The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

The embodiment provides a distribution box, including door frame, dodge gate and 180 degrees hidden hinges, 180 degrees hidden hinges are connected with door frame and dodge gate respectively.

Furthermore, a buffer pad is arranged on one side of the movable door close to the door frame, so that noise is reduced and the movable door is protected. The buffer cushion can reduce the noise and impact force when the movable door is closed, thereby preventing the movable door from deforming and prolonging the service life of the movable door. Of course, the present embodiment does not impose any limitation on the number and specific shape of the cushion pads as long as it can reduce noise and impact force when the movable door is closed.

Wherein, in order to guarantee the smooth switching of dodge gate, the dodge gate can set up corresponding clearance with the upper and lower extreme and the left and right ends of door frame.

Specifically, as shown in fig. 1, in order to make the opening angle of the movable door reach 180 degrees, the 180-degree hidden hinge comprises a base 1, a hinge body 2 and a bolt 3, wherein at least one side wall of the base 1 can be connected with the movable door; the hinge body 2 comprises a fixed part 21 and at least one sleeve 22 which are connected, the base 1 is positioned above or below the sleeve 22, and the outer wall of the fixed part 21, which is far away from the base 1, is connected with the door frame; the bolt 3 passes through the sleeve 22 and the base 1 in sequence, so that the base 1 is rotatably connected with the hinge body 2 through the bolt 3.

When the movable door is used, the base 1 is driven by the bolt 3 to rotate relative to the door frame, and the outer wall of the fixed part 21 far away from the base 1 is connected with the door frame, so that the condition that the movable door cannot be opened to 180 degrees due to mutual interference between the movable door and the door frame when the movable door rotates at a certain angle can be avoided. This 180 degrees hidden hinge simple structure, dismouting are easy, can make the opening angle of dodge gate reach 180 degrees under the prerequisite that does not influence original structure of block terminal and space, have solved because of the dodge gate opening angle not enough and be unfavorable for the problem that the maintainer overhauld.

In addition, because the 180-degree hidden hinge is hidden between the movable door and the door frame and has no exposed part, the movable door has the advantages of small silence, small falling angle amount of the door, stable contact between the door and the frame, no damage, good strength, no occupation of useful space and the like when the movable door is opened and closed.

Wherein, when the door plant is the angle steel, two adjacent lateral walls of base 1 can be connected with two inner walls of dodge gate simultaneously, have improved the stability that base 1 and dodge gate are connected.

Illustratively, the base 1 is fixedly connected with the movable door through welding.

Further, in order to increase the contact area between the base 1 and the movable door, the base 1 is prismatic.

Illustratively, the fixing portion 21 is fixedly connected with the door frame by means of screw connection.

Further, in order to increase the contact area between the hinge body 2 and the door frame, the fixing portion 21 is prismatic.

Wherein, the fixing portion 21 is provided with a mounting hole, and the fastener is in threaded connection with the doorframe through the mounting hole. Of course, the number and specific positions of the mounting holes are not limited in this embodiment, and the mounting holes can be set according to actual requirements.

Illustratively, the fasteners are screws or bolts.

In this embodiment, in order to enable the base 1 to drive the movable door to rotate stably, the number of the sleeves 22 is two, and the base 1 is disposed between the two sleeves 22.

Further, the sleeve 22 and the fixing portion 21 are integrally formed. That is, the side of the fixing portion 21 close to the base 1 is rolled inward to form the sleeve 22, so that the manufacturing process is simplified, not only can the synchronous matching of the two sleeves 22 be ensured, but also the compactness of the overall size of the 180-degree hidden hinge can be improved. In other embodiments, the sleeve 22 and the fixing portion 21 may be welded together, and the embodiment is not particularly limited.

Wherein, be provided with the through groove 211 of anticollision on the fixed part 21, the extending direction that the groove 211 was led to in the anticollision is parallel with the axial direction of bolt 3 for settle the lateral wall of the dodge gate when opening angle is 180 degrees, avoid the dodge gate to rotate the in-process take place and take place to interfere between the door frame.

Illustratively, the cross-sectional shape of the anti-collision through slot 211 is L-shaped.

Illustratively, the base 1 is made of a carbon steel material.

Illustratively, the hinge body 2 is made of a zinc alloy material.

Illustratively, the plug pin 3 is round steel.

Optionally, the bottom of the plug pin 3 is a conical surface, and the outer diameter of the conical surface is gradually reduced from top to bottom, so that the plug pin 3 passes through the sleeve 22 and the base 1 to play a guiding role.

The assembly process of the distribution box of the utility model is as follows: base 1 and dodge gate fixed connection through the welding mode to make hinge body 2's fixed part 21 and door frame fixed connection through the mode of spiro union, two sleeves 22 are located base 1's top and below respectively this moment, pass sleeve 22 and base 1's bolt hole with bolt 3 again, make two sleeves 22 and base 1 coaxial coupling, thereby make the dodge gate hide the assembly of hinge and door frame through 180 degrees and accomplish, and then dodge gate and door frame 2 have just made up into the block terminal that can open 180 degrees.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
