Abstract
The utility model relates to a locking device, in particular to a flexible tube connection locking device, which comprises a rigid tube and a flexible tube. The utility model is characterized in that: a locking retainer ring is clamped at the joint section of the rigid tube and the flexible tube; the flexible tube is sleeved on the outside of the rigid tube; the locking retainer ring is a round structure. The utility model has the advantages that: the rigid tube is installed in the flexible tube; the locking retainer ring is clamped at the joint section outside the flexible tube; a special attaching device is adopted to press the locking retainer ring longitudinally; the locking retainer ring is made of stainless steel; the expansion property of the locking retainer ring makes the locking retainer ring to shrink longitudinally and lock the flexible tuber on the rigid tube; the locking retainer ring is stressed longitudinally to provide constant and equalized locking force within the scope of 360 degrees, so that the rigid tube and the flexible tube can be connected seamlessly and the gas and fluid can not be leaked. In addition, the locking retainer ring has smooth surface and no concave or convex section, thus overcoming the technical defect that an elastic yoke and a worm yoke bring damage and uneven stress to the flexible tube.
Description
Technical field
The utility model relates to locking device, and particularly a kind of flexible pipe connects locking device.
Background technique
Flexible pipe connects locking device employing flexible collar and worm screw clip at present, although plurality of advantages is arranged, but because the joint of hard tube, flexible pipe is not circumferentially evenly stressed with the clip place of flexible collar or worm screw clip, thereby unbalance stress, form non-seamless link in flexible collar and worm screw clip connected place, often produce gas-liquid herein and leak, this technological deficiency causes a serious accident often.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above technical deficiency, and a kind of easy assembling, non-maintaining is provided, and provides the flexible pipe that continues balanced coupling mechanism force to connect locking device in circumference 360 degree scopes.
The purpose of this utility model is achieved like this:
A kind of flexible pipe connects locking device, comprises hard tube, flexible pipe, and wild card has the locking collar in the joint of hard tube and flexible pipe.
The purpose of this utility model can be achieved like this equally:
A kind of flexible pipe connects locking device, and hose proof is in the hard tube outside.
The purpose of this utility model equally also can be achieved like this:
A kind of flexible pipe connects locking device, the rounded structure of locking collar.
The beneficial effects of the utility model:
1, circumferential stressed seamless link is not leaked.Hard tube is packed in the flexible pipe, go into to lock collar at the joint hose overcoat, withhold device by special use and will lock the collar lateral extrusion, the locking collar is a stainless steel material, utilizes the ductility of self to make locking collar radial contraction, and flexible pipe is locked on the hard tube.The locking collar is a radial force, provides to continue balanced coupling mechanism force in circumference 360 degree scopes, realizes flexible pipe and hard tube seamless link, and gas-liquid can't leak.
2, compactness simple for structure.Flexible collar and worm screw clip yoke configurations take up room, and interfere peripheral component in the assembling.
3, easily assemble non-maintaining.Locking collar surface is slick and sly, no concave-convex, and the clip that has effectively overcome flexible collar and worm screw clip is to the damage of flexible pipe and the technological deficiency of unbalance stress.
