Detailed Description

The invention will be further explained by means of specific embodiments with reference to the drawings.

Example 1: as shown in fig. 1-2, the integrally extruded drop-grade connector includes a clamping head 21, a clamping groove 24 formed by the clamping head 21, a supporting plate 22 disposed below the clamping head 21, a side plate 23 disposed on the same side of the supporting plate 22 as the clamping head 21 and connected to the supporting plate 22 and the clamping head 21, and a hanging head 25 connected to a side surface of the side plate 23, wherein the hanging head 25 is located above the clamping head 21; the clamping head 21 is used for being connected with a groove on the side surface of the top surface decoration plate 3 in a matching mode, the clamping groove 24 is used for being connected with the falling-level decoration plate 4 in a matching mode, after the falling-level decoration plate 4 is inserted into the clamping groove 24 to be connected with the clamping groove 24, the falling-level decoration plate 4 is supported by the supporting plate body 22 in a bearing mode, the hanging head 25 is used for being connected with a base layer component installed on a wall, after the hanging head 25 is connected with the base layer component, the whole falling-level connecting piece is in a hanging state, the base layer component can be a keel with a hanging rod, and can be the hanging rod, and the hanging head is not limited.

In the falling grade connecting piece in the technical scheme, the clamping connector 21 is used for being connected with the top surface decoration plate 3 in a matched mode, the clamping groove 24 is used for being connected with the falling grade decoration plate 4 in a matched mode, namely the falling grade connecting piece is directly connected with the top surface decoration plate 3 and the falling grade decoration plate 4 in a clamping mode.

When the hanging head 25 is deviated in the connecting position on the base member due to various types, or when the depth of the groove on the side surface of the top surface decoration plate 3 is small, the assembly between the top surface decoration plate 3 and the clip head 21 is difficult or even impossible, which requires field replacement of the top surface decoration plate 3 or relocation and installation of a drop connector, the assembly efficiency between the drop connector and the top surface decoration plate 3 is low, for this reason, the clip head 21 includes a clip portion 211, an adjusting portion 212 provided between the clip portion 211 and the side plate body 23 and connected to the clip portion 211, a first connecting portion 213 connecting the adjusting portion 212 and the side plate body 23, the first connecting portion 213 and the side plate body 23 are connected, the adjusting portion 212 has a certain elastic deformation capability and is deformable toward the side plate body 23, and when installed, the top surface decoration plate 3 can be mounted on the clip head 21 from the length direction, in the installation process, the adjusting part 212 is squeezed open and deformed towards the side plate body 23, so that even if the connecting position of the hanging head 25 and the base component is deviated or the depth of the groove on the side surface of the top surface decoration plate 3 is smaller, the groove on the side surface of the top surface decoration plate 3 can be smoothly clamped into the clamping head 21 of the drop-level connecting piece without recalibration and installation of the drop-level connecting piece and replacement of the top surface decoration plate 3, therefore, the fault-tolerant rate of the drop-level connecting piece is high, the assembly efficiency between the site and the top surface decoration plate 3 is high, and after assembly, the adjusting part 212 utilizes the elastic reset performance of the adjusting part per se to enable the clamping head 21 to be tightly pressed on the groove of the top surface decoration plate 3. An included angle between the adjusting portion 212 and the first connecting portion 213 is an acute angle, and an included angle between the adjusting portion 212 and the first connecting portion 211 is an acute angle.

Considering the processing difficulty and the material cost of the integral extrusion, generally speaking, on the premise of satisfying the structural strength, the raw material for extrusion is not very thick, accordingly, the thickness of each position including the clamping portion 211 on the cascade connection member is not very large, and when the clamping portion 211 is assembled with the groove of the top surface decoration plate 3, the head of the clamping portion 211 is easy to collide with the top surface decoration plate 3 and deform, therefore, the head end of the clamping portion 211 is of a bending structure, and the thickness of the clamping portion 211 is increased only at the head end of the clamping portion 211, so that on one hand, the deformation resistance of the clamping portion 211 is increased, and on the other hand, too much material cost is not increased.

Similarly, in the case that the thickness of the suspension head 25 is not very large, the suspension head 25 includes a second connecting portion 251, a third connecting portion 252, and a fourth connecting portion 253 connecting the second connecting portion 251 and the third connecting portion 252, an included angle between the fourth connecting portion 253 and the second connecting portion 251 is an acute angle, and an included angle between the fourth connecting portion 253 and the third connecting portion 252 is an acute angle, so that the suspension head 25 has better structural strength and cannot be easily deformed after bearing the top surface trim 3 and the drop trim 4.

As shown in fig. 3, a plurality of reinforcing grooves 221 are formed in the supporting plate 22, the reinforcing grooves 221 are recessed downward, the reinforcing grooves 221 are arranged along the length direction of the supporting plate 22, the structural strength of the supporting plate 22 is enhanced by the reinforcing grooves 221, and the supporting plate 22 is not easily deformed.

As for the connection manner between the suspension head 25 and the base member, as shown in fig. 4, both side ends of the suspension head 25 in the longitudinal direction respectively extend to the outside of both ends of the side plate body 23 and are formed as hanging portions 26, and the hanging portions 26 can be hung on the base member by hanging means such as hooks and hanging rings. Of course, the suspension head 25 may be attached to the base member by welding.
