Abstract
The invention relates to a tensioning device capable of rapidly adjusting the tightness of a chain. The tensioning device comprises a supporting rack, wherein the left and right ends of the supporting rack are meshed with a left-handed screw and a right-handed screw which are opposite in screwing direction; the outer ends of the left-handed screw and the right-handed screw are respectively provided with one connecting device. The tensioning device is reasonable in design, simple in structure, convenient in use and high in stability, and can be used for rapidly adjusting the tightness of the chain or other connecting pieces, improving the working efficiency and alleviating the labor intensity of workers.
Description
Technical field
The present invention relates to the device that tightly rises in the regulating device field, especially a kind of chain elasticity rapid adjustment device that tightly rises.
Background technique
All can use chain pull-up article at present in a lot of occasions, as usually used chain pull-up hatchcover or other equipment on hull, after the long-time use of chain, can fluff, therefore in use often need to be according to actual conditions, adjust its elasticity by changing the chain mounting point, it is longer that this adjusts the mode time, not only can cause working efficiency to descend, but also increased staff's labor intensity.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of time saving and energy saving device that tightly rises that can rapid adjustment chain elasticity that uses is provided.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of chain elasticity rapid adjustment device that tightly rises, it is characterized in that: comprise a supporting frame, the two ends, left and right of this supporting frame are meshed respectively a left handed screw and a right handed screw are installed, the precession opposite direction of this left handed screw and right handed screw, all install a connection set in the outer end of left handed screw and right handed screw.
And described connection set comprises a link arm coaxially be arranged on left handed screw or right handed screw, draw-in groove is made in the outer end of this link arm, installs a lock bolt that connects draw-in groove on link arm.
And, all mesh a locking mother between supporting frame and connection set of suit on described left handed screw and right handed screw.
Advantage of the present invention and beneficial effect are:
1, because a screw rod is all meshed at these two ends, left and right of device supporting frame of tightly rising, and the outer end of these two screw rods all installs a connection set, and these two connection sets are respectively used to connect chain and hull, and therefore rotating this device that tightly rises is the elasticity of capable of regulating chain.
2, the left handed screw of installing due to the supporting frame two ends and the precession opposite direction of right handed screw, therefore rotary support frame can make two screw rods outwards move simultaneously or move inward simultaneously, not only can reach the purpose of rapid adjustment chain elasticity, and very convenient laborsaving.
3, locking is installed on this screw rod of device of tightly rising female, so screw rod can arbitrarily not rotate and mobile, guarantee that this device stable connection that tightly rises is good.
4, the present invention is a kind of reasonable in design, simple in structure, easy to use, device that tightly rises that connective stability is high, and uses this device that tightly rises can the quick adjustment chain or the elasticity of other links, increases work efficiency, and alleviates labor strength.
The accompanying drawing explanation
Fig. 1 is plan view of the present invention.
Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of chain elasticity rapid adjustment device that tightly rises, comprise a supporting frame 3, the two ends, left and right of this supporting frame are meshed respectively a left handed screw 4 and a right handed screw 5 are installed, the precession opposite direction of this left handed screw and right handed screw, and this left handed screw and right handed screw coaxial setting usually.
In the outer end of left handed screw and right handed screw, a connection set all is installed, this connection set comprises a link arm 2 coaxially be arranged on left handed screw or right handed screw, draw-in groove is made in the outer end of this link arm, the shape of this draw-in groove is not limit, and installs a lock bolt 1 that connects draw-in groove on link arm.On left handed screw and right handed screw, all engagement is set with a locking mother 6 between supporting frame and connection set.
Claims (3)
