Detailed Description
The invention is described in detail below with reference to the accompanying drawings:
referring to fig. 2 to 4, the door connection structure for preventing theft and dropping of the grid cabinet comprises a door body 1, a head pin shaft 2 and a fixing part 3 arranged on the cabinet body, wherein the fixing part 3 is positioned on one side of the upper part of the door body 1, and a first square hole 31 is arranged on the fixing part 3. One side of the door body 1 corresponding to the fixing piece 3 is provided with an installation cavity, and the installation cavity is communicated with the outside through a second square hole 11 at the top of the door body 1. The first square hole 31 and the second square hole 11 are both square holes, and the first square hole 31 is located right above the second square hole 11. The belt head pin shaft 2 is provided with a first square body 4 and a second square body 5 at intervals along the length direction, the first square body 4 is matched with the first square hole 31, and the second square body 5 is matched with the second square hole 11.
The headed pin shaft 2 comprises a pin rod 21 and a limiting head 22, the pin rod 21 is a straight rod with an equal section, the limiting head 22 is positioned at one end of the pin rod 21 and is connected with the pin rod into an integral structure, the limiting head 22 is a flat head or a round head, and the center of the limiting head is positioned on the axis of the pin rod 21. The other end of the pin rod 21 is provided with a tapered part 23, the tapered part 23 is of a cross structure, the outer contour of the tapered part 23 is conical, and the large head end of the tapered part 23 and the corresponding end of the pin rod 21 are coaxially and fixedly connected into a whole structure. Specifically, the first square body 4 and the second square body 5 are arranged along the direction from the stopper 22 to the tapered portion 23, and are fixedly connected integrally with the pin rod 21. The limiting head 22 is connected with the first square body 4 to form an integral structure, and part of the edge of the limiting head 22 protrudes outwards relative to the side wall of the first square body 4.
The cross section of the first square body 4 and the cross section of the second square body 5 are both square structures, and the centers of the first square body and the second square body are both positioned on the axis of the pin rod 21. The four faces of the first square body 4 correspond to the four side faces of the second square body 5 one by one, and the length of the first square body 4 and the length of the second square body 5 are both equal to the diameter of the pin rod 21.
The other end of the headed pin shaft 2 passes through the first square hole 31 of the fixing part 3 and extends into the mounting cavity of the door body 1, and the first square body 4 is positioned in the first square hole 31. The second square hole 11 is positioned between the first square body 4 and the second square body 5, and the door body 1 is rotationally connected with the fixing part 3 through the belt head pin shaft 2. In the closed state of the door body 1, the second square hole 11 is shifted by 45 ° counterclockwise or clockwise with respect to the first square hole 31. After the assembly is completed, the distance between the upper surface of the first square hole 31 and the bottom of the first square body 4 along the axis direction of the pin shaft is greater than the distance between the bottom of the second square hole 11 and the upper surface of the second square body 5 along the axis direction of the pin shaft.
The fixing piece 3 is installed on the cabinet body of the grid cabinet and located above one side of the door body 1, and the fixing piece 3 corresponds to the installation cavity of the door body 1 and the second square hole 11 up and down. The installation process of the anti-theft and anti-drop door body connecting structure for the lattice cabinet comprises the following steps: the door body 1 is in an open state, the plane of the door body 1 and the plane of the door frame of the lattice cabinet or the express cabinet form an included angle of 45 degrees, and at the moment, four straight edges of the first square hole 31 on the fixing piece 3 respectively correspond to four straight edges of the second square body 5 on the door body 1 one by one. The headed pin shaft 2 is vertically aligned with the first square hole 31 from the upper part of the fixing member 3, and the tapered part 23 of the headed pin shaft is made to penetrate into the first square hole 31 and the second square hole 11 in sequence.
After the limiting head 22 contacts with the upper surface of the fixing part 3, the pin shaft 2 with the head is prevented from continuing to move downwards, the first square body 4 of the pin shaft 2 with the head falls into the first square hole 31, and the first square hole 31 limits the pin shaft 2 with the head so that the pin shaft 2 with the head cannot rotate around the axis of the pin rod 21. After the second square body 5 passes through the second square hole 11 on the door body 1, the second square hole 11 enters the installation cavity of the door body 1, at the moment, the second square hole 11 is positioned between the first square body 4 and the second square body 5, the door body 1 is rotated to close the door body, the belt head pin shaft 2 does not rotate, the inner walls of the four sides of the second square hole 11 are in rotating fit with the outer side wall of the pin shaft 2, and the second square body 5 and the second square hole 11 are in a dislocation state under the closing state of the door body 1.
After the assembly is completed, because the distance between the upper surface of the first square hole 31 and the bottom of the first square body 4 along the axis direction of the pin shaft is greater than the distance between the bottom of the second square hole 11 and the upper surface of the second square body 5 along the axis direction of the pin shaft, when the second square body 5 and the second square hole 11 are in a staggered state, the belt head pin shaft 2 is pulled upwards to the outside of the bottom of the first square hole 31 to block the second square body 5 to continue to move upwards, the first square body 4 is still located in the first square hole 31, and the belt head pin shaft 2 cannot rotate, therefore, when the second square body 5 and the second square hole 11 are in a staggered state, the belt head pin shaft 2 cannot be pulled out, so that the anti-theft and anti-falling effects are achieved on the door body 1, and particularly, the.
The disassembly process of the anti-theft and anti-drop door body connecting structure for the grid cabinet can be operated reversely according to the installation process.
