Description

Technical Field

[0001] This utility model relates to the field of garage door technology, specifically a garage door equipped with an emergency escape device. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of car ownership, garages, as important facilities for parking and protecting vehicles, are receiving increasing attention for their safety and functionality. In the design of garage doors, in addition to meeting basic opening, closing and anti-theft functions, it is also necessary to consider providing safe and convenient escape routes for people in emergency situations. Therefore, a garage door equipped with an emergency escape device has emerged to meet this market demand.

[0003] During the use of a garage, various emergencies may occur, such as natural disasters like fire and earthquakes, as well as accidents caused by human factors. These emergencies may prevent the garage door from opening normally, thereby endangering the lives of people inside the garage. Most existing garage emergency escape doors open inwards in one direction, allowing only one-way evacuation. If there are many people, the crowd may push and shove, causing the emergency escape door to fail to open, potentially resulting in incalculable casualties. Therefore, we propose a garage door equipped with an emergency escape device. Summary of the Invention

[0004] The purpose of this utility model is to provide a garage door equipped with an emergency escape device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a garage door equipped with an emergency escape device, comprising a garage door, a crossbeam fixedly connected to the inner center of the garage door, a T-shaped groove formed in the inner center of the crossbeam, a sliding plate slidably connected inside the T-shaped groove, one end of a central column fixedly connected to the bottom center of the sliding plate, an emergency escape door rotatably connected to the outer side of the central column, one end of a limit rod rotatably connected to the top of one side of the emergency escape door via a coupling, columns provided on both the left and right sides of the bottom of the crossbeam, two columns fixedly connected to the inner left and right sides of the garage door respectively, the other end of the limit rod rotatably connected to the top center of the right column via a coupling, multiple blocking columns slidably connected to the inner center of the left column, a fixing plate fixedly connected to the left side of each of the multiple blocking columns, one end of a fixing column rotatably connected to the left center of the fixing plate, and a threaded column fixedly connected to the other end of the fixing column.

[0006] As a further embodiment of this utility model: protruding strips are fixedly connected to the outer perimeter of the fixed column, and a pulley is provided on the left outer side of each of the protruding strips. The pulley slides on the outside of the fixed column, and a second pulley is provided on the pulley via a belt.

[0007] As a further embodiment of this utility model: a connecting rod is fixedly connected to the inner center of the second pulley, one end of the connecting rod is rotatably connected to the inner wall of the garage door, and a bevel gear is fixedly connected to the outer side of the end of the connecting rod near the second pulley.

[0008] As a further embodiment of this utility model: a bevel gear two meshes with the outer side of the first bevel gear, a rotating column passes through the center of the second bevel gear, the front and rear ends of the rotating column pass through the front and rear sides of the garage door respectively, and rotating bars are fixedly connected to the middle sides of the front and rear ends of the rotating column.

[0009] As a further embodiment of this utility model: a threaded groove is provided on the left side of the interior of the garage door, the threaded groove is located on the left side of the threaded post, and the threaded groove and the threaded post are arranged correspondingly.

[0010] As a further embodiment of this utility model: the right ends of the plurality of the blocking posts are all slidably connected to the middle of the left side of the emergency escape door through the middle of the right side column.

[0011] As a further embodiment of this utility model: the inner sidewall of the pulley is provided with a plurality of grooves, and the plurality of grooves and the plurality of protrusions are arranged in a one-to-one correspondence.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model, through the cooperation of the sliding plate and the central column, enables the emergency escape door to change its opening direction according to the direction of force after it is released from the limit of the blocking column. This facilitates evacuation operations from both sides of the garage door through the emergency escape door, avoiding the situation where the emergency escape door cannot be opened due to crowding. At the same time, with the cooperation of the limit rod, the opening angle of the emergency escape door will not exceed 270°, preventing the emergency escape door from excessively rotating and misaligning.

[0014] 2. This utility model uses a rotating bar to drive the bevel gear two on the rotating column to rotate, so that the bevel gear one connected to it synchronously drives the pulley two to rotate. At this time, since the pulley one is connected to the pulley two through a belt, the pulley one rotates synchronously. During this process, because the pulley one engages with multiple protrusions, the pulley one drives multiple protrusions and fixed posts to rotate at the same time as it rotates. Since the fixed posts are respectively connected to the threaded posts and the fixed plate, when the fixed posts rotate, they synchronously drive the threaded posts to rotate in the threaded grooves, causing the threaded posts to move and drive the fixed plate connected to the fixed posts to move synchronously. This causes multiple blocking posts to disengage from the emergency escape door, thereby allowing the emergency escape door to be opened and used normally. This achieves the goal of manually opening the emergency escape door when the garage door cannot be used normally. Moreover, because the rotating bar is relatively high, it can prevent children from accidentally operating it.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 - Appendix Figure 6This utility model discloses a garage door equipped with an emergency escape device, comprising a garage door 1, a crossbeam 2 fixedly connected to the inner middle side of the garage door 1, a T-shaped groove 3 opened in the inner middle side of the crossbeam 2, a sliding plate 4 slidably connected inside the T-shaped groove 3, a central column 5 fixedly connected to the bottom middle of the sliding plate 4, an emergency escape door 6 rotatably connected to the outer side of the central column 5, a limit rod 7 rotatably connected to one side of the top of the emergency escape door 6 via a coupling, columns 8 are provided on both the left and right sides of the bottom of the crossbeam 2, two columns 8 are fixedly connected to the inner left and right sides of the garage door 1 respectively, the other end of the limit rod 7 is rotatably connected to the top middle side of the right column 8 via a coupling, a plurality of blocking columns 9 are slidably connected to the inner middle side of the left column 8, a fixing plate 10 is fixedly connected to the left side of each of the plurality of blocking columns 9, a fixing column 11 is rotatably connected to the middle left side of the fixing plate 10, and a threaded column 12 is fixedly connected to the other end of the fixing column 11.

[0026] Specifically, through the coordinated arrangement of the sliding plate 4 and the central column 5, the emergency escape door 6, after being released from the limit of the blocking column 9, can change its opening direction according to the direction of the force. This facilitates evacuation operations from both sides of the garage door 1 through the emergency escape door 6, avoiding situations where the emergency escape door 6 cannot be opened due to crowding. At the same time, through the cooperation of the limiting rod 7, the opening angle of the emergency escape door 6 will not exceed 270°, preventing the emergency escape door 6 from excessively rotating and becoming misaligned.

[0027] In embodiment 1, protruding strips 13 are fixedly connected to the outer perimeter of the fixed column 11. Each of the protruding strips 13 has a pulley 14 on its left outer side. The pulley 14 slides on the outside of the fixed column 11. The pulley 14 is connected to a pulley 2 15 via a belt. A connecting rod 16 is fixedly connected to the center of the pulley 2 15. One end of the connecting rod 16 is rotatably connected to the inner wall of the garage door 1. A bevel gear 17 is fixedly connected to the outer side of the end of the connecting rod 16 near the pulley 2 15. A bevel gear 2 18 meshes with the outer side of the bevel gear 17. A rotating column 19 passes through the center of the bevel gear 2 18. The front and rear ends of the rotating column 19 pass through the front and rear sides of the garage door 1, respectively. A rotating bar 20 is fixedly connected to the middle side of both the front and rear ends of the rotating column 19.

[0028] Specifically, the rotating bar 20 drives the bevel gear 18 on the rotating column 19 to rotate, which in turn drives the bevel gear 17 connected to it to rotate the pulley 15. At this time, since the pulley 14 is connected to the pulley 15 via a belt, the pulley 14 rotates synchronously. During this process, the pulley 14 engages with multiple protrusions 13, causing the pulley 14 to rotate while driving the multiple protrusions 13 and the fixed column 11 to rotate. Since the fixed column 11 is connected to the threaded column 12 and the fixed plate 10 respectively, when the fixed column 11 rotates, it synchronously drives the threaded column 12 to rotate in the threaded groove 21, causing the threaded column 12 to move and drive the fixed plate 10 connected to the fixed column 11 to move synchronously. This causes the multiple blocking columns 9 to disengage from the emergency escape door 6, thereby allowing the emergency escape door 6 to be opened and used normally.

[0029] In embodiment 2, a threaded groove 21 is provided on the left side of the interior of the garage door 1. The threaded groove 21 is located on the left side of the threaded post 12. The threaded groove 21 and the threaded post 12 are correspondingly arranged. The right ends of multiple blocking posts 9 are slidably connected to the middle of the left side of the emergency escape door 6 through the middle of the right side post 8. Multiple grooves are provided on the inner side wall of the pulley 14. The multiple grooves and multiple protrusions 13 are correspondingly arranged.

[0030] Specifically, through the coordinated arrangement of multiple grooves and multiple protrusions 13, the pulley 14 can drive the fixed column 11 without affecting the rotation of the threaded column 12, and without affecting the fixed column 11 to rotate and move with the threaded column 12, thereby enabling multiple blocking columns 9 to detach from the emergency escape door 6.

[0031] Working principle:

[0032] In use, rotating the rotating bar 20 drives the bevel gear 18 on the rotating column 19 to rotate, causing the bevel gear 17 connected to it to synchronously drive the pulley 15 to rotate. Since the pulley 14 is connected to the pulley 15 via a belt, the pulley 14 rotates synchronously. During this process, the pulley 14 engages with multiple protrusions 13, causing the pulley 14 to rotate while simultaneously driving the multiple protrusions 13 and the fixed column 11 to rotate. Because the fixed column 11 is connected to the threaded column 12 and the fixed plate 10 respectively, when the fixed column 11 rotates, it synchronously drives the threaded column 12 to rotate within the threaded groove 21, causing the threaded column 12 to move. This, in turn, causes the fixed plate 10 connected to the fixed column 11 to move synchronously, allowing the multiple blocking columns 9 to disengage from the emergency escape door 6, thereby enabling the emergency escape door to open. Escape door 6 can be opened and used normally, allowing manual opening of the emergency escape door 6 when garage door 1 is not functioning properly. Due to the height of the rotating bar 20, accidental operation by children is prevented. Once the emergency escape door 6 can be opened, the sliding plate 4 and the central column 5 work together to allow the emergency escape door 6 to change its opening direction according to the direction of force after it is released from the limit of the barrier post 9. This facilitates evacuation operations from both sides of garage door 1 through the emergency escape door 6, preventing situations where crowds prevent the emergency escape door 6 from opening. Simultaneously, the limiting rod 7 ensures that the opening angle of the emergency escape door 6 will not exceed 270°, preventing excessive rotation and misalignment. This completes the entire workflow.
