Abstract
The utility model relates to a tensile-force adjusting device, which comprises a bracket, sliding rods and pulleys, wherein the two metallic sliding rods are vertically arranged on a pedestal of the bracket, a movable fixed baffle plate is installed between the metallic sliding rods, the front end of the fixed baffle plate is connected with one pulley, and the other pulley is simultaneously installed at the top end of the bracket; and two springs are respectively sleeved on the sliding rods at the upper side and the lower side positioned at the positions of the fixed baffle plate. The utility model has the beneficial effects that: an upper-lower double-pulley structure is adopted, a certain tensile force can be constantly kept in the winding and unwinding processes, the phenomena of wire-coil looseness, non-uniform cable-winding density and the like in the winding process can be avoided, and the wire-winding or wire-unwinding efficiency can be improved.
Description
Technical field
The utility model 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.
The utility model content
At above defective, the purpose of this utility model provides 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 utility model 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 described in the utility model 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 utility model is described in further detail below.
Fig. 1 is the structural representation of the described tension adjusting device of the utility model embodiment;
Fig. 2 is the sheave segment partial schematic diagram of the described tension adjusting device of the utility model embodiment.
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 described in the utility model, 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.
