end of the screw extends into the support frame and is fixedly connected to the output end of the motor.

[0010] As a preferred embodiment of the strength testing device for cable sheathing materials according to this utility model, a movable block is threadedly connected to one end of the screw, a connecting groove is provided on one side surface of the movable block, a transparent protective plate is slidably connected inside the connecting groove, and bolts are symmetrically threaded through the front surface of the movable block.

[0011] As a preferred embodiment of the strength testing device for cable sheath material according to this utility model, one end of the bolt is connected to a limiting hole, the limiting hole is opened through the front surface of the bottom end of the transparent protective plate, the bolt is threadedly connected to the fixing hole through the limiting hole, and the fixing hole is opened inside the rear surface of the connecting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the cooperation of a mounting frame, positioning block, sliding insert block, protrusion, spring, and pulling block. When an operator needs to maintain the main body of the testing unit through the inspection slot, they only need to pinch the two pulling blocks in the sliding groove and bring them together. At this time, the pulling block will drive the sliding insert block to squeeze the spring in the protrusion, causing one end of the sliding insert block to separate from the slot on the positioning block. Then, the positioning block can separate from the positioning groove, allowing the operator to slide the side plate out of the mounting frame without tools. This avoids the need for tools to disassemble the device, thus bringing convenience to the maintenance of the strength testing device.

[0014] This invention utilizes the cooperation of a support frame, screw, motor, moving block, and transparent protective plate to install a liftable transparent protective plate on the main testing unit. When the main testing unit is testing cable sheath material, the transparent protective plate can shield the front of the testing position. This prevents debris from splashing towards the operator during the testing process, thus improving the safety of the strength testing device. 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] Please see Figures 1-4 This utility model provides the following technical solution: a strength testing device for cable sheath materials, including a testing host body 1, inspection grooves 2 are provided on both sides of the testing host body 1, a mounting frame 3 is connected to one side surface of the testing host body 1 outside the inspection grooves 2, a placement groove 4 is provided on the top surface of the mounting frame 3, a side plate 5 is slidably placed inside the placement groove 4, a positioning block 6 is symmetrically connected to the bottom surface of the side plate 5, one end of the positioning block 6 extends into the positioning groove 7, the positioning groove 7 is symmetrically opened on the bottom surface of the inner side of the placement groove 4, a slot 8 is provided on one end surface of the positioning block 6, one end of the sliding plug 9 is slidably inserted into the slot 8, the other end of the sliding plug 9 is connected through a protrusion 10, the protrusion 10 is symmetrically connected to both ends of the inner surface of the sliding groove 11, the sliding groove 11 is opened on one side surface of the mounting frame 3, a stand 14 is connected to the top surface of the testing host body 1, a through sliding groove 22 is provided on the top surface of the stand 14, and a transparent protective plate 21 is slidably connected inside the sliding groove 22.

[0023] Preferably, the protrusion 10 is provided with a spring 12 that is penetrated by the sliding insert 9, and the sliding insert 9 forms an elastic structure with the protrusion 10 through the spring 12.

[0024] In practical use, when the sliding plug 9 slides in the protrusion 10, the sliding plug 9 can move elastically in the protrusion 10 through the spring 12. By pinching the two pull blocks 13 in the slide groove 11, the two pull blocks 13 are brought closer to each other in the slide groove 11. In this way, the pull blocks 13 will drive the sliding plug 9 to squeeze the spring 12 in the protrusion 10 during the movement. At this time, one end of the sliding plug 9 can be moved into the mounting frame 3. Then, the side plate 5 is slid into the placement groove 4 on the mounting frame 3. The positioning block 6 at the bottom of the side plate 5 will slide into the positioning groove 7. At this time, the slot 8 on the positioning block 6 will move to the position of the sliding plug 9. Then, the pull block 13 is released, and the spring 12 will push one end of the sliding plug 9 into the slot 8 through elasticity, so that the position of the positioning block 6 is fixed in the positioning groove 7. At this time, the side plate 5 will also be fixed in the placement groove 4 on the mounting frame 3, so that the side plate 5 can shield and protect the inspection groove 2.

[0025] Preferably, the sliding insert 9 passes through one end surface of the protrusion 10 and is connected to the pull block 13, and the pull block 13 is slidably connected to the mounting frame 3 through the slide groove 11.

[0026] In practical use, when the pull block 13 slides in the slide groove 11, the pull block 13 will move along with the sliding insert 9 in the protrusion 10.

[0027] Preferably, the inner surface of the support frame 14 is symmetrically provided with movable grooves 15, and the two ends of the movable groove 15 are connected to bearings 16. A screw 17 is connected between the two bearings 16, and one end of the screw 17 extends into the support frame 14 and is fixedly connected to the bearing 16 at the output end of the motor 18.

[0028] In practical use, by starting the motor 18, the output end of the motor 18 can drive the screw 17 to rotate in the bearing 16. At this time, the moving block 19 on the screw 17 will move up and down on the stand 14 along the movable groove 15.

[0029] Preferably, a movable block 19 is threadedly connected to one end of the screw 17. A connecting groove 20 is provided on one side surface of the movable block 19. A transparent protective plate 21 is slidably connected inside the connecting groove 20. Bolts 23 are symmetrically connected to the front surface of the movable block 19. A limiting hole 24 is connected to one end of the bolt 23. The limiting hole 24 is opened through the front surface of the bottom end of the transparent protective plate 21. The bolt 23 is threadedly connected to the fixing hole 25 through the limiting hole 24. The fixing hole 25 is opened inside the rear surface of the connecting groove 20.

[0030] In practical use, when the moving block 19 moves to the bottom of the movable groove 15 and can no longer move, the transparent protective plate 21 is slid through the sliding groove 22 on the stand 14. At this time, one end of the transparent protective plate 21 will pass through the connecting groove 20 on the moving block 19. When the bottom surface of the transparent protective plate 21 contacts the top surface at the bottom of the detection host body 1, the limiting hole 24 on the transparent protective plate 21 will coincide with the position of the fixing hole 25 in the connecting groove 20. At this time, the bolt 23 is passed through the moving block 19 and the limiting hole 24 and then screwed into the fixing hole 25. At this time, the moving block 19 can be connected with the transparent protective plate 21, so that the moving block 19 can move together with the transparent protective plate 21. When the bolt 23 is unscrewed, the transparent protective plate 21 can be separated from the moving block 19, so that the transparent protective plate 21 can be disassembled for maintenance. The transparent protective plate 21 is made of transparent engineering plastic.

[0031] It should be noted that the main testing unit 1 is a TH-8100A tensile testing machine. The motor 18 is electrically connected to an external power source through a control switch. The control switch can be set on one side surface of the stand 14. The motors 18 are symmetrically connected to the top surface of the stand 14. The two motors 18 are connected in parallel to one control switch. In this way, the control switch can control the two motors 18 at the same time, ensuring the synchronicity of the two motors 18 during operation.

[0032] Working principle: When using this strength testing device for cable sheath materials, firstly, according to relevant standards, cut samples of appropriate size and shape from the cable sheath material. Then, record the initial length, width, and thickness of the cable sheath material samples. Next, start the motor 18 via the control switch, causing the output end of the motor 18 to drive the screw 17 to rotate within the bearing 16. At this time, the moving block 19 on the screw 17 will move along the movable groove 15 on the stand 14, allowing the moving block 19 to drive the transparent protective plate 21 to slide in the sliding groove 22 on the stand 14, so that the transparent protective plate 21 can move to the upper position on the stand 14. The clamps in the main body 1 of the testing unit are then exposed. The cable sheath sample is then clamped and fixed between the clamps, ensuring that the axis of the sample coincides with the tensile axis of the main body 1. At this point, the output end of the motor 18 can be controlled to rotate in the opposite direction, causing the moving block 19 to move the transparent protective plate 21 downwards, so that the bottom surface of the transparent protective plate 21 can contact the top surface of the bottom end of the main body 1. At this point, the transparent protective plate 21 can block the front end of the testing position. Then, the test speed, tensile distance, and other parameters are set through the control panel on the main body 1. The main body 1 is then started. Tensile force is applied to the sample according to the set test speed, and force and displacement data are collected in real time by force and displacement sensors. After the test, the tensile strength of the cable sheath material sample can be detected by analyzing and processing the obtained data. When debris splashes towards the operator during the testing of the cable sheath material sample, the transparent protective plate 21 can block the debris, preventing it from splashing onto the operator and causing injury, thereby improving the safety of the strength testing device. When the operator needs to maintain the components in the main body 1 of the testing unit through the maintenance slot 2, he only needs to pinch the slide chute with his hand. The two pull blocks 13 in 11 bring them closer together in the slide groove 11. As the pull blocks 13 move, they drive the sliding insert 9 to press the spring 12 in the protrusion 10. At this time, one end of the sliding insert 9 can be separated from the slot 8 on the positioning block 6. The positioning block 6 can then slide out of the positioning groove 7, allowing the operator to slide the side plate 5 out of the placement groove 4 on the mounting frame 3 without tools. This exposes the inspection groove 2 for maintenance operations, avoiding the need for tools to disassemble the side plate 5, thus saving operation time and facilitating the maintenance of the strength testing device.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
