[0028] Embodiment

[0029] Referring to Figure 1-4 As shown, the utility model discloses a child lock for an entrance door, which includes a doorframe base 10 and a door panel base 20. The doorframe base 10 and the door panel base 20 are provided with mounting holes, and screws are used to lock the doorframe base 10 to the doorframe and the door panel base 20 to the door panel through the mounting holes. The doorframe base 10 includes a positioning shaft, and a locking hook 101 is movably mounted on the positioning shaft. Specifically, the positioning shaft includes a cylindrical base 102 and a locking cover 104. The cylindrical base 102 extends a fixing post 103, and the locking cover 104 is locked to the fixing post 103 by bolts. The locking hook 101 includes first hooks 1012 at both ends and an irregular hole 1011 in the middle. Second hooks 1013 are provided at both ends of the irregular hole 1011 close to the first hooks 1012. During installation, the cylindrical base 102 is locked to the doorframe by screws, the irregular hole 1011 of the locking hook 101 is placed on the fixing post 103, and then it is locked to the fixing post 103 by the locking cover 104, so that the locking hook 101 can move within the fixing post 103, and the first hooks 1012 at both ends can be used to hook the door panel base 20. The two ends of the irregular hole 1011 are used as the extreme positions of both ends of the locking hook 101, that is, the extreme positions when the door panel is opened. Both ends of the locking hook 101 can hook the door panel base 20, and the second hooks 1013 at both ends can support the locking hook 101 to prevent children from pinching their hands when closing the door panel back. It can not only hold the door panel but also prevent the door panel from closing, that is, while preventing children from going out, it can also prevent the problem of children pinching their hands when closing the door for the second time.

[0030] Further, the width of the irregular hole 1011 is smaller than the diameters of the cylindrical base 102 and the locking cover 104, so that the irregular hole 1011 of the locking hook 101 can move within the fixing post 103 without coming out.

[0031] Referring to Figure 1 、 Figure 5-8As shown, the door panel base 20 is provided with a slide groove 201, a slider 202 is slidably arranged in the slide groove 201, and a fixing rod 203 is arranged in the slider 202. Specifically, convex strips 2011 are arranged along the length direction on both sides of the slide groove 201, and the convex strips 2011 are provided with positioning notches 2012, and strip grooves 2021 and blocks 2022 perpendicular to the strip grooves 2021 are arranged on both sides of the slider 202, and the blocks 2022 are pre-tightened in the strip grooves 2021 by springs, and the slider 202 can slide back and forth along the slide groove 201, and when the blocks 2022 are stuck in the positioning notches 2012, the slider 202 is positioned in the slide groove 201 and cannot move. The card block 2022 includes pressing blocks 2023 on both sides of the protruding slider 202. Under normal conditions, the spring pushes the card block 2022 to be locked in the positioning notch 2012. When the slider 202 needs to be slid, the pressing blocks 2023 on both sides are pressed to make the card block 2022 leave the positioning notch 2012 of the convex strip 2011. The convex strip 2011 has two positioning notches 2012. The corresponding slider 202 is at two positions in the slide groove 201, and the corresponding locking hook 101 locks or disengages the fixing rod 203.

[0032] Specific usage process: first press the door frame base 10 to the position near the top of the door frame, install the door panel base 20 near the top of the door panel, slide the slider 202 to allow the lock hook 101 to hook the fixed rod 203, when the child opens the door and pushes it out, the special-shaped hole 1011 of the lock hook 101 will move to one end along the fixed column 103, at this time the lock hook 101 will pull the fixed rod 203 to prevent the door from being opened, and when the child closes the door back, the second hook 1013 will support the fixed column 103, making the door unable to close, to prevent the child from being pinched.

[0033] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
