Abstract
The utility model mainly discloses a pulley protection sleeve for an aluminum alloy sliding door and window, which comprises a protection sleeve body in a groove body structure, wherein an outward bulge is arranged at a groove bottom of the protection sleeve body; the top of a pulley assembly is clamped into the bulge; the tail ends of groove walls of the protection sleeve body are bent inwards to from hook parts; and the left side and the right side of the pulley assembly are clamped and fixed by the hook parts. The pulley protection sleeve is mounted between a pulley and a profile notch, so that abrasion between the pulley assembly and a profile cavity body is avoided; the service life of the pulley assembly is prolonged; and the pulley is fixed, so that the pulley cannot deviate in the cavity body.
Description
Technical field
The utility model relates to building window component technology field, and is special relevant with a kind of aluminum alloy push-pull window glidewheel protective sleeve.
Background technology
Door and window is one of important component of owned building, mainly comprise flat-open door and window, slide door or window, lifting sliding door, wherein slide door or window is superior performance and economical and practical a product, has perfect detail structure design, having simultaneously light and handy profile, is the ideal chose of large-scale Gongjian's project and housing construction.
Slide door or window comprises door-window section bar and various Hardware fittings etc., and slide door or window is all to carry out open and close with the mode of pulley basically.During installation, pulley assembly is directly to be contained on bar, and in use, between pulley assembly and sash, friction seriously, the problem that pulley assembly damages or switch has some setbacks often occurs.
In order to address the above problem, the inventor designs a kind of aluminum alloy push-pull door and window trolley protective sleeve.
The utility model content
Main purpose of the present utility model is to provide a kind of aluminum alloy push-pull door and window trolley protective sleeve, can guarantee that pulley in use is not offset, and increases pulley application life.In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of aluminum alloy push-pull door and window trolley protective sleeve comprises the protective sleeve body of trough body structure, has outside projection at the bottom land of protective sleeve body, and the pulley assembly top snaps in projection; The cell wall end of protective sleeve body bends inwards, and forms hook portion, and the left and right sides of pulley assembly is clamping by hook portion.
Described hook portion external surface has the top bar to outer process.
Described hook portion comprises horizontal part and vertical portion, and the top bar is projected on the external surface of horizontal part
Under described cell wall external surface, upper two ends all have the convex tendon to outer process.
After adopting such scheme; the utility model is assemblied in the door and window fan material; pulley assembly is arranged in the protective sleeve body, has avoided like this pulley assembly to contact with the direct of door and window fan material, has solved pulley in use occurrence positions deviation and the frequent problem of damaging.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model preferred embodiment;
Fig. 2 is the floor map after the utility model preferred embodiment is installed.
The specific embodiment
By reference to the accompanying drawings, preferred embodiment is described in further details to the utility model.
A kind of aluminum alloy push-pull door and window trolley protective sleeve, critical piece are exactly the protective sleeve main body 1 that aluminium alloy extrusions is made.Protective sleeve main body 1 integral body is a trough body structure, comprises bottom land 11, two cell walls 12 and notch 13.
When pulley assembly 2 was installed down, the bottom land 11 of protective sleeve main body 1 was positioned at the top, has outside projection 14 on cell body 11, and the shape of the size and shape of projection 14 and pulley assembly 2 matches.Inside twice bending respectively of the end of two cell walls 12 forms toward interior hook portion 15.In cell body, the zone between projection 14, hook portion 15 has formed the cavity 3 that is used for installing pulley assembly 2.Hook portion 15 mainly comprises once the vertical portion 152 that forms after the horizontal part 151 that forms after bending and secondary bending, all has top bar 16 at the external surface of horizontal part 151, and top bar 16 is tight against in door and window fan material 3 inwalls on the section bar cell body 31 of inner process.
In addition, at the two ends up and down of two cell wall 12 external surfaces, has respectively a convex tendon 17 that is raised in cell wall 12 external surfaces.
When pulley assembly 2 was installed and used, the top of pulley assembly 2 snapped in to the inside of projection 14, and the vertical portion 152 of two hook portions 15 is resisted against respectively two sides of pulley assembly 2, carries out clamping.And horizontal part 151 external surfaces of hook portion 15 are resisted against in door and window fan material 3 inwalls to section bar cell body 31 upper surfaces of inner process, and top bar 16 is resisted against the medial surface of section bar cell body 31 simultaneously, stablizes screens.
Form certain cavity 4 between cell wall 12 inside and pulley assembly 2 in the utility model, can effectively avoid the wearing and tearing between pulley assembly 2 and protective sleeve body 1, have simultaneously the space of certain shockproof cushioning.In addition, in the present embodiment, cell wall 12 four outer convex tendons 16 prop up the inwall of door and window fan material 3, make like this cell wall 12 and door and window fan material 3 inwalls are also retained certain space 5, can prevent equally the wearing and tearing between cell wall 12 and door and window fan material 3, have simultaneously the shockproof cushioning effect.
Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
