Abstract

The utility model relates to a two-way open-and-close door device which is installed on a door, which is composed of a hinge seat with a hinge axis and a fixed seat which is provided with an occlusion groove, wherein the hinge seat and the fixed seat are respectively arranged on a door leaf or are installed at both sides of a main body provided with the door leaf. The utility model is characterized in that the hinge axis is a chamfered edge cylinder; the tail end of the occlusion groove is linked with a hinged hole of the hinge axis; the diameter of the hinged hole is larger than the groove width of the occlusion groove. The utility model with simple structure is arranged on a door and can cause the door to be opened and closed freely from both sides. The utility model is arranged on a refrigerator door which doesn't need to increase the size of the refrigerator door and can not increase the complex degree of a door body structure, thereby, the additional cost is reduced.

Description

The two-way switch door gear

The utility model relates to a kind of device that makes Men Nengcong both sides switch on the door that is loaded on.

Refrigerator doors or furniture door can seem practical and convenient by two-way switch.Existing make the technical scheme that door can two-way switch more, but its structure is all complicated.At present disclosed a kind of successful two-way switch door gear, its technical scheme is: set firmly hinge in main body (doorframe) both sides that door leaf is installed, on door leaf corresponding be provided with open at closing time can with the occlusal crib of hinge interlock freely and disengagement, and be provided with the snap fastener of being made up of connecting elements, spring and stop pin plate etc. on door leaf, hinge closes with the latch integrated circuit board after entering occlusal crib at closing time.The stop pin plate of this side and hinge break away from when a side is opened the door, and the stop pin plate of opposite side engages self-locking with hinge simultaneously.This two-way switch door gear can make the door random switch from both sides freely, and can prevent that door from coming off voluntarily.But snap fastener is complicated, and owing on door leaf snap fastener need be set, so refrigerator doors adopts this device can make the invalid size of a body and refrigerator increase, and makes the door body structure complexity, and increases cost.Simultaneously each switch door holder untie-sell plate and hinge all can collide and rub, prolonged and repeated switch door, and it is more serious to wear and tear.

The purpose of this utility model is to provide a kind of simple in structure, long service life, the two-way switch door gear that cost is low.

The utility model adopts following technical scheme for achieving the above object:

This two-way switch door gear, form by free bearing 1 that has hinge 2 and holder 3, the main body both sides that free bearing 1 and holder 3 are located at door leaf respectively or door leaf is installed, have on the holder 3 close when opening the door can with the occlusal crib 4 of hinge 2 interlocks or disengagement, the side of this occlusal crib 4 is the face of cylinder, and hinge 2 coaxial lines on the side of occlusal crib 4 and door right side on the holder 3 in a left side, the side of occlusal crib 4 and hinge 2 coaxial lines on the left of the door on the holder 3 on door right side.Hinge 2 is the chamfered edge cylinder, and the end of occlusal crib 4 is connected the hinge hole 5 that hinge 2 is arranged, and the diameter of hinge hole 5 is greater than the groove width of occlusal crib 4.

By such scheme as can be known, free bearing 1 and holder 3 are located at respectively on the main body both sides of door leaf or installation door leaf, hinged or disengagement can realize the two-way switch door by the interlock of hinge 2 on holder 3 and the free bearing 1.When door leaf closed, the hinge 2 of each chamfered edge all was positioned at the hinge hole 5 on each holder 3, and the reservation face of cylinder of hinge 2 is facing to the opening of occlusal crib 4.Need from this side application of force, the hinge 2 of this side to be thrown off with holder 3 along the occlusal crib 4 of holder 3 when open the door in the left side, the hinge 2 on the door right side rotates in the hinge hole 5 of holder 3 and the reservation face of cylinder of hinge 2 and the opening of occlusal crib 4 stagger simultaneously.So the time door right side hinge 2 can only in hinge hole 5, rotate and can't throw off with holder 3, thereby Men Buhui comes off when guaranteeing to open the door.Equally, it is also like this to open the door from the right side after door is shut again.

This two-way switch door gear is simple and reasonable for structure, with low cost, and use is reliable, convenient and the life-span is long, is particularly useful for the complexity that must not increase the size of refrigerator doors on the refrigerator doors, can not increase door body structure.

Further specify the utility model below in conjunction with drawings and Examples.

As Fig. 1～shown in Figure 4, the face of cylinder can be processed in two chamfered edge sides of hinge 2, and the occlusal crib 4 side coaxial lines of this face of cylinder and interlock mutually.The free bearing 1 of this two-way switch door gear and holder 3 can be located at door leaf respectively or install on the main body of door leaf.Fig. 1, free bearing 1 shown in Figure 2 are used to be located at the main body that door leaf is installed, if free bearing 1 is located on the door leaf, then can adopt Fig. 3, free bearing structure shown in Figure 4.Fig. 5, Fig. 6 have illustrated to be located at the structure of holder one embodiment on the main body that door leaf is installed.

Fig. 7, Fig. 8 have illustrated this two-way switch door gear to be located at two on the refrigerator doors example is set.As shown in Figure 7, as free bearing 1 is located on the door leaf 7, then holder 3 can be located on the main body 6 that door leaf is installed.As shown in Figure 8, as free bearing 1 being located on the main body 6 that door leaf is installed, then holder 3 can be located on the door leaf 7.For refrigerator doors,, also can directly on door leaf, inject the shape of occlusal crib 4 and hinge hole 5, to save holder if adopt the example that is provided with shown in Figure 8.This two-way switch door gear is used on the refrigerator doors outstanding apparent easy, practical.
