Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, the present invention provides a positioning mechanism 100, which includes a rotating sleeve 10, a deformable elastic sleeve 20, and a first rotating shaft 30. One end of the first rotating shaft 30 is inserted into the elastic sleeve 20, and the rotating sleeve 10 is sleeved outside the elastic sleeve 20. The outer wall of the first rotating shaft 30 is provided with a plurality of tooth grooves 31, the elastic sleeve 20 is provided with a first deformation block 21 and a second deformation block 22, and the inner wall of the first deformation block 21 is provided with convex teeth 23 clamped with the tooth grooves 31. By rotating the rotating sleeve 10, the first deformation block 21 is deformed inward, the convex teeth 23 are clamped in the tooth grooves 31, and the second deformation block 22 is deformed inward to press the first rotating shaft 30. Therefore, the first rotating shaft 30 can be locked by the positioning mode of clamping the convex teeth 23 and the tooth grooves 31, the first rotating shaft 30 can be locked by the friction force between the second deformation block 22 and the first rotating shaft 30, double locking is achieved, and the positioning effect is good.
Specifically, the bottom of the elastic sleeve 20 is provided with a positioning column 24, and one end of the first rotating shaft 30 is provided with a positioning hole 32 along the axial direction. When the first rotating shaft 30 is inserted into the elastic sleeve 20, the positioning column 24 is inserted into the positioning hole 32, which makes the elastic sleeve 20 and the first rotating shaft 30 fit more compactly.
Referring to fig. 4 together, the inner wall of the rotating sleeve 10 is opened with a first avoiding groove 11 for avoiding the first deforming block 21. The engagement between the teeth 23 and the teeth grooves 31 is normal. Since the first deformation block 21 is deformable, when the position of the first deformation block 21 corresponds to the first avoidance groove 11, the first rotation shaft 30 is rotated, so that the protruding teeth 23 are separated from the tooth grooves 31, and the first deformation block 21 is deformed outward to enter the first avoidance groove 11, thereby realizing the angle adjustment of the first rotation shaft 30. On the contrary, if the position of the first deformation block 21 does not correspond to the first avoiding groove 11, the first deformation block 21 abuts against the inner wall of the rotating sleeve 10 and cannot be deformed outwards, and the teeth 23 and the tooth grooves 31 cannot be separated and remain locked.
In this embodiment, there are four first deformation blocks 21, which are distributed on the elastic sleeve 20 at equal angles. Correspondingly, there are four first avoidance slots 11. When the first deformation block 21 abuts against the inner wall between two adjacent first avoidance grooves 11, it cannot be deformed outward, and the teeth 23 cannot be separated from the teeth grooves 31, and thus, the locking is maintained.
Referring to fig. 2, the first deformation block 21 is formed by cutting the elastic sleeve 20, and each first deformation block 21 is surrounded by three cutting grooves to form a cantilever structure, which is beneficial to deformation. In order not to interfere with the rotation of the rotating sleeve 10, the first deformation block 21 is deformed around the axis of said elastic sleeve 20. The free end of the first deformation block 21 is also chamfered to facilitate rotation of the rotating sleeve 10.
Further, the outer wall of the second deformation block 22 is provided with a first protrusion 25, and the inner wall of the rotating sleeve 10 is provided with a second avoiding groove 12 for accommodating the first protrusion 25. By rotating the rotating sleeve 10, the first protrusion 25 jumps out of the second avoiding groove 12, the inner wall of the rotating sleeve 10 presses the first protrusion 25, so that the second deformation block 22 deforms inwards to press the first rotating shaft 30, and the first rotating shaft 30 is positioned by using friction.
In this embodiment, there are four second deformation blocks 22, which are distributed on the elastic sleeve 20 at equal angles. Correspondingly, there are also four second avoidance slots 12. When the first projection 25 abuts against the inner wall between two adjacent second avoiding grooves 12, the inner wall of the rotating sleeve 10 presses the first projection 25, so that the second deforming block 22 is deformed inward. The second deformation block 22 is formed by cutting the elastic sleeve 20, and each second deformation block 22 is surrounded by two cutting grooves to form an arch structure, which is beneficial to deformation.
Further, a third deformation block 26 is provided on the elastic sleeve 20, and a third avoiding groove 33 for avoiding the third deformation block 26 is provided on the first rotating shaft 30. The outer wall of third deformation piece 26 is equipped with second lug 27, a plurality of draw-in grooves 13 with second lug 27 complex are seted up to the inner wall of rotatory sleeve 10, and when being extruded by rotatory sleeve 10, third deformation piece 26 is inwards deformed and is got into the third and dodge in the groove 33. The main purpose of the design is that when the rotary sleeve 10 is rotated by hand, the second bump 27 is clamped with one clamping groove 13 when rotating by an angle, so that a 'click' sound or vibration is generated, and the hand feeling is improved.
In this embodiment, there are four third deformation blocks 26, and there are four corresponding second protrusions 27. The number of the clamping grooves 13 is 8, each clamping is carried out, and the clamping grooves rotate 45 degrees, so that the locking and unlocking interval circulation is formed. Further, the first deformation block 21, the second deformation block 22 and the third deformation block 26 are sequentially arranged along the axial direction of the elastic sleeve 20, and are formed by cutting the elastic sleeve 20.

When the mobile phone holder is used, the angle of the clamping mechanism 300 relative to the first supporting rod 200, namely the angle of the mobile phone facing the human body, can be adjusted by rotating the first rotating shaft 30. After the angle is adjusted, the first rotating shaft 30 is locked by the positioning mechanism 100, so that the angle of the mobile phone is locked, and the mobile phone is convenient to watch.
