ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a shock absorbing assembly. More particularly, the present invention relates to a shock absorbing assembly for a transmission mechanism.
Referring to
FIGS. 1
to
3
A, a shock absorbing device
20
has a first collar
21
, a first sleeve
22
inserted in the first collar
21
, the first collar
21
having a lug
24
, the first sleeve
22
having an elastic cylinder
23
, a washer
27
, a first screw rod
15
, and a second screw rod
17
. The lug
24
has a round hole
25
. The elastic cylinder
23
has a center hole
26
. A transmission mechanism
30
has an outer casing
31
. A hollow tube
32
is connected to a bottom of the outer casing
31
. A rod
11
is disposed on a main frame
10
. Two upper bars
12
are disposed on the rod
11
. A hollow pillar
14
is disposed between the upper bars
12
. The hollow pillar
14
has a through aperture
13
. The first screw rod
15
passes through the washer
27
, the center hole
26
of the elastic cylinder
23
, the through aperture
13
of the hollow pillar
14
, a second sleeve
22
′, a second collar
21
′, and a first nut
16
. The second screw rod
17
passes through the round hole
25
of the lug
24
, the hollow tube
32
, and a second nut
18
. Since the first collar
21
contacts the upper bar
12
, a noise will occur while the first collar
21
bumps the upper bar
12
. Furthermore, the shock absorbing area of the shock absorbing device
20
is small so that the shock absorbing effect is not very effective.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a shock absorbing assembly which has an effective shock absorbing effect.
Accordingly, a transmission mechanism has an outer casing. A hollow tube is connected to a bottom of the outer casing. A main frame has a panel having a round aperture. A shock absorbing assembly comprises a buffer device, a positioning seat disposed on the buffer device, and a screw rod fastening the positioning seat and the hollow tube together. The buffer device has a shock-absorbing elastic block, an upper metal plate disposed on a top portion of the shock-absorbing elastic block, a lower metal plate disposed on a bottom of the shock-absorbing elastic block, an upper stud disposed on a top portion of the upper metal plate, and a lower stud disposed on a bottom of the lower metal plate. The positioning seat has a bottom through hole, and two upper bars enclosing two ends of the hollow tube. Each of the upper bars has a through aperture. The upper stud passes through the bottom through hole of the positioning seat. A first nut fastens the positioning seat and the upper stud together. The lower stud passes through the round aperture of the panel. A second nut fastens the panel and the lower stud together.
