Abstract

The invention provides a tension adjusting device which comprises a bracket, two slide rods and two slide wheels, wherein the base of the bracket is vertically provided with the two metal slide rods, a movable fixed baffle plate is arranged between the two metal slide rods, the front end of the fixed baffle plate is connected with one slide wheel, and the top end of the bracket is simultaneously provided with the other slide wheel; and the two slide rods which are arranged at the upper side and the lower side of the position of the fixed baffle plate are respectively sheathed with a spring. The tension adjusting device has the beneficial effects that by adopting a top and bottom double-slide wheel structure, a certain tension can be constantly kept during winding and unwinding a cable, the phenomena that a cable coil is loosened, the cable winding thickness is uneven and the like during winding can be avoided, the cable winding efficiency or the wire unwinding efficiency can be improved.

Description

A kind of tension adjusting device

Technical field

The present invention relates to a kind of tension adjusting device.

Background technology

Existing cable needs constant maintenance certain force of strain in the folding and unfolding process, its drum produces that loosening, cable twines that density unevenness is even to avoid in winding process, take-up or the lower problem of unwrapping wire efficient, simultaneously so that better fit volume unwrapping wire equipment; Therefore the part same device can adopt some pulley combinations, by twining in regular turn of cable by realizing the adjustment of tension force, but pulley position is provided with reasonable inadequately, and the cable canoe is comparatively loaded down with trivial details, the cable outlet direction is unfixing, therefore exists certain defective.

Summary of the invention

At above defective, the purpose of this invention is to provide a kind ofly can rationally adjust the cable degree of tightness, keep cable density evenly, improve the tension adjusting device of retractable cable efficient, to solve many deficiencies of prior art.

For achieving the above object, the present invention is achieved through the following technical solutions:

A kind of tension adjusting device comprises support, slide bar, pulley, and two metal slide bars vertically are set on the base of support, and mobilizable fixed dam is installed between the described slide bar, and this fixed dam front end connects pulley and cantilever tip is installed a pulley simultaneously; Be positioned at the fixed dam position and be with spring respectively on the slide bar of both sides up and down.

The beneficial effect of tension adjusting device of the present invention is: adopt sister block structure up and down, can constant maintenance certain force of strain in the folding and unfolding process, phenomenons such as its drum generation is loosening in winding process, cable winding density unevenness is even can be avoided, take-up or unwrapping wire efficient can be improved.

Description of drawings

According to embodiment and accompanying drawing the present invention is described in further detail below.

Fig. 1 is the structural representation of the described tension adjusting device of the embodiment of the invention;

Fig. 2 is the sheave segment partial schematic diagram of the described tension adjusting device of the embodiment of the invention.

Among the figure:

1, support; 2, slide bar; 3, pulley; 4, fixed dam; 5, spring; 6, base; 7, wire casing.

The specific embodiment

Shown in Fig. 1-2, tension adjusting device of the present invention, comprise support 1, slide bar 2, pulley 3, two metal slide bars 2 vertically are set on the base 6 of described support 1, mobilizable fixed dam 4 is installed between this metal slide bar 2, and these fixed dam 4 front ends connect pulley 3 and a pulley 3 is installed on support 1 top simultaneously; Be positioned at fixed dam 4 positions and be with up and down spring 5 automatic compensation tension force when passing on the both sides slide bar 2 respectively, evenly offer some wire casings 7 on the outside cylinder of described pulley 3 to strengthen vertical elastic force of pulley 3, to be convenient to cable simultaneously.By this pulley structure setting can be in the folding and unfolding process can constant maintenance certain force of strain, can avoid in winding process its drum to produce loosening, cable and twine phenomenons such as density unevenness is even, can improve take-up or unwrapping wire efficient.

Claims (2)

1. tension adjusting device, comprise support (1), slide bar (2), pulley (3), on the base (6) of support (1) two metal slide bars (2) are set vertically, it is characterized in that: mobilizable fixed dam (4) is installed between the described slide bar (2), and this fixed dam (4) front end connects pulley (3) and a pulley (3) is installed on support (1) top simultaneously; Be positioned at fixed dam (4) position and be with spring (5) respectively on the both sides slide bar (2) up and down.
