Description

Technical Field

[0001] This application relates to the technical field of locks, and in particular to a two-point lock. Background Technology

[0002] In existing technologies, smart window locks can automatically close or open windows, but they cannot press the window shut when locked, resulting in poor sealing performance after the window is closed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, one of the purposes of this application is to provide a two-point lock that has the advantage of pressing the window tightly when locked, thereby improving the window sealing effect.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A two-point lock includes a locking assembly and a latch. The locking assembly includes a power component, a locking bar, and a lock head. One end of the power component is rotatably connected to the locking bar, and the other end is rotatably connected to a fixed facility. The power component is used to drive the locking bar away from or towards the fixed facility and rotate it. The locking bar is movably connected to a window. The locking bar is used to drive the lock head to extend into the latch and approach the window when rotating.

[0006] By adopting the above technical solution, the power component drives the locking rod to move, so that the window opens or closes with the movement of the locking rod. One end of the power component is rotatably connected to the locking rod, and the other end is rotatably connected to the fixing device, so that the locking rod can rotate and drive the lock head to rotate, so that the window can be closed. When the locking rod rotates, it approaches the window, so that the locking rod applies pressure to the window, thereby enabling the locking rod to press the window tightly when locked, resulting in a better window sealing effect.

[0007] In a preferred embodiment, this application may be further configured such that the lock head includes an insert end and a tail end, the insert end being at a greater distance from the center of the lock bar than the tail end being at a greater distance from the center of the lock bar, and the insert end being used to insert into the latch.

[0008] By adopting the above technical solution, since the distance from the inserted end to the center of the locking rod is greater than the distance from the end to the center of the locking rod, when the inserted end continues to rotate after being inserted into the latch, the locking rod and the window body come into contact and apply pressure to the window body.

[0009] In a preferred embodiment, the present application may be further configured such that the locking component includes a connecting rod for rotatably connecting to one end of the power component.

[0010] By adopting the above technical solution, the locking rod and one end of the power component are rotatably connected by the connecting rod.

[0011] In a preferred embodiment, this application can be further configured such that: the locking bar has a contact and a fixing member, the locking bar applies pressure to the window through the contact, and the fixing member is used to limit the position of the contact on the locking bar.

[0012] By adopting the above technical solution, the fixing component limits the position of the contact component on the locking rod, reducing the probability of rotation between the contact component and the locking rod. The contact component limits the rotation direction of the locking rod, making it less likely for the locking rod to rotate in the wrong direction. When the power component drives the locking rod to rotate, causing the lock head to enter the latch, the locking rod applies pressure to the window and window frame through the contact component, thereby improving the sealing between the two. When the power component drives the lock head to leave the latch, rotation occurs between the locking rod and the power component, and the rotation stops after reaching the appropriate position.

[0013] In a preferred embodiment, this application may be further configured such that the latch has an opening and a receiving groove, the lock head extends into the latch through the opening, and the receiving groove is used to define the position of the lock head within the latch.

[0014] In a preferred embodiment, this application may be further configured such that the latch is provided with an adjusting member for adjusting the rotation range of the lock head.

[0015] By adopting the above technical solution, the adjusting component adjusts the rotation range of the lock head, thereby adjusting the pressure applied by the lock rod to the window.

[0016] In a preferred embodiment, this application can be further configured such that the lock head has a limiting groove for engaging the latch.

[0017] By adopting the above technical solution, the limiting groove fits the latch, preventing the lock head from moving laterally within the latch.

[0018] In a preferred embodiment, this application may be further configured such that the fixed facility includes a telescopic pole for adjusting the length of the fixed facility.

[0019] By adopting the above technical solution, the length of the telescopic pole adjustment fixing facility can be adjusted so that the position of the end connected to the power component and the fixing facility can be adjusted. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 4 The present application discloses a two-point lock, which includes a locking component 1 and two sets of latches 2, with the latches 2 fixed on both sides of the window frame.

[0027] The locking assembly 1 includes a power component 3, a locking rod 4, a connecting rod 5, and a lock head 6. The lock head 6 is located at both ends of the locking rod 4. One end of the power component 3 is rotatably connected to the locking rod 4, and the other end is rotatably connected to the fixing facility 8. The power component 3 is used to drive the locking rod 4 away from or towards the fixing facility 8 and rotate it. The locking rod 4 is movably connected to the window 7. The locking rod 4 is used to drive the lock head 6 to extend into the latch 2 and approach the window 7 when rotating. The connecting rod 5 is used to limit the rotation direction of the locking rod 4. In this embodiment, the power component 3 can be a cylinder or an electric push rod.

[0028] The lock head 6 includes an insertion end 61 and a tail end 62. The distance between the insertion end 61 and the center of the lock rod 4 is greater than the distance between the tail end 62 and the center of the lock rod 4. The insertion end 61 is used to insert into the latch 2. The lock head 6 is provided with a limiting groove 63, which is used to fit the latch 2 and reduce the probability of the lock head 6 slipping laterally inside the latch 2.

[0029] The locking rod 4 is provided with a contact 41 and a fixing member 42. The locking rod 4 applies pressure to the window 7 through the contact 41, and the fixing member 42 is used to limit the position of the contact 41 on the locking rod 4. In this embodiment, the contact 41 can be a spring, and the fixing member 42 can be a screw.

[0030] The connecting rod 5 is provided with a limiting surface 51, which is used to limit the angle between the connecting rod 5 and the power component 3. The window 7 is provided with a limiting block 71, which is used to limit the position between the connecting rod 5 and the power component 3 to prevent the connecting rod 5 from rotating in the opposite direction.

[0031] The latch 2 is provided with an opening 21, a receiving groove 22 and an adjusting member 23. The lock head 6 extends into the latch 2 through the opening 21. The receiving groove 22 is used to limit the position of the lock head 6 in the lock mouth. The adjusting member 23 is used to adjust the rotation range of the lock head 6. In this embodiment, the adjusting member 23 can be a screw.

[0032] The fixed facility 8 includes a telescopic rod 81 and a fixed rod 82. The telescopic rod is used to adjust the length of the fixed facility 8. One end of the telescopic rod 81 is hinged to the power component 3 via a pin 83 and is detachably connected. The other end is threaded to the fixed rod 82. The telescopic rod 81 is provided with external threads. The fixed rod 82 is hollow and is provided with internal threads that cooperate with it. By rotating the telescopic rod 81, the position between the telescopic rod 81 and the fixed rod 82 can be adjusted, thereby adjusting the length of the fixed facility 8.

[0033] When the window 7 is closed, the power component 3 drives the locking rod 4 away from the fixing device 8 through the connecting rod 5, so that the window 7 transitions from the open state to the closed state. The fixing component 42 limits the position of the contact 41 on the locking rod 4, so that there is no rotation between the contact 41 and the locking rod 4. The limiting block 71 limits the position between the connecting rod 5 and the power component 3 to prevent the connecting rod 5 from rotating in the opposite direction, so that the locking rod 4 is hindered when it tends to rotate in the wrong direction. When the window 7 is in the closed state, the extension end 61 of the lock head 6 corresponds to the opening 21 of the latch 2. The locking rod 4 begins to rotate under the action of the power component 3. Since the distance between the extension end 61 and the center of the locking rod 4 is greater than the distance between the end end 62 and the center of the locking rod 4, the extension end 61 continues to rotate after entering the receiving groove 22, so that the locking rod 4 is closer to the window 7. As the locking rod 4 rotates counterclockwise, the contact 41 is squeezed and applies pressure to the window 7, thereby making the seal between the window 7 and the frame better.

[0034] By rotating the adjusting member, the position of the lock head 6 within the receiving groove 22 can be finely adjusted, and the rotation range of the lock head 6 can be finely adjusted, thereby allowing the pressure applied by the lock rod 4 to the window 7 through the contact member 41 to be finely adjusted.

[0035] When window 7 is opened, the power component 3 drives the locking rod 4 to rotate in the opposite direction through the connecting rod 5. The locking rod 4 drives the lock head 6 to rotate, causing the lock head 6 to exit from the outlet and leave the receiving groove 22, thereby causing window 7 to rotate. The power component 3 continues to drive the locking rod 4 to approach the fixing device 8 through the connecting rod 5, so that window 7 is opened.

[0036] The implementation principle of this embodiment is as follows: the power component 3 drives the locking rod 4 to move, so that the window 7 opens or closes with the movement of the locking rod 4. One end of the power component 3 is rotatably connected to the locking rod 4, and the other end is rotatably connected to the fixing device 8, so that the locking rod 4 can rotate and drive the lock head 6 to rotate, so that the window can be closed. When the locking rod 4 rotates, it approaches the window, so that the locking rod 4 applies pressure to the window 7, thereby enabling the locking rod 4 to press the window tightly when locked, so that the window sealing effect is better.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
