Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile accessories, in particular to a stable fastener for automobile interior decoration installation. BACKGROUND

[0002] Although small, automobile interior decoration fasteners play a huge role. They not only concern the delicacy of automobile interior decoration and driving experience, but also concern the safety of passengers. Automobile interior decoration fasteners can stably connect various components together to form a complete interior decoration system. This helps to improve the overall structural stability of the automobile and ensure the safety of passengers during driving.

[0003] Most conventional fasteners are in the form of bolts and nuts. First, the bolt is inserted into the reserved hole of the vehicle frame, then the decoration is fitted on the bolt, then the nut is locked, and finally the bolt and the bolt are hidden by the cover. If the reserved hole position on the vehicle frame is in a remote corner, and there is no reserved position on the vehicle frame to install the bolt, the bolt cannot be installed in the reserved hole of the vehicle frame, which leads to the bolt being unable to fix the decoration, resulting in the decoration shaking and affecting the driving experience.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a stable fastener for automotive interior installation, which has the following advantages:

[0016] 1. This automotive interior mounting fastener uses a sturdy fastener. The nail plate is pre-inserted into a pre-drilled hole in the frame that is slightly larger than itself. Then, the restriction on the push plate is released, and the spring pushes the protrusion to slide out. After the four protrusions expand, they will ensure that the nail plate will not separate from the frame. During this process, the fastener can be inserted into the pre-drilled hole in the frame in a remote corner, and it can also be inserted into a place where the frame has little clearance, thus achieving quick insertion of the fastener into the pre-drilled hole in the frame.

[0017] 2. This automotive interior installation fastener has a locking nut threaded onto the screw tube, which can press and lock the trim leather to ensure its stability. Then, a cap is fitted onto the end of the screw tube, which is flush with the trim leather to ensure that there are no dents on the trim leather and improve the overall aesthetics.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-2 A type of sturdy fastener for automotive interior installation includes a frame 1 and a trim 2. Fastening nails 3 are inserted inside the frame 1 and the trim 2. One end of the fastening nail 3 is fitted with a cap 4, which is flush with the surface of the trim 2 to ensure the aesthetics of the interior.

[0025] Please see Figures 2-4 The fastening nail 3 includes a nail plate 31, which is inserted into a pre-drilled hole on the frame 1. A screw tube 32 is fixedly installed on the side of the nail plate 31. A locking screw 33 is threaded on the outside of the screw tube 32. The decorative leather 2 is fitted onto the screw tube 32. Tightening the locking screw 33 will press and fix the decorative leather 2.

[0026] Please see Figures 2-4 The nail plate 31 has four mounting grooves 34 on its outer side, arranged in a circular array. The surface of the nail plate 31 has strip holes 35, which are connected to the mounting grooves 34.

[0027] Please see Figures 2-4 A sealing frame 36 is fixedly installed at the opening of the mounting slot 34. A protrusion 37 is inserted inside the sealing frame 36. A limiting plate 38 is fixedly installed on the side of the protrusion 37. A spring 39 is provided on the side of the limiting plate 38. Pre-drilled holes corresponding to the spring 39 are opened inside the protrusion 37 and the limiting plate 38, and the spring 39 is installed inside these pre-drilled holes. The spring 39 can push the protrusion 37 outwards. After the four protrusions 37 expand, the protrusions 37 and the pre-drilled holes in the frame 1 mutually restrict each other.

[0028] Please see Figures 2-4 A push plate 310 is fixedly installed on the top of the limiting plate 38. The top of the push plate 310 passes through the strip hole 35 and extends to the outside of the nail plate 31. By sliding the push plate 310, the protrusion 37 can be moved backward. A baffle 311 is fixedly installed on the side of the limiting plate 38. The baffle 311 is located below the strip hole 35. The length and width of the baffle 311 are greater than the length and width of the strip hole 35. After the four protrusions 37 expand, the position of the push plate 310 moves, so that the baffle 311 can block the strip hole 35.

[0029] Working principle: When in use, the nail plate 31 is inserted into the reserved hole of the frame 1 that is slightly larger than itself. Then, the restriction on the push plate 310 is released, and the spring 39 pushes the protrusion 37 to slide out. After the four protrusions 37 expand, they will ensure that the nail plate 31 will not separate from the frame 1. During this process, it is ensured that the fastening nail 3 can be inserted into the reserved hole of the frame 1 in a remote corner, and the fastening nail 3 can also be inserted into a place where the frame 1 has little space to avoid, so as to achieve quick insertion of the fastening nail 3 into the reserved hole of the frame 1.

[0030] A locking screw plate 33 is threaded onto the screw tube 32, which can press and lock the decorative skin 2 to ensure the stability of the decorative skin 2. Then, a cap 4 is fitted onto the tail end of the screw tube 32. The cap 4 is flush with the decorative skin 2, thereby ensuring that there are no dents on the decorative skin 2 and improving the overall aesthetics.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
