Description

Technical Field

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

[0002] Current folding tables consist of a tabletop and hinged, independent legs located near the corners. To ensure overall stability when the legs are extended, a movable support tube is typically installed between the legs and the tabletop. The bottom of the tabletop has two sets of symmetrically positioned, openable elastic retainers. When the legs are extended, the support tube engages with these retainers. With this structure, the support tubes must be manually aligned and inserted into the slots of the elastic retainers, a process that is inconvenient. There is a pressing need for a design that allows for easy insertion of the support tubes without needing to align them with the retainers, enabling convenient insertion during leg extension. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a folding table that solves the problem of inconvenience in inserting the support tube into the slot.

[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0005] A folding table includes a tabletop, a leg assembly, a support tube, a guide tube, and a limiting assembly. The limiting assembly is fixed to the back of the tabletop. The leg assembly and the guide tube are spaced apart on the back of the tabletop and are rotatably connected to the tabletop. The support tube is rotatably connected to the leg assembly and the guide tube, such that when the leg assembly is opened, the support tube is positioned in the limiting assembly under the action of the leg assembly and the guide tube and remains in a fixed position.

[0006] As a preferred embodiment, the foot tube assembly, support tube, and guide tube are linked together, so that when the foot tube assembly is opened and closed, the guide tube is located on both sides of the rotation point of the guide tube and the table.

[0007] As a preferred embodiment, the limiting component includes a limiting knob and a slot block. The slot block has a limiting groove for accommodating the support tube. The limiting knob is rotatably connected to the end face of the slot block, and rotating the limiting knob can cover at least a portion of the limiting groove. By using the limiting knob to cover the limiting groove, the support tube can be prevented from detaching from the limiting groove, thus preventing the folding table from folding accidentally and improving the overall stability of the table.

[0008] As a preferred embodiment, at least one end of the limiting knob is further provided with a raised edge, and a locking groove is further provided on the side wall of the limiting groove. Rotating the limiting knob causes the raised edge to extend into or disengage from the locking groove. The cooperation between the locking groove and the raised edge prevents the support tube from disengaging from the limiting groove, thereby reducing the force on the rotating part of the limiting knob, improving the smoothness of the rotation of the limiting knob, and also extending the service life of the limiting knob.

[0009] As a preferred embodiment, one side wall of the limiting groove is higher than the other side wall, the limiting knob is rotatably disposed on the end face of the lower side, the locking groove is formed in the side wall of the higher side, and the height of the locking groove is flush with the height of the protrusion.

[0010] As a preferred embodiment, the limiting component is located between the rotation point of the foot tube assembly and the tabletop and the rotation point of the guide tube and the tabletop, and is located on one side of the guide tube. The limiting component and the guide tube are offset to avoid interference between the guide tube and the limiting component after the support tube enters the limiting component.

[0011] As a preferred embodiment, the leg tube assembly is U-shaped overall, and the support tube is U-shaped with both sides sloping outwards. The two ends of the support tube are respectively hinged to both sides of the leg tube assembly. Both the leg tube assembly and the support tube adopt a U-shaped structure, which is more robust and stable than a single tubular structure.

[0012] As a preferred embodiment, one end of the guide tube is rotatably connected to the support tube via a sleeve, and the other end is rotatably connected to the table via a support member.

[0013] As a preferred embodiment, the foot tube assembly includes an outer tube and an inner tube, the outer tube being U-shaped, and two inner tubes being inserted into both ends of the outer tube respectively.

[0014] As a preferred embodiment, the outer tube is also provided with a locking element for maintaining the relative position stability of the outer tube and the inner tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The present invention has a support tube connected to a guide tube hinged to the table. The guide tube limits the movement position of the support tube, so that when the foot tube assembly is opened, it can drive the support tube to easily enter the limiting assembly, thus solving the problem of inconvenience in putting the support tube into the limiting assembly (slot).

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] like Figures 1 to 4 As shown, a folding table includes a tabletop 1, a leg assembly 2, a support tube 3, a guide tube 4, and a limiting assembly. The limiting assembly is fixed to the back of the tabletop 1. The leg assembly 2 and the guide tube 4 are spaced apart on the back of the tabletop 1 and are rotatably connected to the tabletop 1. The support tube 3 is rotatably connected to the leg assembly 2 and the guide tube 4, so that when the leg assembly 2 is opened, the support tube 3 is positioned in the limiting assembly under the action of the leg assembly 2 and the guide tube 4 and remains in a fixed position.

[0032] The foot tube assembly 2 is U-shaped, and the support tube 3 is U-shaped with both sides sloping outwards. The two ends of the support tube 3 are respectively hinged to the two sides of the foot tube assembly 2. Both the foot tube assembly and the support tube adopt a U-shaped structure, which is more robust and stable than a single tubular structure.

[0033] The limiting component is located between the hinge point of the foot tube assembly 2 and the tabletop 1 and the hinge point of the guide tube 4 and the tabletop 1. One end of the guide tube 4 is rotatably connected to the support tube 3 through the sleeve 41, and the other end is rotatably connected to the tabletop 1 through the support member 42. The connection between the sleeve 41 and the support tube 3 is located on one side of the limiting component. The limiting component and the guide tube are offset to avoid interference between the guide tube and the limiting component after the support tube enters the limiting component.

[0034] The foot tube assembly, support tube, and guide tube of this utility model form a linkage structure. When the foot tube assembly 2 is opened, the support tube 3 and guide tube 4 are linked. The support tube 3 is located on one side of the rotation point between the guide tube 4 and the table 1, and the support tube 3 is placed into the limiting assembly according to the rotation trajectory of the guide tube 4. When the foot tube assembly 2 is closed, the support tube 3 and guide tube 4 are linked. According to the rotation trajectory of the guide tube 4, the support tube 3 rotates to the other side of the rotation point between the guide tube 4 and the table 1, and the foot tube assembly 2, support tube 3, and guide tube 4 are all in close contact with the table 1.

[0035] like Figure 5 As shown, the limiting component includes a limiting knob 5 and a slot block 6. The slot block 6 is fixed to the tabletop 1, and the fixing method can be glue bonding, bolt fixing, etc. The slot block 6 has a limiting groove 61 for accommodating the support tube 3. The limiting knob 5 is rotatably connected to the end face of the slot block 6, and rotating the limiting knob 5 can cover at least part of the limiting groove 61. The above structure uses the limiting knob to cover the limiting groove, which can prevent the support tube from detaching from the limiting groove, prevent the folding table from folding accidentally, and improve the overall stability of the table.

[0036] At least one end of the limiting knob 5 is provided with a protruding edge 51, and a locking groove 62 is also provided on the side wall of the limiting groove 61. Rotating the limiting knob 5 causes the protruding edge 51 to extend into or disengage from the locking groove 62. The two side walls of the limiting groove 61 can be at the same height, which requires the protruding edge 51 structure to be set at the lower part of the limiting knob, or the limiting knob to be designed as a bent shape. The cooperation between the locking groove 62 and the protruding edge 51 prevents the support tube from disengaging from the limiting groove 61, thereby reducing the force on the rotating part of the limiting knob 5, improving the smoothness of the rotation of the limiting knob 5, and also extending the service life of the limiting knob.

[0037] In this embodiment, one sidewall of the limiting groove 61 is higher than the other sidewall. The limiting knob 5 is rotatably mounted on the lower side end face, and the locking groove 62 is formed in the higher sidewall, with its height flush with the height of the protruding edge 51. This allows the protruding edge 51 of the limiting knob 5 to extend directly from the side, resulting in a simpler structure and easier manufacturing. Furthermore, when the limiting knob 5 locks the support tube 3 in the limiting groove 61, the gap between the limiting knob 5 and the support tube 3 is smaller, providing more stable support.

[0038] The side of the limiting knob 5 is also provided with multiple anti-slip protrusions 52 at longitudinal intervals. The above structure increases the contact area between the finger and the knob when operating the knob, avoids finger slippage, and improves the convenience of operation.

[0039] The foot tube assembly includes an outer tube 21 and an inner tube 22. The outer tube 21 is U-shaped, and two inner tubes 22 are respectively inserted into both ends of the outer tube 21. The outer tube 21 is also provided with a locking member 23 for maintaining the relative position stability of the outer tube 21 and the inner tube 22. One end of the inner tube 22 is also provided with a freely rotatable foot pad 24.

[0040] The leg assembly features a telescopic structure, allowing for adjustment of the overall height of the folding table to meet different needs. In addition, the freely rotating corner pads on the leg assembly enable the folding table to be used not only on flat ground but also on various uneven surfaces, making its usage scenarios more diverse.

[0041] The operation process of this utility model is as follows:

[0042] When opened, pull the leg tube assembly, and the support tube and guide tube will move together. The support tube will be supported in the limiting groove of the limiting assembly according to the rotation trajectory of the guide tube. Rotate the limiting knob to lock the protruding edge of the limiting knob in the locking groove, thus completing the stable support of the table.

[0043] When retracting, rotate the limiting knob to disengage the protrusion from the locking groove, and rotate it to a position where the limiting knob does not obstruct the limiting groove (in this embodiment, when the limiting knob is parallel to the limiting groove, the support tube can freely enter and exit the limiting groove), fold the foot tube assembly inward, link the support tube and guide tube, and the foot tube is in close contact with the table. At the same time, the support tube and the rotating component are in close contact with the table according to the linkage trajectory.

[0044] This invention utilizes a linkage structure between the support tube and the guide tube, allowing the support tube to be placed inside the limiting component without directly facing it. Simply retracting the foot tube assembly activates the linkage between the support tube and the guide tube, thus placing the support tube into the limiting component. The entire process is simple, convenient, and more stable.
