Description
Technical field
It the utility model is related to a kind of more nut type lifting towers of single screw.
Background technology
In the prior art, using leading screw pay carry out transmission lifting bar or tower be usually more leading screws, often section set 1 leading screw and
Some gear drives, complicated, limited space, and manufacture that cost is higher, in addition, the lifting tower of more screw structures is due to knot
Structure is relative complex, and also relative difficulty is repaired when breaking down.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of simple in structure, easy to maintenance, manufacture cost relatively
The more nut type lifting towers of single screw that are low and can be locked in any tower section position.
In order to solve the above technical problems, the more nut type lifting towers of the single screw of the utility model, there is a leading screw, multiple
The tower section of rectangular cross-section and drive the leading screw rotate transmission mechanism, the tower section by the coxopodite positioned at outside, positioned at interior
The epimerite of side and multiple inter-chamber tower sections composition between coxopodite and epimerite, the bottom of epimerite and inter-chamber tower section be respectively provided with
The matched nut of leading screw, the bottom of leading screw are loaded on the bottom of the coxopodite by bearing, and the leading screw includes top
Thread segment and the feed rod section of lower part, the nut of the epimerite bottom are located on the thread segment of leading screw feed rod section, inter-chamber tower section
The nut of bottom is located in the feed rod section of leading screw；Locking bolt, phase are housed on the upper column section wall of coxopodite and the inter-chamber tower section
The middle and lower part tower section wall of epimerite and the inter-chamber tower section is answered to be equipped with and the matched groove in locking bolt head.
As the improvement of the utility model, on the excircle of the nut of epimerite and inter-chamber tower section bottom installing formed with
Spline, correspondingly the bottom of epimerite and inter-chamber tower section offer the nut mounting hole with spline, the flower in nut mounting hole
Keyway is engaged with the spline on the nut excircle, and spring, nut are housed in the nut mounting hole of nut upper and lower
Spacing pressing plate is housed at the aperture of mounting hole bottom.
The more nut type lifting towers of single screw using the above structure, when rising tower starting, leading screw drives epimerite tower to rise, other
Tower section is static, when epimerite tower nut disengages leading screw in advance, manually can lock epimerite tower and adjacent inter-chamber tower section, be unified into one
Body, after tower of continuing rising, epimerite tower nut disengages leading screw, and adjacent towers section nut enters transmission, and the spring of nut upper and lower sides can ensure two
A nut will not interfere with each other in work transformation process, cause it is stuck, below it is a few section tower operation principles and sequence of movement with this
Analogize, complete the lifting of tower section.The present apparatus completely using can rigid self-locking common leading screw up-down mode, dexterously can only be complete
Leading screw into 1 stroke completes multiple-pass action, simple in structure, easy to operate, easy to repair.
