Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct with a long service life. Background Technique

[0002] A bus duct is a closed metal device composed of copper and aluminum busbars, used to distribute relatively large power to each component of a decentralized system, and has increasingly replaced wire and cable in indoor low-voltage power transmission trunk engineering projects.

[0003] Most of the existing bus ducts lack a protection structure for the end busbars at both ends. When the bus duct jolts or shakes during transportation, the two ends of the bus duct are extremely likely to collide with other objects, thus easily causing the deformation of the end busbars at both ends of the bus duct. Although some bus ducts are provided with a protection structure, when the bus duct is in use, the protection structure still needs to be removed, increasing the complexity of the installation of the bus duct. In view of this, we propose a bus duct with a long service life to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bus duct with a long service life to solve the problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A bus duct with a long service life, comprising:

[0006] A bus duct body, protection shells are arranged at both ends of the bus duct body, and the two protection shells are both slidably connected to the bus duct body. Fixed blocks are fixedly welded on the outer walls on both sides of the protection shell, slide bars are fixedly welded on both of the fixed blocks, a pair of sliding sleeves are fixedly welded on both side walls of the bus duct body, and the slide bars are slidably connected in the sliding sleeves. A limiting component is arranged on the sliding sleeve. The limiting component includes a limiting rod, the limiting rod is slidably connected to the sliding sleeve, a pulling plate is fixedly welded at the outer end of the limiting rod, a tension spring is sleeved on the limiting rod, and the two ends of the tension spring are respectively fixedly connected to the sliding sleeve and the pulling plate. A limiting groove adapted to the limiting rod is opened on the slide bar.

[0007] Preferably, a first insertion groove is opened on the inner wall of one of the protection shells.

[0008] Preferably, a second insertion groove is opened on the outer wall of the other protection shell.

[0009] Preferably, a sealing ring is fixedly installed on the inner wall of the first insertion groove.

[0010] Preferably, protective covers are arranged at the ends of the two protection shells, and the protective covers are adhered to the protection shells through transparent tape.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model can protect the wire rows at both ends of the bus duct by providing a protective shell and a protective cover, thereby preventing the two ends of the bus duct from easily colliding with other objects when the bus duct is bumped or shaken during transportation and transfer, thereby easily causing the wire rows at both ends of the bus duct to deform, thereby greatly improving the service life of the bus duct;

[0013] 2. When the utility model is in use, when the wire rows at the ends of two bus ducts are butt-jointed, the limit rod can be pulled to disengage the limit rod from the limit groove of the slide rod, thereby sliding the protective shell onto the bus duct body to expose the wire rows at both ends of the bus duct, facilitating the connection of the wire rows. After the wire rows are connected, the two protective shells can be slid and butt-jointed to form a protective box, thereby achieving the effect of protecting the connected wire rows, and having a good dustproof and waterproof effect.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1-3 The utility model provides a technical solution: a bus duct with a long service life, comprising:

[0020] Busbar trunking body 1, protective shells 2 are arranged at both ends of the busbar trunking body 1, and the two protective shells 2 are both slidably connected to the busbar trunking body 1. Fixed blocks 3 are fixedly welded on the outer walls on both sides of the protective shell 2, slide bars 4 are fixedly welded on the two fixed blocks 3, a pair of sliding sleeves 5 are fixedly welded on both side walls of the busbar trunking body 1, and the slide bars 4 are slidably connected in the sliding sleeves 5. A limiting component is arranged on the sliding sleeve 5. The limiting component includes a limiting rod 6, the limiting rod 6 is slidably connected to the sliding sleeve 5, a pulling plate 7 is fixedly welded to the outer end of the limiting rod 6, a tension spring 8 is sleeved on the limiting rod 6, and the two ends of the tension spring 8 are respectively fixedly connected to the sliding sleeve 5 and the pulling plate 7. A limiting groove adapted to the limiting rod 6 is formed on the slide bar 4.

[0021] A first insertion groove 9 is formed on the inner wall of one of the protective shells 2.

[0022] A second insertion groove 10 is formed on the outer wall of the other protective shell 2. The first insertion groove 9 and the second insertion groove 10 formed facilitate the insertion and cooperation of the two protective shells 2, so that the two protective shells 2 are butted to protect the connected busbar connectors.

[0023] A sealing ring 11 is fixedly installed on the inner wall of the first insertion groove 9. The sealing ring 11 can improve the sealing performance when the two protective shells 2 are butted, and has a good waterproof and dustproof effect.

[0024] Protective covers 12 are arranged at the ends of the two protective shells 2. The protective covers 12 are adhered to the protective shells 2 through transparent tapes. The protective covers 12 can cover and protect the protective shells 2, and can cooperate with the protective shells 2 during transportation to comprehensively protect the busbar ends.

[0025] Working principle: The utility model can protect the busbars at both ends of the busbar trunking through the arranged protective shells 2 and protective covers 12, avoiding the problem that when the busbar trunking bumps or shakes during transportation and transfer, the two ends of the busbar trunking are extremely easy to collide with other objects, thus easily deforming the busbars at both ends of the busbar trunking, greatly improving the service life of the busbar trunking. When in use, when the busbars at the two ends of the busbar trunking are butted, the limiting rod 6 can be pulled to make the limiting rod 6 disengage from the limiting groove of the slide bar 5, so as to slide the protective shell 2 onto the busbar trunking body 1, exposing the busbars at both ends of the busbar trunking for convenient connection of the busbars. After the busbars are connected, the two protective shells 2 can be slid and butted to form a protective box, realizing the effect of protecting the connected busbars, and having a good dustproof and waterproof effect.
