Obviously, the described embodiments 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 creative work are within the scope of protection of the utility model.

[0025] Ginseng Figures 1 to 5 As shown, a snap-on cable tie comprises a lock buckle 1, a sleeve 2 and a cable tie 3 which are arranged in sequence. A slot 11 is provided in the lock buckle 1, a latch tongue 12 is provided in the slot 11, the cable tie 3 is a strip structure, and saw teeth 31 corresponding to the latch tongue 12 are provided in its side surface, and the sleeve 2 is a hollow columnar structure, and a plurality of spring tongues 21 are provided on the inner wall of the end thereof away from the cable tie 3.

[0026] In this technical solution, the screw is screwed into the ferrule from the end where the spring tongue is located to avoid interference with the use of cable ties and locks. The length of the ferrule is greater than the corresponding length of the spring tongue to ensure full contact between the screw and the spring tongue, while avoiding interference with the screw protruding from the ferrule and avoiding damage to the wiring harness. Multiple spring tongues are arranged in the ferrule, which can adapt to screws of multiple specifications at the same time, thereby improving the compatibility of the product.

[0027] For example, see Figure 2 As shown, a plurality of spring tongues 21 are arranged at intervals along the inner wall of the ferrule 2 in the circumferential direction.

[0028] In this technical solution, adjacent spring tongues do not interfere with each other, and the spring tongues act on the screws from multiple circumferential angles at the same time, thereby improving the bonding strength between the screws and the spring tongues, thereby ensuring the overall fixing strength of the cable tie.

[0029] For example, see Figures 3 to 5 As shown, adjacent spring tongues 21 are staggered along the axial direction of the ferrule 2 .

[0030] In this technical solution, the spring tongues are staggered along the axial direction of the ferrule, which increases the axial contact area between the spring tongues and the screws, improves the bonding strength between the screws and the spring tongues, and thus ensures the overall fixing strength of the cable tie.

[0031] For example, see Figures 3 to 5 As shown, a plurality of locking teeth 211 are arranged on the side of the spring tongue 21 close to the central axis of the sleeve 2.

[0032] In this technical solution, a plurality of spring tongues are arranged in an equidistant circular array along the inner wall of the ferrule, and two relatively arranged spring tongues are aligned along the axial direction of the ferrule and staggered with the adjacent axial spring tongues. The screw enters the ferrule from the end where the spring tongue is located, and the spring tongue is deformed by force. The screw continues to move, and the teeth on the spring tongue are engaged in the threads of the screw to fix the cable tie as a whole in the corresponding position. The teeth of a plurality of spring tongues are engaged in the threads of the screw from multiple circumferential angles at the same time. The axially staggered spring tongues increase the number of thread turns engaged by the teeth, thereby improving the bonding strength between the spring tongue and the screw, thereby improving the overall fixing strength of the cable tie.

[0033] For example, see Figures 3 to 5 As shown, a pulling tongue 212 protrudes from one end of the spring tongue 21 close to the cable tie 3 .

[0034] In this technical solution, the inner side surface of the tongue is an arc structure, which provides a guide for the screw. By pushing the tongue, the locking teeth are disengaged from the screw thread, which is convenient for removal. The locking tongue of the lock buckle can adopt the same structure as the spring tongue. Its locking teeth cooperate with the serrations of the cable tie to lock the free end of the cable tie. Similarly, the locking teeth of the tongue can be disengaged from the serrations of the cable tie by pushing the tongue, which is convenient for removal.

[0035] For example, see Figures 1 to 5 As shown, the inner wall of the ferrule 2 is concavely provided with a plurality of through grooves 22 arranged along its axial direction, and the spring tongues 21 are respectively arranged in the through grooves 22 .

[0036] In this technical solution, the spring tongue is arranged in the through groove, which is beneficial to reducing the volume of the ferrule and thus reducing the occupied space.

[0037] For example, see Figures 1 to 5 As shown, a connecting boss 221 corresponding to the spring tongue 21 protrudes from the bottom wall of the through slot 22 .

[0038] In this technical solution, the connection boss is arranged so that the corresponding side surface of the spring tongue and the bottom wall of the through groove are arranged at intervals, and there is enough space to accommodate the deformation of the spring tongue.

[0039] For example, see Figures 1 to 5 As shown, a first reinforcing rib 222 protrudes from the open end of the through slot 22 , and the end surface of the first reinforcing rib 222 close to the central axis of the ferrule 2 is an arc surface structure and is coaxially arranged with the ferrule 2 .

[0040] In this technical solution, the first reinforcing rib strengthens the overall strength of the ferrule. When the extrusion of the spring tongue by the screw exceeds the maximum deformation of the spring tongue or the spring tongue fails due to repeated disassembly and assembly, the ferrule can also be fixed by using the self-tapping screw and the first reinforcing rib in combination.

[0041] For example, see Figures 2 to 5 As shown, second reinforcing ribs 32 protrude from both sides of the side of the cable tie 3 away from the saw teeth, and a clearance groove 111 corresponding to the second reinforcing ribs 32 is provided in the clamping groove 11.

[0042] In this technical solution, the second reinforcing rib extends along the length direction of the cable tie to increase the strength of the cable tie and prevent the cable tie from being torn off. The second reinforcing rib cooperates with the clearance groove to prevent the cable tie from lateral sliding, thereby ensuring the functionality of the cable tie.

[0043] Exemplarily, the ferrule 2 is integrally formed with the lock buckle 1 and the cable tie 3 or is separately provided.

[0044] In this technical solution, the ferrule is integrally formed with the lock buckle and the cable tie, which is convenient for production and storage, etc. The ferrule can also be separately provided with the lock buckle and the cable tie for flexible use.

[0045] To sum up, the buckle-type cable tie has a simple structure, and multiple spring tongues are arranged in the clamping sleeve, which can adapt to screws of multiple specifications at the same time, thereby improving the compatibility of the product; multiple teeth are arranged on the spring tongue, thereby improving the binding force with the screws and improving the fixing strength.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0047] The above is only a specific implementation of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
