Description

Technical Field

[0001] The present invention relates to an electrical installation plate mechanism, belonging to the technical field of electrical equipment mounting brackets. Background Art

[0002] An electrical installation plate refers to a sheet metal plate used for installing electrical components, usually inside electrical cabinets and equipment benches. The present invention mainly studies the structure of the electrical installation plate inside the equipment bench.

[0003] The previous electrical installation plates had the following forms:

[0004] They were divided into two major categories: immovable type and movable type:

[0005] The immovable electrical installation plate was mainly vertically installed inside the equipment bench and fixed to the bench with screws, being immovable.

[0006] The movable type was mainly of the drawer type and could be pulled out like a drawer. Another type could be made into a flip type, that is, the electrical installation plate could be directly flipped out from the inside.

[0007] The above structural forms all had their respective structural defects:

[0008] Firstly, the immovable electrical installation plate was vertically installed inside the equipment bench, making maintenance and wiring very inconvenient. The drawer-type electrical installation plate was convenient for maintenance, but after the electrical installation plate was pushed in, the electrical components on the plate could not be seen, and the status of some signal lights could not be viewed by the operator immediately. Moreover, in appearance, the entire bench was not aesthetic. The flip-type electrical installation plate needed a large swivel arm because it was directly flipped out from the inside of the bench. After the electrical installation plate was flipped, the height difference from the workbench surface of the equipment bench was large, and the height of the electrical installation plate from the ground was low, which was not aesthetic and inconvenient for the operator to operate. Summary of the Invention

[0009] The purpose of the present invention is to provide an electrical installation plate mechanism to solve the defect of inconvenient flipping operation in the prior art.

[0010] An electrical installation plate mechanism includes:

[0011] A translation slide rail, on which an electrical plate fixing frame is slidably connected;

[0012] An electrical installation plate, the upper end of which is hinged to the top of the electrical plate fixing frame, and the lower end is connected to the side part of the bottom end of the electrical plate fixing frame through a rotary locking mechanism;

[0016] An unlocking spring is provided between the unlocking button and the lockable handle housing. Pressing the unlocking button causes the electrical plate positioning pins at both ends of the unlocking button to extend and retract outward.

[0017] Further, a sleeve for the electrical plate positioning pin to shuttle through is provided on the electrical mounting plate. A limiting rod is provided on the electrical plate positioning pin, and a return spring for contracting the electrical plate positioning pin inward is provided between the limiting rod and the sleeve.

[0018] Further, the translational locking mechanism includes a translational lock core provided at the upper part of the electrical plate fixing frame, and a translational lock tongue adapted to the translational lock core and movably connected to the electrical plate fixing frame;

[0019] A translational lock groove adapted to the translational lock tongue is provided on the translational slide rail;

[0020] The translational lock core is provided with a lock core support seat. One end of the translational lock core is connected to a spring mounting base through a lock core pushing spring, and the other end is connected to the electrical mounting plate.

[0021] Further, the translational lock tongue is provided with an inclined slot hole, and the translational lock core is provided with an inclined block adapted to the inclined slot hole; the inclined block moves left and right in the inclined slot hole to make the translational lock tongue move up and down.

[0022] Further, the rotational locking mechanism includes a rotational lock core provided at the lower part of the electrical plate fixing frame. A rotational slot is provided in the rotational lock core, and the rotational slot is provided with an arc-shaped opening, and a lock core lever adapted to the arc-shaped opening;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0037] As Figures 1-5 shown, an electrical installation board mechanism is disclosed, including:

[0038] A translation slide rail 2, and an electrical board fixing frame 4 is slidably connected to the translation slide rail 2;

[0039] The electrical installation board 6, the upper end of the electrical installation board 6 is hinged to the top of the electrical board fixing frame 4, and the lower end is connected to the side of the bottom end of the electrical board fixing frame 4 through a rotary locking mechanism 10;

[0040] A translation locking mechanism 11, the translation locking mechanism 11 is used to disengage the electrical installation board 6 from the rotary locking mechanism 10 and lock the electrical board fixing frame 4 to the translation slide rail 2;

[0041] A lockable handle 7, the lockable handle 7 is used to lock or unlock the electrical installation board 6.

[0042] The lockable handle 7 includes an electrical board positioning pin 23 provided on the electrical installation board 6, an unlocking button 26 adapted to the electrical board positioning pin 23, and a lockable handle housing 25;

[0043] An unlocking spring 27 is provided between the unlocking button 26 and the lockable handle housing 25. Pressing the unlocking button 26 causes the electrical board positioning pins 23 at both ends of the unlocking button 26 to extend and retract outward.

[0044] A sleeve (not marked in the figure) for the electrical board positioning pin 23 to shuttle through is provided on the electrical installation board 6. A limiting rod (not marked in the figure) is provided on the electrical board positioning pin 23. A return spring 30 for contracting the electrical board positioning pin 23 inward is provided between the limiting rod and the sleeve. In the lockable handle 7, manually press the unlocking button 26, and the positioning pin 23 is pulled by the contraction spring 24 and retracts inward, and finally disengages from the electrical board positioning block 22 to complete the unlocking of the electrical installation board 6. Conversely, the electrical installation board 6 can be locked.

[0045] The translation locking mechanism 11 includes a translation lock core 18 provided on the upper part of the electrical board fixing frame 4 and a translation lock tongue 17 adapted to the translation lock core 18 and movably connected to the electrical board fixing frame 4;

[0046] A translation lock groove 13 adapted to the translation lock tongue 17 is provided on the translation slide rail 2;

[0047] The translation lock core 18 is provided with a lock core support 16. One end of the translation lock core 18 is connected to a spring mounting base 14 through a lock core pushing spring, and the other end is connected to the electrical installation board 6.

[0048] The translation lock tongue 17 is provided with an inclined slot hole, and the translation lock core 18 is provided with an inclined block adapted to the inclined slot hole; the inclined block moves left and right in the inclined slot hole to move the translation lock tongue 17 up and down. After the electrical board fixing frame 4 is completely pulled out, the translation lock tongue 17 is aligned with the translation lock groove 13. At this time, if the electrical installation board 6 is flipped, the translation lock core 18 moves outward under the action of the lock core pushing spring 15. At the same time, the inclined surfaces of the translation lock tongue 17 and the translation lock core 18 interact with each other to push the translation lock tongue 17 upward. Finally, the translation lock tongue 17 is inserted into the translation lock groove 13 to complete the locking action of the electrical board fixing frame 4, and vice versa for unlocking.

[0049] The rotary locking mechanism 10 includes a rotary lock core 20 provided at the lower part of the electrical board fixing frame 4. A rotary slot is provided in the rotary lock core 20, and the rotary slot is provided with an arc-shaped opening, and a lock core lever 21 adapted to the arc-shaped opening is provided;

[0050] The electrical installation board 6 is provided with a T-shaped slot adapted to the T-shaped portion provided at the end of the rotary lock core 20.

[0051] The electrical board fixing frame 4 moves through the translation guide wheels 9 in the translation slide rail 2. The rotary lock tongue 19 and the rotary lock core 20 are fastened together by screws. During the process of pushing the electrical board fixing frame 4 outwards from the inside, the rotary lock tongue 19 is in a 90-degree vertical state with the notch of the T-shaped slot on the electrical installation board 6. At this time, the electrical installation board 6 cannot be separated from the rotary lock tongue 19 and is thus locked on the electrical board fixing frame 4. When the electrical board fixing frame 4 is pushed out in place, that is, pushed to the leftmost position shown in the figure, the rotary lock core 20 is provided with a chute and quickly rotates 90 degrees under the action of the lock core lever 21, driving the rotary lock tongue 19 to rotate 90 degrees synchronously. At this time, the rotary lock tongue 19 is in a parallel state with the notch of the T-shaped slot on the electrical installation board 6. At this moment, the electrical installation board 6 can be separated from the rotary lock tongue 19 to complete unlocking, and the electrical installation board 6 can be safely flipped.

[0052] The electrical installation board 6 and the top of the electrical board fixing frame 4 are connected by a flip hinge 3.

[0053] A self-locking telescopic strut 12 is provided between the electrical installation board 6 and the electrical board fixing frame 4.

[0054] The mechanism further includes an equipment bench 1. The translation slide rail 2 is arranged inside the equipment bench 1, and universal wheels 8 are provided at the bottom of the equipment bench 1.

[0055] Press and pull out the button on the lock handle 7 with force. At this time, the rotary locking mechanism 10 ensures that the electrical installation board 6 will not flip before it is completely pulled out.

[0056] The electrical installation board 6 and the electrical board fixing frame 4 are pulled out together toFigure 3 After reaching the position, the rotary locking mechanism 10 of the electrical installation plate 6 is opened, and the electrical installation plate 6 is allowed to rotate. At this time, when the locking handle 7 is pulled continuously, the electrical installation plate 6 will rotate clockwise around the pin shaft of the flipping hinge 3. Once the electrical installation plate 6 starts to rotate, the translational locking mechanism 11 becomes effective, locking the electrical plate fixing frame 4 so that it cannot move. The electrical installation plate 6 continues to rotate until it is parallel to the workbench surface. The self-locking telescopic strut 12 has a self-locking function and supports the electrical installation plate 6 to keep it horizontal. At this time, the electrical installation plate 6 and the tabletop of the equipment bench 1 are on the same horizontal plane, as Figure 5 shown.

[0057] The electrical installation plate 6 is placed back to Figure 3 the vertical position shown. At this time, the translational locking mechanism 11 is unlocked, and the electrical installation plate 6 is pushed further inward. After reaching the position, the locking handle 7 will lock the electrical installation plate 6.

[0058] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
