Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] Next, the embodiments of the present invention will be further described in detail with reference to the drawings as follows:

[0026] A child safety insurance handle includes a base 1 and a handle 2 connected to one side thereof. A handle seat 3 is linked between the handle 2 and the base 1, and the handle 2 is rotatably connected to the base 1 through the handle seat 3. A connecting block 4 is longitudinally inserted into one end of the handle 2 through the handle seat 3, and the connecting block 4 is longitudinally movably inserted into the handle 2. A locking limiting member 5 penetrates through the handle seat 3, and a return spring 6 for its movable reset is arranged on the locking limiting member 5. One end of the locking limiting member 5 penetrates through the connecting block 4 and cooperates with the handle 2, and the other end is unlocked / locked with the base 1. The handle 2 is provided with a locking groove 7 and a clearance position 8 corresponding to the locking limiting member 5. When one end of the locking limiting member 5 is arranged in the locking groove 7, the other end of the locking limiting member 5 is locked with the base 1 to lock and limit the handle 2. When the handle 2 moves longitudinally to make one end of the locking limiting member 5 arranged in the clearance position 8, the other end of the locking limiting member 5 is unlocked and separated from the base 1, so that the handle 2 can rotate.

[0027] When the handle 2 is in its original position, one end of the locking and limiting member 5 abuts against the locking groove 7, and the other end passes through the card slot 17, so that the handle 2 and the handle base 3 are locked and limited, realizing the function of locking the handle 2 to prevent children from accidentally opening the window. When the handle 2 is pulled in the opposite direction of the insertion of the connecting block 4, the locking groove 7 moves, so that one end of the locking and limiting member 5 moves into the avoidance space 8 through the return spring 6. A slope structure is adopted between the avoidance space 8 and the locking groove 7, which can facilitate the relative movement of the locking and limiting member 5 between the avoidance space 8 and the locking groove 7. The other end of the locking and limiting member 5 leaves the card slot 17, realizing the unlocking of the handle 2, so that the handle 2 can be rotated to unlock the door or window.

[0028] The locking and limiting member 5 includes a locking head 9 and a limiting post 10. A stepped structure is formed between the locking head 9 and the limiting post 10, so that the return spring 6 passes through the limiting post 10 and is arranged between the locking head 9 and the handle base 3. One end of the locking head 9 located in the locking groove 7 has an arc-shaped structure or is provided with an arc chamfer, and the locking groove 7 corresponds to the locking head 9 and has an arc-shaped sliding groove structure.

[0029] One end of the handle 2 located at the connecting block 4 is connected with a limiting block 11 by a screw. The connecting block 4 is provided with an activity groove 12 for the limiting block 11 to be limited and translated, which can make the translation distance of the handle 2 between the locking and limiting member 5 abutting against the avoidance space 8 and the locking groove 7, effectively preventing the handle 2 from falling off.

[0030] A locking sleeve 13 with a stepped structure is penetrated through one end of the base 1 opposite to the handle base 3. One end of the locking sleeve 13 is rotatably connected with the base 1, and the other end is inserted and matched with the handle base 3 and then connected by a screw 14. A gasket 15 is arranged between the locking sleeve 13 and the base 1. One end of the base 1 located at the handle base 3 is clamped with a locking ring 16 that cooperates with the locking and limiting member 5. The locking ring 16 is provided with a card slot 17 corresponding to the locking and limiting member 5. The locking ring 16 is arranged between the base 1 and the handle base 3, and is connected with the handle base 3 in cooperation by the locking sleeve 13 passing through the base 1 and the locking ring 16 in sequence. A second spring 21 is penetrated through one end of the locking ring 16 located at the base 1.

[0031] Axial array of limiting grooves 18 is opened on one side of the base 1 where the locking sleeve 13 is located. First springs 19 are penetrated through the limiting grooves 18, and marbles 20 are arranged between the first springs 19 and the locking sleeve 13.

[0032] Through the cooperation between the handle 2 and the locking and limiting member 5, the unlocking / locking between the handle 2 and the base 1 is realized. When one end of the locking and limiting member 5 is arranged in the avoidance position 8, the other end is unlocked from the base 1, enabling the handle 2 to rotate. When the handle 2 axially moves until one end of the locking and limiting member 5 is arranged in the locking groove 7, the other end of the locking and limiting member 5 cooperates with the base 1 to limit the handle 2, which can effectively reduce the risk of the window or door being opened due to a child accidentally turning the handle 2, thus having a good protective effect on the personal safety of the child, and effectively preventing the window or door from being opened by rotating the handle under accidental touch or non-human action, improving the safety performance of the window or door and being easy to install.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
