Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a high-strength improved bus duct. Background Art

[0002] Bus duct is a closed metal device, which is mainly 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 projects. Many large standardized factories and high-rise buildings are increasingly using low-voltage bus ducts as power transmission and distribution devices.

[0003] The existing bus duct is generally composed of an outer shell and several groups of copper bars. Since the ends of the copper bars are directly extended out of the shell, when the bus duct needs to be transported or moved, it is very easy for the copper bar ends of the bus duct to collide with other objects and be worn or bent or broken, which can easily cause damage to the bus duct. Utility Model Content

[0004] The utility model aims to provide a high-strength improved bus duct to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-strength improved bus duct, comprising a bus duct body and protective shells symmetrically arranged on the left and right sides of a port of the bus duct body, wherein the left and right sides of the port of the bus duct body are symmetrically provided with driving rods rotatably connected thereto, one end of the driving rod close to the bus duct body is fixedly connected with a driving gear, and the end of the driving rod away from the driving gear is provided with a driving handle, and installation grooves are symmetrically opened on both sides of the upper and lower end surfaces of the port of the bus duct body, and a pulley with one end extending to the outside of the installation groove is installed in the installation groove;

[0007] The protective shell includes a driving plate, a limiting groove is formed through the driving plate and can limit the forward and backward displacement of the driving rod. A driving rack that matches the driving gear is provided on the inner side wall of the driving plate at the top of the limiting groove. The upper and lower sides of the driving plate are folded inward to form a symmetrical mounting plate. A track rod that matches the pulley is provided on the inner side wall of the mounting plate.

[0008] As a further description of the present invention, first reinforcement strips are symmetrically provided at both ends of the inner side wall of the driving plate.

[0009] As a further description of the present invention, second reinforcement strips integrally formed with the first reinforcement strips are symmetrically arranged on both sides of the inner end surface of the mounting plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] When the bus duct body needs to be transported or moved, the staff turns the driving handle to drive the driving gear to rotate, and the driving gear continuously meshes with the driving rack on the inner wall of the protective shell to transmit motion and power, thereby driving the driving plate and the mounting plate to produce linear motion. At the same time, the track rod on the inner wall of the mounting plate is in rolling contact with the pulley on the bus duct body, thereby reducing the friction, making it easier, more convenient and more stable for the protective shell to move outside the port of the bus duct body until the protective shell completely wraps the copper busbar end, thereby realizing protection of the copper busbar end. The utility model has a simple structure and is easy to operate. It can facilitate the staff to effectively protect the copper busbar at the end of the bus duct body when transporting or moving the bus duct body, thereby avoiding the copper busbar end of the bus duct body from colliding with other objects and being worn or bent or broken, thereby improving the safety and reliability of the use of the bus duct body and ensuring the normal operation of the bus duct body.

[0019] Example

[0020] Combination Figure 1-4 A high-strength improved bus duct shown in the figure includes a bus duct body 1 and a protective shell 2 symmetrically arranged on the left and right sides of the port of the bus duct body 1. Through the arrangement of the protective shell 2, it is convenient for the staff to effectively protect the copper busbar at the end of the bus duct body 1 when transporting or moving the bus duct body 1, thereby avoiding the copper busbar end of the bus duct body 1 from colliding with other objects and being worn or bent or broken, thereby improving the safety and reliability of the use of the bus duct body 1 and ensuring the normal operation of the bus duct body 1.

[0021] like Figure 3 The bus duct body 1 shown in the figure has drive rods 101 symmetrically provided on both sides of the port of the bus duct body 1 for rotation therewith, one end of the drive rod 101 close to the bus duct body 1 is fixedly connected to a drive gear 102, and the end of the drive rod 101 away from the drive gear 102 is provided with a drive handle 103, and installation grooves 104 are symmetrically provided on both sides of the upper and lower end surfaces of the port of the bus duct body 1, and a pulley 105 with one end extending to the outside of the installation groove 104 is installed in the installation groove 104.

[0022] like Figure 4The protective shell 2 shown in the figure comprises a driving plate 201, and a limiting groove 202 is formed on the driving plate 201 to limit the front and rear displacement of the driving rod 101. By setting the limiting groove 202, the displacement of the driving plate 201 can be guided and limited. A driving rack 203 matching the driving gear 102 is provided on the inner side wall of the driving plate 201 at the top of the limiting groove 202. Both upper and lower sides of the driving plate 201 are folded inward to form a symmetrical installation. Plate 204, the inner wall of the mounting plate 204 is provided with a track rod 205 matched with the pulley 105, the circumferential surface of the pulley 105 has a groove, when the mounting plate 204 is displaced, the track rod 205 is driven to slide in the groove of the pulley 105, the friction between the track rod 205 and the pulley 105 will cause the pulley 105 to rotate around the central axis, based on the principle of rolling contact, thereby reducing the friction, making the displacement of the protective shell 2 on the outside of the port of the bus duct body 1 easier, more convenient and smoother.

[0023] A further optimization scheme is that the first reinforcement strips 206 are symmetrically provided at both ends of the inner wall of the driving plate 201, and the second reinforcement strips 207 integrally formed with the first reinforcement strips 206 are symmetrically provided on both sides of the inner end surface of the mounting plate 204. Through the arrangement of the first reinforcement strips 206 and the second reinforcement strips 207, the overall strength and service life of the protective shell 2 are improved.

[0024] The working principle of the high-strength improved bus duct of the utility model is as follows:

[0025] When the bus duct body 1 needs to be transported or moved, the staff rotates the driving handle 103 to drive the driving gear 102 to rotate, and the driving gear 102 continuously meshes with the driving rack 203 on the inner wall of the protective shell 2 to transmit motion and power, thereby driving the driving plate 201 and the mounting plate 204 to produce linear motion. At the same time, the track rod 205 on the inner wall of the mounting plate 204 rolls with the pulley 105 on the bus duct body 1, thereby reducing the friction force, making the displacement of the protective shell 2 outside the port of the bus duct body 1 easier, more convenient and more stable, until the protective shell 2 completely wraps the copper busbar end, thereby achieving the copper busbar end. Protection, when two adjacent bus duct bodies 1 are installed and connected, it is only necessary to reverse the above operation to reset the protective shell 2, and the reset protective shell 2 is flat and beautiful at the port of the bus duct body 1, and does not affect the subsequent installation and connection of the bus duct body 1. The utility model has a simple structure and is easy to operate. It can be convenient for the staff to effectively protect the copper busbar at the end of the bus duct body 1 when transporting or moving the bus duct body 1, thereby avoiding the copper busbar end of the bus duct body 1 from colliding with other objects and being worn or bent or broken, thereby improving the safety and reliability of the use of the bus duct body 1 and ensuring the normal operation of the bus duct body 1.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
