Description
Technical field
The utility model relates to a kind of pulley gear, especially for the adjustment height pulley gear of indoor door and window.
Background technology
At present the door and window trolley that uses generally is direct being installed in below the door and window below by connecting axle at door and window, the weight of moving-members such as door and window is pressed on the pulley, on ground or windowsill, slide, this simple in structure, if but out of plumb such as metope, door and windows etc. just can not closely cooperate with metope, leave the slit, neither attractive in appearance, also dangerous, in addition when pulley slides in orbit, if track injustice, because pulley is to fixedly connected with door and window, the pulley that then carries door and window weight is easy to bring unnecessary trouble owing to the vibration of jolting de-orbits to use.
The utility model content
The purpose of this utility model provides a kind ofly can be adjusted by the certain altitude of door and window that pulley supports and the adjustment height pulley gear of vibration derailing when avoiding the pulley operation.
For achieving the above object, the utility model institute by the following technical solutions: the adjustment height pulley gear comprises pulley, wheel seat, described wheel seat are positioned at below the wheel flap, by axle fifth wheel flap and wheel seat, the other end of wheel seat links to each other with pulley, between wheel flap and wheel seat adjusting device is arranged.
Technique scheme can also be done further improvement by following technical measures:
Adjustment height pulley gear, its wheel seat pass through down, and wheel seat links to each other with pulley.
Adjustment height pulley gear, its described adjusting device be for establishing the adjustment piece between wheel flap and the wheel seat, one of screw rod with adjust piece on be threaded, the other end with take turns flap and contact.
The adjustment height pulley gear is being adjusted on piece and the wheel seat contact surface towards the position of pulley, has spring to be located at above the wheel seat and to take turns between the flap.
Above-mentioned adjustment height pulley gear, its described part of taking turns flap for moving articles such as door or windows also can be independent structure.
Above-mentioned adjustment height pulley gear, its end of adjusting piece with contact above the wheel seat, contact position leaves a vertical direction.
Above-mentioned adjustment height pulley gear has a projection on its wheel seat, adjust piece and contact simultaneously with the upper surface of projection and wheel seat.
The beneficial effects of the utility model are: can adjust certain height according to mode of occupation such as door and windows, door and window can be close to metope when moving to metope, can guarantee that in addition the pulley that supports door and window is not easy owing to the vibration of jolting de-orbits.
Description of drawings
Fig. 1 is the stereogram of the utility model adjustment height pulley gear
Fig. 2 is an A-A cross-sectional view among the utility model Fig. 1
Fig. 3 is that the utility model adjustment height pulley gear is installed on the use schematic diagram on the door
Among the figure: 1, pulley; 2, wheel seat; 3, following wheel seat; 4, wheel flap; 5, axle; 6, adjust piece; 7, screw rod; 8, spring; 9, screw; 10, projection; 11, door; 12, metallic supports
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described:
As Fig. 1 of the present utility model, structural representation shown in Figure 2, wheel seat 2 is connected by the wheel flap 4 of axle 5 with the cuboid of at least one end opening, then wheel seat 3 usefulness axle and wheel seat 2 flexibly connect down, identical movement connects a pair of pulley 1 below following wheel seat, between wheel seat 2 and wheel flap 4, be provided with and adjust piece 6, screw rod 7 is connected with adjustment piece 6 by the screw thread of adjusting above the piece, adjust screw rod by screw 9, drive the angle of adjusting piece 6 and wheel seat 2, owing on the wheel seat 2 projection 10 is arranged, and adjusting piece contacts with projection 10 and another face on the wheel seat 2 simultaneously, change the angle of adjusting piece 6 and wheel seat 3 and just can adjust the position of wheel seat 2 with respect to the wheel flap, the adjusting device of forming by screw rod 7 and adjustment piece 6 among certain figure, also can adopt as the adjustment piece of changing different length and realize, or adopt adjust piece above directly change its length with screw rod mode realize, these variations all are the scopes of this patent, all can realize same purpose, as long as wheel seat 2 and the vertical force direction that is subjected to of taking turns flap 4 connecting axles 5 are left in its position, adjusting piece 6 and wheel seat 2 position contacting peripheral hardware springs 8, one end of spring 8 is connected with wheel flap 4, one end is connected with wheel seat, after wheel seat 2 is upspring owing to track jolts when using, because the elastic force effect of spring 8, guarantee that following pulley 1 contacts with track, can not derail.
Adjustment height pulley gear after the assembling can be as shown in Figure 3, the both sides installing enters inside below door 11, the adjustment height pulley gear can add metallic supports with the top that door contacts, to strengthen the holding capacity at this position, take turns flap certainly and also can directly use space that a top panel surrounds as wheel flap 4 installing adjustment height pulley gears.
Use this patent adjustment height pulley gear to adjust certain height, door and window can be close to metope when moving to metope, can guarantee that in addition the pulley that supports door and window is not easy owing to the vibration of jolting de-orbits according to mode of occupation such as door and windows.
