Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved by the present application more clear, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The utility model provides a pull rod telescopic locking mechanism as shown in the figure, which is characterized in that: including pull rod main part 1 and locking piece 2, pull rod main part 1 comprises thin pull rod 1.1 and thick pull rod 1.2, thin pull rod 1.1 bottom fixedly connected with magnet casket 3, two magnet casket magnets 4 are all installed to both sides in the magnet casket 3, locking piece 2 comprises lock body 5 and lock body lid 6, lockpin 7 is all installed to both sides in the lock body 5, be equipped with magnet mounting 8 in the lockpin 7, install two lockpin magnet 9 in the magnet mounting 8, be connected through spring 10 between lockpin 7 and the lock body 5.

In the utility model, the thick pull rod 1.2 is sleeved outside the thin pull rod 1.1 and is in sliding connection.

In the utility model, the magnet box 3 is positioned in the thick pull rod 1.2, and the magnetic poles of the two magnet box magnets 4 positioned in the magnet box 3 are opposite.

The locking element 2 is in the utility model mutually matched with the thick pull rod 1.2.

In the utility model, the lock body cover 6 is positioned at the bottom of the lock body 5 and is mutually inserted, the lock body cover 6 is provided with the insertion block 6.1, and the bottom of the lock body 5 is provided with the insertion groove matched with the insertion block 6.1.
