Description

Technical Field

[0001] This utility model relates to a workstation stool, and more particularly to a height-adjustable workstation stool. Background Technology

[0002] In various production workplaces, stools are commonly used auxiliary tools for operators. If operators stand for long periods of time while performing various production and processing tasks, it will lead to accumulated fatigue in the legs and waist. A suitable stool can provide support for operators, thereby reducing fatigue and improving their comfort while working. This allows operators to maintain high efficiency for longer periods of time. In work environments that require precise operations, such as electronic assembly and machining, stools can provide more stable support for operators during processing, improving the accuracy of processing operations.

[0003] Existing workstation benches are usually of a fixed height. For operators of different heights and for different processing scenarios, such as different workstations on battery production lines where the height of the work surface varies, fixed-height benches cannot meet the corresponding support needs of operators, causing inconvenience to operators' daily work, affecting work efficiency and the health of operators. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a height-adjustable workstation stool. The operator can adjust the locking mechanism by locking it into the slots at different heights connected to the support column. The support column and the positioning block connected to the bottom of the support column slide on the limiting plate and the stool leg, respectively, changing the vertical height of the support column. The stool surface rises and falls with the height of the support column, realizing a simple and quick adjustment of the height of the workstation stool, improving the practicality and versatility of the workstation stool and the operator's working comfort.

[0005] This utility model is achieved through the following technical solution:

[0006] A height-adjustable workbench includes a seat and legs. The legs include two legs 1 and two legs 2. A support column is vertically connected to the center of the bottom surface of the seat. A limit plate is slidably connected to the support column. The tops of legs 1 and 2 are alternately and equidistantly connected to the bottom edge of the limit plate. A positioning block is vertically connected to the bottom surface of the support column. The positioning block is slidably connected to the two legs 1. A locking device is rotatably connected to the legs 2. The locking end of the locking device is movably connected to the side of the support column. Stabilizing rings parallel to the limit plate are connected to legs 1 and 2 near the foot of the seat.

[0007] Furthermore, the support column includes a column body, a slot, and a guide rail, and the height of the column body is equal to the vertical distance between the limiting plate and the stabilizing ring.

[0008] Furthermore, the slots are connected equidistantly in the vertical direction to the side of the column opposite to the second stool leg, and the guide rail is connected vertically to the side of the column opposite to the first stool leg.

[0009] Furthermore, the limiting plate is a circular plate-shaped structure parallel to the bottom surface of the stool. A limiting hole is vertically inserted through the center of the top surface of the limiting plate. The cross-sectional shape of the limiting hole is the same as the maximum cross-sectional shape of the support column. The limiting plate is slidably connected to the support column through the limiting hole.

[0010] Furthermore, the vertical heights of stool leg one and stool leg two are equal, stool leg one is perpendicular to the bottom surface of the limiting plate, and stool leg two is tilted ten degrees in the opposite direction to the center of the bottom surface of the limiting plate, relative to the direction perpendicular to the limiting plate.

[0011] Furthermore, a vertically penetrating limiting hole is connected to the top surface of the positioning block at a position directly opposite the first stool leg. The cross-sectional shape of the limiting hole is the same as the horizontal cross-sectional shape of the first stool leg. The positioning block is slidably connected to the first stool leg through the limiting hole.

[0012] Furthermore, the locking mechanism is rotatably connected at a position one-eighth of the length downward from the top of the second stool leg. The length of the locking mechanism is greater than the horizontal distance from the rotatable connection to the support column, and less than the distance from the rotatable connection to the connection between the limiting plate and the support column.

[0013] Furthermore, the shape of the locking end of the clip is adapted to the shape of the slot, and the locking end of the clip engages in the slot at a horizontal height above the rotating connection.

[0014] Compared with the prior art, this utility model has the following obvious advantages:

[0015] I. This utility model includes two stool legs, namely two stool legs 1 and two stool legs 2. The tops of stool legs 1 and 2 are alternately and equidistantly connected to the bottom edge of the limiting plate. Stool legs 1 are perpendicular to the limiting plate, and stool legs 2 are inclined at ten degrees in the opposite direction to the center of the bottom surface of the limiting plate relative to the direction perpendicular to the limiting plate. The vertical heights of stool legs 1 and 2 are equal, and a stabilizing ring parallel to the bottom surface of the limiting plate is connected near the stool foot. This can maintain the stability of the bottom of the workstation stool and achieve stable support for the stool surface.

[0016] II. Due to the sliding connection of the vertical hole connecting the support column and the limiting plate, and the sliding connection of the positioning block connected to the bottom of the support column and the stool leg, this utility model can maintain the horizontal limitation of the stool surface and the support column connected to the stool surface when the stool surface moves, thus limiting the stable movement of the stool surface and the support column in the vertical direction.

[0017] Third, this utility model has vertically equidistant slots connected to the side of the support column opposite to the second stool leg. The second stool leg is rotatably connected to a locking device. The shape of the locking end of the locking device is adapted to the shape of the slot. After the operator changes the vertical position of the stool surface and the support column, the locking device is locked in the slot at the corresponding height, and the support stool surface and the support column are positioned on the second stool leg, thereby limiting the position of the stool surface and the support column after the stool surface height is changed.

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a height-adjustable workstation stool, including a stool surface 1, a support column 2, a positioning block 3, a limiting plate 4, stool legs 1 5, stool legs 2 6, a clip 7, and a stabilizing ring 8. In this embodiment, the bottom surfaces of the stool surface 1, the limiting plate 4, the positioning block 3, and the stabilizing ring 8 are parallel to each other and arranged sequentially from top to bottom along the vertical central axis of the support column 2. The stool legs include two stool legs 1 5 and two stool legs 2 6. The tops of stool legs 1 5 and stool legs 2 6 are alternately and equidistantly distributed and connected to the bottom edge of the limiting plate 4. The vertical heights of stool legs 1 5 and stool legs 2 6 are equal. The limiting plate 4 is a circular plate structure. Stool legs 1 5 are perpendicular to the bottom surface of the limiting plate 4, and stool legs 2 6 are tilted 10 degrees in the opposite direction to the center of the bottom surface of the limiting plate 4 relative to the direction perpendicular to the limiting plate 4. The stabilizing ring 8 is connected to stool legs 1 5 and stool legs 2 6 near the stool feet.

[0024] The support column 2 is vertically connected to the center of the bottom surface of the stool surface 1. The support column 2 includes a column body 201, a slot 202, and a guide rail 203. The height of the column body 201 is equal to the vertical distance between the limiting plate 4 and the stabilizing ring 8. The slots 202 are connected equidistantly in the vertical direction to the side of the column body 201 opposite to the stool leg 6. The guide rail 203 is vertically connected to the side of the column body 201 opposite to the stool leg 5. A limiting hole is vertically inserted through the center of the top surface of the limiting plate 4. The maximum cross-sectional shape of the support column 2 is the same as the cross-sectional shape of the limiting hole. The support column 2 is slidably connected to the limiting plate 4 through the limiting hole. The positioning block 3 is vertically connected to the bottom of the support column 2. On the top surface of the positioning block 3, a vertically penetrating limiting hole is connected at a position directly opposite the stool leg 5. The cross-sectional shape of the limiting hole is the same as the horizontal cross-sectional shape of the stool leg 5. The positioning block 3 is slidably connected to the stool leg 5 through the limiting hole. The clamp 7 is rotatably connected at a position one-eighth of the length downward from the top of the stool leg 6. The length of the clamp 7 is greater than the horizontal distance from the rotatable connection to the support column 2 and less than the distance from the rotatable connection to the edge of the penetrating hole connected to the limiting plate 4. The shape of the clamping end of the clamp 7 is adapted to the shape of the slot 202. The clamping end of the clamp 7 is engaged in the nearest slot 202 above the horizontal height of the rotatable connection.

[0025] The working principle of this utility model is as follows:

[0026] When this utility model is in use, the initial state of the workstation stool is that the locking piece 7 is locked in the slot 202 at the highest position connected to the side of the support column 2, and the stool surface 1 is at the lowest height position. When the operator needs to raise the height of the stool surface 1, the operator grabs the stool surface 1 and pulls it vertically upward. The stool surface 1, support column 2 and positioning block 3 rise vertically under the limiting action of the limiting plate 4 and the stool leg 5. The locking piece 7 slides out from the uppermost slot 202. After the operator raises the stool surface 1 to the appropriate height position, he releases the stool surface 1. As the support column 2 falls back, the locking piece 7 locks into the nearest slot 202 above the locking end. The stool leg 6 and the locking piece 7 support and limit the position of the stool surface 1 and support column 2 in the vertical direction, thus completing the adjustment of the stool height.

[0027] If the height of the seat surface 1 is too high after adjustment and needs to be lowered, the operator first releases the locking end of the locking piece 7 from the locking slot 202, rotates the locking piece 7 to move the locking end of the locking piece 7 away from the support column 2, and manually controls the seat surface 1 and the support column 2 to descend. When the seat surface 1 descends to the appropriate position, the operator rotates the locking piece 7 so that the locking end of the locking piece 7 engages with the nearest locking slot 202 at the same horizontal height. The seat legs 2 6 and the locking piece 7 support and limit the position of the seat surface 1 and the support column 2 in the vertical direction, thus completing the adjustment of the seat height.

They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
