Abstract

The utility model relates to a steel cable capstan. A metal reed is used as an action mechanism for controlling a claw sheet to be in a stretching state or in a backward retraction state. Due to the fact that the metal reed has favorable elastic tension in a press direction or a push direction, more assured push force can be provided for the claw sheet to push a ratchet wheel to rotate and to be twisted. In addition, the ratchet wheel on a single side is improved into the ratchet wheel, both sides of which are simultaneously pushed; thus, the utility model is helpful to the balance and the stability of the twist and the pull of a steel cable.

Description

Steel cable capstan

The utility model relates to a kind of cable wire strand and draws device.

It is that a kind of ratchet strand of utilizing is drawn cable wire and the laborsaving apparatus of the article of can slinging that the cable wire strand is drawn device.As shown in Figure 4, armed lever A front end is established a calvus B, this calvus B cooperates the setting of ratchet profile of tooth, be provided with between armed lever A and calvus B that a wound spring controls that calvus B upholds or after contract, when calvus B after when contracting state, the rotation of ratchet C and calvus B are irrelevant, and this is that to loosen cable wire be to hang the state that article are prepared; When calvus B is stretched condition, can make armed lever A pull in the stroke last, the turn strand is drawn by means of calvus B promotes ratchet C; Armed lever A is in pressing down stroke in addition, and calvus B can throw off with ratchet C, thinks that pulling stroke on the next stage prepares.

It should be noted that because the wound spring intensity that connects between armed lever A and calvus B is relatively poor, promptly be easy to generate permanent deformation after use a period of time, and then cause the loosening slippage of calvus B when promoting ratchet D, and can't reach the purpose that strand is drawn cable wire.

Main purpose of the present utility model is to provide a kind of cable wire strand to draw device, with a metal spring leaf uphold as the control calvus or after the actuation mechanism that contracts, since this metal spring leaf press by or pushing direction have preferable elasticity tension, so when calvus is in stretched condition, can provide more firm ejection force, so that operation.

According to the utility model, provide a kind of cable wire strand to draw device, comprise stake body, armed lever, ratchet, following lower end hook and cable wire, wherein, and armed lever and the concentric stake body inside that is articulated in of ratchet, the stake body top is provided with hook on; Cable wire one end is fixed in the bottom of stake body, and the other end then is wound on the ratchet; The pulley of lower draw-bar is passed in the cable wire bottom, it is characterized in that:

Calvus is articulated on the armed lever by a fulcrum, calvus rear end captive joint one metal spring leaf, the other end of this metal spring leaf then is fixed on the armed lever, and make its spacing from the length that is slightly less than metal spring leaf, make the metal spring leaf after the connection be case of bending up or down, and can make the calvus front end insert ratchet or break away from ratchet by this flexure operation.

Draw device according to cable wire strand of the present utility model, its feature is that also ratchet can adopt both sides all to have the ratchet of ratchet, and it is corresponding with it then respectively to establish a calvus on the opposite face of ratchet, and this two calvus fastens on fulcrum, the two ends of fulcrum then are articulated on the armed lever, but make two calvus be the interlock slew mode; Wherein hold captive joint one metal spring leaf after the calvus, the other end of this metal spring leaf then is fixed on the armed lever, and makes its spacing from being slightly less than metal spring leaf length.

Relevant the utility model is technological means and the structure that achieves the above object and adopted, and existing conjunction with figs. is described in detail as follows:

Fig. 1 is the constructional drawing that the utility model cable wire strand is drawn device.

Fig. 2 is the enforcement figure of the state that contracts after the utility model calvus is.

Fig. 3 is the enforcement figure that the utility model calvus is stretched condition.

Fig. 4 is the constructional drawing that known cable wire strand is drawn device.

See also accompanying drawing, according to the utility model, armed lever 1, ratchet 2 are articulated in stake body 3 inside with one heart, and stake body 3 tops are provided with a hook 31, draw device integral body to be used for hanging strand.Cable wire 4 one ends are fixed in the bottom of stake body 3, and the other end then is fastened on ratchet 2.The pulley 51 of another hook 5 is passed in cable wire 4 bottoms, makes this hook 5 can do the action of similar pulley according to the length of cable wire 4.

All be provided with ratchet on the both ends of the surface of ratchet 2, it is corresponding with it that each end face respectively is provided with a calvus 6.This two calvus 6 fastens on a fulcrum 61, and the two ends of fulcrum 61 then are articulated on the armed lever 1, but makes two calvus 6 be the state of interlock rotation.Wherein, rear end captive joint one metal spring leaf 7 of a calvus 6, the other end of this metal spring leaf 7 then is fixed on the armed lever 1, and makes its spacing from the length that is slightly less than metal spring leaf 7, makes metal spring leaf 7 after the connection be up or down case of bending.

The utility model promptly utilizes the metal spring leaf 7 of this case of bending to control calvus 6, as shown in Figure 2, when pressing by metal reed 7 it is when being bent downwardly, the rear end that reed 7 can promote calvus 6 with its reclinate elasticity trend make calvus 6 front ends mention slightly and break away from and ratchet 2 engagements.Otherwise, when pulling metal spring leaf 7 and make it be upwards tortuous, as shown in Figure 3, reed 7 can improve the rear end of calvus 6 with the elasticity trend of its K/UP, and then the front end of compacting calvus 6 and with ratchet 2 engagement, make armed lever 1 be able in the stroke rotate strand and draw by means of calvus 6 promotes ratchets 2 last pulling.

What be worth emphasizing is, it is the actuation mechanism of utilizing wound spring to uphold or withdraw as calvus B that known cable wire strand is drawn device, as shown in Figure 4, since this wound spring press by or the metal spring leaf 7 that uses not as the utility model of the thrust of ejection direction, therefore use and go up normal slippage, the unsettled phenomenon of producing; Particularly after using after a while, the result of elastic force deficiency will more make its fluctuation of service.So, the utility model be suitable for press by or the ejection direction metal spring leaf of making elastic stretch replace it, show through long-term test, really can obtain the practical function one easy to operate, that stability is preferable.In addition; Because the utility model utilizes two calvus to cooperate ratchet both sides ratchet to make the sync card stopper and does, known one-sided ratchet be can effectively improve and frequent beat, wild effect moved, draw effect and obtain the preferable strand of stability.
