Description

Technical Field

[0001] The utility model relates to the technical field of furniture products, in particular to a folding leg stand that can be quickly increased in height, and also to a folding table with the folding leg stand. Background Art

[0002] Tables are one of the indispensable furniture in people's daily lives. With the rapid development of my country's national economy, people's living standards have been greatly improved. More and more people are traveling and camping outdoors, which reflects people's diversified pursuit of modern life. In the past, when people were traveling and camping, they mostly spread a piece of plastic sheet on the ground and placed their food on the plastic sheet. This dining method is neither hygienic nor in line with my country's traditional dining habits. The folding table of the prior art can fold the table legs toward the table top. After folding, the volume of the folding table is greatly reduced, making it very suitable for carrying and using when traveling and camping.

[0003] Among them, the folding table used outdoors often has different requirements for the height of the table due to the need to change the usage occasion at any time, which requires the height of the table to be adjusted. The existing method of adjusting the height of the outdoor folding table top is mostly to set the four legs used to support the table top as telescopic tubes to achieve the height adjustment of the table top.

[0004] For example, the "Box-Type Folding Table" disclosed in the Chinese utility model patent with application number ZL201020119845.X (authorization announcement number CN201657967U) includes a right desktop panel, a left desktop panel, a right table frame, a left table frame, a hinged component, a table frame connector, a right upper support tube, a left upper support tube, a right lower support tube, a left lower support tube, a right leg tube, a right telescopic tube, a left telescopic tube, a right transverse tube, a left transverse tube, a right connecting tube, a left connecting tube, an adapter, a locking component, and a positioning sleeve. The locking component is used to control the movement state of two groups of triangular support mechanisms consisting of the left leg tube, the left upper support tube and the left lower support tube and the right leg tube, the right upper support tube and the right lower support tube to achieve the purpose of folding and unfolding the desktop. Here, the relative height of the desktop and the ground is adjusted by means of the telescopic tube, and it is also easy to fold the desktop for easy carrying outside.

[0005] However, this type of folding table also has drawbacks: when the height of the tabletop needs to be adjusted, it is necessary to press and hold the buttons on both legs on the same side simultaneously to perform auxiliary adjustment, making it impossible to achieve quick adjustment. In addition, due to the structure of the telescopic rod itself, the telescopic rod for height adjustment extends into the leg tube and needs to move up and down relative to the leg tube. Therefore, there is a gap between the telescopic rod and the leg tube, which inevitably causes shaking. At the same time, the telescopic rod cannot be provided with a support rod for auxiliary support. Outdoor tables are often loaded, and the resulting shaking will inevitably affect the stability of the tabletop, thereby affecting the user experience. Therefore, further improvement is needed.

[0006] Therefore, how to provide a folding table that can quickly adjust the height of the table top and also improve the stability of the table top is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

The second adjustment rod 4 is provided at the bottom end of the second table leg 2 and can be flipped up and down relative to the second table leg 2 to achieve height adjustment. The first end of the first support rod 5 is hinged to the first adjustment rod 3, the first end of the second support rod 6 is hinged to the second adjustment rod 4, and the second end of the first adjustment rod 3 and the second end of the second adjustment rod 4 are hinged to each other and can rotate relative to each other. When the first adjustment rod 3 and the second adjustment rod 4 are both flipped downward to a vertical position to raise the folding tripod, the first support rod 5 and the second support rod 6 can rotate relative to each other to form a straight line and are jointly supported between the first adjustment rod 3 and the second adjustment rod 4 to form a stable structure. A locking mechanism 7 is also provided between the first support rod 5 and the second support rod 6 to ensure that the first support rod 5 and the second support rod 6 always remain in a straight line.

[0039] Among them, in order to make the first adjustment rod 3 and the second adjustment rod 4 better hinged at the bottom of the first table leg 1 and the second table leg 2, and also to make the first adjustment rod 3 and the second adjustment rod 4 both be limited in time after being rotated to the vertical state, reference Figure 4 and Figure 5 As shown, in this embodiment, a first mounting groove 1a for hinged placement of the first adjusting rod 3 is intentionally formed at the bottom end of the first table leg 1, and a first side wall 1b is formed on the outer side of the first mounting groove 1a, which can limit the first adjusting rod 3 from continuing to rotate outward after flipping to a vertical state. The first table leg 1 also has a first hinge hole 1c that passes through the first mounting groove 1a transversely for hinged placement of the first adjusting rod 3; a second mounting groove 2a for hinged placement of the second adjusting rod 4 is also formed at the bottom end of the second table leg 2, and a second side wall 2b is formed on the outer side of the second mounting groove 2a, which can limit the second adjusting rod 4 from continuing to rotate outward after flipping to a vertical state. The second table leg 2 also has a second hinge hole 2c that passes through the second mounting groove 2a transversely for hinged placement of the second adjusting rod 4.

[0040] Secondly, in order to ensure that the first adjusting rod 3 and the second adjusting rod 4 can be timely limited after being rotated to the horizontal state, refer to Figure 4 and Figure 5 As shown, in this embodiment, a first limiting portion 1d is formed on the inner side of the first mounting groove 1a to limit the first adjusting rod 3 from continuing to rotate inward after flipping to a horizontal state, and a second limiting portion 2d is formed on the inner side of the second mounting groove 2a to limit the second adjusting rod 4 from continuing to rotate inward after flipping to a horizontal state.

[0041] In addition, in order to prevent the first adjustment rod 3 or the second adjustment rod 4 from rubbing against the first table leg 1 and the second table leg 2 during the subsequent adjustment process and damaging the surface, the first installation groove 1a and the second installation groove 2a can be expanded outward to leave space, and a protective sleeve 1e can be embedded in the inner wall of the first installation groove 1a and the second installation groove 2a for protection. For details, please refer to Figure 7 shown.

[0042] In addition, in order to better articulate the first support rod 5 and the second support rod 6, and to limit each other after relatively rotating to the set position, refer to Figure 5 and Figure 6 As shown, in this embodiment, the second end of the first support rod 5 is formed with a third mounting groove 5a for hinged placement of the second end of the second support rod 6, and the bottom of the third mounting groove 5a is formed with a bottom wall 5b that can limit the second support rod 6 from rotating to a horizontal state and then continuing to rotate. The first support rod 5 is also provided with a third hinge hole 5c that passes through the third mounting groove 5a horizontally for hinged connection of the second support rod 6, and the second support rod 6 is also provided with a fourth hinge hole 6a that can adapt to the third hinge hole 5c. By arranging a pin shaft 6b that passes through the third hinge hole 5c and the fourth hinge hole 6a, the first support rod 5 and the second support rod 6 can be rotatably hinged together.

[0043] In addition, in order to optimize the overall structure of the locking mechanism 7 so that it can better lock the first support rod 5 and the second support rod 6 into a straight state, refer to Figure 6 As shown, the locking mechanism 7 here includes a limit groove 7a provided on the second end face of the first support rod 5, a limit pin 7b movably provided on the second support rod 6 and capable of being embedded in the limit groove 7a, and a reset member 7c for driving the limit pin 7b to always move toward the limit groove 7a. When the first adjusting rod 3 and the second adjusting rod 4 are both flipped to a vertical state, the limit pin 7b can be embedded and positioned in the limit groove 7a so that the first support rod 5 and the second support rod 6 always remain in a straight line.

[0044] At the same time, in order to make the limiting pin 7b slide back and forth along the second support rod 6 better, refer to Figure 6 As shown, the second support rod 6 in this embodiment is also provided with a waist hole 7d along the horizontal direction for the limit pin 7b to pass through and move back and forth. The reset member 7c is a tension spring, and the two ends of the tension spring are respectively connected to the limit pin 7b and the pin shaft 6b.

[0045] In this embodiment, in order to better fix the first table leg 1 and the second table leg 2 together, Figure 1 As shown, a cross bar 8 is connected between the first table leg 1 and the second table leg 2 to fix the first table leg 1 and the second table leg 2 together.

[0046] In addition, this embodiment also provides a folding table, please refer to Figures 8 to 14 shown.

[0047] The folding table here includes a table top 9 and a folding leg. The table top 9 can be a conventional double-jointed panel or a single integral table top. The folding leg can be flipped and arranged at the bottom of the table top 9 and can form a vertical support state and a horizontal folding state between the table top 9. Figure 8 The figure shows the structure of the folding table with the table top in the raised state. Figure 9 Shown is a schematic diagram of the structure of a folding table with the tabletop in a lowered state.

[0048] In this embodiment, in order to allow the table top 9 to be quickly folded for easy carrying, Figure 10 and Figure 11 As shown, the table top 9 includes a first table top 91 and a second table top 92 that can rotate relative to each other to form an expanded state or a folded state. The bottom of the first table top 91 and the second table top 92 are both provided with folding legs. A support mechanism 9a is provided between the folding legs and the bottoms of the first table top 91 and the second table top 92 to support the folding legs and maintain them in a vertical state. A locking device 9b is also provided between the first table top 91 and the second table top 92 to maintain the first table top 91 and the second table top 92 in an expanded state. The support mechanism 9a can adopt a conventional double-link mechanism, for specific reference Figure 9 As shown, a limiting mechanism 9a1 is specifically provided between the double links to ensure that the support mechanism 9a always maintains a supporting state. The limiting mechanism includes a slot 9a2 and a buckle 9a3, respectively provided on the double links. The slot 9a2 and the buckle 9a3 engage with each other to lock the double links in a linear state, thereby preventing the double links from folding. The locking device 9b includes a reversible lock 9b1 with a buckle slot 9b2. By flipping the lock 9b1, the buckle slot 9b2 is buckled onto the pin used to hinge the first table board 91 and the second table board 92, thereby achieving mutual locking of the first table board 91 and the second table board 92. By reversing the lock 9b1, the first table board 91 and the second table board 92 can be quickly released.

[0049] In this embodiment, in order to make the folding table have good strength and stability while reducing the cost, the first table top 91 and the second table top 92 can be made of injection molded plates or blow molded plates. Figure 10 The shown is an injection molded plate. Figure 12 and Figure 13 The figure shows a blow-molded board, and the bottom of the first table board 91 and the second table board 92 are both provided with a frame 9c, where the frame 9c is embedded in the edge of the outer frame of the first table board 91 and the second table board 92. The frame 9c is mainly made of high-strength materials such as metal, so as to enhance the overall strength of the first table board 91 and the second table board 92, wherein the support for the first table leg 1 and the second table leg 2 can be flipped and arranged on the frame 9c, and the support mechanism 9a is supported between the frame 9c and the folding leg.

[0050] In this embodiment, in order to make the entire folding table easier to carry out after folding, Figures 12 to 14 As shown, a handle 10 for easy grasping is specially provided on the side of the table top 9. The handle 10 here can be made of a cloth belt or a cloth strip.

[0051] It is necessary to explain additionally here that in this embodiment, a first adjusting rod 3 is provided at the bottom end of the first table leg 1, which can be flipped up and down relative to the first table leg 1 to achieve height adjustment, and a second adjusting rod 4 is provided at the bottom end of the second table leg 2, which can be flipped up and down relative to the second table leg 2 to achieve height adjustment, and a first supporting rod 5 whose first end is hinged on the first adjusting rod 3 and a second supporting rod 6 whose first end is hinged on the second adjusting rod 4 are provided, and the second ends of the first adjusting rod 3 and the second ends of the second adjusting rod 4 are hinged to each other and can rotate relative to each other, when it is necessary to increase the height of the foldable tripod, the first adjusting rod 3 and the second adjusting rod 4 can be flipped outward synchronously to a vertical state to achieve rapid increase of the foldable tripod. The first support rod 5 and the second support rod 6 here can also be rotated synchronously to a straight state after the first adjustment rod 3 and the second adjustment rod 4 are rotated to a vertical state, so that they can jointly support between the first adjustment rod 3 and the second adjustment rod 4 so that the first adjustment rod 3 and the second adjustment rod 4 can form a stable support structure. By providing a locking mechanism 7 between the first support rod 5 and the second support rod 6, which can always keep the first support rod 5 and the second support rod 6 in a straight state, the stability of the first adjustment rod 3 and the second adjustment rod 4 when in a load-bearing state is further improved, so that the folding tripod can be quickly increased in height while also having good stability of the folding legs and reducing the shaking of the table when in use. Another point: in order to better adapt to each other and facilitate their respective shaping, the first table leg 1, the second table leg 2, the first adjustment rod 3, the second adjustment rod 4, the first support rod 5 and the second support rod 6 are all made of square tubes.
