Detailed Description

The utility model is further described below with reference to the accompanying drawings:

as shown in fig. 1 to 3, a hinge 100 includes a shaft seat 1 provided with a shaft hole 102 and a rotating shaft 2 installed in the shaft hole 102, and unlike the prior art, installation holes are provided on the shaft seat 1 and the rotating shaft 2, respectively. In the prior art, in order to facilitate installation and enlarge the stress area, a rotatable accessory mounting member is usually disposed on a shaft seat or a rotating shaft, and a mounting hole is formed in the accessory mounting member to fix the hinge 100. In the present application, the mounting holes are directly formed on the shaft seat 1 and the rotating shaft 2, so that the arrangement of accessory mounting parts is avoided, and the size of the hinge 100 is reduced.

In this application, the mounting hole provided on the shaft seat 1 is a screw hole 103. The shaft seat 1 is a rectangular body and is provided with a first mounting plane 101, and the threaded hole 103 is a blind hole with an orifice positioned on the first mounting plane 101. In this way, one end of the screw head of the screw can be mounted on the door frame or the cabinet frame 301, so that the influence on the appearance caused by the arrangement on the exposed shaft seat 1 is avoided, and the exposed surface of the shaft seat 1 is not provided with the screw head and the exposed hole. In the prior art, the threaded hole 103 is generally arranged on the door frame or the cabinet frame, the threaded end of the screw is screwed into the threaded hole 103, and one end of the screw head presses the accessory mounting piece of the shaft seat 1 to fix the shaft seat 1.

The mounting hole provided in the rotary shaft 2 is a through hole 206.

The rotating shaft 2 is divided into an upper rotating shaft 203 and a lower rotating shaft 204, the middle part of the upper rotating shaft 203 is provided with a limiting flange 205, a through hole 206 is formed in the upper section of the upper rotating shaft 203, the lower section of the upper rotating shaft 203 is inserted into the shaft hole 102 of the shaft seat 1, the middle part of the lower rotating shaft 204 is provided with a limiting flange 205, a through hole 206 is formed in the lower section of the lower rotating shaft 204, and the upper section of the lower rotating shaft 204 is inserted into the shaft hole 102 of the shaft seat 1. This arrangement facilitates assembly of the shaft seat 1 and the shaft 2. If the rotation shaft 2 is provided as a whole shaft, it cannot be assembled due to the existence of the limit flange 205.

The upper section of the upper rotating shaft 203 and the lower section of the lower rotating shaft 204 are provided with a second installation plane 201 perpendicular to the through hole 206, the outlet of the through hole 206 is positioned on the second installation plane 201, and the second installation plane 201 is a tangent plane of the outer peripheral surface of the limiting flange 205. In this way, the second mounting plane 201 is conveniently pressed against the door frame or the cabinet frame which is also plane, so that the upper rotating shaft 203 and the lower rotating shaft 204 are more firmly mounted.

The upper section of the upper spindle 203 and the lower section of the lower spindle 204 have a staple entrance plane 202 perpendicular to the through hole 206, the entrance of the through hole 206 being located on the staple entrance plane 202.

The edges of the shaft holes 102 on the upper end face and the lower end face of the shaft seat 1 are respectively provided with annular bosses 104 for limiting the limit flanges 205. In this way, during long-term rotation of the hinge 100, the limit flange 205 and the annular boss 104 wear away without rubbing the paint surfaces on the upper and lower end surfaces of the axle seat 1.

As shown in fig. 4, in the case of the hinge 100 of the present application, in order to adapt to a severe environment, the reinforced display must take corresponding protection measures for various factors affecting its performance, such as a system structure, electrical characteristics, and a mechanical and physical structure, etc., and is required to be in a closed state when in use, and be able to be rotated by 90 degrees like a cabinet door when in maintenance or when a cable is required to be plugged and unplugged. The display panel 4 of the ruggedized display is hinged to the cabinet 3 by a hinge 100.

Fig. 5 shows the display panel 4 of the ruggedized display when the display panel 4 is opened, in which the upper and lower shafts 203, 204 are fixed to the display panel 4, the shaft seat 1 is fixed to the cabinet frame 301 of the cabinet 3, and the screws are screwed into the threaded holes 103 of the shaft seat 1 through the cabinet frame 301 to fix the shaft seat 1.

Fig. 6 shows the display panel 4 closed, wherein the axle seat 1 is exposed, and the screw head and the screw hole are not visible on the axle seat 1, so that the exposed part of the axle seat 1 is smooth and beautiful.

The above embodiments are merely illustrative of the present utility model and several improvements or modifications, which can be made by others without departing from the principles of the present utility model, should be considered as falling within the scope of the present utility model.
