Description

Technical Field

[0002] A folding table is a table with a folding function, which is usually made of steel and wood. Folding tables are very common living equipment in daily life and are widely used in scenes such as home, office or outdoor activities. Folding tables are mostly folded by folding and contracting the support frame, thereby reducing the space required for transportation and storage of the folding table.

[0003] There are many types of folding tables available, the most common ones are as follows:

[0004] 1. CN203194922U discloses a novel foldable table, the legs of which can be folded into grooves at the bottom of the tabletop when not in use, thereby achieving folding. However, the desktop of this type of folding table is not foldable, and the desktop is a hard board, so the volume is still large after folding, and the portability is poor; 2. CN202874321U discloses a folding table, which is similar to the above-mentioned folding table structure, except that the desktop is set to a foldable structure, so the volume of the folding table after folding is reduced compared with the previous type of folding table, but overall, the volume is still large, which is not conducive to carrying; 3. CN202009808U discloses a portable folding table, the desktop of the folding table is a roller shutter plate structure connected by ropes, and the desktop can be rolled up when not in use. Therefore, this type of folding table can not only fold the legs but also the desktop, and the folded volume is smaller, but the desktop and legs of this type of folding table are folded separately, and the special folding structure of the desktop also requires a support structure of the desktop, and the support structure and the desktop and legs are generally independent structures.

DETAILED DESCRIPTION

[0032] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0036] like Figure 1-13 As shown, the present application provides a folding table bracket, including two table top rods 100 arranged in parallel and at intervals, and both ends of the table top rods 100 are rotatably provided with table legs 200, and the table legs 200 can be rotated outwardly away from the table top rods 100 in a first direction and unfolded to contact with a placement plane to support the table top rods 100, and can also be rotated inwardly in the first direction and folded to fit on one side of the table top rods 100, and two transverse connecting rods 300 are connected between the ends of the same side of the two table top rods 100, one end of the transverse connecting rod 300 is rotatably connected to the table top rod 100 through a first connecting member 400, and the other end of the transverse connecting rod 300 is connected to the table top rod 100 through a second connecting member 400. The connecting member 500 is rotatably connected to another transverse connecting rod 300, and the two transverse connecting rods 300 can be rotated to expand or rotated to fold to drive the two table top rods 100 to move away from or move closer to each other along the second direction. An upper support rod 600 is also connected between the transverse connecting rod 300 and the table leg 200 on the same table top rod 100. One end of the upper support rod 600 is rotatably connected to the table leg 200 through a third connecting member 700, and the other end of the upper support rod 600 is hinged to the middle part of the transverse connecting rod 300. Therefore, the table leg 200 can drive the two table top rods 100 to move closer to or away from each other while rotating, folding or rotating and expanding relative to the table top rod 100.

[0037] It is worth mentioning that Figure 1-2 As shown, the first direction is the length direction of the folding table bracket, and the second direction is the width direction of the folding table bracket. The first direction and the second direction are perpendicular to each other in a horizontal plane.

[0038] Specifically, when the table leg 200 rotates outward from the folded position to the unfolded position along the first direction, the upper support rod 600 rotatably connected between the table leg 200 and the transverse link 300 can push the transverse link 300 under the drive of the table leg 200, and the transverse link 300 rotates from the folded state to the unfolded state and pushes the two table top rods 100, so that the two table top rods 100 move away from each other along the second direction; when the table leg 200 rotates inward from the unfolded position to the folded position along the first direction, the upper support rod 600 rotatably connected between the table leg 200 and the transverse link 300 can pull back the transverse link 300 under the drive of the table leg 200, and the transverse link 300 rotates from the unfolded state to the folded state and pulls back the two table top rods 100, so that the two table top rods 100 move closer to each other along the second direction. Based on the above characteristics, when the folding table stand provided in the present application is in use, it only needs to rotate the table legs 200 to realize the automatic unfolding and automatic folding of the folding table stand. The operation is simple and quick, saving trouble and effort. The folded folding table stand is compact in size, and the transverse connecting rod 300 and the upper support rod 600 are folded between the two table top rods 100. Each table leg 200 is folded and fits against the table top rod 100, which reduces the space required for the folding table stand to be stored and transported, making it easy to carry and store.

[0039] Furthermore, if Figure 3 As shown, first connecting members 400 for connecting with the transverse connecting rod 300 are rotatably arranged on the end surfaces of the two desktop rods 100 on opposite sides. The first connecting member 400 includes a first vertical plate 410 and a first horizontal plate 420 connected by integral molding, and the first vertical plate 410 and the first horizontal plate 420 are arranged perpendicular to each other. The first vertical plate 410 is attached to the end surface of the desktop rod 100 and is hingedly connected to the desktop rod 100, and the first horizontal plate 420 is hingedly connected to one end of the transverse connecting rod 300.

[0040] The ends of the two transverse links 300 on opposite sides are connected by a second connecting member 500, and the second connecting member 500 includes two second hinge seats 510, and the two second hinge seats 510 are respectively fixedly arranged on the ends of the two transverse links 300 on opposite sides. A second hinge 520 and a second abutment 530 are arranged on the end of one side of the second hinge seat 510, and the second hinge 520 is located above the second abutment 530. The two second hinges 520 are hinged to each other, and the two second abutment 530 are suitable for abutting against each other when the two transverse links 300 are rotated to the maximum expansion position to limit the further rotation and expansion of the transverse links 300, and when the two second abutment 530 abut against each other, the angle between the two second hinge seats 510 is 180°, and the two transverse links 300 are spliced ​​end to end and arranged horizontally.

[0041] An upper support rod 600 is connected between the transverse connecting rod 300 and the table leg 200 on the same table top rod 100. One end of the upper support rod 600 is rotatably connected to the table leg 200 through a third connecting member 700. The other end of the upper support rod 600 is hinged to the middle part of the transverse connecting rod 300. The third connecting member 700 includes a third vertical plate 710 and a third horizontal plate 720 that are integrally connected. The third vertical plate 710 is attached to the end surface of the table leg 200 and is hinged to the table leg 200, while the third horizontal plate 720 is hinged to one end of the upper support rod 600.

[0042] In some preferred embodiments, the transverse link 300 is further provided with a cover 310 at the end hinged to the first horizontal plate 420. The cover 310 has an abutment plane. When the transverse link 300 is rotated to the maximum expanded position, the abutment plane of the cover 310 is attached to and abuts against the first vertical plate 410 to limit further rotation of the transverse link 300 and prevent the transverse link 300 from rotating too much.

[0043] Furthermore, the table leg 200 includes a leg tube connector 210 and a leg tube assembly 220, the leg tube connector 210 includes a hinged portion 211 and a fixed connection portion 212, the hinged portion 211 and the fixed connection portion 212 are integrally formed and connected, the hinged portion 211 and the fixed connection portion 212 form an angle, the degree of the angle is between 90° and 140°, preferably, the angle between the hinged portion 211 and the fixed connection portion 212 is 115°, the hinged portion 211 is hingedly connected to the table top rod 100, and the fixed connection portion 212 is fixedly connected to the top of the leg tube assembly 220, so that the leg tube The connecting member 210 and the leg tube assembly 220 can be rotated and folded or rotated and unfolded relative to the table top rod 100 along a first direction. An abutment end cap 230 is also provided at the top end of the leg tube assembly 220. The abutment end cap 230 is suitable for abutting against the bottom end surface of the table top rod 100 when the leg tube assembly 220 is rotated to the maximum unfolded position to limit further rotation of the leg tube assembly 220. The angle between the hinge part 211 and the fixed connection part 212 enables the leg tube assembly 220 to be extended outward when it is rotated to the maximum unfolded position, thereby improving the stability of the leg tube assembly 220 in supporting the table top rod 100.

[0044] like Fig.13 As shown, the distance between the hinge point of the first vertical plate 410 and the table top rod 100 and the hinge point of the hinge part 211 and the table top rod 100 is the first hole distance m, the distance between the hinge point of the hinge part 211 and the table top rod 100 and the hinge point of the third vertical plate 710 and the table leg 200 is the second hole distance n, the distance between the hinge point of the first horizontal plate 420 and the transverse connecting rod 300 and the hinge point of the transverse connecting rod 300 and the upper support rod 600 is the third hole distance a, and the distance between the transverse connecting rod 300 and the upper support rod 600 is the third hole distance a. The distance between the hinge point of the support rod 600 and the hinge point of the upper support rod 600 and the third horizontal plate 720 is the fourth hole distance b, the sum of the third hole distance a and the fourth hole distance b is not greater than the sum of the first hole distance m and the second hole distance n, that is, a+b≤m+n, and the first hole distance m, the second hole distance n, the third hole distance a and the fourth hole distance b are arranged in this way so that when the folding table bracket is fully unfolded, the transverse connecting rod 300, the upper support rod 600 and the table leg 200 form a triangular stabilizing moment, thereby improving the stability of the support. At the same time, the sum of the third hole distance a and the fourth hole distance b is not greater than the sum of the first hole distance m and the second hole distance n, which can prevent the upper support rod 600 from pushing the transverse connecting rod 300 to rotate too far when the folding table bracket is unfolded, resulting in excessive unfolding or excessive folding of the transverse connecting rod 300 and damage.

[0045] Furthermore, if Figure 6-7As shown, the leg tube assembly 220 includes an upper leg tube 221 and a retractable lower leg tube 222 inserted in the upper leg tube 221, and a locking assembly 240 is provided at the connection between the upper leg tube 221 and the lower leg tube 222. The locking assembly 240 is suitable for locking or unlocking the upper leg tube 221 and the lower leg tube 222. A limiting end cover 223 is provided at the top end of the lower leg tube 222, and the limiting end cover 223 is used to interfere with the locking assembly 240 to limit the lower leg tube 222 from telescopically sliding away from the upper leg tube 221. The locking assembly 240 specifically includes a locking seat 241 sleeved on the outer side of the upper leg tube 221 and the lower leg tube 222, a locking button 242 movably provided on the locking seat 241, an elastic member 243 is provided between the locking button 242 and the locking seat 241, and the elastic member 243 can be implemented as a compression spring. The elastic member 243 is suitable for pushing the locking button 242 to reset after the external force acting on the locking button 242 is removed. The end surface of the lower leg tube 222 away from the locking button 242 is provided with a lock A fixed rack 245 and a locking rack 245 are provided with a plurality of tooth grooves 246 arranged along the length direction, and a locking tooth 244 cooperating with the tooth groove 246 is provided on the locking button 242. When the locking button 242 is pressed, the locking tooth 244 disengages from the tooth groove 246 to release the lock on the lower leg tube 222. When the locking button 242 is released, the locking tooth 244 embeds into the tooth groove 246 to lock the sliding of the lower leg tube 222. In other words, the locking button 242 needs to be pressed to telescopically adjust the lower leg tube 222.

[0046] Preferably, the tooth groove 246 includes a locking end face 247 near the bottom end of the lower leg tube 222 and a guide end face 248 near the top end of the lower leg tube 222. The locking end face 247 is arranged perpendicular to the locking rack 245, and the guide end face 248 is arranged obliquely, so that the tooth groove 246 is similar to a V-shaped structure. The locking end face 247 is suitable for abutting against the locking tooth 244 to limit the sliding of the locking tooth 244 relative to the locking rack 245, and the guide end face 248 is suitable for abutting against the locking tooth 244 to limit the sliding of the locking tooth 244 relative to the locking rack 245. The sliding fit of 244 allows the locking tooth 244 to slide along the guide end surface 248. The setting of the locking end surface 247 and the guide end surface 248 allows the locking tooth 244 to only slide unidirectionally along the guide end surface 248 relative to the locking rack 245 toward the top of the lower leg tube 222. That is to say, when the locking button 242 is not pressed, the lower leg tube 222 can be pulled outward to achieve adjustment of different heights, but the lower leg tube 222 cannot be pushed inward and retracted.

[0047] like Figure 9-12As shown, in some preferred embodiments, two lower support rods 800 are further connected between the two table legs 200 on the same side of the two table top rods 100, one end of the lower support rod 800 is hinged on the locking seat 241, and the other end of the lower support rod 800 is rotatably connected to the other lower support rod 800 through a fourth connecting member 900, and the fourth connecting member 900 includes two fourth hinge seats 910, and the two fourth hinge seats 910 are respectively fixedly arranged on the ends of the opposite sides of the two lower support rods 800, and the fourth hinge seats 910 are respectively fixedly arranged on the ends of the opposite sides of the two lower support rods 800, and the fourth hinge seats 910 are respectively fixedly arranged on the ends of the two lower support rods 800. A fourth hinge 920 and a fourth abutment 930 are provided on the end of the side, the fourth hinge 920 is located below the fourth abutment 930, and the two fourth hinges 920 are hingedly connected to each other, so that the two lower support rods 800 can be rotated to a locked state to support and abut the two leg tube assemblies 220, thereby limiting the two leg tube assemblies 220 from approaching each other along the second direction, and the two fourth abutment 930 are suitable for abutting against each other when the two lower support rods 800 are rotated to the locked state to limit the two lower support rods 800 in the locked state.

[0048] Specifically, the two lower support rods 800 in the unlocked state are in a V-shaped structure with the opening downward, and the two lower support rods 800 can rotate between a folded position and an unfolded position as the leg tube assembly 220 is folded and opened. The two lower support rods 800 in the unfolded position can be further rotated downward to a locked state. The two lower support rods 800 in the locked state are in a V-shaped structure with the opening upward. At this time, if the two leg tube assemblies 220 want to move closer to each other along the second direction, the two lower support rods 800 need to be further rotated downward, but the two fourth abutment members 930 contact each other to limit the two lower support rods 800 from further rotating downward, thereby achieving the purpose of limiting the two leg tube assemblies 220 from moving closer to each other along the second direction, so as to further improve the structural stability of the folding table bracket. When the folding table bracket is to be folded, the lower support rods 800 only need to be rotated upward to the unlocked state, which is simple and convenient to operate.

[0049] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
