The invention relates to a server comprising a base plate, a circuit board and a buckling mechanism, wherein the buckling mechanism is used for detachably installing the circuit board on the base plate and comprises a bracket and a sliding part, wherein the bracket is provided with a connecting pin; the connecting pin comprises a rod body and an end part, wherein the rod body is connected with the bracket, the end part is formed on the tail end of the rod body, and the end part is bigger than the rod body; the sliding part is provided with a clamping groove and a sliding groove, wherein the sliding groove corresponds to the connecting pin; the clamping groove comprises a circular hole and a limit groove, the circular hole faces to the sliding groove, the limit groove is communicated with the circular hole, and the diameter of the circular hole is larger than the width of the limit groove; the sliding groove comprises an opening and a slot, wherein the opening faces to the clamping groove, the slot is communicated with the opening, the opening is larger than the end part of the connecting pin, and the slot is smaller than the end part of the connecting pin but not smaller than the rod body of the connecting pin; the end part of the connecting pin penetrates through the opening of the sliding groove; and the sliding part slides towards a first direction relative to the bracket to enable the rod body of the connecting pin to be clamped into the slot of the sliding groove, therefore, the disassembly and the assembly of the circuit board can be realized through the self buckling matching of the buckling mechanism, without screws, screwdrivers, and the like, and the advantages of simpleness and convenience are achieved.

The invention provides a one-way self-buckling type rotating wheel sliding lock bar. The one-way self-buckling type rotating wheel sliding lock bar comprises an electric meter box door sheet, an electric meter box base and a lock bar body. The electric meter box door sheet is arranged on the lock bar body. The lock bar body is connected with the electric meter box base in a buckled mode. The lock bar body is further provided with a lock bar rotating wheel. The lock bar body is provided with a rotating wheel lock corresponding to the lock bar rotating wheel. The lock bar rotating wheel is composed of a rotating wheel and a rotating lock catch. The rotating lock catch is at least provided with a convex lock catch body. The rotating wheel and the rotating lock catch are of an integrated structure. The electric meter box door sheet is provided with electric meter box door sheet screw holes. The electric meter box door sheet and the lock bar body are fixed together through screws. Multiple lock catches are arranged on the lock bar body. The one-way self-buckling type rotating wheel sliding lock bar has the advantages that the lock bar body is driven by the lock bar rotating wheel to move, the lock catches on the lock bar body are buckled with a box door, the structure is simple, use is convenient, safety is high, and service life is long.

The invention relates to a riveting part. The riveting part comprises a head portion, a guiding pillar and one or more locking portions, wherein the guiding pillar extends out of the head portion; thecross section of the guiding pillar is matched with a mounting hole in a to-be-riveted plate, so that the guiding pillar can be inserted into the mounting hole and move in the axial direction of theguiding pillar; and the locking portions extend out of the head portion and partly or wholly surround the guiding pillar. Each locking portion comprises one or more self-buckling grooves and discharging portions. The self-buckling grooves extend around the guiding pillar in the circumferential direction and used for containing materials, squeezed to flow, of the to-be-riveted plate when the to-be-riveted plate is riveted through the riveting part. The discharging portions are located at the two sides of the self-buckling grooves and used for squeezing the materials of the to-be-riveted plate,and thus, the materials flow into and are maintained in the self-buckling grooves.

The invention relates to a wall of a building and especially relates to a self-buckling combined wall plate in a wall of a building. The self-buckling combined wall plate comprises at least two sandwich side plates arranged in parallel. Each one of the at least two sandwich side plates comprises a color steel plate, polyurethane layers and calcium silicate layers, wherein the polyurethane layers are arranged between the color steel plate and the calcium silicate layers; and the color steel plate is provided with buckle-type convex teeth. The color steel plates of the at least two sandwich side plates are located between the calcium silicate layers of the at least two sandwich side plates. The buckle-type convex teeth of the at least two sandwich side plates are staggered. The self-buckling combined wall plate has the advantages that inclinedly inserted steel bars connected between wall plates are avoided so that construction processes are simple; only pre-prepared sandwich side plates are adopted so that transport and installation are convenient; and a steel use amount is less so that a cost is low.
