Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a shockproof low-voltage bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute large power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. More than 90% of the main lines leading to the floors of the power distribution room in buildings with more than 12 floors use bus ducts; bus ducts are required to connect 630KVA transformers to distribution cabinets.

[0003] However, when installing a shockproof low-voltage bus duct with the above structure, the bus duct will have a certain vibration during operation, and the vibration will affect the connection of the bus duct installation, causing the connection to become loose, resulting in a loose installation. At the same time, the bus duct needs to be kept in a vertical state during installation to avoid affecting the installation on both sides and causing the horizontal and vertical state to be unable to be connected and installed. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a shockproof low-voltage bus duct. During installation, since the bus duct will have certain vibrations during operation, the vibrations will affect the connection of the bus duct installation, causing the connection to become loose, thereby resulting in a loose installation. At the same time, the bus duct needs to be kept in a vertical state during installation to avoid affecting the installation on both sides so as to prevent the horizontal and vertical installation from being affected, thereby resulting in the inability to dock and install the bus ducts.

[0005] To achieve the above-mentioned purpose, a shock-proof low-voltage bus duct is provided, comprising a bus duct body, and mounting blocks are symmetrically installed on the outer wall of the bus duct body, and the mounting blocks are symmetrically installed on one side of an L-plate, a limiting groove is provided on the inner wall of the L-plate, and a telescopic rod is installed on the inner wall of the limiting groove, a buffer plate is fixedly connected to the top of the telescopic rod, and a movable plate is symmetrically and movably sleeved on the surface of the telescopic rod, a first spring is fixedly connected to the bottom end of the buffer plate, and the first spring is fixed to the top of the movable plate, and a second spring is installed on the inner wall of the movable plate, a third spring is fixedly connected to the other side of the movable plate, and the third spring is movably sleeved on the surface of the telescopic rod.

[0006] Since the bus duct body will generate vibration during operation, the buffer plate will be pushed to slide into the limit groove, driving the telescopic rod to extend and retract, and then driving the first spring and the third spring to contract. When the first spring and the third spring contract to a certain extent, the movable plate symmetrically sleeved on the surface of the telescopic rod will also slide into the limit groove, and the second spring on the inner wall of the movable plate on both sides will contract. Therefore, the elasticity of the first spring, the second spring and the third spring can give a driving force to the buffer plate to offset the impact force generated by the vibration, thereby avoiding loosening of the installation due to vibration, which will reduce the stability of the installation.

[0007] According to the shockproof low-voltage bus duct, the outer wall of the movable plate is symmetrically fixedly connected with a first sliding block, and the first sliding block is movably sleeved inside the first sliding groove, and the first sliding groove is opened on the inner wall of the limiting groove.

[0008] According to the shockproof low-voltage bus duct, the limit blocks are symmetrically installed at the bottom end of the buffer plate, and the limit blocks are movably sleeved inside the groove, and the groove is opened at the top end of the cross bar.

[0009] According to the shockproof low-voltage bus duct, the inner wall of the groove is symmetrically provided with a second slide groove, and the second slide groove is movably sleeved with a second slider, and the second slider is symmetrically fixedly installed on both sides of the limit block.

[0010] According to the shockproof low-voltage bus duct, a through hole is opened at the top of the groove, a turning handle is movably sleeved at the bottom of the buffer plate, a connecting block is fixedly connected to the bottom of the turning handle, and a movable block is movably sleeved inside the connecting block.

[0011] According to the shockproof low-voltage bus duct, a third sliding groove is provided on the surface of the connection block, and a third sliding block is movably sleeved inside the third sliding groove, and the third sliding block is fixed on the surface of the movable block.

[0012] According to the shockproof low-voltage bus duct, a mounting plate is installed on one side of the cross bar.

[0013] By movably embedding the limit block into the groove, the buffer plate is pushed to movably fit on both sides of the bus duct body, and then the handle is turned to drive the connecting block to rotate, so that the movable block slides in the connecting block, slides from the inside to the outside, and is thus movably embedded in the through hole. The limit block is supported by the movable block to limit and fix the buffer plate. Flexible adjustment prevents the bus duct body from shifting, thereby ensuring the vertical stability of the bus duct body installation and avoiding the limit block from shifting during embedded installation, resulting in instability.

[0014] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Since the bus duct body 1 will generate vibration during operation, then the buffer plate 6 is pushed, driving the telescopic rod 5 to extend and retract, and the second springs 9 on the inner walls of the movable plates 7 on both sides are contracted, so that through the elasticity of the first spring 8, the second spring 9, and the third spring 10, a driving force can be given to the buffer plate 6 to offset the impact force generated by the vibration.

[0025] The outer wall of the movable plate 7 is symmetrically fixedly connected with a first slider 11, and the first slider 11 is movably sleeved inside the first slide groove 12, and the first slide groove 12 is opened on the inner wall of the limiting groove 4. When the movable plate 5 is pushed to slide in the limiting groove 2, the slider 9 slides in the slide groove 10, providing stability for the sliding of the movable plate 5, and also playing a role of limiting.

[0026] The limit block 13 is symmetrically installed at the bottom of the buffer plate 6, and the limit block 13 is movably sleeved in the groove 14, and the groove 14 is opened at the top of the cross bar 15. The limit block 13 and the cross bars 15 on both sides are embedded and installed, so that the cross bars 15 on both sides can be horizontally installed on both sides of the bus duct body 1, ensuring the vertical stability of the installation of the bus duct body 1.

[0027] The inner wall of the groove 14 is symmetrically provided with a second slide groove 16, and a second slider 17 is movably sleeved inside the second slide groove 16, and the second slider 17 is symmetrically fixedly installed on both sides of the limit block 13. When the limit block 13 is embedded with the cross bars 15 on both sides, the second slider 17 and the second slide groove 16 play a limiting role, preventing the limit block 13 from being offset during the embedded installation and causing instability.

[0028] A through hole 18 is provided at the top of the groove 14, a handle 19 is movably sleeved at the bottom of the buffer plate 6, and a connecting block 20 is fixedly connected to the bottom of the handle 19, and a movable block 21 is movably sleeved inside the connecting block 20.

[0030] A mounting plate 24 is installed on one side of the cross bar 15. Through the mounting plate 24, the bus duct body 1 can be fixedly installed on the wall.

[0031] Working principle: First, the bus duct body 1 will generate vibration during operation, and then push the buffer plate 6 to slide into the limit groove 4, driving the telescopic rod 5 to extend and retract, and then drive the first spring 8 and the third spring 10 to contract. When the first spring 8 and the third spring 10 contract to a certain extent, the movable plate 7 symmetrically sleeved on the surface of the telescopic rod 5 also slides into the limit groove 4, and the second springs 9 on the inner wall of the movable plate 7 on both sides contract, so that the buffer can be given by the elasticity of the first spring 8, the second spring 9, and the third spring 10. The plate 6 has a driving force to offset the impact force generated by the vibration. The limit block 13 is movably embedded in the groove 14 to push the buffer plate 6 to fit on both sides of the bus duct body 1. The handle 19 is turned to drive the connecting block 20 to rotate, so that the movable block 21 slides in the connecting block 20 from the inside to the outside, and is movably embedded in the through hole 18. The limit block 13 is supported by the movable block 21 to limit and fix the buffer plate 6. Flexible adjustment prevents the bus duct body 1 from being offset, and then the mounting plate 24 is installed on the wall.
