Description

Technical Field

[0001] This utility model relates to the technical field of folding tables, and in particular to a locking structure for folding tables. Background Technology

[0002] Egg roll tables and folding tables are a type of table that is easy to carry and use outdoors. In the existing technology, the tabletop of the egg roll table can be rolled up and folded. There are blocks on the lower surface of the four corners of the tabletop, and the upper surface of the frame has slots. The blocks are fastened into the slots, thereby realizing the detachable connection between the tabletop and the frame.

[0003] However, because the locking blocks are inserted into the slots from top to bottom, when fastening the tabletop to the bracket, it is necessary not only to lift the tabletop but also to align the locking blocks with the slots. This makes it inconvenient to quickly fix the tabletop to the bracket, affecting its use. This needs to be improved. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing egg roll tables, which use clips and slots to fix the tabletop to the support, making it inconvenient to quickly install the tabletop onto the support. It provides a new locking structure for folding tables.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A locking structure for a folding table includes a tabletop and a support located below the tabletop, as well as several buckles rotatably disposed on the edge of the tabletop and locking pins disposed on the support. The buckles are provided with locking holes. The buckles rotate along the height direction toward or away from the locking pins. The ends of the locking pins protrude from the locking holes and abut against the bottom wall of the locking holes or retract from the locking holes.

[0007] Rotating the buckle towards or away from the locking post allows the buckle to be fitted onto or detached from the locking post, enabling quick and easy unlocking or locking of the tabletop or bracket. Because the locking post is pressed against the bottom of the locking hole and its end protrudes from the locking hole, it is difficult for the locking post to detach from the buckle when the buckle swings, thus improving the stability of the connection and locking of the tabletop or bracket by the locking post and buckle.

[0008] Preferably, in the above-described locking structure for a folding table, the locking post is slidably mounted on the support, and the locking post moves toward or away from the support.

[0009] When the buckle is fitted onto the locking post, the locking post can be retracted inward first, and then the locking post can be made to pass through the locking hole after the buckle is rotated into place, thereby further improving the smoothness of the buckle being fitted onto the outside of the locking post.

[0010] Preferably, the above-described locking structure for a folding table further includes a return spring and a fixing tube. The bracket includes a hollow horizontal tube and a connector inserted into the end of the horizontal tube. The fixing tube is located inside the horizontal tube and is detachably connected to the connector. One end of the return spring is located inside the fixing tube and abuts against the end wall of the fixing tube. The other end of the return spring abuts against the locking pin. The return spring pushes the end of the locking pin through the connector.

[0011] The connector, fixing tube, and horizontal tube are detachably connected, which facilitates the assembly of the locking pin and the return spring. Since one end of the return spring is inserted into the fixing tube, the extension and retraction direction of the return spring can be restricted by the fixing tube, thereby improving the accuracy of the return spring in pushing the locking pin to return outward.

[0012] As a preferred embodiment, in the above-described locking structure for a folding table, the outer surface of the fixing tube is provided with an anti-detachment protrusion, the inner wall of the connector is provided with an anti-detachment groove, one end of the fixing tube is inserted into the connector for a plug-in fit, and the anti-detachment protrusion is snapped into the anti-detachment groove.

[0013] The anti-loosening protrusions and anti-loosening grooves work together to increase the tightness and stability of the connection between the fixing tube and the connector, preventing the fixing tube from loosening and allowing the return spring to effectively push the locking pin outward.

[0014] Preferably, the above-described locking structure for a folding table further includes a hook, and the buckle plate is provided with a fixing hole. One end of the hook is fastened to the fixing hole and pulls the buckle plate to rotate towards the locking post.

[0015] The hooks allow the buckle plate to be pulled closer to the locking pin, further improving the stability of the connection between the locking pin and the buckle plate and preventing the locking pin from coming out of the locking hole. The hooks can also be used with nets or other containers to store items, and the fixing holes also provide users with a place to hang items, making it easier for users to place items and improving the overall practicality.

[0016] Preferably, in the above-described locking structure for a folding table, the latch plate includes an upper part and a lower part, the locking hole and fixing hole are distributed on the lower part, the upper part is rotatably connected to the edge of the tabletop, and the width of the upper part is smaller than the width of the lower part.

[0017] The upper part is narrower than the lower part, which gives the panel an L-shaped structure and improves its structural strength.

[0018] Preferably, the above-described locking structure for a folding table further includes a pivot rod with through holes at the top. Both ends of the pivot rod pass through the through holes and are mounted on the tabletop. The buckle plate rotates around the pivot rod along the height direction.

[0019] The buckle plate is rotatably mounted on the tabletop through the cooperation of the rotating shaft and the through hole, which has the advantages of simple structure and easy assembly.

[0020] Preferably, in the above-described locking structure for a folding table, a limiting groove is provided on the tabletop, the pivot rod is disposed in the limiting groove, and when the locking pin is inserted into the locking hole, the outer surface of the buckle plate is flush with the outer wall of the tabletop.

[0021] The limiting groove allows the buckle to be embedded in the tabletop, preventing the buckle from protruding out of the tabletop and improving the overall aesthetic effect. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0028] like Figures 1-4 As shown, a locking structure for a folding table includes a tabletop 1 and a support 2, as well as several buckle plates 3 rotatably disposed on the edge of the tabletop 1 and locking pins 4 disposed on the support 2. The buckle plates 3 are provided with locking holes 31. The buckle plates 3 rotate along the height direction towards or away from the locking pins 4. The end of the locking pin 4 passes through the locking hole 31 and abuts against the bottom wall of the locking hole 31 or exits from the locking hole 31.

[0029] Preferably, the locking post 4 is slidably disposed on the bracket 2, and the locking post 4 moves toward or away from the bracket 2.

[0030] Preferably, the bracket also includes a return spring 5 and a fixing tube 6. The bracket 2 includes a hollow horizontal tube 21 and a connector 22 inserted into the end of the horizontal tube 21. The fixing tube 6 is located inside the horizontal tube 21 and is detachably connected to the connector 22. One end of the return spring 5 is located inside the fixing tube 6 and abuts against the end wall of the fixing tube 6. The other end of the return spring 5 abuts against the locking post 4. The return spring 5 pushes the end of the locking post 4 to pass through the connector 22.

[0031] Preferably, the outer surface of the fixing tube 6 is provided with an anti-detachment protrusion 61, and the inner wall of the connector 22 is provided with an anti-detachment groove 221. One end of the fixing tube 6 is inserted into the connector 22 for insertion and engagement, and the anti-detachment protrusion 61 is inserted into the anti-detachment groove 221.

[0032] Preferably, the buckle plate 3 also includes a hook 7, and a fixing hole 32 is provided on the buckle plate 3. One end of the hook 7 is fastened to the fixing hole 32 and pulls the buckle plate 3 to rotate towards the locking post 4.

[0033] Specifically, in actual use, users can hang items through the fixing hole 32, and the other end of the hook 7 can be fastened to the bracket 2 or the lower surface of the tabletop 1. The multiple hooks 7 located around the tabletop 1 can also be used with a net to suspend the net on the lower surface of the tabletop 1, allowing users to place items on the net and also pull the hook 7 towards the locking post 4 through the net.

[0034] Preferably, the buckle plate 3 includes an upper part 33 and a lower part 34, the locking hole 31 and the fixing hole 32 are distributed on the lower part 34, the upper part 33 is rotatably connected to the edge of the tabletop 1, and the width of the upper part 33 is smaller than the width of the lower part 34.

[0035] Preferably, it also includes a pivot rod 8, the upper part 33 has a through hole 331, both ends of the pivot rod 8 pass through the through hole 331 and are set on the table 1, and the buckle plate 3 rotates around the pivot rod 8 in the height direction.

[0036] Preferably, the tabletop 1 has a limiting groove 11, the rotating shaft 8 is disposed in the limiting groove 11, and when the locking pin 4 is inserted into the locking hole 31, the outer surface of the buckle plate 3 is flush with the outer wall of the tabletop 1.

[0037] Specifically, such as Figure 1 , Figure 2 As shown in the embodiment of this application, the horizontal tube 21 extends along the length direction of the tabletop 1. There are two horizontal tubes 21, which are distributed along the width direction of the tabletop 1 on the lower surface of the tabletop 1 near the edge. Connectors 22 are plugged into both ends of the horizontal tube 21.

[0038] like Figure 2 , Figure 3 As shown, the edge of the tabletop 1 is bent downwards and rolled up to form a U-shaped connecting tube. A limiting groove 11 extending inwards from the edge of the tabletop 1 is provided. The rotating shaft 8 passes through the limiting groove 11, and both ends of the rotating shaft 8 are clamped in the connecting tube. Because the connecting tube is U-shaped, the position of the rotating shaft 8 clamped in the connecting tube can be observed, so as to center and fix the rotating shaft 8.

[0039] The upper part 33 of the buckle plate 3 is fitted onto the rotating shaft 8 through the through hole 331. The buckle plate 3 rotates around the rotating shaft 8 along the height direction. In its natural state, the buckle plate 3 stands vertically and the outer surface of the buckle plate 3 is flush with the edge of the table board 1.

[0040] The buckle plate 3 is a long plate structure. The locking hole 31 and the fixing hole 32 are distributed from top to bottom. The inner diameter of the locking hole 31 is slightly larger than the outer diameter of the locking pin 4. The outer end of the locking pin 4 has rounded corners, which can reduce the obstruction encountered by the locking pin 4 when it passes through the locking hole 31.

[0041] like Figure 3 , Figure 4 As shown, in this application, the locking post 4 can be directly fixed to the end of the connector 22, or it can be slidably disposed in the horizontal tube 21 and pass out of the connector 22 through the return spring 5.

[0042] When the locking pin 4 is immovable and the tabletop 1 needs to be fixed to the bracket 2, simply rotate the buckle plate 3 towards the locking pin 4 until it is placed vertically. This allows the end of the locking pin 4 to pass directly through the locking hole 31 and press against the bottom of the locking hole 31. Thus, the bracket 2 and the tabletop 1 can be fixed by the cooperation of the buckle plate 3 at the four corners and the locking pin 4.

[0043] When the locking pin 4 is telescopically mounted on the bracket 2 and the table 1 is to be fixed to the bracket 2, first press the locking pin 4 inward toward the bracket 2, and flip the buckle 3 downward so that the buckle 3 is placed vertically. At this time, after releasing the locking pin 4, the locking pin 4 will pass through the locking hole 31 and be pressed against the bottom of the locking hole 31 under the push of the return spring 5.

[0044] Because the end of the locking pin 4 protrudes from the locking hole 31 and is pressed against the bottom of the locking hole 31, the locking pin 4 is difficult to dislodge from the buckle plate 3 when the buckle plate 3 swings slightly, which improves the convenience and stability of the locking structure in fixing the table 1 and the bracket 2.

[0045] More specifically, such as Figure 4As shown, the connector 22, locking post 4, and fixing tube 6 are arranged in a cylindrical shape. The outer diameter of the inner end of the locking post 4 and the fixing tube 6 is larger than the outer diameter of the outer end. The outer diameter of the inner end of the fixing tube 6 is adapted to the inner diameter of the horizontal tube 21. The outer diameter of the return spring 5 is smaller than the inner diameter of the fixing tube 6 and the outer diameter of the inner end of the locking post 4. The outer diameter of the outer end of the connector 22 is larger than the outer diameter of the inner end and is adapted to the outer diameter of the horizontal tube 21. Multiple anti-detachment protrusions 61 are formed on the outer surface of the inner end of the fixing tube 6. The anti-detachment protrusions 61 are distributed along the length direction of the fixing tube 6.

[0046] When it is necessary to slide the locking pin 4 on the bracket 2, first place the locking pin 4 in the connector 22 and make the outer end of the locking pin 4 pass through the through hole at the outer end of the connector 22. Then place one end of the return spring 5 in the fixing tube 6, insert the outer end of the fixing tube 6 into the connector 22 and clamp it. Finally, insert the inner end of the connector 22 into the horizontal tube 21 and clamp it. At this time, the locking pin 4 can be slidably installed on the bracket 2.

[0047] The two ends of the return spring 5 abut against the inner wall of the inner end of the fixing tube 6 and the outer end of the locking pin 4, respectively, so that the outer end of the locking pin 4 remains protruding from the connector 22 in the natural state. The insertion and cooperation between the anti-detachment protrusion 61 and the anti-detachment groove 221 can further improve the stability of fixing the fixing tube 6 and the connector 22, prevent the fixing tube 6 from loosening during use, and further enable the return spring 5 to effectively push the outer end of the locking pin 4 out of the connector 22.

[0048] In this embodiment, the fixing tube 6 and the connector 22 are threadedly connected to the anti-detachment groove 221 via the anti-detachment protrusion 61. In addition, the fixing tube 6 and the connector 22 can also be engaged by the snap-fit ​​block or the snap-fit ​​groove, or fixed by screws.

[0049] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
