A retractable gate buffer device

Abstract

This utility model discloses a telescopic gate buffer device, including a telescopic gate placement base plate, a side fixed wall at the top of the telescopic gate placement base plate, a telescopic gate drive frame at the top of the telescopic gate placement base plate, and a drive wheel at the bottom of the telescopic gate drive frame. A triangular blocking block is installed on one side of the side fixed wall via a wheel buffer energy reduction component, and the triangular blocking block is located on one side of the drive wheel. In this telescopic gate buffer device, the contact buffer component allows the telescopic gate drive frame to contact the side buffer plate during operation. After the side buffer plate moves, it compresses a spring, and the buffer effect of the spring prevents the telescopic gate drive frame from colliding with the side fixed wall. The wheel buffer energy reduction component is driven to move onto an arc-shaped groove, where it rotates and slips on a rotating roller, thereby reducing the force of the telescopic gate drive frame continuing to move forward.

Description

Technical Field

[0001] This utility model relates to the field of telescopic gate technology, and in particular to a telescopic gate buffer device. Background Technology

[0002] Telescopic gates are a common type of automatic door system, widely used at entrances and exits of factories, businesses, schools, government agencies, and other locations. They open and close by telescopic movement, offering advantages such as space saving, ease of operation, and high safety and reliability. A telescopic gate is controlled by a gate body and a drive mechanism. The gate body consists of multiple telescopic sections, typically made of aluminum alloy or stainless steel, with a painted or electrophoretic finish for good corrosion resistance and aesthetics. The telescopic sections are connected by pulleys and tracks, enabling flexible telescopic movement. The drive mechanism includes a motor and a gearbox. The motor provides power, and the gearbox converts the high-speed rotation of the motor into a low-speed, high-torque output, driving the telescopic gate's telescopic movement.

[0003] During operation, some telescopic gates have a maximum extension range that exceeds the width of the doorway. Since the extension range is manually controlled, the gate often collides hard with the wall if the stopping time is not properly controlled, causing damage to the gate and requiring frequent maintenance. Therefore, a telescopic gate buffer device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a retractable gate buffer device to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A retractable gate buffer device includes a retractable gate placement base plate, a side fixed wall at the top of the retractable gate placement base plate, a retractable gate drive frame at the top of the retractable gate placement base plate, a drive wheel at the bottom of the retractable gate drive frame, a triangular blocking block installed on one side of the side fixed wall via a wheel buffer energy reduction component, the triangular blocking block being located on one side of the drive wheel, a side buffer plate installed on one side of the side fixed wall via a contact buffer component, a trigger component installed inside the side fixed wall, and an alarm light installed at the top of the side fixed wall, the trigger component being connected to the alarm light.

[0007] Preferably, the contact buffer assembly includes two push slots formed on one side of the side fixed wall, and a first push rod and a second push rod are fixedly installed on one side of the side buffer plate. The first push rod and the second push rod extend into the two push slots respectively, and each is fixedly installed with a compression spring.

[0008] Preferably, a telescopic rubber sleeve is fixedly installed on one side of the side buffer plate, and the telescopic rubber sleeve is connected to the side of the side fixed wall.

[0009] Preferably, the triggering component includes an upper slot formed on the inner wall of the top side of the push groove, an arc-shaped top block is movably installed in the upper slot, the bottom of the arc-shaped top block is located in the push groove and is adapted to the first push rod, a first trigger block is fixedly installed on the inner wall of the top side of the upper slot, and a second trigger block is fixedly installed on the top of the arc-shaped top block, and the first trigger block and the second trigger block are electrically connected.

[0010] Preferably, a guide post is fixedly installed on the top of the arc-shaped top block, a guide groove is provided on the inner wall of the top side of the upper slot, the top of the guide post extends into the guide groove, and a reset spring is fixedly installed between the arc-shaped top block and the inner wall of the top side of the upper slot.

[0011] Preferably, the wheel buffer energy reduction assembly includes an extrusion groove formed on the side of the side fixed wall, an extrusion rod fixedly installed on the side of the triangular blocking block, one end of the extrusion rod extending into the extrusion groove, and an extrusion spring fixedly installed between the end of the extrusion rod and the inner wall of the extrusion groove.

[0012] Preferably, the side of the triangular blocking block is provided with an arc-shaped groove, and multiple rotating rollers are rotatably mounted on the arc-shaped groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the sliding gate buffer device is equipped with a contact buffer component. When the sliding gate is running, the sliding gate drive frame contacts the side buffer plate. After the side buffer plate moves, it squeezes the compression spring. The buffering effect of the compression spring is used to avoid the collision between the sliding gate drive frame and the side fixed wall.

[0014] The wheel buffer energy reduction component is set up so that the drive wheel will contact the triangular blocking block. The compression spring also provides a buffering and blocking effect. The drive wheel moves to the arc-shaped groove and the drive wheel rotates and slips on the rotating roller, thereby reducing the force of the telescopic gate drive frame to continue to move forward.

[0015] The triggering component is configured so that when the telescopic gate drive frame continues to move forward, the first push rod continues to move and presses against the arc-shaped top block, causing the second trigger block to contact the first trigger block. This activates the alarm light circuit and sounds an alarm, thus reminding the operator to shut down the drive equipment inside the telescopic gate drive frame in time to avoid collision damage caused by continued operation.

Detailed Implementation

[0022] 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.

[0023] Example: Refer to Figure 1-5 A telescopic gate buffer device includes a telescopic gate placement base plate 1, a side fixed wall 4 at the top of the telescopic gate placement base plate 1, a telescopic gate drive frame 2 at the top of the telescopic gate placement base plate 1, a drive wheel 3 at the bottom of the telescopic gate drive frame 2, a triangular blocking block 5 installed on one side of the side fixed wall 4 via a wheel buffer energy reduction component, the triangular blocking block 5 being located on one side of the drive wheel 3, a side buffer plate 11 installed on one side of the side fixed wall 4 via a contact buffer component, a trigger component inside the side fixed wall 4, and an alarm light 24 at the top of the side fixed wall 4, with the trigger component connected to the alarm light 24.

[0024] Specifically, the contact buffer assembly includes two push slots 14 formed on one side of the side fixed wall 4. A first push rod 12 and a second push rod 13 are fixedly installed on one side of the side buffer plate 11. The first push rod 12 and the second push rod 13 extend into the two push slots 14 respectively, and each is fixedly installed with a compression spring 15. A telescopic rubber sleeve 16 is fixedly installed on one side of the side buffer plate 11. The telescopic rubber sleeve 16 is connected to the side of the side fixed wall 4. The drive mechanism inside the telescopic gate drive frame 2 operates, which can drive the drive wheel 3 to move, thereby realizing the opening and closing of the telescopic gate. As the telescopic gate operates, The telescopic gate drive frame 2 will approach the side fixed wall 4. Under normal circumstances, the operator can use a remote control or controller to stop the internal drive equipment. If no operation is performed in time, the telescopic gate drive frame 2 will continue to move and come into contact with the side buffer plate 11. A buffer pad can be provided on one side of the side buffer plate 11 to reduce the impact of the collision during the contact process. After the side buffer plate 11 is squeezed, it will drive the first push rod 12 and the second push rod 13 to move and squeeze the compression spring 15. The buffering effect of the compression spring 15 is used to avoid the collision between the telescopic gate drive frame 2 and the side fixed wall 4.

[0025] Specifically, the wheel buffer energy reduction assembly includes an extrusion groove 8 formed on the side of the side fixed wall 4, an extrusion rod 9 fixedly installed on the side of the triangular blocking block 5, one end of the extrusion rod 9 extending into the extrusion groove 8, and an extrusion spring 10 fixedly installed between the end of the extrusion rod 9 and the inner wall of the extrusion groove 8. An arc-shaped slot 6 is formed on the side of the triangular blocking block 5, and multiple rotating rollers 7 are rotatably installed on the arc-shaped slot 6. The drive wheel 3 at the bottom of the telescopic gate drive frame 2 will contact the triangular blocking block 5. After the drive wheel 3 moves, it will push the triangular blocking block 5 to one side. The extrusion rod 9 moves in the extrusion groove 8 and compresses the extrusion spring 10. As the extrusion force increases, the drive wheel 3 will move onto the arc-shaped slot 6. Multiple rotating rollers 7 are provided on the arc-shaped slot 6. When the drive wheel 3 rotates, it rotates on the rotating rollers 7 and cannot generate driving power, thereby reducing the force of the telescopic gate drive frame 2 continuing to move forward.

[0026] Specifically, the triggering component includes an upper slot 17 formed on the inner wall of the top side of the push groove 14. An arc-shaped top block 18 is movably installed in the upper slot 17. The bottom of the arc-shaped top block 18 is located in the push groove 14 and is adapted to the first push rod 12. A first trigger block 22 is fixedly installed on the inner wall of the top side of the upper slot 17. A second trigger block 23 is fixedly installed on the top of the arc-shaped top block 18. The first trigger block 22 and the second trigger block 23 are electrically connected. A guide post 20 is fixedly installed on the top of the arc-shaped top block 18. A guide groove 19 is formed on the inner wall of the top side of the upper slot 17. The top end of the guide post 20 extends into the guide groove 19. A return spring 21 is fixedly installed between the arc-shaped top block 18 and the inner wall of the top side of the upper slot 17. As the telescopic gate drive frame 2 continues to move forward, the side buffer plate 11 continues to move, and the first push rod 12 continues to move, it will squeeze the arc-shaped top block 18. After being squeezed, the arc-shaped top block 18 will move upward, causing the second trigger block 23 to contact the first trigger block 22. The guide post 20 and guide groove 19 can position the arc-shaped top block 18. The reset spring 21 can keep the arc-shaped top block 18 in a constant position and reset it after being squeezed. The alarm light 24 is connected to an external line to achieve circuit connection. The alarm light 24 will sound an alarm, thereby reminding the operator to shut down the drive equipment inside the telescopic gate drive frame 2 in time to avoid collision damage caused by continued operation.

[0027] In use: As the telescopic gate operates, the telescopic gate drive frame 2 will approach the side fixed wall 4. If it is not closed in time, the telescopic gate drive frame 2 will contact the side buffer plate 11. The compression spring 15 provides a certain buffering effect to prevent the telescopic gate drive frame 2 from colliding with the side fixed wall 4. At this time, the drive wheel 3 at the bottom of the telescopic gate drive frame 2 will contact the triangular blocking block 5. The compression spring 10 also provides a buffering and blocking effect. As the compression force increases, the drive wheel 3 will move onto the arc-shaped groove 6. The drive wheel 3 will rotate and slip on the rotating roller 7, reducing the force of the telescopic gate drive frame 2 continuing to move forward. After the telescopic gate drive frame 2 continues to move forward, the first push rod 12 continues to move and compress the arc-shaped top block 18, causing the second trigger block 23 to contact the first trigger block 22. The alarm light 24 is connected to an external line to achieve circuit connection. The alarm light 24 will sound an alarm, thereby reminding the operator to close the drive equipment inside the telescopic gate drive frame 2 in time to avoid collision damage caused by continued operation. It is easy to use.
