Description

Can left and right open door hinge

Technical field

The utility model relates to a kind of hardware, relates to the door hinge of bidirectional opening about a kind of to make specifically.

Background technology

The door that household electrical appliance (as refrigerator, micro-wave oven) or finished product cabinet adopt one direction to open usually, can use inconvenience, even cannot use in the restricted situation of riding position.For addressing this problem the door also having and adopt and can change opening direction, but needing to carry out extra disassemble and assemble work, having any problem the people weak for manipulative ability or the elderly.Need not install in addition just can directly left and right both direction open door, it is the technical scheme of the patent document disclosed " the two refrigerator doors opened in a kind of left and right " of CN202393147U as the publication number door of left and right two-way switch " a kind of can " and publication number disclosed in the patent document of CN201730452U, but these technical schemes increase its function of component affecting and outward appearance because of needs on door body, and can not make standard member.

Summary of the invention

The purpose of this utility model is the above-mentioned deficiency that will solve prior art, provides the door hinge of two-way direct unlatching about a kind of to make, solid and reliable and highly versatile.

The technical solution of the utility model is: hold each installation rotating shaft in the left and right on the both sides up and down of door, a hinge bodies is respectively installed in position corresponding with the rotating shaft of door on doorframe.The structure of hinge bodies on one piece of substrate, drives a gathering sill to hold the rotating shaft of door, a rotating grab installed by substrate, rotating shaft location can stop it movable along gathering sill at closure state by grab, grab between two hinges in left and right connects realization interlocking by a connector, below rotating shaft when having a spring leaf to be positioned at door closure state in gathering sill, when rotating shaft is left, spring leaf is upspring and is blocked grab and hold it in open position.

The duty of hinge is described below:

1. when the door closes, rotating shaft is in the inner end of gathering sill, and rotating shaft is blocked in the outer end of grab, and the spring on connector applies power to grab makes rotating shaft locate, and door is stable closes, and spring leaf is departed from by rotating shaft pressure and grab.

2. when the side of door is stressed overcome the spring power be applied on grab be pulled outwardly time, the grab of this side is backed down by the rotating shaft of door, connector moves thereupon, middle spring is compacted and foreshorten to most short status, grab on opposite side hinge is held out against and makes it stiff, door just with the rotating shaft of opposite side for axis rotation and opening, when the rotating shaft of the side that is opened goes to the outermost end of grab, the spring leaf being positioned at gathering sill is upspring grab to block and is made it to keep this state after the door is opened, and the grab of opposite side continues the rotating shaft of this side to clamp because of the effect of connector.

3., when the door that is unlocked is closed, rotating shaft enters gathering sill, and spring leaf is pressed down by rotating shaft and departs from grab, and grab is promoted by rotating shaft and rotates, until rotating shaft reach fastening position after grab block outside rotating shaft, door is in closed condition.

4., when the both sides of door are subject to outside power simultaneously, two, left and right grab connected piece withstands and can not forward the angle that rotating shaft is departed to, and door can not be opened.

A kind of form of connector is two connecting rods, and intermediate stretchable also has spring; The another kind of form of connector is the wire rope that centre is attached with spring.According to the difference of connector form, also different from the position that grab connects.

Even part or wire rope can be arranged in doorframe or hide with ornamental strip.

The beneficial effects of the utility model are: Men Kecong the right and left arbitrarily pulls open and can prevent from coming off; Thus the function of opposite house body and outward appearance do not affect door only to increase by two rotating shafts; The function of hinge does not affect by door is high, and the length that only need adjust connector just can adapt to different gate-widths, highly versatile.

In figure, 1. substrate, 2 gathering sills, 3. spring leaf, 4. grab, 5. connecting rod, 6. spring, 7. rotating shaft, 8. grab axle, 9. wire rope.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described.

Fig. 1 is the structural representation of first embodiment of the present utility model, adopts connecting rod as connector.Illustrated is state when closing, represents clearer, not shown rotating shaft 7 for making main member.In figure, grab 4 is installed on substrate 1 by grab axle 8, and 5, connecting rod is attached on grab 4, and spring leaf 6 is depressed, and its free end is positioned at below grab 4.

Be installed on four hinges on doorframe up and down, left and right is symmetrical mutually.

When door is closed, the state of hinge is with reference to Fig. 2, and the direction of motion that gathering sill 2 limits rotating shaft 7 makes it to seesaw, and rotating shaft 7 is blocked by the outer end of grab 4, and spring 6 provides pressure that rotating shaft 7 is located by connecting rod 5 to grab 4.

When door is opened, the state of hinge is with reference to Fig. 3.Under the effect of external force, rotating shaft 7 is outwards moved along gathering sill 2 and is headed on grab 4 and rotates around grab axle 8, and when shown position, grab 4 turns to maximum angle, rotating shaft 7 departs from its constraint, door is opened, and spring leaf 3 is upspring simultaneously, and the free end of its L shape blocks grab 4 makes it fixing.Connecting rod 5 moves along with the rotation of grab 4, and spring 6 is compressed, and the grab 4 on the hinge of opposite side holds out against and the rotating shaft 7 of this side can only be rotated and can not move along gathering sill 2 by connecting rod 5.

When door is contrary to the above by its process when being opened to closedown, rotating shaft 7 enters gathering sill 2, is depressed by spring leaf 3, and grab 4 can rotate along with rotating shaft 7, and is located when rotating shaft 7 arrives fastening position.

Time stressed when the both sides of door while, the rotating shaft 7 on both sides promotes grab 4 simultaneously, but can not forward owing to being withstood by connecting rod 5 position that rotating shaft 7 is departed to, and door can not be opened.

Connector in the utility model also can adopt wire rope, with reference to the embodiment of second shown in Fig. 4.In Fig. 4, wire rope 9 is fixedly connected on grab 4, and its length can make the grab 4 of side turn to when rotating shaft 7 can depart from just to strain, the same with connecting rod 5 like this, can ensure that the grab 4 of opposite side can block rotating shaft 7 and not move.Lax wire rope 9 is strained and is provided power rotating shaft 7 compressed to grab 4 by spring 6 when the door closes.

Connecting rod 5 or wire rope 9 can be arranged in doorframe in actual use, or hide with ornamental strip outside and do not expose.
