Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1 , Figure 2 and Figure 3 As shown;

[0024] An assembled wall connector comprises a first clamping plate 1 and a second clamping plate 2. The second clamping plate 2 comprises a plurality of pressing plates 201 which are buckled in sequence. A threaded sleeve 3 is inlaid in the middle of the pressing plate 201. An extrusion screw 4 is screwed on the middle of the threaded sleeve 3. A limit plate 5 is detachably provided at one end of the extrusion screw 4. A telescopic support frame 6 is passed through the middle of multiple groups of extrusion screws 4. A slide groove 7 for accommodating the limit plate 5 is provided in the middle of one side of the first clamping plate 1. A limit plate 8 is inlaid on the top of the slide groove 7. A guide groove 9 which matches the extrusion screw 4 is provided on the limit plate 8.

[0025] It should be noted that: in this embodiment, heat insulating materials can be provided on the side where the first clamping plate 1 and the second clamping plate 2 are close to each other and inside the telescopic support frame 6, so as to avoid the generation of cold bridges between metal molded parts.

[0026] In this embodiment: by rotating the extrusion screw 4, the first clamping plate 1 and the second clamping plate 2 can be driven to approach each other, so as to clamp the wall panel. The telescopic support frame 6 can play a good supporting role, and by setting the second clamping plate 2 as a multi-piece splicing type, the purpose of block adjustment can be achieved, so as to fully fit the wall panels at different thickness positions. At the same time, this embodiment is easy to disassemble and assemble, thereby saving transportation space.

[0027] In an optional embodiment, one end of two groups of pressure plates 201 close to each other are respectively provided with a rectangular groove and a rectangular protrusion that fit together, and the depth of the rectangular groove is equal to the thickness of the rectangular protrusion. One end of the two groups of pressure plates 201 close to each other are respectively provided with a limiting column 202 and a limiting groove 203 that fit together.

[0028] In this embodiment: the surfaces of multiple groups of pressure plates 201 are flush after being buckled together, and the limiting column 202 slides in the limiting groove 203 to prevent the multiple groups of pressure plates 201 from being separated from each other, thereby ensuring the integrity of the second clamping plate 2 and preventing the pressure plate 201 from rotating when the extrusion screw 4 rotates.

[0029] In an optional embodiment, the telescopic support frame 6 includes a first sleeve 601 and a second sleeve 602 which are sleeved on each other, the extrusion screw 4 passes through the first sleeve 601 and the second sleeve 602, and a compression spring 603 is provided on the outside of the extrusion screw 4 and between the first sleeve 601 and the second sleeve 602.

[0030] In this embodiment: the compression spring 603 drives the first sleeve 601 and the second sleeve 602 to separate from each other, and the avoidance hole diameter on the first sleeve 601 is smaller than the diameter of the limit plate 5, thereby preventing the first sleeve 601 and the second sleeve 602 from detaching from the extrusion screw 4.

[0031] like Figure 4 and Figure 5 As shown;

[0032] In an optional embodiment, the guide groove 9 includes an arcuate groove 901 and a straight groove 902 which are connected to each other, the diameter of the arcuate groove 901 is larger than the diameter of the limiting plate 5, the width of the straight groove 902 is smaller than the diameter of the limiting plate 5 and equal to the diameter of the extrusion screw 4, and multiple groups of slide grooves 7 are parallel to each other, one end of the slide groove 7 extends to the middle of the first clamping plate 1, and the width of the slide groove 7 is larger than the diameter of the limiting plate 5.

[0033] In this embodiment: the extrusion screw 4 drives the limiting plate 5 at one end thereof to enter the slide groove 7 through the arc groove 901 and slide along the arc groove 901, so that it is limited in the slide groove 7 by the limiting plate. After the wall panel abuts against the first sleeve 601 and the second sleeve 602, the extrusion screw 4 can be prevented from leaving the slide groove 7. In this way, the extrusion screw 4 can be ensured to rotate in the slide groove 7 by the limiting plate 5, thereby realizing the mutual approach between the pressure plate 201 and the first clamping plate 1.

[0034] The working principle and use process of the utility model are as follows: first, multiple groups of pressing plates 201 are spliced ​​in sequence to form a complete second clamping plate 2, the extrusion screw 4 is screwed into the threaded sleeve 3, the first sleeve 601 and the second sleeve 602 are mutually sleeved and then inserted into the extrusion screw 4, and then the limit plate 5 is fixed to the end of the extrusion screw 4, the limit plate 5 is aligned with the slide groove 7, and the limit plate 5 is extended into the slide groove 7 through the arc groove 901, and then the extrusion screw 4 is pushed to make it enter the end of the arc groove 901, and at the same time, the two groups of wall panels are placed on both sides of the first sleeve 601 and the second sleeve 602 respectively and kept in contact with the inner wall of the first clamping plate 1, at this time, the extrusion screws 4 at both ends are rotated first and then the extrusion screw 4 in the middle is rotated, and the extrusion screw 4 drives the pressing plate 201 to approach the first clamping plate 1, so as to clamp and fix the wall panels.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
