[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: a prefabricated and assembled thermal insulation and sound insulation wall, including a wall body 1. A dovetail block 2 is fixedly connected to the top end of the outer wall of the wall body 1. A plurality of bolt holes are opened at the bottom end of the wall body 1 and correspond to the bolt holes opened on the surface of the dovetail block 2. Thus, when the dovetail block 2 enters the inner wall of the dovetail groove at the bottom end of the wall body 1, bolts can be used to reinforce and lock the two, which is the prior art. The thermal insulation component 3 is detachably installed on the inner wall of the wall body 1, and the positioning component 4 is arranged on the inner wall at the bottom end of the wall body 1.

[0034] Referring to Figures 2 - 3, the heat insulation component 3 includes a mounting block 31. The left outer wall of the mounting block 31 is in contact with the right outer wall of the wall body 1. A cavity is provided in the inner wall of the wall body 1. The heat insulation board 32 is slidably connected to the inner wall of the cavity of the wall body 1. The heat insulation board 32 is a heat insulation layer in the prior art, and the heat insulation board 32 can be driven by the mounting block 31 to be detachable. Thus, when the outside of the wall body 1 is damaged, the heat insulation board 32 can be taken out for recycling. A dovetail groove is provided in the inner wall of the bottom end of the wall body 1. The outer wall of the dovetail block 2 corresponds to the inner wall of the dovetail groove at the bottom end of the wall body 1. The two are corresponding to each other. Thus, when two wall bodies 1 are spliced, the dovetail block 2 can slide into the inner wall of the bottom end of the previous wall body 1. The left outer wall of the mounting block 31 is fixedly connected with the heat insulation board 32. A rotating block 33 penetrates through and is rotatably connected to the center of the inner wall of the mounting block 31. A wedge block 36 is elastically connected to the inner wall of the mounting block 31 through a limiting spring 35.

[0035] Refer to Figures 2 - 3 , two sets of clamping grooves are provided in the inner wall of the wall body 1. The wedge block 36 is clamped with the inner wall of the clamping groove. The clamping between the two fixes the position of the mounting block 31 driving the heat insulation board 32 on the inner wall of the wall body 1. The wedge block 36 penetrates through and is slidably connected to the inner wall of the mounting block 31. One end of the limiting spring 35 is fixedly connected to the side wall at the top end of the wedge block 36, and the other end of the limiting spring 35 is fixedly connected to the inner side wall of the mounting block 31. The function of the limiting spring 35 is to automatically reset the wedge block 36 when the inclined surface of the wedge block 36 is squeezed and moves. One end of the connecting rope 34 away from the rotating block 33 is rotatably hinged to the top end of the outer wall of the wedge block 36. When the rotating block 33 rotates, it will drive the two connecting ropes 34 to be wound on its surface, so as to pull the two wedge blocks 36 to move inwards synchronously. Two connecting ropes 34 are wound around the surface of the rotating block 33.

[0036] Refer to Figures 3 - 5The positioning assembly 4 includes a positioning block 42, which is elastically connected to the inner wall at the bottom end of the wall 1 through a return spring 41, one end of the return spring 41 is fixedly connected to the top of the outer wall of the positioning block 42, and the other end of the return spring 41 is fixedly connected to the bottom end of the inner wall of the wall 1. The function of the return spring 41 is to automatically reset the position of the positioning block 42 after being squeezed and moved when the inclined surface of the positioning block 42 is squeezed and moved by the dovetail block 2. The positioning block 42 is slidably connected to the inner wall at the bottom end of the wall 1, and the connecting block 43 penetrates and is slidably connected to the inner wall at the bottom end of the wall 1. When disassembling the two groups of wall bodies 1 after being combined, the positioning block 42 can be driven to rise by toggling the connecting block 43, so that the bottom end of the positioning block 42 can be disengaged from the clamping connection with the slot of the dovetail block 2, so that the two groups of wall bodies 1 can be separated and taken out. The outer wall of the positioning block 42 is fixedly connected to the connecting block 43, and the inner wall of the top of the dovetail block 2 is provided with a clamping slot. The bottom end of the outer wall of the positioning block 42 is clamped with the inner wall of the slot. The clamping connection between the two allows the dovetail block 2 to slide into the position of the inner wall of the wall 1 for preliminary fixation, so that it is convenient for the staff to rotate the bolts to install it.

[0037] Working principle: When splicing and fixing two groups of walls 1, first slide the dovetail block 2 of the upper group of walls 1 into the inner wall of the dovetail groove at the bottom end of the next group of walls 1. The outer wall of the dovetail block 2 will squeeze the inclined surface of the positioning block 42 of the positioning assembly 4, so that the positioning block 42 compresses the return spring 41 and moves. The dovetail block 2 continues to slide until the bottom end of the positioning block 42 is stuck in the groove of the inner wall of the top end of the dovetail block 2, so as to perform a quick preliminary fixation. At this time, it is convenient for the staff to rotate the bolt to penetrate the bottom end of the wall 1 and reinforce and lock it with the dovetail block 2.

[0038] When the exterior of the wall 1 is damaged and the insulation board 32 inside needs to be disassembled and taken out, the rotating block 33 is rotated to reel in the upper and lower sets of connecting ropes 34. At the same time, the upper and lower sets of connecting ropes 34 will pull the wedge block 36 inward to release the card slot connection of the current position of the wall 1, and the insulation board 32 can be taken out for recycling. When the two sets of walls 1 are to be disassembled, the connecting block 43 is moved to drive the positioning block 42 to rise, so that the bottom end thereof is disengaged from the card slot connection of the dovetail block 2, and the two sets of walls 1 can be separated and taken out.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
