Hinge buffer structure

technical field

The utility model relates to a hinge, in particular to a hinge buffer structure which can effectively slow down the opening of a cover and prevent the cover from being violently oscillated due to rapid opening and causing damage to the cover.

Background technique

Hinges are widely used in various items with hinged lid structures, such as laptop computers, clamshell mobile phones, and clamshell trash cans.

The structure of the general traditional hinge is mainly provided with two fixed pieces, which are respectively fixed on the seat and the cover of the article, and rolled into a hollow cylinder on one side of the two fixed pieces, and then the two The hollow cylinders of the fixed pieces are overlapped so that a shaft can pass through the hollow cylinders of the two fixed pieces to form a hinge. With the use of the hinge, the base and the cover can be pivotally connected as one, and When the cover is lifted away from the seat, the cover can be at a certain angle; in addition, with the advancement of science and technology, various hinges with new functions have been developed, such as: hinges with automatic return function, adjustable Hinges that limit the angle of opening, hinges that can be adjusted in multiple directions, etc., are endless; however, the above-mentioned hinges lack a buffer structure, so that when the hinged cover is lifted off the seat, it is difficult to The force of opening is too large, the speed of opening the cover is too fast and other factors, resulting in violent vibration after the cover is opened, and the cover is naturally prone to cracking and damage under the influence of this vibration and oscillating force for a long time situation.

The designer tried to solve the problem that the hinged cover body was lifted off the base body due to the excessive force and fast speed of the cover, which caused the cover to break and be damaged. With the help of many years of manufacturing design experience and knowledge in this field, the utility model is finally created.

Detailed ways

In order to have a more complete and clear disclosure of the technical content, features and effects achieved by the utility model, the detailed description is given below, and please also refer to the disclosed drawings:

First of all, please refer to Figures 1 to 3, which is a hinge 1 of the present invention, which can be assembled at the junction of the seat body 2 and the cover body 3. It is provided with a shaft sleeve 11, and a shaft sleeve 11 is axially pierced with a A polygonal through hole 111, and an active buffer block 12 is provided at one end of the shaft sleeve 11. The active buffer block 12 is provided with a connecting section 121 corresponding to the shape of the through hole 111 of the shaft sleeve 11, so as to be provided with the cover body 3 on one side. The polygonal through hole 31 is connected and positioned, and then an elastic member 13 is fixedly connected to one end of the connecting section 121, and the other end of the elastic member 13 is fixed to an adjustment block 14, and a tool is provided at the end of the adjustment block 14. The polygonal locking part 141 is engaged with the through hole 21 corresponding to the shape of the locking part 141 of the adjustment block 14 provided on the seat body 2, and an inclined part 122 is connected at the other end of the connecting section 121;

Furthermore, a passive buffer block 15 is assembled in the polygonal through hole 111 of the shaft sleeve 11, and the passive buffer block 15 is provided with a positioning section 151 corresponding to the shape of the through hole 111 of the shaft sleeve 11, for abutting against the polygonal through hole 111. Positioning, so that the passive buffer block 15 only slides and displaces in the polygonal through hole 111, and the positioning section 151 is provided with an inclined surface 152 at one end for correspondingly abutting against the inclined section 122 of the active buffer block 12, and then on the positioning section The other end of 151 abuts against the acting end 161 of an oil pressure rod 16;

In addition, a rotary block 17 is provided at the other end of the shaft sleeve 11, and the rotary block 17 is provided with a sleeve portion 171 for socketing and combining with the shaft sleeve 11, and a polygonal connecting section 172 is connected to the sleeve portion 171 for connecting with the cover. The other side of the body 3 is provided with a through hole 31 corresponding to the shape of the connecting section 172 of the rotary block 17 for connection and positioning, and one end of the elastic member 18 is fixed at the other end of the connecting section 172 of the rotary block 17, and then connected to the other end of the elastic member 18. An adjustment block 19 is fixedly connected, and the end of the adjustment block 19 has a polygonal locking portion 191 for the through hole 21 of the seat body 2 corresponding to the shape of the locking portion 191 of the adjustment block 19 to engage with each other. .

According to this structure, as shown in Figures 1 to 4, when the cover 3 is opened under force, the cover 3 will drive the connected active buffer block 12 to rotate.
