Technical field
The utility model relates to appliance field, is specifically related to a kind of door of refrigerator that is used for and returns self-locking device automatically and be provided with the refrigerator that this returns self-locking device automatically.
Background technology
At present, door of refrigerator body and electric refrigerator housing body adopt the free folding of hinge links mostly, gasket by being provided with magnet on the door body is to realize the complete closure of door body then, but in use but there are the following problems: 1, if the user is firmly too small at closing time, the door body does not close, even small gap, magnet gasket also can't allow a body closed fully.2, because the magnetic force of magnet gasket is limited, and along with the growth of service time, magnetic force also can slowly weaken, the suction-combining force also dies down thereupon, can not make a body airtight fully.3, exert oneself when closing the door when excessive, refrigerator door with the casing collision process in, can cause door not closed tight because bounce is excessive flicking.More than three problems all can cause the loss of cold air in the refrigerator, the waste of resource.
The utility model content
The utility model provides a kind of door of refrigerator to return self-locking device automatically, and this installs simplicity of design, and processing technology is easy, and production cost is low, and control refrigerator door switch is flexible.
The utility model further provides a kind of refrigerator that is provided with above-mentioned automatic recurrence self-locking device, this refrigerator returns self-locking device automatically owing to be provided with above-mentioned door of refrigerator, can not run off because of the refrigerator door closure does not tightly cause cold, thus the purpose that reaches energy savings, cuts down the consumption of energy.
For realizing goal of the invention of the present utility model, adopted following technical proposals:
A kind of door of refrigerator returns self-locking device automatically, the Men Tiyu chest hinge connects, its design feature is: fixing one by a bearing pin on the hinge of Men Tiyu casing top setting can be around the arc pull bar of bearing pin rotation, the arc pull bar limits its rotational angle by a limited block that is arranged on the hinge, one end of described arc pull bar links to each other with the spring that is in extended state all the time on being fixed on hinge, the other end of described pull bar is the recess of being with transition arc, described door body is provided with a cam, and the recess on described cam and the arc pull bar forms when the door body is closed and fastens.
Design feature of the present utility model also is: the hinge that is connected a body is provided with the through hole that passes for wire harness, realizes the data information exchange of electronic installation between casing and door body.
Another purpose of the present utility model is a kind of refrigerator of protection, comprises casing and door body, and by hinge links, its design feature is that described door body is provided with aforesaid automatic recurrence self-locking device between described casing and the door body.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the door of refrigerator of the utility model setting returns self-locking device automatically, when closing body, as long as after being closed into certain angle, the arc-shaped notch of the slyness of arc pull bar just can block the cam on the body, under the pulling force effect of spring, the arc pull bar rotates around bearing pin, and arc-shaped notch tightly blocks cam to realize the auto-lock function of opposite house body, guarantee the tight closure of door body, make it have higher functional reliability.Simultaneously in door body opening procedure, because separating of recess and cam makes to possess good hand feeling when opening the door.
2, the utility model is provided with the through hole that passes for wire harness on the hinge that connects the door body, realizes the data information exchange of electronic installation between casing and door body.
Description of drawings
Fig. 1 returns the structural representation of self-locking device automatically for the utility model.
When being in closed condition for the utility model door of refrigerator, Fig. 2 returns the self-locking device schematic diagram automatically.
Fig. 3 is that the utility model door of refrigerator arc pull bar and cam are thrown off back recurrence self-locking device schematic diagram automatically.
Fig. 4 returns the self-locking device schematic diagram automatically when being the self-locking of the utility model door of refrigerator arc pull bar pulling cam.
Number in the figure: 1, casing, 2, the door body, 3, hinge, 4, bearing pin, 5, the arc pull bar, 51 recesses 6, spring, 7 cams, 8, bolt, 9, screw, 10, through hole, 11 wire harness, 12 limited blocks.
The specific embodiment:
As shown in Figure 1, door of refrigerator returns self-locking device automatically, door body 2 is connected with casing 1 hinge, hinge 3 is fixed on the casing 1 by bolt 8, fixing one on the hinge of door body 2 and the setting of casing 1 top can be around the arc pull bar 5 of bearing pin 4 rotations, the arc pull bar limits its rotational angle by a limited block 12 that is arranged on the hinge, one end of arc pull bar 5 links to each other with the spring that is in extended state all the time 6 on being fixed on hinge, its other end is the arc-shaped notch 51 of a slyness, door body 2 is provided with a cam 7, cam 7 is fixed on the body 2 by screw 9, and the recess 51 on cam 7 and the arc pull bar forms when the door body is closed and fastens.In order to realize the circuit interface channel between casing 2 and the door body 1, on the hinge of door body, also be provided with the through hole 10 that passes for wire harness 11.
As shown in Figure 2, when refrigerator door 2 during in closure, arc pull bar 5 can freely rotate around bearing pin 4, under the pulling force effect of spring 6, arc pull bar 5 makes a door body 2 can be close to casing 1 by be strained and fixed cam 7 on door body 2 of recess 51, avoid the loss of cold in the refrigerator, in the certain angle when opening the door,, also possesses good hand feeling during refrigerator open simultaneously owing to be subjected to the pulling force effect of spring 6.
