Description

Technical Field

[0001] The utility model relates to the field of learning tools, in particular to a single-body sitting posture corrector. Background Art

[0002] Because children are naturally active and inattentive, it is difficult for them to maintain a correct sitting posture. Over time, they will develop bad habits such as leaning forward, lowering their heads, or resting their chins on their hands. At this time, most parents will consider using a sitting posture corrector to correct their children's bad sitting habits.

[0003] However, existing single-body correctors generally focus on one-way height adjustment (flexible lifting and lowering of the legs), while ignoring the defects of the barrier plate (chest plate). The distance between the barrier plate and the chest cannot be flexibly adjusted, causing the user to lean forward to use it, causing discomfort to the user and even affecting normal learning. The usual solution is to move the stool inward to facilitate contact between the chest and the barrier plate to maintain the blocking state. However, existing desks and stools are mostly one-piece structures. Such stools cannot be moved forward, causing children to become overly resistant to leaning forward and even simply not use the sitting posture corrector. Summary of the Invention

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] It should be noted that the terms "upper side", "lower side", "inner side", "outer side", "one side", "center" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0017] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "set," "fixed," "connected," etc., should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms can be understood in specific circumstances.

[0018] Please refer to Figure 1 The length and width of the clamping base are 11 cm and 8 cm respectively. The clamping base includes an upper plywood 1 and a lower plywood 4. The upper plywood 1 and the lower plywood 4 have the same specifications. A circular socket 2 that matches the plug 7 is provided in the center of the upper side of one side of the two plywoods. A cylindrical column hole 3 is provided at both ends of the lower side of one side of the upper plywood 1. The column hole 3 does not penetrate the upper side of the upper plywood 1 at the corresponding position. A notch is provided horizontally on the lower side of the other side of the upper plywood 1; a cylindrical limiting column 5 that matches the inner cavity of the column hole 3 is vertically provided at both ends of the upper side of one side of the lower plywood 4, and a notch is provided horizontally on the upper side of the other side of the lower plywood 4.

[0019] The length, width and depth of the two notches are equal. The thickness of one side and the other side of the two splints are 1.8 cm and 1 cm respectively. The height of the limiting column 5 is greater than half the thickness of the upper splint 1.

[0020] The column hole 3 and the limiting column 5 have the following benefits: by embedding and limiting, the upper clamping plate 1 and the lower clamping plate 4 will not slide or shift, and they will always maintain a closely connected working state, which is beneficial to the stability of the clamping base.

[0021] It should be noted that the two sockets 2 both pass through the lower side of the corresponding clamping plates.

[0022] It should be noted that the position of the limiting column 5 is the same as the position of the column hole 3.

[0023] During actual operation, the upper splint 1 and the lower splint 4 are aligned and stacked together, and then the limiting pillars 5 are inserted into the limiting position. After the limiting position, the upper splint 1 is always in close contact with the lower splint 4.

[0024] During actual operation, the socket 2 on the upper clamping plate 1 is aligned with and overlaps the socket 2 on the lower clamping plate 4 .

[0025] Please refer to Figure 2 A movable arm 11 is horizontally provided on the upper part of one side of the support 6, and a blocking plate 13 is provided on the outer side of one end of the movable arm 11. A cylindrical plug 7 with a screw is vertically provided on the lower side of the support 6. The outer diameter of the lower part of the support 6 is larger than the inner diameter of the socket 2. The outer diameter of the plug 7 is equal to the inner diameter of the socket 2. The plug 7 is equipped with a matching six-sided screw sleeve 8.

[0026] Support 6: The support 6 has a lifting function. The support 6 can adjust the blocking plate 13 to a height suitable for reading or writing, which is beneficial to the students' vision health.

[0027] The support 6 is composed of an outer sleeve and an adjustment inner tube. A horizontal plane is set from the upper part to the lower part of one side of the outer sleeve. The horizontal plane is formed by removing the curvature of the outer wall of one side of the outer sleeve, which does not affect the integrity of the inner circle of the outer sleeve. An elliptical fixing sleeve is provided on one side (plane) of the outer sleeve, and a limiting mechanism 9 made of PC material is provided in the fixing sleeve on one side of the outer sleeve.

[0028] A horizontal plane is set from the upper part to the lower part of one side of the adjusting inner tube. The horizontal plane is formed by cutting off the curvature of the outer wall of one side of the adjusting inner tube, which does not affect the integrity of the inner circle of the adjusting inner tube. Linear grooves 10 are evenly set on both sides of one side (plane) of the adjusting inner tube from top to bottom. After the adjusting inner tube is movably connected with the outer sleeve, it is clamped and limited by the limiting mechanism 9.

[0029] Movable arm 11: The movable arm 11 has the function of flexible extension and contraction. By adjusting the movable arm, the distance between the blocking plate 13 and the human chest can be reduced to achieve the actual effect of effectively blocking the chest, so that students can always maintain an upright posture when reading and writing, which is conducive to developing correct sitting habits.

[0030] The movable arm 11 is composed of a square outer tube and an inner telescopic tube. A limiting mechanism G14 is provided on the plane of one side of the outer tube. Linear grooves G12 are evenly provided on both sides of the plane of one side of the inner telescopic tube. After the inner telescopic tube and the outer tube are movably connected, they are clamped and limited by the limiting mechanism G14.

[0031] In fact, the movable arm 11 and the support 6 belong to the same structure, but the tube shape is different. The outer sleeve of the support 6 is equivalent to the outer tube, and the adjustment inner tube of the support 6 is equivalent to the inner telescopic tube.

[0032] In fact, the structures and working principles of the limiting mechanism G14 and the limiting mechanism 9 are exactly the same.

[0033] Blocking plate 13: The blocking plate 13 is also called chest baffle, which is mainly used to block the chest of the human body, so that students can read or write in the correct sitting posture, which is conducive to developing good sitting habits.

[0034] The baffle 13 is composed of a hard silicone baffle and a soft silicone pad. The silicone pad is arranged on one side of the baffle (towards the chest side of the human body). The soft silicone pad is suitable for flexible contact with the chest of the human body and has a comfortable feeling.

[0035] Please refer to Figure 3The upper splint 1 is aligned with the lower splint 4 and closed, the two limit columns 5 are respectively embedded in a column hole 3, the support 6 is vertically movable and arranged in the center of the upper side of one side of the clamping base, and the plug 7 passes through the socket 2 on the upper side of one side of the two splints and is then tightened and fixed by the screw sleeve 8.

[0036] The advantage of the plug 7 is that it connects the two splints in series, plays the role of central auxiliary reinforcement limit, and can effectively improve the stability of the corrector.

[0037] For the purpose of in-depth understanding, the drawings of this embodiment only focus on showing one side of the corrector (the side facing the desk 20) ​​so that the positions of the various components can be clearly seen.

[0038] Please refer to Figure 4 The limiting mechanism 9 is composed of an extrusion head 16, a pressure rod 17 and a clamp 19. The extrusion head 16 is movably arranged in a circular opening at the lower part of one side of the plate frame 15. The outer circle of the cylindrical pressure rod 17 is provided with a spring 18. One end of the pressure rod 17 is fixed in the empty opening on the inner side of one side of the extrusion head 16, and the other end of the pressure rod 17 is fixed to the lower part of one side of the clamp 19. After one end of the upper part of the clamp 19 passes through the strip opening on the corresponding side of the outer sleeve, it is clamped in the slot 10 on the side of the adjustment inner tube. The clamp 19 is a 7-shaped structure.

[0039] In fact, the entire limiting mechanism 9 is arranged in a fixed sleeve on one side of the outer sleeve.

[0040] The function of the spring 18 is to drive the pressure rod 17 to reset outward through elastic potential energy, so that the upper part of the clamping member 19 is quickly embedded in the clamping groove 10 on one side of the adjustment inner tube, and finally achieve the actual effect of limiting.

[0041] Working principle of the clamp 19: The outward warping of the upper part of the clamp 19 follows the lever principle of the ancient Greek scientist Archimedes. By applying pressure to one end of the clamp 19, the other end is tilted, thereby achieving the actual effect of flexible limiting.

[0042] The working principle of the limiting mechanism 9 is: when the extrusion head 16 is pressurized, the pressure rod 17 will squeeze the lower part of the card 19 inward, and when the lower part of the card 19 is pressurized, its upper part will warp outward and break away from the adjustment inner tube. At this time, the user can flexibly adjust the height of the support 6; when the user's finger leaves the extrusion head 16, the elastic potential energy of the spring 18 will prompt the pressure rod 17 to reset outward, and when the lower part of the card 19 loses pressure, the upper part of the card 19 will quickly embed inward and get into the corresponding slot 10. At this time, the adjustment inner tube is limited.

[0043] Since the limiting mechanism 9 and the limiting mechanism G14 have the same working principle, the limiting mechanism G14 will not be described in detail in this embodiment.

[0044] Please refer to Figure 5 The fact is, correct sitting posture can keep the child's spine in normal physiological curve, prevent problems such as myopia and scoliosis, and at the same time, it can promote blood circulation and improve learning efficiency.

[0045] Overall installation process: 1. Clamp the outer edge of one side of the desk 20 panel with the clamp on one side of the clamp base; 2. Pass the plug 7 at the bottom of the support 6 through the socket 2 inside one side of the clamp base and tighten it with the screw sleeve 8; 3. After adjusting the height of the support 6, adjust the distance between the barrier plate 13 and the human chest as required; 4. Start reading or writing.

[0046] It should be noted that when the panel of the desk 20 is relatively thick, a partial space can be appropriately opened between the upper clamping plate 1 and the lower clamping plate 4 to increase the height in the clamping opening.

[0047] Correction working principle: 1. The user sits upright and puts both hands around the clamp base; 2. Adjust the length of the movable arm 11 as required so that the chest of the user contacts the silicone pad; 3. The user's chin hangs in the recessed area on the upper side of the barrier plate 13; 4. Start reading or writing.

[0048] The greatest advantage of this embodiment is that: by adjusting the movable arm 11, the distance between the blocking plate 13 and the human chest is reduced to achieve the actual effect of effective blocking, so that students can always maintain an upright posture when reading and writing; by increasing the distance between the two splints to increase the height inside the clamping mouth, the corrector can be installed on a desk 20 with a thicker panel, thereby improving the flexibility of installation.
