[0002] As a kind of living furniture, chair is an indispensable furniture in people's daily life. It mainly includes backrest, cushion and chair legs. With the development of society, modern chairs make human Life is more convenient and comfortable, thus just have the chair with pulley, but existing pulley still has certain defect, and existing pulley mostly is a single jumper connected with chair leg by connecting rod, after using for a long time, The gap between the connecting rod and the chair leg becomes larger, so that when in use, a larger noise is emitted, which affects people's normal use, and most of the existing pulleys are made in one piece, so when the wheel is damaged, it needs to be removed. The overall replacement greatly increases the cost of use. For this reason, a pulley is proposed

The pulley comprises a connecting main body and two clamping springs, a first groove is formed in the upper surface of the connecting main body, a first connecting rod is clamped in the first groove, and a second groove and a third groove are formed in the outer side wall of the first connecting rod; the inner side wall of the first groove is clamped in the third groove, a clamping spring is installed on the inner side wall of the second groove, and another clamping spring is installed on the outer side wall of the first connecting rod and located above the second groove. By means of the two clamping springs and the pipe bodies on the first connecting rods, friction between the first connecting rods and the chair legs is increased, so that gaps between the first connecting rods and the chair legs are reduced, noise generated during operation of the chair is reduced, gaps between the third connecting rods and the wheels are tensioned through the springs, and noise generated during operation of the chair is further reduced.
Description
technical field [0001] The invention relates to the technical field of chair auxiliary appliances, in particular to a pulley. Background technique [0002] As a kind of living furniture, chair is an indispensable furniture in people's daily life. It mainly includes backrest, cushion and chair legs. With the development of society, modern chairs make human Life is more convenient and comfortable, thus just have the chair with pulley, but existing pulley still has certain defect, and existing pulley mostly is a single jumper connected with chair leg by connecting rod, after using for a long time, The gap between the connecting rod and the chair leg becomes larger, so that when in use, a larger noise is emitted, which affects people's normal use, and most of the existing pulleys are made in one piece, so when the wheel is damaged, it needs to be removed. Whole replacement greatly increases the cost of use, for this reason, a pulley is proposed. Contents of the invention [...
