[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] Reference Figures 1-2 and Figure 10 This utility model provides an embodiment of a foldable bassinet, including a connecting frame 1. The connecting frame 1 is provided in two sets, and a folding mechanism 4 is provided between the two sets of connecting frames 1. By providing the folding mechanism 4, the whole can be completely folded relative to each other, and can be transported when not in use. At the same time, it can also be adjusted at multiple angles to adjust the baby's posture in multiple positions. A fixing buckle 2 is fixedly connected to the center of the front end of the left connecting frame 1. A handle 3 is hinged to the surface of the fixing buckle 2. The hinge point of the handle 3 is above the fixing buckle 2. When the bassinet is folded, it can be rotated around the hinge point of the fixing buckle 2 by moving the handle 3.
[0038] Reference Figure 3 and Figure 5 A traction rope 5 is inserted into the inner side wall of the handle 3. Two sets of traction ropes 5 are provided on the inner side of the handle 3. By moving the handle 3, the two sets of traction ropes 5 can be moved synchronously and follow the handle 3 outward. The traction rope 5 passes through and is slidably connected to the inner wall of the connecting frame 1. A guide block is provided on the inner side wall of the fixing buckle 2. The outer wall of the traction rope 5 is in contact with the inner wall of the guide block of the fixing buckle 2. By providing two sets of guide blocks on the inner side of the fixing buckle 2, the movement of the traction rope 5 can be guided.
[0039] Reference Figures 5-7The folding mechanism 4 includes a fixed base 41. A positioning shaft 410 is fixedly connected to the center of the top of the fixed base 41. A limiting tooth block 45 is sleeved on the surface of the positioning shaft 410. The positioning shaft 410 can be used to position and install the limiting tooth block 45. A limiting tooth groove is formed on the inner wall of the top of the fixed base 41. The outer wall of the limiting tooth block 45 contacts the inner wall of the limiting tooth groove of the fixed base 41. The contact between the two allows the limiting tooth block 45 to be positioned and fitted. A rotary joint a42 contacts the outer surface of the limiting tooth block 45. The connecting bracket 1 is inserted into the inner wall of the rotary joint a42. The end of the rotary joint a42 near the limiting tooth block 45 also has a tooth groove and fits with the rotary joint a42. The limiting tooth block 45 is disengaged through the rotary joint a42. This allows the rotary joint b43 to move outward synchronously. The surface of the rotary joint a42 contacts the top of the fixed seat 41. The inner sidewall of the rotary joint a42 contacts a triangular block 49. A triangular groove matching the shape of the triangular block 49 is provided on the inner side of the rotary joint a42, which can position the triangular block 49 so that it will rotate synchronously when rotating. A limiting groove is provided on the inner sidewall of the rotary joint b43. The outer wall of the triangular block 49 contacts the inner wall of the limiting groove. The contact between the two can position and install the triangular block 49. A cavity is provided at the center of the triangular block 49. The triangular block 49 is rotatably connected to the surface of the positioning shaft 410. A rotating block b48 is rotatably connected to the inner sidewall of the triangular block 49.
[0040] Reference Figures 7-9Rotating block b48 is elastically connected to rotating block a46 via a return spring 47. One end of the return spring 47 is fixedly connected to the outer surface of rotating block b48, and the other end is fixedly connected to the outer surface of rotating block a46. The function of the return spring 47 is to automatically reset the position of rotating block a46 after it moves outward with the rotating joint b43. The outer wall of rotating block a46 is rotatably connected to the rotating joint b43. The surface of the rotating joint b43 is in contact with the surface of the rotating joint a42. The inner sidewall of the rotating joint a42 is elastically connected to the limiting wheel 412 via a connecting spring 411. One end of the connecting spring 411 is fixedly connected to the outer arc surface of the limiting wheel 412, and the other end is fixedly connected to the inner sidewall of the rotating joint a42. The function of 11 is to automatically reset the position of the traction rope 5 after it is pulled outward by the handle 3 and the limiting wheel 412 is rotated. The limiting wheel 412 is rotatably connected to the inner side wall of the rotating joint a42. The end of the traction rope 5 away from the handle 3 is sleeved on the inner wall of the bottom end of the limiting wheel 412. The bottom end of the limiting wheel 412 has a groove for fitting the traction rope 5. Three sets of protrusions 413 are fixedly connected to the inner side wall of the rotating joint a42. A toothed groove is provided at the center of the inner side of the limiting wheel 412. The outer wall of the protrusion 413 contacts the inner wall of the toothed groove. The contact between the two causes the limiting wheel 412 to pull the limiting wheel 412 to contact the protrusion 413 when it rotates, thereby squeezing the rotating joint a42 as a whole to move outward and the toothed groove on its inner side to disengage from the limiting toothed block 45.
[0041] Working principle: When the bassinet needs to be folded, the handle 3 is rotated around the hinge point above the fixing buckle 2. The two sets of traction ropes 5 inserted inside the handle 3 will move outward in sync with the handle 3. The traction ropes 5 pass through and slide on the inner wall of the connecting frame 1. Under the guidance of the two sets of guide blocks inside the fixing buckle 2, the traction ropes 5 will not deviate or entangle during the movement, and the tension will be transmitted stably.
[0042] The end of the traction rope 5 away from the handle 3 is fitted into the placement groove on the inner wall of the bottom of the limiting wheel 412. When the traction rope 5 is pulled by the handle 3, it will drive the limiting wheel 412 to rotate on the inner side wall of the rotating joint a42. The toothed groove at the center of the inner side of the limiting wheel 412 interacts with the three sets of protrusions 413 fixed on the inner side wall of the rotating joint a42. During the rotation of the limiting wheel 412, its toothed groove contacts the protrusions 413, which will generate an outward squeezing force on the rotating joint a42. After the rotating joints a42 and b43 move outward, they lose the constraint of the limiting toothed block 45, and the folding mechanism 4 between the two sets of connecting frames 1 can perform a folding action. The connection structure between the connecting frame 1 and the rotating joints a42 and b43 allows them to rotate. Under the action of the operator's external force, the connecting frame 1 rotates around the relevant hinge point, so that the entire sleeping basket is folded, reducing the space occupied and making it easy to store and carry.
[0043] When the bassinet needs to be unfolded, external force pushes the connecting frame 1 to the unfolded state. At this time, the rotating joints a42 and b43 return to their initial positions. The rotating block a46 is connected to the rotating block b48 through the return spring 47. During the reset process of the rotating joint b43, the rotating block a46 moves along with it. The return spring 47 plays a role in buffering and assisting the reset. At the same time, the connecting spring 411 pushes the limiting wheel 412 to reset, the traction rope 5 loosens, the limiting wheel 412 disengages from the protrusion 413, and the inner tooth groove of the rotating joint a42 re-engages with the limiting tooth block 45, completing the positioning and locking of the folding mechanism 4. The bassinet returns to a stable unfolded state.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
