DETAILED DESCRIPTION OF EMBODIMENTS

(6) The specific embodiments of the disclosure will be further explained in conjunction with the accompanying drawings.

(7) In the description of the disclosure, it should be noted that terms such as center, up, down, left, right, vertical, horizontal, in, and out refer to the directions or positional relationships as shown in the accompanying drawings. These terms are used solely for the purpose of describing the disclosure and simplifying the description, and do not indicate or imply that the devices or components referred to must have specific orientations or be constructed and operated in specific directions. Therefore, they should not be understood as limitations on the disclosure.

(8) In the description of the disclosure, it should be noted that unless otherwise specifically defined and limited, terms such as installed, provided with and connected should be broadly understood. For example, connected can mean a rigid connection, a detachable connection, or being formed as one piece; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediary; it can be an internal connection within two components. For those skilled in the art, the specific meaning of the aforementioned terms in the context of the disclosure can be understood based on the specific circumstances.

(9) As shown in FIGS. 1-4, a magnetically-attracted quick connection device includes a male connecting head A and a female connecting head B, and the male connecting head A can be inserted into the female connecting head B. The male connecting head A includes a male seat 1, a first magnet 2, limiting beads 3, a thrust ring 4, a spring 5 and a male cover 6. The first magnet 2 is installed at the front end of the male seat 1 and inside the male seat 1, and the thrust ring 4 is installed at the rear end of the male seat 1. The number of the limiting beads 3 is multiple, and the multiple limiting beads 3 are located between the male seat 1 and the thrust ring 4. The spring 5 is installed between the thrust ring 4 and the male cover 6. The female connecting head B includes a female seat 7, a female magnet seat 8 and a second magnet 9, the female seat 7 defines a slot 10, the female magnet seat 8 is installed at the end of the slot 10, and the second magnet 9 is installed inside the female magnet seat 8. The second magnet 9 attracts the first magnet 2 to guide the male seat 1 to be quickly inserted into the slot 10, and the spring 5 drives the thrust ring 4 to move forward to make the limiting beads 3 abut against the inner wall of the female seat 7.

(10) Specifically, the male connecting head A further includes a first screw 11, the head part of the first screw 11 abuts against the first magnet 2, and the rod part of the first screw 11 passes through the inner wall of the male seat 1 and then is threaded with the male cover 6.

(11) As shown in FIG. 5, multiple limiting blocks 12 are arranged in front of the thrust ring 4, and every two adjacent limiting blocks 12 define a limiting groove 13. Multiple inserting plates 14 matched with the limiting grooves 13 are arranged behind the male seat 1. The multiple limiting blocks 12 are circumferentially arranged around the central axis of the thrust ring 4 to form a central groove 15, the male seat 1 is provided with a cylinder 16 inserted into the central groove 15, and each limiting block 12 is provided with a limiting step 17 abutting against the corresponding limiting bead 3. The spring 5 is sleeved on the outer peripheral side of the cylinder 16. An end of the spring 5 abuts against the thrust ring 4 and the other end of the spring 5 abuts against the male cover 6. Under normal conditions, the spring 5 drives the thrust ring 4 to move forward, and the limiting steps 17 of the thrust ring 4 abut against the limiting beads 3, so that the limiting beads 3 can limit the male connecting head from pulling out. When the male connecting head and the female connecting head are to be disassembled, the thrust ring 4 is pulled back to make the limiting steps 17 not abut against the limiting beads 3.

(12) Specifically, the female connecting head B further includes a second screw 18 and a nut 19, the head part of the second screw 18 abuts against the second magnet 9, and the rod part of the second screw 18 passes through the female seat 7 and the female magnet seat 8 and is threaded with the nut 19.

(13) The above content is a further detailed description of the disclosure in combination with the specific preferred embodiments, and it cannot be considered that the embodiments of the disclosure are limited to these descriptions. For those skilled in the related art, some simple deductions or substitutions can be made without departing from the concept of the disclosure, which should be regarded as belonging to the protection scope of the disclosure.
