Abstract
The utility model provides a guide pulley for a hanging sliding door buffer. The guide pulley for the hanging door buffer comprises a bearing which is composed of an outer ring, an inner ring and balls which are arranged between the outer ring and the inner ring. The guide pulley for the handing door buffer is characterized in that a stepped hole is arranged in the inner ring, a boss is arranged on one end which corresponds to the stepped hole and protrudes from the end surface of the bearing, a rivet penetrates through the inner ring and is connected with a fixed object, a big head end of the rivet is positioned in the stepped hole, and the diameter of the inner ring of the bearing is matched with the diameter of the rivet. The guide pulley for the hanging door buffer has the advantages of being simple in structure and low in production cost, and improving market competition. A plastic buffer layer is arranged outside the bearing, and the buffer layer not only plays a role of buffering, but also reduces working noise. A counter hole is arranged in the inner ring of the bearing, so that in the process of assembled, the rivet or the big head end of a fixed bolt is positioned in the counter hole and does not protrude from the end surface of the bearing, and therefore, beautiful appearance is guaranteed, a space is not occupied, and crushing or friction against other parts is avoided.
Description
Technical field
The utility model relates to a kind of accessory of Door suspension snubber, specifically the directive wheel used of a kind of Door suspension snubber.
Background technology
Make at present and use glass Door suspension and room sliding door very general, its primary structure is to hang by forward and backward two door leafs driving wheel of using, glide that push-and-pull opens and closes and gains the name on four tracks of door top and bottom.Door suspension generally is two fan door leafs, at every fan door leaf above and below assembling pulley, is assemblied in the aluminum alloy rail.
At present; generally all used snubber on the Door suspension, and at the shifting block of stirring snubber of the interior installation of getting on the right track of Door suspension, when promoting Door suspension and keep to the side; shifting block is stuck on the movable part of snubber; drive sliding door slowly mobile, until rest in the frame next door of door, because the cushioning effect of snubber; sliding door can not bumped near in the doorframe; not therefore avoid sending noise because of collision, or even the protection sliding door can be and damaged in collision, so quite be subjected to liking of customer.All need to use directive wheel in the existing snubber, utilize the directive wheel on the snubber to contact with doorframe, make the certain gap of maintenance between Door suspension and doorframe, avoid producing between Door suspension and doorframe friction.Yet existing directive wheel mostly is greatly rolling bearing, during installation, utilize bolt or rivet to be fixed and be installed on the snubber fixed head, therefore there is following deficiency: 1) rolling bearing is that metal material is made, noise is larger when it contacts with the doorframe guide rail and rolls along the guide rail inwall, and the doorframe guide rail that easily weares and teares.2) on the bearing inner race be through hole, when rivet or bolt and its installation, the stub end of rivet or bolt will be given prominence to the bearing face certain altitude, affects first attractive in appearancely, second take up room, easily with bump the impact assembling with miscellaneous part.
The utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, good looking appearance after the assembling, the Door suspension snubber directive wheel that set bolt or rivet do not take up room.
The utility model is realized with the following methods: a kind of Door suspension snubber directive wheel, it comprises bearing, described bearing is by outer ring, inner ring and be installed in above-mentioned ball between the two and consist of, it is characterized in that: be provided with shoulder hole in the described inner ring, an end relative with this shoulder hole is provided with the boss of outstanding bearing face, one rivet passes inner ring and is connected with fixture, and described rivet stub end is positioned at stepped hole, and the bearing inner race diameter matches with rivet diameter.
Described outer ring is coated with the plastic cement cushion coat.
Described plastic cement cushion coat outer rim is arc arch shape.
Described plastic cement cushion coat is that the soft plastic material is made.
Described bearing is deep groove ball bearing.
The beneficial effects of the utility model are: 1) simple in structure, cost of production is low, improves the market competitiveness.2) bearing is provided with the plastic cement cushion coat outward, this cushion coat had both played buffering can also reduce work time noise.3) bearing inner race is provided with counterbore, and the stub end of rivet or set bolt is positioned at this counterbore during assembling, makes its not outstanding bearing face, when guaranteeing good looking appearance, does not also take up room, and avoids bumping or rubbing with miscellaneous part.

Fig. 3 the utility model directive wheel and rivet assembling drawing.
Fig. 4 the utility model general assembly effect schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.A kind of Door suspension snubber directive wheel, it comprises bearing, described bearing is by outer ring 2, inner ring 3 and be installed in above-mentioned ball between the two and consist of, it is characterized in that: be provided with shoulder hole 4 in the described inner ring 3, an end relative with this shoulder hole 4 is provided with the boss 5 of outstanding bearing face, one rivet 6 passes inner ring and is connected with fixture, and described rivet 6 stub ends are positioned at stepped hole, and the bearing inner race diameter matches with rivet diameter.
Described outer ring 2 is coated with plastic cement cushion coat 1.
Described plastic cement cushion coat 1 outer rim is arc arch shape.
Described plastic cement cushion coat 1 is made for the soft plastic material.
Described bearing is deep groove ball bearing.
During assembling: rivet 6 or set bolt are passed the inner ring of bearing, wherein require both to match by diameter, prevent from occurring between the two radially rocking.The stub end of described set bolt or rivet 6 is positioned at the counterbore of this bearing, make its not outstanding bearing face, when guaranteeing good looking appearance, also do not take up room, avoid bumping or rubbing with miscellaneous part, simultaneously the stub end of rivet or set bolt with can also prevent dust after shoulder hole cooperates, foreign material etc. enter in the bearing, the assurance bearing operation smoothly.Boss 5 on its middle (center) bearing is after assembling, and separate with fixed head the outer ring that bearing is rotated, and reserves enough free gaps, is conducive to the directive wheel normal operation.
Claims (5)
