Description

Technical Field

[0001] This utility model relates to the field of telescopic gate technology, specifically a telescopic gate with a shock-absorbing and noise-reducing structure. Background Technology

[0002] A retractable gate is a type of gate whose body can extend and retract freely to control the size of the gate opening and to control the passage of pedestrians or vehicles. In daily life, retractable gates are widely used in factories, schools, residential communities, and other units due to their high degree of flexibility.

Especially after prolonged use, the gate is susceptible to damage from vibration and external impacts, affecting not only its lifespan but also potentially posing safety hazards to users. Therefore, there is an urgent need for a new retractable gate design that can effectively reduce vibration and noise, improve stability and safety, to solve these problems and adapt to more application scenarios.

The movement of the drive wheel 5 causes the telescopic folding frame 6 to unfold or retract, realizing the opening and closing operation of the telescopic gate. During the operation of the telescopic gate, the anti-collision plate 10 provides anti-collision protection. Simultaneously, the design of the reflective strip 15 improves visibility at night. To enhance safety during use, the flashing warning light 2 further strengthens the reminder function to pedestrians and vehicles passing by. When the sliding gate is impacted by an external force, the anti-collision plate 10 is limited by the second limiting slide groove 21 and the second limiting slider 20. The buffer link 11 and the inclined support rod 12 are folded by the force of the anti-collision plate 10. The dampers 22 in the first slide groove 9 and the second slide groove 7 effectively reduce the vibration and noise of the movement of the buffer link 11 and the inclined support rod 12, avoid damage to the gate body, and improve the durability and stability of the overall structure.
