Description

Technical Field

[0001] The utility model relates to a table which can be folded and stored or unfolded and raised and lowered for use, belonging to the technical field of tables with changeable tabletop heights. Background Art

[0002] With the increasing demand for travel, folding tables are often needed in cars during travel or when camping at destination for gatherings, play, entertainment, or placing food. These are common folding tables.

[0003] Common folding tables, such as the folding table with Chinese patent publication number CN220423394U, generally adopt a foldable and storable table leg design, and even the table leg height is adjustable, so that the table is convenient to unfold and use, and adjust the height. There are also folding lifting tables with Chinese patent publication number CN117837877A, lifting tables with Chinese patent publication number CN218571665U, or outdoor folding tables with Chinese patent publication number CN220494508U, which adopt a cross-structured table leg design, and adjust the tabletop height by adjusting the cross angle, but due to the limited range of the single cross adjustment angle, the overall height of the table is not high, which is not convenient for ground use.

[0004] For a folding table that is more convenient to operate, you can refer to a folding table with Chinese patent publication number CN204561320U or a folding table with Chinese patent publication number CN206380909U, which adopts two sets of upper and lower cross structures to form a scissor mechanism. In this way, the storage height is low after folding, which is convenient for storage and carrying, and the height is high after unfolding, which is convenient for use. However, these two existing tables are not very convenient when unfolding and adjusting the height. The former needs to be turned over to operate the handle of the gas spring, which is inconvenient to operate when used in a small space in a car. The latter has poor adjustment reliability, and the spring force easily causes the desktop to automatically rise, affecting the user experience.

[0005] Therefore, in view of the above shortcomings, it is necessary to design a folding table that is easy to operate and reliable to use and can meet a variety of usage scenarios. Utility Model Content

[0049] The lifting principle of the folding table of the utility model is that the length of the gas spring is changed by bending the operating button; since the mounting seat is fixed to the bottom of the desktop, and the first rod is hinged to the bottom of the desktop, the length of the gas spring between the two is changed, which will push the first rod to swing around the rotation axis, thereby causing the scissor lift table legs to perform a scissor movement; the first rod swings around the rotation axis, driving the hinge pin on the first rod to move, which will drive the second rod to move; the rotation axis at the top of the second rod is rotatably and slidably installed at the bottom of the desktop, and the second rod will swing around the rotation axis and drive the rotation axis to slide; with the swing of the first rod and the second rod, the hinged connection part will also be driven to swing, thereby driving the third rod and the fourth rod hingedly connected together by the hinge pin to move together, and finally realizing the large-distance lifting and lowering movement of the base rod and the base part; the base rod and the base are against the ground, which is finally fed back to the desktop end, realizing the lifting and lowering movement of the desktop.

[0050] The principle of adjusting the length of the gas spring by bending the operating button is that the positions of the gas spring starter rod and the push head of the operating button match. During operation, the button part of the operating button is bent upward to generate action ①, that is, action ② that drives the hinge part to rotate around the pin, so that the push head generates action ③ to move toward the telescopic rod side, and the push head abuts against the end of the starter rod, generating action ④ that presses the starter rod into the telescopic rod, that is, unlocking the gas spring, so that the telescopic rod can be extended or retracted relative to the gas spring cylinder, thereby adjusting the length of the gas spring.

[0051] When the folding table of the utility model is stored, it is in the storage state. At this time, the telescopic rod is retracted into the gas spring cylinder, the length of the gas spring is the shortest, the scissor lift table legs are fully retracted, and the various rods are folded together to reduce the volume, so that the folding table of the utility model is convenient to store and carry.

[0052] When the folding table of the utility model is unfolded for use, the operating button is pushed to trigger the start rod, so that the telescopic rod is extended from the gas spring cylinder, so that the scissor lift table legs are unfolded, thereby raising the table top for use.

[0053] The folding table of the utility model adopts a gas spring, and the unfolding length thereof can be set arbitrarily, so that the folding table of the utility model can be adjusted to any height when in use; and during the adjustment process, the desktop is located at the top, and the foot rod and the foot are located at the bottom, which can always keep in contact with the ground; the height of the desktop can be adjusted by the operator's hand moving the operation button located at the bottom edge of the desktop from the top, and the operation button can be stopped at any time according to the appropriate height, so that the gas spring is locked, that is, the height of the desktop is locked for use, so the height adjustment is convenient and quick.

[0054] When the folding table of the utility model is folded and stored from the use state, it is only necessary to keep the use state, then push the operation button to unlock the gas spring, and then press the table top downward to make the scissor lift table legs fold and shrink until the storage state. The operation process is also simple and efficient.

[0055] The folding table of the utility model is to push the starter rod at the end of the telescopic rod of the gas spring by bending the operation button at the bottom edge of the table top, thereby unlocking the gas spring, changing the length of the gas spring, and finally changing the height of the scissor lift table legs. The operation process of the utility model is simple and convenient, and the height of the table top can be freely adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0093] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0094] The purpose of the utility model is to provide a folding table. Figure 1 As shown, it includes a table top 1 and scissor lift table legs 2; the height of the table top 1 is adjusted by raising and lowering the scissor lift table legs 2.

[0095] Further Figure 2 As shown, one end of the top of the scissor lift table leg 2 is hingedly mounted on one side of the bottom of the desktop 1, and the other end is rotatably and slidably mounted on the other side of the bottom of the desktop 1.

[0096] It also includes a gas spring 3, the gas spring tube end of the gas spring 3 is hingedly installed in the scissor-type lift table leg 2, and one end of the telescopic rod of the gas spring 3 is hingedly installed on the bottom of the desktop 1 through a mounting seat 4; an operating button 5 is hingedly installed in the mounting seat 4; by bending the operating button 5, the starting rod at the end of the gas spring 3 can be triggered, thereby changing the length of the gas spring 3 (making the telescopic rod extend or retract), thereby driving the scissor-type lift table leg 2 to achieve the adjustment of the height of the desktop 1; releasing the operating button 5, the starting rod at the end of the gas spring 3 is reset, the length of the gas spring 3 is locked, and self-locking is achieved, thereby locking the scissor-type lift table leg 2, so that the desktop 1 is stabilized at a fixed height for folding and storage, or use.

[0097] The mounting seat 4 and the operating button 5 are located at the edge of the bottom of the desktop 1. During operation, the operator holds the top of the desktop 1, extends his fingers to the bottom of the desktop 1, and places them on the operating button 5, and then moves the operating button 5 upward to adjust the height of the desktop 1. The entire operation process has no unnecessary movements, is ergonomic, and is convenient and quick to operate.

[0098] When the folding table of the utility model needs to be stored, the operator holds the two sides of the desktop 1 with his hands, and the fingers of one hand bend the operation button 5 upward, so that the start rod is unlocked, and the palms on both sides of the desktop exert force downward together, which can compress the scissor lift table legs 2 downward, so that the telescopic rod retracts into the gas spring cylinder, and the folding, shrinking and deforming of the folding table of the utility model is completed. Preferably, the operation button 5, the mounting seat 4, and the gas spring 3 are located in the middle of the desktop 1, and the palm can be located in the middle of the desktop 1, so that the force is more stable and will not cause the desktop 1 to tilt or overturn; and the overall center of gravity of the folding table of the utility model is also located in the middle, which is more stable and reliable during use.

[0099] like Figure 3 As shown, the lifting mechanism of the utility model mainly includes a scissor lift table leg 2, a gas spring 3, a mounting seat 4, an operating button 5, and a base 6.

[0100] Further references Figure 4 The scissor lift table legs 2 include two groups of double scissor lift mechanisms, each group of double scissor lift mechanisms includes a first rod 22, a second rod 23, a third rod 24, and a fourth rod 25; the middle part of the first rod 22 and the middle part of the second rod 23 are hinged through a hinge pin 26, which are located at the upper part; the middle part of the third rod 24 and the middle part of the fourth rod 25 are hinged through another hinge pin 26, which are located at the lower part; the bottom of the first rod 22 and the top of the third rod 24 are hinged through a hinge connection part 27 located in the middle; the bottom of the second rod 23 and the top of the fourth rod 25 are hinged through another hinge connection part 27 located in the middle.

[0101] A rotating shaft 21 is provided at the top of the first rod 22 and the top of the second rod 23 respectively; wherein the rotating shaft 21 at the top of the first rod 22 is away from the mounting seat 4 and is hingedly installed with the bottom of the desktop 1; the rotating shaft 21 at the top of the second rod 23 is close to the mounting seat 4 and is rotatably and slidably installed with the bottom of the desktop 1 (i.e., it has both a rotating connection and a sliding connection).

[0102] The two sets of double scissor lift mechanisms are respectively located on both sides of the width direction of the desktop 1 and are installed in parallel and symmetrically; and preferably, the two sets of double scissor lift mechanisms are connected together to achieve synchronous lifting; the connection parts of the two sets of double scissor lift mechanisms include a hinged connection part 27 and a base rod 28.

[0103] Among them, the hinged connection part 27 includes a connecting pin 271 and a connecting rod 272; the connecting pin 271 is a long screw rod, which connects the hinged connection parts 27 of the two sets of double scissor lift mechanisms together, that is, it passes through the bottom of the two sets of first rods 22 and the top of the third rod 24, or the bottom of the two sets of second rods 23 and the top of the fourth rod 25 to achieve hinge connection; at the same time, a connecting rod 272 is arranged between the two sets of double scissor lift mechanisms to separate the two sets of double scissor lift mechanisms and provide support.

[0104] The base rod 28 is welded and fixed to the bottom of the third rod 24 or the bottom of the fourth rod 25 of the two sets of double scissor lift mechanisms, and both ends of the base rod 28 extend outward, preferably with the same width as the desktop 1, so as to increase the contact area with the ground and improve the stability of the folding table of the utility model during use.

[0105] Furthermore, the two ends of the base rod 28 are sleeved with base feet 6 to further increase the contact area with the ground and improve the stability of the folding table of the utility model during use.

[0106] The gas spring 3 is located in the middle of the width direction of the table top 1. The gas spring 3 is a self-locking gas spring. Due to the internal structure, it is generally long, so it needs to be hingedly connected with the first rod 22 or the third rod 24; the tail of the gas spring cylinder of the gas spring 3 can be installed in the middle of the connecting rod 272 between the first rod 22 and the third rod 24 through a hinge seat; or, according to the length of the gas spring 3, a mounting rod 29 is set between the first rods 22 on both sides, and the tail of the gas spring cylinder of the gas spring 3 is installed in the middle of the mounting rod 29 through a hinge seat. The mounting rod 29 can further improve the connection stability between the two sets of double scissor lift mechanisms.

[0107] In order to avoid interference after folding, the first rod 22 is located inside the second rod 23 .

[0108] The rod of the scissor lift table leg 2 of the utility model is preferably made of a metal square tube, which can provide sufficient strength and is relatively light, and a sufficient contact plane is formed between the square tubes, which can improve the reliability of the connection of the hinged part. The end of the metal square tube can be covered with a rubber plug, which can improve the aesthetics of the metal square tube and prevent the sharp corners of the end from scratching the operator or other objects.

[0109] like Figure 4As shown, the lifting principle of the folding table of the utility model is that the length of the gas spring 3 is changed by bending the operating button 5; since the mounting seat 4 is fixed to the bottom of the desktop 1, and the first rod 22 is hinged to the bottom of the desktop 1, the length of the gas spring 3 between the two changes, which will push the first rod 22 to swing around the rotating shaft 21, thereby causing the scissor lift table legs 2 to perform a scissor movement; the first rod 22 swings around the rotating shaft 21, driving the hinge pin 26 on the first rod 22 to move, which will drive the second rod 23 to move; the top of the second rod 23 is hinged The movable shaft 21 is rotatably and slidably installed at the bottom of the desktop 1, and the second rod 23 will swing around the rotating shaft 21 and drive the rotating shaft 21 to slide; with the swing of the first rod 22 and the second rod 23, the hinged connection part 27 will also be driven to swing, and then the third rod 24 and the fourth rod 25 hingedly connected together by the hinge pin 26 are driven to move together, and finally the large-distance lifting and lowering movement of the base rod 28 and the base 6 is realized; if the base rod 28 and the base 6 are against the ground, it will eventually be fed back to the end of the desktop 1 to realize the lifting and lowering movement of the desktop 1.

[0110] The surface of the desktop 1 is generally flat and is used for placing objects or performing operations.

[0111] The bottom of the desktop 1 is a structural mounting portion, such as Figure 5 As shown, it mainly includes a folding storage chamber 11 for accommodating the scissor lift table legs 2 and the gas spring 3. On one side of the length direction of the desktop 1, a hinge seat 12 is symmetrically provided along the width direction, and a short cover plate 13 is provided on it through a fastening screw cover to form a space for the rotation shaft 21 of the first rod 22 to be hinged and installed. On the other side of the length direction of the desktop 1, a sliding seat 14 is symmetrically provided along the width direction, and a long cover plate 15 is provided on it through a fastening screw cover to form a space for the rotation shaft 21 of the second rod 23 to be rotated and slidably installed. Generally speaking, the parts of the scissor lift table legs 2 are first welded and assembled to form a whole, and then installed to the bottom of the desktop 1. Therefore, it is necessary to set a short cover plate 13 and a long cover plate 15, and to close the hinge seat 12 and the sliding seat 14 by fastening screws, and to limit the rotation shaft 21. A seat cavity 16 is provided between the sliding seats 14 on both sides, which is used to fix the mounting seat 4 and accommodate the operation button 5.

[0112] like Figure 6 , Figure 7 As shown, the mounting seat 4 is fixed in the seat cavity 16; after the operation button 5 is installed in place on the mounting seat 4, the operation button 5 is basically flush with the solid part of the desktop 1 outside the seat cavity 16, so as to prevent the operation button 5 from being too protruding and thus being triggered by mistake. The gas spring 3 includes a gas spring cylinder 31, which is far away from the mounting seat 4, and a hinge seat 32 is provided at the bottom of the gas spring cylinder 31; a telescopic rod 33 is provided in the gas spring cylinder 31, and the end of the telescopic rod 33 is hingedly installed in the mounting seat 4.

[0113] One of the key points of improvement of the folding table of the present invention is the structure of the mounting seat 4 and the operating button 5 .

[0114] The specific structure of the mounting base 4 is as follows: Figure 8-12 As shown; for easy installation, the mounting base 4 is composed of a mounting base 41 and a mounting cover 42. After the covers are put together, they are fixed together by fastening screws 43; the mounting base 4 includes two mounting cavities, which are used to install the end of the telescopic rod 33 and the operation button 5 respectively.

[0115] Specifically, the mounting base 41 has a complex structure and is generally injection molded, including a base body 411, one side of the base body 411 is an articulated mounting seat for the telescopic rod 33, and the other side is an articulated mounting seat for the operating button 5; wherein, the articulated mounting seat side of the telescopic rod 33 has an upper opening 412 for the telescopic rod 33 to pass through, and an upper articulated seat 413 for articulation, and the upper articulated seat 413 is provided with two locations, which are coaxially arranged; wherein, the articulated mounting seat side of the operating button 5 has a pin shaft 416 for mounting the operating button 5, and the pin shaft 416 can be a steel shaft, which is inserted into the base body 411 from the outside and passes through the operating button 5 when assembled with the operating button 5.

[0116] The telescopic rod 33 of the base body 411 is hinged on the mounting seat side, and is also provided with a positioning hole 414 and a light hole 415; the lower sides of the base body 411 protrude outward to form mounting ears 418, and the mounting ears are provided with mounting holes 419, which are preferably long and adjustable holes.

[0117] like Fig.19 As shown, the mounting seat 4 is installed in the seat cavity 16 through the mounting ear 418, and the fastening screw 44 passes through the mounting hole 419 and is tightened on the entity at the bottom of the desktop 1 through the mounting ear 418.

[0118] Preferably, a retaining bar 417 is provided on the hinged mounting seat side of the operating button 5 of the base body 411 , and the retaining bar 417 is preferably arranged parallel to the pin shaft 416 .

[0119] The mounting cover 42 can also be formed by injection molding, and includes a cover body 421. The cover body 421 has a lower opening 422 for the telescopic rod 33 to pass through, and a lower hinge seat 423 for hinge connection. The lower hinge seat 423 is provided at two locations and is coaxially arranged. The cover body 421 is also provided with a positioning column 424 and a mounting hole 425.

[0120] The mounting cover 42 is installed on the side of the mounting base 41 where the telescopic rod 33 is hingedly mounted. The positioning column 424 is inserted into the positioning hole 414 to position the mounting cover 42 and the mounting base 41. Then, the light hole 415 is aligned with the mounting hole 425. The fastening screw 43 is inserted from the outside of the light hole 415 of the mounting base 41. The fastening screw 43 passes through the light hole 415 and is screwed into the mounting hole 425. The mounting cover 42 is fixed to the mounting base 41 to form the mounting base 4. At this time, the upper opening 412 and the lower opening 422 are put together to form an opening for the telescopic rod 33 to pass through. Preferably, the opening is a vertically arranged long strip, which can be used to adjust the position of the telescopic rod 33 when it swings. The upper hinge seat 413 and the lower hinge seat 423 are put together to form an hinge seat for the hinged installation of the telescopic rod 33.

[0121] The specific structure of the operation button 5 is as follows: Fig.13 , Fig.14 As shown, the longitudinal section ( Fig.14 The key 51 is in an "L" shape, the long side of the "L" shape is the button part 51, the short side of the "L" shape is the push head part 52, and the connection between the button part 51 and the push head part 52 is a hinge part 53, which is provided with a hinge hole. Preferably, the button part 51 has a larger area and is in an arc shape to better fit the curvature of the finger. The push head part 52 needs to effectively push the start rod, so the strength requirement of the operation button 5 is relatively high, and it can be made of metal or high-strength engineering plastic.

[0122] like Fig.15 , Fig.16 As shown, the operation button 5 is hingedly installed in the mounting base 41 of the mounting seat 4, and the pin shaft 416 passes through the hinge part 53 to form a hinged installation; the blocking bar 417 is located on the outside of the push head part 52 (away from the telescopic rod 33) to limit the operation button 5.

[0123] The gas spring 3 is generally a standard part, and the telescopic rod 33 side is generally shipped in the form of a screw. The telescopic rod 33 is hingedly installed in the mounting seat 4. Fig.17 , Fig.18 As shown, it is necessary to install an articulated shaft seat 36 on the screw end 34 of the telescopic rod 33; the articulated shaft seat 36 includes a mounting body 361, and a mounting hole 362 is provided in the mounting body 361. The mounting hole 362 can be a light hole (such as Fig.18 As shown), it can also be a threaded hole, which is sleeved or screwed on the screw end 34; a hinge shaft body 363 is provided on both sides of the mounting body 361; a nut 37 is provided on one side or both sides of the hinge shaft seat 36.

[0124] When the mounting hole 362 is a threaded hole, the hinge shaft seat 36 itself is screwed onto the screw end 34 , and the hinge shaft seat 36 can be locked onto the screw end 34 by only one nut 37 .

[0125] However, since the angles of the telescopic rod 33 and the screw end 34 relative to the gas spring cylinder 31 are difficult to adjust, and when the hinge shaft seat 36 is screwed on the screw end 34, the angle of the hinge shaft body 363 and the installation position are difficult to adjust; Fig.17 , Fig.18 As shown, the mounting hole 362 is a smooth hole, and nuts 37 are provided on both sides of the articulated shaft seat 36. The articulated shaft seat 36 is fixed to the screw end 34 through the nuts 37. The position of the articulated shaft seat 36 can be adjusted by adjusting the position of the nuts 37, and the angle of the articulated shaft seat 36 itself can be freely adjusted.

[0126] like Fig.19 As shown, during assembly, the hinge shaft seat 36 is first fixed to the screw end 34 of the telescopic rod 33 by the nut 37, and then the hinge shaft seat 36 is installed into the mounting base 41 of the mounting seat 4, so that the hinge shaft body 363 falls into the upper hinge seat 413; then the mounting cover 42 is covered, and the hinge shaft seat 36 together with the telescopic rod 33 and the screw end 34 are hingedly installed in the mounting seat 4.

[0127] Further Fig. 20 As shown, after the operation button 5 and the telescopic rod 33 are installed in place in the mounting seat 4, the end of the start rod 35 protrudes outward in a natural state and presses against the surface of the push head 52 of the operation button 5; by adjusting the nut 37, the position of the hinge shaft seat 36 can be adjusted, thereby adjusting the distance between the end of the start rod 35 and the push head 52 to ensure that the positions of the start rod 35 and the push head 52 match. At this time, the button portion 51 of the operation button 5 is bent upward to produce action ①, that is, action ② that drives the hinge portion 53 to rotate around the pin 416, so that the push head 52 produces action ③ that moves toward the side of the telescopic rod 33, and the push head 52 abuts against the end of the start rod 35, producing action ④ that presses the start rod 35 into the telescopic rod 33, that is, unlocking the gas spring 3, so that the telescopic rod 33 can be extended or retracted relative to the gas spring cylinder 31.

[0128] When the finger leaves the button portion 51 of the operating button 5, the start rod 35 will automatically reset and extend, thereby pushing the push head portion 52 toward the blocking bar 417, thereby driving the button portion 51 of the operating button 5 to reset downward. At this time, the length of the gas spring 3 is locked.

[0129] The bottom of the gas spring cylinder 31 of the gas spring 3 is generally provided with a mounting ear with a hole, which can be connected to the hinge seat 32; Figure 21-24As shown, the hinge seat 32 includes a U-shaped seat 321, and the two sides of the U-shaped seat 321 are vertical to form hinge ears 3211, and the middle is a mounting cavity 3212; the hinge ears 3211 on both sides are respectively provided with hinge holes 3213; and also include a hinge pin 322; the perforated mounting ear of the gas spring cylinder 31 is inserted into the mounting cavity 3212 of the U-shaped seat 321, and the hinge pin 322 passes through the hinge hole 3213 on one side, the mounting hole on the mounting ear of the gas spring cylinder 31, and the hinge hole 3213 on the other side from the outside of the hinge ear 3211 on one side, in turn, to hinge the bottom of the gas spring cylinder 31 on the U-shaped seat 321.

[0130] The U-shaped seat 321 can be pre-welded and fixed on the mounting rod 29. Fig.24 As shown, the mounting cavity 3212 is relatively wide, allowing the mounting ears of the gas spring cylinder 31 to adjust their positions in the hinge seat 32 .

[0131] In order to further improve the stability of the folding table during use, the four corners of the horizontally arranged foot rod 28 at the bottom of the scissor lift table leg 2 are respectively installed with foot 6, and the specific structure is as follows: Figure 25-28 As shown, the foot 6 is composed of two parts, namely a foot rod sleeve 61 and a foot seat 62, both of which are rubber or plastic parts; the foot rod sleeve 61 is sleeved and fixed on the end of the foot rod 28, including a mounting and fixing hole 611; the outside of the foot rod sleeve 61 is a cylindrical adjusting column 612, and both ends of the adjusting column 612 are provided with limiting bodies 613; the foot seat 62 is provided with a ground contact plane 621, and an adjusting cylinder 622 is provided above the ground contact plane 621, and the adjusting cylinder 622 is sleeved on the adjusting cylinder 612, so that the foot seat 62 is rotatably installed on the foot rod sleeve 61; the limiting body 613 can limit the adjusting cylinder 622.

[0132] Preferably, a slot 623 is provided on the top of the adjusting cylinder 622 , so that the adjusting cylinder 622 can be symmetrically split, and the walls on both sides are elastic, so that it can be easily mounted on the adjusting column 612 .

[0133] Further preferably, the diameter of the adjusting cylinder 622 is preferably slightly smaller than the diameter of the adjusting column 612, so that the adjusting cylinder 622 is elastically sleeved on the adjusting column 612, so that the two can rotate relative to each other, but there is rotational damping.

[0134] During the use of the folding table of the present invention, as the scissor lift table legs 2 are unfolded, the angle of the base rod 28 will change, driving the angle of the base rod sleeve 61 to change. At this time, the base seat 62 and the base rod sleeve 61 rotate to ensure that the ground contact plane 621 is always in contact with the ground, thereby increasing the contact area and improving the stability of the folding table of the present invention during use.

[0135] like Fig.29 , Fig.30 As shown, the folding table of the present invention is in the storage state, at this time, the telescopic rod 33 is retracted into the gas spring cylinder 31, the length of the gas spring 3 is the shortest, the scissor lift table legs 2 are fully retracted, and the various rods are folded together to reduce the volume, thereby making the folding table of the present invention convenient to store and carry.

[0136] like Fig.31 , Fig.32 As shown, this is the first state of the folding table of the utility model. By pushing the operating button 5, the starting rod 35 is triggered, and the telescopic rod 33 is extended from the gas spring cylinder 31 for a distance, so that the scissor lift table legs 2 are unfolded, so that the table top 1 is raised for a distance, such as about 20 cm, for use as a cushion.

[0137] like Fig.33 , Fig.34 As shown, this is the second state of the use process of the folding table of the utility model. By pushing the operating button 5, the starting rod 35 is further triggered, and the telescopic rod 33 is further extended from the gas spring cylinder 31, so that the scissor lift table legs 2 are further unfolded, so that the table top 1 is further raised by a distance, such as about 40 cm, so that it can be used in a low sitting state.

[0138] like Fig.35 , Fig.36 , Fig.37 As shown, the folding table of the utility model is in a fully unfolded state. By pushing the operation button 5, the start rod 35 is continuously triggered, and the telescopic rod 33 is fully extended from the gas spring cylinder 31, so that the scissor lift table legs 2 are fully unfolded, so that the table top 1 is raised to the highest point, generally up to 70cm-80cm, and can be used as a table of normal height. At this time, the bottom rod 28 of the scissor lift table legs 2 is biased toward the side of the table top 1 close to the hinge seat 12, but it can still ensure that the bottom rods 28 on both sides are located on both sides of the midline of the length direction of the table top 1, thereby ensuring the stability of the table top 1 during use.

[0139] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope defined by the claims of this application.
