Description

Technical Field

[0001] The utility model relates to the technical field of baby cribs, in particular to a baby crib with a retractable fence. Background Art

[0002] A crib is a bed for infants and young children. There are fences on the side of the crib to prevent the baby from rolling over and falling off the bed while sleeping, which plays a role in protecting the baby. Generally, the height of the fence should be set to facilitate people to carry the baby in and out of the bed. In addition, the height of the baby is not designed to be particularly high because the baby is young. However, in actual use, although the baby cannot walk within one year old, he can crawl. The baby may climb the fence when playing in the bed. If the fence is not high enough, there will be safety hazards. If the fence is simply raised, it will be inconvenient to use. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a baby crib with a retractable fence.

[0004] The technical solution is: a baby bed with a retractable fence, including an outer shell, a mattress and a fence, a mattress is installed in the lower part of the outer shell, and the outer shell is symmetrically fixed with fences. It also includes knobs, rotating rods, bevel gears, screws, lifting frames and scale lines. The lifting frames are slidably connected to the two fences, the lower parts of the two fences are rotatably connected to the rotating rods, the rotating rods are rotatably connected to the outer shell, knobs are fixed on the right ends of the rotating rods, the two sides of the two fences are rotatably connected to the screws, the screws are threadedly connected to the lifting frames on the same side, bevel gears are fixed at the lower parts of the screws, bevel gears are also fixed on both sides of the two rotating rods, and every two adjacent bevel gears are meshed with each other. Scale lines are symmetrically engraved on the upper right side of the outer shell.

[0005] Furthermore, the rotation of the rotating rod can drive the screw to rotate through the bevel gear, and then drive the lifting frame to extend and shorten through the screw.

[0006] Furthermore, it also includes slide rails, sliders and protective covers. Slide rails are fixed on the tops of the two lifting frames. Slide blocks are symmetrically slidably connected to the two slide rails. A protective cover is connected between the tops of the four sliders, and the protective cover is located directly above the mattress.

[0007] Furthermore, it also includes a door and a handle. The right side of the lower part of the shell is rotatably connected with the door, and the handle is installed on the door.

[0008] Furthermore, the space below the mattress in the shell is used to store items, and the door can be opened to take out and store items.

[0009] Furthermore, it also includes universal wheels. Four universal wheels are evenly installed on the bottom of the shell to assist the movement of the device.

[0010] The beneficial effects of the utility model are as follows: 1. The rotating knob drives the rotating rod to rotate, and then the lifting frame can be driven to move upward through the screw rod to adjust the height of the lifting frame, thereby ensuring the safety of infants and young children, and the operation is simple and fast;

[0011] 2. A protective cover is installed on the lifting frame to block light, help infants and young children sleep, and provide a sense of security for them;

[0012] 3. The space under the mattress can store items, and a door is provided to facilitate people to take out items, making the device more convenient to use and more comprehensive in function. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] A baby crib with a retractable fence, such as Figure 1-Figure 4As shown, it includes an outer shell 1, a mattress 101, a fence 2, a knob 3, a rotating rod 4, a bevel gear 5, a screw 6, a lifting frame 7 and a scale line 11. The mattress 101 is installed in the lower part of the outer shell 1. The outer shell 1 is symmetrically fixed with fences 2. The two fences 2 are slidably connected with the lifting frames 7. The lower parts of the two fences 2 are rotatably connected with rotating rods 4. The rotating rods 4 are rotatably connected to the outer shell 1. The right ends of the rotating rods 4 are fixed with knobs 3. The left and right sides of the two fences 2 are rotatably connected. The screws 6 are threadedly connected to the lifting frame 7 on the same side. Bevel gears 5 are fixed to the lower parts of the four screws 6. Bevel gears 5 are also fixed on the left and right sides of the two rotating rods 4. Every two adjacent bevel gears 5 are meshed with each other. The rotation of the rotating rod 4 can drive the screw 6 to rotate through the bevel gear 5, and then the lifting frame 7 is extended and shortened through the screw 6. Scale lines 11 are symmetrically engraved on the upper right side of the outer shell 1.

[0021] The present device refers to a bed for infants to sleep. The infant can sleep and rest on the mattress 101, and the fence 2 will play a protective role. After the infant wakes up, he or she may play on the bed and climb the fence 2, which poses a safety hazard. At this time, people can turn the knob 3 to drive the rotating rod 4 to rotate, and the rotating rod 4 drives the screw 6 to rotate through the bevel gear 5, so that the screw 6 drives the lifting frame 7 to move upward along the fence 2, and the height of the lifting frame 7 can be adjusted. By looking at the scale line 11, the height of the lifting frame 7 can be known, which is convenient for people to adjust. After adjustment, just loosen the knob 3, thereby improving the safety of the fence 2 and ensuring the safety of the infant. Similarly, reversing the knob 3 can drive the rotating rod 4 to reverse, and then drive the bevel gear 5 and the screw 6 to reverse, and the screw 6 can drive the lifting frame 7 to move downward for adjustment.

[0022] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a slide rail 8, a slider 9 and a protective cover 10. The slide rails 8 are fixed on the top of the two lifting frames 7. The sliders 9 are symmetrically connected to the two slide rails 8 in a sliding manner. The protective cover 10 is connected between the tops of the four sliders 9. The protective cover 10 is located directly above the mattress 101. By pushing one side of the slider 9 to the other side, the protective cover 10 can be folded and stored.

[0023] like Figure 1 and Figure 2 As shown, it also includes a door 12, a handle 13 and a universal wheel 14. The door 12 is rotatably connected to the right side of the lower part of the shell 1, and the handle 13 is installed on the door 12. The position below the mattress 101 in the shell 1 is used to store items. When the door 12 is opened, items can be taken and stored. Four universal wheels 14 for assisting the movement of the device are evenly installed on the bottom of the shell 1.

[0024] The protective cover 10 can play a role in shielding from light and help infants and young children fall asleep. The slider 9 can slide on the slide rail 8. Pushing the slider 9 on one side to the other direction can push the protective cover 10 to be folded and stowed. Moving the sliders 9 apart from each other can unfold the protective cover 10. When the lifting frame 7 is raised and lowered, the protective cover 10 will be adjusted with the movement. When using this device, some quilts or clothes can be stored in the space under the mattress 101. When in use, pull the handle 13 to open the door 12 to take and store items. Reverse the door 12 to close the door 12. The universal wheel 14 can assist the outer shell 1 to move, which is convenient for changing the overall position of the device, and the universal wheel 14 can be self-locking and will not rotate at will.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
