Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
In Fig. 1, a kind of automatic chain tensioning device, including firm banking 4, tightener sprocket 6, adjustable plate 5 and adjusting component,
Tightener sprocket 6 is attached with the adjusting component by the connecting plate 5, and connecting plate 5 and firm banking 4 are hinged.
In some embodiments, component is adjusted to include the screw rod 1 connecting with the connecting plate 5, match with the screw rod 1
Adjusting nut 2 and the elastic parts that is sheathed on the screw rod 1, adjusting nut 2 be used to adjust the compression journey of elastic parts
Degree, regulative mode are to be adjusted by rotary distance of the adjusting nut 2 on screw rod 1.
Elastic parts includes reset spring 3 and the spring base 8 for being set to 3 both ends of reset spring, adjust component with it is described
Firm banking 4 is slidably matched, and as shown in figure 1, adjusting nut 2 is in the left end of reset spring 3, is bonded with the spring base 8 of left end, leads to
It crosses and turns adjusting nut 2 and the length of reset spring 3 can be adjusted.
Referring to Figure 2 to Figure 4, firm banking 4 includes bottom plate 41 and the side plate 42 being axially arranged along the bottom plate 41, i.e. side
Plate 42 is vertically arranged on bottom plate 41, and there are two side plates 42 and is oppositely arranged, and is provided with partition 7 between two side plates 42,
The sliding slot 71 matched with elastic parts is offered on partition 7.Spring base 8 positioned at 3 right end of reset spring is bonded with partition 7,
Screw rod 1 passes through sliding slot 71 and can slide along the sliding slot 71.
Preferably, through-hole 43 is offered on two side plates 42, is provided with connecting rod, the company between two through-holes 43
Fishplate bar 5 is articulated on the connecting rod, and it is motionless state that connecting rod, which is between two through hole 43, and connecting plate 5 can be turned around connecting rod
It is dynamic.
The junction of connecting plate 5 and the tightener sprocket 6 and the junction for adjusting component and the firm banking 4
Junction in triangular shape be distributed, referring to Fig.1, thirdly place junction constitute a triangle that is, under force can make
Connecting plate 5 is obtained to be rotated around connecting rod, and since even junction is to be fixedly connected for other, the adjusting component and chain being connected to
Wheel follows connecting plate 5 to be rotated, and achievees the purpose that automatic adjustment.
Referring to Fig. 4, for the present invention and sprocket wheel chain fit structure schematic diagram, in the present invention, tightener sprocket 6 and extraneous chain
Cooperation, chain are between sprocket wheel, and fit system is, when being worked, first passes through adjusting nut 2 and is adjusted to conjunction
Suitable intensity, in the course of work, due to working for a long time, chain can loosen, and tightener sprocket 6 can be become by the power of chain at this time
It is small, it is influenced at this time by reset spring 3, screw rod 1 can be made to move downward, just connecting plate 5 is driven to rotate clockwise at this time, even
While fishplate bar 5 rotates, but also screw rod 1 up moves, while tightener sprocket 6 is also rotated clockwise, so that itself and chain
Between power return back to the work incipient stage, same reason, when power of the chain to tightener sprocket 6 is excessive, 5 inverse time of connecting plate
Needle rotation, other component are not above-mentioned opposite.Using this mechanism, accurate automatic adjustment is realized.
It is an advantage of the current invention that realizing automatic adjustment chain and chain using the effect of reset spring 3 and connecting plate 5
The rate of tension for taking turns cooperation can effectively prevent chain and be detached from sprocket wheel, ensure that the safety of production.
Only highly preferred embodiment of the present invention is described above, but is not to be construed as limiting the scope of the invention.This
Invention is not only limited to above embodiments, and specific structure is allowed to vary.All protection models in independent claims of the present invention
Interior made various change is enclosed to all fall in the scope of protection of the present invention.
