Description

TECHNICAL FIELD

[0001] The utility model relates to door and window accessory technical field, concretely relates to reliable wear -resisting side pressure pulley assembly. BACKGROUND

[0002] The part provided in this part is merely background information related to the present application to facilitate those skilled in the art to understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] At present, some push-pull doors and windows that can realize side pressure sealing appear on the market, and such doors and windows can be gradually moved to the door frame direction through the rotation of the handle after being slid closed, and the sealing strip on the door and window is tightly pressed on the door frame, so that the sealing property of the door and window when being closed is improved. In order to realize the side movement of the door and window, a side pressure pulley assembly needs to be installed at the bottom of the door and window.

[0004] The existing push-pull side pressure pulley generally comprises a sliding seat installed at the bottom of the door leaf, a pulley frame in sliding cooperation with the sliding seat, and a guide pulley arranged on the pulley frame. The pulley frame is provided with a guide groove, which is used for sliding and clamping cooperation with the clamping block on the transmission bar. Thus, when the transmission bar is driven to slide, the sliding seat and the pulley frame can be driven to relatively side move through the sliding and clamping cooperation of the guide groove and the clamping block, so as to drive the door leaf to side move.

[0005] However, it is found in the use process that, since the pulley frame is made of zinc alloy material, the guide groove is directly formed on the pulley frame, and the surface thereof is relatively rough. When the clamping block on the transmission bar slides in the guide groove, the friction force received by the clamping block is relatively large, which not only causes the sliding to be blocked, but also causes the clamping block to be worn. With the passage of time, the parts will be scrapped, and the service life of the product is greatly reduced. UTILITY MODEL CONTENTS
