Description

Technical Field

[0001] The utility model relates to the technical field of hidden screw connection between wall plates and keels, in particular to a connection structure for plates and keels. Background Art

[0002] At present, during the installation of walls and plates, the connection is generally carried out in the following two ways. One is that bolts pass through the plates and are fixed to the wall. However, in this installation structure, since the bolts penetrate the plates, on-site processing of the plates is required, and on-site processing is likely to cause the plates to crack. The other is to use chemical glue to connect the plates and the wall. However, in this installation structure, it takes time to wait for the glue to cure, and certain safety problems will occur after the glue ages. The fixed installation efficiency of the above methods is low, the safety performance is not guaranteed, and it is impossible to ensure that the spacing between each installed plate is the same, resulting in a serious height difference between the plates after installation, which greatly affects the aesthetics of the decoration.

[0003] Therefore, based on the above technical problems, this application specifically proposes a more efficient and safe connection structure for plates and keels. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a connection structure for plates and keels that is more stable and can be installed more quickly.

[0005] To achieve the above purpose, a connection structure for plates and keels provided by the utility model includes a keel between the wall and the plate. Among them, the keel is connected to the wall through pre-set fixed bolts. It is characterized in that it further includes a connection fastener fixedly connected to the plate and capable of being hung and fitted with the keel. Among them, the connection fastener includes an expansion sleeve, a support rod, a hanging rod, and a locking ring. A plurality of annularly arranged support claws are formed at the end of the expansion sleeve. One end of the support rod is threadedly nested with the expansion sleeve so that the end of the support rod touches each support claw and pushes it outward to expand. The hanging rod is formed with a fixing screw hole extending along its axial direction for threaded cooperation with the other end of the support rod. The locking ring is threadedly sleeved on the outer peripheral surface of the hanging rod. The hanging rod is hung and fitted with a pre-opened hanging hole on the keel. After the hanging is completed, the keel is clamped by screwing the locking ring and cooperating with a convex platform pre-formed at the end of the hanging rod.

[0006] Furthermore, the keel further includes a first connection surface and a second connection surface. The first connection surface is connected to the wall, and the second connection surface is connected to the plate.

[0007] Further, a fixing hole which penetrates through and is used for placing the fixing bolt is formed on the first connecting surface; a hanging hole which penetrates through and is used for hanging and installing the connecting fastener is formed on the second connecting surface.

[0008] Further, the hanging hole is in an inverted gourd shape with a large upper caliber part and a small lower caliber part. The diameter of the second boss of the hanging rod is slightly smaller than the diameter of the upper caliber part of the hanging hole, and the diameter of the second boss of the hanging rod is larger than the diameter of the lower caliber part of the hanging hole.

[0009] Further, an internal hexagonal groove is provided inside the support rod, and the outer peripheral surfaces of the support rod and the hanging rod are both provided with threads; the inside of the expansion sleeve is provided with threads.

[0010] Further, after the expansion sleeve is pre-installed on the plate, the external thread of the support rod is matched with the internal teeth inside the expansion sleeve, so that each support claw at the end of the expansion sleeve is pushed outwards.

[0011] Further, a fixing screw hole which extends along the axial direction of the hanging rod and is used for threadedly matching with the other end of the support rod is formed at one end of the hanging rod. A second boss is pre-formed at the other end of the hanging rod, and the second boss is matched with the lock ring to clamp the keel.

[0012] The beneficial effects of the present utility model adopting the above scheme are as follows:

[0013] 1) Convenient installation: By designing the connecting fastener, the installation method between the plate member and the keel is improved and optimized. When installing the plate, it is only necessary to hang the connecting fastener pre-installed on the plate on the keel and lock and fix it. This design realizes the quick hanging of the plate and the keel, and is easier to assemble.

[0014] 2) Aesthetic property: By installing the connecting fastener inside the plate, the outer surface of the plate is kept intact, improving the overall aesthetic property.

[0015] 3) Safety: Without using chemical glue, through the tight fit between the connecting fastener and the hanging hole of the keel, the plate can be firmly hung on the keel after installation, ensuring the safety of the connection. Description of the Drawings
