Abstract

The utility model provides a pulley block comprising a guide wheel, a guide wheel shaft, a door leaf fixed axle and a guide wheel bushing applied on the guide wheel shaft, wherein the door leaf fixed axle is coupled on the guide wheel shaft in the same vertical plane; an outer guide wheel side cover and an inner guide wheel side cover are arranged on both sides of the door leaf fixed axle; the guide wheel shaft is secured and sandwiched between the outer guide wheel side cover and the inner guide wheel side cover. The utility model is provided with the guide wheel and the door leaf fixed axle coupled in the same vertical plane; the pulley block allows no angle deviation in a slide channel movement due to the load of a door leaf provided in place and enables the guide wheel to sustain a uniform load for a smooth slide movement, minimize the wear of the guide wheel and the slide channel due to angle deviation, thereby extending the service life of the pulley block.

Description

A kind of pulley

Technical field

The utility model relates to a kind of pulley, the pulley that uses on particularly a kind of sliding door.

Background technology

In recent years, the utilization of sliding door in the modern house design is more extensive, and gives to design at home and brought aesthetic feeling.On compartment, furniture and integral bathroom, all be widely used.

This sliding door is equipped with pulley and slide rail at two fans or the door leaf bottom more than two fans, make and to slide mutually between door leaf and the door leaf, it is overlapped between door leaf and the door leaf when door is opened, door leaf and door leaf were directly overlapped when door was closed, and had reached combined effect attractive in appearance like this.

But, pulley below the present sliding door and slide rail often damage easily, bring a lot of troubles to the user, its reason is: pulley is generally by guide wheel, guide wheel shaft and the aggregate erection of door leaf fixed axis form, existing mounting means generally as shown in Figure 1, it is enclosed within guide wheel 100 on the guide wheel shaft 200, door leaf fixed axis 300 is located at a side of guide wheel shaft, so, after door leaf being installed on the door leaf fixed axis, owing to the weight reason of door leaf, make guide wheel shaft and on guide wheel can tilt with respect to guide rail, cause the contact area of guide wheel and slide rail to reduce, in sliding process, will cause the not smooth situation of slip, and after repeatedly sliding, because the contact area of guide wheel and slide rail reduces, can cause rapid wearing on the contact surface of pulley and slide rail, finally cause and to use, must change.Bring very big inconvenience to the user.

Summary of the invention

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of pulley of providing, it in use, it is smooth and easy to slide, it is little to wear and tear.

The utility model achieves the above object by following structure:

It includes guide wheel, guide wheel shaft and door leaf fixed axis, and guide wheel is sleeved on the guide wheel shaft, door leaf fixed axis and guide wheel shaft fixed installation, and its improvement is: door leaf fixed axis and guide wheel shaft are positioned on the vertical plane;

In the said structure, door leaf fixed axis both sides are respectively equipped with guide wheel outside lid and guide wheel inner edge lid, and guide wheel shaft is fixed between guide wheel outside lid and the guide wheel inner edge lid;

In the said structure, door leaf fixed axis one face down bonding covers outside connecing and being fixed on guide wheel, and opposite side is fixing with screw and guide wheel inner edge lid;

In the said structure, the guide wheel outside covers and is provided with the guide wheel axis hole, and guide wheel shaft is installed in the guide wheel axis hole, and fixing with screw and guide wheel inner edge lid;

In the said structure, the guide wheel outside covers and is provided with auxiliary door leaf fixed axis, and the guide wheel inner edge covers and is provided with auxiliary door leaf fixed axis locating hole;

In the said structure, be provided with bearing between guide wheel and the guide wheel shaft;

In the said structure, be provided with rubber cushion at guide wheel outside lid and guide wheel inner edge lid inboard.

Owing to adopted said structure, the utility model is being located at guide wheel and door leaf fixed axis on the vertical plane, after door leaf is installed, pulley can be because of the weight of door leaf with respect to the variation of slide rail generation angle, make pulley stressed evenly, remain slip stably with slide rail, farthest reduced pulley and slide rail, prolong the life-span of pulley owing to the wearing and tearing that deviation causes take place.
