Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the utility model pertains.
As shown in fig. 1, an embodiment of the present invention provides a power cable paying-off tensioning device that can be used to tension a cable during a paying-off process; the novel multifunctional desk lamp specifically comprises a base 100 and a pair of mounting racks 200, wherein the base 100 is provided with a mounting groove 110 for slidably mounting the two mounting racks 200; the two mounting racks 200 are oppositely arranged at intervals, and the lower ends of the mounting racks 200 are in sliding fit with the mounting groove 110; a reel 300 is rotatably arranged between the two mounting racks 200, cable trays 400 are fixed at two ends of the reel, a control mechanism for changing the distance between the two mounting racks 200 is arranged on the base 100, and when the distance between the two mounting racks 200 is reduced, the outer side surfaces of the cable trays 400 are in close contact with the inner side surfaces of the mounting racks 200.
In this embodiment, the mounting bracket 200 on the base 100 can relatively slide to realize the regulation to the interval, and the reel 300 that is located between two mounting brackets 200 is used for the coiling cable, and the interval that the cable need be taut in the unwrapping wire in-process between two mounting brackets 200 through control mechanism control reduces until cable dish 400 periphery and mounting bracket 200 medial surface in close contact with, and the unable rotation of cable conductor can make the cable taut, prevents the cable winding, improves the convenience of unwrapping wire operation. In this embodiment, it is understood that, in order to mount the reel 300, the reel 300 is provided at both ends thereof with rotation shafts engaged with the mounting bracket 200, and the rotation shafts may be passed through bearings provided in the mounting bracket 200, thereby reducing frictional force in rotation of the reel 300.
As mentioned above, the control mechanism is used to control the distance between the two mounting brackets 200; the control mechanism that provides in this embodiment is including locating guide bar 500 and adjusting screw 600 that is located mounting groove 110, guide bar 500 one end is inboard fixed with one of them mounting bracket 200, the other end and another mounting bracket 200 grafting cooperation, adjusting screw 600 one end is inboard rotatory with one of them mounting bracket 200 and is linked to each other, the other end level runs through another mounting bracket 200 and with mounting bracket 200 screw thread adaptation. Thus, when the technician rotates the adjusting screw 600, the mounting bracket 200 can move relatively close to or away from the mounting bracket 200, and the mounting bracket 200 can move stably along the mounting groove 110 under the action of the guide rod 500, so that the distance between the mounting brackets 200 can be adjusted. In order to facilitate the operation of the technician, the present embodiment is further provided with a hand-held rotating handle 700 at one end of the adjusting screw 600 penetrating through the mounting bracket 200. The hand-held handle 700 that rotates is set up and is conveniently rotated adjusting screw 600, can overlap on the hand-held handle 700 that rotates and establish the rotation cover, improves the comfort level of operation.
As shown in fig. 1, in order to prevent the cable tray 400 from rotating after the mounting bracket 200 contacts the cable tray 400, in this embodiment, anti-slip pads 800 are disposed on two opposite side surfaces of the cable tray 400 opposite to the mounting bracket 200, and elastic protrusions are disposed on outer side surfaces of the anti-slip pads 800. Thus, after the mounting bracket 200 is brought into contact with the cable drum 400, the anti-slip pads 800 can be brought into contact with each other, significantly increasing static friction under the action of the elastic protrusions, preventing the cable from being loosened due to rotation of the reel 300.
As shown in fig. 1, since the mounting bracket 200 slides along the mounting groove 110, in order to prevent the mounting bracket from shifting or falling off, the mounting groove 110 is provided with a falling-off preventing groove on a side wall thereof, and the falling-off preventing groove is slidably engaged with a falling-off preventing boss provided on an outer side of a lower end of the mounting bracket 200. Like this, anticreep groove and anticreep boss can mutually support, and the stability of improving the installation of mounting bracket 200 avoids mounting bracket 200 to topple over or drop. In order to reduce the friction force of the movement of the mounting bracket 200, the bottom wall of the mounting groove 110 is provided with a plurality of rotating rollers 900 arranged at intervals, and the rotating rollers 900 are in rolling fit with the lower end of the mounting bracket 200. The provision of the rotating roller 900 can further reduce the frictional force of the sliding of the mounting bracket 200.
In addition, when the technical staff was unwrapping wire, the condition of cable conductor wearing and tearing was easily caused in cable and ground friction, and this embodiment is equipped with output bracket 1000 at base 100 front end, and output bracket 1000 is last to be equipped with movable pulley 1100 of interval arrangement from top to bottom, forms the delivery outlet that supplies the cable to pass between two movable pulley 1100, output bracket 1000 corresponds movable pulley 1100 both ends and still is equipped with extension spring 1200, and extension spring 1200 both ends link to each other with movable pulley 1100 tip. Thus, when the cable is unwound, the cable can pass through the output port, and the movable pulley 1100 adjusts the distance in a self-adaptive manner according to the specification of the cable, so that the cable is prevented from being abraded.
As shown in fig. 1, in order to facilitate the transferring device, a self-locking universal wheel set 1300 is hinged to the outer side of the base 100. The universal wheel set 1300 can rotate, when the equipment is transferred, the equipment is rotated to the position where the equipment is matched with the ground in a rolling way, and when the equipment is not used, the equipment is rotated to the horizontal position; the convenience of equipment transfer is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
