Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to an intelligent lock. Background Art

[0002] The inner lock core of the door lock is the core component of the door lock, which is responsible for controlling the opening and closing of the door lock. The inner lock core is usually composed of multiple precision parts.

[0003] In a smart door lock based on the Internet disclosed in the prior art CN217681103U, a battery slot is provided on the side of the rear panel away from the door body, a cover plate is movably connected to the battery slot, a right-angle hook is integrally formed on the cover plate, and a right-angle slot cooperating with the right-angle hook is provided on the rear panel. After the battery is placed in the battery slot, the cover plate is placed at the battery slot and the battery is hidden in the battery slot through the plug-in cooperation of the right-angle hook and the right-angle slot. After the right-angle hook and the right-angle slot are plug-in cooperated, the handle is rotated to rotate the movable rod until the pin rod is aligned with the pin slot, so that the spring is deformed and twisted in the radial direction, and then in the process of sliding the cover plate downward, the pin rod extends from the pin slot to the inside of the battery slot, the handle is released, the spring recovers its deformation, the pin rod is misaligned with the pin slot, and the cover plate is fixed.

[0004] When fixing the cover plate, the above-mentioned smart door lock needs to slide the right-angle hook on the cover plate into the right-angle slot, and rotate the handle until the pin rod is aligned with the pin slot before sliding the cover plate downward to make the right-angle hook and the right-angle slot plug in. The pin rod is plugged into the pin slot until the pin rod passes through the pin slot and then the handle is released. The pin rod deviates from the pin slot under the action of the spring, thereby positioning the cover plate at the battery slot. When the battery needs to be replaced, the pin rod and the right-angle hook need to be operated in reverse. Therefore, it is relatively difficult to fix or remove the cover plate, thereby reducing the efficiency of battery replacement. Utility Model Content

[0005] The purpose to be achieved by the utility model is to provide a smart lock to solve the problem of low efficiency in cover plate disassembly and installation and to improve the efficiency of battery replacement.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A smart lock comprises an inner lock body, wherein a battery compartment for placing batteries is arranged in the inner lock body, the inner lock body comprises an outer shell, the outer shell is provided with a placement opening for replacing batteries and a cover body for closing the placement opening, the cover body comprises a main body, an abutment member and a limit member, the abutment member is slidably arranged on the main body and extends out along a first direction so that the main body abuts against the outer shell, the abutment member has a tendency to keep extending out of the main body along the first direction, the limit member is movably arranged on the main body, the limit member has a locking position and an unlocking position, the limit member blocks the abutment member in the locking position to prevent the abutment member from sliding out of the outer shell in a second direction, and the limit member avoids the abutment member in the unlocking position so that the abutment member can slide in the second direction to separate from the outer shell, the second direction is opposite to the first direction.

[0008] After adopting the above technical solution, the utility model has the following advantages: after the battery is placed in the battery compartment, one end of the main body is abutted against the inner wall of the placement port, at this time, the limiter is in the unlocking position, the abutting member is pressed to make the abutting member slide along the second direction, when the end of the abutting member extending out of the main body abuts against the inner wall of the placement port, the abutting member abuts against the outer shell through the tendency of the abutting member to extend out of the main body in the first direction, and then the limiter is operated on the main body, so that the limiter enters the locking position, thereby blocking the abutting member from moving in the second direction and separating from the outer shell, and the installation of the cover is completed. Conversely, when the cover is to be removed, the limiter is first operated to enter the unlocking position, and then the abutting member is pressed to slide along the second direction until the end of the abutting member extending out of the main body is separated from the outer shell, and the cover can be removed. The installation or removal operation of the cover is relatively simple, and the efficiency of battery replacement is improved. The limiter has a locking position and an unlocking position. After the limiter enters the locking position, it can prevent children or other unexpected situations from causing the cover to be opened, effectively preventing the battery from being accidentally removed from the battery compartment, and ensuring that the smart lock can work normally.

[0009] Furthermore, the limiting member is rotatably connected to the main body, and a clearance groove is provided on the outer peripheral side wall of the limiting member. The clearance groove is offset from the abutment member when the limiting member is in the locked position, and faces the abutment member when the limiting member is in the unlocked position.

[0010] By adopting the above-mentioned technical solution, when the limit member is in the locking position, the abutment member and the giving way groove on the limit member are misaligned. When the abutment member slides along the second direction, the abutment member cannot be separated from the outer shell because it abuts on the outer peripheral side wall of the limit member, thereby reducing the possibility of the abutment member detaching from the outer shell; when the main body needs to be disassembled, the limit member is rotated so that the giving way groove faces the abutment member, and the abutment member can extend into the giving way groove when sliding along the second direction, thereby separating from the outer shell, facilitating the disassembly of the cover body. The limit member is connected to the main body in a rotating manner, and the limit member is not easy to move from the locking position to the unlocking position, which can effectively prevent the limit member from accidentally unlocking the abutment member.

[0011] Furthermore, an inserting groove is provided on the outer peripheral wall of the limiting member, the positioning groove is located in the inserting groove, and the abutment member remains inserted in the inserting groove to prevent the limiting member from being separated from the main body.

[0012] By adopting the above-mentioned technical solution, when the limit member is in the locked position or the unlocked position, the abutment member is inserted into the insertion slot. When the limit member is separated from the main body due to external force or vibration, the abutment member abuts against the side wall of the insertion slot, thereby reducing the possibility of the limit member being separated from the main body, and further reducing the possibility of the battery in the battery compartment being accidentally separated from the battery compartment due to the limit member accidentally separating from the main body.

[0013] Furthermore, an elastic member is provided between the abutment member and the main body, and the elastic force of the elastic member enables the abutment member to maintain a tendency to extend out of the main body along the first direction; or / and, a pressing plate is provided on the side surface of the abutment member facing away from the battery compartment for receiving force to drive the abutment member to move in the second direction.

[0014] By adopting the aforementioned technical solution, the abutment member is pushed on the main body to abut the outer shell through the elastic member, so that the abutment member always maintains the tendency to abut the outer shell, reducing the possibility of the abutment member being separated from the outer shell, and further reducing the possibility of the battery in the battery compartment accidentally being separated from the battery compartment due to the main body being separated from the placement opening; or, through the setting of the pressing piece, it is convenient to drive the abutment member to slide along the second direction, thereby facilitating the disassembly and assembly of the main body from the placement opening, and further facilitating the replacement of the battery in the battery compartment.

[0015] Furthermore, a blocking member is provided on the main body for preventing the abutting member from separating from the main body.

[0016] By adopting the above technical solution, the blocking member blocks the abutment member in the first direction, reducing the possibility of the abutment member detaching from the limiting member when it has a tendency to extend out of the main body, and reducing the effect of the main body covering the placement opening affected by the detachment of the abutment member.

[0017] Furthermore, a blocking groove is provided on one side surface of the main body facing the placement opening, the blocking member is inserted into the blocking groove and blocks the abutting member from separating from the main body along the first direction, and the blocking member abuts against the groove wall of the blocking groove along the first direction.

[0018] By adopting the above-mentioned technical solution, the blocking member is inserted into the blocking groove, one side of the blocking member blocks the abutting member along the first direction, and the other side abuts the groove wall of the blocking groove along the first direction, thereby reducing the possibility of the abutting member separating from the main body. At the same time, the blocking member abuts the groove wall of the blocking groove, thereby reducing the possibility of the blocking member separating from the blocking groove during the process of preventing the abutting member from separating from the main body, thereby further improving the blocking effect of the blocking member in preventing the abutting member from separating from the main body along the first direction.

[0019] Furthermore, the main body is provided with an installation groove for installing an abutment member and a slide groove for installing a limit member. The abutment member slides in the installation groove. The slide groove is located on the outer side of the main body. One end of the slide groove is connected to the installation groove, and the other end of the slide groove is away from the installation groove. The limit member can slide back and forth in the slide groove. The limit member slides to one end of the slide groove and enters the locking position. The limit member slides to the other end of the slide groove and leaves the locking position.

[0020] By adopting the above-mentioned technical solution, the abutment member is slidably installed in the installation groove along the first direction, and one end of the abutment member away from the limiting member extends out of the installation groove and abuts against the outer shell. By sliding the abutment member in the installation groove, the convenience of the abutment member abutting or detaching from the outer shell is improved. The limiting member slides back and forth in the slide groove, which is convenient for switching the locking position and the unlocking position of the limiting member, thereby improving the efficiency of the main body covering the placement opening, facilitating the replacement of the battery in the battery compartment, and at the same time, reducing the possibility of the abutment member detaching from the outer shell, causing the battery in the battery compartment to be exposed.

[0021] Furthermore, an auxiliary groove is provided on the side surface of the limit member facing away from the battery compartment, and a tool is inserted into the auxiliary groove to drive the limit member to switch between the locked position and the unlocked position; or, an auxiliary rib is provided on the side surface of the limit member facing away from the battery compartment, and an external force acts on the auxiliary rib to drive the limit member to switch between the locked position and the unlocked position.

[0022] By adopting the above-mentioned technical solution, when it is necessary to switch the locking position and the unlocking position of the limit member, the disassembly and assembly tool is inserted into the auxiliary groove to drive the limit member to move, thereby facilitating the switching of the locking position and the unlocking position, reducing the difficulty of disassembling the main body on the outer shell, and facilitating the switching of the battery in the battery compartment; the external force for disassembling or installing the main body can also be applied to the auxiliary rib on the side of the limit member facing away from the battery compartment, thereby reducing the use of tools, so that even if the replacement personnel do not have tools in their hands, they can still move the limit member through the auxiliary rib to switch the locking position and the unlocking position of the limit member, thereby reducing the difficulty of disassembling the main body.

[0023] Furthermore, the inner lock body also includes an end cover for fixing on the door, the end cover is connected to the outer shell by a rotating buckle, the inner lock body is provided with a guide column extending out of the inner lock body, and the end cover is provided with a guide hole, and the guide column is inserted into the guide hole before the end cover contacts the outer shell to guide the rotation buckle to align.

[0024] By adopting the above-mentioned technical solution, when installing the smart lock, since the end cover is generally fixed on the door panel before the inner lock body, when the end cover and the outer shell of the inner lock body are fixed, they are rotated and plugged in after being aligned by the rotating buckle. However, due to the small size of the end cover, when the outer shell is close to the end cover, the outer shell blocks the rotating buckle between the end cover and the outer shell, and the rotating buckle is located on the inner wall of the outer shell. When the line of sight is blocked, the installer can insert the guide column on the inner lock body into the guide hole on the end cover. In the process of the inner lock body gradually approaching the end cover, the guide column remains inserted in the guide hole, which facilitates the alignment of the end cover and the rotating buckle on the outer shell, further reducing the difficulty of the installer to install the inner lock body and the end cover.

[0025] Furthermore, the guide post is elastically connected to the inner lock body, the guide hole is an arc-shaped hole, and the guide post slides along the guide hole during the connection process between the outer shell and the end cover.

[0026] By adopting the above-mentioned technical solution, when the inner lock body and the end cover are plugged in, the guide column increases the length of the guide column extending out of the inner lock body under the elastic connection. When the installation space of the inner lock body and the end cover is blocked, the increased length of the guide column facilitates the plugging of the guide column and the guide hole, further reducing the difficulty of installing the inner lock body and the end cover when the space is blocked. At the same time, the elastic connection causes the elastic connection to be compressed after the outer shell and the end cover are installed, reducing the influence of the guide column on the installation of the inner lock body and the end cover in the length direction due to its long length. When the rotating buckle is rotated and clamped, the arc-shaped wall of the guide hole guides the rotation of the inner lock body, thereby facilitating the inner lock body and the end cover to be clamped and positioned in the axial direction of the inner lock body.

[0042] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0043] like Figure 1 and Figure 2 As shown, the utility model provides a smart lock, including an inner lock body 1, a battery compartment for placing batteries is provided on the inner lock body 1, and the inner lock body 1 includes a shell 12, and the shell 12 is provided with a placement port 121 for replacing batteries and a cover 2 for closing the placement port 121. The battery is placed in the battery compartment, and when replacing the battery, a new battery can be placed from the placement port 121 of the shell 12. After the battery is replaced, the placement port 121 on the shell 12 is closed by using the cover 2, so that the battery placed in the battery compartment can be hidden, reducing the possibility of battery exposure and reducing the possibility of the battery being out of the battery compartment due to exposure.

[0044] In the embodiment, in order to facilitate the cover body 2 to close or open the placement opening 121, the cover body 2 includes a main body 21, abutting members 22 and a limiting member 23. To clearly illustrate the installation method of the cover body 2, a first direction 24 and a second direction 25 are preset on the main body 21. The first direction 24 is opposite to the second direction 25. The abutting member 22 is slidably arranged on the main body 21. The abutting member 22 has a tendency to extend out of the main body 21 along the first direction 24 and abut against the housing 12. The limiting member 23 is rotatably arranged on the main body 21. The limiting member 23 has a locking position. And the unlocking position, after the main body 21 closes the placement opening 121, the limiting member 23 is in the locking position to prevent the abutment member 22 from detaching from the shell 12 along the second direction 25. When the main body 21 needs to open the placement opening 121 or close the placement opening 121, the limiting member 23 is in the unlocking position to avoid the sliding of the abutment member 22 along the second direction 25, so that the abutment member 22 abuts against the shell 12 and slides when the main body 21 closes the placement opening 121, or the abutment member 22 detaches from the shell 12 when the main body 21 opens the placement opening 121.

[0045] During the specific operation, one end of the main body 21 is abutted against the inner wall of the placement opening 121, and the limiting member 23 is moved so that the limiting member 23 is in the unlocked position. Then, the other end of the main body 21 is pressed toward the placement opening 121, and the abutting member 22 slides along the second direction 25 until the end of the abutting member 22 extending out of the main body 21 abuts against the shell 12. The abutting member 22 abuts against the shell 12 by the tendency of the main body 21 to extend out of the main body 21, so that the main body 21 is stably covered in the placement opening 121. After the main body 21 closes the placement opening 121, the limiting member 23 is moved again. The part 23 is arranged so that the limit part 23 is in the locked position, reducing the possibility of the abutting part 22 sliding along the second direction 25 and separating from the shell 12. Compared with the prior art, the operation of closing or opening the placement opening 121 of the main body 21 is simpler, thereby improving the efficiency of replacing the battery in the battery compartment. In addition, the limit part 23 has a locked position and an unlocked position. After the limit part 23 enters the locked position, it can prevent children or other unexpected situations from causing the main body 21 to be opened, effectively preventing the battery from being accidentally removed from the battery compartment, and ensuring that the smart lock can work normally.

[0046] In another embodiment, if Figure 3As shown, in order to improve the locking or unlocking effect of the limiting member 23 on the abutment member 22, the limiting member 23 includes a limiting roller 231, which is rotatably installed on the main body 21, and a yielding groove 2311 is provided on the outer peripheral wall of the limiting roller 231. When the main body 21 closes or opens the placement opening 121, the yielding groove 2311 faces the abutment member 22, and the abutment member 22 slides along the second direction 25 and is inserted into the yielding groove 2311, so that the end of the abutment member 22 extending out of the main body 21 is separated from the shell 12; after the main body 21 closes the placement opening 121, the limiting roller 231 is rotated to make the yielding groove 2311 staggered from the abutment member 22, and when the abutment member 22 slides along the second direction 25, it cannot be inserted into the yielding groove 2311, thereby preventing the abutment member 22 from being separated from the shell 12 and opening the placement opening 121.

[0047] In this embodiment, in order to reduce the possibility of the limiting roller 231 being separated from the main body 21, an insertion groove 2312 is provided on the outer peripheral wall of the limiting roller 231, and the positioning groove 2311 is located in the insertion groove 2312. When the limiting roller 231 is in the unlocking position, Figure 4-1 As shown, one end of the abutment member 22 facing the limiting roller 231 is inserted into the clearance groove 2311. When the limiting roller 231 is in the locking position, as shown in FIG. Figure 4-2 As shown, one end of the abutment member 22 facing the limiting roller 231 is offset from the clearance groove 2311 and inserted into the insertion groove 2312. Regardless of whether the limiting roller 231 is in the locked position or the unlocked position, the abutment member 22 always remains inserted into the insertion groove 2312, reducing the possibility of the limiting roller 231 detaching from the main body 21 along the direction of the battery compartment toward the placement port 121.

[0048] like Figure 4-1 and Figure 4-2 As shown, the limiting roller 231 is provided with an abutment rib 2313, and the abutment rib 2312 faces the abutment member 22 when the limiting roller 231 is in the locking position. A limiting notch 225 is provided on the end of the abutment member 22 facing the limiting roller 231. When the limiting roller 231 is in the locking position, the abutment rib 2313 is plugged into the limiting notch 225 to limit the rotation of the limiting roller 231. When the limiting roller 231 is in the unlocking position, the abutment member 22 faces the yield groove 2311 on the limiting roller 231.

[0049] In this embodiment, if Figure 4-1 and Figure 4-2 As shown, the groove wall on the left side of the limiting notch 225 has a smaller inclination angle than the groove wall on the right side of the limiting notch 225 , which facilitates the abutting rib 2313 to enter or move out of the limiting notch 225 .

[0050] In another embodiment, if Figure 5As shown, in order to facilitate the installation of the abutment member 22 and the limiting member 23, an installation groove 211 for installing the abutment member 22 and a sliding groove 212 for installing the limiting member 23 are provided on the main body 21. The installation groove 211 passes through one end surface of the main body 21 along the first direction 24. The abutment member 22 is slidably arranged in the installation groove 211, and one end of the abutment member 22 extends out of the notch of the installation groove 211 to abut against the outer shell 12.

[0051] In this embodiment, if Figure 5 As shown, in order to facilitate the installation of the limit member 23, the limit member 23 includes a limit block 232, the slide groove 212 extends perpendicular to the second direction 25 and is located on the outer side of the main body 21, the limit block 232 is slidably arranged in the slide groove 212, the limit block 232 can reciprocate in the slide groove 212, and an insertion groove 2312 is provided on one side of the limit block 232 facing the abutment member 22, and the end of the abutment member 22 facing the slide groove 212 is always kept plugged with the insertion groove 2312, and the groove wall of the insertion groove 2312 is provided with a yield groove 2311 distributed along the sliding direction of the limit block 232 and an abutment convex rib 2313. When the limit block 232 is in the unlocked position, as shown in FIG. Figure 6-1 As shown, the limit block 232 is on the left side of the slide slot 212. At this time, the right side of the slide slot 212 and the clearance groove 2311 form an escape space for the abutment member 22 to be inserted. The limit block 232 is in the locked position. Figure 6-2 As shown, at this time, the limit block 232 is on the right side of the slide slot 212 , and at this time, the limit block 232 blocks the bottom end of the abutment member 22 , so that the abutment member 22 cannot be unlocked.

[0052] In another embodiment, if Figure 7 and Figure 8 As shown, in order to ensure that the abutment 22 has a tendency to extend out of the main body 21 and abut against the shell 12, an elastic member 26 is provided between the abutment 22 and the main body 21. Specifically, the elastic member 26 includes an abutment spring, one end of which is mounted on the main body 21 and the other end is mounted on the abutment 22. The abutment spring pushes the abutment 22 on the main body 21 so that the abutment 22 has a tendency to extend out of the main body 21 along the first direction 24 and abut against the shell 12.

[0053] In this embodiment, there are two abutment springs distributed along a direction perpendicular to the first direction 24, and both abutment springs push the abutment member 22 along the first direction 24, so that the end of the abutment member 22 away from the limiting member 23 extends out of the main body 21 and abuts against the outer shell 12. By installing two abutment springs, the abutment member 22 has the effect of maintaining the tendency of extending out of the main body 21 along the first direction 24 and abutting against the outer shell 12, thereby improving the abutment force of the abutment member 22.

[0054] In another embodiment, if Figure 7 and Figure 8As shown, in order to facilitate opening the placement opening 121, a pressing piece 224 is provided on the side surface of the abutment 22 facing away from the battery compartment, which is used to receive force to drive the abutment 22 to move along the second direction 25. The pressing piece 224 is arranged away from one end of the abutment 22 and protrudes from the main body 21. When the placement opening 121 needs to be opened, the pressing piece 224 is pushed so that the abutment 22 slides along the second direction 25 to separate from the housing 12. The setting of the pressing piece 224 facilitates driving the abutment 22 to slide along the second direction 25, thereby facilitating the opening of the placement opening 121.

[0055] In another embodiment, if Figure 7 and Figure 8 As shown, in order to prevent the abutment 22 from sliding off the main body 21 along the first direction 24, a blocking member 27 for blocking the abutment 22 from separating from the main body 21 is provided on the main body 21. Specifically, a blocking groove 213 is provided on the side surface of the main body 21 facing the battery compartment, and the blocking member 27 includes a blocking frame, the abutment 22 includes an abutment portion 221, a sliding portion 222 integrally arranged with the abutment portion 221, and a plug-in portion 223 integrally arranged with the sliding portion 222, the sliding portion 222 and the plug-in portion 223 are slidably arranged in the main body 21 and the plug-in portion 223 faces the limiting member 23, one end of the abutment portion 221 is connected to the sliding portion 222, and the other end extends out of the main body 21 and abuts against the shell 12, after the blocking frame extends out of the blocking groove 213 on the side facing away from the battery compartment, the sliding portion 222 is blocked on the side of the sliding portion 222 facing the abutment portion 221, thereby preventing the sliding portion 222 from separating from the main body 21 along the first direction 24.

[0056] In this embodiment, one side of the blocking frame located in the blocking groove 213 abuts against the groove wall of the blocking groove 213 when the sliding portion 222 abuts against the blocking frame, reducing the possibility of the blocking frame detaching from the blocking groove 213, thereby improving the blocking effect of the blocking frame to prevent the sliding portion 222 from detaching from the main body 21.

[0057] In another embodiment, if Figure 7 As shown, in order to improve the stability of the main body 21 in closing the placement opening 121, a block 214 is provided on one end of the main body 21 for abutting against the inner wall of the placement opening 121 on the outer shell 12. Specifically, when the main body 21 closes the placement opening 121, the block 214 extends into the outer shell 12 and abuts against the inner wall of the outer shell 12. By abutting the block 214 against the inner wall of the outer shell 12, the possibility of the main body 21 detaching from the placement opening 121 is reduced.

[0058] In another embodiment, if Figure 3 As shown, an auxiliary groove 233 is provided on the side surface of the limit member 23 facing away from the battery compartment. When it is necessary to switch the locked position and the unlocked position, a common tool such as a flat-head screwdriver can be inserted into the auxiliary groove 233 to assist in switching the locked position and the unlocked position of the limit member 23.

[0059] In order to facilitate the switching of the locking position and the unlocking position of the limit member 23, an auxiliary convex rib can also be provided on the side surface of the limit member 23 facing away from the battery compartment. When it is necessary to switch the locking position and the unlocking position, an external force acts on the auxiliary convex rib to switch the locking position and the unlocking position of the limit member 23, thereby reducing the difficulty of the main body 21 to open or close the placement opening 121.

[0060] In another embodiment, if Fig. 9 As shown, the inner lock body 1 further includes an end cap 14 for fixing on the door, and the end cap 14 is connected to the outer shell 12 by a rotating buckle. When installing the inner lock body 1, it is necessary to align the rotating buckle between the outer shell 12 of the inner lock body 1 and the end cap 14, and then rotate the inner lock body 1 so that the rotating buckle can clamp and position the inner lock body 1 and the end cap 14 along the axial direction of the inner lock body 1.

[0061] In this embodiment, if Fig. 9 and Fig.10 As shown, in order to facilitate the alignment of the rotating buckle, a guide column 13 extending out of the inner lock body 1 is provided on the inner lock body 1, and a guide hole 141 is provided on the end cover 14. When the inner lock body 1 and the end cover 14 are installed, the guide column 13 is inserted into the guide hole 141 to guide the alignment of the rotating buckle.

[0062] In view of the situation that the insertion of the guide column 13 and the guide hole 141 is affected by the small space when the inner lock body 1 and the end cover 14 are installed, the guide column 13 is elastically connected to the inner lock body 1 through an elastic connector 131. The elastic connection of the elastic connector 131 increases the length of the guide column 13 extending out of the inner lock body 1, which is convenient for the insertion of the guide column 13 and the guide hole 141 in a small space and when the line of sight is blocked. After the end of the guide column 13 away from the inner lock body 1 is inserted into the guide hole 141, as the inner lock body 1 approaches the end cover 14, the elastic connector 131 between the guide column 13 and the inner lock body 1 is compressed, thereby reducing the influence of the increased length of the guide column 13 on the installation of the inner lock body 1 and the end cover 14, and at the same time facilitating the alignment of the rotating buckle between the inner lock body 1 and the end cover 14.

[0063] like Fig.10 As shown, in order to facilitate the rotational guidance of the rotating buckle, the guide hole 141 is an arc-shaped hole. After the guide column 13 is inserted into the guide hole 141, the guide column 13 abuts against the inner hole wall of one end of the guide hole 141, thereby improving the efficiency of aligning the rotating buckle. During the rotational connection between the shell 12 and the end cover 14, the guide column 13 slides from one end to the other end along the arc-shaped groove wall of the guide hole 141, thereby facilitating the rotational guidance of the rotating buckle.

[0064] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
