Description

Technical Field

[0001] This utility model relates to the field of wall-mounted folding table technology, and in particular to a retractable wall-mounted folding table. Background Technology

[0002] The wall-mounted folding table is installed on the wall and can be folded. It consists of a tabletop that is connected to the wall by hinges, a fixed rod that is fixed to the wall, a rotating rod, table legs, and a connecting rod assembly. When storing the wall-mounted folding table, the user rotates the table legs, causing the first and second connecting rods to rotate, so that the table legs fit against the bottom of the tabletop. Then, the tabletop is rotated to rest against the wall. Next, the rotating rod on the fixed rod is rotated, so that the rotating rod fits against the tabletop and limits the tabletop, thus completing the folding and storage of the wall-mounted folding table.

[0003] The inventor discovered in his daily work that when using a wall-mounted folding table, because the tabletop has a fixed area, if the user needs to place more items that are larger than the tabletop, the tabletop may not be able to properly accommodate the user's items. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that, in actual use, when the tabletop has a fixed usable area, and the user needs to place more items larger than the tabletop, the tabletop may not be able to properly accommodate the user's items. Therefore, this utility model proposes a foldable wall-mounted table.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a retractable wall-mounted folding table, comprising a tabletop rotatably connected to a wall via hinges and a fixing rod fixedly connected to the wall. An extension assembly is provided on one side of the tabletop, table legs are rotatably connected to the lower end of the tabletop, a rotating rod is rotatably connected to the other end of the fixing rod, a first connecting rod is rotatably connected to the left end of the table legs, and a second connecting rod is rotatably connected to the lower end of the tabletop. The first and second connecting rods are rotatably connected via a pivot. The extension assembly includes extension plates slidably inserted at both ends of the tabletop. A fixing mechanism for fixing the extension plates is provided on the front of the tabletop, and a transmission mechanism is provided between the two extension plates.

[0006] The effect achieved by the above components is as follows: by setting up the extension components, when expanding the usable area of ​​the tabletop, one side of the extension plate is dragged, and with the help of the transmission mechanism, the one side of the extension plate is expanded outward. Then, the extension plate is fixed by the fixing mechanism, thereby maximizing the effect of expanding the usable area of ​​the tabletop.

[0007] Preferably, the fixing mechanism includes a rod that is slidably inserted into the front of the tabletop, and one end of the extension plate has a plurality of evenly distributed positioning grooves, the inner wall of which is provided with protrusions.

[0008] The effect achieved by the above components is: dragging the insertion rod causes it to be inserted into the positioning slot, thereby fixing the expansion plate.

[0009] Preferably, a magnetic sheet is fixedly connected to the front of the tabletop, and the magnetic sheet is used to attract the insertion rod.

[0010] The effect achieved by the above components is that the insertion rod is attracted by the magnetic sheet, thereby limiting the insertion rod's position.

[0011] Preferably, the transmission mechanism includes a rack fixedly connected to one side of the extension plate, the rack being inserted into the other side of the extension plate.

[0012] The effect achieved by the above components is as follows: dragging one side of the expansion plate causes the rack to move accordingly, and through the drive mechanism, the rack on the other side moves, causing the other side of the expansion plate to expand.

[0013] Preferably, the inner wall of the tabletop is rotatably connected to a gear, which meshes with a rack.

[0014] The effect achieved by the above components is as follows: dragging one side of the expansion plate causes the rack to move, which in turn causes the gear to rotate, causing the rack on the other side to move, and causing the other side of the expansion plate to expand outward.

[0015] Preferably, one end of the insertion rod is fixedly connected to a limiting rope, and the other end of the limiting rope is fixed to the table.

[0016] The effect achieved by the above components is to limit the insertion rod by setting a limiting rope.

[0017] Preferably, a pin is slidably inserted into the front of the second connecting rod, the pin being inserted into the first connecting rod, and the surface of the pin is provided with protrusions.

[0018] The effect achieved by the above components is: dragging the pin causes it to insert into the first connecting rod, thereby fixing the first connecting rod and the second connecting rod.

[0019] Preferably, one end of the pin is fixedly connected to a spring, and the other end of the spring is fixedly connected to the second connecting rod.

[0020] The effect achieved by the above components is that by setting a spring, the pin is pulled, thereby providing auxiliary limiting of the pin.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting an extension component, when expanding the usable area of ​​the tabletop, one side of the extension plate is dragged and extended outward with the help of a transmission mechanism. Then, the extension plate is fixed by a fixing mechanism, thereby maximizing the expansion of the usable area of ​​the tabletop. However, since the usable area of ​​the tabletop is fixed, when the user needs to place more items larger than the tabletop, the tabletop may not be able to properly accommodate the user's items.

[0028] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a retractable wall-mounted folding table includes a tabletop 1 rotatably connected to the wall via a hinge 5 and a fixing rod 3 fixedly connected to the wall. An extension component 2 is provided on one side of the tabletop 1, a table leg 6 is rotatably connected to the lower end of the tabletop 1, a rotating rod 4 is rotatably connected to the other end of the fixing rod 3, a first connecting rod 7 is rotatably connected to the left end of the table leg 6, and a second connecting rod 8 is rotatably connected to the lower end of the tabletop 1. The first connecting rod 7 and the second connecting rod 8 are rotatably connected by a pivot.

[0029] Reference Figure 2 and Figure 3 as well as Figure 4As shown in this embodiment: the expansion component 2 includes expansion plates 21 slidably inserted at both ends of the tabletop 1. A fixing mechanism 22 for fixing the expansion plates 21 is provided on the front of the tabletop 1. A transmission mechanism 25 is provided between the two expansion plates 21. By setting the expansion component 2, when expanding the usable area of ​​the tabletop 1, dragging one side of the expansion plate 21, with the help of the transmission mechanism 25, causes one side of the expansion plate 21 to expand outwards. Then, the fixing mechanism 22 is used to fix the expansion plate 21, thereby maximizing the expansion of the usable area of ​​the tabletop 1. The fixing mechanism 22 includes a rod 221 slidably inserted on the front of the tabletop 1. One end of the expansion plate 21 has multiple evenly distributed positioning grooves 222. The inner wall of the positioning grooves 222 has protrusions. Dragging the rod 221 causes the rod 221 to insert into the positioning grooves 222, thereby fixing the expansion plate 21. A magnetic sheet 23 is fixedly connected to the front of the tabletop 1. 3. A magnetic sheet 23 is used to attract the insertion rod 221. The insertion rod 221 is attracted by the magnetic sheet 23, and then the insertion rod 221 is limited. The transmission mechanism 25 includes a rack 251 fixedly connected to one side of the expansion plate 21. The rack 251 is inserted into the other side of the expansion plate 21. Dragging one side of the expansion plate 21 causes the rack 251 to move. Through the drive mechanism, the rack 251 on the other side moves, causing the other side of the expansion plate 21 to expand. A gear 252 is rotatably connected to the inner wall of the table 1. The gear 252 and the rack 251 are meshed. Dragging one side of the expansion plate 21 causes the rack 251 to move. The gear 252 rotates, causing the rack 251 on the other side to move, causing the other side of the expansion plate 21 to expand outward. One end of the insertion rod 221 is fixedly connected to a limiting rope 24. The other end of the limiting rope 24 is fixed to the table 1. The insertion rod 221 is limited by the limiting rope 24.

[0030] Reference Figure 2 As shown in this embodiment: a pin 9 is slidably inserted into the front of the second connecting rod 8. The pin 9 is inserted into the first connecting rod 7. The surface of the pin 9 is provided with a protrusion. Dragging the pin 9 causes it to be inserted into the first connecting rod 7, thereby fixing the first connecting rod 7 and the second connecting rod 8. One end of the pin 9 is fixedly connected to a spring 10, and the other end of the spring 10 is fixedly connected to the second connecting rod 8. By setting the spring 10, the pin 9 is pulled, thereby providing auxiliary limiting for the pin 9.

[0031] Working principle:

[0032] When folding the wall-mounted folding table, the user rotates the table leg 6, causing the first connecting rod 7 and the second connecting rod 8 to rotate, so that the table leg 6 fits against the bottom of the tabletop 1. Then, the tabletop 1 is rotated to lean against the wall. Next, the rotating rod 4 on the fixing rod 3 is rotated, so that the rotating rod 4 fits against the tabletop 1 and limits the tabletop 1, thus completing the folding and storage of the wall-mounted folding table. When expanding the usable area of ​​the tabletop 1, one side of the expansion plate 21 is dragged, causing the rack 251 to move accordingly, causing the gear 252 to rotate, causing the rack 251 on the other side to move, and causing the other side of the expansion plate 21 to move outward. Next, drag the insertion rod 221 so that it is inserted into the positioning groove 222, thereby fixing the expansion plate 21 and maximizing the expansion of the usable area of ​​the tabletop 1. By setting the magnetic sheet 23, the insertion rod 221 is attracted and limited. By setting the limiting rope 24, the insertion rod 221 is limited. Dragging the pin 9 so that it is inserted into the first connecting rod 7, thereby fixing the first connecting rod 7 and the second connecting rod 8. By setting the spring 10, the pin 9 is pulled and thus the pin 9 is further limited.
