DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-7 , the present invention provides a technical solution:

[0024] In order to improve the connection efficiency of the device, an insulation board assembly is proposed, including: a base frame 1, a first fixing mechanism 2, a second fixing mechanism 3, and an insulation board 4. The base frame 1 is in a "+" shape, and a lifting ear 103 is fixedly arranged on the connecting layer 102 in the base frame 1. A screw hole is arranged on the lifting ear 103. The lifting ear 103 is in contact with and connected to the wall. The base frame 1 is fixed to the wall through the lifting ear 103 and the fixing screws.

[0025] The base frame 1 is divided into two layers, one of which is a hook layer 101, and the other is a connecting layer 102. The displacement rod 204 in the first fixing mechanism 2 is slidably installed in the hook layer 101, and the hook 212 is movably installed on the displacement rod 204. The insulation board 4 is preliminarily connected through the hook 212. A plurality of expansion screws 308 in the second fixing mechanism 3 are rotatably installed in the connecting layer 102, and the secondary connection between the base frame 1 and the insulation board 4 is realized through the expansion screws 308. Four protrusions 309 are fixedly set on the insulation board 4, and screw holes corresponding to the expansion screws 308 are set between two protrusions 309. The thickness of the insulation board 4 is the same as that of the hook layer 101.

[0026] Slide rails 1011 are arranged on both sides of the hook layer 101 in the horizontal direction, and the heat preservation board 4 is provided with second sliding blocks 1012 corresponding to the slide rails 1011 .

[0027] First, slide the second slider 1012 of the insulation board 4 into the slide rail 1011 on the connecting layer 102 to complete the preliminary fixation between the insulation board 4 and the base frame 1. In the preliminary fixed state, the position between the insulation board 4 and the base frame 1 is: the lower end face of the insulation board 4 is in contact and connected with the upper end face of the connecting layer 102, the side face of the insulation board 4 is in contact and connected with the side face of the hook layer 101, the protrusion 309 corresponds to the hook 212, and the screw hole corresponds to the expansion screw 308.

[0028] A rotating rod 205 is fixedly arranged at the center of the rotating disk 201 , one end of the rotating rod 205 extends out of the base frame 1 , a slot is arranged on the rotating rod 205 , a detachable connecting pin is arranged on the base frame 1 , and the pin contacts and connects with the slot on the rotating rod 205 .

[0029] By inserting the latch into the rotating rod 205 , the free rotation of the rotating rod 205 can be restricted, thereby restricting the movement of the displacement rod 204 and the two racks.

[0030] The rotating disk 201 is rotated by manually twisting the rotating rod 205 .

[0031] The first fixing mechanism 2 comprises: a rotating disk 201, a first connecting rod 202, and a displacement rod 204. The rotating disk 201 is rotatably installed in the base frame 1. One end of the rotating disk 201 is hinged to one end of four first connecting rods 202. The other end of the first connecting rod 202 is hinged to one end of the second connecting rod 203. The other end of the second connecting rod 203 is hinged to one end of the displacement rod 204. The displacement rod 204 is slidably installed in the hook layer 101 on the base frame 1.

[0032] The maximum rotation distance of the turntable 201 is a quarter of a turn.

[0033] When the turntable 201 rotates, the connecting end of the first connecting rod 202 and the turntable 201 starts to rotate, and the overall length of the first connecting rod 202 does not change, so the first connecting rod 202 is displaced, and the other end of the first connecting rod 202 pushes the second connecting rod 203 to move, and the second connecting rod 203 pushes the displacement rod 204 to slide in the hook layer 101. This mechanism is similar to the crank slider technology in the prior art.

[0034] A slide groove 207 is arranged on the surface of the displacement rod 204, and the slide groove 207 is in an oblique line shape. A first slider 208 is slidably installed in the slide groove 207, and the first slider 208 is fixedly connected to one end of a third connecting rod 209, and the other end of the third connecting rod 209 is fixedly connected to a bottom plate 211. A first spring 210 is sleeved on the surface of the third connecting rod 209, and one end of the first spring 210 is fixedly connected to the hook layer 101, and the other end is fixedly connected to the bottom plate 211. One end of a hook 212 is hingedly connected to both ends of the bottom plate 211. There are two hooks 212, and the middle parts of the two hooks 212 are hinged. The other end of the hook 212 is in contact with and connected to the protrusion 309 on the insulation board 4. A strip groove is arranged on the surface of the hook 212, and one end of the top rod 206 is slidably installed in the strip groove, and the other end of the top rod 206 is fixedly connected to the hook layer 101.

[0035] When the displacement rod 204 moves, the position of the slide groove 207 also changes in the same direction. In the initial state, the first slider 208 is located at the top of the slide groove 207. As the slide groove 207 moves, the surface of the slide groove 207 applies pressure to the first slider 208, so that the first slider 208 moves to the bottom of the slide groove 207.

[0036] When the first slider 208 moves to the bottom of the slide groove 207, the third connecting rod 209 moves in the same direction as the first slider 208. The third connecting rod 209 pushes the bottom plate 211 to move away from the displacement rod 204 and gradually extends out of the hook layer 101. The first spring 210 extends accordingly, and the bottom plate 211 pushes the two hooks 212 to move away from the displacement rod 204. The strip grooves on the surfaces of the hooks 212 also move, but the position of the top rod 206 does not change. Therefore, the strip grooves on the surfaces of the hooks 212 will be subjected to the thrust from the top rod 206, and the two hooks 212 will then rotate and contact and connect with the protrusions 309, completing the preliminary connection of the insulation board 4.

[0037] After the hook 212 is connected to the protrusion 309 , the hook 212 is subjected to the pulling force from the first spring 210 . Under the pulling force of the first spring 210 , the connection between the hook 212 and the protrusion 309 is more stable.

[0038] After the hook 212 is connected to the protrusion 309, the cover plate 310 is fixed to the base frame 1 by fixing screws, and the cover plate 310 covers the protrusion 309.

[0039] In order to improve the connection stability of the device, a heat preservation board assembly is proposed, wherein the second fixing mechanism 3 includes: a first gear 301, a second gear 302, and an expansion screw 308. One side of the first gear 301 is fixedly connected to the lower end surface of the turntable 201, the first gear 301 is meshedly connected to the first rack 303, the upper end surface of the second gear 302 is fixedly connected to the lower end surface of the first gear 301, the second gear 302 is meshedly connected to the second rack 304, the first rack 303 is slidably installed in the connection layer 102, the second rack 304 is slidably installed in the connection layer 102, the first rack 303 and the second rack 304 are not on the same plane, do not interfere with each other, and the first rack 303 and the second rack 304 are in a "+" shape;

[0040] The rotation of the first gear 301 will drive the first rack 303 to slide in the connecting layer 102, and the rotation of the second gear 302 will drive the second rack 304 to slide in the connecting layer 102. Since the first gear 301 is fixedly connected to the second gear 302, the first gear 301 and the second gear 302 rotate at the same time, and the first rack 303 and the second rack 304 slide at the same time in the connecting layer 102.

[0041] One side of the first rack 303 is meshed with eight third gears 305, and there are 16 third gears 305 in total. The second rack 304 is meshed with eight third gears 305. The third gears 305 are rotatably installed in the connecting layer 102 and are arranged on both sides of the first rack 303. One side of the third gear 305 is fixedly connected to a limit plate 306, and the limit plate 306 is fixedly connected to a threaded rod 307. A thread corresponding to the same is arranged on the connecting layer 102. The threaded rod 307 is threadedly connected to the upper surface of the connecting layer 102, and the upper end of the threaded rod 307 is fixedly connected to an expansion screw 308. An expansion screw 308 installation area is arranged in the connecting layer 102, and screw holes corresponding to the expansion screws 308 are arranged on the insulation board 4.

[0042] The first rack 303 and the second rack 304 slide and drive the third gear 305 to rotate. The width of the third gear 305 is twice the width of the first rack 303 and the second rack 304. The rotation of the third gear 305 drives the limit plate 306 to rotate. The limit plate 306 prevents the first rack 303 and the second rack 304 from disengaging from the third gear 305. The rotation of the limit plate 306 drives the threaded rod 307 and the expansion screw 308 to rotate. The threaded rod 307 is threadedly connected to the upper surface of the connecting layer 102, so the threaded rod 307 will move upward when it rotates, and the third gear 305 will also move upward when it rotates. Since the width of the third gear 305 is greater than the width of the first rack 303 and the second rack 304, the third gear 305 will not disengage. When the expansion screw 308 completely rises to the outside of the connecting layer 102 and enters the screw hole of the insulation board 4, the expansion screw 308 expands to complete the secondary fixed connection between the insulation board 4 and the base frame 1.

[0043] The expansion screw 308 adopts the existing technology.

[0044] Working principle:

[0045] First, fix the base frame 1 on the wall through the lifting ear 103, and one side of the connecting layer 102 of the base frame 1 is in contact with the wall, and slide the second slider 1012 of the insulation board 4 into the slide rail 1011 on the connecting layer 102 to complete the preliminary fixation between the insulation board 4 and the base frame 1. In the preliminary fixed state, the position between the insulation board 4 and the base frame 1 is: the lower end surface of the insulation board 4 is in contact and connected with the upper end surface of the connecting layer 102, and the side surface of the insulation board 4 is in contact and connected with the side surface of the hook layer 101.

[0046] At this time, the protrusions 309 on the four insulation boards 4 correspond to the hooks 212 on the hook layer 101, and the screw holes are aligned with the expansion screws 308. Then, the turntable 201 is rotated by the rotating rod 205. The rotation of the turntable 201 causes the hooks 212 to clamp the protrusions 309. While the hooks 212 clamp the protrusions 309, the movement of the first rack 303 and the second rack 304 causes the expansion screws 308 to move upward. When the expansion screws 308 completely rise to the outside of the connecting layer 102 and enter the screw holes of the insulation boards 4, the expansion screws 308 expand to complete the connection between the base frame 1 and the insulation boards 4. The pin is inserted into the rotating rod 205 to fix the rotating rod 205, thereby fixing the position of the turntable 201 so that it does not rotate freely.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
