The specific embodiment
Fig. 3 is for a kind of damper of the utility model and use the decomposing schematic representation of the affairs machine of this damper, and the local enlarged diagram of Fig. 4 after be the affairs machine of Fig. 3 assemble.Affairs machine 100 comprises a pedestal 110, a side cover 120, a damper 130 and a loam cake 140.Loam cake 140 is arranged at the top of pedestal 110; Side cover 120 is arranged on the sidewall 112 of pedestal 110; And damper 130 is arranged in the pedestal 110, and is connected between side cover 120 and the pedestal 110, so that side cover 120 can pedestal 110 unlatchings relatively by damper 130.Damper 130 comprises a positioning seat 132, a shell fragment 134, a power transmission shaft 136 and a cam 138.Positioning seat 132 is fixed in pedestal 110, and shell fragment 134 has one first terminal 134a and one second terminal 134b, and the first terminal 134a is fixed in positioning seat 132.Power transmission shaft 136 is arranged between side cover 120 and the pedestal 110, thus side cover 120 be with power transmission shaft 136 be axis of rotation and relatively pedestal 110 open.Be sheathed on power transmission shaft 136 and the cam 138 between side cover 120 and pedestal 110 has a cambered surface 138a, and the second terminal 134b and the cambered surface 138a of shell fragment 134 interfere with each other.Because the second terminal 134b of shell fragment 134 and the cambered surface 138a of cam 138 interfere with each other, in the time of can letting side cover 120 relative pedestal 110 rotations and unlatching, side cover 120 is to fall slowly.
In detail; The power transmission shaft 136 of present embodiment has an external surface 136a and is arranged at a plurality of first dentalation 136b on the external surface 136a; And cam 138 has an inner surface 138b and a plurality of second dentalation 138c on the inner surface 138b are set, and the first dentalation 136b and the second dentalation 138c intermesh.So, can let cam 138 and power transmission shaft 136 that the good binding relation is arranged; Anticipate promptly, the rotational angle of the rotational angle of cam 138 and power transmission shaft 136 is synchronous.
In another embodiment, power transmission shaft 136 ' cross section be shaped as the D font, and cam 138 ' have the perforation of a D font, and perforation along cam 138 ' axially run through cam 138 '.Make power transmission shaft 136 ' cross section shape and cam 138 ' the shape of perforation identical; Also can reach let power transmission shaft 136 ' with cam 138 ' have marriage relation closely; Make cam 138 ' rotational angle and power transmission shaft 136 ' rotational angle synchronous, show like Fig. 5.
In addition, damper 130 can also comprise a plurality of locking parts 139, and the locking part 139 of present embodiment is a screw, and locking part 139 is in order to pass positioning seat 132 and to lock in the pedestal 110, with the relative position of stationary positioned seat 132 with pedestal 110.
The sketch map that Fig. 6 opens for the relative pedestal of side cover of the affairs machine of Fig. 4.Please be simultaneously with reference to figure 3, Fig. 4 and Fig. 6; When side cover 120 relative pedestals 110 rotate with unlatching; Since a side of side cover 120 (indicating) with the power transmission shaft 136 of damper 130 being connected, so side cover 120 is relative pedestal 110 unlatchings of axis of rotation away from the opposite side of pedestal 110 with power transmission shaft 136 relatively with pedestal 110.Specifically, in response to the shape of cam 138, when the gravity of side cover 120 drives power transmission shaft 136 when counterclockwise rotating, cam 138 receives the rotation of power transmission shaft 136 and the second terminal 134b relative to shell fragment 134 rotates.At this moment, with the second terminal 134b of the contacted shell fragment 134 of the cambered surface 138a of cam 138 profile distortion, let the second terminal 134b can contact the cambered surface 138a of cam 138 constantly along cam 138.When the second terminal 134b rotated, the frictional force between the cambered surface 138a of the second terminal 134b and cam 138 can be slowed down the gravity that receives side cover 120 and the velocity of rotation of the power transmission shaft 136 that drives at cam 138.
Fig. 7 is the sketch map of the another kind of embodiment of second end.Please refer to Fig. 7, in this embodiment, the second terminal 134b " alteration of form and be the C font, and cam 138 " is arranged in the second terminal 134b "." cambered surface 138a " and the second terminal 134b because cam 138 " between contact area increase; so the cam 138 " cambered surface 138a " and the second terminal 134b " between frictional force also and then increase, in other words the damped coefficient of damper 130 (being shown in Fig. 3) is also followed increase.So; Change the cam 138 " cambered surface 138a " and the second terminal 134b " between contact area; can change the damped coefficient of damper 130 (being shown in Fig. 3), and then adjust the speed that side cover 120 (being shown in Fig. 4) rotarily opens with respect to pedestal 110 (being shown in Fig. 4).
As stated; The utility model provides a kind of structure the damper different with the structure of existing damper; Though and structure is different, and the damper that the utility model provided is applied in the affairs machine, still can reach the slow purpose of falling of the relative pedestal of the side cover that makes the affairs machine.Again; Be applied to the damper in the affairs machine than having now; The composed component of the damper that the utility model provided have moulding simple relatively, advantage such as be easy to make and obtain, so can reduce the spare part cost of the affairs machine that uses this damper effectively.
Though the utility model discloses as above with embodiment, so it is not in order to limiting the utility model, any under the those of ordinary skill of technical field, when can doing a little change and retouching, and break away from the spirit and the scope of the utility model.
