Description

Technical Field

[0001] The utility model relates to the technical field of daily furniture, in particular to a table with an extendable tabletop. Background Art

[0002] A table is a commonly used piece of furniture. Users can place items, do things, eat, write, work, etc. on the table. The structure of a table generally consists of a table top and table legs arranged under the table top. The table top is supported by the table legs so that the table can be placed and used stably.

[0003] However, when people use a desk, they often feel that the area of ​​the desktop is small and the usable area of ​​the desktop cannot meet the user's usage requirements. Therefore, in recent years, it has become popular to develop a desk that can extend the desktop. For example, the Chinese invention patent publication number is: CN106108367A, which discloses a desk with an extension function. Its structure is that an extension plate is rotatably connected to the side wall of the desktop, and the extension plate can be rotated to open and close relative to the desktop. In this way, when the area of ​​the desktop is not enough, the user can rotate and open the extension plate, so that the length of the desktop can be extended and the usable area of ​​the desktop can be expanded. When the extension plate is not in use, the extension plate can be rotated and closed to restore the desktop area, so that it will not take up too much space.

[0004] However, the above table also has the following disadvantages, that is, the extension board is rotatably connected to the side wall of the tabletop, so that the extension board can only be rotated and opened in one direction relative to the tabletop, which is equivalent to the extension board can only be opened in the length direction of the tabletop to expand the length of the tabletop, but cannot be opened in the width direction of the tabletop to expand the width of the tabletop. In this way, when the table is placed in a place with limited length (for example, the length of the space is greater than the length of the tabletop, but less than the sum of the lengths of the tabletop and the extension board), the extension board will be limited by the space and cannot be rotated and opened. Utility Model Content

[0005] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a table with an extendable desktop that can expand the length or width of the desktop.

[0006] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a table with an extendable table top, comprising a table top, table legs arranged under the table top, and an extension plate for extending the table top, the table top is respectively provided with a first connecting mechanism at the right and front positions thereof, a second connecting mechanism is provided at the side wall of the extension plate, and the second connecting mechanism of the extension plate can be detachably connected to any first connecting mechanism of the table top.

[0007] In the above scheme, by respectively providing the first connecting mechanism at the right and front positions of the desktop, when the table is placed in a place with limited length space (for example, the length of the space is greater than the length of the desktop, but less than the sum of the lengths of the desktop and the extension plate), the second connecting mechanism of the extension plate can be connected to the first connecting mechanism at the front position of the desktop, so that the width of the desktop can be expanded. When the table is placed in a place with limited width space, the second connecting mechanism of the extension plate can be connected to the first connecting mechanism at the right position of the desktop, so that the length of the desktop can be expanded, so that the extension plate will not be restricted by space and cannot be used. When used in a place with sufficient length and width space, the user can choose to expand the length or width of the desktop according to personal preference, and the use will be more flexible. In addition, when the extension plate is not needed, the extension plate can be disassembled from the desktop to restore the original area of ​​the desktop and save the space occupied by the table.

[0008] In order to realize the structural function that the second connection mechanism of the extension plate can be detachably connected to any first connection mechanism of the desktop, the first connection mechanism is a through hole provided on the desktop, and the second connection mechanism includes an insert block provided on the side wall of the extension plate, and the insert block is connected to the extension plate through the connecting block. When in use, the insert block is passed through the through hole and abutted against the bottom of the desktop. At this time, the connecting block is located in the through hole, and the extension plate abuts against the top of the desktop and extends out of the outside of the desktop, thereby completing the connection between the extension plate and the desktop, so that the area of ​​the desktop can be expanded. Among them, under the effect of the insert block abutting against the bottom of the desktop and the extension plate abutting against the top of the desktop, the extension plate can be effectively prevented from falling down during use, thereby ensuring the assembly stability of the extension plate. By pulling out the extension plate so that the insert block is out of the through hole, the extension plate can be disassembled from the desktop, and the disassembly and assembly operation is convenient and fast.

[0009] Furthermore, the above-mentioned plug block is parallel to the extension plate, and the connecting block is an inclined structure, so that the plug block can be easily passed through the through hole and abutted against the bottom of the desktop, while ensuring that the extension plate is parallel to the desktop, which is more convenient to use. In addition, the bottom of the above-mentioned extension plate is bent downward corresponding to the edge of the desktop, so that when the extension plate is assembled with the table, the bend of the extension plate will abut against the edge of the desktop, and under the effect of the connecting block abutting against the side wall of the through hole, the extension plate can be prevented from moving left and right relative to the desktop, further improving the assembly stability of the extension plate.

[0010] Further, the above-mentioned extension plates have two, and through holes are also respectively provided at the left and rear positions of the desktop. By arranging two extension plates, the area of ​​the desktop can be further expanded.

[0011] Furthermore, the table has two legs, which are rotatably connected to the two end positions under the tabletop, so that the two legs can be rotated to open and fold relative to the bottom of the tabletop. When the table is not in use, the two legs can be folded up to reduce the size of the table, making it easier to carry and store the table.

[0012] Furthermore, the bottom of the table legs is provided with anti-skid rubber sleeves, which prevent the bottom of the table legs from sliding relative to the ground, thereby improving the supporting stability of the table legs on the table top, making the table more stable when placed and used.

[0013] Furthermore, the table top comprises a left plate body and a right plate body that are hinged to each other, and two table legs are rotatably connected to the outer ends of the lower sides of the plates on the corresponding sides, and when the two table legs are rotated to a folded state, the two plates can be rotated to fold and unfold each other. When the table is not in use, the two table legs can be folded up first, and then the two plates can be folded up together, so that the volume of the table can be further reduced, and it will be more convenient to carry and store.

[0014] In order to realize the structural function that the above-mentioned two plates can rotate, fold and open relative to each other, the above-mentioned left plate body includes a left top plate and a left side plate respectively arranged at the front and rear sides below the left top plate, and the right plate body includes a right top plate and a right side plate respectively arranged at the front and rear sides below the right top plate, the inner ends of the two left sides are respectively provided with a first connecting piece, and the inner ends of the two right sides are respectively provided with a second connecting piece, the first connecting piece is hinged with the second connecting piece through a pin shaft, and the first connecting piece and the second connecting piece can rotate relative to each other around the pin shaft, so that the left plate body and the right plate body can be respectively rotated around the pin shaft to open and fold through their respective connecting pieces.

[0015] Furthermore, a notch is provided at the inner end of the left side plate, which matches the side wall of the second connecting plate. When the left plate body and the right plate body are rotated to the open state, the side wall of the second connecting plate cooperates with the notch, which can prevent the two plate bodies from excessively rotating in the opening direction, thereby ensuring the structural stability of the two plate bodies in the open state.

[0016] Furthermore, the table legs include two vertical rods and a support rod connected to the lower ends of the two vertical rods, and the upper ends of the two vertical rods are rotatably connected to the inner sides of the side panels on the corresponding sides, so that when the table legs are rotated to the folded state, the two vertical rods and the support rod will be located between the corresponding two side panels below the top plate to ensure that the table legs will not hinder the folding of the left and right panels in the folded state. In addition, a stopper is provided on the inner side of all the side panels, and when the table legs are in the open state, the vertical rod abuts against the side wall of the stopper, which can prevent the table legs from excessively rotating in the opening direction and ensure the structural stability of the table legs in the open state.

[0017] The beneficial effects of the table with an extendable desktop of the utility model are:

[0018] 1. The extension board can be connected to any through hole on the desktop. Users can choose to connect the extension board to one of the through holes on the desktop according to the space on the table. In this way, the extension board will not be unable to be used due to space restrictions, thus solving the problem that the existing extension board cannot be opened due to space restrictions. In addition, the insertion block and the extension board are respectively offset against the desktop, which can ensure the stability of the assembly of the extension board and the desktop, and the disassembly and assembly operation is convenient.

[0019] 2. The table legs can be rotated and folded relative to the table top, and the two plates can also be rotated and folded relative to each other, so that the size of the table can be reduced, making it convenient to carry and store.

[0020] 3. The block can ensure the structural stability of the table legs in the open state, and the notch and the second connecting piece can ensure the structural stability of the two plates in the open state, thereby ensuring the opening stability of the table, making the table more convenient and safer to use.

[0033] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0034] Embodiment 1

[0035] like Figure 1-5 As shown, the utility model provides a table with an extendable tabletop, comprising a tabletop 1, table legs 2 arranged under the tabletop 1, and an extension plate 3 for extending the tabletop, the tabletop 1 is provided with a first connecting mechanism at the right and front positions thereof, respectively, and a second connecting mechanism is provided on the side wall of the extension plate, and the second connecting mechanism of the extension plate can be detachably connected to any first connecting mechanism of the tabletop 1.

[0036] Specifically, Figure 5 As shown, the first connection mechanism is a through hole 10 provided on the desktop 1, and the two through holes 10 are respectively located on the desktop 1 near the right side wall and the front side wall thereof. The second connection mechanism comprises an insert block 31 provided on the side wall of the extension plate 3, the insert block 31 is connected to the extension plate 3 through a connecting block 32, and the insert block 31, the connecting block 32 and the extension plate 3 are an integrated structure to ensure the connection stability of the insert block 31, the connecting block 32 and the extension plate 3.

[0037] like Figure 2 , 3 As shown, when the insert block 31 passes through one of the through holes 10 and abuts against the bottom of the desktop 1, the connection block 32 is located in the through hole 10, and the extension plate 3 abuts against the top of the desktop 1 and extends out of the outside of the desktop 1. In this way, the extension plate 3 and the desktop 1 are connected, and the area of ​​the desktop 1 is expanded, thereby achieving the structural function that the second connection mechanism of the extension plate can be detachably connected to any first connection mechanism of the desktop. Among them, under the action of the insert block 31 abutting against the bottom of the desktop 1 and the extension plate 3 abutting against the top of the desktop 1, the extension plate 3 can be effectively prevented from falling down during use, ensuring the assembly stability of the extension plate 3. Figure 5 As shown, by pulling out the extension plate 3 so that the insert block 31 is out of the through hole 10, the extension plate 3 can be removed from the desktop 1, and the disassembly and assembly operation is convenient and fast.

[0038] In addition, the above-mentioned plug block 31 is parallel to the extension plate 3, and the connecting block 32 is an inclined structure, so that the plug block 31 can easily pass through the through hole 10 and abut against the bottom of the desktop 1, and the plug block 31 and the extension plate 3 are parallel to the desktop 1 when assembled with the desktop 1, which is more convenient to use. Figure 3 As shown, the lower side of the extension plate 3 is bent downward at the edge of the table top 1, so that when the extension plate 3 is assembled with the table 1, the bent portion of the extension plate 3 will abut against the edge of the table top 1. In addition, the connecting block 32 abuts against the side wall of the through hole 10, which can prevent the extension plate 3 from moving left and right relative to the table top 1, thereby further improving the assembly stability of the extension plate 3.

[0039] The table of this embodiment has through holes 10 respectively opened at the right and front positions of the table top 1, so that the extension plate 3 can be connected to the table top through its insert block 31 passing through any through hole 10. Figure 4 As shown, when the table is placed in a space with limited length (for example, the length of the space is greater than the length of the desktop 1, but less than the sum of the lengths of the desktop 1 and the extension board 3), the insert block 31 of the extension board 3 can be connected to the desktop 1 through the through hole 10 at the front of the desktop 1, thereby expanding the width of the desktop 1. Figure 1As shown, when the table is placed in a place with limited width (for example, the width of the space is greater than the width of the desktop 1, but less than the sum of the widths of the desktop 1 and the extension board 3), the plug 31 of the extension board 3 can be connected to the desktop 1 through the through hole 10 at the right position of the desktop 1, so that the length of the desktop 1 can be expanded. This is equivalent to the user being able to assemble the extension board 3 in the length or width direction of the table at will, so that the extension board 3 will not be unable to be used due to space restrictions. Even when the table is placed in a place with sufficient length and width, the user can choose to expand the length or width of the desktop 1 according to personal preferences, which is more flexible. In addition, when the extension board 3 is not needed, the extension board 3 can be pulled out and removed from the desktop 1 to restore the original area of ​​the desktop 1 and save the space occupied by the table.

[0040] Embodiment 2

[0041] This embodiment is a further improvement on the structure of the table with an extendable tabletop in the first embodiment. The improvement is as follows: Figure 6 , 7 As shown, the above-mentioned extension plates 3 have two pieces, and through holes 10 are also respectively opened on the left and rear positions of the desktop 1. This embodiment is equivalent to opening four through holes 10 on the desktop 1. The plug-in blocks 31 of the two extension plates 3 can be connected to the desktop 1 through one of the through holes 10 respectively, so that the user can extend the area of ​​the table more freely.

[0042] For example: when the table is placed in a space with a length greater than the sum of the lengths of the tabletop 1 and the two extension boards 3, Figure 6 As shown, the inserting blocks 31 of the two extension boards 3 can be respectively inserted into the through holes 10 located at the left and right positions of the desktop 1 to connect with the desktop 1, so that the length of the desktop 1 can be further extended. When the table is placed in a space with a width greater than the sum of the widths of the desktop 1 and the two extension boards 3, the inserting blocks 31 of the two extension boards 3 can be respectively inserted into the through holes 10 located at the front and rear positions of the desktop 1 to connect with the desktop 1, so that the width of the desktop 1 can be further extended. Of course, as Figure 7 As shown, the user may also choose to insert the insert blocks 31 of the two extension plates 3 into the through holes 10 located at the right and front positions of the desktop 1 to connect with the desktop 1, thereby expanding the length and width of the desktop 1 at the same time. This makes the assembly of the extension plates 3 more flexible and more convenient to use.

[0043] As an improved solution of this embodiment, the table legs 2 are provided with two legs, which are rotatably connected to the two outer end positions below the table top 1, so that the two legs 2 can be rotated, opened and folded relative to the bottom of the table top 1. When the table is needed, the two legs 2 can be rotated and opened, so that the table top 1 is supported by the two legs 2 for use. When the table is not in use, Figure 5 As shown, the two table legs 2 can be folded up, thereby reducing the size of the table and making it easier to carry and store the table.

[0044] In addition, the bottom of the table leg 2 is provided with an anti-skid rubber sleeve 20, which prevents the bottom of the table leg 2 from sliding relative to the ground, thereby improving the supporting stability of the table leg 2 on the table top 1, making the table more stable when placed and used.

[0045] Embodiment 3

[0046] This embodiment is a further improvement on the structure of the table with an extendable tabletop in the second embodiment. The improvement is as follows: Figure 8-10 As shown, the above-mentioned table top 1 includes a left plate body 11 and a right plate body 12 which are hinged to each other, and two table legs 2 are rotatably connected to the outer end portions of the lower sides of the plates on the corresponding sides. When the two table legs 2 are rotated to a folded state, the two plates can be rotated to fold and open each other.

[0047] Specifically, the left plate body 11 includes a left top plate 111 and a left side plate 112 respectively arranged at the front and rear sides below the left top plate 111, and the right plate body 12 includes a right top plate 121 and a right side plate 122 respectively arranged at the front and rear sides below the right top plate 121, the inner ends of the two left side plates 112 are respectively provided with a first connecting piece 1121, the side wall of the first connecting piece 1121 is provided with a connecting rod 1122, the connecting rod 1122 of the first connecting piece 1121 is fixedly connected to the inner side of the left side plate 112 on the corresponding side by a rivet, and the inner ends of the two right side plates 122 are respectively provided with a second connecting piece 1221, the first connecting piece 1121 is provided with a connecting rod 1122, and the connecting rod 1122 of the first connecting piece 1121 is fixedly connected to the inner side of the left side plate 112 on the corresponding side by a rivet. The first connecting piece 1121 and the second connecting piece 1221 are both circular structures, and the first connecting piece 1121 is overlapped on the inner side of the second connecting piece 1221. The first connecting piece 1121 is hinged to the second connecting piece 1221 through the pin 4. The first connecting piece 1121 and the second connecting piece 1221 have the same axis as the pin 4, so that the first connecting piece 1121 and the second connecting piece 1221 can rotate around the pin 4, so that the left plate 11 and the right plate 12 can be rotated around the pin 4 through their respective connecting pieces to open and fold, thereby realizing the structural function that the two plates can rotate, fold and open. Two of the through holes 10 are respectively opened at the left and rear positions of the left top plate 111, and the other two through holes 10 are respectively opened at the right and front positions of the right top plate 121.

[0048] In addition, the table leg 2 includes two vertical rods 21 and a support rod 22 connected to the lower ends of the two vertical rods 21. The middle part of the support rod 22 is bent inward to form a U-shaped groove, so that the left and right ends of the support rod 22 serve as a support part. The anti-slip rubber sleeve 20 is mounted on the support part, so that the support will be more stable. The upper ends of the two vertical rods 21 are respectively rotatably connected to the inner side of the side plate on the corresponding side, so that when the table leg 2 is rotated to the folded state, the two vertical rods 21 and the support rod 22 will be located between the corresponding two side plates under the top plate to ensure that the table leg 2 will not hinder the folding of the left plate body 11 and the right plate body 12 in the folded state.

[0049] When the table of this embodiment is not needed, Fig.10 As shown, the two extension plates 3 can be disassembled first, and then the two table legs 2 can be rotated and folded under the corresponding top plates, and then the two plates can be folded up against each other. At this time, there is a gap between the two table legs 2, so that the two extension plates 3 can be inserted into the gap between the two table legs 2, thereby completing the folding operation of the table. This can further reduce the size of the table, making it more convenient to carry and store.

[0050] As an improvement of this embodiment, Figure 8 , 9 As shown, the inner end of the left side plate 112 is provided with a notch 1120 matching the side wall of the second connecting piece 1221. When the left plate body 11 and the right plate body 12 are rotated to the open state, the side wall of the second connecting piece 1221 cooperates with the notch 1120, which can prevent the two plates from excessively rotating in the opening direction, thereby ensuring the structural stability of the two plates in the open state.

[0051] In addition, a stopper 5 is provided on the inner side of all the above-mentioned side panels. When the table leg 2 is in the open state, the vertical rod 21 abuts against the side wall of the stopper 5. At this time, the stopper 5 can prevent the vertical rod 21 from excessively rotating in the opening direction, thereby ensuring the structural stability of the table leg 2 in the open state.

[0052] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
