Abstract

The utility model discloses a kind of hinge fixation chip architecture, and through-hole is arranged in the middle part of the erecting bed, cricoid first heavy platform and the second heavy platform are extended downwardly out between erecting bed and through-hole；First layer connects erecting bed, and the first heavy platform lower end extends downwardly and shrinks to form the second heavy platform to through-hole, and the bottom end of second heavy platform and substrate bottom face are contour；It is equipped with to the horizontal-extending gasket ring of through-hole center position in the bottom end of the second heavy platform.When screw, which screws in door-plate, fixes door-plate and erecting bed, gasket ring becomes main stress surface, and the second heavy platform would not be deformed upon because of oppressing for screw, it is no longer necessary to control gap size, difficulty of processing and production cost are greatly reduced.

Description

A kind of hinge fixation chip architecture

Technical field

The utility model is related to a kind of component structurals for hinge more particularly to a kind of hinge to fix chip architecture.

Background technology

Hinge is usually mounted on furniture, to provide the buffering of door-plate opening and closing.It includes being fixed by screw and cabinet Mounting plate 100, on mounting plate 100 be equipped with screw in screw conical through-hole 110, structure is as shown in Figure 1, 2.When installation, The substrate 120 at 100 middle part of mounting plate is close to door-plate, and screw is then screwed at conical through-hole 110.Screw precession can squeeze after going The hole wall of conical through-hole 110 makes conical through-hole 110 that certain deformation occur downwards.In order not to allow 110 bottom of conical through-hole after deformation End resists door-plate, then the hollow mounting plate 100 where conical through-hole 110 is distorted by reaction force；Taper can be led to 110 bottom end of hole and the horizontal extension direction of substrate 120 form the gap 130 with certain distance, and gap 130 makes conical through-hole 110 have cushion space when sending deformation.But the size in gap 130 production when and bad control, Er Qiexuan Into different screws can it is identical walk journey under generate different pressure.It can be by 110 reverse extrusion of conical through-hole if gap 130 is too small And keep mounting plate 100 upwardly-deformed, it can be pushed by screw if gap 130 is excessive and pull mounting plate 100 and deform downwards.

Utility model content

The utility model aim, which is to provide in a kind of screw screwing operations, will not damage screw hole, and fixation more securely may be used The hinge leaned on fixes chip architecture.

A kind of hinge described in the utility model fixes chip architecture, includes the erecting bed of the left and right sides, two erecting bed lower ends It is interconnected by the substrate at middle part；Through-hole is set in the middle part of the erecting bed, is extended downwardly out between erecting bed and through-hole Cricoid first heavy platform and the second heavy platform；First layer connects erecting bed, and the first heavy platform lower end extends downwardly and shrinks shape to through-hole At the second heavy platform, the bottom end of second heavy platform and substrate bottom face are contour；It is equipped with into through-hole in the bottom end of the second heavy platform The horizontal-extending gasket ring in heart direction.

Second heavy platform makes the second heavy platform lower end and the lower face horizontal extension face position of substrate by the extension of the first heavy platform Maintain an equal level, in conjunction with the setting of gasket ring.Screw is set to screw in door-plate, when door-plate and erecting bed are fixed, gasket ring becomes main Stress surface will not act hole wall, will not lead to the deformation and damage of hole wall.Such second heavy platform would not be because of screw Oppress and deform upon that erecting bed is made to deform, do not have previous gap setting, difficulty of processing to substantially reduce, also reduce Production cost.And the inner space of screw hole increases than in the past, and head of screw does not protrude past on erecting bed, is further improved Aesthetic effect.

The first heavy platform upper end is rounded corner.Round and smooth angle can make screw when installing not fully vertical Head of screw will not be blocked, is made easier for installation.

It outwardly protrudes to form arc in the middle part of second heavy platform.Second heavy platform of arc makes screw hole inner space into one Step increases, and head of screw does not exert a force to the second heavy platform after screw screws in, i.e. the second heavy platform will not generate any deformation, stress surface again It fully falls on gasket ring.

The radian of first heavy platform is less than the radian of the second heavy platform.The first smaller heavy platform of radian is mainly used for spiral shell Ailhead imports in the second heavy platform, and the second larger heavy platform of radian is mainly used for more preferably storing head of screw.

Description of the drawings

Fig. 1 is the structural schematic diagram of hinge mounting plate in the prior art；

Fig. 2 be in Fig. 1 A-A to sectional view；

Fig. 3 is the schematic diagram that hinge described in the utility model fixes chip architecture.

Specific implementation mode

As shown in figure 3, it includes the hollow installation in the left and right sides that a kind of hinge described in the utility model, which fixes chip architecture, Platform 210, two erecting beds, 210 lower end are interconnected by substrate 220；Through-hole is arranged in 210 middle part of erecting bed, in erecting bed 230 and second heavy platform 240 of cricoid first heavy platform is extended downwardly out between through-hole, 230 upper end of the first heavy platform is to fall Fillet；Second heavy platform, 240 middle part outwardly protrudes to form arc；Second heavy platform, 240 bottom end and 220 bottom end of substrate The horizontal extension face sustained height in face；Second heavy platform, 240 bottom end is then equipped with to the horizontal-extending gasket ring in hole heart direction 250。

Second heavy platform 240 makes the bottom face at 240 bottom end end and substrate 220 of the second heavy platform by the extension of the first heavy platform 230 Horizontal extension face position maintains an equal level, in conjunction with the setting of gasket ring 250.Screw is set to screw in door-plate, door-plate and erecting bed 210 is fixed When, gasket ring 250 becomes main stress surface.Such second heavy platform 240 would not be deformed upon because of oppressing for screw from And erecting bed 210 is made to deform, do not have previous gap setting, difficulty of processing to substantially reduce, also reduces production cost.And spiral shell The inner space of nail hole increases than in the past, and head of screw does not protrude past on erecting bed 210, is further improved aesthetic effect.

For those skilled in the art, technical solution that can be as described above and design are made other each The corresponding change of kind and deformation, and all these changes and deformation should all belong to the guarantor of the utility model claims Within the scope of shield.
