[0030] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the utility model. The appearance of the phrase in various places in the specification is not necessarily all referring to the same embodiment, nor is it necessarily referring to a particular embodiment in an exclusive sense, as opposed to being independent or alternative embodiments, in combination with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein are combinable with other embodiments.

[0031] In order to enable personnel in the art to better understand the utility model scheme, the technical scheme in the utility model embodiments will be clearly and completely described below in combination with the drawings.

[0032] As shown in the utility model provides an embodiment. Figures 1-5

[0033] ​​​This utility model provides a child-proof door and window handle, primarily used for casement windows. The handle includes a handle 10, a base 20, and a rotating wheel 30. The rotating wheel 30 is installed within the base 20. One end of the handle 10 passes through the base 20 and is rotatably connected to the rotating wheel 30. The base 20 is fixedly installed on the side of the window. Rotating the handle 10 drives the rotating wheel 30 to rotate. Specifically, a limiting piece 40 is provided within the base 20. The limiting piece 40 can engage or disengage with the rotating wheel 30. (Refer to...) Figure 1 As shown, a base cover 22 is detachably installed on the outer wall of the base 20. The base cover 22 can cover the limiting piece 40 to prevent children from accidentally touching it. After removing the base cover 22, the user can adjust the position of the limiting piece 40, thereby changing the connection state between the limiting piece 40 and the rotating wheel 30. (Refer to...) Figure 2 As shown, when the limiting plate 40 and the rotating wheel 30 are separated, the limiting plate 40 does not limit or block the rotating wheel 30, and turning the handle 10 can drive the rotating wheel 30 to rotate. When the limiting plate 40 and the rotating wheel 30 are engaged, the limiting plate 40 limits and blocks the rotating wheel 30, making both the rotating wheel 30 and the handle 10 unable to rotate. Users can lock the rotating wheel 30 with the limiting plate 40 according to actual usage needs. With the obstruction of the base cover 22, it is difficult for children to find and move the limiting plate 40 inside the base 20, thus making it less likely for children to accidentally operate the door and window handles when they are not under adult supervision, thereby reducing or avoiding safety accidents.

[0034] Specifically, a lever 41 is connected to the limiting plate 40, and a clearance opening 21 is provided on the base 20. The lever 41 extends out of the base 20 through the clearance opening 21, and moving the lever 41 can cause the limiting plate 40 to slide. It is understood that the length of the lever 41 extending out of the clearance opening 21 is not prominent, just enough for an adult to pry it with their finger. Moreover, the lever 41 is smaller in size and less conspicuous in position than the handle 10. Children who need constant adult supervision will not easily notice the lever 41, nor will they easily operate the lever 41, thereby achieving the effect of preventing children from accidentally operating it.

[0035] Furthermore, the base cover 22 snaps into the base 20 for easy assembly and disassembly. The base cover 22 completely covers the clearance opening 21 and the lever 41, preventing the lever 41 from being exposed on the base 20. This makes it difficult for children to notice and accidentally operate the lever 41. (Refer to...) Figure 1As shown, when the dial lever 41 needs to be dialed, the user can first detach the base cover 22 from the base 20, and then rotate the base cover 22 around the handle 10 shaft by a certain angle to expose the dial lever 41, without the need to completely detach the base cover 22. The upper end of the base 20 is provided with a notch 23 at the connection between the base cover 22 and the base 20, which is convenient for adults to use their fingers to pry open the base cover 22 to dial the dial lever 41. The notch 23 is located at the upper end of the base 20, which is also less likely to be found from the perspective of children.

[0036] Specifically, a plurality of protrusions 31 are arranged around the circumferential side wall of the rotating wheel 30, and the lower end of the limiting sheet 40 is provided with a plurality of recesses 42, the size and shape of the protrusions 31 and the recesses 42 are matched, and the recesses 42 can be respectively matched with the plurality of protrusions 31. When the recess 42 is matched with one of the protrusions 31, the rotating wheel 30 cannot rotate, otherwise, the rotating wheel 30 can rotate.

[0037] Further, a plurality of positioning grooves 32 are arranged around the circumferential side wall of the rotating wheel 30, and the base 20 is provided with a plurality of elastic top beads 24, which can be respectively matched with the plurality of positioning grooves 32. The positions of the positioning grooves 32 correspond to the positions of the protrusions 31. When the elastic top bead 24 is matched with any one of the positioning grooves 32, one of the protrusions 31 is aligned with the recess 42. The user can determine whether the protrusion 31 is aligned with the recess 42 according to the connection state of the elastic top bead 24 and the positioning groove 32. It can be understood that the connection between the elastic top bead 24 and the positioning groove 32 can be separated when the user rotates the handle 10 with force. In addition, in order to facilitate the user to determine the connection state of the elastic top bead 24 and the positioning groove 32, a plurality of transition grooves 33 with relatively shallow depth can be evenly arranged between every two positioning grooves 32, so that the elastic top bead 24 will collide with the transition grooves 33 one by one during the rotation of the rotating wheel 30, and the user can distinguish the different sounds generated by the collision of the elastic top bead 24 with the transition grooves 33 and the positioning grooves 32.

[0038] Further, the two side edges of the limiting sheet 40 are respectively provided with sliding grooves 43, and the two inner walls of the base 20 are respectively provided with limiting blocks 25, which are connected with the sliding grooves 43 in a sliding manner, so that the limiting sheet 40 can slide up and down in a straight line direction. The limiting block 25 and the sliding groove 43 are tightly matched, so that the limiting sheet 40 will not slide by itself under the action of its own gravity, and can only slide by the force of dialing the dial lever 41. In addition, the end of the sliding groove 43 is provided with a notch 44, the size of which is matched with the limiting block 25, and the limiting block 25 can pass through the notch 44, which is convenient for disassembling the limiting sheet 40.

[0039] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing specific embodiments, or equivalently replace some of the technical features. Any equivalent structure made by using the content of the present application specification and drawings, directly or indirectly used in other related technical fields, is also within the patent protection scope of the present application.
