Description

Technical Field

[0001] This utility model relates to the technical field of power distribution cabinet components, specifically the frame structure of a power distribution cabinet. Background Technology

[0002] As is already known, the distribution cabinet is formed by a frame, side walls, rear wall, top and bottom, wherein the frame is formed by vertical and horizontal members.

[0003] Patent CN1320713C discloses a frame for a power distribution cabinet. The frame is unique in that it has a substantially triangular cross-section. The frame comprises a first part, a second part, a central part, a third part, and a fourth part. The third and fourth parts form the sides of the triangle and are connected at the vertices. The first and second parts are connected by the central part and each forms an angle with the central part. The first part is connected to the third part, and the second part is connected to the fourth part. The frame includes two ribs extending longitudinally. These ribs are integral with the frame and are positioned at the angles between the first and third parts and between the second and fourth parts, respectively. This arrangement allows for the joining of decorative elements for the frame while simultaneously reinforcing the structure of the shaped components forming the frame.

[0004] The existing technology described above uses a method of attaching two objects together for positioning and fixation. However, to strengthen the structural strength between the frame and the decoration, welding or bolting is required, which may compromise the aesthetics of the decoration. Furthermore, the contact area between the frame and the decoration is small, making it prone to breakage under pressure. Therefore, we propose a new frame structure for the distribution cabinet. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a frame structure for a power distribution cabinet, including a frame body, a decorative element disposed on the outside of the frame body, a first support section disposed on one side of the decorative element, and limit sections disposed on both sides of the first support section. The decorative element includes a panel section disposed on one side of the frame body, and plug-in sections are symmetrically disposed on one side of the panel section, and the plug-in sections and limit sections are adapted to each other.

[0006] In some embodiments, both the insertion segment and the limiting segment are configured with a hook-shaped structure, and the insertion segment and the limiting segment slide together.

[0007] In some embodiments, a plurality of protrusions are provided on the outer side of the plug section, and a plurality of grooves are provided on one side of the limiting section, with the grooves corresponding to the protrusions, and a friction-enhancing sleeve is provided in the groove.

[0008] In some embodiments, an extension section is provided on one side of the limiting section, and a fixing section is provided on both sides of the panel section, and the shapes of the fixing section and the extension section are adapted to each other.

[0009] In some embodiments, a reinforcing section is provided at the connection between the first supporting section and the limiting section, a reinforcing rib is provided on one side of the reinforcing section, and a first connecting section is provided in the middle section of the first supporting section.

[0010] In some embodiments, a second support section is provided on one side of the first support section, and the first support section and the second support section form a rhomboid structure.

[0011] In some embodiments, a second connecting segment is provided at the connection between the first support segment and the second support segment.

[0012] This utility model has at least the following beneficial effects:

[0013] The decorative elements are installed using a sliding fit between the plug-in section and the limiting section. The contact area between the two is large, the stress structure is stable, and the operator only needs to perform a simple sliding operation to complete the installation. At the same time, it avoids the defects such as weld points and screw holes left by welding or bolting on the decorative elements, which affect the appearance. This makes the distribution cabinet look cleaner and more beautiful, and improves the overall quality of the product.

[0014] The design of the protrusions, grooves, and friction-enhancing sleeves increases the friction between the insertion section and the limiting section, effectively preventing relative sliding between the two during use. The secondary fixing structure of the extension section and the fixed section further increases the contact area and structural strength of the connection part.

[0015] The design of reinforced sections, reinforcing ribs, and diamond-shaped structure enhances the overall structural strength of the frame and effectively extends its service life. At the same time, the enhanced structural strength enables the distribution cabinet to better protect the internal electrical components and reduce the risk of damage to internal components when subjected to external impacts or vibrations.

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] The distribution cabinet's frame structure includes a frame body 1, with a decorative element 2 on the outside of the frame body 1. The frame body 1 includes a first support section 8 on one side of the decorative element 2, and limit sections 7 on both sides of the first support section 8. The decorative element 2 includes a panel section 3 on one side of the frame body 1, with symmetrically arranged plug-in sections 6 on one side of the panel section 3. The plug-in sections 6 and the limit sections 7 are compatible, and both the plug-in sections 6 and the limit sections 7 are hook-shaped. The plug-in sections 6 and the limit sections 7 slide against each other. The limit sections 7 are designed with a hook-like shape. Designed as a hook-shaped structure, with the hook-shaped opening facing outwards from the frame 1, the hook-shaped structure is used to cooperate with the insertion section 6 of the decorative element 2 to achieve initial positioning and limiting of the decorative element 2. The insertion section 6 is integrally formed with the panel section 3, and the shape of the insertion section 6 is also hook-shaped, which is adapted to the hook-shaped structure of the limiting section 7. The size of the hook-shaped part of the insertion section 6 and the size of the hook-shaped part of the limiting section 7 allow for a sliding fit between them. When the insertion section 6 is inserted into the hook-shaped structure of the limiting section 7, a tight connection can be achieved.

[0026] When in use, the operator aligns the plug section 6 of the decoration 2 with the limiting section 7 of the frame 1, and then pushes the decoration 2 along the sliding direction so that the plug section 6 and the limiting section 7 engage with each other, completing the initial installation of the decoration 2 and the frame 1. This installation method, which uses welding or bolt fixing, will not affect the panel section 3 in the decoration 2, and the two have a large contact area and a stable stress structure. At the same time, the operation is simple and the appearance is neat and beautiful after installation.

[0027] Example 2

[0028] Please see Figures 1-5This utility model provides a technical solution:

[0029] The outer side of the plug section 6 is provided with several protrusions 14, and the side of the limiting section 7 is provided with several grooves 15, and the grooves 15 correspond to the protrusions 14. The grooves 15 are provided with friction-enhancing sleeves 16. The protrusions 14 are hemispherical. The plug section 6 is integrally formed. The side of the limiting section 7 is provided with multiple grooves 15 corresponding to the position of the protrusions 14. The shape and size of the grooves 15 match the protrusions 14. The grooves 15 are provided with friction-enhancing sleeves 16. The friction-enhancing sleeves 16 are made of nitrile rubber, which has good wear resistance and elasticity. Its inner diameter is the same as the inner diameter of the groove 15, and its outer diameter is slightly larger than the opening diameter of the groove 15. It is installed in the groove 15 by interference fit.

[0030] Unlike Embodiment 1, when the insertion segment 6 and the limiting segment 7 are slidably engaged, the protrusion 14 will be embedded in the groove 15 and in close contact with the friction-enhancing sleeve 16. The presence of the friction-enhancing sleeve 16 not only increases the friction between the protrusion 14 and the groove 15, preventing relative sliding between the insertion segment 6 and the limiting segment 7 during use, but also absorbs a certain amount of vibration and impact, further improving the stability and reliability of the connection between the decoration 2 and the frame 1.

[0031] Example 3

[0032] Please see Figures 1-5 This utility model provides a technical solution:

[0033] An extension section 5 is provided on one side of the limiting section 7, and a fixing section 4 is provided on both sides of the panel section 3, and the shapes of the fixing section 4 and the extension section 5 are compatible.

[0034] Unlike Embodiment 1, after the insertion section 6 of the decorative element 2 and the limiting section 7 of the frame body 1 have completed the initial engagement, the fixing sections 4 on both sides of the panel section 3 can be accurately fitted onto the extension section 5 to form a secondary fixation. This fixing method further increases the contact area between the decorative element 2 and the frame body 1. Through the tight cooperation between the extension section 5 and the fixing section 4, the external pressure can be effectively dispersed and the structural strength of the connection part can be improved. Even when subjected to greater pressure, it is not easy to break.

[0035] Example 4

[0036] Please see Figures 1-5 This utility model provides a technical solution:

[0037] A reinforcing section 13 is provided at the connection between the first supporting section 8 and the limiting section 7. A reinforcing rib 10 is provided on one side of the reinforcing section 13. A first connecting section 11 is provided in the middle of the first supporting section 8. A second supporting section 9 is provided on one side of the first supporting section 8. The first supporting section 8 and the second supporting section 9 form a rhomboid structure.

[0038] Unlike Embodiment 1, the overall structural strength of the frame 1 is improved by setting up the reinforcing section 13, the reinforcing rib 10, the first connecting section 11, the second supporting section 9, and the second connecting section 12. The reinforcing section 13 and the reinforcing rib 10 enhance the strength at the connection between the first supporting section 8 and the limiting section 7, preventing deformation or breakage of this part under stress. The rhomboid structure formed by the first connecting section 11, the second supporting section 9, and the second connecting section 12 optimizes the stress distribution of the frame 1, enabling the frame 1 to withstand greater external loads and improving the stability and reliability of the power distribution cabinet frame.

[0039] Working principle:

[0040] When installing decorative element 2, the operator aligns the insert segment 6 of decorative element 2 with the hook-shaped structure of the limiting segment 7 of frame 1, and then applies a certain pushing force along the sliding direction. Since both insert segment 6 and limiting segment 7 are hook-shaped and their shapes are compatible, under the action of the pushing force, insert segment 6 inserts into the hook-shaped structure of limiting segment 7, achieving a sliding engagement between the two. When insert segment 6 and limiting segment 7 are in sliding engagement, the protrusion 14 on the outer side of insert segment 6 will embed into the groove 15 of limiting segment 7, making close contact with the friction-enhancing sleeve 16. The elasticity and high coefficient of friction of the friction-enhancing sleeve 16 increase the friction between the protrusion 14 and the groove 15, making the connection between insert segment 6 and limiting segment 7 more stable. After the insert segment 6 and limiting segment 7 have completed the initial engagement, the panel section... The fixed sections 4 on both sides fit onto the extension sections 5 of the limiting section 7. The tight fit between the fixed sections 4 and the extension sections 5 forms a secondary fixing structure, further increasing the contact area and connection strength between the decorative element 2 and the frame 1. The shape design of the fixed sections 4 and the extension sections 5 allows them to restrict each other's movement, thus sharing the load when subjected to external pressure and preventing the connection from breaking due to excessive local stress. The rhomboid structure formed by the first connecting section 11, the second supporting section 9, and the second connecting section 12 changes the force path of the frame 1. When subjected to force, the rhomboid structure can transmit the force along the diagonal direction of the rhombus, making the force distribution within the frame 1 more uniform. This structural design improves the load-bearing capacity of the frame 1, enabling it to withstand greater external pressure and impact, ensuring the stability and reliability of the distribution cabinet frame under various working conditions.

[0041] 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.
