Description

Technical Field

[0001] The present application relates to the technical field of door locks, and in particular to a door lock handle and a door lock. Background Art

[0002] At present, anti-theft doors on the market usually have peepholes, through which users can observe the situation outside the door. However, when the peephole is damaged, criminals can insert tools such as wire through the peephole to hook the door handle and turn the handle to quickly open the door, endangering the user's personal and property safety.

[0003] To this end, a peephole-proof opening mechanism is installed on the door lock handle. Existing peephole-proof opening mechanisms usually have a cylindrical button on the side of the door lock handle facing away from the door body. To open the door indoors, the thumb is required to press the raised cylindrical button on the door lock handle. Rotating the handle controls the lock body, and simultaneously rotating the door lock handle opens the door. However, while the peephole-proof opening mechanism increases the security of the door lock, it also increases the amount of movement required to open the door, reducing its convenience and ruining the overall aesthetics of the handle's front surface. Utility Model Content

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a door lock handle and a door lock.

[0005] A first aspect of the present application provides a door lock handle, comprising:

[0013] When the first end of the push rocker is pressed, the limiting protrusion is inserted into the limiting groove, and the second end of the push rocker is limitedly engaged with the handle joint; when the first end of the push rocker is released from the pressing, the limiting protrusion is disengaged from the limiting groove, and the second end of the push rocker is disengaged from the handle joint.

[0014] In some embodiments, an anti-rotation protrusion is formed on the end of the limiting protrusion toward the mounting channel, the shape of the limiting groove is adapted to the shape of the anti-rotation protrusion, the anti-rotation protrusion is inserted into the limiting groove, and the anti-rotation protrusion abuts against the side wall of the limiting groove to limit the rotation of the handle body relative to the handle joint.

[0015] In some embodiments, the push rocker is extended along the length direction of the handle portion, and along the extension direction of the push rocker, a movable space is formed between the limiting groove and the anti-rotation protrusion so that the anti-rotation protrusion can be inserted into the limiting groove.

[0016] In some embodiments, the side of the handle portion facing away from the rotating shaft portion is recessed to form a mounting groove, the notch of the mounting groove is covered and connected with a cover plate, and the cover plate and the mounting groove together form the mounting cavity;

[0017] The pressing rocker is rotatably arranged in the mounting groove, and a connecting port connected to the mounting channel is formed at the bottom of the mounting groove. The second end of the pressing rocker is arranged opposite to the connecting port. When the limiting protrusion is inserted into the limiting groove, the limiting protrusion abuts against the periphery of the connecting port.

[0018] In some embodiments, an elastic member is provided in the mounting cavity, and the elastic member is supported between the first end of the push rocker and the inner wall of the mounting cavity. The first end of the push rocker protrudes from the outside of the handle body under the elastic force of the elastic member.

[0019] In some embodiments, the rotating shaft portion is provided at one end portion of the handle portion along the length direction, and the mounting opening is provided at the middle portion of the handle portion along the length direction.

DETAILED DESCRIPTION

[0042] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0044] Reference Figures 1 to 17 As shown, an embodiment of the present application provides a door lock handle, including a handle body 1, a handle joint 3 and a push rocker 2.

[0045] Among them, the handle body 1 includes a handle portion 11 and a rotating shaft portion 12 connected to the handle portion 11. The rotating shaft portion 12 is rotatably connected to the panel 4 of the door lock. An installation channel 121 is provided inside the rotating shaft portion 12, and an installation cavity 13 connected to the installation channel 121 is provided inside the handle portion 11. An installation opening 15 connected to the installation cavity 13 is provided on the handle portion 11. The installation opening 15 and the rotating shaft portion 12 are located on the same side of the handle portion 11.

[0046] In a specific implementation, when the door lock handle is installed on the door body, the rotating shaft portion 12 of the door lock handle is located on the side of the handle portion 11 facing the door body, and the installation opening 15 on the handle portion 11 is also located on the side of the handle portion 11 facing the door body.

[0047] The handle joint 3 is partially rotatably arranged in the installation channel 121, and the handle joint 3 is used to be connected to the transmission shaft of the lock body; the pressing rocker 2 is rotatably arranged in the installation cavity 13, and has a first end 21 and a second end 22 relative to each other. The first end 21 of the pressing rocker 2 protrudes from the outside of the handle body 1 through the installation opening 15, and the second end 22 of the pressing rocker 2 is used to limit or disengage with the handle joint 3 in the rotation direction of the handle body 1.

[0048] Specifically, the handle portion 11 can be selected to be a rectangular or cylindrical structure. The handle portion 11 extends in one direction. The shaft portion 12 is protruded on the handle portion 11. The shaft portion 12 is perpendicular to the extension direction of the handle portion 11. A mounting hole can be optionally provided on the panel 4 of the door lock. The shaft portion 12 is rotatably inserted into the mounting hole, so that the user holds the handle portion 11 with his hand and applies a force in the direction around the shaft portion 12, so that the handle portion 11 drives the shaft portion 12 to rotate relative to the panel 4.

[0049] The interior of the above-mentioned handle portion 11 is hollow, so that the space inside the handle portion 11 serves as the installation cavity 13. A installation channel 121 is provided inside the rotating shaft portion 12 and passes through the rotating shaft portion 12. The installation channel 121 is communicated with the installation cavity 13. A bearing can be optionally provided in the installation channel 121, and the outer ring of the bearing is connected to the inner wall of the installation channel 121. The handle joint 3 is rotatably connected to the inner ring of the bearing.

[0050] Of course, you can also choose to have an annular groove on the inner wall of the installation channel 121, and an annular protrusion on the outer side of the handle joint 3, which is movably set in the annular groove so that the handle joint 3 can rotate in the installation channel 121.

[0051] After the handle connector 3 is connected to the second end 22 of the push rocker 2, relative movement between the handle connector 3 and the push rocker 2 is restricted. At this time, when the handle portion 11 is rotated about the rotation axis 12, the handle body 1 drives the handle connector 3 to rotate, allowing the handle connector 3 to drive the transmission shaft 5 of the lock body to control the opening and closing of the lock body. When the second end 22 is disengaged from the handle connector 3, the handle connector 3 rotates relative to the panel 4, while the handle connector 3 does not rotate. When a wire is inserted through the peephole into the inside of the door and hooked to the handle portion 11 and rotated, the door lock body will not open, thus preventing the peephole from unlocking the door.

[0052] The above-mentioned push rocker 2 can be selected as a straight plate, and a rotating shaft is set in the middle of the push rocker 2, and the rotating shaft is rotatably connected to the inner wall of the mounting cavity 13. The push rocker 2 is set between the mounting opening 15 and the rotating shaft part 12, and the first end 21 is set opposite to the mounting opening 15, and the second end 22 extends to the mounting channel 121 and is set opposite to the handle joint 3.

[0053] A raised structure may be optionally provided on the above-mentioned second end portion 22, and a groove may be provided on the end surface of the handle joint 3 facing the second end portion 22, and the raised structure is arranged opposite to the groove on the end surface of the handle joint 3 in the mounting channel 121; when the first end portion 21 is exposed outside the mounting opening 15, the second end portion 22 and the handle joint 3 are spaced apart from each other, so that the second end portion 22 and the handle joint 3 are separated from each other; when the first end portion 21 is pressurized and rotates along the rotating shaft portion 12 toward the handle portion 11, the second end portion 22 rotates along the handle portion 11 toward the rotating shaft portion 12, so that the raised structure on the second end portion 22 is inserted into the groove of the handle joint 3, so that the raised structure of the second end portion 22 abuts against the side wall of the groove, so that when the handle body 1 rotates relative to the panel 4, the abutment of the raised structure with the side wall of the groove drives the handle joint 3 to rotate together with the handle body 1, so as to realize the limiting cooperation between the second end portion 22 and the handle joint 3.

[0054] The above-mentioned second end 22 can also be optionally provided with a groove on the side facing the handle joint 3, and a protrusion is provided on one end of the handle joint 3 facing the second end 22. When the first end 21 is exposed outside the mounting opening 15, the groove of the second end 22 and the protrusion of the handle joint 3 are isolated from each other and arranged relative to each other, so that the second end 22 and the handle joint 3 are disengaged from each other; when the first end 21 is pressurized and rotates along the direction of the rotating shaft portion 12 toward the handle portion 11, the second end 22 rotates along the direction of the handle portion 11 toward the rotating shaft portion 12, and the protrusion on the handle joint 3 is inserted into the groove on the second end 22, and the protrusion abuts against the side wall of the groove, so that when the handle body 1 rotates relative to the panel 4, the abutment between the protrusion and the side wall of the groove drives the handle joint 3 to rotate together with the handle body 1, so as to realize the limited cooperation between the second end 22 and the handle joint 3.

[0055] The above-mentioned handle joint 3 is connected to the transmission shaft 5 of the door lock, so that the handle joint 3 can rotate to drive the transmission shaft 5 of the door lock to control the opening or closing of the lock body of the door lock; when the door lock handle is installed on the door, the position of the handle part 11 set in the horizontal direction can be selected as the initial position. In the initial position, the raised structure on the second end 22 matches the groove shape of the handle joint 3, so that when the second end 22 is rotated toward the handle joint 3, the raised structure can be smoothly inserted into the groove.

[0056] When the door lock handle provided by the present application is used, the handle joint 3 is connected to the transmission shaft of the lock body, the first end 21 is exposed on the outside of the handle part 11 through the installation opening 15, the door lock is installed on the door, and the shaft part 12 is rotatably installed on the panel 4 of the door lock; when the user needs to open the door, he holds the handle part 11 with his hand, and while holding the handle part 11, applies pressure to the first end 21 exposed on the outside of the handle part 11, so that the first end 21 rotates along the shaft part 12 toward the handle part 11, thereby connecting the second end 22 to the handle joint 3. At this time, the handle part 11 is driven to drive the shaft part 12 to rotate relative to the panel 4, and the handle joint 3 rotates together with the handle part 11 and the shaft part 12, so that the handle joint 3 controls the opening and closing of the door lock through the transmission shaft.

[0057] When the first end 21 is exposed on the outside of the handle portion 11, the second end 22 is disengaged from the handle joint 3. When the handle body 1 is rotated, the handle joint 3 rotates relative to the handle body 1, so that the rotation of the handle body 1 will not drive the handle joint 3 to rotate. When a wire or an iron hook is used to extend through the peephole into the inside of the door, and the wire is hooked to the handle portion 11 to drive the handle portion 11 to drive the rotating shaft portion 12 to rotate, the rotation of the handle body 1 cannot drive the handle joint 3 to rotate, thereby preventing the peephole from unlocking.

[0058] The door lock handle provided by the present application is provided with a push-on rocker 2 rotatably arranged in the mounting cavity 13 of the handle portion 11, and a handle joint 3 rotatably arranged in the mounting channel 121 of the shaft portion 12, so that the first end 21 of the push-on rocker 2 is exposed outside the mounting opening 15, and the second end 22 of the push-on rocker 2 is disengaged from the handle joint 3. At this time, rotating the handle body 1 will not drive the handle joint 3 to rotate, preventing the use of wire or iron hook to drive the handle portion 11 to rotate and open the door lock; when the user needs to open or lock the door, due to the push-on rocker 2 The first end 21 and the rotating shaft portion 12 are located on the same side of the handle portion 11, that is, the first end 21 of the push rocker 2 is located on the side of the handle body 1 facing the door body. When the user holds the handle portion 11, he can press the first end 21. Under the force of the pressure, the first end 21 drives the push rocker 2 to rotate, so that the second end 22 rotates toward the handle joint 3 and cooperates with the handle joint limit. At this time, rotating the handle body 1 can drive the handle joint 3 to rotate together, so that the handle joint 3 drives the transmission shaft 5 of the lock body to rotate to control the unlocking of the lock body. With this arrangement, when opening the door, the user does not need to use his thumb to press the button on the door lock handle and then turn the handle, which simplifies the action required to open the door and improves the convenience of opening the door. In addition, because the first end of the push rocker protrudes from the side of the handle body facing the door body through the installation opening, the overall aesthetics of the front of the door lock handle is improved.

[0059] Reference Figure 2 、 Figure 3 、 Figure 6 and Figure 9As shown, in some embodiments, the push-on rocker 2 extends along the mounting opening 15 toward the rotation axis 12, and a rotation axis 23 is provided in the middle portion of the push-on rocker 2 along the extension direction. The rotation axis 23 is rotatably connected to the inner wall of the mounting cavity 13, and the first end 21 and the second end 22 of the push-on rocker 2 rotate about the rotation axis 23. With this arrangement, the rotation axis is provided in the middle portion of the push-on rocker 2, so that when the second end 22 is pressed and moved, the first end 21 can synchronously rotate about the rotation axis 23. The user can connect the second end 22 to the handle joint 3 by pressing the first end 21, simplifying the operation convenience of the limited engagement between the push-on rocker 2 and the handle joint 3.

[0060] Specifically, the push rocker 2 can be selected as a straight plate, which extends along the mounting opening 15 toward the direction of the rotating shaft portion 12, and the two ends of the straight plate are respectively a first end 21 and a second end 22, and the rotating shaft 23 is set in the middle of the push rocker 2. The distance between the rotating shaft 23 and the first end 21 and the second end 22 can be selected to be equal in the extension direction of the push rocker 2. Of course, the distance between the rotating shaft 23 and the first end 21 can also be selected to be greater than or less than the distance between the rotating shaft 23 and the second end 22. As long as the first end 21 and the second end 22 are respectively on both sides of the rotating shaft 23, when the push rocker 2 rotates, the first end 21 and the second end 22 rotate synchronously around the rotating shaft 23, so that when the second end 22 rotates along the direction of the rotating shaft portion 12 toward the handle portion 11, the first end 21 rotates synchronously along the handle portion 11 toward the rotating shaft portion 12.

[0061] The direction of the mounting opening 15 toward the rotation axis 12 corresponds to the length direction of the handle portion 11. The direction in which the handle portion 11 rotates about the rotation axis 12 corresponds to the height direction of the handle portion 11. The rotation axis 23 is disposed along the height direction of the handle portion 11 and is rotatably connected to the interior of the mounting cavity 13. When the first end portion 21 is compressed and rotates toward the rotation axis 12 toward the handle portion 11, the second end portion 22 simultaneously rotates in the direction of the handle portion 11 toward the rotation axis 12, allowing the second end portion 22 to move toward the mounting channel 121, thereby connecting the second end portion 22 to the handle joint 3.

[0062] The above-mentioned mounting cavity 13 is provided with a rotating groove 16 on the inner wall on one side along the height direction of the handle portion 11. The rotating groove 16 is recessed along the height direction of the handle portion 11. The rotating shaft 23 is movably plugged into the rotating groove 16, so that the rotating shaft 23 is rotatably connected to the inner wall of the mounting cavity 13; the number of rotating grooves 16 can be selected as two, and the two rotating grooves 16 are respectively provided on the inner walls on both sides opposite to each other in the height direction of the handle portion 11, and the two ends of the rotating shaft 23 are rotatably connected to the two rotating grooves 16 respectively.

[0063] Reference Figures 6 to 11As shown, in some embodiments, the second end 22 of the rocker 2 is pressed to form a limiting protrusion 221 extending toward the installation channel 121, and the handle joint 3 is provided with a limiting groove 31 corresponding to the limiting protrusion 221; when the first end 21 of the rocker 2 is pressed, the limiting protrusion 221 is inserted into the limiting groove 31, and the second end 22 of the rocker 2 is limitedly engaged with the handle joint 3; when the first end 21 of the rocker 2 is released from the pressure, the limiting protrusion 221 is disengaged from the limiting groove 31, and the second end 22 of the rocker 2 is disengaged from the handle joint 3.

[0064] With such arrangement, the limiting protrusion 221 extends toward the installation channel 121, shortening the distance that the second end portion 22 needs to move when the limiting protrusion 221 is inserted into the limiting groove 31, thereby facilitating the plug-in connection between the limiting protrusion 221 and the limiting groove 31; the limiting protrusion 221 and the limiting groove 31 have a simple structure, and the limiting protrusion 221 and the limiting groove 31 can be plugged in and out of the limiting groove 31 by pressing the rocker 2 to rotate around the rotating shaft 23; the plug-in connection between the limiting protrusion 221 and the limiting groove 31 is stable, and the effect of transmitting the force through the abutment between the limiting protrusion 221 and the limiting groove 31 is stable.

[0065] Specifically, a block-shaped protrusion is provided on the side of the second end portion 22 facing the installation channel 121 as a limiting protrusion 221, so that the limiting protrusion 221 and the pressing rocker 2 form an "L"-shaped structural component; the limiting protrusion 221 is inserted into the limiting groove 31, so that the limiting protrusion 221 abuts against the side wall of the limiting groove 31, so that the force of the handle body 1 driving the pressing rocker 2 can be transmitted to the handle joint 3, so that the handle joint 3 rotates together with the handle body 1.

[0066] In the extension direction perpendicular to the pressing rocker 2, the size of the limiting groove 31 can be selected to be larger than the limiting protrusion 221, so that when the limiting protrusion 221 is in the limiting groove 31, the handle body 1 drives the limiting protrusion 221 to rotate, and the limiting protrusion 221 moves in the limiting groove 31. The limiting protrusion 221 will move to a position abutting against the side wall of the limiting groove 31. The limiting protrusion 221 can be selected to abut against the side wall of the limiting groove 31 in the direction in which the handle part 11 rotates around the rotating shaft part 12. The force of the rotation of the handle body 1 is transmitted to the handle joint 3 through the abutment between the limiting protrusion 221 and the limiting groove 31, so that the handle joint 3 rotates together with the limiting protrusion 221.

[0067] In the extension direction perpendicular to the push rocker 2, the size of the limiting groove 31 can be selected to be equal to the limiting protrusion 221, so that after the limiting protrusion 221 is inserted into the limiting groove 31, the limiting protrusion 221 will abut against the side walls of the limiting groove 31 on both sides of the extension direction perpendicular to the push rocker 2, so that when the push rocker 2 rotates with the handle body 1, the handle joint 3 rotates synchronously with the push rocker 2.

[0068] When the above-mentioned first end portion 21 is pressed, in the direction of the rotating shaft portion 12 toward the handle portion 11, the first end portion 21 moves in the direction away from the rotating shaft portion 12, and the second end portion 22 simultaneously moves in the direction close to the rotating shaft portion 12, so that the limiting protrusion 221 on the second end portion 22 can be inserted into the limiting groove 31; when the first end portion 21 moves in the direction close to the rotating shaft portion 12, the second end portion 22 will simultaneously move in the direction away from the rotating shaft portion 12, so that the limiting protrusion 221 is disconnected from the limiting groove 31.

[0069] Reference Figures 6 to 11 As shown, in some embodiments, an anti-rotation protrusion 222 is formed on the end of the limiting protrusion 221 facing the installation channel 121. The shape of the limiting groove 31 matches the shape of the anti-rotation protrusion 222. The anti-rotation protrusion 222 is inserted into the limiting groove 31 and abuts against the sidewall of the limiting groove 31 to limit the rotation of the handle body 1 relative to the handle joint 3. In this configuration, the anti-rotation protrusion 222 abuts against the sidewall of the limiting groove 31, allowing the force applied by the rocker plate 2 in the direction of rotation of the handle body 1 to be transmitted to the handle joint 3. When the user presses the first end 21 and rotates the handle body 1, the handle joint 3 can rotate synchronously with the rocker plate 2, facilitating the user's door opening operation.

[0070] Specifically, the anti-rotation protrusion 222 can be selected as a rectangular protrusion or other polygonal protrusion on the limiting protrusion 221, and the shape of the limiting groove 31 matches the anti-rotation protrusion 222. The size of the limiting groove 31 in the extension direction of the pressing rocker 2 can be selected to be larger than the size of the anti-rotation protrusion 222, so that the anti-rotation protrusion 222 can be inserted into the limiting groove 31 as the pressing rocker 2 rotates.

[0071] After the above-mentioned anti-rotation protrusion 222 is inserted into the limiting groove 31, the anti-rotation protrusion 222 abuts against the inner walls on both sides of the limiting groove 31 perpendicular to the extension direction of the pressing rocker 2. Of course, the limiting groove 31 can also be selected to have multiple side walls, and the side walls on both sides of the limiting groove 31 perpendicular to the pressing rocker 2 abut against the anti-rotation protrusion 222, and the side wall of the limiting groove 31 on the side of the extension direction of the pressing rocker 2 abuts against the anti-rotation protrusion 222.

[0072] Reference Figure 3 、 Figures 6 to 11As shown, in some embodiments, a movable space is formed between the limiting groove 31 and the anti-rotation protrusion 222 along the extension direction of the push rocker 2, and the second end portion 22 is rotated toward the handle joint 3 to insert the anti-rotation protrusion 222 into the limiting groove. This arrangement allows the lower anti-rotation protrusion 222 to smoothly insert into the limiting groove 31 when the anti-rotation protrusion 222 makes an arc motion as the push rocker 2 rotates. Furthermore, if the connection between the push rocker 2 and the inner wall of the mounting cavity 13 becomes loose due to long-term use, causing the push rocker 2 to deviate in the extension direction of the push rocker 2, the limiting groove 31 has sufficient space to allow the anti-rotation protrusion 222 to insert into the limiting groove 31 as the push rocker 2 rotates.

[0073] Specifically, the size of the limiting groove 31 along the extension direction of the pressing rocker 2 is larger than the size of the anti-rotation protrusion 222 along the extension direction of the pressing rocker 2. The limiting groove 31 can be selected as a through groove that passes through the handle joint 3 along the extension direction of the pressing rocker 2. Of course, the limiting groove 31 can also be selected to have two opposite groove walls along the extension direction of the pressing rocker 2.

[0074] When the above-mentioned anti-rotation protrusion 222 is inserted into the limiting groove 31, the movable space can be selected to be formed on the side of the anti-rotation protrusion 222 away from the first end 21 along the extension direction of the pressing rocker 2. Of course, the movable space can also be selected to be formed on both sides of the anti-rotation protrusion 222 along the extension direction of the pressing rocker 2.

[0075] Reference Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the side of the handle portion 11 facing away from the rotating shaft portion 12 is recessed to form a mounting groove, and the groove opening of the mounting groove is covered and connected with a cover plate 14, and the cover plate 14 and the mounting groove together form a mounting cavity 13; the mounting opening 15 is connected to the mounting groove and exposed at the bottom of the mounting groove, and the mounting channel 121 is connected to the mounting groove, and a connecting port is formed at the bottom of the mounting groove; the pressing rocker 2 is rotatably arranged in the mounting groove, and the second end 22 is arranged opposite to the connecting port, and when the limiting protrusion 221 is inserted into the limiting groove 31, the limiting protrusion 221 abuts against the edge of the connecting port to limit the second end 22 of the pressing rocker 2 from moving toward the mounting channel 121.

[0076] With such arrangement, the cooperation between the cover plate 14 and the mounting groove facilitates the installation of the push-on rocker 2 in the mounting cavity 13; when the limiting protrusion 221 is inserted into the limiting groove 31, the limiting protrusion 221 abuts against the periphery of the connecting port, preventing the limiting protrusion 221 from continuing to move toward the mounting channel 121 and colliding with the bottom of the limiting groove 31, thereby reducing the wear of the limiting protrusion 221 inserted into the limiting groove 31.

[0077] Specifically, the shape and volume of the cover plate 14 correspond to the notch of the mounting slot, so that the cover plate 14 can cover the notch of the mounting slot, thereby making the cover plate 14 close the notch of the mounting slot, so that the mounting slot forms a mounting cavity 13. When installing the push rocker 2 in the mounting slot, the cover plate 14 is first separated from the handle portion 11. After the push rocker 2 is installed, the cover plate 14 is connected to the handle portion 11, which facilitates the operation of installing the push rocker 2 in the mounting slot.

[0078] The aforementioned mounting channel 121 forms a communication opening at the bottom of the mounting groove. The bottom of the mounting groove can be recessed away from the cover plate 14 to form an abutment groove 122. The communication opening is formed at the bottom of the abutment groove 122. When the limiting protrusion 221 is plugged into the limiting groove 31, the limiting protrusion 221 first enters the abutment groove 122 and then inserts into the limiting groove 31 of the mounting channel 121. After the limiting protrusion 221 is inserted into the limiting groove 31, the position of the limiting protrusion 221 near the first end 21 abuts against the bottom of the abutment groove 122, thereby limiting the limiting protrusion 221 from continuing to move along the handle portion 11 toward the rotating shaft portion 12. Of course, the communication opening can also be provided at the bottom of the mounting groove. After the limiting protrusion 221 is inserted into the limiting groove 31, the limiting protrusion 221 abuts against the bottom of the mounting groove.

[0079] Reference Figure 3 、 Figures 6 to 11 As shown, in some embodiments, an elastic member 24 is disposed within the mounting cavity 13. The elastic member 24 is supported between the first end 21 of the push rocker 2 and the inner wall of the mounting cavity 13. The first end 21 of the push rocker 2 protrudes from the outside of the handle body 1 due to the elastic force of the elastic member 24. With this arrangement, when the user stops pressing the first end 21, the elastic member 24 returns the first end 21 to the position protruding from the outside of the handle body 1, and simultaneously disengages the second end 22 from the handle connector 3. This prevents the door lock handle from being unlocked by a peephole when the user is not gripping the handle 11.

[0080] Specifically, the elastic member 24 can be selected as a spring or an elastic metal sheet. The elastic member 24 is arranged on the side of the first end portion 21 facing away from the rotating shaft portion 12, and one end of the elastic member 24 is connected to the inner wall of the mounting cavity 13 on the side opposite to the mounting opening 15, and the other end is connected to the first end portion 21. The elastic member 24 applies a force to the first end portion 21 along the direction of the handle portion 11 toward the rotating shaft portion 12, so that when the first end portion 21 is not pressed, the first end portion 21 moves along the direction of the handle portion 11 toward the rotating shaft portion 12 under the elastic force of the elastic member 24, thereby keeping the first end portion 21 exposed on the outside of the handle portion 11.

[0081] When the user presses the first end portion 21, the user overcomes the elastic force of the elastic member 24 and can rotate the first end portion 21 along the rotation axis portion 12 toward the handle portion 11, so that the anti-rotation protrusion 222 is plugged into the limiting groove 31; when the user releases the handle portion 11, the user stops applying the pressing force on the first end portion 21, and the first end portion 21 moves along the handle portion 11 toward the rotation axis portion 12 under the action of the elastic force, so that the first end portion 21 protrudes on the outside of the handle portion 11, and the second end portion 22 rotates synchronously to cause the anti-rotation protrusion 222 to disengage from the limiting groove 31.

[0082] When the first end portion 21 is exposed outside the handle body 1 through the mounting opening 15 , the second end portion 22 is disengaged from the handle joint 3 , that is, the anti-rotation protrusion 222 is disengaged from the limiting groove 31 .

[0083] Reference Figure 5 、 Figure 6 and Figure 9 As shown, in some embodiments, the shaft portion 12 and the mounting opening 15 are spaced apart along the length of the handle portion 11, with the shaft portion 12 being located at one end of the handle portion 11 and the mounting opening 15 being located in the middle of the length of the handle portion 11. With this arrangement, when a user grips the handle portion 11, they typically grip the middle portion of the handle portion 11. The mounting opening 15 being located in the middle portion of the handle portion 11 allows the user's index and middle fingers to press the first end portion 21 when gripping the handle portion 11, making it easier for the user to forcefully press the first end portion 21 when gripping the handle portion 11.

[0084] Specifically, the mounting opening 15 is arranged in the middle of the handle portion 11, and the distance between the mounting opening 15 and the rotating shaft portion 12 can be selected to be equal to the distance between the mounting opening 15 and the end of the handle portion 11 away from the rotating shaft portion 12. Of course, the middle of the handle portion 11 can also be selected as a range, and the mounting opening 15 can be within the range. As long as the user grasps the handle portion 11 with his hand, the user's middle finger and index finger are arranged relative to the first end portion 21, so that the user can apply a pressing force to the first end portion 21.

[0085] Reference Figure 6 and Figure 9 As shown, in some embodiments, a button portion 211 is protruded from the first end portion 21 of the push rocker 2. The button portion 211 protrudes from the outside of the handle body 1 through the mounting opening 15. In this configuration, the button portion 211 protrudes from the outside of the handle body 1, allowing the push rocker 2 to remain within the mounting cavity 13, reducing interference from the external environment on the push rocker 2.

[0086] Specifically, the button portion 211 can be a block structure with a rectangular, elliptical or runway-shaped cross-section, and the first end portion 21 can be processed into a raised structure by stamping deformation as the button portion 211; of course, the button portion 211 can also be connected to the side of the first end portion 21 facing the installation opening 15 by welding, bonding or clamping.

[0087] Reference Figures 1 to 17 As shown, an embodiment of the present application also provides a door lock, including a door lock handle as described in any of the above items.

[0088] Specifically, the door lock includes a lock body 6, a panel 4 and the above-mentioned door lock handle. The panel and the lock body are arranged opposite to each other. The lock body 6 is installed inside the door body, and the panel 4 is installed on the outer surface of the door body. The handle part 11 is arranged on the side of the panel 4 facing away from the door body. A mounting hole is provided on the panel 4, and the rotating shaft part 12 is rotatably connected to the mounting hole. A transmission shaft 5 is provided on the lock body 6, and the transmission shaft 5 is connected to the handle joint 3. The mounting opening 15 is arranged toward the panel 4.

[0089] The above-mentioned transmission shaft 5 can be selected as square steel, and an assembly groove 32 is set in a recessed manner at one end of the handle joint 3 facing away from the installation cavity 13. The cross-section of the assembly groove 32 is a rectangle that is compatible with the square steel. After the square steel is inserted into the assembly groove 32, the four side surfaces of the square steel abut against the four side walls of the assembly groove 32, so that the handle joint 3 can drive the square steel to rotate when it rotates.

[0090] The above-mentioned panel 4 can optionally include a front plate 41, a rear cover 42 and a connecting pad 43. The front plate and the rear cover 42 are arranged opposite to each other and spaced apart from each other. The connecting pad 43 is connected between the front plate 41 and the rear cover 42. Through holes are respectively provided on the front plate 41 and the rear cover 42, and the two through holes are coaxially arranged. The rotating shaft portion 12 is rotatably connected to the through hole on the front plate 41, and the handle joint 3 is passed through the through hole of the rear cover 42 to be connected to the transmission shaft 5 of the lock body 6.

[0091] A torsion spring 44 and a turntable 45 can be optionally set between the front plate 41 and the rear cover 42. The turntable 45 is connected to the rotating shaft portion 12. The torsion spring 44 is sleeved on the outside of the rotating shaft portion 12. One end of the torsion spring 44 is connected to the front plate 41, and the other end is connected to the turntable 45. A bolt can be optionally set on the turntable 45, and the bolt is connected to one end of the torsion spring 44.

[0092] When the handle portion 11 is in the initial position, the torsion spring 44 is not deformed and will not drive the turntable 45 to rotate. When the handle portion 11 is subjected to force to drive the shaft portion 12 to rotate relative to the panel 4, the turntable 45 rotates together with the shaft portion 12, thereby deforming the torsion spring 44. After the force on the handle portion 11 stops, the elastic force of the torsion spring 44 drives the turntable 45 to drive the shaft portion 12 to rotate, so that the handle portion 11 returns to the initial position.

[0093] A lock tongue and a lock column 61 are movably provided on the lock body 6. When the lock tongue extends out of the side of the lock body 6, the lock tongue can be plugged into the groove of the door frame to keep the door in a closed state. When the lock column 61 extends out of the side of the lock body 6, the lock column 61 can be inserted into the keyhole on the door frame to lock the door body in the door frame. When the lock body 6 is closed in the door frame, the lock tongue is in a state of extending out of the lock body 6, and the lock column 61 is in a state of retracting into the lock body 6. The drive shaft 5 can be selected to rotate in one direction to retract the lock tongue into the lock body 6, and the drive shaft 5 can be selected to rotate in the other direction to extend the lock column 61 out of the lock body 6.

[0094] When the door lock handle and door lock provided by the embodiments of the present application are used, the panel 4 is mounted on the exterior side of the door, the lock body 6 is mounted inside the door, the rotating shaft 12 is rotatably connected to the panel 4, and the handle connector 3 is connected to the transmission shaft 5 of the lock body 6. The first end 21 is exposed outside the handle portion 11 through the mounting opening 15. The door is closed on the door frame, and the handle portion 11 is in its initial horizontal position.

[0095] like Figure 1 As shown, the handle portion 11 is in an initial position when it is arranged in the horizontal direction. At this time, the lock tongue is in an extended state, and the door body remains closed on the door frame.

[0096] like Figure 12 and Figure 13 As shown, when the user holds the handle portion 11 and presses the button portion 211 of the first end portion 21, the first end portion 21 drives the pressing rocker 2 to rotate around the rotating axis 23 along the direction of the rotating shaft portion 12 toward the handle portion 11, and the second end portion 22 rotates along the direction of the handle portion 11 toward the rotating shaft portion 12, so that the anti-rotation protrusion 222 is inserted into the limiting groove 31. The user keeps pressing the first end portion 21 and presses the handle portion 11 downward, and the handle portion 11 drives the rotating shaft portion 12 and the handle joint 3 to rotate in the clockwise direction, so that the handle joint 3 drives the transmission shaft 5 to rotate in the clockwise direction, so that the lock tongue retracts into the lock body 6.

[0097] like Figure 14 As shown, the first end portion 21 protrudes from the outside of the handle portion 11, so that the anti-rotation protrusion 222 of the second end portion 22 disengages from the limiting groove 31. At this time, the handle portion 11 is pressed downward, and the handle portion 11 drives the rotating shaft portion 12 to rotate clockwise relative to the panel 4. The handle joint 3 remains stable and does not rotate. At this time, the rotation of the handle body 1 will not cause the lock tongue to retract into the lock body 6.

[0098] like Figure 15 and Figure 16As shown, when the user holds the handle portion 11 and presses the button portion 211 of the first end portion 21, the rocker 2 is pressed to rotate around the rotating shaft 23, so that the anti-rotation protrusion 222 of the second end portion 22 is inserted into the limiting groove 31. The user lifts the handle portion 11, and the handle portion 11 drives the rotating shaft portion 12 and the handle joint 3 to rotate in the counterclockwise direction, so that the handle joint 3 drives the transmission shaft 5 to rotate in the counterclockwise direction, so that the lock column 61 is extended and retracted from the lock body 6, so that the door body is locked in the door frame.

[0099] like Figure 17 As shown, the first end portion 21 protrudes from the outside of the handle portion 11, so that the anti-rotation protrusion 222 of the second end portion 22 disengages from the limiting groove 31. At this time, the handle portion 11 is lifted, and the handle portion 11 drives the rotating shaft portion 12 to rotate counterclockwise relative to the panel 4. The handle joint 3 remains stable and does not rotate. At this time, the rotation of the handle body 1 will not cause the lock column 61 to extend out of the lock body 6.

[0100] Some other embodiments of the present invention provide a door lock, comprising a door lock handle as described in any of the above embodiments.
