Description

Interlock between the pipe of a kind of single screw Mechanical lifter

Technical field

This Invention relates to the building block of a kind of single screw telescopic Mechanical lifter of many pipes, interlock between the pipe of the many pipes of a kind of single screw telescopic Mechanical lifter.

Background technology

There is the Mechanical lifter of certain weight lifting ability for fast erecting antenna or lighting etc. aloft.

In prior art, disclosing a kind of single screw telescopic Mechanical lifter of many pipes in Chinese patent ZL 98 2 38478.5, this Mechanical lifter has interlock between body, lifting drive and pipe.

Body is the many pipes that axis diameter on the same line is nested together from big to small, in many pipes, a piece pipe of outermost is end pipe, a pipe in is push pipe, remaining pipe is inner tube, end pipe is fixed on base, gap between adjacent pipe is identical, the outer wall of push pipe and inner tube has feather key vertically, there is annular upper baffle ring the upper end of end pipe and inner tube, the internal diameter of upper baffle ring matches with the external diameter of adjacent inboard pipe, there is filler ring under the annular matched with upper baffle ring the lower end of push pipe and inner tube, the external diameter of lower filler ring closes with the diameter compatible of adjacent outer pipe, the inner periphery of upper baffle ring has the gathering sill that the feather key with adjacent circular tube external wall matches.Body is arranged on base, and base has the lifting drive of body.Interlock between pipe is had between the adjacent pipe of body.

Being lifted up the push pipe of body, because of end pipe and the upper end of the inner tube lower filler ring matched that has the lower end of annular upper baffle ring, push pipe and inner tube to have with upper baffle ring, many pipes can be allowed to stretch out successively becomes stock, and now Mechanical lifter height is maximum, is the state risen.When falling, push pipe and inner tube fall in end pipe, and now Mechanical lifter height is minimum, are the states of landing.

The lifting drive of body can rise or land many pipes successively.

Between pipe, interlock can connect together adjacent inner side pipe at adjacent inner side pipe after outside pipe rises with outside pipe.

The lever of lower section in interlock has the pipe being hinged on inner tube and push pipe between the pipe of the many pipes of above-mentioned single screw telescopic Mechanical lifter, one end of lever have can straight circular bar shape radial peg outside the through hole protruded tube from tube wall, the other end of lever has the spring making radial peg be subject to extend radially out pipe external force.The pin-and-hole coordinated with above-mentioned radial peg is had with above the tube wall of above-mentioned inner tube adjacent outer pipe.

During use, after inner tube or push pipe rise, the radial peg below pipe can be stretched out from the through hole of this pipe because of the elastic force of spring and insert in the pin-and-hole above adjacent outer tube wall, and pipe is connected together with adjacent outer pipe.

Between the pipe of this Mechanical lifter, interlock has a following deficiency:

1. between pipe, the connector of interlock is straight circular bar shape radial peg and the circular pin hole of adjacent outer pipe being hinged in inner tube lever one end, lower section, and radial peg is to insert pin-and-hole by elasticity, make adjacent pipe radially connected process and chain after be not the most reliable；

2. attachment means between the radial tubes that between pipe, interlock is only connected for lifting, attachment means not after Mechanical lifter declines, between the tube axial of adjacent pipe, when Mechanical lifter rises again, adjacent pipe can be fitted because gap is less contact, this laminating contact causes adjacent pipe to rise because of frictional force in the case of untrue being connected sometimes simultaneously, because being connected the most really, after contact laminating disappears, the pipe simultaneously risen because of frictional force can fall suddenly, and the collision produced of falling suddenly can damage Mechanical lifter.

Have between lock shaft and lock tube and make lock shaft be subject to allow the torsion spring of notch rotatory force downwards of square groove.

The interior circular hole upper end hole mouth of lock has upper baffle ring.

Having the cross section matched with above-mentioned lock on the outer circumference surface of bottom plate is half strip circle locked groove.

During installation, this The lock of invention is arranged on end pipe and the upper end of inner tube of single screw Mechanical lifter, and above end pipe and inner tube, the arranged on left and right sides of tube wall need to have and this respectively The pin-and-hole that communicates of lock tube lockhole of invention, after lock is arranged on the upper end of end pipe and inner tube, lock can through lock tube lockhole and pin-and-hole laterally out of, bottom plate is arranged on the arranged on left and right sides of outer tube wall below push pipe and inner tube.

Single screw Mechanical lifter is when the state of landing, on end pipe and inner tube originally The latch hook of invention lock is to insert on adjacent inboard pipe in the hook lock of lock, and is hooked in the square groove that on adjacent inboard pipe, outside the lock shaft of lock, notch is square obliquely, makes adjacent pipe realize axial being sequentially connected with.

When rising single screw Mechanical lifter, it is with the lifting drive of body, push pipe and inner tube to be risen successively.nullDetailed process is，Push pipe and an inner tube rise，Its bottom plate upper surface is against the upper baffle ring lower surface of lock on adjacent outer pipe，Pipe outside this is lifted up，The latch hook being hooked in square groove is hooked to oblique lower section the square groove notch on lock shaft，Lock shaft is i.e. allowed to rotate a dynamic angle to a direction，Spacer pin in lock tube and the stopper slot on lock shaft，Limit lock shaft to rotate in this angle，Owing to lock shaft rotates an angle to a direction，The square groove of notch side obliquely outside lock shaft is made to forward the oblique lower section of notch to，The notch simultaneously making the dihedral angle shape lock groove of in lock shaft inside circumference 90 degree is rotated up，Lock groove is released lock in lock groove，Lock is through lock tube lockhole、On pin-and-hole entrance bottom plate outer circumference surface in locked groove，With lock shaft lock tight against in locked groove，Adjacent pipe is made to realize radially connected，Push pipe and inner tube is allowed to be maintained at the state of rise.

During the landing of single screw Mechanical lifter, latch hook inserts on adjacent inboard pipe this In the hook lock of invention and enter in the square groove of the oblique lower section of notch, stir another direction of lock shaft rotation direction and rotate an angle, make lock can return to, in lock groove, release the radially connected of adjacent pipe from locked groove.

This Invention has between tube axial interlock between interlock and radial tubes, between tube axial, interlock can be after Mechanical lifter declines, adjacent pipe is allowed axially to couple together, when Mechanical lifter rises again, adjacent pipe will not fit because gap is less contact frictional force and rise simultaneously, it is to avoid the pipe simultaneously risen suddenly fall produce collision and damage；The stiff member that between radial tubes, interlock is made up of lock shaft and lock, is the connection of stiff member after adjacent pipe is radially connected, make adjacent pipe radially connected process and chain after the most reliable.
