Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a fixing device for an opened civil air defense door. Background Art

[0002] Civil air defense doors are a type of civil defense protection equipment widely used at the entrances and exits of various civil air defense projects. Their features include a simple structure, reliable operation, and easy maintenance, making them suitable for projects with infrequent personnel and vehicle traffic. For projects requiring frequent access, such as underground shopping malls used for both peacetime and wartime operations, movable threshold doors or drop-down doors are more suitable, allowing for rapid transitions between peacetime and wartime functions. Furthermore, civil air defense doors offer excellent disaster prevention capabilities, such as fire, smoke, and water resistance, as well as protection against shock waves, biological warfare agents, and chemical warfare agents, fully meeting the requirements of civil air defense projects for both peacetime and wartime operations. However, due to their inherent thickness and the fact that civil air defense spaces are normally used as basements, traditional civil air defense doors are prone to movement when opened if accidentally touched by the owner, disrupting the normal use of the garage and potentially damaging vehicles traveling within the space, resulting in property losses for the owner. Therefore, improvements are needed. Utility Model Content

[0029] The following combination Figure 1-Figure 5 The invention describes a fixing device for a civil air defense door after it is opened.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, a fixing device for a civil air defense door after it is opened includes an expansion bolt 100 , a fixing ring 200 and a connecting piece 300 .

[0031] The expansion bolt 100 is fixed to the concrete wall against which the civil air defense door abuts after it is opened.

[0032] The fixing ring 200 is fixed to the free end of the expansion bolt 100 .

[0033] The connecting piece 300 is used to fix the handle of the civil air defense door to the fixing ring 200 after it is opened.

[0034] When in use, the fixing device for the civil air defense door after it is opened fixes the expansion bolt 100 on the concrete wall that the civil air defense door abuts after it is opened, and then uses the connecting piece 300 to fix the civil air defense door handle to the fixing ring 200 when the civil air defense door is opened. This can effectively prevent the civil air defense door from moving if the owner accidentally touches it, thereby improving the stability of the civil air defense door after it is opened. At the same time, the device is simple to operate and easy to use, and can prevent vehicles traveling in the civil air defense space from being damaged, thereby reducing the loss of the owner's property.

[0035] In this embodiment, the connecting member 300 includes a nylon rope 310, one end of the nylon rope 310 is fixedly connected to the civil defense door handle, and the free end of the nylon rope 310 is fixedly connected to the lock buckle 320. When the civil defense door is opened, the free end of the nylon rope 310 passes through the fixing ring 200, and the lock buckle 320 is fixed to the civil defense door handle.

[0036] In this embodiment, see Figure 3 The lock buckle 320 includes a locking ring 322, the bottom of the locking ring 322 is rotatably connected to a universal ring 321, the universal ring 321 is fixedly connected to the free end of the nylon rope 310, a locking groove 323 is provided on the locking ring 322, one end of the opening of the locking ring 322 is fixedly connected to a clamping block 327, and the other end of the opening of the locking ring 322 is rotatably connected to a locking rod 324, a torsion spring 325 is fixedly connected between the locking rod 324 and the locking ring 322, and the free end of the locking rod 324 is provided with a clamping groove 326 that is interference fit with the clamping block 327.

[0037] When the civil defense door is opened, the free end of the nylon rope 310 is passed through the fixed ring 200, and then the locking rod 324 is pressed toward the locking ring 322 to engage the civil defense door handle in the locking ring 322. The locking rod 324 is released, and under the action of the torsion spring 325, the locking rod 324 automatically returns to its original position. At this time, the blocking block 327 is just engaged in the slot 326.

[0038] like Figure 4 As shown, in one embodiment, the connecting member 300 includes a special-shaped ring 330, a groove 210 is opened on the fixing ring 200, the special-shaped ring 330 is located in the groove 210, the special-shaped ring 330 is connected end to end with the fixing ring 200, the special-shaped ring 330 includes an inner recess 331, and the two sides of the inner recess 331 are fixedly connected with an extrusion portion 332, and the extrusion portion 332 is connected to the fixing ring 200.

[0039] In this embodiment, the fixing ring 200 and the inner recess 331 are both tangent to the extrusion portion 332 . When the civil air defense door is opened, the civil air defense door handle is clamped in the inner recess 331 .

[0040] In this embodiment, the pressing portion 332 is elastic.

[0041] When the civil defense door is opened, the civil defense door handle is pressed into the inner recess 331 and the position of the civil defense door handle is fixed by squeezing the squeezing portion 332, thereby effectively preventing the civil defense door from moving. The operation is simple and easy to use.

[0042] like Figure 5 As shown, in one embodiment, a spring 340 is symmetrically fixedly connected to the inner wall of the fixing ring 200 , and the free end of the spring 340 is fixedly connected to a limiting rod 350 , which passes through the extrusion portion 332 , and the limiting rod 350 is slidably connected to the extrusion portion 332 .

[0043] In this embodiment, the free end of the limiting rod 350 is fixedly connected to a hemispherical body 360 , and the diameter of the hemispherical body 360 is the same as the outer diameter of the free end of the limiting rod 350 .

[0044] When the civil defense door is opened, the civil defense door handle is clamped in the inner recess 331. During this process, the limit rod 350 first moves toward the extrusion portion 332 under the extrusion of the civil defense door handle. When the civil defense door handle is just clamped in the inner recess 331, under the action of the spring 340, the limit rod 350 moves toward the direction of the civil defense door handle and abuts against the civil defense door handle, thereby limiting the movement of the civil defense door handle, and preventing the civil defense door from moving due to accidental touch by the owner.

[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and improvements are possible within the scope of the present invention, as would be apparent to one skilled in the art. These variations and improvements fall within the scope of the present invention. Therefore, the scope of the present invention shall be determined by the appended claims.
