Existing anti-reverse mechanism has following shortcoming: one, preventing rotor is pyramidal structure, makes to only have in preventing rotor two points to contact with outer pillar, and preventing rotor is fragile, and cannot play anti-reverse effect after damage, service life is short.
Two, existing anti-reverse mechanism is made up of an anti-rotation block-material #45 steel and four preventing rotor-material copper H62, and preventing rotor resistance to abrasion is relatively poor, and cost is high.
Three, preventing rotor and outer pillar interference fit, need knock in hammer during installation, preventing rotor is yielding, then inconvenience when dismantling.
Utility model content
The utility model provides following technical scheme: the novel anti-reverse mechanism of elevator leading screw, comprise interior anti-rotation assembly and rectangle pillar, described interior anti-rotation assembly is made up of anti-rotation block, Anti-rotary block cover plate and preventing rotor, described anti-rotation block entirety is in square, the corner of this anti-rotation block is equipped with preventing rotor, this preventing rotor entirety is cylindrical, the top of anti-rotation block is provided with an Anti-rotary block cover plate, this Anti-rotary block cover plate is fixedly connected with anti-rotation block by screw, and Anti-rotary block cover plate coordinates with anti-rotation block and compressed by preventing rotor; The center of described anti-rotation block is provided with through hole, and the side of this anti-rotation block is provided with the screw coordinated with ball nut; This interior anti-rotation assembly is located in rectangle pillar; The material of described preventing rotor is polytetrafluoroethylene.
As further scheme of the present utility model: install ball nut in described through hole, this ball nut is fixedly connected with anti-rotation block by screw.
As further scheme of the present utility model: the inwall corner of described rectangle pillar is provided with the cylinder shape groove coordinated with preventing rotor.
As further scheme of the present utility model: the material of described anti-rotation block and Anti-rotary block top board is Q235.
Compared with prior art, the beneficial effects of the utility model are: the novel anti-reverse mechanism of this elevator leading screw has the following advantages: one, the utility model changes the shape of preventing rotor, area of contact between columniform preventing rotor and rectangle pillar is larger, single preventing rotor bus area of contact increases 18 times, and a whole set of contact surface increases 144 times; Two, the material of preventing rotor changes polytetrafluoroethylene into by copper H62, and resistance to abrasion improves, and considerably increases service life; Three, preventing rotor is compressed by anti-rotation block and Anti-rotary block cover plate, tighter with nut, and assembling is simple and to preventing rotor zero damage, and demolition and maintenance are convenient.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-9, in the utility model embodiment, the novel anti-reverse mechanism of elevator leading screw, comprise interior anti-rotation assembly and rectangle pillar 4, described interior anti-rotation assembly is made up of anti-rotation block 1, Anti-rotary block cover plate 2 and preventing rotor 3, described anti-rotation block 1 entirety is in square, the corner of this anti-rotation block 1 is equipped with preventing rotor 3, this preventing rotor 3 is overall cylindrical, the top of anti-rotation block 1 is provided with an Anti-rotary block cover plate 2, this Anti-rotary block cover plate 2 is fixedly connected with anti-rotation block 1 by screw, and Anti-rotary block cover plate 2 coordinates with anti-rotation block 1 and compressed by preventing rotor 3; The center of described anti-rotation block 1 is provided with through hole 101, and install ball nut in through hole 101, this ball nut is fixedly connected with anti-rotation block 1 by screw, and the side of this anti-rotation block 1 is provided with the screw 102 coordinated with ball nut; This interior anti-rotation assembly is located in rectangle pillar 4, the inwall corner of this rectangle pillar 4 is provided with the cylinder shape groove coordinated with preventing rotor 3, area of contact between preventing rotor 3 and cylinder shape groove greatly increases relative to existing taper preventing rotor, effectively reduces wearing and tearing; The material of described anti-rotation block 1 and Anti-rotary block top board is Q235, and the material of preventing rotor 3 is polytetrafluoroethylene, and preventing rotor 3 material softer, resistance to abrasion is better than copper, and cost is low.
