Hinge is a kind of structure that is used to connect between door and the doorframe, existing a kind of aluminum metal door, its hinge is for to make with door is one-body molded, wherein the structure of hinge is as follows: comprise the pivot that can directly fixedly connected with doorframe, with a door connector of fixedlying connected with door, the door connector has a round end that can rotate around pivot, after installing, because the door connector can rotate around pivot by round end, so can and then realize the opening and closing of door.This hinge of the prior art, has following defective: because the door connector is a movable part, in the process of door open and close, the round end of door connector can rotate around pivot, in the process of rotation, can produce friction to the fitting face between pivot and the round end, thereby taking place, wearing and tearing make its fit clearance increase, after this wearing and tearing increased to a certain degree, pivot will break away from from round end; Simultaneously in this existing hinge structure, the angular dimension that door is opened is to determine by the radian of the round end port in the door connector is big or small, so realize normally opening of door, the shared radian of its round end port can not be provided with too smallly, can only be to be slightly less than 90 degree, will from round end, come off so so just make pivot slightly wear and tear, make reduce greatly the application life of hinge.

Summary of the invention

At above-mentioned deficiency in the prior art, even the utility model provides after the wearing and tearing of a kind of pivot also difficult drop-off, load-bearing property is better, application life big leap ahead hinge.

The technical solution of the utility model is:

A kind of hinge structure, its characteristics are, comprise a door connector, a pivot, a frame connector, described door connector has a round end that can rotate around pivot with a link that is connected mutually and, described pivot is positioned in the middle of the connector round end and with the frame connector and is connected, described frame connector has at least one fixed end and restriction that is used for fixedlying connected with doorframe and holds, the radian of wherein said door connector round end is greater than the radian of the gap segments of described frame connector restriction end, the meaning promptly refers to, the radian of round end and frame connector restriction end self radian sum are greater than 360 degree, like this can so that when the door connector when pivot rotates, round end can only be limited in rotating in the restriction end of described frame connector and the space between the pivot, even after so both can having made that pivot was subjected to fretting wear, can in the round end of door connector, not come off yet.

As the further optimization of the technical program, the restriction end on the described frame connector is the camber setting around pivot, and it is stressed to reduce spin friction like this, reduces wearing and tearing, can save material simultaneously.

The beneficial effect of the technical program is:

Limit at the round end that is provided with on the frame connector on the restriction end opposite house connector in the utility model, even so both can make between round end and the pivot after the fretting wear, pivot can not come off yet, thereby has strengthened the load-bearing property of hinge greatly, has increased the application life of hinge.

Description of drawings

Fig. 1 is a cross section structure schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details:

As shown in Figure 1, a kind of hinge structure, its characteristics are, comprise a door connector 1, a pivot 2, a frame connector 3, described door connector 1 has the round end 5 that a link 4 that is connected mutually with door and can rotate around pivot 2, described pivot 2 is positioned in the middle of a connector 1 round end 5 and with frame connector 3 and is connected, described frame connector 3 has a fixed end 6 and a restriction that is used for fixedlying connected with doorframe and holds 7, and the radian of wherein said door connector 1 round end 5 is greater than the radian of described frame connector 3 restriction ends 7 gap segments.

In this specific embodiment, the restriction end 7 on the described frame connector 3 is the camber setting around pivot 2, is provided with screw hole 8 with the fixed end on the time-frame connector 36, is used to be fixed in doorframe.

During concrete enforcement, the door connector in this hinge structure can adopt aluminium one-body molded with door, and frame connector and pivot adopt the aluminium moulding separately, and then frame connector and pivot can be realized cooperating in the termination point casing of door connector is packed it into.Only the frame connector need be fixed on the doorframe of installation place during installation and get final product.The utility model is specially adapted to be arranged on various aluminium alloy doors or the aluminum window and uses.Certainly the utility model also can also be to make an independent hinge structure, only need connect end during use and be fixedly connected on the door, and fixed end is fixed on the doorframe and gets final product.

The place that the utility model is made creative contribution for prior art mainly just is to be provided with a restriction end more, thereby can be so that the round end difficult drop-off in the door connector.So, protection domain of the present utility model is not restricted to this embodiment, can also in the protection domain of claim, make all equivalent variations that those skilled in the art inform, such as, in the specific implementation, can also a more than fixed end on the described frame connector, for example can be set to angle is two fixed ends of 90 degree, can be fixed on two inclines of doorframe by convenient its like this, the restriction end also can make independent design simultaneously, itself and frame connector are separated, only need its round end that plays in the limiting door connector to make its difficult drop-off get final product; For another example, the pivot in the utility model is optimum with cylindrical, but as others it is also belonged to protection domain of the present utility model as many plum-blossom-valve shapes or polygon-shaped etc.; Simultaneously, accompanying drawing 1 also should not be construed as the restriction to the utility model structure; Such as; in accompanying drawing 1; the link of door connector is the limit portion that is connected in round end; the tie point of frame connector and pivot also is the limit portion that is positioned at the restriction end; but during actual enforcement; the link of door connector also can be other position that is arranged at the link back; in like manner; the tie point of described frame connector and pivot also can be to be arranged at other inner positions of restriction end; only need during they both Position Design to guarantee: when the round end of door connector rotates; the restriction end of described frame connector can play the effect of restriction to it; making the door connector not come off with pivot gets final product; in addition in the specific implementation; can also be that it still can play the function of rotation and restriction with the installation site exchange of door link and frame link, this all be need be just not thinkable through creative work for those of ordinary skill in the art; this only is the change of mounting means, still should belong to protection domain of the present utility model.
