Abstract
The utility model discloses a pulley for a door and a window, which comprises a supporting seat, a pulley and a pin shaft, wherein an intracavity is formed in the supporting seat and the pulley is installed in the intracavity of the supporting seat by the pin shaft and can surround the pin shaft to rotate. The utility model is characterized in that the top of the supporting seat is provided with longitudinal flanges positioned on both sides and a longitudinal projection positioned in the middle part, wherein the top of the longitudinal projection positioned in the middle part is provided with a longitudinal groove. The utility model is suitable for the novel door and the window which are provided with frames made of aluminium alloy section steel, the utility model can be fixed to the section steel of the frames of the door and the window and has convenient and fast installation, and the soft connection adopted can always ensure that the door, the window and the aluminium sections for the frames of the door and the window do not disengage.
Description
The utility model relates to a kind of door and window accessory, particularly relates to a kind of door and window trolley that is applicable to alumium alloy door and window.
In the prior art, traditional aluminium alloy door's window glidewheel comprises supporting seat, pulley and bearing pin, wherein, supporting seat inside has cavity, end face is plane and is provided with installing hole, pulley is installed in the cavity of supporting seat by bearing pin, can rotate around bearing pin, its defective is: the installed surface of (1) above-mentioned door and window trolley and doorframe and window frame section bar guide rail is that the end face of door and window trolley is plane, during installation, must fix by adjustment screw, and this connection belongs to rigid connection, collision during the switch door and window can make screw loosening, causes getting loose of door and window and doorframe and window frame aluminium extruded sections, uses very inconvenient.(2) the traditional door and window pulley adopts the sheet iron plate punch forming mostly, and this type of material not only gets rusty easily, and weight is big, is not easy to transportation.
The door and window trolley that the purpose of this utility model provides a kind of simple installation, is difficult for getting loose.
The purpose of this utility model is to realize by following technical measures: it comprises supporting seat, pulley and bearing pin, wherein, supporting seat inside has cavity, pulley is installed in the cavity of supporting seat by bearing pin, can rotate around bearing pin, it is characterized in that: have vertical flange that is positioned at both sides and the vertical projection that is positioned at the middle part at described supporting seat top, wherein, the vertical projection top that is positioned at the middle part also has the longitudinal concave groove.
The door/window frame aluminium alloy extrusions that Baltimore groove described in the utility model can make the utility model be applicable to have corresponding construction, the bulge-structure that has the band Baltimore groove that is complementary with described Baltimore groove on the guide rail of this type of doorframe and window frame section bar, both cooperate space that supplies tapping screw to install and fix of formation.
Supporting seat top described in the utility model is positioned at the plane of end face for highly equating of vertical flange of both sides, and they all are higher than the top of vertical projection at middle part, becomes the contact surface with guide rail during installation, to guarantee the uniformity of carrying.
Vertical projection on the supporting seat end face described in the utility model is positioned at the transverse center position of supporting seat.
The bottom land width of the Baltimore groove on the vertical projection described in the utility model is less than width of rebate, and the shape of cross section of Baltimore groove can have multiple variation, as the pointed triangle of bottom land, trapezoidal or circular triangle etc.
In order to improve the load situation of pulley, it is smooth and easy to guarantee to slide, and also can set up the quantity of pulley, that is: the quantity of described pulley can be more than one, and all pulleys are installed in the cavity of supporting seat by the bearing pin that is parallel to each other separately respectively.
The material of the supporting seat described in the utility model can be selected nylon match steel for use, and is made by the injection moulding one-shot forming, and during installation, this material can be convenient to the fixing of tapping screw.
The utility model compared with prior art has the following advantages: (1) is because the vertical projection and the Baltimore groove structure thereof at supporting seat of the present utility model top, make it applicable to door/window frame aluminium alloy extrusions with corresponding construction, and only needing a tapping screw can realize fixing with the doorframe and window frame section bar, simple installation is quick.(2) because the utility model can adopt tapping screw to install and fix, belong to soft connection, door and window and doorframe and window frame aluminium extruded sections are never got loose, guarantee safe and reliable.(3) if adopt nylon match steel, not only can prevent to get rusty as main material of the present utility model, also weight reduction greatly, and save metal consumption, reach energy-conservation effect.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of embodiment of the present utility model.
Fig. 2 is the A-A sectional drawing among Fig. 1.
Fig. 1 is embodiment of the present utility model, it comprises supporting seat 1, pulley 2 and bearing pin 3, wherein, the body profile of supporting seat 1 is cuboid, inside has the open cavity of a side, this open sides is as the bottom of supporting seat, the quantity of pulley 2 is 2, two pulleys all bearing pin by separately are installed in the cavity of supporting seat 1, can rotate around bearing pin, have two vertical projections 5 that are positioned at vertical flanges 4 of both sides and are positioned at the transverse center position at the top of supporting seat 1, wherein, vertical flange of both sides is rectangular shape, and their end face is the plane that highly equates, all is higher than the top of vertical projection 5, vertically the top of projection 5 has the longitudinal concave groove, the bottom land of this Baltimore groove is pointed, and its width is less than width of rebate, and cross section is a triangle.The supporting seat 1 in the present embodiment and the material of pulley 2 are all selected nylon match steel for use.
