Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of telescopic linear gates, and in particular to a sliding telescopic linear gate with good wind resistance. Background Technology
[0002] Sliding telescopic gates are automated access control devices widely used in outdoor entrances and exits of factories, residential communities, and commercial parks. Their core function is to open and close the entrance / exit through the telescopic movement of the gate. They offer advantages such as small footprint, high opening efficiency, and convenient operation, making them particularly suitable for scenarios requiring frequent switching of access states. With increasing outdoor usage demands, users are placing higher performance requirements on sliding telescopic gates, with "wind resistance" becoming a key indicator. Frequent gusts or strong winds in outdoor environments can easily impact the gate structure; therefore, wind resistance directly affects the gate's safety and stability.
[0003] The main structure of existing sliding telescopic linear gates is usually composed of multiple independent linear gate units spliced together. Adjacent linear gate units are connected and limited by "external snap-fit parts". Common snap-fit parts include metal buckles, L-shaped connecting plates or U-shaped slots. These snap-fit parts are generally fixed to the side wall or edge of the linear gate unit with bolts. By cooperating with the slots or bosses of the adjacent linear gate units, the lateral displacement of the linear gate units during the extension and retraction process is restricted, thereby realizing the overall extension and retraction of the gate.
[0004] However, the above-mentioned connection structure of traditional sliding telescopic linear gates has significant defects. Due to the gap between the locking parts and the linear gate units and the lack of an elastic limiting mechanism, when encountering gusts or strong winds, the adjacent linear gate units are prone to relative swaying, which leads to the loosening of the overall gate structure. In severe cases, there may be safety hazards such as the gate tilting or even the entire gate collapsing.
[0005] Therefore, we propose a sliding telescopic linear gate with better wind resistance to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sliding telescopic linear gate with better wind resistance.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A wind-resistant sliding telescopic linear gate includes a telescopic gate body, which comprises multiple linear gates arranged sequentially along a horizontal direction. A traction gate is fixedly installed at the front end of the front linear gates. The gate also includes: A gantry frame is set between two adjacent straight gates and is fixedly installed on the straight gate on the front side along the forward direction of the gate body. The specifications of the gantry frame are adapted to the specifications of multiple straight gates when they are telescopically stacked. The limiting plate is installed on the side wall of the gantry frame, which is located on the side of the linear gate in the forward direction. An elastic component is installed between the limiting plate and the side wall of the gantry frame. The end of the limiting plate away from the gantry frame abuts against the side wall of the rear linear gate. A ball bearing is installed at the end of the limiting plate that abuts against the rear linear gate.
[0008] Preferably, the sidewalls of the linear gate and the gantry are coated with a wear-resistant coating, which is a polytetrafluoroethylene coating.
[0009] Preferably, the gantry frame is designed as a frame surrounding a straight door, and the lower end of the gantry frame is equipped with casters.
[0010] Preferably, the limiting plate is made entirely of an elastic material.
[0011] Preferably, the elastic component includes a main shaft connected to the side wall of the gantry frame. The main shaft is arranged along the telescopic direction of the straight gate. A sleeve hole is opened on the side wall of the limiting plate. The other end of the main shaft extends into the sleeve hole of the limiting plate. A coil spring is connected between the main shaft and the inner wall of the sleeve hole.
[0012] Preferably, the limiting plate has a ball groove corresponding to the position of the ball, and the ball is rotatably disposed in the ball groove. The ball groove is a concave arc-shaped groove, and the inner diameter of the ball groove is adapted to the outer diameter of the ball. The part of the ball away from the limiting plate extends out of the ball groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by setting a gantry frame between adjacent linear gates, utilizes the combined action of the gantry frame and the limiting plate to limit the left and right directions of the adjacent linear gates. Combined with the elastic abutment action of the elastic component, it can eliminate the gaps of the traditional snap-fit structure in real time, preventing the gate from loosening when blown by the wind. At the same time, the continuous abutment of the limiting plate can balance the lateral force generated by the wind impact, effectively preventing the gate from tilting or falling over, and completely solving the core problem of poor wind resistance of traditional telescopic linear gates.
[0014] The spring structure of the elastic component enables an elastic connection between the limit plate and the linear gate, avoiding the hard contact wear of traditional snap-fit parts. The rolling friction design of the ball converts the sliding friction during the extension and retraction process into rolling friction, while reducing the direct wear between the limit plate and the linear gate and extending the service life.

[0021] Reference Figure 1-2A wind-resistant sliding telescopic linear gate includes a telescopic gate body 1, with an installation frame on the outer side of the telescopic gate body 1 for mounting the device at the location of use. The telescopic gate body 1 includes multiple linear gates 2 arranged sequentially in a horizontal direction. A traction gate 3 is fixedly installed at the front end of the front linear gate 2. The traction gate 3 is equipped with a drive power and moving wheels to drive the linear gate 2 to move and extend / retract. The gate also includes: The gantry frame 4, the straight gate 2, and the side walls of the gantry frame 4 are coated with a wear-resistant coating to further reduce the coefficient of friction with the limiting plate 5 and the ball bearing 7, and reduce the resistance to expansion and contraction. The wear-resistant coating is a polytetrafluoroethylene coating. The gantry frame 4 is set between two adjacent straight gates 2 and is fixedly installed on the straight gate 2 on the front side along the door's forward direction. The gantry frame 4 is fixed to the side wall of the straight gate 2 on the front side along the door's forward direction by bolts. When the door extends and retracts, the gantry frame 4 moves synchronously with the front straight gate 2. The specifications of the gantry frame 4 are adapted to the specifications when multiple straight gates 2 are extended and stacked. The gantry frame 4 is designed as a frame that surrounds the straight gate 2, and can wrap around adjacent straight gates 2 from the top and bottom sides to form multi-directional limiting. The lower end of the gantry frame 4 is equipped with moving wheels. Reference Figure 2-3 A limiting plate 5 is installed on the side wall of the gantry 4. The limiting plate 5 is made of elastic material, specifically polyurethane elastomer. It is rectangular in shape, combining elasticity and rigidity. It can absorb impact force through its own deformation during strong winds, avoiding structural damage caused by hard collisions between traditional metal limiting plates and the linear gate. It is positioned on one side of the linear gate 2 in the forward direction. An elastic component 6 is installed between the limiting plate 5 and the side wall of the gantry 4. The elastic component 6 includes a main shaft 601 connected to the side wall of the gantry 4. The main shaft 601 is positioned along the extension / retraction direction of the linear gate 2. A sleeve hole 602 is opened on the side wall of the limiting plate 5. The other end of the main shaft 601 extends into the sleeve hole 602 of the limiting plate 5. A coil spring 603 connects the main shaft 601 and the inner wall of the sleeve hole 602. When the limiting plate 5 is compressed, it retracts around the main shaft 601, and the coil spring 603... The spring 603 stores energy to ensure that the resisting force does not disappear and provides a limiting effect on the straight door 2. When encountering gusts of wind, the spring force of the coil spring 603 can buffer the instantaneous shaking of the straight door in real time and prevent the door structure from becoming loose. Reference Figure 4The end of the limiting plate 5 away from the gantry frame 4 abuts against the side wall of the rear straight door 2. A ball bearing 7 is provided at the end of the limiting plate 5 that abuts against the rear straight door 2, which converts the sliding friction between the limiting plate 5 and the straight door 2 into rolling friction, greatly reducing the resistance of the door's extension and retraction, and avoiding jamming caused by sliding contact. A ball groove 701 is provided on the limiting plate 5 corresponding to the position of the ball bearing 7. The ball bearing 7 is rotatably set in the ball groove 701. The ball groove 701 is a concave arc-shaped groove with rounded edges to prevent the ball bearing from being scratched by the groove when rolling. The inside of the ball groove 701 is filled with solid grease. The inner diameter of the ball groove 701 is adapted to the outer diameter of the ball bearing 7. The part of the ball bearing 7 away from the limiting plate 5 extends out of the ball groove 701.
