Description

Technical Field

[0001] This utility model belongs to the technical field of door and window hardware accessories, specifically relating to lock body structure and locks including the same. Background Technology

[0002] A door system typically includes a door leaf and a lock. The lock is fixed to the door leaf and can switch between an unlocked and locked state to achieve the functions of opening and locking the door. In existing technology, the lock generally consists of a handle, a handle base, and a lock cylinder. The lock cylinder is fixed to the door leaf, and two handle bases are respectively located on both sides of the door leaf in the thickness direction to cover and conceal the lock cylinder. The handle is connected to the handle base.

[0003] However, since the handle needs to rotate during use, under prolonged use or improper operation, the handle seat will be subjected to the force of the handle, which may cause it to deviate relative to the lock cylinder. In other words, there will be a certain deviation between the actual relative position of the handle seat and the lock cylinder and the preset relative position, which will cause the handle to move less smoothly when rotating. Utility Model Content

[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides a lock body structure and a lock including the same, to solve the problem in the prior art that the fixing holes cannot be accurately aligned due to different door leaf thicknesses, which in turn affects the relative position fixation of the lock cylinder shell and the handle seat, ensuring that the handle can remain smooth when rotating, extending the service life of the lock body structure, and improving the overall stability and durability of the lock.

[0005] The technical solution adopted by this utility model to solve its problem is: A lock body structure includes: a lock cylinder, comprising a lock cylinder shell, a lock tongue, and a lock cylinder shaft, the lock cylinder shaft being rotatably mounted on the lock cylinder shell, the lock tongue being drively connected to the lock cylinder shaft, and the lock tongue being extendable and retractable relative to the lock cylinder shell under the drive of the lock cylinder shaft; a first handle seat for connecting a first handle, the first handle seat covering the lock cylinder shell, the first handle seat having a first fixing hole; a connecting block disposed on the lock cylinder shell; a first sliding member slidably mounted on the connecting block along a first direction, the first sliding member having a third fixing hole, the first direction being the axial direction of the lock cylinder shaft; and a first fastener passing through the first fixing hole, the connecting block, and the third fixing hole along a second direction to fix the relative position of the first handle seat and the lock cylinder shell, the second direction being perpendicular to the first direction.

[0006] As an optional implementation, the lock cylinder housing has a latch end for the latch to extend out, the first fixing hole is disposed at the end of the first handle seat away from the latch end, and the connecting block is disposed at the end of the lock cylinder housing away from the latch end.

[0007] As an optional implementation, the connecting block is provided with a first clearance groove extending along a first direction, the first clearance groove and the third fixing hole are disposed opposite to each other, and the first fastener passes through the first fixing hole, the first clearance groove and the third fixing hole along a second direction to fix the relative position of the first handle seat and the lock cylinder shell.

[0008] As an optional implementation, the first fastener includes a first threaded segment and a first head. The first head is connected to one end of the first threaded segment and is located in the first fixing hole. The first threaded segment passes through the connecting block and is threadedly connected to the third fixing hole. Rotating the first threaded segment can move the first sliding member to a position that is fixed against the connecting block.

[0009] As an optional implementation, the first slider is provided with two guide blocks, and a sliding space is formed between the two guide blocks. The sliding space and the connecting block are slidably connected.

[0010] As an optional implementation, the lock body structure further includes a second handle seat and a second fastener. The second handle seat is used to connect the second handle. The second handle seat is provided with a second fixing hole. The connecting block is provided with a fourth fixing hole. The second fastener passes through the second fixing hole and the fourth fixing hole along a second direction to fix the relative position of the second handle seat and the lock cylinder shell.

[0011] As an optional implementation, the lock body structure further includes a second sliding member, a second handle seat, and a second fastener. The second handle seat is used to connect a second handle and is provided with a second fixing hole. The second sliding member slides along a first direction on the connecting block and is provided with a fifth fixing hole. The second fastener passes through the second fixing hole, the connecting block, and the fifth fixing hole along a second direction to fix the relative positions of the second handle seat and the lock cylinder shell.

[0012] As an optional implementation, the connecting block is provided with a second clearance groove extending along a first direction, the second clearance groove and the fifth fixing hole are disposed opposite to each other, and the second fastener passes through the second fixing hole, the second clearance groove and the fifth fixing hole along a second direction to fix the relative position of the first handle seat and the lock cylinder shell.

[0013] As an optional implementation, the lock cylinder shell is provided with a slot, and the connecting block is engaged in the slot.

[0014] In addition, this utility model also discloses a lock, including the lock body structure as described in any of the above embodiments, and further including a first handle, the first handle being disposed on the first handle seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When applied to different door systems, this lock body structure allows adjustment of the position of the first sliding member relative to the connecting block according to the varying thickness of the door leaf. This adjustment ensures that the first fixing hole is always precisely aligned with the third fixing hole, thereby allowing the first fastener to always pass through the first fixing hole, the connecting block, and the third fixing hole in the second direction to fix the relative position of the first handle seat and the lock cylinder housing. Furthermore, the lock cylinder shaft is used to connect to the lock rod, which drives the lock cylinder shaft to rotate synchronously. The lock rod, inserted into the lock cylinder shaft, also inserts into the first handle seat, thus fixing the relative position of the first handle seat and the lock cylinder housing in the first direction. In this way, the lock body structure can fix the relative positions of the first handle seat and the lock cylinder shell in two mutually perpendicular directions, effectively avoiding the problem of the first handle seat being misaligned relative to the lock cylinder shell due to long-term use or improper operation. This ensures that the relative position between the first handle seat and the lock cylinder shell is always kept in the preset optimal state, so that the handle can rotate smoothly without jamming or increased resistance caused by positional deviation, thus extending the service life of the lock body structure and improving the overall stability and durability of the lock.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It is known that existing door systems typically include a door leaf and a lock. The lock is fixed to the door leaf and can switch between unlocked and locked states to achieve the functions of opening and locking the door. In existing technology, the lock generally consists of a handle, a handle base, and a lock cylinder. The lock cylinder is fixed to the door leaf, and two handle bases are respectively located on both sides of the door leaf in the thickness direction to cover and conceal the lock cylinder. The handle is connected to the handle base. However, the handle needs to rotate during use. Under prolonged use or improper operation, the handle base will be subjected to the force of the handle, which may cause it to deviate relative to the lock cylinder. That is to say, there will be a certain deviation between the actual relative position of the handle base and the lock cylinder and the preset relative position, which will cause the handle to move less smoothly when rotating.

[0025] To address the aforementioned issues, the applicant has submitted an earlier application with application number 2024224072674, which provides a lock body structure and a lock including the same. The lock body structure of the earlier application includes a lock cylinder, a handle base, and a fixing structure. The lock cylinder includes a lock cylinder housing, a bolt, and a lock cylinder shaft. The lock cylinder shaft is rotatably mounted on the lock cylinder housing, and the bolt is drively connected to the lock cylinder shaft. Under the drive of the lock cylinder shaft, the bolt can extend and retract relative to the lock cylinder housing. The handle base is used to connect a handle and is fitted onto the lock cylinder housing. The handle base has a first fixing hole. The fixing structure includes a connecting block and a first fastener. The connecting block is mounted on the lock cylinder housing and has a second fixing hole. The first fastener is connected to the first and second fixing holes in a direction perpendicular to the axis of the lock cylinder shaft to fix the relative position of the lock cylinder housing and the handle base. This structure, to a certain extent, avoids the problem of the handle base being misaligned relative to the lock cylinder housing.

[0026] However, the lock body structure in the prior application still has significant drawbacks: the thickness of the door leaf varies in different door systems. Furthermore, the position of the first fixing hole on the connecting block relative to the lock cylinder housing cannot be adjusted. When the door leaf thickness is too large or too small, the first and second fixing holes cannot be precisely aligned. This makes it difficult for the first fastener to connect to the first and second fixing holes along a direction perpendicular to the lock cylinder axis, ultimately resulting in the inability to effectively fix the relative position between the lock cylinder housing and the handle seat. To eliminate the defects in this prior application, the applicant has made iterative improvements based on the prior application and further proposed this application.

[0027] The technical solutions of the embodiments of this application will be further described below with reference to the examples and accompanying drawings.

[0028] Example 1 Please see Figures 1 to 4 This application provides a lock body structure, which includes a lock cylinder 1, a first handle seat 2, a connecting block 3, a first sliding member 4, and a first fastener 5. The lock cylinder 1 includes a lock cylinder shell 11, a bolt (not shown), and a lock cylinder shaft 12. The lock cylinder shaft 12 is rotatably mounted on the lock cylinder shell 11, and the bolt and the lock cylinder shaft 12 are connected by a transmission. Under the drive of the lock cylinder shaft 12, the bolt can extend and retract relative to the lock cylinder shell 11. The first handle seat 2 is used to connect a first handle 10. The first handle seat 2 covers the lock cylinder shell 11 and is provided with a first fixing hole 21. The connecting block 3 is disposed on the lock cylinder shell 11. The first sliding member 4 slides on the connecting block 3 along a first direction and is provided with a third fixing hole 41. The first direction is the axial direction of the lock cylinder shaft 12. The first fastener 5 passes through the first fixing hole 21, the connecting block 3, and the third fixing hole 41 along a second direction to fix the relative position of the first handle seat 2 and the lock cylinder shell 11. The second direction is perpendicular to the first direction.

[0029] The lock body structure disclosed in this application, when applied to different door systems, allows the position of the first sliding member 4 relative to the connecting block 3 to be adjusted according to the different thicknesses of the door leaf. This ensures that the first fixing hole 21 is always precisely aligned with the third fixing hole 41, allowing the first fastener 5 to always pass through the first fixing hole 21, the connecting block 3, and the third fixing hole 41 along the second direction to fix the relative positions of the first handle seat 2 and the lock cylinder shell 11. In addition, the lock cylinder shaft 12 is used to connect with the lock rod, which can drive the lock cylinder shaft 12 to rotate synchronously. The lock rod inserted into the lock cylinder shaft 12 will also be inserted into the first handle seat 2, thereby ensuring that the lock body structure can be adjusted in the first direction. The relative positions of the first handle seat 2 and the lock cylinder shell 11 are fixed upwards. In this way, the lock body structure can fix the relative positions of the first handle seat 2 and the lock cylinder shell 11 in two mutually perpendicular directions. This effectively avoids the problem of the first handle seat 2 being misaligned relative to the lock cylinder shell 11 due to long-term use or improper operation. This ensures that the relative position between the first handle seat 2 and the lock cylinder shell 11 is always kept in the preset optimal state, so that the handle can be rotated smoothly without jamming or increased resistance caused by positional deviation. This extends the service life of the lock body structure and improves the overall stability and durability of the lock.

[0030] like Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the lock cylinder housing 11 has a latch end 111 for the latch to extend out, a first fixing hole 21 is disposed at the end of the first handle seat 2 away from the latch end 111, and a connecting block 3 is disposed at the end of the lock cylinder housing 11 away from the latch end 111. With this arrangement, firstly, by placing the first fixing hole 21 at the end of the first handle seat 2 away from the latch end 111 and the connecting block 3 at the end of the lock cylinder housing 11 away from the latch end 111, more space can be reserved in the direction of the latch end 111 in the lock body structure. This layout avoids placing too many components near the latch end 111, reduces mutual interference between components, and makes the overall lock body structure more compact. Secondly, when installing and adjusting the lock body structure, the first fixing hole 21 and the connecting block 3 are positioned at the end furthest from the bolt end 111, providing operators with more operating space. Operators can more easily adjust the position of the first sliding member 4 relative to the connecting block 3, ensuring precise alignment of the first fixing hole 21 and the third fixing hole 41, and then easily install the first fastener 5. This design simplifies the installation and adjustment process, reduces installation time and labor costs, and improves production efficiency. Furthermore, it facilitates disassembly and reinstallation during subsequent maintenance and component replacement. Thirdly, this layout helps optimize the stress distribution on the lock body structure. Since the handle primarily generates rotational force during operation, this layout places the fixing position of the first fastener 5 outside the torque center of the rotational force, thereby reducing the shear and torsional forces borne by the first fastener 5, which helps maintain its stability and extend its service life.

[0031] like Figure 2 and Figure 3As shown, in one embodiment, the first fastener 5 includes a first threaded section 52 and a first head 51. The first head 51 is connected to one end of the first threaded section 52 and is located inside the first fixing hole 21. The first threaded section 52 passes through the connecting block 3 and is threadedly connected to the third fixing hole 41. Rotating the first threaded section 52 can move the first sliding member 4 to a position where it is secured against the connecting block 3. With this configuration, firstly, when the first sliding member 4 moves to a position where it is secured against the connecting block 3, the first fastener 5 tightly connects the first handle seat 2, the connecting block 3, and the first sliding member 4 together, forming a stable integral structure. This stable fixing method effectively prevents the first handle seat 2 from shifting relative to the lock cylinder shell 11 during long-term use or when subjected to external forces, ensuring the stability and reliability of the lock body structure. Secondly, operators can easily fix the position of the first sliding member 4 relative to the connecting block 3 by simply rotating the first threaded section 52. This operation method does not require complex tools or professional skills, greatly reducing the difficulty of installation and maintenance and improving work efficiency. Whether in the initial installation of the lock or in subsequent maintenance and replacement of parts, the fixing operation can be completed quickly and conveniently. Thirdly, the threaded connection has self-locking properties. Once the first fastener 5 secures the first sliding member 4 against the connecting block 3, it can automatically maintain the fixed state without the need for additional fixing measures. This efficient fixing method reduces installation time and labor costs, while also improving the production efficiency of the lock.

[0032] like Figure 2 and Figure 4 As shown, in one embodiment, the connecting block 3 is provided with a first clearance groove 31 extending along a first direction. The first clearance groove 31 and the third fixing hole 41 are arranged opposite to each other. The first fastener 5 passes through the first fixing hole 21, the first clearance groove 31 and the third fixing hole 41 along a second direction to fix the relative positions of the first handle seat 2 and the lock cylinder shell 11. Thus, regardless of how the first sliding member 4 slides relative to the connecting block 3, the third fixing hole 41 can always connect with the first clearance groove 31. The existence of the first clearance groove 31 facilitates the installation of the first fastener 5. During installation, the operator does not need to worry about the position of the first sliding member 4 affecting the alignment of the first fastener 5 with the third fixing hole 41. The first fastener 5 can be fixed by passing it through the first fixing hole 21, the first clearance groove 31 and the third fixing hole 41 in sequence along the second direction. This simplified installation operation reduces the installation difficulty, improves the installation efficiency, and reduces the installation time and labor costs. Furthermore, it allows for more rational use of the space in the first direction of the connecting block 3, achieving effective installation of the first fastener 5 within a limited space. The compact structural layout makes the internal components of the lock body structure more compact, reducing the gaps and wobbling space between components, and improving the overall stability and reliability of the lock body structure.

[0033] It should be noted that in some other embodiments, the connecting block 3 may also be provided with a plurality of first clearance holes (not shown in the figure) arranged along the first direction. When the first sliding member 4 slides relative to the connecting block 3, the third fixing hole 41 can be arranged opposite to the corresponding first clearance hole. The first fastener 5 passes through the first fixing hole 21, the first clearance hole and the third fixing hole 41 along the second direction to fix the relative position of the first handle seat 2 and the lock cylinder shell 11.

[0034] like Figure 3 and Figure 4 As shown, in one embodiment, the first sliding member 4 is provided with two guide blocks 42, and a sliding space 43 is formed between the two guide blocks 42. The sliding space 43 and the connecting block 3 are slidably connected to provide guidance for the sliding of the first sliding member 4 relative to the connecting block 3. This precise guidance avoids the first sliding member 4 from deviating, shaking or tilting during the sliding process, ensuring the straightness and stability of the sliding, so that the first sliding member 4 can accurately reach the expected position, meeting the requirements of precise cooperation of various components inside the lock. Furthermore, the connecting block 3 is fixed relative to the lock cylinder shell 11. The sliding connection between the sliding space 43 and the connecting block 3 forms a reliable connection relationship between the first sliding member 4 and the connecting block 3, providing stable support for the first sliding member 4. During the sliding process of the first sliding member 4, it can withstand a certain amount of external force, preventing the first sliding member 4 from deviating from the normal sliding trajectory or being damaged due to force, thereby improving the overall stability of the lock body structure.

[0035] like Figure 1 and Figure 2As shown, in one embodiment, the lock body structure further includes a second handle seat 6 and a second fastener 7. The second handle seat 6 is used to connect the second handle 20. The second handle seat 6 is provided with a second fixing hole 61, and the connecting block 3 is provided with a fourth fixing hole 32. The second fastener 7 passes through the second fixing hole 61 and the fourth fixing hole 32 along the second direction to fix the relative position of the second handle seat 6 and the lock cylinder shell 11. Thus, the second fastener 7 passes through the second fixing hole 61 and the fourth fixing hole 32 along the second direction, tightly connecting the second handle seat 6 to the connecting block 3. This effectively withstands the rotational force, torque, and other external forces generated by the second handle 20 during operation, preventing the second handle seat 6 from loosening, shifting, or shaking relative to the lock cylinder shell 11. This ensures the stability of the handle during long-term use, reduces malfunctions caused by loose components, such as uneven handle rotation or jamming, and improves the overall reliability of the lock. Furthermore, during installation, simply place the second handle seat 6 in the appropriate position, align the second fixing hole 61 with the fourth fixing hole 32, insert the second fastener 7, and tighten it to complete the fixation. This installation method does not require complex tools or operating steps, reducing the installation difficulty. Importantly, since the position of the first sliding member 4 relative to the connecting block 3 is adjustable, the distance between the third fixing hole 41 and the second fixing hole 61 in the first direction is also adjustable. This allows the first handle seat 2 and the second handle seat 6 to adapt to different door thicknesses when installed on opposite sides of the door leaf.

[0036] like Figure 2 and Figure 4 As shown, in one embodiment, the lock cylinder housing 11 is provided with a slot 114, and the connecting block 3 is snapped into the slot 114. This snap-fit ​​design between the slot 114 and the connecting block 3 simplifies the installation process. When installing the connecting block 3, simply align the connecting block 3 with the slot 114 and gently push it in to complete the fixation. This reduces the number of parts and eliminates the need for additional tools or complex operating steps, greatly improving installation efficiency.

[0037] It should be noted that in some other embodiments, the connecting block 3 can also be fixed to the lock cylinder shell 11 by means of pin or screw connection.

[0038] It should be noted that in some other embodiments, the connecting block 3 is integrally formed into the lock cylinder shell 11.

[0039] like Figure 2 , Figure 3 and Figure 4As shown, more preferably, in this embodiment, the outer wall of the latch end 111 protrudes with a limiting flange 112. The limiting flange 112 is used to abut against the side of the door frame away from the handle seat. Thus, when the lock cylinder shell 11 is installed, the limiting flange 112 will naturally abut against the side of the door frame away from the handle seat, forming a solid limiting structure. This limiting structure can not only effectively prevent the lock cylinder shell 11 from loosening or falling off due to external forces during use, but also ensure the stability of the relative position between the lock cylinder shell 11 and the handle seat, improving the sealing and security of the entire lock body structure. On the other hand, the limiting flange 112 also plays a positioning role. When installing the lock cylinder shell 11, the installer can judge whether the lock cylinder shell 11 has been correctly installed by observing the relative position of the limiting flange 112 and the door frame. Once the limiting flange 112 is completely abutted against the side of the door frame away from the handle seat, it means that the lock cylinder shell 11 has been installed correctly and no further adjustment or correction is required.

[0040] like Figure 2 and Figure 3 As shown, preferably, in this embodiment, the first handle seat 2 is provided with a sixth fixing hole 22, the lock cylinder shell 11 is provided with a waist-shaped hole 113 extending along the extension and retraction direction of the lock tongue, and the lock body structure also includes a third fastener 9, which is inserted into the sixth fixing hole 22 and the waist-shaped hole 113 along the first direction. In this way, on the one hand, the design of the waist-shaped hole 113 allows the lock cylinder shell 11 to be adjusted relative to the door leaf frame in the extension and retraction direction of the lock tongue, thereby allowing the lock cylinder shell 11 to adapt to certain assembly errors and improving the installation versatility of the lock cylinder shell 11; on the other hand, the first handle seat 2 and the lock cylinder shell 11 can be further fixed in the first direction, thereby making the connection between the first handle seat 2 and the lock cylinder shell 11 more firm and reliable.

[0041] like Figure 2 As shown, in one embodiment, the second fastener 7 includes a second threaded section 72 and a second head 71. The second head 71 is connected to one end of the second threaded section 72 and is located inside the second fixing hole 61. The second threaded section 72 passes through the connecting block 3 and is threadedly connected to the third fixing hole 41.

[0042] like Figure 1 and Figure 2 As shown in one embodiment, the lock body structure also includes a decorative cover 8, which is embedded in the first fixing hole 21 and the second fixing hole 61 to cover the heads of the first fixing member and the second fixing member.

[0043] like Figure 1 and Figure 2 As shown, this application embodiment also provides a lock, including the lock body structure of any of the above embodiments, and also includes a first handle 10, which is disposed on a first handle seat 2.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, the lock further includes a second handle 20, which is disposed on a second handle seat 6.

[0045] Example 2 The main difference between this embodiment and Embodiment 1 is that the lock body structure also includes a second sliding member (not shown in the figure), a second handle seat 6, and a second fastener 7. The second handle seat 6 is provided with a second fixing hole 61. The second sliding member slides along the first direction on the connecting block 3. The second sliding member is provided with a fifth fixing hole (not shown in the figure). The second fastener 7 passes through the second fixing hole 61, the connecting block 3, and the fifth fixing hole along the second direction to fix the relative position of the second handle seat 6 and the lock cylinder shell 11. In this way, the position of the second sliding member relative to the connecting block 3 can be adjusted according to the different thicknesses of the door leaf, so that the fifth fixing hole is always precisely aligned with the second fixing hole 61. This allows the second fastener 7 to always pass through the second fixing hole 61, the connecting block 3, and the fifth fixing hole along the second direction to fix the relative position of the first handle seat 2 and the lock cylinder shell 11.

[0046] In one embodiment, the second fastener 7 includes a second threaded section 72 and a second head 71. The second head 71 is connected to one end of the second threaded section 72 and is located inside the second fixing hole 61. The second threaded section 72 passes through the connecting block 3 and is threadedly connected to the third fixing hole 41. Rotating the second threaded section 72 can move the second sliding member to a position where it is secured against the connecting block 3. With this configuration, firstly, when the second sliding member moves to a position where it is secured against the connecting block 3, the second fastener 7 tightly connects the second handle seat 6, the connecting block 3, and the second sliding member together, forming a stable integral structure. This stable fixing method effectively prevents the second handle seat 6 from shifting relative to the lock cylinder shell 11 during long-term use or under external force, ensuring the stability and reliability of the lock body structure. Secondly, operators can easily fix the position of the second sliding member relative to the connecting block 3 by simply rotating the second threaded section 72. This operation method does not require complex tools or professional skills, greatly reducing the difficulty of installation and maintenance and improving work efficiency. Whether in the initial installation of the lock or in subsequent maintenance and replacement of parts, the fixing operation can be completed quickly and conveniently. Thirdly, the threaded connection has self-locking properties. Once the second fastener 7 secures the second sliding member against the connecting block 3, it can automatically maintain the fixed state without the need for additional fixing measures. This efficient fixing method reduces installation time and labor costs, while also improving the production efficiency of the lock.

[0047] In one embodiment, the connecting block 3 is provided with a second clearance groove (not shown) extending along a first direction. The second clearance groove and the fifth fixing hole are arranged opposite to each other. The second fastener 7 passes through the second fixing hole 61, the second clearance groove and the fifth fixing hole along a second direction to fix the relative positions of the first handle seat 2 and the lock cylinder shell 11. Thus, regardless of how the second sliding member slides relative to the connecting block 3, the fifth fixing hole can always connect with the second clearance groove. The existence of the second clearance groove facilitates the installation of the second fastener 7. During installation, the operator does not need to worry about the position of the second sliding member affecting the alignment of the second fastener 7 with the fifth fixing hole. The second fastener 7 can be fixed simply by passing it through the second fixing hole 61, the second clearance groove, and the fifth fixing hole in sequence along the second direction. This simplified installation operation reduces the installation difficulty, improves the installation efficiency, and reduces the installation time and labor costs. Furthermore, it allows for more rational use of the space in the first direction of the connecting block 3, enabling the effective installation of the second fastener 7 within a limited space. The compact structural layout makes the components inside the lock body structure more compact, reducing the gaps and wobbling space between components, and improving the overall stability and reliability of the lock body structure.
