Detailed Description

Although the adjustable bus duct proposed in the above patent can be stretched to some extent, when stretching, an excessive stretching force may occur, which may cause the internal circuit element to break without bearing the tension, thereby damaging the bus duct. Therefore, there is a need for a stretch bus duct that loosens the internal conductors a certain length prior to stretching the bus duct, thereby preventing the internal conductors from being torn off during the stretching of the bus duct.

Examples

Referring to fig. 1-7, the embodiment provides a tensile bus duct, which comprises a housing 10, wherein the housing 10 comprises a main housing 11 and an auxiliary housing 12, an adjusting assembly 20 is arranged between the main housing 11 and the auxiliary housing 12, a power assembly 30 is arranged in the auxiliary housing 12, a wire winding assembly 40 is sleeved at one end of the periphery of the power assembly 30, and a fixing assembly 50 is arranged at one end of the power assembly 30 away from the wire winding assembly 40; the adjusting component 20 is used for adjusting the distance between the main shell 11 and the auxiliary shell 12, the power component 30 is used for driving the wire collecting component 40 to rotate, the fixing component 50 is used for fixing the wire collecting component 40 in the rotated original position, and the wire collecting component 40 is used for automatically collecting the pulled wire.

The working principle is as follows:

when the device is used, if the bus duct needs to be lengthened, firstly, a power supply is connected, the power component 30 drives the wire collecting component 40 to rotate, so that the internal winding wires are loosened by a certain length, then the rotated position of the wire collecting component 40 is fixed through the fixing component 50 to prevent the wire collecting component from rotating, then the auxiliary shell 12 is pulled out of the main shell 11 through the adjusting component 20, and if the bus duct needs to be shortened, firstly, the auxiliary shell 12 is inserted into the main shell 11, then the fixing component 50 is loosened, the wire collecting component 40 drives the power component 30 to rotate, and the loosened wires are wound back onto the wire collecting component 40.

In order to change the length of the bus duct, the adjusting assembly 20 comprises a sleeve 21 arranged at one end of the main shell 11 and a plug tube 22 arranged at one end of the auxiliary shell 12, a plurality of pairs of mounting grooves 23 are formed in the inner side wall of the sleeve 21, clamping springs 25 are arranged in each mounting groove 23, one end of each clamping spring 25 is fixedly connected with the inner side wall of each mounting groove 23, one end of each clamping spring 25, which is far away from each mounting groove 23, is fixedly connected with a clamping block 26, and a pair of clamping grooves 24 are formed in the outer side wall of the plug tube 22; when the bus duct needs to be shortened, the inserting cylinder 22 is inserted into the sleeve 21, during the period, the clamping groove 24 presses the clamping block 26 far away from the main shell 11 into the mounting groove 23, meanwhile, the clamping spring 25 is compressed, and after the bus duct distance is adjusted, the clamping block 26 at the corresponding position is pushed into the mounting groove 23 under the restoring force of the clamping spring 25; conversely, when the bus duct needs to be elongated, the socket 22 is pulled out of the sleeve 21.

Considering the reason that the wires need to be loosened for a certain length in advance before the length of the bus duct is adjusted, the power assembly 30 comprises a rotating rod 31 rotatably connected to the side wall of the auxiliary shell 12, one end of the rotating rod 31 is provided with a motor 32, the motor 32 is fixedly connected to the outer side wall of the auxiliary shell 12, and an output shaft of the motor 32 is fixedly connected with the rotating rod 31; after the power is turned on, the motor 32 drives the rotating rod 31 to rotate, so that the wire wound on the wire winding assembly 40 is loosened by a length for buffering.

Since the loose wire needs to be automatically retracted, the wire winding assembly 40 includes a torsion spring 41 sleeved on the periphery of the rotating rod 31, and a winding drum 42 is sleeved on the periphery of the torsion spring 41; when the bus duct needs to be machined for shortening, the fixing assembly 50 is loosened, and the winding drum 42 is driven to rotate under the restoring force of the torsion spring 41 which is tensioned in advance, so that the wire is retracted.

In order to prevent the bobbin 42 from being rotated by the torsion spring 41 after a section of wire is loosened, the fixing assembly 50 comprises a pawl 52 arranged at the periphery of the rotating rod 31, the pawl 52 is coaxially connected with the rotating rod 31, a plurality of ratchet wheels 51 are arranged at the periphery of the pawl 52, and the ratchet wheels 51 are rotationally connected with the inner wall of the bobbin 42; when the driving member rocker swings counterclockwise, the driving pawl 52 is inserted into the tooth slot of the ratchet wheel 51, pushing the ratchet wheel 51 to rotate through an angle, and at this time, the stopping pawl slides on the tooth back of the ratchet wheel 51. When the driving member rocker swings clockwise, the pawl prevents the ratchet wheel 51 from rotating in a clockwise direction, and the driving pawl 52 is able to slide over the back of the ratchet wheel 51 teeth, so the ratchet wheel 51 is stationary. Thus, the ratchet 51 is intermittently moved in one direction as the rocker is continuously reciprocated.

When the stretching bus duct in the embodiment is specifically used, if the device needs to stretch the bus duct, firstly, the power supply is switched on to enable the power component 30 to drive the wire collecting component 40 to rotate, so that the internal winding wires are loosened by a certain length, specifically, after the power supply is switched on, the motor 32 drives the rotating rod 31 to rotate, and the wires wound on the wire collecting component 40 are loosened by a length for buffering; conversely, when the bus duct needs to be elongated, the plug 22 is pulled out of the sleeve 21; then, the rotated position of the wire winding assembly 40 is fixed by the fixing assembly 50, so that the wire winding assembly is prevented from rotating, specifically, when the driving member rocker swings anticlockwise, the driving pawl 52 is inserted into the tooth slot of the ratchet wheel 51, the ratchet wheel 51 is pushed to rotate by an angle, and at the moment, the locking pawl slides on the tooth back of the ratchet wheel 51. When the driving member rocker swings clockwise, the pawl prevents the ratchet wheel 51 from rotating in a clockwise direction, and the driving pawl 52 is able to slide over the back of the ratchet wheel 51 teeth, so the ratchet wheel 51 is stationary. Thus, when the rocker is continuously reciprocated, the ratchet 51 is intermittently moved in one direction; the auxiliary shell 12 is then pulled out of the main shell 11 by the adjusting assembly 20, and if the bus duct needs to be shortened, firstly, the auxiliary shell 12 is inserted into the main shell 11, then the fixing assembly 50 is loosened, the wire collecting assembly 40 drives the power assembly 30 to rotate, the loosened wires are wound back onto the wire collecting assembly 40, specifically, when the bus duct needs to be shortened, the fixing assembly 50 is loosened, the winding drum 42 is driven to rotate under the action of the restoring force of the torsion spring 41 which is tensioned in advance, and the wires are accordingly collected.
