DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0022] Please refer to Figures 1 to 3 The utility model provides a technical scheme: a kind of automobile corner piece which can be quickly disassembled, including outer corner piece 1 and the inner corner piece 2 in outer corner piece 1, outer corner piece 1 is equipped with waist type butt joint hole 11 on three outer side walls, the inner cavity formed between this waist type butt joint hole 11 and outer corner piece 1 and inner corner piece 2 is communicated, and the mounting hole of evenly distributed along the outer edge is equipped on the outer side wall of outer corner piece 1, and outer corner piece 1 is installed on the frame of automobile by the cooperation of bolt and mounting hole.

[0023] In the technical scheme, limiting plate 3 which is adapted to waist type butt joint hole 11 in width direction is also included, that is to say, the width of limiting plate 3 is same with the width of waist type butt joint hole 11, and the length of limiting plate 3 is less than the length of waist type butt joint hole 11.The waist type connecting hole 31 is equipped on the board surface of the limiting plate 3, and limiting post 32 is fixedly connected on both sides of the limiting plate 3, when using, the waist type connecting hole 31 is used to pass through screw rod, the notch 12 which is located on both sides of waist type butt joint hole 11 and communicated with the waist type butt joint hole 11 is equipped on the outer side wall of outer corner piece 1, the notch 12 is adapted to limiting post 32, that is to say, limiting post 32 is aligned with notch 12, then the limiting plate 3 is placed into waist type butt joint hole 11, when limiting post 32 enters the inner cavity and sliding limiting plate 3, the limiting plate 3 is hung, when screw rod is tightened, the external component and outer corner piece 1 are tightly connected, when the external component needs to be disassembled, by loosening bolt and then moving limiting plate 3, limiting plate 3 can be separated from outer corner piece 1, and the setting has the advantages that it is more convenient and fast to install fixing clamp (such as bolt) and disassemble and connect the component of outer corner piece 1.

[0024] Further, the limiting plate 3 is a waist-shaped structure, and the number of limiting stakes 32 on both sides thereof is two, and the number of notches 12 on both sides of the waist-shaped butt joint hole 11 is two and is arranged close to one end of the waist-shaped butt joint hole 11, which can improve the stability of the limiting plate 3 after being hung with the outer corner piece 1. The cross section of the limiting stake 32 is circular, which can reduce the resistance when the limiting stake 32 and the notch 12 are butted, so that the limiting stake 32 is more convenient to enter and exit the notch 12.

[0025] In the embodiment, limiting grooves 13 are arranged on the three inner side walls of the outer corner piece 1 and are located on both sides of the waist-shaped butt joint hole 11, the limiting grooves 13 are matched with the limiting stakes 32, and after the limiting stakes 32 enter the limiting grooves 13, the limiting grooves 13 limit the limiting stakes 32, so as to prevent the displacement of the limiting plate 3.

[0026] In the embodiment, an anti-skid thread 33 is arranged on one side of the limiting plate 3 and is located on the outer periphery of the waist-shaped connecting hole 31, which can improve the friction force of the contact between the anti-skid thread 33 and the fixing clamp (such as a bolt), so as to avoid the problem of slipping.

[0027] In the embodiment, a resistance-increasing adhesive tape 311 is arranged on the opposite side in the waist-shaped connecting hole 31, which can make the screw stay at a fixed point when passing through the waist-shaped connecting hole 31, so as to avoid the problem of clatter, and the arrangement facilitates the control of the displacement of the limiting plate 3 in the waist-shaped butt joint hole 11 by the screw.

[0028] Further, an arc-shaped groove 3111 is arranged on one side of the resistance-increasing adhesive tape 311 and is uniformly distributed along the length direction, which can be buckled on the outer peripheral wall of the screw during use, and the arrangement can further improve the reliability of the limiting of the screw.

[0029] Working principle: during use, the outer corner piece 1 is first installed on the vehicle frame by a screw, then the bolt on the component to be connected is passed through the waist-shaped connecting hole 31 of the limiting plate 3, then the nut connected with the screw is installed on one side of the limiting plate 3, the nut is opposite to the anti-skid thread 33, during butt joint, the limiting stake 32 on the limiting plate 3 is aligned with the notch 12 by holding the screw, then the limiting plate 3 is placed in the waist-shaped butt joint hole 11 and the limiting stake 32 is ensured to enter the inner cavity, then the limiting plate 3 is moved so that the limiting stake 32 enters the limiting groove 13, and finally the bolt is tightened to complete the fastening connection of the outer component and the outer corner piece 1, and reverse operation can quickly disassemble the above components.

[0030] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
