[0012] Beneficial Effects

[0013] In the prior art, a tablet computer protective case is a protective device, which is mainly used to protect the tablet computer from damage caused by accidental impact, scratches, falls, etc. The existing tablet computer mainly limits the bottom of the tablet computer by setting a limiting groove on the surface of the folding protective case, and adjusts the angle of the tablet computer by multiple grooves. However, when the tablet computer is accidentally touched, the computer is easy to disengage from the groove, causing the tablet computer to fall and cause damage to the tablet computer. To address this problem, the utility model adopts an angle adjustment mechanism. When the angle of the bracket needs to be adjusted, the rotating handle drives the micro worm to rotate, and the micro worm drives the micro worm wheel to rotate, thereby driving the bracket to rotate, and when the helix lead angle of the worm is less than the equivalent friction angle between the meshing teeth of the worm and the worm wheel, the worm gear structure has self-locking properties, that is, the worm can drive the worm wheel to rotate, but the worm wheel cannot drive the worm to rotate, thereby improving the stability of the bracket and preventing the tablet computer from being accidentally touched and falling.

A U-shaped groove is provided on the back of the protective case body 1, and a bracket 3 is rotatably connected to the top of the U-shaped groove, and the bracket 3 is in a U shape. A rubber sleeve is bonded to the bottom of the bracket 3, and the rubber sleeve increases the friction between the bottom of the bracket 3 and the desktop, further improving the stability of the bracket 3. A placement cavity is provided on one side of the bracket 3, and a micro worm gear 4 is provided inside the placement cavity, and the micro worm gear 4 is fixedly connected to one side of the bracket 3. A micro worm 5 is meshed on the surface of the micro worm gear 4, and both ends of the micro worm gear 5 are rotatably connected to the inner wall of the placement cavity, and a rotary handle 6 is fixed on the side of the micro worm gear 5, and an anti-skid pattern is provided on the surface of the rotary handle 6, and the anti-skid pattern increases the friction between the rotary handle 6 and the user's fingers, so that the user can rotate the rotary handle 6 conveniently. The helix angle of the micro worm 5 is smaller than the equivalent friction angle between the meshing teeth of the micro worm 5 and the micro worm wheel 4 .

[0025] The surface array of the protective shell body 1 is provided with a limit slot 103, and the limit slot 103 is internally slidably connected to the limit block 7, and a card slot is provided at the bottom of the limit block 7, and a limit spring 8 is fixed between the top of the limit block 7 and the inner wall of the protective shell body 1. The existing tablet computer protective shell is usually only suitable for tablet computers of fixed size. When replacing a tablet computer, the corresponding protective shell also needs to be replaced, which increases the replacement cost. In view of such problems, the utility model adopts a limit mechanism. When the size of the tablet changes, the limit block 7 is moved so that the bottom card slot is against the upper and lower ends of the tablet computer, and it is limited under the elastic force of the limit slot 103, which improves the stability of the tablet computer, and is suitable for tablet computers of different sizes, reducing the use cost. The limit slot 103 is set as a T-slot, which improves the stability of the limit block 7.

[0026] An array of heat dissipation holes 101 is provided on the back of the protective shell body 1. Existing tablet computers will generate a large amount of heat after long-term use, causing the surface of the tablet computer to become hot. Under the protection of the protective shell, the heat cannot be dissipated in time, thereby reducing the service life of the tablet computer. To address this problem, the utility model provides an array of heat dissipation holes 101 on the back of the protective shell body 1.

[0027] In the prior art, a tablet computer protective case is a protective device, which is mainly used to protect the tablet computer from damage caused by accidental impact, scratches, and falls. Existing tablet computers mainly limit the bottom of the tablet computer by setting limiting grooves on the surface of the folding protective case, and adjust the angle of the tablet computer by multiple grooves. However, when the tablet computer is accidentally touched, the computer is easy to disengage from the grooves, causing the tablet computer to fall and cause damage to the tablet computer. To address this problem, the utility model adopts an angle adjustment mechanism. When the angle of the bracket 3 needs to be adjusted, the rotating handle 6 is rotated to drive the micro worm 5 to rotate, and the micro worm 5 drives the micro worm wheel 4 to rotate, thereby driving the bracket 3 to rotate, and when the helix lead angle of the worm is less than the equivalent friction angle between the meshing teeth of the worm and the worm wheel, the worm gear structure has self-locking properties, that is, the worm can drive the worm wheel to rotate, but the worm wheel cannot drive the worm to rotate, thereby improving the stability of the bracket 3 and preventing the tablet computer from being accidentally touched and falling.

[0028] The working principle of the utility model is as follows: the limit block 7 is moved so that the bottom end slot thereof abuts against the upper and lower ends of the tablet computer, and is limited under the elastic force of the limit slide groove 103, and the rotation handle 6 drives the micro worm 5 to rotate, and the micro worm 5 drives the micro worm wheel 4 to rotate, thereby driving the bracket 3 to rotate, and the rubber sleeve increases the friction between the bottom of the bracket 3 and the desktop.
