The bed frame 200 includes a head rail 210, a foot rail 220, and a pair of side rails 230 located on the left and right sides. The bed board 100 has a head end and a foot end located at two different ends of its length direction, and the bed board 100 has at least a horizontal position in which the head end and the foot end are flush with each other, and a tilted position in which the head end and the foot end are one high and one low.

[0049] The bed board 100 has an adjustable end portion which is mounted on the bed frame 200 and can be adjusted in height. The adjustable end portion can be the head end and / or the foot end of the bed, and the adjustable end portion is connected to the bed frame 200 through the adjustment mechanism 300 to be at different height positions. The adjustment mechanism 300 includes an adjustment track 1 which is extended in the up-down direction and arranged on the bed frame 200 and has a plurality of height levels, and a limit assembly for positioning the adjustable end portion of the bed board 200 at one of the height levels.

[0050] In this embodiment, the head end and the foot end of the bed are both adjustable ends, and both are connected to the bed frame 200 through an adjusting mechanism 300, so that the bed board 100 can not only adjust the height of the bed board 100, but also can be adjusted to make the head end and the foot end of the bed present a high and low tilt state, so that the head of the baby lying on the bed board 200 is higher than the feet to prevent milk spillage.

[0051] See also Figures 1 to 9 As shown, the head end of the bed is connected to the head rail 210 through two sets of adjustment mechanisms 300, and the tail end of the bed is connected to the tail rail 220 through two sets of adjustment mechanisms 300, and the adjustment track 1 is set on the head rail 210 and the tail rail 220.

[0052] The adjustment track 1 includes a guide groove 11 arranged on the bed frame 200 along the up-down direction, and a plurality of gear grooves 12 arranged at intervals along the length extension direction of the guide groove 11, and each gear groove 12 is connected to the guide groove 11. The limit assembly includes a gear pin 2 connected to the bed board 100 and capable of relative movement along the length direction of the bed board 100, and the gear pin 2 can be inserted into the gear groove 12 in a relatively slidable manner along the extension direction of the gear groove 12, and the limit assembly also includes an elastic member 3 for driving the gear pin 2 to slide toward the gear groove 12.

[0053] In this embodiment, a connecting member 4 is fixedly provided on the adjustment end of the bed board 100, and the connecting member 4 extends outwardly along the length extension direction of the bed board 100 and can be slidably arranged up and down along the guide groove 11, and the shift pin 2 can be relatively slidably arranged on the connecting member 4 along the length extension direction of the connecting member 4. Here, the connecting member 4 includes a connecting rod portion 41, and a limiting head portion 42 arranged at one end of the connecting rod portion 41, and the outer diameter of the limiting head portion 42 is larger than the outer diameter of the connecting rod portion 41, and the other end of the connecting rod portion 41 is fixedly provided on the bed board 100. The shift pin 2 is slidably sleeved on the connecting rod portion 41 along the length extension direction of the connecting member 4, and the elastic member 3 is a spring sleeved on the connecting rod portion 41 and located between the shift pin 2 and the limiting head portion 42.

[0054] In this embodiment, three gear slots 12 are provided on each adjustment mechanism 300, so that the head end and the foot end of the bed have three height adjustment gears. When the head end and the foot end of the bed are flush with each other, the bed board 200 is in a horizontal position and has three height gears of high, medium and low, respectively. Figure 2 , Figure 8 , Fig. 9 shown.

[0055] See also Figures 4 to 7 As shown, the shift pins 2 on the head end and the tail end of the bed can be inserted into the shift slots 12 at different heights in a coordinated manner, so that the bed board 100 is in an inclined position. When the shift pin 2 is pulled outward, the shift pin 2 compresses the spring 3 and withdraws from the shift slot 12. At this time, the shift pin 2 is pulled up to make the end of the bed board 100 move up and down. When the next shift slot 12 is reached, the shift pin 2 is released. Under the action of the spring 3, the shift pin 2 enters the corresponding shift slot 12, so that the end of the bed board 100 is fixedly connected to the bed frame 200 again.

[0056] Example 2

[0057] See also Figures 10 to 14 As shown, the main difference between this embodiment and embodiment 1 is that the setting mode of the adjustment mechanism 300 is different. Specifically, in this embodiment, the adjustment track 1 includes a slide groove 13 arranged on the bed frame 200 along the up-down direction, and a plurality of limit grooves 14 arranged at intervals along the length extension direction of the slide groove 13, and the limit grooves 14 are connected with the slide groove 13. The limit assembly includes a limit pin 5 that can be relatively moved along the width direction of the bed board 100 and is arranged on the adjustment end. The limit pin 5 can be relatively slidably inserted into the slide groove 13 along the length extension direction of the slide groove 13, and can be inserted into the limit groove 14 when moving relative to the bed board 100, so that the adjustment end of the bed board 100 is fixed relative to the bed frame 200.

[0058] The limiting assembly also includes an operating button 6 fixedly connected to the limiting pin 5 for driving the limiting pin 5 to move relative to the bed board 200, and an elastic member 7 for driving the limiting pin 5 to move relative to the bed board 100 and enter the limiting groove 14 from the slide groove 13.

[0059] In this embodiment, the head end of the bed is connected to the head rail 210 through two sets of adjustment mechanisms 300, and the tail end of the bed is connected to the tail rail 220 through two sets of adjustment mechanisms 300, and the adjustment track 1 is set on the head rail 210 and the tail rail 220. That is, each adjustment end (head end / tail end) is connected to the bed frame 200 through two sets of limit components, and accordingly, the slide groove 13 and the limit groove 14 are also provided with two sets, wherein the two sets of limit pins 5 slide in opposite directions when entering the limit groove 14 from the slide groove 13. When the user adjusts the height of the bed board 100, the two operating buttons 6 on the same adjustment end are operated with both hands to make the two move toward each other, so that the two sets of limit pins 5 can be withdrawn from the limit grooves 14 on both sides at the same time to change the height gear again.

[0060] Example 3

[0061] See also Figures 15 to 19 As shown, the difference between this embodiment and embodiment 1 is mainly that:

[0062] 1. In this embodiment, one end of the bed board 100 is rotatably connected to one end of the bed frame 200 through a rotating shaft 101, and the other end of the bed board 100 is connected to the other end of the bed frame 200 through an adjusting mechanism 300, so that the angle of the bed board 100 can be adjusted and can be switched between a horizontal position and an inclined position. The rotating shaft 101 can be set at the head end of the bed, and the adjusting mechanism 300 can be set at the tail end of the bed, and the bed board 100 can be switched from a horizontal position to an inclined position by lowering the tail end of the bed; the rotating shaft 101 can also be set at the tail end of the bed, and the adjusting mechanism 300 can be set at the head end of the bed, and the bed board 100 can be switched from a horizontal position to an inclined position by raising the head end of the bed. The former is adopted in this embodiment.

[0063] 2. In this embodiment, the arrangement of the adjustment mechanism 300 is different from that in Embodiment 1:

[0064] Specifically, in this embodiment, there are two adjustment mechanisms 300, which are symmetrically arranged on the left and right sides of the crib.

[0065] In the adjustment mechanism 300, the adjustment track includes a guide slot 310 provided on the bed frame 200 along the up-down direction, and at least two countersunk holes 320 connected to the guide slot 310, and the at least two countersunk holes 320 are arranged along the extension direction of the guide slot 310. In this embodiment, the guide slot 310 is provided on the side fence 230, and the guide slot 310 is arc-shaped.

[0066] The limit assembly includes a slide pin 330 that can be relatively movably connected to the bed plate 100. The slide pin 330 can be slidably connected to the guide groove 310 along the guide groove 310. Specifically, the slide pin 330 is detachably connected to the countersunk hole 320. When the bed plate 100 is in a horizontal position or an inclined position, the slide pin 330 is located in one of the at least two countersunk holes 320. More specifically, as shown in the attached Fig.17 and attached Fig.18 As shown, there are two countersunk holes 320, which are respectively arranged at the upper and lower ends of the guide slide groove 310. The limit assembly also includes a spring for applying force to the slide pin 330 to make it enter the countersunk hole 320.

[0067] The relative movement direction of the sliding pin 330 and the bed board 100 in this embodiment is along the axial direction of the sliding pin 330. The specific connection structure between the sliding pin 330 and the bed board 100 is as follows: Fig.18 and attached Fig.19 , a connecting member 350 is fixedly connected to the bed board 100, and the other end of the connecting member 350 opposite to the end connected to the bed board 100 has a limiting portion 351 protruding radially outward along the connecting member 350. Preferably, the connecting member 350 is a screw, and the limiting portion 351 is the nail cap of the screw. A nut 110 is embedded in the bed board 100, and the screw is connected to the bed board 110 through the nut 110; the sliding pin 330 is slidably connected to the connecting member 350, and the spring in this embodiment is a first spring 340, which is arranged between the sliding pin 330 and the limiting portion 351 and can make the sliding pin 330 enter the counterbore 320. Preferably, the sliding pin 330 has an accommodating cavity 331, one end of the connecting member 350 passes through the accommodating cavity 331 and is connected to the bed board 100, and the limiting portion 351 is slidably located in the accommodating cavity 331, and the first spring 340 is arranged between the limiting portion 351 and the bottom of the accommodating cavity 331. The guide slot 310 includes a first guide portion 311 for the connecting member 350 to slide and a second guide portion 312 for the sliding pin 330 to slide.

[0068] Working principle:

[0069] When the angle of the bed board 100 is adjusted, the sliding pin 330 is pulled outward along the axial direction of the sliding pin 330, and the sliding pin 330 and the connecting member 350 slide relative to each other, that is, the sliding pin 330 and the bed board 100 slide relative to each other, the first spring 340 is compressed, the sliding pin 330 disengages from the countersunk hole 320, and then the sliding pin 330 is pulled upward or downward, and the sliding pin 330 slides upward or downward along the guide slot 310 (the connecting member 350 slides in the first guide portion 311, and the sliding pin 330 slides in the second guide portion 312), so that the bed board 100 rotates upward or downward around the rotating shaft 101. When the sliding pin 330 slides to the position of another countersunk hole 320, the sliding pin 330 is released, and the sliding pin 330 enters the corresponding countersunk hole 320 under the action of the first spring 340, so that the position between the sliding pin 330 and the guide slot 310 is defined again, and the horizontal angle of the bed board 100 is adjusted.

[0070] Example 4

[0071] See also Figure 20 to Figure 24 As shown, the main difference between this embodiment and Embodiment 3 lies in the arrangement positions of the rotating shaft 101 and the adjusting mechanism 300 , and the specific structure of the adjusting mechanism 300 .

[0072] In this embodiment, the rotating shaft 101 is arranged at the end of the bed, and the adjusting mechanism 300 is arranged at the head end of the bed. The bed board 100 is converted from a horizontal position to an inclined position by raising the head end of the bed.

[0073] In this embodiment, the adjustment track includes a guide slot 310, which includes a first guide segment 313 and a second guide segment 314 both arranged along the up-down direction. Specifically, the two are linear and arranged in parallel. The guide slot 310 also includes at least two V-shaped grooves 360 arranged between the first guide segment 313 and the second guide segment 314 at intervals along the up-down direction. The opening of each V-shaped groove 360 ​​faces upward, and the two ends of the V-shaped groove 360 ​​are respectively connected to the first guide segment 313 and the second guide segment 314, so that the first guide segment 313, the second guide segment 314, and the at least two V-shaped grooves 360 form a closed track.

[0074] The limiting assembly includes a sliding pin 330 that can slide along the first guide section 313 or the second guide section 314. When the bed board 100 is in a horizontal position or an inclined position, the sliding pin 330 is located at the bottom of one of the at least two V-grooves 360 (due to the gravity of the bed board 100, the sliding pin 330 is restricted at the bottom of the V-groove 360).

[0075] More specifically, as attached Fig.24As shown, there are two V-shaped grooves 360, which are respectively arranged at the upper and lower ends of the first guide section 313 and the second guide section 314. The first guide section 313, the second guide section 314 and the two V-shaped grooves 360 form a circular groove.

[0076] The relative movement direction of the sliding pin 330 and the bed board 100 in this embodiment is perpendicular to the axial direction of the sliding pin 330, preferably in the left-right direction. The first guide section 313 and the second guide section 314 are arranged along the relative movement direction of the sliding pin 330 and the bed board 100. The specific connection structure between the bed board 100 and the sliding pin 330 is as follows: Fig. 22 and attached Fig.23 As shown, the bed board 100 has a sliding pin seat 370, one end of the sliding pin 330 is connected to a slider 332, the slider 332 is slidably arranged in the sliding pin seat 370, and the sliding pin seat 370 is provided with a slide groove 371 for the sliding pin 330 to slide therein, and the slide groove 371 is arranged along the direction in which the sliding pin 330 moves relative to the bed board 100. The other end of the sliding pin 330 extends out of the slide groove 371 and is slidably connected to the above-mentioned circular groove.

[0077] In this embodiment, springs are provided on both sides of the sliding pin 330 to drive the sliding pin 330 into the V-shaped groove to achieve position limiting. The spring is the second spring 380, and the second springs 380 on both sides are symmetrically arranged to ensure that the sliding pin 330 is in the middle position when not subject to external force. The "two sides" refer to the relative movement direction between the sliding pin 330 and the bed board 100, which are the left and right sides in this embodiment. Specifically, the second spring 380 is arranged in the sliding pin seat 370 and directly applies force to the slider 332. When the sliding pin 330 moves to the V-shaped groove 360 ​​along the first guide section 313 or the second guide section 314, the second spring 380 causes the sliding pin 330 to enter the V-shaped groove 360.

[0078] In a more preferred embodiment, Fig.24 A first stopper 391 is provided above a V-shaped groove 360. Since the bottom end of the first stopper 391 and the bottom of the V-shaped groove 360 ​​are staggered in the vertical direction, as shown in the attached Fig.24 The bottom end of the first limiting head 391 is located on the right side of the bottom of the V-shaped groove 360 ​​in the vertical direction, so that the sliding pin 330 can move upward in the V-shaped groove 360 ​​and leave the V-shaped groove 360 ​​toward the left and enter the first guide section 313; the other V-shaped groove 360 ​​has a second limiting head 392 above it, and the connection between the other V-shaped groove 360 ​​and the second guide section 314 has a notch 393 below it. Since the bottom end of the second limiting head 392 and the bottom of the other V-shaped groove 360 ​​are staggered in the vertical direction, as shown in the attached Fig.24The bottom end of the second limit head 392 is located on the left side of the bottom of the other V-shaped groove 360 ​​in the vertical direction, so that the sliding pin 330 can move toward the right and leave the other V-shaped groove 360 ​​when moving upward in the other V-shaped groove 360. At this time, when the sliding pin 330 moves downward again, due to the presence of the notch 393, the sliding pin 330 can enter the second guide section 314 without falling back into the other V-shaped groove 360.

[0079] The guide groove 310 and the V-shaped groove 360 ​​in this embodiment are arranged on the end-of-bed fence 220 . Specifically, a guide groove seat 390 is connected to the end-of-bed fence 220 , and the guide groove 310 , the V-shaped groove 360 ​​, the first limit head 391 and the second limit head 392 are all arranged on the guide groove seat 390 .

[0080] Working principle:

[0081] Taking the arrangement positions of the rotating shaft 101 and the adjusting mechanism 300 in this embodiment as an example, when adjusting the angle of the bed board 100, refer to the attached Fig.24 , assuming that the bed board 100 is initially in a horizontal position, the slide pin 330 is at the bottom of a V-shaped groove 360, that is, Fig.24 The first stopper 391 is used to block the first stopper 391, so that the sliding pin 330 overcomes the force of the second spring 380 on one side (the left side in the figure, hereinafter referred to as the left side) during the upward movement, and is pushed by the second spring 380 on the other side (the right side in the figure, hereinafter referred to as the right side) to slide toward the left side of the V-shaped groove 360. The bed board 100 is continuously moved upward. Under the action of the left side of the V-shaped groove 360, the sliding pin 330 overcomes the force of the second spring 380 on its left side and slides to the left relative to the bed board 100. The sliding pin 330 slides along the left side of the V-shaped groove 360 ​​and enters the first guide section 313. The bed board 100 is continuously moved upward. The sliding pin 330 slides upward along the first guide section 313. When the sliding pin 330 moves to the upper end of the first guide section 313, that is, the attached Fig.24 When the bed board 100 is at the middle point C, the force applied by the person to the bed board 100 is blocked, and the bed board 100 can be lowered, and the sliding pin 330 moves downward accordingly. Due to the influence of the second spring 380, the sliding pin 330 automatically enters the left side of the other V-shaped groove 360 ​​and slides along it to the bottom of the other V-shaped groove 360, that is, the bed board 100 is lowered. Fig.24When the bed board 100 is at point B, the person no longer applies force to the bed board 100, and the sliding pin 330 is stabilized at this point, and the bed board 100 completes the conversion from the horizontal position to the inclined position; when the bed board 100 needs to be restored to the horizontal position, the bed board 100 is pulled upward. Due to the obstruction of the second limit head 392, the sliding pin 330 overcomes the force of the second spring 380 on the right side during the upward movement, and is pushed by the second spring 380 on the left side to slide toward the right side of the other V-shaped groove 360, and the bed board 100 is continued to be pulled upward. Under the action of the right side of the other V-shaped groove 360, the sliding pin 330 overcomes the force of the second spring 380 on the right side and slides to the right side relative to the bed board 100. When the sliding pin 330 slides to the uppermost end along the left side of the other V-shaped groove 360, that is, attached Fig.24 When the bed board 100 is at the middle point D, the force applied by the person to the bed board 100 is blocked, and the bed board 100 can be lowered, and the sliding pin 330 moves downward accordingly. Due to the setting of the notch 393, the sliding pin 330 is pushed by the force of the second spring 380 on the right side during the downward movement and automatically enters the second guide section 314. The bed board 100 is further lowered, and the sliding pin 330 slides downward along the second guide section 314 to the lower end of the second guide section 314, that is, attached. Fig.24 At point E, the bed board 100 is lowered further, and the bed board 100 enters the right side of a V-shaped groove 360 ​​and slides down along it to reach the lowest point, i.e., point A. At this time, the person no longer applies force to the bed board 100, and the sliding pin 330 is stabilized at this position, and the bed board 100 completes the conversion from the inclined position to the horizontal position. Through the above steps, the bed board 100 achieves the purpose of adjusting the angle.
