Abstract
The invention relates to a projective jacket for a tenon of elevator guide rails. The projective jacket comprises a projective jacket head, a projective jacket neck and a projective jacket shoulder, wherein the projective jacket for the tenon of the elevator guide rails is formed by injection molding of plastic at one step; the wall thickness of the projective jacket is 1.5mm; a square cavity is formed in the projective jacket head, so that the guide rails are placed into the projective jacket head more easily; the projective jacket neck is arranged at the middle part of the projective jacket, is a narrow cavity which is inwards symmetrically recessed and is used for grabbing the guide rails, so that the guide rails are not easy to separate; the projective jacket shoulder positioned below the projective jacket neck is characterized in that an upper oblique-downward plane and a bottom plane form a cavity; two ends of the projective jacket shoulder are open, so that the projective jacket shoulder is suitable for the guide rails with different widths and the guide rails are enabled to be clamped into more easily; a connected part of the projective jacket shoulder and the projective jacket neck is formed by a greater R arc shape, so that the strength is improved, and the breakage caused by stress concentration is avoided. The projective jacket disclosed by the invention is reasonable in structural design, simple and practical; the projective jacket is made of plastic with good plasticity and toughness, so that the guide rails can be better protected; the projective jacket is low cost, is easy for processing, can be repeatedly used and is not easy to break, so that the service life is prolonged; materials are environment-friendly and can be recycled.
Description
Technical field
The invention belongs to elevator technology field, especially a kind of cage guide tenon sheath.
Background technology
At present; cage guide is all use sheet material cold drawing molding, and the steadily normal influence on system operation of its accuracy of form and position to elevator is very large, and its transport and the process medial end portions of putting the weakest; easily collide with and cause distortion; common sheath material is hard, easily breaks, does not often have good protective effect; and easily come off; closed at both ends, is not easy to snap in guide rail, can not adapt to the change in size of guide rail.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, stable performance and the cage guide tenon sheath of long service life.
The present invention solves its technical matters and takes following technical scheme to realize:
A kind of cage guide tenon sheath, comprise sheath head, sheath neck, sheath is takeed on, this cage guide tenon sheath is by plastic warp injection moulding once-forming, wall thickness 1.5mm, guard head forms square cavity above, guide rail can be made more easily to put into, middle part is provided with the narrow cavity that sheath neck is inwardly symmetrical depression, nip guide rail to be not easy to depart from, sheath shoulder forms cavity by the plane under being tilted to and base plane above below, both ends open, be applicable to the guide rail of different in width, more easily snap in, sheath shoulder has larger R arc to form with sheath neck junction, add intensity, the concentrated of stress is avoided to cause fracture.
Advantage of the present invention and good effect are:
Reasonable in design of the present invention, simple and practical, adopt the plastics of plasticity and good toughness, can better guide rail be protected, and the low easy machine-shaping of cost, can Reusability, not easy fracture, extend service life, material environment friendly reusable edible.
Accompanying drawing explanation
Figure l is constructional drawing of the present invention.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
The present invention relates to a kind of cage guide tenon sheath, comprise sheath head 1, sheath neck 2, sheath shoulder 3, this cage guide tenon sheath is by plastic warp injection moulding once-forming, wall thickness 1.5mm, guard head forms square cavity above, guide rail can be made more easily to put into, middle part is provided with sheath neck 2, it is the narrow cavity of inwardly symmetrical depression, nip guide rail to be not easy to depart from, sheath shoulder 3 forms cavity by the plane under being tilted to and base plane above, both ends open, be applicable to the guide rail of different in width, it is made more easily to snap in, sheath shoulder 3 has larger R arc to form with sheath neck 2 junction, add intensity, the concentrated of stress is avoided to cause fracture, reasonable in design of the present invention, simple and practical, adopt the plastics of plasticity and good toughness more can protect guide rail and the low easy machine-shaping of cost, can Reusability, not easy fracture, extend service life, material environment friendly reusable edible.
