[0020] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to be able to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] See also Figures 1 to 3 , the figure shows the preferred structure of the heat preservation nail in this embodiment. As shown in the figure, the heat preservation nail includes: a sleeve 1 and a locking mechanism 2. Among them, both ends of the sleeve 1 are open ends. The first end ( Figure 1 The upper end shown in the figure is used to be placed outside the outer wall of the structure 3, the sleeve 1 is inserted into the drilled hole of the structure 3, and the locking mechanism 2 is arranged at the second end ( Figure 1 The lower end shown in the figure), and the locking mechanism 2 is locked with the structure 3, so that the insulation nail and the structure 3 are relatively fixed, thereby realizing the installation of the insulation nail.

[0022] Specifically, the structure 3 is provided with a borehole, the first end of the sleeve 1 is located outside the borehole of the structure 3, and the second end of the sleeve 1 can be placed inside the borehole, in which case the locking structure is at least partially placed inside the borehole. Alternatively, the structure 3 has a certain thickness, the borehole runs through the thickness direction of the structure 3, and the second end of the sleeve 1 is placed at the edge of the structure 3, in which case the first end of the sleeve 1 and the locking mechanism 2 are respectively placed on both sides of the thickness direction of the structure 3. The position of the second end of the sleeve 1 is determined according to the structural style and thickness of the structure 3, and this embodiment does not impose any restrictions on this.

[0023] It can be seen that in the present embodiment, the sleeve 1 is passed through the drilled hole of the structure 3, and the locking mechanism 2 is arranged at the second end of the sleeve 1 and is locked with the structure 3, so that the insulation nail and the structure 3 are relatively fixed, thereby realizing the installation of the insulation nail. Moreover, the locking mechanism 2 is connected to the sleeve 1 as a whole, which is convenient for installing the insulation nail and can also prevent the insulation nail from expanding prematurely, thereby improving the pull-out resistance and overall stability of the insulation nail, and solving the problem in the prior art that the insulation nail is easily expanded due to the combination of the insulation nail and the plastic cap in advance during the installation of the insulation nail.

[0024] See also Figures 1 to 3 In the above embodiment, the locking mechanism 2 includes: a driving member 21 and a locking assembly. The locking assembly is arranged at the second end of the sleeve 1. The driving member 21 is inserted into the sleeve 1, and the driving member 21 is connected to the locking assembly, and the driving member 21 is used to drive the locking assembly to lock with the structure 3.

[0025] The locking assembly includes: a first connector 22, a second connector 23 and a plurality of locking bodies 24. The first connector 22 and the second connector 23 are both annular, and the first connector 22 and the second connector 23 are arranged in parallel, and there is a preset distance between the first connector 22 and the second connector 23, and the preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0026] The first connector 22 is connected to the second end of the sleeve 1. Specifically, the inner diameter of the first connector 22 matches the inner diameter of the second end of the sleeve 1, so that the interior of the first connector 22 is connected to the interior of the sleeve 1. Preferably, the first connector 22 and the second end of the sleeve 1 are welded.

[0027] Each locking body 24 is disposed between the first connecting body 22 and the second connecting body 23 at intervals. Specifically, the first connecting body 22 and the second connecting body 23 are arranged up and down, and the first end ( Figure 1 The upper end shown in the figure) is connected to the outer wall of the first connecting body 22, and the second end ( Figure 1 The lower ends shown in the figure are connected to the outer wall of the second connecting body 23, and the locking bodies 24 are arranged at intervals between the first connecting body 22 and the second connecting body 23. Preferably, the locking bodies 24 are evenly distributed along the circumferential direction of the first connecting body 22.

[0028] Preferably, the first connecting body 22, the second connecting body 23 and the plurality of locking bodies 24 are integrally formed.

[0029] The driving member 21 is sequentially inserted into the sleeve 1, the first connecting body 22, the interior between each locking body 24 and the second connecting body 23, and the driving member 21 is connected to the second connecting body 23. The driving member 21 is used to drive the second connecting body 23 to move, and the second connecting body 23 drives each locking body 24 to deform away from the driving member 21 to lock with the structure 3. Specifically, the first connecting body 22 and the second connecting body 23 are arranged up and down, and each locking body 24 is arranged between the first connecting body 22 and the second connecting body 23 at intervals, so that the interior of the first connecting body 22 corresponds to the interior of the first connecting body 22, and the internal space enclosed by each locking body 24 is also connected to the interior of the first connecting body 22 and the interior of the first connecting body 22, thereby forming a penetration channel. The driving member 21 is inserted into the sleeve 1 and the penetration channel and then connected to the second connecting body 23. When the driving member 21 drives the second connecting body 23 to operate, each locking body 24 is deformed away from the penetration channel (i.e., deformed outward), and each locking body 24 is in an expanded state after deformation. Since each locking body 24 is arranged at intervals along the circumferential direction of the first connecting body 22, each locking body 24 after deformation is in a petal shape, thereby locking with the structure 3.

[0030] Preferably, the inner wall of the second connecting body 23 is provided with threads. The driving member 21 is a bolt, and the bolt is screwed with the second connecting body 23. When the bolt is screwed, the second connecting body 23 is driven to move toward the first connecting body 22, and the distance between the second connecting body 23 and the first connecting body 22 is gradually shortened, driving each locking body 24 to bend away from the bolt, that is, each locking body 24 is bent outward (outward, that is, away from the penetration channel), and each locking body 24 is in an expanded state, and the expanded locking bodies 24 are locked with the structure 3. Specifically, the inner wall of the first connecting body 22 is smooth, so that the driving member 21 can rotate freely in the first connecting body 22, and the bolt is rotatably penetrated in the sleeve 1, the first connecting body 22, the interior between each locking body 24 and the second connecting body 23 in sequence, and the bolt is screwed with the second connecting body 23.

[0031] In order to facilitate the outward bending of each locking body 24, the middle part of each locking body 24 is bent, and the bending is to bend away from the bolt. Specifically, each locking body 24 is not vertically arranged, but has a certain degree of curvature, which is arranged in the middle part of the locking body 24 and is bent away from the bolt, that is, outward, so that each locking body 24 is easy to bend outward under the action of the second connecting body 23.

[0032] The strength of the middle portion of each locking body 24 is smaller than the strength of the two ends of the locking body 24 , so that the locking body 24 can be bent outwards to lock the locking body 24 with the structure 3 .

[0033] Preferably, a plurality of saw teeth are arranged on the outer wall of each locking body 24 on the side away from the bolt, and specifically, the saw teeth are arranged at intervals and evenly distributed on the outer wall of the locking body 24. In this way, the locking force between the structure 3 and the locking body 24 can be effectively improved, and a stable connection between the insulation nail and the structure 3 can be ensured.

[0034] It can be seen that in this embodiment, the locking mechanism 2 has a simple structure and is easy to implement.

[0035] See also Figures 1 to 3 In the above embodiments, a blocking body 4 is provided at the first end of the sleeve 1, and an opening is provided at the center of the blocking body 4, and the first end of the sleeve 1 is connected to the opening. Specifically, the blocking body 4 can be circular, and the opening on the blocking body 4 is connected to the inside of the sleeve 1, so that the longitudinal cross-sections of the blocking body 4 and the sleeve 1 are roughly T-shaped. Preferably, the blocking body 4 and the sleeve 1 are integrally formed. The blocking body 4 contacts the outer wall of the structure 3, and the sleeve 1 is inserted into the drilled hole of the structure 3.

[0036] A spring washer is sleeved on the bolt, and the spring washer is placed between the head of the bolt and the blocking body 4. Specifically, the head of the bolt is placed outside the drilled hole of the structure 3, and the head of the bolt is arranged opposite to the blocking body 4, and the spring washer is sandwiched between the head of the bolt and the blocking body 4.

[0037] In specific implementation, the structure 3 may be a concrete structure, or a sintered porous brick, a color steel plate, an iron plate, etc., and this embodiment does not impose any limitation on this.

[0038] When the structure 3 is a sintered porous brick, a hole is drilled in the sintered porous brick, and each locking body 24 is bent and expanded outward, so that each locking body 24 is locked with the sintered porous brick, which improves the fastening effect of the locking body 24, and further improves the anchoring force of the insulation nail. In specific implementation, each locking body 24 can be completely bent or partially bent according to actual conditions. Even if it is partially bent, it can be locked with the sintered porous brick to achieve locking and fastening between the insulation nail and the sintered porous brick. The bending degree of each locking body 24 depends on the twisting of the bolt, and this embodiment does not impose any restrictions on this. In specific implementation, the insulation nail is applied to the wall base of old residential areas, and the wall base of old residential areas is mostly sintered porous bricks.

[0039] When the structure 3 is a heat-insulating extruded board 31 and a color steel board 32 connected together, see Figure 3 The sleeve 1 is inserted into the insulation extruded board 31 and the color steel plate 32, the blocking body 4 is placed outside the insulation extruded board 31, and each locking body 24 is placed outside the color steel plate 32. Each locking body 24 is bent and expanded outward, so that each locking body 24 is locked with the color steel plate 32. Even if the color steel plate 32 is thin, the insulation nail and the color steel plate 32 can be stably locked, thereby improving the fixing effect of the insulation nail. In specific implementation, the insulation nail is used in old residential areas with external elevators installed. The external elevator is sealed with the color steel plate 32. After the color steel plate 32 is sealed, each locking body 4 in the insulation nail is bent and expanded outward to form a petal shape, which just abuts against the color steel plate 32, thereby achieving the locking of the insulation nail and the color steel plate 32.

[0040] In summary, in this embodiment, the sleeve 1 is passed through the drilled hole of the structure 3, and the locking mechanism 2 is arranged at the second end of the sleeve 1 and locked with the structure 3, so that the insulation nail and the structure 3 are relatively fixed, and the locking mechanism 2 is connected to the sleeve 1 as a whole, which is convenient for installing the insulation nail and can also prevent the insulation nail from expanding prematurely. Moreover, the insulation nail can make each locking body 24 bend and expand outward when the bolt is tightened, so that each locking body 24 is locked with the structure 3, thereby improving the pull-out resistance and overall stability of the insulation nail. The operation of the insulation nail is simple and convenient, and it is easy to implement.
