Abstract

The invention provides a grab hook capable of being controlled to retract at the distance. The grab hook is mainly formed by a hook handle, a hook gripper and a control mechanism, wherein the control mechanism can control retracting and stretching of the hook gripper at the distance. The hook gripper is movably connected with the hook handle. A locking sliding block is arranged inside the hook handle. A pull rod is arranged on the lower portion of the locking sliding block. A spring is arranged on the outer portion of the pull rod. The lower end of the pull rod is connected with a control rope. The lower end of the hook handle is connected with a stress rope. The grab hook is simple in structure, convenient to carry when not in use, good in safety performance, reliable in locking performance of the hook gripper in use, capable of controlling to retract at the distance where an object is grabbed, and high in practical value.

Description

A kind of grapple that can control withdrawal at a distance

Technical field

A kind of grapple that can control withdrawal at a distance of the present invention relates to the human lives must the field.

Background technology

The grapple of climbing to a higher point and using, the flying tiger pawl that is commonly called as among the people is ancient a kind of weapons and the tool of production of China, and existing grapple is comprised of a neck of hook and 3 to 4 hooks basically, and the neck of hook and hook are rigidly connected, and what be connected with the neck of hook is a rope.During use, grapple is thrown out, relied on hook, hook trees, rock etc., the people catches rope to climb.Several years, the size of its profile and hook are several to be changed to some extent according to specific instructions for use, but its basic shape and operation principle are almost without any innovation.

The user of this grapple generally believes, because being to be rigidly connected between hook and the neck of hook, carries inconvenience, can only hang over user's loins, or hangs over the knapsack side, when occurring the fortuitous event such as falling down, slip, often occurs stabbing or scratch personnel situation.Simultaneously, after use finishing, be difficult to regain at a distance from its trees of hooking, rock below, if the people can not climb the place of hook knot, this grapple has just again been got to be got off, so " the donkey team " of outdoor mountain-climbing, exploration is can only several of multi-bands standby.

Summary of the invention

Can not regain a long way off and carry unsafe deficiency in order to overcome existing grapple, requirement according to the outdoor enthusiast, the present invention proposes a kind of grapple that can control withdrawal at a distance, can control a long way off grapple and regain, use flexibility and reliability, hook can fold, easy to carry, grapple of the present invention mainly is comprised of the neck of hook, hook and control hook jack, it is characterized in that: the neck of hook and hook are flexibly connected, and the controlling organization of controlling the hook folding and unfolding at a distance is arranged on the neck of hook.

The specific embodiment

In Fig. 1, hook 8 roots have a pin-and-hole, a pin-and-hole is arranged at the neck of hook 3 tops, and the pin-and-hole of the pin-and-hole of hook 8 and the neck of hook 3 is movably connected by bearing pin 7, in the neck of hook 3 inside, locking sliding block 6 is installed, pull bar 2 is installed in the bottom of locking sliding block 6, the outside mounting spring 4 of pull bar 2, and rope 1 is controlled in pull bar 2 lower ends connections, the neck of hook 3 lower ends connect stressed rope 9, bearing pin 5 and locking sliding block 6 secure fit.

(do not see Fig. 1) when grapple does not use, control rope 1 at releasing orientation, under the effect of spring 4, the root of hook 8 is withstood in locking sliding block 6 upper ends, hook 8 is locked at the position of the neck of hook 1, and in the grapple carrying process, hook 8 can oneself not open; When need to using, grapple (sees Fig. 2), pull and control rope 1, driving locking sliding block 6 Compress Springs 4 by pull bar 2 moves down, move hook 8 behind the operating position with hand, unclamp and control rope 1, under the effect of spring 4, move on locking sliding block 6 with hook 8 root stationary planes and coordinate, hook 8 namely is in the duty of locking; When needs make the grapple disengaging be grabbed object (seeing Fig. 3), grapple was hooked in by hook 8 and was grabbed on object this moment, unclamp stressed rope 9, pull and control rope 1, drive locking sliding block 6 Compress Springs 4 by pull bar 2 and move down, locking sliding block 6 breaks away from hook 8 root stationary planes, grabbed object and controlled under rope 1 effect both, hook 8 opens to break away from is grabbed object, continues to pull tricing line rope 1, can be grabbed underbelly at quilt and regain grapple at a distance.

Embodiment two:

In Fig. 4, hook 8 roots have a pin-and-hole, and a pin-and-hole is arranged at the neck of hook 3 tops, and the pin-and-hole of the pin-and-hole of hook 8 and the neck of hook 3 is movably connected by bearing pin 7, in the neck of hook 3 inside, electromagnet 11 is installed, and the moving iron core 10 of electromagnet plays the effect of locking sliding block 6 in Fig. 1, and the bottom of electromagnet 11 is equipped with battery 12, in the bottom of battery 12, circuit connecting wire 13 is arranged, circuit connecting wire 13 penetrates the inside of stressed rope 9, and is connected with gauge tap 14, the neck of hook 3 stressed ropes 9 of lower ends connection.

When grapple did not use, under the effect of electromagnet 11 inner springs, the root of hook 8 was withstood in the moving iron core of electromagnet 10 upper ends, hook 8 is locked at the position of the neck of hook 3, and in the grapple carrying process, hook 8 can oneself not open; When grapple need to use, move hook 8 with hand and make it be in the operating position, the moving iron core 10 of electromagnet this moment moves under the effect of electromagnet inner spring, coordinates with hook 8 root stationary planes, and hook 8 namely is in the duty of locking; When needs make the grapple disengaging be grabbed object, press gauge tap 14, connect electromagnet 11 power supplys, the moving iron core 10 of electromagnet moves down, and the moving iron core 10 of electromagnet and hook 8 root stationary planes break away from, and pull stressed rope 9, grabbed under object and stressed rope 9 effect both, hook 8 opens to break away from is grabbed object, continues to pull bearer cable rope 9, can regain grapple at a distance below being grabbed object.

Embodiment three:

In Fig. 5, hook 8 roots have a pin-and-hole, a pin-and-hole is arranged at the neck of hook 3 tops, and the pin-and-hole of the pin-and-hole of hook 8 and the neck of hook 3 is movably connected by bearing pin 7, in the neck of hook 3 inside, electromagnet 11 is installed, the moving iron core 10 of electromagnet plays the effect of locking sliding block 6 in Fig. 1, and the bottom of electromagnet is equipped with battery 12, and the bottom of battery 12 is equipped with remote control reception control device 15 and remote control reception antenna 17, is furnished with in addition remote control transmitter 17, the neck of hook 3 stressed ropes 9 of lower ends connection.

When grapple did not use, under the effect of electromagnet 11 inner springs, the root of hook 8 was withstood in the moving iron core of electromagnet 10 upper ends, hook 8 is locked at the position of the neck of hook 3, and in the grapple carrying process, hook 8 can oneself not open; When grapple need to use, move hook 8 with hand and make it be in the operating position, the moving iron core 10 of electromagnet this moment moves under the effect of electromagnet inner spring, coordinates with hook 8 root stationary planes, and hook 8 namely is in the duty of locking; When needs make the grapple disengaging be grabbed object, press remote control transmitter 17, by remote control reception antenna 17 and remote control reception control device 15, connect the circuit of battery 12 and electromagnet 11, the moving iron core 10 of electromagnet moves down, the moving iron core 10 of electromagnet and hook 8 root stationary planes break away from, pull stressed rope 9, grabbed under object and stressed rope 9 effect both, hook 8 opens to break away from is grabbed object, continue to pull bearer cable rope 9, can regain grapple at a distance below being grabbed object.

The present invention is simple in structure, and is easy to carry when not using, and security is good, and the hook locking property is reliable in use, and can control in the distant place of being grabbed object and regain, and practical value is high.
