Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 1 to 4, the technical solution provided by the present invention is: a multi-level locking ring comprises a first locking ring 1 and a second locking ring 2 which are integrally connected, wherein the second locking ring 2 comprises at least one locking joint 3 which is integrally connected.
Referring to fig. 2 and 3, a suitable locking segment 3 is selected; a plurality of locking sections 3 in the second locking ring 2 are in a step shape with gradually enlarged inner diameter away from the first locking ring 1; when the locking device works specifically, the first locking ring 1 is sleeved on the rotating shaft, then a product is connected with the rotating shaft, and the first locking ring 1 is pushed to a proper position, so that the product is sleeved on the locking section 3 with a proper size.
Fixing the product through a locking mechanism; the locking section 3 comprises a locking ring 31, the outer side wall of the locking ring 31 is in threaded connection with a threaded ring 32, the inner side wall of the threaded ring 32, which is far away from the first locking ring 1, is provided with an inclined notch 33, and the inner side wall of the threaded ring 32 is uniformly provided with locking mechanisms 34 along the circumferential direction;
the locking mechanism 34 comprises an arc-shaped groove 341 arranged on the inner side wall of the locking ring 31, a locking rod 342 is uniformly arranged at the position of the locking ring 31 corresponding to the arc-shaped groove 341, the locking rod 342 penetrates through the locking ring 31, the upper end of the locking rod 342 is rotatably connected with a ball 343, and the ball 343 is attached to the inclined inner side wall of the threaded ring 32;
vertical force: the lower end of the locking lever 342 is connected with a locking arc plate 344, an auxiliary spring 345 is arranged between the locking arc plate 344 and the inner wall of the arc-shaped groove 341, the auxiliary spring 345 corresponds to the locking lever 342, the locking lever 342 passes through the middle part of the auxiliary spring 345, a first rubber pad 346 is sleeved on the inner wall of the locking arc plate 344, and an auxiliary part 35 is arranged on one side of the locking arc plate 344 close to the first locking ring 1; during specific work, the threaded ring 32 on the locking joint 3 with a proper size is rotated, the inner side wall of the threaded ring 32 with the inclined notch 33 drives the locking rod 342 to move towards the direction close to the center of the locking ring 31 through the ball 343, and in the process, the locking rod 342 drives the first rubber pad 346 to be attached to the surface of a product through the locking arc plate 344, so that the product is fixed in the vertical direction.
Force of inclination angle: the auxiliary member 35 includes an arc-shaped inclined plate 351 connected to the locking arc plate 344, and a second rubber pad 352 is sleeved on a lower end of the arc-shaped inclined plate 351.
The inner wall of the second rubber pad 352 is flush with the inner wall of the first rubber pad 346; in the process of fixing the product by the force in the vertical direction, the force of an inclined angle is generated by the auxiliary piece 35, so that the second rubber pad 352 is also attached to the surface of the product, the fixing force of the product is implemented by the inclined angle, and the fixing stability of the locking joint 3 on the product is further guaranteed.
Further, the height difference of the inclined cut 33 is greater than the height difference of the step between the adjacent locking sections 3, and the height difference of the inclined cut 33 of the threaded ring 32 ensures that the distance that the locking rod 342 moves towards the center of the locking ring 31 is greater than the adjusting height in the rotating range of the threaded ring 32, and ensures that the locking rod 342 can be in contact with the surface of a product through the first rubber pad 346 and the second rubber pad 352 and is locked and fixed.
Referring to fig. 3 and 4, the first locking ring 1 and the locking segment 3 have the same structure, and the auxiliary member 35 of the first locking ring 1 is disposed at a side close to the second locking ring 2; in a specific operation, since the direction of the auxiliary member 35 in the first locking ring 1 is opposite to that of the auxiliary member 35 in the plurality of locking segments 3 in the second locking ring 2, in an integral state, there is an opposite force to ensure the stability of the whole, and in the pair of opposite forces, each force is opposite to that of the corresponding operating object, that is, in the first locking ring 1, the auxiliary member 35 can prevent the first locking ring 1 from moving to a side close to the rotating shaft, and in each locking segment 3 of the second locking ring 2, the auxiliary member 35 can prevent the second locking ring 2 from moving to a side away from the rotating shaft.
