The parasols base
Technical field
The utility model relates to outdoor large fixed shading umbrella, relates in particular to a kind of parasols base.
Background technique
The fixing out of doors large-scale parasols that uses is eaten wind because of its head very Da Yi, and it is poorer especially to hang umbrella stability.For the base of aspiring for stability just needs very heavy or ballast, just can make whole umbrella stable.The parasols base of general structure exists and cannot regulated at will bear a heavy burden, and is difficult to stronger adhering to ground; Whole overweight umbrella, problem such as can not arbitrarily move.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of parasols base is provided, and it can not only regulated at will bears a heavy burden to reach with ground the best and adheres to, and conveniently moving.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of parasols base, it is characterized in that: be divided into independently some separately blocks in the base, base protection sleeve is supporting with it to be covered on base, and base is provided with scalable universal wheel unit in four jiaos of holes.
Described scalable universal wheel unit is made up of flexible screw rod, flexible screw holder and universal wheels, and universal wheels and flexible screw rod are connected and fixed, flexible screw rod and flexible screw holder screw-thread fit, and flexible screw holder is fixed on the base.
Described universal wheels is by fixing frame, pad, steel ball, instead spend rivet, block board, wheel to form, based on fixing frame, on steel ball is arranged on fixing frame in the annular groove, screw rod insertion fixing frame center hole stretches; Under have steel ball with the block board holder, serve as that axle is movable fixing in the fixing frame groove with wheel with anti-colored rivet, instead spend the rivet afterbody with pad card jail.
Described flexible screw rod upper end with is connected pole connection, connect pole upward connection shakes the hand.
Be stamped the sheath tegillum on the flexible screw hole on the described base protection sleeve.
The beneficial effects of the utility model are: available sand or water freely increase and decrease heavy burden in base; By manual tune, when base fixedly the time,, allow base land with universal wheels retraction base inside, increase gravity; When moving when transposition, with the universal wheels protuberate basic unit, four universal wheelss are kiss the earth together, can one the people be pushed into stably and want the position of placing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model general assembly structural drawing.

Embodiment
Referring to accompanying drawing, rectangular base 4 centers are the hole of grafting parasols umbrella post, are that radiation is divided into independently some separately blocks in the center base 4 with this through hole, are provided with four through holes that are used for fixing universal wheels 7 at corner location; Base protection sleeve 3 centers are that the through hole corner location of grafting parasols umbrella post is provided with four through holes that are used for socket connection pole 2, and base protection sleeve 3 covers on base 4 supporting with it.The internal thread that flexible screw holder 9 has and flexible screw rod 8 cooperates, flexible screw rod 8 changes in the flexible screw holder 9, the hole of passing on the flexible screw holder 9 with 4 groups of socket head screws and nut 6 is fixed on the base 4, every flexible screw holder 9 can bear the gravity of 100Kg, four altogether; Whole universal wheels 7 and flexible screw rod 8 are inserted in base 4 respective aperture, the sand or the water of the constant weight of packing in the independently some blocks of base 4 as required then cover base protecting cover 3, cover umbrella shank sheath tegillum 5 more again.
Universal wheel component such as flexible screw rod 8, fixing frame 10, pad 11, steel ball 12, anti-colored rivet 13, block board 14, wheel 15 are assembled into scalable universal wheels 7 devices.It is based on fixing frame 10, on have in the annular groove of steel ball 12 on fixing frame 10, flexible screw rod 8 inserts fixing frames 10 center holes, the flange clad of its underpart is on steel ball 12; Under have steel ball 12 useful block boards 14 holding in the palm, block board 14 is fixed with flexible screw rod 8 lower ends, it serve as that axle passes center hole that wheel 15 is placed in fixing frame 10 rectangle grooves with anti-colored rivet 13, instead spends rivet 13 afterbodys firm with pad 11 cards.
During use, when base 4 will be mobile, can open base protection sleeve tegillum 5, hexagonal connects in the top that pole 2 puts in flexible screw rod 8 with connecting, and will shake the hand 1 to be inserted in and to connect pole 2, rotation in the direction of the clock again, up to the enough distances of universal wheels 7 protuberate basic units, secondly the whole protuberate basic unit of four universal wheelss 74 is identical distance, and require four universal wheelss 7 all will be on a relative plane, whole like this heavy burden boosts will be steady relatively.After arriving specified position, utilize again and connect pole 2, shake the hand 1 rotation counterclockwise in four universal wheelss, 7 whole retraction bases 4, add the weight of sand in the independently some blocks of base 4 or water, can with the heavy burden on the base 4 steadily be fixed on the ground.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle; can also make some distortion and improvement, these also should be considered as belonging to protection domain of the present utility model.
