Abstract

The utility model relates to a structure on two lower sides of a bidirectional door. The lower opening of a groove opening is provided with a component 7 along an end face. The outer side position of the component is a guiding inclined face 8 towards a door body. The supporting face of the door body is positioned at the inner end position of the lower opening. The component 7 is in a convex table type, a rolling ball type, or a roller type. When the door is closed, the lower opening of the groove opening of the door body along the guiding inclined face on the end face firstly is contacted and connected into the outer edge of the hinging seat support lug of a box body so that the droopy door body is lifted along the inclined face. Thus the corresponding displacement of the lower end face of the groove opening of the door body, the groove body and a hinging shaft mechanism is eliminated, and the mutual collision of the lower end face of the groove opening of the door body, the groove body and a hinging shaft mechanism is avoided.

Description

The notch structure of both sides, bidirectional gate lower end

The utility model relates to the improvement of both sides, two-way every body lower end notch structure.

Bidirectional gate is used for can being opened by left and right sides either side behind the product.Figure 1 shows that when bidirectional gate is used for refrigerator the view when opening certain position by the left side, two-way every body upper and lower side both sides are respectively equipped with four notches 1, every notch is interconnected by end opening and inner edge mouth and constitutes, and the door body is that four hinged shaft mechanism, 2 realizations by opposite position on four notches on it and the casing are connected.The door body is when being opened by the left side as shown in Figure 1, and the hinged shaft mechanism of right side upper and lower side plays a part to support a body, and the hinge of left side upper and lower side then breaks away from notch, on the contrary when opening by the right side then.At closing time, the inner edge mouth edge of notch and end opening end will be through the outside lefts of hinged shaft mechanism along first-selection, the semicircle segmental arc position 3 until notch the inner, and it is to relatively rotate around hinge 4 in order to satisfy the door body that semicircle segmental arc 3 is set.Because the end opening position end door of present both sides, two-way every body lower end notch is plane structure, at closing time, because the Men Ticheng that opens is cantilever-shaped, cause the door body of opening a side sagging, cause the notch end opening end face of this side and notch and hinged shaft mechanism to produce relative dislocation, therefore, when the close hinged shaft mechanism of notch, the end face 5 at notch end opening place collides along 6 generations with the journal stirrup outer side edges in the hinged shaft mechanism, and a body can not successfully be closed.

The purpose of this utility model provides the notch structure of both sides, a kind of bidirectional gate lower end, and this notch structure can make its body successfully close.

Technical scheme is, at the end opening of both sides, two-way every body lower end notch 1 along end face setting and the corresponding member 7 of this end opening, the outside left of this member is provided with the guiding surface 8 towards the door body, face and guiding surface 8 that this member is positioned at the inner position of end opening of notch 1 join, supporting surface for the door body, 8 pairs of door bodies at closing time of guiding surface play the guiding role, and bidirectional gate can successfully be closed.

When the notch of lower end, two-way every body both sides adopts this notch structure, technique effect is obvious, when the door body of opening is closed, the end opening of door body notch at first contacts free bearing journal stirrup outer along the guiding surface of end face upper member 7, sagging door body is along lifting on the guiding surface, thereby eliminate the relative dislocation of the lower surface at door body notch place and notch and hinged shaft mechanism, avoid bumping mutually.

Its body was opened the view of certain position by the left side when Fig. 1 was used for refrigerator for existing bidirectional gate, Fig. 2 be the A of Fig. 1 to the structure enlarged drawing, be the topology view at position, two-way every body notch lower surface;

When implementing the utility model, the end opening that is located at notch 1 mainly contains three types structure along member 7 on the end face and that have guide function, narrates respectively below.

First type is that member 7 is projective table type member 7, and there is the guiding surface 8 towards the door body outside portion of this projective table type member, and the plane of projective table type member is a continuous level, and the part that is positioned at the inner position of end opening of notch 1 is the supporting surface of door body.Be specifically described with embodiment 1 to embodiment 3 below.

Embodiment 1.In this example, the end opening of both sides, two-way every body lower end notch is along the projective table type member 7 that tape guide inclined-plane 8 is set on the end face of a side, and its plane projection section extends to the week edge of end opening the inner, to satisfy the door body more firm supporting surface is arranged.Then be side guiding, the inner form of structure that supports.

Embodiment 2.This example at the end opening of both sides, two-way every body lower end notch along projective table type member 7 is set on the inside line end face, its plane projection section is inner all along symmetrical length half greater than the hinge girth that is mated that is connected in casing along end opening, makes the corresponding supporting surface of Men Tiyou.In this example, end opening is along not having boss structure on the end face of the outside.Owing to be provided with the notch of boss, the plane of its boss inboard be the supporting surface of door body, a body lower surface and be connected on the free bearing journal stirrup of casing at regular intervalsly between the plane, and therefore, the end opening end face of no boss structure can not bump with the free bearing journal stirrup.This example is both sides guiding, the inner form of structure that supports.

Embodiment 3.See Fig. 7, Fig. 8, in this example, at the end opening of both sides, two-way every body lower end notch along projective table type member 7 is set on the whole end face.

Embodiment 4.See Fig. 9, Figure 10.This routine member 7 is the ball-type member, belongs to second type.This member is located at the end opening of notch along on the end face at inner position, at least be provided with in this member two, and symmetry at the ball 9 at position, end opening both sides, provide three balls in the diagram, two symmetries are wherein arranged at position, end opening both sides, its outside ball surface is a guiding surface 8, and (end) face is a door body supporting surface down.

Embodiment 5.See Figure 11, Figure 12.This routine member 7 is the roller member, so-called the third type.This member is located at the end opening of notch along on the end face at inner position, at least be provided with in this member two, and symmetry at the roller 10 at position, end opening both sides, be provided with four rollers in the diagram, wherein have two symmetries at end opening along the position, both sides, its face of cylinder, outside is a guiding surface 8, and (end) face is a door body supporting surface down.
