[0007] The lock core is engaged with the handle seat by pressing, and the lock core is axially limited with the lock body and locks the handle body in a locked state. The elastic component applies a first force to pop the lock core out of the locked state and a second force to actuate the lock core to rotate to an initial position.
[0008] Furthermore, the lock core is flush with the surface of the handle body in a locked state, and is located outside the surface of the handle body in an unlocked state.
[0009] Furthermore, in the locked state, the lock core is actuated to rotate from the initial position to disengage from the axial limit of the lock body, and is switched to the unlocked state under the action of the elastic component.
[0010] Furthermore, the lock core has a lock rod extending from the lock body, the handle seat is provided with lock holes corresponding to different rotation positions of the handle body, and the lock core is located on one side of the rotation axis of the handle body.
[0011] Furthermore, the elastic component includes a first elastic member, which abuts between the lock core and the lock body and provides an action tendency for the lock core to pop out of the lock body.
[0012] Furthermore, the elastic component includes a second elastic member, which is fixed on the lock core in the circumferential direction. The second elastic member has a limiting end abutting against the lock body. The free end of the second elastic member rotates with the lock core and applies a torque to keep the lock core in an initial position.
[0013] Furthermore, a track groove is provided on the wall surface of the lock body, and locking parts corresponding to the lock core in the locked state and the unlocked state are provided at both ends of the track groove, and an extension part axially limited with the locking part is provided on the lock core.

[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0018] The utility model provides an elastic component on the handle body, so that in the locked state, the lock core is in a state of being pressed in relative to the handle body, and the handle body cannot be rotated at this time. When it is necessary to perform an unlocking action, it is only necessary to insert the key and then rotate it. In the unlocked state, the lock core is driven by the elastic component to pop out relative to the handle body, so that when locking the door and window handle, it is only necessary to press the lock core to the locked position, thereby realizing keyless locking of the door and window. Moreover, in the unlocked state and the locked state, the lock core is also driven by the elastic component to be circumferentially maintained in the initial position, so that it returns to the initial position again after the key performs the unlocking action, and there is no need to adjust the circumferential position of the lock core, thereby ensuring that the lock core can be smoothly pressed in in the pop-up state, and for the lock core after the unlocking action is completed, the key on it can also be smoothly pulled out.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.
[0031] like Figure 1-9As shown, a door and window handle capable of pressing a lock cylinder 4 comprises a fixedly arranged handle base 1, a handle body 2 rotatably arranged on the handle base 1, and a locking assembly arranged in the handle body 2, wherein the handle body 2 rotates around its own rotation axis, and the locking assembly is arranged on one side parallel to the rotation axis of the handle body 2;
[0032] The locking assembly includes a lock body 3 fixed in the handle body 2, and a lock core 4 inserted in the lock body 3, and an elastic component is also supported on the lock core 4; the lock core 4 has a locked state and an unlocked state popped out relative to the handle body 2, the lock core 4 is further pressed axially relative to the unlocked state in the locked state, and the lock core 4 is constrained in an initial position under the action of the circumferential rotational torque of the elastic component in both the locked state and the unlocked state, and the initial position corresponds to the circumferential limit of the lock core 4 relative to the lock body 3, preferably deviates from the circumferential direction of the lock core 4 in the unlocked state, and corresponds to the vertical insertion direction of the key.
[0033] like Figure 6 As shown, in the unlocked state, the lock core 4 pops out from the surface of the handle body 2. When locking is required, the lock core 4 is pressed to force the lock core 4 to engage with the handle base 1, and the lock core 4 is axially limited with the lock body 3 and locks the handle body 2 in the locked state. The elastic component applies a first force to pop the lock core 4 out of the locked state, and a second force to actuate the lock core 4 to rotate to the initial position.
[0034] The elastic component specifically refers to a first elastic member 5 capable of applying a first axial force to the lock core 4 , and a second elastic member 6 capable of generating a second axial resetting force when deflected from an initial position in the circumferential direction.
[0035] like Figure 1 and Figure 2 As shown, specifically, the lock core 4 is flush with the surface of the handle body 2 in the locked state, so that the lock core 4 cannot be unlocked without a key in the locked state, and the surface end of the lock core 4 is unlocked in the locked state by inserting the key. After the key completes the rotation action, the lock core 4 rotates to the initial position under the action of the reset rotational torque, and rebounds under the axial force, so that the lock core 4 is located on the outside of the surface of the handle body 2 under the action of the elastic component in the unlocked state, and is located at the initial position of the circumferential limit.
[0036] Specifically, the lock core 4 has a lock rod 4.1 extending from the lock body 3, and a button portion located away from the lock rod 4.1, and the handle base 1 is provided with lock holes 1.1 corresponding to different rotation positions of the handle body 2, and the lock core 4 is located on one side of the rotation axis of the handle body 2, wherein the lock holes 1.1 are arranged on both sides of the rotation axis, and the lock core 4 is configured to enter a locked state by a pressing action, at which time the lock rod 4.1 of the lock core 4 is placed in the lock hole 1.1 to prevent the handle body 2 from rotating.
[0037] like Figures 4 to 7 As shown, as a further explanation of the lock core 4 switching from the locked state to the unlocked state, in the locked state, the lock core 4 is driven by the key to rotate from the initial position to disengage the axial limit of the lock body 3, and switches to the unlocked state under the first force and the second force of the elastic component.
[0038] Specifically, the elastic component includes a first elastic member 5 , which applies a first axial force to the lock core 4 , abuts between the lock core 4 and the lock body 3 , and provides a movement tendency for the lock core 4 to pop out of the lock body 3 .
[0039] Among them, the lock core 4 is inserted into the lock body 3, and oppositely arranged step portions are provided on the interior of the lock body 3 and the axial surface of the lock core 4. The first elastic member 5 specifically abuts against the two opposite step portions, and the first elastic member 5 is sleeved on the lock core 4 in the form of a spring, and when the lock core 4 is pressed from the unlocked state, the resistance of the first elastic member 5 needs to be overcome.
[0040] Specifically, the elastic component includes a second elastic member 6, which is fixed on the lock core 4 in the circumferential direction. The second elastic member 6 has a limiting end 6.2 abutting against the lock body 3, and a free end 6.1 rotating with the lock core 4. The torque for keeping the lock core 4 in the initial position is provided by changing the relative distance between the free end 6.1 and the limiting end 6.2.
[0041] The rotation of the free end 6.1 is achieved by driving the lock core 4 with a key, and the free end 6.1 is synchronously driven to rotate when the lock core 4 rotates. Therefore, the initial distance between the free end 6.1 and the limit end 6.2 on the lock core 4 corresponds to the initial position of the lock core 4.
[0042] Of course, the second elastic member 6 can be installed in the lock core 4 in a deformed state.
[0043] In this embodiment, in order to achieve the locking state by directly pressing the lock cylinder 4 in the absence of a key, a guide edge 3.4 is further provided on the lock cylinder 4 corresponding to the stroke from the unlocking state to the locking state. The guide edge 3.4 gradually expands outward during the pressing process, thereby guiding the lock cylinder 4 to the limited position of the locking state. After passing the outer edge of the guide edge 3.4, it is reset and rotated under the action of the second elastic member 6 and re-enters the initial position of the circumferential limit. At the same time, the lock cylinder 4 is limited at the axial boundary of the guide edge 3.4 and is prevented from axial rebound.
[0044] like Figures 3 to 7As shown, as a further implementation method for axially limiting and switching the lock core 4 on the lock body 3, specifically, a track groove 3.1 is provided on the wall surface of the lock body 3, and locking parts corresponding to the lock core 4 in the locked state and the unlocked state are provided at both ends of the track groove 3.1, and an extension part axially limited to the locking part is provided on the lock core 4. For the convenience of distinction, the locking part is divided into a first locking part 3.2 corresponding to the unlocked state and a second locking part 3.3 corresponding to the locked state.
[0045] The extension portion may be a convex portion extending radially on the lock core 4 and located in the track groove 3.1, or may be the free end 6.1 of the second elastic member 6. The extension portion moves from the first locking portion 3.2 to the second locking portion 3.3 by pressing, and returns from the second locking portion 3.3 to the first locking portion 3.2 by rotating the key and the action of the elastic component.
[0046] Furthermore, the first locking portion 3.2 is flush with the second locking portion 3.3 in the circumferential direction, so that the lock core 4 can be positioned at the same circumferential initial position in both the locked state and the unlocked state.
[0047] In the following embodiments, the extension portion is preferably the free end 6 . 1 of the second elastic member 6 .
[0048] Specifically, the guide edge 3.4 is specifically arranged on the track groove 3.1 between the first locking part 3.2 and the second locking part 3.3, and the guide edge 3.4 is arranged obliquely, one end of the guide edge 3.4 is connected to the first locking part 3.2, and the other end is radially spaced from the second locking part 3.3, and the extension part rotates circumferentially under the action of the elastic component and abuts against the locking part.
[0049] Specifically, the lock body 3 is provided with a stop edge 4.3 that abuts against the limiting end 6.2 of the second elastic member 6 in the circumferential direction, the free end 6.1 of the second elastic member 6 constitutes an extension of the lock body 3 and is limited with the locking portion, and the end of the guide edge 3.4 is provided with a limiting edge, which constitutes part of the second locking portion 3.3.
[0050] In the unlocked state, the extension part is limited in the circumferential and axial directions to abut against the first locking part 3.2, and the lock core 4 is limited in the circumferential direction to the initial position by the first locking part 3.2, and at this time, part of the lock core 4 pops out of the handle body 2;
[0051] When locking is required, the pop-up part of the lock core 4 is pressed, and the extension part moves from one end of the guide edge 3.4 toward the other end. At this time, the lock core 4 moves axially, the first elastic member 5 is compressed, and the free end 6.1 of the second elastic member 6 gradually moves in the circumferential direction and compresses the spacing with the limiting end 6.2. When the free end 6.1 moves and is about to leave the end of the guide edge 3.4, the free end 6.1 of the second elastic member 6 is reset in the circumferential direction and drives the lock core 4 to rotate, so that the extension part is limited at the second locking position 3.3. At this time, the end of the lock core 4 is inserted into the lock hole 1.1. At the same time, the lock core 4 is axially abutted against the end of the guide edge 3.4 under the action of the first elastic member 5, so as to maintain the axial locking position. At this time, the lock core 4 is fully pressed in and is located at the initial position in the circumferential direction;
[0052] When it is necessary to unlock, insert the key into the lock core 4 flush with the handle body 2 and turn it, the free end 6.1 of the second elastic member 6 swings out from the second locking position 3.3, and the first elastic member 5 drives the lock core 4 to move axially in the free space between the guide edge 3.4 and the track groove 3.1, and the free end 6.1 abuts against the guide edge 3.4 again under the action of the circumferential restoring force, and gradually returns to the first locking position 3.2 along the guide edge 3.4, at this time the lock core 4 is ejected and is in the initial position in the circumferential direction, at this time the lock rod 4.1 of the lock core 4 leaves the lock hole 1.1, allowing the handle body 2 to rotate.
[0053] Thus, the keyless locking of the handle body 2 can be achieved through a simple pressing operation, and the lock core 4 returns to the initial circumferential position after unlocking and locking.
[0054] from Figure 4 It can be seen that in the above embodiment, the lock core 4 is provided with a radially open receiving groove 4.4, the second elastic member 6 is accommodated in the receiving groove 4.4, and both ends of the second elastic member 6 extend out of the receiving groove 4.4.
[0055] The second elastic member 6 is preferably a sheet-shaped U-shaped retaining spring, the two ends of which constitute a free end 6.1 and a limiting end 6.2, and the U-shaped portion of the retaining spring is placed in the receiving groove 4.4.
[0056] like Figure 8 As shown, in other embodiments, in order to limit the one-way rotation of the lock cylinder 4 to unlock, a radially protruding limiting protrusion 4.5 is further provided on the lock cylinder 4, and a rotation groove 3.5 for the limiting protrusion 4.5 to rotate therein is provided on the lock body 3. In the unlocked state, the limiting protrusion 4.5 abuts against the rotation groove 3.5 under the action of the elastic component, and when the unlocking action of the key is in place, the limiting protrusion 4.5 abuts against the other groove wall of the rotation groove 3.5.
[0057] In the utility model, an elastic component is arranged on the handle body 2. In the locked state, the lock core 4 is in a state of being pressed in relative to the handle body 2. At this time, the handle body 2 cannot be rotated. When it is necessary to perform an unlocking action, it is only necessary to insert the key and then rotate it. In the unlocked state, the lock core 4 is driven by the elastic component to pop out relative to the handle body 2, so that when locking the door and window handle, it is only necessary to press the lock core 4 to the locked position, thereby realizing keyless locking of the door and window. In the unlocked state and the locked state, the lock core 4 is also driven by the elastic component to be circumferentially maintained in the initial position, so that it returns to the initial position again after the key performs the unlocking action, and there is no need to adjust the circumferential position of the lock core 4, thereby ensuring that the lock core 4 can be smoothly pressed in in the pop-up state, and for the lock core 4 after the unlocking action is completed, the key on it can also be smoothly pulled out.
[0058] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
