Description

Technical Field

[0001] The utility model belongs to the technical field of knobs, and in particular relates to a rotating mechanism. Background Art

[0002] The knob is a manual component that is turned by hand. According to the functional requirements, it can be divided into continuous multiple rotations, the rotation angle can reach 360°; it can also be used for positioning rotation, etc.

[0003] Conventional knobs require complex structures such as springs, springs, buckles, and locking parts to achieve fixed distances. Since the structures need to support and cooperate with each other, the processing technology is relatively complicated, difficult to assemble, and the overall cost is high.

[0004] In order to solve the above problems, a rotating mechanism is proposed in the present application. Utility Model Content

[0005] In order to solve the above problems existing in the prior art, the utility model provides a rotating mechanism, which has the characteristics of low cost, fixed distance limiting and simple structure.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotating mechanism, including a cylindrical rotating shaft, a rotatable outer sleeve is sleeved on the outside of the rotating shaft, the outer sleeves are multiple and arranged in sequence outside the rotating shaft, marbles are provided at the contact end between the rotating shaft and the outer sleeve, and a spring is provided inside the rotating shaft to limit the outer sleeve on its outside through the marbles.

[0007] As a preferred technical solution of the utility model, the diameter of the rotating shaft is equal to the inner diameter of the outer sleeve, a sink groove with an open end is provided in the rotating shaft, and the spring is located in the sink groove.

[0008] As a preferred technical solution of the utility model, a accommodating space for marbles is also formed in the sink. The diameter of the sink is larger than the marbles, and the marbles enter the sink after being squeezed.

[0009] As a preferred technical solution of the utility model, the inner ring of the outer sleeve is provided with a plurality of limiting grooves which are equidistantly distributed around the circumference, and the marbles are clamped in the limiting grooves by springs.

[0010] As a preferred technical solution of the utility model, the outside of each marble is equally divided into a circle with markings.

[0011] As a preferred technical solution of the utility model, the springs are distributed in the radial direction of the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of the utility model are: a continuous outer sleeve is arranged outside the rotating shaft, and the multiple outer sleeves can fit tightly together. At the same time, a spring, a marble and a limit groove cooperate to play a limiting role, which can not only directly rotate the outer sleeve, but also automatically position it, thereby avoiding the outer sleeve from rotating due to falling, bumping, accidental touching, etc., thereby improving reliability. At the same time, the utility model has a simple structure and low cost, which is conducive to popularization in the fields of timing and decoration. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0020] See also Figure 1-4 The utility model provides the following technical solutions: a rotating mechanism, including a cylindrical rotating shaft 1, a rotatable outer sleeve 2 is sleeved on the outside of the rotating shaft 1, the outer sleeve 2 is multiple and arranged in sequence on the outside of the rotating shaft 1, a marble 4 is provided at the contact end between the rotating shaft 1 and the outer sleeve 2, and a spring 3 is provided inside the rotating shaft 1 to limit the outer sleeve 2 on its outside through the marble 4. In this embodiment, when the assembly is completed, limit members can be set at both ends of the rotating shaft 1, which are not shown in the figure, to prevent the outer sleeve 2 from falling off from the axial direction.

[0021] Specifically, the diameter of the rotating shaft 1 is equal to the inner diameter of the outer sleeve 2. A groove 11 with an open end is provided in the rotating shaft 1. The spring 3 is located in the groove 11. A accommodating space for marbles 4 is also formed in the groove 11. The diameter of the groove 11 is larger than the marbles 4. When the marbles 4 are squeezed, they enter the groove 11. In this embodiment, when the marbles 4 are subjected to external pressure and retreat into the groove 11, the outer sleeve 2 can rotate.

[0022] Specifically, the inner ring of the outer sleeve 2 is provided with a plurality of limiting grooves 21 equidistantly distributed around the circumference, and the marbles 4 are clamped in the limiting grooves 21 by the springs 3. In this embodiment, the limiting grooves 21 have the same number as the external markings of the outer sleeve 2, and they correspond one to one.

[0023] Specifically, each marble 4 has a mark on its outer circumference, which is divided equally into two parts. Figure 1 There are four outer sleeves 2 shown distributed from left to right, and various logos of different shapes and quantities can be set on the outside of each outer sleeve 2 to meet the application of different fields.

[0024] Specifically, the spring 3 is distributed radially in the rotating shaft 1 . In this embodiment, the spring 3 is distributed radially so as to engage the marble 4 with the limiting groove 21 , while the rotation of the outer sleeve 2 is not affected.

[0025] The working principle and use process of the utility model are as follows: the rotating shaft 1 and the outer sleeve 2 are processed and formed and adapted to each other, the rotating shaft 1 is one, and the outer sleeve 2 can be multiple, such as Figure 1 From left to right, the outer sleeve 2 shown in the figure can be provided with the same mark on the outside of each outer sleeve 2, a sink 11 for accommodating the spring 3 and the marble 4 is provided in the rotating shaft 1, and the inner side of the corresponding outer sleeve 2 is provided with the same number of limit grooves 21 as the equal divisions;

[0026] When in use, the outer sleeve 2 is twisted, the marble 4 is disengaged from the inserted limiting groove 21, and then enters the inside of an adjacent limiting groove 21 under the action of the spring 3, and at this time, the mark on the outside of the outer sleeve 2 is switched.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
