Description

Technical Field

[0001] The invention relates to the technical field of furniture, in particular to a tea drinking stool with an adjustable V-shaped stool surface height and angle. Background Art

[0002] Some customers have reported that traditional tea chairs are heavy wooden chairs that are expensive, large in size, and cannot accommodate many people. They were unable to find seating in the exhibition hall that was suitable for the company's corporate culture and was suitable for receiving and drinking tea with employees.

[0003] Many stools used for drinking tea are square, which looks uncoordinated when placed in front of a large tea table. It is also easy for the stools to shift seriously. After drinking tea, staff often have to come and rearrange the stools.

[0004] Take a common armchair on the market as an example. It uses an upright steel pipe to support the seat, which can rotate left and right. There is also a spring system between the steel pipe and the seat to allow the seat to rock back and forth, allowing people to reach a semi-lying state. However, these armchairs usually look not lively enough when placed in front of a tea table.

[0005] Many offices are occupied by young employees. We need to design a tea stool that is novel in shape, comfortable to sit on, with uniform sitting posture within a certain range, and does not require people to place it neatly, so that employees can drink tea, coffee or sit for a while. Our designed product has a sense of ceremony in modern office spaces, is simple, bright and comfortable, and makes people even willing to hold several office meetings in front of the tea table.

[0006] Ordinary stools do not have the function of adjusting the inclination of the stool board. In terms of sitting posture, they cannot provide the sitter with a deep or shallow sitting state, and the comfort level cannot satisfy most people. Many ladies choose a shallow sitting posture, and it is best to adjust an adjustment bolt quickly to change the angle of the stool board to make it flat. Many men enjoy a slightly deep sitting posture, adjusting the angle of the stool board backwards, and leaning their waist against the back board.

[0007] When drinking tea, people usually face the tea table, and they don't often whisper to each other. The person sitting does not need to rely on the left and right swing of the stool to change the left and right turn of the body. Slightly turning the shoulders to communicate with the companions around is also an elegant behavior, which deserves mutual appreciation.

[0008] We found that the use of channel steel can replace the traditional round steel pipe support for the stool surface, and just does not provide the stool surface with the action of shaking left and right, and can well adjust the front and back angles. After adjustment, the stool surface angle is relatively static. Aesthetically, the structure of channel steel has a more metallic texture and meets modern aesthetic values. At present, there is no use of channel steel to make tea stools, and there is no combination of two sections of channel steel to adjust the angle of the tea stool surface. For this reason, we want to produce a tea stool that is not easy to shift, does not need to rotate left and right, has an adjustable V-shaped stool surface, and has a light and luxurious shape. Summary of the invention

[0009] In order to achieve this purpose, the present invention provides a method for adjusting the height and angle of a V-shaped stool surface of a tea drinking stool. The method uses two sections of grooved steel of different sizes to form a stool surface support groove and a support groove inclined sleeve to form and adjust the height and tilt angle of a V-shaped stool surface of a tea drinking stool. The tea drinking stool made by the method has the following structural processing from bottom to top:

[0010] 1. The lower part of the tea stool:

[0011] a. The frame-type stool foot is made of a plane frame composed of a square iron pipe, and a supporting groove oblique sleeve made of a groove-shaped steel material is arranged to be obliquely erected upward, with the groove opening downward, and the groove bottom edge and two groove wings at the bottom end thereof are welded to the middle upper surface of the rear side of the frame-type stool foot, and the lower ends of the two oblique sleeve reinforcing support rods are welded to the front upper surface of the frame-type stool foot, and the upper ends of the two oblique sleeve reinforcing support rods are welded to the outer sides of the upper parts of the two groove wings of the supporting groove oblique sleeve;

[0012] 2. Middle part of tea stool:

[0013] b. Choose the groove in the support groove oblique sleeve that is closest to a square, and the outer diameter of the stool surface support groove is slightly smaller than the inner diameter of the support groove oblique sleeve;

[0014] c. A notched U-shaped iron plate is provided at the notch of the upper part of the support slot inclined sleeve, which is buckled on the outside of the two slot wings of the support slot inclined sleeve and welded firmly to form a local accommodating square frame; in the same notch direction as the support slot inclined sleeve, the stool surface support slot is inserted into the support slot inclined sleeve;

[0015] d. A round hole is set in the center of the notch U-shaped iron plate, a nut is welded on the inner side of the round hole, and an adjusting bolt is screwed into the nut to vertically pass through the notch U-shaped iron plate to push up the bottom edge of the stool surface support groove;

[0016] e. A round hole is set at the back of the bottom of the support groove inclined sleeve, a nut is welded on the outside of the round hole, and a locking bolt is screwed into the support groove inclined sleeve through the nut to press the back of the stool surface support groove downward;

[0017] f. At the lower end of the bench surface support groove, there is a lower hole of the support groove. At the middle and lower parts of the two wing edges of the support groove sleeve, there are multiple height adjustment holes. A bolt passes through one of the height adjustment holes and the lower hole of the support groove to adjust the height of the bench surface support groove from the ground. The top of the bench surface support groove is fixedly connected to the bench board;

[0018] III. Upper part of the tea-drinking bench:

[0019] g. At the middle of the lower side of the bench board, a rear baffle installation elbow is fixed with bolts. The rear baffle installation elbow turns upwards behind the bench board, and at its top, there is a rear baffle installation hole bending towards the bench surface. The rear baffle is installed onto the rear baffle installation hole through a connecting piece with bolts, anti-slip washers, and nuts.

[0020] The beneficial effects of the present invention are as follows: achieving the effects of making the tea-drinking bench novel in style, simple in structure, and with a large range of adjustable V-shaped bench surface height and angle. Description of the drawings

[0028] The above numbers do not follow the sequence of the structural names of the present invention. Detailed implementation manners

[0029] As a matching seat for a new type of tea-drinking table we plan to launch, it includes six, eight or more of the same type of tea-drinking stools placed in front of and on both sides of the tea-drinking table, eliminating the need to constantly worry about the displacement of the placement position of the tea-drinking stools. It is also difficult to achieve a very neat placement effect when tidying up, which slightly affects the united spirit of the company. Tea-drinking is a tradition, a courtesy and facade of the company's leadership, and also a way for the company team to get together. Our solution is to use channel steel with a strong metallic texture for manufacturing, giving a very alert feeling. Moreover, the tea-drinking stools are fixed on the left and right and do not rotate. They have a V-shaped seat surface with adjustable height, and both the rear baffle and the seat board can be adjusted in angle, being serious yet lively.

[0030] The present invention aims to provide a new style of tea-drinking stool, achieving the effects of novel style, simple structure, and adjustable height and angle of the V-shaped seat surface in a large range.

[0031] The method for adjusting the height and angle of the V-shaped seat surface of the adjustable tea-drinking stool described in the present invention means that there is a V-shaped seat surface on the upper part of the tea-drinking stool in the present invention. The V-shaped seat surface is composed of a rear baffle 1 and a seat board 2, and an angle similar to a V shape is formed between them. The angle and height of the V-shaped seat surface are adjustable, and the inclination of the rear baffle of the V can be adjusted by itself, collectively referred to as "adjustable height and angle of the V-shaped seat surface". In this design, the rear baffle 1 is not a backrest, but a baffle above the buttocks and below the waist circumference. The seat board 2 tends to be flat. The distance between the seat board 2 and the rear baffle 1 is a few centimeters, and they are close to being connected, forming an L-shaped angle with a smaller upper side and a longer bottom side of the groove, or a V shape with an angle greater than 90 degrees, which we call a V shape and can also be regarded as a ✔ shape. In this way, people can enjoy a deep sitting posture on the tea-drinking stool. The height and angle adjustment of the aforementioned seat surface are at different positions, and the orientation of the seat surface is still fixed and neat.

[0032] Different from the common structure of using a single round tube to support the seat surface, the support of the V-shaped seat surface in our design is achieved by a support groove bevel sleeve 7 that stands up and inclines forward and a seat surface support groove 9 that is sleeved inside in the same notch direction. The groove-shaped structure that plays a supporting role is called the support groove; the seat surface support groove 9 is the groove-shaped structure that supports the V-shaped seat surface; the support groove bevel sleeve 7 is the groove-shaped structure that obliquely stands and sleeves the "seat surface support groove 9". Both the seat surface support groove 9 and the support groove bevel sleeve 7 are made of channel steel, which is a metal structure with a long bottom side of the groove and two long groove wings perpendicular to the bottom side of the groove. The outer sides of the two groove wings are parallel, and the inner sides of the groove wings are either parallel or nearly parallel in some cases, and not parallel in others. We preferably choose the former. The support rod bevel sleeve 7 is larger than the seat surface support groove 9, and their bottom sides of the grooves are in contact, and the wings are also in contact, with a certain gap and can be separated.

[0033] The part between the parallel lines along the long edges of the two channel wings of the channel steel is what we call the notch. For the bench surface support groove 9, the force acts in the direction of the front notch. A sufficiently thick U-shaped iron plate 13 for the notch is welded in the notch direction, which is buckled on the outer sides of the two channel wings of the support groove bevel sleeve 7 and welded firmly to form a firm local square surrounded area, called the accommodation square frame. The bench surface support groove 9 can move back and forth inside it to change the angle of the bench surface.

[0034] The lower hole 2 of the support groove is a round hole at the lower part of the bench surface support groove 9, at the lower part inside the support groove bevel sleeve 7. There are height adjustment holes 6 on the two channel wings at the lower part of the support groove bevel sleeve 7, and bolts pass through them. Taking this as the fulcrum, the upper part of the bench surface support groove 9 moves between the upper edge of the upright and forward-tilting support groove bevel sleeve 7 and the aforementioned U-shaped iron plate 13 for the notch, so that the V-shaped bench surface fixedly connected to the upper end of the bench surface support groove 9 can change its position in the front-back direction.

[0035] By changing the vertical position where the U-shaped iron plate 13 for the notch is welded on the outer sides of the two channel wings of the aforementioned "support groove bevel sleeve 7", the forward-tilting amplitude of the bench surface support groove 9 can be changed.

[0036] By changing the position of the lower hole 2 of the support groove at the lower part inside the support groove bevel sleeve 7, the vertical position of the bench surface support groove 9 in the support groove bevel sleeve 7 can be changed.

[0037] The main problems to be solved by the present invention are as follows: the strength of the channel steel, how to make it using the channel steel, and the adjustable range.

[0038] Channel steel is also called U-channel steel. U-channel steel is a hot-rolled section steel, and its detailed dimensions and mechanical properties have formed national standards. The national standard document refers to GB / T707-1988. Its sizes range from No. 5 to No. 40, and it is usually abbreviated or simply called C steel in factories. Because channel steel has good mechanical properties, it is widely used in mechanical engineering, but it is less used in the application of tables and chairs.

[0039] The channel steel selected for the present invention is used for the support groove bevel sleeve 7 and the bench surface support groove 9. Theoretically, two types can be fully and satisfactorily selected from the aforementioned channel steel specifications. One is used as the bench surface support groove 9. Since the length of the bench surface support groove 9 is short, a channel steel of a smaller size model can meet the use requirements; one is used as the support groove bevel sleeve 7, which is larger than the model of the bench surface support groove 9. Cooperating with the bevel sleeve reinforcing strut 4, its support strength requirement also meets the design requirement of bearing 80 kg.

[0040] The present invention provides an experimental data, which is reference data obtained from a sample manufacturer and does not represent a certain product that will be recognized by the market. Refer to Figure 1It is marked that: the width of the inclined sleeve reinforcing strut 4 is 4 cm, and the thickness is 1.5 mm to 2.5 mm; the width of the frame-shaped stool leg 5 is 3 cm and the thickness is 1.5 to 4 mm; the width of the support groove inclined sleeve 7 is 4 cm and the thickness is 2 to 4 mm; the width of the stool surface support groove 9 is 3.5 cm and the thickness is 1.5 to 4 mm; the width of the rear baffle mounting crank 10 is 2.5 cm and the thickness is 1.5 to 2.5 mm. If new tests are carried out subsequently and the experimental data change, the data that best meets the market needs shall prevail. In principle, the better the material, the larger the width and the larger the thickness, the more solid it is, and it also appears more luxurious, but the cost is also higher. This is selected according to the requirements of customers and the market.

[0041] Combined with the identification of each component in the various drawings of the present invention, the implementation method of the present invention is to use two channel steels of different sizes to make the stool surface support groove 9 and the support groove inclined sleeve 7 to form and adjust the height and inclination angle of a V-shaped stool surface of a tea-drinking stool. The structure of the tea-drinking stool made by this method is processed as follows from bottom to top.

[0042] I. Lower part of the tea-drinking stool:

[0043] a. The frame-shaped stool leg 5 is made into a planar frame composed of square iron pipes. A support groove inclined sleeve 7 made of channel steel is set to stand obliquely upward with the groove opening downward. The bottom groove bottom edge and two groove wings of it are welded to the upper surface in the middle of the rear side of the frame-shaped stool leg 5. Also, the lower ends of the two inclined sleeve reinforcing struts 4 are welded to the upper surface of the front side of the frame-shaped stool leg 5, and the upper ends of the two inclined sleeve reinforcing struts 4 are welded to the outer sides of the upper parts of the two groove wings of the support groove inclined sleeve 7.

[0044] II. Middle part of the tea-drinking stool:

[0045] b. Select the groove in the support groove inclined sleeve 7 that is closest to a square shape, and the outer diameter of the stool surface support groove 9 is slightly smaller than the inner diameter of the support groove inclined sleeve 7.

[0046] c. At the groove opening of the upper part of the support groove inclined sleeve 7, a U-shaped iron plate 13 with a groove opening is provided, which is buckled on the outer sides of the two groove wings of the support groove inclined sleeve 7 and welded firmly to form a partial accommodating square frame; in the same groove opening direction as the support groove inclined sleeve 7, the stool surface support groove 9 is sleeved into the support groove inclined sleeve 7.

[0047] d. A round hole is provided in the center of the U-shaped iron plate 13 with a groove opening, and a nut is welded to the inner side of the round hole. An adjusting bolt 3 is screwed into the nut and vertically passes through the U-shaped iron plate 13 with a groove opening to push up the bottom groove edge of the stool surface support groove 9.

[0048] e. A round hole is provided behind the bottom groove of the support groove inclined sleeve 7, and a nut is welded to the outside of the round hole. A locking bolt 8 is also screwed into the support groove inclined sleeve 7 through the nut to press down the back of the groove of the stool surface support groove 9.

[0049] f. At the lower end of the stool surface support groove 9, a support groove lower hole 12 is provided. At the middle and lower parts of the two wing edges of the support groove inclined sleeve 7, a plurality of height adjustment holes 6 are provided. A bolt passes through one of the height adjustment holes 6 and the support groove lower hole 12 to adjust the height of the stool surface support groove 9 from the ground. The top end of the stool surface support groove 9 is fixedly connected to the stool board;

[0050] III. Upper part of the tea-drinking stool:

[0051] g. At the middle of the lower side of the stool board 2, a rear baffle mounting elbow 10 is fixed with bolts. The rear baffle mounting elbow 10 turns upward behind the stool board 2, and a rear baffle mounting hole 11 bent towards the stool surface is provided at its top end;

[0052] h. At the middle position of the rear part of the rear baffle 1, a connecting piece is provided, which is formed by combining a U-shaped small steel sheet and an iron plate. The bottom edge of the U-shaped small steel sheet is welded to the center position of the iron plate. There are four bolt holes on the iron plate and are fixed to the back of the rear baffle 1 with screws; The two wings of the U-shaped small steel sheet are perforated, and it is installed onto the rear baffle mounting hole 11 with bolts, anti-slip washers and nuts.

[0053] Following the above design, a tea-drinking stool with a simple structure and a large adjustable range for the height and angle of the V-shaped stool surface is formed.

[0054] In order to more clearly illustrate the solutions provided by the embodiments of the present invention, some additional explanations for each drawing are given separately as follows.

[0055] Figure 1 This is a schematic diagram of the overall side view structure of the tea-drinking stool of the present invention.

[0056] The stool surface support groove 9 is smaller than the support groove inclined sleeve 7. The outer diameter of the stool surface support groove 9 is smaller than the inner diameter of the support groove inclined sleeve 7, so that the bottom edge of the groove of the stool surface support groove 9 can be tightly attached to the bottom edge of the groove of the support groove inclined sleeve 7 and can move but not be too loose.

[0057] The design of using channel steel is for a new aesthetic effect, taking into account the cost, and also preventing the stool surface from rotating randomly in the left and right directions.

[0058] The round hole labeled 12 in the figure represents the bolt head or bolt of the support groove lower hole 12 leaking out outside the support groove inclined sleeve 7.

[0059] The support groove inclined sleeve 7 is fixed and non-adjustable. With the support groove lower hole 12 as the fulcrum, the upper end of the stool surface support groove 9 can move back and forth at the upper position of the channel steel of the stool surface support groove 9, thereby realizing the front and rear tilt angles of the stool board 2.

[0060] There is a fixed support bar between the stool board 2 and the stool surface support groove 9, and the angle between them is fixed and non-adjustable. The angle between them is solidified during the design. This angle ensures that within the maximum and minimum amplitudes of the forward and backward movement of the stool surface support groove 9 with the bottom hole of the stool surface support groove 9 as the origin, the stool board 2 maintains a change amplitude greater than the horizontal angle, so as to meet the maximum requirement for adjusting comfort.

[0061] The V-shaped stool surface has an adjustable angle, including the angle at which the adjustable stool board 2 inclines upward on a plane, and the vertical angle of the rear baffle 1 can be adjusted, mainly relying on the angle adjustment of the stool surface support groove 9. The angle of the rear baffle 1 can also rely on the connecting piece arranged at the middle position of the rear part of the rear baffle 1. The connecting piece is composed of the combination of a U-shaped small steel sheet and an iron plate. The bottom edge of the U-shaped small steel sheet is welded to the center position of the iron plate. There are four bolt holes on the iron plate and are fixed to the back of the rear baffle 1 with screws; the two wings of the U-shaped small steel sheet have holes. The U-shaped small steel sheet wraps around the upper end of the installation elbow 10 of the rear baffle, and bolts pass through the two holes of the U-shaped small steel sheet and the installation hole 11 of the rear baffle, and are tightened with anti-slip washers and nuts.

[0062] As Figure 1 、 Figure 2 、 Figure 3 shown, the rear baffle 1 of the present invention is not used as the backrest of a chair. It is different from a backrest chair, but the rear baffle 1 is only at a distance of a few centimeters from the stool board 2 and does not provide backrest relaxation, aiming to make the shoulders of all sitters more consistent. Adjusting the shape of this stool can better conform to the sitting postures and comfort preferences of each person.

[0063] The inclined sleeve strengthening struts 4 are two parallel components of the same style, which play a role in stabilizing the support groove inclined sleeve 7. They are welded to the outer sides of the two wings in the upper middle part of the support groove inclined sleeve 7, and are in a state of clamping the front half of the middle part of the support groove inclined sleeve 7. After welding, through the overall plastic spraying process, the shape can achieve the designed aesthetic effect.

[0064] Figure 2 This is a front view overall structure schematic diagram of the tea stool of the present invention.

[0065] Combined with Figure 2 and Figure 5 it can be known that due to the reason of the illustrated angle, the rear part of the frame-shaped stool leg 5 in the figure is not drawn. In fact, the bottom end of the support groove inclined sleeve 7 is connected to the upper plane of the rear part of the frame-shaped stool leg 5.

[0066] The angle between the stool surface support groove 9 and the stool board 2 is fixed. As Figure 1 shown, there is also strengthened support at the connection between the stool surface support groove 9 and the stool board 2.

[0067] As in the conventional connection method, the upper end of the stool support groove 9 is a cut surface with a suitable angle, which is welded together with a piece of iron plate. This iron plate is larger and has four holes, which are locked into the corresponding embedded nut positions under the stool plate 2 with four bolts.

[0068] In appearance, the channel steel of the same size and thickness has one less side than the square tube, and its mechanical strength will be weaker. However, if the channel steel is larger and thicker than the square tube, its strength can exceed that of the square tube.

[0069] Since the bottom edge of the groove of the groove steel is much thinner than the thickness of the whole iron pipe, the range of movement of the stool surface support groove 9 in the accommodating frame formed by a support groove oblique sleeve 7 can be maximized, and the structure of the support groove oblique sleeve 7 can be minimized.

[0070] Figure 3 It is a schematic diagram of the stool surface of the tea stool of the present invention.

[0071] In this design, the bench board 2 and the back guard board 1 are both multi-layer plywood.

[0072] The rear baffle mounting bend 10 is a single bent or tilted component, and on the middle vertical line of the rear side of the bench board 2, its uppermost end has a portion bent toward the bench surface, and the portion is provided with a circular hole in the left and right directions.

[0073] The round holes on the bench board 2 and the rear baffle 1 are designed for ventilation and also for aesthetic appearance.

[0074] Figure 4 It is a schematic diagram of adjusting the inclination of the support groove of the stool surface of the tea stool of the present invention.

[0075] The support groove oblique sleeve 7 is welded to the rear of the frame-type stool foot 5, and the welding position has a groove wing of the support groove oblique sleeve 7 which is linearly reduced. This is for the purpose of welding the lower side of the groove wing to the frame-type stool foot 5 neatly, and also for the aesthetics of the shape.

[0076] The present invention relates to bolts, and bolts of different lengths of ten centimeters can be used. The bolt consists of a head and a rod. The head of the bolt in the present invention is provided with a large knob, which is convenient for rotating the bolt rod left and right.

[0077] The stool surface support groove 9 can be lifted up and down in the support groove oblique sleeve 7. We designed a round hole at the lower end of the stool surface support groove 9, called the support groove lower hole 12. The round hole numbered "12" in the figure represents the head or nut of the bolt that leaks out of the support groove lower hole 12 outside the support groove oblique sleeve 7.

[0078] The lower hole portion of the support slot with black oblique stripes shows the situation when the lower hole 12 of the support slot coincides with the height adjustment hole 6 on the oblique sleeve 7 of the support slot, and the rod of the bolt can pass through at this time.

[0079] CombinationFigure 4 , Figure 1 As shown, by changing the vertical position of the notched U-shaped iron plate 13 welded to the "outer sides of the two groove wings of the support groove inclined sleeve 7", the inclination amplitude of the stool surface support groove 9 can be changed, and the inclination amplitude of the stool board 2 in the V-shaped stool surface can be changed.

[0080] In the figure, it shows that the bolt at the adjustment bolt 3 abuts against the bottom edge of the groove of the support groove inclined sleeve 7 because the stool surface support groove 9 is also a channel steel, and the thickness of the bottom edge of the groove is relatively thin. In the figure, the locking bolt 8 is also screwed in the least. At this time, the stool surface support groove 9 is in the state of being pushed into the highest angle.

[0081] As can be seen from the figure, the method of sleeving the stool surface support groove 9 into the support groove inclined sleeve 7 in the same groove direction is the best way to adjust in the present invention.

[0082] Before the stool surface support groove 9 is inserted into the support groove inclined sleeve 7, a metal pad sleeve is put on the front end of the rod portion of the adjustment bolt 3. The pad sleeve makes the combination of the bolt front end and the stool surface support groove 9 tighter, and the adjustment bolt is also more labor-saving;

[0083] Figure 5 This is the structural diagram of the frame-shaped stool legs of the tea-drinking stool of the present invention.

[0084] Figure 5 It shows the cross-section of the support groove inclined sleeve 7 as a channel steel. The shape is also as shown in the cross-section of the support groove inclined sleeve 7 in the figure. The support groove inclined sleeve 7 uses a profile with a thicker bottom, longer and slightly thinner two groove wings, meeting the requirements of being strong enough and beautiful.

[0085] As Figure 5 shown, the bottom ends of the stool surface support groove inclined sleeve 7 and the inclined sleeve reinforcing strut 4 are respectively in the relative front and back on the frame-shaped stool legs 5. The frame-shaped stool legs 5 are a hollow iron pipe frame structure surrounded by square iron pipes, and can be welded by iron pipes that are wider at the back, slightly narrower at the front, and narrower on both sides. It can also be bent from a whole thicker iron pipe in a right-angle bending manner, and finally, the joints are welded.

[0086] The inclined sleeve reinforcing strut 4 is a strip-shaped metal, using square iron pipes or channel steels.

[0087] As also shown in the figure, the frame-shaped stool legs 5 are large enough, and generally, the situation of a person sitting on the stool and tipping over will not occur.

[0088] To make the tea-drinking stool stable and not easily displaced when pushed, the frame-shaped stool legs 5 are appropriately enlarged in terms of the size and thickness of the iron pipes. Larger anti-slip rubber gaskets are also installed at the four corners of the bottom of the frame-shaped stool legs 5. Two round holes that are first large and then small are also provided at the bottom of the anti-slip rubber gasket, and are locked into the bottom of the frame-shaped stool legs 5 with flat head screws.

[0089] Generally, the height of the tea-drinking stool has been adjusted during purchase and installation and does not need to be frequently adjusted during daily use. To make an adjustment, remove the bolt from the height adjustment hole 6, align the bottom hole of the stool surface support groove with another height adjustment hole 6, and then insert the bolt.

[0090] The operation method for adjusting the "stool board height" of the V-shaped stool surface of the present invention:

[0091] a. Remove the bolt from the height adjustment hole 6, place the stool surface support groove 9 into the groove of the support groove inclined sleeve 7. According to the height that the stool surface support groove 9 needs to reach, align the lower hole 12 of the support groove with the selected height adjustment hole 6, pass the bolt through and install the nut, and the up-and-down height of the stool surface support groove 9 is also fixed. When it is necessary to re-adjust the height of the stool surface support groove 9, repeat the above steps.

[0092] The operation method for adjusting the "stool board angle" of the V-shaped stool surface in the present invention:

[0093] a. When it is necessary to increase the angle of the stool surface support groove 9, first loosen the locking bolt 8, screw in the adjustment bolt 3 to make the stool surface support groove 9 move backward.
