[0037] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0038] In the description of this application, it should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0039] Example 1:

[0040] This embodiment provides a door handle, comprising:

[0041] Shell 1;

[0042] A lock core 2 is rotatably mounted in the housing 1 along an XZ plane;

[0043] A control assembly 3 is rotatably mounted on the housing 1 along a YZ plane and abuts against the lock cylinder 2;

[0044] A reset member 4 is installed in the housing 1 and is used to rotate and reset the control assembly 3;

[0045] When the control component 3 rotates along the YZ plane, it pushes the lock core 2 to rotate along the XZ plane.

[0046] Furthermore, the control component 3 includes:

[0047] A connecting seat 31 is rotatably mounted on the housing 1 along a YZ plane;

[0048] The first abutting member 32 is mounted on the connecting seat 31 and abuts against the lock core 2 .

[0049] The lock core 2 includes:

[0050] a protrusion 21 , the protrusion 21 being provided on the end portion of the lock cylinder 2 along the Y direction and abutting against the first abutting member 32 ;

[0051] When the connecting seat 31 rotates along the YZ plane, the first abutting member 32 pushes the protrusion 21 to rotate along the XZ plane.

[0052] In this technical solution, the connecting base 31 is a "U"-shaped structure, with a fixing rod 11 disposed in the middle of the connecting base 31. The connecting base 31 is mounted within the housing 1 via the fixing rod 11, achieving a rotatable connection with the housing 1 along the YZ plane. The lock cylinder 2 is mounted on the housing 1 and located within the connecting base 31. The lock cylinder 2 has a recessed hole structure, and the fixing rod 11 is disposed along the X direction through the recessed hole, which serves to position the lock cylinder 2 while ensuring that the lock cylinder 2 can rotate along the XZ plane.

[0053] A first abutment 32 is also provided on the connection base 31, and a protrusion 21 is provided on the Y-direction end of the lock core 2. The lock core 2 is cylindrical, and the protrusion 21 is semi-cylindrical. One end of the circumferential side of the protrusion 21 contacts the first abutment 32, and an inclined angle is formed between the protrusion 21 and the first abutment 32. When pressure is applied to the connection base 31, causing the connection base 31 to rotate along the YZ plane, the first abutment 32 pushes the circumferential end of the protrusion 21, causing the protrusion 21 to rotate along the circumferential direction (i.e., along the XZ plane), thereby driving the lock core 2 to rotate along the XZ plane, thereby opening the door handle.

[0054] Furthermore, the reset member 4 is a torsion spring, one end of which is connected to the housing 1 and the other end is connected to the connection base 31. When the connection base 31 is rotated under force, the torsion spring expands. When the pressure on the connection base 31 is no longer applied, the torsion spring contracts to cause the connection base 31 to rotate in the opposite direction, thereby achieving automatic reset of the connection base 31.

[0055] It is worth noting that the lock cylinder 2 of this door handle is reset in the existing technology. When the door handle is installed on the door for use, the lock cylinder 2 will be connected with the conventional door handle installed on the other side of the door to jointly control the extension and retraction of the lock tongue. Therefore, the reset of the lock cylinder 2 of this door handle is controlled by the door handle installed on the other side of the door, and will not be described in detail in this utility model.

[0056] To sum up, when the door handle is installed on the door and used, the user pushes the control component 3 to rotate along the YZ plane toward the door surface to drive the lock core 2 in the shell 1 to rotate along the XZ plane to open the door handle. There is no need to rotate the handle 34 to control the opening of the door handle like a traditional door handle. Even when the hand is inconvenient, the door lock can be easily opened, which is more convenient and practical.

[0057] Example 2:

[0058] This embodiment provides a door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] Furthermore, the control component 3 also includes:

[0060] A second abutting member 33 , the second abutting member 33 being mounted on the connecting seat 31 ;

[0061] The lock core 2 also includes:

[0062] The groove 22, the second abutment member 33 is located in the groove 22 and abuts against one end of the groove 22;

[0063] When the connecting seat 31 rotates along the YZ plane, the second abutting member 33 pushes the lock core 2 to rotate along the XZ plane.

[0064] In this technical solution, a second abutment 33 is also mounted on the connecting base 31. A groove 22 is defined in the lock core 2. The second abutment 33 passes through the lock core 2 and is positioned within the groove 22. A certain angle is formed between the second abutment 33 and the bottom of the groove 22, and the second abutment 33 abuts one end of the groove bottom. When the connecting base 31 rotates along the YZ plane, the angle between the second abutment 33 and the bottom of the groove 22 gradually decreases, and the second abutment 33 pushes the lock core 2 to rotate along the XZ plane, thereby opening the door handle.

[0065] Through this structural design, the door handle can also be opened by utilizing the connection between the second abutment 33 and the groove 22 of the lock core 2, effectively improving the redundancy of the door handle and preventing damage to the first abutment 32 or the protrusion 21 from affecting the use of the door handle.

[0066] Example 3:

[0067] This embodiment provides a door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] Furthermore, the control component 3 also includes:

[0069] The handle 34 is mounted on the connecting seat 31 .

[0070] Furthermore, the handle 34 is an arc-shaped structure.

[0071] In this technical solution, the handle 34 is provided to make the rotation of the connecting seat 31 more convenient and labor-saving, and the handle 34 is designed to be an arc-shaped structure, which can provide a better grip, reduce hand force and fatigue, and effectively improve user comfort.

[0072] It is worth mentioning that the door handle can be used as follows Figure 4 As shown, an auxiliary rotation mechanism 5 is installed on one side of the door handle along the X direction. The structure of the auxiliary rotation mechanism 5 is the same as that of the door handle, with the only difference being that the lock cylinder 2 is not installed inside. Then, a connecting rod 6 is provided to link the door handle and the auxiliary rotation mechanism 5. Through the above structural design, the door handle can be adapted for installation on some large-sized doors for use, ensuring that the proportions of the door handle and the door are more coordinated and improving the overall visual effect. In addition, this structural design can also increase the area of ​​the door handle handle 34 for the user to hold or touch, allowing the user to open the door more quickly and accurately. This is especially helpful in dim light or when the hand is inconvenient to operate (such as when the hand is holding something or there is an obstacle), which can help to open the door more easily and is highly practical.

[0073] Example 4:

[0074] This embodiment provides a door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] Furthermore, the housing 1 further includes:

[0076] A limiting member 35 is installed in the housing 1 and passes through the connecting seat 31 along the X direction;

[0077] The limiting member 35 is used to limit the connection seat 31 from rotating along the YZ plane.

[0078] In this technical solution, two limit holes are opened on the connecting seat 31, and the limit member 35 is installed on the shell 1 and is set through the two limit holes. When the connecting seat 31 rotates a specified angle, the limit member 35 will abut against the hole wall of the limit hole, thereby limiting the further rotation of the connecting seat 31 and improving the structural stability.

[0079] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
