Description

Technical Field

[0001] This utility model belongs to the technical field of busbar junction boxes, specifically relating to a busbar outgoing junction box with a fire-resistant and waterproof structure. Background Technology

[0002] Busbar trunking is a new type of circuit arrangement. It is a new type of conductor that uses copper or aluminum as conductors, is supported by non-alkaline insulation, and is then installed in a metal trough. The branch unit of busbar trunking refers to the switch cabinet or branch box that branches to its bypass in the busbar trunking circuit.

[0003] When existing busbar trunking and junction boxes are installed together, they are only connected by plugs and sockets. This single fixed-point connection structure may loosen at the connection point due to vibrations generated during long-term operation of the equipment, causing the junction box to shake and making the connection structure of the junction unit unstable.

[0004] Therefore, a busbar junction box with a fire-resistant and waterproof structure is proposed. Summary of the Invention

[0005] This utility model provides a busbar outlet junction box with a fire-resistant and waterproof structure, the purpose of which is to solve the problems mentioned above.

[0006] This utility model embodiment provides a busbar outlet junction box with a fire-resistant and waterproof structure, including a junction box body and a busbar trunking body, the junction box body being located above the busbar trunking body; an outlet junction platform disposed on the top of the busbar trunking body; an upper docking assembly disposed on the junction box body; and a lower docking assembly disposed on the outlet junction platform; wherein the upper docking assembly includes: a docking post disposed at the bottom of the junction box body; and a straight toothed groove formed on one side of the outer wall of the docking post; wherein the lower docking assembly includes: a docking groove formed on the top of the outlet junction platform; a guide post embedded in the inner wall of the docking groove; a support frame disposed at one end of the guide post; and a horizontal spring sleeved on the outer wall of the guide post near the outer wall of the support frame and the inner wall of the docking groove; a toothed plate rotating on the inner wall of the support frame; a torsion spring disposed between the toothed plate and the support frame; and a limiting block disposed on the inner wall of the support frame near the position above the toothed plate.

[0007] The lower docking assembly also includes a connecting rod on one side of the outer wall of the support frame. A handle is provided on the outer wall of the support frame away from the connecting rod. A through groove is provided on one side of the outer wall of the cable outlet tapping station near the handle. The handle is located on the outside of the cable outlet tapping station.

[0008] The bottom of the junction box body is provided with a plug, and the top of the outgoing line junction platform and the busbar trunking body are both provided with sockets. A rubber sealing ring is provided on the outer side of the top of the outgoing line junction platform near the socket.

[0009] Furthermore, the docking post and the docking groove are respectively provided with sliders and grooves that slide against each other, and four docking posts and four docking grooves are symmetrically arranged.

[0010] By adopting the above technical solution, the sliding fit ensures that the docking post is inserted vertically into the docking groove and that the insertion position of the docking post is stable.

[0011] Furthermore, the cross-section of the straight tooth groove is a right-angled triangle, and an inclined surface that fits the straight tooth groove is provided on one side of the outer wall of the tooth plate;

[0012] By adopting the above technical solution, and utilizing the cooperation of the straight tooth groove and the toothed plate, when the docking post moves downward, the straight tooth groove on the docking post pushes the toothed plate to rotate downward, ensuring that the docking post can move downward.

[0013] Furthermore, both ends of the connecting rod are provided with support frames, and a handle is provided on the outer side wall of one of the two support frames. The inside of the cable outlet junction box is provided with a cavity that allows the connecting rod to move horizontally.

[0014] By adopting the above technical solution, two adjacent support frames are connected by a connecting rod, and the two support frames are easily moved horizontally by a handle. The cavity design ensures smooth movement of the connecting rod.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes the unidirectional rotation and springback reset of the toothed plate to a horizontal state, allowing the toothed plate to be inserted into the straight tooth groove after the docking post is inserted into place. This achieves vertical positioning of the docking post within the groove, ensuring a firm and stable connection between the junction box body and the busbar trunking body. It prevents the connection from loosening or even drifting away due to vibration, thus reducing waterproof sealing and ensuring a secure connection. This also guarantees stable power distribution. The horizontally movable support frame allows the toothed plate to move away from and disengage from the straight tooth groove, facilitating the vertical removal of the junction box body and enabling disassembly between the junction box body and the busbar trunking body.

[0026] Reference Figure 1-5 This utility model embodiment proposes a busbar outlet junction box with a fire-resistant and waterproof structure, including a junction box body 1 and a busbar trunking body 2. The junction box body 1 is located above the busbar trunking body 2. The outer wall of the junction box body 1 is coated with a fireproof coating, and the junction box body 1 is made of metal to play a fireproof role. The top of the junction box body 1 is provided with an outlet junction platform 3, and the bottom of the junction box body 1 is provided with a docking post 41 in the upper docking assembly 4. A straight tooth groove 42 is opened on one side of the outer wall of the docking post 41.

[0027] The top of the outlet tapping station 3 is provided with a docking groove 51 for the lower docking assembly 5. The docking post 41 and the docking groove 51 are respectively provided with sliding blocks and grooves that slide against each other. Four docking posts 41 and four docking grooves 51 are symmetrically arranged. The sliding fit ensures that the docking post 41 is vertically inserted into the docking groove 51 and that the insertion position of the docking post 41 is stable. A guide post 52 is embedded in one inner wall of the docking groove 51. A support frame 54 is provided at one end of the guide post 52. A horizontal spring 53 is provided between one outer wall of the support frame 54 and one inner wall of the docking groove 51 near the outer side of the guide post 52. A toothed plate 55 is rotatably connected to one inner wall of the support frame 54. The cross-section of the straight toothed groove 42 is a right-angled triangle. An inclined surface that fits into the straight toothed groove 42 is provided on one outer wall of the toothed plate 55. The cooperation between the straight toothed groove 42 and the toothed plate 55 allows... When the docking post 41 moves downward, the straight tooth groove 42 on the docking post 41 pushes the tooth plate 55 to rotate downward, ensuring that the docking post 41 can move downward. A torsion spring 56 is provided at the rotation point of the tooth plate 55 and the support frame 54. A limit block 57 is provided on one inner wall of the support frame 54 near the position above the tooth plate 55. A connecting rod 58 is provided on one outer wall of the support frame 54, and a handle 59 is provided on the other outer wall of the support frame 54. Support frames 54 are provided at both ends of the connecting rod 58. A handle 59 is provided on the outer wall of one of the two support frames 54. The inside of the cable outlet tapping station 3 is provided with a cavity for the connecting rod 58 to move horizontally. The connecting rod 58 is used to connect two adjacent support frames 54, and the handle 59 is used to facilitate pulling the two support frames 54 to move horizontally. The cavity ensures that the connecting rod 58 moves smoothly.

[0028] A through groove 6 is provided on one side of the outer wall of the cable outlet junction box 3 near the outside of the handle 59, and the handle 59 is located on the outside of the cable outlet junction box 3.

[0029] The bottom of the junction box body 1 is provided with a plug 7, and the top of the outgoing cable junction platform 3 is provided with a socket 8 that matches the plug 7. A rubber sealing ring 9 is embedded in the top of the outgoing cable junction platform 3 near the outer side of the socket 8. The rubber sealing ring 9 is used to seal the connection between the junction box body 1 and the outgoing cable junction platform 3, so as to play a waterproof sealing role.

[0030] The specific implementation method is as follows: When connecting the junction box body 1 and the busbar trunking body 2, the connecting post 41 on the junction box body 1 is inserted into the connecting groove 51 on the outgoing junction platform 3. At this time, the plug 7 is inserted into the socket 8. As the junction box body 1 moves vertically toward the outgoing junction platform 3, the connecting post 41 is gradually inserted into the depth of the connecting groove 51. The connecting post 41 pushes the toothed plate 55, the toothed plate 55 rotates downward, the torsion spring 56 is compressed, and the rubber sealing ring 9 is squeezed between the junction box body 1 and the outgoing junction platform 3. When the connecting post 41 can no longer move downward, under the action of the rebound force of the torsion spring 56, the toothed plate 55 rotates upward. Under the limit of the limiting block 57, the toothed plate 55 is horizontally inserted into the straight tooth groove 42, thereby limiting the connecting post 41 and preventing the junction box body 1 and the busbar trunking body 2 from being firmly and tightly connected.

[0031] When it is necessary to disassemble the junction box body 1, push the handle 59 to move horizontally. Under the connection of the connecting rod 58, the support frame 54 moves horizontally. The toothed plate 55 on the support frame 54 moves away from and disengages from the straight tooth groove 42. At this time, after the docking column 41 loses its limit in the vertical direction, the junction box body 1 is pulled out in the vertical direction, realizing the disassembly between the junction box body 1 and the busbar trunking body 2.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
