The left and right sides of the case body are provided with mounting grooves, and each support rod corresponds to one mounting groove. A retaining ring is provided in the mounting groove. The side of the support rod near the case body is provided with a receiving groove. The inner circumferential surface of the receiving groove is provided with multiple toothed grooves. The retaining ring is provided with two symmetrical through grooves, which make the retaining ring form an elastically deformable arc plate. The outer circumferential surface of the two arc plates is provided with retaining teeth. The two support rods are rotatably connected to the left and right sides of the case body, respectively. The retaining ring is located in the receiving groove, and the retaining teeth are engaged in the toothed grooves.

[0006] Furthermore, connectors are embedded in the left and right ends of the sheath body, the retaining ring is fixedly connected to the connectors, and the support rod is rotatably connected to the retaining ring.

[0007] Furthermore, the upper part of the connector is provided with a connecting part, the connecting part is provided with a square shaft hole, the retaining ring is provided with a square shaft portion adapted to the square shaft hole, the retaining ring is provided with a shaft hole penetrating the square shaft portion, a rotating shaft is fixedly provided in the receiving groove, the rotating shaft passes through the shaft hole, the connector is provided with a through hole communicating with the shaft hole, the rotating shaft is provided with a threaded hole, the inner diameter of the through hole is larger than the inner diameter of the threaded hole, the connector and the rotating shaft are connected by a screw, the screw passes through the through hole and is threadedly connected to the threaded hole.

[0008] Furthermore, the inlet of the through hole is provided with multiple anti-loosening protrusions.

[0009] Furthermore, the left and right ends of the sheath body are provided with inlay grooves and receiving holes and mounting openings that communicate with the inlay grooves. The receiving holes communicate with the mounting grooves. The receiving holes and mounting openings are located on both sides of the inlay grooves. The height of the mounting openings is less than the height of the inlay grooves. The connectors are embedded in the inlay grooves, and the connecting parts are located in the receiving holes.

[0010] Furthermore, the left and right rear sides of the sheath body are provided with relief grooves, which correspond to the middle of the support rod.

[0011] Furthermore, the left and right sides of the sheath body are provided with positioning recesses, and the two support rods are provided with positioning protrusions near the bottom of the side of the sheath body, and the positioning protrusions are located in the positioning recesses.

[0012] As described above, compared with the prior art, this utility model has the following advantages: When a tablet computer is placed inside the protective case, and the tablet needs to be tilted for viewing, the two support rods can be rotated open to support the protective case. The opening angle of the two support rods can be adjusted. During the rotation of the support rods, the arc-shaped piece deforms. Each time the support rod rotates by an angle, the arc-shaped piece deforms once, and the locking teeth on the arc-shaped piece engage in different grooves. This utility model can achieve different opening angles for the two support rods, meeting the multi-angle support needs of the protective case. Attached Figure Description

The left and right sides of the case body 1 are provided with mounting grooves 11, and each support rod 2 corresponds to one mounting groove 11. A retaining ring 3 is provided within each mounting groove 11. The support rod 2 has a receiving groove 21 near the side of the case body 1. The inner circumferential surface of the receiving groove 21 has multiple toothed grooves 22. The retaining ring 3 has two symmetrical through grooves 31, which allow the retaining ring 3 to form an elastically deformable arcuate piece 32. The outer circumferential surface of each of the two arcuate pieces 32 has retaining teeth 33. The two support rods 2 are rotatably connected to the left and right sides of the case body 1, respectively. The retaining ring 3 is located within the receiving groove 21, and the retaining teeth 33 are engaged within the toothed grooves 22.

[0022] Reference Figures 1 to 5 The sheath body 1 has connectors 4 embedded in its left and right ends. The retaining ring 3 is fixedly connected to the connector 4, and the support rod 2 is rotatably connected to the retaining ring 3. The support rod 2, retaining ring 3, and connector 4 are all made of plastic. The upper part of the connector 4 has a connecting portion 41 with a square shaft hole 42. The retaining ring 3 has a square shaft portion 34 that matches the square shaft hole 42, and a shaft hole 35 that passes through the square shaft portion 34. A rotating shaft 23 is fixedly installed in the receiving groove 21, and the rotating shaft 23 passes through the shaft hole 35. The connector 4 has a through hole 43 communicating with the shaft hole 35, and the rotating shaft 23 has a threaded hole 24. The inner diameter of the through hole 43 is larger than the inner diameter of the threaded hole 34. The connector 4 and the rotating shaft 23 are connected by screws, which pass through the through hole 43 and are threaded into the threaded hole 24. The inlet of the through hole 43 is provided with multiple anti-loosening protrusions 44. When the screw is locked with the threaded hole 24, the multiple anti-loosening protrusions 44 can prevent the screw head from loosening and slipping. The cooperation between the square shaft portion 34 and the square shaft hole 42 fixes the retaining ring 3 relative to the connecting portion 41, and the retaining ring 3 cannot rotate relative to the connecting portion 41. The rotating shaft 23 can rotate around the shaft hole 35, so that the support rod 2 can rotate relative to the retaining ring 3.

[0023] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 The left and right rear sides of the sheath body 1 are provided with relief grooves 12, which correspond to the middle of the support rod 2. The relief grooves 12 provide space for people's fingers to place, making it convenient to open the support rod 2 by pinching it. The left and right sides of the sheath body 1 are provided with positioning recesses 13, and the bottom of the two support rods 2 near the side of the sheath body 1 are provided with positioning protrusions 25. The positioning protrusions 25 are located in the positioning recesses 13. When the support rods 2 are closed, the positioning protrusions 25 are located in the positioning recesses 13, so that the support rods 2 can be well positioned after being closed.

[0024] Reference Figures 2 to 6 The sheath body 1 has an inlay groove 14 on both its left and right ends, as well as a receiving hole 15 and a mounting opening 16 communicating with the inlay groove 14. The receiving hole 15 communicates with the mounting groove 11. The receiving hole 15 and the mounting opening 16 are located on both sides of the inlay groove 14, respectively. The height of the mounting opening 16 is less than the height of the inlay groove 14. The connector 4 is embedded in the inlay groove 14, and the connecting part 41 is located in the receiving hole 15. Since the sheath body 1 is made of EVA, which has high elasticity, the connector 4 enters the inlay groove 14 through the mounting opening 16 during installation. Because the height of the mounting opening 16 is less than the height of the inlay groove 14, the connector 4 can be securely embedded in the inlay groove 14. Furthermore, the mounting opening 16 is also made of EVA material above and below it. When the tablet computer is installed in the sheath body 1, the sides of the tablet computer will not directly contact the connector 4, but will directly contact the EVA material above and below the mounting opening 16.

[0025] Reference Figures 1 to 5 The design principle of this utility model is as follows: The tablet computer is placed inside the protective cover body 1. When the tablet computer needs to be tilted for viewing, the two support rods 2 can be rotated and opened to support the protective cover body 1. The opening angle of the two support rods 2 can be adjusted. During the rotation and opening process of the support rods 2, the arc plate 32 can deform. For each rotation of the support rods 2, the arc plate 32 deforms once, and the locking teeth 33 on the arc plate 32 are locked in different tooth grooves 22.

[0026] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto.
