Description

Technical Field

[0001] This application relates to the field of electronic device accessories technology, and in particular to a mobile phone stand with a knob adjustment. Background Technology

[0002] There is a phone holder on the market that opens and closes via a knob. The two sides of the holder are connected by a screw, and turning the knob controls the screw to open and close the clamping parts on both sides. When in use, the phone is placed inside the holder, and the knob is adjusted to secure the phone to the clamping parts. However, excessive force applied to the knob can cause the clamping parts to grip the phone too tightly, potentially damaging the phone or the clamping parts themselves, resulting in a poor user experience. Utility Model Content

[0003] This application provides a mobile phone holder with a knob adjustment mechanism to at least solve the technical problem in the related art of damaging the mobile phone when adjusting the knob with excessive force.

[0004] To achieve the above objectives, this utility model provides a knob-adjustable mobile phone holder, including a first clamping member and a second clamping member. The first clamping member and the second clamping member are connected by a screw drive. A knob connected to the screw drive is provided on the outside of the second clamping member. A thread that mates with the screw is provided inside the first clamping member. The knob drives the screw to rotate to control the opening and closing of the first clamping member and the second clamping member. A toothed groove distributed circumferentially is formed on the screw. A movable member that engages with the toothed groove is provided inside the second clamping member. The rotation of the screw drives the toothed groove to move the movable member.

[0005] In some embodiments, the movable member is provided with locking teeth protruding toward the tooth groove, the locking teeth engaging into the tooth groove.

[0006] In some embodiments, the second clamping member is provided with a rotating shaft, one end of the movable member is rotatably sleeved on the rotating shaft, and the other end extends toward the tooth groove to form the clamping tooth.

[0007] In some embodiments, the toothed groove opens toward the axial direction of the screw, a receiving groove is formed in the second clamping member, and the movable member is installed in the receiving groove and can move along the axial direction of the screw.

[0008] In some embodiments, the movable member is provided with a return spring on the side away from the retaining teeth, the return spring causing the movable member to tend to return to its original position after being moved by the retaining teeth.

[0009] In some embodiments, the knob has a ratchet tooth formed circumferentially along its inner edge, and the knob contains a transmission member that is connected to the screw drive. The transmission member is provided with a movable latching member that engages with the ratchet tooth, and the latching member has an inclined surface that engages with the ratchet tooth.

[0010] In some embodiments, the transmission member has a receiving space for accommodating the snap-fit ​​member, within which the snap-fit ​​member moves.

[0011] In some embodiments, the snap-fit ​​elements are arranged along the radial direction of the knob.

[0012] In some embodiments, the snap-fit ​​member is telescopically movable within the receiving space, and a spring is provided at the end away from the ratchet to abut the snap-fit ​​member against the ratchet.

[0013] In some embodiments, two locking members are provided inside the knob along the diametrical direction. The locking members respectively engage with the ratchet, and the two locking members are connected by the spring.

[0014] Based on the above, the beneficial effects of this utility model's technical solution compared to the prior art are:

[0015] 1. The knob is equipped with ratchet teeth and a retractable latching component that works with the ratchet teeth. Under normal conditions, the latching component is held in place by a spring in the groove of the ratchet teeth. When the knob is rotated after the phone has been clamped, the spring is compressed and the latching component disengages from the ratchet teeth. At this time, rotating the knob will not drive the screw to move, thus avoiding damage to the phone.

[0016] 2. A movable part that cooperates with the screw is provided in the second clamping part. The movable part and the screw form a "tooth-groove" structure. During use, the "tooth-groove" structure will provide damping during the rotation process to counteract excessive torque and prevent damage to the mobile phone. Attached Figure Description

[0029] This utility model provides a knob-adjustable mobile phone holder, including a first clamping member and a second clamping member. The first clamping member and the second clamping member are connected by a screw drive. A knob connected to the screw drive is provided on the outside of the second clamping member. A thread that mates with the screw is provided inside the first clamping member. The knob drives the screw to rotate to control the opening and closing of the first clamping member and the second clamping member. A toothed groove is formed on the screw in a circumferentially distributed manner. A movable member that engages with the toothed groove is provided inside the second clamping member. The rotation of the screw drives the toothed groove to move the movable member.

[0030] Implementation, for example Figures 1-5 As shown, a knob-adjustable mobile phone holder includes a first clamping member 1 and a second clamping member 2. The first clamping member 1 and the second clamping member 2 are connected by a screw 3. A knob 4 connected by the screw 3 is provided on the outside of the second clamping member 2. Rotating the knob 4 can control the horizontal opening and closing of the first clamping member 1 and the second clamping member 2 through the screw 3.

[0031] Furthermore, a ratchet 4.1 is formed circumferentially inside the knob 4. The knob 4 contains a transmission component 5 that is connected to the screw 3. The transmission component 5 has a accommodating space along its diameter, and two retractable latching components 6 are provided at both ends of the accommodating space, connected by a spring. Each latching component 6 has an inclined surface that engages with the ratchet 4.1. Under the action of the spring at the end away from the ratchet 4.1, the latching component 6 is pressed against the ratchet 4.1. The other end of the transmission component 5 is connected to the screw 3. The first clamping component 1 has a thread that engages with the screw 3. When the knob 4 is rotated, the latching component 6, under the action of the spring, abuts against the ratchet 4.1 inside the knob 4, causing the transmission component 5 to rotate together. The transmission component 5, through the screw 3, drives the first clamping component 1 to move. When the clamping is stable or the movement reaches the end point, continue to rotate the knob 4. At this time, the force applied to the knob 4 is greater than the force applied by the spring to the locking member 6. The locking member 6 is continuously compressed back into the accommodating space, and the knob 4 can no longer drive the transmission member 5 to move through the locking member 6.

[0032] Preferably, the snap-fit ​​component 6 can also be arranged along the radius of the knob 4.

[0033] Furthermore, the screw 3 has a toothed groove 3.1 formed at one end located inside the second clamping member 2. The toothed groove 3.1 is distributed along the circumference of the screw 3. The second clamping member 2 is provided with a movable member 7. The movable member 7 is provided with a locking tooth 7.1 protruding towards the toothed groove 3.1. The locking tooth 7.1 is engaged in the toothed groove 3.1.

[0034] Specifically, the second clamping member 2 has a rotating shaft inside. The movable member 7 is located on the lower side of the screw 3, with one end rotatably sleeved on the rotating shaft, and the other end extending towards the tooth groove 3.1 to form a retaining tooth 7.1. The retaining tooth 7.1 engages with the tooth groove 3.1. A return spring is provided on the side of the movable member 7 away from the retaining tooth. One end of the return spring abuts against the second clamping member 2, and the other end abuts against the movable member 7. Each time the tooth groove 3.1 rotates, it will cause the movable member 7 to rotate through the retaining tooth 7.1. The return spring gives the movable member 7 a tendency to return to its original position after rotation, so that the retaining tooth 7.1 can re-engage with the tooth groove 3.1. The cooperation between the movable member 7 and the tooth groove 3.1 can generate a damping sensation when the knob 4 is rotated, thereby counteracting excessive torque and preventing damage to the mobile phone.

[0035] Specifically, this application also provides another way in which the moving part 7 mates with the toothed groove 3.1, such as... Figure 6 , 7As shown, the second clamping member 2 has a receiving groove for mounting the movable member 7. The toothed groove 3.1 opens in the axial direction of the screw 3, allowing the movable member 7 to move axially within the receiving groove along the screw 3. A return spring is provided on the side of the movable member 7 away from the retaining tooth. One end of the return spring abuts against the receiving groove, and the other end abuts against the movable member 7. Each rotation of the toothed groove 3.1 will cause the movable member 7 to retract via the retaining tooth 7.1. The return spring gives the movable member 7 a tendency to return to its original position after movement, facilitating the re-engagement of the retaining tooth 7.1 with the toothed groove 3.1. The cooperation between the movable member 7 and the toothed groove 3.1 provides damping resistance when the knob 4 is rotated, thereby counteracting excessive torque and preventing damage to the phone.

[0037] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
