Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see the appendix Figure 1-4 A child safety lock structure according to an embodiment of the present utility model includes a connecting seat 1, a cover 3 detachably connected to the connecting seat 1, a connecting strap 2 connecting the connecting seat 1 and the cover 3, and a base 4 provided below the cover 3. When the cover 3 and the base 4 are connected to each other, they are locked. During installation, the base 4 is connected to the movable end, i.e., the drawer, cabinet door, or refrigerator door. The connecting seat 1 can be installed on the fixed end or the movable end, i.e., the cabinet, the side of the refrigerator, or one of the doors of a double door.

[0032] The base 4 includes a fixed seat 41, a knob 42 is rotatably connected to the middle of the fixed seat 41, and a semi-circular plate 45 is slidably connected to the inner side of the knob 42. By rotating the knob 42, the semi-circular plate 45 can extend out of the knob 42 or retract into the knob 42 to achieve locking or unlocking. The operation steps are simple.

[0033] The bottom of the cover 3 is fixedly connected to a card holder 31. The card holder 31 has an annular opening 32 on its outer side. When locked, the annular opening 32 and the semicircular plate 45 cooperate with each other. Therefore, no matter what angle the cover 3 is connected to the fixed seat 41, the semicircular plate 45 can limit the card holder 31, which can improve the convenience of use.

[0034] Example 2

[0035] Based on Example 1, please refer to the appendix. Figure 2-4The fixed base 41 has a groove 43 on its upper part, and a connection port 49 is provided on one side of the groove 43. The connection port 49 is connected to the semi-circular plate 45. When the knob 42 is rotated, the connection port 49 can press against the arc surface of the semi-circular plate 45, causing it to retract into the knob 42 to unlock. When the semi-circular plate 45 is aligned with the connection port 49, it can automatically pop out to lock.

[0036] The knob 42 is circular in shape. A limiting cavity 48 is formed on one side of the knob 42. A limiting plate 46 is fixedly connected to one side of the semi-circular plate 45 inside the limiting cavity 48. A support spring 47 is fixedly connected between the limiting cavity 48 and the limiting plate 46. When compressed, the semi-circular plate 45 and the limiting plate 46 compress the support spring 47, so that the semi-circular plate 45 can retract into the knob 42. The limiting cavity 48 limits the limiting plate 46, which can prevent the semi-circular plate 45 from protruding too much. At the same time, the limiting plate 46 guides and limits the pop-out direction of the semi-circular plate 45 to ensure stability during use.

[0037] The knob 42 is embedded in the fixed base 41. The fixed base 41 has notches 9 on both the upper and lower sides. The notches 9 on both sides allow the knob 42 to be exposed, making it easy to rotate. At the same time, when locked, the cover 3 can block the notches 9, making them hidden and not easily discovered by children. The outer ring of the knob 42 is fixedly connected with multiple anti-slip strips 44 that are evenly spaced, which can improve the user experience.

[0038] Both the fixing base 41 and the connecting base 1 are connected to the bottom of the adhesive body 7. The outer side of the adhesive body 7 is connected to the release paper 8. During installation, the adhesive body 7 is exposed by tearing off the release paper 8 and then bonded and fixed to furniture or other objects.

[0039] An opening 5 is provided on the outer side of the connecting seat 1. When unlocked, the cover 3 is rotatably connected to the connecting seat 1 under the action of connecting strap 1 2 and connecting strap 2 6, and rotates downward under the action of gravity. When opening or closing drawers or cabinet doors, it will not obstruct them. Connecting strap 2 6 is rotatably connected inside the opening 5. One side of connecting strap 2 6 is fixedly connected to connecting strap 1 2. Both connecting strap 2 6 and connecting strap 1 2 are made of flexible material. Therefore, the child lock can adapt to both flat installation and corner installation, and is suitable for use in multiple scenarios such as refrigerators, drawers, cabinet doors, and water dispensers.

[0040] The mounting base 41 is located inside the knob 42 and is fixedly connected to multiple damping strips 10. The multiple damping strips 10 are spaced apart to increase the damping feel and prevent the knob 42 from rotating on its own.

[0041] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
