Abstract
The utility model discloses an absorption type refrigerator door self -lock device installs on car as a house refrigerator door, include that directly block in the spring fixed slot on the sword iron from the sword iron, from locking piece, self -locking spring, another first joint is at the spring clamp slot rear portion from the locking piece, and a central part coiled circle, cover are on cylindrical protruding on the sword iron, and elasticity through the spring makes and can carry out the rotation of certain angle from the locking piece, and this auto -lock build portion has a bayonet socket, in can the draw -in groove of joint on the refrigerator, reaches and makes the fixed purpose of refrigerator lock. The utility model discloses an absorption type refrigerator door self -lock device simple structure, convenient to use can solve the problem of opening effectively under the inertial force that the refrigerator door produced in the car as a house motion process.
Description
Technical field
This utility model relates to a kind of self-locking device, particularly a kind of refrigerator doors self-locking device.
Background technology
Caravan refrigerator is a kind of refrigerator that can use on automobile, is with the equipment of the article such as cryopreservation food.In all kinds of refrigerators, absorption refrigerator is the high-tech product of a kind of environment-friendly type, owing to without freon, protecting atmospheric ozone layer, does not has compressor and any mechanical driving part, and operation will not produce any noise, is therefore relatively specific on caravan.
Traditional caravan refrigerator doors all uses the purpose that magnetic strip of paper used for sealing reaches to close door, but magnetic strip of paper used for sealing suction is limited, when automobile is kept in motion; under the effect of inertia force; the door of car refrigerator often automatically turns on, and causes the cold air in refrigerator to overflow, affects the preservation of food；When inertia force is big when, the opening speed of refrigerator doors and the amplitude of unlatching are relatively big, even refrigerator can be caused damage.
Utility model content
The purpose of this utility model is to overcome defect present in prior art, it is provided that a kind of absorption refrigerator self-locking device, and this device is arranged on refrigerator doors top, simple in construction, easy to operate, it is possible to make refrigerator doors reach the effect of self-locking, and convenient for unlocking after refrigerator doors is closed.
For achieving the above object, design of the present utility model is as follows:
A kind of absorption refrigerator door self-locking device, is applied in caravan refrigerator doors, including from bolt, self-locking block, self-locking spring；Wherein, having a cylindrical projections and a spring fixing groove on bolt, cylindrical projections is hollow structure, and inner surface is provided with screw thread；A bayonet socket, a circular hole, a plectrum and a spring card slot is included on self-locking block；Self-locking spring includes spring head and spring afterbody, and the center portion thereof is divided and is coiled into a circle shape；
During assembling, being enclosed within cylindrical projections by centre circle by self-locking spring, the spring head of self-locking spring is inserted in the spring fixing groove on bolt, and spring afterbody snaps in the spring card slot rear portion of self-locking block；Then, by self-locking block by circle hole sleeve thereon in the circular projection of bolt, then use inside screw precession cylindrical projections, more specifically, the screw terminal diameter of this screw is more than cylindrical projections external diameter, to reach purpose self-locking spring and self-locking block being fixed in cylindrical projections；The plectrum surface of self-locking block is vertical with self-locking block body surfaces, is used for stirring self-locking block, makes self-locking block rotate around cylindrical projections, bayonet socket is a breach concaved, make self-locking block head be formed one hook-shaped, can snap in the draw-in groove on refrigerator main body, reach the purpose of locking.
More preferably, this self-locking block head design is oblique angle structure, in can making the draw-in groove that self-locking block snaps on refrigerator main body when refrigerator doors is closed along hypotenuse voluntarily, and without stirring plectrum while closing refrigerator doors, reaches the effect of self-locking.
More specifically, the material used from bolt is ABS, the material that self-locking spring uses is spring steel, and the material that self-locking block uses is 1.2mm cold-reduced sheet.
Advantage of the present utility model and having the beneficial effects that: easily caravan refrigerator doors can be locked and unlocks, prevent refrigerator doors from automatically opening up in vehicle traveling process, and closing refrigerator door when, this device can lock automatically, and without more manual operation, convenient and swift.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
The technical scheme that this utility model is embodied as is:
Embodiment one (assembling example)
During assembling, being enclosed within cylindrical projections 3 by centre circle by self-locking spring 5, in the spring fixing groove 4 that the spring head 51 of self-locking spring is inserted on bolt, spring afterbody 52 snaps in spring card slot 24 rear portion of self-locking block 2；Then, self-locking block 2 is enclosed within the circular projection 3 of bolt 1 by circular hole 23 thereon, then uses screw precession cylindrical projections 3 internal, self-locking spring 5 and self-locking block 2 are fixed in the cylindrical projections 3 of bolt 1.
Embodiment two (making use-case)
The top being installed to car refrigerator door from bolt that will assemble, when refrigerator doors is in closedown lock-out state, clamping block 2 is connected in the draw-in groove in refrigerator body by bayonet socket 21, and refrigerator doors cannot automatically open up.
When refrigerator doors opened by needs, only need to be stirred in the counterclockwise direction by the plectrum 22 of clamping block 2, make clamping block 2 rotate around cylindrical projections 3, the head of this clamping block 2 just can produce in the draw-in groove from refrigerator body, thus reaching the purpose unlocked, the refrigerator doors that pulls outward just can be opened.
The when of closing refrigerator doors, the head of clamping block 2 can slide along hypotenuse under the active force closed the door, and in making the draw-in groove that the head of clamping block 2 slips in refrigerator body, reaches the effect of self-locking.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
