Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a special fixing and sealing device for motor vehicle license plates.

Referring to fig. 1 and 2, the special fixing and sealing device for the number plate of the motor vehicle comprises a base 1, wherein an embedded groove 11 is formed in the base 1 in an integrated mode, the base 1 is penetrated through the embedded groove 11 along one side of the axis direction of the base 1, a mounting groove 13 is formed in the bottom wall of the embedded groove 11 in an integrated mode, and the mounting groove 13 penetrates through the base 1 along the axis direction of the base 1. Be provided with interior fastener 2 on the base 1, interior fastener 2 and embedded groove 11 grafting cooperation, one side that interior fastener 2 is close to mounting groove 13 is fixed with base 1 riveting. Still be provided with locking bolt on the base 1, locking bolt and the coaxial setting of base 1, locking bolt runs through mounting groove 13 along its self axis direction, the week lateral wall and the 13 clearance fit of mounting groove of locking bolt screw rod. Still be provided with the joint closure 3 on the base 1, joint closure 3 and the coaxial setting of base 1, the one end integrated into one piece that joint closure 3 is close to base 1 has fixed slot 31, and fixed slot 31 wears to establish joint closure 3 along 3 axis directions of joint closure. The inner fastener 2 is positioned in the fixing groove 31, and the edge of the fixing groove 31 is in riveting fit with the inner fastener 2. In the installation, the staff establishes the base 1 cover that the riveting was fixed with interior fastener 2 in the locking bolt outside, passes the mounting hole on the motor vehicle license plate with locking bolt, with the nut thread tightening on the motor vehicle automobile body, in the staff imbeds base 1 with sealing buckle 3 along embedded groove 11 again, makes interior fastener 2 be located fixed slot 31, makes sealing buckle 3 join in marriage with interior fastener 2 joint to accomplish the installation of motor vehicle license plate. In this way, the possibility that a lawless person removes the bolt by rotating the base 1 is reduced, and the anti-theft performance of the sealing device is improved.

Specifically, referring to fig. 2 and 3, the inner fastening member 2 includes a connecting pipe 22, the connecting pipe 22 is disposed coaxially with the base 1, one end of the connecting pipe 22 in the axial direction is provided with a fixing plate 23, the fixing plate 23 extends along the axial direction of the connecting pipe 22 to the side away from the connecting pipe 22, the fixing plate 23 is disposed in a plurality along the circumferential array of the axial direction of the connecting pipe 22, and in the embodiment of the present application, four fixing plates 23 are disposed. One side that stationary blade 23 deviates from each other and 13 inside wall butts of mounting groove, the staff buckle stationary blade 23 through the riveting mode of punching press, make stationary blade 23 cladding on 13 week lateral walls of mounting groove to buckle 2 and base 1 riveting fixed in making. The locking bolt is in clearance fit with the fixing plate 23. In this way, the stability of the connection between the inner buckle 2 and the base 1 is improved, and the separation of the inner buckle 2 from the base 1 caused by external force is reduced.

One end of the connecting pipe 22, which is away from the fixing piece 23, is integrally formed with an annular clamping piece 21, the annular clamping piece 21 is sleeved outside the connecting pipe 22, and the annular clamping piece 21 and the connecting pipe 22 are coaxially arranged. The annular clamping piece 21 gradually shrinks from the side close to the mounting groove 13 to the side away from the mounting groove 13 along the axial direction of the connecting pipe 22.
