Abstract
Description
Technical Field
[0001] The invention relates to a press-rebound bidirectional buffer hanging wheel, in particular to a press-rebound bidirectional buffer hanging wheel which automatically rebounds when pressed. Background Art
[0002] The buffer wheels used in the installation of doors and windows on the market are all used to provide buffering when opening and closing doors. After the doors and windows are opened, they are in the buffering closing process when there is no external force. When the doors and windows need to be normally open, independent external components such as door suction are required to achieve the normally open state. When the additional components are not sufficiently adaptable to the rebound force of the buffer wheels, they will often be disengaged, and the additional components have poor adaptability to the installation environment, or the door opening and closing are triggered by the collision of the sliding buckle of the buffer wheel to get into or slide out of the slide slot. In this way, the sliding buckle will be collided on both sides. Because the trigger position is generally designed to be inclined, collision on both sides will make the trigger position easy to be damaged. Summary of the invention
[0003] The purpose of the present invention is to provide a press-rebound bidirectional buffer hanging wheel, which, under the action of the elastic force of the reset tension spring being greater than the buffer spring, slides out of the arc section of the slide groove through the rebound hook when the buffer hanging 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, completing the press-rebound bidirectional buffer hanging wheel press-buffer rebound action.
[0004] The technical solution of the present invention is based on a slide main frame, a tail wheel, a load-bearing wheel, a reset tension spring, a buffer spring, a traction rope, a guide wheel, a buffer hook A, a buffer hook B, an inner slide frame, a rebound hook, a buffer hydraulic cylinder, and a pin. The characteristic is that the tail wheel and the load-bearing wheel are respectively installed on the left and right ends of the slide main frame, and slides are respectively arranged on the left, middle, and right sides of the front and back sides of the slide main frame. The left ends of the left and right slides are bent in an arc shape downward, and the right end of the middle slide is bent in an arc shape downward. The buffer hook A and the buffer hook B are respectively installed on the left and middle slides, and the left and right ends of the buffer spring are They are connected with buffer hook A and buffer hook B respectively; the inner slide is installed in the slide main frame, the left end of the inner slide is connected with the right end of buffer hook A, and the right end extends to the slide on the right side of the slide main frame and is installed on the slide through a pin; a frame is provided at the relative position of the inner slide and the right slide of the slide main frame, the rebound hook is installed on the slide on the right side of the slide main frame, and is located in the frame of the inner slide, the guide wheel is installed on the right side of the slide main frame and on the left side of the load-bearing wheel, the left end of the reset 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 elastic force of the reset tension spring described in the present invention 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 tops of the buffer hook A and buffer hook B are both provided with inclined trigger buckles protruding outwards from the main frame of the chute. The shape of the return spring hook is V-shaped, and the left side of the top of the return spring hook protrudes outwards from the main frame of the chute with an inclined buckle. After the buffer hook A, buffer hook B, and return spring hook all slide into the arc-shaped ends of their respective chutes, when the press-and-release double-direction buffer pulley is pressed and pushed, the buffer hook B is triggered by the corresponding buckle on the press-and-release double-direction buffer pulley mounting bracket, causing the buffer hook B to slide from the open position to the return position in the chute, and at the same time driving the inner sliding frame towards the return spring hook, making the inner sliding frame touch the return spring hook, causing the return spring hook to slide out of the arc-shaped section of the chute, and switching the press-and-release double-direction buffer pulley to the closing buffer state to complete the closing action.
[0006] The working principle of the present invention is that when the press-and-release double-direction buffer pulley moves driven by the doors and windows, the parts of the buffer hook A, buffer hook B, and return spring hook protruding out of the main frame of the chute will encounter the corresponding parts on the buffer pulley mounting bracket during this process, forcing the buffer hook A, buffer hook B, and return spring hook to slide into the arc-shaped section of the chute. When the press-and-release double-direction buffer pulley is pressed and pushed, the buffer hook B is triggered by the corresponding buckle on the press-and-release double-direction buffer pulley mounting bracket, causing the buffer hook B to slide from the open position to the return position in the chute, and at the same time driving the inner sliding frame towards the return spring hook, making the inner sliding frame touch the return spring hook. Since when the return spring hook slides into the arc-shaped end of the chute, the downward V-shaped groove of the return spring hook contacts the pin, when the inner sliding frame moves to the return position and touches the right end of the return spring hook, at this time under the limiting action of the pin, the return spring hook slides out of the arc-shaped section of the chute, and the press-and-release double-direction buffer pulley is switched to the closing buffer state to complete the closing action.
[0007] The advantages of the present invention are simple structure, stable operation, low noise, good buffer effect, and can naturally rebound and reset to complete the closing action when the press-and-release double-direction buffer pulley is pressed and pushed. Description of the Drawings
