[0002] When constructing a house in an area with a low temperature, an insulation unit is usually installed on the outer wall of the house to achieve the effect of insulation of the building. When installing the insulation unit, a connection device is mainly used to fix it with a protective layer such as concrete;

[0003] For example, in the prior art, a patent document with publication number CN216276238U provides a connection device for an ultra-low energy consumption integrated thermal insulation prefabricated multi-story house; the device uses structures such as springs, permanent magnets, sleeves, and connecting pipes, so that when the thickness of the thermal insulation unit changes, the device can still position the thermal insulation unit: however, the device is limited by the length of the sleeve and the connecting pipe, so that the thickness selection range of the thermal insulation unit can only be within a specific range, and when the number of thermal insulation units changes, the thickness of the thermal insulation unit will change significantly, which makes it difficult for this connection device with a limited adjustment range to continue to fix the thermal insulation unit. For this reason, we propose a connection device for an ultra-low energy consumption integrated thermal insulation prefabricated multi-story house. Utility Model Content

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] See also Figure 1-4 The utility model provides a technical solution: a connection device for an ultra-low energy consumption integrated thermal insulation assembled multi-story house, comprising a plurality of thermal insulation units 1 plugged into each other, an outer protective layer 11 and an inner protective layer 12 are respectively plugged into and installed on the front and rear sides of the thermal insulation unit 1, a threaded groove 13 is provided on the rear side of the outer protective layer 11, and threaded holes 14 that are connected to the threaded groove 13 are provided in the middle of the inner protective layer 12 and the plurality of thermal insulation units 1, threaded rods 15 that are threadably matched with the threaded holes 14 and the threaded grooves 13 are rotatably installed in the plurality of threaded holes 14, a movable rod 21 is plugged into and installed in the threaded rod 15, a positioning pin 22 is fixedly installed on the threaded groove 13 and the rear end of the movable rod 21, and a positioning socket 23 that is plugged into the positioning pin 22 is provided at the front end of the movable rod 21.

[0024] Working principle: When installing the heat preservation unit 1, multiple heat preservation units 1 and inner protective layer 12 can be installed on the rear side of the outer protective layer 11 in sequence by plugging and matching between the heat preservation units 1 and between the heat preservation units 1 and the outer protective layer 11 and the inner protective layer 12;

[0025] When adjacent heat preservation units 1, heat preservation units 1, outer protective layer 11 and inner protective layer 12 are fitted together, the threaded rod 15 is rotated inside to move forward, so that it can be threadedly connected with the thread groove 13 or the rear end of the front threaded hole 14, so that multiple heat preservation units 1 and outer protective layer 11 can be positioned in sequence at the rear end of the inner protective layer 12 to complete the installation of the heat preservation unit 1;

[0026] Among them, after the threaded rod 15 is rotated forward, the movable rod 21 can be pushed forward inside the threaded rod 15, so that the positioning hole 23 at the front end of the movable rod 21 and the positioning pin 22 inside the threaded groove 13 or at the rear end of the front movable rod 21 are plugged into each other, so that the threaded rod 15 can be positioned in the threaded hole 14 to ensure the connection effect between the insulation unit 1 and the outer protective layer 11 and the inner protective layer 12.

[0027] Example 2

[0028] An annular slot 16 is provided on the outer protective layer 11 and the rear end surface of each insulation unit 1, and an annular plug plate 17 plugged into the annular slot 16 is fixedly installed on the inner protective layer 12 and the front end surface of each insulation unit 1. The annular slot 16 and the annular plug plate 17 are arranged on the periphery of the threaded hole 14, and the annular slot 16 and the annular plug plate 17 are arranged in an angular ring shape.

[0029] By plugging and fitting the annular slot 16 and the annular plug plate 17, and because the annular slot 16 and the annular plug plate 17 are arranged in an angular ring shape, the heat preservation unit 1 and the inner protective layer 12 can be positioned when they are installed, so that when the threaded rod 15 is rotated, the rotating threaded rod 15 can be prevented from driving the heat preservation unit 1 and the inner protective layer 12 to rotate with it.

[0030] Example 3

[0031] An inserting cavity 2 is provided in the threaded rod 15, a movable rod 21 is provided in the inserting cavity 2, and a spring 28 is fixedly installed between the inserting cavity 2 and the movable rod 21, a sliding groove 24 is provided on the inner wall of the inserting cavity 2, a slider 25 is fixedly installed on the periphery of the movable rod 21, the slider 25 is provided in the sliding groove 24, a sliding rod 26 is fixedly installed in the sliding groove 24, a sliding hole 27 for slidingly cooperating with the sliding rod 26 is provided in the slider 25, a spring 28 is fixed between the sliding groove 24 and the slider 25, and the spring 28 is sleeved on the periphery of the sliding rod 26.

[0032] The inserting cavity 2 is provided to increase the installation and activity space of the movable rod 21, and the sliding cooperation between the sliding rod 26 and the sliding hole 27 can limit the movement direction of the movable rod 21 in the inserting cavity 2, so that when the positioning plug hole 23 and the positioning pin 22 are plugged into each other, the threaded rod 15 can be positioned in the threaded hole 14;

[0033] Among them, the positioning pin 22 at the rear end of the movable rod 21 is set in a prismatic shape, so that when the insulation unit 1 and the inner protective layer 12 need to be installed or disassembled, the threaded rod 15 can be rotated in the threaded hole 14 through the positioning pin 22 to complete the installation or disassembly of the insulation unit 1 and the inner protective layer 12. A spring 28 is set. When the positioning pin 22 is released, the movable rod 21 can be driven to move forward through its deformation recovery effect, thereby ensuring that the positioning hole 23 can be plugged into the positioning pin 22 at its front end.

[0034] Example 4

[0035] A sealing cover 3 threadably matched with the threaded hole 14 is disposed at the rear side of the inner protective layer 12 , and a groove 31 matching with the positioning pin 22 is formed at the front end of the sealing cover 3 .

[0036] A sealing cover 3 is provided, and the sealing cover 3 can be installed through the threaded cooperation between the sealing cover 3 and the threaded hole 14 on the rear side of the inner protective layer 12, so as to achieve the effect of sealing the threaded hole 14, and the threaded hole 14 and the threaded rod 15 can be protected.
