Abstract
The utility model discloses a stair chain shock absorption mechanism and relates to the technical field of staircases. The stair chain shock absorption mechanism comprises an axle tube, stair chain wheels and duplex chain wheels. The stair chain wheels are arranged at two ends of the length direction of the axle tube, and the duplex chain wheels are arranged on the stair chain wheels. Shock rings are arranged in tooth grooves of the stair chain wheels. The purposes that the stair chain shock absorption mechanism is simple in structure, collision among stair chains and the stair chain wheels is avoided, and the service life of staircase stairs is prolonged are achieved.
Description
Technical field
The utility model relates to the technical field of staircase.
Background technology
Present stair step is to arrange ladder sprocket wheel at the two ends of central siphon, arranges duplex chain wheel on ladder sprocket wheel, and staircase is when normal operation, and step chains is engaged in the ladder sprocket wheel motion.Step chains contacts with collision in ladder sprocket wheel engagement operation process and produces larger noise, and the sleeve of step chains and the teeth groove of ladder sprocket wheel are caused wearing and tearing.Reduced the service life of staircase.
Summary of the invention
The utility model purpose is to provide a kind of simple in structure, avoids the collision of step chains and ladder sprocket wheel, extends the stair step step chains damping in service life.
A kind of step chains damping comprises central siphon, ladder sprocket wheel, duplex chain wheel, and ladder sprocket wheel is arranged at the two ends of central siphon length direction, arranges duplex chain wheel on ladder sprocket wheel, arranges shock ring in the teeth groove of above-mentioned ladder sprocket wheel.
The utility model is arranged minor sprocket on central siphon.
The utility model is installed shock ring in the teeth groove of ladder sprocket wheel after, step chains contacts with the shock ring collision, has effectively reduced noise, has improved simultaneously the service life of step chains and ladder sprocket wheel, has extended simultaneously the service life of stair step.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is elaborated:
As shown in Figure 1, a kind of step chains damping comprises central siphon 1, ladder sprocket wheel 2, duplex chain wheel 3, and ladder sprocket wheel 2 is arranged at the two ends of central siphon 1 length direction, arranges duplex chain wheel 3 on ladder sprocket wheel 2, arranges shock ring 4 in the teeth groove of above-mentioned ladder sprocket wheel 2.
As shown in Figure 1, arrange minor sprocket 5 on central siphon 1 of the present utility model.
Shock ring of the present utility model is to make with the EU material, has preferably the characteristics such as elasticity, wear-resisting, fuel resistance, hydrolysis.Shock ring is arranged in the teeth groove of ladder sprocket wheel, has played the effect of bumper and absorbing shock.
