Abstract
The utility model relates to a sliding door device which comprises a pulley and a guide rail (2), wherein the pulley can be arranged on the guide rail (2) in a rolling manner. The sliding door device is characterized in that an annular groove (1) is radially sunken in the middle of the pulley, the radial section of the groove (1) is shaped as a triangle with an opening in the top surface, a rectangular dust filtering groove (11) which is provided with an opening in the upper part and can contain dust is arranged at the bottom corner of the radial section of the groove (1), when the pulley and the guide rail (2) are assembled together, the groove (1) of the pulley and a convex rail (7) of which the middle part is raised up to be adapted to the groove (1) can be assembled together in a rolling manner, and the pulley is connected with the sliding door through a pin roll (8) at the center. The sliding door device has the advantages that the dust filtering groove (11) arranged on the pulley can prevent dust from being accumulated between the pulley and the guide rail, the wearing resistance of the surface is increased due to a polytetrafluoroethylene coating, and the friction force is reduced.

Technical field
The utility model relates to a kind of moving door device, especially refers to for a kind of moving door device on the motor-car.
Background technology
Existing a kind of patent No. is that the Chinese utility model patent that the CN94242833.1 name is called " elastic sliding door " discloses a kind of moving door device, its structure includes: pin sleeve, the bearing pin stage clip is housed in the pin sleeve, bearing pin stage clip one side is equipped with bearing pin, and bearing pin is connected with pulley, has two locating slots on the bearing pin, the pin sleeve side links to each other with a dead axle cover, prop up to be equipped with in the dead axle cover and prop up a rationed marketing that fixes on the bearing pin locating slot, rationed marketing one side is equipped with props up a rationed marketing stage clip, and a rationed marketing is connected with stay cord.But its complex structure, and easily pile up dust between pulley and the guide rail and cause pulley to work, so its structure is further improved.
The utility model content
Technical problem to be solved in the utility model is that a kind of ingenious, simple in structure, easy for installation, long service life and a kind of moving door device that can dust stratification of designing is provided for above-mentioned prior art problem.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this moving door device, comprise pulley and guide rail, described pulley can rollably place on the guide rail, it is characterized in that: the middle part radial depressions of described pulley has the groove of annular, the radial section of described groove is the triangle of end face opening, the base angle of the radial section of described groove is the rectangle filter dirt groove of the accommodating dust of energy of top opening, when described pulley and set of rails are fitted together, the groove of described pulley and middle part raise up and form with the suitable protruding rail of groove and can rollably be set together, and described pulley is connected with sliding door by the bearing pin at center.
As improvement, described pulley comprises outer ring, inner ring, ball and retainer, and described ball can rollably place on the retainer, and can place actively between outer ring and the inner ring together in retainer.
As improvement, be provided with dust cap between described outer ring and the inner ring.
As improvement, be provided with side by side two row's balls between described outer ring and the inner ring.
As improvement, the external surface of described outer ring scribbles polytetrafluoroethylene floor, and the thickness of described polytetrafluoroethylene floor is preferably 0.03～0.08mm.
As improvement, the surface of described protruding rail scribbles polytetrafluorethylecoatings coatings, and the thickness of described polytetrafluorethylecoatings coatings is preferably 0.08～0.20mm.
Compared with prior art, the utility model adopts the middle part radial depressions of described pulley that the groove of annular is arranged, the radial section of described groove is the triangle of end face opening, the base angle of the radial section of described groove is the rectangle filter dirt groove of the accommodating dust of energy of top opening, when described pulley and set of rails are fitted together, the groove of described pulley and middle part raise up and form with the suitable protruding rail of groove and can rollably be set together, and described pulley is connected with sliding door by the bearing pin at center.Its advantage is: the filter dirt groove that arranges on the pulley can prevent that dust from piling up between pulley and guide rail; scribble the polytetrafluorethylecoatings coatings that abrasion resistance is good, frictional force is little on the contact surface of pulley and guide rail; can effectively protect pulley and guide rail, thereby improve the application life of device.
