[0030] The present utility model will be further described in detail below in conjunction with the accompanying drawings.
[0031] Embodiment 1
[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, this embodiment discloses a lock body structure, which includes a lock core 1, a handle seat 2 and a fixing structure 3; the lock core 1 includes a lock core shell 11, a lock tongue 12 and a lock core shaft 13, the lock core shaft 13 is rotatably arranged on the lock core shell 11, the lock tongue 12 and the lock core shaft 13 are transmission connected, and under the drive of the lock core shaft 13, the lock tongue 12 can be extended and retracted relative to the lock core shell 11; the handle seat 2 is used to connect the handle 5, and the handle seat 2 is covered on the lock core shell 11, and the handle seat 2 is provided with a first fixing hole 21; the fixing structure 3 includes a connecting block 31 and a first fastener 32, the connecting block 31 is provided on the lock core shell 11, and the connecting block 31 is provided with a second fixing hole 311, the first fastener 32 is connected to the first fixing hole 21 and the second fixing hole 311 along a first direction to fix the relative position of the lock core shell 11 and the handle seat 2, and the first direction is perpendicular to the axial direction of the lock core shaft 13.
[0033] Specifically, in this embodiment, the first direction can refer to Figure 6 The e1 direction in the figure, the axis direction of the lock core shaft 13 can be referred to Figure 6 The e2 direction in .
[0034] The lock body structure provided in this embodiment is that the lock core shaft 13 is used to be connected to the lock rod 7, and the lock rod 7 can drive the lock core shaft 13 to rotate synchronously. The lock rod 7 inserted in the lock core shaft 13 will also be inserted into the handle base 2, so that the handle base 2 and the lock core shell 11 can be fixed in the axial direction of the lock core shaft 13. More importantly, the first fixing hole 21 and the second fixing hole 311 are connected by the first fastener 32, so that the handle base 2 and the lock core shell 11 can be fixed in the first direction. In this way, the relative positions of the handle base 2 and the lock core shell 11 can be fixed in two directions perpendicular to each other, effectively avoiding the problem of the handle base 2 being displaced relative to the lock core shell 11 due to long-term use or improper operation, thereby ensuring that the relative position between the handle base 2 and the lock core shell 11 is always maintained in a preset optimal state, so that the handle 5 can remain smooth when rotating, and there will be no jamming or increased resistance due to position offset, thereby extending the service life of the lock body structure and improving the overall stability and durability of the lock.
[0035] In addition, the handle base 2 is the appearance part of the lock, and its position accuracy and stability are also directly related to the overall aesthetics of the lock. By maintaining the relative position of the handle base 2 and the lock cylinder shell 11 through the fixed structure 3, the neatness and consistency of the lock appearance can be ensured, thereby improving the overall visual effect.
[0036] like Figure 2 and Figure 3As shown, specifically, in this embodiment, the lock core housing 11 has a lock tongue end 113 for the lock tongue 12 to protrude. Preferably, the first fixing hole 21 is provided at one end of the handle base 2 away from the lock tongue end 113, and the connecting block 31 is correspondingly provided at one end of the lock core housing 11 away from the lock tongue end 113. With such a setting, on the one hand, this layout helps to optimize the force-bearing situation of the lock body structure. Since the main force generated during the operation of the handle 5 is a rotational force, and this layout makes the fixing position of the first fastener 32 outside the moment center of the rotational force, thus reducing the shear force and torsional force borne by the first fastener 32, which is beneficial to maintaining its stability and extending its service life. On the other hand, the lock tongue 12 moves within the lock core housing 11 and protrudes through the lock tongue end 113 for locking or unlocking operations. Setting the fixing structure 3 at a position away from the lock tongue end 113 can prevent the first fastener 32 or the connecting block 31 from interfering with the movement trajectory of the lock tongue 12, reducing wear and noise caused by friction, and helping to maintain the smooth operation of the lock and extend its service life. On the further hand, since both the first fastener 32 and the connecting block 31 are away from the lock tongue end 113, installers can more easily access and operate the first fastener 32 without worrying about conflicts with the lock tongue 12 or other internal components, which is more convenient and faster during installation and maintenance.
[0037] Specifically, in this embodiment, the first direction is parallel to the telescopic direction of the lock tongue 12. Of course, in some other embodiments, the first direction can also be perpendicular to the telescopic direction of the lock tongue 12, which can be selected according to actual needs.
[0038] As Figure 1 、 Figure 2 and Figure 3 shown, it can be understood that when this lock body structure is applied to a door system, the lock core housing 11 needs to be fixed to the door leaf frame 61 of the door leaf 6. More preferably, in this embodiment, a fixing block 23 is further provided at one end of the handle base 2 close to the lock tongue end 113, and the fixing block 23 is used to connect with the door leaf frame 61. In this way, both ends of the handle base 2 can be effectively fixed, thereby further improving the installation stability of the handle base 2. Specifically, the fixing block 23 is provided with a third fixing hole 231 for connection.
[0039] As Figure 3 and Figure 6As shown, preferably, in this embodiment, the handle seat 2 is provided with a fourth fixing hole 24, the lock core housing 11 is provided with an oblong hole 115 extending along the telescopic direction of the lock tongue 12, and the fixing structure 3 further includes a third fastener 35. The third fastener 35 is inserted into the fourth fixing hole 24 and the oblong hole 115 along the axis direction of the lock core shaft 13. In this way, on the one hand, the design of the oblong hole 115 enables the lock core housing 11 to adjust its position relative to the door leaf frame 61 in the telescopic direction of the lock tongue 12, so that the lock core housing 11 can adapt to a certain assembly error, and the installation versatility of the lock core housing 11 is improved; on the other hand, the handle seat 2 and the lock core housing 11 can be further fixed in the axis direction of the lock core shaft 13, so that the connection between the handle seat 2 and the lock core housing 11 is more firm and reliable.
[0040] As Figure 3 and Figure 6 shown, specifically, in this embodiment, there are two handle seats 2, and the two handle seats 2 are respectively located on both sides of the lock core housing 11. The third fastener 35 includes a connecting bolt and a connecting nut. The connecting bolt is inserted into the fourth fixing hole 24 of one handle seat 2 and the oblong hole 115 of the lock core housing 11, and the connecting nut is arranged in the fourth fixing hole 24 of the other handle seat 2, and the connecting bolt and the connecting nut are fixed to fix the lock core housing 11 and the two handle seats 2 in the axis direction of the lock core shaft 13.
[0041] As Figure 1 , Figure 3 and Figure 4 shown, more preferably, in this embodiment, a limiting flange 114 protrudes from the outer side wall of the lock tongue end 113, and the limiting flange 114 is used to abut against the side of the door leaf frame 61 away from the handle seat 2. In this way, when installing the lock core housing 11, the limiting flange 114 will naturally abut against the side of the door leaf frame 61 away from the handle seat 2, forming a firm limiting structure. This limiting structure can not only effectively prevent the lock core housing 11 from loosening or falling off due to external force during use, but also ensure the stability of the relative position between the lock core housing 11 and the handle seat 2, improving the sealing performance and safety of the entire lock body structure; on the other hand, the limiting flange 114 also plays a positioning role. When installing the lock core housing 11, the installer can judge whether the lock core housing 11 is correctly installed in place by observing the relative position between the limiting flange 114 and the door leaf frame 61. Once the limiting flange 114 completely abuts against the side of the door leaf frame 61 away from the handle seat 2, it means that the lock core housing 11 has been correctly installed and no additional adjustment or calibration is required.
[0042] As Figure 2 and Figure 3As shown, preferably, in this embodiment, the fixing structure 3 further includes a decorative cover 33 which is embedded in the first fixing hole 21 to block the first fastener 32. In this way, the decorative cover 33 is embedded in the first fixing hole 21, effectively blocking the exposed part of the first fastener 32. On the one hand, it can make the appearance of the lock body structure more neat and unified, achieving a better visual effect; on the other hand, the decorative cover 33 can also protect the first fastener 32 from the influence of the external environment, such as moisture, corrosion or physical collision, etc., which helps to extend the service life of the first fastener 32, thus ensuring the stability and reliability of the lock body structure.
[0043] As Figure 2 and Figure 3 As shown, further, in this embodiment, the lock body structure further includes an inner shell 4 which is fixed inside the handle seat 2. The inner shell 4 is provided with clamping ribs 41, and the side wall of the lock core shell 11 is clamped to the clamping ribs 41 to realize the pre-positioning of the lock core shell 11 and the handle seat 2. In this way, the inner shell 4 is fixed inside the handle seat 2, which can provide a firm support for the entire lock body structure. The close fit and stable connection among the inner shell 4, the handle seat 2 and the lock core shell 11 improve the overall stability of the lock body structure;
[0044] Moreover, the clamping ribs 41 provided on the inner shell 4 cooperate with the side wall of the lock core shell 11 to realize the pre-positioning between the lock core shell 11 and the handle seat 2. On the one hand, the cooperation between the clamping ribs 41 and the side wall of the lock core shell 11 can ensure the accurate alignment between the two, avoiding problems such as deviation or misalignment during the installation process; on the other hand, through the close fit between the clamping ribs 41 and the side wall of the lock core shell 11, a stable connection between the lock core shell 11 and the handle seat 2 is achieved. This connection method not only enhances the structural strength of the lock body, but also reduces the risk of loosening caused by vibration or external force; on the other hand, the pre-positioning function of the clamping ribs 41 simplifies the installation process. The installer only needs to align the clamping ribs 41 with the side wall of the lock core shell 11 and gently push them in to achieve preliminary fixation, without using additional tools or performing complex adjustments. The handle seat 2 and the lock core shell 11 can be quickly assembled, providing convenience for subsequent fastening operations.
[0045] As Figure 2 and Figure 3As shown, preferably, in this embodiment, the inner shell 4 is provided with a relief opening 42, and a partial structure of the connecting block 31 provided with the second fixing hole 311 is located within the relief opening 42. In this way, on the one hand, the design of the relief opening 42 provides sufficient accommodation space for the connecting block 31 and the second fixing hole 311 provided thereon, avoiding interference problems between the inner shell 4 and the connecting block 31, and also avoiding an increase in the overall size of the lock body structure due to the fixing structure 3, which is conducive to the miniaturization and compact design of the lock body structure; on the other hand, since a partial structure of the connecting block 31 is located within the relief opening 42, during installation, the second fixing hole 311 of the connecting block 31 can be directly aligned with the first fixing hole 21, and then fixed with the first fastener 32. This not only simplifies the installation steps, improves the installation efficiency, but also reduces errors caused by improper installation.
[0046] As Figure 3 shown, preferably, in this embodiment, the handle seat 2 is provided with a limiting block 22, and the first fixing hole 21 is penetrated through the limiting block 22. When the handle seat 2 and the inner shell 4 are connected, the limiting block 22 is located within the relief opening 42. In this way, the connection stability and connection accuracy can be improved.
[0047] As Figure 4 shown, preferably, in this embodiment, the lock core housing 11 is provided with a first connection hole 111, the connecting block 31 is provided with a second connection hole 312, and the fixing structure 3 further includes a second fastener 34. The second fastener 34 is inserted into the first connection hole 111 and the second connection hole 312 to fix the connecting block 31 to the lock core housing 11. In this way, on the one hand, the design of the first connection hole 111 and the second connection hole 312 provides a more definite positioning reference for the installation process. When installing the connecting block 31, only need to align the second connection hole 312 on the connecting block 31 with the first connection hole 111 on the lock core housing 11, and then insert the second fastener 34 for fastening. This design reduces errors during the installation process and improves the installation accuracy and efficiency; on the other hand, by adding the first connection hole 111 and the second connection hole 312 and using the second fastener 34 to connect them, the connection strength between the connecting block 31 and the lock core housing 11 can be significantly enhanced, making the entire lock body structure more stable, and improving the durability and safety of the lock body structure.
[0048] It should be noted that, in some other embodiments, the connecting block 31 can also but is not limited to be integrally formed with the lock core housing 11, and can be selected according to actual needs, and is not uniquely limited herein.
[0049] It should be noted that the above fasteners can be but are not limited to bolts or screws, etc., and can be selected according to actual needs, and are not uniquely limited herein.
[0050] In addition, as Figure 2 、Figure 3 and Figure 4 As shown in Figure 4 , the embodiment also provides a lock, which includes a handle 5 and also includes the lock body structure as described above. The handle 5 is arranged on the handle seat 2. This lock has all the advantages of the above-mentioned lock body structure and will not be elaborated here.
[0051] In addition, as Figures 1 to 4 shown in Figures 1 to 4 , the present embodiment also provides a door system, which includes a door leaf 6 and also includes the lock as described above. The lock core 1 is arranged on the door leaf 6, and there are two handle seats 2, and the two handle seats 2 are respectively arranged on both sides of the door leaf 6 in the thickness direction.
[0052] Embodiment Two
[0053] As Figure 5 shown in Figure 5 , the main difference between this embodiment and Embodiment One lies in: the specific connection method between the connecting block 31 and the lock core housing 11 is different. Please refer to the figure. In this embodiment, the lock core housing 11 is provided with a card slot 112, and the connecting block 31 is clamped in the card slot 112. The clamping design of the card slot 112 and the connecting block 31 simplifies the installation process. When installing the connecting block 31, just align the connecting block 31 with the card slot 112 and gently push it in to complete the fixation. Compared with the traditional fastening methods (such as using screws or bolts), the number of parts is reduced, and no additional tools or complex operation steps are required, greatly improving the installation efficiency.
[0054] In summary, the lock body structure disclosed by the present utility model and the lock including it can at least bring the following beneficial technical effects:
[0055] 1) The relative positions of the handle seat 2 and the lock core housing 11 can be fixed in two mutually perpendicular directions, effectively avoiding the problem that the handle seat 2 is displaced relative to the lock core housing 11 due to long-term use or improper operation, and further enabling the handle 5 to rotate smoothly;
[0056] 2) The first fastener 32 and the connecting block 31 are arranged at positions far from the lock tongue end 113, which can avoid interference between the first fastener 32 or the connecting block 31 and the movement track of the lock tongue 12, reduce the wear and noise generated by friction, and contribute to maintaining the smooth operation of the lock and extending its service life;
[0057] 3) A fixing block 23 is also arranged at one end of the handle seat 2 close to the lock tongue end 113, and both ends of the handle seat 2 can be effectively fixed, thereby further improving the installation stability of the handle seat 2;
[0058] 4) The third fastener 35 is inserted along the axial direction of the lock core shaft 13 into the fourth fixing hole 24 and the waist-shaped hole 115. The design of the waist-shaped hole 115 enables the lock core housing 11 to adjust its position relative to the door leaf frame 61 in the telescopic direction of the lock tongue 12, and further fixes the handle base 2 and the lock core housing 11 in the axial direction of the lock core shaft 13;
[0059] 5) The decorative cover 33 is embedded in the first fixing hole 21, effectively shielding the exposed part of the first fastener 32, which can make the appearance of the lock body structure more tidy and unified. The decorative cover 33 can also protect the first fastener 32 from the influence of the external environment to play a protective role.
