[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a plastic core inner cover that is easy to disassemble and assemble, and has the following beneficial effects:

[0015] This easily detachable plastic core cover utilizes a snap-fit ​​assembly. During disassembly, pulling the two left and right pull plates moves the pull rope upwards. The cooperation of the pull rope, guide wheel, and traction rope causes the two left and right positioning plates to move relative to each other. The two positioning plates then drive the two snap-fit ​​shafts to move relative to each other until both snap-fit ​​shafts are inside the connecting frame. Finally, pulling the connecting plate upwards removes the plastic core cover from the connecting frame, thus facilitating the disassembly of the plastic core cover without the need to remove multiple sets of screws one by one with a screwdriver. This makes disassembly more convenient and improves the practicality of the device. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-2A conveniently detachable plastic core inner cover includes a connecting frame 1, a connecting plate 2 placed on the top of the connecting frame 1, and a plastic core inner cover 3 extending to the bottom of the connecting plate 2. The top of the connecting plate 2 has a through hole adapted to the plastic core inner cover 3. Two connecting frames 4, symmetrically distributed on both the left and right sides of the bottom of the connecting plate 2, are provided. The top of the connecting frame 1 has two grooves adapted to the connecting frames 4, symmetrically distributed on both sides. Both connecting frames 4 extend into the interior of the connecting frame 1. A snap-fit ​​assembly 5, which engages with the inner wall of the connecting frame 1, is movably connected to the inner wall of each connecting frame 4. The top of the snap-fit ​​assembly 5 extends to the top of the connecting plate 2. The snap-fit ​​assembly 5 includes a positioning plate 51. Two positioning plates 51, symmetrically distributed on both sides, are fixedly connected to the inner wall of the connecting frame 4. A sliding groove adapted to the moving trajectory of the positioning plate 51 is provided on the inner wall of the connecting frame 4. Each of the two positioning plates 51 is movably connected to a snap-fit ​​shaft 52 extending to its opposite side. The inner walls of the grooves are connected to snap-fit ​​slots on the connecting frame 1 that are adapted to the snap-fit ​​shafts 52. The opposite sides of the two snap-fit ​​shafts 52 extend to the left and right sides of the connecting frame 4 and snap-fit ​​with the inner walls of the connecting frame 1. The inner bottom wall of the connecting frame 4 is fixedly connected to two guide wheels 53 that are symmetrically distributed on the left and right. The two guide wheels 53 are located between the two positioning plates 51. A traction rope 54 is fixedly connected between the two positioning plates 51. The traction rope 54 passes through the two guide wheels 53 in sequence. Compression springs 55 sleeved on the outside of the snap-fit ​​shafts 52 are fixedly connected between the opposite sides of the two positioning plates 51 and the left and right sides of the inner walls of the connecting frame 4. A pull rope 56 extending to the top of the connecting plate 2 is fixedly connected to the top of the traction rope 54. A pull plate is fixedly connected to the top of the pull rope 56. The pull rope 56 is located between the two guide wheels 53.

[0021] It is worth noting that the standard parts used in this application can all be purchased from the market, and the specific connection methods of each part are all connected by conventional means such as bolts, rivets, and welding that are mature in the prior art. Furthermore, the machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art. The contents not described in detail in the description belong to the prior art known to those skilled in the art, and will not be described in detail here.

[0022] In summary, this easily detachable plastic core cover, through the setting of the snap-fit ​​assembly 5, allows for easy disassembly. During disassembly, pulling the left and right pull plates moves the pull rope 56 upwards. The cooperation of the pull rope 56, guide wheel 53, and traction rope 54 causes the left and right positioning plates 51 to move relative to each other. The two positioning plates 51 then move the two snap-fit ​​shafts 52 relative to each other until both snap-fit ​​shafts 52 are inside the connecting frame 4. Finally, pulling the connecting plate 2 upwards removes the plastic core cover 3 from the connecting frame 1, thus achieving easy disassembly of the plastic core cover. This eliminates the need to disassemble multiple sets of screws individually with a screwdriver, making disassembly more convenient and improving the practicality of the device. It also solves the problem that traditional plastic core covers often use multiple sets of screws for fixing, requiring tedious disassembly by disassembling each set of screws individually with a screwdriver.
