Description

Bullet formula lock tube flexible rod
Technical field
The utility model relates to a kind of manual flexible rod.
Background technique
When cleaning or whitewashing, often need will manage the shank of instrument is suitably extended from the lower operation that hoists, the while is easy to carry for instrument, and its shank often uses flexible rod.During operation, the interior pipe that stretches out need be fixed, common way is to be provided with the outer lock tube that externally threaded outer tube top is provided with tapped taper, interior pipe is inserted in outer tube and the outer lock tube, by screwing outer lock tube, its inner conical surface is closely contacted with interior pipe, increase the frictional force between the two, play the purpose of fixing interior pipe.This mode China and foreign countries lock tube that is locked should have certain elasticity and toughness, exists fragile outer lock tube in the use, the deficiency that can't accurately locate, and interior pipe easily because of stressed and rotate, displacement, influence the use of instrument.
Summary of the invention
The bullet formula lock tube flexible rod simple in structure, easy to use that the purpose of this utility model provides and a kind ofly can locate, interior Guan Buhui is subjected to displacement.
Technical solution of the present utility model is: it is made up of outer tube, interior pipe, outer lock tube, interior lock tube, interstage sleeve, interior locking ball, outside fix steel ball and location stage clip, and outer tube and interior pipe are the tubular body of hollow, axially are evenly equipped with positioning hole on the inner tubal wall; Interior lock tube is fixed on the externally threaded hollow tubular body of being with on the outer wall of outer tube top for the bottom socket, and its top is provided with male cone (strobilus masculinus), which is provided with compression spring hole radially; Outer lock tube is the hollow taper tubular body that inwall is provided with the internal thread that matches with outside thread, and its inside, top is provided with inner conical surface; Interstage sleeve is the hollow tubular body that is arranged on the outer tube outside and fixedlys connected with outer lock tube bottom; Outside fix steel ball, location stage clip and interior locking ball are installed in the compression spring hole successively.
Be axially arranged with on the male cone (strobilus masculinus) of interior lock tube the symmetry breach, in the compacted process of male cone (strobilus masculinus), the inwall of male cone (strobilus masculinus) can strengthen gradually with the surface of contact of outer wall of inner tube like this, can control and outer wall of inner tube between the frictional force size.
Being provided with and axial cylinder and groove at interval successively on outer lock tube and the contacted inner circle wall of outside fix steel ball, the outside fix steel ball can roll in a circumferential direction and contact with cylinder and groove respectively, on diverse location, can compress the location stage clip in various degree, with the pulling of pipe in controlling.
The vertical cross-section of interior pipe is an octagon.
The inwall of the outer wall on outer tube top and interior lock tube bottom fixedly joins together, the interior pipe of axial uniform positioning hole is inserted in outer tube and the interior lock tube, locking ball and location stage clip are installed in the compression spring hole successively, buckle outer lock tube, in, outside thread is screwed to certain position gradually, interstage sleeve is buckled in the lock tube bottom outside, be screwed into the male cone (strobilus masculinus) of lock tube in its inner conical surface also compresses gradually in the process of outer lock tube, frictional force between interior lock tube and interior pipe phase-contact surface increases, pipe is subjected to displacement in the restriction, axial cylinder and the groove of outer lock tube inwall also can contact with the outside fix steel ball simultaneously, when the outside fix steel ball produces groove to cylinder the time, in the location stage clip compression, interior locking ball jacking in the positioning hole of pipe, lock tube is spacing in relatively can not be pulled and rotate for interior pipe.
The utility model has the advantages that: simple in structure, easy to use, the location is easy, and interior pipe is stressed can not to be rotated and displacement.
