Description

Technical Field

[0001] The utility model relates to the technical field of cable ties, in particular to a fir-tree-shaped cable tie which is easy to install. Background Art

[0002] Cable ties, also known as cable ties, cable ties, or locking ties, are used for bundling things. Some cable ties have a lock, allowing them to tighten as they go, while others are removable. Cable ties come in metal (usually stainless steel) and plastic (usually nylon) varieties. They are commonly used for cables in electromechanical products, as well as wiring harnesses for computers, electronics, and automobiles.

[0003] When currently used to bundle automotive wiring, cable ties are typically passed around the vehicle's wiring harnesses and frame, then inserted into the locking hole of the strap head. The strap is then tightened with the locking teeth on the strap head, securing the wiring harnesses to the frame. Because vehicles often move at high speeds, the cable ties used to bundle the wiring harnesses can vibrate with the vehicle's high speeds. Friction between the strap and the edge of the frame can easily cause the tie to wear or even break. Furthermore, the pull-out strength of current cable ties is insufficient to meet operational requirements. Vibration can cause the strap's retaining teeth to dislodge, making the tie easily loose, which in turn can cause the wiring harnesses to become loose, posing a safety hazard. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0005] Specifically, the technical problem to be solved by the present invention is to provide a fir-tree-shaped cable tie that is easy to install, so as to solve the technical problem that the current cable tie structure is not convenient for effectively bundling the pipe harness and the pull-out force is difficult to meet the use requirements.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] A fir-tree-shaped cable tie that is easy to install, comprising a cable tie body and a fir-tree head, wherein the cable tie body comprises an integrally formed cable tie head and a cable tie tail, wherein the fir-tree head is located at an end of the cable tie head that is away from the cable tie tail, and the fir-tree head and the cable tie head are integrally formed;

[0008] The belt head has a positioning locking hole for the belt tail to pass through, and the inner wall of the positioning locking hole is provided with a locking tongue integrally formed with the belt head. The locking tongue is located at one end of the belt head close to the fir tree head and is inclined. A deformation groove is provided at the root of the locking tongue, and the end of the locking tongue has at least two locking teeth. The belt tail is evenly provided with a number of ratchet teeth along its length, and the spacing between adjacent locking teeth is adapted to the spacing between adjacent ratchet teeth.

[0009] As an improved technical solution, there are two locking teeth, and the locking teeth include a first locking tooth and a second locking tooth. Define the distance between the first locking tooth and the inner wall of the end of the tape head close to the tape tail as h1, and define the distance between the second locking tooth and the inner wall of the end of the tape head close to the tape tail as h2. h1 and h2 satisfy: h1>h2.

[0010] As an improved technical solution, the deformation groove is located on the side of the insertion end of the lock tongue facing the tape head.

[0011] As an improved technical solution, guide edges are provided on both inner walls of the tape head, and a guide channel is formed between the two corresponding guide edges.

[0012] As an improved technical solution, the guide channel includes a guide section and a positioning section. The lock tongue corresponds to the positioning section, and the end of the lock tongue extends to the positioning section.

[0013] As an improved technical solution, reinforcing edges are provided on both sides of the tape tail, and an insertion guide portion is provided at the end of the tape tail.

[0014] As an improved technical solution, the fir tree head includes an integrally formed guide support disk, a fixing disk and an abutting disk. The fixing disk is located between the guide support disk and the abutting disk, and the abutting disk is a canopy-like structure extending in the direction of the fixing disk relative to the tape head.

[0015] After adopting the above technical solution, the beneficial effects of the present utility model are:

[0016] For this easy-to-install fir tree-shaped cable tie, during use, after bundling the wire harness through the tape body, just press the fir tree head into the sheet metal hole of the sheet metal part. The use operation is simple and convenient. And after the fir tree head is assembled in place with the sheet metal hole of the sheet metal part, the fir tree head will not come out, thus ensuring the firm fixation of the wire harness on the sheet metal part. The deformation groove provided on the lock tongue and the locking teeth can effectively prevent the tape tail from coming out of the positioning lock hole of the tape head. And under the action of the pulling force, the lock tongue will deform, ensuring that the lock tongue is not easily broken. At the same time, each locking tooth is stuck on the corresponding ratchet tooth of the tape tail, which can effectively prevent the tape tail from coming out, thereby realizing the firm bundling of the wire harness and not being easily loosened.

[0031] like Figures 1 to 5 As shown together, this embodiment provides a fir-tree-shaped cable tie that is easy to install, including a strap body 1 and a fir-tree head 2. The strap body 1 is used to bundle the wire harness, and the fir-tree head 2 is used to achieve assembly connection with the sheet metal part. The belt body 1 includes an integrally formed belt head 11 and a belt tail 12, the fir tree head 2 is located at the end of the belt head 11 away from the belt tail 12, and the fir tree head 2 and the belt head 11 are integrally formed; the belt head 11 has a positioning locking hole 111 for the belt tail 12 to pass through, and the inner wall of the positioning locking hole 111 is provided with a locking tongue 112 integrally formed with the belt head 11, the locking tongue 112 is located at one end of the belt head 11 close to the fir tree head 2 and is arranged obliquely, and a deformation groove 1121 is opened at the root of the locking tongue 112, and the end of the locking tongue 112 has at least two locking teeth 1122, and the belt tail 12 is evenly provided with a plurality of ratchet teeth 121 along its length direction. The spacing of adjacent locking teeth 1122 is adapted to the spacing of adjacent ratchet teeth 121 to ensure that after the belt tail 12 is inserted into the positioning locking hole 111 of the belt head 11, each locking tooth 1122 can be stuck in the corresponding ratchet tooth 121, thereby realizing one-way locking of the belt tail 12.

[0032] like Figure 3 and Figure 4 As shown, in this embodiment, there are two locking teeth 1122, and the locking teeth 1122 include a first locking tooth 11221 and a second locking tooth 11222. The distance between the first locking tooth 11221 and the inner wall of one end of the belt head 11 close to the belt tail 12 is defined as h1, and the distance between the second locking tooth 11222 and the inner wall of one end of the belt head 11 close to the belt tail 12 is defined as h2. h1 and h2 satisfy: h1>h2. The first locking tooth 11221 and the second locking tooth 11222 have different heights. When the belt tail 12 is subjected to a pulling force, the lock tongue 112 will swing slightly along the position of the deformation groove 1121, so that the first locking tooth 11221 and the second locking tooth 11222 can be just stuck to the corresponding ratchet tooth 121. That is, when subjected to a pulling force, the heights of the first locking tooth 11221 and the second locking tooth 11222 will remain roughly consistent, achieving effective engagement with the corresponding ratchet tooth 121, increasing the pulling force of the belt body 1, and ensuring that the belt tail 12 will not fall out of the positioning locking hole 111 of the belt head 11.

[0033] Optionally, the number of locking teeth 1122 can also be three, four, five, etc.

[0034] As Figure 3 and Figure 4 shown, in this embodiment, the deformation groove 1121 is located on the side of the locking tongue 112 towards the insertion end of the leading head 11. Thus, when the locking tongue 112 is subjected to a pulling force, its locking teeth 1122 swing and deform in the direction close to the trailing end 12, ensuring effective engagement between the locking teeth 1122 and the ratchet teeth 121 and preventing the trailing end 12 from disengaging.

[0035] As Figures 3 to 5 collectively shown, in this embodiment, guiding edges 114 are provided on the inner walls on both sides of the leading head 11, and a guiding channel 113 is formed between the two corresponding guiding edges 114. The formed guiding channel 113 can guide the trailing end 12 when the trailing end 12 is inserted, enabling the trailing end 12 to be quickly and accurately inserted into the positioning and locking hole 111 of the leading head 11.

[0036] As Figures 3 to 5 collectively shown, in this embodiment, the guiding channel 113 includes a guiding section 1131 and a positioning section 1132. The guiding section 1131 guides the trailing end 12 during insertion. The locking tongue 112 corresponds to the positioning section 1132, and the end of the locking tongue 112 extends into the positioning section 1132 to lock the trailing end 12 in the positioning section 1132, preventing the trailing end 12 from disengaging.

[0037] As Figure 1 shown, in this embodiment, reinforcing edges 122 are provided on both sides of the trailing end 12, which can effectively increase the structural strength of the trailing end 12 and prevent the trailing end 12 from being pulled and broken. An insertion guiding portion 123 is provided at the end of the trailing end 12 to guide the trailing end 12 during insertion into the positioning and locking hole 111 of the leading head 11, enabling the trailing end 12 to be more quickly and accurately inserted into the positioning and locking hole 111 of the leading head 11.

[0038] As Figures 1 to 3 、 Figure 5 collectively shown, in this embodiment, the fir tree head 2 includes an integrally formed guiding and supporting disk 21, a fixing disk 22, and an abutting disk 23. The fixing disk 22 is located between the guiding and supporting disk 21 and the abutting disk 23. The abutting disk 23 is an umbrella-shaped structure extending in the direction towards the fixing disk 22 relative to the leading head 11. The guiding and supporting disk 21 plays a role in guiding and supporting during the assembly with the sheet metal hole of the sheet metal part. The fixing disk 22 is adapted to the sheet metal hole of the sheet metal part, which is a guarantee for the firm cooperation between the fir tree head 2 and the sheet metal part and plays a locking role after being assembled with the sheet metal part. After the fir tree head 2 is assembled with the sheet metal part, the abutting disk 23 can abut against the sheet metal part, playing a role in dust prevention and protection, and at the same time having a pre-tightening force to prevent the cable tie from shaking.

[0039] In this embodiment, the belt body 1 and the fir tree head 2 are of an integrally formed structure injection-molded by a horizontal injection molding machine, with high structural strength and low manufacturing cost.

[0040] Based on the above structure of the conveniently installable fir tree-shaped cable tie, during use, after bundling the wire harness through the belt body 1, just press the fir tree head 2 into the sheet metal hole of the sheet metal part directly. The use operation is simple and convenient. Moreover, after the fir tree head 2 is assembled in place with the sheet metal hole of the sheet metal part, the fir tree head 2 will not come out, thus ensuring the firm fixation of the wire harness on the sheet metal part. The deformation groove 1121 formed in the locking tongue 112 and the locking teeth 1122 it has can effectively prevent the belt tail 12 from coming out of the positioning and locking hole 111 of the belt head 11. And under the action of the pulling force, the locking tongue 112 will deform, ensuring that the locking tongue 112 is not easily broken. At the same time, each locking tooth 1122 is stuck to the corresponding ratchet tooth 121 of the belt tail 12, which can effectively prevent the belt tail 12 from coming out, thus realizing the firm bundling of the wire harness and not being easily loosened.

[0041] It should be understood that the use of these embodiments is only for illustrating the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
