Description

Technical Field

[0001] This utility model belongs to the field of civil defense door technology, specifically a leaning device for civil defense doors. Background Technology

[0002] During the upward or downward movement of the sealing beam structure of the air-raid shelter door, it is difficult to securely fix the sealing beam structure to the door leaf. Therefore, it is necessary to use some fixing components to fix the two together. However, while fixing, it is also necessary to ensure the movable relationship between the sealing beam structure and the door leaf. However, the existing fixing components can only fix the door leaf and cannot simultaneously meet the requirement of fixing without interfering with the vertical movement of the sealing beam structure. Therefore, there is an urgent need to design a leaning device for air-raid shelter doors to solve the above problems. Summary of the Invention

[0003] The purpose of this utility model is to provide a leaning device for air defense doors, which solves the problem that the existing fixing components mentioned above can only be fixed to the door leaf, and cannot simultaneously meet the requirement of not interfering with the vertical movement of the sealing beam structure while being fixed.

[0004] To solve the above-mentioned technical problems, this utility model provides a leaning device for a civil defense door, wherein the leaning device consists of several units, which are spaced apart and arranged on the back of each door leaf.

[0005] Each of the aforementioned leaning devices includes a leaning seat and side sliding plates slidably disposed on both sides of the leaning seat. One end of the leaning seat is fixedly disposed on the back of the corresponding door leaf, and the other end is provided with a limiting seat. The limiting seat cooperates with the side sliding plates on both sides to limit the movement. The bottom of each of the two side sliding plates is connected to a sealing beam structure through a connecting assembly. The sealing beam structure is driven up and down by a lifting mechanism to drive the two side sliding plates of each of the leaning devices to slide up and down on the outside of the corresponding leaning seat, thereby causing the sealing beam structure to separate from or seal the lower frame of the door frame of the air-raid shelter.

[0006] Furthermore, each of the side sliding plates of the inclined device is provided with a first limiting inclined surface on the upper outer side, and the inner side of the limiting seat is provided with a second limiting inclined surface, and the first limiting inclined surface and the second limiting inclined surface cooperate to limit the movement.

[0007] Furthermore, the inclined seat is connected to the back of the door leaf by fastening bolts.

[0008] Furthermore, the limiting seat and the inclined seat are obliquely fitted together, and the two are locked together by a number of locking bolts.

[0009] Furthermore, each of the connecting components includes a connecting post and a connecting plate. There are several connecting posts, and the several connecting posts are fixedly arranged at intervals on the top of the sealing beam structure. Each connecting post is embedded in the bottom of the connecting plate, and the connecting plate is fixed to the bottom of the side sliding plates on both sides of several inclined devices of each door leaf.

[0010] Furthermore, there are two limiting seats, which are respectively fixedly disposed on both sides of the inclined seat.

[0011] Furthermore, the lifting mechanism can be either an integral lock head lifting mechanism or a split lock head lifting mechanism.

[0012] The beneficial effects of this utility model are: the inclined leaning device for the air defense door of this utility model can be fixed to the door leaf at the same time, and the sealing beam structure can slide between the inclined leaning device when it is subjected to the force of the lifting mechanism moving up and down, thus avoiding the problem that the sealing beam structure cannot move due to interference from existing fixing components when it moves up and down.

[0013] The inclined device can improve the stability of the sealing beam structure's up-and-down movement by relying on the sliding of the side sliding plates and the inclined seat on both sides of each inclined device. At the same time, the first limiting inclined surface on the upper outer side of the side sliding plate and the second limiting inclined surface on the inner side of the limiting seat cooperate to limit the maximum downward movement of the sealing beam structure, thereby stabilizing the connection between the door leaf and the sealing beam structure. It can also reduce the problem of instability caused by the excessive force of the lifting mechanism extending too far, and at the same time, it can provide an auxiliary rebound effect for the door leaf when it is impacted.

Detailed Implementation

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In one specific embodiment of this utility model, such as Figure 1-3 As shown, a specific inclined leaning device for a civil defense door is disclosed. The inclined leaning device 1 consists of several units, which are spaced apart and arranged on the back of each door leaf 2.

[0021] Each leaning device 1 includes a leaning seat 11 and side sliding plates 12 slidably disposed on both sides of the leaning seat 11. One end of the leaning seat 11 is fixedly disposed on the back of the corresponding door leaf 2, and the other end is provided with a limiting seat 13. The limiting seat 13 cooperates with the side sliding plates 12 on both sides to limit the movement. The bottom of each side sliding plate 12 is connected to a sealing beam structure 15 through a connecting component 14. The sealing beam structure 15 is driven up and down by a lifting mechanism to drive the two side sliding plates 12 of each leaning device 1 to slide up and down on the outside of the corresponding leaning seat 11, so as to drive the sealing beam structure 15 to separate or seal with the lower frame of the door frame of the air-raid shelter. The sealing beam structure 15 in this embodiment is a conventional technology, so it is not described in detail. Any sealing beam structure 15 that can seal with the lower frame of the door leaf 2 can be used.

[0022] Each side sliding plate 12 of the inclined device 1 has a first limiting inclined surface 121 on its upper outer side and a second limiting inclined surface 131 on its inner side. The first limiting inclined surface 121 and the second limiting inclined surface 131 cooperate to limit the movement. The second limiting inclined surface 131 and one side straight wall of the inclined seat 11 form a limiting groove. The left side of the limiting groove extends into one side straight arm of the inclined seat 11 to allow the side sliding plate 12 to move up and down. The upper two sides of the side sliding plate 12 cooperate with the two side walls of the limiting groove to effectively prevent the side sliding plate 12 from moving down to the maximum limit.

[0023] The setting of the leaning device 1 can improve the stability of the sealing beam structure 15 in the up and down movement by relying on the sliding of the side sliding plates 12 and the leaning seat 11 on both sides of each leaning device 1. At the same time, the first limiting inclined surface 121 on the upper outer side of the side sliding plate 12 and the second limiting inclined surface 131 on the inner side of the limiting seat 13 cooperate to limit the maximum downward movement of the sealing beam structure 15, so as to stabilize the connection between the door leaf 2 and the sealing beam structure 15. It can also reduce the problem of instability caused by the excessive force of the lifting mechanism. At the same time, it can also provide an auxiliary rebound effect for the door leaf 2 when it is impacted.

[0024] The backrest 11 is connected to the back of the door leaf 2 by fastening bolts, which can realize a rigid connection between the door leaf 2 and the backrest 11.

[0025] There are two limit seats 13, which are fixedly installed on both sides of the inclined seat 11. The two limit seats 13 are obliquely engaged with the inclined seat 11, and the two are locked together by several locking bolts.

[0026] Each connecting component 14 includes a connecting post 141 and a connecting plate 142. There are several connecting posts 141, and the several connecting posts 141 are fixedly arranged at intervals on the top of the sealing beam structure 15. Each connecting post 141 is embedded in the bottom of the connecting plate 142. The connecting plate 142 is fixed to the bottom of the side sliding plates 12 on both sides of several inclined devices 1 of each door leaf 2.

[0027] The lifting mechanism can be either an integral lock head lifting mechanism or a split lock head lifting mechanism.

[0028] The inclined support device 1 for the air defense door of this utility model can be fixed to the door leaf 2, and at the same time, it can also allow the sealing beam structure 15 to slide between the inclined support device 1 when it is subjected to the force of the lifting mechanism moving up and down, so as to avoid the problem that the sealing beam structure 15 cannot move due to interference from the existing fixing components when it moves up and down.

[0029] The working process of this utility model is as follows:

[0030] Several inclined backing devices 1 are evenly distributed and spaced on the back of each door leaf 2 of the two door leaves 2. Side sliding plates 12 are slidably installed on both sides of each inclined backing device 11. Two limiting seats 13 are respectively installed on the ends of the inclined backing device 11 away from the door leaf 2 and locked with locking bolts. The lower part of the side sliding plate 12 extends downward through the limiting groove formed between the second limiting inclined surface 131 and the straight wall of one side of the inclined backing device 11, and its upper part is matched with the limiting groove for limiting. A connecting plate 142 is fixed on the extended side sliding plate 12, and several connecting columns 141 are fixed on the top of the sealing beam structure 15. Each connecting column 141 is correspondingly embedded in the hole at the bottom of the connecting plate 142, and the connecting plate 142 is locked to the top plate of the sealing beam structure 15 with fastening bolts.

[0031] When the sealing beam structure 15 is driven downward to seal under the lifting mechanism, the side sliding plates 12 on both sides of the inclined seat 11 of each inclined device 1 move downward in the limiting groove. When the first limiting inclined surface 121 of the side sliding plate 12 abuts against the inclined surface 131 of the limiting seat 13, the side sliding plate 12 stops descending, and at the same time the sealing beam structure 15 is sealed with the lower frame of the door frame.

[0032] When the sealing beam structure 15 is released from the seal by the lifting mechanism, the side sliding plates 12 on both sides of the inclined seat 11 of each inclined device 1 move upward in the limiting groove. The first limiting inclined surface 121 of the side sliding plate 12 and the second limiting inclined surface 131 of the limiting seat 13 move away from each other. When the connecting plate 142 abuts against the bottom of the two limiting seats 13, the lifting mechanism stops rising, and the sealing beam structure 15 and the side sliding plate 12 also stop moving.

[0033] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
