[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0026] The embodiments provided by the utility model are as follows: Figures 1 to 4 As shown, a sliding window lock comprises a window lock body 100, a through hole 110 is formed on the window lock body 100, a lock core 120 is rotatably disposed in the through hole 110, one side of the bottom of the window lock body 100 is rotatably disposed on the mounting frame of the window, and the other side can be snapped onto the locked frame of the window, and a placement groove 160 is formed on the bottom of the window lock body 100;
[0027] A lock tongue 200 is slidably disposed in the placement groove 160, a portion of the lock tongue 200 passes through the side wall of the placement groove 160 and can abut against the installation frame, a limiting member 210 is fixedly disposed on the top of the lock tongue 200, and when the limiting member 210 abuts against the lock core 120, the lock core 120 blocks the limiting member 210 from sliding inwards;
[0028] A limit strip 220 is fixedly arranged at the bottom of the lock tongue 200, and a bow-shaped spring piece 230 is arranged in the placement groove 160. Both ends of the bow-shaped spring piece 230 are fixedly arranged in the placement groove 160, and the midpoint position abuts against the limit strip 220. The lock tongue 200 can drive the limit strip 220 to compress the bow-shaped spring piece 230 inward.
[0029] When using the window lock, the user rotates the window lock body 100, and the window lock body 100 rotates around the installation frame. When the window lock body 100 and the locked frame are engaged, the user stops rotating the window lock body 100, and the lock tongue 200 abuts against the installation frame. The user rotates the lock core 120 with a key, and the lock core 120 rotates to abut against the limit member 210. At this time, the window lock is in a locked state. Since the lock tongue 200 abuts against the installation frame, the user cannot rotate the window lock body 100, and cannot separate the window lock body 100 and the locked frame.
[0030] The user rotates the lock core 120 with the key, and the lock core 120 and the limit piece 210 are separated. The user rotates the window lock body 100. Since the lock tongue 200 is in contact with the installation frame, the lock tongue 200 is subjected to the reverse force of the installation frame and shrinks into the window lock body 100. The bow-shaped spring piece 230 is deformed due to the pressure of the limit strip 220, and the window lock body 100 is separated from the locked frame. At this time, the window lock is in an unlocked state, and the user can push and pull the window sash freely. Then the user releases the window lock body 100, and the bow-shaped spring piece 230 is reset, driving the lock tongue 200 to automatically reset.
[0031] Preferably, the locking tongue 200 includes a sliding portion 201 and a protruding portion 202, the sliding portion 201 and the protruding portion 202 are fixedly connected, the sliding portion 201 is slidably disposed on the placement groove 160, the protruding portion 202 passes through the side wall of the placement groove 160 and abuts against the mounting frame, and the limiting member 210 and the limiting strip 220 are fixedly disposed on the sliding portion 201.
[0032] Preferably, a clamping member 140 is fixedly provided on one side of the bottom of the window lock body 100, and a rotating shaft 150 is fixedly provided on the other side. The clamping member 140 can be clamped on the locked frame, and the rotating shaft 150 can be rotatably provided on the installation frame.
[0033] Preferably, the lock core 120 includes a lock core 130 and a lock rod 190. The lock core 130 is rotatably disposed in the through hole 110. The lock rod 190 is fixedly disposed at the bottom of the lock core 130. The position of the lock rod 190 deviates from the bottom center of the lock core 130. When the limit member 210 and the lock rod 190 are in contact, the lock rod 190 prevents the limit member 210 from sliding inward.
[0034] Preferably, both ends of the bow-shaped spring piece 230 are respectively fixedly connected with plug pins 240 , and the plug pins 240 are inserted into the side walls of the placement groove 160 . The installation and replacement of the bow-shaped spring piece 230 are facilitated by providing the plug pins 240 .
[0035] Preferably, a handle 170 is fixedly provided on the top of the window lock body 100, and the user can open and close the window by pushing and pulling the handle 170, which is convenient to operate.
[0036] Preferably, the side surface where the limit member 210 and the lock core 120 abut is an arc-shaped surface. This design increases the contact surface between the limit member 210 and the lock core 120 when they abut, making the contact between the two more stable and smooth, thereby avoiding the problem of damage and deformation of the limit member 210 and the lock core 120 after repeated use of the window lock.
[0037] Preferably, blocking blocks 250 are fixedly provided on both sides of the sliding portion 201, and the blocking blocks 250 can abut against the side walls of the placement groove 160. The blocking blocks 250 are used to prevent the sliding portion 201 from sliding out of the placement groove 160. An arc-shaped blocking strip 270 is fixedly provided on the blocking block 250, and the arc-shaped blocking strip 270 abuts against the other side wall of the placement groove 160. The blocking blocks 250 can prevent the locking tongue 200 from rebounding beyond the original position when resetting, and the arc-shaped blocking strip 270 can prevent the locking tongue 200 from being completely retracted into the placement groove 160 and unable to be reset.
[0038] Preferably, a limit block 260 is fixedly provided on the sliding portion 201 , and the limit block 260 is arranged behind the midpoint of the bow-shaped spring piece 230 . The limit block 260 is used to prevent the bow-shaped spring piece 230 from excessively rebounding, thereby increasing the service life of the bow-shaped spring piece 230 .
[0039] Preferably, a tensioning member 180 is fixedly provided on the rotating shaft 150, and the rotating shaft 150 and the tensioning member 180 are rotatably provided in the fixing hole of the mounting frame, and the tensioning member 180 abuts against the hole wall of the fixing hole. After the window lock is installed in the mounting frame, the tensioning member 180 provides a tensioning force in the fixing hole, so that the window lock is firmly fixed on the mounting frame and will not easily deviate up and down during operation.
[0040] The working principle of this embodiment, more specifically the process is as follows:
[0041] When installing the window lock, the operator installs the rotating shaft 150 on the installation frame, and the rotating shaft 150 can be flexibly rotated on the installation frame without falling off.
[0042] When using the window lock, the user rotates the window lock body 100, and the window lock body 100 rotates around the rotating shaft 150. When the inner side of the clamping piece 140 is clamped with the locked frame, the user stops rotating the window lock body 100, and the lock tongue 200 abuts against the mounting frame. The user rotates the lock core 130 with the key. Since the locking rod 190 is eccentrically arranged on the lock core 130, the locking rod 190 rotates to abut against the limit piece 210. At this time, the window lock is in a locked state. Since the lock tongue 200 abuts against the mounting frame, the user cannot rotate the window lock body 100 and cannot disengage the clamping piece 140 from the locked frame.
[0043] The user rotates the lock core 130 with the key. Since the lock rod 190 is eccentrically arranged on the lock core 130, the lock rod 190 and the limit piece 210 are disengaged. The user rotates the window lock body 100. Since the lock tongue 200 abuts against the installation frame, the lock tongue 200 contracts into the window lock body 100 due to the reverse force of the installation frame. The bow-shaped spring piece 230 is deformed due to the pressure of the limit strip 220, and the clamping piece 140 is disengaged from the locked frame. At this time, the window lock is in an unlocked state, and the user can push and pull the window sash freely. Then the user releases the window lock body 100, the bow-shaped spring piece 230 is reset, and the lock tongue 200 is automatically reset.
[0044] The sliding window lock of the utility model has a limit strip 220 fixedly arranged at the bottom of the lock tongue 200, a bow-shaped spring piece 230 is arranged in the placement groove 160, both ends of the bow-shaped spring piece 230 are fixedly arranged in the placement groove 160, and the midpoint position abuts against the limit strip 220. The lock tongue 200 can drive the limit strip 220 to compress the bow-shaped spring piece 230 inward, thereby solving the problem of the lock tongue 200 of the window lock causing the reset rebound deviation due to uneven force, thereby improving the service life of the window lock.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
