Abstract

The invention discloses a self-locking foot loop which comprises a foot climbing device 1, an upright rod 2 and a base 3, wherein the food climbing device 1 comprises a pedal plate 11, a sliding lock 12 and an anti-skidding rubber mat 13. According to the self-locking foot loop, by using a lever effect and a self-locking phenomenon in mechanics, the sliding lock is fastened and buckled on the upright rod by means of the weight of a human body to generate a relatively great friction force, and the foot climbing device generates a self-locking phenomenon and is tightly buckled on the upright rod, thereby allowing a user to easily climb; the gravity born by the foot is reduced when the foot rises, and thus a buckle is automatically loosened. Because the self-locking foot loop is vertically placed when being used, the capability of bearing the gravity is enhanced, so that a climber stably stands to facilitate holding of the upright rod; the self-locking foot loop has the advantages of light weight, high strength, good toughness, convenience, flexibility, safety, reliability and the like, and is convenient to carry; meanwhile, by adopting a three-leg base, the self-locking foot loop is easily close to a wall surface so as to be conveniently used under the condition of no wall surface support; the self-locking foot loop is an ideal climbing tool, and can be widely applied to climbing operation in daily life for buildings or families.

Description

Self-locking pin is climbed

Technical field

The present invention relates to one to ascend a height utensil, is that a kind of self-locking pin is climbed specifically.

Background technology

During by the operation of wall ladder, because ladder tilts, must hold by both hands, centre of body weight will remain on two cleat stanchion central authorities, and therefore health often easy disequilibrium, causes danger; The gross weight tilted when making to bear operating personnel and entrained instrument, material climbing by wall is very limited; When use is done by wall ladder work, the oblique angle on ladder and ground is about 60 degree, can't reach metope at ladder low side, reach, people can only move ladder by descending stair, and easily skid in ladder lower end and ground, therefore must strengthen monitoring, workman can not separate operaton, someone must hold up and keep time especially less by terraced gradient, prevent from operating personnel's slave ladder is fallen down, accidentally will cause high-altitude tumble injury accident; When smooth hard ground uses ladder, gum cover or rubber cushion to be added at foot of ladder, when dirt floor uses ladder, foot of ladder will install iron point additional, therefore make troubles to operation.

Although double ladder is practically applicable to not use by the place of wall, greatly, junction easily loosens, disconnection for consumptive material, heaviness, space occupy-place, easily causes two framves separately to hurt sb.'s feelings.

Summary of the invention

In sum, a kind of self-locking pin is the object of the present invention is to provide to climb.

The object of the invention is to be realized by following technology:

The present invention climbs 1 by pin, up-and-down rod 2 and base 3 form.

1, pin is climbed 1 and is comprised pedal 11, sliding lock 12 and antiskid glue cushion 13.Pedal 11 and sliding lock 12 orthogonal, sliding lock 12 is at upper angle, a left side (or right) for pedal 11, and they are one-body molded, and each one of left and right pin, can slide freely up and down on up-and-down rod 2.Sliding lock 12 tubular, open along its length and meet, through up-and-down rod 2 during use, open in the draw-in groove meeting and be stuck in up-and-down rod 2, its inwall has upper and lower antiskid glue cushion (or the inner side of up-and-down rod is provided with stair-stepping anti-slop serrations), upper antiskid glue cushion is in the outside of up-and-down rod 2, and lower antiskid glue cushion is in the inner side of up-and-down rod 2.

2, up-and-down rod 2 forms by several sections, and every section all can connect and form by wound packages, to meet the demand of ascending a height of differing heights, vertically there is draw-in groove its middle part above, and sliding lock 12 is stuck in wherein can be static or slide up and down, its lower end and base 3 one-body molded.

3, base 3 is stable tripod type, and its tripod length can be stretched, to be applicable to rugged various ground.

Principle: the present invention utilizes leverage, by human body own wt, makes sliding lock be held on up-and-down rod, produces larger frictional force, thus makes people be easy to climb; Gravity because pin bears when people lifts pin reduces, and button unclamps automatically.It is the locking phenomenon that make use of in mechanics, if when people stands on pedal, people to the pressure of pedal and up-and-down rod to the position namely acting on the Q that makes a concerted effort of the active force that pin is climbed with joint efforts of pedal horizontal active force within angle of friction N, then no matter how large this power is, always have a whole resistance R and up-and-down rod balancing with it with joint efforts the horizontal applied force of sliding lock and frictional force straight up, object keeps static; Otherwise if the position of the Q that makes a concerted effort of active force is outside angle of friction N, then no matter how little this power is, and object also can not keep balance.In other words, act on the different gravity on pedal, all can produce equilibrium conditions and locking phenomenon occur.It is irrelevant with active force size and relevant with angle of friction.

Feature: the present invention is vertical owing to vertically putting when using, carrying gravity strengthens, therefore climb people to stand and be reliablely convenient to handrail, have lightweight, intensity is high, good, the light and flexible of adjustability, the advantage such as safe and reliable, easy to carry, and adopt 3 leg bases, easily close to metope, especially can when without easy to use when wall face supporting, be the ideal tools of climbing, electric power can be widely used in, post and telecommunications circuit is ascended a height, also can be used in building or family daily life.

Detailed description of the invention

The object of the invention is to be realized by following technology:

When using of the present invention, both feet respectively put one " pin is climbed ", the body wt of people of ascending a height is applied to pin by pin and climbs up, because footmuff is at pedal C place, A, B 2 is stuck in the lower inner side of up-and-down rod and upper outside, when regarding A point as fulcrum, the suffered gravity of C point makes B point increase the normal pressure of bar, thus the quiet frictional force of B point to bar is increased, equally, A point is also pressed on bar, at A, when B 2 has antiskid glue cushion (or the inner side of up-and-down rod is provided with stair-stepping anti-slop serrations), ensure that the position of the Q that makes a concerted effort acting on the active force that pin is climbed is within angle of friction, then no matter how large this power is, always there is a whole resistance R and up-and-down rod balancing with it with joint efforts the horizontal applied force of sliding lock and frictional force straight up, object keeps static, pin climbs generation locking phenomenon, also by coordinating the material of the contact surface between up-and-down rod and sliding lock to realize self-locking, because angle of friction is also the physical quantity representing material friction character.C place is larger by gravity, and what A, B point glided may be less, and the weight of the people that ascends a height is climbed by pin with regard to an available pin and remained on bar, climb when the pin on people's left foot of ascending a height and be set to position higher on bar, and body weight is moved on on left foot, when climbing support body weight with the pin of left foot, right crus of diaphragm pin is climbed and just upwards can be mentioned with pin, A, B point leaves up-and-down rod, at this moment sliding lock does not have the some D of antiskid glue cushion, E contacts with up-and-down rod, stiction reduces greatly, the position of the Q that makes a concerted effort of active force is made to have dropped on outside angle of friction, then no matter how little this power is, also balance can not be kept, therefore static sliding lock is impelled to slide, left and right is alternately constantly repeated, just can climb to masthead like a cork, similar also can slide from masthead.
