It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0042] Combination Figure 1 and Figure 2 As shown, the present invention mainly relates to: a handle, comprising a mounting assembly 1, a gripping element 3, and a force storage component 4 connecting the gripping element 3 and the mounting assembly 1. One end of the force storage component 4 is connected to the gripping element 3, and the other end of the force storage component 4 is connected to the mounting assembly 1. Preferably, the force storage component 4 is a spring. The mounting assembly 1 is configured to be docked and installed with a door body.

[0043] Combination Figure 3 As shown, the mounting assembly 1 includes a receiving cavity 11 , a receiving opening 12 communicating with the receiving cavity 11 , and a self-locking mechanism 2 disposed in the receiving cavity 11 .

[0044] The holding element 3 is installed in the accommodating cavity 11 and locked with the self-locking mechanism 2 . The holding element 3 can retract or extend relative to the accommodating cavity 11 through the accommodating opening 12 .

[0045] Specifically, when the gripping element 3 moves toward the self-locking mechanism 2, the gripping element 3 retracts relative to the accommodating cavity 11 through the accommodating opening 12. When the gripping element 3 moves away from the self-locking mechanism 2, the gripping element 3 extends relative to the accommodating cavity 11 through the accommodating opening 12. The gripping element 3 has two states: retracted and extended. The gripping element 3 switches between the retracted state and the extended state.

[0046] The gripping element 3 is moved towards the self-locking mechanism 2 by the external force, so that the self-locking mechanism 2 locks the gripping element 3, and the force storage mechanism is deformed at the same time.

[0047] The process of the gripping element 3 changing from the extended state to the retracted state is as follows: the user manually presses the gripping element 3 in a direction close to the self-locking mechanism 2 until the gripping element 3 is locked by the self-locking mechanism 2 .

[0048] The holding element 3 is separated from the self-locking mechanism 2 by an external force, and the force storage structure recovers its deformation to drive the holding element 3 to move in a direction away from the self-locking mechanism 2.

[0049] The process of the gripping element 3 changing from the retracted state to the extended state: the user manually presses the gripping element 3, the gripping element 3 is separated from the self-locking mechanism 2, and the force storage structure recovers its deformation to drive the gripping element 3 to move away from the self-locking mechanism 2.

Preferably, a connecting spring 29 is connected between the rear wall of the lock core seat 24 and the inner side of the rear wall of the lock housing 21.

[0055] The locking member 25 retracts or extends out of the inner cavity 22 through the opening 23, so that the locking member 25 is locked or unlocked with the lock hook 33. The user presses the grip portion 31 backward, and the lock hook 33 moves backward until the lock hook 33 contacts the lock core seat 24. The lock hook 33 drives the lock core structure backward together, and the locking member 25 retracts into the inner cavity 22 and locks the lock hook 33 at the same time, so that the grip element 3 becomes a retracted state.

[0056] Combination Figure 3 , Figure 4 As shown, the connection unit includes a connection plate 26 hinged to the lock core seat 24 and a guide column 27 arranged on the connection plate 26. The inner wall of the lock housing 21 is provided with a guide groove 211 matched with the guide column 27. The connection unit is connected to the rear wall of the lock core seat 24.

When the guide column 27 is limitedly engaged in the limit groove 281, the locking member 25 is retracted into the inner cavity 22 and locked. When the guide column 27 is limitedly disengaged from the limit groove 281, the locking member 25 extends out of the inner cavity 22. Preferably, the entrance of the limit groove 281 is arranged rearward.

[0058] The user presses the holding portion 31 backwards, and the lock hook 33 moves backwards until the lock hook 33 contacts the lock core seat 24. The lock hook 33 drives the lock core structure backwards, and the guide column 27 moves backwards along the guide groove 211 until the guide column 27 is stuck in the limit groove 281. At the same time, the locking member 25 retracts into the inner cavity 22 to lock the lock hook 33. The holding element 3 becomes retracted, and the connecting spring 29 accumulates force.

[0059] The user presses the gripping portion 31 backward, the guide column 27 disengages from the limiting groove 281, the connecting spring 29 restores its deformation, the connecting spring 29 drives the lock core seat 24 and the locking member 25 to move forward, the locking member 25 is unlocked from the lock hook 33, and the force storage component 4 restores its deformation to drive the gripping element 3 to move in the direction away from the self-locking mechanism 2.

[0060] Further, the number of the locking members 25 is set to 2. The two locking members 25 are symmetrically connected to the lock core seat 24. The lock hook 33 is set to a T-shaped structure, and the lock hook 33 includes a connecting portion connected to the connecting sleeve 32 and a lock hook portion extending backward from the connecting portion.

[0062] When the limiting boss 34 is limitedly abutted against the abutting portion 15, the gripping element 3 is at the limit position of extending out of the accommodating cavity 11. The abutting portion 15 and the limiting boss 34 are arranged to prevent the force storage component 4 from being in the limit working state, thereby increasing the service life of the force storage component 4 and allowing the gripping element 3 to be smoothly extended or retracted.

[0063] Furthermore, the mounting assembly 1 comprises a shell 13 and a liner bracket 14 disposed in the shell 13. The liner bracket 14 defines an accommodating cavity 11, and the shell 13 and the liner bracket 14 together define an accommodating opening 12.

[0064] The end of the housing 13 having the accommodating opening 12 is formed with an abutting portion 15. The front end of the liner bracket 14 is open, the housing 13 forms the abutting portion 15, and the limiting boss 34 is limited and abutted against the abutting portion 15.

The extension direction of the guide opening 622 is the same as the moving direction of the gripping element 3. The guide block 614 extends out of the guide opening 622. When the gripping element 3 is at the two extreme positions of movement, the guide block 614 abuts against the two ends of the guide opening 622 respectively.

[0073] Furthermore, when the holding element 3 is in the retracted state, the guide block 614 abuts against the rear end of the connecting sleeve 32 .

[0074] Furthermore, the guide column body 611 is provided with a mounting hole 612 with an opening 23 facing the guide seat 62.
