DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Specific embodiments are given below.

[0030] Please refer to Figures 1-5The utility model discloses a switch cabinet with adjustable folding step, including cabinet 1, the both sides of cabinet 1 outer wall are provided with accommodating cavity 2, the folding step mechanism 3 is movably assembled in accommodating cavity 2, the folding step mechanism 3 includes main body board 4, is seted up folding accommodating portion 5 on main body board 4, folding accommodating portion 5, the folding accommodating portion 5 is movably provided with step side plate 6, first step board 7, second step board 8, is seted up first storage 9 for assembling and accommodating first step board 7 on step side plate 6, still is seted up second storage 10 for assembling and accommodating second step board 8 on step side plate 6, one end of first step board 7 is rotatedly connected with the upper inner wall of first storage 9 through first rotating rod 11, the other end of first step board 7 is rotatedly connected with the lower inner wall of folding accommodating portion 5 through second rotating rod 12, one end of second step board 8 is rotatedly connected with the upper inner wall of second storage 10 through third rotating rod 13, the other end of second step board 8 is rotatedly connected with the lower inner wall of folding accommodating portion 5 through fourth rotating rod 14, the one side fixed setting of accommodating cavity 2 is seted up on main body board 4 pull handle 15, the control mechanism 16 for fixing and unlocking folding step mechanism 3 is seted up on main body board 4.In operation, the internal structure and electrical principle of the cabinet body 1 are consistent with those of the prior art switch cabinet, which will not be described here. In the daily arrangement scene of the switch cabinet, usually multiple groups of individuals are closely combined together. The outer wall of the cabinet body 1 is designed with a receiving cavity 2 on both sides. When the switch cabinet is combined and installed with the adjacent switch cabinet, the receiving cavities 2 on both sides can be connected to form a larger overall receiving space for accommodating the main plate 4 of the folding step mechanism 3. In the normal state, the folding step mechanism 3 is completely accommodated in the combined receiving cavity 2, and the components are closely fitted, without occupying additional space and maintaining the regularity of the appearance of the switch cabinet combination, without affecting the overall layout. When the left side of the switch cabinet needs to be repaired, debugged, or operated at a high position, the operator holds the handle 15 on the main plate 4 and pulls it out. Then the operator inserts his hand into the operation hole 31 and applies a leftward pulling force to the main plate 4. The main plate 4 starts to move to the left. With the movement of the main plate 4, the first step plate 7 starts to rotate in the first receiving part 9 with the first rotating rod 11 as the axis, and the other end rotates relative to the lower inner wall of the folding receiving part 5 with the second rotating rod 12 as the axis. At the same time, the second step plate 8 also rotates with the third rotating rod 13 and the fourth rotating rod 14 as the rotating axes in the second receiving part 10 and the folding receiving part 5, respectively. Through such a linkage rotating mechanism, the originally folded and accommodated step side plate 6, the first step plate 7, and the second step plate 8 gradually unfold, and finally form a continuous, stable, and climbable step structure for the operator to operate on the left side of the switch cabinet. Similarly, when the right side of the switch cabinet needs to be operated at a high position, the operator only needs to pull out the folding step mechanism 3 to the right. Through the design of the receiving cavities 2 on both sides, the adjacent switch cabinets share the folding step mechanism 3, and there is no need to prepare a climbing device for each group of switch cabinets, which greatly saves the space of the combined cabinet body as a whole. Compared with the traditional way of preparing a climbing facility for each group of switch cabinets, the operator only needs to simply pull open the folding step mechanism 3 to quickly obtain a usable climbing step, greatly shortening the preparation time and improving the work efficiency, so that the repair, maintenance, and other work can be carried out more timely and efficiently, and the operation method is uniform and convenient to grasp. In the non-use state, the folding step is completely hidden in the combined receiving cavity 2, and the appearance of the switch cabinet combination remains simple and regular, with strong coordination with the surrounding environment, without affecting the overall aesthetic appearance, meeting the requirements of modern industrial design for the cleanliness of the appearance of large-scale electrical equipment combination.

[0031] Further, the main plate 4 is provided with a control mechanism 16 for fixing and unlocking the folding step mechanism 3, the control mechanism 16 comprising an assembly groove 17 opened on the main plate 4 and located at one side of the top of the folding accommodating part 5, a locking pin 18 being slidably arranged in the assembly groove 17, a locking groove 19 being opened at one side of the top end of the step side plate 6 and matched with the locking pin 18, a movable hole 20 being opened on the handle 15 and extending through to the assembly groove 17, a moving rod 21 being slidably arranged in the movable hole 20, an installation groove 22 being opened on the inner wall of the movable hole 20, a spring 23 being terminated between the installation groove 22 and the moving rod 21 for returning the moving rod 21, a linkage column 24 being fixedly arranged on the locking pin 18, a driving slope 25 being opened at one end of the moving rod 21 and matched with the linkage column 24, and a button 26 being fixedly arranged at the other end of the moving rod 21; in working, when the operator pulls the folding step mechanism 3 out of the combined accommodating cavity 2, the step side plate 6 cannot be directly pulled out and stretched due to the initial limiting state of the control mechanism 16, if the subsequent unfolding operation is to be performed, the operator needs to press the button 26 on the handle 15, the button 26 drives the moving rod 21 connected thereto to slide in the movable hole 20 towards the locking pin 18, in this process, the moving rod 21 simultaneously stretches the spring 23 connected between the installation groove 22 and it, with the movement of the moving rod 21, the driving slope 25 at one end thereof continuously contacts the linkage column 24 on the locking pin 18, by virtue of the special inclination angle design of the driving slope 25, it applies an upward pushing force to the linkage column 24, thereby driving the locking pin 18 to gradually move upward, when the locking pin 18 moves upward to completely leave the locking groove 19 at one side of the top end of the step side plate 6, the limitation of the control mechanism 16 on the folding step mechanism 3 is successfully removed, at this time, the operator can smoothly further unfold the folding step mechanism 3, after unfolding, the button 26 is released, the stretched spring 23 drives the moving rod 21 to return to the original position along the movable hole 20 due to the elastic force of itself, being ready for the next operation, this design makes the unfolding process of the folding step mechanism 3 under the precise control of the operator, avoiding the unfolding of the step in unintended circumstances due to accidental or accidental pulling, effectively preventing possible safety hazards such as collision and injury.

[0032] Further, the bottom end of the locking pin 18 is provided with a driving surface 34 on both sides opposite to the opening and closing direction of the step side plate 6, and the top end of the step side plate 6 is provided with an arc-shaped chamfer 35 on both sides matched with the driving surface 34; in work, after the folding step mechanism 3 is successfully opened and the operator completes the high-altitude operation, it needs to be retracted into the folding accommodating part 5 for next use, the worker holds the step side plate 6 or uses the operating hole 31 for help, pulls the step side plate 6 to make it rotate to the folding accommodating part 5, with the step side plate 6 gradually approaching the folding accommodating part 5, the arc-shaped chamfers 35 on both sides of the top end of the step side plate 6 first contact the driving surfaces 34 on both sides of the bottom end of the locking pin 18, when the two contact, the step side plate 6 exerts an oblique upward component force on the locking pin 18, the component force pushes the locking pin 18 to overcome its gravity and start to move upward, under the continuous pulling of the operator, the step side plate 6 continues to go deep into the folding accommodating part 5, in this process, the locking pin 18 always keeps moving upward to avoid hindering the recovery of the step side plate 6, when the step side plate 6 completely enters the folding accommodating part 5, the locking pin 18 is just located above the locking groove 19 in space, at this time, because it loses the supporting component force of the step side plate 6, and the locking pin 18 is affected by gravity, it will naturally fall into the locking groove 19, and the folding step mechanism 3 is fixed and positioned again to ensure the stability in the storage state and prepare for the next rapid deployment and use.

[0033] Further, the outlet of the accommodating cavity 2 is fixedly provided with a limiting block 36 for limiting the main plate 4, and the top end side of the main plate 4 is provided with a plurality of fixed screw holes 27, one of which is threadedly connected with a limiting screw 28 matched with the limiting block 36; in use, during the daily use of the switch cabinet, when the operator pulls the handle 15 on the main plate 4, the main plate 4 starts to move outward, at this time, the limiting block 36 at the outlet of the accommodating cavity 2 plays a key limiting role, which can prevent the main plate 4 from being pulled out too much to separate from the accommodating cavity 2, ensure the folding step mechanism 3 to be unfolded within a controllable range, and ensure the safety of operation, and the cooperation of the plurality of fixed screw holes 27 and the limiting screw 28 provided on the top end side of the main plate 4 allows the operator to screw the limiting screw 28 into the fixed screw holes 27 at different positions according to the actual operation requirement, when the limiting screw 28 is fixed in the fixed screw hole 27 close to the handle 15, the main plate 4 is pulled out relatively short, which is suitable for some narrow space, and only part of the steps need to be unfolded to meet the climbing requirement, if the limiting screw 28 is fixed in the fixed screw hole 27 away from the handle 15, the main plate 4 can be pulled out longer, so that the distance between the folding step mechanism 3 and the cabinet 1 is increased, providing a wider and more ergonomic climbing step for the operator to meet the requirement of different height operation, and through this flexible limiting adjustment mode, whether it is a left switch cabinet or a right switch cabinet, it can be quickly adapted according to the site situation.

[0034] Further, the opposite surfaces of the folding accommodating portion 5 inner wall and the step side plate 6 on the main plate 4 are respectively provided with a first permanent magnet 29 and a second permanent magnet 30 with opposite magnetic poles, and the first permanent magnet 29 and the second permanent magnet 30 are provided with two groups of opposite magnetic poles; in use, when the folding step mechanism 3 is in the folded state, and the operator has operated the control mechanism 16 to release the limitation of the folding step mechanism 3 but has not operated the main plate 4, in order to prevent the main plate 4 from suddenly unfolding due to the loss of limitation and causing injury to the operator, the first permanent magnet 29 on the folding accommodating portion 5 inner wall and the second permanent magnet 30 on the opposite surface of the step side plate 6 will generate strong attractive force between each other due to the opposite magnetic poles, which will tightly attract the step side plate 6 to the folding accommodating portion 5 inner wall, so that the components of the folding step mechanism 3 are more closely fitted when being folded, further enhancing the overall structural stability of the folding step mechanism 3, and ensuring that it will not abnormally unfold when not being limited.

[0035] Further, the bottom end of the main plate 4 is rotatably equipped with pulleys 32 on both sides, facilitating the movement of the main plate 4, and the bottom end of the step side plate 6 is fixedly equipped with foot pads 33 on both sides; in operation, when the operator pulls out the main plate 4, the pulleys 32 on both sides of the bottom end of the main plate 4 will rotate, converting the sliding friction between the main plate 4, the bottom of the containing cavity 2 and the ground into rolling friction, greatly reducing the friction, so that the main plate 4 can be quickly and smoothly moved under the action of smaller external force, reducing the physical exertion of the operator, and when the folding step mechanism 3 is unfolded and used by the operator, the foot pads 33 on both sides of the bottom end of the step side plate 6 will be in close contact with the ground, and since the foot pads 33 are usually made of materials with good anti-skid performance, such as rubber, etc., they can provide stable standing support for the operator, effectively preventing slipping accidents caused by wet and slippery ground, oil stains and other factors, and ensuring the personal safety of the operator during the climbing operation, safe and worry-free for climbing operation on both left and right side switch cabinets.
