Abstract
A flat head for hinge comprises a flat head body consisting of a flat head cover and a plunger, wherein an integrated boss is formed on the mounting end face on the side of the flat head cover facing the plunger. The integrated boss on the flat head cover is used as the solder point. After the flat head is mounted in a mounting hole of a hinge, the flat head is connected with an electric welding machine and is electrified, and the boss can be melted to combine with the end face of the mounting hole, thereby achieving welding. Compared with the prior art, the flat head has low requirement for processing accuracy but good fixation effect. When in use, the flat head can bear larger loads and can prevent failures due to the deformation of the mounting hole, thereby prolonging the service life. In addition, the process is simplified by obviating the design of the longer plunger of the flat head and knurling on the surface of the plunger.
Description
Technical field
The utility model relates to a kind of hinge, especially a kind of hinge tack.
Background technology
Hinge is a kind of common furniture five metals hinge arrangement, it generally is hinged by two fan leafs and forms, wherein the hinged end of two fan leafs is the installing hole that cooperatively interacts, in installing hole, penetrate rotating shaft, just two fan leafs can be combined, block by the installing hole of two tack more afterwards, just make two fan leafs be combined as complete hinge structure both sides.Hinge in the market, its tack is made up of tack lid and stick harness, pack into the stick harness part of installing hole of tack is an interference fit with installing hole, be to fix by extruding force between the stick harness of tack and the installing hole, general implementation method is, stick harness at tack partly carries out annular knurl, forms the annular knurl line, and it is fixing tack to be squeezed in the installing hole with its interference fit encapsulation afterwards again.The hinge of this structure in use, load forces can allow installing hole be out of shape gradually, the tack that is mounted thereon just may become flexible because of distortion, even causes and come off, thereby influences the application life of hinge; In addition, because the craft precision that cooperates of tack and installing hole requires than higher, and be to reach the effect that fixedly secures, the stick harness of tack partly need design longly increasing the contact area with installing hole, and needs annular knurl in the above, makes complex process.
Summary of the invention
At the problems referred to above, the utility model provides a kind of effect of fixedly securing that has, and the low hinge tack of technological requirement.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of hinge tack comprises the tack body of being made up of tack lid and stick harness, and described tack lid is provided with integrated salient point towards the installation end face of stick harness one side.
The beneficial effects of the utility model are: tack covers integrated salient point and uses as solder joint, after tack is contained in the installing hole of fan leaf, connect tack and energising with electric welding machine, then salient point just can melt and combine with the end face of installing hole, thereby reached the effect of welding, compare original product, requirement on machining accuracy of the present utility model is lower, but more firm fixed effect is arranged, not only can bear bigger load in use, and can not lose efficacy because of the distortion of installing hole, has longer application life, and the stick harness of tack does not need to design longlyer, and does not need annular knurl from the teeth outwards, has simplified processing technology.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a user mode schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of hinge tack provided by the utility model comprises the tack body of being made up of tack lid 11 and stick harness 12, and wherein, the tack lid 11 installation end faces towards stick harness 12 1 sides are provided with integrated salient point 13.
As preferred implementation of the present utility model, described salient point 13 is evenly distributed in the installation end face of tack lid 12, and it is stressed reasonable to make like this, is not easy to lose efficacy.
With reference to Fig. 2, when tack is installed on the installing hole 2 of fan leaf, stick harness 12 will put in the installing hole 2, and the installation end face of tack lid 11 then combines with the outer face of installing hole 2, and salient point 13 is just between the outer face of the installation end face of tack lid 11 and installing hole 2, in the assembling process of hinge, connect tack and energising by electric welding machine, because the characteristic of metal, salient point 13 can combine because of high temperature melt and with the end face of installing hole 2, after cooling, tack lid 11 just can tighten together with installing hole 2.
Tack provided by the utility model is compared original product, requirement on machining accuracy is lower, but more firm fixed effect is arranged, after tested, compare original structure, the utility model can bear 5 times pulling force in use, and it can not lose efficacy because of the distortion of fan leaf installing hole 2, has longer application life, and, the stick harness 12 of tack does not need to design longlyer, and does not need annular knurl from the teeth outwards, has simplified processing technology.
Claims (2)
