Detailed Implementation

[0026] 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.

[0027] Example

[0028] Please see Figure 1-7In this embodiment of the present invention, a quick-release and quick-install shielding ring includes a shielding ring body 100, a connecting component 200, and a fixing component 300. The shielding ring body 100 has an elliptical ring structure and includes a left U-shaped ring 110 and a right U-shaped ring 120. Both ends of the left U-shaped ring 110 are fixedly connected to a first docking ring 111, and both ends of the right U-shaped ring 120 are fixedly connected to a second docking ring 121. The second docking ring 121 is inserted into the first docking ring 111. The outer walls of the first docking ring 111 and the second docking ring 121 are respectively provided with a first insertion groove 112 and a second insertion groove 122. The outer walls of the two first docking rings 111 and the two second docking rings 121 are respectively provided with an opening groove 113 and an opening groove 123. Two connecting components 200 are provided for connecting the left U-shaped ring 110 and the right U-shaped ring 120. The connecting components 200 include... The device includes a fixing base 210, which is circular at one end and rectangular at the other. The fixing base 210 has a cavity 211 inside, which is approximately cross-shaped. Two plug-in blocks 220 are symmetrically slidably connected inside the cavity 211. The outer wall of the fixing base 210 has a slot for the two plug-in blocks 220 to pass through. The inner diameter of the mating ring 121 matches the outer diameter of the circular position of the fixing base 210. A threaded rod 230 is screwed into the cavity 211. A tapered head 240 is fixedly connected to the end of the threaded rod 230 facing the plug-in block 220. A knob 231 is fixedly connected to the ends of the two threaded rods 230 extending to the outside of the fixing base 210. A chamfer is provided at the position of the tapered head 240 near the close ends of the two plug-in blocks 220. The fixing assembly 300 is connected to two connecting assemblies 200 and is used to install the shielding ring body 100 on the power equipment.

[0029] Specifically, during installation, the two plug-in blocks 220 are retracted into the cavity 211 by default. The two mating rings 121 are slidably fitted onto the circular positions of the two fixing seats 210, with the rectangular outer wall of the fixing seat 210 contacting the position of the opening slot 123. Then, the two mating rings 111 are slidably fitted onto the two mating rings 121, with the rectangular outer wall of the fixing seat 210 also engaging with the opening slot 113. At this point, the plug-in slots 112 and 122 correspond to the positions of the plug-in blocks 220. Rotating the knob 231 causes the threaded rod 230 to push the conical head 240 towards the position of the plug-in block 220 until the conical head 240... The plug is fully inserted between the two plug blocks 220, causing the two plug blocks 220 to extend outward and pass through the second plug slot 122 and the first plug slot 112 in sequence. This allows the connecting assembly 200 to fix the left U-shaped ring 110 and the right U-shaped ring 120 together. Then, the shielding ring body 100 is installed on the power equipment by the fixing assembly 300. When the shielding ring body 100 has a problem and needs maintenance or replacement, the knob 231 can be rotated directly, causing the threaded rod 230 to drive the conical head 240 away from the plug block 220, so that the plug block 220 can be retracted into the cavity 211. At this time, the left U-shaped ring 110 and the right U-shaped ring 120 can be quickly disassembled and separated.

[0030] like Figure 6-7 As shown, in this embodiment, two sliding grooves 212 are provided on the two opposite inner walls of the cavity 211 in the fixed base 210, and sliders 221 are fixedly connected to the two side walls of the two plug blocks 220. The sliders 221 are slidably connected to their corresponding sliding grooves 212, and the sliders 221 and the inner walls of the sliding grooves 212 are connected by compression springs 222.

[0031] In this embodiment, under the elastic force of the compression spring 222, the two plug blocks 220 are naturally abutted and retracted inside the cavity 211 when there is no external force. After the first docking ring 111 and the second docking ring 121 are docked together and sleeved on the circular outer wall of the fixed base 210, the knob 231 is rotated to make the conical head 240 press the two plug blocks 220, thereby causing the two plug blocks 220 to move away from each other and penetrate the first plug slot 112 and the second plug slot 122. When the conical head 240 no longer presses the two plug blocks 220, the two plug blocks 220 will move closer to each other under the rebound force of the compression spring 222 and return to their initial position in the cavity 211.

[0032] like Figure 3-5 As shown, in this embodiment, a collar 260 is fixedly fitted onto the outer wall of the fixing base 210. The inner diameter of the collar 260 matches the outer diameter of the cavity 211. Insertion grooves 261 are provided on the inner wall of the collar 260 at positions corresponding to the two insertion blocks 220.

[0033] In practice, a certain gap is left between the collar 260 and the circular position of the fixed base 210. The second docking ring 121 and the first docking ring 111 are both inserted into the gap position. The inner arc surface of the collar 260 is in contact with the outer arc surface of the first docking ring 111. After rotating the knob 231, the insertion block 220 will pass through the second insertion slot 122 and the first insertion slot 112 in sequence, and finally the end is embedded in the third insertion slot 261, which enhances the connection strength of the three. At the same time, the collar 260 also covers the joint of the left U-shaped ring 110 and the right U-shaped ring 120.

[0034] like Figure 3-4 As shown, in this embodiment, the top surfaces of the two fixed seats 210 are fixedly connected to the connecting seats 250, and the fixing assembly 300 includes two arc-shaped clamps 310. The outer walls of the two arc-shaped clamps 310 are fixedly connected to the connecting rods 320, and the bottom ends of the two connecting rods 320 are rotatably connected to the two connecting seats 250 respectively.

[0035] In practice, the two arc-shaped clamps 310 are detachably fixed together by bolts, and the bottom end of the connecting rod 320 is rotatably connected to the connecting seat 250, so that the two arc-shaped clamps 310 can adapt to different sizes of installation positions.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
