fig. 2 is a schematic structural diagram of the present invention.
1. A tower-shaped support sleeve; 2. a stress sleeve; 101. a small through hole; 102. a ball bearing; 201. a small-diameter hole; 202. a large-diameter hole; 203. an open inner wall.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, an embodiment of the present invention is a threaded sleeve for locking a connector, wherein the threaded sleeve is composed of a tower-shaped supporting sleeve 1 and a stress sleeve 2 which are bonded to each other, and the tower-shaped supporting sleeve and the two ends of the stress sleeve are used for locking and connecting the connector, wherein:
one end of the stress sleeve 2 is a small-diameter hole 201, the other end of the stress sleeve is a large-diameter hole 202, and the inner wall of the stress sleeve 2 is provided with an open inner wall 201 structure;
the tower-shaped support sleeve 1 is of a hollow annular structure, and the outer wall of the tower-shaped support sleeve is matched with the inner wall 203 of the opening of the stress sleeve; the wall ring of the tower-shaped support sleeve 1 is provided with a plurality of small through holes 101 which are spaced from each other, the small through holes 101 are positioned on the same horizontal plane, and balls 102 are embedded in the small through holes 101; this tower type support cover 1 is the plastics material, preferably polyoxymethylene material (commonly known as race steel), and ball 102 adopts the steel structure, the internal diameter of little through-hole 101 is less than the diameter of ball 102, makes ball 102 and little through-hole 101 can interference fit, and the ball can remove in little through-hole under the effect of external force.
The ball 102 protrudes out of the wall of the tower-shaped support sleeve 1 towards the axis of the threaded sleeve, the shortest distance from the axis to the ball 102 is smaller than the radius of the small-diameter hole of the stress sleeve 2, the tower-shaped support sleeve is blocked after entering the stress sleeve, the tower-shaped support sleeve orderly moves downwards under the constraint of the stress sleeve, the ball synchronously moves towards the axis, the tower-shaped support sleeve completely enters the stress sleeve, and the distance from the ball to the axis is smaller than the radius of the small-diameter hole of the stress sleeve.
In order to enable the tower-shaped support sleeve 1 and the stress sleeve 2 to be combined more tightly, the structure of the inner open wall 203 is a conical structure, the outer wall of the tower-shaped support sleeve 1 is also a conical structure, when the tower-shaped support sleeve descends, a space can be reserved between the ball and the stress sleeve, locking and buckling are facilitated, the inner wall of the tower-shaped support sleeve 1 is of a cylindrical structure, the diameter of the inner wall is the same as that of the small-diameter hole 201, the tower-shaped support sleeve is filled with glue after entering the inner open wall and is bonded with the small-diameter hole, and the tower-shaped support sleeve and the stress sleeve cannot be dislocated or fall under the condition that no external force is damaged.
During preassembling, the tower-shaped support sleeve with the small through hole is obtained through an integrated injection molding or turning process, the tower-shaped support sleeve on the assembled stress sleeve is stably connected and is not easy to fall off after being bonded on the stress sleeve, and the steel ball of the tower-shaped support sleeve is not easy to loosen and fall off in interference fit with the small through hole.
During site operation, often run into the locking swivel nut of locking plug connector and break down, and traditional locking swivel nut structure is complicated, comprises a plurality of parts, and an organic whole nature is relatively poor, changes that the degree of difficulty is big, inefficiency. The threaded sleeve adopts an integral design, is an integral body after being assembled, is replaced as an integral body during installation, and is convenient and quick to install; and can separate and become the active structure when using, the guarantee stably realizes the locking function. The utility model provides a swivel nut design benefit, its structure not only can stabilize the locking plug connector, more can assemble in advance as a whole, and the direct application is in the job site, and the on-the-spot installation of being convenient for improves the efficiency and the yield of site operation by a wide margin.
The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
