Description

Parasols 360 degree rotating mechanisms

Technical field

The utility model relates to the base of parasols, is a kind of parasols 360 degree rotating mechanisms.

Background technology

Parasols or title parasol, its a kind of large-scale parachute kit that is mainly used in the anti-direct projection that keeps off the sun of outdoor screening generally is made up of umbrella shank, umbrella bar, umbrella body.At present, the Sunshading umbrella base of market sale can be divided into fixed and rotary two kinds usually.Wherein, fixed umbrella shank is general direct to be inserted and secured on the umbrella bar on the umbrella shank, and its defective is to realize the level 360 degree spinfunctions of parasols.Rotary umbrella shank is mainly used in the umbrella that hangs that the umbrella bar is arranged at umbrella body one side, and by the sunlight direct projection angle that parasols is regulated in level 360 degree rotations, it generally is divided into hand-rail type rotation and foot-operated rotation.Hand-rail type rotation umbrella shank is generally realized the level 360 degree rotations of umbrella bar on umbrella shank by the principle of turbine, scroll bar; Foot-operated rotation umbrella shank generally rotates by level 360 degree of clutch principle control umbrella bar on umbrella shank of gear.As the application number 200920193109.6 that discloses in the Chinese patent literature, on August 20 2009 Granted publication day, above-mentioned umbrella shank rotates the umbrella bar or locking by the gear mouth engagement of pedal assembly from bottom and fluted disc.The ZL patent No. 03228609.0 that and for example discloses in the Chinese patent literature, January 21 2004 Granted publication day, utility model title " Block Umbrella Rotation Angle Self-Locking Device "; This umbrella shank rotates the umbrella bar or locking by the gear mouth of pedal assembly plug fluted disc.But promptly can't the Rotatable umbrella bar after above-mentioned umbrella shank and the umbrella rod lock, its umbrella bar rotating manner is comparatively single; Simultaneously, above-mentioned Umbrella stand structure assembles, production is comparatively inconvenient, stable, security is relatively poor, and production cost is higher.

Summary of the invention

For overcoming above-mentioned deficiency, the purpose of this utility model is the parasols 360 degree rotating mechanisms that a kind of level 360 degree Rotatable umbrella bars are provided to this area, it is single to make it solve existing like product structure function, it is comparatively constant to produce assembling, production cost is higher, stability, the lower technical problem of security.Its objective is and be achieved through the following technical solutions.

A kind of parasols 360 degree rotating mechanisms, this mechanism comprises dish, fluted disc, mid-game, lower wall, the first steel ball group, umbrella bar, umbrella shank lid, punch rivet, cross tile type umbrella shank, pedal assembly, pedal assembly comprises pedal, pedal cover, bilateral torsion spring; Be with the umbrella shank lid in the umbrella bar, the pedal cover is connected with pedal by plus screw, is provided with fluted disc between the bottom of umbrella bar and the cross tile type umbrella shank; Make pedal assembly and fluted disc mesh spacing or break away from by pedal assembly and rotate, thereby make the spacing or rotation of umbrella bar.Its design main points be described lower wall, mid-game, fluted disc respectively punching press be projective table type embedding indent, the top boss face of lower wall is provided with the first steel ball group; Fluted disc is connected with the top boss face of lower wall, and the first steel ball group is held between fluted disc and the lower wall; The external diameter of mid-game is provided with the second steel ball group, and lower wall is inserted in mid-game, and second steel ball is held between lower wall and the mid-game, and lower wall, mid-game, fluted disc, last dish, pole socket are connected as a single entity by at least two above punch rivets; The bottom of described lower wall is provided with the U template, and an end of pedal is articulated in the U template by tubular rivet, and the junction of pedal and U template is provided with bilateral torsion spring, the gear mouth engagement of projection that pedal should be held and fluted disc external diameter; Cross tile type umbrella shank is fixed in by the second socket cap hexagon socket head cap screw in the bottom of lower wall, and the bottom and the pole socket of umbrella bar are connected as a single entity, and pole socket is fixedlyed connected with last dish by the first socket cap hexagon socket head cap screw.The second steel ball group is held between lower wall and the mid-game by punch rivet, and this respective outer side edges first steel ball group is held between lower wall and the fluted disc by the nail that presses, when further having improved by foot-operated assembly and fluted disc disengaging, and stability and security that the umbrella bar rotates.Its operation principle is identical with existing like product, but its lower wall, fluted disc, goes up dish, mid-game by one time punching molded, and its production cost is lower, assembling, maintenance, uses comparatively conveniently, has improved production efficiency.

The outer, top of described lower wall is provided with the first spill circle track of punching press, and the first steel ball group is arranged in the first spill circle track of lower wall; The outer, bottom of mid-game is provided with the second spill circle track of punching press, and the second steel ball group is arranged in the second spill circle track of mid-game.First, second spill circle track is the annular ring recess of punching press, make first, second steel ball group free rolling while in first, second spill circle track by first, second spill circle track, first, second steel ball group is difficult for skidding off first, second spill circle track, has improved this mechanism stability and security.

The protruding end of described pedal is provided with the symmetry projection, and projection is the U font.The biconvex of U font plays design, and the protruding end of pedal and the gear mouth engagement of fluted disc external diameter are further stablized, and locking mode is further firm.

Described umbrella bar adopts I-steel.I-steel had both made things convenient for the fixing of umbrella body connector, increased again the umbrella body weight, improved the firmness of umbrella body, and then improved this mechanism stability and security.

The utility model reasonable in design, easy to assembly, production cost is low, and stability, security is good, easy to use; Be applicable to the various umbrellas that hang, ex hoc genus anne the architecture advances of product.
