Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a child-safe door and window device. Background Technology

[0002] The original purpose of door and window design was mainly to meet the basic needs of ventilation, lighting, and separation of indoor and outdoor spaces. However, with social development and the improvement of people's living standards, especially for families with children, the safety performance of traditional doors and windows has gradually become prominent. In daily life, children are naturally active and curious about their surroundings. They like to explore and play with doors and windows. Because traditional doors and windows are often not designed with children's safety in mind and lack effective protective measures, windows may be opened by accident, posing safety hazards such as children falling out of windows, which brings potential dangers to children.

[0003] Traditional doors and windows often lack limiting devices, making it easy for children to fully open sliding windows while playing, exposing them to the window edge and significantly increasing the risk of falls, seriously threatening their lives. While other doors and windows may have limiting devices, most rely on fixed clips. Although this method can control the opening position of the sliding window to some extent, it is very cumbersome when users need to fully open the sliding window for ventilation, cleaning, or other needs. It requires complex disassembly of the fixed clips, which is time-consuming and laborious, causing great inconvenience to users. This not only affects the normal use efficiency of doors and windows but also reduces users' willingness to use limiting devices. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a child-safe door and window device that solves the problem that traditional door and window safety limit devices are fixed, preventing windows from being fully opened.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a child-safe door and window device, comprising a sliding window that slides within a frame and a fixed window that is fixed within the frame. The top and bottom of the frame cavity are provided with slide rails that cooperate with the sliding window. A groove is provided on one side of the bottom of the sliding window, and a positioning rod is slidably connected within the groove. A positioning lock hole is provided in the lower slide rail that cooperates with the positioning rod. A push rod is fixedly connected to the front side of the positioning rod, and one end of the push rod passes through the sliding window and extends to the front side of the sliding window. A through groove is provided on the front side of the sliding window that cooperates with the push rod.

[0006] Preferably, a sliding cylinder is fixedly connected to one side of the sliding window surface via a connecting rod. A sliding rod is slidably connected inside the sliding cylinder. A sliding groove plate is fixedly connected to the top of the sliding rod. Sliding blocks are slidably connected to the upper and lower parts of the inner cavity of the sliding groove plate. A limiting rod is fixedly connected to the rear side of the sliding block. A protrusion is fixedly connected to the opposite sides of the two limiting rods. A limiting groove is provided on the front side of the positioning rod to cooperate with the limiting rod and the protrusion. A through groove is provided on the front side of the sliding window to cooperate with the limiting rod and the protrusion. A spring is fixedly connected between the two limiting rods.

[0007] Preferably, a locking rod is rotatably connected to the bottom of the upper limiting rod via a rotating component, and a groove for cooperating with the locking rod is provided on one side of the top of the lower limiting rod.

[0008] This utility model provides a child-safe door and window device. It has the following beneficial effects:

[0009] This invention utilizes the cooperation between a positioning rod, a positioning lock hole, and a push rod. When the positioning rod is inserted into the positioning lock hole, the sliding window cannot slide, thus restricting the sliding window and preventing children from sliding it at will. Simultaneously, through the cooperation between the sliding cylinder, sliding rod, sliding groove plate, slider, limiting rod, protrusion, limiting groove, and spring, when it is necessary to continue opening the sliding window, the limiting rod is simultaneously pressed and pulled, causing the limiting rod and protrusion to disengage from the limiting groove. Then, the positioning rod can be pushed upwards by the push rod, disengaging it from the positioning lock hole, allowing the sliding window to continue moving. This significantly reduces the possibility of children being injured by the sliding window sliding, ensuring that children cannot open the sliding window at will, providing reliable safety protection for children, while also allowing adults to easily open the window when needed, meeting normal ventilation and usage needs.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a child-safe door and window device, including a sliding window 2 that slides within a frame 1 and a fixed window 16 that is fixed within the frame 1. The top and bottom of the inner cavity of the frame 1 are provided with slide rails 5 that cooperate with the sliding window 2. A slide groove 3 is provided on one side of the bottom of the sliding window 2. A positioning rod 4 is slidably connected in the slide groove 3. A positioning lock hole 6 that cooperates with the positioning rod 4 is provided in the lower slide rail 5. A push rod 7 is fixedly connected to the front side of the positioning rod 4. One end of the push rod 7 passes through the sliding window 2 and extends to the front side of the sliding window 2. A through groove that cooperates with the push rod 7 is provided on the front side of the sliding window 2.

[0018] To further limit the positioning rod 4, a sliding cylinder 8 is fixedly connected to one side of the surface of the sliding window 2 via a connecting rod. A sliding rod 9 is slidably connected inside the sliding cylinder 8. A sliding groove plate 10 is fixedly connected to the top of the sliding rod 9. A slider 11 is slidably connected to the upper and lower parts of the inner cavity of the sliding groove plate 10. A limiting rod 12 is fixedly connected to the rear side of the slider 11. A protrusion 13 is fixedly connected to the opposite sides of the two limiting rods 12. A limiting groove 14 is opened on the front side of the positioning rod 4 to cooperate with the limiting rod 12 and the protrusion 13. A through groove is opened on the front side of the sliding window 2 to cooperate with the limiting rod 12 and the protrusion 13. A spring 15 is fixedly connected between the two limiting rods 12.

[0019] It should be noted that the squeezing and gripping force required for spring 15 is set to exceed the normal strength range that children can achieve. This ensures that even if children are curious about the door and window device and try to operate it during their daily activities, they will not be able to squeeze the spring with their own strength and thus will not be able to complete the release operation. This effectively avoids the safety hazards caused by children opening doors and windows on their own.

[0020] To further prevent children from squeezing the limiting rod 12, a locking rod 17 is rotatably connected to the bottom of the upper limiting rod 12 via a rotating component. A groove 18 is provided on one side of the top of the lower limiting rod 12 to cooperate with the locking rod 17. The groove 18 is an open groove, and the end of the locking rod 17 is made of rubber to ensure that it can fit tightly with the groove 18 and prevent the locking rod 17 from shaking.

[0021] In use, the user moves the sliding window 2 a specified distance, inserts the positioning rod 4 into the positioning lock hole 6 using the push rod 7, and simultaneously presses the limiting rod 12 against each other. The two limiting rods 12 move closer together and are pushed inward. When the two limiting rods 12 move into the limiting groove 14, the limiting rods 12 are released. Under the elastic force of the spring 15, the two limiting rods 12 drive the protrusion 13 to simultaneously extend into the limiting groove 14. Then, the locking rod 17 is moved to engage the groove 18, thus ensuring that children cannot open the sliding window at will. When it is necessary to move the sliding window 2, the locking rod 17 is moved to disengage it from the groove 18. At the same time, the limiting rods 12 are pressed against each other, move closer together, and pull the limiting rods 12 outward, so that the limiting rods 12 and the protrusion 13 disengage from the limiting groove 14. Then, the positioning rod 4 can be pushed upward using the push rod 7, and the positioning rod 4 disengages from the positioning lock hole 6, allowing the sliding window 2 to continue to move.
