Embodiment

Shown in Fig. 1,5, a kind of damping fixing device, comprise and be used for fixture 50 is assemblied in positioning and fixing mechanism on the fixed body 60, described positioning and fixing mechanism comprises shock structure 1 that is connected with fixed body 60 and the shock absorbing sleeve 2 that is connected with fixture 50, shock absorbing sleeve 2 is arranged on the outer wall of fixture 50, is the part of fixture 50.Described shock absorbing sleeve 2 is sleeved on outside the shock structure 1, is set with elastic buffering pad 3 between described shock structure 1 and shock absorbing sleeve 2, and described cushion pad 3 separates shock structure 1 and do not contact with shock absorbing sleeve 2.

Shown in Fig. 2,5, described shock structure 1 is cylindric, and its front end is provided with the joint 13 that removably connects with fixed body 50, the joint 13 outer outside threads that are provided with, the screw that is provided with on the joint 13 of shock structure front end and the fixed body 60 is spirally connected, and fixture 50 is fixed on the fixed body 60.The rear end of shock structure 1 is provided with the block 11 that prevents that shock absorbing sleeve 2 and cushion pad 3 from coming off.Block 11 external diameters are greater than the external diameter of shock structure 1, and are not less than the internal diameter of shock absorbing sleeve 2, and block 11 is just held shock absorbing sleeve 2 and cushion pad 3 like this, prevents that the two from coming off.

As shown in Figure 2, owing to be provided with step 12 on the shock structure behind the joint 13 1, when shock structure 1 was spirally connected fixed body 60, described step 12 roof pressures were on fixed body 60 outer walls.Spacing between step 12 and block 11 is constant like this, the decrement of can controlling Design good cushion pad 3, and the cushion pad 3 of avoiding excess compression to cause is crushed to death, or does not push down cushion pad 3 and make cushion pad 3 not play the effect of bumper and absorbing shock.

As shown in Figure 1, shock absorbing sleeve 2 is a tubular, is fixed on the outer wall of fixture 50.The shock absorbing sleeve 2 of present embodiment is cylindric.

As shown in Figure 3, the tubular that cushion pad 3 is made for elastic material, its outer wall shape is identical with shock absorbing sleeve 2 inner wall shape, inner wall shape is identical with shock structure 1 outer wall shape, and because cushion pad 3 is in order to absorb vibration, therefore cushion pad 3 cooperates with shock absorbing sleeve 2 and shock structure 1 no gap respectively, the external world is delivered to the vibration on the shock structure 1, major part is cushioned the resiliently deformable absorption that pad 3 is taken place, and can not pass to the vibration that shock absorbing sleeve 2 causes fixture 50, thereby avoided the damage of fixture 50.The cushion pad 3 of present embodiment is to be cooperate with shock structure 1 and shock absorbing sleeve 2 cylindric.

Described cushion pad 3 at least one end are provided with outer flanging 31, and outer flanging 31 is used to separate the end and the shock structure 1 of shock absorbing sleeve 2.Cushion pad 3 one ends of present embodiment are provided with an outer flanging 31, and in actual use, shock structure 1 is outer can cushion pad 3 of suit, and the outer flanging 31 of cushion pad 3 is arranged between block 11 and shock absorbing sleeve 2 lower ends.As shown in Figure 5, shock structure 1 is outer can two cushion pads 3 of suit, the outer flanging 31 of two cushion pads 3 lays respectively at the upper and lower end face of shock absorbing sleeve 2, and such structure makes cushion pad 3 that shock absorbing sleeve 2 and shock structure are separated fully, has guaranteed axially all fine with damping effect radially.

As shown in Figure 3, to be provided with the cross section of at least one the first dashpot 32, the first dashpots 32 be arc, V-arrangement, shape such as square to the internal face of cushion pad 3.First dashpot 32 has increased the elastic deformation amount of cushion pad 3, has also just increased the ability of the absorption vibration of cushion pad 3, and buffering and damping effect is better.Each first dashpot 32 is along cushion pad 3 internal face circumference one circle to be set, and present embodiment is provided with two first dashpots 32.First dashpot 32 also can be set on the outer wall of cushion pad 3, and its effect is consistent with first dashpot, 32 effects of cushion pad internal face.It is circular groove that the outer flanging 31 of cushion pad is provided with at least one the second dashpot 30, the second dashpots 30.The main purpose of first dashpot 32 is to increase buffering and damping effect, and cushion pad 3 of the present utility model also can not be provided with dashpot 32, has better flexible material and makes cushion pad 3 and will play good bumper and absorbing shock effect as long as adopt.

As shown in Figure 4, be the another kind of mode of execution of cushion pad 3, flanging 31 outside the two ends of cushion pad 3 all are provided with, the length of cushion pad 3 and shock absorbing sleeve 2 length cooperate, and make two outer flangings 31 of cushion pad 3 be fitted on two end faces of shock absorbing sleeve 2.Such cushion pad 3 just can be isolated shock structure 1 and shock absorbing sleeve 2 fully.

As shown in Figure 5, the damping fixing device is used for fixture 50 fixing, therefore, both sides at fixture 50 are provided with the damping fixing device respectively, the shock absorbing sleeve 2 of damping fixing device is fixed on fixture 50 outer walls, and shock structure 1 is screwed onto on the fixed body 60, and it is fixing to be about to fixture 50.Being connected of shock structure 1 and fixed body 60 can also be other modes, for example: multiple modes such as riveted joint, draw-in groove clamping, pin connection.

During installation, earlier cushion pad 3 is sleeved on the shock structure 1, again the two is installed in the shock absorbing sleeve 2, then the joint of shock structure 1 front end is screwed onto in the screw on the fixed body 60, be about to fixture 50 and fix.
