An embodiment of the utility model provides an elasticity twist grip is suitable for and switches between non-rotating state and rotating state, can realize rotatory end position to promote the rotatory of rotatory action and feel.

Fig. 1 is an exploded view of a flexible rotary handle 10 according to an embodiment of the present invention. An elastic twist grip 10 according to an embodiment of the present invention is described below with reference to fig. 1.

As shown in fig. 1, the elastic rotary handle 10 includes an upper rotary body 11, a support body 12, and a lower rotary body 13, wherein the support body 12 is located between the upper rotary body 11 and the lower rotary body 13. After assembly, the lower rotator 13 is connected to the upper rotator 11, and both may rotate together after connection.

Specifically, as shown in fig. 2a to 2b, there are respectively a schematic plan view and a perspective view of the upper rotating body 11 of the elastic rotating handle 10 in the embodiment shown in fig. 1. As shown in fig. 2a to 2b, the lower surface of the upper rotating body 11 has a plurality of grooves 110.

Further, as shown in fig. 3a to 3b, a plan view and a perspective view of the support body 12 of the elastic rotary handle 10 in this embodiment are shown. As shown in fig. 3a to 3b, the upper surface of the support 12 has a plurality of elastic arms 121, and the elastic arms 121 are U-shaped, and one end (root) of each elastic arm is integrated with the upper surface of the support 12 while the U-shaped portion of the other end (head) is separated from the upper surface. The head end of each spring arm 121 has a wave point 120.

As described above, in this embodiment, the elastic rotary handle 10 is adapted to be switched between the non-rotating state and the rotating state.

In the non-rotating state, the plurality of wave points 120 on the plurality of elastic arms 121 on the upper surface of the supporting body 12 are embedded in the plurality of grooves 110 on the lower surface of the upper rotating body 11. After insertion, the jamming of the wave points and grooves prevents the upper and

lower rotors

11 and 13 from rotating freely with respect to the support body 12.

As shown in fig. 2 a-3 b, the number of wave points 120 is less than or equal to the number of grooves 110.

In a rotating state, for example, when the upper rotating body 11 is manually rotated, the upper rotating body 11 and the lower rotating body 13 rotate together with respect to the supporting body 12. During rotation, each wave point 120 moves downward (e.g., in the X direction as shown in fig. 1) and away from each groove 110 in which each wave point 120 was embedded prior to the rotating action. At this time, the plurality of elastic arms 121 are deformed downward (e.g., in the X direction as shown in fig. 1) by the downward moving pressure of the wave point 120, so that each wave point 120 rubs against the lower surface of the upper rotating body 11 under a predetermined pressure until the plurality of wave points 120 are again inserted into the plurality of grooves 110, the predetermined pressure disappears, the plurality of elastic arms 121 are restored, and the elastic rotating handle 10 is again returned to the non-rotating state.

The predetermined pressure may depend on a plurality of parameters or influence factors, including but not limited to the material of the surface groove 110 of the upper rotating body 10, the material of the elastic arm 121, the size of the wave point 120, etc., and the present invention is not limited to this predetermined pressure. In practical application, the parameters can be quantitatively selected and configured according to the required rotating hand feeling and the like.

In some embodiments of the present invention, a sufficient rotation space is reserved between the upper rotating body 11 and the lower rotating body 13, the rotation space is suitable for the support body 12 to move in the axial direction, and the rotation space may not need to be too large, so as to form an effect that the support body 12 is suspended between the upper rotating body 11 and the lower rotating body 13.

As shown in fig. 1, the lower rotator 13 is coupled to the upper rotator 11 by a fastener 14. In the embodiment shown in fig. 1, the fasteners 14 are three screws. However, the present invention is not limited to this, and other types of fasteners or other fixing methods may be selected to connect the upper rotator 11 and the lower rotator 13 in practical applications.

Further, as shown in fig. 3a to 3b, a window 122 is further opened at the center of the support 12. As shown in fig. 1, three fasteners 14 may pass through the window 122 to connect the upper rotator 11 and the lower rotator 13.

Fig. 4 is a perspective view of the lower rotator 13 of the elastic rotary handle 10 in this embodiment. As best seen in fig. 4, the lower rotating body 13 has a plurality of screw holes 130 through which the plurality of fastening members 14 pass to connect the lower rotating body 13 to the upper rotating body 11. Correspondingly, as shown in fig. 2a to 2b, the lower surface of the upper rotating body 11 also has a plurality of openings 114 to provide a fastening position for fastening the fastener.

More specifically, as shown in fig. 4, the lower rotator 13 further has a second connection portion 131 on the upper surface thereof. Correspondingly, as shown in fig. 2a to 2b, the lower surface of the upper rotating body 11 also has a first connecting portion 111. In this embodiment, the second connection portion 131 is in a ring shape protruding from the upper surface of the lower rotating body 13, and the second connection portion 131 in the ring shape may pass through the window 122 formed in the central position of the supporting body 12 as shown in fig. 3a to 3b and finally contact the first connection portion 111.

In some embodiments of the present invention, the outer diameter of the second connecting portion 131 is only slightly smaller than the inner diameter of the window 122, so that the second connecting portion 131 can function as a limit, i.e., when the upper rotating body 11 and the lower rotating body 13 rotate together relative to the supporting body 12, the two rotating bodies do not deviate too much from the center of the supporting body 12.

More specifically, in this embodiment, as shown in fig. 4, the second connecting portion 131 further includes a plurality of stoppers 132. Correspondingly, as shown in fig. 2a to 2b, the first connecting portion 111 also has a plurality of limiting regions 112, and when the second connecting portion 131 contacts the first connecting portion 111, the plurality of limiting blocks 132 can be limited to move in the limiting regions 112, thereby facilitating alignment of the upper and lower rotating bodies with each other when the elastic rotary handle 10 is installed, and improving stability of the rotating operation in practical use.

As shown in fig. 2a to 2b, in the present embodiment, the edge of the upper rotating body 11 has a handle 113 so that the rotating operation can be facilitated.

As shown in fig. 2a to 2b, the lower surface of the upper rotating body 11 has elasticity, and especially, the annular region 1100 where the plurality of grooves 110 are located is made of an elastic material, so that the friction hand feeling during the rotating process can be improved, and the rotating experience can be improved.

Illustratively, in some embodiments of the present invention, the upper rotating body 11 is formed by two-material injection molding. That is, the outer surface portion 1111 may be formed by injection molding of a plastic material, and the annular region 1100 where the plurality of grooves 110 are located may be formed by injection molding of TPU (Thermoplastic polyurethane elastomer), so that the friction feeling during the rotation process may be realized while the upper rotating body 11 having a certain strength is provided.

Similarly, in some embodiments of the present invention, the wave point 120 and the elastic arm 121 of the supporting body 12 can be made of plastic with better elasticity and wear resistance, so as to enhance the rotating hand feeling.

In the embodiment shown in fig. 1, the resilient swivel handle 10 further comprises a base 15, the base 15 may carry the lower swivel 14.

More specifically, when the base 15 carries the lower rotator 13, the base 15 is also connected to the support body 12 by a plurality of fasteners 16. As can be seen in fig. 1, a plurality of fasteners 16 may be threaded through a plurality of openings 150 in the base 16 and a plurality of openings 151 in the support body 12 during assembly.

In some embodiments of the present invention, the base 15 can also be connected to a plurality of devices in a general structure, so that the present invention provides a more convenient elastic rotating handle that directly acts on the devices and performs the rotating action.

In some other embodiments of the present invention, an opening for the plurality of fastening members 16 to be tightened is reserved on the lower surface of the upper rotating body 11, so that the base is sequentially connected to the supporting body 12 and the upper rotating body 11.

To more clearly show the structure of a resilient twist grip of the present invention, fig. 5 shows a cross-sectional view of a resilient twist grip 10 along the direction a-a as shown in fig. 1. As shown in fig. 5, in the non-rotation state, the wave point 120 is embedded in the groove 110 and the elastic arm 121 is not deformed by the force.

The above is an explanation of an elastic rotating handle according to an embodiment of the present invention. Adopt this elasticity twist grip can realize rotatory end position to promote the rotatory of rotatory action and feel, simultaneously, compared with prior art, practiced thrift cost such as mould expense, five metals pivot expense, also practiced thrift the cost when obtaining rotatory feeling.
