It is fixed, sliding block is cased with the lead, a spring is provided between the top surface and hollow tube upper end inwall of the sliding block, it is described
Another spring is provided between the bottom surface of sliding block and hollow tube lower end inner wall, the spring housing is on lead.
Antifreeze anticorrosion liquid is inoculated with the hollow tube.
The stiffness factor of two springs is different.
Rubber ring is provided with the wire clamp hole of the wire clamp.
The periphery in the wire clamp hole of the wire clamp is provided with some projections, and the vibration absorber is fixed in projection.
The beneficial effect that the present invention is reached：Conductor combination composition sound folded by the vibration absorber and place wire clamp of the present invention
Sub- crystal structure, when wire is waved, locally resonant will occur for vibration absorber, frequency band gap be produced, so as to reduce wire
Extent of vibration, ensure wire safe operation, the service life of extension lead.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation of vibration absorber.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in figure 1, quadripartion phonon crystal Anti-swing spacing bar, including framework 1, the wire clamp 2 that is arranged on framework 1 and
It is arranged on some to vibration absorber 3 on wire clamp 2, each pair includes two vibration absorbers 3, all vibration absorbers 3 and place wire clamp 2
Folded conductor combination constitutes photonic crystal structure.
Said frame 1 is a square double frame construction, and wire clamp 2, wire clamp 2 and framework 1 are set respectively along its diagonal
Affixed, the periphery in the wire clamp hole 4 of wire clamp 2 is provided with some projections, convex sets composite polygon boss 6（Generally quadrangle is convex
Platform）, wire is through in wire clamp hole 4, and rubber ring 5 is provided with order to reduce in the friction wire clamp hole 4 between wire and wire clamp hole 4.
Above-mentioned two damping devices 3 per centering are oppositely arranged, two damping devices 3 are while be arranged on the top of wire clamp hole 4
Or two damping devices 3 are arranged on the lower section of wire clamp hole 4 simultaneously, vibration absorber 3 can be directly anchored in projection, vibration absorber 3
Including sealed hollow tube 7, lead 8 is provided with hollow tube 7, the central shaft of lead 8 is with the central shaft of hollow tube 7 same
On straight line, the upper and lower end inwall of the two ends of lead 8 respectively with hollow tube 7 is fixed, and sliding block 9 is cased with lead 8, sliding
Block 9 is cylindrical slider 9, is provided with a spring 10 between the top surface and the upper end inwall of hollow tube 7 of sliding block 9, the bottom surface of sliding block 9 with
Another spring 10 is provided between the lower end inner wall of hollow tube 7, the stiffness factor of two springs 10 is different, and spring 10 is enclosed on lead 8
On, for the vibration environment of Optimization Vibration device 3, while damping is increased, make its not perishable icing in the presence of a harsh environment,
Antifreeze anticorrosion liquid 11 is also inoculated with hollow tube 7.
The quantity of vibration absorber 3 can increase in Anti-swing spacing bar, the stiffness factor of spring 10 or cylindrical slider 9
Variable mass, but certain single order natural frequency of vibration of the intrinsic frequency wire of the mechanism of spring 10 and the composition of sliding block 9 must be kept to connect
Closely（Generally first stage and second stage）, it can thus produce multiple LOCALLY RESONANT ELASTIC WAVEs, and then preferably pilot
Wave.
Anti-swing spacing bar is uniformly arranged on transmission pressure, makes wire that there is periodic structure, when wire is waved
When dynamic, due to the locally resonant of vibration absorber 3, it will whole wiring system is produced a range of vibration band gaps, place
It will be suppressed in the propagation of the ripple in this bandgap range, i.e., waving for wiring system will reduce.
By locally resonant concept of the Anti-swing spacing bar based on phonon crystal, by leading folded by vibration absorber 3 and place wire clamp 2
Line combination constitutes photonic crystal structure, when wire is waved, and locally resonant will occur for vibration absorber 3, produces frequency band gap,
So as to reduce the extent of vibration of wire, the safe operation of wire, the service life of extension lead are ensured.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these improve and deformed
Also it should be regarded as protection scope of the present invention.
