Description

Technical Field

[0001] This invention relates to the field of sliding doors and windows, and particularly to a lock body, lock body assembly, and sliding door / window for sliding doors and windows. Background Technology

[0002] Sliding doors and windows are widely used in daily life. As an essential decorative element in modern home décor, their sliding mechanism significantly improves the utilization of interior space compared to ordinary rotating doors and windows. However, since most sliding doors and windows cannot be fully opened, limiting passageway space, people desire a combination of sliding and casement / rotating doors and windows, enabling both partially open sliding and fully open rotating doors and windows. To achieve a fully open sliding and rotating door and window, the sliding track consists of two parts: a fixed track fixed to the upper part of the door / window frame and a movable track fixed to the top of the fixed door / window frame. Since the sliding door and window must slide from the fixed track to the movable track to overlap and rotate, a special locking mechanism must be designed on both the fixed and movable tracks to ensure smooth sliding between them.

[0003] Chinese patents CN214996814U and CN110905300A both disclose a lock body suitable for this type of door and window. These lock bodies include a fixed lock body and a movable lock body that are compatible with each other. The lock bodies are respectively provided with a sliding bolt, a positioning rod, and a positioning rod groove. Through mutual cooperation, they can solve most of the functional requirements of this type of door and window. However, the inventors learned from market practice and interviews that this type of door and window has another important defect that seriously affects the user experience of consumers.

[0004] The unique feature of this type of door and window is its ability to open and slide. Existing locking devices address the engagement and disengagement of the moving and fixed tracks in key areas of the door. This action requires manual pushing, which demands a certain skill. Specifically, when opening and closing the door, the user must manually manage the door's inertial force. If this inertial force is not controlled, when the moving track on the door and the fixed track on the door frame engage with the locking device, the door's inertia can cause it to rebound, disengaging the positioning rod from its groove. This results in the door not engaging properly and failing to slide as designed, especially for beginners who often experience difficulties. Consumer feedback suggests that this type of door is immature and unusable, severely impacting sales and market share.

[0005] Therefore, there is an urgent need to provide a lock body, lock body assembly, and sliding door / window for sliding doors and windows to solve the above problems. Summary of the Invention

The movable lock body is any of the sliding door and window lock bodies described in the above invention. The movable lock body is also provided with a sliding latch groove, and a sliding latch is telescopically provided in the sliding latch groove.

[0025] Unlike existing technologies, the above technical solution achieves the following beneficial effects: (1) This invention is easy to operate and avoids inertial rebound. This invention achieves automatic locking after the movable lock body and the fixed lock body are coupled through the sequential linkage of the positioning rod, the stop slider, the locking slider and the rotating mechanism. The user only needs to push the door to the coupling position, and no additional skills are required to control the inertial force to complete the reliable locking. This completely avoids the problem of track separation and door unable to be pushed or pulled normally due to inertial rebound, and significantly improves the user experience.

[0026] (2) The coupling and decoupling logic of this invention is clear and the operation is reliable. During coupling, the positioning rod compresses the stop slider, and after the positioning rod passes, the return spring drives each slider to reset. At the same time, the locking slider is locked by the blocking surface of the rotating mechanism, thus achieving self-locking. During decoupling, it is only necessary to push or pull the door leaf to make the door leaf contact point or the sliding roller trigger the rotating mechanism to rotate. The rotating mechanism switches to the decoupling surface, and then it can be separated with a little force. The entire operation process is highly automated and requires no manual judgment or additional operation.

[0027] (3) The present invention has a compact structure and high integration. The present invention integrates positioning, stopping, locking, and rotation triggering functions into the same lock body, with fewer parts and less space occupied. Through the ingenious cooperation between the contact surface and the inclined surface, the linear motion of the slider is converted into the rotational motion of the rotating mechanism, resulting in a sophisticated structure and high reliability.

[0028] (4) The present invention has a wide range of applications and can be flexibly configured. By setting different installation methods for the stop slider and the locking slider, the lock body can adapt to different installation spaces and driving requirements. It can be used for both moving track ends and fixed track ends, and has strong versatility. Attached Figure Description

[0031] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0032] like Figures 1 to 19 As shown, this embodiment provides a lock body for sliding doors and windows. The lock body 1 has a hanging rail slide 101. On one side of the hanging rail slide 101, the lock body has a positioning rod groove 102 and a stop slider groove 103. The positioning rod groove 102 has a stop slider 104. The stop slider is telescopically disposed in the stop slider groove 103. The lock body 1 near the stop slider 104 is also provided with a rotating mechanism 201 adapted to the stop slider. The stop slider 104 or the rotating mechanism 201 is telescopically provided with a locking slider 115.

[0033] In this embodiment, the lock body 1 can be used in sliding doors and windows that can be pushed, pulled, and rotated to fully open. It can be a movable lock body 301 or a fixed lock body 302 for such doors and windows. The lock body itself has relevant existing structures, such as the sliding bolt included in the movable lock body, and the positioning rod included in the lock body coupled and adapted to this lock body. In specific use, the stop slider is telescopically set in the stop slider groove 103. A return spring can be set in the stop slider groove 103. The stop slider is telescopically set in the stop slider groove 103 through the return spring. Similarly, the locking slider 115 can also be set on the stop slider or the rotating mechanism 201 through the return spring. In the following embodiments, the telescopic setting mentioned can be realized by a return spring or other resettable structure, which will not be described in detail below.

[0034] In practical use, such as Figures 20 to 33 As shown, through the cooperation of the positioning rod adapted to the lock body 1 and the positioning rod groove 102, stop slider, rotating mechanism 201, locking slider 115, and return spring of the lock body, the positioning rod and stop slider are locked and released, thereby realizing automatic locking after the two lock bodies are coupled. The user only needs to push the door leaf 310 to the coupling position, and no additional skills are required to control the inertial force to complete the reliable locking. This completely avoids the problem of track separation and door leaf 310 being unable to be pushed and pulled normally due to inertial rebound, and significantly improves the user experience.

[0035] like Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment, the rotating mechanism 201 includes a rotating base 202 and a rotating block 203. The rotating block 203 is rotatably connected to the rotating base 202. The rotating block 203 is provided with a first contact surface 204, and the stop slider is provided with a first contact surface 107. The first contact surface 107 is adapted to be connected to the first contact surface 204. In the specific implementation of this embodiment, when the stop slider is compressed and moves downward, the first contact surface 107 on the stop slider will contact the first contact surface 204 on the rotating block 203. In this embodiment, both the first contact surface 107 and the first contact surface 204 are inclined surfaces. Under the action of the inclined surfaces, the rotating block 203 will be driven outward (rotating towards the side of the hanging rail slide 101).

[0036] like Figure 9 , Figure 11 , Figure 12 and Figure 19 As shown, in this embodiment, the locking slider 115 is telescopically mounted on the rotating block 203. The locking slider 115 has a second contact surface 116, and the stop slider has a locking hole 108 adapted to the locking slider 115. The inner wall of the locking hole 108 has a second contact surface 205 adapted to and connected to the second contact surface 116. In the specific implementation of this embodiment, when the lock body and the coupling lock body are engaged, the stop slider on the lock body is compressed downward under the action of the positioning rod on the coupling lock body. During the compression process, the first contact surface 107 contacts the first contact surface 204 and drives the rotating block 203 to rotate outward. During this process, the locking slider is compressed into the rotating block under the pressure of the side of the stop slider. The position corresponding to the locking slider is located at... Figure 12The positioning rod is positioned above the locking hole 108 and not at the second contact surface 205. When the positioning rod passes the stop slider, the stop slider quickly resets under the action of the return spring. At this time, the locking slider 115 on the rotating block 203 is quickly ejected under the action of the return spring and matches the locking hole 108 on the stop slider, thereby locking the stop slider. This prevents the stop slider from rebounding and being pressed down under the inertia of the positioning rod, thus limiting the positioning rod to the area formed by the positioning rod groove 102 and the stop slider, and preventing the positioning rod from being ejected due to inertial force. When decoupling of the lock body is required, the door leaf, during the pulling process, causes the rotating block to reset due to contact with the door leaf contact point or the sliding roller, i.e., it turns away from the side of the hanging rail slide. At this time, the locking slider is located below the second contact surface 205. When the door leaf is pulled, causing the positioning rod to move out of the positioning rod groove, the positioning rod presses down on the stop slider. This causes the locking slider to move out of the locking hole under the cooperation of the second contact surface 116 and the second contact surface 205 of the stop slider. Under the pressure of the side of the stop slider, the locking slider is compressed into the rotating block. At this time, the decoupling operation of this lock body and the coupled lock body with it can be achieved. In this embodiment, the braking slider pressing down will drive the rotating block to rotate outward. During the decoupling process, the locking slider disengaging from the locking hole through the first contact surface occurs before the rotating block rotates. Specifically, this can be achieved by increasing the distance time between the first contact surface and the first contact surface, i.e., increasing the contact interval between the first contact surface and the first contact surface. In this embodiment, the locking hole 108 is provided in the form of a hole or slot. Furthermore, the locking hole 108 has a lateral width for the rotating block 203 to rotate, so that when the rotating block 203 rotates, the locking hole 108 can provide a lateral movement distance for the locking slider 115. In addition, the second contact surface 205 provided on the inner wall of the locking hole 108 can be a portion of the locking hole 108 in the lateral direction; that is, the locking slider 115 can only be engaged and driven when it moves to the position where the second contact surface 205 is provided. In this embodiment, the second contact surface 205 provided on the inner wall of the locking hole 108 is located on the lateral side of the locking hole 108 away from the hanging rail slide 101.

[0037] like Figure 6 and Figure 7 , Figures 13 to 19 As shown, in different embodiments, the locking slider 115 is telescopically mounted on the stop slider, and the locking slider 115 is provided with a second contact surface 116. The rotating block 203 is provided with a second contact surface 205, and the second contact surface 205 is adapted to be connected with the second contact surface 116. In some embodiments, such as Figure 14 As shown, the rotating block 203 is provided with a step 206, and the second contact surface 205 is provided on the side of the step 206 near the stop slider.

[0038] like Figure 7, Figure 13 , Figures 15 to 19 As shown, in some embodiments, the stop slider 104 includes a first stop slider 105 and a second stop slider 106, and a first contact surface 107 is disposed on the first stop slider 105.

[0039] like Figure 7 , Figure 13 , Figures 15 to 19 As shown, the locking slider 115 is telescopically mounted on the second stop slider 106. The bottom of the locking slider 115 has a second contact surface 116, and the rotating block 203 has a second contact surface 205. The second contact surface 205 is adapted to and connected with the second contact surface 116. The top of the locking slider 115 has a third contact surface 117, and the first stop slider 105 has a third contact surface 110, which is adapted to and connected with the third contact surface 117. The first stop slider 105 has an extension 109 on the side near the locking slider 115, and the third contact surface 110 is located on the extension 109. The extension 109 has a fourth contact surface 112, and the second stop slider 106 has a fourth contact surface 111 adapted to the fourth contact surface 112. The rotating block 203 has a first blocking surface 207, and the locking slider 115 has a first blocking surface 118 adapted to the first blocking surface 207.

[0040] Combination Figures 20 to 33 The following will use the lock body in the above embodiment as the movable lock body 301 and the coupling lock body that cooperates with it as the fixed lock body 302 to illustrate the cooperation principle and process of the above embodiment.

[0041] Example 1: When the movable lock body 301 and the fixed lock body 302 are separated and not coupled, the state between the various parts is as follows: (1) The movable lock body 301 and the fixed lock body 302 are separate.

[0042] (2) The sliding bolt 304 on the movable lock body 301 will block the sliding rail due to the return spring, and the sliding roller 311 will not be able to slide normally in the track, thereby locking the door leaf 310 and achieving the design requirements.

[0043] (3) The positioning rod 305 on the fixed lock body 302 is far away from its mating object and has no mating action.

[0044] (4) The first stop slider 105 will return to the highest position because of the return spring.

[0045] (5) The second stop slider 106 will also return to the highest position because of the return spring.

[0046] (6) The locking slider 115 will protrude from the slot of the locking slider 115 because of the return spring.

[0047] (7) The rotating mechanism 201 will most likely rotate to the second stop slider 106, and there is a small probability that it will be in other positions. It has been specially designed and will not affect other coordination.

[0048] (8) The door leaf 310 contact point (not shown) or sliding roller 311 is locked because the sliding lock tongue 304 blocks the hanging rail slide 101, so the movable door leaf 310 cannot touch the rotating mechanism 201.

[0049] At this point, all components are relatively stationary and stable.

[0050] Example 2: When the movable lock body 301 and the fixed lock body 302 move relative to each other and gradually couple, this action is divided into the following steps and scenarios in chronological order.

[0051] I. During the relative movement and gradual coupling of the movable lock body 301 and the fixed lock body 302, when the positioning rod 305 just touches the first stop slider 105 and continues to move forward until the first stop slider 105 is fully compressed to its lowest position, the states and movements of the other components are detailed below: (1) The movable lock body 301 and the fixed lock body 302 are about to be fully coupled.

[0052] (2) The sliding latch 304 has not yet touched the positioning rod 305, so the sliding latch 304 has not changed.

[0053] (3) The positioning rod 305 touches the first stop slider 105 and continues to compress the first stop slider to the lowest end.

[0054] (4) The first stop slider 105 begins to slide downwards. This process involves two actions: First, the first stop slider 105 slides downwards to half its travel distance, at which point its third contact surface 110 engages with the third contact surface 117 of the locking slider 115, compressing the locking slider 115 inwards and maintaining it in place. Second, the first stop slider 105 continues to slide downwards from the halfway point, at which point its first contact surface 107 engages with the first contact surface 204 of the rotating mechanism 201, changing the force in the up-and-down direction of the first stop slider 105 into the force in the rotation direction of the rotating mechanism 201. This causes the rotating mechanism 201 to rotate away from the second stop slider 106, and simultaneously causes the first blocking surface 207 of the rotating mechanism 201 to rotate to prevent the locking slider 115 from protruding further from the second stop slider 106 and moving downwards. This action is divided into two steps to reduce mutual interference and ensure smooth operation of the entire process.

[0055] (5) The second stop slider 106 has not yet come into contact with the positioning rod 305 and there is no direct change. However, the locking slider 115 embedded in the second stop slider 106 is compressed to the innermost end of the locking slider 115 groove because the third contact surface 117 on the locking slider 115 cooperates with the third contact surface 110 of the first stop slider 105. At this time, the second stop slider 106 can move up and down without obstruction because the locking slider 115 does not protrude from the surface of the second stop slider 106; or the locking slider 115 is compressed into the cavity of the second stop slider 106 because the third contact surface 117 cooperates with the third contact surface 110 of the first stop slider 105. At this time, the second stop slider 106 can move up and down without obstruction because the locking slider 115 does not protrude from the surface of the second stop slider 106.

[0056] (6) The rotating mechanism 201 rotates to one end away from the second stop slider 106, and at the same time the first blocking surface 207 of the rotating mechanism 201 rotates to prevent the locking slider 115 from protruding again, and the second stop slider 106 moves downward.

[0057] (7) The door leaf 310 contact point or sliding roller 311 is locked because the sliding lock tongue 304 blocks the hanging rail slide 101, so the movable door leaf 310 cannot touch the rotating mechanism 201.

[0058] II. During the relative movement and gradual coupling of the movable lock body 301 and the fixed lock body 302, when the positioning rod 305 has fully compressed the first stop slider 105 to its lowest point and begins to compress the second stop slider 106 to its lowest point, the states and movements of the other components are detailed below: (1) The movable lock body 301 and the fixed lock body 302 are about to be fully coupled.

[0059] (2) The sliding latch 304 is about to be compressed to the innermost end by the positioning rod 305. In this embodiment, the sliding latch 304 is provided with a touched branch 306. The positioning rod 305 cooperates with the touched branch 306 to compress the sliding latch 304, and the hanging rail slide 101 is about to be fully opened.

[0060] (3) The positioning rod 305 has fully compressed the first stop slider 105 to the lowest end, and begins to compress the second stop slider until it reaches the lowest end.

[0061] (4) The first stop slider 105 is already at the lowest position, and its state is the same as described above, with no change.

[0062] (5) The second stop slider 106 is gradually squeezed downward under the pressure of the positioning rod 305. Since the locking slider 115 has been squeezed into the cavity of the second slider due to the previous action, the surface of the second slider is smooth and unobstructed, and it can move freely up and down. Therefore, the second stop slider 106 will slide down to the lowest point, allowing the positioning rod 305 to pass smoothly.

[0063] (6) Locking slider 115 is located in the cavity of the second stop slider 106.

[0064] (7) The rotating mechanism 201 rotates to one end away from the second stop slider 106, and at the same time the first blocking surface 207 of the rotating mechanism 201 rotates to prevent the locking slider 115 from protruding from the second stop slider 106 and moves downward.

[0065] (8) The door leaf 310 contact point or sliding roller 311 is locked because the sliding lock tongue 304 blocks the hanging rail slide 101, so the movable door leaf 310 cannot touch the rotating mechanism 201.

[0066] III. During the relative movement and gradual coupling of the movable lock body 301 and the fixed lock body 302, the positioning rod 305 has moved to the second stop slider 106 and completely passed through the second stop slider 106. At this time, the state and movement of the other components are detailed as follows: (1) The movable lock body 301 and the fixed lock body 302 are fully coupled.

[0067] (2) The sliding latch 304 is compressed to its innermost end by the positioning rod 305, the hanging rail slide 101 is fully opened, and the sliding wheel 311 moves freely in the hanging rail slide 101. The sliding wheel 311 can slide from the movable track to the fixed track 309, or from the fixed track 309 to the movable track 308.

[0068] (3) The positioning rod 305 has fully compressed the second stop slider 106 to the lowest position and passed through the compression position. The second stop slider 106 will return to the highest position and be locked due to the return spring and design, thus completely preventing the positioning rod 305 from returning.

[0069] (4) The first stop slider 105 will return to the highest position due to the return spring, thereby releasing the locking slider 115. The locking slider 115 will protrude the second stop slider 106. At this time, the second stop slider 106 will be jammed due to the interference between the first blocked surface 118 of the locking slider 115 and the first blocking surface 207 of the rotating mechanism 201, and will be unable to slide up and down, thereby locking the positioning rod 305 to achieve the purpose of locking the movable lock body 301, so that the movable lock body 301 and the fixed lock body 302 are completely coupled and cannot be decoupled.

[0070] (5) The second stop slider 106 will be reset to the highest position due to the return spring. Also, because the locking slider 115 has protruded from the second stop slider 106, and because the locking slider 115 inside the second stop slider 106 interferes with the first blocking surface 207 of the rotating mechanism 201, the second stop slider 106 will be stuck and unable to slide up and down, thereby locking the positioning rod 305 to achieve the purpose of locking the movable lock body 301, so that the movable lock body 301 and the fixed lock body 302 are completely coupled and cannot be decoupled.

[0071] (6) The locking slider 115 protrudes from the second stop slider 106 and interferes with the first blocking surface 207 of the rotating mechanism 201, thus jamming the second stop slider 106.

[0072] (7) The rotating mechanism 201 rotates to one end away from the second stop slider 106, and at the same time the first blocking surface 207 of the rotating mechanism 201 rotates to prevent the locking slider 115 from moving downward when protruding the second stop slider 106.

[0073] (8) Because the movable lock body 301 and the fixed lock body 302 are fully coupled, the sliding rail 101 is completely unobstructed, the movable door leaf 310 can slide freely, and the door leaf 310 contact point or sliding wheel 311 can touch the rotating mechanism 201 at any time.

[0074] At this point, the coupling action is fully completed, and the movable lock body 301 and the fixed lock body 302 are fully coupled and cannot be decoupled.

[0075] Example 3, the decoupling process is as follows: 1. Due to the above actions, the movable lock body 301 and the fixed lock body 302 are fully coupled. At this time, the sliding roller 311 can slide freely within the sliding rail 101, and the door leaf 310 contact point or the sliding roller 311 can contact the rotating mechanism 201 at any time to complete the key action of decoupling. Therefore, when we push or pull the door leaf 310, the door leaf 310 contact point or the sliding roller 311 can contact the rotating mechanism 201. The action states of each component at this time are as follows: (1) The movable lock body 301 and the fixed lock body 302 are still fully coupled, but not stuck. They are in a decoupled state.

[0076] (2) The sliding latch 304 is compressed to its innermost end by the positioning rod 305, the hanging rail slide 101 is fully opened, and the sliding wheel 311 moves freely in the hanging rail slide 101. The sliding wheel 311 can slide from the movable track to the fixed track 309, or from the fixed track 309 to the movable track 308.

[0077] (3) Positioning rod 305 is in a fully coupled state, but not in a jammed state; it is in a decoupled state.

[0078] (4) The first stop slider 105 will be reset to the highest position due to the reset spring.

[0079] (5) The second stop slider 106 will return to its highest position due to the return spring. The locking slider 115 protrudes from the second stop slider 106, but because the rotating mechanism 201 has been touched by the door leaf 310 contact point or the sliding roller 311 and rotated to a position close to the second stop slider 106, the first blocking surface 207 of the rotating mechanism 201 can no longer prevent the locking slider 115 and the second stop slider 106 from moving down as a whole. When the second stop slider 106 moves down, the second contact surface 205 of the rotating mechanism 201 and the second contact surface 116 on the locking slider 115 will cooperate, and the locking slider 115 will be squeezed into the cavity of the second stop slider 106. At this time, the second stop slider 106 can slide up and down, and the positioning rod 305 cannot be completely locked. Now the force that locks the positioning rod 305 comes entirely from the return spring of the second stop slider 106.

[0080] (6) The locking slider 115 protrudes from the second stop slider 106 and cooperates with the second contact surface 205 of the rotating mechanism 201. When squeezed, it will be recompressed into the cavity of the second stop slider 106 and can no longer lock the second stop slider 106.

[0081] (7) The rotating mechanism 201 rotates to one end close to the second stop slider 106, and at the same time the second contact surface 205 of the rotating mechanism 201 rotates to cooperate with the second contact surface 116 of the locking slider 115. The locking slider 115 will be compressed back into the cavity of the second stop slider 106 when it is squeezed.

[0082] (8) The door leaf 310 contact point or the sliding roller 311 has already touched the rotating mechanism 201 and cannot touch the rotating mechanism 201 again. It needs to wait until the next decoupling cycle to touch the rotating mechanism 201.

[0083] At this time, as long as the door leaf 310 is subjected to force, that is, as long as the force is greater than the spring force of the return spring of the second stop slider 106, the movable lock body 301 and the fixed lock body 302 will immediately decouple.

[0084] 2. When the door is opened by force, the movable lock body 301 and the fixed lock body 302 immediately decouple. The decoupling process is as follows: (1) The movable lock body 301 and the fixed lock body 302 are immediately and smoothly decoupled.

[0085] (2) After decoupling, the sliding lock tongue 304 is not squeezed and will be reset by its return spring into the hanging rail slide 101, thereby preventing the sliding wheel 311 from sliding. Therefore, the sliding wheel 311 cannot slide freely in the track at this time.

[0086] (3) The positioning rod 305 will first touch and compress the second stop slider 106. After passing the second stop slider 106, it will then compress the first stop slider 105 and pass through the first stop slider 105. There is a cooperating movement when compressing the second stop slider 106 and the second stop slider 106. The movement is as follows: under the cooperation of the fourth contact surface 111 of the second stop slider 106 and the fourth contact surface 112 of the first stop slider 105, the first stop slider 105 begins to slide downward. There are two cooperating actions in this process. First: the first stop slider 105 slides downward from the beginning to the position where it travels halfway. Its third contact surface 110 cooperates with the third contact surface 117 of the locking slider 115 to compress the locking slider 115 inward. Second: The first stop slider 105 continues to slide downward from half position. Its first contact surface 107 and the first contact surface 204 of the rotating mechanism 201 cooperate to change the force in the up-down movement direction of the first stop slider 105 into the force in the rotation direction of the rotating mechanism 201, thereby causing the rotating mechanism 201 to rotate away from the second stop slider 106. At the same time, the rotating mechanism 201 rotates to a position that can prevent the locking slider 115 from protruding from the second stop slider 106 and moving downward.

[0087] (5) After the second stop slider 106 is compressed and the positioning rod 305 passes through, the reset spring helps to reset, preparing for the next coupling.

[0088] (6) Locking slider 115 will be compressed first and then reset to prepare for the next coupling.

[0089] (7) The rotating mechanism 201 rotates to one end away from the second stop slider 106 to prepare for the next coupling.

[0090] (8) Door leaf 310 contact point or sliding hanger 311 Because the sliding hanger 311 cannot slide freely, it cannot touch the rotating mechanism 201.

[0091] The above describes the coupling and decoupling process of the lock body and the coupling lock body as illustrated in the above embodiments. Figures 24 to 28 As shown, the coupling and decoupling process of using this lock body as the fixed lock body 302 and the lock body that cooperates with it as the movable lock body 301 is basically the same as the above principle and process. The difference is that the positioning rod 305 and the sliding lock tongue 304 are set on the coupling lock body (movable lock body 301), the positioning rod groove 102 and the stop slider 104 are set on the fixed lock body 302, and the cooperating objects are also adjusted accordingly.
