Abstract

The utility model discloses a rope push-pull device which comprises a device body, a convolution arm, rope passing wheels, a rope fastening wheel, a rope fastening wheel passing clamp, a pull wire, a hand crank and a buffering tension spring. One end of the pull wire of the rope push-pull device is connected with 'a smoke flow control valve' through the buffering tension spring, and the other end of the pull wire of the rope push-pull device is connected with the rope fastening wheel through the rope passing wheels on the convolution arm. When the hand crank rotates in the counterclockwise direction, due to the action of the buffering tension spring, the pull wire produces elastic supporting force on the convolution arm, under the action of the elastic supporting force, the convolution arm rotates and moves counterclockwise with a center pivot as the center of a circle and pulls a pull rod of 'the smoke flow control valve' to conduct expansion movement, meanwhile, an indicating arrow of the convolution arm points to a corresponding scale of a main scale dial, therefore, the opening degree of 'the smoke flow control valve' at the smoke discharging position can be reflected accurately, and the smoke discharging speed and the smoke discharge amount are adjustable and controllable.

Description

Rope tensioner

Technical field

The utility model belongs to the rotary machine field, particularly a kind of rope tensioner.

Background technique

Burning bavin or burning coal is one of necessary form of northern China most areas people productive life, and the increasing that existing fume extractor can only be urged its fume emission speed and discharge amount mostly, general do not possess variation to the combination of cooking stove functional mapping, maximization that energy acquisition utilizes and to the function of the selection of fume emission speed and discharge amount, adjustment, control, for cook with cooking stove, heat up water, heating, flue of a kang insulation etc., its performance is particularly outstanding in the excessive situation of the power that pulls of fuel combustion speed and energy discharge excessive velocities and chimney.

Summary of the invention

The purpose of this utility model is can produce stable, external pull efficiently for " flue gas flow control valve " provides a kind of, and making " flue gas flow control valve " can be to choose at random, adjust and control between the 0-90 degree in the scope that is opened to sealing at the smoke exhaust port place.

The utility model is achieved through the following technical solutions: a kind of rope tensioner, comprise main body, backguy, wind, wire-crossing wheel, wire stretching wheel, wire stretching wheel is crossed card, convolution arm and buffering extension spring, it is characterized in that, described main body is by the sheetmetal manufacturing, described convolution arm is formed by the wire-crossing wheel merging by three limits in two regular hexagons, wire-crossing wheel is movably arranged on two and the turning point among the convolution arm, its turning point is provided with the graduation indication arrow, convolution one of arm by wire-crossing wheel be installed in the lower body part left side as in pivot, described wire stretching wheel is crossed card and is installed near the main body in wire stretching wheel edge.

Further, described lower body part is provided with the dial of 0-90 degree scope, and this scale can accurately reflect the degree that " flue gas flow control valve " opened in the smoke exhaust port place.

Further, the outer side surface of described wire stretching wheel is provided with the radiation helical teeth take its axle center as the center of circle of several projections, the external shaft of wire stretching wheel also is equipped with folding wind in the heart, and described wind can fold and be fixed on the main body when off working state.

Further, of described backguy links to each other with " flue gas flow control valve ", and the other end then links to each other with wire stretching wheel by wire-crossing wheel on wire drawing positioning device on the main body and the convolution arm.The pulling force of described buffering extension spring is greater than the elastic force of " flue gas flow control valve " upper spring.When the pulling force of described backguy acts on the pull bar of " flue gas flow control valve ", backguy then produces a kind of bullet support force for the convolution arm, this bullet support force acts on the arm body of convolution arm by wire-crossing wheel, the arm that causes circling round revolves between the 0-90 degree take middle pivot as the center of circle and moves, thereby reflects that accurately " flue gas flow control valve " is at the opening degree at smoke exhaust port place.

Embodiment

By following description to embodiment; to more help the public to understand the utility model; but the specific embodiment that the claimant can't be provided is considered as the restriction to technical solutions of the utility model, and any definition to parts or technical characteristics changes and/or overall structure is made form and immaterial conversion all should be looked the protection domain that technical solutions of the utility model are limited.

Be the variation of realization cooking stove function combined transformation and the maximization of energy acquisition utilization, overcome the defective of prior art, velocity of combustion and the energy discharge speed of comparatively ideal selection, adjustment and control fuel, the utility model is by following scheme implementation.

By reference to the accompanying drawings, the utility model comprises that main body, backguy, wind, wire-crossing wheel, wire stretching wheel, wire stretching wheel are crossed card, circle round arm and buffering extension spring.Main body of the present utility model is by the sheetmetal manufacturing, be provided with wire drawing positioning device 2 in upper left-hand, be provided with fixedly elastic buckles 14 of handle non-working condition in the middle of the top, upper right quarter stringing edge is attached with wire stretching wheel and crosses card 13, be rotatably installed in the lower left quarter of main body 3 by middle pivot 5 and wire-crossing wheel 4 arm 8 that will circle round, turning point and two of convolution arm all are equipped with wire-crossing wheel 4, the bottom of main body is provided with the convolution arm intercepting block 6 of projection, be provided with the dial 9 of 0-90 degree scope in the lower right of main body, the appropriate location of main body has some places and the mounting hole 15 that depends on thing and be connected, the upper right corner of main body is rotated wire stretching wheel 12 is installed, wind 11 is fixed on the wire stretching wheel, pull bar with " flue gas flow control valve " of buffering extension spring 1 links to each other, the other end is passed wire drawing positioning device 2 and is connected with wire stretching wheel 12 by 4 wire-crossing wheels 4 on the convolution arm, handle 11 drive wire stretching wheels 12 are done and are counterclockwise rotatablely moved when needed, power is delivered on " flue gas flow control valve " by backguy 10, meanwhile, 10 pairs of convolutions of backguy arm 8 can produce a kind of bullet support force, this bullet support force forces convolution arm 8 to do anticlockwise revolving around middle pivot 5 and moves, simultaneously, tuning drive gear 6 on the convolution arm 8 can point to the corresponding scale of dial and reflect the degree that " flue gas flow control valve " opened at the smoke exhaust port place, and then realizes the variation of cooking stove function combined transformation, the maximization that energy acquisition utilizes, flame mechanism and the energy discharge process of fuel also controlled in the rationalization of cooking range structure utilization at any time.
