Description

Technical Field

[0001] The utility model belongs to the technical field of bolt anti-falling, in particular to an automobile bolt with an anti-falling structure. Background Art

[0002] A bolt is a cylindrical, threaded fastener that fits a nut. Composed of a head and a shank, it is used to securely connect two parts with through-holes. This type of connection is called a bolted connection. Removing the nut from the bolt allows the two parts to separate, making a bolted connection removable.

[0003] Currently, bolts used in automobiles generally use anti-loosening bolts to prevent the loosening between the bolts and nuts during long-term use of the car, thereby affecting the firmness and safety of automobile parts. Existing automobile anti-loosening bolts and nuts are generally used in conjunction with one anti-loosening method to achieve the anti-loosening effect, but it cannot meet the actual long-term use effect, thereby affecting the overall quality of the car.

[0004] To this end, we provide an automobile bolt with an anti-falling structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an automobile bolt with an anti-dropout structure, wherein an L-shaped stop plate is sandwiched between a nut and a first transverse plate, so that one end of the L-shaped stop plate is tightly fitted with a notch, and a brake ear plate on the L-shaped stop plate is bent and clamped on the outer wall of the nut, thereby locking the nut and the bolt. In addition, a cotter pin is added to further improve the firmness between the first transverse plate and the second transverse plate, effectively improving the overall quality of the automobile, and solving the problem that the existing automobile anti-dropout bolts and nuts generally use one anti-dropout method to achieve the anti-dropout effect, but cannot meet the actual long-term use effect, thereby affecting the overall quality of the automobile.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is an automobile bolt with an anti-falling structure, comprising a first transverse plate; a second transverse plate is provided on the top of the first transverse plate, a bolt is provided between the first transverse plate and the second transverse plate, an L-shaped stop plate is provided on the sliding sleeve of the peripheral side surface, and the two opposite side surfaces of the L-shaped stop plate are fixedly connected with stop ear plates; a nut that contacts and cooperates with the stop ear plate is threadedly connected to the peripheral side surface of the bolt, a notch is provided at the bottom of the second transverse plate, and the L-shaped stop plate contacts and cooperates with an inner side surface of the notch.

[0008] The present invention is further configured such that the bolt is in sliding engagement with the second transverse plate, and the first transverse plate is in threaded engagement with the second transverse plate.

[0009] The present invention is further configured such that a threaded hole is provided through the top of the first transverse plate and is threadedly engaged with the bolt, and a socket is provided through the top of the second transverse plate and is slidably engaged with the bolt.

[0010] The present invention is further configured such that a first through hole is formed through the side surface of the bolt.

[0011] The utility model is further configured such that a second through hole adapted to the first through hole is penetrated through the stop ear plate, and a third through hole is penetrated through two opposite side surfaces of the nut.

[0012] The present invention is further configured such that a cotter pin is inserted between the first through hole, the two second through holes, and the two third through holes.

[0013] The present invention is further configured such that a cylindrical hole is provided on the top of the L-shaped stop plate and is in sliding engagement with the bolt.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model passes the bolt through the insertion hole and the threaded hole, then sleeves the L-shaped stop plate on the outer wall of the bolt, and at the same time, clamps one end of the L-shaped stop plate in the notch on the first horizontal plate, and then threadedly connects the nut to the bolt. After the nut completes the fixing of the first horizontal plate and the second horizontal plate, the stop ear plate on the L-shaped stop plate is bent so that the stop ear plate is tightly attached to the outer wall of the nut, thereby completing the locking of the nut. The similar nut and bolt have an anti-slip effect, thereby improving the firmness of the connection between the first horizontal plate and the second horizontal plate.

[0016] 2. After the utility model completes fixing the first horizontal plate and the second horizontal plate by the nut, the cotter pin is then aligned with the second through hole, the third through hole, and the first through hole and passed through, thereby completing the locking of the bolt, the nut and the L-shaped stop plate, further reducing the looseness between the bolt and the nut, thereby improving the firmness of the first horizontal plate and the second horizontal plate.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
