Description

Hinge structure

The present invention relates to a hinge structure having a cushioning function.

The hinge is a common hardware accessory, which is mainly used for the connection between the cabinet and the cabinet door in the furniture. The hinge with the spring device installed in the early stage has no buffering function, so the door of the spring device often appears due to the spring force of the spring device. The phenomenon of too fast opening and closing speed, the above phenomenon will cause the cabinet door to make a great sound when it is closed, and the cabinet will vibrate, and the inertia caused by the spring resilience when the door is opened will make the hinge installation part Looseness will cause the hinge to fall off in the long run, and in order to solve this problem, a hinge with a cushioning function is introduced. The hinge with cushioning function is mainly installed through a buffer cylinder, so that the door can be slowly opened and closed. To reduce the negative impact of the spring device resilience on the entire hinge.

The addition of the buffer cylinder can indeed reduce the resilience generated by the spring device during the hinge movement, but the initial resilience of the hinge can not be eliminated, so that the conventional buffer hinge still has poor stability during operation. The problem, but it is necessary to improve the innovator.

Therefore, the inventor of this inventor is in light of this, and the idea of thinking and creation is designed with many years of experience. After many discussions and trials of sample tests, and many revisions and improvements, it is launched. Bright.

Conventional buffered hinges have poor stability during operation, which is a technical problem to be solved.

The hinge structure of the present invention comprises a first connecting arm and a second connecting arm. The first connecting arm and the second connecting arm are pivotally connected with a hinge cup at one end and a fixed seat is pivotally connected to the other end. The hinge cup, the first connecting arm, the second connecting arm, and the continuous pivot group of the fixing base can be configured to provide a hinge, and the fixing seat has a buffer cylinder inside the movable pivot group, and the buffer cylinder is connected to the second The arm between the arms is completed by a link of the connecting rod, and the outer peripheral sleeve of the shaft for providing the pivotal group of the first connecting arm and the fixing base is provided with a torsion spring, and the second connecting arm is disposed on the second connecting arm And a support rod extending from a side of the second connecting arm, the support rod having a shaft and a head end, wherein the outer diameter is smaller than the shaft end of the head end and the second connecting arm One of the supporting legs of the torsion spring is pressed, and the other supporting leg of the torsion spring is abutted against the fixing seat; thereby, the hinge structure can be constructed.

(1) The hinge structure of the present invention, which uses the shaft of the support rod to provide the torsion spring for pressing, The focus point of the torsion spring is changed on the second connecting arm, thereby changing the magnitude of the elastic force applied to the second connecting arm, thereby balancing the switching speed of the hinge so that it can be evenly switched.

(2) The hinge structure of the present invention is provided with one of the support legs of the torsion spring provided by the shaft having an outer diameter smaller than the head end and the second connecting arm, so that the support leg is limited to a relatively enlarged Between the head end and the second connecting arm, the phenomenon that the supporting leg of the hinge can be released from the supporting rod due to unrestricted movement during the movement can be avoided, so that the stability and reliability of the hinge can be obtained.

In order to enable your review committee to have a better understanding and understanding of the purpose, features and effects of the present invention, please refer to the following [detailed description of the drawings] as follows: Generally, according to the present invention, please refer to the first to fifth As shown in the figure, the present invention provides a hinge structure including a first connecting arm (12) and a second connecting arm (13), A connecting arm (12) and one end of the second connecting arm (13) are pivotally connected with a hinge cup (11), and the other end is pivotally connected with a fixing seat (14), and the hinge cup (11) and the first connecting arm (12), the second connecting arm (13), the continuous pivot group of the fixing seat (14), can constitute a hinge (10) for use, and the fixing seat (14) has a buffer cylinder (15) And the connection between the buffer cylinder (15) and the second connecting arm (13) by using a link (16) to complete the pivoting group, and to provide the first connecting arm (12) and the fixing base (14) The outer peripheral sleeve of the shaft (17) of the pivoting group is provided with a torsion spring (18), and the second connecting arm (13) is provided with a side extending from the side of the second connecting arm (13). a support rod (19) having a shaft (191) and a head end (192), wherein the outer diameter is smaller than the head end (192) and the second connecting arm (13) The shaft (191) provides one of the support legs (181) of the torsion spring (18) for pressing, and the other support leg (181) of the torsion spring (18) abuts against the fixed seat (14) )on.

The present invention provides a hinge structure in which the second connecting arm (13) is composed of a plurality of stacked sheets (please also be viewed from the sixth drawing).

The present invention provides a hinge structure in which the link (16) is composed of two spaced apart sheets.

The present invention provides a hinge structure in which the head end (192) is enlarged relative to the shaft (191) so as to form an outer diameter on the support rod (19) smaller than the head end. (192) a shaft (191) with the second connecting arm (13).

The present invention provides a hinge structure in which the support rod (19) is directly formed with a ring groove on the shaft body (191), and the ring body is formed by the ring structure, so that the shaft body (191) The outer diameter can be significantly smaller than the head end (192) and the second connecting arm (13).
