Abstract

The utility model discloses a non-clearance hinge of hardware and aims at technical problems that conventional like products have poor clearance sealing performance, and a door plank can only rotate around a fixed centre. The non-clearance hinge is formed by hinges, guide elements, a rivet, a short drive shaft and a long drive shaft, and the two hinges are respectively fixedly connected with a door frame and a door plank. The technical scheme includes that three through holes are arranged on each guide element, the rivet penetrating through the middle portion through holes of the guide elements connects the same into a four-bar transmission mechanism; the four-bar transmission mechanism is movably engaged with concave grooves inside the hinges via the short drive shaft and the long drive shaft; when the hinges are close, the four-bar transmission mechanism is arranged inside the concave grooves, and no clearance between the hinges; and when the hinges are opened, rotation centre of the four-bar transmission mechanism rotates along with rotation of rotation angle of the hinges. The non-clearance hinge resolves the technical problems, and has the advantages of simple structure, long service life, suitability of connecting and using with various door frames and door planks, and fine market prospect.

Description

No gap hinge

Technical field

The utility model relates to hardware, is a kind of no gap hinge.

Background technology

Present hinge means, or also claim hinge, it mainly is made up of fixed page or leaf sheet, moving page or leaf sheet and hinge axle center, the fixed page or leaf sheet that is installed on the doorframe is provided with the dead axle cover, and the moving page or leaf sheet that is installed on the door-plate is provided with the moving axis cover, and the hinge lock core passes dead axle cover and moving axis cover, hinge lock core and dead axle cover secure fit, cooperate with the moving axis cover is movable, moving page or leaf sheet rotates around the hinge lock core, makes door-plate along the doorframe folding.The shortcoming of said apparatus is that dead axle cover, moving axis cover and hinge lock core are located at outside fixed page or leaf sheet and the moving page or leaf sheet, and is therefore easily destroyed, and takes up room, blocks door-plate, makes door-plate diminish along the rotational angle of doorframe; There is the gap between doorframe and the door-plate, cleaning inconvenience; The hinge lock core is fixed in the dead axle cover, makes can only rotating along fixed center of door-plate, and rotational angle is restricted.

Summary of the invention

The utility model overcomes the deficiency of above-mentioned existence for addressing the above problem, and has designed a kind of no gap hinge, and the transmission mechanism of this hinge is built-in, does not have the gap between door-plate and the doorframe, and center of rotation is unfixing.The purpose of this utility model is achieved through the following technical solutions.

A kind of no gap hinge is made up of hinge page or leaf, guide, rivet, short pass axle and long pass axle, and a slice hinge page or leaf and doorframe are affixed, and another sheet hinge page or leaf and door-plate are affixed.

Described guide is provided with middle part through hole, long end through hole and short end through hole, and the middle part through hole that rivet passes guide connects into one four bar transmission mechanism with two guides.

Be provided with groove in the described hinge page or leaf, groove size and guide size match, the long end through hole that the short pass axle passes guide in the four bar transmission mechanisms will cooperate with the groove of hinge page or leaf is movable with the long approaching end of through hole of holding in the guide, and the short end through hole that the long pass axle passes guide in the four bar transmission mechanisms will cooperate with the groove of another sheet hinge page or leaf is movable with the short approaching end of through hole of holding in the guide.

Described hinge page or leaf is in and closes up state, four bar transmission mechanisms are built in the groove of hinge page or leaf, middle part through hole and the long upper surface of part body between the through hole of holding are concordant with the upper surface of hinge page or leaf on the guide, do not have the gap between two hinge pages or leaves, do not have the gap between the door-plate of two hinge page or leaf connections and the doorframe yet.

The guide middle part through hole that is connected by rivet on the described four bar transmission mechanisms is a center of rotation, and this center of rotation is fixing and rotate with the rotation of the rotational angle of hinge page or leaf.

The utility model efficiently solves transmission device and is exposed to the problem that thereby clearance seal poor-performing, center of rotation are fixed the restriction rotational angle between outer easily destroyed, doorframe and the door-plate, and simple in structure, easy assembling, application life are longer, the connection that is applicable to various doorframes, door-plate is supporting, and market prospects are good.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model and using method are further described.As Fig. 7, shown in Figure 8, two guides 2 are provided with middle part through hole 201, long end through hole 202 and short end through hole 203, and rivet passes middle part through hole 201 two guides 2 are formed one four bar transmission mechanism; Two hinge pages or leaves 1 connect doorframe and door-plate respectively, establish groove 101 in the hinge page or leaf 1, and short pass axle 4 passes long end through hole 202, and long pass axle 5 passes short end through hole 203, thereby with four bar transmission mechanisms and 101 movable cooperations of groove.Shown in Fig. 1～4, when two hinge pages or leaves 1 close up, the four bar transmission mechanisms that guide 2 constitutes are built in the hinge page or leaf 1, the upper surface of guide 2 is concordant with the upper surface of hinge page or leaf 1, do not have gap between the hinge page or leaf this moment, because two hinge pages or leaves connect doorframe and door-plate respectively, thus the gap do not had between the doorframe, door-plate yet, thus having prevented that dust and other impurities from entering makes cleaning inconvenient in the gap; In addition, four bar transmission mechanisms are built in the hinge page or leaf 1, make four bar transmission mechanisms be difficult for being damaged by foreign object.As Fig. 5, shown in Figure 6, when two hinge pages or leaves 1 are opened, the rivets 3 in the four bar transmission mechanisms middle parts through hole 201 become door-plate and with the center of rotation of the affixed hinge page or leaf 1 of door-plate, this center of rotation is fixing, rotates along with the rotation of hinge through angle.Thereby the door-plate rotational angle range is strengthened, and door-plate rotates freely.
