Embodiment

Below in conjunction with accompanying drawing, optimal technical scheme of the present utility model is described in detail.

As shown in the figure, a kind of high pulling torque power of the present utility model stores and slow take-off equipment, comprise outer hull 1, two ends in described outer hull 1 are respectively arranged with stage clip 2 and extension spring 3, tooth bar 4 it is provided with between stage clip 2 and extension spring 3, stage clip 2 and extension spring 3 are common to tooth bar 4 reactive force, described tooth bar 4 is positioned on the elastic force direction of stage clip 2 and extension spring 3, the middle section of tooth bar 4 has tooth, tooth bar 4 is provided with the gear 5 that the tooth with tooth bar 4 engages, outer hull 1 is provided with rotating shaft 6, rotating shaft 6 runs through outer hull 1 and arranges, outer hull 1 there is hole, rotating shaft 6 is arranged through hole, rotating shaft 6 connects gear 5 and drives it to determine axle rotation, described rotating shaft 6 is also provided with the torsion bar 7 pulled by external force,

One end that described tooth bar 4 connects extension spring 3 arranges Packed extension spring cover 8, extension spring 3 is positioned at extension spring cover 8, it is running fit between the end of tooth bar 4 and extension spring cover 8, it is piston end that described tooth bar 4 connects one end of extension spring 3,8 running fit are overlapped in piston end and extension spring, on extension spring cover 8, one end of tooth bar 4 being provided with fluid check valve 9 and fluid venting valve 10, be filled with fluid in described outer hull 1, the turnover oil flow of described fluid check valve 9 is greater than the turnover oil flow of fluid venting valve 10.

Peripheral equipment is propulsion source, pulling torsion bar 7 to rotate, torsion bar 7 is rotated by rotating shaft 6 driven gear 5, and gear 5 is by making tooth bar 4 move to stage clip 2 direction with engaging of tooth bar 4, tooth bar 4 compression press spring 2 also draws high extension spring 3, and stage clip 2 and extension spring 3 start to store the energy of motor; Along with the movement of tooth bar 4, in extension spring cover 8, space increases, the fluid filled in outer hull 1 enters extension spring cover 8 fast by fluid check valve 9, when the stroke of stage clip 2 and extension spring 3 reaches maximum all soon, both spring power stores energy and reaches maximum, the now dead torsion bar 7 of fixing lock, device inside then realizes the object of storage power, uses at any time altogether.

Otherwise, when needs release uses this storage power, unclamp the dead torsion bar 7 of fixing lock, stage clip 2 and extension spring 3 start to discharge energy, stage clip 2 promotes tooth bar 4, extension spring 3 traction rack 4, two power synchronously carry out, tooth bar 4 moves to opposite direction, extension spring is overlapped 8 inner fluids and is started to be squeezed, owing to fluid has incompressibility, fluid will overcome the elastic force of stage clip, fluid venting valve 10 starts to open, owing to the exhaust channel of fluid venting valve 10 is significantly smaller than fluid check valve 9, cause extension spring to overlap 8 inner fluids can not discharge very soon, the diameter of the aperture of fluid venting valve 10 is through calculating, fluid can only be flowed out with certain flow, so that tooth bar 4 can only move with certain speed, torsion bar 7 is avoided to brandish fast, achieve the slow output of power and the movable at the uniform velocity at a slow speed of device feature.

Further, described gear 5 place arranges one group of bearing stop means, bearing stop means comprises bearing spider 11, bearing spider 11 is provided with bearing end cap 12, between described bearing spider 11 and bearing end cap 12, there is flange bearing 13, described gear 5 is between one group of bearing stop means, and described rotating shaft 6 is positioned at flange bearing 13.

Further, described fluid venting valve 10 overlaps the level height of the level height on 8 higher than fluid check valve 9 in extension spring.

Further, described stage clip 2 periphery arranges compression spring sleeve 14.

Taking the above-mentioned desirable embodiment according to the application as enlightenment, by above-mentioned description, relevant staff in the scope not deviateing this application technological thought, can carry out various change and amendment completely. The content that the technical scope of this application is not limited on specification sheets, it is necessary to determine its technical scope according to right.
