Description

Technical Field

[0001] The utility model relates to a placing rack, in particular to a telescopic placing rack capable of rotating, tightening and positioning. Background Art

[0002] For example, the Chinese Taiwan Patent Announcement No. M645380 discloses a mobile phone holder (MOBILE PHONEHOLDER), which mainly includes a frame, a plurality of clamping members, and an elastic member, etc. The clamping members are arranged around the frame, the clamping members are slidably arranged in the frame, and two of the clamping members are arranged on the ends of the clamping members to clamp the mobile phone on the frame, the elastic member is arranged in the frame, and the two ends of the elastic member are respectively abutted against the clamping member and the frame, so that the user can pull the clamping member upward to adjust the distance between the upper and lower clamping members, so that when the clamping member is pulled upward, the clamping member will compress the elastic member, and when the clamping member is released, the elastic member will drive the clamping member to reset downward, so that the mobile phone holder can clamp mobile phones of different sizes.

[0003] However, the aforementioned mobile phone holder is not provided with any locking structure, so that the mobile phone is only clamped on the holder by the elastic force of the elastic member. Thus, when the motorcycle travels on a rough road, the vibration feedback from the ground makes the mobile phone easily fall off the holder, causing it to fall and be damaged.

[0004] Although the aforementioned mobile phone has a plurality of clamping parts disposed around the frame to provide a function of surrounding the mobile phone, too many clamping parts hinder the user experience of taking the mobile phone on the frame. Utility Model Content

[0051] The following detailed description of the exemplary embodiments of the present application is made with reference to the accompanying drawings, and it is not intended to limit the technical principles of the present application to the specific disclosed embodiments, and the scope of the present application is limited only by the scope of the patent application, covering substitutions, modifications and equivalents. In addition, in order to improve readability, some of the components are omitted in some illustrations, or are depicted using imaginary lines or other methods.

[0052] See also Figures 1 to 8 As shown, the present application provides a telescopic placement rack 100 for rotational clamping and positioning, which can be installed on a vehicle and provided for clamping and positioning a mobile device 1. The vehicle is, for example, a motorcycle, and the mobile device 1 is, for example, a smart phone. The telescopic placement rack 100 for rotational clamping and positioning includes a main body 10, an actuator 20, an elastic member 30, a clamping member 40 and a clamping member 50.

[0053] The body 10 has a first axis 11 and a second axis 12. The first axis 11 is the central axis of the body 10. The first axis 11 and the second axis 12 are parallel and non-coaxial. The body 10 is provided with a circular eccentric chamber 13 along the second axis 12. The second axis 12 passes through the center of the eccentric chamber 13. Figure 4 As shown, one side of the eccentric chamber 13 is connected to an arc-shaped limit groove 14, and the limit groove 14 has a first positioning portion 141 with a continuous concave-convex shape. In the embodiment of the present application, the body 10 includes a front cover 10A and a rear seat 10B that cover each other, and the front cover 10A and the rear seat 10B are fixed to each other by screws 15. Figure 3 As shown, two slide grooves 10C are provided on both sides between the front cover 10A and the rear seat 10B. The eccentric chamber 13 is provided on the rear seat 10B, and a polygonal groove 131 is recessed on the second axis 12 of the eccentric chamber 13 .

[0054] The present application further includes a shaft member 60, which is arranged on the body 10 in a non-rotatable manner. In the embodiment of the present application, the shaft member 60 has a polygonal plate 61, and a shaft column 62 protrudes on one side of the polygonal plate 61. The polygonal plate 61 is accommodated in the polygonal groove 131 and cannot rotate relative to it. The shaft column 62 is erected in the eccentric chamber 13 and extends along the second axis 12. The polygonal plate 61 of the shaft column 62 is provided with a protruding column 611 on one side. In addition, the polygonal plate 61 has a bolt 63 on the other side that extends through the polygonal groove 131 and is partially exposed to the rear seat 10B. Different from the shaft column 62, the shaft member 60 is provided with a ball head 64, and the ball head 64 has a screw hole 641 that is screwed with the bolt 63, so that the ball head 64 is located on the back of the rear seat 10B, so that the telescopic placement rack 100 can be rotated at multiple angles to be installed on the fixing mechanism (not shown) of the vehicle.

[0055] The actuator 20 is rotatably disposed in the eccentric chamber 13. The actuator 20 is provided with a ratchet 21 and a square hole 22 disposed at the central position and penetrating. In the embodiment of the present application, the shaft column 62 is rotatably sleeved with a gear member 23, and the gear member 23 is coaxially connected with the actuator 20. The gear member 23 has a transmission tooth 231, an axial hole 232 and a square column 233. The square column 233 of the gear member 23 is engaged with the square hole 22 of the actuator 20 and will not rotate with each other. The axial hole 232 of the gear member 23 is sleeved on the shaft column 62, so that the actuator 20 and the gear member 23 can synchronously generate a rotational motion relative to the shaft member 60.

[0056] In addition, if Figure 4 As shown, the side of the actuating member 20 facing the eccentric chamber 13 has a hook groove 20 a.

[0057] The elastic member 30 is located in the eccentric chamber 13, and the two ends of the elastic member 30 are respectively connected to the body 10 and the actuating member 20. In the embodiment of the present application, the elastic member 30 is a vortex spring, and the elastic member 30 has a first hook end 31 fixed to the convex column 611 of the shaft member 60, and the elastic member 30 has a second hook end 32 fixed to the hook groove 20a, so that the elastic member 30 is connected between the shaft member 60 and the actuating member 20. When the actuating member 20 rotates in the forward or reverse direction, the elastic member 30 will shrink or expand, thereby generating a restoring force.

[0058] The number of the clamping members 40 in the embodiment of the present application is two. The two clamping members 40 are respectively slidably disposed on both sides of the body 10, and can generate an opening and closing action relative to the body 10. In other embodiments of the present application, there can also be only one clamping member 40. For example, the body 10 has a fixing member and a clamping member 40 slidably disposed on the body 10, and the clamping member 40 can generate an opening and closing action with the fixing member.

[0059] In the embodiment of the present application, each clamping member 40 has a sliding portion 41 extending through the slide groove 10C of the body 10, so that the two clamping members 40 are stacked in the slide groove 10C and are respectively slidably disposed on both sides of the body 10, and each clamping member 40 is respectively connected to the actuator 20. Each sliding portion 41 has a long hole 42 in the shape of a closed hole, and a tooth row 421 is provided on one side of the inner edge of the long hole 42. The transmission teeth 231 of the gear member 23 are located in the two long holes 42 and mesh with the two tooth rows 421, so that the clamping member 40 is transmission-connected to the actuator 20 through the gear member 23.

[0060] In this way, Figure 6 And cooperate Figure 2 As shown in FIG. 1 , when the two clamping members 40 are stretched toward the outside of the body 10 by an external force, the gear row 421 drives the gear member 23 to rotate and drives the actuating member 20 at the same time, so that the actuating member 20 rotates and displaces along the second axis 12, and the elastic member 30 can generate a restoring force. When the external force is removed (i.e., the two clamping members 40 are no longer stretched), the elastic member 30 reverses the actuating member 20 through the restoring force, so that the two sliding parts 41 extend into the body 10, and the two clamping members 40 are condensed, so as to achieve the purpose of clamping the action device 1, as shown in FIG. Figure 7 .

[0061] The clamping member 50 is assembled to the body 10 along the first axis 11, and the clamping member 50 can rotate relative to the body 10 at a first position and a second position. In the embodiment of the present application, the clamping member 50 has a ring portion 51 sleeved on the periphery of the rear seat 10B of the body 10, and the clamping member 50 is located at the back side of the two clamping members 40. Both sides of the ring portion 51 each have an operating protrusion 511 for the user to drive and rotate.

[0062] The clamping member 50 has a pawl 52, which is disposed inside the ring portion 51 and extends toward the first axis 11. The pawl 52 is received in the limiting groove 14 of the body 10. When the clamping member 50 rotates relative to the body 10, the pawl 52 moves between the two ends of the limiting groove 14. Figure 2 and Figure 4 As shown, the pawl 52 has a tooth surface 521 meshing with the ratchet teeth 21 and a second positioning portion 522 opposite to the tooth surface 521 facing the actuator 20. The second positioning portion 522 is a continuous concave-convex shape and cooperates with the first positioning portion 141, and the two can be positioned by friction, which has the effect of keeping the clamping member 50 in the first position or the second position. In addition, there is a cutout 523 between the second positioning portion 522 and the tooth surface 521, and the cutout 523 makes the second positioning portion 522 elastic and easy to press against the first positioning portion 141.

[0063] Thus, in the first position, the pawl 52 is engaged with the ratchet 21, so that the pressing member 50 presses the actuating member 20, so that the actuating member 20 cannot rotate, and further the two clamping members 40 cannot slide relative to the body 10 to form a positioning state, such as Figure 8 In the second position, the clamping member 50 deviates from the actuating member 20, that is, the pawl 52 is not engaged with the ratchet 21 and deviates, so that the actuating member 20 can rotate, and further the two clamping members 40 can slide relative to the body 10 to form a free state, such as Figure 7 .

[0064] As described above, during actual operation, the present application is installed on a vehicle via the ball head 64. At this time, the clamping member 50 is located in the second position. The user pulls one of the clamping members 40 with one hand to slide it outward from the main body 10, and the other clamping member 40 also slides in conjunction with it, so that the mobile device 1 can be placed between the two clamping members 40 with one hand, and then the clamping member 40 is released, and the actuating member 20 is reversed through the elastic member 30, thereby driving the gear member 23 to rotate in the opposite direction and driving the sliding portions 41 of the two clamping members 40 to synchronously retract into the main body 10 until the two clamping members 40 are against both sides of the mobile device 1 to form a temporary positioning.

[0065] Next, the user rotates the clamping member 50 to the first position, so that the pawl 52 of the clamping member 50 engages with the ratchet teeth 21 of the actuating member 20 to suppress the actuating member 20 so that it cannot rotate, thereby preventing the two clamping members 40 from being pulled apart from the body 10, preventing the mobile device 1 from falling off from the body 10, and providing a tight clamping effect.

[0066] In addition, after the pawl 52 is engaged with the ratchet teeth 21, the user can rotate the tightening member 50 again to increase the rotation angle of the pawl 52 of the tightening member 50 relative to the actuator 20, so as to facilitate the pawl 52 to engage with more teeth of the ratchet teeth 21, thereby improving the self-locking effect and avoiding unnecessary loosening or disengagement caused by external forces.

[0067] See also Fig. 9 , which is another embodiment of the present application. The difference from the above embodiment is that the above elastic member 30 is not used in this embodiment, that is, the two clamping members 40 are directly pushed back and shrunk relative to the body 10, rather than relying on the restoring force of the elastic member 30. However, by rotating the clamping member 50 between the first position and the second position, the clamping member 50 can press the actuating member 20 in the first position, so that the two clamping members 40 cannot slide relative to the body 10 and form a fixed state. In the second position, the clamping member 50 deviates from the actuating member 20, so that the two clamping members 40 can slide relative to the body 10 and form a free state. In this way, the purpose and effect of firmly clamping the mobile device 1 are also achieved.

[0068] The above embodiments are only used to illustrate the present application, and are not used to limit the scope of the present application. Any modifications or changes that do not violate the spirit of the present application are within the scope of protection intended by the present application.
