Abstract

The utility model relates to an automatic anchor comprising an anchor rod (1), a collision rod (3), a restraining ring (7), a first spring (4), a second spring (5) and at least one anchor arm (2), wherein a collision needle (6) is arranged at the top of the anchor rod (1); a cavity (8) with an upward opening is arranged at the top end of the anchor rod (1); all the parts are combined to realize the automatic anchor, so that the anchor arm (2) is at a folding state before the automatic anchor reaches a fixed point from a casting point; after the automatic anchor reaches the fixed point, the anchor arm is automatically expanded to fix; and when the anchor arm (2) is at the folding state, the whole volume of the anchor is small, the automatic anchor can be conveniently cast to more fixed point positions, and the application range is wide.

Description

A kind of automatic anchor

Technical field

The utility model relates to a kind of automatic anchor.

Background technology

Anchor is the instrument for climbing building crawl fixing point, at present, people used modal be the fixing anchor of shape, with the time it is thrown the place that can fix, but this anchor can only be thrown away than also large space competence exertion effect of anchor self, otherwise directly landing, cause and can't be fixed anchor.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of after arriving fixing point, the automatic anchor that can the Automatic-expanding anchor arm be fixed.

The utility model is in order to solve the problems of the technologies described above by the following technical solutions: the utility model has designed a kind of automatic anchor, comprises anchor pole and at least one anchor arm, also comprises lance, confinement ring, the first spring and the second spring; The top of lance is provided with striker, and the top of described anchor pole is provided with the cavity of opening upwards, and lance inserts in cavity with the downward direction of its end, and the second spring is arranged between lance bottom and cavity diapire; Anchor arm tip is movably connected in the top of anchor pole, and anchor arm can be rotated take its end as axle; The first spring is arranged in cavity, and an end of the first spring is connected with the end of anchor arm, and the inwall of the other end and cavity fixes; The surface of described cavity is provided with opening, and confinement ring is enclosed within on anchor pole, and fixes by the lance in opening and cavity, and confinement ring limits the rotation of anchor arm by the buckle that is arranged on anchor arm.

As a kind of optimal technical scheme of the present utility model: also comprise the stay cord ring that is arranged on described anchor pole end.

As a kind of optimal technical scheme of the present utility model: described the first spring housing inserts in described cavity with lance on lance, and an end of the first spring is connected with the end of described anchor arm, and the inwall of the other end and described cavity fixes.

A kind of automatic anchor described in the utility model adopts above technical scheme compared with prior art, has following technique effect:

(1) the automatic anchor of the utility model design, before arrive fixing point, anchor arm is in and closes up state from throwing; After arriving fixing point, can be fixed by the Automatic-expanding anchor arm;

(2) the automatic anchor of the utility model design is not when arriving fixing point, and anchor arm makes the overall volume of anchor diminish for closing up state, is convenient to more fixing point position is arrived in this automatic anchor throwing, and it is wider that the scope of application becomes;

(3) the automatic anchor of the utility model design is provided with the stay cord ring at the end of described anchor pole, is convenient to being connected of rope and anchor.

Description of drawings

Fig. 1 is that a kind of automatic anchor of the utility model design is in structural representation when closing up state at anchor arm;

Fig. 2 is the structural representation of a kind of automatic anchor when anchor arm is in deployed condition of the utility model design.

Wherein, 1. anchor pole, 2. anchor arm, 3. lance, 4. the first spring, 5. the second spring, 6. striker, 7. confinement ring, 8. cavity, 9. opening, 10. buckle, 11. stay cord rings.

The specific embodiment

Below in conjunction with Figure of description, the specific embodiment of the present utility model is described in further detail.

As depicted in figs. 1 and 2, the utility model has designed a kind of automatic anchor, comprises anchor pole 1 and at least one anchor arm 2, also comprises lance 3, confinement ring 7, the first spring 4 and the second spring 5; The top of lance 3 is provided with striker 6, and the top of described anchor pole 1 is provided with the cavity 8 of opening upwards, and lance 3 inserts in cavity 8 with the downward direction of its end, and the second spring 5 is arranged between lance 3 bottoms and cavity 8 diapires; Anchor arm 2 ends are movably connected in the top of anchor pole 1, and anchor arm 2 can be rotated take its end as axle; The first spring 4 is arranged in cavity 8, and an end of the first spring 4 is connected with the end of anchor arm 2, and the inwall of the other end and cavity 8 fixes; The surface of described cavity 8 is provided with opening 9, and confinement ring 7 is enclosed within on anchor pole 1, and fixes by the interior lance 3 of opening 9 and cavity 8, and confinement ring 7 limits by the rotation that is arranged on the 10 pairs of anchor arms 2 of buckle on anchor arm 2.

The automatic anchor of the utility model design, before arrive fixing point, anchor arm 2 is for closing up state from throwing; After arriving fixing point, can be fixed by Automatic-expanding anchor arm 2.

The automatic anchor of the utility model design is not when arriving fixing point, and anchor arm 2 makes the overall volume of anchor diminish for closing up state, is convenient to more fixing point position is arrived in this automatic anchor throwing, and it is wider that the scope of application becomes.

As a kind of optimal technical scheme of the present utility model: also comprise the stay cord ring 11 that is arranged on described anchor pole 1 end.

The automatic anchor of the utility model design is provided with the stay cord ring at the end of described anchor pole, is convenient to being connected of rope and anchor.

As a kind of optimal technical scheme of the present utility model: described the first spring 4 is enclosed within on lance 3, insert in described cavity 8 with lance 3, and an end of the first spring 4 is connected with the end of described anchor arm 2, and the inwall of the other end and described cavity 8 fixes.

The automatic anchor of the utility model design is in the middle of actual application, this anchor from throwing before arrive fixing point, by confinement ring 7 and the buckle 10 that is arranged on anchor arm 2, anchor arm 2 is in closes up state, the anchor overall volume of this moment is little, just can be arrived more fixed point by throwing, and this moment, the first spring 4 is in extended state; When anchor arrives fixing point, effect due to throwing, the striker 6 that is arranged on lance 3 tops can clash into the fixed position, shock makes lance 3 to move to cavity 8 directions, because confinement ring 7 is enclosed within on anchor pole 1, and fix by the interior lance 3 of opening 9 and cavity 8, move so confinement ring 7 is understood with lance 3, and then removed the constraint of 7 pairs of anchor arms 2 of confinement ring; Under the active force of the first spring 4, anchor arm 2 is launched rapidly, and then realized having fixed effect by the anchor arm 2 that launches.For the stay cord ring 11 that is arranged on described anchor pole 1 end, the user can easily be connected to rope on anchor.

The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possess, can also make a variety of changes under the prerequisite that does not break away from the utility model aim.
