Abstract
The invention relates to a clamping insertion strip with a compound skeleton, which comprises an insertion strip main body made of a hard modified PVC material. The insertion strip main body is an S-shaped structure, and one layer of clamping body made of a soft modified PVC material is compounded on the external surface of the starting straight section of the S-shaped insertion strip main body. The clamping body is provided with a clamping strip convex body for clamping a clamping body assembly in a stretching way in the extension direction of the starting straight section, and an enhancing skeleton is embedded between the clamping body and the compounding surface of the starting straight section of the insertion strip main body or in the starting straight section. The insertion strip main body, the enhancing skeleton and the clamping body are integrally compounded extrusion parts. The steel enhancing skeleton has high strength, small influence by temperature difference, small contraction distortion and strong impact resistance, and the expansion and contraction of the clamping insertion strip is reduced. The stainless steel insertion strip not only can be wrapped but also can be exposed and is beautiful in appearance. The clamping insertion strip provided by the invention has the advantages of small contraction distortion, strong impact resistance, small contraction gap in clamping insertion strip joint, good weather resistance, beautiful appearance and long service life and is an ideal substitute for the prior art.
Description
Technical field
The present invention relates to the escalator technical field, particularly be applied to clamp the clamping filler rod of escalator inside and outside cover board and glass, specifically, is a kind of clamping filler rod and moulding process thereof with compound skeleton.
Background technique
Elevator, staircase market competition are fierce day by day at present, and product is brought in constant renewal in.Each big elevator company simplifies at the prerequisite next part of ensuring the quality of products approximately, and the Stamping Steel Ribbon that staircase is used is constantly replaced improvement, and the Stamping Steel Ribbon that staircase is used plays clamping, sealing, decorating action nothing but in view of its function.Though the Stamping Steel Ribbon that original staircase is used can play clamping, sealing, decorating action; But owing to be the goods of pure plastics; Can't overcome because the length difference that expands with heat and contract with cold and exist; Particularly outdoor because the temperature difference is big, the joint of product can make the slit, joint become big with the passing of variation of temperature and time, and compound skeleton clamping filler rod has solved this problem just.
Summary of the invention
Technical problem to be solved by this invention is the present situation to existing technology, provides a kind of contraction deformation little, and anti-impact force is strong, and good weatherability is specious, the clamping filler rod and the moulding process thereof with compound skeleton of long service life.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of clamping filler rod with compound skeleton; The filler rod body that comprises hard modified PVC material; Wherein, The initial straightway outer surface of filler rod body is compounded with the clamping body of the soft modified PVC material of one deck; Clamping body extends along the bearing of trend of initial straightway and is shaped on the clamp bar convex body that is used to clamp the cramping body assembly, between the composite surface of clamping body and the initial straightway of filler rod body or be embedded with the enhancing skeleton in the initial straightway, said filler rod body, strengthens skeleton and clamping body is that part is extruded in a bluk recombination.
The terminal straightway inner side surface of above-mentioned filler rod body is shaped on the cramping body assembly and fastens the step-like barb stage body that clamps.
Above-mentioned enhancing skeleton is the stainless steel sheets or the cold rolling steel disc of roll forming.
Above-mentioned cramping body assembly comprises clamping body and the clamping buckling member equipped with the clamping body-fixed; The clamping body is connected through interference fit with the clamping buckling member, and the fastening boss that the clamping buckling member is shaped on closely fastens setting-in mutually with the barb stage body.
The above-mentioned S-shaped structure of filler rod body perhaps is the shape of setting-in cooperation each other.
Above-mentioned a kind of moulding process with clamping filler rod of compound skeleton may further comprise the steps:
The percentage that Corvic in the above-mentioned step 1 accounts for is 60% to 85%, and plasticizing agent is 0% to 30%, and auxiliary material is 5% to 15%.
Compared with prior art; A kind of clamping filler rod of the present invention with compound skeleton; The filler rod body that comprises hard modified PVC material; Wherein, the initial straightway outer surface of filler rod body is compounded with the clamping body of the soft modified PVC material of one deck, and clamping body is shaped on the clamp bar convex body that is used to clamp the cramping body assembly along the bearing of trend extension of initial straightway; Be embedded with the enhancing skeleton between the composite surface of clamping body and the initial straightway of filler rod body or in the initial straightway, filler rod body, enhancing skeleton and clamping body are that part is extruded in a bluk recombination.Clamping filler rod of the present invention by the filler rod body, strengthen skeleton and clamping body one bluk recombination and extrude and form, strengthen between the composite surface that skeleton can be embedded in clamping body and initial straightway or in the initial straightway, strengthening the passable material of skeleton is the stainless steel sheets or the cold rolling steel disc of roll forming; Intensity is high; Receive temperature difference influence little, contraction deformation is little, and anti-impact force is strong; Be used in combination effective weather resistance that has improved whole clamping filler rod with clamping the filler rod miscellaneous part, improved clamping filler rod working life.The present invention plays escalator inside and outside cover board and glass and clamps decorating action, in be lined with stainless steel sheets, reduce to clamp filler rod harmomegathus, stainless steel sheets can wrap in the inside, can be exposed again, and very attractive in appearance.Owing to reduced clamping filler rod harmomegathus, the present invention has also solved original inside and outside cover board and has clamped the problem that the filler rod joint must be provided with contraction joint, and particularly outdoor, the temperature difference differs tangible zone.It is little that invention has a contraction deformation, and anti-impact force is strong, good weatherability, and the advantage of specious, long service life is the ideal substitute of existing technology.
