Abstract

The invention discloses an automatic brake telescopic supporting column, which structurally comprises a plurality of mutually sleeved tubular supporting columns. The surfaces of the supporting columns are formed with equidistant through holes, a helical spring and a pressing handle are fixed, in a penetrative and inserting manner, in two lugs of the telescopic supporting column by using a pin column so that the helical spring maintains the end of the pressing handle bounced, a cylinder at the other end is inserted into the through holes on the telescopic supporting column, and the end face of the brake column body is slope-shaped. When the supporting column is pulled out for being used, every through hole arranged on the supporting columns can slide over the slope smoothly owing to the slope-shaped end face of the cylinder arranged in the holes of the supporting columns, however, reversal pushing is not allowed, and if one supporting column needs to be pushed into another supporting column, pressing downwards the pressing handle on the brake device by one hand is indispensable so that the cylinder moves out of the round through holes to lose the effect of reversal brake; the size of the automatic brake telescopic supporting column can be determined as required to expand the applicable scope, can be used for the lifting device in multiple fields, and has the characteristics of being convenient and safe in operation, simple in manufacturing, easy in maintenance and the like.

Description

The Braking mode telescopic prop

Technical field

The present invention relates to a kind of telescopic prop, especially have the telescopic prop of Braking mode.

Background technology

Brake setting on the telescopic prop in using in a lot of fields at present, there are many drawbacks, such as four telescopic props using on the lifting tent, on the outer square tube pillar a plurality of circular holes are arranged, the check mechanism of adjusting the tent height is arranged on nexine square tube pillar cavity inside, eject a cylinder button with spring in it, when closing, use must it be pressed into inside with finger, telescopic prop just can be drawn out or push, moreover this structure is only limited to two joint pillars, can't expand joint number and increase height, operational hazards is hard, in case drawbacks such as damage inconvenient maintenance.

Summary of the invention

In order to overcome the drawback that prior art in use exists, it is flexible to the invention provides a kind of use handling safety, the more piece Braking mode telescopic props that can be used on various need adjusting device height of simple structure easy-maintaining.

The technical scheme that technical problem adopted that the present invention solves is: Braking mode telescopic prop, its structure comprise telescopic prop and place self-braking device on the telescopic prop.

Described first segment pillar top is equipped with a hinge hole, every pitch circle tubbing one side is made the plane, making telescopic prop be meshing with each other cover can only push-and-pull after inserting, non-rotatable, on the plane of second pillar and the 3rd pillar, open-work is set equidistantly, a check mechanism that can go deep into automatically in its open-work is respectively put in first pillar and the second pillar lower end, check mechanism likeness in form device half of clip thereon, just the other end at handle is provided with a braking cylinder that gos deep into automatically in the open-work, with a pin helical spring is fixed in two journal stirrups of telescopic prop together with pressure handle is interspersed, make helical spring keep the pressure handle end is upspring, other holds cylinder to insert in the open-work on the telescopic prop, and described braking cylinder end face is a ramped shaped.

Described to place the braking cylinder of check mechanism on the Braking mode telescopic prop be cylindrical body, also can be the square tube body, and brake hole placed on it is a circular hole, also can be square hole.

Described Braking mode telescopic prop not only can be applicable on the lifting tent, because of its size, and length, joint number can be decided arbitrarily according to demand, can be extended to the more areas of other lifting gear for this reason.

Braking mode telescopic prop of the present invention in sum, when pulling out when using because of placing the cylindrical end face in the pillar hole to be ramped shaped, place each open-work on the pillar all can slip over from the inclined-plane smoothly, but irreversible to pushing, save in addition in the pillar if this joint pillar will be sent into, just must will press under the pressure handle on the check mechanism with a hand, cylinder is come out in the circle open-work, make it lose reverse braking action and get final product, have easy and safe to operate, make simply characteristics such as easy-maintaining.
