Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable tie technology, and in particular to a cable tie with a built-in cutting function. Background Technology
[0002] Disposable cable ties are widely used in electronic equipment assembly, cable bundling, and packaging due to their ease of use and low cost. To address the issue of needing additional tools to cut off excess portions after tightening traditional cable ties, existing technologies have developed disposable cable ties with built-in cutting blades. The blade is integrated inside the locking head, and the excess portion is cut by twisting the cable tie. However, since the blade position is fixed, if the twisting angle of the cable tie is off or the contact pressure is insufficient, incomplete cutting may occur, requiring repeated twisting. Furthermore, after cutting, the end face of the cable tie may protrude due to the excessive distance between the blade and the inner wall of the locking head, forming sharp burrs that could scratch operators or surrounding equipment. Utility Model Content
[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0004] In view of the problems existing in the above and / or existing cable ties with built-in cutting function, this utility model is proposed.
[0005] Therefore, the problem to be solved by this utility model is that the cutting reliability of disposable cable ties with built-in cutting blades is insufficient due to the fixed position of the blade, and the cutting end face of the cable tie is prone to protrusion, which poses a safety hazard.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cable tie with a built-in cutting function, comprising a main body component including a locking head, wherein a cable tie is fixed inside the locking head, and a fixing block is fixed inside the locking head;
[0007] A cutting assembly, disposed within the latch head, includes a cutting component. The cutting component includes a fixing seat fixed within the latch head. A lifting groove is provided within the fixing seat. A cutting head is slidably disposed within the lifting groove. A first elastic piece is fixed to one end of the cutting head, and the other end of the first elastic piece is fixed to the inner wall of the lifting groove.
[0008] As a preferred embodiment of the cable tie with built-in cutting function of this utility model, the cutting component further includes a trigger member located in the fixed base. The trigger member includes a trigger block located on one side of the cutter head. A moving groove is provided in the fixed base. The trigger block slides in the moving groove.

[0013] As a preferred embodiment of the cable tie with built-in cutting function described in this utility model, there are two trigger blocks, which are symmetrically distributed on both sides of the cutter head.
[0014] As a preferred embodiment of the cable tie with built-in cutting function described in this utility model, wherein: a connecting rod is fixed on the trigger block, and the connecting rod is U-shaped.
[0015] As a preferred embodiment of the cable tie with built-in cutting function described in this utility model, there are two locking blocks, which are symmetrically distributed on both sides of the cutter head.
[0016] As a preferred embodiment of the cable tie with built-in cutting function described in this utility model, the cable tie has a groove and the fixing block has a protrusion.
[0017] The beneficial effects of this utility model are as follows: by designing the blade to be movable, the blade can unlock and move upward when the cable tie is twisted, automatically approaching the part of the cable tie to be cut, ensuring stable contact pressure.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example 1
[0029] Reference Figures 1-5This is the first embodiment of the present invention. This embodiment provides a cable tie with a built-in cutting function. The cable tie with a built-in cutting function includes a main component 1, including a locking head 11. A cable tie 12 is fixed inside the locking head 11. The cable tie 12 can be bent. A fixing block 13 is fixed inside the locking head 11. When binding, one end of the cable tie 12 is inserted into the gap formed between the inner wall of the locking head 11 and the top of the fixing block 13. Then, the cable tie 12 is pulled to complete the binding. This is the prior art. This solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.
[0030] The cutting component 2 is located inside the locking head 11 and includes a cutting element 21. The cutting element 21 is used to cut the excess cable ties 12 after the binding is completed.
[0031] The cutting component 21 includes a fixed base 211 fixed inside the locking head 11. A lifting groove 211-1 is provided inside the fixed base 211. A cutting head 212 is slidably arranged inside the lifting groove 211-1. A first elastic piece 213 is fixed to one end of the cutting head 212, and the other end of the first elastic piece 213 is fixed to the inner wall of the lifting groove 211-1. During assembly, the first elastic piece 213 is in a compressed state, thereby continuously applying an upward pushing force to the cutting head 212. In the initial state, the cutting head 212 is at its lowest position, which does not affect the cable tie 12 from completing the binding operation. When it is necessary to cut the cable tie 12, the cutting head 212 will move upward under the push of the first elastic piece 213, thereby completing the cutting of the cable tie 12. The first elastic piece 213 has a large elasticity.
[0032] Example 2
[0033] Reference Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0034] Specifically, the cutting assembly 2 also includes a trigger 22 located in the fixing base 211. The trigger 22 is configured such that the cutter head 212 will only move upward to perform cutting when the cable tie 12 is twisted.
[0035] The trigger element 22 includes a trigger block 221 located on one side of the cutter head 212. A moving groove 211-2 is provided in the fixed base 211. The trigger block 221 slides in the moving groove 211-2 and can rise and fall in the moving groove 211-2. A second elastic sheet 222 is fixed on one side of the trigger block 221, and the other end of the second elastic sheet 222 is fixed on the second elastic sheet 222. The second elastic sheet 222 is used to apply a pushing force to the trigger block 221 to ensure that the top of the trigger block 221 protrudes from the upper surface of the fixed base 211 without the action of other external forces.
[0036] When the cable tie 12 is twisted, the cable tie 12 will squeeze the trigger block 221, the second elastic sheet 222 will be squeezed, and the trigger block 221 will move downward along the moving groove 211-2 to complete the triggering.
[0037] Specifically, the fixing base 211 has a rectangular groove 211-3, and a third elastic piece 223 is fixed on the inner wall of the rectangular groove 211-3. A locking block 224 is fixed on the third elastic piece 223. Without any other external force, the third elastic piece 223 applies a pushing force to the locking block 224, so that the locking block 224 is located close to the cutter head 212. The cutter head 212 has a first locking groove 212-1. In the initial state, the first elastic piece 213 is in a compressed state, and the locking block 224 engages with the first locking groove 212-1. Under the combined action of the two, the position of the cutter head 212 will be restricted, so as to prevent the cutter head 212 from affecting the normal binding operation of the cable tie 12.
[0038] Specifically, a pressing rod 225 is fixed at the bottom of the trigger block 221. One end of the pressing rod 225 is inclined, and the lower part of the pressing rod 225 is located on one side of the third elastic sheet 223. In the initial state, the third elastic sheet 223 has a certain tilt angle, and at this time the pressing rod 225 is in contact with the third elastic sheet 223.
[0039] When the trigger block 221 moves downward along the moving groove 211-2, it will synchronously drive the pressing rod 225 to move downward. The pressing rod 225 presses the third elastic plate 223, causing the third elastic plate 223 to rotate, thereby driving the locking block 224 to move away from the first locking groove 212-1, thus releasing the limit of the cutter head 212. Then, under the action of the first elastic plate 213, the cutter head 212 is pushed upward. As the cable tie 12 continues to twist, when the cable tie 12 separates from the trigger block 221, the second elastic plate 222 will drive the trigger block 221 to reset, so that the pressing rod 225 no longer presses the third elastic plate 223. The third elastic plate 223 resets and causes the locking block 224 to move towards the position of the cutter head 212.
[0040] Specifically, the fixed base 211 has a through groove corresponding to the extrusion rod 225 and is connected to the rectangular groove 211-3.
[0041] Example 3
[0042] Reference Figures 4-6 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0043] Specifically, the cutter head 212 is also provided with a second locking groove 212-2. The locking block 224 can engage with the second locking groove 212-2. As the cutter head 212 moves upward, the second locking groove 212-2 will also move upward. After the third elastic piece 223 resets and the locking block 224 moves towards the position of the cutter head 212, when the second locking groove 212-2 moves to the coaxial position with the locking block 224, the second locking groove 212-2 and the locking block 224 will engage again. At this time, the position of the cutter head 212 will be restricted, so that the cutter head 212 is kept in the upper position. As the cable tie 12 is further twisted, it can be ensured that the cutter head 212 can smoothly cut the cable tie 12.
[0044] After the cable tie is cut, the distance between the cutter head 212 and the inner wall of the locking head 11 is very small after the cutter head 212 moves upward. The cut cable tie end face will be restricted between the cutter head 212 and the locking head 11 to avoid protrusion and burr formation, and reduce the risk of scratches.
[0045] Specifically, there are two trigger blocks 221, which are symmetrically distributed on both sides of the cutter head 212.
[0046] The distance between the two trigger blocks 221 is slightly greater than the width of the cable tie 12. As the cable tie 12 twists at a certain angle, the cable tie 12 may no longer be in contact with the trigger block 221. At this time, the trigger block 221 can be reset.
[0047] Specifically, a connecting rod 226 is fixed on the trigger block 221. The connecting rod 226 is U-shaped and is used to connect the two trigger blocks 221. Regardless of the twisting direction of the cable tie 12, when twisting, one trigger block 221 can move downward, thereby driving the other trigger block 221 to move downward synchronously.
[0048] Specifically, there are two locking blocks 224, symmetrically distributed on both sides of the cutter head 212. When the two trigger blocks 221 move downward, the two locking blocks 224 can be separated from the corresponding first locking groove 212-1 at the same time, thereby releasing the limit of the cutter head 212.
[0049] Specifically, the cable tie 12 has a groove 12-1 and the fixing block 13 has a protrusion 13-1. The groove 12-1 and the protrusion 13-1 correspond to each other. Through the cooperation of the two, the cable tie 12 can only move in one direction in the gap formed between the inner wall of the locking head 11 and the top of the fixing block 13, which facilitates the binding of objects. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.
[0050] In use, insert one end of the cable tie 12 into the gap formed between the inner wall of the locking head 11 and the top of the fixing block 13, then pull the cable tie 12 to complete the binding. Then twist the cable tie 12, which will squeeze the trigger block 221. The second elastic piece 222 is squeezed, and the trigger block 221 moves downward along the moving groove 211-2, which simultaneously drives the squeezing rod 225 to move downward. The squeezing rod 225 squeezes the third elastic piece 223, causing the third elastic piece 223 to rotate, thereby driving the locking block 224 to move away from the first locking groove 212-1, thereby releasing the limit of the cutter head 212. Then, under the action of the first elastic piece 213, the cutter head 212 is pushed upward.
[0051] When the cable tie 12 separates from the trigger block 221, the second elastic piece 222 will drive the trigger block 221 to reset, so that the compression rod 225 will no longer compress the third elastic piece 223. The third elastic piece 223 resets and causes the locking block 224 to move toward the position of the cutter head 212. As the cutter head 212 moves upward, the second locking groove 212-2 moves to a position coaxial with the locking block 224. The second locking groove 212-2 and the locking block 224 will engage again. At this time, the position of the cutter head 212 will be restricted, so that the cutter head 212 is kept in the upper position. As the cable tie 12 twists further, it can be ensured that the cutter head 212 can cut the cable tie 12 smoothly.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
