[0020] like Figure 1-4As shown, a wall connector comprises a rod body 1 and a chuck 2 arranged at both ends of the rod body 1, wherein the chuck 2 comprises a disc body 3, a first rod hole 4 arranged in the middle of the disc body 3, a holder 5 arranged on the outer end surface of the disc body 3 and protruding outward, a second rod hole 6 arranged in the middle of the holder 5 and corresponding to the first rod hole 4, a clamping platform 7 arranged on the outer end surface of the holder 5 and protruding outward, and a locking cap 8 arranged on the outer side of the clamping platform 7, wherein at least two clamping platforms 7 are arranged at intervals around the second rod hole 6, and the two ends of the rod body 1 pass through the first rod hole 4 and the second rod hole 6 in sequence and are fixed to the locking cap 8, and the diameter of the locking cap 8 is larger than the inner diameter of the clamping platform 7 after the annular array.

[0021] The rod body 1 is a long rod-shaped structure made of metal material with high strength. The disk body 3 is a disk-shaped structure made of non-metallic material, which can effectively avoid cold bridges. There is no need to cover the rod body 1 with a material with low thermal conductivity, which saves costs and reduces processing difficulty. The outer diameter of the locking cap 8 is larger than the inner diameter of the circular array of the card platform 7, so that the locking cap 8 will not be embedded in the inner side of the card platform 7 after being locked, ensuring that the position of the locking cap 8 will not be offset. The locking cap 8 at least one end of the rod body 1 is made of non-metallic material.

[0022] The end of the rod body 1 is inserted into the first rod hole 4, and after passing through the second rod hole 6, it is fixed with the locking cap 8. The fixing method is not limited. The position between the clamping platform 7 can clamp the wire mesh frame in, which plays a positioning role. After the locking cap 8 is fixed to the rod body 1, the wire mesh frame can be limited on the clamping base 5 to fix the wire mesh frame. The wire mesh frame can be positioned first by the clamping base 7 on the clamping base 5, and then the wire mesh frame is clamped and fixed by the locking cap 8 and the rod body 1. The structure is simple, the operation is convenient, the construction efficiency is improved, and the design has low processing difficulty and low cost.

[0023] like Figure 3 As shown, both ends of the rod body 1 are provided with external threads, and the middle of the locking cap 8 is provided with an internal threaded blind hole 9. Both ends of the rod body 1 pass through the first rod hole 4 and the second rod hole 6 in sequence and are threadedly connected with the locking cap 8.

[0024] One of the fixing methods of the locking cap 8 and the rod body 1 is to realize threaded connection by machining an internal threaded blind hole 9 on the locking cap 8 and an external thread on the rod body 1. The disk body 3 has good integrity and will not expose the end of the rod body 1, effectively avoiding cold bridges.

[0025] like Figure 4 As shown, a slot is provided in the middle of the lock cap 8 and a nut 10 is embedded in the slot. Both ends of the rod body 1 pass through the first rod hole 4 and the second rod hole 6 in sequence and are threadedly connected with the nut 10 in the lock cap 8.

[0026] Another way to fix the lock cap 8 and the rod body 1 is to use a slot to insert the nut 10 instead of directly processing the threaded hole on the lock cap 8. The nut 10 and the slot are embedded in each other, and the thread 10 will not rotate. The assembly is simple, the processing difficulty is reduced, and the cold bridge is effectively avoided.

[0027] like Figure 4 As shown, the inner wall of the slot and the outer periphery of the nut 10 are both polygonal structures.

[0028] The inner wall of the slot is adapted to the outer periphery of the nut 10 , and the polygonal structure ensures that the nut 10 will not rotate in the slot.

[0029] like Figure 1-2 As shown, the clamping platform 7 is an arc-shaped structure and is provided in four pieces. The four clamping platforms 7 are arranged in a circular array around the second rod hole 6 and are spaced apart.

[0030] The four clamping platforms 7 can provide a higher strength and more accurate positioning when the wire mesh frame is clamped in.

[0031] like Figure 1-2 As shown, a protruding reinforcing rib 11 is provided on the outer end surface of the disc body 3 , and a plurality of reinforcing ribs 11 are arranged in a circular array around the first rod hole 4 , and the inner ends of the plurality of reinforcing ribs 11 are all fixed to the holder 5 .

[0032] The multiple reinforcing ribs 11 further improve the strength of the plate body 3, and the holder 5 is fixed to the reinforcing ribs 11, so the distance between the steel wire mesh and the insulation layer can be controlled by controlling the sizes of the reinforcing ribs 11 and the holder 5.

[0033] like Figure 1-2 As shown, the reinforcing rib 11 is in a right-angled triangle structure, and one end of the right-angled side faces the first rod hole 4 .

[0034] The shape of the reinforcing rib 11 is further defined, and the strength and aesthetics are further improved.

[0035] like Figure 1-2 As shown, a hollow structure is provided between the reinforcing ribs 11 on the plate body 3 .

[0036] When the strength of the plate body 3 meets the requirements, adding a hollow structure can reduce the material consumption and reduce the dead weight.

[0037] like Figure 3-4 As shown, the locking cap 8 and the card table 7 are provided with anti-backward protrusions 12 at corresponding positions, and the anti-backward protrusion 12 is provided with an inclined surface at one end facing the card table 7, and the end of the inclined surface facing the clockwise direction is the lower end.

[0038] The anti-backward protrusion 12 can be stuck between adjacent card platforms 7 after the lock cap 8 is tightened, effectively preventing the lock cap 8 from backing up. In this design, a right-angled triangle anti-backward protrusion 12 is adopted, and its hypotenuse faces clockwise, which does not hinder the tightening of the lock cap 8.
