Referring to fig. 1 to 5, the present invention provides a large bearing gear structure hinge, which comprises the following embodiments:
in some embodiments, a large load bearing gear structure hinge is disposed between the frame and the sector for enabling opening and closing of the sector relative to the frame. Big bearing gear structure hinge includes bottom plate 100, the both ends are divided into first connecting rod 200 of first end and second end, the both ends are divided into the third connecting rod 400 of fifth end and sixth end, connection piece 500, bottom plate 100 is fixed to be set up on frame portion, connection piece 500 sets up on the fan portion, first connecting rod 200 and third connecting rod 400 are used for connection piece 500 and bottom plate 100, first end, the fifth end is the interval along the extending direction of bottom plate 100 and articulates in bottom plate 100, the second end, the sixth end is the interval along the extending direction of connection piece 500 and articulates in connection piece 500, when external force acts on the fan portion, drive the relative bottom plate 100 switching of connection piece 500 and locking.
Meanwhile, the end face of the first end is provided with an arc gear 220, and the bottom plate 100 is rotatably provided with a limit gear 120 engaged with the arc gear 220. The arc gear 220 is engaged with the limit gear 120 to limit the first link 200 from further rotating with respect to the base plate 100, and thus the maximum opening angle of the hinge is limited, thereby achieving the positioning of the maximum opening angle.
Further, the bottom plate 100 is further provided with an arc-shaped slot 110 which is through up and down, the arc-shaped slot 110 is arranged in an arc direction by taking a hinged position of the bottom plate 100 and the first end as a circle center, the first connecting rod 200 is provided with a first connecting piece 210, and the first connecting piece 210 and the arc-shaped slot 110 are arranged in a sliding manner. Wherein the first connecting member 210 may be a rivet or a sliding block, etc.
The arc-shaped slot 110 defines the motion track of the first connecting piece 210, and can define the rotation angle of the first connecting rod 200 around the bottom plate 100, and the rotation angle can be matched with the gear structure to form a hinge maximum opening angle double-positioning safety, meanwhile, the connecting point between the main load-bearing first connecting rod 200 of the hinge and the bottom plate 100 is increased, and the strength of the hinge is improved.
Further, when the fan drives the connecting piece 500 to open or close, the pushing force is too large, which is likely to cause damage. Therefore, the third link 400 is provided with a tooth socket 410 near the side of the limit gear 120, when the hinge is closed, the tooth socket 410 is engaged with the limit gear 120, the third link 400 presses the limit gear 120, and the limit gear 120 presses the arc gear 220 in the opposite direction, so as to prevent the hinge from rotating and opening.
At the moment when the hinge is opened, the connecting piece 500 acts on the second end and the third connecting rod 400 to rotate, meanwhile, the tooth groove 410 acts on the limiting gear 120, the limiting gear 120 acts on the arc gear 220, namely the first end, so that a linkage effect is achieved, and the hinge is not easy to damage; at the moment that the hinge is closed, the tooth grooves 410 are meshed with the limiting gear 120, the third connecting rod 400 presses the limiting gear 120, the limiting gear 120 reversely presses the arc-shaped gear 220, the first end of the first connecting rod 200 serving as a main bearing is locked by the limiting gear 120, and meanwhile, the second end of the first connecting rod 200 is locked by the connecting sheet 500, so that the hinge is not easy to damage, and the hinge can be prevented from being opened due to rotation.
Further, the third connecting rod 400 is provided with a clamping step 420, and the tooth groove 410 is formed in the step surface of the clamping step 420, so that when the third connecting rod 400, the connecting piece 500 and the bottom plate 100 are closed, the third connecting rod 400, the connecting piece 500 and the bottom plate 100 are rotated to the same straight line, and the overall width of the hinge is reduced. Meanwhile, when the first connecting rod 200 is bent towards the opening direction of the hinge with the large bearing gear structure, the third connecting rod 400, the connecting piece 500 and the bottom plate 100 are rotated to the same straight line when the hinge is closed, and the overall width of the hinge can be reduced.
In order to further increase the bearing capacity of the large-bearing gear structure hinge, the large-bearing gear structure hinge further comprises a second connecting rod 300, the two ends of the second connecting rod are divided into a third end and a fourth end, the third end is hinged to the bottom plate 100 and arranged between the first end and the fifth end, the fourth end is hinged to the third connecting rod 400, and the fourth end is arranged between the fifth end and the sixth end and bears the gravity applied to the third connecting rod 400 by the connecting piece 500, so that the auxiliary bearing effect is achieved, and the bearing capacity of the large-bearing gear structure hinge on large-sized and heavy-sized windows is enhanced. Two connection points are arranged between the main bearing first connecting rod 200 and the bottom plate 100, two connection points are arranged between the third connecting rod 400 and the bottom plate 100, and two connection points are arranged between the connecting piece 500 and the bottom plate 100 of the hinge, so that a movable five-connecting-rod hinge structure is formed.
In addition, the bottom plate 100 is provided with a first protrusion 103 and a second protrusion 104 at an interval along the extending direction of the bottom plate 100, a first end is hinged on the first protrusion 103, and a fifth end is hinged on the second protrusion 104. When the hinge is closed, when the third connecting rod 400, the connecting piece 500 and the bottom plate 100 rotate to the same straight line, the contact areas between the first connecting rod 200 and the third connecting rod 400 and the bottom plate 100 are reduced, so that the sliding friction is reduced, and the hinge runs more smoothly.
When the second link 300 is provided, the second link 300 is disposed between the third link 400 and the base plate 100, and between the first protrusion 103 and the second protrusion 104, and the protrusion height may provide a sufficient space for the second link 300, so that the thickness of the second link 300 may be increased to increase the structural strength of the second link 300, and finally, the load-bearing strength of the entire hinge may be improved.
Further, two ends of the connection sheet 500 are divided into a first connection end and a second connection end, the first connection end is provided with a bending portion 510, and the bending portion 510 is provided with a fixing hole 511. The bending part 510 is fixed on the side edge after wrapping the joint of the bottom and the side edge of the fan part. Thus, when the connector 500 is mounted, the connector 500 and the bending part 510 can be fixed relative to the fan part by a fixing structure such as screwing, and the connector 500 is prevented from falling off from the fan part; and can be quickly positioned by the matching of the bending part 510 and the top corner of the fan part, i.e. the joint of the bottom and the side.
Further, the hinged parts among the bottom plate 100, the first connecting rod 200, the third connecting rod 400 and the connecting piece 500 are all provided with gaskets 700, so that direct contact friction among the bottom plate 100, the first connecting rod 200, the third connecting rod 400 and the connecting piece 500 is avoided, and brass gaskets can be adopted specifically.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited thereto, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
