Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door and window accessories, in particular to a child lock device. Background Technique
[0002] Windows are divided into enclosing components or partitioning components according to their positions, and have different design requirements, respectively having functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fire prevention. New requirements are energy conservation. In cold regions, the heat loss through door and window gaps accounts for about 25% of the total heating heat consumption.
[0003] When people choose windows, they will consider the safety of doors and windows. Most existing windows lack a locking mechanism and have low safety. Especially when there is no adult at home, children may open the window to look out and accidentally fall downstairs, causing accidents. Moreover, the opening angle of the window cannot be limited. When only a small angle of ventilation is needed, the window opens too wide, and improvements are needed in this regard. Content of the Utility Model
[0004] The purpose of the utility model is to provide a child lock device to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A child lock device includes a first mounting seat and a second mounting seat. There are two inclined upright frames on the surface of the first mounting seat. An activity kit is rotatably installed between the two upright frames. A support rod is movably inserted into the activity kit. A row of positioning holes is opened on the support rod. A positioning component is arranged on the outer surface of the activity kit. A connecting frame is arranged on the side wall of the second mounting seat. One end of the support rod is rotatably connected to the connecting frame.
[0006] Preferably, mounting holes are opened at both ends of the first mounting seat and the second mounting seat.
[0007] Preferably, the positioning component includes a fixed block. A plug rod is movably inserted into the fixed block. The bottom end of the plug rod passes through the activity kit and is inserted into the positioning hole. A pressing plate is arranged on the plug rod. A compression spring is sleeved outside the plug rod. The bottom end of the compression spring presses on the pressing plate.
[0008] Preferably, the support rod is of a two-section structure. The two sections of the support rod are connected by a connecting belt. A plug hole is arranged inside the section connected to the connecting frame. The inner wall of the plug hole is a magnet. An inner rod is movably inserted into the support rod. The end of the inner rod is an iron block. The end of the inner rod is inserted into the plug hole.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] A child lock device proposed by the present utility model installs the first mounting base on the window frame and the second mounting base at the edge of the window sash. When opening and closing the window, the support rod moves within the movable kit, and the length of the support rod limits the opening angle of the window. At the same time, positioning holes and positioning components are provided to facilitate the control of the opening and closing angles of the window, making it safer and more convenient to use.

Detailed Embodiment
[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0016] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a child lock device, which includes a first mounting seat 1 and a second mounting seat 8. Mounting holes are provided at both ends of the first mounting seat 1 and the second mounting seat 8, and the device is installed at a specified position through screws. There are two inclined upright frames 2 on the surface of the first mounting seat 1. An activity kit 3 is rotatably installed between the two upright frames 2. A support rod 4 is movably inserted into the activity kit 3. One end of the support rod 4 is provided with a baffle plate to prevent it from passing through the activity kit 3. A row of positioning holes 5 are provided on the support rod 4. A positioning component is provided on the outer surface of the activity kit 3. The positioning component includes a fixed block 6. A plug rod 7 is movably inserted into the fixed block 6. The bottom end of the plug rod 7 passes through the activity kit 3 and is inserted into the positioning hole 5. A pressing plate 701 is provided on the plug rod 7. A compression spring 702 is sleeved outside the plug rod 7. The bottom end of the compression spring 702 presses on the pressing plate 701. Lift the plug rod 7 upward so that the bottom end of the plug rod 7 is removed from the positioning hole 5, and the support rod 4 can move within the activity kit 3. When the opening angle of the window is adjusted, the compression spring 702 pushes the pressing plate 701 downward so that the plug rod 7 is inserted into the corresponding positioning hole 5, and then the support rod 4 can be fixed, and the opening angle of the window is also fixed.
[0017] A connecting frame 9 is provided on the side wall of the second mounting seat 8. One end of the support rod 4 is rotatably connected to the connecting frame 9. The support rod 4 is of a two-section structure. A connecting groove is provided between the two sections of the support rod 4. A connecting belt 402 is connected in the connecting groove. An insertion hole is provided in the section connected to the connecting frame 9. The inner wall of the insertion hole is a magnet. An inner rod 401 is movably inserted into the support rod 4. The end of the inner rod 401 is an iron block. The end of the inner rod 401 is inserted into the insertion hole. When the window is completely closed, the first mounting seat 1 and the second mounting seat 8 are attached together. At this time, the protruding angle of the support rod 4 is too long. The inner rod 401 can be pulled outwards for a certain distance so that the inner rod 401 is pulled out from the upper section of the support rod 4. At this moment, this part of the support rod 4 protruding from the activity kit 3 can be bent to reduce the occupied space and be more convenient and safe.
[0018] During actual use, the first mounting seat 1 is installed on the window frame, and the second mounting seat 8 is installed at the edge of the window sash. When opening and closing the window, the support rod 4 moves within the activity kit 3. The length of the support rod 4 limits the opening angle of the window, reducing the occurrence of accidents when children are near the window. At the same time, positioning holes 5 and a positioning component are provided, which are convenient for controlling the opening and closing angles of the window and are safer and more convenient to use.
[0019] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
