Reason, damper self-locking device easy to use, easy to use, quick for installation, cost performance is high, can permanently use repeatedly, frequent
Grid maintenance, in repairing, substantially save time and the physical efficiency of operator, greatly improve working efficiency, will be effective
Ground changes the existing status for loosening slippage displacement of existing damper.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes screw rod, nut piece, bidirectional ratchet
External member, direction regulating switch；The stud lower end outer wall of the screw rod is equipped with external screw thread, is equipped in the nut of nut piece lower end
Internal screw thread corresponding with external screw thread, nut piece, which is arranged, to be fixed on screw rod, and the outer spiral shell on the internal screw thread and screw rod in nut piece
Line engagement connection；Bidirectional ratchet external member is embedded on the internal ring wall of the nut piece upper end, and bidirectional ratchet external member is set in
Outside the stud of screw rod upper end；The upper surface of the nut piece is connected with direction regulating switch, and direction regulating switch
Set on the rear side of bidirectional ratchet external member.
Further, the bottom end section of the nut piece and screw rod is equilateral hexagon.
After adopting the above structure, the utility model has the beneficial effect that damper self-locking device described in the utility model, makes
With conveniently, quick for installation, cost performance is high, can permanently use repeatedly, in frequent grid maintenance, repairing, substantially save behaviour
Time and the physical efficiency for making personnel, greatly improve working efficiency, will effectively change existing loosen of existing damper and slip
The advantages that status of displacement, the utility model have structure simple, and setting is reasonable, low manufacture cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of screw rod in the utility model.
Fig. 3 is the cross-sectional view of the utility model.
Fig. 4 is the structural schematic diagram of specific embodiment two.
Description of symbols:
Screw rod 1, stud 1-1, external screw thread 1-2, nut piece 2, nut 2-1, internal screw thread 2-2, bidirectional ratchet external member 3, direction
Regulating switch 4, single direction ratchet external member 5.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
Specific embodiment 1:
Referring to as shown in Figure 1-Figure 3, the technical solution adopted in the utility model is: it includes screw rod 1, nut piece 2, two-way
Ratchet external member 3, direction regulating switch 4；The stud 1-1 lower end outer wall of the screw rod 1 is equipped with external screw thread 1-2, and screw rod 1 is
Screw rod 1 made of 45# steel, the nut 2-1 of 2 lower end of nut piece is interior to be equipped with internal screw thread 2-2 corresponding with external screw thread 1-2, nut piece 2
It is arranged and is fixed on screw rod 1, and the internal screw thread 2-2 in nut piece 2 engages connection, nut piece 2 with the external screw thread 1-2 on screw rod 1
For nut piece 2 made of 45# steel；It is embedded with bidirectional ratchet external member 3 on the internal ring wall of 2 upper end of nut piece, and two-way
Ratchet external member 3 is set in outside the stud 1-1 of 1 upper end of screw rod, and bidirectional ratchet external member 3 is bidirectional ratchet external member made of 45# steel
3；The upper surface of the nut piece 2 is connected with direction regulating switch 4, and direction regulating switch 4 is set to bidirectional ratchet set
The rear side of part 3.
Further, the bottom end section of the nut 2 and screw rod 1 is equilateral hexagon.
The working principle of this specific implementation: 1 front end sleeve of screw rod is put at nut 2-1, is passed through bidirectional ratchet external member 3, is pressed
It needs to adjust direction regulating switch 4, rotates clockwise tightening (similarly, counterclockwise rotation can loose unloading), it can be by whole device
Connection, is fixed on specified conducting wire span；Holdback in bidirectional ratchet external member 3 with direction regulating switch 4 adjusting
And change, to achieve the purpose that synchronize fixed self-locking and synchronous loosening disassembly；Only need clockwise or counterclockwise screw rod 1 to receipts
