[0025] See also Figure 1-4 The utility model provides a technical solution: a screen window lock hook, comprising:
[0026] A frame 1, and a screen window body 2 installed in the frame 1;
[0027] A buckle slot 4 is provided on one side of the screen window body 2 through a mounting mechanism 3;
[0028] A lock mechanism 5 for use with the buckle groove 4 is embedded in one side of the inner wall of the frame 1;
[0029] The mounting mechanism 3 includes a groove body 31 provided in the frame 1 of the screen body 2, a locking block 32 is slidably installed inside the groove body 31, a buckle groove 4 is provided on one side of the locking block 32, two push rods 33 are slidably installed inside the locking block 32, one end of the two push rods 33 are fixedly installed with a limiting seat 34, a cover body 35 is installed on one side of the groove body 31, a connecting groove 36 for the limiting seat 34 to pass through is provided inside the cover body 35, and a strip groove 37 for fixing the limiting seat 34 is provided inside the connecting groove 36, and an elastic member 30 is installed inside the locking block 32.
[0030] The elastic member 30 includes a circular groove 301, a resisting spring 302 and a disc 303. The surface of the locking block 32 is provided with a circular groove 301, and a disc 303 is slidably mounted inside the circular groove 301. The resisting spring 302 is clamped between one side of the disc 303 and the inner wall of the circular groove 301. The surface of the disc 303 is fixedly mounted on one end of the push rod 33. The inside of the resisting spring 302 is movably sleeved on the surface of the push rod 33. A paddle portion is provided on one side of the disc 303.
[0031] In this embodiment, the locking block 32 is placed in the groove body 31, and the cover plate is placed on one side of the screen body 2, and the disc 303 in the locking block 32 is pushed to rotate in the circular groove 301. At this time, the resistance spring 302 is compressed, and the limit seat 34 at one end of the push rod 33 passes through the connecting groove 36 and extends, rotating the disc 303 ninety degrees, driving the convex part on the surface of the limit seat 34 to be engaged in the strip groove 37, thereby realizing a fixed connection between the lock body and the cover body 35, without the need for bolt fixing, which is convenient for loading and unloading and maintenance.
[0032] The surface of the screen window body 2 is provided with a mounting groove 6, and the surface of the locking block 32 is integrally processed with a long plate 7, and the long plate 7 is clamped with the mounting groove 6;
[0033] Specifically, a long plate 7 on one side of the lock block 32 is matched with the assembly groove 6 on the surface of the screen window body 2. When the lock block 32 is placed in the groove body 31, the long plate 7 is engaged with the assembly groove 6 to limit the lock body in the correct position.
[0034] In order to facilitate the pulling and adjustment of the screen window body 2, a handle 8 is fixedly installed on one side of the long plate 7.
[0035] The lock body mechanism 5 includes a lock frame 51, a support rod 52, a support spring 53, a clamping block 54 and a push plate 55. The lock frame 51 is embedded in one side of the inner wall of the frame 1, and the support rod 52 is fixedly installed inside the lock frame 51. Two clamping blocks 54 are slidably installed on the surface of the support rod 52, and a push plate 55 is fixedly installed on one side of the two clamping blocks 54. Two support springs 53 are movably sleeved on the surface of the support rod 52. The two support springs 53 are respectively arranged on the top and bottom of the inner wall of the lock frame 51. A paddle portion is fixedly installed on one side of the push plate 55. The clamping block 54 is clamped with the limiting portion 11 in the buckle groove 4.
[0036] It is worth noting that by moving the push plate 55, the clamping block 54 is driven upward, so that the two clamping blocks 54 are respectively disengaged from the two limiting parts 11, and the clamping block 54 will slide on the support rod 52, stretching the bottom support spring 53 and squeezing the top support spring 53, so as to realize the push-pull movement of the screen window body 2. When fixing the screen window body 2, the buckle groove 4 on one side of the screen window body 2 moves to the lock frame 51, and the lock frame 51 enters the buckle groove 4. Since the limiting part 11 in the buckle groove 4 and the clamping block 54 are both inclined, the clamping block 54 is pushed to move upward, and finally the limiting part 11 is limited under the action of the support spring 53, so as to realize the fixation of the screen window body 2.
[0037] In order to enhance the balance of the sliding of the push plate 55 , a balance bar 9 for the sliding of the push plate 55 is fixedly installed inside the lock frame 51 .
[0038] In order to achieve movement, position limitation and anti-dropping of the screen window body 2 in the frame 1 , limit strips 10 for sliding of the screen window body 2 are fixedly installed on the top and bottom of the inner wall of the frame 1 .
[0039] The device puts the lock block 32 into the groove body 31, and places the cover plate on one side of the screen window body 2, pushing the disc 303 in the lock block 32 to rotate in the circular groove 301. At this time, the resistance spring 302 is compressed, and the limit seat 34 at one end of the push rod 33 penetrates the connecting groove 36 and extends, rotating the disc 303 by 90 degrees, driving the convex part on the surface of the limit seat 34 to be engaged in the strip groove 37, realizing the fixed connection between the lock body and the cover body 35, without the need for bolt fixing, which is convenient for loading and unloading maintenance, and the clamping block 54 is driven to move upward by moving the push plate 55, so that the two clamping blocks 54 are respectively disengaged from the two limiting parts 11, and the clamping block 54 will slide on the support rod 52, stretching the bottom support spring 53 and squeezing the top support spring 53 to realize the push-pull movement of the screen window body 2. When fixing the screen window body 2, the buckle groove 4 on one side of the screen window body 2 moves to the lock frame 51, and the lock frame 51 enters the buckle groove 4. Since the limiting part 11 and the clamping block 54 in the buckle groove 4 are both inclined, the clamping block 54 is pushed to move upward, and finally the limiting part 11 is limited under the action of the support spring 53 to realize the fixation of the screen window body 2.
[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
