The rotary locking device comprises a fixing disc, wherein a carrier is arranged at the top of the fixing disc, a middle disc is arranged between the fixing disc and the carrier, and an upper-group round balls are clamped between the middle disc and the carrier. A tooth disc is embedded in the fixing disc, and a lower-group round balls are clamped between the tooth disc and the fixing disc. The side of the fixing disc is provided with a gap, a fixing block is fixed on the fixing disc and connected with a pedal assembly through a torsion spring, and the pedal assembly is meshed and limited with the tooth disc through the gap. The fixing disc, the carrier and the tooth disc are locked through a locking shaft. The rotary locking device is reasonable in structural design, has the advantages of being simple in structure, good in stability, low in cost, high in production efficiency and attractive, and is suitable for structural improvement of various sunshades and like products.
Description
Technical field
The utility model belongs to parasols apparatus technical field, relates 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 that to adjust the parasols angle; can obtain appropriate shaded effects by this device, make parasols freely adjusting angle reach the purpose that the user need reach.The rotational locking device pattern of existing parasols is a lot, but has problems such as complex structure, assembling is loaded down with trivial details, cost is high, production efficiency is low.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of rotational locking device is provided, and 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 the group of going up ball ball between described telophragma and the carrier; The interior chimeric fluted disc that has of described fixed disk, clamping has group ball ball down between described fluted disc and the fixed disk; The side of described fixed disk offers breach, and fixed block is fixedly arranged 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.
The rotational locking device that the utility model provides when in use, generally can fixedly have parasols or other mechanical devices at 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, make pedal assembly return under the torsion of torsion spring, thereby it is spacing to make that pedal assembly is meshed with fluted disc, thereby drives parasols or other mechanical device stop of being fixed on the carrier.
Carrier of the present utility model, 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 utility model, 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 utility model, 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 utility model, operated by rotary motion has circular orbit, and the center pull and stretch has projection, and this projection and said fixing dish 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 utility model, 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 in the convenient clamping and organizes the ball ball down.
In the utility model, on organize the ball ball, organize the effect that the ball ball serves as bearing down, and its contact point is many, contact-making surface is big, effectively offsets mechanical load, good stability.
The utility model reasonable in design has simple structure, good stability, cost is low, production efficiency is high, attractive in appearance advantage, is applicable to the architecture advances of various parasols ex hoc genus anne product.

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 the group of going up 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 group ball ball 6 down between described fluted disc 5 and the fixed disk 1; The side of described fixed disk 1 offers breach 7, on the described fixed disk 1 fixed block 8 is arranged fixedly, 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.
The rotational locking device that the utility model provides when in use, generally can fixedly have parasols or other mechanical devices at 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, make pedal assembly return under the torsion of torsion spring, thereby it is spacing to make that pedal assembly is meshed with fluted disc, thereby drives parasols or other mechanical device stop of being fixed on the carrier.
