These grooves 202 engage with the positioning blocks 201 to determine the insertion position of drawer 5. Installation grooves 203 are provided on the upper and lower sides of the inner walls of the two positioning grooves 202 for mounting. Positioning roller assembly 204: The inner walls of multiple mounting slots 203 are rotatably connected to positioning roller assemblies 204. Positioning roller assemblies 204 reduce friction between positioning blocks 201 and positioning slots 202. Positioning roller slots 205 are provided on the upper and lower sides of each positioning block 201. The positioning roller slots 205 cooperate with the positioning roller assembly 204 to guide the insertion of drawer 5. Guide blocks 206 are fixedly connected to the rear sides of each positioning block 201. The guide blocks 206 further guide the accurate insertion of drawer 5. Guide slots 207 are provided on the upper and lower sides of each guide block 206. The guide slots 207 cooperate with the positioning roller assembly 204 to ensure accurate insertion direction of drawer 5. The inner walls of the multiple guide slots 207 are rotatably connected to the outer walls of the corresponding positioning roller assemblies 204 to achieve guidance. In coordination with the rotation, the inner walls of the multiple positioning wheel grooves 205 are rotatably connected to the outer walls of the corresponding positioning wheel assemblies 204, ensuring smooth insertion of drawer 5. The push-pull assembly 6 includes a push-pull handle 602, which facilitates the operator to push and pull drawer 5. The rear side of the push-pull handle 602 is slidably connected to the front side of drawer 5 for easy installation and operation. Two screws 601 are provided on both the left and right ends of the front side of the push-pull handle 602. The screws 601 are used to fix the push-pull handle 602. Multiple washers 603 are provided on the front side of drawer 5 to enhance the stability of the screw 601 connection. The multiple screws 601 all penetrate the push-pull handle 602 and are threaded to the inner walls of the corresponding washers 603, achieving a secure installation of the push-pull handle 602.The protective component 7 includes multiple rubber balls 701. These rubber balls 701 act as a buffer when placing drawer 5 for maintenance, preventing rigid collisions with objects on the ground. The tops of the rubber balls 701 are fixedly connected to the four corners of the bottom of drawer 5, establishing a connection with it. Small ball grooves 702 are provided on the left and right ends of the bottom inner wall of drawer slot 4. These grooves 702 work in conjunction with the rubber balls 701 to assist in positioning drawer 5. The inner walls of the two small ball grooves 702 are slidably connected to the outer walls of the corresponding rubber balls 701, ensuring smooth insertion and removal of drawer 5. The four corners of the bottom of drawer 5... Protective corner protectors 703 are fixedly connected at each point, protecting the corners of the drawer 5 to prevent damage during maintenance and handling. The support assembly 8 includes multiple support legs 801, which support the cabinet body 1. The tops of the support legs 801 are fixedly connected to the four bottom corners of the cabinet body 1, achieving connection with the cabinet body 1. The bottoms of the support legs 801 are all fixedly connected to tapered feet 802, which enhance the grip of the support legs 801 on the ground. The bottoms of the tapered feet 802 are all fixedly connected to rubber pads 803, which increase friction and provide shock absorption.

[0034] Specifically, the operator holds the push-pull handle 602 in the push-pull assembly 6 and tightens the screw 601 to make it pass through the push-pull handle 602 and connect with the washer 603 by thread, thereby firmly installing the push-pull handle 602 on the front side of drawer 5 for easy push-pull operation. During insertion, the operator aligns the guide blocks 206 on both sides of drawer 5 with the positioning grooves 202 on the left and right sides of the inner wall of drawer groove 4 and inserts them. The shape of the guide blocks 206 matches the positioning grooves 202, which itself plays a preliminary alignment and guiding role, ensuring that the drawer can be accurately pushed towards the predetermined position. At the same time, the positioning roller assembly 204 in the mounting grooves 203 on the upper and lower sides of the inner wall of the positioning groove 202 will interact with the guide groove 207 when drawer 5 is inserted. The groove design of the guide groove 207 and the positioning roller assembly 204... With their shapes perfectly matched, during the drawer's advancement, the guide groove 207 guides the rolling direction of the positioning roller assembly 204 through its own shape, enabling it to accurately engage with the positioning roller grooves 205 on the upper and lower sides of the positioning block 201. This precise engagement is not only reflected in the accurate correspondence of positions, but also in the smoothness and stability of the positioning roller assembly 204 as it rolls within the positioning roller grooves 205, reducing friction between the positioning block 201 and the positioning groove 202. When drawer 5 is pulled out for maintenance, the rubber ball 701 at the bottom corner of the drawer acts as a buffer during placement, preventing rigid collisions with the ground. The protective corner 703 protects the drawer's corners, preventing damage from bumps and knocks during transport, and avoiding wear caused by frequent insertion and removal of the slots and blocks, effectively ensuring the reliability of the electrical connection.

[0035] Reference Figure 1 , Figure 3 and Figure 5 The limiting mechanism 3 includes a fixing block 301, which provides an installation base. The bottom of the fixing block 301 is fixedly connected to the top front side of the drawer 5, achieving a stable connection with the drawer 5. The top of the fixing block 301 has a locking groove 302, which provides sliding space for the locking block 303. The locking block 303 is slidably connected to the inner wall of the locking groove 302. The locking block 303, in cooperation with other components, limits the drawer 5. The top of the locking block 303 is fixedly connected to a pull rod 304, which transmits external force to control the movement of the locking block 303. The outer wall of the pull rod 304 is slidably connected to a spring 305, which provides elasticity to the locking block 303, keeping it in the limited position. The top front side of the cabinet 1 has a... The slide 306 provides a moving track for the spring 305 and the locking block 303. The inner wall of the slide 306 is slidably connected to the outer wall of the spring 305 to ensure that the spring 305 moves within a specified path. The top of the pull rod 304 is provided with an unlocking component 307. The unlocking component 307 allows the operator to release the limit on the drawer 5. The unlocking component 307 includes a connecting block 3071, which is used to connect the pull rod 304 and the unlocking pull ring 3072. The bottom of the connecting block 3071 is fixedly connected to the top of the pull rod 304 to achieve a stable connection with the pull rod 304. The top of the connecting block 3071 is rotatably connected to the unlocking pull ring 3072. The operator can move the pull rod 304 by pulling the unlocking pull ring 3072.

[0036] Specifically, the fixing block 301, which is fixed to the front top of drawer 5, moves into the corresponding position on cabinet 1. At this time, the engaging block 303, under the elastic force of the spring 305, partially engages in the sliding groove 306 on the front top of cabinet 1. The bottom of the engaging block 303 slides against the inner wall of the engaging groove 302 on the top of the fixing block 301, thus firmly limiting drawer 5 and preventing it from accidentally sliding out. This ensures the stability of the electrical connection and the reliability of the equipment operation. When drawer 5 needs to be pulled out for maintenance, the operator pulls the unlocking ring 3072 in the unlocking assembly 307. Since the unlocking pull ring 3072 is rotatably connected to the connecting block 3071, when the unlocking pull ring 3072 is pulled, the connecting block 3071 drives the pull rod 304 to move upward. The upward movement of the pull rod 304 compresses the spring 305, causing the locking block 303 to gradually exit from the slide groove 306, releasing the limitation on drawer 5. At this time, the operator can easily pull out drawer 5 through the push-pull assembly 6. After the operation is completed, drawer 5 is reinserted, the spring 305 restores its elasticity, and pushes the locking block 303 to lock into the slide groove 306 again, thus restoring the limitation and fixation of drawer 5.

[0037] Reference Figure 3 , Figure 4 and Figure 5Limiting plates 10 are fixedly connected to the top rear sides of both positioning blocks 201 to limit the insertion position of drawer 5 into cabinet 1, ensuring accurate insertion of drawer 5 and preventing over-insertion. Buffer pads 11 are fixedly connected to the rear sides of both limiting plates 10. The buffer pads 11 act as a buffer when drawer 5 is inserted into cabinet 1, reducing the impact force between the limiting plates 10 and cabinet 1 and protecting the equipment. Limiting grooves 9 are provided on the left and right front ends of cabinet 1, providing sliding tracks for the limiting plates 10 and buffer pads 11 to guide the insertion of drawer 5. In the inward direction, the inner walls of the two limiting grooves 9 are slidably connected to the outer walls of the corresponding limiting plates 10 and buffer pads 11, respectively, to achieve precise positioning and smooth insertion and removal between drawer 5 and cabinet 1. Multiple ventilation holes 12 are equally spaced on the left and right sides of drawer 5. The ventilation holes 12 help the air inside drawer 5 to circulate, assist in heat dissipation, and ensure a good working environment for electrical components inside the drawer. A cooling fan 13 is fixedly connected to the top of the inner wall of cabinet 1. The cooling fan 13 accelerates the air circulation inside cabinet 1, further enhances the heat dissipation effect, and ensures the stable operation of electrical equipment.

[0038] Specifically, the limiting plate 10 is used to limit the position of drawer 5 when it is inserted into cabinet 1, ensuring that drawer 5 is inserted accurately and preventing over-insertion. The buffer pad 11 acts as a buffer when drawer 5 is inserted into cabinet 1, reducing the impact force between the limiting plate 10 and cabinet 1 and protecting the equipment. The limiting groove 9 provides a sliding track for the limiting plate 10 and the buffer pad 11, guiding the insertion direction of drawer 5 and achieving precise positioning and smooth insertion and removal between drawer 5 and cabinet 1. The vent 12 helps the air inside drawer 5 to circulate, assists in heat dissipation, and ensures a good working environment for electrical components inside the drawer. The cooling fan 13 accelerates the air circulation inside cabinet 1 and enhances the heat dissipation effect.

[0039] Working principle: When drawer 5 needs to be inserted into drawer slot 4 of cabinet 1, the operator holds the push-pull handle 602 in the push-pull assembly 6 and screws the screw 601 through it to connect it to the washer 603, thus securing the push-pull handle 602 to the front of drawer 5 for easy push-pull operation. During insertion, the operator aligns the guide blocks 206 on both sides of drawer 5 with the positioning grooves 202 on the left and right sides of the inner wall of drawer slot 4. The shape of the guide blocks 206 matches the positioning grooves 202, which themselves provide initial alignment and guidance, ensuring that the drawer can be accurately pushed towards the predetermined position. At the same time, the positioning roller assembly 204 in the mounting grooves 203 on the upper and lower sides of the inner wall of the positioning groove 202 interacts with the guide groove 207 when drawer 5 is inserted. The groove shape of the guide groove 207 is designed... The design matches the shape of the positioning wheel assembly 204. During the drawer's advancement, the guide groove 207 guides the rolling direction of the positioning wheel assembly 204 through its own shape, enabling it to accurately engage with the positioning wheel grooves 205 on the upper and lower sides of the positioning block 201. This precise engagement is not only reflected in the accurate correspondence of positions, but also in the smoothness and stability of the positioning wheel assembly 204 rolling within the positioning wheel grooves 205. This reduces friction between the positioning block 201 and the positioning groove 202. When drawer 5 is pulled out for maintenance, the rubber ball 701 at the bottom corner of the drawer can act as a buffer when placed, preventing rigid collisions with the ground. The protective corner 703 protects the drawer's corners, preventing damage from bumps and knocks during transport. This avoids wear caused by frequent insertion and removal of the slots and blocks, effectively ensuring the reliability of the electrical connection.

[0040] Furthermore, when drawer 5 is inserted into drawer slot 4 of cabinet 1, the fixing block 301 fixed to the front top of drawer 5 enters the corresponding position of cabinet 1. At this time, the locking block 303, under the elastic force of spring 305, partially engages in the sliding groove 306 on the front top of cabinet 1. The bottom of the locking block 303 slides against the inner wall of the locking groove 302 on the top of the fixing block 301, thus firmly limiting drawer 5 and preventing it from accidentally sliding out, ensuring the stability of the electrical connection and the reliability of equipment operation. When drawer 5 needs to be pulled out for maintenance, the operator pulls the unlocking component 307. The locking ring 3072 is rotatably connected to the connecting block 3071. When the locking ring 3072 is pulled, the connecting block 3071 drives the pull rod 304 to move upward. The upward movement of the pull rod 304 compresses the spring 305, causing the locking block 303 to gradually exit from the slide groove 306, releasing the limitation on drawer 5. At this time, the operator can easily pull out drawer 5 through the push-pull assembly 6. After the operation is completed, drawer 5 is reinserted, the spring 305 restores its elasticity, and pushes the locking block 303 to lock into the slide groove 306 again, thus restoring the limitation and fixation of drawer 5.
