[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figures 1 to 6 When the handle is unlocked, the handle 1 is unlocked, and the locking member 2 is unlocked, so that the handle 1 is unlocked. When the handle 1 is unlocked, the locking member 2 is unlocked, and the locking member 2 is unlocked. When the handle 1 is unlocked, the locking member 2 is unlocked, and the locking member 2 is unlocked. When the handle 1 is unlocked, the locking member 2 is unlocked, and the locking member 2 is unlocked.

[0030] Specifically, in this embodiment, the first direction can refer to Figure 2 The e1 direction in the second direction can refer to Figure 3 The e2 direction in .

[0031] like Figure 1 and Figure 5 As shown, in addition, this embodiment also provides a lock, which includes the above-mentioned handle assembly, and also includes a lock core 6 and a transmission member 5. The transmission member 5 is connected to the grip shell, and the transmission member 5 can rotate synchronously with the grip shell. The transmission member 5 is also connected to the lock core 6. Driven by the transmission member 5, the lock tongue of the lock core 6 can be extended and retracted to achieve unlocking or opening. The lock has all the advantages of the above-mentioned handle assembly and will not be repeated here.

[0032] The present embodiment provides a handle assembly, which directly arranges an integrally protruding snap-in block 12 in the mounting cavity 11 of the grip 1, and snap-fits the snap-in block 12 to the side wall of the push member 3. This arrangement, on the one hand, not only limits the movement of the push member 3 in the second direction (perpendicular to the sliding direction), but also improves the stability and reliability of the push member 3 during the sliding process. On the other hand, the snap-in block 12 is an integrally protruding design of the side wall of the mounting cavity 11, and can be snap-fitted to the push member 3 without additional processing or installation steps, and there is no need to install additional components such as pressure plates in the mounting cavity 11 to limit the movement of the push member 3, thereby reducing unnecessary parts and simplifying the structure, thereby reducing production costs and assembly difficulty.

[0033] like Figure 4 and Figure 5 As shown, specifically, in this embodiment, the mounting cavity 11 has a first side wall 111. Preferably, the clamping block 12 includes a connecting rib 121 and a hook 122. The connecting rib 121 is connected to the first side wall 111, and the hook 122 is connected to the connecting rib 121. The hook 122 and the first side wall 111 clamp on both sides of the pusher 3 to limit the movement of the pusher 3 in the second direction. In this way, the connecting rib 121 is firmly connected to the first side wall 111 of the mounting cavity 11, and the hook 122 is connected to the connecting rib 121. This design forms a stable clamping space between the hook 122 and the first side wall 111. When the pusher 3 slides along the first direction, the two sides of the pusher 3 are tightly clamped by the hook 122 and the first side wall 111. This clamping method not only accurately positions the pusher 3, but also effectively limits its movement in the second direction, thereby ensuring the stability and reliability of the pusher 3 during the sliding process.

[0034] like Figure 4 and Figure 5As shown, specifically, in this embodiment, an operating port 13 is provided on one side of the holding shell, and a push button portion 33 for user operation is provided on one side of the pushing member 3. The push button portion 33 is slidably provided in the operating port 13 and exposed from the operating port 13, so that the user can drive the pushing member 3 to slide along the first direction by pushing the push button portion 33.

[0035] like Figure 4 and Figure 5 As shown, preferably, in this embodiment, the clamping block 12 further includes a reinforcing rib 123, which is connected between the connecting rib 121 and the first side wall 111. In this way, the reinforcing rib 123 is directly connected between the connecting rib 121 and the first side wall 111, forming an additional supporting structure. This design significantly enhances the structural strength of the clamping block 12 and even the entire mounting cavity 11 of the grip 1. When subjected to external forces, the reinforcing rib 123 can disperse and resist stress, reducing the risk of deformation and damage, thereby improving the durability and safety of the entire lock.

[0036] like Figure 2 、 Figure 4 and Figure 5 As shown, preferably, in this embodiment, the clamping blocks 12 are arranged in pairs, each pair of clamping blocks 12 is arranged opposite to each other, and each pair of clamping blocks 12 is located on both sides of the pusher 3. In this way, the clamping blocks 12 arranged in pairs clamp the pusher 3 from both sides at the same time, forming a more stable support structure. On the one hand, this double clamping not only limits the movement of the pusher 3 in the second direction, but also enhances its sliding stability in the first direction. Even under the action of external force, the pusher 3 can maintain its original position and posture, ensuring the accurate execution of the anti-locking function; on the other hand, because each pair of clamping blocks 12 is located on both sides of the pusher 3, when the pusher 3 is subjected to external force, the force will be evenly distributed to the two clamping blocks 12. This uniform force reduces the problem of local stress concentration, reduces the risk of component damage, and prolongs the service life of the lock; on the other hand, the clamping blocks 12 arranged in pairs provide a more accurate positioning reference for the installation of the pusher 3. During the assembly process, it can ensure that the pusher 3 can be accurately and stably clamped therein, which helps to improve the overall performance and reliability of the lock.

[0037] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, preferably, in this embodiment, the pusher 3 is provided with an insertion port 31, which is provided in pairs, with a pair of insertion ports 31 corresponding to a pair of clamping blocks 12. When the pusher 3 is clamped between the pair of clamping blocks 12, the insertion ports 31 and the clamping blocks 12 can slide together to provide a guide for the installation of the pusher 3. In this way, the sliding fit between the insertion ports 31 and the clamping blocks 12 provides a precise guide for the installation of the pusher 3. During the assembly process, the user only needs to align the insertion ports 31 on the pusher 3 with the clamping blocks 12 and gently push it in to achieve quick and accurate installation of the pusher 3. This design simplifies the installation steps, reduces the installation difficulty, and improves assembly efficiency.

[0038] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, more preferably, in this embodiment, the hook 122 is provided with a first guide bevel 1221, and the plug-in port 31 is provided with a second guide bevel 311; when the pushing member 3 is engaged between a pair of engaging blocks 12, the second guide bevel 311 and the first guide bevel 1221 slide together, and the second guide bevel 311 can push the first guide bevel 1221 to open the pair of engaging blocks 12 to each other. In this way, when the pushing member 3 attempts to engage between a pair of engaging blocks 12, the second guide bevel 311 first contacts and starts to slide with the first guide bevel 1221. This bevel design helps to guide the pushing member 3 to slide smoothly into the engaging position, reducing the resistance and noise caused by direct collision; and, during the sliding engagement process, the second guide bevel 311 can push the first guide bevel 1221, thereby causing the pair of engaging blocks 12 to open each other when subjected to external force. This automatic opening mechanism simplifies the installation process. The user does not need to manually adjust the position or angle of the engaging block 12. The pushing member 3 can be quickly installed by simply pushing it along the guide bevel. In addition, the design of the guide bevel also reduces the direct contact area and friction between the engaging block 12 and the plug-in interface 31, thereby reducing the degree of wear. The entire installation process becomes smoother, faster and simpler. The user can easily complete the installation of the pushing member 3 without having to exert effort or worry about damaging components, which helps to extend the service life of these components and improve the overall reliability of the lock.

[0039] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, specifically, in this embodiment, two second side walls 112 are provided in the mounting cavity 11, and the two second side walls 112 are respectively connected to the two sides of the first side wall 111. Preferably, sliding blocks 32 are respectively provided on both sides of the pusher 3, and the two sliding blocks 32 are respectively slidably connected to the two second side walls 112 to provide guidance for the pusher 3 in the first direction. In this way, on the one hand, through the sliding connection between the sliding blocks 32 and the second side walls 112, precise guidance is provided for the movement of the pusher 3 in the first direction (i.e., the sliding direction). This guiding mechanism ensures that the pusher 3 can maintain a stable trajectory during the sliding process, reducing unnecessary friction and wear caused by offset or shaking. On the other hand, the two second side walls 112 serve as the boundaries of the sliding track of the pusher 3, not only limiting the movement of the pusher 3 in the direction perpendicular to the sliding direction, but also enhancing its stability in the sliding direction. Even when subjected to external force, the pusher 3 can maintain its original position and posture, ensuring the accurate execution of the anti-locking function.

[0040] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, preferably, in this embodiment, a limit block 14 protrudes from the second side wall 112. The limit block 14 is disposed against the side of the pusher 3 away from the first side wall 111 to limit movement of the pusher 3 in the second direction. Thus, the limit block 14 acts as a physical barrier, effectively preventing movement of the pusher 3 in the second direction. This limiting effect, combined with the clamping action of the engaging block 12 and the first side wall 111 on the pusher 3, complements each other, forming a stable support system. Even when subjected to external forces, the pusher 3 can maintain its original position and posture, ensuring the accurate execution of the anti-locking function.

[0041] like Figure 1 and Figure 4 As shown, preferably, in this embodiment, the handle assembly further includes a cover plate 7, which is disposed on the mounting cavity 11 to provide surrounding protection.

[0042] like Figure 4 As shown, specifically, in this embodiment, the handle assembly also includes an elastic member 8. When the push member 3 moves to the anti-locking position, the anti-locking member 2 moves to the first position under the drive of the push member 3; when the push member 3 moves to the anti-locking release position, the elastic member 8 is configured to reset the anti-locking member 2 from the first position to the second position.

[0043] like Figures 1 to 4As shown, specifically, in this embodiment, the lock also includes a handle base 4, which is used to be fixed on doors and windows, and the gripping member 1 can rotate relative to the handle base 4; when the anti-locking member 2 moves to the first position, the anti-locking member 2 is inserted into the handle base 4 to fix the relative position of the gripping member 1 and the handle base 4, and when the anti-locking member 2 moves to the second position, the anti-locking member 2 moves out of the handle base 4 to allow the gripping member 1 to rotate relative to the handle base 4.

[0044] In summary, the handle assembly and the lock including the same disclosed in the present invention can at least bring the following beneficial technical effects:

[0045] 1) The clamping block 12 not only limits the movement of the pusher 3 in the second direction (perpendicular to the sliding direction), but also improves the stability and reliability of the pusher 3 during the sliding process;

[0046] 2) The engaging block 12 is an integral protrusion on the side wall of the mounting cavity 11. It can be engaged with the pusher 3 without any additional processing or installation steps. It also eliminates the need for additional components such as a pressure plate installed in the mounting cavity 11 to limit the movement of the pusher 3. This reduces unnecessary parts and simplifies the structure, thereby lowering production costs and assembly difficulty.

[0047] 3) The sliding fit between the insertion port 31 and the clamping block 12 provides a precise guide for the installation of the pusher 3. During the assembly process, the user only needs to align the insertion port 31 on the pusher 3 with the clamping block 12 and gently push it in to achieve quick and accurate installation of the pusher 3. This design simplifies the installation steps, reduces the installation difficulty, and improves assembly efficiency.

[0048] 4) The design of the first guiding slope 1221 and the second guiding slope 311 helps guide the pusher 3 to slide smoothly into the engaging position, reduces the resistance and noise caused by direct collision, and simplifies the installation process.

[0049] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
