Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and specifically provides a box body structure of a distribution box. Background Art

[0002] The box body structure of a distribution box is designed to protect the internal electrical components, ensure safe operation, and facilitate maintenance. According to its size and capacity, the box body structure of a distribution box can be divided into small boxes, medium boxes, and large boxes. Among them, medium and large boxes are mainly applicable to commercial buildings, small and medium-sized factories, or large industrial facilities and data centers.

[0003] The box body structures of medium or large distribution boxes are mostly assembled by multiple box frames with support plates. At present, when assembling the box body structure of a distribution box, the connection and fixation between each box frame and between the support plates are not integrated. Not only does it take a lot of time to fix the support plates and box frames one by one, but it also reduces the stability of the box body structure, resulting in the box body structure of the distribution box being easily deformed by external pressure or impact during transportation, installation, or use. Especially in an industrial environment, this may lead to the instability of the box body structure, affecting the safety of the internal electrical components. Moreover, the distribution box is generally heavy, and the support plates for supporting the distribution box are prone to insufficient support force, posing a hidden danger to the safety of placing the distribution box. Summary of the Invention

[0004] In view of the above problems, the embodiments of the present application provide a box body structure of a distribution box to solve the technical problems in the related art.

[0005] To achieve the above object, the embodiments of the present application provide the following technical solutions: A box body structure of a distribution box, comprising: a plurality of rectangular frames arranged horizontally. On the opposite surfaces of the two vertical sections of the rectangular frame arranged along its length direction, insertion holes are uniformly arranged from top to bottom. On both sides of the rectangular frame arranged along its length direction, side plates are installed. End plates are installed at the top and bottom of the rectangular frame. On one side of the rectangular frame arranged along its width direction, a panel is installed.

[0006] A plurality of support plates arranged from top to bottom are installed inside the rectangular frame. The support plates are connected to the rectangular frame through a locking group. A vertical locking group for uniformly locking the plurality of support plates and locking the adjacent two rectangular frames is commonly installed on the adjacent two rectangular frames.

[0007] The locking group includes receiving grooves opened on both sides of the support plate arranged along its length direction. A supplementary plate is slidably connected to the receiving groove. One side of the supplementary plate located inside the receiving groove is inserted into the corresponding insertion hole through an insertion member. The supplementary plate and the receiving groove are connected through a pushing spring. A locking hole penetrating up and down is opened in the middle of the supplementary plate. An auxiliary supporting component is arranged between the lower end surface of the supplementary plate and the side plate.

[0008] The vertical locking group includes a T-shaped insert with a T-shaped horizontal cross-section and an H-shaped insert with an H-shaped horizontal cross-section. T-shaped grooves are symmetrically arranged along the length direction at the top of the rectangular frame and penetrate through the side plates. The T-shaped grooves on two adjacent rectangular frames form an H-shaped groove. The H-shaped insert is inserted between the two adjacent T-shaped grooves of two adjacent rectangular frames, and the T-shaped insert is inserted into another T-shaped groove on the rectangular frame at the edge among the laterally arranged multiple rectangular frames. Locking members for locking the supplementary plate are installed on both the H-shaped insert and the T-shaped insert.

[0009] A transverse locking group for locking the T-shaped insert, the H-shaped insert, and the multiple rectangular frames to form a box structure is installed between the end plates at the bottoms of the multiple rectangular frames.

[0010] In a possible implementation manner, the locking member includes lower inserting posts uniformly arranged from top to bottom and installed on the end face close to the supporting plate after the H-shaped insert and the T-shaped insert are inserted into the corresponding T-shaped grooves. The locking holes are inserted into the corresponding lower inserting posts.

[0011] In a possible implementation manner, the auxiliary supporting assembly includes a triangular supporting seat installed on the lower end face of the supplementary plate. A through groove penetrating through the supporting plate is opened on the lower end face of the receiving groove. Insert blocks symmetrically arranged along the length direction of the triangular supporting seat are installed on the side wall of the triangular supporting seat. Slots are opened on the side plates uniformly arranged from top to bottom and located on both sides of the T-shaped groove. The insert blocks are inserted into the corresponding slots.

[0012] In a possible implementation manner, the plugging member includes ear plates installed at both ends of the supplementary plate arranged along the length direction on one side within the receiving groove. Plug rods are installed on the ear plates. The plug rods penetrate through the supporting plate and are inserted into the corresponding jacks. The ends of the plug rods are arc-shaped.

[0013] In a possible implementation manner, an inclined rod inserted into the jack is installed on the lower side wall of the plug rod. A sliding groove for sliding connection with the inclined rod is opened on the supporting plate. The sliding groove communicates with the receiving groove. The inclined rod, the plug rod, and the vertical section of the rectangular frame form a triangle.

[0014] In a possible implementation manner, the transverse locking group includes an insertion lock frame, which is composed of three insertion lock rods and an end connection plate commonly installed at one end of the three insertion lock rods. Three through holes are uniformly arranged along the width direction on the end plate at the bottom of the rectangular frame. The T-shaped groove communicates with the through hole, and the through hole penetrates through the lower ends of the H-shaped insert and the T-shaped insert. The three insertion lock rods are respectively inserted into the corresponding through holes to connect the multiple end plates, and a fixing member is commonly installed after the three insertion lock rods pass through the corresponding through holes.

[0015] In a possible implementation manner, the fixing member includes a locking plate sleeved jointly after three latch rods pass through corresponding sleeve holes. A threaded sleeve is rotatably installed in the middle of the locking plate.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Refer to Figure 1 And Figure 7, a box body structure of a distribution box, comprising: a plurality of rectangular frames 1 arranged horizontally, the opposite surfaces of the two vertical sections of the rectangular frame 1 arranged along its length direction are provided with insertion holes 2 arranged uniformly from top to bottom, both sides of the rectangular frame 1 arranged along its length direction are provided with side plates 3, both the top and bottom of the rectangular frame 1 are provided with end plates 4, and one side of the rectangular frame 1 arranged along its width direction is provided with a panel 5.

[0035] Refer to Figure 1 and Figure 7 , a plurality of supporting plates 6 arranged from top to bottom are installed in the rectangular frame 1, the supporting plates 6 are connected to the rectangular frame 1 through a locking group 7, and a vertical locking group 8 for uniformly locking a plurality of supporting plates 6 and locking two adjacent rectangular frames 1 together is installed on two adjacent rectangular frames 1.

[0036] Refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 , the locking group 7 includes receiving grooves 70 opened on both sides of the supporting plate 6 arranged along its length direction, a supplementary plate 71 is slidably connected to the receiving grooves 70, one side of the supplementary plate 71 located in the receiving grooves 70 is inserted into the corresponding insertion hole 2 through an inserting member 72, the supplementary plate 71 and the receiving grooves 70 are connected through a pushing spring 73, a locking hole 74 penetrating up and down is opened in the middle of the supplementary plate 71, and an auxiliary supporting assembly 75 is arranged between the lower end surface of the supplementary plate 71 and the side plate 3.

[0037] In the initial state, the supplementary plate 71 is extruded into the receiving groove 70 by the convex block connected to the lower end of the supplementary plate 71, so as to facilitate the insertion of the supporting plate 6 into the rectangular frame 1. When the position of the supporting plate 6 is determined and the inserting member 72 is aligned with the corresponding insertion hole 2, the convex block is released, and the supplementary plate 71 and the inserting member 72 extend out of the receiving groove 70 under the elastic force of the pushing spring 73. At this time, the inserting member 72 is inserted into the insertion hole 2 and inserted with the insertion hole 2, so as to realize the pre-support and fixation of the supporting plate 6. After that, when all the supporting plates 6 are placed, the vertical locking group 8 is used to uniformly lock and limit a plurality of supporting plates 6 arranged from top to bottom on two adjacent rectangular frames 1, thereby improving the convenience of locking a plurality of supporting plates 6.

[0038] At the same time, the auxiliary supporting assembly 75 is connected to the side plate 3 to support the supplementary plate 71 and the supporting plate 6, thereby increasing the supporting force when the supporting plate 6 supports the distribution box, and further improving the stability of the placement of the distribution box.

[0039] Refer to Figure 1 , Figure 3 , Figure 7 and Figure 8, the vertical locking group 8 includes a T-shaped insert 80 with a T-shaped horizontal cross-section and an H-shaped insert 81 with an H-shaped horizontal cross-section. T-shaped slots are provided at the top of the rectangular frame 1, symmetrically arranged along its length direction and penetrating through the side plates 3. The T-shaped slots on two adjacent rectangular frames 1 form an H-shaped slot. The H-shaped insert 81 is inserted between two adjacent T-shaped slots of two adjacent rectangular frames 1, and the T-shaped insert 80 is inserted into another T-shaped slot on the rectangular frame 1 at the edge among the laterally arranged multiple rectangular frames 1. Locking members 82 for locking the supplementary plate 71 are installed on both the H-shaped insert 81 and the T-shaped insert 80.

[0040] Refer to Figure 1 and Figure 3 , a transverse locking group 9 for locking the T-shaped insert 80, the H-shaped insert 81, and the multiple rectangular frames 1 to form a box structure is installed between the end plates 4 at the bottom of the multiple rectangular frames 1.

[0041] When assembling the box body, align the multiple rectangular frames 1, then insert the H-shaped insert 81 into two aligned T-shaped slots on two adjacent rectangular frames 1. The two rectangular frames 1 are limited and locked in connection under the insertion and cooperation of the H-shaped insert 81 and the two T-shaped slots. The T-shaped insert 80 is inserted into the T-shaped slots on the sides of the rectangular frames 1 arranged laterally on both sides. Then, insert multiple supporting plates 6 into the rectangular frames 1, adjust the distance between the supporting plates 6 according to the required spacing, and then fasten the supporting plates 6 and the rectangular frames 1 through the locking group 7. After all the multiple supporting plates 6 are connected to the rectangular frames 1, press down the H-shaped insert 81 and the T-shaped insert 80, and the two drive the locking members 82 to move downward. The locking members 82 above the supplementary plate 71 are inserted into the locking holes 74 to lock the position of the supplementary plate 71, thereby realizing the integrated locking of the multiple supporting plates 6, greatly improving the convenience and efficiency of locking the supporting plates 6, avoiding the shaking or falling of the supporting plates 6 caused by the dragging during equipment placement, and further improving the stability of the fixation of the supporting plates 6.

[0042] After the supporting plates 6 are locked, the T-shaped insert 80, the H-shaped insert 81, and the multiple rectangular frames 1 are integrally locked through the transverse locking group 9, which not only improves the efficiency and convenience of locking and fixing the T-shaped insert 80 and the H-shaped insert 81, but also locks the multiple rectangular frames 1 again in the horizontal direction, greatly improving the connection stability and firmness between the multiple rectangular frames 1 of the box structure.

[0043] Refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9, the auxiliary supporting component 75 includes a triangular supporting seat 750 installed on the lower end surface of the supplementary plate 71. A through groove penetrating the supporting plate 6 is formed on the lower end surface of the storage groove 70. Insert blocks 751 are symmetrically arranged along the length direction on the side wall of the triangular supporting seat 750. Slots 752 are formed on the side plate 3, which are uniformly arranged from top to bottom and are located on both sides of the T-shaped groove. The insert blocks 751 are inserted into the corresponding slots 752.

[0044] The triangular supporting seat 750 moves along with the supplementary plate 71. When the supplementary plate 71 extends out of the storage groove 70, the insert blocks 751 on the triangular supporting seat 750 are inserted into the corresponding slots 752, so that the triangular supporting seat 750 supports the supplementary plate 71 under the insertion and cooperation of the insert blocks 751 and the slots 752, and further supports the supporting plate 6, improving the supporting force of the supporting plate 6.

[0045] Refer to Figure 3 、 Figure 6 and Figure 7 , the locking member 82 includes a lower insertion post that is uniformly arranged from top to bottom and is installed on the end surface close to the supporting plate 6 after the H-shaped insertion bar 81 and the T-shaped insertion bar 80 are inserted into the corresponding T-shaped grooves. The locking holes 74 are inserted into the corresponding lower insertion posts, thereby locking the positions of the supporting plate 6 and the supplementary plates 71 at both ends thereof.

[0046] Refer to Figure 4 、 Figure 5 and Figure 6 , the inserting member 72 includes ear plates installed at both ends of the supplementary plate 71 located inside the storage groove 70 along its length direction. Insertion rods are installed on the ear plates. The insertion rods penetrate through the supporting plate 6 and are inserted into the corresponding insertion holes 2. The end of the insertion rod is arc-shaped (not shown in the figure) to facilitate the insertion of the insertion rod into the insertion hole 2. When the pushing spring 73 pushes the supplementary plate 71 to expand and contract in the storage groove 70, the supplementary plate 71 drives the insertion rod to move, so that the insertion rod extends out of the storage groove 70 and is inserted into the insertion hole 2. Through the insertion of the insertion rod into the corresponding insertion hole 2, the clamping connection between the supporting plate 6 and the rectangular frame 1 is realized.

[0047] Refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6 , an inclined rod 720 inserted into the insertion hole 2 is installed on the lower side wall of the insertion rod. A sliding groove 721 slidably connected to the inclined rod 720 is formed on the supporting plate 6. The sliding groove 721 communicates with the storage groove 70. The inclined rod 720, the insertion rod and the vertical section of the rectangular frame 1 form a triangle, so that a triangular stable structure is formed at the four corners of the supporting plate 6, thereby further improving the load-bearing capacity.

[0048] Refer to Figure 2 、 Figure 3 Figure 7, the horizontal locking group 9 includes a plug lock frame 90, which is composed of three plug lock rods 901 and an end connection plate 902 commonly installed at one end of the three plug lock rods 901. Three through-hole sleeves 91 are provided on the end plate 4 at the bottom of the rectangular frame 1 and are evenly arranged along its width direction. The T-shaped groove communicates with the through-hole sleeves 91, and the through-hole sleeves 91 penetrate through the lower ends of the H-shaped insert 81 and the T-shaped insert 80. The three plug lock rods 901 are respectively inserted into the corresponding through-hole sleeves 91 to connect multiple end plates 4, and a fixing member 92 is commonly installed after the three plug lock rods 901 pass through the corresponding through-hole sleeves 91.

[0049] Refer to Figure 2 , Figure 3 Figure 7 , the fixing member 92 includes a locking plate 920 commonly sleeved after the three plug lock rods 901 pass through the corresponding through-hole sleeves 91. A threaded sleeve 921 is rotatably installed in the middle of the locking plate 920. The threaded sleeve 921 is sleeved on the middle plug lock rod 901 and is connected to the plug lock rod 901 by means of threaded cooperation. The other two plug lock rods 901 are used to increase the connection points between multiple end plates 4 and improve the connection effect between multiple end plates 4.

[0050] After the T-shaped insert 80 and the H-shaped insert 81 are inserted downward and the supporting plate 6 is locked by the locking member 82, the three plug lock rods 901 are inserted into the corresponding through-hole sleeves 91 until the end connection plate 902 abuts against the end plate 4. Then, the locking plate 920 is sleeved on the other ends of the three plug lock rods 901, and the threaded sleeve 921 is rotated so that the threaded sleeve 921 is locked and connected to the corresponding plug lock rod 901 by means of threaded cooperation. The plug lock rods 901 cooperate with the T-shaped insert 80 and the H-shaped insert 81, not only locking multiple T-shaped inserts 80 and H-shaped inserts 81, but also integrally fixing the end plates 4 at the bottom of multiple rectangular frames 1, thereby improving the stability of the box body structure.

[0051] When assembling the box body, first align multiple rectangular frames 1, then insert the H-shaped insert 81 into two T-shaped grooves on two adjacent and aligned rectangular frames 1. The two rectangular frames 1 are limited and locked in connection under the insertion and matching action of the H-shaped insert 81 and the two T-shaped grooves. The T-shaped insert 80 is inserted into the T-shaped grooves on the sides of the rectangular frames 1 arranged horizontally on both sides. Then, multiple supporting plates 6 are inserted into the rectangular frames 1, the distance between the supporting plates 6 is adjusted according to the required spacing, and then the supporting plates 6 and the rectangular frames 1 are clamped by the clamping group 7.

[0052] After all the supporting plates 6 are connected to the rectangular frame 1, press down the H-shaped insert 81 and the T-shaped insert 80. The two drive the locking member 82 to move downward, and the locking member 82 above the supplementary plate 71 is inserted into the locking hole 74 to lock the position of the supplementary plate 71, thereby realizing the integrated locking of multiple supporting plates 6, greatly improving the convenience and efficiency of locking the supporting plates 6, avoiding the shaking or dropping of the supporting plates 6 caused by dragging during equipment placement, and further improving the stability of the fixation of the supporting plates 6.

[0053] After the supporting plate 6 is locked, the T-shaped insert 80, the H-shaped insert 81 and multiple rectangular frames 1 are integrally locked through the transverse locking group 9, which not only improves the efficiency and convenience of locking and fixing the T-shaped insert 80 and the H-shaped insert 81, but also locks the multiple rectangular frames 1 again in the transverse direction, greatly improving the connection stability and firmness between the multiple rectangular frames 1 of the box structure.
