Detailed Description
In order to make the technical means, creation features, achievement purpose and efficacy of the present invention easy to understand, the following embodiments are combined with the accompanying drawings to specifically describe the hinge mechanism for elastically opening the cover plate, and it is necessary to describe that the description of these embodiments is used to help understand the present invention, but does not limit the present invention.
As shown in fig. 3 to 5, in the hinge mechanism 100 for elastically opening a cover plate in the present embodiment, an elastically opening cover plate (not shown in the drawings) is disposed on a housing part 5 mounted on a predetermined housing (not shown in the drawings) through a connecting pin 6, and has a connecting hinge 4 and an opening/closing hinge 1 hinged to each other through a hinge pin 7 and a torsion spring (not shown in the drawings), the connecting hinge 4 is disposed on the housing part 5 of the predetermined housing, the opening/closing hinge 1 is disposed on the elastically opening cover plate, the opening/closing hinge 1 is elastically triggered to rotate relative to the connecting hinge 4 by a point explosion, so that an included angle between the opening/closing hinge 1 and the connecting hinge 4 becomes larger, and the elastically opening cover plate is elastically opened relative to the predetermined housing, and the connecting hinge 4 and the opening/closing hinge 1 have a fixing buckle 8 and an elastic hook 9, respectively.
The opening and closing hinged member 1 is provided with a stopping waist groove 3, the connecting hinged member 4 is provided with a stopping screw 2 which is movably arranged in the stopping waist groove 3, and in the embodiment, the extending path of the stopping waist groove 3 is an arc segment which takes the hinge pin 7 as a circle center.
When the elastic opening cover plate is closed on the preset shell, the stop screw 2 is limited at one end of the stop waist groove 3, and the end is used as a closing limit end 31.
When the elastic opening cover plate is opened elastically relative to the preset shell, the stop screw 2 is limited at the other end of the stop waist groove 3, and the end is used as an opening limiting end 32.
The stopping waist groove 3 is provided with a buffering neck part 33, the buffering neck part 33 is positioned near the opening limiting end 32, the groove width of the stopping waist groove 3 at the buffering neck part 33 is smaller than the diameter of the stopping screw 2, the groove width of the rest part of the stopping waist groove 3 is larger than the diameter of the stopping screw 2, in the embodiment, the opposite side surfaces of the stopping waist groove 3 at the buffering neck part 33 are symmetrically and oppositely protruded, and therefore the groove width at the buffering neck part 33 is smaller than the groove width of the rest part of the stopping waist groove 3.
The rest part of the stop waist groove 3 except the buffer neck part 33 is used as a sliding groove section (not shown in the drawing), the sliding groove section between the opening limiting end 32 and the buffer neck part 33 is used as a support position 34, the length of the groove section of the support position 34 is less than or equal to the diameter of the stop screw 2, specifically, when the stop screw 2 is located in the support position 34, the buffer neck 33 stops and limits the stop screw 2 in the support position 34, and the stop screw 2 overcomes the stop limit of the buffer neck 33 to the elastic opening cover plate by applying external force to the elastic opening cover plate to close the elastic opening cover plate, i.e. the stop screw 2, enters or leaves the support location 34, the buffer neck 33 has a frictional resistance against it, therefore, the kinetic energy of the elastic opening cover plate is consumed, and through the arrangement, on one hand, the friction resistance of the buffering neck 33 to the stop screw 34 slows down the opening elasticity of the elastic opening cover plate, and the personal injury to personnel caused by the opening of the elastic opening cover plate is avoided; on the other hand, when the elastic opening cover plate is completely opened, the stop screw 2 is located in the support position 34, the stop force of the buffer neck 33 to the stop screw 2 enables the elastic opening cover plate to obtain a predetermined support force, and when the elastic opening cover plate needs to be closed, the elastic opening cover plate can be closed only by applying a predetermined external force to the elastic opening cover plate.
The above embodiments are preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and changes that can be made by those skilled in the art without inventive work within the scope of the appended claims will still fall within the scope of the present invention.
