Specific embodiment

In order to facilitate the understanding of those skilled in the art, below in conjunction with attached drawing and embodiment to the utility model carry out into One step detailed description.

As shown in attached drawing 1~5, the damping turnover device that the present embodiment discloses includes shell 1 open at one end and is installed on The end cap 2 of 1 open outer end of shell, interior elastic component, damping movement block 4, bearing 5 and rotary shaft 6, the elastic component of being equipped with of shell 1 include The interior pressure spring 7 for being set in 6 inner end of rotary shaft and the external pressure spring 8 for being set in interior 7 periphery of pressure spring, the length of interior pressure spring 7 and external pressure spring 8 Identical, bearing 5 is set in rotary shaft 6, which is connect by rotary shaft 6 with flip piece, and flip piece can be The devices such as automobile tail gate, washing machine flip lid, refrigerator flip lid or closestool plate flip lid.

In the present embodiment, 1 other end of shell is equipped with regulating mechanism 3, which includes being set to shell 1

The adjusting for being inside butted on the gasket 31 of elastic component end face, being installed on the nut 32 of 1 side of shell and cooperating with nut 32 Screw 33,33 inner end of adjusting screw and gasket 31 connect；It is equipped with short slot 11 in 1 outer end of shell, tune is installed in short slot 11 Nodal plate 34, nut 32 are hexagonal socket nut, and nut 32 matches connection with adjustment sheet 34.When forward direction adjusts adjusting screw 33, spiral shell Female 32 generate gasket 31 is axially displaced inward, so that 31 compression elastic piece of gasket, achievees the purpose that adjust spring force size, from And ensure that the damping of turnover device, use is safer, prevents safety accident.

In addition, rotary shaft 6 includes stinging positioned at the interior axle portion 61 of inner end, positioned at middle part with what damping movement block 4 was connected Zoarium 62 and the outer axle portion 63 for stretching out 2 outer end of end cap are equipped with circumferential groove 621 in the outer end of occlusion body 62, set in groove 621 There is a mounting hole 622, a pin shaft 9, the 9 spherical shape in top of pin shaft are installed in mounting hole 622；It is fitted in groove 621 Two stabilizer blades of one U-shaped catapult 10, catapult 10 are installed on shell 1, and 9 top of pin shaft is slightly above outer axle portion 623, so that pin shaft 9 Catapult 10 can be squeezed when being rotated with rotary shaft 6.

When the damping turnover device original state, the occlusion body 62 of rotary shaft 6 is engaged with damping movement block 4 closely to be connected It connecing, interior pressure spring 7 and external pressure spring 8 are in compressive state, and flip piece is in closing lid state, meanwhile, pin shaft 9 is with 6 direction of rotary shaft In the U-type groove of catapult 10；When opening flip piece manually, rotary shaft 6 is rotated in the forward direction, and is engaged body 62 far from damping engaged therewith It is moved outside movable block 4, i.e. rotary shaft 6, the elastic force release of interior pressure spring 7 and external pressure spring 8, meanwhile, pin shaft 9 is rotated with rotary shaft 6, until After uncapping, opening of the pin shaft 9 towards catapult 10.The release of the elastic force of interior pressure spring 7 and external pressure spring 8, and occlusion body 62 and damping The separation of movable block 4 provides power-assisted to uncap, and has the function of angle mechanical position limitation of uncapping, and is engaged body 62 and damping movement The occlusion design of block 4 substantially reduces frictional resistance, process of uncapping Portable power saving.

When needing flip piece on manual cover, it is manually pressed by flip piece, rotary shaft 6 reversely rotates, and occlusion body 62 is moved towards damping Motion block 4 is mobile, i.e., moves in rotary shaft 6, and interior pressure spring 7 and external pressure spring 8 are squeezed, and elastic force is gradually increased, meanwhile, pin shaft 9 is with rotation Axis 6 rotates, and pin shaft 9 gradually rotates, and touches and squeeze catapult 10, and catapult 10 deforms, until occlusion body 161 and damping movement block 14 The close connection of occlusion, in closing lid process, not only interior pressure spring 7 and external pressure spring 8 provide resistance, moreover, pin shaft 9 is squeezed since touching Pressure catapult 10 to closing lid completion also provides resistance, and pin shaft 9 and 10 compressional movement of catapult cooperate, and has reached the effect of buffer deceleration Fruit, preferably eliminates the shock problem generated when gravity is converted during closing lid, and whole more stable slow closure eliminates folder Hurt the risk of hand.Due to the 9 spherical shape in top of pin shaft, the compressional movement of pin shaft 9 and catapult 10 will not scratch catapult 10, will not Generate the impurity such as iron filings.

In the present embodiment, the occlusion starting point 623 of occlusion body 62 is fillet, so that rotary shaft 6 drives occlusion body 62 and resistance When Buddhist nun's movable block 4 is engaged work, occlusion starting point 623 will not scratch damping movement block 4, will not generate the impurity such as iron filings, prevent Impurity effect occlusion transmission, avoids and causes Caton situation, guarantees that occlusion work is more stable and more reliable.

The utility model damping turnover device is reasonable in design, can be in real time according to practical feelings by the way that regulating mechanism is arranged Condition adjusts elastic component compressed value, guarantees the damping of turnover device, use is safer, prevents safety accident；Flip piece Stroke control is also more stable and reliable, by setting pin shaft 9 and catapult 10, in the damping of pressure spring, pin shaft 9 and 10 friction and Extrusion of catapult Collective effect under, not only realize easily open flip piece purpose, realize uncap 30 ° or more when, can arbitrarily stop； And when low-angle is closed and covered, such as 30 ° hereinafter, provide resistance in time, remains to steady slowly closure, and at 15 °, overturning Part meeting automatic slowly decline, realizes the purpose of safer closure flip piece, eliminates the risk of hand clamping, overcome on the market The problem of failure is damped when 30 ° of turnover mechanism low-angle or less closing lids, use is safer, longer life expectancy.

Above-described embodiment is preferred embodiment of the utility model, and non-limiting exhaustion, this reality under same idea There can also be other variations with novel, such as elastic component is torsional spring, which can equally reach the utility model design and want It asks.It should be noted that any obvious replacement is in this reality under the premise of not departing from the present utility model design Within the scope of novel protected.
