Abstract

The utility model discloses a gap automatic regulation pulley of a partition door, which comprises guide pulleys and a fixing rack. The utility model is characterized in that the pulley is also comprises an elastic device, a rotation holding sheet and a first fixing device, and at least one guide pulley is connected with the active end of the rotation holding sheet. The other end of the rotation holding sheet is fixed on the fixing rack by the first fixing device, and the rotation holding sheet can rotate freely around the first fixing device within a certain angle. One end of the elastic device is fixed on the fixing rack by a second fixing device, and the other end is connected with the rotation holding sheet. The elastic device is a spring plate or a spring. With such a project, when deviation of the gap size of an inner frame of a slide groove occurs, two wheels of the device expand and shrink under the action of the spring plate or the spring to act a regulating function, which causes the outer edge of the wheels to abut against the inner frame of the guide side groove and causes the door to keep stable in action.

Description

The partition door top sheave in a kind of automatic adjusting gap

[technical field]

The utility model relates to the partition door top sheave in a kind of automatic adjusting gap.

[background technology]

The directive wheel of existing sliding door all is to be fixed on the fixed mount, and when the inside casing size of guide runner has deviation slightly, the outward flange of directive wheel just can't be near the inside casing of guide runner, thereby it is not smooth to make that sliding door moves.

[summary of the invention]

The purpose of this utility model is exactly in order to solve above guide runner size deviation to be arranged, and the outward flange of directive wheel provides the partition door top sheave in a kind of automatic adjusting gap near the problem of guide runner.

The utility model realizes that the above-mentioned purpose scheme is: the partition door top sheave in a kind of automatic adjusting gap, comprise directive wheel and fixed mount, it is characterized in that: also comprise elastic device, rotate the retention tab and first fastening devices, have at least a directive wheel to be connected in the movable end that rotates retention tab; The other end of described rotation retention tab is fixed on the fixed mount with first fastening devices, and can freely rotate in certain angle around first fastening devices; Described elastic device one end is fixed on the fixed mount with second fastening devices, and the other end links to each other with the rotation retention tab.Described elastic device is shell fragment or spring.

Owing to adopt above scheme, when the inside casing size of guide runner had deviation in processing or because of long term wear, two wheels hypertonic under the effect of shell fragment or spring on the device played the effect of adjusting, make the inside casing of the outward flange of wheel, make the door held stationary that is in operation near guide runner.

[specific embodiment]

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one, as shown in Figure 1, the partition door top sheave in a kind of automatic adjusting gap, comprise directive wheel 1, fixed mount 2, elastic device 3, rotate the retention tab 4 and first fastening devices 51, wherein directive wheel 1 holds the wheel of (or tape spool does not hold) for tape spool, and elastic device 3 is spring leaf (or spring), and first fastening devices 51 is a pin, the directive wheel of one side is positioned at the movable end that rotates retention tab 4, and the directive wheel of opposite side is fixed on the stator of fixed mount 2; The other end that rotates retention tab 4 is fixed on the fixed mount with pin 51, and can freely rotate in certain angle around pin 51; Be fixed on the stopping means 7 on the fixed mount 2 simultaneously in addition, be positioned at a distance of rotating retention tab 4, be used to limit the maximum magnitude and the elastic device 3 that rotate the retention tab rotation and will rotate retention tab 4 restrictions together within the specific limits; Spring leaf 3 one ends are fixed on the fixed mount 2 with second fastening devices 52, the other end with rotate retention tab 4 and link to each other, make the outward flange of directive wheel 1 near the inside casing of guide runner 6.

As shown in Figure 2, the spacing of this device two-wheeled when free state is A, when the inside casing spacing dimension of guide runner 6 has deviation, two wheels hypertonic under the effect of spring leaf on the device, play the effect of adjusting, make the inside casing of the outward flange of wheel, make the door held stationary that is in operation near guide runner 6.

Directive wheel can be fixed on the movable end that rotates retention tab with fastening devices, and elastic device can be positioned at the inboard or the outside of rotating retention tab, makes two directive wheel hypertonics by the mode that stretches.

First and second fastening devices can be immobilising device commonly used such as screw, bolt, pin, rivet.

Shown in Fig. 6 a, 6b, directive wheel can hold 8 wheel or the wheel that holds of tape spool not with tape spool, it all is an integral body that the wheel of the wheel of bearing 8 and no bearing is arranged, and difference is: the wheel that bearing is arranged is that the inner ring of injection moulding and bearing is fixed dead and by the bearing rotation on the outer ring of bearing; And the wheel that does not have bearing be roller endoporus with the axle the gap rotate, in this structure the friction relatively large.Do not have the wheel of bearing simultaneously and have the fixed form of the wheel of bearing to distinguish to some extent yet: between the endoporus of no bearing wheel and the fixed axis certain clearance is arranged; Shown in Fig. 5 b, having between the bearing inner race of bearing wheel and the fixed axis is interference fit, and promptly inner ring is fixed dead.

Shown in Fig. 7 a, 7b, elastic device can be spring or spring leaf.

Embodiment two, as shown in Figure 3, are with the difference of embodiment one, and two directive wheels all are contained in and rotate on the retention tab 4.

Embodiment three, as shown in Figure 4, is with the difference of embodiment one, and the place ahead that is positioned at fixed mount 2 of two directive wheels, another is positioned at the rear of fixed mount 2.(described the place ahead, rear are the front and back with regard to directive wheel installation site relative direction)

Embodiment four, as shown in Figure 5, are with the difference of embodiment one, and two directive wheels 1 all are contained in and rotate on the retention tab 4; Be with the difference of embodiment two, the place ahead that is positioned at fixed mount 2 of two directive wheels, another is positioned at the rear end of fixed mount 2.
