The utility model has the advantages that: owing to be provided with bumper and damping cushion block, the vibrations of video Play System telltale in vehicle (train, automobile) the operation way have been alleviated effectively, improved video play quality and visual effect, the damage that also can slow down telltale simultaneously increases the service life.
Description of drawings
Fig. 1 is structure and a kind of erection plan of this shock absorption device.
Fig. 2 is the another kind of erection plan of this shock absorption device.
Fig. 3 is another erection plan of this shock absorption device.
The specific embodiment
Referring to Fig. 1: this shock absorption device comprises casing 10 and the bumper that is used to place telltale, and this bumper comprises the pull bar 4 of seat 7, the one band shape boss 8 of a blind pipe shape, and pull bar 4 places in the blind hole of seat 7, its boss 8 and blind hole bearing fit; The pull bar section at boss 8 two ends is with cylindrical compression spring 6,9 respectively; The open end of seat 7 is provided with outside thread, and pipe nut 5 is spirally connected with it, and spring 6,9 is encapsulated in the blind hole, and the two ends of spring 6 are adjacent to the upper limb and the pipe nut 5 of boss 8 respectively, and the two ends of spring 9 are adjacent to respectively at the bottom of the lower edge and blind hole of boss 8.Captive joint with casing 10, passenger car 1 respectively in the two ends of bumper, the drag link end of bumper adopts flange 2, screw 3 to be connected with compartment 1, seat end and casing 10 welding certainly, also can adopt flange, screw to connect (as Fig. 2, shown in Figure 3) as drag link end.In the gap between casing 10 and telltale 12, be provided with the soft elastic material damping cushion block 11 made of rubber, foamed plastic for example.
During mounting shock absorber, there is not the direction restriction, also can be as shown in Figure 2, drag link end connect box 10, the seat end connects compartment 1.
Usually, need only be equipped with a bumper as shown in Figure 2 and get final product effective damping, in order further to strengthen damping effect, preferably be equipped with two bumpers as Fig. 1, even be equipped with four bumpers, be distributed in four bights of casing 10, damping effect can be better.
Referring to Fig. 3: under the situation of erecting stage condition permission, also can bumper all be set at the upper and lower of casing 10, last bumper connects the compartment top board, following bumper connection cabin floor.Compare with the suspension type installation of Fig. 1, Fig. 2, damping effect is better.
