Technical Field

[0001] The utility model relates to the technical field of safety locks, in particular to a window safety lock. Background Art

[0002] The window safety lock is a lock body specially installed for windows. It is suitable for home users who push windows horizontally. Its main purpose is to prevent babies from pushing the window open too much out of curiosity and climbing out of the window to cause accidents by blocking the opening distance of the window without affecting the appearance of the window. It is a safety protection tool.

[0003] The prior art publication number CN218912551U provides a child safety lock for windows, which belongs to the technical field of safety locks. It includes an outer frame, a fixed frame fixed to one end of the outer frame, and a movable frame slidingly arranged in the outer frame; it also includes a locking track fixedly installed on the outer frame along the sliding direction; a fingerprint lock installed at the other end of the movable frame and adapted to the locking track. When the fingerprint lock recognizes the recorded fingerprint, the fingerprint lock switches to the open state, and the movable frame slides to any position of the locking track under the action of external force, the fingerprint lock switches to the locked state, and the movable frame is repositioned; otherwise, the fingerprint lock is always in the locked state. The utility model provides a window safety lock that can control the size of the window opening to meet ventilation needs, and can effectively distinguish whether the operator has the operating authority. Only adults who have entered the management system can open this safety lock to prevent children from accidentally opening the window and falling from the building.

[0004] In the above patent, the purpose of fixing the window when ventilating is achieved mainly by adding a locking track and inserting a protruding lock tongue into the groove in the locking track. However, this method of fixing the window is due to the fact that the entire safety lock is installed on the surface of the window, and the safety lock is generally used in families with children. This will cause when a child who loves to run accidentally approaches the edge of the window, he will directly hit the safety lock, resulting in more serious consequences, which greatly reduces the anti-collision safety performance of the child safety lock of the window. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a window safety lock, which solves the technical problems such as insufficient anti-collision safety performance of child safety locks on windows.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example

[0024] The following is combined with Figure 1 -Attached Figure 6, further details of this application are given. A window safety lock includes a lock body 1, which is arranged in a window frame. A slide rail for limiting the position of the lock body 1 is arranged in the window frame. The lock body 1 includes a main cover plate 16 fixed to the lower side of the window frame, and a plurality of sliding covers 11 slidably mounted on the main cover plate 16. The sliding covers 11 are slidably connected to each other, and the sliding covers 11 are a cover structure with large sections gradually becoming small sections. The main cover plate 16 and the sliding covers 11 are locked by a first limiting member 13, and the sliding covers 11 are locked by a second limiting member 14. The first limiting member 1 3 and the second limiting member 14 are detachable, a sliding groove 12 is provided at the center of the side of the sliding sleeve 11 close to the ground, a bolt limiting member 15 is movably installed at the position of the main sleeve 16 close to the second limiting member 14, a connecting plate 117 is installed on the side of the lock body 1 close to the window frame, and a movable shaft groove 116 is provided on the side of the connecting plate 117 away from the window frame. A fixing strip 114 is fixedly installed on the side of the sleeve of the lock body 1 close to the connecting plate 117 away from the connecting plate 117, and the fixing strip 114 is fixed on the end away from the sleeve. A movable shaft 115 is installed, and the movable shaft 115 and the movable shaft groove 116 are inserted into each other. A straight notch is opened on both sides of the connecting plate 117 that are different from the movable shaft groove 116. A plurality of rotating shafts 119 are fixedly installed in the straight notch of the connecting plate 117. A rotating wheel 118 is rotatably installed in the middle position of the rotating shaft 119. The rotating wheel 118 fits the edge of the slide rail. The lock body 1 is provided with a threaded groove 112 on a sleeve plate closest to the window frame 2. The bolt limiter 15 includes a threaded shaft 151 and a knob 152. The button 152 is fixedly mounted on the side of the threaded shaft 151 away from the slide rail, and the threaded shaft 151 cooperates with the threaded groove 112 to rotate threadedly. The lock body 1 is provided with a sliding groove 111 between the large and small section sleeves. The first limit member 13 includes a limit frame 131 and a pull ring 132. The pull ring 132 is fixedly mounted on the side of the limit frame 131 away from the slide rail, and the limit frame 131 is movably nested in the sliding groove 111. The combining plate 117 is U-shaped, and the lock body 1 is provided with an inward displacement groove 113 at the center position of one side of each section sleeve close to the slide rail.

[0025] Among them, the lock body 1 is not just a four-section structure as shown in the figure. The operator can appropriately increase or decrease the number of sections of the lock body 1 according to the specific usage. However, the internal limiter and bolt limiter structure remain unchanged. The corresponding first limiter can be installed according to the corresponding number of sections.

[0026] The reserved distance at the top of the sliding groove 111 is larger than the distance at the bottom of the limiting frame 131, so that when the entire limiting frame 131 moves upward to the top, the smaller sleeve can slide smoothly into the adjacent larger sleeve.

[0027] The rotating wheel 118 is always in contact with both sides of the window rail, so that when the lock body 1 moves in the rail 4 , the lock body 1 can move more smoothly in the window rail through the rotating wheel 118 .

[0028] The corresponding position of the movable shaft 115 is consistent with the position of the movable shaft groove 116, so that the sleeve in the lock body 1 can move more precisely when moving.

[0029] The working principle of the present invention is described as follows: when the window safety lock is in use, the user only needs to place the slide groove 12 and the inner moving groove 113 of the entire lock body 1 on the window slide rail to complete the installation of the entire window safety lock. Since the height of the window safety lock will not exceed the window frame, the lock body 1 is basically in a hidden state when in use, which can effectively prevent children from touching it. When the user needs to open the window for ventilation, he only needs to pull the first limit piece 13 on the smallest set plate upward through the pull ring 132. At this time, the limit frame 131 moves upward along the sliding groove 111 until the bottom end of the limit frame 131 is located at the top end of the sliding groove 111. At this time, the movable window can be pulled a short distance. When continuing to pull the movable window, it will be blocked by the next second limit piece 14. When the user wants to continue to open the window, he will follow The above steps continue to pull the second limit member 14. When the user needs to pull up the window to a greater extent, he only needs to turn the knob 152 by hand. At this time, the rotation of the knob 152 will cause the threaded shaft 151 to rotate in the threaded groove 112 until the threaded shaft 151 does not affect the movement of the front cover plate. The user can then pull the sliding window open to a greater extent along the window slide rail. When the cover plate in the lock body 1 moves inward, it enters the moving shaft body 115 through the moving shaft groove 116 to limit the movement. The rotation of the wheel 118 on the rotating shaft 119 can make the combining plate 117 move more smoothly on the slide rail 4. In this way, when the window safety lock is in use, it can avoid being touched by children, and the user can control the opening distance of the window safety lock at will, thereby greatly improving the practicality of the window safety lock.

[0030] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
