Description
Technical field
This utility model is related to chain technical field and in particular to a kind of chain tightener.
Background technology
During using chain, chain gear transmission mode, often the phenomenons such as loose chain, chain rupture in use in chain, tight
It is required to 2-3 people's cooperation when chain or contracting chain just can complete, when especially manpower pulls thicker chain, time-consuming, laborious, and
Worker's high labor intensive.
Utility model content
This utility model provides a kind of chain tightener, and it reduces worker's labor intensity, improves tight chain or contracting speed chain, carries
High workload efficiency.
For solving the problems, such as prior art, the technical solution of the utility model is：
For solving the problems, such as prior art, the technical solution of the utility model is：A kind of chain tightener, including connector
First, connector two, screw rod one, screw rod two and of bonding bidirectional adjuster, described connector one, the structure of connector two are
" U " shape steel plate, lower steel plate on the opening of " U " shape steel plate is respectively arranged with two holes, described of bonding bidirectional adjuster
Structure include rectangular channel, the both sides of rectangular channel are protruded, and are provided centrally with through hole, are provided with female thread in through hole, described
One end welding of screw rod one be arranged in " U " type groove of connector one, in of the other end and of bonding bidirectional adjuster
Screw thread is connected, and one end welding of described screw rod two is arranged in " U " type groove of connector two, the other end and the two-way tune of of bonding
Another female thread of regulating device is connected.
Described screw rod one and model M22 of screw rod two, length is 275mm.
The steel plate thickness of described connector one and connector two is 10mm, length × a width of 100 × 75mm.
Compared with prior art, advantage of the present utility model is as follows：When under this utility model chain sprocket kind of drive, fall
The low labor intensity of artificial chain or contracting chain, decreases chain or tight chain personnel, and this device have once plus
Work, long term benefit, cost-effective, reduce chain or contracting chain personnel labor intensity, improve labor efficiency.
Brief description

Fig. 3 is the B B sectional view of Fig. 1；
Description of reference numerals：1 connector one, 2 connectors two, 3 screw rods one, 4 screw rods two, 5 of bondings are two-way
Adjusting means, 6 holes.
Specific embodiment
Below in conjunction with the accompanying drawings the design is described in detail：
Referring to Fig. 1-Fig. 3：A kind of chain tightener, including connector 1, connector 22, screw rod 1, screw rod 24 and of bonding
Bidirectional adjuster 5, described connector 1, the structure of connector 22 are " U " shape steel plate, on the opening of " U " shape steel plate
Two holes 6 are respectively arranged with lower steel plate, two Kong Jun are slightly larger than chain shaft, aperture to be defined through chain rivet, between holes
Distance is the distance between adjacent chain rivet of chain, " U " shape steel plate upper and lower ear distance all slightly larger than the width of chain, described company
The steel plate thickness of fitting 1 and connector 22 is 10mm, length × a width of 100 × 75mm, described of bonding bidirectional adjuster 5
Structure include rectangular channel, the both sides of rectangular channel are protruded, and are provided centrally with through hole, are provided with female thread in through hole, described
One end welding of screw rod 1 be arranged in " U " type groove of connector 1, one of the other end and of bonding bidirectional adjuster 5
Female thread is connected, and one end welding of described screw rod 24 is arranged in " U " type groove of connector 22, and the other end is double with of bonding
It is connected to another female thread of adjusting means 5.
Described screw rod 1 and model M22 of screw rod 24, length is 275mm.
Using method of the present utility model：When carrying out tight chain or contracting chain, selected suitably tight according to chain width
Chain device is it is ensured that chain can pass through the rectangular degree of lip-rounding connection ring at chain tightener two ends.According to required chain length, clip in needs
Chain position, is connected with the axis hole of the two neighboring chain rivet of chain and the connection of the rectangular degree of lip-rounding connection ring at chain tightener two ends
Hole, after bolt fastening firmly, is linked closely with the U-shaped of bonding bidirectional adjuster that handss rotate chain tightener, until chain is elastic
After degree meets the requirements, connect chain, carry out chain link or contracting chain.
Tight chain or contracting chain finish, and are released with the U-shaped of bonding bidirectional adjuster that handss rotate chain tightener, and dismounting is tight
The connecting bolt of chain device rectangular degree of lip-rounding connection ring, checks chain sprocket drive mechanism, the tightness of chain, until being suitable for
Only.
The tight chain of this utility model chain tightener is simple, and entirely tight chain process only needs a people can complete, and reduces manually tight chain
When worker labor intensity, decrease tight chain or contracting chain personnel, improve tight chain efficiency it is achieved that mechanization substitute.
