Abstract
The utility model discloses an elastic three-wheel for push-pull door, which comprises three pulleys which are arranged in a shape similar to the Chinese character 'pin', wherein the upper pulley is connected with a movable shaft of a pulley fixed wheel rack, and a spring is installed in the movable shaft of the pulley fixed wheel rack, which enables the elastic three-wheel to automatically adjust the relative position between the upper pulley and the lower pulleys, and guarantees a movable door not to bounce during the push-pull process, thereby reducing the noise, enabling the push-pull to be stable and smooth, improving the use convenience and stability of movable doors, and prolonging the service life.
Description
Technical field
The utility model relates to a kind of pulley, more particularly, relates to a kind of elasticity three-wheel that is used for sliding door.
Background technology
Sliding door adopts the structure of track and roller combination usually, utilizes to be installed on roller in the chute of track and to make it to roll and reach the purpose that promotes sliding door easily.At present, the normal connected mode that adopts of roller is that two rollers with certain distance are installed on support, and these two pulleys are installed among the chute of track.Because the distance between two rollers is fixed, and the chute width of track is also determined, therefore be difficult to coupling fully between the two, thereby cause sliding door to move reposefully, and integral body can produce usually and rocks and produce noise.Rock the safety that also can influence sliding door for a long time, and reduce the application life of sliding door.
As a kind of improvement project, a kind of sliding door top sheave device is disclosed in the patent No. is the Chinese utility model patent of ZL02247757.8, this device has adopted at least three pulleys, comprising at least one fast pulley and two elastic wheels, and be provided with a framework, fast pulley is hubbed on this framework, and elastic wheel is hubbed on the framework by " L " type rack elasticity.Because support adopts elastomeric material, thereby the distance between fast pulley and the elastic wheel can be regulated automatically.Although this improvement project can make the match ratio prior art between the chute of roller and track tightr to a certain extent, but wherein the use of elastomeric material causes having improved the requirement to material and technology, thereby makes that the complex structure of whole sliding door, cost raise, production efficiency reduces.In addition, the problem that elastomeric material also exists elastic deformation to be limited in scope is added and is worn out comparatively fast, and its self-regulating effect is also not fully up to expectations.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model provides the automatic adjusting position of a kind of energy so that the elasticity three-wheel of sliding door even running.
For achieving the above object, the utility model provides a kind of elasticity three-wheel that is used for sliding door, comprise that is gone up a wheel, two lower whorls, pulley is wheel carrier fixedly, pulley is the wheel carrier movable axis fixedly, the pulley holder, pulley is flap fixedly, connecting screw, wherein, described one go up wheel and pulley fixedly the wheel carrier movable axis be connected, described two lower whorls respectively with the pulley of correspondence fixedly wheel carrier be connected, pulley fixedly wheel carrier and pulley is installed on the pulley holder after fixedly being connected by connecting screw between the wheel carrier movable axis, so that a last wheel and two lower whorls are lined up " product " font, pulley holder and pulley fixedly flap link together by bolt, and pulley fixedly wheel carrier movable axis inside is equipped with spring.
According to a preferred embodiment of the present utility model, two rubber cushions that fixedly can also be provided for fixing dodge gate between the flap and reduce to impact at pulley holder and pulley.
According to another preferred embodiment of the present utility model, can also be provided for regulating the fixedly set screw of the relative position between wheel carrier and the pulley holder of pulley on the pulley holder.
The beneficial effects of the utility model are, at pulley fixedly under the effect of the spring of wheel carrier movable axis inside, this elasticity three-wheel has elasticity, make the relative distance that goes up between wheel and the lower whorl to regulate automatically, thereby can guarantee that not only pulley can not come off in running from the chute that gets on the right track, safety is firm more to make dodge gate, but also can guarantee that the elasticity three-wheel fully contacts with the chute that gets on the right track in the operation overall process, dodge gate can not beated when push-and-pull, noise is reduced, the push-and-pull steady and smooth, and improved convenience and stability that dodge gate uses, also prolonged application life simultaneously.
Description of drawings
Fig. 1 is the structural representation according to the elasticity three-wheel of a preferred embodiment of the utility model; And
Fig. 2 is the scheme of installation of elasticity three-wheel shown in Figure 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 and Fig. 2 show the concrete structure according to the elasticity three-wheel of the utility model preferred embodiment jointly.As shown in FIG., this elasticity three-wheel comprises fixedly fixing fixedly flap 9, connecting screw 10 and the spring 11 of wheel carrier movable axis 5, pulley holder 6, set screw 7, rubber cushion 8, pulley of wheel carrier 4, pulley of wheel 2, lower whorl 3, pulley, wherein, last wheel 2 and pulley fixedly wheel carrier movable axis 5 are connected, two lower whorls 3 respectively with the pulley of correspondence fixedly wheel carrier 4 be connected, pulley fixedly wheel carrier 4 and pulley fixedly is connected by connecting screw 10 between the wheel carrier movable axis 5.The pulley fixedly inside of wheel carrier movable axis 5 is equipped with spring 11, together is installed on the pulley holder 6 then, so that three pulleys are lined up " product " font.At last, can by bolt pulley holder 6 and pulley fixedly flap 9 link together.
As further improvement, in the present embodiment, fixedly can also be provided with two rubber cushions 8 between the flap 9 at pulley holder 6 and pulley, be used for fixing dodge gate 12, and reduce to vibrate the impact that brings.In addition, on pulley holder 6, can also be provided with set screw 7, be used to regulate the fixedly relative position up and down between wheel carrier 4 and the pulley holder 6 of pulley, to reach the effect of regulating dodge gate 12 height and balances.
From Fig. 2, can also see, be preferably used for getting on the right track in 1 of shower house sliding door according to the elasticity three-wheel of present embodiment.At pulley fixedly under the effect of the spring 11 of wheel carrier movable axis 5 inside, this pulley has elasticity, relative distance between last wheel 2 and the lower whorl 3 can be regulated automatically, thereby make wheel 2 more closely abut in the upper edge of the 1 chute inboard of getting on the right track, the while, two lower whorls 3 more closely abutted in the lower edge of the 1 chute inboard of getting on the right track.Like this, guaranteed that not only pulley can not come off from 1 the chute of getting on the right track in running, safety is firm more to make dodge gate 12, and guaranteed that the elasticity three-wheel fully contacts with 1 the chute of getting on the right track in the operation overall process, make dodge gate 12 when push-and-pull, can not beat, thereby noise is reduced, the push-and-pull steady and smooth, improve convenience and stability that dodge gate 12 uses, and prolonged application life.
Certainly, this elasticity three-wheel is not limited to be applied in the getting on the right track of shower house sliding door, at the elasticity three-wheel that similarly all can adopt the utility model to provide in other track with its structure.
More than disclosed only be preferred embodiment of the present utility model, can not limit rights protection scope of the present utility model with this certainly.Be appreciated that the equivalent variations of doing according to essence that limits in the claim of the present utility model and scope, still belong to the scope that the utility model is contained.
