Description
Technical Field
The invention relates to a case, in particular to a front opening door hinge for a case, which is smooth in sliding and good in bearing capacity.
Background
The power supply equipment adopting the chassis as the shell is more and more, so that the front door panel of a plurality of power supply chassis is designed to be in an openable mode in the design process for facilitating the overhaul and maintenance of the power supply, and the most convenient opening mode is opened by adopting a hinge mode. Many previous power supply hinges have taken the form of the structure shown in the following figures. As shown in fig. 1, the rotating block 11 of the hinge is connected with the front door panel of the chassis, the slide rail 12 is connected with the body of the chassis, the slider 13 can slide in the positioning slot of the slide rail 12, and the rotating block 11 is hinged with the slider 13 through the short shaft 14 and can freely rotate around the short shaft 14, so as to realize the rotation of the front panel. When the front door panel is used, the front door panel of the case is pulled outwards along the depth direction of the case, the sliding block 13 slides forwards in the sliding way 12 to reach a front end stop point, and then the front door panel rotates to be opened by taking the rotating block 11 as a rotating fulcrum.
The main problems with such current hinges are;
1. the slider 13 is less constrained in the slideway 12, and is liable to have phenomena of unsmooth sliding, shaking, dislocation and the like during sliding (especially under the condition of long-term use and abrasion).
2. Because the hinges are usually used in pairs, if the resistances of the sliding blocks 13 of the two hinges are different, the consistency of the hinge action is poor, and phenomena such as stagnation, position deviation and the like occur when the front door panel is opened.
3. The hinge bearing is less, when the components and parts quality on the front panel is great, can lead to the whole tenesmus when the front door plant is opened.
In view of the above problems, the present invention should be improved upon with respect to the current design. The method solves the constraint problem of the sliding of the hinge sliding block and ensures the linear and stable sliding of the hinge sliding block. Secondly, the problem of the consistency of the hinges is solved, and the hinges are guaranteed to be stable and controllable when used in pairs. And thirdly, the bearing problem is solved, and the vertical stability of the front door panel after being pulled out is ensured.
