Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical equipment box technology, and in particular to a pull-out mechanism and an electrical equipment box. Background Technology
[0002] The installation and maintenance of components in traditional electrical equipment boxes (such as distribution boxes and control boxes) usually have to be carried out in a narrow box, which is inconvenient and restrictive in terms of operating space. When manually pushing and pulling equipment, uneven force, jamming or deviation can easily occur, affecting stability and component safety. The lack of efficient and smooth electric removal / retraction mechanisms leads to low equipment maintenance efficiency and operational risks. At the same time, the heat dissipation of the box and the design of manual movement need to be optimized.
[0003] Electrical components are fixed inside the enclosure, requiring manual operation within a confined space for maintenance or replacement, which is time-consuming, labor-intensive, and poses safety hazards. Moving the entire device out often relies on simple rails or manual dragging, which is prone to wobbling, shifting, or even jamming, lacking a stable and reliable guiding and driving mechanism. Uneven force and unstable trajectory during the movement of electrical components can easily lead to equipment tilting, loosening of components, or damage. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is to provide a device that facilitates the maintenance of equipment inside an electrical equipment box.
[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a pull-out mechanism, which includes a push-pull component and a fixing component installed inside the box; the push-pull component pushes the fixing component to push the component inside the box out of the box, and the push-pull component pulls the fixing component to pull the component inside the box back into the box.
[0006] In a preferred embodiment of the pull-out mechanism of this utility model: the push-pull assembly is provided in multiple sets, the push-pull assembly includes a motor fixedly connected to the side wall of the box, a threaded rod is installed on one side of the motor, and the other end of the threaded rod is rotatably connected to the inner wall of the box.
[0007] In a preferred embodiment of the pull-out mechanism of this utility model: the threaded rod is threadedly connected to a threaded plate, the threaded plate has a hole, a slide rod is slidably connected in the hole of the threaded plate, and the two ends of the slide rod are fixedly connected to the inner wall of the box.
[0008] In a preferred embodiment of the pull-out mechanism of this utility model: a first drive rod is hinged to one side of the threaded plate, and a fixed plate is hinged to the other end of the first drive rod.
[0009] In a preferred embodiment of the pull-out mechanism of this utility model: a second drive rod is hinged to the inner wall of the box, and a drive block is hinged to the second drive rod. The middle parts of the first drive rod and the second drive rod are hinged to each other through a rotating shaft.
[0010] In a preferred embodiment of the pull-out mechanism of this utility model: a support rod is fixedly connected to one side of the fixed plate, and the support rod is located on the side of the fixed plate near the threaded rod.
[0011] In a preferred embodiment of the pull-out mechanism of this utility model: the driving block slides on the outer wall of the support rod.
[0012] In a preferred embodiment of the pull-out mechanism of this utility model: the fixing component includes the fixing plate, and a plurality of mounting plates are fixed on the side of the fixing plate away from the threaded rod.
[0013] In a preferred embodiment of the electrical equipment box of this utility model: a sliding groove is provided on the inner side wall of the box body, and a sliding strip is fixed on the side of the mounting plate near the sliding groove, and the sliding strip slides in the sliding groove.
[0014] The above-mentioned technical problems are also solved by the following technical solution: a handle is fixedly connected to the box body, and ventilation holes are provided on both sides of the box body.
[0015] The beneficial effects of this utility model are as follows: the displacement of the threaded plate is precisely controlled by the motor-driven threaded rod, and the rigid limiting of the threaded plate by the double sliding rod eliminates the risk of jamming during the push-pull action. The first drive rod and the second drive rod form a cross linkage structure through the central rotating shaft. With the adaptive sliding of the drive block on the support rod, the fixed plate bears a bidirectional balanced thrust. The mechanical optimization of the cross drive rod ensures that the equipment is not tilted when it is moved out. Multiple mounting plates are distributed to bear the load. The mounting plates form a full-stroke linear guide through the precise fitting of the sliding strip and the box groove, which effectively suppresses the shaking during the movement of electrical components. The double push-pull components are symmetrically distributed on both sides of the fixed components, applying a uniform linear driving force to the fixed plate and avoiding trajectory deviation caused by single-point force.

[0022] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.
[0024] Reference Figure 1 This embodiment provides a pull-out mechanism and an electrical equipment box, including a push-pull component 2 and a fixing component 3 installed inside the box body 1; the push-pull component 2 pushes the fixing component 3 to push the components inside the box body 1 out of the box body 1, and the push-pull component 2 pulls the fixing component 3 to pull the components inside the box body 1 back into the box body 1.
[0025] Furthermore, the push-pull assembly 2 is provided in multiple sets. The push-pull assembly 2 includes a motor fixedly connected to the side wall of the housing 1. A threaded rod 22 is installed on one side of the motor. The other end of the threaded rod 22 is rotatably connected to the inner wall of the housing 1. The threaded rod 22 is threadedly connected to a threaded plate 23. A hole is opened on the threaded plate 23. A slide rod 29 is slidably connected in the hole of the threaded plate 23. Both ends of the slide rod 29 are fixedly connected to the inner wall of the housing 1.
[0026] Multiple sets of push-pull components 2 are evenly distributed on the fixed components 3 to ensure that the push-pull components 2 apply uniform force to the fixed components 3. The motor is fixed on the housing 1. When the motor is driven, it drives the threaded rod 22 installed on one side to rotate. The threaded rod 22 is screwed with a threaded plate 23. When the threaded rod 22 rotates, it drives the threaded plate 23 to move. There are two sliding rods 29 on the threaded plate 23, located at both ends of the threaded plate 23. The sliding rods 29 limit the threaded plate 23 so that the rotation of the threaded rod 22 can drive the threaded plate 23 to move horizontally.
[0027] Furthermore, a first drive rod 24 is hinged to one side of the threaded plate 23, and a fixed plate 33 is hinged to the other end of the first drive rod 24.
[0028] When the threaded plate 23 moves, the first drive rod 24, which is hinged to the threaded plate 23, rotates because the first drive rod 24 is of fixed length. The first drive rod 24 and the fixed plate 33 can only rotate relative to each other, thereby pushing the fixed plate 33.
[0029] Furthermore, a second drive rod 25 is hinged to the inner wall of the housing 1, and a drive block 28 is hinged to the second drive rod 25. The middle parts of the first drive rod 24 and the second drive rod 25 are hinged to each other through a pivot. A support rod 27 is fixedly connected to one side of the fixed plate 33. The support rod 27 is located on the side of the fixed plate 33 near the threaded rod 22, and the drive block 28 slides on the outer wall of the support rod 27.
[0030] The support rod 27 is fixed to the fixed plate 33. One end of the second drive rod 25 is connected to the support rod 27 through the drive block 28, and the drive block 28 slides on the support rod 27. The second drive rod 25 is hinged to the drive block 28, and the other end of the second drive rod 25 is hinged to the housing 1. When the fixed plate 33 moves, it drives the support rod 27 to move. The second drive rod 25 has a fixed length. When the support rod 27 moves, it drives the drive block 28 to slide on the support rod 27. The second drive rod 25 and the first drive rod 24 form a cross structure. During the movement of the fixed plate 33, the second drive rod 25 provides dynamic and stable support for the first drive rod 24 to push the fixed plate 33 through the sliding cooperation between the drive block 28 and the support rod 27.
[0031] Specifically, the fixing component 3 includes a fixing plate 33. Multiple mounting plates 32 are fixed on the side of the fixing plate 33 away from the threaded rod 22. A sliding groove 13 is provided on the inner side wall of the housing 1. A sliding strip 31 is fixed on the side of the mounting plate 32 near the sliding groove 13. The sliding strip 31 slides in the sliding groove 13.
[0032] Among them, a number of mounting plates 32 are fixedly connected to the side of the fixed plate 33 facing the door of the box body 1. The inner sidewall of the box body 1 is symmetrically provided with longitudinal sliding grooves 13. Each mounting plate 32 is fixed with a corresponding sliding strip 31, which slides in the sliding groove 13. Through the sliding cooperation between the sliding strip 31 and the sliding groove 13, the movement trajectory of the mounting plate 32 is further constrained to ensure that it remains stable during the pushing and pulling process.
[0033] Furthermore, a handle 11 is fixedly connected to the box body 1, and ventilation holes 12 are provided on both sides of the box body 1.
[0034] The motor rotates, causing the threaded rod 22 to rotate. The rotation of the threaded rod 22 causes the threaded plate 23 to move. The threaded plate 23 pushes the first drive rod 24 to move. One end of the first drive rod 24 pushes the fixed plate 33 to move. The fixed plate 33 drives the support rod 27 to move, causing the drive block 28 to slide along the outer surface of the support rod 27. Through the cooperation of the first drive rod 24 and the second drive rod 25, the electrical equipment on the mounting plate 32 can be quickly and conveniently moved to the outside of the housing 1. The motor rotates in the opposite direction to move the electrical equipment on the mounting plate 32 to the inside of the housing 1.
[0035] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
