[0001] The utility model belongs to the technical field of bolts, and in particular relates to an efficient automobile fixing bolt. Background Art

[0002] A bolt is a mechanical fastener used to connect and fix parts. It consists of a cylinder with threads and a part with threaded holes. By rotating the bolt, its threads and the threaded holes engage with each other to achieve the connection and fixation of parts. In the automotive field, automotive bolts are specially designed for connecting and fixing various key components of the car. They need to have high strength, corrosion resistance, fatigue resistance and reliable fastening performance to ensure the safety and stability of the car during driving. In the use of existing technologies, automotive bolts may still have problems such as loose fixation after being fixed, resulting in shaking and falling off. Utility Model Content

[0003] In order to overcome the problem of using traditional bolts to connect various parts of the car, the bolts may still be loose after being fixed, causing the bolts to shake and fall off.

[0004] The technical solution of the utility model is: an efficient automobile bolt fixing device, comprising a first bolt assembly; further comprising a second bolt assembly, a movable assembly, a fixed assembly and a friction assembly; the second bolt assembly is arranged on the first bolt assembly; the second bolt assembly is arranged on a movable assembly for moving up and down; the movable assembly is arranged on a fixed assembly for fixed clamping; the first bolt assembly is arranged on a friction assembly for increasing friction.

[0005] Preferably, when fixing and connecting various parts of an automobile, the first bolt assembly is threadedly installed in the connecting hole, and then the second bolt assembly is rotated with a screwdriver, so that the second bolt assembly moves up and down in the first bolt assembly through the friction assembly. When the second bolt assembly rotates, it drives the movable assembly to move up and down. When the movable assembly moves up and down, it drives the fixed assembly in the first bolt assembly to move left and right, so that the first bolt assembly is stably fixed at the installation place between the automobile firmware, which solves the problem that the bolts may still be loosely fixed after being fixed when using traditional bolts, causing the bolts to shake and fall off.

[0006] Preferably, the first bolt assembly includes a first stud, a first groove body, a second groove body, a first limiting groove, a second limiting groove and a third limiting groove; the first stud is provided with a first groove body at the upper end; the first stud is provided with a second groove body inside; the second groove body and the first groove body are interconnected; the inner wall of the second groove body is provided with symmetrical first limiting grooves; the outer wall of the first stud is provided with two second limiting grooves; the upper end of the inner wall of the second limiting groove is provided with a third limiting groove; the second limiting groove and the second groove body are interconnected, and the outer wall of the first stud is threadedly installed in the firmware between the cars to achieve preliminary fixation.

[0007] Preferably, the second bolt assembly includes a second stud and a cross slot; the second stud is movably arranged inside the second slot body; a cross slot is provided at the upper end of the second stud, and the second stud can be moved up and down on the inner wall of the second slot body by rotating the cross slot with a screwdriver.

[0008] Preferably, the movable component includes a first circular ring block, a first threaded groove, a first limiting column and a first oblique tooth groove; the inner wall of the second groove body is movably provided with a first circular ring block; the inner wall of the first circular ring block is provided with a first threaded groove; the first threaded groove and the second stud are adapted to each other; the outer wall of the first circular ring block is fixedly connected with two first limiting columns; the outer wall of the first limiting column is provided with a first oblique tooth groove; the first limiting column and the first limiting groove are adapted to each other. When the second stud rotates downward, the first circular ring block will be restricted by the first limiting column on the first limiting groove and cannot rotate. When the cross groove rotates downward, the first circular ring block will be driven to move downward.

[0009] Preferably, the fixing assembly includes a cylinder, a second limiting column, a second oblique tooth groove and a clamping column; the inner wall of the second limiting groove is movably provided with a cylinder; the upper end of the cylinder is fixedly connected to the second limiting column; the second limiting column and the third limiting groove are adapted; the ends of the cylinders close to each other are provided with a second oblique tooth groove; the second oblique tooth groove and the first oblique tooth groove are meshed with each other; the end of the cylinder facing the notch is fixedly connected with a clamping column, and the cylinders movably provided on the inner walls of the two second limiting grooves are meshed with the first oblique tooth groove through the second oblique tooth groove. When the first circular ring block moves downward, it will drive the cylinder to move toward the notch. The second limiting column, under the restriction of the third limiting groove, prevents the cylinder from rotating on the inner wall of the second limiting groove, resulting in the inability to displace the cylinder. When the first stud is fixed on the automotive firmware, the thread is clamped by the second limiting column on the cylinder to achieve secondary fixation, which can solve the problem of subsequent falling off of the bolt.

[0011] Preferably, the two second limiting grooves are centrally symmetrically arranged on the outer wall of the first stud, so as to facilitate the cylinder to clamp the outer wall of the first stud in two opposite directions when it moves.

[0012] Beneficial effects of the utility model:

[0013] 1. The cylinder movably arranged on the inner wall of the two second limiting grooves meshes with the first oblique tooth groove through the second oblique tooth groove, so that the meshing point between the two tooth grooves generates relative movement in the axial direction, forming a rack transmission movement. When the first circular ring block moves downward, it will drive the cylinder to move toward the notch. The second limiting column is restricted by the third limiting groove to prevent the cylinder from rotating on the inner wall of the second limiting groove, resulting in the inability to displace the cylinder. When the first stud is fixed on the automobile fastener, the second limiting column on the cylinder is used to clamp the thread to achieve secondary fixation, which can solve the problem of subsequent falling off of the bolt;

[0014] 2. By rotating the second stud, the outer wall of the second stud is displaced up and down through the second thread groove provided on the inner wall of the second circular ring block, so as to prevent the second stud from being vibrated by the car after installation, causing the second stud to be displaced up and down, thereby causing the fixing assembly to be loosened during fixing;

[0015] 3. When the second stud rotates downward, the first circular ring block will be restricted by the first limiting column on the first limiting groove and cannot rotate. When the cross groove rotates downward, the first circular ring block will be driven to move downward. BRIEF DESCRIPTION OF THE DRAWINGS
