[0003] Patent document CN107658698B discloses a method for assembling a distribution cabinet frame. The distribution cabinet frame includes frame profiles and connectors. The frame profiles consist of a first profile and a second profile, both of which are hollow rectangular tubes. The second profile is fitted inside the hollow rectangular tube of the first profile, allowing it to move along the length of the first profile within the hollow rectangular tube to form a telescopic structure. A fixing device is provided between the first and second profiles to fix the length of the frame profiles. The frame profiles and connectors are detachably connected. The distribution cabinet frame assembled in this way has good structural strength, easy dimensional control, and unrestricted expansion direction of the cabinet.

[0004] However, in the process of implementing the above technical solution, the following technical problems were found:

[0005] In this method of assembling a distribution cabinet frame, the distribution cabinet is formed by a scalable frame, which can support the expansion of the distribution cabinet. However, for the expanded distribution cabinet, it is difficult to use the existing structure to complete the assembly work after the change of the distribution cabinet when it is assembled and fixed to the wall, support or plate. Utility Model Content

[0006] To overcome the shortcomings of existing distribution cabinet frame assembly methods, where the external assembly and fixing of the distribution cabinet to the wall, support, or plate is difficult to complete using the existing structure after the change of the distribution cabinet, this application provides an adjustable distribution cabinet frame. By having the second connecting strip fastened to the outside of the guide rod on the two horizontal sides of the two L-shaped corner brackets via a movable slot, and the first connecting strip fastened to the outside of the guide rod on the two vertical sides of the two L-shaped corner brackets via a movable slot, the guide rods slide inside the movable slot to adjust the distance between the two L-shaped corner brackets, realizing the scaling function of the four L-shaped corner brackets, which is convenient to adapt to the state of the distribution cabinet after the size and space are adjusted according to the existing technology.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] An adjustable power distribution cabinet frame includes a first connecting strip, a second connecting strip, an L-shaped corner bracket, and a power distribution cabinet. There are two first connecting strips, which are arranged symmetrically on the left and right sides.

[0009] There are two second connecting strips, arranged symmetrically vertically.

[0010] There are four L-shaped corner brackets;

[0011] All four L-shaped corner brackets are L-shaped and are located at one end of the second connecting strip and the first connecting strip, respectively. Positioning slots are provided in the middle of the two first connecting strips and the two second connecting strips. Limiting blocks are integrally formed on the surface of the four sides of the power distribution cabinet.

[0012] In one possible implementation, both the first and second connecting strips are fastened to the outside of the corresponding limiting block through positioning slots. The two L-shaped corner seats are adjustablely connected to the two ends of the second or first connecting strip. Bolts pass through the outside of the corner of the L-shaped corner seat and are assembled and fixed to the target position.

[0013] In one possible implementation, guide rods are welded to one end of each of the two outer sides of the L-shaped corner bracket, and a nut is threaded to one end of each guide rod. Movable grooves are provided inside both ends of the second connecting strip and the first connecting strip. The second connecting strip is fastened to the outside of the guide rods on the two horizontal sides of the two L-shaped corner brackets through the movable grooves, and the first connecting strip is fastened to the outside of the guide rods on the two vertical sides of the two L-shaped corner brackets through the movable grooves.

[0014] In one possible implementation, the guide rod slides inside the movable groove, and the nut is threadedly connected to the guide rod in a direction away from the L-shaped corner seat, thereby assembling and fixing the second connecting strip or the first connecting strip to the L-shaped corner seat.

[0015] In one possible implementation, the first and second connecting strips are welded to a plate base at one side away from the distribution cabinet, and bolts pass through the interior of the plate base to assemble and fix it to the target position.

[0016] In one possible implementation, the cross-section of the positioning slot and the cross-section of the limiting block are both right-angled trapezoids, the thickness of the positioning slot is greater than the thickness of the limiting block, and the inclined surface of the limiting block away from the distribution cabinet and the inclined inner wall of the positioning slot both face the front of the distribution cabinet.

[0017] In one possible implementation, the four L-shaped corner brackets, two second connecting strips, and two first connecting strips are fitted onto the outside of the distribution cabinet. The positioning slots and limiting blocks on the second and first connecting strips work together to press the distribution cabinet into the target position to achieve a fixed state.

[0018] The beneficial effects of this application are as follows:

[0019] Firstly, in this solution, the second connecting strip is fastened to the outside of the guide rod on the two horizontal sides of the two L-shaped corner seats via the movable groove, and the first connecting strip is fastened to the outside of the guide rod on the two vertical sides of the two L-shaped corner seats via the movable groove. The guide rod is supported to slide inside the movable groove to adjust the distance between the two L-shaped corner seats, thereby realizing the scaling function of the four L-shaped corner seats. This makes it easier to adapt to the state of the power distribution cabinet after the size and space are adjusted according to the existing technology.

[0020] Secondly, in this solution, the limiting block on the outer wall of the power distribution cabinet is adapted to the positioning slot with a right-angled trapezoidal cross section. When the second connecting strip and the first connecting strip are connected to the L-shaped corner seat, the positioning slot and the limiting block on the second connecting strip and the first connecting strip can be used to press the power distribution cabinet into the target position to achieve a fixing effect.

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] Example 1:

[0027] This embodiment describes the specific structure of an adjustable distribution cabinet frame, as detailed in the following reference. Figures 1-3 As shown, it includes two first connecting strips 3 arranged symmetrically on the left and right, two second connecting strips 7 arranged symmetrically on the top and bottom, four L-shaped corner brackets 2 and a power distribution cabinet. The middle of the two first connecting strips 3 and the two second connecting strips 7 are provided with positioning slots 9. Limiting blocks 10 are integrally formed on the surface of the four sides of the power distribution cabinet 1.

[0028] Among them, the four L-shaped corner brackets 2 are all L-shaped, and the four L-shaped corner brackets 2 are located at one end of the second connecting strip 7 and the first connecting strip 3 respectively. The first connecting strip 3 and the second connecting strip 7 are fastened to the outside of the corresponding limiting block 10 through the positioning slot 9. The two L-shaped corner brackets 2 are adjustablely connected to the two ends of the second connecting strip 7 or the first connecting strip 3. When the bolt passes through the outside of the corner of the L-shaped corner bracket 2 and is assembled and fixed with the target position, the effect of fixing the power distribution cabinet 1 to the target position after scaling up and down can be achieved, which greatly improves the applicability and is not limited by the traditional fixing method.

[0029] Secondly, to facilitate the scaling function of the four L-shaped corner brackets 2 using two second connecting strips 7 and two first connecting strips 3, such as... Figure 1 and Figure 2 As shown, guide rods 5 are welded to one end of each of the two outer sides of the L-shaped corner bracket 2. A nut 8 is threaded to one end of each guide rod 5. Movable grooves 4 are provided inside both ends of the second connecting strip 7 and the first connecting strip 3. By having the second connecting strip 7 fasten to the outside of the guide rods 5 on the two horizontal sides of the two L-shaped corner brackets 2 via the movable grooves 4, and the first connecting strip 3 fasten to the outside of the guide rods 5 on the two vertical sides of the two L-shaped corner brackets 2 via the movable grooves 4, the guide rods 5 can slide inside the movable grooves 4. By having the nut 8 threadedly connected to the guide rod 5 in a direction away from the L-shaped corner bracket 2, the second connecting strip 7 or the first connecting strip 3 can be assembled and fixed to the L-shaped corner bracket 2. This completes the fixing work after the distance between the two L-shaped corner brackets 2 is adjusted, so as to adapt to the state of the power distribution cabinet 1 after the size and space are adjusted according to the existing technology.

[0030] Furthermore, to prevent the second connecting strip 7 or the first connecting strip 3 from sliding arbitrarily between the two first connecting strips 3, such as Figure 1 and Figure 2 As shown, the first connecting strip 3 and the second connecting strip 7 are welded to a plate base 6 on one side away from the distribution cabinet 1. By passing bolts through the inside of the plate base 6 and assembling and fixing it to the target position, the fixing effect of the second connecting strip 7 or the first connecting strip 3 can be achieved.

[0031] Furthermore, to facilitate the installation of the four L-shaped corner brackets 2, two second connecting strips 7, and two first connecting strips 3 onto the outside of the distribution cabinet 1, and to fix the distribution cabinet 1 to the target position, such as... Figure 3 As shown, the cross-section of the positioning slot 9 and the cross-section of the limiting block 10 are both right-angled trapezoids. The thickness of the positioning slot 9 is greater than the thickness of the limiting block 10. The inclined surface of the limiting block 10 away from the distribution cabinet 1 and the inclined inner wall of the positioning slot 9 both face the front of the distribution cabinet 1. By attaching the four L-shaped corner brackets 2, the two second connecting strips 7 and the two first connecting strips 3 to the outside of the distribution cabinet 1, the distribution cabinet 1 can be pressed into the target position by means of the positioning slots 9 on the second connecting strips 7 and the first connecting strips 3 and the limiting block 10, so as to achieve the fixing effect.

[0032] The above design sets L-shaped corner brackets 2 at the four corners of the distribution cabinet 1, sets a first connecting strip 3 on the vertical side of the distribution cabinet 1, and sets a second connecting strip 7 on the horizontal side of the distribution cabinet 1. The second connecting strip 7 is fastened to the outside of the guide rods 5 on the two horizontal sides of the two L-shaped corner brackets 2 by means of the movable groove 4, and the first connecting strip 3 is fastened to the outside of the guide rods 5 on the two vertical sides of the two L-shaped corner brackets 2 by means of the movable groove 4. The guide rods 5 slide inside the movable groove 4 to adjust the distance between the two L-shaped corner brackets 2, so as to realize the scaling function of the four L-shaped corner brackets 2. The nut 8 is threaded to the guide rod 5 in the direction away from the L-shaped corner brackets 2, and the second connecting strip 7 or the first connecting strip 3 is assembled and fixed to the L-shaped corner brackets 2. The fixing work after the distance of the two L-shaped corner brackets 2 is adjusted can be completed to adapt to the state of the distribution cabinet 1 after the size space is adjusted according to the existing technology.

[0033] Meanwhile, the limiting block 10 on the outer wall of the power distribution cabinet 1 is adapted to the positioning slot 9 with a right-angled trapezoidal cross section. When the second connecting strip 7 and the first connecting strip 3 are connected to the L-shaped corner seat 2, the positioning slot 9 on the second connecting strip 7 and the first connecting strip 3 and the limiting block 10 cooperate to press the power distribution cabinet 1 at the target position to achieve a fixed effect, which is simple and convenient.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
