Abstract

The utility model relates to a tent fitting part, in particular to an elliptical rod ground anchor which comprises an anchor sheet, a loop bar, a rotating shaft, rotating wings and a draw hook, wherein the rotating shaft is positioned in the loop bar to movably match with the loop bar, two sides at the top end of the rotating shaft are provided with the rotating wings, the top face of the rotating shaft is provided with the draw hook integrated with the top face, the lower end of the rotating shaft is provided with the anchor sheet integrated with the rotating shaft, the anchor sheet is positioned in a groove arranged at the side of the loop bar, the loop bar is a column body with an elliptical cross section, the lower end of the loop bar is shaped as a cone, and the anchor sheet is shaped as an ellipse. The utility model can play a role of effective anchoring effect, and can be firmly fixed even on the yielding ground; moreover, the operation is very convenient and labor-saving when the tent fitting part is installed and taken out.

Description

Oval shaft-like earth anchor

Technical field

The utility model relates to a kind of tent accessory, particularly relates to the shaft-like earth anchor of a kind of ellipse.

Background technology

When people built tent, the mode that the backguy that is connected with ground is set on its several summits guaranteed the steadiness of tent usually, and the effect of pull wire grounding nail is most important.Tent has mobile strong feature, installs and withdraws conveniently in order to make tent, and the tent grounding nail also need possess the characteristic that can conveniently take out except easy for installation, anchoring is firm.And these 3 often exist certain contradiction, and therefore existing tent grounding nail is difficult to satisfy simultaneously this 3 requirements.

For example the patent No. is that 91200576.9 name is called " earth anchor that is used for fixing Collapsible buildings such as tent or mast " and discloses a kind of device that utensil is fixed on ground, it comprises a tip of a root head steel plate, what fix several hangnail steel wires on it and a swing thereon is to hang the steel wire ring 3 that stay cord uses to form, and it is sent into underground with drill rod and iron hammer.This product has two shortcomings: the one, when reusing because of there being hangnail inconvenience to extract, the 2nd, having when hangnail plays fixation and upwards becoming flexible the gap.

For example the patent No. is that 03255887.2 name is called " a kind of tent and direct rod shape object ground fixator ", it is characterized in that utilizing three cylinders to follow closely and improve its stability and adhesive power, because but every cylinder is followed closely the architectural feature that does not all have anchoring, therefore when external broach was big, three cylinder nails still had the possibility that is pulled away ground.

The utility model content

The utility model is for solving the deficiencies in the prior art, the oval shaft-like earth anchor that a kind of effectively fixedly tent pull wire is provided and can conveniently extracts.

The scheme that solves the utility model technical problem is: oval shaft-like earth anchor is made up of anchor sheet, loop bar, rotating shaft, the rotation wing and drag hook, wherein, rotating shaft is arranged in loop bar, is in active relationship with loop bar, and there is the rotation wing both sides, rotating shaft top, have on the rotating shaft end face and be the drag hook of one with it, the lower end of rotating shaft is to be the anchor sheet of one with rotating shaft, and the anchor sheet is arranged in the groove that the loop bar side is opened, and loop bar is that cross section is oval column, the loop bar lower end is taper, and the anchor sheet is oval.

Fixedly during tent pull wire, only need earlier backguy is tied up on the drag hook, the more shaft-like earth anchor of ellipse is hammered into dirt bed, the twisting rotation wing makes rotating shaft drive anchor sheet half-twist then, and the anchor sheet just stretches out from the groove of loop bar side, has played anchorage effect; In the time of the shaft-like earth anchor of ellipse need being taken out from earth, only need 90 ° of anchor sheet opposite spins, in the groove of anchor sheet withdrawal loop bar side, oval shaft-like earth anchor can be extracted easily.

Adopt such scheme, can reach following effect:

1. because the mooring drag sheet can stretch out in the horizontal direction of below ground, so just play effective anchoring effect, even in soft soil or the friction factor of shell nail and soil when very little, grounding nail also can firmly fix on the ground.

2. can stretch easily owing to the mooring drag sheet, therefore when installing and take out ground, very convenient, laborsaving.

Description of drawings

Fig. 1 is in the structural representation of anchoring status for oval shaft-like earth anchor;

Fig. 2 is the A-A sectional drawing of Fig. 1;

Fig. 3 is the B-B sectional drawing of Fig. 1.

Among the figure: 1. the wings 5. drag hooks are rotated in 3. rotating shafts 4. of anchor sheet 2. loop bars

The specific embodiment

The utility model will be further described below in conjunction with drawings and Examples.

Oval shaft-like earth anchor is made up of anchor sheet 1, loop bar 2, rotating shaft 3, the rotation wing 4 and drag hook 5, wherein, rotating shaft 3 is arranged in loop bar 2, is in active relationship with loop bar 2, and there is the rotation wing 4 both sides, rotating shaft 3 top, have on rotating shaft 3 end faces and be the drag hook 5 of one with it, the lower end of rotating shaft 3 is to be the anchor sheet 1 of one with rotating shaft 3, and anchor sheet 1 is arranged in the groove that open loop bar 2 sides, and loop bar 2 is oval column for cross section, loop bar 2 lower ends are taper, and anchor sheet 1 is oval.

Fixedly during tent pull wire, only need earlier backguy is tied up on the drag hook 5, the more shaft-like earth anchor of ellipse is hammered into dirt bed, the twisting rotation wing 4 makes rotating shaft 3 drive anchor sheets 1 half-twist then, and anchor sheet 1 just stretches out from the groove of loop bar 2 sides, has played anchorage effect; In the time of the shaft-like earth anchor of ellipse need being taken out from earth, only need 90 ° of anchor sheet 1 opposite spins, in the groove of anchor sheet 1 withdrawal loop bar 2 sides, oval shaft-like earth anchor can be extracted easily.

Claims

1. the shaft-like earth anchor of ellipse is made up of anchor sheet, loop bar, rotating shaft, the rotation wing and drag hook, it is characterized in that: rotating shaft is arranged in loop bar, be in active relationship with loop bar, there is the rotation wing both sides, rotating shaft top, have on the rotating shaft end face to be that with it the drag hook of one, the lower end of rotating shaft are is the anchor sheet of one with rotating shaft, the anchor sheet is arranged in the groove that the loop bar side is opened, loop bar is that cross section is oval column, and the loop bar lower end is taper, and the anchor sheet is oval.
