The glass-frame riser slide block
Technical field
The utility model relates to a kind of auto parts, particularly a kind of glass-frame riser slide block.
Background technology
Glass-frame riser is the auto parts of using always, almost each automobile all needs glass-frame riser, in glass-frame riser, the riveting shaft assembly cooperates with the glass-frame riser slide block, the glass-frame riser slide block slides in guide rail, as falling the device main motion parts, the glass-frame riser slide block plays motion in the lifter motion process, position-limiting action, the effect of angle adjustment is provided in the glass lifting process simultaneously, and existing various glass-frame riser slide blocks adopt all closely that sphere cooperates, and it is big to have an inside and outside friction area of slide block, frictional resistance is big, simultaneously the slide block guide rail contact area is little, the excessive cracky of slide block pressurized, and easy loose spacious abnormal sound during operation.
Chinese patent publication number CN 201420461Y, open day 2010-03-10, a kind of automobile front door glass-frame riser slide block is disclosed, comprise guide portion, connecting portion and sliding part, described sliding part is a double-decker, is from outside to inside: the substrate of PA66 and with the contact site of slide rail sliding-contact.Though this patent can be apt to the resistance to impact of slide block, improve application life, this patent has still that the inside and outside friction area of slide block is big, frictional force is big, simultaneously slide block and glass-frame riser rail engaging structure instability, be easy to generate the shortcoming of breakage.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to use, has better flexibility, less frictional resistance, can turn to flexibly, in being installed, cooperation has than rock-steady structure, cracky not, use cooperates glass-frame riser slide block closely with the glass-frame riser guide rail.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of glass-frame riser slide block, comprise outer slide, described outer slide is provided with the spherical groove that has round mouth, described glass-frame riser slide block also includes inner slide, described inner slide is the billiard table shape, be fixedly connected with the little axle of slide block on described inner slide one end, described outer slide is set in the outside of inner slide, and the curvature of described spherical groove cambered surface is greater than the curvature of described inner slide cambered surface.The glass-frame riser slide block also includes inner slide, inner slide is the billiard table shape, be fixedly connected with the little axle of slide block on inner slide one end, the little axle of slide block cooperates with the riveting axle, in the glass-frame riser motion process, play motion, position-limiting action, the effect of angle adjustment is provided in the glass lifting process simultaneously, outer slide is set in the outside of inner slide, the curvature of spherical groove cambered surface is greater than the curvature of inner slide cambered surface, the curved surface that is provided with slide block in the prior art like this changes the contact of two end lines into whole contact of curved surface, guaranteed that inner slide had not both had the footpath, axial float can rotate again, simultaneously flexibly, but inner space oiling, to carry out the grease compensation, further reduce frictional resistance, increase application life.
As preferably, described outer slide is cube.Outer slide is cube can change original slide block and guide rail into the face contact by contacting, increase the contact area of slide block and guide rail, slide block is mean forced when work, has guaranteed the stationarity when slide block moves in guide rail, avoids bad phenomenon such as abnormal sound, shake to take place.
As preferably, all seamed edges of described outer slide are round-corner transition.All seamed edges of outer slide are round-corner transition when having guaranteed structural strength, have reduced the frictional resistance of slide block and guide rail.
As preferably, the little axle of described slide block cross section is " worker " font.The little axle of slide block cross section is " worker " font, can with play a part during the riveting axle cooperates fixingly, strengthened the intensity of structure.
As preferably, described outer slide round mouth is provided with the reinforcing rib of annular.Round mouth has been set the movement locus of the little axle of slide block, at the round mouth place, so because the collision in the motion is easy to breakage, so the outer slide round mouth is provided with the structural strength that the reinforcing rib of annular can reinforcing glass lifter slide block, improved stability.
As preferably, described outer slide has bottom outlet in the couple positioned opposite of round mouth.Outer slide has bottom outlet in the couple positioned opposite of round mouth, by the active orientation that bottom outlet can increase inner slide is set, increases to the form that radial-axial can move from single radial motion mode.
As preferably, described bottom outlet is rounded, and the diameter of described bottom outlet is greater than the diameter of described round mouth.Bottom outlet is rounded, and bottom diameter is provided with the scope of activities that can increase inner slide more widely like this greater than the diameter of round mouth, better plays the effect of angle adjustment in the glass lifting process.
The beneficial effects of the utility model are: the utility model has guaranteed that greater than the mode of the curvature of described inner slide cambered surface inner slide had not both had footpath, axial float by the curvature that the spherical groove cambered surface is set, can rotate flexibly again, simultaneously, but inner space oiling, to carry out the grease compensation, further reduce frictional resistance, increase application life.

The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
A kind of glass-frame riser slide block (referring to accompanying drawing 1), comprise outer slide 1 and inner slide 2, outer slide 1 is cube, all seamed edges of outer slide 1 all adopt round-corner transition, the inside of outer slide 1 is provided with spherical groove 6, the upper surface of outer slide 1 offers round mouth, and round mouth is communicated with spherical groove, and round mouth extends upward and forms reinforcing rib 4, the soffit of outer slide offers bottom outlet 5, bottom outlet 5 is rounded, and the diameter of bottom outlet 5 is greater than the diameter of round mouth, and inner slide 2 is billiard table shape, inner slide 2 is embedded in spherical groove 6, the cambered surface curvature of inner slide 2 is less than the cambered surface curvature of spherical groove 6, and the upper surface of inner slide 2 is connected with the little axle 3 of slide block, and the cross section of the little axle 3 of slide block is " worker " font.
Work in coordination with riveting axle and guide rail when the utility model uses, the little axle of slide block is fixed on the riveting axle, and outer slide and guide rail cooperatively interact, in the lifting process of glass, and little of riveting axle drive slide block, outer slide slides on guide rail, and inner slide rolls in spherical groove.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
