Abstract
The utility model discloses a hinge which comprises at least two shaft sleeves (1) and a rotating shaft (2), wherein one shaft sleeve (1) is fixed with a component A (6), the other shaft sleeve (1) is fixed with a component B (7), the rotating shaft (2) is sleeved in a shaft hole of the shaft sleeve (1), and a first notch (4) penetrating through the wall of the shaft sleeve (1) through the shaft hole is arranged at one end of each shaft sleeve (1); a second notch (5) penetrating through the wall of the shaft sleeve (1) through the shaft hole is arranged at the other end of each shaft sleeve (1), the first notch (4) is opposite to the second notch (5) in the radial direction of the shaft sleeve (1), the width of the first notch (4) and the second notch (5) is not smaller than the bore diameter of the shaft hole, and the total length of one first notch (4) and one second notch (5) is equal to the length of one shaft sleeve (1). The hinge is convenient to form by mold pressing and has high yield.
Description
Technical field
The utility model relates to a kind of hinge, especially a kind of hinge of compression molding.
Background technique
The hinge of traditional compression molding (as the hinge of glass fibre reinforced plastic material) comprises at least two axle sleeves and a rotating shaft, and axle sleeve and A parts are fixed, and another axle sleeve and B parts are fixed, and rotating shaft is linked in the axis hole of above-mentioned axle sleeve.
There is following defective in the hinge of above prior art: during the axle sleeve of this hinge of compression molding, because the axis hole at axle sleeve center exists, must in mould, install and fix core rod, after the compression molding, must loose core again, and the process complexity that core rod is installed in mould, and the process of assembling core rod makes mistakes easily, causes the product rejection rate height; Equally, the process of loosing core after the compression molding also bothers, and damages product easily.
The model utility content
The technical problems to be solved in the utility model is that a kind of hinge that compression molding is convenient, yield rate is high is provided.
Technical solution of the present utility model is, a kind of hinge with following structure is provided, it comprises at least two axle sleeves and a rotating shaft, axle sleeve and A parts are fixed, another axle sleeve and B parts are fixed, rotating shaft is linked in the axis hole of above-mentioned axle sleeve, and an end of each axle sleeve is provided with one first breach that connects the axle sleeve wall from axis hole; The other end of each axle sleeve is provided with one second breach that connects the axle sleeve wall from axis hole, first breach and second breach in the radial direction of axle sleeve towards opposite, the width of first breach and second breach all is not less than the aperture of axis hole, and the total length of one first breach and one second breach equals the length of an axle sleeve.
After adopting above structure, a kind of hinge of the utility model compared with prior art has the following advantages:
Because an end of each axle sleeve is provided with one first breach that connects the axle sleeve wall from axis hole; The other end of each axle sleeve is provided with one second breach that connects the axle sleeve wall from axis hole, first breach and second breach in the radial direction of axle sleeve towards opposite, the width of first breach and second breach all is not less than the aperture of axis hole, the total length of one first breach and one second breach equals the length of an axle sleeve, like this, on upper die tooling, establish a downward projection, the axis hole of this projection and first breach and axle sleeve one end coincide, simultaneously, establish a projection that makes progress on bed die, the axis hole of this projection and second breach and the axle sleeve the other end coincide; When fit on, bed die, only the projection of the projection of upper die tooling and bed die alternately need be pegged graft gets final product; And after mold pressing finishes, along vertically just the demoulding going out this axle sleeve to separating upper and lower mould, this mould needn't install and fix core rod, just having stopped the assembling core rod makes mistakes and causes the drawback of product rejection, also having stopped naturally to loose core to slip up causes the drawback of product rejection, so the assembling of the mould of this hinge is simple, compression molding is convenient, yield rate is high; And first breach and second breach are alternately distributed, and make rotating shaft still by the axle sleeve fit, can not influence the normal use of hinge.
As improvement, the width of first breach and second breach is equal to the aperture of axis hole, and like this, the simple in structure and demoulding of mould is smooth.
As improving, axle sleeve is three again, and axle sleeve and A parts in the middle of being positioned at are fixed, and two axle sleeves that are positioned at two ends are all fixed such simple and stable structure with the B parts.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model hinge, it comprises three axle sleeves 1 and a rotating shaft 2, rotating shaft 2 is linked in the axis hole 3 of above-mentioned three axle sleeves 1.Axle sleeve 1 in the middle of being positioned at is fixed with the A parts, and two axle sleeves 1 that are positioned at two ends are fixed with the B parts.One end of each axle sleeve 1 is provided with one first breach 4 that connects axle sleeves 1 wall from axis hole 3, and in other words, first breach 4 extends radially outwardly and the outlet of first breach 4 is positioned at the outer peripheral surface of axle sleeve 1 from axis hole 3.The other end of each axle sleeve 1 is provided with one second breach 5 that connects axle sleeves 1 wall from axis hole 3, and in other words, second breach 5 extends radially outwardly and the outlet of second breach 5 is positioned at the outer peripheral surface of axle sleeve 1 from axis hole 3.Towards opposite, the width of first breach 4 and second breach 5 is equal to the aperture of axis hole 3 in the radial direction of axle sleeve 1 for first breach 4 and second breach 5, and the total length of one first breach 4 and one second breach 5 equals the length of an axle sleeve 1.
