Abstract

The utility model discloses the back hinge of a jib door, which is used for the installation of an automatic door and resolves the problems of the complex fabricating process and consequent high cost of the prior hinges with the function of automatic return. The utility model is mainly composed of a hinge seat, a hinge plate, an upper return part, a lower return part, a spring and an oppositely prized screw. The upper and the lower return parts are respectively provided with first and second inclined planes, which face each other, the lower return part is fixed on the hinge seat, the upper return part is fixed in the shaft hole of the hinge plate, one end of the oppositely prized screw is fixed on the seat hole of the hinge seat orderly and penetrates the seat hole of the hinge seat, the lower return part, the upper return part and the spring, one end of the spring resists the upper return part and the other end of the spring resists the other end of the oppositely prized screw. Since the fabricating process of the utility model is simple, the cost is low, compared with the conventional techniques, the utility model has higher operational reliability.

Description

Hinge behind the jib door

(1) technical field

The utility model relates to a kind of loose-leaf hinge.

(2) background technology

Loose-leaf hinge with revolving door is a lot of at present, need with the hinge with automatic recurrence function sometimes, but there is the manufacturing process complexity in this hinge of commonly using with automatic recurrence function, so cost is higher.

(3) summary of the invention

The utility model is in order to solve the at present used hinge with automatic recurrence function because of the manufacturing process complexity, makes the cost problem of higher; The technical scheme that is adopted is: mainly reached by hinge seat, flap, upward recurrence, recurrence down, spring and form prizing screw, last recurrence and following recurrence respectively are provided with corresponding first and second inclined-plane, first and second inclined-plane is provided with in opposite directions, hinge seat is fixed in following recurrence, last recurrence is fixed in the flap shaft hole, to sled screw one end be fixed in hinge seat seat hole and wore hinge seat seat hole successively, return down, go up return, spring, spring one end is against last recurrence, and the other end is against to the sled screw other end.

The roundlet glass holder is located at outside the spring, and this is in order to protect spring and to play beauty function.

The sled screw other end is provided with plain cushion, and the spring other end is against plain cushion.

Good effect of the present utility model has: because the utility model manufacturing process is simple, so cost is lower, and compares with located by prior art and to have higher functional reliability.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

(4) description of drawings

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model;

Fig. 2 be described in the utility modelly go up to return, recurrences down, flap shaft hole, spring, roundlet cup and to prizing the plane structure schematic diagram of screw.

(5) specific embodiment

Embodiment: referring to Fig. 1 and Fig. 2, hinge behind a kind of jib door, mainly by hinge seat 10, flap 20, last recurrence 30, under return 40, spring 50 reaches to be formed sled screw 60, last recurrence 30 and following recurrence 40 respectively are provided with corresponding first, two inclined-planes 31,41, first, two inclined-planes 31,41 are provided with in opposite directions, under return 40 and be fixed in hinge seat 10, last recurrence 30 is fixed in flap 20 shaft holes 21, sled screw 60 1 ends are fixed in 10 holes of hinge seat 11 and wore 10 holes 11 of hinge seat successively, under return 40, last recurrence 30, spring 50, spring 50 1 ends are against last recurrence 30, and the other end is against to sled screw 60 other ends; Roundlet cup 70 is sheathed on outside the spring 50, and this is in order to protect spring 50 and to play beauty function; Sled screw 60 other ends are provided with plain cushion 71, and spring 50 other ends are against plain cushion 71.

Course of action of the present utility model is: hinge seat 10 is fixed in doorframe, flap 20 is fixed in door-plate, at this moment, on, under return 30,40 first, two inclined-planes 31,41 closely contacts, when door is opened, door-plate drives flap 20 to inner rotary, go up like this and return 30 and then flap 20 shaft holes 21 rotations together, first inclined-plane 31 of last recurrence 30 slips away down and returns 40 second inclined-plane 41, if the up mobile extrusion spring 50 of last recurrence 30 after unclamping hand, returns 40 second inclined-plane 41 because of the very strong elastic force of spring 50 generations can make first inclined-plane 31 of recurrence 30 turn to down, reset, realized that door-plate returns automatically.
