Description

Technical Field

[0001] This utility model belongs to the field of mobile phone holder technology, and in particular relates to a multi-directional adjustable mobile phone holder. Background Technology

[0002] Phone stands typically only hold a phone or phone case in place and support it at a fixed angle. However, as users increasingly demand more flexible placement of their phones, existing phone stands are no longer sufficient to meet their needs.

[0003] Chinese patent application No. 201711469659.1 discloses a rotatable mobile phone holder, including a base and a clamping body rotatably connected to the base via a rotation adjustment mechanism. The rotation adjustment mechanism is located at the axis of the clamping body and the base. The rotation adjustment mechanism includes a T-shaped rotating block, an adjusting nut, and a bearing. The clamping body has a T-shaped groove that matches the T-shaped rotating block. The T-shaped rotating block is installed in the T-shaped groove. The bearing is installed between the clamping body and the T-shaped rotating block. The base is fixedly connected to the T-shaped rotating block via the adjusting nut. One side of the bottom of the base has an arc-shaped structure, and the other side has a height adjustment mechanism. The adjusting nut and the T-shaped rotating block are threaded together.

[0004] In the above technical solution, the clamping body and the base are connected by a rotation adjustment mechanism and positioned by a positioning protrusion, so that the clamping body can rotate freely. This allows the phone to be suspended at any rotation angle without removing it, simply by changing the positioning protrusion. However, in the above technical solution, the adjusting nut and the T-shaped rotating block are only connected by a single thread. This makes it difficult for the adjusting nut to maintain the preload when subjected to the force of reverse unlocking. As a result, the adjusting nut may fall out of the T-shaped rotating block, affecting the overall use effect and stability of the structure, and the effect is not good. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a multi-directional adjustable mobile phone holder is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A multi-directional adjustable mobile phone holder includes a support frame and a rotating component rotatably connected to the support frame. The rotating component has two movable claws, and the distance between at least one of the movable claws and the rotating component is adjustable. The rotating component is connected to the support frame by a connecting screw. The connecting screw includes, along the axial direction, a small thread segment, a connecting segment, and a large thread segment with a thread helix angle greater than that of the small thread segment. One end of the support frame is sleeved on the connecting segment. The rotating component is threadedly connected to the small thread segment. The support component is sleeved on the connecting segment and a pre-tightening structure is provided between it and the rotating component. A loosening nut is threadedly connected to the large thread segment. When the loosening nut moves in the unlocking direction, it is axially displaced and separates from the support frame, forming a sliding space for the support frame to slide relative to the axis of the connecting segment.

[0008] When the loosening nut is reversed and moved away from the support frame, a sliding space is formed between the loosening nut and the support frame, allowing the support frame to slide. The pre-tightening structure causes the support frame to slide along the axial direction of the connecting section, thereby unlocking the end face between the support frame and the rotating part. If rotation continues, the head of the loosening nut abuts against the head of the connecting screw, thereby driving the entire rotating part to rotate, preventing the connecting screw from disengaging from the rotating part due to over-rotation by the user.

[0009] Preferably, one end of the support frame has a recess that opens toward the rotating component, the recess has a circular cross-sectional shape, and the rotating component has a protrusion that fits into the recess at the corresponding position, and the connecting screw passes through the axial position of the recess.

[0010] By interlocking the recesses and convex parts, the circumferential contact between the recesses and convex parts ensures their coaxiality and resists the bending moment generated when the rotating part clamps the mobile phone, thus ensuring the structural strength between the support frame and the rotating part.

[0011] Preferably, the pre-tightening structure includes at least one receiving cavity located at an eccentric position of the protrusion, a reset member located within the receiving cavity, and a limiting member located at the opening of the receiving cavity. The end of the limiting member away from the rotating member is an arc surface. The arc surface includes at least one arc-shaped surface arranged in the direction of relative rotation between the protrusion and the concave portion. The concave portion is provided with arc grooves arranged in an array corresponding to the position of the arc surface.

[0012] By continuously pushing the limiting component with the reset component, the arc-shaped surface of the limiting component is kept in constant contact with the concave arc groove. This ensures that when the nut is untied by reversing, the support component remains in close contact with the nut, thereby adjusting the distance between the rotating component and the support component. Furthermore, under the force of the reset component, a preload is always generated between the rotating component and the small threaded section, and between the nut and the small threaded section.

[0013] The reset component can be any existing component that can continuously apply a pushing force to the limiting component, such as a magnetic component with the same magnetic pole as the limiting component, a thrust spring, or an airbag filled with a medium such as air or water.

[0014] The head of the limiting member can be an arc-shaped surface in one direction along the direction of relative rotation between the convex and concave parts, or a spherical surface in all directions; the overall structure of the limiting member can be a pin with an arc surface or a spherical structure.

[0015] Preferably, when the protrusion causes the limiting member to rotate over the arc groove, the resetting member is subjected to an axial inward force from the limiting member; when the limiting member is opposite to the arc groove, the force of the resetting member causes the limiting member to be embedded in the arc groove.

[0016] By positioning the limiting component relative to the arc groove, the rotation direction of the rotating component can be determined, and rotation feedback can be provided to the user, making it easier for the user to control the rotation angle of the rotating component.

[0017] Preferably, an auxiliary positioning component is provided between the protrusion and the recess. The auxiliary positioning component includes a waist-shaped block on the protrusion and a waist-shaped hole on the recess. The circumferential surface of the waist-shaped block is a tapered surface with a taper. The tapered surface makes the waist-shaped block have a frustum-shaped structure that protrudes outward relative to the protrusion. The opening position of the waist-shaped hole does not intersect with the rotation path of the limiting component.

[0018] By interlocking the waist-shaped block with the waist-shaped hole, the circumferential surface of the waist-shaped block guides the rotation trajectory of the rotating component, allowing the waist-shaped block to engage with the waist-shaped hole at a preset position. This achieves precise positioning of the relative rotation between the rotating component and the support frame, ensuring the display angle of the mobile phone after it is clamped.

[0019] Among them, the waist-shaped hole can be a through hole or a blind hole whose own diameter matches the shape of the waist-shaped block.

[0020] Preferably, the circumferential sidewall at the opening of the waist-shaped hole is provided with a taper that matches the tapered surface, thereby further ensuring the positional accuracy of the waist-shaped block when it is wedged in.

[0021] When the waist-shaped hole is a through hole, the opening of the waist-shaped hole is a tapered flared segmented channel; when the waist-shaped hole is a blind hole, the waist-shaped hole is a waist-shaped groove, and its groove shape matches the waist-shaped block.

[0022] Preferably, at least one end of the rotating member is provided with a rack, and one of the movable claws is sleeved on the rack through a sliding cavity. A button is provided through the movable claw in the direction perpendicular to the length of the rack. A clearance slide is provided at the center of the rack for the button to pass through. One end of the button is located outside the movable claw, and the other end of the button passes through the clearance slide and is fixedly provided with an outward expansion. The outward expansion engages with the rack. An elastic element for resetting the button is provided between the button and the inner wall of the sliding cavity.

[0023] When the button is pressed, it separates the outward expansion from the rack, thereby unlocking the movable jaws and enabling rapid adjustment of the distance between the two movable jaws.

[0024] Preferably, the teeth of the rack face the same direction as the barbs of the movable claw, so that the button is located on the back of the movable claw, thereby avoiding obstruction of the movable claw's gripping of the mobile phone.

[0025] Preferably, the rotating component has a threaded hole at one end away from the rack, and a lead screw is threaded into the threaded hole. The other end of the lead screw extends away from the rotating component and has another movable pawl. The other end of the lead screw has a knob fixed coaxially with the lead screw. A limiting slide rod is provided between the other movable pawl and the rotating component and is embedded in the rotating component. The limiting slide rod is parallel to the axis of the lead screw.

[0026] The lead screw allows for fine-tuning of the other movable jaw, ensuring precise adjustment of the distance between the two jaws. This movable jaw controls the clamping force on the phone, maintaining stable clamping. Furthermore, the lead screw's self-locking property prevents the distance between the jaws from becoming uncontrolled, thus preventing the phone from coming loose.

[0027] Preferably, the support frame is provided with a fixing member at one end away from the connecting section. The fixing member is connected to the support frame via a pivot connector with adjustable axial spacing. The fixing member at one end away from the support frame is provided with an installation structure for connecting to the outer circular surface or plane of an object, thereby enabling the bracket to be adapted to different usage scenarios and expanding the applicability of the bracket.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] The device can stably clamp and fix different models of mobile phones by means of two adjustable movable claws. It also uses a differential thread structure formed by small and large thread segments. The distance between the support and the rotating part is controlled by the rotation of the loose nut. When the loose nut is unlocked, the thread helix angle of the small thread segment limits the loose nut to prevent it from falling off the connecting screw, thus ensuring the overall stability of the structure.

[0030] By using rotating and limiting components, the phone is clamped and fixed by two movable claws, allowing it to hover at different angles and provide rotational feedback to the user. This makes it easy for the user to control the rotation angle of the rotating components, thereby controlling the display angle of the phone. Attached Figure Description

[0041] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] like Figure 1-8 As shown, this embodiment discloses a multi-directional adjustable mobile phone holder, including a support frame 11 and a rotating component 15 rotatably connected to the support frame 11. The support frame 11 includes a rotating support portion 111 for connecting with the rotating component 15 and an extension portion 112 extending radially from the rotating support portion 111. The extension portion 112 consists of two symmetrically arranged rod-shaped structures. A fixing member 12 is provided between the two extension portions 112. The fixing member 12 is connected to the extension portion 112 via a pivot connector 14 with an adjustable axial spacing. The pivot connector 14 has the same structure as the prior art. When the pivot connector 14 is tightened, the extension portions 112 located on both sides can be brought closer to each other, thereby clamping the fixing member 12 and increasing the friction between the extension portion 112 and the fixing member 12 to achieve rotational fixation between the fixing member 12 and the extension portion 112.

[0044] The end of the fastener 12 away from the support frame 11 is provided with an installation structure 13 for connecting with the outer circular surface of the object. The installation structure 13 consists of an upper bearing 131 and a lower bearing 132 arranged symmetrically. After the upper bearing 131 and the lower bearing 132 are combined, a central through hole 133 is formed at the center position for the rod-shaped structure to pass through. Two first screw holes 134 are provided on both sides of the central through hole 133. The upper bearing 131 and the lower bearing 132 are locked by two fastening screws (not shown in the figure) arranged in the radial direction, thereby connecting the fastener 12 with the outer circular surface of the object.

[0045] The rotating component 15 has two movable claws at both ends along its length. The two movable claws include a first movable claw 16 and a second movable claw 17. The inner sides of the first movable claw 16 and the second movable claw 17 are provided with anti-slip pads 18. When the first movable claw 16 and the second movable claw 17 approach each other, they can clamp and fix the mobile phone by their barbs. After rotating the rotating component 15 relative to the support frame 11 by a certain angle, the mobile phone can be clamped and fixed at the angle preset by the user.

[0046] One end of the rotating component 15 is provided with a rack 19. The tooth surface of the rack 19 is in the same direction as the barb of the movable claw. The first movable claw 16 has a sliding cavity inside. The first movable claw 16 is sleeved on the rack 19 through the sliding cavity. A button 20 is provided through the first movable claw 16 perpendicular to the length direction of the rack 19. The center of the rack 19 is provided with a clearance slide 21 for the button 20 to pass through. The clearance slide 21 is a long strip-shaped opening structure. One end of the button 20 is located outside the first movable claw 16. The other end of the button 20 passes through the clearance slide 21 and is fixed with an expansion part 211. The expansion part 211 meshes with the rack 19. An elastic element for resetting the button 20 is provided between the button 20 and the inner wall of the sliding cavity. The elastic element is a first thrust spring 22.

[0047] When the user presses button 20, button 20 compresses the first thrust spring 22 and causes the outward expansion 211 to slide away from the rack 19. At this time, the first movable claw 16 is unlocked from the rack 19. While keeping button 20 pressed, the first movable claw 16 is pulled away along the length of the rack 19. Button 20 slides relative to the relief slide 21, thereby adjusting the distance between the first movable claw 16 and the rotating part 15.

[0048] The rotating part 15 has a threaded hole 26 at one end away from the rack 19. A lead screw 23 is threaded into the threaded hole 26. The other end of the lead screw 23 extends away from the rotating part 15 and is connected to a second movable pawl 17. The lead screw 23 and the second movable pawl 17 are rotated and supported by a bearing. The other end of the lead screw 23 has a knob 24 fixed coaxially with the lead screw 23. A limiting slide rod 25 is embedded in the rotating part 15 between the second movable pawl 17 and the rotating part 15. The limiting slide rod 25 is parallel to the axis of the lead screw 23.

[0049] When the knob 24 is rotated, the knob 24 drives the lead screw 23 to rotate. The lead screw 23 slides relative to the rotating part 15 through the outer circular thread, thereby adjusting the distance between the second movable pawl 17 and the rotating part 15.

[0050] The rotating component 15 is connected to the support frame 11 via a connecting screw 35. The connecting screw 35 includes, along the axial direction, a small thread section 351, a connecting section 352, and a large thread section 353 with a thread helix angle greater than that of the small thread section 351. One end of the support frame 11 is fitted onto the connecting section 352. The rotating component 15 is threaded onto the small thread section 351. A pre-tightening structure is provided between the support component fitted onto the connecting section 352 and the rotating component 15. The loosening nut 36 is threaded onto the large thread section 353. The tail of the loosening nut 36 is provided with a cap 37 directly opposite the head of the connecting screw 35. The cap 37 can seal and protect the head of the connecting screw 35. When the loosening nut 36 is in the unlocking direction, the loosening nut 36 shaft... After displacement, it separates from the support frame 11 and forms a sliding space 38 for the support frame 11 to slide relative to the axis of the connecting section 352. When the tightening nut 36 rotates to abut against the head of the connecting screw 35, it drives the entire rotating part 15 to rotate. This prevents the connecting screw 35 from disengaging from the rotating part 15 due to over-rotation by the user. Even if the rotating part 15 is held in place and the tightening nut 36 is continued to be tightened, the torque on the connecting screw 35 is less than the torque in the axial direction due to the thread helix angle of the small thread section 351. This causes the threads between the tightening nut 36 and the connecting screw 35 to self-lock, making it impossible to rotate the tightening nut 36 to unlock the connecting screw 35 from the rotating part 15.

[0051] One end of the support frame 11 has a recess 31 that opens toward the rotating member 15. The cross-sectional shape of the recess 31 is circular. The rotating member 15 has a protrusion 27 that fits into the recess 31. The connecting screw 35 passes through the axial position of the recess 31.

[0052] The pre-tightening structure includes four receiving cavities 28 located at eccentric positions on the protrusion 27, a reset member located within the receiving cavity 28, and a limiting member located at the opening of the receiving cavity 28. The limiting member is located in at least one of the receiving cavities 28. The limiting member is a limiting ball 30 with a spherical surface, which makes the end away from the rotating member 15 an arc surface. The concave portion 31 is provided with arc grooves corresponding to the position of the spherical surface. The arc grooves are spherical grooves 32. The receiving cavities 28 and the spherical grooves 32 are arranged in a ring array on the outer side of the circumference of the connecting screw 35. The reset member is a second thrust spring 29.

[0053] When the protrusion 27 causes the limiting ball 30 to rotate over the spherical groove 32, the second thrust spring 29 exerts an inward axial force on the limiting ball 30; when the limiting ball 30 is opposite to the spherical groove 32, the elastic force of the second thrust spring 29 causes the limiting ball 30 to be embedded in the spherical groove 32.

[0054] An auxiliary positioning component is also provided between the protrusion 27 and the recess 31. The auxiliary positioning component includes a waist-shaped block 33 provided on the protrusion 27 and a waist-shaped hole 34 provided on the recess 31. The circumferential surface of the waist-shaped block 33 is a tapered surface with a taper. The tapered surface makes the waist-shaped block have a frustum-shaped structure that protrudes outward relative to the protrusion 27. The circumferential sidewall at the opening of the waist-shaped hole is provided with a taper that fits the tapered surface. The opening position of the waist-shaped hole 34 does not intersect with the revolution path of the limiting ball 30.

[0055] Example 2

[0056] The difference between this embodiment and Embodiment 1 is that: Figure 9 As shown, the mounting structure 13 is a fixing plate 135. The fixing plate 135 has a second screw hole 136 for fastening screws (not shown in the figure) to pass through. The fixing plate 135 is locked and fixed to the plane of the object by fastening screws (not shown in the figure), thereby connecting the fixing member 12 to the plane of the object.
