Description

Technical Field

[0001] This utility model relates to the field of civil defense door installation technology, specifically to an auxiliary installation device for heavy-duty civil defense doors. Background Technology

[0002] Patent application publication number CN221741884U discloses an auxiliary support device for the installation of heavy-duty air-raid shelter doors, comprising: a base frame; a lifting plate, wherein fixed blocks are fixed at both sides of the top of one end of the base frame, and the two sides of one end of the lifting plate are rotatably mounted on the fixed blocks; a first driving mechanism is connected between the base frame and the lifting plate, and the lifting plate moves in a circular motion around the fixed blocks via the first driving mechanism; a support plate is fixed to the surface of the lifting plate; and a movable plate, wherein a second driving mechanism is provided between the movable plate and the base frame, and the movable plate moves linearly via the second driving mechanism; a counterweight is fixed to the top of the movable plate. This utility model uses the lifting plate to vertically support the air-raid shelter door, increasing the supporting force of the base frame during support and preventing one end of the base frame from tilting forward and failing to provide proper support.

[0003] When installing a civil defense door, the hinge structure used for installation often deviates from the pre-installed hinge structure on the wall of the door opening in terms of height and distance, making it difficult to position the connection structure together, thus making it difficult to install the civil defense door. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary installation device for heavy-duty civil defense doors.

[0005] The technical problem solved by this utility model is to accurately adjust the air defense door onto the connecting mechanism on the wall of the door opening, so as to facilitate the operator to install it.

[0006] This utility model can be achieved through the following technical solution: it includes several universal wheels installed at the bottom of the base, a slider slidably installed through the top of the base, a guide plate fixedly installed on the top of the slider, a support plate slidably installed through the guide plate, a mounting frame fixedly installed on the side of the support plate away from the guide plate, a sliding bracket slidably installed through the mounting frame, a clamping plate fixedly installed on the side of the sliding bracket near the support plate, a screw threadedly connected to the side of the sliding bracket away from the support plate, one end of the screw slid being rotatably connected to one side of the mounting frame, and a lifting component for moving the support plate vertically and a matching balancing component for maintaining the balance of the support plate during movement installed at the bottom of the mounting frame.

[0007] A further technical improvement of this utility model is that a brake pad is installed on the universal wheel.

[0008] Furthermore, the side of the clamping plate adjacent to the support plate is made of rubber material.

[0009] Furthermore, weight-adding blocks are fixedly installed on both sides of the top of the base.

[0010] Furthermore, the lifting assembly includes a sliding bracket 2 slidably connected to one side of the base, a screw 2 rotatably mounted through the sliding bracket 2, a knob fixedly mounted at one end of the screw 2, a slider 2 slidably connected to one side of the base and threadedly connected to the outer peripheral wall of the screw 2, a push-pull plate 1 rotatably mounted on the side of the slider 2 away from the base, and the end of the push-pull plate 1 away from the slider 2 rotatably connected to the bottom side of the support plate.

[0011] Furthermore, the supporting balancing components include a sliding bracket three that is slidably connected to one side of the base, a guide rod that is fixedly installed on the sliding bracket three, a slider three that is slidably connected to one side of the base that is slidably installed on the outer peripheral wall of the guide rod, a push-pull plate two that is rotatably installed on the side of the slider three away from the base, and the end of the push-pull plate two that is away from the slider three that is rotatably connected to the bottom side of the support plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This application involves vertically placing the air-raid shelter door between the support plate and the mounting frame, and clamping and fixing it with a clamping plate. Then, a slider moves the air-raid shelter door horizontally through the support plate, and a lifting component moves the support plate vertically to adjust the positional relationship between the air-raid shelter door and the door opening. This ensures that the connection structure of the air-raid shelter door is precisely positioned with the connection structure on the wall of the door opening, making it convenient for operators to install.

[0014] 2. This application uses a matching balancing component to maintain the balance of the support plate when it moves on the base, preventing the weight of the air defense door on the support plate from being too great and causing the base to tip over. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Please see Figure 1-4 As shown, this embodiment provides an auxiliary installation device for a heavy-duty air defense door, including a base 1. Several casters 2 are installed at the bottom of the base 1, and brake pads (not shown in the figure) are installed on the casters 2. Weight blocks 3 are fixedly installed on both sides of the top of the base 1. The weight blocks 3 are used to maintain the balance of the base 1 and prevent the base 1 from tipping over. A slider 4 is slidably installed through the top of the base 1. A guide plate 5 is fixedly installed on the top of the slider 4. A support plate 6 is slidably installed through the guide plate 5. An installation frame 7 is fixedly installed on the side of the support plate 6 away from the guide plate 5. A sliding bracket 8 is slidably installed through the installation frame 7. A clamping plate 9 is fixedly installed on the side of the sliding bracket 8 near the support plate 6. The side of the clamping plate 9 near the support plate 6 is made of rubber material. A screw 10 is threadedly connected through the side of the sliding bracket 8 away from the support plate 6. One end of the screw 10 is rotatably connected to one side of the installation frame 7. A lifting component 11 and a matching balancing component 12 are installed at the bottom of the installation frame 7.

[0025] When screw 10 is rotated clockwise, screw 10 will drive clamping plate 9 to move towards support plate 6 through sliding bracket 8, so as to reduce the distance between support plate 6 and clamping plate 9. Conversely, rotating screw 10 will increase the distance between support plate 6 and clamping plate 9.

[0026] The lifting assembly 11 includes a sliding bracket 111 slidably connected to one side of the base 1. A screw 112 is rotatably mounted through the sliding bracket 111. A knob 113 is fixedly mounted at one end of the screw 112. A slider 114 slidably connected to one side of the base 1 is threaded to the outer peripheral wall of the screw 112. A push-pull plate 115 is rotatably mounted on the side of the slider 114 away from the base 1. The end of the push-pull plate 115 away from the slider 114 is rotatably connected to one side of the bottom of the support plate 6.

[0027] When the screw 112 is turned clockwise by the knob 113, the screw 112 will drive the slider 114 to slide along one side of the base 1, thereby causing the slider 114 to push the support plate 6 to move vertically upward along the guide plate 5 through the push-pull plate 115. Conversely, it will cause the support plate 6 to move vertically downward along the guide plate 5.

[0028] The matching balance component 12 includes a sliding bracket 121 slidably connected to one side of the base 1, a guide rod 122 fixedly installed on the sliding bracket 121, a slider 123 slidably connected to one side of the base 1 on the outer peripheral wall of the guide rod 122, a push-pull plate 124 rotatably installed on the side of the slider 123 away from the base 1, and the end of the push-pull plate 124 away from the slider 123 rotatably connected to one side of the bottom of the support plate 6.

[0029] When the support plate 6 moves vertically, the support plate 6 will drive the slider 114 to slide along the guide rod 122 through the push-pull plate 124, so that the slider 123 and the slider 114 keep the motion state consistent, so as to maintain the balance of the support plate 6 on the base 1.

[0030] In use, the air-raid shelter door to be installed is first placed vertically between the mounting frame 7 and the support plate 6. Then, the screw 10 is rotated, causing the screw 10 to drive the clamping plate 9 to clamp the air-raid shelter door through the sliding bracket 8. After the air-raid shelter door is securely fixed between the support plate 6 and the mounting frame 7, the air-raid shelter door installed on the support plate 6 is moved to the doorway where it is to be installed through the base 1. Then, the screw 112 is rotated to adjust the vertical height of the air-raid shelter door through the lifting assembly 11, and the balance of the air-raid shelter door is maintained by the matching balancing assembly 12, so that one side of the air-raid shelter door needs to be flush with the wall. Align the hinged part with the pre-set hinge structure on the wall, and then push and pull the support plate 6 so that the support plate 6 slides on the top of the base 1 through the slider 4, thereby moving the air defense door towards the door frame of the doorway so that the hinge structure of the air defense door can be inserted into the hinge structure on the wall for installation. After the air defense door is hinged to the wall, turn the screw 10 counterclockwise so that the screw 10 drives the clamping plate 9 away from the air defense door through the sliding bracket. Then, the universal wheel 2 drives the base 1 to move away from the hinge of the air defense door, and the air defense door can be pulled out from between the support plate 6 and the mounting bracket 7.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
