DETAILED DESCRIPTION
[0036] The utility model will be described in detail below with reference to the accompanying drawings:
[0037] Example: As attached Figures 1 to 17 As shown, a rotatable motion mechanism includes a main body 1, a connecting part 2, a movable groove 21, a first arc surface 211, a second arc surface 212, an intermediate positioning arc surface 213, a first convex surface 214, a second convex surface 215, a positioning column 22, a handle front shell 3, a central slot 31, a semicircular arc surface 311, a side slot 32, a groove 33, a locking hole 34, a slide groove 35, a handle rear shell 4, a support stop 41, a plastic rotating ring 5, an ear 51, a boss 52, a fixed terminal 6, a flange 61, a locking screw 7, a riveting block 8, a central pillar 81, an arc-shaped recess 811, a side pillar 82, a protrusion 83, a fixing screw 9 and a handle bottom shell 10.
[0038] Reference Figure 1 A connecting part 2 is provided at the lower part of the main body 1, and a handle is rotatably connected to the connecting part 2. The handle is formed by a handle front shell 3 and a handle rear shell 4, and a handle bottom shell 10 is fixed to the bottom of the handle. Fig.10 As shown, movable grooves 21 are symmetrically provided on the left and right sides of the connecting portion 2 , and a plastic rotating ring 5 is relatively rotatably installed in each movable groove 21 .
[0039] like Figure 4 As shown, ears 51 are symmetrically arranged on both sides of the outer wall of the plastic rotating ring 5, and two bosses 52 are arranged on the surface of the plastic rotating ring 5, and the bosses 52 are symmetrically arranged on one side surface of the plastic rotating ring 5, and the line between the two ears 51 is perpendicular to the line between the two bosses 52. Fig.10 As shown, the movable groove 21 adopts a rotationally symmetrical structure, and the first arc surface 211, the first convex surface 214, the middle positioning arc surface 213, the second convex surface 215 and the second arc surface 212 are sequentially arranged along the inner wall of the movable groove 21, which can match and position the ear 51 of the plastic rotating ring 5. Among them, the distances from the first arc surface 211, the middle positioning arc surface 213 and the second arc surface 212 to the center of the movable groove 21 are all matched with the distance from the outer wall of the ear 51 to the center of the plastic rotating ring 5 (that is, the plastic rotating ring 5 will not be deformed when passing through), and the distances from the first convex surface 214 and the second convex surface 215 to the center of the movable groove 21 are both smaller than the distance from the outer wall of the ear 51 to the center of the plastic rotating ring 5, so that the plastic rotating ring 5 will be deformed when passing through.
[0040] like Figure 1 , 2 As shown, riveting blocks 8 are symmetrically arranged on both sides of the handle, and the riveting blocks 8 are locked after being slot-matched with the front shell 3 of the handle, so as to press the boss 52 and the front shell 3 of the handle tightly. Fig.10 As shown, a positioning column 22 is provided at the center of the movable groove 21, and the fixed terminal 6 is positioned and installed on the positioning column 22 by means of a locking screw 7. When the handle rotates relative to the connecting portion 2, the riveting block 8 is driven to rotate around the fixed terminal 6, and the plastic rotating ring 5 is driven to be in the first positioning position (such as Fig.13 As described above, the plastic rotating ring 5 is at 0°), the second positioning position (such as Fig.15 As shown, the plastic rotating ring 5 is at 45°) and the third positioning position (as shown Fig.17 As shown, the plastic rotating ring 5 rotates between three positions of 90°.
[0041] Reference Fig.13 When the plastic rotating ring 5 is in the first positioning position (i.e., the initial state), the two ears 51 are in contact with the first arc surface 211, ensuring the stability of the position of the plastic rotating ring 5, thereby achieving the stability of the handle at this angle, and the line between the two ears 51 is parallel to the horizontal plane. At this time, the angle between the handle and the horizontal plane is 90° (such as Figure 6 shown).
[0042] Reference Fig.14 When the plastic rotating ring 5 is between the first positioning position and the second positioning position (i.e., the angle of the plastic rotating ring 5 relative to the horizontal plane is in the range of 0 to 45°), the two ears 51 are in contact with the first convex surface 214, causing the plastic rotating ring 5 to deform and take on an elliptical deformation state.
[0043] like Fig.15 As shown, when the plastic rotating ring 5 is in the second positioning position (intermediate positioning state, that is, the angle of the plastic rotating ring 5 relative to the horizontal plane is 45°), the two ears 51 are both inserted into the intermediate positioning arc surface 213, ensuring the stability of the position of the plastic rotating ring 5, thereby achieving the stability of the handle at this angle. At this time, the angle between the handle and the horizontal plane is 45°.
[0044] like Fig.16 As shown, when the plastic rotating ring 5 is between the second positioning position and the third positioning position (i.e., the angle of the plastic rotating ring 5 relative to the horizontal plane is in the range of 45 to 90°), the two ears 51 are in contact with the second convex surface 215, causing the plastic rotating ring 5 to deform and present an elliptical deformation state again.
[0045] Reference Fig.17 When the plastic rotating ring 5 is in the third positioning position (fully folded state, that is, the angle of the plastic rotating ring 5 relative to the horizontal plane is 90°), the two ears 51 are in contact with the second arc surface 212, ensuring the stability of the position of the plastic rotating ring 5, thereby achieving the stability of the handle at this angle, and the line between the two ears 51 is perpendicular to the horizontal plane. At this time, the angle between the handle and the horizontal plane is 0°.
[0046] Further, such as Figure 2 , 5 As shown in FIGS. 8 and 9, a side support 82 is symmetrically arranged on both sides of the riveting block 8, and a side slot 32 is provided at a position corresponding to the side support 82 on the front shell 3 of the handle, and a boss 52 and a side support 82 are correspondingly inserted into each side slot 32, so that the side support 82 presses the boss 52 tightly into the side slot 32. A central support 81 is provided between the side supports 82 on both sides of the riveting block 8, and a central slot 31 is provided between the two side slots 32 of the front shell 3 of the handle, and the central support 81 is correspondingly inserted into the central slot 31. An arc-shaped recess 811 is provided on the upper surface of the central support 81, which can be against the outer wall of the fixed terminal 6. When the central support 81 (riveting block 8) rotates with the handle, the arc-shaped recess 811 rotates synchronously along the outer wall of the fixed terminal 6.
[0047] Further, such as Figure 2 , 3 As shown, a slide groove 35 is provided between the inner side of the central slot 31 and the inner wall of the handle front shell 3, for the flange 61 on the outer wall of the fixed terminal 6 to slide in. A semicircular arc surface 311 matching the arc recess 811 is provided on the inner wall of the central slot 31, for the fixed terminal 6 to pass through. A protrusion 83 is provided on the riveting block 8, which can be fitted into the groove 33 provided on the handle front shell 3 for positioning. A locking hole 34 is provided on the handle front shell 3, and the riveting block 8 is fixed to the locking hole 34 by a fixing screw 9. As shown in FIG. Fig. 9As shown, after being threadedly connected and fixed with the handle front shell 3 , the back of the riveting block 8 is supported on the supporting stop 41 provided on the inner wall of the handle rear shell 4 .
[0048] The assembly process of the utility model:
[0049] 1. During assembly, after fixing the two fixed terminals 6 in the movable grooves 21 at both ends of the connecting portion 2, the plastic rotating ring 5 is inserted into the movable groove 21 to form an assembly.
[0050] 2. Insert the components assembled in the previous step into the corresponding slide grooves 35 of the handle front shell 3 in the correct direction, position and fix them left and right, then press the rivet block 8 into the corresponding slots (center slot 31 and side slot 32) of the handle front shell 3, and use fixing screws 9 to fix the rivet block 8 and the handle front shell 3. Use the side support 82 to press the boss 52 of the plastic rotating ring 5 to prevent the components assembled in the previous step from moving up and down.
[0051] 3. Buckle the handle rear shell 4 into the handle front shell 3 and fix it with screws. At the same time, the support stop 41 presses the riveting block 8 to increase the downward force of the block.
[0052] 4. Under the snapping force of the handle front shell 3 and the rivet block 8, the up, down, left and right directions of the plastic rotating ring 5 are fixed and can only rotate. Due to the plastic deformation of the plastic rotating ring 5 itself, the plastic rotating ring 5 can cooperate with the arc surface in the movable groove 21 when it rotates to a specific angle (0°, 45°, 90°), thereby eliminating the instability of the handle angle caused by shaking during use.
[0053] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
