Abstract
The utility model discloses an automatic resetting pulley seat for a vigor board. The automatic resetting pulley seat comprises a fixing seat (3) fixedly connected with the vigor board, an inclined wheel fork (7) and a connecting shaft (8); bearings (3 and 5) are correspondingly mounted on an upper bearing support and a lower bearing support of the fixing seat (3); the wheel fork (7) and the fixing seat (3) are connected integrally through the connecting shaft (8) and a retaining screw (1); an annular spring groove (9) is formed on the fixing seat (3); a supporting point (10) is arranged on the annular spring groove (9); a pushing point (6) inserted into the annular spring groove (9) is arranged on the wheel fork (7); the annular spring groove (9) is divide equally by the supporting point (10) and the pushing point (6); a return spring (4) is arranged in the annular spring groove (9) which is divide equally; and one end of the return spring (4) is propped against the supporting point (10), and the other end thereof is propped against the pushing point (6). The utility model with the structure has the advantages of simple and reasonable structure, flexible turning, automatic resetting, power assisting effect, and the like.
Description
Technical field
The utility model relates to a kind of pulley base of vigor plate, particularly a kind of can automatically reset pulley base in motion process.
Background technology
Along with the progress of science and technology and the development of society, people's living standard has obtained obvious improvement, people are when satisfying material requisite, all kinds of characteristic outdoor activity projects more and more are subjected to teen-age favor, as utilize the both feet twisting to drive pulley and rotate, it is exactly wherein a kind of utilizing user's center of gravity to drive the vigor plate that advances again, it is because light, low price, and have characteristics such as body-building, stimulation, challenge, need not also can drive with the feet step on the ground and advance, become the emerging outdoor activity project of teenager as slide plate.The vigor plate to pulley base require high, should have higher mechanical strength, has higher flexibility ratio again, when being disappeared, the torsion that acts on the pulley and bending force in time reset, though the wheel fork of existing pulley base can freely rotate, but do not have automatically reset function, therefore existing pulley base resets dumb when wheel fork rotates, even can produce stuck phenomenon.For this reason, many manufacturers and knowledgeable people have carried out the R and D of fruitful ground, but do not have rational product to emerge so far as yet.
Summary of the invention
In order to solve the problems referred to above that existing vigor plate pulley base exists, the purpose of this utility model has provided a kind of vigor plate simple and reasonable, that turn to flexibly, automatically reset and have power-assisted effect pulley base that automatically resets.
The technical scheme that its technical problem that solves the utility model adopts, it comprises the holder of fixedlying connected with the vigor plate, the wheel fork and the connecting axle that tilt, correspondence is equipped with bearing on the metal (upper seat of described holder, wheel fork and holder link into an integrated entity by connecting axle and fixed screw, holder is provided with the ring spring groove, the ring spring groove is provided with the strong point, wheel is stuck and is provided with the promotion point that inserts in the ring spring groove, the strong point is divided the ring spring groove equally with the promotion point, be respectively equipped with back-moving spring by in the ring spring groove of dividing equally, back-moving spring one end withstands on the strong point, and the other end withstands on and promotes on the point.
Described holder is provided with fixing hole.
After adopting said structure, the utility model has following advantage and effect: when wheel fork is subjected to torsion and bending force in motion process, promotes wheel fork and drive pulley relative fixed seat to a sideway swivel, wherein the back-moving spring compressed energy-storage of a side; When torsion and bending force balance, under the spring force effect of compressed back-moving spring, back-moving spring rotates round about by promoting some promotion wheel fork drive pulley, making wheel fork drive pulley turns to flexibly, and fast automatic resetting, motion can promote the vigor plate and advance fast so repeatedly.
Description of drawings
Fig. 1 is a decomposing schematic representation of the present utility model.
Fig. 2 is the fit structure schematic diagram of holder and back-moving spring.
The specific embodiment
Illustrated in figures 1 and 2, be the automatically reset specific embodiments of pulley base of the new vigor plate of this practicality, it comprises the holder 3 of fixedlying connected with the vigor plate by fixing hole 11, the wheel fork 7 and the connecting axle 8 that tilt, pulley is installed on the wheel fork 7, correspondence is equipped with bearing 3 on the metal (upper seat of described holder 3,5, wheel fork 7 and holder 3 link into an integrated entity by connecting axle 8 and fixed screw 1, wheel fork 7 connecting axle 8 rotations relatively, connecting axle 8 is by bearing 3, but 5 relative fixed seats, 3 rotations, the bottom surface of holder 3 is provided with ring spring groove 9, ring spring groove 9 is provided with the strong point 10, the end face of wheel fork 7 is provided with also can be around the promotion point 6 of ring spring groove 9 rotations in the insertion ring spring groove 9, the strong point 10 is divided ring spring groove 9 equally with promotion point 6, be respectively equipped with back-moving spring 4 by in the ring spring groove of dividing equally 9, back-moving spring 4 one ends withstand on the strong point 10, and the other end withstands on and promotes on the point 6.During motion, under external force, wheel fork 7 drives pulley and does side-to-side movement around center of rotation, promote point 6 promotes both sides about also in motion back-moving spring 4, back-moving spring 4 stretches promotion wheel fork 7 and pulley mutually and resets under the effect of the strong point 10 and promotion point 6, thereby finishes auto-reset function.
Claims (2)
1. vigor plate pulley base that automatically resets, comprise the holder (3) of fixedlying connected with the vigor plate, the wheel fork (7) and the connecting axle (8) that tilt, it is characterized in that: correspondence is equipped with bearing (3 on the metal (upper seat of described holder (3), 5), wheel fork (7) and holder (3) link into an integrated entity by connecting axle (8) and fixed screw (1), holder (3) is provided with ring spring groove (9), ring spring groove (9) is provided with the strong point (10), wheel fork (7) is provided with the promotion point (6) that inserts in the ring spring groove (9), the strong point (10) is divided ring spring groove (9) equally with promotion point (6), be respectively equipped with back-moving spring (4) by in the ring spring groove of dividing equally (9), back-moving spring (4) one ends withstand on the strong point (10), and the other end withstands on and promotes on the point (6).
2. the vigor plate according to claim 1 pulley base that automatically resets, it is characterized in that: described holder (3) is provided with fixing hole (11).
