DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are parts of, but not all of, the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments derived by those of ordinary skills in the art without creative effort fall within the scope of protection of the present disclosure. Accordingly, the following detailed description of the embodiments of the present disclosure shown in the drawings is not intended to limit the scope of protection of the present disclosure, but merely to represent selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments derived by those of ordinary skills in the art without creative effort fall within the scope of protection of the present disclosure.

[0019] In the description of the present disclosure, the terms “first”, “second” are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of indicated technical features. Thus, a characteristic that is referred to by “first” and “second” may include, expressly or implicitly, one or more of the characteristics. Also, in the description of the present disclosure, the phrase “a plurality of” means two or more, unless otherwise specified.

[0020] Referring to FIG. 1, an infant bed includes a bed body 10 and two support units symmetrically arranged on the bed body 10. Each support unit includes a lifting assembly 30 and a retaining assembly 20. The bed body 10 is fixedly arranged on the lifting assembly 30. The retaining assembly 20 includes first support rods 21. The lifting assembly 30 includes a hollow fixing seat 31 fixedly arranged on the top of the first support rods 21 and a lifting mechanism 32 passing through the hollow fixing seat 31. A surface of the hollow fixing seat 31 facing the bed body 10 is provided with a plurality of engagement holes 311 arranged along a longitudinal direction. The lifting mechanism 32 includes a lifting handle 321, a hollow shell 322, a pulling wire 323, a first spring 324, a pulling member 325, a second spring 326, and an engagement element 327. The pulling wire 323 is connected between the lifting handle 321 and the pulling member 325. The first spring 324 is arranged around an end of the pulling wire 323 near the pulling member 325, two ends of the first spring 324 are respectively pressed against the pulling member 325 and the shell 322. The pulling member 325 has a first inclined surface 3251 along the direction of the pulling wire 323. The shell 322 has a first through hole 3221. The engagement element 327 is forced by the second spring 326 to partially extend out from the first through hole 3221 and is engaged with one of the engagement holes 311. The engagement element 327 has a second inclined surface matched with the first inclined surface 3251.

[0021] When the user pulls the lifting handle 321 and then moves the pulling wire 323 through the lifting handle 321, the pulling wire 323 makes the pulling member 325 move upward, so the first inclined surface 3251 moves relative to the second inclined surface to compress the second spring 326, so that the engagement element 327 is drawn back within the first through hole 3221 and separated with the engagement hole 311. Meanwhile, the lifting mechanism 32 is pulled upward or the lifting mechanism 32 moves downward under the action of the gravitational force, and then when there is no force applied to the lifting handle 321, the first spring 324 pushes the pulling member 325 to return back to the initial position. At the moment, the second spring 326 pushes the engagement element 327 to extend out from the first through hole 3221 again and gets engaged with the engagement hole 311. In addition, by adjusting the lifting assembly 30 at one side of the bed body, the bed body 10 can be lifted at one side and become inclined.

[0022] As a further improvement, the first support rods 21 are arranged in a form of a triangular shape and support a bottom portion of the hollow fixing seat 31.

[0023] As a further improvement, the retaining assembly 20 further includes a first crossbar 22, the first crossbar 22 laterally supports the first support rods 21.

[0024] As a further improvement, the retaining assembly 20 further includes a second crossbar 23, the second crossbar 23 laterally supports the first crossbars 22.

[0025] As a further improvement, the retaining assembly 20 further includes a support frame 24 for supporting the bed body 10. The support frame 24 is mounted between the support units through support grooves 312 provided at the bottom portion of the shell 322.

[0026] As a further improvement, the retaining assembly 20 further includes sliding wheels 25 and friction pads 26 provided at the bottom portion of the first support rods 21. The sliding wheels 25 and friction pads 26 are located on the same plane. By arranging the sliding wheels 25 and friction pads 26 on the same plane, the infant bed can be prevented from sliding back and forth when the bed is placed horizontally. In addition, by lifting one end of the bed, the sliding wheels 25 enable the bed to slide, thereby facilitating the movement of the bed.

[0027] The described embodiments are only the alternate embodiments of the present disclosure, which do not limit the concept and scope of the present disclosure. Without departing from the design concept of the present disclosure, the various changes, equivalent substitutions, and improvements made to the technical solution of the present disclosure by those of ordinary skill in art fall within the scope of the present disclosure.
