[0002] Nylon cable ties, also known as cable ties or drawstrings, are a type of tying tool made of nylon. They are generally tough and durable, making them a convenient tool for quickly tying various items. One end of a nylon cable tie has a small gear that inserts into the other end of the tie to form a loop. The gear allows for secure binding without loosening, ensuring a secure fit.
[0003] Nylon cable ties are often used to bind important items and equipment, such as wires, pipes, and building materials. If they break under heavy loads, they can cause equipment damage, safety incidents, and even personal injury. Tensile strength testing ensures cable ties are safe to use under the expected load conditions.
[0004] However, when the existing nylon cable tie tensile strength testing device is used, both sides of the cable tie are simultaneously compressed, and then the cable tie is pulled to perform a tensile strength test on the cable tie. However, when the cable tie is clamped, since the cable tie is placed horizontally and has a slender shape, the cable tie is easily detached from the testing device when pulled, which is not conducive to testing. Therefore, a nylon cable tie tensile strength testing device is proposed to solve the above problem. Utility Model Content

[0030] The following will be combined with the drawings in the specification of this utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility model.
[0031] Reference Figure 1 、 Figure 3 and Figure 4, An embodiment provided by the present utility model: A nylon tie tensile strength detection device, including a base 1, supports 2 are arranged on both sides of the top surface of the base 1, bases 3 are fixedly connected to the near sides of the top surfaces of the two supports 2, a tensiometer is arranged outside the base 3, brackets 4 are fixedly connected to the middle parts of the top surfaces of the two supports 2, threaded rods 5 are threadedly connected to the middle parts of the two brackets 4, the bottoms of the two threaded rods 5 are rotatably connected to pressing plates 6, the bottom surface of the pressing plate 6 contacts the top surface of the base 3, pressing blocks 9 are fixedly connected to the middle parts of the bottom surfaces of the two pressing plates 6, inclined rods 7 are rotatably connected to the far sides of the bottom surfaces of the two pressing plates 6, clamping blocks 8 are rotatably connected to the bottoms of the two inclined rods 7, the near sides of the two clamping blocks 8 respectively contact the far sides of the two bases 3, and a power mechanism for driving the support 2 to move is installed on one side of the base 1.
[0032] When in use, first use the power mechanism to drive the two supports 2 to approach, then place the tie on the support 2, and make a part of both ends of the tie expose from the top surfaces of the two bases 3. Then rotate the threaded connection to push out the pressing plate 6 to make it approach the base 3 to clamp the tie. At this time, the pressing block 9 will first approach the tie and press the tie to make it bend. At the same time, the pressing plate 6 will also squeeze the inclined rod 7 to make the clamping block 8 approach the base 3. At this time, the bending and clamping of the tie can be completed, and it is distributed in an inverted U shape on the top surfaces of the two bases 3. Therefore, when pulling, the bent part of the tie will closely adhere to the side wall of the base 3, and this part and the stress curve of the tie when being pulled are in a perpendicular state. Therefore, the fixing effect of the tie can be improved, and the phenomenon that the tie falls off due to its too thin diameter and affects the tensile strength test can be avoided.
[0033] Refer to Figure 1 、 Figure 2 and Figure 3 , The power mechanism includes a motor 10, the output end of the motor 10 is fixedly connected to a bidirectional screw 11, the bidirectional screw 11 is rotatably connected to the middle of the top surface of the base 1, and the two supports 2 are respectively threadedly connected to both sides of the outer wall of the bidirectional screw 11. Guide blocks 12 are fixedly connected to the bottoms of the outer walls of the two supports 2, cavities are opened on both sides of the inner wall of the base 1, and the two guide blocks 12 are respectively slidably connected in the two cavities.
[0034] By driving the motor 10, the bidirectional screw 11 can be rotated, and the bidirectional screw 11 can drive the two supports 2 to approach or move away from each other. Therefore, the distance between the two bases 3 can be adjusted, so that ties of different lengths can be tested, improving the adaptability of the device. At the same time, when the two supports 2 approach or move away from each other, the guide block 12 will slide inside the base 1 at this time. Therefore, the movement direction of the support 2 can be guided, and the stability of the operation of this device can be improved.
[0035] Refer to Figure 1 、 Figure 3 and Figure 4 The distal sides of the top surfaces of both support members 2 are fixedly connected to side plates 13, and the distal sides of the pressure plates 6 on both sides are slidably connected to the proximal sides of the side plates 13. A guide rod 14 is fixedly connected to the bottom of one side of the side plates 13. A through hole 1 is defined in the middle of the clamping block 8, and guide rod 14 is located within through hole 1. A guide rod 2 is fixedly connected to the top surface of the support member 2, and a through hole 2 is defined in the middle of the pressure plate 6, and guide rod 2 15 is located within through hole 2.
[0036] By rotating the threaded rod 5, the pressure plate 6 can be pushed out, and at this time the outer wall of the pressure plate 6 will contact the side plate 13, and the pressure plate 6 will also slide up and down along the second guide rod 15, thereby improving the stability of the pressure plate 6 during displacement. At the same time, when the pressure plate 6 squeezes the inclined rod 7 and drives the clamping block 8 close to the base 3, the first guide rod 14 can guide the movement direction of the clamping block 8.
[0037] Reference Figure 1 and Figure 3 The outer walls of the bases 3 on both sides are fixedly connected with a support frame 16, and the dynamometer is located in the support frame 16. The top surfaces of the bases 3 on both sides are provided with a plurality of grooves 17, and nylon cable ties are placed in the grooves 17.
[0038] After the cable tie is placed, the force gauge is taken out and the two sides of the force gauge are hooked on the support frame 16. The force gauge can now be installed. After the force gauge is placed, the two supports 2 are moved away from each other to pull the cable tie. At this time, the force gauge and the cable tie will be pulled at the same time, and the tension reading can be displayed by the force gauge. Therefore, when the cable tie breaks, the force gauge reading at this time is the tensile strength of the broken cable tie.
[0039] Working principle: When in use, first drive the motor 10 to rotate the bidirectional screw 11. At this time, the bidirectional screw 11 can drive the two side supports 2 to approach or move away from each other, so as to adjust the distance between the two supports 2 to adapt to the length of the tie. After the adjustment is completed, place the tie on the support 2, place multiple or single ties in the groove 17, and make the two sides of the tie respectively expose from the far sides of the two bases 3. Then rotate the threaded rod 5 to push out the pressing plate 6 to make it approach the base 3. When the pressing plate 6 approaches the support 2, in this process, the pressing block 9 will first contact the tie, and the pressing block 9 will press down the part of the tie exceeding the base 3 to bend the tie. As the pressing plate 6 moves down, the pressing plate 6 will also press the tie tightly. When the pressing plate 6 moves down, it will also squeeze the inclined rod 7. At this time, the inclined rod 7 will push the clamping block 8 to slide along the first guide rod 14, so that the clamping block 8 approaches the base 3 to clamp the end of the tie. At this time, the fixing of the tie can be completed. After the pressing plates 6 on both sides press the tie tightly, the tie will be distributed in an inverted U shape on the two bases 3. Then hook the two sides of the tensiometer on the two support frames 16. Finally, drive the motor 10 to rotate the bidirectional screw 11 to make the two side supports 2 move away from each other to pull the tie. When the two supports 2 move away from each other, the tensiometer and the tie will be pulled at the same time, and the tensiometer will display the tensile reading. Therefore, when the tie breaks, the reading of the tensiometer at this time is the tensile strength of the broken tie.
[0040] 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.
