A kind of Alcula type parasols support base
Technical field:
The present invention relates to rain gear technical fields, and in particular to a kind of Alcula type parasols support base.
Background technology
Parasols fixes on the ground, need to stand and expose to wind and rain and be firm.The general practice, user is by parasols
The bottom of central strut plug on the ground, whether the fixation of parasols reliable, is plugged in ground by central strut
The soft or hard degree of depth and ground soil property.However, the umbrella cover that parasols plays sunshade is located at the top of central strut, it is
The stability of entire parasols is improved, the producer can aggravate the weight of central strut, the especially weight of central strut bottom, but
It is that this can increase the burden that user carries parasols.

On be arranged with compression spring 192;The outboard end of compression spring 192 is fixed on the inner side end for sliding spacing ring 122, inner end is fixed on pressure
In the end face outside of spring mounting ring 191;The inner end of limited post 19 is shaped to hemispherical.
As shown in Figure 1, Figure 3, the upper surface sideline of upper support seat 11 is shaped to rounded corner.
The operation principle of support base:
When support base is fixed:The lower support seat 12 of support base 10 is plugged in pit 20 first;Then sunshade
The umbrella handle 30 of umbrella plugs in limiting slot 112;Then it drives driving central shaft 131 to rotate by drive hole 1320, drives center
Axis 131 drives driving gear 13 to rotate, and driving gear 16 drives driven gear 14 to rotate, with the rotation of driven gear 14, water
Flat drive rack 15 moves horizontally from inside to outside;Horizontal drive rack 15 drives gear 16 to drive hook central shaft by hook
161 rotations, the claw that hook central shaft 161 drives hook 17 to become vertical state and hook 17 from horizontality are resisted against limit
On the upper surface of position ring 31, such umbrella handle 30 is fixed, i.e., parasols is fixed;Center threaded rod is driven during driven gear 14
142 rotations, center threaded rod 142 drive lifting supporting block 18 to rise along a pair of of guide post 121, rise in lifting supporting block 18
Its conical surface pushes limited post 19 to be inserted into from inside to outside in the soil of 20 surrounding of pit in the process, and such support base 10 is fixed;
When support base is taken out:Counter-rotating is only needed to drive central shaft 131, transmission when being fixed in this way according to support base
Principle, hook 17 become horizontality from vertical state, are hidden in hiding slot 111, and limited post 19 is in the effect of compression spring 192
Under be retracted into lifting groove 120.
The above content is only the better embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to this hair
Bright limitation.
