Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This utility model provides a hook installation structure for a civil defense door, the structure of which is as follows: Figure 2 - Figure 4 As shown, the device includes a fixing component 100 and a hook assembly 200. The fixing component 100 is embedded in the top plate 1 and has a cavity 110. The bottom of the fixing component 100 has a slot 120 with a strip structure communicating with the cavity 110. The bottom of the cavity 110 has a positioning groove 130 with a strip structure, and the positioning groove 130 intersects with the slot 120. The hook assembly 200 includes a mounting rod 210 and a hook body 220. The mounting rod 210 is horizontally arranged, and the upper end of the hook body 220 is fixedly connected to the middle part of the mounting rod 210. The mounting rod 210 can pass through the slot 120 and extend into the cavity 110. The mounting rod 210 is used to be placed in the positioning groove 130.

[0026] During construction, the fixing component 100 is pre-embedded in the top plate 1. When installing the hook assembly 200, the mounting rod 210 is passed through the slot 120 and extended into the cavity 110. The mounting rod 210 is rotated so that it is parallel to the positioning slot 130. Then, the mounting rod 210 is placed in the positioning slot 130, which limits the mounting rod 210, thus completing the installation of the hook assembly 200. When removing the hook assembly 200, the mounting rod 210 is moved out of the positioning slot 130. The mounting rod 210 is rotated so that it is parallel to the slot 120, and then moved out of the slot 120, thus completing the disassembly of the hook assembly 200. This is a detachable hook installation structure for air defense doors, which is convenient to install and remove and has strong applicability.

[0027] As a preferred embodiment, please refer to Figure 3 and Figure 4 The positioning groove 130 is perpendicular to the groove 120. When the mounting rod 210 is inserted into the cavity 110, rotating the mounting rod 210 by 90° will ensure that the mounting rod 210 is parallel to the positioning groove 130.

[0028] As a preferred embodiment, please refer to Figure 3 and Figure 4 The fixing component 100 includes a fixing member 140 and two positioning members 150. The fixing member 140 is embedded in the top plate 1. The fixing member 140 has a cavity 110 and a slot 120 at its bottom. The two positioning members 150 are both disposed in the cavity 110 and are located on both sides of the slot 120. The two positioning members 150 have positioning grooves 130. The two ends of the mounting rod 210 are respectively placed in the two corresponding positioning grooves 130. By avoiding the opening of the positioning grooves 130 on the fixing member 140, the strength of the bottom of the fixing member 140 is not weakened.

[0029] As a preferred embodiment, please refer to Figure 3 and Figure 4 The positioning element 150 includes two positioning rods 151, which are parallel and spaced apart, and both are perpendicular to the slot 120. The positioning groove 130 is formed between the two positioning rods 151, so that a positioning groove 130 can be formed on both sides of the slot 120 respectively. The two positioning grooves 130 can be used to position the two ends of the mounting rod 210 respectively, preventing the mounting rod 210 from rotating due to external force and falling out of the slot 120.

[0030] As a preferred embodiment, please refer to Figure 3 and Figure 4 The cavity 110 has a cuboid structure, which allows the bottom of the cavity 110 to be a planar structure.

[0031] As a preferred embodiment, please refer to Figure 3 and Figure 4 The fastener 140 has a cuboid structure, which facilitates its processing.

[0032] In a preferred embodiment, the fastener 140 is made of metal and its surface is galvanized to prevent corrosion.

[0033] As a preferred embodiment, please refer to Figure 2 The fixing component 100 also includes at least two reinforcing members 160. Each reinforcing member 160 is pre-embedded in the top plate 1 and is respectively disposed on both sides of the slot 120. The lower ends of the two reinforcing members 160 are connected to the bottom of the fixing member 140, and the upper ends of the two reinforcing members 160 are fixed to the top plate 1, which can enhance the installation strength of the fixing member 140.

[0034] As a preferred embodiment, please refer to Figure 2 The reinforcing member 160 is a reinforcing rib, which has a horizontally arranged first segment 161, two vertically arranged second segments 162, and two horizontally arranged third segments 163. The first segment 161 is located below the fixing member 140 and abuts against the bottom surface of the fixing member 140. The two second segments 162 are respectively located on both sides of the fixing member 140, and the lower ends of the two second segments 162 are respectively fixed to the two ends of the first segment 161. The two third segments 163 are both located above the fixing member 140 and are respectively located on both sides of the fixing member 140. The adjacent ends of the two third segments 163 are respectively fixed to the upper ends of the corresponding second segments 162. The reinforcing ribs can support the fixing member 140 upwards and enhance the installation strength of the fixing member 140.

[0035] As a preferred embodiment, please refer to Figure 2 and Figure 5 The hook assembly 200 also includes a connecting rod 230, which is vertically arranged. The upper end of the connecting rod 230 is fixedly connected to the middle of the mounting rod 210, and the lower end of the connecting rod 230 is fixedly connected to the upper end of the hook body 220. The length of the connecting rod 230 can be set according to actual needs so that the hook body 220 meets the requirements.

[0036] As a preferred embodiment, please refer to Figure 5 The hook 220 has a circular ring structure.

[0037] To better understand this utility model, the following is combined with... Figure 1 - Figure 5 The working principle of the technical solution of this utility model will be described in detail below:

[0038] During construction, the fixing component 140 is pre-embedded in the top plate 1. When installing the hook assembly 200, the mounting rod 210 is passed through the slot 120 and extended into the cavity 110. The mounting rod 210 is rotated so that it is parallel to the positioning slot 130. Then, the mounting rod 210 is placed in the positioning slot 130, which limits the mounting rod 210, thus completing the installation of the hook assembly 200. When removing the hook assembly 200, the mounting rod 210 is moved out of the positioning slot 130. The mounting rod 210 is rotated so that it is parallel to the slot 120, and then moved out of the slot 120, thus completing the disassembly of the hook assembly 200. This is a detachable hook installation structure for air defense doors, which is convenient to install and remove and has strong applicability.

[0039] The air defense door hook installation structure provided by this utility model has the following beneficial effects:

[0040] (1) The various reinforcing ribs can support the fastener 140 upwards, thereby enhancing the installation strength of the fastener 140;

[0041] (2) A positioning groove 130 is formed on both sides of the groove 120, so that the two ends of the mounting rod 210 can be positioned by the two positioning grooves 130 respectively, preventing the mounting rod 210 from rotating due to external force and falling out of the groove 120;

[0042] (3) The installation structure of the air defense door hook is detachable, easy to install and disassemble, and highly applicable.
