Description
Technical Field
[0001] This utility model relates to the field of door and window control hardware, and in particular to a multi-point integrated lock body and lock. Background Technology
[0002] With societal development, people are increasingly aware of security in their homes, businesses, and other establishments. Traditional single-point locks are proving insufficient in their anti-theft performance against increasingly diverse burglary methods. Multi-point integrated locks, by setting multiple locking points at different locations on the door, significantly increase the difficulty of prying open the door, effectively enhancing security levels and meeting people's demand for high-security locks.
[0003] Currently, multi-point interlocking locks generally consist of a main lock body, auxiliary lock bodies, a panel, and a transmission rod. By manually or automatically rotating the main lock body, the internal motion structure converts the rotational motion into linear motion, which is then transmitted to the auxiliary lock bodies at both ends by the transmission rod, thereby controlling the extension and retraction of the auxiliary lock bodies and realizing the operation of the entire multi-point interlocking lock. However, due to structural limitations, the transmission rods of current multi-point interlocking locks are often disconnected at both ends of the main lock body and the ends of the auxiliary lock bodies. That is, each of the auxiliary lock bodies at both ends needs to be connected to a transmission rod. If it is necessary to add locking points at the outer end of the auxiliary lock bodies, additional transmission rods are required. The added locking points need to be indirectly connected to the main lock body through the auxiliary lock bodies, but there will inevitably be gaps between the connection points, which will increase the transmission error. The connection gaps will accumulate, and the more locking points are connected, the greater the accumulated error will be. Utility Model Content

Detailed Implementation
[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0039] Reference Figures 1 to 14The diagram illustrates an embodiment of the multi-point integrated lock body of this utility model. The multi-point integrated lock body includes a lock body 1 and a transmission rod 2. The lock body 1 includes a main lock body 11 and at least one secondary lock body 12. The main lock body 11 includes a drive assembly 111, and the secondary lock body 12 includes a driven assembly 121. The transmission rod 2 is located on one side of the main lock body 11 and the secondary lock body 12, and is connected to the main lock body 11 and extends towards each secondary lock body 12. The transmission rod 2 is connected to the drive assembly 111 and the driven assembly 121. The drive assembly 111 drives the transmission rod 2, which in turn drives the driven assembly 121.
[0040] Specifically, a multi-point integrated lock body is a special lock structure that connects to the door frame through multiple locking points. When opening or locking the door, the user only needs one operation (such as turning the key or handle) to control multiple locking points simultaneously, which is convenient to operate and improves the security and stability of the lock on the door.
[0041] The multi-point integrated lock body includes a lock body 1 and a transmission rod 2. The lock body 1 is used to lock or open the door. The lock body 1 includes a main lock body 11 and at least one secondary lock body 12. The main lock body 11 is the core part of the multi-point integrated lock body, and the user's main operation is applied to the main lock body 11. The main lock body 11 includes a drive assembly 111, which is used to provide power to extend or retract the bolt 15 of the main lock body 11. The secondary lock body 12 works together with the main lock body 11 to lock or open the door. The number of secondary lock bodies 12 can be configured according to actual needs, but the multi-point integrated lock body includes at least one secondary lock body 12. Each secondary lock body 12 includes a driven assembly 121, which is used to provide power to extend or retract the bolt 15 of the secondary lock body 12. The driven assembly 121 is connected to the drive assembly 111 of the main lock body 11 through the transmission rod 2, thereby realizing the synchronous operation of the main lock body 11 and the secondary lock body 12.
[0042] The transmission rod 2 is used to transmit power to achieve the synchronous extension or retraction of the latches 15 of the main lock body 11 and the auxiliary lock body 12. The transmission rod 2 is located on one side of the main lock body 11 and the auxiliary lock body 12, and the transmission rod 2 is connected to the main lock body 11 and extends towards each auxiliary lock body 12. That is, the length of the transmission rod 2 extends to the location of the main lock body 11 and all the auxiliary lock bodies 12, thereby connecting the main lock body 11 and each auxiliary lock body 12. At the same time, the transmission rod 2 is connected to the drive assembly 111 of the main lock body 11, and the transmission rod 2 is also connected to the driven assembly 121 of each auxiliary lock body 12, thereby ensuring that the power of the main lock body 11 can be smoothly transmitted to each auxiliary lock body 12, so as to achieve the synchronous action of the main lock body 11 and all the auxiliary lock bodies 12.
[0043] When a user locks or unlocks the main lock body 11, the drive assembly 111 starts working, generating a main driving force. On one hand, the main driving force is transmitted to the bolt 15 of the main lock body 11, thereby controlling the bolt 15 to extend or retract, thus locking or unlocking the main lock body 11. On the other hand, the main driving force is transmitted to the transmission rod 2, thereby driving the transmission rod 2 to move. Furthermore, the transmission rod 2 drives the driven assemblies 121 of all the secondary lock bodies 12 to move, thereby causing the driven assemblies 121 to generate a secondary driving force. This secondary driving force is transmitted to the bolt 15 of the secondary lock bodies 12, thereby controlling the bolt 15 to extend or retract, thus locking or unlocking each secondary lock body 12. Finally, the locking or unlocking actions of the main lock body 11 and all the secondary lock bodies 12 are realized synchronously.
[0044] More specifically, refer to Figure 4 As shown, the transmission rod 2 is an integral structure to improve the structural stability of the transmission rod 2 and further reduce the cumulative transmission error of multiple locking points.
[0045] More specifically, in addition to passing through and connecting the main lock body 11 and extending into and connecting with each secondary lock body 12, the transmission rod 2 can also pass through and connect to the main lock body 11 and extend into and through each secondary lock body 12, thereby connecting with other types of locking points outside the secondary lock body 12 to improve the practicality of the transmission rod 2.
[0046] This application connects the transmission rod 2 to the main lock body 11 and extends it toward the location of each auxiliary lock body 12. The transmission rod 2 is also connected to the drive assembly 111 and each driven assembly 121, so that one transmission rod 2 can connect the main lock body 11 and each auxiliary lock body 12. This allows each auxiliary lock body 12 to be directly connected to the main lock body 11 through the same transmission rod 2, thereby reducing the cumulative transmission error of all locking points and improving the transmission accuracy of the multi-point integrated lock body.
[0047] For example, refer to Figure 1As shown, the lock body 1 includes a main lock body 11, two auxiliary lock bodies 12, and a transmission rod 2. The two auxiliary lock bodies 12 are located on both sides of the main lock body 11, and the main lock body 11 and the two auxiliary lock bodies 12 are arranged vertically. The transmission rod 2 passes through the main lock body 11 and is fixedly connected to the drive assembly 111 of the main lock body 11. Both ends of the transmission rod 2 extend toward the two auxiliary lock bodies 12 and are fixedly connected to the driven assemblies 121 of the two auxiliary lock bodies 12. Therefore, when the drive assembly 111 drives in a certain direction, it can drive the transmission rod 2 to drive in the same direction, thereby driving the driven assemblies 121 of the two auxiliary lock bodies 12 to drive in the same direction. Thus, the synchronous transmission of the drive assembly 111 and the two driven assemblies 121 is achieved, so that the main lock body 11 and the two auxiliary lock bodies 12 can lock or unlock synchronously, improving the ease of operation of the multi-point integrated lock body, reducing the cumulative transmission error of the multi-point integrated lock body, and improving the transmission accuracy.
[0048] In a specific embodiment, the drive assembly 111 has a first drive part (not shown in the figure) on the side facing the transmission rod 2, and the transmission rod 2 has a first connecting part on the side facing the drive assembly 111. The first connecting part is fixedly connected to the first drive part. Specifically, the transmission rod 2 is connected to the main lock body 111 and extends towards each auxiliary lock body 121. To ensure the connection between the transmission rod 2 and the main lock body 111, a first driving part is provided on the drive assembly 111 of the main lock body 111. The first driving part is used to drive the transmission rod 2 to move and is located at one end of the drive assembly 111 facing the transmission rod 2. The transmission rod 2 is provided with a first connecting part, which is used to fix the drive assembly 111 and the transmission rod 2. The first connecting part is located on the side of the transmission rod 2 facing the drive assembly 111, and the first driving part is fixedly connected to the first connecting part, thereby fixing the drive assembly 111 and the transmission rod 2. When the drive assembly 111 moves, it drives the transmission rod 2 to move, and the transmission rod 2 then drives each driven assembly 121 to move, thereby realizing the linkage between the main lock body 111 and each auxiliary lock body 121. The connection method between the drive assembly 111 and the transmission rod 2 in this embodiment is simple.
[0049] In one embodiment, reference is made to Figure 2 , Figure 4 , Figure 5 , Figure 10As shown, the first driving part includes a first protrusion 1111, which protrudes outward from one end of the first driving part. The first connecting part includes a first port 21, which engages with the first protrusion 1111. Specifically, the connection between the transmission rod 2 and the drive assembly 111 may be achieved by threaded connection, snap-fit connection, or other reliable connection methods to ensure the stability and reliability of the connection. In this embodiment, the transmission rod 2 and the drive assembly 111 are connected by snap-fit. The first drive part includes a first protrusion 1111, which is formed by the first drive part protruding towards the transmission rod 2 from one end near the transmission rod 2. The first connecting part includes a first through-hole 21, which is correspondingly provided with the first protrusion 1111. When assembling the transmission rod 2 and the main lock body 11, the first protrusion 1111 is inserted into the first through-hole 21 so that the first protrusion 1111 is snapped into the first through-hole 21, thereby achieving a fixed connection between the transmission rod 2 and the drive assembly 111. When the drive assembly 111 works, the drive assembly 111 moves, which on the one hand drives the locking tongue 15 of the main lock body 11 to move, and on the other hand drives the transmission rod 2 to move, so as to transmit the driving force generated by the drive assembly 111 to the transmission rod 2.
[0050] In this embodiment, the drive assembly 111 and the transmission rod 2 are connected by a snap-fit method, which is simple, reliable, and provides high transmission stability.
[0051] In a specific embodiment, refer to Figure 7 , Figure 8 , Figure 10As shown, the first connecting part also includes a first engaging part 22 disposed adjacent to the first opening 21. The first engaging part 22 protrudes from one side of the transmission rod 2 toward the main lock body 11. The first driving part also includes a first slot 1112 disposed adjacent to the first protrusion 1111. The first slot 1112 is formed by one side of the driving assembly 111 being recessed inward. The first slot 1112 engages with the first engaging part 22. Specifically, the first connecting part further includes a first engaging part 22, which is adjacent to the first through-hole 21. The first engaging part 22 protrudes outward from the side of the transmission rod 2 near the main lock body 11 towards the main lock body 11. The first driving part further includes a first slot 1112, which is adjacent to the first protrusion 1111. The first slot 1112 is formed by the inward recess of the driving assembly 111 towards the transmission rod 2. The first slot 1112 and the first engaging part 22 are adapted to each other and are correspondingly arranged. Assembly transmission When the rod 2 and the main lock body 11 are connected, the first protrusion 1111 is embedded in the first through-hole 21 and engages with the first through-hole 21. At the same time, the first engaging part 22 is embedded in the first slot 1112 and engages with the first slot 1112, thereby further improving the fixing stability and transmission stability of the transmission rod 2 and the drive assembly 111. After assembly, the first engaging part 22 and the first protrusion 1111 are adjacent, and the first engaging part 22 is located on one side of the first protrusion 1111, thereby increasing the overlap size of the transmission rod 2 and the drive assembly 111 and improving the connection stability of the transmission rod 2 and the drive assembly 111.
[0052] More specifically, in this embodiment, the first connecting part includes two first engaging parts 22, and the first driving part includes two first slots 1112. The two first engaging parts 22 are respectively located on both sides of the first opening 21, and the two first slots 1112 are respectively located on both sides of the first protrusion 1111. When assembling the transmission rod 2 and the main lock body 11, the two first engaging parts 22 and the two first slots 1112 engage with each other and further limit the two sides of the first protrusion 1111, thereby improving the stability of the connection between the transmission rod 2 and the main lock body 11, so that the driving assembly 111 drives the transmission rod 2 with higher stability.
[0053] Furthermore, referring to Figure 8 , Figure 10As shown, the groove wall at the end of the first slot 1112 away from the first protrusion 1111 is set as an inclined structure, and the side of the first engaging part 22 away from the first opening 21 is also set as an inclined structure. When assembling the transmission rod 2 and the main lock body 11, the groove wall at the end of the first slot 1112 away from the first protrusion 1111 abuts against the side of the first engaging part 22 away from the first opening 21, and the side of the first engaging part 22 away from the first opening 21 slides downward along the inclined direction of the groove wall at the end of the first slot 1112 away from the first protrusion 1111 until the first engaging part 22 is embedded in the first slot 1112. In this embodiment, the groove wall at the end of the first slot 1112 away from the first protrusion 1111 is set as an inclined structure, and the side of the first engaging part 22 away from the first opening 21 is set as an inclined structure, so as to guide the sliding of the first engaging part 22, thereby improving the smoothness of the sliding of the first engaging part 22 and improving the assembly efficiency.

When the driving component 111 moves, it drives the transmission rod 2 to move, and the transmission rod 2 then drives each driven component 121 to move, thereby realizing the linkage between the main lock body 111 and each secondary lock body 121. The connection method between the driven component 121 and the transmission rod 2 in this embodiment is simple.
[0055] In one embodiment, reference is made to Figure 3 , Figure 4 , Figure 6 , Figure 11As shown, the second driving part includes a second protrusion 1211, which protrudes outward from one end of the second driving part. The second connecting part includes a second through-hole 23, which engages with the second protrusion 1211. Specifically, each secondary lock body 12 includes a driven component 121. The connection between the transmission rod 2 and the driven component 121 may be a threaded connection, a snap-fit connection, or other reliable connection methods to ensure the stability and reliability of the connection. In this embodiment, the transmission rod 2 and the driven component 121 are connected by a snap-fit method.

At the same time, the second engaging part 24 is embedded in the second slot 1212 and engages with the second slot 1212, thereby further improving the fixing stability and transmission stability of the transmission rod 2 and the driven component 121. After assembly, the second engaging part 24 and the second protrusion 1211 are adjacent to each other, and the second engaging part 24 is located on one side of the second protrusion 1211, thereby increasing the overlap size of the transmission rod 2 and the driven component 121 and improving the connection stability of the transmission rod 2 and the driven component 121.
[0058] More specifically, in this embodiment, the second connecting part includes two second engaging parts 24, and the second driving part includes two second slots 1212.

The lock body panel 3 extends along the length direction of the transmission rod 2. The lock body panel 3 is connected to the main lock body 11 and the auxiliary lock body 12, and the lock body panel 3 is located on the side of the transmission rod 2 away from the lock body 1. Specifically, the multi-point integrated lock body also includes a lock body panel 3, which is used to protect the transmission rod 2. The lock body panel 3 extends along the length of the transmission rod 2 and is located on the side of the transmission rod 2 away from the lock body 1, that is, the lock body panel 3 is located on the side of the transmission rod 2 closer to the lock seat. The lock body panel 3 is connected to the main lock body 11 and the auxiliary lock body 12. A transmission channel is formed between the lock body panel 3 and the lock body 1. The transmission rod 2 is located in the transmission channel and can slide in the transmission channel. The lock body panel 3 is fixedly connected to the main lock body 11 and the auxiliary lock body 12. The drive assembly 111 and the driven assembly 121 are both fixedly connected to the transmission rod 2. When the drive assembly 111 is working, the transmission rod 2 slides in the transmission channel under the drive of the drive assembly 111 to drive the driven assembly 121, thereby driving the latch 15 of the auxiliary lock body 12 to perform telescopic movement.
[0061] In this embodiment, the lock body panel 3 and the lock body 1 are located on both sides of the transmission rod 2. The lock body panel 3 is fixedly connected to the main lock body 11 and the auxiliary lock body 12 so that the transmission rod 2 can slide within the lock body panel 3. The lock body panel 3 protects the transmission rod 2, preventing the transmission rod 2 from directly contacting the outside world and improving the service life of the transmission rod 2.
[0062] More specifically, refer to Figure 14 As shown, the cross-sectional shape of the lock body panel 3 is "U" or "I" shaped, so that the transmission rod 2 can be better located inside the lock body panel 3, thereby improving the structural stability of the multi-point integrated lock body.
[0063] More specifically, refer to Figure 13 As shown, the lock body panel 3 is provided with several screw holes. The screw holes are used to avoid screws so that one end of the screw can pass through the screw holes to be fixedly connected to the main lock body 11 or the auxiliary lock body 12, thereby fixing the lock body panel 3 and the lock body 1. The connection method is simple and the installation and disassembly efficiency is high.
[0064] Furthermore, referring to Figure 13 As shown, the transmission rod 2 has a corresponding through hole at the position of the screw hole on the lock body panel 3. The through hole is used for the screw to pass through and be fixedly connected to the lock body 1. In this embodiment, the through hole is a strip-shaped hole.
[0065] In one embodiment, reference is made to Figure 2 and Figure 3 As shown, the transmission rod 2 is also provided with a clearance opening 25. Both ends of the main lock body 11 and the auxiliary lock body 12 include a support part 13. The support part 13 extends along the height direction of the main lock body 11 or the auxiliary lock body 12. One end of the support part 13 passes through the clearance opening 25 and is fixedly connected to the lock body panel 3. The support part 13 is also slidably connected to the transmission rod 2. Specifically, both ends of the main lock body 11 and the auxiliary lock body 12 include support portions 13. The support portions 13 are used to fix and support the lock body panel 3 to ensure that the transmission rod 2 can be located between the lock body panel 3 and the main lock body 11 and the auxiliary lock body 12, and can slide inside. The support portions 13 extend along the height direction of the main lock body 11 or the auxiliary lock body 12, and one end of the support portion 13 extends to one side of the lock body panel 3 to abut against and be fixedly connected to the lock body panel 3. The transmission rod 2 is also provided with a clearance opening 25, which passes through both sides of the transmission rod 2 and is positioned corresponding to the support portion 13. The clearance opening 25 is used to avoid the support portion 13 so that one end of the support portion 13 can pass through the clearance opening 25 and be flush with the lock body panel. Plate 3 is fixedly connected, that is, the support part 13 protrudes outward from the main lock body 11 and the auxiliary lock body 12 and passes through the transmission rod 2 and is fixed to the lock body panel 3. Therefore, a transmission channel is formed between the lock body panel 3 and the main lock body 11 and the auxiliary lock body 12. The transmission rod 2 is located below the lock body panel 3 and passes through the transmission channel to ensure the movement space of the transmission rod 2 and improve the movement stability of the transmission rod 2. At the same time, the length of the clearance opening 25 is greater than the length of the support part 13. Therefore, when the transmission rod 2 slides, the support part 13 is slidably connected to the transmission rod 2. That is, the support part 13 can slide within the clearance opening 25 to avoid affecting the running state of the transmission rod 2, ensuring that the transmission rod 2 and the support part 13 do not interfere with each other, and improving the structural stability of the multi-point connected lock body.
[0066] More specifically, refer to Figure 2As shown, the main lock body 11 also includes an additional support part 13 in the middle, that is, the main lock body 11 includes three support parts 13, which are located on the left, middle and right sides of the main lock body 11 respectively, thereby supporting and fixing the lock body panel 3 from three positions, so as to improve the fixing stability of the main lock body 11 and the lock body panel 3 and the supporting effect on the lock body panel 3.
[0067] In a specific embodiment, refer to Figure 10 and Figure 11 As shown, both the main lock body 11 and the secondary lock body 12 also include a face shell 14, which encloses a receiving space. The width of the receiving space is greater than the width of the support part 13, and the support part 13 is fixed on both sides of the receiving space. Specifically, both the main lock body 11 and the auxiliary lock body 12 also include a face shell 14. The face shell 14 is used to protect the internal structural components of the main lock body 11 or the auxiliary lock body 12. The face shell 14 encloses and forms a receiving space, which is used to install the drive assembly 111 or the driven assembly 121, as well as structural components such as the lock tongue 15 and the support part 13. This ensures that the main structural components of the main lock body 11 and the auxiliary lock body 12 are located inside the face shell 14, protecting the main structural components of the main lock body 11 and the auxiliary lock body 12 and improving their service life. At the same time, the width of the support part 13 is smaller than the width of the receiving space, and the height of the support part 13 is greater than the height of the receiving space. The support part 13 is fixed on both sides of the receiving space to ensure the formation of the transmission channel, thereby ensuring the movement of the transmission rod 2 within the transmission channel and improving the structural stability of the multi-point connected lock body.
[0068] In one embodiment, reference is made to Figure 2 and Figure 3As shown, both the main lock body 11 and the auxiliary lock body 12 also include a latch 15. The latch 15 is slidably connected to the drive assembly 111 or the driven assembly 121, and one end of the latch 15 passes through the clearance opening 25 to perform telescopic movement. Specifically, the main lock body 11 and each auxiliary lock body 12 also include a latch 15. The latch 15 is used to cooperate with the lock seat to realize the locking or unlocking function of the main lock body 11 and the auxiliary lock body 12. The latch 15 of the main lock body 11 is slidably connected to the drive assembly 111, and the latch 15 of the auxiliary lock body 12 is slidably connected to the driven assembly 121. When the drive assembly 111 or the driven assembly 121 is driven, it will synchronously drive the latch 15 of the main lock body 11 and the latch 15 of the auxiliary lock body 12 to extend or retract towards or away from the lock seat. Since the transmission rod 2 is located on one side of the main lock body 11 and the auxiliary lock body 12, in order to ensure that multiple latches 15 can enter... The transmission rod 2 can perform normal telescopic movement, while reducing the production cost of the transmission rod 2 and improving the installation efficiency of the transmission rod 2. In addition to avoiding the support part 13 so that one end of the support part 13 can be fixedly connected to the lock body panel 3, the clearance opening 25 can also be used to avoid the bolt 15, so that one end of the bolt 15 can pass through the clearance opening 25 to make telescopic movements closer to or away from the lock seat. When the drive component 111 and the driven component 121 are driven synchronously, multiple bolts 15 can pass through the clearance opening 25 synchronously to extend or retract, so as to realize the locking or unlocking function of the bolt 15 with each lock seat and improve the structural stability of the multi-point connected lock body.
[0069] In this embodiment, the support part 13 and the locking tongue 15 are simultaneously avoided by the avoidance opening 25. Therefore, the length of the avoidance opening 25 is relatively long, and it is not necessary to design two through holes to avoid the support part 13 and the locking tongue 15 respectively, thereby reducing production costs and improving production efficiency and assembly efficiency.
[0070] This embodiment also provides a lock (not shown in the figure), which includes a multi-point integrated lock body. The multi-point integrated lock body can be any type of multi-point integrated lock body provided by this utility model. Since the specific structure and working principle of the multi-point integrated lock body have been described in detail in the previous description, they will not be repeated here for the sake of brevity.
[0071] The lock in this embodiment utilizes a multi-point integrated lock body provided by this invention. This multi-point integrated lock body has a small cumulative transmission error and high transmission precision. Therefore, the high transmission precision ensures coordinated operation of all lock components, reducing jamming or failure caused by errors and improving lock security. Simultaneously, the low cumulative error keeps the lock stable during long-term use, reducing the failure rate and enhancing reliability. Furthermore, precise transmission reduces wear on lock components, extending lock life. Finally, high-precision transmission makes unlocking and locking smoother, improving user experience.
[0072] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
