[0030] The utility model provides a kind of arc adjusting mechanism, Figures 1 to 5 To provide the specific embodiment of arc adjusting mechanism of the utility model.

[0031] Refer to Figures 1 to 5 The arc adjusting mechanism 20, including first seat body 1, second seat body 2, locking piece 3, unlocking piece 4 and safety lock piece 5, first seat body 1 with second seat body 2, locking piece 3, unlocking piece 4 and safety lock piece 5 are movably connected, one end of locking piece 3 is in abutment with second seat body 2 to lock first seat body 1 and second seat body 2, unlocking piece 4 is used to move towards locking piece 3 to push locking piece 3 away from second seat body 2;

[0032] Safety lock piece 5 is arranged on first seat body 1 and has first position for being in abutment with unlocking piece 4 to resist the movement of unlocking piece 4 and second position for being separated from unlocking piece 4 to avoid unlocking piece 4.

[0033] In the embodiment, by moving safety lock piece 5 to first position, safety lock piece 5 resists the movement of unlocking piece 4 towards locking piece 3, that is, safety locking can be completed, by moving safety lock piece 5 to second position, safety lock piece 5 avoids unlocking piece 4, that is, safety unlocking can be completed, simple operation, high practicability.

[0034] Further, the safety lock 5 comprises a push button 51 arranged on the outer surface of the first seat body 1 and a clamping block 52 arranged in the first seat body 1 and connected with the push button 51. When the safety lock 5 is in the first position, the clamping block 52 abuts against the unlocking member 4. In the embodiment, the abutment between the clamping block 52 and the unlocking member 4 ensures that the unlocking member 4 cannot be moved when the safety lock 5 is in the first position, thereby preventing the occurrence of operation errors or accidental unlocking and ensuring the stability and safety during splicing.

[0035] Further, the unlocking member 4 is arranged through the first seat body 1, and the unlocking member 4 is provided with a avoiding slot 41 for the clamping block 52 to enter. When the safety lock 5 is in the second position, the position of the clamping block 52 corresponds to the position of the avoiding slot 41. In the embodiment, the cooperation between the avoiding slot 41 and the clamping block 52 ensures that the clamping block 52 can accurately enter the avoiding slot 41 when the safety lock 5 is in the second position, and the unlocking member 4 can be smoothly moved, thereby releasing the locking of the unlocking member 4 and facilitating the operation. Specifically, the outer surface of the first seat body 1 is provided with a limiting slot, and the push button 51 is arranged in the limiting slot.

In the embodiment, the positioning tooth 31 arranged on the locking member 3 cooperates with the tooth groove 21 on the second seat body 2 to achieve accurate positioning, ensuring that the first seat body 1 and the second seat body 2 always maintain the correct relative position in the locked state. This cooperation between the tooth groove 21 and the positioning tooth 31 effectively avoids displacement caused by external force or vibration, thereby enhancing the stability and safety of the whole.

[0038] Further, the locking piece 3 is provided with a first elastic piece 32 between the end away from the second seat body 2 and the first seat body 1, and the two ends of the first elastic piece 32 are respectively in abutment with the locking piece 3 and the first seat body 1. In the embodiment, after the unlocking piece 4 is pushed or pressed to push the locking piece 3 to move away from the second seat body 2 to unlock and adjust the first seat body 1 and the second seat body 2, the unlocking piece 4 is released, the locking piece 3 can be moved to abut against the second seat body 2 under the elastic force of the first elastic piece 32, and the first seat body 1 and the second seat body 2 are relocked. It should be noted that the first elastic piece 32 can be a spring, can be rubber, and can also be a material with deformation ability such as silica gel, which is not limited here.

[0039] Further, the unlocking piece 4 is provided with a second elastic piece 43 between the end close to the locking piece 3 and the first seat body 1, and the two ends of the second elastic piece 43 are respectively in abutment with the unlocking piece 4 and the first seat body 1. In the embodiment, after the unlocking piece 4 is pushed or pressed to unlock and adjust the first seat body 1 and the second seat body 2, the unlocking piece 4 is released, and the unlocking piece 4 can be automatically reset by the elastic force of the second elastic piece 43, so that the locking piece 3 can be moved to abut against the second seat body 2 under the elastic force of the first elastic piece 32, and the first seat body 1 and the second seat body 2 are relocked. It should be noted that the second elastic piece 43 can be a spring, can be rubber, and can also be a material with deformation ability such as silica gel, which is not limited here.

[0040] Further, the first seat body 1 is sleeved on the second seat body 2, and the second seat body 2 is provided with a scale mark. In the embodiment, the first seat body 1 can slide on the second seat body 2, and can be conveniently and accurately adjusted and positioned in cooperation with the scale mark. The user can accurately adjust the position of the first seat body 1 according to the indication of the scale mark, so as to ensure that the arc-shaped screen can be set to a suitable angle as required, and the convenience and accuracy of use are improved.

[0041] The utility model also proposes a display screen 10, the display screen 10 includes the arc adjusting mechanism 20, the specific structure of arc adjusting mechanism 20 refers to the above embodiment, because the display screen 10 that the utility model proposes includes all the schemes of all the embodiments of arc adjusting mechanism 20, therefore, at least have the same technical effect with arc adjusting mechanism 20, this place does not elaborate one by one.

[0042] Further, the display screen 10 further comprises a display panel 30, which is respectively hinged with the first seat body 1 and the second seat body 2. In this embodiment, by hinging the display panel 30 with the first seat body 1 and the second seat body 2, the display panel 30 can be adjusted at different angles and directions. This design enables the user to adjust the angle of the display panel 30 as needed to obtain the best visual display effect, thereby improving the operability and user experience of the device.

[0043] The above is only an optional embodiment of the present application, and does not limit the patent range of the present application.
