[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, a multifunctional integrated shielding cover includes a shielding cover body 1. The lower end of the shielding cover body 1 is provided with a support rod 2. The support rod 2 is mainly used to support the shielding cover body 1, keeping it in a certain position and height for easy installation and fixing. It also serves as a bridge connecting the shielding cover body 1 and external equipment, connecting the shielding cover body 1 to the external power equipment. The support rod 2 has a certain strength and rigidity, and can withstand the weight of the shielding cover body 1 and the action of external forces. Through the connection with the shielding cover body 1 and the external power equipment, the stable installation of the entire shielding structure is achieved. The bottom of the support rod 2 is provided with a flange 24, which is integrated with the support rod 2. The flange 24 usually has multiple mounting holes, corresponding to the mounting holes on the external equipment. By passing bolts through mounting holes and tightening nuts, flange 24 is tightly connected to external equipment, thereby fixing support rod 2 to external equipment. Support rod 2 has a locking block 21 at its top, with external threads on its outer periphery. The shielding cover body 1 has a matching fastening groove 14 at its inner center. Support rod 2 and shielding cover body 1 are threaded together. When support rod 2 is rotated, the external threads on locking block 21 engage with the internal threads in fastening groove 14, causing relative movement between support rod 2 and shielding cover body 1, thus achieving connection and separation. This threaded connection method has advantages such as reliable connection and convenient disassembly. The internal threads of fastening groove 14 and the external threads of locking block 21 cooperate, and by rotating support rod 2, they engage tightly, thus fixing support rod 2 to shielding cover body 1. The design of fastening groove 14 also ensures coaxiality between support rod 2 and shielding cover body 1, improving connection stability.

[0026] The shielding cover body 1 is also equipped with multiple auxiliary fastening devices inside. These auxiliary fastening devices are used to enhance the connection stability between the shielding cover body 1 and the support rod 2 and improve the shielding effect. They can provide additional fastening force on the basis of threaded connection to prevent loosening between the shielding cover body 1 and the support rod 2.

[0027] The auxiliary fastening device is provided in four parts, which are equidistantly arranged along the center circumference of the fastening groove 14. Each auxiliary fastening device includes a cavity 11, and a fastening spring 12 is provided inside the cavity 11. The top of the fastening spring 12 is fixed to the top wall of the cavity 11, and a ball bearing 15 is provided at the bottom of the fastening spring 12. A fastening cover 13 is provided at the bottom of the cavity 11. The outer peripheral wall of the fastening cover 13 is threaded and is connected to the cavity 11 by the thread.

[0028] The ball bearing 15 is fixedly connected to the fastening spring 12, and part of the ball bearing 15 passes through the fastening cover 13.

[0029] The lower end of the locking block 21 at the top of the support rod 2 is provided with a chuck 22. The diameter of the chuck 22 is larger than that of the locking block 21. The shielding cover body 1 is provided with a matching slot. When the support rod 2 is inserted into the shielding cover body 1, the chuck 22 will be locked into the slot. Through the friction and positioning effect between the chuck 22 and the slot, relative rotation and loosening between the support rod 2 and the shielding cover body 1 are prevented. When the support rod 2 is connected to the shielding cover body 1, the chuck 22 is locked into the slot on the shielding cover body 1, further enhancing the connection stability and preventing relative rotation between the shielding cover body 1 and the support rod 2.

[0030] The support rod 2 has an extension rod 3 at its bottom. The bottom of the support rod 2 and the top of the extension rod 3 are connected and fixed by bolts and fasteners 4. There are multiple extension rods 3, which are connected to the bottom of the support rod 2 by bolts and fasteners 4 to form a whole. By increasing the number of extension rods 3, the height of the support rod 2 can be flexibly adjusted so that the shielding cover body 1 can reach a suitable installation position.

[0031] The working principle of this utility model is as follows: When in use, determine whether an extension rod 3 is needed and the number of extension rods 3 according to the actual installation height requirements, and connect the extension rods 3 to the bottom of the support rod 2 in sequence with bolt fasteners 4;

[0032] Align the locking block 21 at the top of the support rod 2 with the fastening groove 14 inside the shield body 1, and slowly rotate the support rod 2 so that the external thread on the locking block 21 begins to engage with the internal thread in the fastening groove 14. Continue to rotate the support rod 2 until the locking block 21 is fully inserted into the fastening groove 14. At this point, the support rod 2 and the shield body 1 have achieved a preliminary threaded connection.

[0033] During the initial connection between the support rod 2 and the shielding cover body 1, the auxiliary fastening device starts to work. Under the action of its own elastic force, the fastening spring 12 pushes the ball 15 downward, so that the ball 15 presses against the surface of the support rod 2. As the support rod 2 is further screwed in, the pressure between the ball 15 and the support rod 2 gradually increases, and the fastening force provided by the auxiliary fastening device is also continuously enhanced, thereby enhancing the connection stability between the support rod 2 and the shielding cover body 1.

[0034] When the support rod 2 is connected to the shielding cover body 1 to a certain extent, the chuck 22 at the lower end of the top chuck block 21 of the support rod 2 will be engaged in the slot on the shielding cover body 1. The cooperation between the chuck 22 and the slot further restricts the relative rotation between the support rod 2 and the shielding cover body 1, ensuring that the relative position between the two is fixed and improving the reliability of the connection.

[0035] When it is necessary to disassemble the shielding cover, first loosen the bolts and nuts of the fixing flange 24, remove the support rod 2 or extension rod 3 from the external equipment, and then rotate the support rod 2 to separate the locking block 21 from the fastening groove 14. At the same time, the chuck 22 is disengaged from the groove. During the rotation, the ball bearing 15 of the auxiliary fastening device retracts into the cavity 11 under the action of the fastening spring 12, which facilitates the separation of the support rod 2 from the shielding cover body 1.

[0036] Finally, separate the support rod 2 from the extension rod 3 to complete the disassembly of the entire shielding device.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
