Abstract
Description
Technical Field
[0001] This utility model relates to a press-and-rebound bidirectional buffer roller, specifically a press-and-rebound bidirectional buffer roller that automatically rebounds when pressed. Background Technology
[0002] The buffer rollers used in current door and window installations are designed to provide a buffer when opening and closing doors. After opening, doors and windows are in a buffered closing process when there is no external force. Therefore, if doors and windows need to be kept open, additional components such as door catches are required. However, if the additional components do not adapt well to the rebound force of the buffer rollers, they will often come off. Moreover, the additional components have poor adaptability to the installation environment. Alternatively, if the opening and closing of the door is triggered by the collision of the buffer roller's sliding latch, the latch will be hit on both sides. Since the trigger position is usually designed with an angle, being hit on both sides will easily damage the trigger position. Summary of the Invention
[0003] The purpose of this utility model is to provide a press-and-rebound bidirectional buffer wheel. Under the action of the return tension spring being greater than that of the buffer spring, the rebound hook slides out of the arc section of the slide groove when the buffer wheel is pressed, thereby pushing the inner slide frame to drive the buffer hook A, buffer hook B, and rebound hook to slide out of the arc section of the slide groove, thus completing the press-and-rebound bidirectional buffer wheel press-and-rebound action.
[0004] The technical solution of this utility model is based on the main frame of the chute, tail wheel, load-bearing wheel, return tension spring, buffer spring, traction rope, guide wheel, buffer hook A, buffer hook B, inner slide, rebound hook, buffer hydraulic cylinder, and pin. Its features include the tail wheel and load-bearing wheel being installed at the left and right ends of the main frame of the chute, respectively; chute tracks are provided on the left, middle, and right sides of the front and back of the main frame of the chute; the left ends of the left and right chute tracks are curved downwards, and the right end of the middle chute track is also curved downwards; buffer hooks A and B are respectively installed on the left and middle chute tracks; and the left and right sides of the buffer springs... The inner slide is connected to buffer hook A and buffer hook B respectively; the inner slide is installed inside the main frame of the slide, the left end of the inner slide is connected to the right end of buffer hook A, and the right end extends to the slide on the right side of the main frame of the slide and is installed on the slide by a pin; a frame is set at the position opposite to the right slide of the main frame of the slide, the rebound hook is installed on the right slide of the main frame of the slide and is located inside the frame of the inner slide, the guide wheel is installed on the right side of the main frame of the slide and is located to the left of the load-bearing wheel, the left end of the return tension spring is connected to the top of the tail wheel, and the right end is connected to the left end of the traction rope, and the right end of the traction rope is connected to the right end of the rebound hook after passing through the side guide wheel.
[0005] The spring force of the reset tension spring described in this utility model is greater than that of the buffer spring; the left and right ends of the buffer hydraulic cylinder are respectively connected to buffer hook A and buffer hook B; the top of buffer hook A and buffer hook B are provided with inclined trigger buckles protruding outward from the main frame of the slide groove, and the shape of the rebound hook is V-shaped. The top left of the rebound hook protrudes outward from the main frame of the slide groove with an inclined buckle. After buffer hook A, buffer hook B and rebound hook have slid into the arc end of their respective slide grooves, when the press-rebound bidirectional buffer hanger is pressed and pushed, buffer hook B is triggered by the corresponding buckle on the mounting bracket of the press-rebound bidirectional buffer hanger, so that buffer hook B slides from the opening position of the slide groove to the rebound position, and at the same time drives the inner slide to move towards the rebound hook, so that the inner slide touches the rebound hook, allowing the rebound hook to slide out of the arc section of the slide groove, and the press-rebound bidirectional buffer hanger switches to the closing buffer state, completing the closing action.
[0006] The working principle of this utility model is as follows: when the press-rebound bidirectional buffer roller moves under the action of the door and window, the buffer hooks A, B, and rebound hook protrude to the outside of the main frame of the slide rail and encounter the corresponding parts on the buffer roller mounting bracket during this process, forcing the buffer hooks A, B, and rebound hook to slide into the arc section of the slide rail. When the press-rebound bidirectional buffer roller is pressed and pushed, the buffer hook B is triggered by the corresponding position of the press-rebound bidirectional buffer roller mounting bracket, causing the buffer hook B to slide from the door opening position to the rebound position in the slide rail. At the same time, it drives the inner slide to move towards the rebound hook, so that the inner slide touches the rebound hook. When the rebound hook slides into the arc end of the slide rail, the downward V-shaped groove of the rebound hook contacts the pin. When the inner slide moves to the rebound position and touches the right end of the rebound hook, under the restraint of the pin, the rebound hook slides out of the arc section of the slide rail, allowing the press-rebound bidirectional buffer roller to switch to the door closing buffer state to complete the door closing action.
[0007] The advantages of this utility model are simple structure, stable operation, low noise, and good buffering effect. When the bidirectional buffer roller is pressed and pushed, it can naturally rebound and reset to complete the closing action. Attached Figure Description
