Description

Technical Field

[0001] The invention belongs to the technical field of automatic doors, and in particular relates to an automatic door that can be opened in an emergency in case of fire. Background Art

[0002] Theoretically, automatic doors should be understood as an extension of the concept of doors. They are the development and improvement of the door's functions based on human needs. Automatic doors refer to a control unit that can recognize the action of a person approaching the door as a door opening signal, open the door through a drive system, and automatically close the door after the person leaves, and a system that controls the opening and closing process.

[0003] When most of the existing automatic doors are in use, they mainly use a sensing module to sense whether there are people in a designated area. When there are people, the drive system uses electricity to open the automatic door. In the event of a fire, there will be a power outage. When a power outage occurs, in a fire situation, because the sensing module and the drive system are both electrically driven to open, the automatic door cannot be opened quickly, causing people to take a detour, which affects the escape efficiency of people in an emergency and increases the escape time and distance. At the same time, in an emergency, if there is no power outage, the sensing module controls the drive system to open the automatic door. There is a certain time between opening and closing. In an emergency, people still need to wait for the automatic door to open a certain distance before they can escape, further wasting more time and having a poor use effect. Summary of the Invention

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention 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 the present invention and are not intended to limit the present invention.

[0026] See also Figure 1-5 The present invention provides a technical solution: an automatic door that can be opened in an emergency in case of fire, comprising a mounting frame 1 and an adjustment mechanism; a fixed box 2 is rotatably provided vertically at both ends of the inner cavity of the mounting frame 1, a mounting plate 4 is vertically provided on the inner side of the fixed box 2 and can slide horizontally, the front and rear ends of the mounting plate 4 are both laterally fixedly connected with door panels 9, the inner sides of the two door panels 9 are respectively slidably connected to the front and rear sides of the fixed box 2, and the outer sides of the multiple door panels 9 are all provided with sensing mechanisms.

[0027] The mounting frame 1 is mounted on a designated wall, with the front and rear sides of the mounting frame 1 both open, and the fixed box 2 is rotatably arranged vertically at both ends of the inner cavity of the mounting frame 1. The outer side surface of the fixed box 2 is laterally provided with a sliding groove that is adapted to the inner side surface of the mounting plate 4 to ensure the sliding stability of the mounting plate 4. The bottom of the mounting plate 4 can be provided with a universal wheel (not shown in the figure) according to specific usage requirements. The door panel 9 is driven to move by the mounting plate 4, thereby ensuring that the two door panels 9 are close to or away from each other according to specific usage requirements, thereby meeting the needs of closing or canceling the closure of the space. When the automatic door needs to be opened urgently in a fire, the door panel 9 is pushed to rotate the fixed box 2, so that the two mounting plates 4 are opened and rotated with the two fixed boxes 2 as the center.

[0028] The adjustment mechanism includes a sliding plate 3 and a plurality of rotating rods 12. The sliding plate 3 is vertically arranged in the inner cavity of the fixed box 2 so as to slide in the horizontal direction. The inner side surface of the sliding plate 3 is laterally fixedly connected to a fixed plate 5 with one end extending to the outside of the fixed box 2. One end of the fixed plate 5 is detachably connected to the surface of the mounting plate 4. A driving mechanism for driving the fixed plate 5 to move is provided on the inner side of the inner cavity of the fixed box 2. A plurality of rotating rods 12 are respectively vertically fixedly connected to the top and bottom of the fixed box 2, and the outer ends of the plurality of rotating rods 12 are respectively rotatably connected to the inner wall surface of the mounting frame 1.

[0029] The sliding plate 3 is slidably connected to the inner cavity of the fixed box 2, and the other end of the fixed plate 5 can be fixedly connected to the inner side surface of the sliding plate 3 by welding or bolts to ensure the stability of the fixed plate 5. One end of the fixed plate 5 is detachably connected to the mounting plate 4, thereby ensuring that when the driving mechanism moves the mounting plate 4 in the horizontal direction, the mounting plate 4 is driven to move in the horizontal direction to the specified position to ensure subsequent usage requirements. At the same time, the outer end of the rotating rod 12 is rotatably connected to the inner wall surface of the mounting frame 1 through a damping bearing, thereby ensuring the stability of the rotation of the rotating rod 12 to drive the fixed box 2 to rotate, and ensuring the positioning and fixing effect of the fixed box 2.

[0030] Furthermore, a plurality of teeth 6 are fixedly connected to the surface of the fixed plate 5 at even intervals in the horizontal direction. The driving mechanism includes a rotating shaft 7 and a gear 8. The rotating shaft 7 is rotatably arranged vertically on the inner side of the inner cavity of the fixed box 2. The gear 8 is laterally fixedly connected to the surface of the rotating shaft 7. The gear 8 meshes with the teeth 6 on the surface of the fixed plate 5.

[0031] A plurality of teeth 6 are fixedly connected to the surface of the fixed plate 5 by welding to ensure the stability of the fixed plate 5. At the same time, the rotating shaft 7 can rotate clockwise or counterclockwise, thereby ensuring that the rotation of the rotating shaft 7 drives the gear 8 to rotate. The gear 8 is engaged with the teeth 6 on the surface of the fixed plate 5, thereby driving the fixed plate 5 to move horizontally to a suitable position.

[0032] Furthermore, two driving mechanisms are provided, and the two driving mechanisms are respectively arranged on the inner side of the inner wall of the fixed box 2. The driving mechanism includes two horizontal plates 10 and a rotating shaft 7. The two horizontal plates 10 are respectively fixedly connected to the top and bottom of the inner side of the inner wall of the fixed box 2. The rotating shaft 7 is rotatably arranged vertically between the two horizontal plates 10. The bottom end of the rotating shaft 7 is rotatably connected to the top of the bottom horizontal plate 10. The bottom of the top horizontal plate 10 is vertically provided with a motor 11 that drives the rotating shaft 7 to rotate.

[0033] The horizontal plate 10 is fixedly connected to the inner wall surface of the fixed box 2 by welding. The fixing method is not specifically limited. The horizontal plate 10 is located on the side of the fixed box 2 facing the mounting plate 4, thereby ensuring that the fixed plate 5 has sufficient space for movement. The bottom end of the rotating shaft 7 is rotatably connected to the top of the corresponding horizontal plate 10 through a bearing to ensure the stability of the rotation of the rotating shaft 7. At the same time, the motor 11 drives the rotating shaft 7 to rotate clockwise or counterclockwise, so that the fixed plate 5 moves away from the fixed box 2 or moves into the inner cavity of the fixed box 2, thereby adjusting the position of the mounting plate 4 and the door panel 9.

[0034] Furthermore, both ends of the top and bottom of the inner wall of the installation frame 1 are recessed inward to form connecting grooves, and the outer ends of the plurality of rotating rods 12 are rotatably connected to the inner walls of the corresponding connecting grooves.

[0035] The connection groove ensures that the surface of the fixed box 2 contacts the inner wall of the installation frame 1. At the same time, the outer end of the rotating rod 12 is rotationally connected to the inner wall of the connection groove through a damping bearing, thereby ensuring the stability of the rotation of the rotating rod 12.

[0036] Furthermore, both ends of the top and bottom of the inner wall of the installation frame 1 are recessed inward to form a receiving groove, and the inner cavity of the receiving groove is provided with a roller 13, and the surface of the roller 13 contacts the surface of the fixing box 2.

[0037] The roller 13 is an existing structure and will not be explained in detail. The surface of the roller 13 contacts the surface of the fixed box 2, thereby ensuring the stability of the fixed box 2 during rotation and assisting the rotation of the fixed box 2 to reduce friction.

[0038] Furthermore, a vertical plate 20 is vertically fixedly connected to one side of the mounting plate 4 facing the fixing plate 5 , and a surface of the vertical plate 20 is detachably connected to an inner end of the fixing plate 5 .

[0039] The vertical plate 20 is fixedly connected to one side of the mounting plate 4 by welding or bolts, and the surface of the mounting plate 4 is detachably provided with connecting bolts running through it horizontally. The vertical plate 20 is connected to the fixed plate 5 by the connecting bolts, thereby fixing the position of the fixed plate 5. When the fixed plate 5 is disengaged from the vertical plate 20, the door panel 9 can be driven to move and disengage from the fixed box 2 by pulling the mounting plate 4, which is convenient for subsequent replacement and maintenance.

[0040] Furthermore, the front and rear sides of both ends of the bottom of the inner wall of the installation frame 1 are detachably provided with limit plates 17 laterally, and the bottom of the limit plate 17 is laterally fixedly connected with an inserting plate 18, and the surface of the limit plate 17 contacts the corresponding fixed box 2.

[0041] The front and rear sides of the fixed box 2 can be blocked by multiple limit plates 17 to prevent the fixed box 2 from rotating, thereby ensuring the normal use of the fixed box 2. At the same time, when the fixed box 2 needs to be rotated, the limit plates 17 are removed to cancel the blockage of the fixed box 2, thereby ensuring the rotation effect of the fixed box 2.

[0042] Furthermore, the front and rear sides of both ends of the bottom inner wall of the installation frame 1 are both recessed inwardly to provide a card-embedding groove that is compatible with the insert plate 18, and the front and rear sides of both ends of the bottom of the installation frame 1 are both threadedly connected with positioning bolts 19, which penetrate the insert plate 18 and are threadedly connected to the inner wall of the card-embedding groove.

[0043] The insert plate 18 is inserted into the card slot, and the positioning bolt 19 passes through the insert plate 18 so that it is threadedly connected to the inner wall surface of the card slot, thereby fixing the position of the insert plate 18. When the limit plate 17 needs to be removed, the positioning bolt 19 is removed to make it disengage from the mounting frame 1. After canceling the positioning of the limit plate 17, the limit plate 17 is removed, thereby canceling the limit on the fixed box 2.

[0044] Furthermore, multiple sensing mechanisms are provided, and the multiple sensing mechanisms are detachably arranged laterally on the outer sides of multiple door panels 9. The sensing mechanisms include a protective frame 14 detachably arranged laterally on the outer sides of the door panels 9, and a laser sensor 15 is provided in the inner cavity of the protective frame 14.

[0045] The protective frame 14 is an existing mechanism, which performs sensing when powered on. When it senses that a user is in front of the door panel 9, the driving mechanism moves the two mounting plates 4 away from each other, thereby ensuring usage requirements. The protective frame 14 can be connected to the front side of the door panel 9 by bolts to ensure the installation effect of the protective frame 14. When the laser sensor 15 detects that there is no user in the designated area in front, the two mounting plates 4 are moved close to each other for blocking.

[0046] Furthermore, the bottom of the outer side surfaces of the plurality of door panels 9 are all laterally fixedly connected with an anti-scalding layer 16 .

[0047] In this embodiment, the surface of the anti-scalding layer 16 is provided with an anti-scalding material, and the surface of the anti-scalding layer 16 may be provided with a handle to facilitate pushing the mounting plate 4 to rotate it with the fixed box 2 as the center.

[0048] When the two mounting plates 4 need to be pushed apart in an emergency, the plurality of positioning bolts 19 are removed to disengage the two mounting plates 4 from the plugging plate 18, and the limit plate 17 is moved upward. After the plugging plate 18 is disengaged from the locking groove, the limit plate 17 is removed, and the fixing box 2 is rotated to a suitable position under the rotation of the rotating rod 12 by pushing the two mounting plates 4, so that the two mounting plates 4 are moved away from each other and opened to a suitable position, thereby quickly pushing the mounting plates 4 apart in an emergency, avoiding time waste. When used in a normal state, when the two mounting plates 4 need to contact each other, the laser sensor 15 detects the user, and the motor 11 drives the rotating shaft 7 to rotate clockwise, thereby causing the fixing plate 5 to move in the direction away from the fixing box 2. The movement of the two fixing plates 5 drives the two mounting plates 4 to approach each other until they contact each other, thereby completing the blocking. When the fixing plate 5 moves, the sliding plate 3 ensures the stability of the movement of the fixing plate 5.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
