Abstract
The utility model discloses a double -deck reverse coil spring cable, including outside spring and inside cable, inside cable is located outside spring, the winding direction of outside spring each other is reverse with the winding direction of inside cable. The beneficial effects of the utility model are that: adopt bilayer structure, outerly be that pitch is little, the winding closely, around the great metal spring in footpath, the inlayer be that pitch is big, the winding is sparse, around the less cable in footpath, outer spring is reverse with the winding direction of inlayer cable is mutual, guarantees that outer metal and inlayer cable never twine. This cable is connected conveniently, and the transmission is stable, long service life, various exceedingly odious environment can be applied to to the sexual valence relative altitude, are applicable to the concertina type, rotary -type equipment is connected, robot line front end the for especially, can effectively avoid scraping bump, incident that cable such as broken string brought, the security height, the practicality is strong.
Description
Technical field
This utility model relates to a kind of cable with outer protection spring, belongs to cable technique neck
Territory.
Background technology
Cable has control installation, connection equipment, the multiple action such as transmit electric power, including inside
Conductor and external insulation and outer protection structure, in prior art, the outer protection structure of cable is adopted more
It is the patent application of 201510119718.7 with the design of oversheath form, such as number of patent application
File, discloses a kind of cable, including the sheath being arranged in external shroud.Said structure
Cable is easily wound into together, disassembles and wastes time and energy, and above-mentioned cable be not suitable for concertina type,
Rotary device, especially robot front end line, as used the cable of said structure, easily produce
Raw scratching, broken string, bring potential safety hazard.
Utility model content
For solving the defect that prior art exists, the purpose of this utility model is to provide a kind of double-deck
Reverse helical spring cable, it is adaptable to concertina type, rotary device connect, and can be prevented effectively from and scrape
The potential safety hazard that touch, broken string etc. causes.
The technical solution of the utility model is: a kind of double-deck reverse helical spring cable, including outside
Portion's spring and Internal cable, in the externally-located spring of Internal cable, the winding of described external springs
Direction is the most reverse with the winding direction of Internal cable.
Described external springs uses memory metal material to make.
The pitch of described external springs is less than the pitch of Internal cable.
The winding compactness of described external springs is more than the winding compactness of Internal cable.
Described external springs is 10-15 times of wire diameter around footpath.
Described external springs is identical with the bearing of trend of Internal cable.
It is respectively equipped with insulating barrier on described Internal cable and external springs.
The beneficial effects of the utility model are: use double-decker, and outer layer is that pitch is little, is wound around
Closely, bigger around footpath metal spring, internal layer is that pitch is big, it is sparse, less around footpath to be wound around
Cable, outer layer spring is the most reverse with the winding direction of internal layer cable, it is ensured that outer layer metal is with interior
Layer line cable is never wound around.This cable is easy to connect, and transmission is stable, and service life is long, cost performance
Height, can be applicable to various extreme environment, it is adaptable to concertina type, rotary device connect,
Especially robot front end line, can be prevented effectively from the safe thing that the cable such as scratching, broken string brings
Therefore, safety is high, practical.
Accompanying drawing explanation
This utility model has accompanying drawing 2 width.
Fig. 1 is structure chart of the present utility model；
Fig. 2 is application drawing of the present utility model.
In figure, reference is as follows: 1, external springs, and 2, Internal cable, 3, robot.
Detailed description of the invention
This utility model is described further by 1-2 below in conjunction with the accompanying drawings:
A kind of double-deck reverse helical spring cable, including the outside using memory metal material to make
Spring 1, in the externally-located spring of Internal cable 21, the winding direction of described external springs 1
The most reverse with the winding direction of Internal cable 2.
The pitch of described external springs 1 is less than the pitch of Internal cable 2.
The winding compactness of described external springs 1 is more than the winding compactness of Internal cable 2.
For ensureing pliability and the tensile force of spring, described external springs 1 is spring wire around footpath
10-15 times of diameter.
Described external springs 1 is identical with the bearing of trend of Internal cable 2.
It is respectively equipped with insulating barrier on described Internal cable 2 and external springs 1.
The reverse helical spring cable of this bilayer is applicable to concertina type, rotary device connects, especially
It is the front end line of robot 3, the safe thing that the cable such as scratching, broken string brings can be prevented effectively from
Therefore；Using double-decker, outer layer is that pitch is little, is wound around tight, bigger around footpath metal spring,
Internal layer is that pitch is big, is wound around cable sparse, less around footpath, external springs 1 and Internal cable
The winding direction of 2 is the most reverse, it is ensured that outer layer metal is never wound around with internal layer cable, and uses
During external springs 1 self winding will not occur, eliminate because of necessary to wound upon themselves
Disassemble link, improve service efficiency.This cable is easy to connect, and transmission is stable, and service life is long,
Cost performance is high, can be applicable to various extreme environment.
The above is only preferred implementation of the present utility model, it is noted that for this skill
For the those of ordinary skill in art field, in the premise without departing from this utility model know-why
Under, it is also possible to making some improvement and modification, these improve and modification also should be regarded as this practicality newly
The protection domain of type.
