As shown in Figures 1 and 16, the present invention provides a crib comprising a bassinet 100, a bed frame 200, a support base 300, and a locking mechanism 400. The crib can be used as a place for a child to sleep or play, while also serving as a cradle to comfort the child. It has a simple structure and is easy to operate. Specifically, as shown in Figure 6, the sleeping cot 100 is a roughly rectangular box-shaped structure. Of course, the shape of the sleeping cot 100 is not limited to this and can also be designed as an elliptical cylinder or other shapes as needed. The sleeping cot 100 forms a space for accommodating a child, allowing them to sleep, play, etc. In this embodiment, the sleeping cot 100 has a rectangular frame structure composed of multiple support rods 110, namely, the top of the frame structure forms a rectangular frame. The two support rods 110 located on the short sides of the rectangular frame serve as the sliding rods 110a. Of course, other support rods 110 that constitute the frame structure can also serve as the sliding rods 110a, such as the two support rods 110 located on the long sides of the rectangular frame, and this is not limited. In this embodiment, as shown in Figure 10, the sliding rods 110a are straight rods. Of course, in other embodiments, the sliding rods 110a can also be curved rods. For example, as shown in Figure 11, the sliding rods 110a can be curved rods that are concave and curved toward the ground. Of course, the sliding rod 110a can be an arc-shaped rod that is concave and curved away from the ground, etc., and is not limited to this. The frame structure can be covered with fabric (not shown), and a support pad (not shown) can be provided at the bottom of the frame structure to form a protective barrier for children. Specifically, as shown in Figure 1, the bed frame 200 is used to support the sleeping basket 100. In this embodiment, the bed frame 200 includes two support columns 210, and the two support columns 210 are respectively located on the two short sides of the rectangular frame, and are respectively used to support two sliding rods 110a. Of course, in other embodiments, the number and position settings of the support columns 210 can also be adjusted as needed. The support columns 210 include interconnected columns 211 and support legs 212. The support legs 212 are located at the bottom of the columns 211, and the support legs 212 and the columns 211 roughly form an inverted "T" shape structure. Such a setting can improve the supporting stability of the support columns 210. Of course, the setting method of the support columns 210 is not limited to this. Furthermore, as shown in Figures 1 to 5, both support columns 210 are height-adjustable. The height adjustment method for support columns 210 is not limited. For example, the column 211 may include a first sleeve rod 2111, a second sleeve rod 2112, and a height adjustment handle 2113. The first sleeve rod 2111 partially sleeves within the second sleeve rod 2112, and the first sleeve rod 2111 is located below the second sleeve rod 2112. The first sleeve rod 2111 is provided with a plurality of adjustment holes 2114 along the height direction. The height adjustment handle 2113 sleeves onto the second sleeve rod 2112 and can slide along the second sleeve rod 2112. The second sleeve rod 2112 is provided with an adjustment pin 2115, which is connected to the height adjustment handle 2113 via a connector 2116. The height adjustment handle 2113 can be operated to insert or remove the adjustment pin 2115 into or out of the adjustment hole 2114. When the adjustment pin 2115 is removed from the adjustment hole 2114, the first connecting rod 2111 and the second connecting rod 2112 can slide relative to each other to adjust the height of the support column 210. Once fully adjusted, the height adjustment handle 2113 can be operated to reinsert the adjustment pin 2115 into the adjustment hole 2114 under the action of the reset member 2117, thereby locking the first connecting rod 2111 and the second connecting rod 2112. As needed, the height adjustment handle 2113 can adjust the height of both support columns 210 simultaneously or only one of them. When the heights of both support columns 210 are adjusted simultaneously, the bottom of the sleeping cot 100 is horizontal. When the height of only one of the support columns 210 is adjusted, the bottom of the sleeping cot 100 is tilted, as shown in Figure 24. This provides multiple usage modes for children. Specifically, as shown in Figure 1, there are two support bases 300, each fixed to the top of the two support columns 210, that is, the ends of the two columns 211 away from the corresponding support legs 212. The support base 300 includes a supporting body 310 and an insertion portion (not shown) that are interconnected. The end of the column 211 away from the corresponding support leg 212 has an insertion slot (not shown) that cooperates with the insertion portion. The insertion portion is inserted into the insertion slot to achieve the connection between the support base 300 and the support column 210, and the support body 310 is located at the end of the column 211 away from the corresponding support leg 212. Of course, the number, location, and arrangement of the support bases 300 are not limited to this and can be adjusted according to actual needs. Furthermore, as shown in Figures 10 and 11, the support body 310 has a passage 311, and the slide bar 110a is inserted into the passage 311 and can slide back and forth relative to the support base 300. In this way, the sleeping basket 100 can be pushed and pulled back and forth to achieve the rocking of the sleeping basket 100 relative to the bed frame 200, which plays a role in soothing the child in the sleeping basket 100, and the structure is simple and easy to operate. When the slide bar 110a is a straight rod, as shown in Figure 10, the sleeping basket 100 can be swung back and forth in the horizontal direction. When the slide bar 110a is an arc-shaped rod, for example, an arc-shaped rod that is concave and curved toward the ground, as shown in Figure 11, the sleeping basket 100 can also be swung back and forth in both the horizontal and vertical directions. Furthermore, as shown in Figures 10 and 11, the support base 300 is further provided with rollers 312 that protrude from the passage 311. The rollers 312 abut against the slide bar 110a. This allows the slide bar 110a to slide more smoothly relative to the support base 300. In this embodiment, there are four rollers 312, two of which are spaced apart on the upper side of the slide bar 110a, and the other two are spaced apart on the lower side of the slide bar 110a. This achieves a better smoothing effect. Of course, in other embodiments, the number and location of the rollers 312 can also be adjusted as needed. Specifically, as shown in Figures 15 to 18 , the locking mechanism 400 includes a first locking portion, a second locking portion, an elastic member 410, and an operating member. When the locking mechanism 400 is locked, the sleeping cot 100 is fixed relative to the support base 300. When the locking mechanism 400 is released, the sleeping cot 100 can slide relative to the support base 300. Optionally, as shown in Figures 16 and 18 , the first locking portion is a locking hole 420 provided on the slide bar 110a, and the second locking portion is a locking pin 430 provided on the support base 300 and capable of inserting and mating with the locking hole 420. The locking pin 430 can be operated to engage or disengage with the locking hole 420, thereby placing the locking mechanism 400 in a locked or released state. In this embodiment, there is a single locking hole 420 located approximately in the middle of the slide bar 110a. Of course, in other embodiments, there may be multiple locking holes 420 arranged along the extension of the slide bar 110a, so that the sleeping cot 100 can be fixed in different positions relative to the bed frame 200. The locking pin 430 is provided with an abutment flange 431. Of course, in other embodiments, the first and second locking portions may also take other forms, such as a locking groove as the first locking portion and a locking protrusion as the second locking portion, which is not limited thereto. Specifically, the operating member can be in various forms. For example, in one embodiment, as shown in Figures 1 and 12 to 14, the operating member can be a knob 440 mounted on the support base 300. The knob 440 is roughly cylindrical in structure, and a plurality of rotating protrusions 441 are circumferentially provided on the side wall of the knob 440 to facilitate the caregiver to perform the rotation operation. The knob 440 is provided with a first mounting groove 442 facing the support base 300, and a driving rib 443 is provided on the side wall of the first mounting groove 442. In this embodiment, there are two driving ribs 443, which are arranged opposite to each other. Of course, in other embodiments, the number and setting position of the driving ribs 443 can also be adjusted as needed. As shown in Figure 13, the support base 300 is provided with a first mounting boss 313. A first mounting hole 313a is located in the center of the first mounting boss 313, which communicates with the locking hole 420 (see Figures 16 and 18). A locking pin 430 is movably inserted into the first mounting hole 313a. A driving ramp 313b is provided on the sidewall of the first mounting boss 313, which engages with a driving rib 443. The driving ramp 313b has two ends, a first stop 313c and a second stop 313d, respectively. There are two driving ramps 313b, corresponding to the two driving ribs 443. A knob 440 is rotatably mounted on the first mounting boss 313, so that the first mounting boss 313 is fully or partially accommodated within a first mounting groove 442. The bottom wall of the first mounting groove 442 is connected to the end of the locking pin 430 facing away from the slide bar 110a. Specifically, the locking pin 430 is secured to the bottom wall of the first mounting groove 442 via rivets. In this way, when the knob 440 is rotated, the driving rib 443 moves along the driving inclined surface 313b to move the locking pin 430 toward or away from the locking hole 420, and when the driving rib 443 moves to the first stop position 313c, the locking pin 430 is released from the locking hole 420; when the driving rib 443 moves to the second stop position 313d, the locking pin 430 can be inserted and engaged with the locking hole 420. 16 and 18 , the elastic member 410 is sleeved on the locking pin 430, with both ends of the elastic member 410 respectively abutting against the abutting flange 431 and the bottom wall of the first mounting groove 442. Thus, the elastic member 410 constantly forces the locking pin 430 to move toward the locking hole 420. The specific operating principle of the locking mechanism 400 of this embodiment is as follows: When the sleeping basket 100 is to be rocked, the knob 440 is rotated so that the driving rib 443 on the knob 440 moves along the driving inclined surface 313b from the second stop position 313d to the first stop position 313c, and at the same time drives the locking pin 430 originally inserted in the locking hole 420 to disengage from the locking hole 420, as shown in Figures 16 and 18. At this time, the locking mechanism 400 is unlocked, and the slide bar 110a can slide relative to the support seat 300, that is, pushing the sleeping basket 100 can realize the rocking function of the sleeping basket 100 relative to the bed frame 200, as shown in Figures 7 to 9. To stop the swaying of the sleeping cot 100 and secure it relative to the bed frame 200, the knob 440 can be rotated, causing the driving rib 443 on the knob 440 to move along the driving slope 313b from the first stop position 313c back to the second stop position 313d. As the bottom wall of the first mounting groove 442 gradually approaches the locking hole 420, the locking pin 430 contacts the slide bar 110a, compressing and deforming the elastic member 410. At this point, the sleeping cot 100 is pushed and pulled, causing the slide bar 110a to move to the support base 300 approximately in the middle of the slide bar 110a. The locking hole 420 aligns with the first mounting hole 313a. The locking pin 430, now automatically aligned and inserted into the locking hole 420 on the slide bar 110a under the elastic force of the elastic member 410, is then re-locked to the bed frame 200, as shown in Figures 18 and 16. For another example, as shown in Figures 19 to 23, the operating member can be a button 450, which has a roughly elliptical cylindrical structure. The button 450 has a pressing surface 451 for applying force. The pressing surface 451 is a V-shaped surface, and has a first pressing end 451a and a second pressing end 451b. The first pressing end 451a and the second pressing end 451b are separated by a depression in the middle of the V-shaped surface. The button 450 has a second mounting groove 452, and the locking pin 430 is partially disposed in the second mounting groove 452. A guide post 452a is provided on the groove wall of the second mounting groove 452. The locking pin 430 is provided with an elongated guide groove 432 arranged along the extension direction of the locking pin 430. The guide post 452a is inserted into the guide groove 432 to enable the locking pin 430 to move relative to the button 450. Such arrangement enables the locking pin 430 to be connected to the button 450 and to be displaced to a certain extent relative to the button 450 in a direction approaching or moving away from the locking hole 420, as shown in FIG. 20 and FIG. 21 . As shown in Figures 20 and 21, a mounting base 314 is provided on the support base 300, and a button 450 is movably provided on the mounting base 314. The end of the locking pin 430 away from the slide rod 110a is connected to the first pressing end 451a. When the first pressing end 451a is pressed, the first pressing end 451a moves toward the direction close to the locking hole 420, and the second pressing end 451b moves away from the locking hole 420; when the second pressing end 451b is pressed, the second pressing end 451b moves toward the direction close to the locking hole 420, and the first pressing end 451a moves away from the locking hole 420. Furthermore, as shown in Figures 19 to 23, a first engaging portion is provided on the mounting base 314, and a second engaging portion is provided on the side of the button 450 near the second pressing end 451b. In this embodiment, the first engaging portion is a engaging hole 314a, and the second engaging portion is a engaging finger 453, which is provided with a engaging hook 453a. When the second pressing end 451b is pressed, the engaging hook 453a is inserted into the engaging hole 314a. In this way, when the pressing force is removed, the button 450 maintains the state in which the second pressing end 451b is close to the locking hole 420 and the first pressing end 451a is away from the locking hole 420, as shown in Figure 23. In other words, simply pressing the second pressing end 451b once can keep the locking mechanism 400 in the released state. When the first pressing end 451a is pressed, the engaging finger 453 can undergo a certain elastic deformation, so the engaging hook 453a is disengaged from the engaging hole 314a, as shown in Figures 20 and 21, thereby not hindering the locking of the locking mechanism 400. Furthermore, as shown in Figures 19 to 23, the mounting base 314 is provided with a second mounting boss 314b, which has a receiving slot 314c connected to the through-passage 311. A second mounting hole 314d is provided in the middle of the second mounting boss 314b and connected to the receiving slot 314c. A locking pin 430 is movably inserted into the second mounting hole 314d. The elastic member 410 is sleeved on the locking pin 430, with the ends of the elastic member 410 respectively abutting against the abutting flange 431 and the bottom wall of the receiving slot 314c. In this way, the elastic member 410 constantly forces the locking pin 430 to move toward the locking hole 420. The specific operating principle of the locking mechanism 400 of this embodiment is as follows: To rock the cot 100, the second pressing end 451b of the button 450 is pressed. This moves the second pressing end 451b toward the locking hole 420, while the first pressing end 451a simultaneously moves away from the locking hole 420. This disengages the locking pin 430, which was originally inserted into the locking hole 420, and moves the guide post 452a to the end of the guide slot 432 away from the locking hole 420, as shown in FIG23 . The locking mechanism 400 is released, and the slide bar 110a can slide relative to the support base 300, thereby pushing the cot 100 to rock relative to the bed frame 200. Simultaneously, the second pressing end 451b moves toward the locking hole 420, causing the engaging hook 453a on the engaging finger 453 to engage with the engaging hole 314a, thereby maintaining the locking mechanism 400 in the released state. To stop the sleeping cot 100 from rocking and secure it relative to the bed frame 200, the first pressing end 451a of the button 450 is pressed, and the second pressing end 451b is moved away from the locking hole 420, causing the engaging hook 453a on the engaging finger 453 to disengage the engaging hole 314a. The first pressing end 451a then moves toward the locking hole 420, simultaneously pushing the locking pin 430 toward the locking hole 420. The locking pin 430 abuts against the slide bar 110a, compressing and deforming the elastic member 410, as shown in FIG19 . At this time, the sleeping cot 100 is pushed and pulled, so that the slide bar 110a moves to the support base 300 approximately in the middle of the slide bar 110a, and the locking hole 420 is aligned with the second mounting hole 314d. At this time, the locking pin 430 can automatically align and insert into the locking hole 420 on the slide bar 110a under the elastic force of the elastic member 410, as shown in Figure 21, to achieve the re-locking of the sleeping cot 100 and the bed frame 200. For another example, as shown in Figures 25 and 29, the operating member can be a pressing member 460, which is roughly a columnar structure. One end of the pressing member 460 is provided with a pressing portion 461, and the other end of the pressing member 460 is provided with an abutting boss 462. The locking pin 430 is fixed to one side of the pressing member 460 and is located between the pressing portion 461 and the abutting boss 462. In this embodiment, the locking pin 430 and the pressing member 460 are roughly perpendicular to each other. The support seat 300 is provided with an assembly groove 315 connected to the through-channel 311. The pressing member 460 is movably arranged in the assembly groove 315. The pressing portion 461 at least partially protrudes from the outside of the support seat 300 to apply a pressing force. The pressing direction of the pressing portion 461 is perpendicular to the extension direction of the locking pin 430. Specifically, the arrangement of the locking hole 420 in this embodiment differs slightly from that in the two preceding embodiments. In the two preceding embodiments, the knob 440 or button 450 is operated to move the locking pin 430 toward or away from the locking hole 420 in the horizontal direction ( FIG. 16 ) or the vertical direction ( FIG. 20 ) to achieve insertion locking or release with the locking hole 420. Therefore, the locking hole 420 is located on the left side as shown in FIG. 15 or FIG. 17 . In this embodiment, however, the pressing member 460 is operated to move the locking pin 430 toward or away from the locking hole 420 in the vertical direction ( FIG. 29 ) to achieve insertion locking or release with the locking hole 420. Therefore, the locking hole 420 is located on the upper left side as shown in FIG. 29 . This allows the pressing member 460 to be pressed downward. When the locking pin 430 moves downward, it is not blocked by the wall of the slide bar 110 a, allowing it to be smoothly inserted into the locking hole 420. 29 and 31 , a base 316 is provided near the bottom of the support base 300, and the two ends of the elastic member 410 respectively abut against the base 316 and the abutting boss 462. Thus, the elastic member 410 constantly causes the abutting boss 462 to move upward, thereby constantly moving the locking pin 430 toward the unlocked position. Furthermore, as shown in Figures 22 to 35 , the locking mechanism 400 also includes a retaining assembly 470. When the pressing member 460 is in the locked position, the retaining assembly 470 constantly maintains the pressing member 460 in the locked position. Specifically, the retaining assembly 470 includes a retaining frame 471 and a retaining member 472. The retaining frame 471 is generally square (as shown in Figures 29 and 31 ). The bottom of the retaining frame 471 is pivotally connected to the base 316, and the top of the retaining frame 471 (i.e., the end away from the base 316) is disconnected in the middle, forming two opposing snap-fitting portions 471a. The two snap-fitting portions 471a are respectively snap-fitted to the two sides of the retaining member 472. Of course, in other embodiments, only one snap-fitting portion 471a may be snap-fitted to the retaining member 472. As shown in Figures 32 to 35, the retaining member 472 is fixed to the pressing member 460. The retaining member 472 and the pressing member 460 can be formed as one piece or as two separate components. The retaining member 472 includes a retaining body 472a and a limiting block 472b fixed to the retaining body 472a. The retaining body 472a and the limiting block 472b can be formed as one piece or as two separate components. The limiting block 472b has a first limiting protrusion 472c and a second limiting protrusion 472d on the side near the pressing portion 461. The first limiting protrusion 472c and the second limiting protrusion 472d enclose a limiting groove 472e. A guide channel 473 connected to the limiting groove 472e is formed between the limiting block 472b and the retaining body 472a, and the buckle portion 471a can move along the guide channel 473. When the pressing member 460 moves from the unlocked position to the locked position, the engaging portion 471a moves along the guide channel 473 and passes over the first limiting protrusion 472c to enter the limiting groove 472e. When the pressing member 460 moves from the locked position to the unlocked position, the engaging portion 471a moves along the guide channel 473 and passes over the second limiting protrusion 472d to disengage the limiting groove 472e. In this way, the retaining assembly 470 can constantly retain the pressing member 460 in the locked position. Specifically, as shown in Figures 32 to 35, the stopper 472b is roughly an inverted triangular block structure. The guide channel 473 is roughly divided into a first channel 473a, a second channel 473b, and a third channel 473c, which are arranged along the three sides of the triangle and are interconnected. The stopper groove 472e is located within the third channel 473c. The first channel 473a and the first stopper protrusion 472c are located on the opposite left side, while the second channel 473b and the second stopper protrusion 472d are located on the opposite right side. The retaining body 472a also has a receiving channel 474 located below the stopper 472b. The receiving channel 474 is arranged vertically and communicates with both the first channel 473a and the second channel 473b. The bottom corner 472f of the stopper 472b is offset toward the second channel 473b. The retaining body 472a is provided with a blocking protrusion 481, which is offset toward the first stopper protrusion 472c. When the pressing member 460 is pressed and moves from the unlocked position to the locked position, the engaging portion 471a located in the accommodating channel 474 moves obliquely upward along the first channel 473a due to the obstruction of the bottom corner 472f of the stop block 472b, and passes over the first stop protrusion 472c and enters the stop groove 472e, as shown in Figure 35. At this time, the engaging portion 471a is restrained between the first stop protrusion 472c and the second stop protrusion 472d. Therefore, after the pressing force applied to the pressing member 460 is removed, the pressing member 460 will not move upward under the action of the elastic member 410, that is, the pressing member 460 remains in the locked position. When the pressing member 460 is pressed again, due to the obstruction of the blocking protrusion 481, the snap-fit ​​portion 471a located in the limiting groove 472e disengages from the limiting groove 472e, passes over the second limiting protrusion 472d along the third channel 473c and enters the second channel 473b, and moves obliquely downward along the second channel 473b back to the accommodating channel 474, as shown in Figure 33, so that the pressing member 460 can move from the locked position to the unlocked position under the elastic force of the elastic member 410. The specific operating principle of the locking mechanism 400 of this embodiment is as follows: When the sleeping basket 100 is rocked, the pressing member 460 is pressed, so that the buckle portion 471a located in the limiting groove 472e disengages from the limiting groove 472e, passes over the second limiting protrusion 472d along the third channel 473c and enters the second channel 473b, and moves obliquely downward along the second channel 473b back into the accommodating channel 474, as shown in Figure 33, that is, the holding mechanism 400 releases the holding effect, and the pressing member 460 can move from the locked position to the unlocked position under the elastic force of the elastic member 410, that is, the pressing member 460 moves upward until the locking pin 430 disengages from the locking hole 420, as shown in Figures 26 and 31. To stop the sleeping cot 100 from rocking and secure it relative to the bed frame 200, the pressing member 460 can be pressed again, causing it to move from the unlocked position to the locked position. Specifically, the pressing member 460 moves downward until the locking pin 430 is inserted into the locking hole 420, as shown in Figures 27 and 29. Simultaneously, the engaging portion 471a within the accommodating channel 474 moves diagonally upward along the first channel 473a, passing over the first limiting protrusion 472c and entering the limiting groove 472e, thereby maintaining the pressing member 460 in the locked position, as shown in Figure 35. It should be noted that in the three embodiments described above, the two sliding bars 110a on opposite sides of the sleeping basket 100 can be locked or unlocked simultaneously through the corresponding locking mechanism 400 and the support base 300 on the two support columns 210, or can be locked or unlocked separately through the corresponding locking mechanism 400 and the support base 300 on the two support columns 210. For example, the sliding bar 110a on one side can slide relative to the support base 300, and the sliding bar 110a on the other side can be relatively fixed to the support base 300, so that the function of unilateral swinging can be realized. The above-mentioned crib has at least the following technical effects: In this crib, a sleeping cot 100 provides a space for a child to sleep or play in. The sleeping cot 100 is supported by a bed frame 200, and a sliding rod 110a extends through a passage 311 of a support base 300 on the bed frame 200, thereby achieving a sliding connection between the sliding rod 110a and the support base 300, thereby achieving a sliding connection between the sleeping cot 100 and the bed frame 200. This allows the sleeping cot 100 to rock relative to the bed frame 200 by pushing and pulling the sleeping cot 100 back and forth, thus soothing the child in the sleeping cot 100. This crib achieves the rocking function of the sleeping cot 100 through a simple structure and is easy to operate.
