[0021] Reference Figures 1 to 3 A silent bar lock has X, Y and Z directions, which are orthogonally arranged.

[0022] The silent bar lock includes: a lock body 100, a toggle bar 200, and a lock hook structure 300.

[0023] The top wall of the lock body 100 has an operating hole 110, which is a rounded rectangular hole structure. The lock body 100 has two locking protrusions (not shown in the figure), which are symmetrically arranged and located on two side walls of the lock body 100 in the Y direction.

[0024] The toggle bar 200 is installed inside the lock body 100 and is slidably connected to the lock body 100. The toggle bar 200 can slide relative to the lock body 100 in the X direction. The toggle bar 200 is provided with a toggle structure, which is positioned corresponding to the operation hole 110.

[0025] Specifically, in this embodiment, the actuating structure is configured as an actuating groove 210. In other embodiments, the actuating structure may also be configured as a protruding structure. Those skilled in the art can select the specific construction of the actuating structure according to actual needs.

[0026] Specifically, the actuating groove 210 has actuating surfaces 220 at both ends in the X direction. These actuating surfaces 220 contact the user's finger to push the actuating structure along the X direction. Specifically, in this embodiment, the actuating surface 220 is an arc-shaped surface. This arc shape allows the actuating surface 220 to better conform to the structure of the finger, resulting in a more comfortable operating experience for the user. In other embodiments, the actuating surface 220 can also be an inclined surface. Those skilled in the art can select the specific structure of the actuating surface 220 according to actual needs.

[0027] Multiple rolling structures 230 are rotatably installed on the bottom wall and two side walls of the toggle bar 200. The rolling structures 230 are used to abut against the inner wall surface of the lock body 100, thereby reducing the contact area between the toggle bar 200 and the lock body 100, so as to reduce the noise generated by friction when the two move relative to each other, thereby reducing noise and effectively improving the quietness of this silent bar lock.

[0028] Specifically, in this embodiment, the outer periphery of the rolling structure 230 is covered with a rubber layer. By providing the rubber layer, the noise generated when the rolling structure 230 contacts the lock body 100 can be reduced.

[0029] Specifically, in this embodiment, three rolling structures 230 are rotatably mounted on the bottom wall of the actuating bar 200, and the three rolling structures 230 are arranged at equal intervals. Two rolling structures 230 are rotatably mounted on the side wall of the actuating bar 200. Since the user applies a force towards the bottom wall of the lock body 100 when operating the actuating bar 200, the three rolling structures 230 on the bottom wall of the actuating bar 200 provide support for the middle part of the actuating bar 200, thereby preventing large deformation in the middle part of the actuating bar 200 and ensuring the service life of the silent lock. Specifically, in this embodiment, the rolling structure 230 is set as a roller. In other embodiments, the rolling structure 230 can also be set as a ball bearing or other structures. Those skilled in the art can select the specific construction of the rolling structure 230 according to actual needs.

[0030] Specifically, in this embodiment, the top wall of the toggle bar 200 is provided with a contact protrusion 240, which is made of rubber. In other embodiments, the contact protrusion 240 can also be made of plastic. Those skilled in the art can select the specific material of the contact protrusion 240 according to actual needs. The contact protrusion 240 always abuts against the top wall of the lock body 100. The contact protrusion 240 can reduce the entry of external dust into the interior of the silent lock, so as to avoid the increased friction when the toggle bar 200 and the lock body 100 slide relative to each other due to the entry of external dust into the silent lock.

[0031] The end of the toggle bar 200 is provided with a locking hook 250. The locking hook 250 is elastic, and there are two locking hooks 250, each corresponding to one of two locking protrusions. The locking hooks 250 are used to engage with the locking protrusions. When the toggle bar 200 moves to the designated position, the locking hooks 250 engage with the locking protrusions to limit the toggle bar 200. When it is necessary to move the toggle bar 200 again, the user touches the toggle surface 220 away from the locking hook 250 with their finger, and then pushes the toggle surface 220 away from the locking hook 250, so that the toggle bar 200 moves away from the locking protrusions, and the toggle bar 200 can move again. The locking hook structure 300 includes: a locking hook seat 310, a locking hook body 320, and a threaded adjustment component 330.

[0032] The locking hook seat 310 has a locking groove that extends along the Y direction. The actuating bar 200 has a protruding locking bar that extends along the Y direction. The locking bar and the locking groove are positioned to correspond to each other and engage with each other, thereby enabling the locking hook seat 310 to move along the X direction with the actuating bar 200.

[0033] The locking hook seat 310 has a first connecting sliding groove 311, which extends along the Y direction and has a T-shaped groove structure.

[0034] The locking hook seat 310 has a rotating connecting groove 313, which is connected to the first connecting sliding groove 311.

[0035] The locking hook body 320 has a T-shaped structure so that the locking hook body 320 matches the shape of the first connecting sliding groove 311. The locking hook body 320 passes through the first connecting sliding groove 311 and is slidably connected to the first connecting sliding groove 311, so that the locking hook body 320 can slide relative to the locking hook seat 310 in the Y direction.

[0036] The locking hook body 320 has a threaded connection groove 321, and the inner wall of the threaded connection groove 321 has a threaded structure.

[0037] The threaded adjusting component 330 has a rotation axis parallel to the Y direction. A rotating connecting portion 331 is located in the middle of the threaded adjusting component 330, and threaded connecting portions 332 are located at both ends. The diameter of the rotating connecting portion 331 is larger than the diameter of the threaded connecting portion 332. The rotating connecting portion 331 is disposed within a rotating connecting groove 313, and the rotating connecting portion 331 is rotatably connected to the rotating connecting groove 313. The two ends of the rotating connecting groove 313 in the Y direction limit the rotation connecting portion 331 to prevent the threaded adjusting component 330 from sliding relative to the lock hook seat 310 in the Y direction. A wrench groove is provided at the end of the adjusting threaded component. The wrench groove is used to connect with a tool so that the tool can drive the adjusting threaded component to rotate around an axis parallel to the Y direction, thereby causing the lock hook body 320 to slide relative to the lock hook seat 310 in the Y direction to adjust the position of the lock hook body 320 to meet the needs of different doors and windows.

[0038] Specifically, in this embodiment, the lock body 100 has a status indicator hole 130, and the lock hook seat 310 has two status indicators 312 fixed thereon. The two status indicators 312 are arranged along the X direction, and either status indicator 312 is set to correspond to the status indicator hole 130. When the toggle bar 200 and the lock hook structure 300 move along the X direction, the position of the status indicator 312 changes, thereby switching the status indicator 312 corresponding to the status indicator hole 130 to indicate the locking state of the bar lock.
