Description

Technical Field

[0001] This utility model relates to a folding table. Background Technology

[0002] Tables are a common piece of furniture in people's lives, indispensable in homes, leisure spaces, and offices. Currently, table sales are inseparable from packaging and transportation issues. While a model of pre-assembling and then packaging for transport avoids the hassle of users assembling themselves or hiring professionals, it presents problems such as excessive packaging volume, wasted storage space, susceptibility to damage during transport, and high transportation costs. A sales model of disassembling and packaging for transport, followed by reassembly at the destination, requires tables to be easy to assemble, ideally tool-free; otherwise, it will cause assembly difficulties for end users, potentially impacting sales. Furthermore, most current folding table support and locking structures are tilted, placing greater stress on the support and making them prone to damage, affecting structural stability. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a folding table with good structural stability when unfolded.

[0004] This utility model is achieved through the following technical solution:

[0005] A folding table includes a support frame that mates with a tabletop. The support frame has matching sliding grooves on both its front and rear sides. It also includes a connecting tube, both ends of which can be placed within the sliding groove on the same side. A support leg is connected to the bottom of the connecting tube. Furthermore, it includes a connecting rod, one end of which is hinged to a connecting part on one side of the support frame, and the other end of which is hinged to a connecting sleeve. The connecting sleeve is fitted around the outer periphery of the connecting tube. Rotation of the support leg relative to the support frame allows the connecting tube to move and rotate within the sliding groove. The connecting tube can slide and rotate relative to the connecting sleeve, thereby changing the distance between the connecting tube and the connecting part.

[0006] In this embodiment of the utility model, a locking mechanism that can be placed inside the connecting tube is also included. The locking mechanism includes a cooperating spring and a protruding post. The connecting tube is provided with a through hole, and the connecting sleeve is provided with a slot. The protruding post can be connected to the through hole. When the slot is aligned with the through hole, the protruding post can be inserted into the slot so that the folding table remains in the unfolded state.

[0007] In this embodiment of the utility model, a connecting rod is also included. One end of the connecting rod is hinged to the bracket, and the other end of the connecting rod can be hinged to the support leg.

[0008] In this embodiment of the utility model, the slide groove is horizontally arranged on the support, and the connecting rod can swing horizontally relative to the support to realize the horizontal displacement of the connecting pipe.

[0009] In this embodiment of the utility model, the support includes a first support and a second support located on both sides thereon. The first support can rotate relative to the second support. A self-locking mechanism is provided between the first support and the second support, which prevents the first support and the second support from rotating relative to each other when the table is unfolded.

[0010] In this embodiment of the utility model, the self-locking mechanism includes a first connecting member and a second connecting member that can rotate relative to each other. The first bracket can be connected to the first connecting member, and the second bracket can be connected to the second connecting member. The first connecting member is provided with an arc-shaped groove, and one end of the arc-shaped groove is provided with an enlarged hole. It also includes a button that can be pressed and moved. The button is provided with a first connecting part and a second connecting part along its axial direction. The diameter of the first connecting part is larger than the diameter of the second connecting part. When the first connecting member and the second connecting member are unfolded, the first connecting part can be engaged in the enlarged hole, so that the first connecting member and the second connecting member cannot rotate relative to each other. When the button is pressed and the second connecting part is placed in the enlarged hole, the second connecting part can move along the arc-shaped groove, so that the first connecting member and the second connecting member can rotate relative to each other.

[0011] In this embodiment of the utility model, a fixing seat is provided at the second connecting member, and a reset spring is provided between the fixing seat and the button. When the button is located in the enlarged hole, the reset spring can drive the button to move so that the first connecting part is placed in the enlarged hole.

[0012] In this embodiment of the utility model, the second connector is provided with a connecting hole, which can be adapted to the outer periphery of the first connector. The button is provided with a protruding ring, the first connector is located between the protruding ring and the second connector, and the protruding ring can abut against the side wall of the second connector on the periphery of the connecting hole.

[0013] In this embodiment of the utility model, one end of the spring abuts against the fixed base, and the other end of the spring abuts against the protruding ring. The first connecting member and the second connecting member are connected to the fixed rod by bolts.

[0014] This utility model discloses a folding table with the following advantages: when the two tabletops are unfolded, they can self-lock to prevent bending. At the same time, when unfolded, the force direction of the support legs is lateral, ensuring the stability of the tabletop and improving the service life of the joint between the table legs and the tabletops. The self-locking can only be released by pressing a button, allowing the two connecting parts to rotate relative to each other. Combined with the unlocking of the telescopic rod, the table can be folded up. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Referring to the accompanying drawings, a folding table includes a support 300 that mates with a tabletop 400. The support has matching sliding grooves 310 on both sides, front and back. It also includes a connecting tube 50, with both ends positioned within the same sliding groove. A support leg 51 is connected below the connecting tube, forming a folding assembly with the supporting leg. The positions on both sides of the sliding groove can be the limit positions for the supporting leg when folded or unfolded, providing a limiting function. The table also includes a connecting rod 60, one end of which is hinged to a connecting part 320 on one side of the support, and the other end of which is hinged to a connecting sleeve 61. The connecting sleeve is fitted around the connecting tube and can slide around the connecting tube. Rotation of the supporting leg relative to the support allows the connecting tube to move and rotate within the sliding groove. The connecting tube can slide and rotate relative to the connecting sleeve, changing the distance between the connecting tube and the connecting part, thereby enabling the supporting leg to fold or unfold.

[0032] Preferably, it also includes a locking mechanism 70 that can be placed inside the connecting tube. The locking mechanism includes a cooperating spring piece 71 and a protrusion 72. The connecting tube is provided with a through hole 52, and the connecting sleeve is provided with a slot 62. The protrusion can be connected to the through hole. When the slot and the through hole are aligned, that is, when the slot and the through hole are on the same axis of the protrusion by rotation and movement, the protrusion can be inserted into the slot to keep the folding table in the unfolded state. A button 63 can also be added. By pressing the button, the protrusion is disengaged from the slot, and the folding table is folded up.

[0033] Furthermore, it also includes a connecting rod 53, one end of which is hinged to the bracket, and the other end of which can be hinged to the support leg.

[0034] In one embodiment of this invention, the slide groove is horizontally arranged on the support, and the connecting rod can swing horizontally relative to the support to achieve lateral displacement of the connecting pipe. This changes the force of the original locking mechanism from tilting to lateral, effectively improving the stability and lifespan of the overall structure.

[0035] This utility model can be applied to a structure of a single support or multiple small supports forming a large support. When used in a combined support, the support includes a first support 100 and a second support 200 located on both sides. The first support can rotate relative to the second support. A fixing rod is set at the connection between the first support and the second support. A self-locking mechanism 500 is provided between the first support and the second support. The self-locking mechanism prevents the first support and the second support from rotating relative to each other when the table is unfolded.

[0036] Furthermore, the self-locking mechanism includes a first connecting member 10 and a second connecting member 20 that can rotate relative to each other. The first connecting member is provided with an arc-shaped groove 11, and one end of the arc-shaped groove is provided with an enlarged hole 12, the size of which is larger than that of the arc-shaped groove. It also includes a button 30 that can be pressed and moved. The button has a first connecting portion 31 and a second connecting portion 32 arranged axially. The diameter of the first connecting portion is larger than that of the second connecting portion, so that the first connecting portion cannot be placed in the arc-shaped groove, while the second connecting portion can be adapted to the arc-shaped groove. This allows the two connecting members to rotate relative to each other only when needed. The second connecting part can be placed in the arc-shaped groove, allowing it to move within the groove. When the first and second connecting parts are unfolded, i.e., when the table is unfolded, with both connecting parts at 180°, the first connecting part can engage in the enlarged hole. At this time, because the first connecting part cannot be placed in the arc-shaped groove, the first and second connecting parts cannot rotate relative to each other. When the button is pressed to place the second connecting part in the enlarged hole, the second connecting part can move along the arc-shaped groove, allowing the first and second connecting parts to rotate relative to each other, thus folding the table.

[0037] Preferably, a fixing seat 40 is provided at the second connector, and a return spring 41 is provided between the fixing seat and the button. When the button is in the enlarged hole, the return spring can drive the button to move, so that the first connector is placed in the enlarged hole, and at the same time maintain this state so that the first connector and the second connector cannot rotate relative to each other.

[0038] Furthermore, the second connector is provided with a connecting hole 21, which can be adapted to the outer periphery of the first connector. The button is provided with a protruding ring 33, and the first connector is located between the protruding ring and the second connector. The protruding ring can abut against the side wall of the second connector around the connecting hole, thus ensuring that the first connector is always within the connecting hole and preventing the button from detaching from the two connectors. One end of the spring abuts against the fixed base, and the other end of the spring abuts against the protruding ring. The first connector and the second connector are connected to the fixing rod 43 by bolts 42.

[0039] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge.
