Abstract
The utility model relates to a cord pulling rotary structure, composed of a cross rod whose middle part is provided with a through hole, a rotary shaft which passes through the through hole vertically, a soft cord whose both ends are symmetrically fixedly connected to the cross rod, an upright plate which is vertically fixedly connected to the cross rod and a spring which is arranged considering the rotary shaft as a shaft, the outer end of the mainspring spring is connected to the upright plate, and the middle part of the soft cord is fixedly connected to the rotary shaft. The utility model avoids the winding dead center of the soft rope of a traditional cord pulling rotary structure and can ensure the compound of the soft rope without special operational requirements. The utility model is suitable for various cord pulling rotation structures.
Description
The utility model relates to a kind of device that rotatablely moves that straight line motion is converted to.What be particularly related to is a kind of cord pulling type rotating mechanism that is wrapped in that axle is gone up and rotates by the moving rotating shaft of the gentle rope band of pulling with flexible strand.
The cord pulling type hand drilling tool that existing a kind of carpenter uses is provided with the cross bar of a through hole and vertically is through the montant in this through hole and a two is affixed with the two ends of cross bar respectively, the top of centre and montant joins flexible strand is constituted by central authorities.Two bars are relatively rotated forward to be wrapped in flexible strand on the montant, pressing down cross bar again impels rope to collapse direct join to drive montant thus and rotate, remove to twine from montant fully at rope and to be the moment of collapsing straight shape and to remove downforce cross bar, the inertia that utilizes montant to rotate oppositely is wrapped in flexible strand on the montant, presses down cross bar again rope pulling montant is rotated.Though this to twine the structure of flexible strand by the montant rotator inertia fully simple, be difficult for grasping, must collapse the winding once more that downforce that straight moment in time removes cross bar could guarantee flexible strand at rope, very easily cause to collapse and directly stop extremely to influence working efficiency.
The purpose of this utility model provides a kind of can the assurance makes flexible strand be wrapped in the cord pulling type rotating mechanism that rotates on the montant.
The cord pulling type rotating mechanism of realizing the purpose of this utility model comprises that its middle part has the cross bar of a through hole, vertically passes a rotating shaft and the flexible strand that this through hole is provided with, the two ends symmetry of flexible strand is fixed on the cross bar, the middle part is fixed in the rotating shaft, solid rope point external position place at cross bar vertically is provided with a riser, the solid rope point top position of montant is sentenced rotating shaft and is provided with a clockwork spring for axle, and the outer end of clockwork spring is connected on the riser on the cross bar.Clockwork spring can take with its outer end be fixed on the riser, mode inner and that rotating shaft is slidingly connected is provided with, also it inner can be fixedlyed connected with rotating shaft, outer end and riser be the mode that is slidingly connected and be provided with, also can adopt its inside and outside two ends all are the mode that is slidingly connected with rotating shaft and riser respectively are provided with.When clockwork spring is full releasing state, flexible strand is the state that is wrapped in the rotating shaft, pressing down cross bar then makes rope pulling rotating shaft rotate, also make simultaneously the tight energy storage of clockwork spring dish, in the downforce on removing cross bar, clockwork spring also rotates and heavily flexible strand is wrapped in the rotating shaft with regard to drive rotating shaft thereupon releasing energy.Thereby keep the reciprocal rotation of rotating shaft.
The operation that resets of the flexible strand that the utility model utilizes clockwork spring to realize restricting to draw rotating mechanism has been avoided the winding dead point that exists in the prior art, need not special operation and requires just can realize its flexible strand after-combustion reliably.Can be used for various cord pulling type rotating mechanisms.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further details.
Fig. 1 is embodiment 1 a structural representation
Fig. 2 is the A-A plan view of Fig. 1
Fig. 3 is embodiment 2 a structural representation
Embodiment 1:
As shown in Figure 1, 2, the utility model is made of cross bar 1, rotating shaft 2, flexible strand 3, riser 4 and clockwork spring 5 in the present embodiment, interposition at cross bar 1 is equipped with a through hole 6, this through hole setting is passed in rotating shaft 2, two ends B, the C of flexible strand 3 symmetry respectively is fixed on the cross bar 1, and its middle part D then is fixed in the rotating shaft 2; Riser 4 vertically is installed in the outer end position place of the solid rope point of cross bar 1, and clockwork spring 5 is arranged on the top position place of the solid rope point of rotating shaft 2, and it is inner affixed with rotating shaft 2, and the outer end then is inserted into and is sliding type with riser 4 in the chute 7 that is provided with on the riser 4 and is connected.Also chute can be set in rotating shaft, the inner of clockwork spring is plugged on to make it in the chute to be with rotating shaft is slidingly connected.Perhaps inside and outside two ends all are plugged on respectively to be in the corresponding chute and are slidingly connected.Pressing down cross bar moves downward it and when driving flexible strand pulling rotating shaft, chute on the riser 4 then makes the outer end of clockwork spring be retained in the original place and does not change its position with the uplink and downlink of riser, thereby guarantees the normal energy storage and the rope woolding that releases energy of clockwork spring.
For overcoming the incidental modification of clockwork spring longitudinal direction, can be at the upper and lower postive stop baffle 8,9 that is provided with separately of clockwork spring, this baffle plate can become disc with the clockwork spring respective design, the outer end of clockwork spring is fixed on the postive stop baffle, in the outer end of baffle plate a slide block 6 that matches with riser chute 7 is set, utilizes the slip of this slide block in chute 7 to guarantee relative displacement between clockwork spring and riser.
Embodiment 2:
As shown in Figure 3, the cross bar of present embodiment and riser are served as in the lump by a circular cylinder 9, and clockwork spring, flexible strand are provided with by the mode of all continuing to use embodiment 1.
Claims (4)
1, a kind of rope formula rotating mechanism, comprise that its middle part has the cross bar of a through hole, vertically passes a rotating shaft and the flexible strand that this through hole is provided with, the two ends symmetry of flexible strand is fixed on the cross bar, the middle part is fixed in the rotating shaft, it is characterized in that also vertically being provided with a riser at the solid rope point external position place of described cross bar, the solid rope point top position of rotating shaft is sentenced outer end that rotating shaft is provided with a clockwork spring for axle and is connected on the riser on the cross bar.
2, cord pulling type rotating mechanism as claimed in claim 1 is characterized in that described riser is provided with a vertical chute, and the outer end of clockwork spring is installed in this vertical chute and can upper and lower slip in this chute.
