Abstract

The utility model discloses a flexible automatically-flexing safety foot fastener. A square tube of the prior foot fastener is levelly welded with a bearing bracket (4) having a large square hole, a thrust ball bearing (10) is arranged in a bearing groove of the bearing bracket, a square-round screw rod (1) is sleeved with the thrust ball bearing (10) and a bearing bracket (2) having a small square hole sequentially, and then is screwed with a nut rubber wheel (3), the square-round screw rod (1) is inserted in the square hole of the bearing bracket (4) having the large square hole and is levelly and integrally welded with the square tube of the foot fastener, and the upper and lower sides of the bearing bracket (2) having the small square hole and the bearing bracket (4) having the large square hole are fixedly connected with each other through a bearing bracket connecting sheet (8). When the nut rubber wheel (3) is adhered to the surface of a concrete pole body and moves and rubs upwards and downwards to rotate, the square-round screw rod (1) can be driven to move back and forth so as to realize the function of flexible automatically-flexing, thereby achieving the aims of flexible and convenient use, comfort, safety and reliability.

Description

A kind of flexible automatic flexible safe climbers

Described technical field:

The utility model relates to a kind of climbers that bar uses of stepping on, the flexible automatic flexible safe climbers of especially a kind of energy.

Background technology:

People climb the climbers that cement electric pole uses at present, the weak point that it exists is because cement electric pole is the thick down thin cylinder of, people are using existing climbers up and down during electric pole, in order to make climbers and electric pole keep the degree of firm fastening, can only pull somewhat inflexible motion bar is regulated, the gap of adjusting is not quite just little, be difficult to keep corresponding suitable degree with electric pole, moreover when adjusting, break away from electric pole with the trick that intersects again and carried out, give people about bring loaded down with trivial details and unsafe factor during electric pole; Pedal is too short to be caused human weight all to make to be added on the double-legged palm, to have made both feet extremely suitable sleepy; Because of having only a cingulum to be worn on the instep, usually cause the difficult situation that comes off accidentally again to people.

The utility model content:

In use there is the deficiency that to regulate its bore automatically and very easily come off etc. in order to overcome existing climbers, the purpose of this utility model provides a kind of flexible automatic flexible safe climbers, these climbers can be adjusted the climbers caliber size automatically in stepping on the bar operation process, keep suitable fastening degree with electric pole all the time.

The technical scheme that its technical problem that solves the utility model adopts is: on the basis of existing climbers, slightly be square placing in the square hole movable expansion link partly to be processed into and with the alternate octahedral body of screw (disc has tap) circumference (being called for short the circumference lead screw), left foot is buckled and is suitable silking, right crus of diaphragm is buckled and is the wire inversion line, thickness should with intert in square hole can only before and after move flexibly, non-rotatable being advisable.Reprocess a wheel in its supporting inner nut overcoat rubber ring, left foot is buckled and is suitable silking, right crus of diaphragm is buckled and is the wire inversion line, the logical nut rubber wheel that abbreviates as, at the same together big thrust ball bearing groove concentric of this each processing of place, two planes of taking turns with the nut circular hole, make two inboards and nut rubber wheel thrust ball bearing groove corresponding square holes bearing bracket stand in addition, square hole and square tube endoporus are with big, another square hole is more bigger, can be enclosed within on the climbers square tube and concordant it is welded on one, the circumference lead screw of so far band being colluded pierce into the square hole of square tube endoporus with big bearing bracket stand in, in the bearing groove at place, nut rubber wheel two planes, adorn a thrust ball bearing respectively, and be screwed on the circumference lead screw, be inserted into the square hole bearing bracket stand and climbers square tube top is welded within the square hole of one, respectively its diaxon bolster tie point up and down is fixed together with nut with two bump contacted chips, one end of two bump contacted chips has two circular holes of wearing nut respectively, the other end has two microscler nut holes respectively, is convenient to adjust the gap and the degree of flexibility of two thrust ball bearings.So forming the nut rubber wheel promptly is subjected to the restriction of diaxon bolster again can be in this flexible rotation, people make short its rotation of nut rubber wheel card body of rod mantle friction when up and down only depending on two pin to move up and down during cement electric pole with these climbers, order about the expansion link that is enclosed within band screw within the square tube and do back and forth movement, just can play the effect of automatic control climbers openings of sizes, opening evenly dwindles when being upper boom, bore increases gradually during following electric pole, and can keep suitable tightness with the electric pole body all the time.Increase the length of pedal, release human body gravity all makes and adds the drawback that acts on two forefoots; Use instead and automatic cingulum of heel place addition the front, can be with firm the tying up on the both feet of climbers, so that finish flexible automatic flexible function smoothly, the beneficial effects of the utility model are: by the cooperation utilization of above-mentioned each assembly, played the function that has more flexible automatic steady adjusting climbers openings of sizes with pin band hand, also no longer worry, have more flexible, comfortable, safe and reliable purpose thereby reach to use for climbers very easily come off.
