Description

Technical Field

[0001] This utility model belongs to the field of distribution box technology, and particularly relates to a secondary distribution box. Background Technology

[0002] Secondary distribution boxes, also called sub-boxes, are generally responsible for a power supply area and are widely used in various construction sites. Existing secondary distribution boxes require separate packaging of the box frame and the box itself during transportation, resulting in a large space occupation. When the box is placed in a wooden crate, exposed electrical wiring parts are easily damaged by impacts.

[0003] The existing patent document "A Secondary Distribution Box" (Announcement No.: CN213520871U) discloses "a bracket for installing and supporting the box body, and an external industrial socket is used on the box body", which also has the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a secondary distribution box with a novel structure. When in use, the distribution box bracket supports the distribution box body, which has high stability. When stored, the distribution box bracket protects the distribution box body from direct external impact and prevents damage to electrical wiring parts from collisions during transportation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A secondary distribution box includes a box body, characterized in that it further includes a distribution box bracket, a baffle, and end bolts. The distribution box bracket has a receiving cavity, and the height of the baffle is adapted to the height of the receiving cavity. When the distribution box body is placed on top of the distribution box bracket, the end bolts connect the distribution box body and the distribution box bracket, and the baffle is engaged in the receiving cavity. The bottom plate of the distribution box bracket provides support to the top plate of the distribution box bracket through the baffle. When the distribution box body is engaged in the receiving cavity, the baffle is located inside the receiving cavity, and the end bolts connect the baffle to the distribution box bracket. The baffle, in conjunction with the distribution box bracket, covers the distribution box body to restrict its free movement. This secondary distribution box has a novel structure. During use, the distribution box bracket supports the distribution box body, providing high stability. During storage, the distribution box bracket protects the distribution box body from direct external impacts and prevents damage to electrical wiring components during transportation.

[0007] Furthermore, the back plate of the distribution box bracket has longitudinally distributed positioning protrusions, and the side of the baffle is provided with positioning holes corresponding to the positioning protrusions, so as to realize the quick positioning of the baffle in the receiving cavity, reduce the positioning difficulty, prevent the baffle from tilting freely, and keep it upright, thereby providing continuous support.

[0008] Furthermore, the inner wall of the distribution box bracket is equipped with elastic pads. When the distribution box is installed into the receiving cavity, the elastic pads make close contact with the sides of the distribution box, avoiding collision damage caused by rigid contact and providing simple protection for the distribution box.

[0009] Furthermore, the front of the distribution box has a downward-sloping mounting surface with a terminal block on it. The mounting surface faces the workers for easy wiring.

[0010] Furthermore, the front of the distribution box is provided with a wiring groove, and a cover plate is rotatably connected inside the wiring groove. A limit block is provided inside the wiring groove, and the limit block abuts against the bottom surface of the cover plate to restrict the free rotation of the cover plate. The cover plate is not easy to open freely, thereby stably sealing the wiring groove and preventing short circuits or damage to the lines due to moisture, dust or external force.

[0011] Furthermore, the distribution box bracket includes a top plate, a bottom plate, a back plate, and support columns. The support columns and back plate are located between the top plate and the bottom plate, and the back plate is located between two support columns. Triangular reinforcing plates are provided between the support columns and the top plate, and between the support columns and the bottom plate. The distribution box bracket has a stable structure, strong load-bearing capacity, and reliable operation.

[0012] Furthermore, the base plate of the distribution box bracket is provided with a strip-shaped through hole for anchor bolts to pass through. Anchor bolts are inserted into the strip-shaped through hole and driven into the ground to fix the distribution box bracket in place and prevent the distribution box bracket from tipping over freely.

[0013] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0014] 1. In use, first place the distribution box on top of the distribution box bracket. Then, pass the end bolts from bottom to top through the fixing through hole and connect them to the second threaded hole on the bottom surface of the distribution box to lock the distribution box and prevent it from tipping over. Next, fit the positioning hole of the baffle onto the positioning protrusion on the back plate so that the baffle is positioned and snapped into the receiving cavity. This allows the bottom plate to support the top plate through the baffle, which distributes the pressure of the top plate to the bottom plate, reducing the pressure on the top plate and preventing the distribution box bracket from deforming due to excessive pressure. This improves the load-bearing capacity of the distribution box bracket. The distribution box bracket supports the distribution box, which does not contact the ground, thus preventing moisture and insects.

[0015] 2. When storing, first insert the distribution box into the receiving cavity, then insert the baffle into the receiving cavity, and then connect the end bolt from top to bottom through the fixing through hole to the first threaded hole on the top surface of the baffle to lock the baffle and prevent it from sliding freely. The baffle, together with the distribution box bracket, covers the distribution box and restricts the free movement of the distribution box, protecting the distribution box from direct external impact and preventing damage to the electrical wiring parts during transportation.

[0016] 3. The baffle can be used to reinforce the distribution box bracket, or to prevent the distribution box from falling out of the distribution box bracket. It serves two purposes and is highly practical. Attached Figure Description

Detailed Implementation

[0026] like Figures 1 to 7 As shown, this utility model discloses a secondary distribution box, comprising: a distribution box body 1, a distribution box bracket 2, a baffle 3, and end bolts 4. The distribution box bracket 2 includes a top plate 5, a bottom plate 6, a back plate 7, and support columns 8. The support columns 8 and the back plate 7 are fixed between the top plate 5 and the bottom plate 6. The back plate 7 is fixed between the two support columns 8. Triangular reinforcing plates 9 are fixed between the support columns 8 and the top plate 5, and between the support columns 8 and the bottom plate 6. The distribution box bracket 2 has a stable structure, strong load-bearing capacity, and reliable use.

[0027] The base plate 6 is provided with a strip-shaped through hole 10 for anchor bolts to pass through. Anchor bolts are inserted into the strip-shaped through hole 10 and driven into the ground to fix the distribution box bracket 2 on the spot and prevent the distribution box bracket 2 from tipping over freely.

[0028] The top plate 5 has a strip-shaped groove 11, and the strip-shaped groove 11 has a fixing through hole 12 corresponding to the end bolt 4. The top surface of the baffle 3 has a first threaded hole 13 that is screwed into the end bolt 4. The bottom surface of the distribution box 1 has a second threaded hole 14 that is screwed into the end bolt 4. The back plate 7 has longitudinally distributed positioning protrusions 15, and the side of the baffle 3 has positioning holes 16 corresponding to the positioning protrusions 15.

[0029] A receiving cavity 17 is formed between the top plate 5, the bottom plate 6, the back plate 7, and the support column 8, and the height of the baffle 3 is adapted to the height of the receiving cavity 17.

[0030] In use, first place the distribution box 1 on top of the distribution box bracket 2, then pass the end bolt 4 from bottom to top through the fixing through hole 12 and connect it to the second threaded hole 14 on the bottom surface of the distribution box 1 to lock the distribution box 1 and prevent it from tipping over. Then, fit the positioning hole 16 of the baffle 3 onto the positioning protrusion 15 on the back plate 7, so that the baffle 3 is positioned and locked into the receiving cavity 17. This allows the bottom plate 6 to support the top plate 5 through the baffle 3. The baffle 3 distributes the pressure of the top plate 5 to the bottom plate 6, reducing the pressure on the top plate 5 and preventing the distribution box bracket 2 from being deformed due to excessive pressure. This improves the load-bearing capacity of the distribution box bracket 2. The distribution box bracket 2 supports the distribution box 1, which does not contact the ground, thus preventing moisture and insects.

[0031] When storing, first insert the distribution box 1 into the receiving cavity 17, then insert the baffle 3 into the receiving cavity 17, and then connect the end bolt 4 from top to bottom through the fixing through hole 12 to the first threaded hole 13 on the top surface of the baffle 3 to lock the baffle 3 and prevent the baffle 3 from sliding freely. The baffle 3, together with the distribution box bracket 2, covers the distribution box 1, restricts the free movement of the distribution box 1, protects the distribution box 1 from direct external impact, and prevents damage to the electrical wiring parts during transportation.

[0032] An elastic pad 18, made of rubber, is adhered and fixed to the inner wall of the triangular reinforcing plate 9. When the distribution box 1 is installed into the receiving cavity 17, the elastic pad 18 is in close contact with the side of the distribution box 1, avoiding collision damage caused by rigid contact and providing simple protection for the distribution box 1.

[0033] The front of the distribution box 1 has a downward-sloping mounting surface, on which a terminal block 19 is provided. The mounting surface faces the staff for easy wiring.

[0034] The front of the distribution box 1 is provided with a wiring groove 20, and a cover plate 21 is rotatably connected inside the wiring groove 20. A limit block 22 is provided inside the wiring groove 20. Flipping the cover plate 21 upwards can expose the wiring groove 20. Flipping the cover plate 21 downwards causes its bottom surface to abut against the limit block 22, thereby restricting the free rotation of the cover plate 21. The cover plate 21 is not easy to open freely, thus stably sealing the wiring groove 20 and preventing short circuits or damage to the circuit due to moisture, dust or external force.

[0035] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
