Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1-2, a nut case fastening a plastic sheathing board has:
a housing 101;
a nut 201 mounted in the housing 101;
the clamping groove 102 is arranged at the bottom of the shell 101, and the clamping groove 102 can be clamped into the upper decorative plate 301;
a lower decorative plate 304 that can be attached to the upper decorative plate 301;
and a bolt 401 capable of passing through the lower decorative plate 304 to be screw-fitted to the nut 201.
A square opening 302 is arranged on the upper decorative plate 301, and the clamping groove 102 is clamped in the square opening 302; the lower ornamental plate 304 is provided with a circular opening 305, and a screw of the bolt 401 passes through the circular opening 305.
Two sides of the shell 101 are provided with clamping feet 103 of the limiting nut 201; a circular hole 104 is formed on the housing 101 at a position corresponding to the nut 201. The upper trim 301 is provided with a step 303, and the step 303 contacts the lower trim 304.
The nut box is composed of an outer shell 101 and an inner nut 201, two clamping grooves 102 formed by flanging and bending are formed in the lower surface of the shell 101, the clamping grooves 102 are opened in the front direction and the rear direction, and the distance between the two clamping grooves 102 is smaller than the width of the inner nut 201. The clamping groove 102 is used for restraining the nut 201 and clamped on the plastic decorative plate, the opening height of the clamping groove 102 is gradually reduced, and the height of the most end part is slightly smaller than the thickness of the decorative plate to be matched. The left and right surfaces of the shell 101 are respectively provided with a clamping pin 103, the root of the clamping pin 103 is connected to the upper surface of the shell 101, the bending direction of the clamping pin 103 is downward, and the height of the clamping pin 103 is smaller than the thickness of the nut 201. The function of the locking leg 103 is to restrain the nut 201 from falling out of the housing 101. The upper surface of the shell 101 is provided with a round hole 104, and the size of the round hole 104 is larger than the thread size of the nut 201. The nut 201 is arranged inside the shell 101, the nut 201 is square, the edge of the nut 201 is restrained by the front edge and the rear edge of the shell 101 and the left clamping leg and the right clamping leg 103, the length of the shell 101 in the front direction and the rear direction and the left direction and the right direction is larger than the width of the nut 201, the nut 201 can slightly move inside the shell 101 but cannot be separated, and the center of the nut 201 is provided with a thread for connecting a bolt 401.
The fixing device is suitable for occasions needing to fix two layers of plastic decorative plates. The use mode of the nut box is that the outer shell 101 of the nut box is clamped on the opening of the upper plastic decorative plate through the bottom clamping groove 102, the upper decorative plate 301 is provided with a square opening 302, and the size of the square opening 302 of the upper decorative plate 301 is slightly larger than the distance between the bottom clamping grooves 102 of the shell 101. The opening height of the clamping groove 102 at the bottom of the nut box is slightly smaller than the thickness of the decorative plate, and the nut box is fixed on the decorative plate through the deformation of the clamping groove 102.
