Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of building construction technology, specifically for a kind of anti-misoperation switch and lifting foot stool. BACKGROUND

[0002] Building indoor construction refers to various building decoration and reconstruction work carried out in indoor environment, aiming to create comfortable, beautiful and fully functional indoor environment. Its main contents include wall treatment, ground laying, ceiling installation, water and electricity line layout, kitchen and bathroom equipment device etc.

[0003] When carrying out ceiling installation, water and electricity line layout and other constructions, it is necessary to use auxiliary construction device with certain height to improve its height and better carry out construction. Due to the limitation of indoor space, auxiliary construction device is generally foot stool, ladder etc.

[0004] Traditional foot stool generally has moving and lifting functions, but construction personnel needs to move or lift foot stool frequently, which is more complicated to use. SUMMARY

[0005] Traditional foot stool has moving and lifting functions, but moving and lifting adjustment needs to be carried out frequently by workers, which is more complicated to use. After searching, an automatic lifting foot stool controlled by controller is found in medical field, which solves the above problems, but it is not suitable for indoor construction. In order to solve the above problems, an anti-misoperation switch and lifting foot stool are proposed in the embodiment of the application.

[0006] An anti-misoperation switch comprises a button and a shell containing at least one button, the shell comprises a first arc-shaped part, and the tangent of any point on the curve of the surface of the two ends of the first arc-shaped part forms an angle with the horizontal line, and the maximum value range of the angle is 60°-70°.

[0007] The first arc-shaped part further comprises a first side and a second side, and the first side and the second side are fixedly arranged or limitingly arranged, and the first side and the second side are arranged vertically.

[0008] Beneficial effect: the first side of the first arc-shaped part is fixed or limited with the inner side surface of the baffle installed in the opposite direction of the opening, so that the arc surface of the first arc-shaped part faces the opening, and the button is installed on the top of the first arc-shaped part close to the baffle. When in use, the worker needs to lift his toes. Since the maximum value of the included angle between the tangent of any point on any curve on the surface of the first arc-shaped part and the horizontal line is 60°-70°, the worker needs to make the angle between the sole and the horizontal plane reach at least ° when lifting his toes, so that the arch of the foot is contracted, and then the toe contacts the button at the top of the first arc-shaped part, and then the heel is lifted to press the button. At this time, the calf muscles are obviously tightened, ensuring that the worker can clearly perceive that he is operating when adjusting, avoiding misoperation during operation.

[0009] The shell comprises a second arc-shaped part and a third arc-shaped part, the second arc-shaped part and the third arc-shaped part are an integral structure, and the second arc-shaped part and the third arc-shaped part further comprise a third side and a fourth side, the third side and the fourth side are fixedly arranged or limitedly arranged, and the third side and the fourth side are arranged perpendicularly.

[0010] The maximum value of the included angle between the tangent of any point on any arc line on the surface of the second arc-shaped part and the horizontal line is 60°-70°, and the maximum value of the included angle between the tangent of any point on any arc line on the surface of the third arc-shaped part and the horizontal line is 30°-45°.

[0011] A lifting foot stool comprises a lower support plate and an upper support plate arranged in parallel in the vertical direction.

[0012] The lifting foot stool comprises at least one lifting component arranged between the lower support plate and the upper support plate, and the two ends of the lifting component are fixedly arranged or limitedly arranged on the lower support plate and the upper support plate. A plurality of lifting components can be arranged between the upper support plate and the lower support plate to realize different functions, and the shapes of the corresponding lower support plate and upper support plate can also be changed.

[0013] Specifically, when only one lifting component is arranged, the lifting foot stool has only one telescopic electric cylinder or hydraulic cylinder and the corresponding equipment, which can further reduce the weight and enhance the portability, facilitating the workers to carry.

[0014] Specifically, when one lifting component is arranged, the area of the lower support plate and the upper support plate needs to be expanded, so that the volume of the lifting foot stool as a whole is increased, but the use of multiple lifting components improves the load capacity of the foot stool, so that the workers can carry more loads to work.

[0015] Specifically, when installing the lifting component, the lifting component can be evenly distributed at the four corners or four sides of the upper support plate, and is matched with the pressure plate installed on the surface of the upper support plate; when performing the construction operation, the control component calculates the current center of gravity position of the construction personnel by receiving the pressure data from the pressure plate, and lifts the different heights by using the lifting component at the four corners or four sides, so that the upper support plate forms a certain inclination angle with the horizontal plane to assist the construction personnel in construction, and the inclination caused by the center of gravity deviation is prevented.

[0016] The mobile component is arranged below the lower support plate.

[0017] As shown in the drawings, the anti-misoperation switch is arranged at least two fixed positions or limiting positions on the surface of the upper support plate; the anti-misoperation switch is electrically connected with the lifting component and the mobile component; the anti-misoperation switches arranged at different positions have different triggering effects according to the use habit, including specific lifting and moving.

[0018] The anti-misoperation switch includes a button and a shell accommodating the button; the traditional handheld controller is integrated into the upper surface of the upper support plate, and the difference from the traditional automatic lifting footstool is that the construction personnel directly steps on the button, so that the construction personnel can directly adjust the height of the footstool and control the movement of the footstool during the operation without interrupting the construction, so that the overall construction efficiency is further improved.

[0019] Specifically, the periphery of the upper support plate is further provided with a baffle, the baffle is fixedly connected or movably connected with the periphery of the upper support plate, the baffle semi-surrounds the upper support plate, and an opening is formed on the upper support plate, and the opening is oriented towards the heel of the construction personnel during the operation.

[0020] Specifically, when the maximum value range of the included angle formed by the tangent of any point on any curve on the surface of the two ends of the first arc-shaped part and the horizontal line is less than 60°, during the operation, some construction personnel will unconsciously rely on or put their feet on the first arc-shaped part, which may cause the button to be mispressed, so that the lifting footstool moves without the construction personnel knowing, and the construction personnel falls.

[0021] Specifically, when the maximum value range of the included angle formed by the tangent of any point on any curve on the surface of the two ends of the first arc-shaped part and the horizontal line is greater than 70°, when the pressing action is performed, the position of the button exceeds the maximum angle that the tip of the foot can be lifted without lifting the heel, and the construction personnel needs to lift the whole sole to press the button, which will cause the construction personnel to be distracted or slip on the arc-shaped surface of the first arc-shaped part during the operation, and the construction personnel falls.

[0022] Specifically, the second arc-shaped part is installed at the baffle of the opening side, and can be installed in the range of rotating left or right with the heel of one foot as the center for the convenience of use; specifically, when the second arc-shaped part is installed at the inner side of the human palm, it is more convenient for the operator to press the button, but the upper surface of the upper support plate is divided into two areas, thereby reducing the activity range of the operator; specifically, when the second arc-shaped part is installed at the outer side of the human palm, the central positions of the upper surface of the upper support plate are connected in one piece, so that the operator has a larger activity range, but the operator needs to rotate the palm first and then press the button when pressing the button, which is relatively cumbersome.

[0023] Specifically, the maximum value range of the included angle formed by the tangent of any point on the surface of the second arc-shaped part and the horizontal line is 60°-70°, when the second arc-shaped part is installed at the outer side of the human palm, the operator is blocked by the second arc-shaped part when moving towards the second arc-shaped part with the heel as the center, prompting the operator to lift the toe for pressing, and further prompting the operator that the position is being adjusted, thereby avoiding falling.

[0024] Specifically, when two buttons are installed in the shell, the two buttons are connected in series, and the operator needs to step on the two buttons at the same time to trigger the corresponding movement, thereby further improving the safety.

[0025] One side of the lower support plate is fixedly provided or limitingly provided with a stepping plate.

[0026] The upper surface of the upper support plate is provided with at least one pressure plate, the pressure plate is electrically connected with the control unit, the surface of the upper support plate and the stepping plate is provided with anti-skid lines, and the lower support plate is further connected with a handle.

[0027] The lifting component is a telescopic electric cylinder or a telescopic hydraulic cylinder and a power supply.

[0028] The moving component comprises an omnidirectional wheel or a universal wheel and a motor.

[0029] Compared with the prior art, the utility model has the following beneficial effects:

[0030] 1. Safe and anti-misoperation setting

[0031] Anti-misoperation switch ergonomic optimization: the tangent inclination angle of the shell arc-shaped part, i.e. the first arc-shaped part, is limited to 60°-70°, so that the operator needs to lift the heel, the arch of the foot is contracted, and the calf muscle is tightened, so as to trigger the button and avoid accidental lifting or moving caused by misoperation.

[0032] Angle verification: if the angle is < 60°, misoperation is easily triggered due to natural leaning of the foot;

[0033] If the angle is greater than 70 degrees, it is necessary to lift the foot excessively, causing distraction or slipping risk. Dynamic adjustment of the center of gravity:

[0034] Through the linkage of the lifting components distributed at the four corners of the upper support plate and the pressure plate, the platform inclination angle is adjusted in real time to prevent the center of gravity from shifting and tipping over.

[0035] 2. Operation efficiency is improved

[0036] Integrated control setting: The trigger button is integrated on the surface of the upper support plate, so that the height or movement can be adjusted without interrupting the construction during operation, reducing the operation steps.

[0037] 3. Multi-scenario adaptability:

[0038] Supporting 1-4 lifting components for flexible configuration:

[0039] 1 lifting component: lightweight and portable, suitable for single person short-time operation;

[0040] 1-2 lifting components: enhance the load capacity (such as multi-person cooperation) or realize intelligent leveling function.

[0041] 3. Structure optimization and reliability enhancement

[0042] Anti-slip and protection settings:

[0043] Anti-slip patterns are set on the surface of the upper support plate and the step plate to reduce the risk of slipping;

[0044] Half-enclosed baffle limits the displacement range of the feet, improving the stability of the operation.

[0045] Emergency safety guarantee:

[0046] Setting the handle for manual movement when power is off, and as a fence to prevent falling.

[0047] 4. Precision of human-computer interaction

[0048] Multi-angle shell layout:

[0049] The second circular arc part (60°-70°) and the third circular arc part (30°-45°) are combined to consider the foot operation range and accidental touch protection, and to adapt to different foot action habits (such as internal rotation / external rotation trigger).

[0050] 5. Maintenance and mobility convenience

[0051] Omni-directional wheels or universal wheels: support flexible movement in multiple directions, reducing the burden of manual carrying;

[0052] Modular power supply and lifting components: use telescopic electric cylinders or hydraulic cylinders to reduce maintenance complexity. BRIEF DESCRIPTION OF DRAWINGS

[0065] Specifically, when two to three lifting components are installed, the area of the lower support plate 101 and the upper support plate 102 needs to be expanded, so that the volume of the whole lifting foot stool increases, but the use of multiple lifting components improves the load capacity of the foot stool, enabling the construction personnel to carry more load for work.

[0066] Specifically, when four lifting components are installed, the lifting components can be evenly distributed at the four corners or four sides of the upper support plate 10, and at the same time, the pressure plate 11 installed on the surface of the upper support plate 10 is matched, during the construction work, the control component receives the pressure data from the pressure plate 11, calculates the current center of gravity position of the worker, and uses the lifting components at the four corners or four sides to lift to different heights, so that the upper support plate 10 forms a certain inclination angle with the horizontal plane to assist the worker in construction, preventing the center of gravity from shifting and causing the stool to fall.

[0067] The mobile component is arranged below the lower support plate 101. Embodiment 2

[0068] As shown in Figure 3 on the basis of embodiment 1, at least two anti-misoperation switches are fixedly arranged or positionally arranged on the surface of the upper support plate 102; the anti-misoperation switches are electrically connected with the lifting components and the mobile component; the anti-misoperation switches installed at different positions set different triggering effects according to the use habit, including specific lifting and moving.

[0069] The anti-misoperation switch includes a button 10 and a housing 9 accommodating at least one button 10; the traditional handheld controller is integrated into the upper surface of the upper support plate 102, and the difference from the traditional automatic lifting foot stool is that the construction personnel directly step on the button, and the construction personnel can directly adjust the height of the foot stool and control the movement of the foot stool during the work process without interrupting the construction, so that the overall construction efficiency is further improved.

Specifically, when the second arc-shaped part 903 is installed on the inner side of the human palm, it is more convenient for the operator to press the button 10, but the upper surface of the upper support plate 102 is divided into two areas, reducing the activity range of the operator; Specifically, when the second arc-shaped part 903 is installed on the outer side of the human palm, the center positions of the upper surface of the upper support plate 102 are connected to form a whole, so that the operator has a larger activity range, but the operator needs to rotate the palm first and then press the button when pressing the button, which is relatively cumbersome.

[0077] Specifically, the maximum value range of the included angle formed by the tangent of any point on the surface of the second arc-shaped part 903 and the horizontal line is 60°-70°, when the second arc-shaped part 903 is installed on the outer side of the human palm, the operator is blocked by the second arc-shaped part 903 when moving to the second arc-shaped part 903 with the heel as the center, reminding the operator to lift the toe for pressing, and further reminding the operator that the position is being adjusted to avoid falling.
