背景技术Background technique

折叠桌是可具有折叠功能的桌子，因方便折叠，便于运输这个特点，在宴会、会议、展会等临时招待性场所经常看到他的身影，已成为酒店、展会等场所不可缺少的家具。The folding table is a table that can be folded. It is easy to fold and easy to transport. It is often seen in temporary reception places such as banquets, conferences, exhibitions, etc. It has become an indispensable piece of furniture for hotels, exhibitions and other places.

考虑对实际使用大小的需求以及占地空间的限制，现有的技术中，出现了一些可以实现桌板面积可调的折叠桌。Considering the need for actual use size and the limitation of floor space, in the prior art, there are some folding tables that can realize adjustable table area.

申请号为：201020641624.9专利名称为：伸缩折叠桌的中国专利公开了一种可以伸长使用的伸缩折叠桌。解决了现有技术中的折叠桌不能伸缩，长度固定不能延伸的缺点，包括支撑架和连接支撑架上方的桌板，支撑架包括两对称平行设置的支撑脚和铰接在支撑脚上端的支撑杆，支撑杆包括固定支撑杆及伸缩支撑杆，桌板包括常用桌板及脱卸桌板，常用桌板连接在固定支撑杆上，脱卸桌板与伸缩支撑杆相连。支撑杆采用固定支撑杆和伸缩支撑杆的组合方式，可以将支撑杆延长，延长部分与脱卸桌板相配合，这样延长部分被脱卸桌板覆盖，桌面得到扩展。采用该结构的的伸缩折叠桌存在的缺陷是，通过常用桌板及脱卸桌板两个部分组合，或者单独使用常用桌板，来实现桌板面积的调整，因此其伸缩折叠桌的桌面面积可调范围小，无法更加精确地根据需求调整桌面的面积，而且常用桌板及脱卸桌板为相互独立的两个组件，使得伸缩折叠桌的组件较多，整体性不强。The application number is: 201020641624.9 Patent entitled: The Chinese patent of the telescopic folding table discloses a telescopic folding table that can be used for elongation. The utility model solves the defects that the folding table in the prior art can not be stretched and can not be extended in length, and comprises a support frame and a table plate connected above the support frame. The support frame comprises two symmetrically arranged support legs and a support rod hinged on the upper end of the support foot. The support rod comprises a fixed support rod and a telescopic support rod. The table board comprises a common table board and a detachable table board. The common table board is connected to the fixed support rod, and the detachment table board is connected with the telescopic support rod. The support rod adopts a combination of a fixed support rod and a telescopic support rod, and the support rod can be extended, and the extension portion is matched with the detachment table board, so that the extension portion is covered by the detachable table board, and the table top is expanded. The telescopic folding table adopting the structure has the disadvantage that the table area is adjusted by the combination of the two parts of the common table and the detachable table board, or the common table board is used alone, so the table top area of the telescopic folding table can be The adjustment range is small, and the area of the table top cannot be adjusted more accurately according to the requirements. Moreover, the common table board and the detachment table board are two independent components, so that the components of the telescopic folding table are more and the overallity is not strong.

另外，桌子是日常生活工作中必不可少的用品，在户外活动时可折叠的桌椅能够大大方便搬运的过程，但是常规的户外折叠桌仅能够将桌脚部分收缩打开，或者直接将桌面对折。桌面部分的长度是无法自由调节的，或者仅供2个人使用，或者仅供4个人使用，更大的可供多人使用。如果人少而桌子过大，携带时会非常不便，如果人多带了小桌子就不够用，因此普通的折叠桌难以满足对桌面长度不同的需求。In addition, the table is an indispensable item in daily life work. The folding table and chairs can greatly facilitate the handling process during outdoor activities, but the conventional outdoor folding table can only be used for the table legs. Divide open, or fold the desktop directly. The length of the desktop section is not freely adjustable, or for 2 people only, or for 4 people only, and larger for multiple people. If the number of people is too small and the table is too large, it will be very inconvenient to carry. If a person has a small table, it is not enough. Therefore, the ordinary folding table is difficult to meet the needs of different desktop lengths.

对于本领域的技术人员来说，如何设计一种可伸缩桌面的折叠桌，满足户外不同的使用需求，是目前需要解决的技术问题。For those skilled in the art, how to design a folding table of a retractable tabletop to meet different outdoor use requirements is a technical problem that needs to be solved at present.

The folding table is mainly composed of a table frame 01, a table top 02 and a table leg 03. The table frame 01 is formed by at least two table tube sets. The figure of the utility model shows two ways of the table tube set, two table tubes They are all hollow structures with different sizes. The outer wall of one of them is in contact with the inner wall of the other, and the two can form a sliding. In order to ensure that the two table tubes are separated without exceeding the limit when sliding, at the end of the larger table tube The part is provided with a stop bolt, which can be locked with the smaller-sized table tube when it is at the designated position. In this embodiment, the entire table frame 01 is a rectangular box, which is composed of two table tubes, each of which is U-shaped, and the size of the two end portions of one of the U-shaped table tubes is relatively small. It is placed in another U-shaped table tube, rather than the cross-sectional size of the entire table tube is very small. The smaller U-shaped table tube forms a step for abutting against the end of the other table tube, and when the abutment is the smallest state of the entire folding table table 02. 12 is a partial enlarged view of the table frame 01 in cooperation with each other, and FIG. 13 is a schematic cross-sectional view of the table frame 01 being fitted to each other. A groove is formed in the cross section of the table frame 01, and is opened in the horizontal direction. The table frame 01 on both sides is provided with a groove and the opening direction is opposite. The two ends of the panel 02 in the table top 02 can be inserted into the groove. It can limit the movement of the panel 021 in the vertical direction, and the bottom of the table 02 can provide a good supporting effect. The structural advantage is that the panel 021 can be prevented from sliding out of the table frame 01 during use, allowing only movement in the horizontal direction. Of course, the structure of the cross section of the table frame 01 can be correspondingly improved according to the specific use requirements, and is not limited herein.

桌面02是由多块形状和构造相同的面板021组成的平板，各个面板021的横截面形状相同，相邻的两块面板021之间能够相互滑动连接，能够在一定的范围内实现相互滑动，改变两块面板021之间的距离，能够面板021间距的改变，调整了桌面02的长度，从而改变整个桌面02的可用面积。在桌架01上设置了相应的滑槽，各块面板021能够在桌架01的顶部滑动。The table top 02 is a flat plate composed of a plurality of panels 021 having the same shape and structure. The cross-sectional shape of each panel 021 is the same, and the adjacent two panels 021 can be slidably connected to each other, and can slide to each other within a certain range. Change the distance between the two panels 021, can face The change in the pitch of the board 021 adjusts the length of the table 02, thereby changing the available area of the entire table 02. Corresponding chutes are provided on the table frame 01, and each of the panels 021 is slidable on the top of the table frame 01.

桌脚03设置在桌架01的底部侧面，分别位于桌架01的两端，桌脚03与桌架01为转动连接，在使用时桌脚03与桌架01为垂直位置关系，在折叠使用时桌脚03能够转动90度与桌架01平行放置，尽可能占用较小的空间。另外，为了保证桌脚03支撑的稳定性，桌架01与桌脚03之间设置桌脚支撑条031，桌脚支撑条031转动设置，设置为两段，桌脚支撑条031与桌架01和桌脚03连接处均为转动连接，两段之间也为转动设置，便于折叠。在两段桌脚支撑条031之间还设置相应的卡紧件，在正常使用时卡紧件将桌脚支撑条031保持平直，确保稳定。The table legs 03 are disposed on the bottom side of the table frame 01, respectively located at the two ends of the table frame 01, and the table legs 03 and the table frame 01 are connected in a rotating manner. When in use, the table legs 03 and the table frame 01 are in a vertical positional relationship, and are used in folding. When the table foot 03 can be rotated 90 degrees and placed parallel to the table frame 01, it takes up as much space as possible. In addition, in order to ensure the stability of the support of the table leg 03, a table leg support bar 031 is arranged between the table frame 01 and the table leg 03, and the table leg support bar 031 is rotated and set to two segments, the table leg support bar 031 and the table frame 01 The connection between the table and the foot 03 is a rotary connection, and the two sections are also rotated to facilitate folding. A corresponding clamping member is also disposed between the two legs supporting the strip 031. The clamping member keeps the table supporting bar 031 straight during normal use to ensure stability.

具体地，如图14所示，为桌面02的装配图，所示为本实用新型中所提供的一种具体的设置结构。面板021为具有一定厚度的平板，在面板021的两侧分别开设扁长状的腰孔0211，相邻的两块面板021之间通过铰链022实现滑动连接。铰链022为扁长的块状结构，一端开设螺栓孔，能够通过螺栓固定在一个面板021的边缘。铰链022的其余部分伸出，在伸出一端的端部设置向面板021本体凸出的滑块，滑块能够***另一块面板021的腰孔0211中实现滑动，腰孔0211与螺栓孔分别位于面板021的两侧，滑块211的末端尺寸较大，形成阶梯，在滑块***腰孔0211后防止滑出。上述结构也仅作为一种具体设置形式，还可直接将相互配合滑动的部件直接设置在面板021上，通过钩挂等方式实现滑动连接。Specifically, as shown in FIG. 14, which is an assembly diagram of the table top 02, a specific arrangement structure provided in the present invention is shown. The panel 021 is a flat plate having a certain thickness, and a flat elongated waist hole 0211 is respectively formed on both sides of the panel 021, and the adjacent two panels 021 are slidably connected by a hinge 022. The hinge 022 is a flat and long block structure with a bolt hole at one end and can be fixed to the edge of a panel 021 by bolts. The remaining portion of the hinge 022 is extended, and a slider protruding toward the body of the panel 021 is disposed at an end portion of the protruding end. The slider can be inserted into the waist hole 0211 of the other panel 021 to realize sliding, and the waist hole 0211 and the bolt hole are respectively located. On both sides of the panel 021, the end of the slider 211 is large in size, forming a step, and is prevented from slipping out after the slider is inserted into the waist hole 0211. The above structure is also only used as a specific arrangement form, and the components that slide together with each other can be directly disposed on the panel 021, and the sliding connection can be realized by hooking or the like.

进一步，为了确保在任何打开尺寸时桌面02均没有缝隙，不会使细小的东西从两块面板021之间掉下，对面板021的形状还可进行进一步扩展，面板021的顶部与另一面板021相接的一侧向下凹陷，凹陷是指竖直方向的尺寸改变；相对的另一侧向外侧凸起，形成薄板，这里所说的凸起是指水平方向上尺寸的延长，也就是说一块面板021上的凸起能够搭接在相邻的一个面板021的凹陷处，在水平方向上凹陷的长度与向外侧凸起的长度相同，目的是在桌面02最小状态时整个桌面02的上表面平整。在将桌面02拉开时由于有凹陷有存在会形成交替的台阶，以此确保在最大状态下桌面02的完整性。Further, in order to ensure that the table 02 has no gap at any opening size, and does not cause small things to fall from between the two panels 021, the shape of the panel 021 can be further expanded, the top of the panel 021 and the other panel The one side of the 021 is recessed downward, the recess means a change in the dimension in the vertical direction; the other side of the opposite side is convex outward to form a thin plate, and the protrusion here refers to the extension of the dimension in the horizontal direction, that is, It is said that the protrusion on a panel 021 can be overlapped in the recess of the adjacent one of the panels 021, and the length of the recess in the horizontal direction is the same as the length of the protrusion to the outside, in order to minimize the state of the desktop 02 when the desktop 02 is in the minimum state. The upper surface is flat. When the table 02 is pulled apart, an alternating step is formed due to the presence of a depression, thereby ensuring the table at the maximum state.
