[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0030] A synchronous guiding mechanism for opening and closing during the overall operation of a new type of nursing table, including two arc plates 1 of the nursing table. The bottom side and the middle of the interior of the arc plate 1 of the nursing table are both provided with an opening and closing assembly 2. The top of the interior of the arc plate 1 of the nursing table is provided with a positioning and bearing assembly 4. The positioning and bearing assembly 4 includes a loading block 401 clamped on the top side of the interior of the arc plate 1 of the nursing table. Universal wheels 10 are bolted to both sides of the bottom of the arc plate 1 of the nursing table. Clamping blocks 11 are fixedly connected to the top of the front side and the rear side of the interior of the arc plate 1 of the nursing table;

[0031] The opening and closing assembly 2 includes a fixed block 201 bolted to the bottom side of the interior of the arc plate 1 of the nursing table. The outer side of the fixed block 201 is rotatably connected with a rotating sleeve 202. The front side of the rear rotating sleeve 202 is rotatably connected with a rear folding plate 203. The rear side of the front rotating sleeve 202 is rotatably connected with a front folding plate 204. The rear side of the front folding plate 204 is rotatably connected with the front side of the rear folding plate 203.

[0032] In this embodiment: When it is necessary to change the nursing table from the retracted state to the open state, first apply an outward pulling force to the two nursing table arc plates 1. The pulling force acts on the two nursing table arc plates 1, causing the nursing table arc plates 1 to start moving outward. As the nursing table arc plates 1 move, the rotating sleeves 202 on the outer sides of the fixing blocks 201 inside the nursing table arc plates 1 are rotatably connected to the fixing blocks 201. During the movement of the nursing table arc plates 1, the rotating sleeves 202 start to rotate around the fixing blocks 201. At the same time, the rear folding plates 203 connected to the rear rotating sleeves 202 also start to gradually unfold synchronously with the front folding plates 204 connected to the front rotating sleeves 202. The front folding plates 204 and the rear folding plates 203 gradually unfold into a stable support structure, which provides a supporting force for the nursing table arc plates 1, enabling the nursing table arc plates 1 to remain in the open state. After the nursing table arc plates 1 are opened, place the positioning and bearing assembly 4 on the top side inside the nursing table arc plates 1 to ensure the stability of the opening and closing assembly 2 after opening. Moreover, a sunken space is formed on the top side inside the nursing table arc plates 1. At this time, the state formed by the nursing table arc plates 1 cooperating with the positioning and bearing assembly 4 is the nursing table mode, so as to place a child on the positioning and bearing assembly 4 for nursing use. When the child grows up and no longer needs to use the nursing table, make the positioning and bearing assembly 4 engage with the clamping blocks 11 inside the nursing table arc plates 1, so as to form a platform between the positioning and bearing assembly 4 and the nursing table arc plates 1. The usage state at this time is the writing desk or workbench mode, thereby extending the product function and enhancing the user experience.

[0033] Specifically, as Figure 3 shown, a positioning carrier plate 402 is provided on the top side inside the nursing table arc plate 1, and the positioning carrier plate 402 is located on top of the carrier block 401.

[0034] Specifically, as Figure 3 shown, clamping grooves 403 are provided on both the front side and the rear side of the positioning carrier plate 402, and the clamping grooves 403 are used in cooperation with the clamping blocks 11.

[0035] Specifically, as Figure 3 shown, a comfort pad 404 is embedded inside the inner side of the top of the positioning carrier plate 402, and the comfort pad 404 is prepared from a food-grade antibacterial rubber material.

[0036] In this embodiment: When the nursing table arc plate 1 is fully opened, hold the positioning carrier plate 402 and place the positioning carrier plate 402 on the carrier block 401 on the inner top side of the nursing table arc plate 1, so that the positioning carrier plate 402 plays a role in supporting the nursing table arc plate 1 to stabilize the shaking or displacement of the nursing table during use. Moreover, a sunken space is formed on the inner top side of the nursing table arc plate 1. At this time, the state formed by the cooperation of the nursing table arc plate 1 and the positioning carrier plate 402 is the nursing table mode. Then place the child on the positioning carrier plate 402 for nursing use. Through the comfort pad 404 provided on the top of the positioning carrier plate 402, the comfort of use is improved. When the child grows up and no longer needs to use the nursing table, take out the positioning carrier plate 402 upward, and then make the card slot 403 at the bottom of the positioning carrier plate 402 snap into the card block 11 inside the nursing table arc plate 1, so as to form a platform between the positioning carrier plate 402 and the nursing table arc plate 1. At this time, the use state is the writing desk or workbench mode, thus extending the product function.

[0037] Specifically, as Figure 2 、 Figure 3 、 Figure 5 shown, on both sides of the outer top of the nursing table arc plate 1, through holes 5 are provided, and a U-shaped storage rack 6 is inserted into the inside of the through holes 5.

[0038] Specifically, as Figure 1 、 Figure 2 、 Figure 5 shown, a bearing plate 7 is clamped on the outside of the nursing table arc plate 1, and the top of the bearing plate 7 is horizontal with the top of the U-shaped storage rack 6. A basin 8 is placed on the tops of the bearing plate 7 and the U-shaped storage rack 6.

[0039] In this embodiment: The design of the bearing plate 7 and the U-shaped storage rack 6 provides additional placement space for the nursing table, and items such as the basin 8 can be placed, which is convenient for taking during the nursing process, greatly improving the practicality of the nursing table. Moreover, both the bearing plate 7 and the U-shaped storage rack 6 are clamped, and this clamping method makes the installation and disassembly of the bearing plate 7 and the U-shaped storage rack 6 very convenient. When the bearing plate 7 and the U-shaped storage rack 6 are needed, they can be quickly installed on the nursing table arc plate 1, and when they are not needed, they can be easily removed to facilitate the folding, storage, and transportation use of the nursing table.

[0040] Specifically, as Figure 1 、 Figure 2 shown, a reinforcement plate 3 is clamped on the left side inside the nursing table arc plate 1, and the inner side of the reinforcement plate 3 contacts the left side of the positioning carrier plate 402.

[0041] Specifically, as Figure 4 shown, flow-through grooves 9 are provided at the tops of the rear folding plate 203 and the front folding plate 204, and the flow-through grooves 9 are in an arc shape.

[0042] In this embodiment: By clamping the reinforcement plate 3 inside the left side of the nursing table arc plate 1 and contacting the left side of the positioning carrier plate 402, additional support force is provided for the nursing table arc plate 1, preventing the nursing table arc plate 1 from deforming or twisting during use, thereby enhancing the structural stability of the entire nursing table. By opening the circulation groove 9, the weight of the rear folding plate 203 and the front folding plate 204 can be reduced to a certain extent, making the nursing table more lightweight and flexible when opening and closing, reducing the operation difficulty and physical consumption.

[0043] Working principle: When the nursing table needs to be used and is changed from the retracted state to the open state, first apply an outward pulling force to the two nursing table arc plates 1. The pulling force acts on the two nursing table arc plates 1, causing the nursing table arc plates 1 to start moving outward. As the nursing table arc plates 1 move, the rotating sleeves 202 on the outside of the fixing blocks 201 inside the nursing table arc plates 1 are rotationally connected to the fixing blocks 201. During the movement of the nursing table arc plates 1, the rotating sleeves 202 start to rotate around the fixing blocks 201. At the same time, the rear folding plates 203 connected to the rear rotating sleeves 202 start to gradually unfold synchronously with the front folding plates 204 connected to the front rotating sleeves 202. The front folding plates 204 and the rear folding plates 203 gradually unfold into a stable support structure, which provides a supporting force for the nursing table arc plates 1, enabling the nursing table arc plates 1 to remain in the open state. When the nursing table arc plates 1 are fully opened, hold the positioning carrier plate 402 and place the positioning carrier plate 402 on the carrier block 401 on the top side inside the nursing table arc plates 1, so that the positioning carrier plate 402 plays a role in supporting the nursing table arc plates 1 to stabilize the shaking or displacement of the nursing table during use. Moreover, a sunken space is formed on the top side inside the nursing table arc plates 1. At this time, the state formed by the nursing table arc plates 1 in cooperation with the positioning carrier plate 402 is the nursing table mode, and then place the child on the positioning carrier plate 402 for nursing use. Then, through the comfort pad 404 provided on the top of the positioning carrier plate 402, the comfort of use is improved. When the child grows up and no longer needs to use the nursing table, take out the positioning carrier plate 402 upward, and then make the card slot 403 at the bottom of the positioning carrier plate 402 snap into the card block 11 inside the nursing table arc plates 1, so that a platform is formed between the positioning carrier plate 402 and the nursing table arc plates 1. At this time, the use state is the writing desk or workbench mode, thus extending the product function. Then, when it is necessary to change the nursing table from the open state to the retracted state, when it is necessary to change the nursing table arc plates 1 from the open state to the retracted state, directly take out the positioning carrier plate 402 from the inside of the nursing table arc plates 1 to make the card slot 403 disengage from the inside of the carrier block 401. Then, apply an inward pushing force to the two nursing table arc plates 1. The pushing force acts on the two nursing table arc plates 1, causing the nursing table arc plates 1 to start moving inward. During the movement of the nursing table arc plates 1, the rotating sleeves 202 start to rotate reversely around the fixing blocks 201. Driven by the front folding plates 204 connected to the front rotating sleeves 202, the rear folding plates 203 connected to the rear rotating sleeves 202 also start to gradually rotate and fold in opposite directions between the front folding plates 204 and the rear folding plates 203. As the nursing table arc plates 1 continue to move inward, the front folding plates 204 and the rear folding plates 203 gradually fold on top of each other, reducing the occupied space. When the two nursing table arc plates 1 on both sides are fully retracted, the volume of the entire nursing table becomes smaller, facilitating storage and transportation.

[0044] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
