Abstract
The present utility model belongs to field of mechanical technique, specifically a kind of metal washer with locking plate, can be widely used in military, civil transport rigid rod driving mechanism joint is locking.A kind of metal lock washer, with locking plate on packing ring hole wall, when packing ring two ends do not bend, locking plate can move in the groove of stay-bolt joint, does not affect the adjustment of pull bar length; After the bending of packing ring two ends, two bending sides of packing ring are fitted in pull bar sleeve respectively and eliminate on the nut hex surface of thread pitch, are connected by the nut of pull bar sleeve, stay-bolt joint and elimination thread pitch, have good anti-loosening property.
Description
Technical field
The present utility model belongs to field of mechanical technique, specifically a kind of metal washer with locking plate, can be widely used in military, civil transport rigid rod driving mechanism joint is locking, is not suitable for rigid torsion bar driving mechanism joint locking.
Background technique
Military, civil transport rigid control linkage adopts pull bar transmission or torsion bar transmission.In rigid rod driving mechanism, connect with pull bar between driving rocker.For ensureing that driving mechanism, in movement process, the phenomenon such as bite, retardance does not occur, need adjustment pull bar length when debugging mechanism.Traditional pull bar is assembled by screwed joint, sleeve, pipe, and screwed joint is connected together by screw-thread fit and sleeve, and eliminates thread pitch with nut, and sleeve and pipe tubular-shank rivet connect together (see Fig. 1); Pull bar under vibration transmission time, easily loosen for the nut eliminating thread pitch, cause pull bar length to change, affect the reliably working of mechanism.Therefore, need to design new anatomical connectivity form, make the nut of elimination thread pitch be not easy to loosen, thus improve the reliability of mechanism.
Summary of the invention
Object of the present invention: provide a kind of nut pull bar being eliminated thread pitch that makes and be not easy to loosen, do not affect again the metal washer of pull bar installment and debugging.
Technological scheme of the present invention:
A kind of metal lock washer, with locking plate on packing ring hole wall, when packing ring two ends do not bend, locking plate can move in the groove of stay-bolt joint; After the bending of packing ring two ends, two bending sides of packing ring are fitted in pull bar sleeve respectively and eliminate on the nut hex surface of thread pitch.
The width of described locking plate is consistent with the width of the groove of stay-bolt joint.
Described locking plate is rectangle, and the groove of stay-bolt joint is also rectangle groove.
Described metal lock washer adopts No. 20 steel.
The linkage structure of a kind of pull bar sleeve and stay-bolt joint, comprise: the nut of pull bar sleeve, stay-bolt joint and elimination thread pitch, wherein, stay-bolt joint is by screw thread and pull bar sleeve connection, stay-bolt joint also has the nut eliminating thread pitch, there is hex surface the exterior edge face of pull bar sleeve.Also comprise the metal lock washer between the nut eliminating thread pitch and pull bar sleeve.
Beneficial effect of the present invention: effectively utilize this metal lock washer, with the locking plate of packing ring and crimp locking, neither affect the installment and debugging of pull bar, solving again rigid rod mechanism makes pull bar length change because pull-rod nut loosens, and causes mechanism that the problem of the mechanical failure such as bite, retardance occurs.

Wherein, 1-stay-bolt joint, 2-nut, 3-metal lock washer, 4-sleeve.
Embodiment
Below in conjunction with Fig. 3 and embodiment, the present invention is described in further detail:
A kind of metal lock washer, with locking plate on packing ring hole wall, when packing ring two ends do not bend, locking plate can move in the groove of stay-bolt joint, does not affect the adjustment of pull bar length; After the bending of packing ring two ends, two bending sides of packing ring are fitted in pull bar sleeve respectively and eliminate on the nut hex surface of thread pitch, are connected by the nut of pull bar sleeve, stay-bolt joint and elimination thread pitch, have good anti-loosening property.
The width of described locking plate is consistent with the width of the groove of stay-bolt joint.
Described locking plate is rectangle, and the groove of stay-bolt joint is also rectangle groove.
Metal lock washer adopts No. 20 steel, shaping by special mould punching.
The linkage structure of a kind of pull bar sleeve and stay-bolt joint, comprise: the nut of pull bar sleeve, stay-bolt joint and elimination thread pitch, wherein, stay-bolt joint is by screw thread and pull bar sleeve connection, stay-bolt joint also has the nut eliminating thread pitch, there is hex surface the exterior edge face of pull bar sleeve.Also comprise the metal lock washer between the nut eliminating thread pitch and pull bar sleeve.
This metal lock washer, locking plate is inserted in the rectangle groove of stay-bolt joint, after pull bar debugging terminates, the nut screwing clamping of thread pitch will be eliminated, again one end of this packing ring bending is fitted with a face in pull bar sleeve hex surface, the other end bending is fitted with a face in nut hex surface, thus limit pull bar sleeve, relatively rotating between stay-bolt joint and the nut eliminating thread pitch, guarantee that pull bar length does not change, avoid the unexpected bite of mechanism and block the mechanical failure caused.
