Abstract
The invention discloses an automatic chain tensioning structure comprising outer link plates, inner link plates, pins, sleeves, rolling posts, grooves, tensioning springs or torsion springs and the like. In other words, one groove used for a pin moving longitudinally is formed in each inner link plate of various existing chains, and one tensioning spring mounted at the rear end of each groove is used for always tensioning the pin automatically. The automatic chain tensioning structure has the advantages that each chain and sprocket are always tensioned automatically, the number for performing tensioning adjustment of the chain cam be reduced effectively, and service life of the chain, the sprocket or other parts can be prolonged greatly; the automatic chain tensioning structure is simple in structure, low in cost and absolutely safe, reliable and practical, is adaptable to optimization, mounting and using various chains, and is worth vigorous promotion.
Description
Technical field
The present invention relates to a kind of chain automatic stretching structure.
Background technique
Existing various chain, due to automatic tensioning functions useless all, so soon will be due to mechanical wear after installing and using automatic lengthening, if do not regulate in time at once and can come off and cause mechanical failure or accidents caused, and also can cause heel and toe wear and reduce its working life to other component owing to often chain being carried out to tensioning adjusting.
Summary of the invention
The object of this invention is to provide a kind of chain automatic stretching structure, be on each inner plate of existing various chains, to design a movable groove in bearing pin front and back, and at the rear end of each groove design and installation one tension spring, bearing pin is carried out to auto-tensioning constantly, make chain and sprocket wheel constantly in auto-tensioning state, prevent that it from becoming flexible and coming off.
Technological scheme of the present invention is such, and chain automatic stretching structure comprises the compositions such as outer plate, inner plate, bearing pin, sleeve, roller, groove, tension spring or torsion spring.
Above-mentioned inner plate be provided with bearing pin can before and after movable groove, rear end design and installation one tension spring of above-mentioned groove, when making this tension spring carry out tensioning constantly to bearing pin and whole chain assembled is carried out to auto-tensioning.
Above-mentioned tension spring can be also that spring glue or other have flexible object.
One torsion spring also can be installed on the bearing pin between above-mentioned outer plate and inner plate it is carried out to auto-tensioning.
Adopt after such scheme, the beneficial effect of chain automatic stretching structure of the present invention is: can allow between various chains and sprocket wheel constantly in auto-tensioning state, can effectively reduce people and chain be carried out to the number of times of tensioning adjusting, greatly extend the working life of chain, sprocket wheel or other component, and structure of the present invention is very simple, cost is very cheap, it is reliable and practical to be perfectly safe, the improvement that is applicable to various chains is installed and used, and is conducive to widely popularize.And the present invention is not limited to above-mentioned best mode; any entity or individual likely expect easily changing or replacing and draw the product of other similar structure under enlightenment of the present invention; no matter but do any change in its shape or structure; every have identical with principle with a application's structure or akin technological scheme; all within protection domain of the present invention; therefore; any employing present principles is improved various automatic chain tensionings and is installed and used; without prior licensing from the patentee, all belong to infringement.
Accompanying drawing explanation
Fig. 1 is wherein a kind of chain mounting spring automatic stretching structure combination principle figure of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Chain automatic stretching structure of the present invention, as shown in Figure 1, comprises the compositions such as outer plate 1, inner plate 2, bearing pin 3, sleeve, roller, groove 4, tension spring 5 or torsion spring.
Above-mentioned inner plate 1 be provided with bearing pin 3 can before and after movable grooves 4, rear end design and installation one tension spring 5 of above-mentioned groove 4, when making 5 pairs of bearing pins of this tension spring 3 carry out tensioning constantly and whole chain assembled is carried out to auto-tensioning.
Above-mentioned tension spring 5 can be also that spring glue or other have flexible object.
One torsion spring also can be installed on the bearing pin 3 between above-mentioned outer plate 1 and inner plate 2 it is carried out to auto-tensioning.
More than show and what describe is basic principle of the present invention, major character and advantage preferred embodiment of the present invention; the technician of the industry should understand; the claims book and specification and embodiment be not in order to limit the present invention; under the impact of spiritual scope principle prerequisite of the present invention, also have various changes and modifications; but any modification of doing, be equal to replacement, improvement etc., within all falling into claims protection domain of the present invention.
Claims (3)
1. chain automatic stretching structure, comprise that outer plate, inner plate, bearing pin, sleeve, roller, groove, tension spring or torsion spring form, it is characterized in that: above-mentioned inner plate is provided with the movable groove in bearing pin energy front and back, rear end design and installation one tension spring of above-mentioned groove.
2. chain automatic stretching structure according to claim 1, is characterized in that: above-mentioned tension spring can be also that spring glue or other have flexible object.
