[0021] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0022] like Figure 1-7 As shown,

[0023] A locking structure with adjustable angle comprises a tray 1, a connecting base 2, a positioning block 3, a fixing rod 4 and a fastening cover 5; a connecting block 6 is arranged on the tray 1, and the tray 1 is rotatably connected to the connecting base 2 through the connecting block 6; a positioning block 3 is arranged inside the connecting base 2, a limiting slot 7 is arranged on the positioning block 3, a limiting rib 8 corresponding to the limiting slot 7 is arranged on the connecting block 6, and a fixing rod 4 is connected to the end of the positioning block 3 away from the limiting slot 7, and the fixing rod 4 is threadedly connected to the fastening cover 5; in this embodiment, when the limiting rib 8 is in contact with the limiting slot 7, the tray 1 can be locked (cannot be rotated along the connecting base 2), and when the limiting slot 7 leaves the limiting rib 8, the locking can be released. After the locking is released, the tray 1 can be rotated along the connecting base 2 to adjust the angle. The process does not use the friction between the components for fixing. No matter how long it is used, the positioning will not loosen, making the fixing angle more reliable.

[0024] As a preferred embodiment; the connecting block 6 is rotatably connected to the connecting base 2 via a rotating shaft 9; it can be understood that the rotating shaft 9 is a fixed rotating shaft, which can effectively connect the tray 1 and the connecting base 2 together without separation, and can also realize its rotation.

[0025] As a preferred embodiment; both ends of the outer edge of the positioning block 3 are provided with adjustment grooves 10, and the interior of the connecting base 2 is provided with a buckle 11 corresponding to the adjustment groove 10; by providing the adjustment groove 10 and the buckle 11, during the up and down movement of the positioning block 3, the buckle 11 moves relatively in the adjustment groove 10, and there is adjustment space in the adjustment groove 10, and when the positioning block 3 moves down to the maximum distance (the downward movement process is the unlocking process), the buckle 11 and the adjustment groove 10 will be clamped, which has a limiting effect.

[0026] As a preferred embodiment; the fixing rod 4 is provided with an external thread 12 at one end close to the positioning block 3, and the inner wall of the fastening cover 5 is provided with an internal thread, and the fixing rod 4 is threadedly connected to the fastening cover 5; by adopting the threaded connection, after rotating the fastening cover 5, the positioning block 3 can move up and down relatively to perform locking or unlocking operations.

[0027] As a preferred embodiment, a soft rubber pad 13 is bonded to the end surface of the tray 1 ; by providing the soft rubber pad 13 , a mobile phone or tablet can be prevented from being damaged when placed on the tray 1 .

[0028] The working principle of the utility model is as follows: when the structure is in a locked state, the fastening cover 5 can be rotated counterclockwise, at which time the fastening cover 5 moves upward relatively, while the fixing rod 4 and the positioning block 3 move downward relatively, so that the limiting rib 8 relatively leaves the limiting slot 7. At this time, the angle of the tray 1 can be adjusted. After the angle is determined, the fastening cover 5 can be rotated clockwise, and the process is opposite to the above-mentioned unlocking process, so that the tray 1 is re-locked and fixed.

[0029] It should be pointed out that the main problems in the prior art are: the adjustable angle structure design of the bracket is usually fixed by the friction between the parts. After a long time of use, the parts will wear each other, resulting in loose positioning and unreliable fixed angle;

[0030] Therefore, through the improvement of the present application, the angle adjustment of the bracket is made more reliable, and the positioning will not become loose no matter how long it is used, and the quality and effect of use are greatly improved.

[0031] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
