As a preferred example, the annular grooves are provided in at least two numbers.

As a preferred example, the openings are provided in four and evenly distributed over the extension.

As a preferred example, the elastic member is a snap ring.

As a preferred example, the elastic member is a rubber band.

As a preferred example, the outer side wall of the nut body is further provided with a plurality of protrusions.

The utility model has the advantages that: the utility model discloses a setting of extension and elastic component extends the screw thread and reduces the thread diameter under the effect of elasticity, has increased the frictional force between the thread to play the locking effect of rotatory bottle.

Drawings

Fig. 1 is a schematic perspective view of the present invention;

fig. 2 is a top view of the present invention;

fig. 3 is a sectional view taken along line a-a of fig. 2.

In the figure: the nut comprises a nut body 1, an extension part 2, an annular groove 3, a convex part 4, an opening 5 and an elastic piece 6.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-3, the locknut for fixing a rotary bottle comprises a nut body 1, wherein one side of the nut body 1 is provided with an extension part 2 with an internal thread, the outer side wall of the extension part 2 is provided with an annular groove 3, an elastic part 6 is sleeved in the annular groove 3, and the extension part 2 is provided with a plurality of openings 5.

At least two annular grooves 3 are arranged, and elastic pieces 6 are arranged in the two annular grooves 3 to ensure enough elasticity to enable the extension part 2 to deform and contract.

The openings 5 are four and are uniformly distributed on the extension part 2, so that the extension part 2 deforms and contracts uniformly, and the sealing performance is improved.

The elastic element 6 is a snap ring.

The elastic member 6 is a rubber band.

The outer side wall of the nut body 1 is also provided with a plurality of convex parts 4.

The working principle is as follows: when the anti-loosening rotary bottle is used, the nut is sleeved on the rotary shaft of the rotary evaporator in advance, when the rotary bottle is installed on the rotary shaft, the anti-loosening nut is conveniently rotated through the boss 4, the anti-loosening nut is rotated to the joint of the rotary shaft and the rotary bottle to be fixed, the diameter of the thread of the extension part 2 is reduced under the elastic force action of the elastic piece 6, the friction force between the threads is increased, and therefore the anti-loosening effect of the rotary bottle is achieved.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
