DETAILED DESCRIPTION

[0023] In order to make the technical scheme of the present application or the prior art clearer, the drawings needed in the prior art description will be briefly introduced as follows.

[0024] Example one, as Figures 1-7 ​​As shown, a sliding cover type quick-opening door mechanism includes a door cover 1, which is movably installed on the door frame 19 on the front side of the distribution box 2. An upper lifting block 3 and a lower lifting block 4 are respectively installed on the left side of the front surface of the door cover 1. A disc 5 is provided between the upper lifting block 3 and the lower lifting block 4. The upper edge and lower edge of the disc 5 are tangent to the lower surface of the upper lifting block 3 and the upper surface of the lower lifting block 4, respectively. A shaft groove 6 is opened on the outer periphery of the disc 5. A handle 7 is fixedly installed on the front surface of the disc 5. Two rotating shaft supports 8 are vertically installed on the left side of the front surface of the door frame 19. A rotating shaft 9 is rotatably connected between the two rotating shaft supports 8. A support shaft 10 is horizontally installed in the middle of the rotating shaft 9. The support shaft 10 is movably engaged in the shaft groove 6.

[0025] A door support 11 is installed on the left side of the front surface of the door cover 1, and a door hinge 12 is vertically fixedly installed on the left side of the front surface of the door frame 19. The door support 11 is movably sleeved on the outer surface of the door hinge 12, and the pivot 9 is coaxial with the door hinge 12. Limiting blocks 13 are fixedly installed on both the left and right sides of the rear surface of the door cover 1, and slots 14 are provided on both the left and right sides of the rear surface of the door frame 19. The slots 14 cooperate with the limiting blocks 13.

[0026] Working principle:

[0027] When opening the door, first install the disc 5 between the upper lifting block 3 and the lower lifting block 4, ensuring that the shaft groove 6 on the outer edge of the disc 5 engages with the outer surface of the support shaft 10. Then, lift the handle 7 upwards, causing the entire handle 7 and the disc 5 to rotate upwards around the support shaft 10 to a horizontal position. Figure 7 As shown, at this time, by lever principle, the tangent between the disc 5 and the lower surface of the upper lifting block 3 can be used to drive the disc 5 to rotate upward around the support shaft 10 through the handle 7, thereby pushing the upper lifting block 3 to move upward; thus driving the entire door cover 1 to move upward; during this process, the door support 11 on the door cover 1 will also move upward along the axial direction of the door shaft 12.

[0028] When the handle 7 is rotated counterclockwise to the horizontal position, the door cover 1 moves upward by approximately 20mm. At this point, the limiting block 13 can disengage from the slot 14, allowing the door to open. During the opening action, the entire door cover 1 rotates around the door hinge 12. In this embodiment, the support shaft 10 is mounted on the rotating shaft 9, which can rotate coaxially with the door hinge 12 between two rotating shaft supports 8. Therefore, the disc 5 and the handle 7 can rotate together with the door cover 1. This ensures that the door cover 1 does not suddenly fall off when the disc 5 and handle 7 rotate simultaneously with the door cover 1. Furthermore, when closing the door, the groove 6 on the outer edge of the disc 5 can be quickly engaged with the support shaft 10 in the middle of the rotating shaft 9.

[0029] Similarly, when the closing action is performed, the handle 7 is first rotated to the horizontal position, so that the clamping protrusions 132 of the limiting block 13 correspond to the strip-shaped notches 141 of the clamping groove 14, so that the limiting block 13 can be rotated into the clamping groove 14; then the door cover 1 is rotated about the door shaft 12 to the closed state, and then the handle 7 is rotated clockwise to the initial position, at which time the entire door cover 1 also slides downward, so that the limiting block 13 and the clamping groove 14 are clamped to achieve the closing and locking effect of the door cover 1.

[0030] When the use is completed, the entire disc 5 and the handle 7 can be directly taken out from between the upper lifting block 3 and the lower lifting block 4, so that the entire disc 5 and the handle 7 are used as keys, thereby effectively reducing the space occupancy rate of the front side of the distribution box body 2.

[0031] In the second embodiment, as a further preferred solution of the first embodiment, the door shaft 12 and the door support 11 are both provided with two groups, two door shafts 12 are respectively fixedly installed above and below the left side of the front surface of the door frame 19, the door shaft 12 comprises a support seat 121 and a shaft 122, the shaft 122 is vertically fixedly installed above the support seat 121, and the door support 11 is movably sleeved on the outer surface of the shaft 122. By providing two groups of door shafts 12 and door supports 11, the stability of the entire door cover 1 during rotation is effectively ensured.

[0032] In the third embodiment, as a further preferred solution of the first embodiment, the limiting block 13 comprises an integrated installation block 131 and a plurality of clamping protrusions 132, the installation block 131 is fixedly installed on the rear side of the door cover 1, the clamping protrusions 132 are equally spaced on the side of the installation block 131, the edge of the clamping groove 14 is equally spaced to form a plurality of strip-shaped notches 141, and the clamping protrusions 132 are movably matched with the strip-shaped notches 141.

[0033] Therefore, when the handle 7 is counterclockwise rotated to the horizontal position, the position of the clamping protrusion 132 corresponds to the position of the strip-shaped notch 141, so that the clamping protrusion 132 can directly pass through the strip-shaped notch 141, thereby ensuring that the limiting block 13 can be separated from the clamping groove 14. Similarly, when in the closed state, the height position of the clamping protrusion 132 can be corresponded to the height position of the strip-shaped notch 141, so that the clamping protrusion 132 can pass through the strip-shaped notch 141, thereby making the limiting block 13 rotate to the position inside the clamping groove 14 again, and making the entire door cover 1 slide downward again, so that the limiting block 13 is clamped with the clamping groove 14 again, thereby achieving the closing and locking effect of the door cover 1.

[0034] In the fourth embodiment, as a further preferred solution of the first embodiment, a limiting holder 15 is fixedly installed on the upper side of the rear side of the door cover 1, a plurality of limiting grooves 151 are formed on the lower surface of the limiting holder 15, and an upper clamping block 16 is installed on the upper side of the front side of the door frame 19, and the limiting grooves 151 correspond to the upper clamping block 16 in an up-down manner.

[0035] Therefore, when the handle 7 is counterclockwise rotated to the horizontal position, the whole door cover 1 is moved upward, at this time, the limiting holder 15 is also moved upward, so that the limiting grooves 151 on the lower surface of the limiting holder 15 are separated from the upper clamping block 16, thereby enabling the door cover 1 to be outward rotated and opened. When the door cover 1 is closed, the door cover 1 is first inward rotated to the position of abutting against the door frame 19, and then the handle 7 is clockwise downward rotated, so that the whole door cover 1 is moved downward, at this time, the limiting grooves 151 on the lower surface of the limiting holder 15 are just clamped on the upper clamping block 16, thereby enabling the door cover 1 to be further clamped and locked by the upper clamping block 16. The stability of the closed door cover 1 is further ensured.

[0036] In the fifth embodiment, as a further preferred solution of the first embodiment, a lower clamping block 17 is fixedly installed on the lower side of the rear side of the door cover 1, and a lower clamping block connecting groove 18 is formed on the lower surface of the rear side of the door frame 19, and the lower clamping block 17 is movably clamped with the lower clamping block connecting groove 18 in an up-down manner.

[0037] Therefore, when the handle 7 is counterclockwise rotated to the horizontal position, the whole door cover 1 is moved upward, at this time, the lower clamping block 17 is synchronously moved upward with the door cover 1, thereby enabling the lower clamping block 17 to be separated from the lower clamping block connecting groove 18, and then the lower clamping block 17 will not affect the door opening action of the door cover 1, and when the door cover 1 is closed, the lower clamping block 17 is synchronously moved downward with the door cover 1, at this time, the lower clamping block 17 is just clamped on the lower clamping block connecting groove 18, thereby enabling the door cover 1 to be further clamped and locked by the lower clamping block 17. The stability of the closed door cover 1 is further ensured.

[0038] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements will not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
