Abstract
The utility model discloses a kind of handrail joint design, it comprises poly-urethane rubber layer, polyester overlap joint layer of cloth, adhesion of surface skin layer, and polyester overlap joint layer of cloth is between poly-urethane rubber layer and adhesion of surface skin layer, and adhesion of surface skin layer is positioned at outermost; Being shaped as of polyester overlap joint layer of cloth is trapezoidal, and the upper length of polyester overlap joint layer of cloth is 70mm, and lower length is 129.6mm, and right-hand member height degree is 18mm, and right-hand member height is 43mm.The utility model has disperseed the stress of joint to concentrate, and has strengthened the bond strength of polyester overlap joint cloth.
Description
Technical field
The utility model relates to a kind of armrest system, particularly relates to a kind of handrail joint design.
Background technology
In recent years, along with the fast development of China's economic, GDP per capita constantly soaring, domestic subway, high ferro, large supermarket, Business Building and commercial center extend fast, for elevator and handrail industry development bring opportunity.
Adopt TPU(TPUE rubber) poly-urethane rubber handrail technology in domestic and first place in the world, its polyurethane material at high temperature has that viscosity is low, good fluidity, be applicable to extrude feature easy to process etc., and coupling of materials is simple, technological process is simplified, equipment investment is lower, material environment friendly can repeat to recycle etc. feature, for China and world's elevator handrail industry have been opened up a brand-new approach.
But TPU polyurethane handrail does when splicing annular at joint, because various material heat fusions have the existence of interface and joint, easily produce stress concentration phenomenon in joint, stress is concentrated and is prevalent in joint, wedge angle, hole, breach etc. and locates and neighborhood.Stress is concentrated and can be caused hard brittle material fracture, makes object produce endurance crack, relevant with the factor such as geometric configuration and loading regime of object.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of handrail joint design, and it has disperseed the stress of joint to concentrate, and has strengthened the bond strength of polyester overlap joint cloth.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of handrail joint design, it is characterized in that, it comprises poly-urethane rubber layer, polyester overlap joint layer of cloth, adhesion of surface skin layer, polyester overlap joint layer of cloth is between poly-urethane rubber layer and adhesion of surface skin layer, and adhesion of surface skin layer is positioned at outermost; Being shaped as of polyester overlap joint layer of cloth is trapezoidal, and the upper length of polyester overlap joint layer of cloth is 70mm, and lower length is 129.6mm, and right-hand member height degree is 18mm, and right-hand member height is 43mm.
Preferably, the cross sectional shape of described poly-urethane rubber layer is bending.
Positive progressive effect of the present utility model is: the utility model handrail joint design improves the inner and outside stress at joint polyester overlap joint cloth place of handrail and concentrates, better dispersive stress is concentrated, and has improved the bond strength of polyurethane handrail joint.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model handrail joint design.
Fig. 2 is the structural representation of polyester overlap joint layer of cloth in the utility model.
Detailed description of the invention
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model handrail joint design comprises poly-urethane rubber layer 1, polyester overlap joint layer of cloth 2, adhesion of surface skin layer 3, and polyester overlap joint layer of cloth 2 is between poly-urethane rubber layer 1 and adhesion of surface skin layer 3, and adhesion of surface skin layer 3 is positioned at outermost, as shown in Figure 2, being shaped as of polyester overlap joint layer of cloth 2 is trapezoidal, the upper length L1 of polyester overlap joint layer of cloth 2 is 70mm, lower length L2 is 129.6mm, right-hand member height degree H1 is 18mm, the high H2 of right-hand member is 43mm, the stress of the polyester overlap joint layer of cloth after improvement bears wide cut than improving a lot before, stress receiving area increases, stress is concentrated and is effectively disperseed, by the analysis and modification to dynamic fatigue test generation crack, the stress that the width of widening bonded areas brings when improving bending is concentrated, carry out after the test of same dynamic fatigue mailing Shanghai Mitsubishi to, structure after the utility model improves has not only been disperseed the concentrated destruction of inside and outside stress, also disperseed the stress that scantling and operate miss are brought to concentrate, thereby improve safety factor in flexural fatigue test, pass through smoothly test.The cross sectional shape of poly-urethane rubber layer 1 is bending, improves and bears pressure like this.
Above-described specific embodiment; technical matters, technical scheme and beneficial effect to solution of the present utility model further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
