Description

Technical Field

[0001] This utility model relates to the field of intelligent low-voltage equipment installation technology, and in particular to a low-voltage control box mounting bracket. Background Technology

[0002] In the field of intelligent low-voltage electrical systems, the installation of low-voltage control boxes often relies on mounting brackets for fixation. Chinese Patent 202422474413.5 discloses a portable intelligent low-voltage control box mounting bracket, the core structure of which includes two main frames. The front of the main frame is equipped with a telescopic mechanism consisting of two telescopic frames. The upper and lower parts of the telescopic frames are equipped with rails. Positioning holes are opened at the outer ends of the front and rear parts of the telescopic frames and the main frame. A positioning groove is opened at the center of the front and rear parts of the two. A hoop groove is also provided at the inner end of the front part of the telescopic frame.

[0003] However, in actual operation, it is necessary to first unfold the two main frames and fix them with matching bolts. Then, fix the whole to the mounting surface (such as a wall), adjust the extension length of the telescopic frame inside the main frame, and finally fix it to the mounting surface by inserting bolts through the positioning holes.

[0004] However, this installation method also has certain operational drawbacks and safety hazards: when workers use tools such as electric drills and wrenches to insert bolts into the positioning holes and fix them to the wall, the telescopic frame relies solely on sliding connection with the main frame and lacks a temporary limiting structure. Therefore, another hand must continuously apply pushing or pulling force to the telescopic frame to maintain its position. This makes single-person operation difficult, as uneven force on the hand can easily cause bolt misalignment, affecting installation accuracy. It also increases the risk of tools slipping or hand injuries during operation. While two-person operation can alleviate this problem, it increases labor costs and reduces installation efficiency. Therefore, a low-voltage control box mounting bracket is proposed to solve these problems. Utility Model Content

[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a mounting bracket for a low-voltage control box. By setting a limiting component, after adjusting the positions of the mounting panel and the second fixed panel, the abutment block can be driven to abut against the abutment plate by rotating the threaded knob, thereby temporarily locking the positions of the two. This eliminates the need for continuous manual support by workers, saving labor costs and improving installation efficiency.

[0006] (II) Technical Solution This utility model provides a mounting bracket for a low-voltage control box, including a central base. A first fixing panel is fixedly mounted on the back of the central base. The first fixing panel has first fixing holes through its upper and lower ends. Rocker arms are hinged to both sides of the central base. A sliding component is mounted in the middle of the rocker arm. One end of the sliding component is fixedly connected to the mounting panel, and the other end is fixedly connected to a second fixing panel. The mounting panel and the second fixing panel are locked in position by a limiting component. A stop plate that cooperates with the limiting component is fixedly mounted on the upper end of the rocker arm. Connectors are provided on both the upper and lower sides of the second fixing panel. The connection between the central base and the rocker arm is unlocked and fixed by an insertion component. The mounting panel has multiple evenly spaced low-voltage control box mounting holes.

[0007] Furthermore, the limiting component includes a connecting plate, a threaded knob, a threaded sleeve, and a stop block. The connecting plate is fixedly installed above the mounting panel and the second fixed panel. The threaded sleeve extends vertically through and is fixed to the middle of the connecting plate. The middle of the threaded knob passes through the threaded sleeve through a threaded structure, and its end is connected to the stop block. The stop block and the stop plate form an adjustable abutment fit.

[0008] Furthermore, the sliding assembly includes a limiting slide groove and a connecting slide plate. The limiting slide groove is laterally opened through the rocker arm. The middle part of the connecting slide plate slidably passes through the rocker arm through the limiting slide groove. One end of the connecting slide plate is fixedly connected to the mounting panel, and the other end of the connecting slide plate is fixedly connected to the second fixed panel.

[0009] Furthermore, the connector includes a side plate and a second fixing hole. The upper and lower sides of the second fixing panel are respectively vertically fixed to the side plate, and the second fixing hole is opened through the middle of the side plate.

[0010] Furthermore, the position of the second fixing hole is further away from the central axis of the first fixing panel than the position of the first fixing hole.

[0011] Furthermore, the insertion assembly includes a first insertion hole, a second insertion hole, and a pin. The first insertion hole is vertically inserted at one end of the rocker arm facing the central base. The second insertion hole is vertically inserted on both sides of the central base and corresponds to and matches the first insertion holes on both sides. The pin has an L-shaped structure and can be inserted into the second insertion hole and the first insertion hole from top to bottom.

[0012] Furthermore, when the rocker arm is in the folded state, the gap between the outer edge of the first insertion hole and the outer edge of the central base is 2-3 mm.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This invention relates to a low-voltage control box mounting bracket. By setting a limiting component, after the positions of the mounting panel and the second fixed panel are adjusted, the abutment block and the abutment plate can be temporarily locked by rotating the threaded knob. This eliminates the need for continuous hand support, effectively reducing the difficulty of single-person operation, avoiding bolt alignment deviations caused by uneven hand force, improving installation accuracy, and reducing the risk of tool slippage or hand injury. It also eliminates the need for two-person operation, saving labor costs and improving installation efficiency. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: like Figure 1-4 As shown, the present invention proposes a mounting bracket for a low-voltage control box, including a central base 10. A first fixing panel 6 is fixedly installed on the back of the central base 10. The first fixing panel 6 has first fixing holes 5 through both the upper and lower ends. Both sides of the central base 10 are connected to rocker arms 13 by hinges. A sliding component is assembled in the middle of the rocker arm 13. One end of the sliding component is fixedly connected to the mounting panel 11, and the other end of the sliding component is fixedly connected to the second fixing panel 17. The mounting panel 11 and the second fixing panel 17 are locked in position by a limiting component. A stop plate 2 that cooperates with the limiting component is fixedly installed on the upper end face of the rocker arm 13. Connectors are provided on both the upper and lower sides of the second fixing panel 17. The connection between the central base 10 and the rocker arm 13 is unlocked and fixed by an insertion component. The mounting panel 11 has a plurality of evenly spaced low-voltage control box mounting holes 12.

[0023] It should be noted that the central base 10 serves as a load-bearing structure, and the unfolding angle is adjusted by the rocker arm 13 connected by a hinge.

[0024] When the mounting panels 11 on both sides are folded, the gap between them is 0-8mm.

[0025] In this embodiment, the limiting component includes a connecting plate 3, a threaded knob 4, a threaded sleeve 15, and a stop block 14. The connecting plate 3 is fixedly installed at the upper position between the mounting panel 11 and the second fixed panel 17. The threaded sleeve 15 is vertically inserted and fixed in the middle of the connecting plate 3. The middle part of the threaded knob 4 passes through the threaded sleeve 15 through the threaded structure and its end is connected to the stop block 14. The stop block 14 and the stop plate 2 form an adjustable abutment fit.

[0026] It should be noted that the connecting plate 3 provides a stable installation reference for the limit component. The threaded engagement between the threaded sleeve 15 and the threaded knob 4 can convert the rotational motion into linear motion, thereby realizing the lifting and lowering of the stop block 14. The abutment and locking between the stop block 14 and the stop plate 2 does not require additional tools and can be operated with one hand, which improves the convenience of operation.

[0027] In this embodiment, the sliding assembly includes a limiting slide groove 1 and a connecting slide plate 16. The limiting slide groove 1 is opened horizontally through the rocker arm 13. The middle part of the connecting slide plate 16 is slidably passed through the rocker arm 13 through the limiting slide groove 1. One end of the connecting slide plate 16 is fixedly connected to the mounting panel 11, and the other end of the connecting slide plate 16 is fixedly connected to the second fixed panel 17.

[0028] It should be noted that the limiting groove 1 constrains the sliding trajectory of the connecting sliding plate 16, preventing it from shifting or shaking during movement.

[0029] In this embodiment, the connector includes a side plate 8 and a second fixing hole 9. The upper and lower sides of the second fixing panel 17 are respectively vertically fixed to the side plate 8, and the second fixing hole 9 is opened through the middle of the side plate 8.

[0030] It should be noted that the second fixing panel 17 is further fixed to the mounting surface by using bolts or other fasteners through the second fixing holes 9 on the side plates 8 on both sides of the second fixing panel 17, thus completing the entire installation process.

[0031] In this embodiment, the position of the second fixing hole 9 is further away from the central axis of the first fixing panel 6 than the position of the first fixing hole 5.

[0032] It should be noted that the first fixing hole 5 and the second fixing hole 9 are staggered, which expands the range of fixing support.

[0033] Example 2: like Figure 1-3 As shown, the insertion assembly includes a first insertion hole 18, a second insertion hole 19, and a pin 7. The first insertion hole 18 is vertically opened through one end of the rocker arm 13 facing the central base 10. The second insertion hole 19 is vertically opened through both sides of the central base 10 and corresponds to the first insertion holes 18 on both sides. The pin 7 has an L-shaped structure and can be inserted into the second insertion hole 19 and the first insertion hole 18 from top to bottom.

[0034] It should be noted that the corresponding fit between the first socket 18 and the second socket 19 ensures the limiting accuracy of the pin 7 after insertion. The L-shaped pin 7 is not only easy to hold and insert, but also forms a natural anti-dislodgement after insertion, ensuring the reliability of the rocker arm 13.

[0035] In this embodiment, when the rocker arm 13 is in the folded state, the gap between the outer edge of the first insertion hole 18 and the outer edge of the middle base 10 is 2-3mm.

[0036] It should be noted that a gap of 2-3mm will not be too small, which would cause frictional interference between the rocker arm 13 and the central base 10 when folding, thus affecting the smoothness of folding; nor will a gap that is too large cause the rocker arm 13 to rotate excessively when folded.

[0037] Working principle: In use, the first fixing panel 6 is first fixed to the mounting surface using bolts or other fasteners through the first fixing hole 5 on the first fixing panel 6, and the pin 7 is pulled out. At this time, the limiting effect between the rocker arm 13 and the base 10 is canceled. Then, according to the actual use needs, the mounting panel 11 and the second fixing panel 17 are pushed or pulled, so that the connecting sliding plate 16 slides along the limiting sliding groove 1 on the rocker arm 13. After adjusting it to a suitable position, the threaded knob 4 on the connecting plate 3 is rotated. Under the action of the threaded sleeve 15, the threaded knob 4 drives the abutment 1. 4. Move downwards until the stop block 14 and the stop plate 2 on the rocker arm 13 are tightly abutted, thereby temporarily locking the mounting panel 11 and the second fixed panel 17 in place without the need for continuous hand support by the operator. Then, unfold the rocker arm 13 and insert the pin 7 into the second insertion hole 19 and the first insertion hole 18, thereby limiting the position of the pin 7 when it is unfolded. When the rocker arm 13 is unfolded, the second fixed panel 17 is further fixed to the mounting surface by bolts and other fasteners through the second fixing holes 9 on the side plates 8 on both sides of the second fixed panel 17, thus completing the entire installation process.

[0038] Finally, the low-voltage control box is installed through the low-voltage control box mounting hole 12 on the mounting panel 11, and the second fixing panel 17 is further fixed to the mounting surface by bolts and other fasteners through the second fixing holes 9 on the side plates 8 on both sides of the second fixing panel 17.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
