Description

TECHNICAL FIELD

[0001] The present application relates to the field of household, in particular to a height adjusting mechanism of a guard bar and a baby crib. BACKGROUND

[0002] The baby crib is used for the sleep and activity of the baby, and can provide safety protection for the baby. The baby crib facilitates the nursing of the baby by the relevant caregivers. In order to avoid the baby from falling off the baby crib by climbing or moving on his own, a certain height of the guard bar is usually arranged around the baby crib, which can effectively limit the activity range of the baby and avoid the baby from falling. However, due to the obstruction of the guard bar, the relevant caregivers cannot observe the state of the baby in the crib when they are lying or sitting, and cannot directly nurse the baby. The caregivers need to get up until above the height of the guard bar when observing or nursing the baby, which will increase the nursing pressure of the caregivers and affect the normal rest of the caregivers.

[0003] In the related art, the single-side guard bar of the baby crib is usually set as an adjustable guard bar, that is, the height of the single-side guard bar can be at different height positions according to actual needs. When the caregivers rest, the adjustable guard bar is adjusted to a low position, so that the caregivers can directly observe and nurse the baby. When the caregivers are away from the baby crib, the adjustable guard bar is adjusted to a high position to prevent the baby from falling off the bed when no one is watching the baby. Specifically, a plurality of mounting holes are arranged on the two support rods of the single side of the baby crib in the height direction, and when the height needs to be adjusted, the guard bar is first removed from the mounting hole of the original height, and then the mounting hole of the target height is re-inserted to realize the height adjustment of the guard bar. However, this height adjustment method increases the assembly and disassembly process of the guard bar, and the overall operation is complex and low in efficiency. SUMMARY

[0055] Compared with the prior art, the beneficial effects of the embodiments of the present application are:

[0056] In the technical scheme of the present application, when the arrangement height of the blocking rod needs to be adjusted, the driving part is only needed to be pressed tightly in the vertical direction, i.e., the second abutting inclined surface of the driving part can abut against the first abutting inclined surface of the driven part, so that the driven part moves in the direction away from the height adjusting seat to drive the latch to be out of the first positioning hole or the second positioning hole. The elastic part is compressed to generate an elastic force moving towards the height adjusting seat. After the blocking rod reaches the target position, the driving part is released, and the elastic part can push the driven part to move towards the height adjusting seat to drive the latch to penetrate into the first positioning hole or the second positioning hole, thereby completing the locking and height adjustment of the blocking rod. Compared with the height adjustment mode of the prior art, i.e., disassembling and assembling the blocking rod to penetrate into the mounting hole at the target height position. The height adjustment operation of the blocking rod height adjusting mechanism of the present scheme is convenient and fast, and the process of disassembling and assembling the blocking rod can be omitted, thereby improving the height adjustment efficiency of the blocking rod. Further, the latch of the movable part can penetrate into the first positioning hole or the second positioning hole at different height positions, i.e., the blocking rod can be fixedly connected with the height adjusting seat through the movable part. Compared with the structure that the slidingly adjusted blocking rod is fixed with the support rod by relying on the friction force, the present scheme uses the mode that the latch penetrates into the first positioning hole or the second positioning hole, which is more secure, and can improve the stability of the connection between the blocking rod and the support rod, thereby guaranteeing the structural strength of the baby crib.

Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, "and / or", "and / or", or "and / or" appearing throughout the text means that the three parallel schemes include A scheme, or B scheme, or A and B schemes are satisfied at the same time. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0106] In the related art, the single-side guard bar of the baby crib is usually set as an adjustable guard bar, that is, the height of the single-side guard bar can be at different height positions according to actual needs. When the caregiver rests, the adjustable guard bar is adjusted to a low position, so that the caregiver can directly observe and care for the baby. When the caregiver is away from the baby crib, the adjustable guard bar is adjusted to a high position to prevent the baby from falling out of the bed when no one is watching the baby. Specifically, a plurality of mounting holes are arranged on the two support rods on the single side of the baby crib in the height direction, and when the height needs to be adjusted, the guard bar is first removed from the mounting hole at the original height, and then the mounting hole at the target height is rethreaded to achieve the height adjustment of the guard bar. However, this height adjustment method increases the assembly and disassembly process of the guard bar, and the overall operation is complex and inefficient.

[0107] In view of this, the embodiment of the present application proposes a guard bar height adjusting mechanism 10 for adjusting the arrangement height of the guard bar 202 in the baby crib 1. In order to facilitate the understanding and description of the arrangement direction of the support bar 201 and the guard bar 202 in the baby crib 1, first of all, the direction from the bottom of the baby crib 1 to the top is defined as the vertical direction Z, and secondly, the direction from the head of the baby crib 1 to the tail is defined as the horizontal direction X, and the description of the horizontal direction X and the vertical direction Z below is the same as the meaning here. The baby crib 1 comprises the support bar 201 arranged along the vertical direction Z and the guard bar 202 arranged along the horizontal direction X. The support bar 201 arranged along the vertical direction Z is the main load-bearing component of the baby crib 1, and is used to connect and support the bed plate 204. The embodiment of the present application takes four support bars 201 as an example. The guard bar 202 is connected with the support bar 201 and jointly defines the activity range of the baby, preventing the baby from falling off the bed by climbing. The embodiment of the present application takes two guard bars 202 as an example. It should be noted that the height of only one guard bar 202 on one side of the baby crib 1 can be adjusted, or the height of two guard bars 202 on both sides of the baby crib 1 can be adjusted. The embodiment of the present application takes adjusting the height of one guard bar 202 on one side of the baby crib 1 as an example, which is determined according to the actual situation.

[0108] It can be understood that the baby crib 1 also comprises the bed plate 204 for carrying the baby. In some embodiments, the guard bar 202, the bed plate 204 and the support bar 201 can be connected by bed cloth, and the bed plate 204 and the surrounding bed cloth jointly define the activity cavity of the baby. The bed cloth can prevent the baby from being injured by colliding with the support bar 201 or the guard bar 202, thereby ensuring the safety of the baby. In other embodiments, the guard bar 202, the bed plate 204 and the support bar 201 can be connected by a flexible mesh, and the bed plate 204 and the surrounding bed cloth jointly define the activity cavity of the baby. The flexible mesh can increase the ventilation performance of the bed body and facilitate the caregiver to observe the state of the baby from multiple angles. It should be noted that the opening of the activity cavity faces upwards and is used for the baby to enter and exit the activity cavity.

[0109] The guard bar height adjusting mechanism 10 of the embodiment of the present application will be introduced below with reference to Figures 1 to 21 . Specifically, the guard bar height adjusting mechanism 10 comprises a height adjusting seat 100, a movable part 200 and a locking mechanism 300.

[0110] With reference to Figure 4 , Figure 5 and Figure 7 , the height adjusting seat 100 is the adjusting base body of the guard bar height adjusting mechanism 10, and is used to be fixedly connected with the support bar 201. Specifically, the height adjusting seat 100 is sleeved on the upper end of the support bar 201. The height adjusting seat 100 is provided with a sliding groove 130 arranged along the vertical direction Z. With reference to Figure 4 , Figure 7 and Figure 9, the sliding groove 130 is used for the movable part 200 to slide to adjust the vertical position of the blocking rod 202 relative to the support rod 201. The height adjustment seat 100 is also provided with a first positioning hole 112 and a second positioning hole 122, the first positioning hole 112 is arranged above the second positioning hole 122, referring to Figure 7 . It should be noted that when the caregiver is away from the baby bed 1 and no one takes care of the baby, the first positioning hole 112 can fix the blocking rod 202 at a designated position at a high position, thereby effectively preventing the baby from falling, referring to Figure 2 . The second positioning hole 122 can fix the blocking rod 202 at a designated position at a low position, which is convenient for the caregiver to care for the baby when lying or sitting, and reduces the care pressure of the caregiver, referring to Figure 1 and Figure 3 . The first positioning hole 112 and the second positioning hole 122 can be circular, oval, square, strip-shaped, etc., and the embodiment of the present application takes a strip-shaped positioning hole as an example. The strip-shaped positioning hole can provide redundant space for the to-be-inserted part, so that the to-be-inserted part can be inserted into the first positioning hole 112 and the second positioning hole 122, and the stable fixation of the blocking rod 202 is realized.

[0111] The movable part 200 is used to adjust the vertical position of the blocking rod 202 relative to the support rod 201. In some embodiments, both ends of the blocking rod 202 can be connected to the movable part 200, which is convenient for the blocking rod 202 to stably switch the position along the vertical direction, referring to Figures 1 to 3 . In other embodiments, one end of the blocking rod 202 is connected to the movable part 200, and the other end can be connected to other sliding structures. The specific setting can be determined according to the actual situation, and some embodiments of the present application take the example that the blocking rod 202 is provided with the movable part 200 at both ends. The movable part 200 includes a sliding block 230 which is in sliding connection with the sliding groove 130 of the height adjustment seat 100, referring to Figures 12 to 14 . The sliding block 230 is inserted and fitted with the sliding groove 130 and can slide up and down in the sliding groove 130, that is, the sliding block 230 can slide along the vertical direction Z in the sliding groove 130 to adjust the vertical position of the blocking rod 202 relative to the support rod 201.

[0112] The locking mechanism 300 is connected with the movable part 200, which is used to lock the blocking rod 202 at a designated position and make the blocking rod 202 normally switch the position, referring to Figure 6 、 Figure 10 and Figure 11The locking mechanism 300 comprises a resilient portion 320, a driven portion 310, a latch 330, and a driving portion 340. The driven portion 310 is in sliding connection with the movable portion 200 and is capable of sliding along the lateral direction X relative to the movable portion 200. The end of the driven portion 310 away from the height-adjustable seat 100 is connected with the resilient portion 320, and the end of the driven portion 310 close to the height-adjustable seat 100 is connected with the latch 330, i.e., the resilient portion 320 and the latch 330 are arranged on the two sides of the driven portion 310 opposite to each other. Specifically, the resilient portion 320 and the latch 330 are arranged opposite to each other along the lateral direction X, and the driven portion 310 is in sliding connection with the driving portion 340, and the driving portion 340 is arranged below the driven portion 310, and the driving portion 340 is capable of driving the driven portion 310 to slide along the lateral direction X relative to the movable portion 200, and the driving portion 340 is capable of driving the latch 330 to be inserted into or withdrawn from the first positioning hole 112 or the second positioning hole 122. Figure 6 .

[0113] The latch 330 is operable to be inserted into the first positioning hole 112 or the second positioning hole 122. Specifically, the latch 330 is configured to be driven by the driving portion 340 to extend into or withdraw from the first positioning hole 112 or the second positioning hole 122. For the convenience of description and understanding, it is defined that the latch 330 has a first positioning position and a second positioning position. When the latch 330 is in the first positioning position, the latch 330 can be inserted into the first positioning hole 112 or the second positioning hole 122 to lock the driven portion 310 with the height-adjustable seat 100, so as to fix the stop lever 202 at different height positions to adapt to different application scenarios, and when the latch 330 is in the second positioning position, the latch 330 can release the lock of the driven portion 310 with the height-adjustable seat 100 to facilitate the switching of the stop lever 202 between different height positions. Figures 1 to 3 The latch 330. When the latch 330 is in the second positioning position, the latch 330 can release the lock of the driven portion 310 with the height-adjustable seat 100 to facilitate the switching of the stop lever 202 between different height positions.

[0114] The driven portion 310 comprises a first abutting inclined surface 311, and the driving portion 340 is arranged below the driven portion 310, and Figure 16 and Figure 17 The driving portion 340 comprises a second abutting inclined surface 341, and Figure 18 The second abutting inclined surface 341 abuts against the first abutting inclined surface 311, so that the driven portion 310 can be driven by the driving portion 340 to slide along the lateral direction X relative to the movable portion 200. It should be noted that in the present scheme, the first abutting inclined surface 311 of the driven portion 310 is provided with two. Correspondingly, the second abutting inclined surface 341 of the driving portion 340 is provided with two. Compared with a single abutting inclined surface, the double abutting inclined surfaces can improve the stability of the movement between the driven portion 310 and the driving portion 340, reduce the shaking of the driven portion 310 and the driving portion 340 in the shell 240, and reduce the transmission noise.

[0115] It can be understood that when the latch 330 is in the first position, i.e., the blocking rod 202 is locked, the driving part 340 is configured to obtain an upward driving force and can move upward relative to the driven part 310. Specifically, by pressing the driving part 340 in the vertical direction Z, the second abutting slope 341 of the driving part 340 can push the first abutting slope 311 of the driven part 310 to slide in a direction away from the height adjustment base 100. Since the end of the driven part 310 close to the height adjustment base 100 is connected to the latch 330, the latch 330 can be released from the first positioning hole 112 or the second positioning hole 122, so that the latch 330 moves from the first position to the second position. Since the end of the driven part 310 away from the height adjustment base 100 is connected to the elastic part 320, the elastic part 320 can be compressed. When the latch 330 is in the second position, the elastic part 320 has an elastic force to push the driven part 310 to move in a direction close to the height adjustment base 100, so as to push the latch 330 from the second position to the first position.

[0116] In the technical solution of the present application, when the arrangement height of the blocking rod 202 needs to be adjusted, the driving part 340 is only needed to be pressed in the vertical direction Z, i.e., the second abutting slope 341 of the driving part 340 can abut against the first abutting slope 311 of the driven part 310, so as to drive the driven part 310 to move in a direction away from the height adjustment base 100, so as to drive the latch 330 to be released from the first positioning hole 112 or the second positioning hole 122. The elastic part 320 is compressed to generate an elastic force to move toward the height adjustment base 100. After the blocking rod 202 reaches the target position, the driving part 340 is released, the elastic part 320 can push the driven part 310 to move toward the height adjustment base 100, so as to drive the latch 330 to penetrate into the first positioning hole 112 or the second positioning hole 122, to complete the locking of the blocking rod 202 and the height adjustment operation. Compared with the height adjustment mode of the prior art, i.e., disassembling the blocking rod to penetrate into the mounting hole of the target height position. The height adjustment operation of the blocking rod height adjustment mechanism 10 of the present application is convenient and fast, and the process of disassembling the blocking rod 202 can be omitted, and the height adjustment efficiency of the blocking rod 202 is improved. Further, the latch 330 of the movable part 200 can penetrate into the first positioning hole 112 or the second positioning hole 122 at different height positions, i.e., the blocking rod 202 can be fixedly connected with the height adjustment base 100 through the movable part 200. Compared with the structure that the sliding adjustment blocking rod 202 is fixed with the support rod 201 by relying on the friction force, the present application uses the way that the latch 330 penetrates into the first positioning hole 112 or the second positioning hole 122, which is more firm, can improve the stability of the connection between the blocking rod 202 and the support rod 201, and ensure the structural strength of the crib 1.

[0117] In some embodiments, the end of the driven part 310 away from the height adjustment base 100 is provided with a first accommodating groove 312, and the first accommodating groove 312 is used to accommodate the elastic part 320. Referring to Figure 10 ,Figure 11 and Figure 15 The first accommodating groove 312 can have a circular, square, polygonal or other cross-sectional shape along the vertical direction Z. In the embodiments, the first accommodating groove 312 has a square cross-sectional shape. It should be noted that the elastic part 320 can be a spring. One end of the spring is connected to the movable part 200. Specifically, the end of the connecting structure 220 close to the height adjustment seat 100 can be provided with a flange 223, which will be described below with reference to Figure 11 The flange 223 can be integrally connected to the connecting structure 220, and one end of the spring can be sleeved on the flange 223, thereby improving the stability of the connection between the spring and the connecting structure 220. The other end of the spring extends into the first accommodating groove 312 and abuts against the groove wall of the first accommodating groove 312. It can be understood that the groove wall here refers to the end wall of the first accommodating groove 312 close to the second accommodating groove 313. The abutment of the spring against the groove wall can transmit the elastic force to the driven part 310, thereby facilitating the movement of the driven part 310 in the direction close to the height adjustment seat 100, so that the bolt 330 penetrates into the first positioning hole 112 or the second positioning hole 122. The first accommodating groove 312 can stably hold the spring, preventing the spring from tilting and losing elastic force when being compressed or released. Compared with the elastic sheet, the driving stroke of the spring in the present solution is longer, which ensures that the bolt 330 has an effective locking length and improves the stability of the blocking rod 202 at different heights.

[0118] The end of the driven part 310 facing the height adjustment seat 100 is provided with a second accommodating groove 313 for accommodating the bolt 330, which will be described below with reference to Figure 10 , Figure 11 , Figure 16 and Figure 17 One end of the bolt 330 is detachably accommodated in the second accommodating groove 313, and the other end extends out of the second accommodating groove 313. Compared with the mode in which the bolt 330 is integrally formed with the driven part 310 or fixedly connected to the driven part 310, the installation of the bolt 330 in the present solution is more convenient, and different specifications and sizes of the bolt 330 can be replaced to meet different locking force requirements.

[0119] In some embodiments, the second accommodating groove 313 extends through the driven part 310 in a direction away from the driving part 340, thereby facilitating the direct disassembly and assembly of the bolt 330. To facilitate the understanding and description of the structure of the second accommodating groove 313, the direction in which the elastic part 320 points to the height adjustment seat 100 is defined as the first direction A. It should be noted that when the bolt 330 is in the first positioning position or the second positioning position, the first direction A is parallel to the transverse direction X. The second accommodating groove 313 includes a first portion 3131 and a second portion 3132 that are relatively distributed along the first direction A. The first portion 3131 is close to the first accommodating groove 312, and the second portion 3132 is away from the first accommodating groove 312. The side wall of the first portion 3131 facing the first accommodating groove 312 is in communication with the second portion 3132, which will be described below with reference to Figure 16 and Figure 17For the convenience of understanding and describing the structure and relative size of the first part 3131 and the second part 3132 in the second accommodating groove 313, a plane perpendicular to the first direction A is defined as a first projection plane. The first part 3131 forms a first orthographic projection on the first projection plane, and the second part 3132 forms a second orthographic projection on the first projection plane. The area of the first orthographic projection is greater than the area of the second orthographic projection, that is, the spatial volume of the first part 3131 along the direction perpendicular to the first direction A is greater than the spatial volume of the second part 3132 along the direction perpendicular to the first direction A. Moreover, the first orthographic projection covers the second orthographic projection, that is, the second part 3132 is in the first part 3131 when viewed in the direction facing the first projection plane.

[0120] The latch 330 includes a plug portion 331 and a limiting portion 332 connected to each other. Referring to Figure 15 The limiting portion 332 is clamped in the first part 3131 and abuts against the side wall of the first part 3131 facing the first accommodating groove 312. The plug portion 331 is partially accommodated in the second part 3132 and partially extends out of the second part 3132. By arranging the second accommodating groove 313 as the first part 3131 and the second part 3132, the displacement of the latch 330 along the first direction A can be limited, and the deflection of the latch 330 during insertion can be avoided, improving the precision of insertion. Further, the appropriate specification of the latch 330 can be selected according to the specific size of the second accommodating groove 313, improving the tightness of the connection between the latch 330 and the second accommodating groove 313, that is, the vibration of the latch 330 during insertion can be weakened, the insertion noise of the latch 330 can be reduced, and the user experience can be improved.

[0121] In some embodiments, referring to Figure 5 and Figure 6 The movable part 200 includes a shell 240 and a movable block 210 connected to the locking mechanism 300. The shell 240 includes a first shell 241 and a second shell 242 opposite to the first shell 241, the upper end of the first shell 241 is connected to the upper end of the second shell 242, and a gap 243 is defined between the first shell 241 and the second shell 242, referring to Figure 19 and Figure 20 The movable block 210 is arranged in the gap 243. Arranging the shell 240 can shield the internal structure of the movable part 200, improving the overall aesthetics of the product.

[0122] The end of the movable block 210 away from the height adjustment seat 100 is provided with a connecting structure 220 for connecting the stop rod 202, so that the movable block 210 can drive the stop rod 202 to switch the height position. The stop rod 202 includes a first end 2021 and a second end 2022 arranged opposite to each other along the extension direction thereof, referring to Figure 3The gap 243 between the first housing 241 and the second housing 242 is adapted to the first end 2021 and the connecting structure 220 to be hinged, so that the second end 2022 of the blocking rod 202 can be rotated towards the height adjustment seat 100. It should be noted that the second end 2022 of the blocking rod 202 can also be connected to the hinge structure. That is, the folding of the baby crib 1 can be realized, which is convenient for the storage and transportation of the baby crib 1.

[0123] The movable block 210 is connected to the sliding block 230 at one end close to the height adjustment seat 100, and the sliding block 230 extends out of the gap 243 and cooperates with the sliding groove 130. That is, during the sliding of the sliding block 230 relative to the sliding groove 130 of the height adjustment seat 100, the sliding block 230 can drive the movable block 210 to slide, thereby realizing the height adjustment of the blocking rod 202.

[0124] The driven part 310 is slidingly connected to the movable block 210, and the driven part 310 can slide relative to the movable block 210 in a horizontal direction close to or away from the height adjustment seat 100. The driving part 340 is slidingly connected to the movable block 210, and the driving part 340 can slide relative to the movable block 210 in the vertical direction Z. That is, the driven part 310 can convert the pushing force of the driving part 340 in the vertical direction Z into the sliding force of the driven part 310 in the horizontal direction, thereby driving the latch 330 to penetrate into or out of the first positioning hole 112 or the second positioning hole 122.

[0125] In some embodiments, referring to Figure 16 and Figure 17 , the end of the driven part 310 away from the driving part 340 is provided with a first protrusion 314 and a second protrusion 315, and the first protrusion 314 and the second protrusion 315 are oppositely and spacedly arranged in the direction from the first accommodating groove 312 to the second accommodating groove 313. The first protrusion 314 and the first protrusion 314 can abut against the movable block 210, that is, when the second abutting slope 341 of the driving part 340 presses the first abutting slope 311 of the driven part 310, the driven part 310 can slide on the movable block 210. By additionally providing the first protrusion 23211 and the second protrusion 23211, the abutting area of the driven part 310 and the movable block 210 can be reduced, the friction between the driven part 310 and the movable block 210 can be reduced, and the driven part 310 can slide smoothly and smoothly. And when the movable block 210 is stressed and deformed, the driven part 310 can still slide by abutting against the sliding block through the first protrusion 23211 and the second protrusion 23211, preventing the deformed movable block 210 from being stuck, and ensuring the stability of the movement of the driven part 310.

[0126] It should be noted that the first protrusion 314 can be arranged near one end of the first accommodating groove 312. The second protrusion 315 can be arranged near one end of the second accommodating groove 313, or can be arranged at the second accommodating groove 313. At the second accommodating groove 313, the second protrusion 315 can be divided into two parts by the second accommodating groove 313. The specific arrangement can be determined according to actual conditions.

[0127] It can be understood that the first protrusion 314 can be arranged in a direction perpendicular to the first accommodating groove 312 to the second accommodating groove 313, or can be arranged in a direction intersecting the first accommodating groove 312 to the second accommodating groove 313. The first protrusion 314 can be arranged in different extension lengths according to actual needs.

[0128] Similarly, the second protrusion 315 can be arranged in a direction perpendicular to the first accommodating groove 312 to the second accommodating groove 313, or can be arranged in a direction intersecting the first accommodating groove 312 to the second accommodating groove 313. The second protrusion 315 can be arranged in different extension lengths according to actual needs.

[0129] In some embodiments, with reference to Figures 10 to 12 The balancing part 211 is arranged near one end of the height adjusting seat 100, and can disperse the stress generated by the blocking rod 202 during folding, thereby ensuring the structural stability of the movable part 200, reducing deformation of the movable part 200, and preventing it from breaking. The balancing part 211 includes a third end 2111 and a fourth end 2112 arranged vertically opposite to each other in a direction perpendicular to the first accommodating groove 312 to the second accommodating groove 313. It should be noted that the vertical direction is taken as a reference in the arrangement direction of the crib 1 in the working state.

[0130] The third end 2111 is provided with a balancing groove 21111, and the slot of the balancing groove 21111 faces away from the driving part 340. Arranging the balancing groove 21111 can increase the structural strength of the movable block 210 and reduce the deformation of the movable block 210. The specific arrangement of the balancing groove 21111 can be determined according to actual conditions. The fourth end 2112 is provided with a first clamping block 21121 and a second clamping block 21122 arranged horizontally opposite to each other in the direction of the first accommodating groove 312 to the second accommodating groove 313. It should be noted that the first clamping block 21121 can extend towards the height adjusting seat 100, and the second clamping block 21122 can extend away from the height adjusting seat 100. The first clamping block 21121 is used to clamp the first neck part 342 of the driving part 340, and the second clamping block 21122 is used to clamp the second neck part 343 of the driving part 340. By arranging the first clamping block 21121 and the second clamping block 21122, the structural strength of the movable block 210 can be further increased, and the driving part 340 can be limited, so that the driving part 340 can be stably connected with the movable block 210, and the driving part 340 can be prevented from falling off.

[0131] In some embodiments, the connecting structure 220 comprises a first clamping plate 221 and a second clamping plate 222, as shown in Figure 10 and Figure 12 . The first clamping plate 221 and the second clamping plate 222 are oppositely arranged with a gap 243 therebetween, and the upper ends of the first clamping plate 221 and the second clamping plate 222 are connected. The first clamping plate 221 is connected to the first shell 241, and the second clamping plate 222 is connected to the second shell 242. The first clamping plate 221 is provided with a first hinge hole 2211, and the second clamping plate 222 is provided with a second hinge hole 2221, the hole axes of the first hinge hole 2211 and the second hinge hole 2221 coincide, and the first hinge hole 2211 and the second hinge hole 2221 are adapted to be hinged with the stop rod 202 extending into the gap 243 between the first clamping plate 221 and the second clamping plate 222. The arrangement of the first clamping plate 221 and the second clamping plate 222 can limit the rotation direction of the stop rod 202, avoid the inclination of the stop rod 202, and realize the smooth coagulation of the crib 1.

[0132] Referring to Figure 10 and Figure 12 , the first clamping plate 221 has a first side edge 2212 away from the sliding block 230 and a second side edge 2213 close to the sliding block 230. The second side edge 2213 is arranged along the vertical direction Z. The first side edge 2212 comprises a first section 22121 and a second section 22122, the lower end of the first section 22121 is connected to the upper end of the second section 22122, the first section 22121 is parallel to the second side edge 2213, and the first hinge hole 2211 is arranged between the first section 22121 and the second side edge 2213. Along the direction from top to bottom, the distance between the second section 22122 and the second side edge 2213 gradually decreases.

[0133] Referring to Figure 10 and Figure 12 , the second clamping plate 222 has a third side edge 2222 away from the sliding block 230 and a fourth side edge 2223 close to the sliding block 230. The fourth side edge 2223 is arranged along the vertical direction Z. The third side edge 2222 comprises a third section 22221 and a fourth section 22222, the lower end of the third section 22221 is connected to the upper end of the fourth section 22222, the third section 22221 is parallel to the fourth side edge 2223, and the second hinge hole 2221 is arranged between the third section 22221 and the fourth side edge 2223. Along the direction from top to bottom, the distance between the fourth section 22222 and the fourth side edge 2223 gradually decreases.

[0134] The distance between the first section 22121 and the second side edge 2213 is D1, the length of the first section 22121 along the vertical direction Z is D2, and the length of the second section 22122 is D3, wherein D1=D2=D3. The distance between the third section 22221 and the fourth side edge 2223 is D4, the length of the third section 22221 along the vertical direction Z is D5, and the length of the fourth section 22222 is D6, wherein D4=D5=D6. The above arrangement of the side edges can facilitate the engagement of the crib 1 with the blocking rod 202 when the crib 1 is folded, thereby preventing the crib 1 from being spread out after being folded.

[0135] In some embodiments, the first shell 241 is adapted to be arranged on the inner side of the crib 1, and the second shell 242 is adapted to be arranged on the outer side of the crib 1. For the purpose of understanding and description, the structure and relative size of the first shell 241 and the second shell 242 are described. A plane perpendicular to the width direction of the gap 243 is defined as a second projection plane. The first shell 241 forms a third orthographic projection on the second projection plane, and the second shell 242 forms a fourth orthographic projection on the second projection plane. The area of the third orthographic projection is greater than the area of the fourth orthographic projection, that is, the volume of the first shell 241 is greater than the volume of the second shell 242 when viewed in the direction facing the second projection plane. Moreover, the third orthographic projection covers the fourth orthographic projection, that is, the second shell 242 is located within the coverage area of the first shell 241 when viewed in the direction facing the second projection plane. The dimension of the first shell 241 along the vertical direction Z is greater than the dimension of the second shell 242 along the vertical direction Z. The lower end of the drive portion 340 protrudes out of the gap 243, and the drive portion 340 forms a fifth orthographic projection on the second projection plane, which is located within the third orthographic projection. The first shell 241 protrudes downward, which can prevent the bed cloth from entering the shell when the crib 1 is folded, thereby ensuring the normal folding of the crib 1.

[0136] In some embodiments, referring to Figure 13 , one end of the movable block 210 close to the sliding block 230 is provided with a connecting groove 212 for connecting the shell 240. The connecting groove 212 extends along the vertical direction, and the groove opening of the connecting groove 212 faces the outer side of the crib 1.

[0137] Referring to Figure 21 , the side of the second shell 242 facing the first shell 241 is provided with a connecting block 2421. The connecting block 2421 is arranged in a matching manner with the connecting groove 212, and the connecting block 2421 can slide through the connecting groove 212, that is, the sliding assembly connection between the shell 240 and the sliding block can be achieved, thereby facilitating the disassembly and assembly of the shell 240. Moreover, by arranging the connecting groove 212, the structural strength of the movable block 210 can be further enhanced, the deformation of the movable block 210 can be reduced, and the structural stability of the crib 1 can be ensured.

[0138] In some embodiments, the groove opening of the sliding groove 130 is provided with a first engagement portion 131 and a second engagement portion 132, referring to Figure 9The first clamping portion 131 is spaced apart from and oppositely arranged to the second clamping portion 132. The first clamping portion 131 is located at one side of the sliding groove 130 along the width direction, and the second clamping portion 132 is arranged at the other side of the sliding groove 130 along the width direction. Both the first clamping portion 131 and the second clamping portion 132 extend along the vertical direction Z. It can be understood that the specific extension length of the first clamping portion 131 and the second clamping portion 132 depends on the actual needs.

[0139] The sliding block 230 includes a connecting portion 231 and a clamping portion 232. Referring to Figure 14 It can be understood that the connecting portion 231 and the clamping portion 232 can be integrally formed, or the connecting portion 231 and the clamping portion 232 can be separately formed and then connected. One side of the connecting portion 231 is connected to the movable block 210, and the other side of the connecting portion 231 is connected to the clamping portion 232. It should be noted that the sliding block 230 is arranged at the side of the connecting portion 231 close to the height adjusting seat 100. The connecting portion 231 is arranged in the gap 243 between the first clamping portion 131 and the second clamping portion 132, and the clamping portion 232 is arranged at the side of the first clamping portion 131 and the second clamping portion 132 away from the movable block 210.
