Technical field
The utility model relates to plastic-blasting part assembling field, especially, relates to a kind of stick harness.
Background technology
Plastic-blasting spare needs to be fastenedly connected through screw with other parts when general assembly is assembled, and indivedual screw holes need play the ground connection effect, so a lot of screw holes are arranged on the plastic-blasting spare.The thread surface of these screw holes also can form coating in the plastic-blasting process, cause follow-up stripped thread when playing screw, screw can't be squeezed into or phenomenon such as screw hole imperfect earth.
The utility model content
The utility model purpose is to provide a kind of stick harness, in the plastic-blasting process, forms coating to solve screw hole, causes screw to assemble technical problem bad and screw hole imperfect earth.
For realizing above-mentioned purpose, the utility model provides a kind of stick harness, comprises chock plug, has the guiding end; The plug tail is connected with chock plug, and and chock plug between form the screw hole auxiliary section.
Further, chock plug is a taper type.
Further, the axis direction of chock plug is provided with endoporus.
Further, endoporus extends to the inside of plug tail.
Further, the screw hole auxiliary section is the ring-shaped depression structure.
Further, the taper type base diameter is less than the diameter of plug tail, and the taper type base diameter is greater than the diameter of ring-shaped depression structure.
Further, chock plug is one-body molded with the plug tail.
Further, chock plug is a silica gel with the material of plug tail.
Further, the shore hardness of silica gel is m, 45 degree≤m≤55 degree.
Further, chock plug is coated with coloured coating with plug tail outer surface.
The utlity model has following beneficial effect:
The size of plug tail adapts with corresponding screw hole, and chock plug is conveniently taken, and has protected well that screw hole is not influenced by coating in the plastic-blasting process, has improved follow-up assembling, has improved the security performance of complete machine.
Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the sketch map according to the stick harness of the utility model; And
Fig. 2 is the cross-sectional schematic according to the stick harness of the utility model.
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1 and Fig. 2, the stick harness according to the utility model comprises: chock plug 20 has the guiding end; Plug tail 10 is connected with chock plug 20, and and chock plug 20 between form the screw hole auxiliary section.The size of plug tail 10 adapts with corresponding screw hole, and chock plug 20 is conveniently taken, and has protected well that screw hole is not influenced by coating in the plastic-blasting process, has improved follow-up assembling, has improved the security performance of complete machine.
Referring to Fig. 1, chock plug 20 is a taper type.The platform bottom of the taper type of chock plug 20 is connected with plug tail 10, conveniently takes.
Referring to Fig. 2, the axis direction of chock plug 20 is provided with endoporus 11.Endoporus 11 extends to the inside of plug tail 10.Endoporus 11 can strengthen the elasticity of whole stick harness, also saves material simultaneously.
Referring to Fig. 1 and Fig. 2, the screw hole auxiliary section is the ring-shaped depression structure.The taper type base diameter is less than the diameter of plug tail 10, and the taper type base diameter is greater than the diameter of ring-shaped depression structure.It is hand-held that the ring-shaped depression structure is convenient to chock plug 20, and when stick harness was pulled out from screw hole, the ring-shaped depression structure was convenient to stressed extracting.
Referring to Fig. 1, chock plug 20 is one-body molded with plug tail 10.Stick harness is the one piece injection mo(u)lding.
Chock plug 20 is a silica gel with plug tail 10.The shore hardness of silica gel is m, 45 degree≤m≤55 degree.Why adopt the silica gel material to be because the silica gel goods have good temperature resistance, can use repeatedly under the hot conditions of the curing oven of spray molding production line and drying oven.And the elasticity of silica gel is better and material price is cheap; In order to reach the purpose in stick harness sealing screw hole, the shore hardness of silica gel is 45 degree≤m≤55 degree simultaneously.
Chock plug 20 is coated with coloured coating with plug tail 10 outer surfaces.Stick harness is divided into 3 kinds of different sizes, a kind of all apertures that are applicable to diameter 3.3 to 4mm, and external surface coating is blue; A kind of all apertures that are applicable to diameter 4.5 to 6mm, outer finishing coat are red; A kind of all apertures that are applicable to diameter 7.8 to 10mm, external surface coating are white; Three specifications are applicable to the protection of present all different big or small screw holes of plastic-blasting spare basically, distinguish through different colours, reduce the difficulty of artificial identification, have increased the versatility of stick harness.
The stick harness structural design has adopted interference fit, so in operation, need rotate and fill in the screw hole, can guarantee so just that stick harness can not come off easily in the protection process to make the protection failure.
The powder coating that stick harness surface in the protection process can form plastic-blasting can adopt stripping machine to remove the powder coating of the plastic-blasting on stick harness surface, uses repeatedly.
This stick harness is applicable to the protection of plastic-blasting spare screw hole, flange hole and through hole, also be applicable to simultaneously spray paint, the protection of screw hole, flange hole and the through hole of electrophoresis.
From above description, can find out that the utility model the above embodiments have realized following technique effect:
The size of plug tail adapts with corresponding screw hole, and chock plug is conveniently taken, and has protected well that screw hole is not influenced by coating in the plastic-blasting process, has improved follow-up assembling, has improved the security performance of complete machine; Simple in structure, easy to process, highly versatile has improved production efficiency.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
