Abstract

The utility model relates to a pulley device for a sliding door window. The utility model comprises an outer shell, an inner shell, a pulley pin shaft and a regulating threaded rod, wherein, the outer shell is fixedly connected with a door window frame; both sides of the inner shell are respectively provided with an inclined long pin hole; the pulley is connected with the inner shell into an assembly through the pin shaft which passes through a pin hole; the inner sides at both sides of the outer shell are respectively provided with a guide groove which is communicated with two open end faces of the outer shell and is overlapped in a cross mode with the pin hole; the shaft end of the pin shaft is embedded into the groove and can freely slide along the groove. The pulley of the pulley device is replaced without removing the glass or offloading the outer shell. The utility model is not only convenient to assemble and disassemble, but also can save material and reduce maintenance cost.

Description

Slide door or window is walked wheel apparatus

The utility model relates to the wheel apparatus of walking that a kind of slide door or window uses.

Existing slide door or window is walked wheel apparatus and is made up of housing and the travelling wheel that is contained in the housing.Housing comprises shell and inner casing, and travelling wheel is installed on by bearing pin in the pin hole of inside and outside shell-side face, and shell is fixed in the framework of slide door or window.After slide door or window uses a period of time, because causing door and window to slide, the wearing and tearing of its travelling wheel or distortion have some setbacks, just need to change at this moment travelling wheel.Because travelling wheel and inside and outside shell are loaded into non-disconnectable integral body, and shell is fixed in the door window frame, thereby also must earlier glass of door and window be unloaded after taking off door and window, can walk wheel apparatus taking-up replacing whole.Not only troublesome poeration, effort, and glass of door and window very easily damages.In addition, be travelling wheel though walk the consumable accessory of wheel apparatus, the whole wheel apparatus of walking be changed, cause unnecessary waste.

The purpose of this utility model provides a kind of slide door or window that can change travelling wheel easily and walks wheel apparatus.

The utility model is realized in the following way: this slide door or window is walked wheel apparatus and is comprised shell, inner casing, travelling wheel, bearing pin and adjusting screw(rod), and shell and door window frame are affixed.The inner casing both sides respectively are provided with the microscler pin-and-hole of an inclination, and travelling wheel connects into an assembly by bearing pin that passes pin-and-hole and inner casing.The medial surface of shell both sides respectively is provided with two direction recess that uncovered end face is communicated with shell, and the microscler pin-and-hole juxtaposition of direction recess and inner casing, the axle head of bearing pin embed in the groove and can be free to slide along groove.When needs are changed travelling wheel, unclamp adjusting screw(rod), the assembly of inner casing and travelling wheel is pulled out along shell direction recess direction, break away from direction recess fully until the bearing pin axle head, travelling wheel is separated with shell with inner casing, need not to unload lower casing and just can be changed.

The utility model has the advantages that: 1. simple in structure, mounting or dismounting convenience.When needs are changed the travelling wheel that has worn and torn, need not to remove glass, unload lower casing, only need take off door and window, unclamp adjusting screw(rod), just can change travelling wheel easily, the layman all can operate.2. need not to change shell during owing to the replacing travelling wheel, thereby saved material, reduce maintenance cost.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

With reference to accompanying drawing, this slide door or window is walked wheel apparatus and is made up of shell 1, inner casing 2, travelling wheel 3, bearing pin 4, adjusting screw(rod) 5.Shell 1 is provided with and is used for and the fixing screw 8 of doorframe and window frame.Inner casing 2 both sides respectively are provided with the microscler pin-and-hole of an inclination, and travelling wheel 3 connects into an assembly by the bearing pin 4 that passes pin-and-hole 6 with inner casing 2 and places in the shell 1, and adjusting screw(rod) 5 is connected with the Closed End of inside and outside shell.The two sides of shell 1 respectively are provided with the direction recess 7 of a long inclination, and this groove is communicated with two

uncovered end faces

9,10 of shell.Microscler pin-and-hole 6 juxtapositions of direction recess 7 and inner casing 2.The axle head of bearing pin 4 embeds in the direction recess 7, and the width W of direction recess 7 and height H greater than the axle head width A of bearing pin 4 and the height B in the axle head embedding groove, can be free to slide along groove 7 with the axle head that guarantees bearing pin 4 respectively.When needs are changed travelling wheel 3, unclamp adjusting screw(rod) 5, the inner casing 2 and the assembly of travelling wheel 3 are pulled out along shell direction recess 7 directions, break away from direction recess 7 fully until bearing pin 4 axle heads, travelling wheel 3 is separated with shell 1 together with inner casing 2.When packing new travelling wheel into, the travelling wheel 3 and the assembly of inner casing 2 are inserted in the shell 1, allow travelling wheel bearing pin 4 two axial ends embed in the direction recess 7 of shell both sides, import shell along groove direction.Then adjusting screw(rod) 5 is screwed in the inner casing 2 corresponding screws 11.By adjusting the screw-in length of adjusting screw(rod) 5, just can change the relative distance of shell 1 and inner casing 2 end faces, thereby change the position of bearing pin 4 on the microscler pin-and-hole 6 of inner casing, to reach required travelling wheel setting height(from bottom).
