[0002] Low-voltage switchgear typically contains components such as circuit breakers, contactors, thermal relays, and disconnect switches. These components work together to ensure the stable operation of the power system and provide necessary protection against damage caused by overload or short circuit.

[0003] Chinese Patent Publication No. CN216354928U, published on April 19, 2022, discloses a blind-plug communication device for a drawer unit of a low-voltage switchgear, belonging to the field of electrical equipment technology. The structure of this utility model includes a blind-plug socket installed in the drawer cabinet. The blind-plug socket consists of a moving blind-plug socket and a stationary blind-plug socket. The moving blind-plug socket is provided with a guide rod, and the stationary blind-plug socket is provided with a guide hole that cooperates with the guide rod. Both the moving and stationary blind-plug sockets have square-mouth slots in their middle sections.

[0004] The existing guide components for low-pressure drawer opening mechanisms, such as those mentioned above, are mostly common slider and slide rail structures. In actual implementation, when the drawer is opened significantly, the contact area between the slider and the rail is small, and the weight of the drawer is concentrated in a small area of ​​the rail. Over time, the rail is prone to deformation. Therefore, there is an urgent need to propose corresponding guide components for low-pressure drawer opening mechanisms to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a guide component for low-pressure cabinet drawers in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A guide assembly for a low-pressure drawer includes a backing frame and a slider fixedly connected to the drawer. The inner wall of the backing frame is fixedly connected to a slide rail that slides with the slider. A side seat is fixedly connected to the front end of the slide rail. A slide plate is fixedly connected to the inner wall of the side seat. A card seat and a fixing assembly for switching the horizontal position of the card seat are integrated on the outer side of the slide plate.

[0008] Preferably, a locking rod is provided inside the slide rail, the outer wall of the locking rod is screwed to the inner wall of the liner, and a rubber pad is interference-fitted inside the slide rail, with the inner wall of the rubber pad abutting against the outer wall of the locking rod.

[0009] Preferably, ball bearings are rotatably connected to the inner surface of both sides of the vertical end of the slide rail.

[0010] Preferably, the fixing component includes a sliding sleeve fixedly connected to the card seat, the inner surface of the sliding sleeve being slidably connected to the outer surface of the slide plate, and a fastening rod being screwed onto the outer surface of the sliding sleeve, with the open end of the fastening rod abutting against the outer surface of the slide plate.

[0011] Preferably, two sets of limiting plates are fixedly connected to the outer wall of the side seat, and the two sets of limiting plates are distributed on both sides of the horizontal end of the sliding sleeve.

[0012] Preferably, a positioning rod is screwed onto the inner surface of the card holder.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, pushing the drawer component causes the slider to slide along the slide rail, thereby enabling the connector on the drawer component to accurately connect with the socket inside the cabinet, thus guiding the drawer component. When the drawer component is opened to a large extent, the movable sleeve can slide along the slide plate until the card seat is fully engaged with the outer part of the slider. The fastening rod completes the fixation of the sleeve and the card seat. The card seat provides partial support and positioning for the slider, thereby preventing the weight of the drawer component from being fully applied to a small area of ​​the slide rail, thus effectively preventing deformation of the rail. Even after the drawer component is fully integrated with the cabinet, the drawer can be stably closed by moving the card seat to the front of the drawer component.

[0015] 2. In this application, the locking rod is used to fix the slide rail and the liner frame, which is convenient to disassemble and assemble. The rubber pad is inserted into the slide rail and the interference fit ensures the stability of the rubber pad. The rubber pad isolates and protects the locking rod while avoiding contact friction between the locking rod and the slider. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] The guide assembly for low-pressure drawer opening includes a frame 1 and a slider 2 fixedly connected to the drawer. The inner wall of the frame 1 is fixedly connected to a slide rail 3 that slides with the slider 2. The front end of the slide rail 3 is fixedly connected to a side seat 4. The inner wall of the side seat 4 is fixedly connected to a slide plate 9. The outer side of the slide plate 9 integrates a card seat 7 and a fixing assembly for switching the horizontal position of the card seat 7.

[0025] Pushing the drawer assembly causes the slider 2 to slide along the slide rail 3, allowing the connector on the drawer assembly to accurately connect with the socket inside the cabinet, thus guiding the drawer assembly. When the drawer assembly is opened to a large extent, the movable sleeve 10 can slide along the slide plate 9 until the bracket 7 is fitted onto the outer part of the slider 2. The sleeve 10 and the bracket 7 are then fixed by the fastening rod 11. The bracket 7 provides partial support and positioning for the slider 2, thus preventing the weight of the drawer assembly from being entirely applied to a small area of ​​the slide rail 3, effectively preventing deformation of the slide rail 3. Even after the drawer assembly is fully integrated with the cabinet, the bracket 7 can be moved to the front of the drawer assembly to achieve stable closing of the drawer.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, a locking rod 6 is inserted inside the slide rail 3. The outer wall of the locking rod 6 is screwed to the inner wall of the liner 1. A rubber pad 5 is interference-fitted inside the slide rail 3, and the inner wall of the rubber pad 5 abuts against the outer wall of the locking rod 6. The locking rod 6 is used to fix the slide rail 3 and ensures the ease of disassembly and assembly of the liner 1. When the rubber pad 5 is inserted into the slide rail 3, the interference fit ensures the stability of the rubber pad 5. The rubber pad 5 isolates and protects the locking rod 6 while preventing contact friction between the locking rod 6 and the slider 2.

[0027] Specifically, such as Figure 2 and Figure 3As shown, ball bearings are rotatably connected to the inner walls of both sides of the vertical end of the slide rail 3 to ensure the stability of the sliding engagement between the slide rail 3 and the slider 2. The fixing component includes a sliding sleeve 10 fixedly connected to the card holder 7. The inner wall of the sliding sleeve 10 is slidably connected to the outer wall of the slide plate 9. A fastening rod 11 is screwed onto the outer wall of the sliding sleeve 10, and the open end of the fastening rod 11 abuts against the outer wall of the slide plate 9. The sliding sleeve 10 is moved to slide along the slide plate 9 until the card holder 7 is fitted onto the outer part of the slider 2. The fixing of the sliding sleeve 10 and the card holder 7 is completed by the fastening rod 11. Two sets of limiting plates 12 are fixedly connected to the outer wall of the side seat 4, and the two sets of limiting plates 12 are distributed on both sides of the horizontal end of the sliding sleeve 10 to limit the extreme positions of the sliding sleeve 10 on both sides of the horizontal end. A positioning rod 8 is screwed onto the inner wall of the card holder 7. The positioning rod 8 is rotated so that its open end abuts against the outer wall of the slider 2. The contact friction between the open end of the positioning rod 8 and the slider 2 further ensures the stability of the contact between the card holder 7 and the slider 2.

[0028] Working principle: Pushing the drawer component causes the slider 2 to slide along the slide rail 3, allowing the connector on the drawer component to accurately connect with the socket inside the cabinet, thus guiding the drawer component. When the drawer component is opened to a large extent, the movable sleeve 10 slides along the slide plate 9 until the bracket 7 is fitted onto the outer part of the slider 2. The sleeve 10 and the bracket 7 are then fixed by the fastening rod 11. The bracket 7 provides partial support and positioning for the slider 2, thus preventing the weight of the drawer component from being entirely applied to a small area of ​​the slide rail 3, effectively preventing deformation of the slide rail 3. Even after the drawer component is fully integrated with the cabinet, the bracket 7 can be moved to the front of the drawer component to achieve stable closing of the drawer. The locking rod 6 ensures the ease of disassembly and assembly of the slide rail 3 and the frame 1. The rubber pad 5 is inserted into the slide rail 3, and the interference fit ensures the stability of the rubber pad 5. The rubber pad 5 isolates and protects the locking rod 6 while preventing contact friction between the locking rod 6 and the slider 2.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
