Pulley connecting structure used for guide rail elevator and guide rail elevator comprising pulley connecting structure

Abstract

The invention discloses a pulley connecting structure used for a guide rail elevator and the guide rail elevator comprising the pulley connecting structure. The pulley connecting structure comprises an upper guide rail, a cylindrical boss assembly, a metal ring, a pulley and a self-tapping screw A. The cylindrical boss assembly is fixed to the top of the upper guide rail and comprises a boss baseand a cylindrical boss fixed to the center of the boss base. A plurality of supporting ribs which are arranged around the cylindrical boss are fixed to the boss base of the cylindrical boss assembly.The cylindrical boss of the cylindrical boss assembly is sleeved with the metal ring. The pulley is arranged outside the metal ring in a running fit mode. A screw hole A is formed in the cylindrical boss of the cylindrical boss assembly. The self-tapping screw A is mounted in the screw hole A in the cylindrical boss. The pulley is mounted outside the metal ring in a limited mode through the self-tapping screw. The pulley connecting structure used for the guide rail elevator and the guide rail elevator comprising the pulley connecting structure have the advantages that the structure is simple,the number of part is small, and installation is convenient and fast; and the weight of the pulley connecting structure is effectively reduced, and the pulley connecting structure is in conformity with the lightweight development tendency of automobile.

Description

technical field [0001] The invention relates to the technical field of guide rail lifter pulleys, in particular to a pulley connection structure used on a guide rail lifter and the formed guide rail lifter. Background technique [0002] Such as figure 1 , figure 2 As shown, the upper guide structure of the traditional plastic guide rail glass regulator includes a self-tapping screw B7, a guide wheel shaft 8, a guide wheel 9 and a guide wheel bracket 10, the guide wheel bracket 10 is arranged in parallel with the guide wheel 9, and the plastic guide rail glass regulator has Guide rail, the guide rail includes upper guide rail 11 and lower guide rail 13, the guide wheel shaft 8 passes through the guide wheel 9 in turn, the guide wheel bracket 10 is installed on the upper guide rail 11 of the plastic guide rail glass regulator, and the self-tapping screw B7 passes through the guide wheel shaft 8 in turn , guide wheel 9, guide wheel support 10 are fixed on the top guide rail ...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the upper guide structure of the traditional plastic guide rail glass regulator has the following disadvantages: first, the number of assembly parts is large, the probability of matching failure between the parts is high, and the price of the parts is high; The probability of passing is high, especially when the self-tapping screw B7 is skewed, it will cause the lifter assembly to be scrapped; third, the equipment required for assembly is large, the investment in the production line is high, and the production line occupies a large area; fourth, the assembly accuracy Difficult to guarantee and will reduce elevator operating efficiency
