[0036] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.

[0037] This embodiment discloses as Figures 1 to 7An electric control cabinet with a detachable horizontal pulley structure is shown, including an electric control cabinet body 1. A base member 2 is provided at the inner bottom of the electric control cabinet body 1. L-shaped plug plates 7 are detachably inserted at the four corners on the peripheral side of the base member 2. A limiting frame 24 is integrally connected to the side of each L-shaped plug plate 7 facing away from the base member 2. A horizontal pulley member 3 is provided below the limiting frame 24. The horizontal pulley member 3 provides a moving function, enabling the electric control cabinet body 1 to move easily on a plane, facilitating handling and positioning. A fixed vertical rod 8 is connected above the horizontal pulley member 3. The fixed vertical rod 8 longitudinally penetrates the limiting frame 24 and extends to the outer side above the limiting frame 24. A horizontal L-shaped handle 4 is hinged to the inner wall of the L-shaped plug plate 7 above the limiting frame 24. The L-shaped handle 4 serves as an operation interface. By applying force to the L-shaped handle 4, the lifting and lowering of the horizontal pulley member 3 can be achieved, thereby controlling the height adjustment of the electric control cabinet body 1. The vertical corner of the L-shaped handle 4 is hinged to the top end of the fixed vertical rod 8 through a link adjustment mechanism 10. When force is applied to the L-shaped handle 4, the L-shaped handle 4 drives the fixed vertical rod 8 and the horizontal pulley member 3 to move up and down through the link adjustment mechanism 10, adjusting the position of the horizontal pulley member 3. The fixed vertical rod 8 serves as a connecting member, connecting the horizontal pulley member 3 and the L-shaped handle 4, transmitting the force, enabling the horizontal pulley member 3 to move with the operation of the L-shaped handle 4. When the L-shaped handle 4 is lifted by applying force, the L-shaped handle 4 drives the link adjustment mechanism 10 to rise, causing the link adjustment mechanism 10 to pull the fixed vertical rod 8 upward, thereby raising the horizontal pulley member 3. When the L-shaped handle 4 is pressed down by applying force, the L-shaped handle 4 drives the link adjustment mechanism 10 to descend, causing the link adjustment mechanism 10 to press down the fixed vertical rod 8 to descend in the limiting frame 24, causing the horizontal pulley member 3 to descend to the ground.

[0038] In this embodiment, the link adjustment mechanism 10 includes arc-shaped hinge plates 9 relatively hinged to both sides of the top end of the fixed vertical rod 8 through pins. The two arc-shaped hinge plates 9 are arranged centripetally and the top ends are hinged to the outer wall of the vertical corner of the L-shaped handle 4 through pins. The arc-shaped hinge plates 9 allow the hinge movement between the fixed vertical rod 8 and the L-shaped handle 4, ensuring the flexibility of the structure.

[0039] In this embodiment, hinge ear plates 25 are symmetrically welded to the upper part of the inner wall of the L-shaped plug plate 7. One end of the L-shaped handle 4 is hinged between two adjacent fixed vertical rods 8 through a pin. The L-shaped plug plate 7 provides a quick installation and disassembly method, facilitating the repair or replacement of the horizontal pulley member 3.

[0040] In this embodiment, an inverted U-shaped plate 6 is hinged to the upper part of the horizontal pulley member 3. The bottom end of the fixed vertical rod 8 is welded to the top surface of the U-shaped plate 6.

[0041] In this embodiment, the four corner inner walls of the base member 2 are welded with plug-in mounting boxes 5 for receiving the plug-in ends 13 of the L-shaped plug-in plates 7. The outer walls of each plug-in end 13 and the outer walls of the plug-in mounting boxes 5 are symmetrically defined with retaining openings 14. The plug-in mounting boxes 5 are used to secure the L-shaped plug-in plates 7 to the base member 2, ensuring a secure fit and facilitating removal and maintenance.

[0042] In this embodiment, a limiting elastic snap-fit assembly 11 is provided in the inner cavity of the plug-in end portion 13 , and the limiting elastic snap-fit assembly 11 extends into the limiting frame 24 and is in dynamic contact with the fixed upright pole 8 .

[0043] In this embodiment, the position-limiting elastic snap assembly 11 includes a position-limiting push rod 12 disposed transversely within the inner cavity of the insertion end 13, one end of which extends into the position-limiting frame 24; an extension rod 19 fixedly mounted to the other end of the position-limiting push rod 12; and a first position-limiting spring 20 sleeved around the circumference of the extension rod 19. As part of the position-limiting elastic snap assembly 11, the position-limiting push rod 12 contacts the fixed upright 8 within the position-limiting frame 24 to maintain structural stability.

[0044] In this embodiment, the extended insertion rod 19 extends away from the limiting push rod 12 and extends to the outside of the insertion end 13. One end of the first limiting spring 20 elastically abuts the inner wall of the insertion end 13. One end of the limiting push rod 12, located within the limiting frame 24, is provided with a mating abutment portion 16 that abuts against the outer wall of the fixed upright 8. The mating abutment portion 16 ensures close contact between the limiting push rod 12 and the fixed upright 8, improving the structural integrity. The first limiting spring 20 provides elastic force, allowing the limiting push rod 12 to automatically reset and maintain contact with the fixed upright 8.

[0045] In this embodiment, a limiting side push rod 21 is symmetrically connected to the middle position of the limiting push rod 12. The end of the limiting side push rod 21 located outside the limiting push rod 12 is sleeved with a second limiting spring 22. The end of the limiting side push rod 21 away from the limiting push rod 12 is connected to a limiting stopper 23. The outer wall of the limiting stopper 23 is connected to a limiting buckle 15. The second limiting spring 22 elastically abuts against the inner wall of the limiting stopper 23. The limiting buckle 15 is elastically engaged with the limiting opening 14 through the second limiting spring 22. The limiting buckle 15 fixes the L-shaped plug plate 7 by cooperating with the limiting opening 14, ensuring its stability during use.

[0046] In this embodiment, a hollow sleeve 18 is provided around the two limiting side push rods 21. The hollow sleeve 18 is connected to the limiting push rod 12 through it. A travel limit pin 17 is inserted into one end of the limiting push rod 12 located in the inner cavity of the limiting frame 24. The travel limit pin 17 can limit the retraction stroke of the limiting push rod 12 and prevent the limiting push rod 12 from retracting into the inner cavity of the plug-in end 13. When the L-shaped plug plate 7 is plugged into the inner cavity of the plug-in installation box 5 of the base member 2, the limiting buckle 15 also extends and snaps into the limiting openings 14 on both sides of the plug-in installation box 5. When the L-shaped plug plate 7 needs to be removed, it only needs to be pulled out with force, so that the limiting buckle 15 can slide out of the limiting opening 14 of the plug-in installation box 5, thereby completing the installation and removal of the L-shaped plug plate 7.

[0047] Working principle:

[0048] The electric control cabinet with a detachable horizontal pulley structure has an L-shaped plug-in plate 7 inserted into the plug-in installation box 5 on the base member 2 through the plug-in end 13, and is engaged with the limiting opening 14 on the plug-in installation box 5 through the limiting buckle 15 in the limiting elastic buckle assembly 11, ensuring that the L-shaped plug-in plate 7 is firmly installed. The fixed vertical rod 8 passes through the limiting frame 24 and is connected to the horizontal pulley member 3. The L-shaped handle 4 is hinged to the L-shaped plug-in plate 7 through the hinged ear plate 25, and is connected to the top of the fixed vertical rod 8 through the connecting rod adjustment mechanism 10.

[0049] When the electric control cabinet 1 needs to be moved, the user holds the L-shaped handle 4 and applies an upward force. The force is transmitted to the connecting rod adjustment mechanism 10 through the L-shaped handle 4, thereby driving the fixed vertical rod 8 to move upward. As the fixed vertical rod 8 rises, the horizontal pulley 3 also rises synchronously and leaves the ground. At this time, the electric control cabinet 1 is in a movable state. After the horizontal pulley 3 rises, the user can control the direction of the electric control cabinet 1 by pushing the L-shaped handle 4, so that the electric control cabinet 1 moves along a predetermined path. During the movement process, the fixed vertical rod 8 remains relatively stationary, while the L-shaped handle 4 swings as the moving direction of the electric control cabinet 1 changes, but does not affect the state of the horizontal pulley 3. The force is transmitted to the connecting rod adjustment mechanism 10 through the L-shaped handle 4, thereby driving the fixed vertical rod 8 to move downward. The descent of the fixed vertical rod 8 causes the horizontal pulley 3 to descend and contact the ground, and the electric control cabinet 1 returns to a stable and immobile state.

[0050] If the L-shaped inserting plate 7 needs to be removed for maintenance or replacement, the user needs to apply a certain pulling force to make the L-shaped inserting plate 7 overcome the resistance between the limiting buckle 15 in the limiting elastic buckle assembly 11 and the limiting opening 14. After pulling out the L-shaped inserting plate 7, the limiting buckle 15 slides out of the limiting opening 14, completing the disassembly process.

[0051] The user aligns the new L-shaped plug board 7 with the plug-in mounting box 5 on the base member 2 and inserts it. When the plug-in end 13 of the L-shaped plug board 7 approaches the plug-in mounting box 5, the limit buckle 15 automatically pops into the limit port 14 under the action of the second limit spring 22 to complete the installation.

[0052] It should be understood that those of ordinary skill in the art can make improvements or transformations according to the above description, and all such improvements and transformations shall fall within the protection scope of the appended claims of the present utility model.
