DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] Example 1
[0028] In this embodiment, if Figure 1-Figure 6 As shown, the anti-deformation lightweight civil air defense door includes a door frame 101 and a door panel 102. The door frame 101 and the door panel 102 are connected by hinges. A chamber 103 is arranged inside the door panel 102. The interior of the door panel 102 except the chamber 103 is filled with sound insulation and heat preservation and buffer materials, so that the civil air defense door has the effects of sound absorption protection and good sealing performance. The surfaces of the side walls of the door panel 102 are provided with movable grooves 104, and the movable grooves 104 are connected to the chamber 103 by guide grooves. Reinforcement layers 105 are installed on both sides of the door panel 102, and the reinforcement layers 105 make the door panel 102 have an impact resistance effect. In order to protect the safety of the passage, it also includes an installation mechanism 200 and a support mechanism 300. The installation mechanism 200 is arranged inside the chamber 103, and is used to fix the door panel 102 and the door frame 101. The support mechanism 300 is arranged on one side of the reinforcement layer 105 close to the outside, and is used to support the civil air defense door when it is opened. Before the anti-deformation lightweight civil air defense door is used, first check whether the door panel 102 can be used normally, and then turn the knob 207 to make the door bolt 201 and the slide groove 106 engage with each other, and then adjust the support mechanism 300 so that the civil air defense door enters a state to be used;
[0029] Among them Figure 2 , Figure 4 and Figure 5As shown, the installation mechanism 200 includes a bolt 201 that is slidably connected to the movable groove 104. During installation, the bolt 201 can be engaged with the corresponding slide groove 106, so that the door panel 102 and the door frame 101 can be engaged with each other. A connecting rod 202 is fixedly provided on the other side of the bolt 201, and one end of the connecting rod 202 is connected to a slider 203. One end of the slider 203 is arranged in an arc shape to facilitate sliding with the rotating member 204. The interior of the chamber 103 is rotatably connected to the rotating member 204. The slider 203 generates a force to move toward the outside of the slide groove 106 due to the rotation of the rotating member 204, so that the slider 203 can drive the connecting rod 202 to move, and then engage the bolt 201 into the inside of the slide groove 106, so as to fix the position of the door panel 102. The upper surface of the rotating member 204 A circular groove 205 is provided on the surface, and a plurality of racks are provided on the inner wall of the circular groove 205. A gear 206 is meshed and connected to the outer side of the rack. A twist 207 is fixedly provided on the top of the gear 206. One end of the twist 207 extends to the outer side of the reinforcing layer 105. The user rotates the twist 207 to rotate the gear 206, thereby driving the rack and the rotating member 204 to rotate, so that the slider 203 can slide relative to the rotating member 204, and then the slider 203 can be stuck in the arc groove 208, thereby improving the overall use effect. The twist 207 is clamped with the reinforcing layer 105 through a fixing frame, and the fixing frame is set as an L-shaped plate, so that after the door panel 102 and the door frame 101 are installed and fixed, the fixing frame can play a locking effect on the twist 207 and fix the twist 207;
[0030] Among them Figure 3 and Figure 4 As shown, the support mechanism 300 includes two symmetrically arranged fixing blocks 301. The fixing blocks 301 are arranged on the side of the civil air defense door close to the outside world. The civil air defense door has a certain weight even if it is a lightweight structure. When it is suspended in the air for a long time, gravity will drive the civil air defense door to generate a downward force, thereby squeezing the door panel 102. The door panel 102 may tilt, causing inconvenience in opening and closing. The support mechanism 300 can effectively prevent this situation from happening. Threaded holes are provided on the surfaces of the fixing blocks 301, and screws 302 are provided inside the threaded holes. Both ends of the screws 302 extend to the threaded holes. On the outside, a handle 303 is fixedly provided at one end of the screw rod 302, and a support block 304 is provided at the other end of the screw rod 302. The screw rod 302 is driven to rotate by rotating the handle 303, and the support block 304 is rotated downward, thereby generating an upward force on the door panel 102. By adjusting the handle 303 at different positions, the door panel 102 is kept in a horizontal state, preventing the door panel 102 from being drooped by gravity due to being suspended in the air for a long time when opened, thereby preventing the door panel 102 and the door frame 101 from being able to rotate normally, and preventing the deformation of the lightweight civil air defense door in an anti-deformation form;
[0031] Among them Figure 2 and Figure 5As shown, a slide groove 106 adapted to the door bolt 201 is provided on the inner wall of the door frame 101. The slide groove 106 is used to facilitate placement of the door bolt 201. The door bolt 201 is slidably connected to the slide groove 106.
[0032] Among them Figure 5 As shown, the connecting rod 202 is slidably connected to the guide groove, so that the connecting rod 202 can move along the direction of the guide groove, playing a guiding and limiting role. The slider 203 is connected to the inner wall of the guide groove through a spring, and the spring is sleeved on the outer side of the connecting rod 202. The spring enables the slider 203 to automatically return to its original position.
[0033] Among them Figure 5 and Figure 6 As shown, arc grooves 208 are symmetrically arranged on the outer side of the rotating member 204. The arc grooves 208 are used to facilitate the clamping of the slider 203. A limit block 209 is arranged on one side of the arc groove 208. The limit block 209 limits the rotation angle of the knob 207 to avoid excessive rotation angle, which causes the slider 203 to return to its original position and makes it impossible to achieve the splicing operation between the door panel 102 and the door frame 101.
[0034] Among them Figure 6 As shown, the arc groove 208 is adapted to the specifications and dimensions of the slider 203, and the number of the arc grooves 208 and the slider 203 is consistent, so that the slider 203 can be easily inserted into the arc groove 208, which is convenient for fixing the door bolt 201 and ensuring the stability of the docking between the door panel 102 and the door frame 101;
[0035] Example 2
[0036] The difference from Example 1 is that Figure 7 As shown, the reinforcing layer 105 includes a fireproof layer and a protective layer. The fireproof layer insulates and fireproofs the civil air defense door. Silica gel particles and SMC composite materials are laid on one side of the protective layer. Under the action of the silica gel particles, the civil air defense door has a buffering effect, which is convenient for protecting the door panel 102 and improving the service life. The SMC composite material can reduce the weight of the civil air defense door and is easy to use.
[0037] When in use, first close the door panel 102 and then turn the knob 207, so that the gear 206 drives the rack to engage and transmit, and then drives the rotating member 204 to rotate, so that the slider 203 can slide relative to the rotating member 204, and then the slider 203 is inserted into the arc groove 208, thereby driving the connecting rod 202 to move, and the door bolt 201 is pushed outward from the door frame 101, so that the slide groove 106 contacts the door bolt 201, and the engagement operation is realized, which is convenient for the installation and fixation between the door panel 102 and the door frame 101, improves the stability of the door panel 102, and has good practicality.
[0038] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
