Background technique

Line traffic control flexible pipe all has application in multiple line traffic control field, and as motorcycle brake line traffic control flexible pipe, bicycle brake line traffic control flexible pipe and bathroom line traffic control flexible pipe etc., its structure is roughly the same.At present, the line traffic control flexible pipe of the sanitaryware used on the market is made up of inner core and outer tube two parts mostly, the steel wire (similar fried dough twist rope structure) that inner core is woven into stock by kink usually combines, outer tube is combined by HDPE+ braided steel wire netting twine+HDPE three layers usually, the kink of many steel wires is woven into when inner core that stock combines is applied in small space can go out to bend difficulty, the problem of pliability deficiency, and outer tube cause its complex process by the net line structure of many braided steel wires, with high costs.

Model utility content

The purpose of this utility model is for the problems referred to above deficiency, provides that a kind of structure is simple, lower, the pliable and tough durable novel line traffic control flexible pipe of cost, meets the X-by-Wire requirement of sanitaryware special space.

In order to achieve the above object, the utility model is by the following technical solutions:

Novel line traffic control flexible pipe, comprises outer tube and can the inner core that slides of chamber within the outer tube, described outer tube is outer by LDPE, wire spiral middle level and inner plastic three-decker form; And described inner core is wire spiral inner core.

Further, described inner plastic is HDPE inner tube, or is POM inner tube.

Further, institute's wire spiral middle level is steel wire spiral line middle level, or is iron wire helix middle level.

Further, institute's wire spiral inner core is steel wire spiral line inner core, or is iron wire helix inner core.

As preferably, the two ends of described outer tube are fixed with erection joint, and described erection joint inside is provided with for the through hole by inner core.

The length of described inner core is greater than the length of outer tube.

Novel line traffic control flexible pipe described in the utility model, structure is simple, cost is lower, pliable and tough durable, meets the X-by-Wire requirement of sanitaryware special space.

Accompanying drawing explanation

Fig. 1 is that novel line traffic control hose construction described in the utility model partly cuts open figure.

Fig. 2 is the sectional view of novel line traffic control flexible pipe described in the utility model.

Fig. 3 is the structural representation that novel line traffic control flexible pipe described in the utility model increases erection joint.

Below by way of the drawings and specific embodiments, the utility model is further described:

Embodiment

As shown in Figures 1 to 3, novel line traffic control flexible pipe described in the utility model, is mainly used in the application of sanitaryware line traffic control, but also can be used as supporting in the application such as motorcycle brake line traffic control, bicycle brake line traffic control.The inner core 2 that novel line traffic control hose package described in the utility model is drawn together outer tube 1 and can be slided at outer tube 1 inner chamber, the length of described inner core 2 is greater than the length of outer tube 1.Its main structure is as follows:

As illustrated in fig. 1 and 2, described outer tube 1 is made up of LDPE skin 11, wire spiral middle level 12 and inner plastic 13 three-decker; LDPE outer 11 with comprise tubing at the combined process in wire spiral middle level 12 and wrap up and overlap beer two kinds.Described inner plastic 13 is HDPE inner tube, or is POM inner tube; Wire spiral middle level 12 adopts wire spiral winding composition, spring-like shape and structure, and existing line traffic control flexible pipe middle level adopts braided steel wire netting twine, similar netted structure, existing have line traffic control flexible pipe media layer damage and technique relative complex, cost is higher, and suppleness is also not as good as the wire spiral middle level 12 that the utility model adopts.Wire spiral middle level 12 described in the utility model is steel wire spiral line middle level, or is iron wire helix middle level.Further, described inner plastic 13 is HDPE inner tube, or is POM inner tube.

Described inner core 2 is wire spiral inner core, and particularly, institute's wire spiral inner core is steel wire spiral line inner core, or is iron wire helix inner core.Wire spiral inner core adopts wire spiral winding composition, spring-like shape and structure, and technique is simple, cost is lower and suppleness is very good.And existing line traffic control flexible pipe inner core to be the kink of many steel wires be woven into stock combines, similar fried dough twist rope structure, can go out to bend difficulty when being applied in small space, the problem of pliability deficiency.

As shown in Figure 3, the two ends of described outer tube are fixed with erection joint 3, and described erection joint 3 inside is provided with for the through hole by inner core, and novel line traffic control flexible pipe described in the utility model can match the erection joint of different size and structure according to different application scenarios.

Apply in concrete line traffic control and be, utilize the bending of outer tube 1 and pliability, force wire spiral inner core to follow the track of outer tube 2 to bend, outer tube 1 is fixed by two ends erection joint 3 and external control structure.When external control structure implements pulling force or pressure to wire spiral inner core, wire spiral inner core can follow the bending path implementation slip transmission of outer tube 2, thus realizes the function of corresponding line traffic control.

Compared with prior art, tool has the following advantages and beneficial effect the utility model:

1. the utility model outer tube middle level is worked out without the need to adopting Steel Wire Strand, and only need a wire spiral fit to form, structure is simple, with low cost;

2. the utility model inner core is a wire spiral, compares the fried dough twist structure inner core that existing employing many steel wire kinks are woven into stock, its bending and better applicable more occasion of pliability;

3, the outer inner tube layer material of the utility model is HDPE or POM, and smooth surface, wear resistance are good effectively can extend the flexible axle friction life-span.
