Description

Technical Field

[0001] The utility model relates to the technical field of wall panels, and particularly relates to a quick installation structure for the back of a wall panel. Background Technique

[0002] Wall panels are widely used in modern indoor office buildings or homes. Among them, the wall panels are installed on the surface of a partition frame structure or a wall frame structure for separating indoor spaces or decorating indoor walls. The existing wall panel installation structure can adopt the method of clamping with upper and lower profiles, using grooved top and bottom profiles to clamp the top and bottom edges of the wall panel. Although this installation structure is beautiful and simple, the wall panels need to be inserted into the top and bottom profiles one by one from the side, and the installation is relatively inconvenient. Moreover, in order to avoid loosening, the card slots of the top and bottom profiles are connected to the wall panels relatively tightly, resulting in very laborious installation of the wall panels.

[0003] At present, a Chinese patent with the authorization announcement number of CN113175129A discloses an installation structure of a wall panel, which includes a column, a wall panel, a top beam, a top slot, a top eccentric wheel and a bottom slot; the column is vertically and fixedly arranged; the top beam is horizontally and fixedly arranged at the top of the column, the top slot is hinged to the outside of the top beam, the opening of the top slot faces downward, the inner side wall thereof is rotationally connected with a top eccentric wheel along the axial direction, and the rotation axis of the top eccentric wheel is offset from the center of the top eccentric wheel; the bottom slot is fixed at the bottom of the column, and the opening of the bottom slot faces upward; the top edge of the wall panel is inserted into the top slot, and the top eccentric wheel clamps the back side of the top edge of the wall panel, and the bottom edge of the wall panel is inserted into the bottom slot for supporting and fixing. The present invention can facilitate the installation of the wall panel.

[0004] The above-mentioned existing technical solutions have the following defects: the surface angle of the wall panel cannot be adjusted, and it is easy to cause the problem of boundary drop between multiple panels after installation. Content of the Utility Model

[0005] The purpose of the utility model is to provide a quick installation structure for the back of a wall panel to solve the problems existing in the above-mentioned prior art.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A quick installation structure for the back of a wall panel, including a rectangular bar. Along the length direction of the rectangular bar, a through dovetail groove is arranged at the top of the rectangular bar. At the bottom end of the rectangular bar, a plurality of inserting rods are arranged at equal intervals along the length direction of the rectangular bar. The inserting rods are hinged and fixed to the rectangular bar. One end of the inserting rod close to the rectangular bar is hinged with a threaded rod. A sleeve is screwed on the threaded rod. One end of the sleeve away from the inserting rod is hinged and fixed to the bottom end of the rectangular bar. Symmetrically arranged sliding grooves are provided at the inner top end of the dovetail groove. A plurality of through holes are arranged at equal intervals along the length direction of the dovetail groove inside the dovetail groove. A blocking rod is inserted in the through hole. A baffle plate integrally formed with the blocking rod is arranged at the top of the blocking rod. The baffle plate is inserted and fixed to the inside of the dovetail groove. A plurality of positioning blocks are slidably installed in the dovetail groove. Rectangular grooves are arranged through the tops of the positioning blocks.

[0008] By adopting the above technical scheme, the mutual cooperation of the threaded rod and the sleeve can make the overall length of the threaded rod and the sleeve variable. And through the settings that the threaded rod is hinged with the inserting rod, the sleeve is hinged with the rectangular bar, and the inserting rod is hinged with the rectangular bar, a triangular support structure can be formed. When the overall length of the sleeve and the threaded rod changes and the inserting rod is fixed, the angle of the rectangular bar changes accordingly. Therefore, the angle of the wall panel installed inside the dovetail groove can be changed by adjusting the overall length of the sleeve and the threaded rod, so as to achieve the overall surface flatness between multiple installation plates and avoid the appearance of a drop between the wall panels after installation.

[0009] In a further embodiment, the sleeve includes a fixed cylinder body and an internal threaded cylinder body. The internal threaded cylinder body is rotationally installed inside one end of the fixed cylinder body through a bearing.

[0010] In a further embodiment, a perfusion hole is arranged on the side surface of the fixed cylinder body.

[0011] By adopting the above technical scheme, when the position adjustment of the sleeve and the threaded rod is completed, hot melt adhesive can be perfused into the inside of the sleeve through the perfusion hole to prevent the sleeve and the threaded rod from rotating with each other in the subsequent process.

[0012] In a further embodiment, a plurality of through threaded holes are arranged at the bottom of the dovetail groove of the rectangular bar.

[0013] By adopting the above technical scheme, the up and down angle change of the object inside the dovetail groove can be adjusted by screwing a screw into the threaded rod.

[0014] In a further embodiment, an expansion shell is sleeved at one end of the inserting rod away from the rectangular bar. A chemical expansion agent is filled inside the expansion shell.

[0015] In a further embodiment, a plurality of stress release grooves are arranged at equal intervals along the length direction of the rectangular bar on the rectangular bar.

[0016] By adopting the above technical solution, the internal stress of the rectangular bar cannot be released during thermal expansion and contraction during long-term outdoor use, resulting in plastic deformation of the rectangular bar. The stress release groove can increase the service life of the rectangular bar.

[0017] In a further embodiment, the surface of the rectangular strip is provided with a 0.01 mm anti-corrosion coating, a flow channel penetrating the bottom end of the rectangular strip is provided on one side of the rectangular strip, one end of the flow channel is completely closed, and the other end of the flow channel is completely open, and the flow channel is connected to the bottom of the dovetail groove.

[0018] By adopting the above technical solution, after installation, glue can be poured into the inside of the dovetail groove through the flow channel, and the wall panel and the rectangular strip are adhered to ensure the structural strength and position of the connection.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The overall length of the threaded rod and the sleeve can be changed by the mutual cooperation between the threaded rod and the sleeve, and a triangular support structure can be formed by the hinged connection between the threaded rod and the insertion rod, the hinged connection between the sleeve and the rectangular bar, and the hinged connection between the insertion rod and the rectangular bar. When the overall length of the sleeve and the threaded rod is changed and the insertion rod is fixed, the angle of the rectangular bar changes accordingly. Therefore, the angle of the wall panel installed in the dovetail groove can be changed by adjusting the overall length of the sleeve and the threaded rod, so as to achieve the overall surface leveling between multiple installation panels and avoid the effect of a drop between the wall panels after installation.
