DETAILED DESCRIPTION
[0024] 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.
[0025] The embodiments provided by the utility model are as follows: Figures 1-2 As shown, a double-lift window lock comprises a window lock base 100, a window lock body 200 and a lock buckle 300, a mounting platform 120 is fixedly arranged on the window lock base 100, the window lock body 200 is rotatably arranged on the mounting platform 120, and limit blocks 130 are fixedly arranged on both sides of the window lock base 100, the limit blocks 130 are arranged on the outer side of the mounting platform 120, and a locking block 140 is fixedly arranged on the window lock base 100, and the limit blocks 130 and the locking block 140 are fixedly arranged. 40 are arranged just below the window lock body 200, a sliding lock piece 210 with a raised edge is fixedly arranged on the window lock body 200, the sliding lock piece 210 can slide on the lock buckle 300, the position of the lock buckle 300 is fixed, a lock hole 220 is opened on the window lock body 200, a lock core 230 is rotatably arranged in the lock hole 220, a lock rod 240 is fixedly arranged below the lock core 230, and the position of the lock rod 240 deviates from the bottom center of the lock core 230;
[0026] The window lock body 200 has a locked state and an unlocked state:
[0027] When the window lock body 200 is in a locked state, the locking rod 240 and the locking block 140 are in contact with each other;
[0028] When the window lock body 200 is in an unlocked state, the lock rod 240 slides around the side wall of the mounting platform 120 with the two limit blocks 130 as starting and ending points.
[0029] When the window lock needs to be unlocked, the user rotates the lock core 230 with the key. Since the lock rod 240 is eccentrically arranged on the lock core 230, the lock rod 240 rotates to the point where it contacts the side wall of the mounting platform 120, and then rotates the window lock body 200. The lock rod 240 slides around the side wall of the mounting platform 120 with the two limit blocks 130 as the starting and ending points. The user drives the sliding lock piece 210 to slide out of the lock buckle 300 by rotating the window lock body 200, and then the window frame can be lifted. At this time, the window lock body 200 is in an unlocked state.
[0030] When the window lock needs to be closed, the user rotates the window lock body 200 to make the sliding lock plate 210 slide into the lock buckle 300, and then rotates the lock core 230 with the key. Since the locking rod 240 is eccentrically arranged on the lock core 230, the locking rod 240 rotates to abut against the locking block 140. At this time, the window lock body 200 is in a locked state. If the window frame is pulled, the raised part of the sliding lock plate 210 abuts against the lock buckle 300, and the window frame cannot be pulled further.
[0031] Preferably, a mounting block 250 is fixedly provided below the window lock body 200, a through hole 150 is opened on the mounting platform 120, the mounting block 250 is arranged in the through hole 150, and a screw 400 is abutted at the bottom of the window lock base 100. The screw 400 passes through the through hole 150 and is screwed into the mounting block 250. The screw 400 is used to fix the position of the window lock body 200, which facilitates the disassembly and replacement of the window lock body 200 and makes the installation more convenient.
[0032] Preferably, a base washer 160 is fixedly disposed in the through hole 150, and the screw 400 is in contact with the window lock base 100 through the base washer 160. The base washer 160 is disposed between the window lock base 100 and the screw 400, so that the friction force on the screw 400 is smaller when rotating, which facilitates rotation and reduces the wear on the surface of the window lock base 100 and the screw 400.
[0033] Preferably, a base washer 160 is fixedly disposed in the through hole 150 , and the screw 400 and the base washer 160 are in conflict with each other.
[0034] Preferably, a gasket 170 is fixedly provided on the mounting platform 120, and the mounting block 250 passes through the gasket 170 and enters the through hole 150. The window lock body 200 contacts the mounting platform 120 through the gasket 170. The gasket 170 is arranged between the window lock body 200 and the mounting platform 120, so that the friction force on the window lock body 200 is smaller when rotating, which facilitates the rotation and reduces the wear on the surface of the window lock body 200 and the mounting platform 120.
[0035] Preferably, a first mounting hole 110 is provided on the window lock base 100 , and the provision of the first mounting hole 110 facilitates the fixed installation of the window lock base 100 .
[0036] Preferably, the lock buckle 300 includes a second mounting hole 301, a slide groove 302 and a limit piece 303. The second mounting hole 301 is opened on the side of the window lock base 100. The sliding lock plate 210 slides in the slide groove 302. The limit piece 303 is fixedly arranged at the outer wall edge of the slide groove 302, and its direction is opposite to the bottom of the slide groove 302.
[0037] Preferably, two groups of first mounting holes 110 are provided on the window lock base 100 , and the two groups of first mounting holes 110 are respectively provided at the upper and lower ends of the window lock base 100 . This design makes the window lock base 100 more securely fixed.
[0038] Preferably, the abutment between the locking block 140 and the locking rod 240 is an arc-shaped structure. This design increases the contact surface between the locking block 140 and the locking rod 240 when they abut, making the contact between the two more stable and smooth, thereby avoiding the problem of damage and deformation of the locking block 140 and the locking rod 240 after repeated use of the window lock.
[0039] Preferably, the sliding lock piece 210 is a semicircular structure. This design prevents the sliding lock piece 210 from contacting the sliding groove 302 when sliding, making the rotation of the window lock body 200 more convenient.
[0040] The double-lift window lock of the present invention is achieved by rotatably setting the window lock body 200 on the mounting platform 120, and fixing limit blocks 130 on both sides of the window lock base 100, the limit blocks 130 are arranged on the outer side of the mounting platform 120, and the locking blocks 140 are fixedly arranged on the window lock base 100, and the limit blocks 130 and the locking blocks 140 are both arranged directly below the window lock body 200, thereby realizing a hidden design of the limit blocks 130 and the locking blocks 140. The limit blocks 130 and the locking blocks 140 cannot be seen in the locked state or the unlocked state, thereby reducing the exposure of the limit blocks 130 and the locking blocks 140 to the outside, avoiding the possibility of foreign objects entering the window lock and affecting the activity of the window lock, and prolonging the service life of the window lock. In addition, the window lock has a simple structure, few parts and low cost.
[0041] 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.
