Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct that can be quickly spliced. Background Art

[0002] Modern high-rise buildings and large workshops often require enormous amounts of electrical energy. To cope with the hundreds or even thousands of amperes of current required by these massive loads, safe and reliable transmission equipment is essential. Busbar ducts, as a highly efficient current distribution device, are particularly well-suited for the economical and rational wiring needs of high-rise buildings and large-scale factories. They have become an indispensable wiring method for the electrical equipment and power systems of high-rise buildings and factories. When using busbar ducts for power transmission and distribution, multiple busbars are often spliced ​​together to extend their length. Connectors are typically installed at the splicing points, and cover plates are required to shield these connectors to prevent dust and moisture from entering the connectors, potentially causing oxidation or leakage.

[0003] Chinese patent publication number CN219918341U, publication date 20231027, discloses an improved bus duct with efficient connection, including a bus duct shell and a connecting component that is detachably arranged between two adjacent bus duct shells. The connecting component includes an upper connecting plate and a lower connecting plate with a U-shaped structure. A first connecting plate is symmetrically provided on both sides of the bottom of the upper connecting plate. A fixing block is provided on the bottom end surface of the first connecting plate, and a limit block with a T-shaped structure is symmetrically provided on both sides of the fixing block.

[0004] For example, the above-mentioned existing bus duct is configured to cooperate with the fixing block and the fixing groove with the limit block and the limit groove, so that the upper connecting plate and the lower connecting plate can be clamped and fixed, and the fastening bolts are inserted into the first mounting hole and the second mounting hole in turn to further fix the two connecting plates. In the specific implementation, the entire splicing process not only requires the combination of the bus duct shell, but also the combination of the limit block and the limit groove, and finally the combination of the connection assembly must be realized through the locking rod. The operation is relatively cumbersome, so it is urgent to propose a corresponding bus duct that can be quickly spliced ​​to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and to provide a bus duct that can be quickly spliced.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A bus duct that can be quickly spliced ​​includes a bus duct shell one and a bus duct shell two. The horizontal ends of the bus duct shell one and the bus duct shell two are respectively fixedly connected with a convex frame two and a convex frame one. A combination frame is sleeved on the outer sides of the adjacent convex frame one and the convex frame two. The top of the combination frame is fixedly connected to the convex frame one and the convex frame two through two groups of locking rods, and the top of the combination frame is provided with a limiting assembly for axially limiting the two groups of locking rods.

[0008] Preferably, the limiting assembly includes two groups of rubber blocks, both groups of rubber blocks are interference fit with the inner surface wall of the top of the combination frame, and the two groups of rubber blocks are respectively in contact with the tops of the two groups of locking rods.

[0009] Preferably, the two groups of locking rods are respectively passed through the two groups of through-holes 1 and are arranged on the top of the combination frame, and the tops of the convex frame 1 and the convex frame 2 are both provided with screw holes matching the locking rods.

[0010] Preferably, transverse grooves are provided at the longitudinal ends of the bus duct housing 1 and the bus duct housing 2.

[0011] Preferably, a rubber pad is fixed to the inner surface wall of the combination frame, the inner surface wall of the rubber pad abuts against the outer surface walls of the convex frame 1 and the convex frame 2, and the rubber pad is provided with two groups of through holes 2 matching the locking rods.

[0012] Preferably, the bus duct housing 1 and the convex frame 2, as well as the bus duct housing 2 and the convex frame 1 are all integrally formed.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present application, the convex frame 1 on the bus duct shell 1 and the convex frame 2 on the bus duct shell 2 are simultaneously combined with the interior of the combination frame until the bus duct shell 1 and the bus duct shell 2 are both in contact with the combination frame. At this time, the two groups of through-holes 1 and 2 are exactly aligned with the screw holes, and the combination frame is fixed to the convex frame 1 and the convex frame 2 by two groups of locking rods, thereby realizing the overall splicing of the bus duct, ensuring the overall stability of the bus duct, and improving the speed of the bus duct splicing. At the same time, the rubber pad integrated in the combination frame maintains a fit with the convex frame 1 and the convex frame 2, thereby ensuring the tightness of the combination of the bus duct shell 1 and the bus duct shell 2.

[0015] 2. In this application, after completing the splicing of the bus duct shell and the bus duct shell, the two sets of rubber blocks can be stuffed into the top of the combination frame. The interference fit method ensures that the position of the two sets of rubber blocks themselves is stable. The two sets of rubber blocks are respectively abutted against the top of the two sets of locking rods, thereby limiting the loosening of the two sets of locking rods through friction.

[0024] A bus duct that can be quickly spliced ​​includes a bus duct housing 1 and a bus duct housing 2. The horizontal ends of the bus duct housing 1 and the bus duct housing 2 are respectively fixedly connected to a protruding frame 2 8 and a protruding frame 1 4. The outer sides of the adjacent protruding frames 1 4 and 2 are sleeved with a combination frame 3. The top of the combination frame 3 is fixedly connected to the protruding frame 1 4 and the protruding frame 2 8 via two sets of locking rods 9. The top of the combination frame 3 is provided with a limit assembly for axially limiting the two sets of locking rods 9.

[0025] The convex frame 1 on the bus duct shell 1 and the convex frame 2 on the bus duct shell 2 2 are simultaneously combined into the interior of the combination frame 3 until the bus duct shell 1 and the bus duct shell 2 2 are both in contact with the combination frame 3. At this time, the two groups of through-holes 11 and through-holes 12 are exactly aligned with the screw holes 5. The combination frame 3 is fixed to the convex frame 1 4 and the convex frame 2 8 through two groups of locking rods 9, thereby realizing the overall splicing of the bus duct, ensuring the overall stability of the bus duct, and improving the rapidity of the bus duct splicing. At the same time, the rubber pad 10 integrated in the combination frame 3 maintains a fit with the convex frame 1 4 and the convex frame 2 8, thereby ensuring the tightness of the combination of the bus duct shell 1 and the bus duct shell 2 2.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the limit assembly includes two groups of rubber blocks 7. Both groups of rubber blocks 7 are interference fit with the inner surface wall of the top of the combination frame 3. The two groups of rubber blocks 7 are respectively abutted against the top of the two groups of locking rods 9. After the bus duct housing 1 and the bus duct housing 2 2 are spliced ​​together, the two groups of rubber blocks 7 can be inserted into the top of the combination frame 3. The interference fit ensures that the positions of the two groups of rubber blocks 7 themselves are stable. The two groups of rubber blocks 7 are respectively abutted against the top of the two groups of locking rods 9, thereby limiting the loosening of the two groups of locking rods 9 through friction.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, two sets of locking rods 9 are respectively passed through two sets of through-holes 11 to pass through the top of the combination frame 3, and screw holes 5 matching the locking rods 9 are provided on the tops of the convex frame 4 and the convex frame 2 8. The bus duct shell 1 and the bus duct shell 2 2 are both in contact with the combination frame 3. At this time, the two sets of through-holes 11 and the through-holes 12 are exactly aligned with the screw holes 5. The combination frame 3 is fixed to the convex frame 4 and the convex frame 2 8 through the two sets of locking rods 9. The longitudinal ends of the bus duct shell 1 and the bus duct shell 2 2 are both provided with transverse grooves 6 to ensure good heat dissipation performance of the bus duct.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, a rubber pad 10 is fixed to the inner wall of the combination frame 3, and the inner wall of the rubber pad 10 is in contact with the outer wall of the convex frame 1 4 and the convex frame 2 8, and the rubber pad 10 is provided with two groups of through holes 12 matching the locking rod 9. The rubber pad 10 maintains a fit with the convex frame 1 4 and the convex frame 2 8, thereby ensuring the tightness of the combination of the bus duct shell 1 and the bus duct shell 2 2. The bus duct shell 1 and the convex frame 2 8, as well as the bus duct shell 2 2 and the convex frame 1 4, are all integrally formed, ensuring the overall structural strength of the bus duct.

[0029] Working principle: The convex frame 1 on the bus duct shell 1 and the convex frame 2 on the bus duct shell 2 are simultaneously combined into the interior of the combination frame 3 until the bus duct shell 1 and the bus duct shell 2 are both in contact with the combination frame 3. At this time, the two sets of through-holes 11 and 12 are exactly aligned with the screw holes 5. The combination frame 3 is fixed to the convex frame 1 4 and the convex frame 2 8 through two sets of locking rods 9, thereby realizing the overall splicing of the bus duct, ensuring the overall stability of the bus duct and improving the speed of bus duct splicing. At the same time, the rubber pad 10 integrated into the combination frame 3 maintains a fit with the convex frame 1 4 and the convex frame 2 8, thereby ensuring the tightness of the combination of the bus duct housing 1 and the bus duct housing 2 2. After the bus duct housing 1 and the bus duct housing 2 2 are spliced ​​together, the two sets of rubber blocks 7 can be stuffed into the top of the combination frame 3. The interference fit ensures the stability of the position of the two sets of rubber blocks 7. The two sets of rubber blocks 7 are respectively in contact with the top of the two sets of locking rods 9, thereby limiting the loosening of the two sets of locking rods 9 through friction.
