The anticreep elevator center opening door head device of anticreep reliability between plate.
This utility model solves its technical problem and is achieved through the following technical solutions：
A kind of anticreep elevator center opening door head device, including base plate and two link plates, make along its length on base plate and lead
Rail, is mounted on guide wheel on link plate, the guide wheel is oriented to and runs on edge on the guide rail of base plate, it is characterised in that：Institute on the base plate
Upper guide groove and lower guide channel are formed between the guide rail and base plate of system, be formed with the link plate the upper mousing-hook that is installed in upper guide groove and
The lower mousing-hook being installed in lower guide channel.
And, described guide rail Jing bendings form circular arc upper rail face and circular arc lower guideway face；Described upper guide groove
For the circular arc upper guide groove that bending is formed, lower guide channel is the circular arc lower guide channel that bending is formed.
And, described upper mousing-hook, lower mousing-hook are on link plate bending after locally punching and are formed, upper mousing-hook from
The inside bending of plate face of link plate is simultaneously formed with downward coupler body, and lower mousing-hook is from the inside bending of plate face of link plate and is formed with hook upwards
Body.
And, described upper mousing-hook is two, and described lower mousing-hook is corresponding to two upper mousing-hook centre positions
One.
And, described link plate bottom fold is formed with door-plate and installs bottom edge, installs bottom in the door-plate and bending shape is punched on
Into installing plate, on the installing plate installing hole is formed with.
Advantage of the present utility model and have the beneficial effect that：
1st, this anticreep elevator center opening door head device, made guide rail is that bending is formed on its base plate, and guide rail and bottom
Upper guide groove and lower guide channel are defined between plate, hook and lower draw-bar, upper hook and lower draw-bar difference clamp are made on link plate
In upper guide groove and lower guide channel, so as to the anticreep performance between link plate and base plate can be effectively improved, it is ensured that prevent the head device from meeting
To in the case of high temperature deformation, it may have good anticreep effect.
2nd, this anticreep elevator center opening door head device, guide rail is that Jing bendings form circular arc upper rail face and circular arc lower guideway
Face；The circular arc upper guide groove that described upper guide groove is also formed for bending, lower guide channel is the circular arc lower guide channel that bending is formed, its tool
Have the advantages that easy to process, it is to avoid original bending technique difficulty is big, and form asking for sheet material stress concentration caused behind right angle
Topic.
3rd, this anticreep elevator center opening door head device, upper mousing-hook, lower mousing-hook are on link plate bending after locally punching
Formed, upper mousing-hook is from the inside bending of plate face of link plate and is formed with downward coupler body, lower mousing-hook is from the plate face of link plate to infolding
Curved and be formed with coupler body upwards, simple with processing technique, without the need for the processing such as welding, advantage high in machining efficiency can be the bottom of with
The guide groove clamp of plate ensures anticreep effect.
4th, this anticreep elevator center opening door head device, link plate bottom fold is formed with door-plate and installs bottom edge, and in the door-plate bottom is installed
Installing plate is formed along the bending of upper punching, installing hole is formed with the installing plate, processing technique is simple, it is easy to be fixed with door-plate
Install.
5th, this utility model scientific structure design rationally, is hooked anti-using the top between link plate and floor rail and lower step
De-, with stabilized structure, reliability is high, the advantage of good anti-drop effect, is divided in a kind of anticreep elevator with higher innovation
