Abstract

The utility model discloses an upper pulley device of a sliding door. The upper pulley device of the sliding door comprises a support, a pulley carrier, pulleys and springs. The pulleys are installed inside a cavity groove in the pulley carrier. The pulley surfaces of the upper portions of the pulleys penetrate out of the pulley carrier through pulley holes. The pulley carrier is movably connected in a cavity groove in the support. Guiding holes in the pulley carrier are sleeved with guiding columns fixed on the support. The springs are arranged on the guiding columns. The two ends of each spring are abutted against the support and the inner bottom wall of the cavity groove in the pulley carrier respectively. Installation holes are formed in the support. The pulleys or the pulley carrier is pressed, and the pulleys and the pulley carrier can both descend synchronously by compressing the springs. According to the scheme, the technical defect that in the prior art, when an existing upper pulley device of the sliding door is used, the clamping action on a door leaf in the vertical direction is lacked is overcome, and the problems that due to the defect, the door leaf is easily disassembled by people, and the door loses the anti-theft efficacy are solved.

Description

The top sheave device of sliding door

Technical field:

The utility model relates to pulley gear, relates in particular to the top sheave device of sliding door.

Technical background:

existing sliding door adopts shape to make doorframe basically, with shape and glass, make door leaf, effect in conjunction with pulley gear and guide rail, make door leaf in doorframe, move and to reach out flexibly, the purpose of closing the door, sliding door is a kind of in existing sliding door, it is characterized in that the upper of door leaf, below all needs to install pulley gear, but only have the pulley of below to use in conjunction with guide rail, when the pulley of top uses, by the elastic component in pulley gear, wheel face is conflicted on the internal groove side wall of the concave character type section bar as lintel, play and hold up steady door leaf top in order to avoid inside and outside when mobile, rock and be convenient to mobile effect, as everybody knows, the cover resultant of its below pulley of the door of in fact this structure and guide rail, little more a lot of from the spacing of lintel internal groove bottom than top pulley gear or door leaf top far away, even if make door leaf height by the adjustment screw in lower pulley apparatus, increase the cover resultant between door leaf top and lintel, also be difficult to that above-mentioned spacing is narrowed down to door leaf and held up artificially the degree of laying down, so there is the not satisfactory problem of anti-theft feature in existing sliding door.

Analyze after deliberation, cause the reason of sliding door the problems referred to above, be that mainly top sheave device of the prior art lacks the clamping action of in the vertical direction, in namely installing and using, existing pulley gear does not have corresponding member or structure, can retrain on door leaf to move on to and may make the below pulley break away from the displacement of slide rail, so as not to cause door leaf by the people for moving away from.

The utility model content:

In order to address the above problem, the utility model is to provide a kind of top sheave device of sliding door, and compared with prior art, the pulley in corresponding device can be along the guide pillar lifting under the effect of power, the wheel both sides of its pulley are inclined-plane and middle part projection, and its technical scheme is as follows:

A kind of top sheave device of sliding door, contain bearing, wheel carrier, pulley and spring, and described pulley contains the axle that is enclosed within bearing, and be fixed on the rubber tire that bearing is placed outward; Described pulley is arranged in the chamber groove of wheel carrier, the top wheel face passes outside wheel carrier in the wheel hole, described wheel carrier work is connected in the chamber groove of bearing, be fixed in the guide hole of guide column sleeve on wheel carrier on bearing, on guide pillar, be placed with spring, the two ends of spring withstand on respectively on the interior diapire of described bearing and wheel carrier lumen groove, on described bearing, are provided with installing hole.

The bottom land middle part of above-mentioned bearing is provided with strip hole, the length in hole is greater than the ultimate range between two its wheel faces of pulley installing on wheel carrier, purpose is when pulley forced belt driving wheel frame is descended, and in the Neng Zaigai hole, bottom of pulley, passes and with the bottom land of bearing, does not touch;

The front/back cavity wall symmetry of above-mentioned wheel carrier, middle part are down " protruding " word shape, and high spot is provided with bar hole;

On the front/back cavity wall of above-mentioned bearing, be symmetrically arranged with connecting hole;

The wheel face both sides of described rubber tire are inclined-plane, are " eight " word shape and distribute, and the middle part projection, its objective is after wheel face is engaged in identical shaped rail groove, play steady, door leaf top, the location effect that does not rock front and back in movement of holding up;

Above-mentioned wheel carrier work is connected in the chamber groove of bearing and refers to after cover upper spring on described guide pillar, wheel carrier is packed in the chamber groove of bearing, make the guide pillar top pass described guide hole, and described bar hole is alignd with connecting hole and with rivet, pass and rivet afterwards, after connecting, press pulley or wheel carrier, all can pulley and wheel carrier synchronously be descended by Compress Spring.

during use, by the installing hole on described bearing with screw by the fixing top of door leaf of this device, before installation, need on the door leaf top section bar at pre-installation position, leave a room corresponding with described strip hole, in order to avoid pulley forced belt driving wheel frame is while descending, the bottom of pulley and door leaf top section bar are touched, after in door leaf is arranged on doorframe, by regulating lower pulley apparatus, door leaf is raise, so that the pulley in described device is subjected to drops, when the wheel face peak drops to distance from described guide pillar top less than the cover resultant of lower sheave and its guide rail, described device just can be realized the clamping action to the door leaf in the vertical direction, under this state, can stop and artificially door leaf be laid down, if its principle is to hold up door leaf this moment, to cause in described device pulley again forced belt driving wheel frame synchronously descend, when the wheel face peak drops to the guide pillar top and can contact upper rail, decline is obstructed, that is to say that this moment, door leaf arrived the peak that is held up rising, regulating action due to front, under this height, lower sheave does not break away from the fit with lower guideway, so door leaf unloads, unless adjust the adjustment screw in lower pulley apparatus with screwdriver, its pulley is raise to be separated with guide rail, but as everybody knows, this operation can only (refer to be positioned at that indoor side) and carry out in door, the illegal chamber entrant who is positioned at outdoors can not do this operation.

The beneficial effects of the utility model are: the top sheave device that has solved prior art is deposited in use, the technological deficiency that the door leaf in the vertical direction is lacked to clamping action, made up because of this defect cause door leaf easily by the people for laying down, make to lose the problem of antitheft effect.
