Abstract
The utility model relates to a kind of brake cable.It comprises outer tube (1) and inner tube (2), between described outer tube (1) and inner tube (2), is provided with steel wire (3), and described steel wire (3), at close-packed arrays radially, is axially helical pattern.A kind of brake cable of the utility model, because the steel wire 3 between outer tube 1 and inner tube 2 is radially closely being arranged, be axially helical pattern, therefore effectively increased frictional force, the support force between outer tube 1 and inner tube 2, between outer tube 1 and inner tube 2, be difficult for relative sliding occurs, guaranteed the result of use of mower.
Description
Technical field
The utility model relates to a kind of brake cable, for mower.Belong to gardening device technique field.
Background technology
Mower claims again weeder, grass mower, lawn mower etc.Mower be a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., it is comprised of cutterhead, engine, road wheel, running gear, blade, handrail, control section.Cutterhead is contained on road wheel, and engine is housed on cutterhead, on the output shaft of engine, blade is housed, and blade utilizes the High Rotation Speed of engine aspect speed, to improve a lot, has saved weeding workman's activity duration, has reduced a large amount of human resources.
Brake cable is the vitals of mower, existing brake cable comprises inner and outer tubes, between inner tube and outer tube, be relatively set with two steel wires, the brake cable of this kind of structure, because the frictional force between its inner and outer tubes, support force are inadequate, easily there is relative sliding in inner and outer tubes, can cause like this stopping not tight, affected the result of use of mower.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of brake cable is provided, and this brake cable has increased frictional force, the support force between inner and outer tubes effectively, and inner and outer tubes are difficult for relative sliding occurs, and have guaranteed the result of use of mower.
The purpose of this utility model is achieved in that
A brake cable, comprises outer tube and inner tube, is characterized in: between described outer tube and inner tube, be provided with steel wire, described steel wire, at close-packed arrays radially, is axially helical pattern.
A kind of brake cable of the utility model, its outer tube adopts PP material to make, and inner tube adopts PE material to make.
A kind of brake cable of the utility model, its steel wire has 15 ~ 25, and optimum is 21.
A kind of brake cable of the utility model, the internal diameter of its outer tube is 5.7 ~ 5.8mm, and the external diameter of inner tube is 2.8 ~ 2.9mm, and the internal diameter of inner tube is 2.0 ~ 2.1mm.
Compared with prior art, the beneficial effects of the utility model are:
A kind of brake cable of the utility model, because the steel wire between outer tube and inner tube is radially closely being arranged, be axially helical pattern, therefore effectively increased frictional force, the support force between outer tube and inner tube, between outer tube and inner tube, be difficult for relative sliding occurs, guaranteed the result of use of mower.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of brake cable of the utility model.
Fig. 2 is that the utility model steel wire is at the schematic diagram of axially-aligned.
In figure:
Outer tube 1,
Inner tube 2,
Steel wire 3.
Embodiment
Referring to Fig. 1-2, the utility model relates to a kind of brake cable, it comprises outer tube 1 and inner tube 2, described outer tube 1 adopts PP material to make, and inner tube 2 adopts PE material to make, and between described outer tube 1 and inner tube 2, is provided with steel wire 3, described steel wire 3 is radially closely being arranged, be axially helical pattern, described steel wire 3 has 15 ~ 25, and optimum is 21.
The internal diameter of its middle external tube 1 is 5.7 ~ 5.8mm, and the external diameter of inner tube 2 is 2.8 ~ 2.9mm, and the internal diameter of inner tube 2 is 2.0 ~ 2.1mm.
Operation principle: because the steel wire 3 between outer tube 1 and inner tube 2 is radially closely being arranged, be axially helical pattern, therefore effectively increase frictional force, the support force between outer tube 1 and inner tube 2, between outer tube 1 and inner tube 2, be difficult for relative sliding occurs, guaranteed the result of use of mower.
