the axial limiting structure comprises a first magnetic attraction piece 110 and a second magnetic attraction piece 200 which are mutually attracted and limited and axially separate from the beam core 100 and the base 300; the top cover 400 cooperates with the base 300 to encapsulate the central bundle core 100.
The base 300 and the middle beam core 100 realize circumferential limiting of the base and the middle beam core through the clamping groove 321 and the protrusion 111, and realize axial limiting of the base and the middle beam core through the first magnetic attraction piece 110 and the second magnetic attraction piece 200. When the middle beam core 100 needs to be installed, the protrusion 111 slides in along the opening 322 of the clamping groove 321 until the protrusion abuts against the limiting part 323 to limit, so that the relative rotation of the middle beam core 100 and the base 300 is limited, and the axial separation of the middle beam core 100 and the base 300 is limited under the action of the first magnetic attraction piece 110 and the second magnetic attraction piece 200. Therefore, compared to the prior art, the beam core 100 in the present application needs to overcome the attraction force between the first magnetic attraction member 110 and the second magnetic attraction member 200 to move axially to disengage from the limiting portion 323, and then can rotate along the guiding portion 324 to disengage from the base 300, so that the beam core has a drop-preventing effect compared to the prior art.
The base 300 includes an outer bottom tube 310 and an inner bottom tube 320, a clamping groove 321 is provided on the inner bottom tube 320, and the second magnetic attraction member 200 is clamped and fixed between the inner bottom tube 320 and the outer bottom tube 310. In order to facilitate the assembly between the inner bottom tube 320 and the outer bottom tube 310, the inner wall of the outer bottom tube 310 is provided with a limit groove 311, the outer circumference of the inner bottom tube 320 is provided with a limit ring 325 which is matched with the limit groove 311 to axially limit, wherein the limit ring 325 divides the inner bottom tube 320 into a first section 330 and a second section 340 which are opposite, the clamping groove 321 is arranged at the first section 330, the opening 322 is arranged at the top end of the first section 330, and the limit part 323 extends to the limit ring 325. Of course, in order to facilitate circumferential spacing between the inner bottom tube 320 and the outer bottom tube 310, the second section 340 is provided with axially arranged spacing ribs 341, and the inner wall of the outer bottom tube 310 is provided with spacing keys 312 cooperating with the spacing ribs 341.
Referring to fig. 3 to 4, in order to prevent the protrusion 111 from easily coming out of the stopper 323, the opening 322 and the stopper 323 extend in the axial direction in the present embodiment. Bao Zhuangguan even if the protrusion 111 falls down, the protrusion 111 is displaced axially with respect to the stopper 323, and at this time, the protrusion 111 is reset by the attraction of the first magnetic attraction member 110 and the second magnetic attraction member 200, so that the protrusion has a further fall-preventing effect. When the middle beam core 100 needs to be replaced, the middle beam core 100 and the base 300 are first applied with a force in opposite directions in the axial direction, then the middle beam core 100 is rotated (in this embodiment, the rotation direction is clockwise) along the guiding portion 324 to the opening portion 322, and finally the middle beam core 100 and the base 300 are separated by applying a force in the axial direction. When a new middle beam core 100 is installed, the protrusion 111 is installed in the opening 322 of the clamping groove 321, and at this time, under the action of the second magnetic attraction piece 200, the first magnetic attraction piece 110 drives the middle beam core 100 to slide downwards until being clamped with the limiting part 323 (at this time, the first magnetic attraction piece 110 and the second magnetic attraction piece 200 are attracted), so that the installation is more convenient. In this embodiment, the second magnetic attraction member 200 is made of a magnet, and the first magnetic attraction member 110 is made of a weighted PP material.
