Description

Technical Field

[0001] The utility model relates to the field of automobile plastic buckles, and more specifically to an automobile plastic buckle device which is easy to disassemble and assemble. Background Art

[0002] There are many types of automotive plastic clips, including a plastic clip used between an automotive plastic panel and an automotive metal panel, which is composed of a screw part and a base part. The screw parts of the existing automotive plastic clips are mostly similar to the structure of screws, with an external thread structure on the outer wall of the nail body section. When in use, the nail body section is screwed into the base part using the external thread structure, and then screwed out in the opposite direction when disassembled. Although such a structural form is relatively convenient to process and has a high tightening structural strength, such a structural form is not very convenient for the rapid disassembly and assembly of the screw part and the base part. When a large number of similar clips need to be disassembled, it will undoubtedly increase the time for disassembly and assembly and affect work efficiency. Therefore, we propose an automotive plastic clip device that is easy to disassemble and assemble to solve the above-mentioned problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4 , a plastic buckle device for automobiles that is easy to disassemble and assemble, comprising a screw member 1 and a base member 5, wherein the screw member 1 comprises a nail head section 2, a nail body section 3 and protruding ends 4 fixedly connected to both sides of the outer wall of the nail body section 3, and the two protruding ends 4 have the same structure, and the base member 5 comprises an extruded edge section 6 and an expansion claw section 7 fixedly connected to both sides of the bottom of the extruded edge section 6, and the two expansion claw sections 7 have the same structure;

[0025] A through hole 601 is provided at the inner center of the extrusion edge segment 6, and the inner wall of the through hole 601 is parallel to the inner side wall between the two expansion claw segments 7. The outer wall of the expansion claw segment 7 is provided with a raised edge 701. A longitudinal guide groove 702 and a transverse guide groove 703 are provided on the inner side wall of the expansion claw segment 7. The bottom of the longitudinal guide groove 702 penetrates the top of the transverse guide groove 703, and the top of the longitudinal guide groove 702 extends to the top of the through hole 601. Both ends of the transverse guide groove 703 penetrate to both sides of the expansion claw segment 7. Two extraction notches 602 are also provided on the through hole 601.

[0026] The use principle of this kind of automobile plastic buckle device that is easy to disassemble and assemble is:

[0027] First, insert the two expansion claw sections 7 of the base member 5 into the through hole at the connection between the automobile plastic part and the metal part, and then insert the nail body section 3 of the screw member 1 into the base member 5 through the through hole 601. At this time, it is necessary to ensure that the protruding ends 4 on both sides of the outer wall of the nail body section 3 correspond to the two longitudinal guide grooves 702. After insertion, since the distance between the tapered parts of the two protruding ends 4 is greater than the distance between the inner side walls of the two expansion claw sections 7, a supporting expansion effect can be formed between the two expansion claw sections 7.

[0028] When the plastic clip needs to be removed, the screw component 1 is first rotated to rotate the two protruding ends 4 to positions corresponding to the two extraction notches 602, and then the screw component 1 can be pried up by clamping the tool on the raised edge 202, thereby facilitating the subsequent complete extraction of the screw component 1. Finally, after the screw component 1 is pulled out, there is a lack of support between the two expansion claw sections 7, thereby being in a contracted state, so the base component 5 can be pulled out at this time.

[0029] Embodiment 2:

[0030] In view of the above embodiment 1, for further description, refer to Figure 2 and Figure 4 A slotted socket 201 is provided on the top of the nail head section 2, and the direction of the slotted socket 201 is the same as the direction between the two raised ends 4. A raised edge 202 is also provided between the nail head section 2 and the nail body section 3. The outer wall diameter of the raised edge 202 is larger than the inner wall diameter of the through hole 601. The distance between the tapered portions of the two raised ends 4 is larger than the distance between the inner side walls of the two expansion claw sections 7. The screw member 1 and the base member 5 are both polyhedral structures that are separately injection-molded as a whole by plastic material, and the bottom of the nail body section 3 is a tapered structure.

[0031] The slotted socket 201 is convenient for plugging with a slotted screwdriver, and the direction of the slotted socket 201 is the same as the direction between the two protruding ends 4, which can play a role in marking the positions of the two protruding ends 4, facilitating the subsequent rotation of the screw component 1. The raised edge 202 can create a certain gap between the nail head section 2 and the extruded edge section 6, facilitating the subsequent removal process.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
