[0002] In the field of electrical equipment installation and maintenance, distribution boxes, as centralized installation carriers for electrical components, directly affect the efficiency of equipment operation and maintenance due to the convenience and safety of their internal maintenance. Traditional distribution box mounting frames often use fixed connections, directly welded to the box body or secured with bolts, making it impossible to adjust their position according to maintenance needs. During maintenance, some components obstruct each other, making it difficult for operators to reach the parts to be inspected, significantly increasing the difficulty of operation. Therefore, this utility model proposes a large-space maintenance distribution box with a movable mounting frame to solve the above problems. Utility Model Content

[0014] 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.

[0015] Example: like Figure 1-8 As shown, this embodiment proposes a large-space maintenance distribution box with a movable mounting frame, including a box body 10, wherein a mounting frame 20 for installing electrical components is provided inside the box body 10. The housing 10 is symmetrically provided with two sets of side plates 11, and two sets of guide plates 30 are provided on the side plates 11. Guide blocks 50 are provided on the guide plates 30. The guide blocks 50 are connected to the side end of the mounting frame 20. The housing 10 is also provided with a drive fixing assembly 40. The drive fixing assembly 40 cooperates with the mounting frame 20 to allow the mounting frame 20 to move on the guide plates 30 to adjust the maintenance position.

[0016] In this embodiment, when the electrical components inside the distribution box are inspected and repaired, the mounting frame 20 is moved by the drive fixing component 40. With the cooperation of the guide block 50 and the guide plate 30, the mounting frame 20 is moved along the direction of the guide plate 30 to adjust the inspection position. When the mounting frame 20 is adjusted to a suitable position, the position of the mounting frame 20 is positioned by the drive fixing component 40. After the inspection and repair is completed, the mounting frame 20 is reset by the drive fixing component 40. Through the cooperative design of the drive fixing component 40 and the mounting bracket 20, the mounting bracket 20 can be driven to move flexibly along the guide plate 30, so as to adjust the maintenance position as needed. This effectively solves the technical problems of limited maintenance space and inconvenient operation inside the traditional distribution box, and significantly improves the convenience and accessibility of electrical component maintenance. The matching connection structure between the guide plate 30 and the guide block 50 provides precise guidance for the displacement of the mounting frame 20, ensuring the stability and positional accuracy of the mounting frame 20 during the adjustment process, avoiding deviation, jamming and other situations during the displacement process, and improving the safety and reliability of maintenance operations. The drive fixing component 40 integrates both drive and positioning functions. It can not only drive the mounting bracket 20 to adjust its displacement, but also achieve reliable positioning after the maintenance position is determined. No additional positioning mechanism is required, which simplifies the overall structural design and shortens the operation time for maintenance preparation and reset, thereby improving maintenance efficiency.

[0017] Specifically, the mounting frame 20 includes two sets of vertical mounting plates 22, which are symmetrically arranged, and two sets of horizontal mounting plates 21 are arranged between the two sets of vertical mounting plates 22; The guide block 50 is connected to the vertical mounting plate 22, and the drive fixing component 40 cooperates with the vertical mounting plate 22.

[0018] In this embodiment, two sets of symmetrically arranged vertical mounting plates 22 and two sets of horizontal mounting plates 21 constitute the main body of the frame mounting bracket 20. Through the synergistic effect of vertical support and horizontal connection, the weight load of electrical components is effectively distributed, avoiding deformation or damage caused by concentrated force on a single plate. This significantly improves the structural strength and load-bearing stability of the mounting bracket 20, and can stably adapt to the installation requirements of electrical components of different specifications and weights, ensuring the structural reliability of the components during long-term operation.

[0019] Specifically, the guide plate 30 is provided with a T-shaped groove 31, and the guide block 50 is provided with a T-shaped block 52. The T-shaped block 52 is adapted to the T-shaped groove 31 and is slidably disposed in the T-shaped groove 31.

[0020] In this embodiment, through the adaptive sliding structure of T-block 52 and T-slot 31, the narrow opening and wide cavity of T-slot 31 can radially limit T-block 52, effectively restricting the tendency of T-block 52 to detach along the perpendicular sliding direction. This avoids the technical risk of mounting bracket 20 falling off due to the failure of the connection between guide block 50 and guide plate 30 when adjusting displacement or bearing the weight of electrical components. It significantly improves the structural reliability of the guiding fit and ensures the safety of equipment and personnel during maintenance operations.

[0021] Specifically, a guide fixing hole 32 is provided in the T-slot 31, and the guide fixing hole 32 is connected to the side plate 11 by bolts.

[0022] In this embodiment, by opening a guide fixing hole 32 in the T-slot 31 and using bolts to connect it to the side plate 11, the guide plate 30 and the side plate 11 form a detachable rigid fixing structure, which effectively prevents the guide plate 30 from loosening or shifting when bearing the load of the mounting frame 20 and electrical components, ensuring that the guide plate 30 always maintains the preset installation posture, and provides a reliable foundation support for the smooth sliding of the mounting frame 20. This solves the technical problem that traditional welding or snap-fit ​​connections are prone to loosening due to vibration and are difficult to repair.

[0023] Specifically, the vertical mounting plate 22 is provided with mounting and fixing holes 23; The guide block 50 is also provided with a guide connection hole 51, which is connected to the mounting and fixing hole 23 by bolts.

[0024] In this embodiment, by precisely aligning the mounting fixing hole 23 with the guide connection hole 51 and rigidly tightening the bolts, the guide block 50 and the vertical mounting plate 22 form a detachable rigid connection structure, effectively eliminating the assembly gap between the two. This avoids the problem of relative displacement, loosening, or even separation between the guide block 50 and the vertical mounting plate 22 when the mounting frame 20 is bearing the load of electrical components, sliding along the guide plate 30, or vibrating the equipment. It ensures that the guide block 50 always stably transmits the guiding constraint effect, providing a reliable connection foundation for the smooth sliding and position adjustment of the mounting frame 20. This solves the technical defects of traditional snap-fit ​​or welded connections that are prone to failure due to vibration and difficult to disassemble and maintain.

[0025] Specifically, the drive fixing assembly 40 includes a drive screw 42, which is rotatably mounted on the housing 10, and an actuating ring 41 is provided on the outer wall of the drive screw 42; The outer wall of the drive screw 42 is provided with a threaded sleeve 43, which is threadedly engaged with the drive screw 42 and connected to the vertical mounting plate 22.

[0026] In this embodiment, the threaded engagement structure of the drive screw 42 and the threaded sleeve 43 constitutes a linear transmission mechanism. The rotational motion of the drive screw 42 can be converted into the linear motion of the threaded sleeve 43, thereby driving the vertical mounting plate 22 connected thereto to move smoothly in a preset direction. Since the threaded drive has a fixed pitch accuracy, the displacement of the mounting bracket 20 can be precisely controlled by controlling the rotation angle of the drive screw 42, avoiding problems such as excessive displacement and positioning deviation that exist in traditional manual push-pull adjustment, ensuring that the mounting bracket 20 can accurately stop at the required maintenance position, and significantly improving the convenience and accuracy of maintenance operations. Based on the self-locking principle of threaded transmission, when the drive screw 42 stops rotating, the threaded sleeve 43 and the drive screw 42 can automatically form a self-locking constraint, preventing the threaded sleeve 43 from sliding under the gravity load of the mounting bracket 20 and electrical components or the vibration of the equipment, thereby achieving stable positioning of the mounting bracket 20 in the maintenance position. This design eliminates the need for additional positioning and locking mechanisms such as buckles and bolts, simplifying the overall structure of the drive fixing component 40, reducing the number of parts, lowering equipment manufacturing costs and assembly complexity, and avoiding the positioning risk caused by the failure of additional locking mechanisms.

[0027] Specifically, the vertical mounting plate 22 is provided with a reinforcing connecting plate 24, and the reinforcing connecting plate 24 is provided with a reinforcing connecting hole 25; The threaded sleeve 43 is provided with a drive connecting plate 44, and the drive connecting plate 44 is provided with a drive connecting hole 45. The drive connecting hole 45 is matched with the reinforcement connecting hole 25, and the drive connecting hole 45 and the reinforcement connecting hole 25 are connected by bolts.

[0028] In this embodiment, by fitting the reinforcing connecting plate 24 and the driving connecting plate 44 together and by rigidly fastening the bolts, the contact area between the two is significantly increased compared to the direct connection between the threaded sleeve 43 and the vertical mounting plate 22. This allows the driving force transmitted by the driving fixing assembly 40 to be evenly distributed to the contact area between the reinforcing connecting plate 24 and the vertical mounting plate 22, avoiding structural damage such as deformation or cracking of the vertical mounting plate 22 or the threaded sleeve 43 due to localized stress concentration. This ensures the reliability of the driving load transmission and solves the technical defect of the traditional direct connection method, which is prone to failure due to the small contact area.
