Description

Technical Field

[0001] The invention relates to the field of door and window control hardware, and in particular to a multi-point connected lock body and a lock. Background Art

[0002] With the development of society, people's awareness of security protection in homes, businesses and other places has been continuously enhanced. The traditional single-point lock body has insufficient anti-theft performance in the face of increasingly diverse theft methods. The multi-point connected lock body can greatly increase the difficulty of prying the door by setting multiple locking points at different positions of the door, effectively improve the security protection level, and meet people's demand for high-security locks.

[0003] At present, a multi-point connected lock body is generally composed of a main lock body, a secondary lock body, a panel, and a transmission rod. The main lock body is rotated manually or automatically, and the motion structure inside the main lock body converts the rotational motion into linear motion, which is then transmitted to the secondary lock bodies at both ends by the transmission rod, thereby controlling the extension and retraction of the secondary lock bodies and realizing the control of the entire multi-point connected lock body. However, due to structural limitations, the transmission rods of current multi-point connected lock bodies are often disconnected at both ends of the main lock body and the ends of the secondary lock body, that is, the secondary lock bodies at both ends need to be connected to a transmission rod respectively. If it is necessary to add more locking points at the outer end of the secondary lock body, it is necessary to add another transmission rod. The added locking points need to be indirectly connected to the main lock body through the secondary lock body, but there must be gaps between the connection points, which leads to larger transmission errors. The connection gaps will be accumulated, and the more locking points are connected, the greater the accumulated error will be. Summary of the invention

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present invention is described in detail.

[0039] Reference Figures 1 to 14 As shown, it shows an embodiment of the multi-point connected lock body of the present invention. The multi-point connected 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 auxiliary lock body 12. The main lock body 11 includes a driving assembly 111, and the auxiliary 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 auxiliary lock body 12, and the transmission rod 2 is connected to the main lock body 11 and extends toward each auxiliary lock body 12. The transmission rod 2 is connected to the driving assembly 111 and the driven assembly 121. The transmission driving assembly 111 drives the transmission rod 2, and then drives the driven assembly 121.

[0040] Specifically, the multi-point integrated lock body is a special lock structure, which is connected to the door frame through multiple locking points. When the user opens or locks the door, only one operation (such as turning a key or handle) is required to control multiple locking points at the same time. It is easy to operate and improves the safety and stability of the lock on the door.

[0041] The multi-point connected lock body includes a lock body 1 and a transmission rod 2. The lock body 1 is used to lock or open a door. The lock body 1 includes a main lock body 11 and at least one auxiliary lock body 12. The main lock body 11 is the core part of the multi-point connected lock body. The user's main operations are applied to the main lock body 11. The main lock body 11 includes a driving component 111. The driving component 111 is used to provide the lock tongue 15 of the main lock body 11 with power to extend or retract; the auxiliary lock body 12 cooperates with the main lock body 11 to achieve locking or opening of the door. The number of auxiliary lock bodies 12 can be configured according to actual needs, but the multi-point connected lock body includes at least one auxiliary lock body 12, and each auxiliary lock body 12 includes a driven component 121. The driven component 121 is used to provide the lock tongue 15 of the auxiliary lock body 12 with power to extend or retract, and the driven component 121 is connected to the driving component 111 of the main lock body 11 through the transmission rod 2, thereby realizing the synchronous action of the main lock body 11 and the auxiliary lock body 12.

[0042] The transmission rod 2 is used to transmit power to achieve the synchronous extension or retraction of the lock tongue 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 in the direction of each auxiliary lock body 12, that is, the length of the transmission rod 2 corresponds to the position 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 driving component 111 of the main lock body 11, and the transmission rod 2 is also connected to the driven component 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, thereby achieving the synchronous action of the main lock body 11 and all the auxiliary lock bodies 12.

[0043] When the user locks or unlocks the main lock body 11, the driving component 111 starts to work, and the driving component 111 generates a main driving force. On the one hand, the main driving force will be transmitted to the lock tongue 15 of the main lock body 11, thereby controlling the lock tongue 15 to extend or retract, so as to achieve the locking or unlocking of the main lock body 11; on the other hand, the main driving force will be transmitted to the transmission rod 2, thereby driving the transmission rod 2 to move, and further, the transmission rod 2 will drive the driven components 121 of all the auxiliary lock bodies 12 to move, so that the driven components 121 generate a secondary driving force, and the secondary driving force is transmitted to the lock tongue 15 of the auxiliary lock body 12, thereby controlling the lock tongue 15 to extend or retract, so as to achieve the locking or unlocking of each auxiliary lock body 12; finally, the locking or unlocking action of the main lock body 11 and all the auxiliary lock bodies 12 is achieved synchronously.

[0044] More specifically, refer to Figure 4 As shown, the transmission rod 2 is an integrated 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 being able to penetrate the main lock body 11 and extend into each secondary lock body 12 to be connected to each secondary lock body 12, the transmission rod 2 can also penetrate the main lock body 11 and extend to each secondary lock body 12, and penetrate each secondary lock body 12, thereby connecting with other forms of locking points outside the secondary lock body 12, so as to improve the practicality of the transmission rod 2.

[0046] The present application connects the transmission rod 2 to the main lock body 11 and extends it toward the location of each auxiliary lock body 12, and the transmission rod 2 is connected to the driving component 111 and each driven component 121, so that one transmission rod 2 can connect the main lock body 11 and each auxiliary lock body 12, so that each auxiliary lock body 12 is directly connected to the main lock body 11 through the same transmission rod 2, so as to reduce the accumulated transmission error of all locking points, thereby improving the transmission accuracy of the multi-point connected lock body.

Specifically, the multi-point connected lock body also includes a lock body panel 3, which is used to protect the transmission rod 2. The lock body panel 3 is extended along the length direction of the transmission rod 2, and the lock body panel 3 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 close to the lock seat, and 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, and 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, and the driving component 111 and the driven component 121 are both fixedly connected to the transmission rod 2. When the driving component 111 is working, the transmission rod 2 slides in the transmission channel under the drive of the driving component 111 to drive the driven component 121, thereby driving the lock tongue 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 respectively 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 is inside the lock body panel 3 and can slide inside the lock body panel 3. The lock body panel 3 protects the transmission rod 2, prevents the transmission rod 2 from directly contacting the outside world, and improves the service life of the transmission rod 2.

[0062] More specifically, refer to Fig.14 As shown, the cross-sectional shape of the lock panel 3 is "U"-shaped or "I"-shaped, so that the transmission rod 2 can be better located in the lock panel 3, thereby improving the structural stability of the multi-point connected lock body.

[0063] More specifically, refer to Fig.13 As shown, a plurality of screw holes are provided on the lock body panel 3, and the screw holes are used to avoid screws so that one end of the screw can pass through the screw hole to be fixedly connected with 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, refer to Fig.13 As shown, the transmission rod 2 is provided with corresponding through holes at positions corresponding to the screw holes of the lock body panel 3, and the through holes are used for screws to pass through to be fixedly connected with the lock body 1. Meanwhile, in this embodiment, the through holes are bar-shaped holes.

[0065] In one embodiment, referring to Figure 2 and Figure 3 As shown, the transmission rod 2 is also provided with an avoidance opening 25, and both ends of the main lock body 11 and the auxiliary lock body 12 include a support portion 13, and the support portion 13 is extended along the height direction of the main lock body 11 or the auxiliary lock body 12. One end of the support portion 13 passes through the avoidance opening 25 and is fixedly connected to the lock body panel 3, and the support portion 13 is slidably connected to the transmission rod 2. Specifically, both ends of the main lock body 11 and the auxiliary lock body 12 include a support portion 13, and the support portion 13 is 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 portion 13 is extended 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 and be fixedly connected with the lock body panel 3; the transmission rod 2 is also provided with an avoidance opening 25, the avoidance opening 25 passes through both sides of the transmission rod 2, and the avoidance opening 25 is arranged corresponding to the position of the support portion 13, and the avoidance opening 25 is used to avoid the support portion 13, so that one end of the support portion 13 can pass through the avoidance opening 25 and the lock body surface The plate 3 is fixedly connected, that is, the support part 13 protrudes 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 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 avoidance 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 in the avoidance opening 25 to avoid affecting the running state of the transmission rod 2, ensure that the transmission rod 2 and the support part 13 do not interfere with each other, and improve the structural stability of the multi-point connected lock body.

[0066] More specifically, refer to Figure 2As shown, the middle part of the main lock body 11 also includes one more support part 13, that is, the main lock body 11 includes three support parts 13, and the three support parts 13 are respectively located on the left side, the middle part and the right side of the main lock body 11, so as to support and fix the lock body panel 3 from three positions 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 Fig.10 and Fig.11 As shown, the main lock body 11 and the auxiliary lock body 12 also include a surface shell 14, which encloses a receiving space. The width of the receiving space is greater than the width of the support portion 13, and the support portion 13 is fixed on both sides of the receiving space. Specifically, the main lock body 11 and the auxiliary lock body 12 also include a face shell 14, which is used to protect the internal structural parts of the main lock body 11 or the auxiliary lock body 12. The face shell 14 encloses a accommodating space, and the accommodating space is used to install the driving component 111 or the driven component 121 and install the lock tongue 15, the support part 13 and other structural parts, so that the main structural parts of the main lock body 11 and the auxiliary lock body 12 are all located inside the face shell 14, and the main structural parts of the main lock body 11 and the auxiliary lock body 12 are protected to improve the service life; at the same time, the width of the support part 13 is smaller than the width of the accommodating space, and the height of the support part 13 is greater than the height of the accommodating space. The support part 13 is fixed on both sides of the accommodating space to ensure the formation of the transmission channel, thereby ensuring the movement of the transmission rod 2 in the transmission channel and improving the structural stability of the multi-point connected lock body.

[0068] In one embodiment, referring to Figure 2 and Figure 3As shown, the main lock body 11 and the auxiliary lock body 12 also include a lock tongue 15, which is slidably connected to the driving component 111 or the driven component 121, and one end of the lock tongue 15 passes through the avoidance opening 25 to perform telescopic movement. Specifically, the main lock body 11 and each auxiliary lock body 12 also include a lock tongue 15, which is used to cooperate with the lock seat to achieve the locking or unlocking function of the main lock body 11 and the auxiliary lock body 12. The lock tongue 15 of the main lock body 11 is slidably connected to the driving component 111, and the lock tongue 15 of the auxiliary lock body 12 is slidably connected to the driven component 121. When the driving component 111 or the driven component 121 is driven, it will synchronously drive the lock tongue 15 of the main lock body 11 and the lock tongue 15 of the auxiliary lock body 12 to perform an extension or retraction movement close to 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 lock tongues 15 can be moved In order to perform normal telescopic movement, the production cost of the transmission rod 2 is reduced and the installation efficiency of the transmission rod 2 is improved. In addition to being used to avoid the support portion 13 so that one end of the support portion 13 is fixedly connected to the lock body panel 3, the avoidance opening 25 can also be used to avoid the lock tongue 15, so that one end of the lock tongue 15 can pass through the avoidance opening 25 to perform telescopic movement close to or away from the lock seat; when the driving component 111 and the driven component 121 are synchronously driven, multiple lock tongues 15 can synchronously pass through the avoidance opening 25 to extend or retract, so as to realize the locking or unlocking function of the lock tongue 15 and each lock seat, thereby improving the structural stability of the multi-point connected lock body.

[0069] In this embodiment, the avoidance opening 25 is used to avoid the support portion 13 and the lock tongue 15 at the same time, so the avoidance opening 25 is longer, and there is no need to design two through holes to avoid the support portion 13 and the lock tongue 15 respectively, thereby reducing production costs and improving production efficiency and assembly efficiency.

[0070] The present embodiment also provides a lock (not shown in the figure), which includes a multi-point connected lock body. The multi-point connected lock body can adopt any multi-point connected lock body provided by the present invention. Since the specific structure and working principle of the multi-point connected lock body have been introduced in detail in the previous description, they will not be repeated here for the sake of brevity of the description.

[0071] The lock in this embodiment adopts the multi-point connected lock body provided by the present invention. The cumulative transmission error of the multi-point connected lock body is small and the transmission accuracy is high. Therefore, the high transmission accuracy ensures the coordinated operation of the various components of the lock, reduces jamming or failure caused by errors, and improves the safety of the lock; at the same time, the low cumulative error enables the lock to remain stable during long-term use, reduces the failure rate, and enhances the reliability of the lock; and, precise transmission reduces the wear of the lock components and extends the life of the lock; finally, high-precision transmission makes unlocking and locking smoother, improving the user experience.
