Problems solved by technology

In the prior art, in order to prevent the veneer from shrinking and the gap between the fastener, so that the veneer and the fastener are disconnected, the veneer is usually closely arranged or there is a gap, so that when the temperature rises, the veneer Linear expansion occurs and the expansion exceeds the gap distance, and the adjacent facings are squeezed against each other, and the facings are easily squeezed and broken, which is very easy to cause falling from high altitudes, posing a great safety hazard

Embodiment 1

[0033] Such as Figure 1-3 As shown, the elastic anti-loosening locking mechanism of the wall pendant includes a bearing piece 1 and a spring card 2, and a locking block 3 is arranged on one side of the bearing piece 1, and the locking piece 3 and the spring card 2 A connection structure 4 is provided between them, and the spring card 2 is provided with a clamping hole 5, and the spring card 2 is slidably clamped on the locking block 3 through the clamping hole 5, and is fixed by the connection structure 4 Connected to the locking block 3. Such as Figure 4 As shown, those skilled in the art should be able to obtain technical enlightenment, two locking blocks 3 are provided on one side of the carrier sheet 1 . Those skilled in the art should also be able to obtain the technical revelation that multiple locking blocks 3 are provided on one side of the carrier sheet 1 .

Embodiment 2

[0048] The basic principle of the second embodiment is basically the same as that of the first embodiment, the difference is that, as Figure 4 As shown, a connection seat 16 is provided between the carrier sheet 1 and the mounting seat 14, and at least one upwardly folded slider 17 is provided on the connection seat 16, and a U-shaped chute is provided on the carrier sheet 1. 18 and the U-shaped chute 18 can be interactively connected on the slide block 17, and one side of the slide block 17 is provided with a lateral movement stopper. During the installation process, when the connecting plate 13 deviates from the installation space on the thermal insulation integrated board, the carrier sheet 1 is moved to adapt to the installation holes on the thermal insulation integrated board, so as to achieve the technical effect of easy installation. Simultaneously, the lateral movement stopper limits the moving position of the carrier sheet 1 .

Embodiment 3

[0050] The basic principle of the third embodiment is basically the same as that of the first embodiment, the difference is that, as Figure 6 As shown, the spring card 2 is V-shaped, and the spring card 2 includes an elastic arc portion, and the elastic arc portion is integrally formed with elastic sheets 19 twice, and the sides of the two elastic sheets away from the elastic arc portion are respectively provided with locking The sheet 8, the clamping sheet 8 and the elastic sheet form an angle, and the angle between the clamping sheet 8 and the horizontal plane is greater than 45 degrees. In this embodiment, the angle between the clamping sheet 8 and the horizontal plane is 50 degrees. When the clamping piece 8 is pressed by the veneer, the elastic piece and the elastic arc portion deform to offset the expansion of the veneer. When the veneer shrinks due to cold, the elastic piece and the elastic circular arc part lose the extrusion force and reset, so that the fastening pie...

Abstract

The invention belongs to the technical field of fasteners, and relates to an elastic anti-loosening locking mechanism of a wall hanging. It solves the technical problem in the prior art that there is a gap between the thermal expansion and cold contraction of the pendant and the fastener. It carries a sheet and a spring card, and one side of the carrier sheet is provided with at least one locking block, and a connection structure is provided between the locking block and the spring card, and the spring card is provided with a card connection hole, and the spring card can slide the card through the card connection hole. Connected to the locking block, and fixedly connected to the locking block through the connecting structure. Compared with the prior art, the present invention has the advantage of always supporting the facing when the facing expands with heat and contracts with cold.

Description

technical field [0001] The invention belongs to the technical field of building wall panel connectors, and relates to a locking fastener, in particular to an elastic anti-loosening locking mechanism of a wall hanging and its fastener. Background technique [0002] With the implementation of energy-saving measures for external wall insulation in our country, in recent years a kind of thermal insulation integrated board with thermal insulation core + decorative layer has emerged at the historic moment. During the installation process, it is necessary to use installation fasteners. In the prior art, installation fasteners T-shaped openings and butterfly buckles for building curtain walls are usually used. [0003] For example, the Chinese patent document discloses a curtain wall panel dry-hanging installation fastener [CN201810102420.9], which includes a corner bracket fixed on the wall through an anchor, a dry bracket fixed on the corner bracket away from the wall, and a dry b...
