Description

Technical Field

[0001] The utility model relates to a plastic dining table, in particular to a spliced ​​plastic dining table which can be expanded laterally. The whole dining table is assembled from two or more spliced ​​units, and the overall length of the plastic dining table can be changed according to the number of spliced ​​units. Background Art

[0002] The patent with the authorization announcement number "CN203341301U" discloses a splicing dining table, which is composed of multiple single tables and connecting tables. The single tables and connecting tables are provided with pin holes and pin boxes on their sides. The connecting pins can pass through the pin holes and are fastened by cooperating with the annular cards through the multiple rows of annular grooves on them. In addition, a rubber sleeve is covered at the bottom of each upright pole to increase stability. This design allows the dining table to be flexibly spliced ​​and separated as needed to meet the needs of different spaces and numbers of people.

[0003] The patent with the authorization announcement number "CN215271258U" discloses a spliced ​​combination structure of a picnic table. Through the design of the main board, the clamping plate and the height-adjustable table leg assembly, the table area can be flexibly expanded and the stability can be adapted to different terrains. The table leg assembly uses a threaded sleeve and a fixed screw to adjust the height, and the fixed rod on the side wall of the support leg enhances the supporting effect. The movable groove and through hole set on the main board cooperate with the sliding rod and spring mechanism to enable the table table to be stretched, retracted and quickly stored.

[0004] The existing dining tables cannot be quickly and easily adjusted according to the actual number of diners or the size of the available space, which makes it difficult to effectively use them in changing outdoor environments or gatherings of different sizes. In addition, the installation and disassembly process is usually complicated and lacks intuitive and simple operation steps, making it cumbersome for users to set up the dining table or store it, which increases the time cost and affects the user experience, highlighting the limitations of existing dining tables in terms of adaptability, convenience and practicality.

[0057] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0058] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0059] Embodiment 1

[0060] like Figures 1 to 3As shown, the laterally expandable splicing plastic dining table 100 includes a head splicing unit 10 and a tail splicing unit 30 arranged adjacent to each other to form a basic frame of the dining table. Preferably, the head splicing unit 10 and the tail splicing unit 30 are components with the same structure, which brings the technical advantages of standardized production and simplified maintenance, while ensuring the uniformity of the appearance and function of the two ends of the dining table, improving the overall aesthetics and user experience.

[0061] The front splicing unit 10 includes an assembleable front dining board 11 and a front supporting leg assembly 12. The rear splicing unit 30 includes an assembleable rear dining board 31 and a rear supporting leg assembly 32. Each splicing unit includes a dining board and a corresponding supporting leg assembly, which are connected in an assembleable manner, making the construction and disassembly of the dining table simple and quick.

[0062] Specifically, a front connecting plate 13 is provided on the inner side of the front dining board 11, and a rear connecting plate 33 is provided on the inner side of the rear dining board 31. The front connecting plate 13 and the rear connecting plate 33 are respectively connected by a fastening component t to ensure a stable connection between adjacent dining boards.

[0063] The connecting plates are arranged vertically, and the bottom edges of adjacent connecting plates are aligned and the inner walls are close to each other after splicing, and then they are fixedly connected by the fastening components t that are transversely penetrated and assembled. The vertical arrangement of the front connecting plate 13 and the rear connecting plate 33 ensures that the bottom edges of adjacent dining plates are aligned and the inner walls are close to each other when splicing, thereby providing a stable and continuous surface. This technical means reduces splicing errors and improves the aesthetics and symmetry of the overall structure.

[0064] Preferably, the fastening assembly t includes a plurality of screw assemblies distributed along the width direction of the dining board. This transverse fastening method increases the connection points, improves the stability of the connection and the firmness of the structure, and also makes the spliced ​​dining board flatter and enhances the load-bearing capacity.

[0065] In addition, the screw assemblies are distributed along the width of the dining board, which not only provides uniform fastening force, but also makes the installation and removal process simple and quick, making it convenient for users to assemble and store the dining table.

[0066] The connecting plate used to connect adjacent splicing units is hidden at the bottom of the tabletop, making the table surface neater and improving the overall aesthetics of the product.

[0067] like Fig. 9 and Fig.10As shown, the front and rear edges of the head dining board 11 and the tail dining board 31 are provided with plug holes p extending to the end faces of the dining boards, and the reinforcing tubes 40 are inserted into the plug holes p of the adjacent dining boards to strengthen the supporting force of the adjacent dining boards. The reinforcing tubes 40 are inserted into the plug holes p to connect the adjacent dining boards as a whole, which significantly improves the rigidity and bending resistance of the entire tabletop, making the dining table more stable when bearing weight and reducing the possibility of bending or deformation.

[0068] The provision of the plug hole p allows mechanical interlocking between the reinforcing tube 40 and the dining board, increasing the contact area and friction of the connection point, thereby improving the strength and reliability of the connection. While improving the reliability of the connection, this technical means also facilitates the disassembly between the reinforcing tube 40 and the plug hole p, thereby facilitating the user to adjust the length of the dining table or perform cleaning and maintenance as needed.

[0069] Moreover, by providing the insertion holes p at the front and rear edges of the dining board, the addition of the reinforcing tube 40 helps to more evenly distribute the stress on the tabletop, thereby reducing local stress concentration and extending the service life of the dining table.

[0070] The plug holes p are distributed along the length of the edge of the dining board, so that the distribution length of two adjacent plug holes p after splicing is equivalent to the length of the entire reinforcing tube 40. By evenly distributing the plug holes p along the length of the dining board, the reinforcing tube 40 can provide uniform support between adjacent dining boards, ensuring that the entire tabletop remains flat when subjected to force, and avoiding local deformation caused by uneven force.

[0071] The matching of the distribution length of the plug holes p and the length of the reinforcing tube 40 ensures that the reinforcing tube can accurately pass through the adjacent plug holes p, achieves accurate matching, and improves the accuracy of splicing and the integrity of the structure. In other words, this technical means reduces the need for precise alignment of the plug hole positions during splicing, improves splicing efficiency, and shortens installation time.

[0072] Preferably, each dining board and each supporting leg assembly is made of plastic material; plastic material is lighter than wood or metal, easy to carry and move, while maintaining good durability and impact resistance, suitable for frequent use and outdoor environments. In addition, unified material properties - using the same plastic material to manufacture all components ensures the consistency of the dining table in physical changes such as thermal expansion and contraction, reducing splicing problems caused by different materials.

[0073] Preferably, the edge of each dining board and each supporting leg is provided with a rattan surface f, which provides a natural and traditional appearance and enhances the aesthetics and decorative effect of the dining table.

[0074] In addition, as for the connection relationship between the dining board and the supporting leg assembly, each supporting leg assembly includes two supporting legs a, such as Figure 3As shown, the upper end of the supporting leg a and the bottom surface of the dining board are plug-in structures, and the specific technical means of the plug-in structure are as follows:

[0075] The first plug-in slots 51 are respectively arranged at the outer corners of the front dining board 11 and the rear dining board 31, and the upper ends of the support legs a are respectively inserted into the corresponding first plug-in slots 51. The first plug-in slots 51 cooperate with the plug-in frames a1 at the upper ends of the support legs a to achieve accurate positioning and fixation between the support legs and the dining boards.

[0076] like Fig.12 and Fig.13 As shown, a plug-in frame a1 is provided at the upper end of the support leg a, and each of the four end faces of the plug-in frame a1 is provided with a slot a2, and a pair of end faces of the plug-in frame a1 are provided with an elastic hook portion a3. A rib portion b2 is provided in the plug-in slot to cooperate with the slot a2, and a notch b3 is provided on the wall of the plug-in slot b1 to cooperate with the elastic hook portion a3.

[0077] The elastic hook a3 provides an automatic locking mechanism. When the support leg a is inserted into the insertion slot 51, the elastic hook will cooperate with the slot b3 to lock the support leg to prevent it from accidentally falling off during use.

[0078] Based on the above technical means, the groove a2 on the end face of the plug-in frame a1 cooperates with the rib b2 in the plug-in groove, and the interaction between the elastic hook a3 and the notch b3 allows the user to quickly insert and remove the supporting legs, thereby improving the assembly and storage efficiency of the dining table.

[0079] In addition, the plug-in frame a1 of the supporting leg a is inserted into the plug-in slot 51 at the bottom of the dining board so that the plug-in structure is in a hidden state, making the connection part neater in appearance and improving the overall aesthetics of the dining table.

[0080] Embodiment 2

[0081] like Figures 4 to 6 As shown, in this embodiment, a middle splicing unit 20 is connected between the front splicing unit 10 and the rear splicing unit 30 to extend the entire length of the dining table.

[0082] Specifically, the laterally expandable splicing plastic dining table 100 includes a head splicing unit 10, a middle splicing unit 20 and a tail splicing unit 30 arranged in sequence. The addition of the middle splicing unit 20 provides more flexibility, allowing the user to adjust the total length of the dining table according to the number of diners or space restrictions, so as to meet the dining needs of different sizes.

[0083] Through the modular middle splicing unit 20, the length of the dining table can be seamlessly extended, and the user can easily add or reduce the middle unit to adapt to different usage scenarios.

[0084] Of course, it should be noted that the middle splicing unit 20 takes into account the coordination of its connection with the head and tail units, and ensures its consistency and continuity with the head and tail splicing units after assembly.

[0085] The front splicing unit 10 includes an assembleable front dining board 11 and a front supporting leg assembly 12; the middle splicing unit 20 includes an assembleable middle dining board 21 and a middle supporting leg assembly 22; and the rear splicing unit 30 includes an assembleable rear dining board 31 and a rear supporting leg assembly 32.

[0086] The modular arrangement of the above-mentioned splicing units ensures the overall structural and visual consistency of the dining table. At the same time, the modular unit arrangement simplifies the assembly and disassembly process, and the user can easily add or remove the middle splicing unit 20 to adjust the length of the dining table according to needs. By flexibly adding or reducing splicing units, the available space can be maximized while avoiding space waste.

[0087] In addition, each splicing unit is equipped with a support leg assembly to ensure the stability of the dining table after splicing, reducing the bending or deformation caused by the tabletop being too long. The even distribution of the support leg assemblies in each unit helps to carry the weight more effectively and avoid local overload or damage.

[0088] The middle support leg assembly 22 can help evenly distribute the weight on the tabletop, reduce the pressure on the supporting points at both ends, and thus improve the load-bearing capacity of the dining table. The presence of the middle support leg assembly 22 significantly improves the overall stability of the dining table, especially in a long dining table, the middle support can effectively prevent the center from sagging or bending, and keep the tabletop flat.

[0089] A front connecting plate 13 is provided on the inner side of the front dining board 11, a middle connecting plate 23 is provided on both sides of the middle dining board 21, and a rear connecting plate 33 is provided on the inner side of the rear dining board 31. Adjacent connecting plates are connected by fastening components t. The connecting plates 13, 23, and 33 ensure the structural integrity of the dining boards when spliced, and provide a unified connecting component. The standardized connecting plate design helps to improve the splicing accuracy, so that the splicing units can be tightly combined.

[0090] In addition, the connecting plate allows flexible conversion between multiple middle dining boards and between the front and rear dining boards of the dining table, thereby improving the flexibility of use of each splicing unit.

[0091] Preferably, the connecting plates are arranged vertically, and the bottom edges of adjacent connecting plates are aligned and the inner walls are close to each other after being spliced, and then they are fixedly connected by the fastening components t that are transversely penetrated and assembled. The vertical arrangement of the front connecting plate 13 and the rear connecting plate 33 ensures that the bottom edges of adjacent dining plates are aligned and the inner walls are close to each other when spliced, thereby providing a stable and continuous surface. This technical means reduces splicing errors and improves the aesthetics and symmetry of the overall structure.

[0092] In addition, preferably, the fastening assembly t includes a plurality of screw assemblies distributed along the width direction of the dining board. This transverse fastening method increases the connection points, improves the stability of the connection and the firmness of the structure, and also makes the spliced ​​dining board flatter and enhances the load-bearing capacity.

[0093] In addition, the screw assemblies are distributed along the width of the dining board, which not only provides uniform fastening force, but also makes the installation and removal process simple and quick, making it convenient for users to assemble and store the dining table.

[0094] The connecting plate used to connect adjacent splicing units is hidden at the bottom of the tabletop, making the table surface neater and improving the overall aesthetics of the product.

[0095] like Fig. 9 and Fig.10 As shown, adjacent dining boards are connected by built-in reinforcing tubes 40 to strengthen the support of the dining boards. Specifically, the front and rear edges of each dining board are provided with plug holes p extending to the end faces of the dining boards, and the corresponding reinforcing tubes 40 are inserted into the plug holes p of the adjacent dining boards to strengthen the support of the adjacent dining boards.

[0096] The reinforcing tube 40 is inserted into the plug hole p to connect the adjacent dining boards into a whole, which significantly improves the rigidity and bending resistance of the entire table top, making the dining table more stable when bearing weight and reducing the possibility of bending or deformation.

[0097] The provision of the plug hole p allows mechanical interlocking between the reinforcing tube 40 and the dining board, increasing the contact area and friction of the connection point, thereby improving the strength and reliability of the connection. While improving the reliability of the connection, this technical means also facilitates the disassembly between the reinforcing tube 40 and the plug hole p, thereby facilitating the user to adjust the length of the dining table or perform cleaning and maintenance as needed.

[0098] Moreover, by providing the insertion holes p at the front and rear edges of the dining board, the addition of the reinforcing tube 40 helps to more evenly distribute the stress on the tabletop, thereby reducing local stress concentration and extending the service life of the dining table.

[0099] The plug holes p are distributed along the length of the edge of the dining board, so that the distribution length of two adjacent plug holes p after splicing is equivalent to the length of the entire reinforcing tube 40. By evenly distributing the plug holes p along the length of the dining board, the reinforcing tube 40 can provide uniform support between adjacent dining boards, ensuring that the entire tabletop remains flat when subjected to force, and avoiding local deformation caused by uneven force.

[0100] The matching of the distribution length of the plug holes p and the length of the reinforcing tube 40 ensures that the reinforcing tube can accurately pass through the adjacent plug holes p, achieves accurate matching, and improves the accuracy of splicing and the integrity of the structure. In other words, this technical means reduces the need for precise alignment of the plug hole positions during splicing, improves splicing efficiency, and shortens installation time.

[0101] In addition, as for the connection relationship between the dining board and the supporting leg assembly, each supporting leg assembly includes two supporting legs a, such as Figure 6 As shown, the upper end of the supporting leg a and the bottom surface of the dining board are plug-in structures, and the specific technical means of the plug-in structure are as follows:

[0102] The first plug-in slots 51 are respectively arranged at the outer corners of the front dining board 11 and the rear dining board 31, and the upper ends of the corresponding supporting legs a are respectively inserted into the corresponding first plug-in slots 51. The first plug-in slots 51 cooperate with the plug-in frames a1 at the upper ends of the corresponding supporting legs a to achieve accurate positioning and fixation between the supporting legs and the dining boards of the corresponding splicing units.

[0103] The middle position of the middle dining board 21 is provided with a plurality of second insertion slots 52 arranged along the length direction of the dining board, and the middle support leg a can be selectively inserted into one of the second insertion slots 52. The plurality of arranged second insertion slots 52 provide a flexible insertion point for the middle support leg a, and the position of the support leg can be adjusted according to actual needs to adapt to different dining table layouts and space requirements.

[0104] When it is necessary to insert a dining chair between the front support leg assembly and the middle support leg assembly, or between the rear support leg assembly and the middle support leg assembly, the flexible adjustment of the position of the support leg a enables the dining table 100 to more effectively utilize the space below it, providing a suitable insertion point for the dining chair, thereby optimizing the overall space layout. In addition, the properly arranged dining chairs make it easier for diners to get in and out of their seats, improving the fluidity and accessibility around the dining table.

[0105] In addition, in the utility model, the user can easily adjust the position of the supporting leg a according to the needs without complicated operations or tools, making the use of the dining table more convenient.

[0106] More specifically, if Fig.12 and Fig.13As shown, a plug-in frame a1 is provided at the upper end of the support leg a, and each of the four end faces of the plug-in frame a1 is provided with a slot a2, and a pair of end faces of the plug-in frame a1 are provided with an elastic hook portion a3. A rib portion b2 is provided in the plug-in slot to cooperate with the slot a2, and a notch b3 is provided on the wall of the plug-in slot b1 to cooperate with the elastic hook portion a3.

[0107] The elastic hook a3 provides an automatic locking mechanism. When the support leg a is inserted into the insertion slot 51, the elastic hook will cooperate with the slot b3 to lock the support leg to prevent it from accidentally falling off during use.

[0108] Based on the above technical means, the groove a2 on the end face of the plug-in frame a1 cooperates with the rib b2 in the plug-in groove, and the interaction between the elastic hook a3 and the notch b3 allows the user to quickly insert and remove the supporting legs, thereby improving the assembly and storage efficiency of the dining table.
