Abstract

A regulator which can automatically adjust the length of a chain, adds a vertical stick, a lever, an extension spring and a rotary wheel onto the vehicle underframe to make the rotary wheel haul the chain tightly all along under the pulling force of the extension spring, thus to achieve the purpose of automatically adjusting the length of the chain.

Description

Chain automatic regulator

1, technical field:

The utility model relates to a kind of chain automatic regulator, especially can regulate chain length automatically under travelling state, makes under steam, can not fall down chain.

2, background technique:

At present, known ZIPPER ASSEMBLER:, all be to use chain as two-wheeled motorcycle, bicycle, motor tricycle, storage battery car, tricycle or the like, chain has been grown service time, will be elongated automatically, when wanting to regulate chain length, must stop, open rear axle, time-consuming, hard, take a lot of work, often under travelling state, chain will fall down or grilled teeth because of long, it is dangerous to bring for the person of riding, and falls, breaks sometimes chain sometimes, sometimes with present situations such as chain block.

3, summary of the invention:

The purpose of this utility model provides a kind of chain automatic regulator, it can not only regulate chain length automatically under the state of sailing of going slowly, and can not grow and fall down running at high speed down or on rough road, exercising and can regulate chain length automatically yet because of chain.

The utility model adopts following technical proposal:

On the ZIPPER ASSEMBLER underframe, by adorning a montant, one of a montant other end and an active lever links, an extension spring and a transmitting gear are equipped with in the active lever other end, the extension spring the other end also is installed on the ZIPPER ASSEMBLER underframe, active lever surely closes the bottom surface of a transmitting gear and a following chain mutually and rotates all the time and chain is strained automatically, so reach the purpose of automatic adjusting chain length under tension spring tension.

The beneficial effects of the utility model are:

Under vehicle travelling state, chain is fallen down or grilled teeth, utilize lever principle, only on body frame, increase several widgets, simple in structure.

4, description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified:

Scheme, be structural representation of the present utility model.

1. chains among the figure, 2. master gear, 3. ZIPPER ASSEMBLER underframe, 4. montant, 5. fixing Luo silk, 6. rotating shaft, 7. fixed hook, 8. extension spring, 9. fixing extension spring Luo silk, 10. turning gear wheel shaft, 11. transmitting gears, 12. active levers, 13. driven gears.

5, embodiment:

In the drawings, one of chain (1), master gear (2) and montant (4) all is contained on the ZIPPER ASSEMBLER underframe (3), montant (4) other end links by rotating shaft (6) and (12) one of active levers, and fixedly extension spring screw (9) and turning gear wheel shaft (10) and transmitting gear (11) are equipped with in active lever (12) other end; (8) one of extension springs link with fixed hook (7), the other end and fixedly extension spring screw (9) link, fixed hook (7) and driven gear (13) also are contained on the ZIPPER ASSEMBLER underframe (3).

Claims

1, a kind of chain automatic regulator, it is characterized in that: on the ZIPPER ASSEMBLER underframe, by adorning a montant, one of a montant other end and an active lever links, an extension spring and a transmitting gear are equipped with in the active lever other end, and the extension spring the other end also is installed on the ZIPPER ASSEMBLER underframe, and active lever is under tension spring tension, all the time a transmitting gear and a following chain bottom surface are surely closed mutually and rotated and chain is strained automatically, so reach the purpose of automatic adjusting chain length.

2, require 1 described chain automatic regulator according to power, it is characterized in that: transmitting gear is installed in the bottom surface of a following chain and surely closes and rotate with chain.
