Description

Technical Field

[0001] The utility model relates to the technical field of window components, in particular to a special pulley for a side-pressure sliding window. Background Art

[0002] The door and window translation pulley assembly is a translation assembly that is set between the window body and the window frame and between the sliding door and the door frame to assist in sliding. The traditional door and window translation pulley assembly, including the current one, needs to be adjusted during installation and use. In addition, the adjustment screws are on both sides, so that the assembly cannot be continuously connected and used like a train. In addition, most common hardware parts use screws to adjust the upper wheel, which is very dangerous in high-altitude operations, and if it is not in place after adjustment, it needs to be reworked frequently because it is not easy to clearly see the specific position of the screws during high-altitude operations.

[0003] In the related technology, a solution of the door and window translation pulley assembly (announcement number: CN218787061U) was found after searching. When in use, static friction is improved to dynamic friction, which further reduces the friction force. The two displacement components are set so that the slider moves more smoothly along the trajectory of the displacement guide groove when the pull rod is pulled, making it smoother and more labor-saving to close the window; the outer frame moves with the help of the rotation between the guide rail copper sleeve and the copper sleeve shaft pin, and the base plate B moves on the surface of the copper shaft through the mounting portion B, and moves with the help of lubricating grease, which can also reduce the friction of the movement and make the longitudinal displacement smoother.

[0004] However, since there are two sets of copper shafts and guide rail copper sleeves, the outer frame and lubricating shell may get stuck during movement, reducing the probability of smoothness. The movement may also be unstable, causing the outer frame and lubricating shell to get stuck on the surface of the copper shaft and guide rail copper sleeve, which requires operators to repair, resulting in inconvenience in use and reduced smoothness. In view of this, we have introduced a pulley specifically for side-pressure sliding windows. Summary of the invention

[0016] The inner shell of the slide rail is slidably connected to the surface of the four translation rivets, so that the four translation rivets can make the sliding connection of the inner shell of the slide rail more stable and avoid the situation of movement jamming. The roller will slide on the window frame, so that the sliding of the outer shell of the slide rail is smoother, reducing noise and forming a sound insulation effect.
