[0001] This utility model relates to the field of low-voltage switchgear technology, and in particular to a quick-plug connection structure for drawer-type low-voltage switchgear. Background Technology

[0002] As a key piece of equipment in low-voltage power distribution systems, drawer-type low-voltage switchgear is widely used in power distribution and control in industrial sites, commercial buildings, and residential buildings. It is used to receive, distribute, control, and protect electrical energy. It can flexibly transmit electrical energy to various branches according to different power demand. Its drawer-type structure design makes the installation, maintenance, and replacement of internal electrical components more convenient, greatly improving the reliability and maintainability of power system operation.

[0003] Traditional drawer-type low-voltage switchgear connection mechanisms mainly consist of bolts, nuts, and matching terminals. During use, operators need to use a screwdriver to insert the bolts through the corresponding mounting holes on the drawer cabinet and the cabinet, then tighten the nuts. This electrical and mechanical connection is achieved by continuously tightening the nuts. This method has many drawbacks, the most prominent being its extremely complex operation. Tightening the screws not only consumes a lot of time and physical effort but also requires a high level of operator skill. Existing technology uses plug-in connectors and sockets to replace the bolt and nut connection. This improved connection structure simplifies the process by simply aligning the plug-in connector of the drawer-type switchgear with the socket on the cabinet and inserting it directly. However, in actual use, the sliding connection between the drawer cabinet and the cabinet using a sliding slider results in significant friction when plugging and unplugging the drawer cabinet, requiring considerable physical effort during major maintenance. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a quick-plug connection structure for drawer-type low-voltage switchgear, which aims to improve the problem in the prior art where the sliding connection between the drawer cabinet and the cabinet is made by a sliding slider with a groove, resulting in large friction when plugging and unplugging the drawer cabinet, and requiring a lot of physical effort during large-scale maintenance.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drawer-type low-voltage switchgear quick-plug connection structure, including a cabinet body. Multiple drawer slots are provided on both the upper and lower sides of the cabinet body. Drawer cabinets are slidably connected to the inner walls of the multiple drawer slots. Multiple rollers are rotatably connected to the left and right sides of the inner walls of the multiple drawer slots. Two slide rails are provided on the left and right sides of the outer walls of the multiple drawer cabinets. The multiple slide rails are slidably connected to the corresponding rollers. Handles are fixedly connected to the left and right sides of the front end of the outer wall of the drawer cabinet. Slide rails are provided on the left and right sides of the front end of the outer wall of the drawer cabinet. The sliding groove has multiple sliding grooves, each with a sliding push rod slidably connected to its inner wall. The front ends of each push rod pass through the corresponding handle. Each drawer cabinet has a reserved groove at its bottom, with a plug rod slidably connected to the inner wall of each reserved groove. Each push rod is slidably connected to the plug rod, and a spring is fixedly connected to the top of each plug rod. Each drawer groove has slots on the left and right sides of its inner bottom wall, with each plug rod slidably connected to the corresponding slot. The bottom of the cabinet is equipped with a moving mechanism for moving the cabinet.

[0006] As a further description of the above technical solution: the moving mechanism includes multiple hollow tubes, which are respectively fixedly connected to the four corners of the bottom of the cabinet. Threaded rods are slidably connected to the inner walls of the multiple hollow tubes. Slider blocks are fixedly connected to the left and right sides of the outer walls of the multiple threaded rods. Sliding grooves are opened on the left and right sides of the inner walls of the multiple hollow tubes. Rotating sleeves are rotatably connected to the tops of the multiple hollow tubes. The multiple rotating sleeves are respectively threadedly connected to the corresponding threaded rods. Foot pads are fixedly connected to the bottom ends of the multiple threaded rods. Moving wheels are fixedly connected to the four corners of the bottom of the cabinet.

[0007] As a further description of the above technical solution: a mounting base is fixedly connected to the top of the cabinet, and an alarm light is connected to the inner arc top of the mounting base.

[0008] As a further description of the above technical solution: an information board is fixedly connected to the front side of the outer wall of the cabinet, and screws are threaded around the outer wall of the information board, with the rear ends of the screws being threaded to the cabinet.

[0009] As a further description of the above technical solution: each of the outer walls of the multiple drawer cabinets is rotatably connected to a control handle, and the surfaces of the multiple control handles are treated with anti-slip coating.

[0010] As a further description of the above technical solution: a display screen is fixedly connected to the right side of the front end of the outer wall of each of the multiple drawer cabinets, and the surface of each of the multiple display screens is treated with wear resistance.

[0011] As a further description of the above technical solution: the surfaces of the plurality of rollers are all smoothed, and the spacing between adjacent rollers is equal.

[0012] As a further description of the above technical solution: each of the screws has a cross groove at its front end, and the inner wall of each cross groove is treated with wear resistance.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the rollers on the inner wall of the drawer slot and the sliding track on the outer wall of the drawer cabinet enable easy insertion and removal of the drawer cabinet, significantly reducing friction and improving the problem of high friction in existing sliding block connections. This also reduces physical exertion during major maintenance. The pressing rod, inserting rod, and spring work together; when the drawer cabinet is inserted into place, the spring pushes the inserting rod into the slot, achieving a stable connection and preventing accidental slippage. To remove the drawer, simply press the pressing rod. This convenient operation solves the problems of complex connection operations and unstable fixation in existing technologies.

[0015] In this invention, the rotating sleeve at the top of the hollow tube is connected to the threaded rod by a threaded connection structure. By rotating the rotating sleeve, the rotational motion is converted into the linear motion of the threaded rod by the threaded transmission, which drives the bottom foot pads to rise and fall, thereby adjusting the height of the cabinet. This allows it to adapt to different ground conditions and stabilize the cabinet. At the same time, the movable wheels at the four corners at the bottom of the cabinet give the cabinet the ability to move as a whole, making it easy to move between different locations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a drawer-type low-voltage switchgear quick-plug connection structure, including a cabinet 1, which provides an installation base and support for other components. Multiple drawer slots 3 are provided on the upper and lower sides of the cabinet 1 to provide specific installation positions for drawer cabinets 4. Drawer cabinets 4 are slidably connected to the inner walls of the multiple drawer slots 3, serving as carriers for electrical components and other equipment. Insertion and extraction operations can be performed within the drawer slots 3, facilitating equipment use and maintenance. Multiple rollers 5 are rotatably connected to the left and right sides of the inner walls of the multiple drawer slots 3, reducing friction during insertion and extraction of the drawer cabinets 4. Two slide rails 6 are provided on the left and right sides of the outer walls of the multiple drawer cabinets 4. The slide rails 6 cooperate with the rollers 5 to provide rolling tracks for the rollers 5, ensuring the stability of the drawer cabinets 4's sliding. The multiple slide rails 6 are slidably connected to the corresponding rollers 5. Handles 7 are fixedly connected to the left and right sides of the front end of the outer wall of the drawer cabinets 4, and sliding grooves 8 are provided on the left and right sides of the front end of the outer wall of the drawer cabinets 4. The sliding groove 8 provides sliding space for the pressing rod 9. The inner walls of multiple sliding grooves 8 are slidably connected to the pressing rod 9, which is used to control the movement of the insert rod 11 to realize the connection and separation between the drawer cabinet 4 and the cabinet body 1. The front end of multiple pressing rods 9 passes through the corresponding handle 7, which makes it convenient for the operator to operate the pressing rod 9 while holding the handle 7, thus improving the convenience of operation. The bottom of multiple drawer cabinets 4 is provided with a reserved groove 10. The inner walls of multiple reserved grooves 10 are slidably connected to the insert rod 11. Multiple pressing rods 9 are slidably connected to multiple insert rods 11 respectively. The top of multiple insert rods 11 is fixedly connected to a spring 12. The bottom left and right sides of the inner walls of multiple drawer grooves 3 are provided with slots 13. Multiple insert rods 11 are slidably connected to the corresponding slots 13 respectively. The insert rods 11 and slots 13 cooperate to realize the mechanical locking between the drawer cabinet 4 and the cabinet body 1, preventing the drawer cabinet 4 from accidentally sliding out during use. The bottom of the cabinet body 1 is provided with a moving mechanism 2, which is used to move the cabinet body 1.

[0027] Specifically, the cabinet body 1 serves as the overall frame, with drawer slots 3 on its upper and lower sides providing installation and sliding space for the drawer cabinet 4. This determines the layout of the switch cabinet and the number of drawers. Rollers 5, rotatably connected to the inner walls of the drawer slots 3, slidably connect to the slide rails 6 on the outer walls of the drawer cabinet 4, converting the sliding friction between the drawer cabinet 4 and the cabinet body 1 into rolling friction of the rollers 5. This significantly reduces friction, making the insertion and removal of the drawer cabinet 4 easier and smoother. Handles 7, fixed to the left and right sides of the front end of the outer wall of the drawer cabinet 4, facilitate the operator's application of force to pull out the drawer cabinet 4. A pressing mechanism runs through the handle 7. The rod 9 is slidably connected to the sliding groove 8 at the front end of the outer wall of the drawer cabinet 4, which facilitates the operator's control of the pressing rod 9. The pressing rod 9 is also slidably connected to the insert rod 11 in the reserved groove 10 at the bottom of the drawer cabinet 4. By pressing the rod 9, the insert rod 11 is squeezed, and the spring 12 connected to the top of the insert rod 11 provides elastic force. When the drawer cabinet 4 is inserted into the drawer groove 3, the spring 12 pushes the insert rod 11 downward into the slot 13 at the bottom of the inner wall of the drawer groove 3, realizing a stable mechanical connection between the drawer cabinet 4 and the cabinet body 1 and preventing the drawer from sliding out accidentally. When it is necessary to pull out the drawer, pressing the pressing rod 9 overcomes the elastic force and makes the insert rod 11 disengage from the slot 13.

[0028] Reference Figure 1 , Figure 6 and Figure 7 The moving mechanism 2 includes multiple hollow tubes 201, which are fixedly connected to the four corners of the bottom of the cabinet 1, serving as support and positioning, and providing an installation base for components such as threaded rods 202. Threaded rods 202 are slidably connected to the inner walls of each hollow tube 201. Height adjustment is achieved by sliding within the hollow tubes 201 to adapt to different ground conditions. Slider blocks 203 are fixedly connected to the left and right sides of the outer walls of each threaded rod 202, cooperating with grooves 204 to restrict the radial movement of the threaded rods 202. Grooves 204 are also provided on the left and right sides of the inner walls of each hollow tube 201 for the sliders. 203 provides a sliding track, and the top of multiple hollow tubes 201 are rotatably connected to rotating sleeves 205. The multiple rotating sleeves 205 are respectively threadedly connected to the corresponding threaded rods 202. This threaded connection method allows the threaded rods 202 to move up and down according to the direction of rotation when rotating the rotating sleeves 205. The bottom ends of the multiple threaded rods 202 are fixedly connected to foot pads 206, which are in contact with the ground. The height of the cabinet 1 can be adjusted by raising and lowering the threaded rods 202. The four corners of the bottom of the cabinet 1 are fixedly connected to casters 207, which allows the cabinet 1 to be flexibly moved between different positions to meet the needs of different work scenarios.

[0029] Specifically, the multiple hollow tubes 201 fixed at the four corners of the bottom of the cabinet 1 serve as the supporting foundation for the entire moving mechanism 2, providing installation positions for other components and bearing the weight of the cabinet 1. The sliders 203 fixed to the left and right sides of the outer wall of the threaded rod 202 cooperate with the sliding grooves 204 opened on the left and right sides of the inner wall of the hollow tube 201. The sliders 203 slide within the sliding grooves 204. This structural design ensures that the threaded rod 202 can only move stably axially within the hollow tube 201, preventing radial wobbling during adjustment, thus ensuring the stability and accuracy of the adjustment process. The rotating sleeve 205 rotatably connected to the top of the hollow tube 201 is threadedly connected to the threaded rod 202, forming a height adjustment transmission device. When the rotating sleeve 205 is rotated, due to the transmission principle of the thread, the rotating sleeve... The rotational motion of 205 is converted into the vertical linear motion of the threaded rod 202. Thus, the length of the threaded rod 202 extending out of the hollow tube 201 can be easily adjusted through simple rotation. The foot pad 206, fixedly connected to the bottom of the threaded rod 202, directly contacts the ground. As the threaded rod 202 rises or falls, the foot pad 206 also rises or falls accordingly, thereby achieving fine-tuning of the cabinet 1's height. This is especially important when the ground is uneven. By adjusting the height of each threaded rod 202, the cabinet 1 can be kept level, ensuring the normal operation of the internal equipment. The casters 207 provide convenience for moving the cabinet 1, allowing operators to easily push it to move it between different positions to meet the needs of different work scenarios, greatly improving the flexibility of the switchgear.

[0030] Reference Figure 1 , Figure 2 and Figure 4 A mounting base 14 is fixedly connected to the top of the cabinet 1. An alarm light 15 is connected to the inner arc top of the mounting base 14. When the switch cabinet malfunctions, the alarm light 15 will light up to alert the staff. An information board 16 is fixedly connected to the front of the outer wall of the cabinet 1 to display switch cabinet information. Screws 17 are threaded around the outer wall of the information board 16, and the rear ends of the screws 17 are threaded to the cabinet 1. A control handle 18 is rotatably connected to the front of the outer wall of the multiple drawer cabinets 4. Rotating the control handle 18 controls the operation of the equipment inside the drawer cabinet 4. The surfaces of the multiple control handles 18 are treated with anti-slip material to facilitate the grip of the operator.

[0031] Specifically, the alarm light 15 on the top of cabinet 1 will light up when the switch cabinet malfunctions, alerting staff. The information board 16 on the front of the outer wall of cabinet 1 is fixed to cabinet 1 by screws 17 connected by threads around the perimeter and is used to display switch cabinet information. The control handle 18 on the front of the outer wall of drawer cabinet 4 has a non-slip surface, making it easy for operators to grip and easily rotate the control handle 18 to control the operation of the equipment inside drawer cabinet 4.

[0032] Reference Figure 1 , Figure 2 and Figure 5 Each of the multiple drawer cabinets 4 has a display screen 19 fixedly connected to the front right side of its outer wall. The surfaces of the multiple display screens 19 are all treated with wear resistance, which can clearly display the equipment's operating parameters and status information for a long time. The surfaces of the multiple rollers 5 are all treated with smoothness, and the spacing between the multiple rollers 5 is equal, which reduces the friction when the drawer cabinets 4 are inserted and removed, ensuring their smooth and stable sliding. At the same time, the uniform spacing ensures balanced force. The front ends of the multiple screws 17 are all provided with cross-shaped grooves 20, which are convenient for tightening or removing with a Phillips screwdriver. The inner walls of the multiple cross-shaped grooves 20 are all treated with wear resistance, which can prevent the cross-shaped grooves 20 from being damaged due to frequent use.

[0033] Specifically, the display screen 19 fixed to the right side of the front end of the outer wall of the drawer cabinet 4 is treated with wear resistance so that it can clearly display the equipment operating parameters and status information for a long time, reducing display problems caused by wear. The rollers 5 have a smooth surface and equal spacing between adjacent rollers, which can reduce the friction when inserting and removing the drawer cabinet 4, ensuring its smooth and stable sliding. At the same time, the uniform spacing ensures balanced force. The screws 17 have a cross groove 20 at the front end and are treated with wear resistance, making it easy to tighten or remove with a Phillips screwdriver. The wear resistance treatment can prevent the cross groove 20 from being damaged due to frequent use, ensuring that the information board 16 is installed firmly.

[0034] Working principle: Multiple drawer slots 3 are provided on the upper and lower sides of the cabinet body 1, providing installation positions for the drawer cabinet 4. Multiple rollers 5 are rotatably connected to the left and right sides of the inner wall of the drawer slots 3, and slide in cooperation with the slide rails 6 on the left and right sides of the outer wall of the drawer cabinet 4. When it is necessary to insert or remove the drawer cabinet 4, the rollers 5 roll in the slide rails 6. Compared with the traditional sliding connection, the friction is greatly reduced. The operator only needs to hold the handles 7 fixedly connected to the left and right sides of the front end of the outer wall of the drawer cabinet 4 to easily push the drawer cabinet 4 to slide in the drawer slots 3. The sliding grooves 8 on the left and right sides of the front end of the outer wall of the drawer cabinet 4 and the push rods 9 slidably connected to them, with the front end of the push rods 9 passing through the handles 7, facilitate the operation. In operation, the insert rod 11, which is slidably connected to the reserved groove 10 at the bottom of the drawer cabinet 4, is slidably connected to the pressing rod 9. The spring 12, which is fixedly connected to the top of the insert rod 11, provides elastic support. When the drawer cabinet 4 is inserted into the drawer groove 3, the pressing rod 9 is released. Under the action of the spring 12, the insert rod 11 is inserted downward into the slots 13 on the left and right sides of the bottom of the inner wall of the drawer groove 3, realizing a stable connection between the drawer cabinet 4 and the cabinet body 1, preventing the drawer cabinet 4 from accidentally sliding out during use. When it is necessary to pull out the drawer cabinet 4 for maintenance or other operations, simply press the pressing rod 9 again to overcome the elastic force of the spring 12, so that the insert rod 11 disengages from the slot 13, and the drawer cabinet 4 can be easily pulled out.

[0035] Furthermore, the rotating sleeve 205 rotatably connected to the top of the hollow tube 201 is threadedly connected to the corresponding threaded rod 202. When the height of the cabinet 1 needs to be adjusted, the rotating sleeve 205 is rotated. Due to the threaded transmission principle, the rotational motion of the rotating sleeve 205 is converted into the vertical linear motion of the threaded rod 202. The foot pad 206 fixedly connected to the bottom end of the threaded rod 202 rises or falls accordingly, thereby fixing and releasing the cabinet 1. The movable wheels 207 fixedly connected to the four corners at the bottom of the cabinet 1 give the cabinet 1 the ability to move as a whole. The movable wheels 207 allow the cabinet 1 to move easily on the ground, making it convenient to move between different positions. Especially when carrying out large-scale maintenance, the cabinet 1 can be moved to a more suitable operating space, reducing the extra physical exertion caused by the limited operation of staff in fixed positions.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
