Lock transmission components, handle mechanism and lock

Abstract

This utility model discloses a lock transmission assembly, a handle mechanism, and a lock. The lock transmission assembly is used in a lock, which includes a lock housing and a lock rod. The lock housing is mounted on an upper or lower track, and the lock rod can move up and down between a locked position and an unlocked position. When the lock rod is in the locked position, it extends into the lock housing. The lock transmission assembly includes: a fixed side shell for fixing to the vertical frame of a door or window sash; and a sliding side plate slidably connected to the fixed side shell, which connects to the lock rod. A guide limit is formed between the sliding side plate and the fixed side shell to guide the sliding side plate to move relative to the fixed side shell in a first direction, which is perpendicular to the horizontal plane. Thus, by using the guide limit between the sliding side plate and the fixed side shell to guide the sliding side plate to move in a direction perpendicular to the horizontal plane, the sliding side plate adaptation problem caused by vertical frame size deviation is avoided, ensuring that the sliding side plate can stably drive the lock rod to move accurately up and down between the locked and unlocked positions.

Description

Technical Field

[0001] This utility model belongs to the technical field of door and window hardware accessories, specifically relating to lock transmission components, handle mechanisms and locks. Background Technology

[0002] Chinese Patent Publication No. CN119664183A discloses a sliding door locking structure and door mechanism. The door mechanism includes an upper track, a door body, a handle, and a sliding door locking structure. The locking structure includes a lock box, a vertical frame, and a locking rod. The lock box is located on the upper track, the handle is located on the door body, and the vertical frame is located on the vertical side wall of the door body. The locking rod and the handle are connected by a transmission mechanism. One end of the locking rod has a latch. Driven by the handle, the locking rod can move up and down to engage or disengage the latch into the lock groove of the lock box. This door mechanism positions the lock box and latch on the upper side of the door body to remove them from the user's view, thereby improving the aesthetics of the door and window system. The handle has a sliding side plate, and the locking rod is connected to the sliding side plate. The movable side plate moves up and down synchronously with the sliding side plate. In order to ensure that the sliding side plate can move in a direction perpendicular to the horizontal plane so as to drive the locking rod to move in a direction perpendicular to the horizontal plane, the sliding side plate needs to be fastened to the vertical edge of the vertical frame. The fastening connection between the sliding side plate and the vertical frame guides the sliding side plate to move in a direction perpendicular to the horizontal plane. However, since the vertical frame is made of profiles, there is a certain deviation in the size of the vertical frame during the production process. If the vertical frame is too thick, it will be difficult for the sliding side plate to fasten with the edge of the vertical frame. If the vertical frame is too thin, even if the sliding side plate is fastened to the edge of the vertical frame, the sliding side plate is prone to tilting or shaking during the movement and cannot drive the locking rod to move in a direction perpendicular to the horizontal plane.

[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0024] Example 1 Please see Figures 1 to 7 This application provides a lock transmission assembly for a lock 100. The lock 100 includes a lock box 3 and a lock rod 4. The lock box 3 is mounted on an upper track 200 or a lower track. The lock rod 4 can move up and down between a locked position and an unlocked position. When the lock rod 4 is in the locked position, the lock rod 4 extends into the lock box 3. When the lock rod 4 is in the unlocked position, the lock rod 4 is disengaged from the lock box 3.

[0025] like Figure 2 and Figure 3 As shown, the lock transmission assembly includes a fixed side shell 1 and a sliding side plate 2. The fixed side shell 1 is fixed to the vertical frame 301 of the door / window sash 300 or the handle base 6. The sliding side plate 2 is slidably connected to the fixed side shell 1 and is used to connect the lock rod 4. A guide limit is formed between the sliding side plate 2 and the fixed side shell 1 to guide the sliding side plate 2 to move relative to the fixed side shell 1 in a first direction, which is a direction perpendicular to the horizontal plane. Specifically, the first direction can be referred to as... Figure 4 In the e1 direction.

[0026] The lock transmission assembly disclosed in this application uses a guide limit between the sliding side plate 2 and the fixed side shell 1 to guide the sliding side plate 2 to move in a direction perpendicular to the horizontal plane. This avoids the fitting problem of the sliding side plate 2 caused by the size deviation of the vertical frame 301, and ensures that the sliding side plate 2 can stably drive the lock rod 4 to move accurately up and down between the locked position and the unlocked position. This allows the lock rod 4 to accurately extend into or out of the lock box 3 during the movement, effectively realizing the locking and unlocking functions of the door and window system, and improving the stability and reliability of the lock 100.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, the fixed side shell 1 includes a main body 13, a first guide block 11, and a second guide block 12, which are correspondingly disposed on the upper and lower sides of the main body 13. The sliding side plate 2 has a sliding cavity 23, a first guide groove 21, and a second guide groove 22, all extending along a first direction, which are correspondingly disposed on the upper and lower sides of the sliding cavity 23. The main body 13 and the sliding cavity 23 are slidably connected. The sliding side plate 2 can move up and down relative to the fixed side shell 1 at a first position and a second position. When the sliding side plate 2 moves to the first position, as... Figure 4 and Figure 6 As shown, the first guide block 11 and the first guide groove 21 are slidably connected; when the sliding side plate 2 moves to the second position, as... Figure 5 and Figure 7 As shown, the second guide block 12 and the second guide groove 22 are slidably connected. Thus, by providing the first guide block 11 and the second guide block 12 on the upper and lower sides of the main body 13 on the fixed side shell 1, and correspondingly providing the first guide groove 21 and the second guide groove 22 on the upper and lower sides of the sliding cavity 23 on the sliding side plate 2, at least one set of guide blocks and guide grooves is always in a sliding cooperation state regardless of the position of the sliding side plate 2 during its vertical movement relative to the fixed side shell 1. For example, when the sliding side plate 2 moves to the middle position, the first guide block 11 and the first guide groove 21, and the second guide block 12 and the second guide groove 22, function simultaneously; when the sliding side plate 2 moves close to the first position, the first guide block 11 and the first guide groove 21 closely cooperate to provide the main guidance, ensuring that the sliding side plate 2 does not experience significant displacement even if the cooperation between the second guide block 12 and the second guide groove 22 gradually weakens; similarly, when approaching the second position, the second guide block 12 and the second guide groove 22 play a dominant role. This design greatly improves the stability of the sliding side plate 2's movement, avoiding problems such as tilting and wobbling caused by the failure of a single guide structure at a specific position. The stable guide structure ensures that the sliding side plate 2 can move strictly in a first direction perpendicular to the horizontal plane, allowing the locking rod 4 connected to the sliding side plate 2 to accurately switch between the locked and unlocked positions.

[0028] In one embodiment, when the sliding side plate 2 is in the first position, it can drive the locking rod 4 to move to the unlocked position; when the sliding side plate 2 is in the second position, it can drive the locking rod 4 to move to the locked position.

[0029] In some other embodiments, when the sliding side plate 2 is in the first position, it can move the locking rod 4 to the locked position; when the sliding side plate 2 is in the second position, it can move the locking rod 4 to the unlocked position. The specific configuration can be adjusted according to actual needs.

[0030] It should be noted that in some other embodiments, the guide groove can be set on the fixed side plate and the guide block can be set on the sliding side plate 2, so that the guide groove and the guide block can slide together. This is not the only limitation.

[0031] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the sliding cavity 23 is provided with a first limiting block 231 and a second limiting block 232 distributed vertically at intervals. The edge of the first side of the main body 13 is formed with a limiting step 131 extending in a first direction. When the sliding side plate 2 moves to the first position, the first guide block 11 and the first guide groove 21 are slidably connected, the first limiting block 231 and the limiting step 131 are slidably connected, and the first limiting block 231 can limit the displacement of the limiting step 131 in the horizontal direction. When the sliding side plate 2 moves to the second position, the second guide block 12 and the second guide groove 22 are slidably connected, the second limiting block 232 and the limiting step 131 are slidably connected, and the second limiting block 232 can limit the displacement of the limiting step 131 in the horizontal direction. Thus, firstly, regardless of whether the sliding side plate 2 is in the first position, the second position, or any position in between, at least two guide limits function simultaneously. During sliding, this continuous guiding support prevents problems such as shaking and jamming caused by guide failure in the sliding side plate 2, making the movement of the sliding side plate 2 more stable and smooth. For example, in scenarios where doors and windows are frequently opened and closed, stable guiding performance ensures that the lock 100 can reliably complete the locking and unlocking actions each time, improving the overall performance and reliability of the lock 100. Secondly, when the sliding side plate 2 moves, the guide block slides in the guide groove, providing basic guidance for the sliding side plate 2 along the first direction (perpendicular to the horizontal plane), ensuring its movement trajectory is accurate. The cooperation between the limit block and the limit step 131 further finely adjusts and constrains the movement of the sliding side plate 2, effectively limiting its displacement in the horizontal direction and preventing the sliding side plate 2 from deviating in the horizontal direction. This dual effect allows the sliding side plate 2 to accurately reach the first or second position, ensuring that the locking rod 4 can accurately extend into the lock box 3 to achieve the locking function.

[0032] In one embodiment, the bottom wall and side wall of the first guide groove 21 extend along a first direction, and the bottom wall and side wall of the second guide groove 22 also extend along the first direction.

[0033] like Figure 2 and Figure 3As shown, in one embodiment, the main body 13 is provided with a first guide slope 132 and a second guide slope 133. During the process of the main body 13 being inserted into the sliding cavity 23, the first guide slope 132 slides relative to the first limiting block 231, and the second guide slope 133 slides relative to the second limiting block 232. Thus, during the process of the main body 13 being inserted into the sliding cavity 23, by pressing the main body 13, the main body 13 can be guided into the sliding cavity 23 through the first guide slope 132 and the second guide slope 133, so that the main body 13 can be smoothly inserted into the sliding cavity 23 without any obstruction. This design cleverly solves the interference problem that may occur between the main body 13 and the surrounding structure of the sliding cavity 23 during installation.

[0034] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment, the bottom wall of the first guide groove 21 is provided with a first sliding groove 211, the first side of the first guide block 11 is provided with a first slider 111, the bottom wall of the second guide groove 22 is provided with a second sliding groove 221, and the first side of the second guide block 12 is provided with a second slider 121. When the sliding side plate 2 is in the first position, the first slider 111 and the first sliding groove 211 are slidably connected, and the first side of the first guide block 11 contacts the bottom wall of the first guide groove 21 to restrict the movement of the sliding side plate 2 in the horizontal direction. When the sliding side plate 2 is in the second position, the second slider 121 and the second sliding groove 221 are slidably connected, and the first side of the second guide block 12 contacts the bottom wall of the second guide groove 22 to restrict the movement of the sliding side plate 2 in the horizontal direction. Thus, firstly, the basic guidance provided by the first guide block 11 and the first guide groove 21, and the second guide block 12 and the second guide groove 22, provides a moving path for the sliding side plate 2 along the first direction (perpendicular to the horizontal plane). Secondly, the cooperation between the first slider 111 and the first slide groove 211, and the second slider 121 and the second slide groove 221, further refines the guidance, making the movement of the sliding side plate 2 in the vertical direction more precise. For example, when the sliding side plate 2 moves to the first position, the first guide block 11 slides in the first guide groove 21, and the first slider 111 simultaneously slides in the first slide groove 211. This dual guiding effect ensures that the sliding side plate 2 can accurately reach the first position, guaranteeing that the locking rod 4 can accurately extend into the lock box 3 to achieve the locking function.

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, the first guide groove 21 has a third limiting block 212 on its sidewall, the first guide block 11 has a first step 112 extending in a first direction on its second side, the second guide groove 22 has a fourth limiting block 222 on its sidewall, and the second guide block 12 has a second step 122 extending in a first direction on its second side. When the sliding side plate 2 is in the first position, the third limiting block 212 and the first step 112 are slidably connected, and the third limiting block 212 can limit the horizontal displacement of the first step 112. When the sliding side plate 2 is in the second position, the fourth limiting block 222 and the second step 122 are slidably connected, and the fourth limiting block 222 can limit the horizontal displacement of the first step 112. With this configuration, based on the original guide structure, the cooperation between the third limiting block 212 and the first step 112, and the fourth limiting block 222 and the second step 122, forms a multi-level guide system. When the sliding side plate 2 moves, the first guide block 11 slides in the first guide groove 21 and the second guide block 12 slides in the second guide groove 22 to provide basic guidance. The sliding connection between the third limiting block 212 and the first step 112, and the fourth limiting block 222 and the second step 122, further refines and strengthens the guiding effect. For example, during the movement of the sliding side plate 2 towards the first position, the first guide block 11 slides in the first guide groove 21 to determine the movement path along the first direction. At the same time, the third limiting block 212 gradually contacts and slides with the first step 112, accurately guiding the sliding side plate 2 to move along the predetermined path, ensuring that it can accurately reach the first position, so that the locking rod 4 can accurately extend into the lock box 3 to achieve locking, greatly improving the accuracy of the operation of the lock 100. Furthermore, the connection between the third limiting block 212, the first step 112, the fourth limiting block 222, and the second step 122 provides precise positioning when the sliding side plate 2 reaches the first and second positions. These features not only limit the horizontal displacement of the sliding side plate 2 but also ensure that it accurately stops at the predetermined position in the vertical direction, avoiding problems such as insecure locking or difficulty in unlocking due to positional deviations.

[0036] like Figure 2 and Figure 3 As shown, in one embodiment, the lock transmission assembly further includes an elastic element 5, which is disposed between the main body 13 and the sliding cavity 23. The elastic element 5 is used to elastically drive the sliding side plate 2 to move to a first position or a second position, so as to ensure that the sliding side plate 2 moves into place. In this way, the elastic element 5, with its preset elasticity characteristics, can provide a stable and predictable driving force for the sliding side plate 2. During the operation of the lock transmission assembly, it can ensure that the sliding side plate 2 moves precisely to the first position or the second position strictly according to the design requirements.

[0037] like Figure 2 and Figure 3As shown, in one embodiment, a first protrusion 134 is provided on the second side of the main body 13, and a second protrusion 233 is provided in the sliding cavity 23. The elastic element 5 is a torsion spring, with its first end connected to the first protrusion 134 and its second end connected to the second protrusion 233. Thus, by placing the torsion spring between the second side of the main body 13 and the sliding cavity 23, and connecting it via the first protrusion 134 and the second protrusion 233, this design fully utilizes the limited space between the main body 13 and the sliding cavity 23. No additional external structure is needed to house the torsion spring, making the entire lock transmission assembly more compact. It achieves elastic drive function without occupying excessive space, making it suitable for various lock applications with high space requirements.

[0038] like Figure 2 and Figure 3 As shown, in one embodiment, the lock transmission assembly further includes a transmission arm 8, which is laterally disposed on the sliding side plate 2. The transmission arm 8 is used for transmission connection with the actuating block 7 of the handle mechanism. The transmission arm 8 can move along a first direction following the actuating block 7. Under the drive of the transmission arm 8, the sliding side plate 2 moves relative to the fixed side shell 1 along the first direction. Thus, when the user operates to slide the actuating block 7, the transmission arm 8 can accurately transmit the force generated by the actuating block 7 to the sliding side plate 2, ensuring that the sliding side plate 2 can be effectively driven to move.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the transmission arm 8 is provided with a transmission groove 81 for transmission connection with the toggle block 7.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, the transmission arm 8 and the sliding side plate 2 are integrally formed. Thus, on the one hand, the integral design eliminates the connection gap and additional installation space between the transmission arm 8 and the sliding side plate 2 in traditional split structures. Within the limited space inside the lock 100, this compact structure allows for a more rational layout of other components, reducing the overall size of the lock transmission assembly. On the other hand, the integrally formed transmission arm 8 and sliding side plate 2 form a continuous and complete structure, eliminating structural instability issues caused by loose or detached connecting parts. Even under frequent forces and vibrations during long-term use, the structure maintains its integrity and stability, greatly improving the reliability and durability of the lock transmission assembly.

[0041] Example 2 like Figure 1As shown, this embodiment provides a handle mechanism, including a lock transmission assembly as described in any embodiment of Example 1. The handle mechanism also includes a handle base 6 and a lever block 7. The handle base 6 is fixed to the door / window sash, the fixed side shell 1 is fixedly connected to the handle base 6, and the lever block 7 is disposed on the handle base 6. The lever block 7 is pulsatorically connected to the sliding side plate 2. Under the drive of the lever block 7, the sliding side plate 2 moves along a first direction. Thus, this handle mechanism organically integrates the lock transmission assembly, the handle base 6, and the lever block 7. The lock transmission assembly, as the core transmission part, works in conjunction with the handle base 6 and the lever block 7. The components are compactly arranged, making full use of the limited space. This integrated design makes the installation of the entire handle mechanism on the door / window sash more convenient and does not occupy too much external space, making it particularly suitable for modern building doors and windows with high space requirements.

[0042] In one embodiment, the actuating block 7 is slidably disposed on the handle seat 6 along the first direction, and the sliding side plate 2 can be driven to move up and down by directly actuating the actuating block 7.

[0043] In some other embodiments, the actuating block 7 may also be rotatably mounted on the handle seat 6. A transmission mechanism is provided between the actuating block 7 and the sliding side plate 2. By rotating the actuating block 7, the transmission mechanism can convert the rotation of the actuating block 7 into the up and down movement of the sliding side plate 2. The transmission mechanism may be, but is not limited to, a gear and rack transmission mechanism or a cam and slider transmission mechanism, whichever is selected according to actual needs.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the handle mechanism further includes a fastener 9. The fixed side shell 1 is provided with a first fastening hole 14, and the handle seat 6 is provided with a second fastening hole (not shown). The fastener 9 passes through the first fastening hole 14 and the second fastening hole. This forms a robust mechanical connection. This connection can withstand significant external forces, ensuring that the fixed side shell 1 and the handle seat 6 will not easily separate during the use of the door and window.

[0045] It should be noted that in some other embodiments, the fixed side shell 1 and the handle seat 6 may be connected by, but are not limited to, pins, rivets, or snap-fits, depending on the actual needs, and are not limited to one specific method here.

[0046] Example 3 like Figure 1 As shown. This embodiment provides a lock 100, including a handle mechanism as described in any of the above embodiments, and also includes a lock box 3 and a lock rod 4. The lock box 3 is used to be mounted on the upper track 200 or the lower track. The lock rod 4 is connected to the sliding side plate 2 in a transmission manner. Under the drive of the sliding side plate 2, the lock rod 4 moves between the unlocked position and the locked position along a first direction.

[0047] In one embodiment, the lock box 3 is provided with a lock groove, and one end of the lock rod 4 is provided with a lock tongue 41. When the lock rod 4 is in the unlocked position, the lock rod 4 causes the lock tongue 41 to separate from the lock groove; when the lock rod 4 is in the locked position, the lock rod 4 causes the lock tongue 41 to engage with the lock groove.

[0048] In one embodiment, the lock box 3 is used to be mounted on the upper track 200, such as Figure 4 and Figure 6 As shown, when the sliding side plate 2 is in the first position, it can drive the locking lever 4 to move to the unlocked position; as Figure 5 and Figure 7 As shown, when the sliding side plate 2 is in the second position, it can drive the locking rod 4 to move to the locked position.

[0049] In some other embodiments, the lock box 3 is configured on the lower track to move the locking rod 4 to the locked position when the sliding side plate 2 is in the first position; and to move the locking rod 4 to the unlocked position when the sliding side plate 2 is in the second position. The configuration can be adjusted according to actual needs.

[0050] In summary, the lock transmission assembly, handle mechanism, and lock 100 disclosed in this utility model can bring at least the following beneficial technical effects: (1) The sliding side plate 2 is guided to move in a direction perpendicular to the horizontal plane by the guide limit between the sliding side plate 2 and the fixed side shell 1, which avoids the matching problem of the sliding side plate 2 caused by the size deviation of the vertical frame 301, and ensures that the sliding side plate 2 can stably drive the locking rod 4 to move up and down accurately between the locked position and the unlocked position. (2) Regardless of whether the sliding side plate 2 is in the first position, the second position or any position in between, at least two guide limits will function simultaneously. During the sliding process, this continuous guide support avoids problems such as shaking and jamming caused by guide failure of the sliding side plate 2, making the movement of the sliding side plate 2 more stable and smooth. (3) When the sliding side plate 2 moves, the guide block slides in the guide groove, providing basic guidance for the sliding side plate 2 in the first direction and ensuring its accurate movement trajectory; while the cooperation between the limiting block and the limiting step 131 further finely adjusts and constrains the movement of the sliding side plate 2, effectively limiting its displacement in the horizontal direction and preventing the sliding side plate 2 from deviating in the horizontal direction. The dual effect enables the sliding side plate 2 to accurately reach the first position or the second position. (4) The handle mechanism organically integrates the lock transmission assembly, handle base 6, and actuating block 7. The lock transmission assembly, as the core transmission part, works in conjunction with the handle base 6 and actuating block 7. The layout of each component is compact, making full use of the limited space. This integrated design makes the installation of the entire handle mechanism on door and window sashes more convenient and does not occupy too much external space.

[0051] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
