Description

Technical Field

[0001] This utility model relates to a linkage anti-jumping wheel, specifically an adjustable anti-jumping wheel used for installation on doors, windows and guide rails. Background Technology

[0002] In daily life, sliding doors and windows are often installed using adjustable pulleys. Installing sliding doors and windows with adjustable pulleys allows them to move more smoothly depending on the installation environment. However, the traditional linkage anti-jumping pulley structure has a poor load-bearing capacity. After long-term use, the loosening of the adjustment structure can cause the sliding doors and windows to move less smoothly or even damage them. Utility Model Content

[0003] The purpose of this utility model is to provide a linkage anti-jumping wheel. Its large wheel adopts strip-shaped sliding hole orientation, and the small wheel adopts deflection plate orientation. The offset of the large and small wheels can be adjusted by adjusting screws of short and long plates, so as to achieve the purpose of convenient adjustment and strong load-bearing capacity.

[0004] The technical solution of this utility model is based on a shell, a short adjusting plate, a large wheel, a long adjusting plate, a deflection plate, a small wheel, a short adjusting screw, a long adjusting screw, and the large wheel mounted on the short adjusting plate and the small wheel mounted on the deflection plate. The key feature is that the top of the shell has a strip-shaped sliding hole, a first window, and a second window sequentially arranged from the left end to the middle. A rivet is provided at the bottom left end of the short adjusting plate, which is installed on the top left end of the shell, and the rivet is inserted into the strip-shaped sliding hole, allowing the short adjusting plate to slide left and right along the hole. The right end of the short adjusting plate is bent vertically downwards, passing through the first window and extending into the shell. Two through holes are provided on the left side of the shell, and one end of the short adjusting screw passes through one of the through holes on the left side of the shell and connects with the short adjusting plate. The right end of the section plate is vertically bent and connected by threads; the long adjustment plate is installed on the top right end of the outer shell. The top right end of the long adjustment plate has an inclined sliding hole and a strip-shaped through hole from left to right. The deflection plate is installed on the top of the long adjustment plate by a rivet passing through the strip-shaped through hole of the long adjustment plate and the top of the outer shell. The deflection plate can rotate along the rivet and is installed on the top of the long adjustment plate. The bottom of the deflection plate has a boss at the position corresponding to the inclined sliding hole of the long adjustment plate. The boss is inserted into the inclined sliding hole. The middle of the long adjustment plate is inclined and bent through the second window and extends into the outer shell. Then it extends horizontally to the left end of the outer shell. The left end of the long adjustment plate is vertically bent downward. One end of the long plate adjustment screw passes through another through hole on the left side of the outer shell and is connected to the left end of the long adjustment plate vertically bent section by threads.

[0005] The working principle of this utility model is that when the two screws of the short and long plate adjusting screws rotate forward and backward, through their threaded connection with the short and long adjusting plates, the short and long adjusting plates are forced to move left and right along the strip-shaped sliding hole of the outer shell and the strip-shaped through hole of the long adjusting plate, respectively, to adjust their positions. When the long adjusting plate moves left and right, the deflection plate also rotates forward and backward under the action of the boss at the bottom of the deflection plate and the inclined hole of the long adjusting plate. Through the above actions, the linkage anti-jump wheel achieves the function of adjusting the position of the large and small wheels in the longitudinal and transverse directions, while enhancing the load-bearing capacity and anti-loosening ability of the structure.

[0006] The advantages of this utility model are simple structure, convenient adjustment, strong load-bearing capacity, not easy to loosen the structure, and long service life. Attached Figure Description
