Description
Technical field
The invention belongs to parasols apparatus technical field, relate in particular to a kind of rotational locking device.
Background technology
Parasols uses extremely extensive at aspects such as people's leisure, amusements; existing parasols structure; except the main chute body; usually also be provided with the rotational locking device of capable of regulating parasols angle; can obtain appropriate shaded effects by this device so that parasols freely adjusting angle reach the purpose that the user need to reach.The rotational locking device pattern of existing parasols is a lot, but has the problems such as complex structure, assembling is loaded down with trivial details, cost is high, production efficiency is low.
Summary of the invention
The object of the invention is to solve above-described technical problem, a kind of rotational locking device is provided, its technical scheme is as follows:
A kind of rotational locking device comprises fixed disk, and described fixed disk top is provided with carrier, is provided with telophragma between described fixed disk and the carrier, and clamping has upper group of ball ball between described telophragma and the carrier; The interior chimeric fluted disc that has of described fixed disk, clamping has lower group of ball ball between described fluted disc and the fixed disk; The side opening of described fixed disk is provided with breach, is fixed with fixed block on the described fixed disk, and described fixed block is connected with pedal assembly by torsion spring, and described pedal assembly is meshed spacing by breach with fluted disc; Described fixed disk, carrier and fluted disc are locked by lock shaft.
Optimal way is that described carrier, fixed disk, telophragma, fluted disc are by the hydro-drawing technological forming.
Optimal way is that the bottom of described fluted disc is provided with packing ring.
Rotational locking device provided by the invention when in use, generally can be fixed with parasols or other mechanical devices on carrier.When needs change parasols angle, use foot-operated firmly pedal assembly, realize that by lever principle pedal assembly and fluted disc break away from rotation under the effect of torsion spring torsion, thereby drive parasols or the rotation of other mechanical devices of being fixed on the carrier.After having arrived the angle that needs when parasols or other mechanical devices, decontrol pedal assembly, so that pedal assembly return under the torsion of torsion spring, thereby so that pedal assembly be meshed with fluted disc spacing, thereby drive parasols or other mechanical device stop of being fixed on the carrier.
Carrier of the present invention, fixed disk, telophragma, fluted disc, fixed block are by the hydro-drawing moulding, and its production cost is low, production efficiency is high, and it is comparatively convenient to assemble, use, safeguard.
Carrier of the present invention, operated by rotary motion has circular orbit, and the center pull and stretch has groove, and surperficial pull and stretch has a plurality of uniform locating holes.
Fixed disk of the present invention, operated by rotary motion has circular orbit, and the side pull and stretch has a plurality of breach, and surperficial pull and stretch has a plurality of uniform locating holes.Fixed block is welded in the fixed disk surface, and pedal assembly and torsion spring are fixed between fixed block and the fixed disk by screw.
Telophragma of the present invention, operated by rotary motion has circular orbit, and the center pull and stretch has projection, and this projection and above-mentioned fixed disk closely cooperate, thereby make fixed disk relative with telophragma static, and both are combined into an organic whole, and designs simplification is just with assembling.
Fluted disc of the present invention, operated by rotary motion has circular orbit, and the outer ring is provided with tooth, and the center pull and stretch has groove.
Above-mentioned circular orbit is for group ball ball and lower group of ball ball in the convenient clamping.
Among the present invention, the effect that upper group of ball ball, lower group of ball ball serve as bearing, and its contact point is many, contact-making surface is large, effectively offsets mechanical load, good stability.
Reasonable in design of the present invention, have advantages of simple structure, good stability, cost is low, production efficiency is high, attractive in appearance, be applicable to the architecture advances of various parasols ex hoc genus anne product.
Description of drawings
The schematic diagram of Fig. 1 invention.
The cut-away view of Fig. 2 invention.
The specific embodiment
Specify embodiment below in conjunction with Fig. 1 and Fig. 2:
A kind of rotational locking device comprises fixed disk 1, and described fixed disk 1 top is provided with carrier 2, is provided with telophragma 3 between described fixed disk 1 and the carrier 2, and clamping has upper group of ball ball 4 between described telophragma 3 and the carrier 2; The described fixed disk 1 interior chimeric fluted disc 5 that has, clamping has lower group of ball ball 6 between described fluted disc 5 and the fixed disk 1; The side opening of described fixed disk 1 is provided with breach 7, is fixed with fixed block 8 on the described fixed disk 1, and described fixed block 8 is connected with pedal assembly 10 by torsion spring 9, and described pedal assembly 10 is meshed spacing by breach 7 with fluted disc 5; Described fixed disk 1, carrier 2 and fluted disc 5 are by lock shaft 11 lockings.
Optimal way is that described carrier 2, fixed disk 1, telophragma 3, fluted disc 5 are by the hydro-drawing technological forming.
Optimal way is that the bottom of described fluted disc 5 is provided with packing ring 12.
Rotational locking device provided by the invention when in use, generally can be fixed with parasols or other mechanical devices on carrier.When needs change parasols angle, use foot-operated firmly pedal assembly, realize that by lever principle pedal assembly and fluted disc break away from rotation under the effect of torsion spring torsion, thereby drive parasols or the rotation of other mechanical devices of being fixed on the carrier.After having arrived the angle that needs when parasols or other mechanical devices, decontrol pedal assembly, so that pedal assembly return under the torsion of torsion spring, thereby so that pedal assembly be meshed with fluted disc spacing, thereby drive parasols or other mechanical device stop of being fixed on the carrier.
