[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 A communication device back cover that is easy to assemble includes a communication device back cover body 1. A connecting frame 2 is fixedly mounted on the side of the communication device back cover body 1. A circular groove 12 is opened on the side of the connecting frame 2. A diagonal rod 3 is slidably sleeved on the inner wall of the circular groove 12. A square groove 11 is opened on the top of the connecting frame 2. A diagonal block 4 is slidably connected to the inner wall of the square groove 11. A top plate 6 is slidably connected to the top of the diagonal block 4. Through the cooperation of the diagonal rod 3 and the circular groove 12, the outer edge of the diagonal rod 3 slides in the inner wall of the circular groove 12, and then the diagonal block 4 slides in the inner wall of the square groove 11. Then the bottom of the diagonal block 4 pushes the diagonal rod 3 to move.

[0017] In a preferred embodiment, the shape and size of the inclined block 4 near the bottom side are adapted to the shape and size of the inclined rod 3 near the top side. A friction plate 10 is fixedly mounted on the side of the inclined rod 3, and the outer edge of the friction plate 10 is slidably sleeved with the inner wall of the circular groove 12. The friction plate 10 is made of rubber. When the inclined rod 3 drives the friction plate 10 to move and assists the side of the friction plate 10 to fit against the inner wall of the communication device, the friction plate 10 is used to help increase the friction force when the back cover body 1 of the communication device is erected, thereby further ensuring the stability of the device installation.

[0018] In a preferred embodiment, the inner wall of the inclined block 4 near the top is coated with an adhesive layer 5, and the top of the adhesive layer 5 overlaps with the bottom of the top plate 6. The top of the top plate 6 has a connecting groove 7, and the top of the top plate 6 is connected to the inner wall of the adhesive layer 5 through the inner wall of the connecting groove 7. With the addition of the adhesive layer 5, when the top plate 6 slides on the inner wall of the inclined block 4, the bottom of the top plate 6 assists in squeezing the adhesive layer 5, thereby helping the adhesive layer 5 to be discharged to the outside. The top plate 6 adopts a detachable design, so that the top plate 6 and the inclined block 4 can be disassembled. Then, the adhesive layer 5 is applied to the inner wall of the inclined block 4, and the top plate 6 is placed on top of the adhesive layer 5. This further improves the ease of installation of the device while preventing the adhesive from leaking into the device and affecting the stable operation of the electronic components inside the device.

[0019] In a preferred embodiment, the top of the connecting frame 2 is provided with an arc-shaped groove 9, and the side of the inclined block 4 near the top is provided with a side groove 8. When the top of the inclined block 4 is at the same level as the top of the connecting frame 2, the inner wall of the arc-shaped groove 9 near the bottom is connected to the adhesive layer 5 through the inner wall of the side groove 8. Through the cooperation of the arc-shaped groove 9 and the side groove 8, when the side of the inclined block 4 slides in the inner wall of the square groove 11, the inclined block 4 drives the inner wall of the side groove 8 to connect with the inner wall of the arc-shaped groove 9. Then, when the top plate 6 squeezes the adhesive layer 5, the adhesive inside the adhesive layer 5 is discharged to the outside through the side groove 8 and the arc-shaped groove 9, thereby helping the connecting frame 2 and the communication equipment to be stably erected.

[0020] In a preferred embodiment, there are two inclined blocks 4, and the two inclined blocks 4 are slidably connected to the inner walls of the square grooves 11 on both sides of the connecting frame 2. The connection structures at the top of the two inclined blocks 4 are completely identical, and the connection structures on the side of the two inclined blocks 4 away from the back cover body 1 of the communication device are completely identical. By adding the two inclined blocks 4, the two inclined blocks 4 can slide on the square grooves 11 on both sides of the connecting frame 2, thereby assisting the stable docking and erection of the two sides of the connecting frame 2 with the communication device.

[0021] In a preferred embodiment, there are several arc-shaped grooves 9, which are divided into four groups. The four groups of arc-shaped grooves 9 are arranged in pairs on both sides of the two inclined blocks 4. By opening several arc-shaped grooves 9, after the top plate 6 squeezes the adhesive layer 5, several arc-shaped grooves 9 discharge the adhesive to the outside, thereby further improving the stability and uniformity of the coverage area when the adhesive is discharged to the outside.

[0022] Working principle: When the device is in use, the back cover body 1 of the communication device is connected to the communication device. Then, the top plate 6 first contacts the communication device, and the communication device drives the top plate 6 to move to the inner wall of the inclined block 4. The inclined block 4 then moves to the inner wall of the connecting frame 2. The bottom of the inclined block 4 pushes the outer edge of the inclined rod 3 to slide in the inner wall of the circular groove 12. When the top of the connecting frame 2 is tightly fitted with the inside of the communication device, the inclined rod 3 drives the side of the friction plate 10 to fit against the inner wall of the communication device. When the side of the top plate 6 slides on the inner wall of the inclined block 4, the top plate 6 squeezes the glue layer 5, thereby assisting the glue to be discharged through the connecting groove 7. After the inner walls of the side groove 8 and the arc groove 9 are connected, the glue layer 5 is discharged through the side groove 8 and the arc groove 9. Thus, when the connecting frame 2 and the top plate 6 are installed with the back cover of the communication device, the glue coating range is increased, thereby further ensuring the stability of the device installation.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
