Abstract
Description
Technical Field
[0001] This utility model relates to the field of sliding door technology, specifically a collision-resistant sliding door. Background Technology
[0002] To control traffic flow, sliding doors are typically installed at entrances and exits. However, in high-security locations like substations, the possibility of forced entry, particularly by vehicles, must be considered. Existing sliding doors rely entirely on the door's own structural strength to withstand impacts, resulting in low collision resistance. Utility Model Content
[0003] The purpose of this invention is to provide a collision-resistant sliding door to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] The anti-collision sliding gate includes a door leaf that can move horizontally along a wall, and a first door frame and a second door frame respectively installed on the walls on both sides of the door opening. The door leaf is slidably installed in the first door frame. When the door leaf moves horizontally to a preset position to close the door opening, the first end of the door leaf is inserted into the first door frame, and the second end of the door leaf is inserted into the second door frame. A first limiting component is provided between the first end of the door leaf and the first door frame, and a second limiting component is provided between the second end of the door leaf and the second door frame. When the door leaf is impacted while the door opening is closed, the first door frame forms at least a tensile constraint on the first end of the door leaf through the first limiting component, and the second door frame forms at least a tensile constraint on the second end of the door leaf through the second limiting component, thus preventing the door leaf from deforming.
[0006] Compared with the prior art, the beneficial effects of this utility model are:
[0007] When the door leaf of this invention is impacted while the doorway is closed, the two ends of the door leaf transmit the force to the first door frame and the second door frame respectively, forming a constraint on the two ends of the door leaf, preventing the deformation of the door leaf, and improving the anti-collision performance of the sliding door.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-6 In this embodiment of the present invention, the anti-collision sliding door includes a door leaf 1 that can move horizontally along the wall, and a first door frame 21 and a second door frame 22 respectively set on the walls on both sides of the door opening. The door leaf 1 is slidably installed in the first door frame 21. When the door leaf 1 moves horizontally to a preset position to close the door opening, the first end of the door leaf 1 is inserted into the first door frame 21, and the second end of the door leaf 1 is inserted into the second door frame 22. A first limiting component 31 is provided between the first end of the door leaf 1 and the first door frame 21, and a second limiting component 32 is provided between the second end of the door leaf 1 and the second door frame 22. When the door leaf 1 is impacted while the door opening is closed, the first door frame 21 forms at least a tensile constraint on the first end of the door leaf 1 through the first limiting component 31, and the second door frame 22 forms at least a tensile constraint on the second end of the door leaf 1 through the second limiting component 32, thereby preventing the door leaf 1 from deforming.
[0016] When the door leaf 1 of this utility model is impacted while the doorway is closed, the two ends of the door leaf 1 transmit the force to the first door frame 21 and the second door frame 22 respectively. By decomposing the force at both ends of the door leaf 1, multi-directional constraint is achieved, which hinders the deformation of the door leaf 1 and improves the anti-collision performance of the sliding door.
[0017] In specific implementation, the door leaf 1 in this application is installed at the door opening wall via a slide rail, and a traveling wheel is installed at the bottom of the door leaf 1. The door leaf 1 is moved and guided by the traveling wheel rolling on the slide rail. In addition, the door leaf 1 can be driven by a motor or manually. The technology of being driven by a motor is already a very mature technology in the existing sliding door technology, and will not be elaborated here.
[0018] The first limiting component 31 includes at least one limiting pin disposed at the first end of the first door frame 21 or the door leaf 1.
[0019] When the limiting pin is set on the first door frame 21, the limiting pin can be inserted into the first end of the door leaf 1 to fix the relative position of the first door frame 21 and the door leaf 1. When the limiting pin is not inserted into the door leaf 1, it does not affect the movement of the door leaf 1.
[0020] When the limiting pin is set on the first end of the door leaf 1, the first door frame 21 is located between the limiting pin and the second door frame 22, and the limiting pin is fixedly connected to the door leaf 1; when the door leaf 1 is impacted while the door opening is closed, the limiting pin abuts against the first door frame 21, forming a tensile constraint on the door leaf 1.
[0021] The door leaf 1 passes through the first door frame 21 from inside the first door frame 21. The limiting pin passes through the first end of the door leaf 1 and the two ends of the limiting pin protrude from the front and rear sides of the door leaf 1 respectively. When the door leaf 1 is impacted while the door opening is closed, both ends of the limiting pin abut against the first door frame 21, forming a tensile constraint on the door leaf 1. This makes the limiting pin more stable when it abuts against the first door frame 21.
[0022] It should be noted that the solution in this application where the limiting pin protrudes from the front and rear sides of the door leaf 1 can also be: the end of the limiting pin is welded and fixed with a mounting seat, and the mounting seat is fixed to the front and rear sides of the first end of the door leaf 1 by bolts, thereby fixing the limiting pin to the door leaf 1.
[0023] The second limiting component 32 includes at least one pin 321 disposed on the second door frame 22. The pin 321 can be inserted into the second end of the door leaf 1 to fix the relative position of the second door frame 22 and the door leaf 1. When the pin 321 is not inserted into the door leaf 1, it does not affect the movement of the door leaf 1.
[0024] The latch 321 is driven by a drive mechanism provided on the second door frame 22 to insert into or withdraw from the second end of the door leaf 1.
[0025] The driving mechanism includes a driving device 322 fixed to the second door frame 22 and a connecting rod 323 driven by the driving device 322. A pin 321 is connected to the connecting rod 323 and moves with the connecting rod 323. When the driving device 322 is running, the pin 321 is driven by the connecting rod 323 to insert or withdraw from the second end of the door leaf 1.
[0026] Specifically, the connecting rod 323 is fixed on the movable end of the drive device 322, and the connecting rod 323 is hinged to one end of the pin 321.
[0027] In a preferred embodiment of the present invention, when the latch 321 is inserted into the door leaf 1, it can pass through the second end of the door leaf 1, and the door leaf 1 passes through the second door frame 22 from inside the second door frame 22; when the door leaf 1 is impacted while the door opening is closed, both ends of the latch 321 abut against the second door frame 22, forming a tensile constraint on the second end of the door leaf 1.
[0028] The drive device 322 is one or more of a hydraulic telescopic rod, an electric telescopic rod, and a pneumatic telescopic rod.
[0029] The drive device 322 in this application can specifically be a pneumatic telescopic rod of model SC80X250.
[0030] Specifically, the latch 321 in this application can be set to three, one on the upper half of the door leaf 1 and two on the lower half of the door leaf. Each latch 321 is connected to the connecting rod 323. The connecting rod 323 is set vertically. A sleeve or guide seat can be fixed on the second door frame 22. The sleeve or guide seat is slidably connected to the latch 321 to improve the stability of the latch 321 operation.
[0031] It should be noted that when the first limiting component 31 in this application is selected as a limiting pin set on the first door frame 21, the way the first limiting component 31 is installed on the first door frame 21 is the same as the way the second limiting component 32 is installed on the second door frame 22.
[0032] When the door leaf 1 moves to the closed doorway position, sealing components (not shown in the figure) are respectively installed between the first door frame 21 and the second door frame 22 to seal both ends of the door leaf 1. The sealing components are sealing airbags, which are directly fixed to the side walls of the first door frame 21 and the second door frame 22 facing the water-facing side of the door leaf 1. After the door leaf 1 moves laterally to close the doorway, the sealing airbag is inflated by an external air source. The expansion of the sealing airbag seals the water-facing side of both ends of the door leaf 1 and the door frame 2. At this time, the door frame 2 is sealed with concrete or sealant to the wall at the doorway.
[0033] The bottom of the door leaf 1 is provided with a sealing strip (not shown in the figure). The first door frame 21 and the second door frame 22 on both sides of the door opening or the wall on both sides of the door opening are provided with a downward driving device 4. After the door leaf 1 closes the door opening, the power output end of the downward driving device 4 acts on the door leaf 1 to press down the door leaf 1, so that the bottom of the door leaf 1 forms a seal with the ground.
[0034] The downward driving device 4 is a jack that is fixedly installed on the top of the door frame 2 on both sides of the door opening. The movable end of the jack is set downward and can move vertically up and down. When the movable end of the jack moves downward, it can press on the top of the door leaf 1 and press the door leaf 1 down.
[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the contents not described in detail in this specification are all prior art known to those skilled in the art.
