Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: an automatic connect and automatic disconnect device comprising: a driving member chute 10, a driven member chute 20, a top plate 50 and a spring pull rod 60.

The driving slide bar 11 is slidably mounted inside the driving piece sliding groove 10, one end of the driving slide bar 11 is hinged to a hook rod 30, and one end of the hook rod 30 is fixedly connected with a driving hook 31.

Further, the hook rod 30 and the active hook 31 are made of iron material.

A driven slide rod 21 is slidably mounted inside the driven slide groove 20, and one end of the driven slide rod 21 is fixedly connected with a driven hook 40.

Further, the follower slide bar 21 can slide inside the follower link 20.

Wherein, a magnet 51 is fixedly arranged at the bottom end inside the top plate 50.

Further, when the driving hook 31 rotates to a certain angle, it will touch the magnet 51 at the bottom of the top plate 50, at this time, the magnet 51 will firmly attract the driving hook 31, when the driving slide bar 11 moves leftwards, the driving hook 31 will move leftwards close to the bottom of the top plate 50, the driven hook 40 will move along with the driving slide bar 11 because it is caught by the driving hook 31 until the spring force is released, when the driving hook 31 moves to the leftmost end of the magnet 51, the driving hook 31 will move leftwards again and fall off the attraction of the magnet 51.

The top plate 50 is fixedly mounted on the top end surface of the follower sliding groove 20, and the spring pull rod 60 is slidably mounted on one end of the follower sliding groove 20.

One end of the spring pull rod 60 extends into the follower sliding groove 20 and is fixedly connected to one end of the driven sliding rod 21, the other end of the spring pull rod 60 extends to the outside of the follower sliding groove 20 and is provided with a nut 63 in a threaded manner, a return spring 61 is sleeved outside the spring pull rod 60 positioned in the follower sliding groove 20, and a fixing jacket 62 is fixedly installed on one side, located on the return spring 61, of the spring pull rod 60.

Further, when the driving slide bar 11 moves rightwards, the driving hook head 31 will abut against the right wall of the groove in the driven hook head 40, and further push the driven slide bar 21 to move rightwards, so as to push the spring pull rod 60 to move out of the follower chute 20, when the fixed jacket 62 moves to the position of the return spring 61, the return spring 61 can be compressed, and when the driven slide bar 21 has no acting force, the driven hook head 40 returns to the initial state under the spring force of the return spring 61.

The two sides of the hook rod 30 are fixedly connected with a pin rod 32, and one end of the follower chute 20 far away from the spring pull rod 60 is provided with a bevel end 22.

Further, the pin shaft 32, which is cylindrical in configuration, moves upwardly along the beveled end 22.

One end of the driving sliding rod 11 is fixedly connected with a hinge joint 12, and the hinge joint 12 is hinged with the hook rod 30 through a pin shaft 13.

Further, one end of the hook bar 30 can be rotated at the hinge 12.

Wherein, the driving hook head 31 has an inclined surface at one end, and the driven hook head 40 has an inclined surface at one end.

The working principle is as follows: when in connection: when the initiative slide bar 11 drives the eave tile pole 30 and moves right, initiative eave tile 31 and driven eave tile 40 contact, because the effect initiative eave tile 31 on inclined plane can be round axle anticlockwise rotation, when initiative slide bar 11 continues to push away initiative eave tile 31 and moves right, because there is not the support of driven eave tile 40, the eave tile of initiative eave tile 31 can fall into the groove of driven eave tile 40, just so accomplished the connection, initiative slide bar 11 establishes the relation of connection through initiative eave tile 31 and driven eave tile 40, driven eave tile 40 can be along with initiative slide bar 11 moves left, during the unhook: in the initial position when the driving hook head 31 is connected with the driven hook head 40, if the driving slide bar 11 moves rightwards, the driving hook head 31 will abut against the right wall of the groove in the driven hook head 40, and further push the driven hook head 40 to move rightwards against the spring force, when the driving slide bar 11 moves rightwards all the time, the pin shaft 32 on the driving hook head 31 will touch the inclined plane end 22 at the left end of the driven member sliding groove 20, the driving hook head 31 rotates anticlockwise, when the driving hook head 31 rotates to a certain angle, the driving hook head 31 will touch the magnet 51 at the bottom of the top plate 50, at this time, the magnet 51 will firmly suck the driving hook head 31, when the driving slide bar 11 moves leftwards, the driving hook head 31 will move leftwards clinging to the bottom of the top plate 50, the driven hook head 40 will move along with the driving slide bar 11 because it is blocked by the driving hook head 31, until the spring force is released, then moving the driving hook 31 to the left will get rid of the attraction of the magnet 51 and fall down, the driven hook 40 will return to the initial state due to the action of the spring force to complete the automatic unhooking, according to the above principle, the same structure of the driven member chute 20 is made on the driving member chute 10, and the magnet is installed on the driven member chute, so that the automatic unhooking of the member can be realized when the member moves from the right to the left. Since the principle is the same, it is not described in detail.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
