Description

A kind of parasol is with boring ground formula fixture

Technical field:

The utility model belongs to ground installation fixed support technical field, relate to a kind of parasol with boring ground formula fixture, particularly be a kind of by by hand fixing apparatus being pierced subsurface and, being applied in the fixed support of the article such as parasol, tent or board frame of daily life and rescue occasion at the underground device that struts.

Background technology:

Along with the raising of people's quality of life, the people that self driving is travelled outdoors is more and more, and the utilization rate of parasol and tents is also improving constantly.At present, the fixing way that adds base that adopts mostly of outdoor tent-like article such as parasol, though base can be filled article such as sandstone, filling article may be not easy to find around opening an umbrella; Also some base need not be filled article, but because weight own is too big, has brought inconvenience to carrying; Usually need fixedly thing such as tent and parasol frame in occasions such as the bigger seashore of dust storm, desert, grassland, traditional ground nail or stake formula nail use cumbersome, no matter be aluminum aerofoil profile tent ground nail or triangular aluminium alloy ground nail or elbow tent ground nail, when wind-force is big, be easy to be pulled away ground; In addition, when the automobile hauling-out that will get down hopeless in a quagmire, rescue and relief work and boats and ships holdfast or the like are many, also need stationary rope, in a word, all need to use the lanyard end or the bracing frame of easy portable in real-life all many-sides; Shortcomings such as existing fixed device ubiquity simple in structure, is difficult for during use in depth down, and fixed effect is poor, and tension force is little, and degree of tension is big inadequately.

Summary of the invention:

Goal of the invention of the present utility model is to overcome the shortcoming that prior art exists, seek to design the supporting adn fixing device that a kind of safe and reliable brill ground formula parasol class is provided, pierce in the harder soil by manual, agent structure is that an augers is installed at the top of spiral line type, when device enter underground after, the support claw of inside can be strutted like a cork or regains, the contact point of support claw and round platform as fulcrum, along with the propelling of screw rod, support claw is opened at leisure.

To achieve these goals, agent structure of the present utility model is bilevel bracing type structure, each layer is shaped on three support claws, and 60 ° of levels support claw phase shiftings, agent structure comprise augers, following Rotary-table and last Rotary-table, lower support pawl and upper support pawl, outer tube, inner screw, tight loop, following rectangular slot and last rectangular slot, articulated elements, fixed head and treadle formula rocking handle; Round metal jacket pipe upper end open, the lower end outside cover system tight loop of outer tube, the lower end of outer tube is inboard fixedly to be shaped on augers with tight loop corresponding position reach, augers top ends upside is equipped with the following Rotary-table of reversed structure, be shaped on the lower support pawl that three pawls of even distribution are formed by the articulated elements rotary type that is connected in the space in the outer tube on following Rotary-table top, lower support pawl top is equipped with the last Rotary-table of reversed structure, the top of last Rotary-table is shaped on the upper support pawl, the lower support pawl, last Rotary-table and upper support pawl all are fixed on the screw type inner screw of direct rod shape metal material, the upper inner place of outer tube fixedly is shaped on the fixed head that can make the inner screw string cross and rotate, so that the rotation of inner screw and firm; The top of the screw type inner screw formula that laterally is connected is shaped on treadle formula rocking handle; Three pawl places of corresponding lower support pawl and upper support pawl are shaped on vertical rectangular slot respectively on the sidewall of outer tube, stretch out outer tube when upper and lower support claw rotates and enter in the ground so that inner screw rotates to drive, and whole fixture is stuck in securely; Augers pierces whole device underground like a cork, with the fastening augers of tight loop; Upper and lower support claw overhangs from going up down to prop up the rectangular slot respectively, and following upper support pawl is hinged on respectively on the articulated elements, and articulated elements is enclosed within on the screw type inner screw, and is fixed up and down; During the downward screw propulsion of screw type inner screw, articulated elements moves downward with the screw type inner screw, and does not rotate with inner screw, makes down the upper support pawl slotting on one side downwards, Yi Bian strut outward, more easily struts underground.

The course of work of the present utility model be earlier whole device is pierced by rocking handle underground, then, the rotating threaded shaft type inner screw, upper and lower support claw touches round platform, two-layer up and down support claw is opened along round platform separately, acts on thereby play with grabbing; When retracting device, backward rotation treadle formula rocking handle just can be packed up support claw, more whole device is produced ground.

Support claw of the present utility model is at the underground root system that struts as plant, can play the more firm ground effect of grabbing, and designs two-layer expanding structure, makes that the support of device is more stable, and is easy to carry, can open and can regain, and can use repeatedly; Its overall structure is simple, and principle is safe and reliable, use easy to operate, active force and good fixing effect, the indoor and outdoor that can be widely used in frame boards such as tent, parasol is fixed.
