Abstract
The utility model relates to a safety touch panel lift cable and aims at providing a lift cable which has the advantages of being good in bending performance, high in strength of extension, and long in service life. The safety touch panel lift cable comprises an outer protecting sleeve, a plurality of core wires arranged in the outer protecting sleeve and a pull bearing component and is characterized in that the pull bearing component is a cotton bundle which spreads along the length direction of the cable. The plurality of core wires are wound around in spiral shape and wrapped on the outer peripheral surface of the cotton bundle to form a winding layer with thickness equal to the diameters of the core wires. The axis of the strong cotton bundle coincides with the axis of the outer protecting sleeve. The core wires are conductors which are provided with insulating sheaths in wrapping mode and are one or a plurality of metal wires used for conducting of electric currents or electric signals. The outer protecting sleeve and the insulating sheaths are made of super-soft polyvinyl chloride (PVC).
Description
Technical field
The utility model relates to a kind of cable, especially matching used cable on the elevator.
Background technology
Cable is the basic accessory of lift facility; Many parts on the elevator such as elevator door often are in the state of frequent switch, and the cable of supporting elevator door-motor need bear the test of frequent bending; Conventional cable can not adapt to this kind situation, is easy to generate structural bending fatigue, influences the normal use of parts.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that above-mentioned background technology exists, and a kind of improvement of elevator cable is provided, and this elevator cable should have that flexural property is good, tensile strength is high and the characteristics of long service life.
The technical scheme that the utility model provides is: the safety edge elevator cable comprises oversheath, is arranged in several heart yearns and tensile member in the oversheath; It is characterized in that described tensile member is the cotton thread bundle, this cotton thread bundle stretches along the length direction of cable.
Said several heart yearn spiralitys are twined the external peripheral surface that is coated on the cotton thread bundle, form the winding layer that thickness equates with core line diameter.
The axis of said powerful cotton thread bundle and the dead in line of oversheath.
Said heart yearn is the conductor that is coating insulation sheath; This conductor is single or the many wires that are used for the conducting electric current or the signal of telecommunication.
Said oversheath is that special soft pvc is made.
Said insulation sheath is that special soft pvc is made.
The beneficial effect of the utility model is: after having adopted the cotton thread bundle, increased the tensile strength of cable, and cotton thread Shu Zuowei filler, not only guaranteed the rounding of cable, also increased the pliability of cable; Add that spirality twines the heart yearn of the external peripheral surface be coated on the cotton thread bundle, and with the insulation sheath and the oversheath of special soft pvc making; The softness of whole cable is superior, and flexural property is good, is particularly suitable for the supporting use of parts of frequent movement, and has the useful life longer than common cable.
Description of drawings
Fig. 1 is the cross-sectional structure sketch map of the utility model.
Fig. 2 is the left TV structure sketch map (analysing and observe part for only removing the view behind the oversheath) of Fig. 1.
Embodiment
Safety edge elevator cable shown in Figure 1 comprises oversheath 1, is arranged in several heart yearns 2 and tensile member 3 in the oversheath; This is the conventional structure of elevator cable.
The improvement of the utility model: the one, described tensile member is selected cotton thread bundle (preferred powerful cotton thread bundle) for use, and this cotton thread bundle stretches along the length direction of cable, can be used for increasing the tensile strength and the bending property of cable.The cotton thread bundle is that the many cotton threads that are arranged in parallel are formed, and directly outsourcing obtains.
The 2nd, said several heart yearn spiralitys are twined the external peripheral surface that is coated on the cotton thread bundle, form the winding layer that thickness equates with core line diameter; Make powerful cotton thread bundle be positioned at the central authorities of cable (its axis preferably and the dead in line of oversheath).
Said heart yearn is the conductor 2-1 that is coating insulation sheath 2-2; This conductor is single or the many wires (preferred copper wire or aluminium wire) that are used for the conducting electric current or the signal of telecommunication.
Said oversheath is that special soft pvc is made; Said insulation sheath is that special soft pvc is made; Special soft pvc buyable obtains.
