Embodiment 1

[0029] like Figure 1 to Figure 4 As shown, the wheel body 10 of a door and window pulley provided by the embodiment of the present invention includes a bearing 11, a buffer ring 12 and a rigid ring 13 that can be in contact with the guide rail. The inner side of the buffer ring 12 is connected to the outer side of the bearing 11. , the rigid ring 13 is separated from the outside of the bearing 11 by the buffer ring 12, that is, the rigid ring 13 is not in direct contact with the bearing 11, the rigid ring 13 is sleeved on the buffer ring 12, and / Or, part of the rigid ring 13 is embedded inside the buffer ring 12, that is, the rigid ring 13 can be entirely sleeved outside the buffer ring 12, and the rigid ring 13 can also be partially exposed, and the exposed part of the rigid ring 13 can be used to contact with the guide rail , part of the rigid ring 13 can be embedded in the buffer ring 12, which is more conducive to the buffer ring 12 to disperse the load of the rigid ring...

Embodiment 2

[0049] like Figure 5 to Figure 8 As shown, the wheel body 10 of a door and window pulley provided by the embodiment of the present invention includes a bearing 11, a rigid ring 13, and a buffer ring 12 arranged between the bearing 11 and the rigid ring 13. The buffer ring 12 The inner side of the buffer ring 12 is connected to the outer side of the bearing 11 , and the outer side of the buffer ring 12 is connected to the inner side of the rigid ring 13 . By adopting the rigid ring 13 and setting the buffer ring 12 between the rigid ring 13 and the bearing 11, the rigid ring 13 can effectively prevent the wheel body 10 from being deformed under pressure, and the buffer ring 12 can play the role of cushioning and silence, and its doors and windows can In the case of long-term use and without sliding for a long time, the wheel body 10 can still slide smoothly, without a sense of blockage or abnormal noise, and the use experience is good.

Abstract

The invention is applicable to the technical field of door and window accessories, and discloses a pulley body of a door and window pulley and a door and window pulley. The pulley body of the door andwindow pulley comprises a bearing, a rigid ring and a buffering ring arranged between the bearing and the rigid ring, wherein the inner side of the buffering ring is connected with the outer side ofthe bearing, and the outer side of the buffering ring is connected with the inner side of the rigid ring. The door and window pulley comprises a base and a connecting shaft, and also comprises the pulley body, wherein the connecting shaft penetrates through the bearing of the pulley body and is connected with the base. According to the pulley body of the door and window pulley and the door and window pulley, the pulley body is provided with the rigid ring and the buffering ring is arranged between the rigid ring and the bearing, so that the door and window can still slide smoothly without sense of blocking and without abnormal noise under the situation of long-term use and non-sliding for a long time, so that the use experience is excellent, and the defects that the existing plastic pulleyis easy to integrally deform or to generate local indentation under the pressure, the metal pulley is high in cost and is non-restorable after deformation and loud in noise can be overcome.

Description

technical field [0001] The invention belongs to the technical field of door and window accessories, in particular to a wheel body of a door and window pulley and the door and window pulley. Background technique [0002] There are many door and window pulleys between the pull-type doors and windows and the door and window frames to reduce resistance and facilitate pushing and pulling. There are two types of conventional door and window pulleys: plastic pulleys and metal pulleys. The plastic pulley is composed of a bearing and a plastic outer ring covering the bearing. The load-bearing performance of the plastic pulley is poor, especially in the case of long-term static load-bearing, the plastic outer ring is easily deformed or partially indented under pressure, resulting in Unsmooth sliding of doors and windows, beating and abnormal noise. The metal pulley is composed of a bearing and a metal outer ring outside the bearing. Although the metal pulley is not easy to produce i...
