Description
Technical field
The utility model relates to a kind of tightening device, is specifically related to a kind of chain stretching device.
Background technology
Chain affects the weight of goods owing to installing manufacturing errors, it is soft that chain can become, and when carrying out the handling of goods, require that chain has certain tensioning degree.Chain conveyer is widely used in industrial circle, and because chain gear there will be the lax phenomenon of chain in the course of the work, carry out tensioning if do not take measures and chain gear efficiency will be caused to decline, even chain is deviate from and cannot be worked.
Utility model content
The purpose of this utility model be to provide a kind of simple and reliable for structure, easily manufactured, regulatory function is effective, stressed better, not yielding and maintaining chain stretching device easily.
The technical solution of the utility model is achieved in that a kind of chain stretching device, comprise support, described support is provided with a guide groove in a welding manner, described guide groove slidably connects the slide block matched with it, one end of described slide block is connected a sprocket wheel axle bed, a sprocket shaft is equipped with in described sprocket wheel axle bed, outside described sprocket wheel axle bed, two ends are installed with the fixed disc for fixed chain wheels axle respectively, the two ends of described sprocket shaft are provided with sprocket wheel, described sprocket wheel walked around by chain, the axis of sprocket wheel is vertical relative to the direction of slip of support with slide block, the other end of described slide block is connected a puller bolt, described puller bolt is arranged in a threaded flange, described threaded flange is fixedly arranged on support in a welding manner.
Further, described guide groove is dovetail furrow, and described slide block is dovetail slide block.
Further, described puller bolt is arranged in one grade of end, and described shelves end and threaded flange lean and arrange.
Further, can a sheathed spring outside described puller bolt, one end of described spring withstands on threaded flange.
The beneficial effects of the utility model are: one group of sprocket wheel of chain, the sprocket wheel of its left and right sides is arranged on slide block by sprocket shaft, this slide block is promoted by puller bolt, it is made to slide in fixing guide groove, sprocket shaft and sprocket wheel are moved along chain tension direction, thus realizes the tensioning of chain.Good looking appearance, structure are simple, convenient for installation and maintenance, regulatory function is effective, better stressed, effectively can solve part deformation and chain and the soft problem of the chain that causes such as naturally extend.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of chain stretching device as shown in Figure 1, comprise support, described support is provided with in a welding manner a guide groove 3, described guide groove 3 slidably connects the slide block 4 matched with it, one end of described slide block 4 is connected a sprocket wheel axle bed 5, a sprocket shaft is equipped with in described sprocket wheel axle bed 5, outside described sprocket wheel axle bed 5, two ends are installed with the fixed disc for fixed chain wheels axle respectively, the two ends of described sprocket shaft are provided with sprocket wheel, described sprocket wheel walked around by chain, the axis of sprocket wheel is vertical relative to the direction of slip of support with slide block 4, the other end of described slide block 4 is connected a puller bolt 1, described puller bolt 1 is arranged in a threaded flange 2, described threaded flange 2 is fixedly arranged on support in a welding manner.By puller bolt 1, slide block 4 can be promoted, make it slide in guide groove 3 with the sprocket wheel axle bed 5 be connected thereon and sprocket shaft, thus realize the tensioning of chain.
Described guide groove 3 is dovetail furrow, and described slide block 4 is dovetail slide block.
Described puller bolt 1 is arranged in one grade of end, and described shelves end and threaded flange 2 lean and arrange.
Can a sheathed spring outside described puller bolt 1, one end of described spring withstands on threaded flange 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
