A folding table fixing structure

Abstract

This utility model discloses a fixing structure for a folding table, including multiple tabletops arranged in sequence, a hinge body, a fixing shaft, and connecting pipes disposed on the sides of the tabletops. Limiting notches are passed through the outer sides of the connecting pipes away from both ends. The limiting notches on adjacent connecting pipes enclose and form limiting grooves. The hinge body is inserted into the limiting groove and abuts against the inner wall of the limiting groove. Both ends of the fixing shaft pass through the hinge body and are engaged within the connecting pipes. The limiting grooves limit the horizontal movement of the hinge body, while the fixing shafts secure the hinge body to the connecting pipes, limiting its height. Furthermore, the hinge body and fixing shafts allow for the rotatable connection of adjacent tabletops. This design offers advantages such as simple structure and ease of assembly and disassembly. Because the hinge body is located in the inner section of the tabletop, it provides stable support, improving the stability of the tabletop.

Description

Technical Field

[0001] This utility model relates to the technical field of folding tables, and more particularly to a fixing structure for folding tables. Background Technology

[0002] Egg roll tables and folding tables are a type of table that is easy to carry outdoors and can be folded and stored. The tabletops of existing egg roll tables and folding tables include multiple table panels and hinges that connect and fix adjacent table panels. However, the hinges are mostly installed at both ends of the table panels, which results in a lack of fixed structure in the inner section of the table panels, affecting the stability of the tabletop. This needs to be improved. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies, such as the lack of support and fixing structure in the inner section of the tabletop due to the hinge being located at the outer end of the tabletop, which affects the stability of the tabletop. It provides a new fixing structure for folding tables.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] A folding table fixing structure includes multiple table panels arranged in sequence, a hinge body, a fixing shaft, and a connecting tube disposed on the side of the table panel. The connecting tube has a limiting notch extending through its outer side away from both ends. The limiting notches on adjacent connecting tubes enclose a limiting groove. The hinge body is inserted into the limiting groove and abuts against the inner wall of the limiting groove. Both ends of the fixing shaft extend out from the hinge body and are engaged in the connecting tube.

[0006] The hinge body can be limited horizontally by the limiting groove, and the hinge body can be clamped onto the connecting tube by the fixed shaft to limit the height of the hinge body. Then, the adjacent tabletops can be rotated and connected by the hinge body and the fixed shaft. It has the advantages of simple structure and easy disassembly and assembly. Since the hinge body is located in the inner section of the tabletop, it can provide stable support for the tabletop and improve the stability of the tabletop.

[0007] Preferably, in the folding table fixing structure described above, the connecting tube is provided with a plurality of limiting notches distributed along the length direction of the connecting tube, and the number of the fixing shafts corresponds one-to-one with the number of limiting notches.

[0008] Each connecting tube has multiple limiting notches distributed along the inner section of the tabletop, which, together with the corresponding number of hinge bodies and fixed shafts, can provide multi-point fixation and support for the inner section of the tabletop, further improving the stability of the tabletop.

[0009] Preferably, in the above-described folding table fixing structure, the connecting tube has a side opening area facing the inside of the tabletop, and the side opening area is distributed on the side wall of the connecting tube on the tabletop where they face each other.

[0010] The side opening area allows users to easily observe the position of the fixed shaft, enabling them to clamp the fixed shaft in the appropriate position on the connecting tube. The side opening area is close to the tabletop, resulting in a smaller opening in the connecting tube and improving the stability of the fixed shaft clamping inside the connecting tube.

[0011] Preferably, in the above-described folding table fixing structure, the hinge body has a through hole for the fixing shaft to pass through, the inner diameter of the through hole is adapted to the inner diameter of the connecting pipe, the through hole is close to the side end of the hinge body, and the side end of the hinge body is arc-shaped.

[0012] The side of the hinge body is arc-shaped, which improves the smoothness of the hinge body being inserted into the limiting groove.

[0013] Preferably, in the folding table fixing structure described above, the inner surface of the hinge body is recessed inward to form a finger-placement area.

[0014] The finger rest area makes it easy for users to pick up and move the hinge body.

[0015] Preferably, in the folding table fixing structure described above, the outer surface of the tabletop has a clearance groove that communicates with the limiting notch, and the number of clearance grooves corresponds one-to-one with the number of limiting notches.

[0016] The clearance groove allows for clearance when the hinge body is inserted into the limiting groove, further improving the smoothness of the hinge body insertion into the limiting groove.

[0017] Preferably, in the above-described folding table fixing structure, the end of the table board is covered with a plug, the upper surface of the plug is provided with an inwardly recessed positioning groove, and the lower surface of the table board is provided with a reinforcing rib extending along the length of the table board, the end of the reinforcing rib being inserted into the positioning groove for a plug-in fit.

[0018] The end caps can cover and protect the ends of the tabletop, improving the smoothness of the tabletop edges. The reinforcing ribs improve the structural strength of the tabletop, and the positioning grooves and the interlocking of the reinforcing ribs enhance the stability of the end caps covering the tabletop.

[0019] Preferably, in the above-described folding table fixing structure, a reinforcing plate is provided in the middle of the end cap, and locking posts are provided on both sides of the reinforcing plate on the end cap. An abutting slope is provided on the outer surface of the reinforcing plate near the locking posts. The lower end of the abutting slope is connected to the locking posts, and the upper end of the abutting slope gradually slopes upward away from the locking posts. The locking posts are inserted into the connecting pipe and engaged. The abutting slope abuts against the inner wall of the side opening area.

[0020] The reinforcement plate improves the structural strength of the plug itself. The plug and the table are connected and fixed by the locking post and the connecting pipe. It has the advantages of simple structure and easy assembly. The abutment slope improves the tightness of the connection between the connecting pipe and the plug and improves the stability of the plug installed at the end of the table.

Detailed Implementation

[0026] 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

[0027] like Figures 1-4 As shown, a folding table fixing structure includes multiple tabletops 1 arranged in sequence, a hinge body 2, a fixing shaft 3, and a connecting pipe 4 disposed on the side of the tabletop 1. The outer side of the connecting pipe 4 away from both ends has a limiting notch 41. The limiting notches 41 on adjacent connecting pipes 4 surround to form a limiting groove 5. The hinge body 2 is inserted into the limiting groove 5 and is in contact with the inner wall of the limiting groove 5. The two ends of the fixing shaft 3 pass through the hinge body 2 and are engaged in the connecting pipe 4.

[0028] Preferably, the connecting pipe 4 is provided with a plurality of limiting notches 41 distributed along the length direction of the connecting pipe 4, and the number of the fixed shaft 3 corresponds one-to-one with the number of limiting notches 41.

[0029] Preferably, the connecting pipe 4 has a side opening area 42 in the direction of the inside of the tabletop 1, and the side opening area 42 is distributed on the side wall of the connecting pipe 4 on the tabletop 1 that is directly opposite each other.

[0030] Preferably, the hinge body 2 has a through hole 21 for the fixed shaft 3 to pass through. The inner diameter of the through hole 21 is adapted to the inner diameter of the connecting pipe 4. The through hole 21 is close to the side end of the hinge body 2, and the side end of the hinge body 2 is arc-shaped.

[0031] Preferably, the inner surface of the hinge body 2 is recessed inward to form a finger-releasing area 22.

[0032] Preferably, the outer surface of the tabletop 1 has a clearance groove 11 that communicates with the limiting notch 41, and the number of clearance grooves 11 corresponds one-to-one with the number of limiting notches 41.

[0033] Preferably, the end of the tabletop 1 is covered with a plug 6, the upper surface of the plug 6 is provided with an inwardly recessed positioning groove 61, and the lower surface of the tabletop 1 is provided with a reinforcing rib 12 extending along the length of the tabletop 1, the end of the reinforcing rib 12 is inserted into the positioning groove 61 and engaged.

[0034] Preferably, a reinforcing plate 62 is provided in the middle of the plug 6, and locking posts 63 are provided on both sides of the reinforcing plate 62 on the plug 6. An abutting slope 621 is provided on the outer surface of the reinforcing plate 62 near the locking post 63. The lower end of the abutting slope 621 is connected to the locking post 63, and the upper end of the abutting slope 621 gradually slopes upward away from the locking post 63. The locking post 63 is inserted into the connecting pipe 4 and engaged. The abutting slope 621 abuts against the inner wall of the side opening area 42.

[0035] Specifically, such as Figure 1 , Figure 2 As shown, the front of the hinge body 2 is planar, the finger placement area 22 is distributed in the middle of the back of the hinge body 2, and the through hole 21 is located on the left and right sides of the finger placement area 22. The through hole 21 and the finger placement area 22 extend along the height direction of the hinge body 2. In this embodiment, adjacent tabletops 1 are connected and fixed by two hinge bodies 2. The number of hinge bodies 2 and limiting grooves 5 can be increased or decreased according to the length of the tabletop 1 and the installation requirements.

[0036] When multiple tabletops 1 need to be connected and fixed side by side, first insert both sides of the hinge body 2 into the corresponding limiting notches 41 on the adjacent tabletops 1. Then, insert the fixing shaft 3 into the connecting tube 4 and move the fixing shaft 3 through the side opening area 42 until the end of the fixing shaft 3 passes through the through hole 21. At this time, the hinge body 2 can be limited in height by the insertion and cooperation of the fixing shaft 3 and the connecting tube 4. Since the through hole 21 is directly opposite to the inner cavity of the connecting tube 4 and the front and rear ends of the hinge body 2 are in contact with the inner wall of the end of the limiting notch 41, the hinge body 2 can be limited in the horizontal direction by the limiting groove 5. The hinge body 2 realizes the rotational connection between adjacent tabletops 1 and can also fix and support the inner section of the tabletop 1, improving the stability and simplicity of the tabletop.

[0037] like Figure 1 , Figure 4 As shown, the plug 6 includes a vertical plate, a reinforcing plate 62 located at the inner end of the vertical plate, and a locking post 63 for cooperating with the connecting pipe 4. The reinforcing plate 62 has a double-layer hollow structure. There are two locking posts 63 distributed on the left and right sides of the reinforcing plate 62. There are two positioning grooves 61 distributed on the upper surface of the reinforcing plate 62. The lower surface of the table board 1 has two reinforcing ribs 12 integrally formed. The reinforcing ribs 12 arch away from the table board 1, and the arching arc of the reinforcing ribs 12 matches the concave arc of the positioning grooves 61.

[0038] When the plug 6 is fastened to the end of the tabletop 1, first align the locking pin 63 with the inner cavity of the connecting pipe 4, then move the plug 6 towards the tabletop 1 until the locking pin 63 is fully inserted into the connecting pipe 4, and insert the end of the reinforcing rib 12 into the corresponding positioning groove 61 for mating. The inner end of the vertical plate abuts against the ends of the connecting pipe 4 and the tabletop 1. At this time, the plug 6 can be fastened to the end of the tabletop 1. In this embodiment, the edge of the vertical plate is flush with the edge of the connecting pipe 4 and the tabletop 1, and the outer end of the vertical plate is arc-shaped, which can improve the smoothness of the end of the tabletop 1 and facilitate user use.

[0039] 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.
