[0002] With the continuous improvement of the intelligent level, the functions of various construction machinery, motor vehicles and other vehicles are becoming more and more abundant. At the same time, there are more and more dense wire harnesses, cables and various pipelines in the limited space of the whole machine. In order to make reasonable use of space, avoid mutual interference between lines, and ensure that each line can operate stably and reliably, the reasonable layout and reliable fixation of dense wire harnesses, cables and various pipelines on the whole vehicle have become an important part to ensure the normal operation of the whole vehicle. In order to realize the reliable fixation of the wire harness, cable and various pipelines of the whole vehicle, it is particularly important to select a suitable and reliable fixing cable tie.

[0003] At present, the commonly used cable tie is a single cable tie. Different wire harnesses need to be fixed by different cable ties respectively, which occupies more space between the limited space and the dense wire harnesses, and also increases the assembly time and material cost of the wire harness.

When the cable tie body passes through the engaging socket, the engaging teeth are engaged with the locking teeth, and the cable tie body is bent and then passes through the engaging socket.

[0008] In combination with the first aspect, in an implementable manner, a deformation groove is further provided between the locking teeth and the outer side surface of the locking portion, so that when the cable tie body penetrates into the engaging socket, the locking teeth are pressed by the engaging teeth and move closer to the locking portion.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Please refer to Figure 1 and Figure 2, the double-headed cable tie provided by the present utility model will now be described. The double-headed cable tie includes a locking head 1 and two cable tie bodies 2 integrally formed on both symmetric sides of the locking head 1; the locking head 1 has a locking body 11 and locking parts 12 symmetrically arranged on both sides of the locking body 11. Locking sockets 121 for the cable tie bodies 2 to pass through are respectively provided on the locking parts 12, locking teeth 123 are arranged in the locking sockets 121, and meshing teeth 21 meshing with the locking teeth 123 are arranged on the cable tie bodies 2; a fixing hole 111 for a fastener 3 to pass through is provided on the locking body 11.

[0025] Compared with the prior art, the beneficial effects of the double-headed cable tie provided by the present utility model are as follows: First, cable tie bodies 2 are respectively arranged on both symmetric sides of the locking head 1. After each cable tie body 2 is respectively inserted into the locking socket 121 on the same side, two bundles of parallelly arranged wire harnesses, cables or pipelines and other pipelines 4 can be bundled at the same time, and the locking head 1 is fixed on the vehicle body through the fastener 3. The two parallel pipelines 4 do not interfere with each other, avoiding the risk of unstable line operation caused by mutual interference between the pipelines 4, and ensuring the stability and reliability of line operation; Second, on the other hand, the two cable tie bodies 2 share one locking head 1, which is equivalent to reducing one locking head 1, thus reducing the space occupied by one locking head 1 and the material cost used, so as to reasonably layout the pipelines 4 in a limited space, avoid the problem of crowded layout between the pipelines 4, and also facilitate the heat dissipation of the pipelines 4; Third, the bundling time of the pipelines 4 is shortened, and the bundling efficiency of the pipelines 4 is improved; Fourth, by using the double-headed cable tie provided in this application, two pipelines 4 can be fixed in the same direction at the same time, and the two pipelines 4 do not contact each other, which also makes the layout of the whole vehicle pipelines 4 more concise and beautiful.

[0026] The double-headed cable tie provided in this application not only basically saves space, reduces costs and improves the assembly efficiency, but also improves the convenience of assembly.

[0027] Since there are technical materials recording double-headed cable ties or two-way cable ties in the current market and prior publicly disclosed materials, but the application of the currently disclosed double-headed cable ties in vehicles such as construction machinery, household cars, and large buses is not common. The reason is that the structure of the existing double-headed cable ties is complex, especially the locking structure of the locking head 1 is relatively complex and not convenient to use. However, the double-headed cable tie provided in this application has a simple structure, is convenient for inserting the cable tie, and is convenient for fixing the cable tie on the installed vehicle body.

[0028] By optimizing the structure of the locking head 1 and the structure of the locking teeth 123, this application can achieve the advantages of simplified structure and convenient assembly of the double-headed cable tie. Multiple technical means are given below for gradual optimization.

[0029] For example, in some embodiments, refer to Figure 3, the locking portion 12 and the buckle body 11 form a rectangular groove, and the buckle body 11 forms the bottom of the rectangular groove. This structure thins the thickness of the buckle body 11 of the buckle head 1, only retaining the thickness of the locking portion 12 where the locking socket 121 is provided. It can simplify the structure, reduce the material usage cost, facilitate miniaturization of the body size and reduce the occupied space. At the same time, it ensures the length of the locking between the tie strap body 2 and the locking socket 121, thus ensuring the reliability of the pipeline 4 after being tied. The tie strap body 2 is connected to one end of the locking portion 12 away from the buckle body 11; a locking socket 121 is formed between the tie strap body 2 and the locking portion 12. Among them, the rectangular groove formed by the buckle head 1 also provides a space for the fixed installation of the fastener 3. Due to the thinning design of the buckle body 11, a shorter fastener 3 can be used to fix the buckle head 1 on the vehicle body, reducing the material cost brought by using a longer fastener 3.

[0030] In this embodiment, the tie strap body 2 is arranged at one end of the locking portion 12 away from the buckle body 11, that is, the tie strap body 2 is arranged at the notch of the rectangular groove. A space for arranging the pipeline 4 is also formed between the tie strap body 2 and the outer side surface of the locking portion 12. After the tie strap body 2 is bent to tie the pipeline 4, its end is simultaneously pressed against the vehicle body tightly by the pipeline 4, forming a certain restriction on the end of the tie strap body 2, and also avoiding the risk of the tie strap body 2 disengaging from the locking socket 121, further improving the reliability of the bundling and fixing of the pipeline 4 and also improving the convenience of the assembly of the double-headed tie strap.

[0031] Based on this structural design, the locking teeth 123 of the present application can be designed to be simpler. After the tie strap body 2 passes through the locking socket 121, it is beneficial for the bending elasticity of the tie strap body 2 to form an elastic abutment with the vehicle body, which can ensure the firmness of the fixation of the pipeline 4. Thus, the simple locking teeth 123 can also facilitate the convenience of the assembly of the tie strap body 2.

[0032] To more clearly describe the technical features and usage methods of the double-headed tie strap provided by the present application, in this embodiment, the direction in which the opening of the rectangular groove faces upward is used as the fixing direction. Then, the locking portion 12 symmetrically forms the left and right side walls of the rectangular groove. A pipeline 4 layout area is formed in the area surrounded by the lower part of the tie strap body 2 and the outside of the locking portion 12. The locking teeth 123 are engaged with the meshing teeth 21, and they have the same tooth shape. Taking the locking teeth 123 as an example, the locking teeth 123 have an abutting inclined surface and a locking plane 125. The shape of the locking teeth 123 is triangular. The abutting inclined surface of the locking teeth 123 abuts against the inclined surface of the meshing teeth 21 in the left-right direction, and the locking plane 125 of the locking teeth 123 abuts against the plane of the meshing teeth 21 in the up-down direction to form locking, forming a mutually engaged locking state. When the tie strap body 2 is to be pulled out from the locking socket 121 in the up-down direction, due to the blocking of the locking plane 125 on the meshing teeth 21, it is very difficult for the tie strap body 2 to be pulled out from the locking socket 121.

[0033] In some embodiments, see Figure 3 The locking teeth 123 are arranged on the outer side surface of the locking portion 12, and the locking teeth 123 are exposed outside the locking socket 121. The shortest distance between the tooth top of the locking teeth 123 and the inner wall of the locking socket 121 on the same side is less than the thickness of the tie body 2; when the tie body 2 passes through the locking socket 121, the meshing teeth 21 mesh with the locking teeth 123, and the tie body 2 is bent and passes through the locking socket 121. When the tie body 2 passes through the locking socket 121, it needs to bend toward the inner wall direction of the locking socket 121 (or toward the fixing hole 111 on the lock body 11) to pass through. At this time, the locking socket 121 also has a tendency to apply force to the tie body 2 toward the inner wall direction of the locking socket 121. When the tie body 2 passes through the locking socket 121, it will have a tendency to reset due to free release, thereby improving the firmness of the bundling.

[0034] In some embodiments, see Figure 2 and Figure 3 A deformation groove 13 is also provided between the locking tooth 123 and the outer side surface of the locking portion 12, so that when the cable tie body 2 is inserted into the locking insertion hole 121, the locking tooth 123 is pressed by the meshing tooth 21 and moves closer to the locking portion 12. The deformation groove 13 extends from top to bottom, and the lower end of the locking tooth 123 is fixed on the locking portion 12, and its upper end is in a free state. The deformation groove 13 provides a deformation space for the locking tooth 123 to be compressed and deformed. The locking tooth 123 is pressed by the meshing tooth 21 and moves closer to the locking portion 12, freeing up more space for the cable tie body 2 to penetrate the locking insertion hole 121, facilitating the smooth binding of the cable tie body 2 and improving the convenience of assembly. The deformation of the locking tooth 123 obtains elastic energy, so that the locking tooth 123 can be tightly meshed with the meshing tooth 21 on the cable tie body 2, ensuring the firmness of the locking.

[0035] The present application only provides one locking tooth, and conventional meshing teeth are provided on the cable tie body. The cable tie has a simple design structure, is easy to manufacture, saves materials, and reduces manufacturing costs.

[0036] Of course, after the pipeline 4 is arranged and fixed, it is inevitable that it will be damaged, repaired, replaced, etc., and it is necessary to pull the cable tie body 2 out of the locking socket 121 without damaging the double-headed cable tie itself and the pipeline 4; in order to solve the problem of cable tie disassembly, the present application also designs a structure to assist in pulling out the cable tie body 2.

[0037] Specifically in the embodiment, see Figure 2 and Figure 3, there is also a limiting part 124 provided on the locking tooth 123. The limiting part 124 is connected to the locking tooth 123 and is located on the side close to the locking socket 121. The height of the limiting part 124 is lower than the tooth height of the locking tooth 123 to avoid the tying belt body 2 penetrating into the locking socket 121. The designed limiting part 124 in this embodiment also ensures the smooth penetration of the tying belt body 2 through the locking socket 121 first. Therefore, the height of the limiting part 124 needs to be lower than the tooth height of the locking tooth 123 to form a more sufficient avoidance space for the tying belt body 2 to pass through. Another purpose of the limiting part 124 is to assist the extraction of the end of the tying belt body 2 from the locking socket 121. Since the limiting part 124 is provided on the locking tooth 123, there is also a deformation groove 13 between the limiting part 124 and the locking part 12. When it is necessary to extract the tying belt body 2 from the locking socket 121, the limiting part 124 can be toggled towards the locking part 12 by hand or a tool, thereby expanding the avoidance space for the tying belt body 2 to pass through and making the plane of the engaging tooth 21 misaligned with the locking plane 125 of the locking tooth 123, and then the tying belt body 2 can be extracted from the locking socket 121.

[0038] As can be seen from the above embodiments, the structure of the locking tooth 123 of the present application is simple. Only conventional engaging teeth 21 need to be made on the tying belt body 2, and the assembly and disassembly are also convenient.

[0039] In some embodiments, referring to Figure 1 and Figure 3 , there is also an avoidance groove 122 provided on the outer side surface of the locking part 12, and the locking tooth 123 is arranged in the avoidance groove 122. Specifically, an avoidance groove 122 with an upper end opening is provided on the outer side surface of the locking part 12 from top to bottom. The tying belt body 2 is connected to the upper end opening of the avoidance groove 122 to form an enclosure, constituting the locking socket 121. The area of the avoidance groove 122 below the tying belt body 2 is exposed outside the locking part 12, and also makes the locking tooth 123 and the limiting part 124 exposed outside the locking socket 121, facilitating toggling and deformation to realize the insertion and extraction of the tying belt body 2.

[0040] Due to the avoidance groove 122 provided on the outer side surface of the locking part 12, a stepped surface is also formed on the outer side surface of the locking part 12. The lower end of the locking tooth 123 is integrally formed on this stepped surface, and the deformation groove 13 is formed between the locking tooth 123 and the avoidance groove 122.

[0041] In some embodiments, referring to Figure 3 , the tooth top of the locking tooth 123 does not protrude from the outer side surface of the locking part 12. That is, when the locking tooth 123 is in a free state, the locking tooth 123 is completely within the avoidance groove 122. This design can ensure firm fixation of the tying belt body 2 while being relatively easy to manufacture.

[0042] In some embodiments, the buckle body 11 has a support plane that fits onto the installation plane, which is used to enhance the fixing firmness of the double-headed cable tie. Through the designed surface-to-surface contact, the contact area between the double-headed cable tie and the vehicle body is increased, thereby enhancing the fixing firmness of the cable tie.

[0043] Regarding the fixing of the double-headed cable tie, the fastener 3 can be a bolt, a screw, or a buckle; and the fastener 3 can be movable or integrally formed on the vehicle body sheet metal; meanwhile, the fixing hole 111 is provided at the central position of the buckle body 11.

[0044] In the above embodiments, the descriptions of each embodiment have their own focuses. For the parts not detailed or recorded in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0045] Based on the same inventive concept, the embodiments of the present application further provide a vehicle provided with the double-headed cable tie. Specifically, first, according to the preset pipeline 4 route, thread holes are made on the vehicle body, and then the double-headed cable tie is fixed to the vehicle body through bolts that fit the thread holes to gather the pipeline 4 below the cable tie body 2. Then, the cable tie body 2 is bent around the pipeline 4 and passes through the locking socket 121, so as to achieve the simultaneous fixing of two parallel pipelines 4 in the same space and the same direction, as shown in Figure 4 shown.

[0046] For the vehicle provided by the present utility model, since this double-headed cable tie is used to fix the pipelines 4 in parallel, the occupied space is reduced, the rationality and reliability of the pipeline 4 layout are improved, and the time and material costs for arranging the pipelines 4 are also reduced, thereby facilitating the improvement of the overall vehicle production efficiency and the reduction of the manufacturing cost.

[0047] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
