Abstract

The invention provides a bicycle lead casing. The bicycle lead casing comprises an internal tube, a fibrous layer and an external covering layer, the internal tube is used for the pass-through of a bicycle lead, the fibrous layer is formed by arranging a plurality of strands around the internal tube and winding around the internal tube, the plurality of stands are prepared by using glass fibers, a plurality of recessed joints positioned among the plurality of strands are formed on the external surface of the fibrous layer, the external surface of the fibrous layer is covered with the external layer, and the recessed joints are filled up by parts of the external covering layer. By adopting the above technical scheme, the bicycle lead casing has a good bend toughness and a good durability.

Description

Automobile-used wire socket

Technical field

The invention relates to a kind of automobile-used wire socket.

Background technique

In general, the braking system of bicycle or speed variator system are for user, to control near a brake wire or shift cable are connected to handgrip, and user's strength can be passed to braking system or speed variator system via brake wire or shift cable, to press from both sides the actions such as evil spirit.

Therefore, as the bicycle lead of brake wire or shift cable etc. is real, be indispensable, for example, and bicycle lead must be connected to start region (brake mechanism) from handgrip, in way, must extend a segment distance through vehicle frame, and, in order to coordinate vehicle frame, bicycle lead is moderately crooked setting often, yet, pass through the crooked bicycle lead more difficult strength of transmitting exactly when pulled, even may block and fault, become and drive safe secret worry.

To this; industry develops a kind of sleeve pipe of bicycle lead; to wear in the inner for bicycle lead; and allow bicycle lead to move axially in the inner; structure whereby, the mobile route of bicycle lead just can be guaranteed and be located, and the situation such as can not only avoid bicycle lead to pull having some setbacks, block; more can, as the use of protection, avoid bicycle lead to be subject to external force collision, wearing and tearing or rainwater or the destruction of Exposure to Sunlight to bicycle lead.

In general, this sleeve pipe is to have comprised by metal bands to be wound around the internal layer forming and to be coated on the clad outside bands, wherein this clad is in order to provide good weatherability and structural strength, normal use polypropylene is its material, yet, firm but the bendable detorsion of metal bands structure, overbending may cause fracture, as sleeve pipe that must be crooked, still has deficiency.

Summary of the invention

Main purpose of the present invention, is to provide a kind of automobile-used wire socket, and preferably bending elasticity and durability degree can be provided.

For achieving the above object, the present invention is by the following technical solutions:

Plant automobile-used wire socket, it comprises;

One inner tube, this inner tube is in being arranged in for a bicycle lead;

One layer of fibers, is arranged and is wound around this inner tube and form around this inner tube by a plurality of strands, and respectively this strand is to make with glass fibre, and this fibrolaminar outer surface is formed with a plurality of recessed joints between those strands;

One outer covering layer, this outer covering layer is coated on a part for this layer of fibers outer surface and this outer covering layer and fills up this plurality of recessed joints.

In a preferred embodiment, described inner tube is made with polyethylene.

In a preferred embodiment, described inner tube is made with Furtulon.

In a preferred embodiment, described inner tube is made with plastic-steel.

In a preferred embodiment, described outer covering layer is to drench and be overlying on this layer of fibers outer surface cooling forming with the nylon material of hot melt.

Beneficial effect of the present invention is: automobile-used wire socket provided by the invention is because adopting fiberglass strand to be wound around, there is preferably bending elasticity, and adopt nylon material can have preferably binding ability with glass fibre as outer covering layer, make overall structure more firm, and further strengthen durability by high weathering resistance, high resistance impact force and the high burnish resistance of nylon.

Embodiment

Below only with embodiment, the enforcement aspect that the present invention is possible is described, however not in order to limit the category of institute of the present invention wish protection, first give chat bright.

Please refer to Fig. 1 to Fig. 3, the invention provides a kind of automobile-used wire socket 10, comprise an inner tube 11, a layer of fibers 12 and an outer covering layer 13.

This inner tube 11 has a cavity and in a bicycle lead 20 is arranged in, its material is preferably polyethylene, Furtulon or plastic-steel; This layer of fibers 12 is arranged and is wound around this inner tube 11 and form around this inner tube 11 by a plurality of strands 121, respectively this strand 121 is to make with glass fibre, the outer surface of this layer of fibers 12 is formed with a plurality of recessed joints between those strands 121, in more detail, in general, respectively this strand 121 is cylinder strip, therefore, even if these a plurality of strands 121 each other close proximity are wound around, its outer surface still can form the recessed joint of a plurality of ditch shapes; 13 of this outer covering layers are coated on a part for these layer of fibers 12 outer surfaces and this outer covering layer 13 and fill up this plurality of recessed joints, and the material of this outer covering layer 13 is nylon, preferably, this outer covering layer 13 is to drench and be overlying on this layer of fibers 12 outer surfaces cooling forming with the nylon material of hot melt, the nylon material of hot melt can infiltrate in these a plurality of recessed joints for the shape that flows, so as to filling up these a plurality of recessed joints simultaneously bonded to each other with this layer of fibers.

During actual use, please refer to Fig. 1 to Fig. 3 also in the lump with reference to figure 4, automobile-used wire socket 10 provided by the invention is for being installed in outside a bicycle lead 20, wire such as brake wire or shift cable etc. as strength transmission, because must being connected to brake mechanism etc., this bicycle lead 20 locates, therefore this automobile-used wire socket 10 also must extend with this bicycle lead 20, unavoidably need the crooked path to coordinate bicycle lead to extend of appropriateness, and because the present invention adopts glass fibre as layer of fibers 12, the flexibility of this automobile-used wire socket is compared while using wire to be wound around more good, and outer covering layer 13 employing nylon materials have more improved the adhesive power with layer of fibers 12, therefore, when this automobile-used wire socket 10 is crooked, this outer covering layer 13 is difficult for peeling off with this layer of fibers 12, and then maintained the integrity of structure.

By said structure; automobile-used wire socket provided by the invention borrows the layer of fibers of glass fibre to improve crooking ability and recovery capacity; and the outer covering layer of nylon material has improved and glass fibre between adhesive power; make outer covering layer energy close adhesion avoid peeling off in layer of fibers; and; the outer covering layer of nylon material has good scratch resistant property, weatherability and anti-collision ability; can provide splendid protection to inner layer of fibers, inner tube and bicycle lead; and then improved the durability degree using; glass fibre substituted metal more contributes to lightweight, has the effect of progress.
