Abstract

The utility model discloses an anti-pinch hinge which comprises a first hinge (1) and a second hinge (2). The first hinge (1) and the second hinge (2) are movably connected through a hinge. The anti-pinch hinge further comprises a third hinge (3), wherein the third hinge (3) is movably connected with the second hinge (2) through a shaft sleeve, the shaft sleeve (31) and a shaft core (21) which are matched with each other are respectively arranged at the connecting position between the shaft sleeve (31) and a shaft core (21), and the contact position of the shaft sleeve (31) and a shaft core (21) has tilted gradient, and the tilted gradient of the contact position is adjusted according to the door weight. The anti-pinch hinge is additionally provided with the third hinge compared with a traditional hinge, is simple in structure, effectively prevents fingers clamped in door cracks from being injured and is especially suitable for families with children and other places.

Description

Finger hinge

Technical field

The utility model relates to hinge, especially relates to a kind of finger hinge.

Background technology

Hinge is furniture copper gadget, is commonly called as hinge, often forms two foldings, connect two parts of furniture and can make it movable metalwork, as a kind of device for connecting or rotating, make door, lid or other tilting member can be so as to rotating, the pair of metal blade conventionally being connected by pin forms.

At present, traditional hinges that great majority are used are comprised of the first hinge and the second hinge, when crack between a door and its frame has object or hand, understand and be crushed accidentally, concerning family has child's user, use very dangerous especially.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of simple in structure, and can prevent from being placed on because of carelessness the finger hinge that the hand in crack between a door and its frame is crushed.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A kind of finger hinge is provided, comprise the first hinge and the second hinge, described the first hinge is that hinges is connected with the second hinge, also comprise the 3rd hinge, described the 3rd hinge is flexibly connected by axle sleeve with the second hinge, the junction of described the 3rd hinge and the second hinge is respectively arranged with axle sleeve and the axle core cooperatively interacting, the gradient of the contact position of described axle sleeve and axle core for tilting, and the gradient of the described contact position gradient regulates according to the weight of door.

Further, described the 3rd hinge is provided with counter sink, and the 3rd hinge is threaded with door by described counter sink, and described the first hinge is threaded with doorframe.

Further, be provided with the hole corresponding with described counter sink position on described the second hinge, the diameter in described hole is greater than the diameter of described counter sink.

Adopted technique scheme, the beneficial effects of the utility model are:

Compared with prior art, the finger hinge that the utility model provides than traditional hinge many 3rd hinge, in the situation that crack between a door and its frame does not have tong pressure, the second hinge and the 3rd hinge fit tightly, just as integral body, when crack between a door and its frame has object or hand, the 3rd hinge will rise and open with respect to the second hinge, alleviated the pressure of crack between a door and its frame, prevented that hand is by tong.The advantage such as that finger hinge of the present utility model has is simple in structure, practicality good and finger is effective.

Wherein: 1-the first hinge; 2-the second hinge; 21-axle core; 22-hole; 3-the 3rd hinge; 31-axle sleeve; 32-counter sink.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1, the preferred finger hinge of the utility model, comprise the first hinge 1 and the second hinge 3, described the first hinge 1 and the second hinge 2 are connected for hinges, also comprise the 3rd hinge 3, described the 3rd hinge 3 is flexibly connected by axle sleeve with the second hinge 2, and the junction of described the 3rd hinge 3 and the second hinge 2 is respectively arranged with axle sleeve 31 and the axle core 21 cooperatively interacting, and described axle sleeve 31 is the gradient of inclination with the contact position of axle core 21.

In preferred embodiment of the present utility model, described the 3rd hinge 3 is provided with counter sink 32, the 3rd hinge 3 is threaded with door by described counter sink 32, because the installing hole on the 3rd hinge 3 is counter sink 32, after being screwed into screw, the 3rd hinge 3 is still burnishing surface, can with the second hinge 2 good fit.Described the first hinge 1 is threaded with doorframe.

In preferred embodiment of the present utility model, on described the second hinge 2, be provided with the hole 22 corresponding with described counter sink 32 positions, the diameter in described hole 22 is greater than the diameter of described counter sink 32.In the time will turning the screw that connects the 3rd hinge 3 and door, can directly through hole 22, carry out, facilitated being screwed into of screw.

In preferred embodiment of the present utility model, there is the angle of an inclination contact position of described axle sleeve 31 and axle core 32, and this angle is to arrange according to the weight of door; If the weight of door is large, this angle is just milder; If the weight of door is lighter, this angle can be larger.Due to the gradient tilting, the 3rd hinge 3 has a down dip under self gravitation effect, fits together, in closed state with the second hinge 2.

As shown in Figure 2 and Figure 3, finger principle: the first hinge 1 is threaded with doorframe, the second hinge 2 is connected with the first hinge 1 hinges, and the 3rd hinge 3 one end are connected with the second hinge 2 axle sleeves, and the other end is threaded with door.At closing time, the left side of door can inwardly be rotated, and in the situation that crack between a door and its frame does not have tong pressure, the 3rd hinge 3 and the second hinge 2 fit tightly, just as integral body, as Fig. 2; When crack between a door and its frame has object or people, the left side of door can be subject to resistance, under inertial force, the right side of door will inevitably produce one outside active force, and original the 3rd hinge 3 and the second hinge 2 are to fit tightly, at this moment under outside effect, the 3rd hinge 3 starts to open around axle core 21, as Fig. 3, the pressure at crack between a door and its frame place will be alleviated like this, thereby prevents that hand from being crushed.

As mentioned above, the finger hinge that the utility model provides than traditional hinge many 3rd hinge, in the situation that crack between a door and its frame does not have tong pressure, the second hinge and the 3rd hinge fit tightly, just as integral body, when crack between a door and its frame has object or hand, the 3rd hinge will rise and open with respect to the second hinge, alleviated the pressure of crack between a door and its frame, prevented that hand is by tong.The advantage such as that finger hinge of the present utility model has is simple in structure, practicality good and finger is effective.

The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
