Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a child safety escape lock that is adaptable to windows of different sizes. Background Technology

[0002] Children, being naturally active, often climb everywhere. Many parents, due to momentary negligence, fail to keep a close eye on their children, who sometimes open windows and try to climb out. This can easily lead to falls and other accidents with very serious consequences. Therefore, there is a need for child locks on doors and windows that can limit the opening of windows to a size that allows a child to crawl through, ensuring children's safety. Currently, child locks on the market have fixed sizes and poor adaptability. Furthermore, in emergencies, home security and anti-theft facilities should not become obstacles to escape. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a child safety escape lock that is adaptable to windows of different sizes.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a child safety escape lock adaptable to windows of different sizes, comprising a mounting base, a telescopic connecting rod, and a window connector. One end of the telescopic connecting rod is hinged to the mounting base, and the other end is hinged to the window connector. The mounting base is provided with a limiting part to restrict the rotation angle of the telescopic connecting rod. The mounting base includes a base and a connector detachably mounted on the base. A transverse locking structure is provided between the connector and the base. The transverse locking structure includes a transverse locking port and a locking member provided on the connector. The transverse locking port includes a transverse locking opening and a movable opening. A locking opening is provided on the base directly below the transverse locking opening. The locking member includes a top cap and a rod portion. The rod portion of the locking member passes through the locking opening, and its top cap is placed in the transverse locking opening. The distance between the connection positions of the transverse locking opening and the movable opening is less than the diameter of the top cap. A longitudinal locking structure is also provided between the connector and the base.

[0005] Furthermore, a protrusion is provided at the lower part of the lateral locking port, and the top cap is placed on the protrusion.

[0006] Furthermore, the end of the connector away from the lateral locking structure extends forward and upward to form a connecting portion, and the connection position between the connecting portion and the connector forms a limiting portion.

[0007] Furthermore, the longitudinal locking structure includes a hinge, a mounting port on the connecting part, and a longitudinal locking port on the base, wherein the longitudinal locking port includes a communicating longitudinal locking port and an unlocking port.

[0008] Furthermore, the mounting port is located directly above the longitudinal locking port, the hinge is mounted on the mounting port, the hinge passes through the longitudinal locking port, and a locking plate is provided at the bottom of the hinge. The diameter of the locking plate is greater than the width of the longitudinal locking port, and the diameter of the locking plate is smaller than the diameter of the unlocking port.

[0009] Furthermore, the telescopic link includes an upper link and a lower link, with sliding rails provided on both sides of the upper link, and the lower link inserted into the sliding rails.

[0010] Furthermore, the lower connecting rod is provided with a long strip-shaped limiting channel, and the bottom of the upper connecting rod is provided with a limiting block that is inserted into the limiting channel.

[0011] The beneficial effects of this utility model are as follows: 1. A telescopic connecting rod is provided between the mounting base and the window connector, reducing the overall length, so that this product can be used not only for ordinary large windows, but also flexibly for small windows, and has better adaptability; 2. In an emergency, when it is necessary to remove the function that restricts the opening angle, the locking part is taken out upward to release the lateral lock, and then the connecting part is moved laterally so that the hinge part enters the unlocking port and releases the longitudinal lock upward, so that the connecting part can be separated from the mounting base to release the window opening angle restriction.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Example: A child safety escape lock adaptable to windows of different sizes includes a mounting base 1, a telescopic link 2, and a window connector 3. One end of the telescopic link 2 is hinged to the mounting base 1, and the other end is hinged to the window connector 3. The overall length of the telescopic link 2 can be adjusted, making this product suitable not only for ordinary large windows but also for small windows. The mounting base 1 is provided with a limit part 55 to limit the rotation angle of the telescopic link 2, thereby limiting the opening angle of the door and window, preventing children from opening the window too wide and crawling out, thus preventing accidents. The mounting base 1 includes a base 4 and a connector 5 detachably mounted on the base 4. The detachable connection between the base and the connector facilitates installation and allows for quick release of the window opening angle restriction. A lateral locking structure is provided between the connector 5 and the base 4. The lateral locking structure includes a lateral lock slot 51 and a locking element 6 provided on the connector 5. The horizontal locking port 51 includes a horizontal locking port 511 and a movable port 512. A locking port 42 is provided on the base 4 directly below the horizontal locking port 51. The locking member 6 includes a top cap 61 and a rod 62. The rod 62 of the locking member 6 passes through the locking port 42, and its top cap 61 is placed in the horizontal locking port 511. The distance between the connection positions of the horizontal locking port 511 and the movable port 512 is smaller than the diameter of the top cap 61. The top cap 61 cannot directly pass through the connection position of the horizontal locking port 511 and the movable port 512 to enter the movable port 512. Thus, the connecting member 5 cannot move laterally when the top cap 61 is not pulled out. A longitudinal locking structure is also provided between the connecting member 5 and the base 4. The longitudinal locking structure restricts the connecting member 5 from being pulled out directly upward before the top cap 61 is pulled out. In conjunction with the horizontal locking structure, it can prevent children from easily releasing the window opening angle restriction.

[0018] Furthermore, a protrusion 52 is provided at the lower part of the horizontal locking opening, and the top cap 61 is placed on the protrusion 52. The protrusion 52 creates a gap between the top cap 61 and the base 4. When it is necessary to release the window opening angle restriction, the user can conveniently remove the locking part 6 from the gap to release the restriction.

[0019] Furthermore, the end of the connector 5 away from the lateral locking structure extends forward and upward to form a connecting part 54. The connection position between the connecting part 54 and the connector 5 forms a limiting part 55. The telescopic link 2 is located between the connecting part 54 and the base 4. When the window is opened, the telescopic link 2 contacts the limiting part 55 to limit the opening angle and prevent the opening angle from being too large.

[0020] Furthermore, the longitudinal locking structure includes a hinge 7, a mounting port 53 on the connecting part 54, and a longitudinal locking port 41 on the base 4. In this embodiment, the hinge 7 can be a rivet. The longitudinal locking port 41 includes a connected longitudinal locking port 411 and an unlocking port 412. The mounting port 53 is located directly above the longitudinal locking port 411. The hinge 7 is mounted on the mounting port 53 and passes through the longitudinal locking port 411. A locking plate 71 is provided at the bottom of the hinge 7 and is located below the base. The diameter of the locking plate 71 is larger than the width of the longitudinal locking port 411. When the hinge 7 is located in the longitudinal locking port, the connecting member 5 cannot be pulled upward due to the obstruction of the locking plate 71. The diameter of the locking plate 71 is smaller than the diameter of the unlocking port 412. When the hinge 7 moves laterally to the unlocking port, the longitudinal movement restriction of the connecting member 5 is released.

[0021] When the window opening restriction needs to be lifted, the locking member 6 is pulled upward through the gap formed between the top cap 61 and the base 4 to release the lateral movement restriction of the connecting member 5. When the connecting member 5 moves laterally, the hinge member 7 moves to the unlocking port 412, releasing the longitudinal movement restriction of the connecting member 5. The connecting member 5 can be pulled upward directly to separate from the base 4, thereby releasing the window opening angle restriction.

[0022] Furthermore, the telescopic link 2 includes an upper link 8 and a lower link 9. The upper link 8 has sliding rails 81 on both sides, and the lower link 9 is placed in the sliding rails 81, allowing the lower link 9 to slide within the sliding rails 81.

[0023] Furthermore, the lower connecting rod 9 is provided with a long strip-shaped limiting channel 91, and the bottom of the upper connecting rod 8 is provided with a limiting block 82 that is inserted into the limiting channel 91 to prevent the lower connecting rod 9 from directly dislodging from the sliding track 81.
