[0028] See also Figure 1-6 The present invention provides a technical solution: a rapid assembly method for a mortise and tenon structure staircase, comprising the following steps:

[0029] Step 1: Place several processed stair treads 29 on the equidistant adjustment assembly, and adjust the spacing and inclination angles between the stair treads 29 according to installation requirements;

[0030] Step 2: Place the side panel 32 horizontally on the docking assembly. The docking assembly adjusts the side panel 32 to a suitable height and pushes the side panel 32 and the stair panel 29 to dock.

[0031] Step 3: Fix the side panels 32 on both sides of the staircase 29 by mortise and tenon joints through the docking assembly to complete the quick assembly of the stairs;

[0032] Step 4: Remove the assembled stairs from the equidistant adjustment component, and repeatedly replace the stair treads 29 and the side panels 32 to continue assembling.

[0033] As a further solution of the present invention, a rapid assembly device for a mortise and tenon structure staircase includes an equidistant adjustment component and a docking component. The equidistant adjustment component includes a fixed frame 3, on which a plurality of sliding plates 2 distributed at equal distances are slidably connected. The bottom of the sliding plate 2 is rotatably connected to a roller 13, and the plurality of sliding plates 2 are rotatably connected to a transmission frame 9. The transmission frame 9 is slidably sleeved with a limit frame 10, and the limit frame 10 can drive the various components of the transmission frame 9 to rotate synchronously so that each sliding plate 2 slides equidistantly. The top of the sliding plate 2 is rotatably connected to a rotating plate 11, and the rotating plate 11 is fixedly connected to a support plate 1 for placing a stair plate 29. One end of the rotating plate 11 is fixedly connected to a first rotating shaft 15, and a swing transmission mechanism is provided on the first rotating shaft 15. The swing transmission mechanism is used to control each rotating plate 11 to rotate at the same angle and is not affected by changes in the spacing between the sliding plates 2;

[0034] When the above scheme is put into actual use, the processed stair treads 29 are placed on the support plate 1 above the sliding plate 2, and the spacing between each stair tread 29 is determined according to the size of the stairs. By pressing down or pulling up the limit frame 10, the transmission frame 9 is driven to extend and retract as a whole, and the sliding plates 2 are controlled to slide and adjust the spacing on the fixed frame 3 through the rollers 13. The limit frame 10 can keep each sliding plate 2 sliding at an equal distance during the sliding process, so that the spacing of each stair tread 29 is the same after adjustment. After the spacing adjustment is completed, the first rotating shaft 15 is rotated to adjust the angle of the support plate 1 so that the protrusion 30 on one side of the stair tread 29 can be docked with the groove 31 on one side of the side plate 32. The mortise and tenon joint is completed internally, and the first rotating shaft 15 is transmitted through the swing transmission mechanism during rotation, so that each support plate 1 can achieve the same amplitude of rotation, thereby realizing the control of equal-angle rotation of all support plates 1. After the adjustment of the stair plate 29 is completed, the two sets of side panels 32 are fixed from both sides of the stair plate 29 through the docking assembly, and then slowly pushed to the position where the protrusion 30 docks to complete the docking, thereby completing the rapid splicing of the stairs. The advantage of this is that for stairs of the same specifications processed in batches, the spacing angle needs to be adjusted during the initial docking. The subsequent mortise and tenon-jointed stairs of the same specifications only need to be placed on the equipment and pushed to complete the splicing, which can greatly improve the efficiency of stair splicing.

[0035] As a further solution of the present invention, the docking assembly includes a screw rod 5, which is rotatably arranged at one end of a fixed frame 3, and a drive motor 12 is fixedly connected to the side wall of the fixed frame 3. The output end of the drive motor 12 passes through the fixed frame 3 and is fixedly connected to the screw rod 5. A slide 4 is spirally connected to the screw rod 5, and a hydraulic mechanism 6 is fixedly connected to the top of the slide 4. A fixed plate 8 is fixedly connected to the output shaft of the hydraulic mechanism 6. Both ends of the fixed plate 8 are respectively slidably connected to a clamping frame 7, and a servo motor for driving the clamping frame 7 to slide is fixedly connected to the bottom of the fixed plate 8;

[0036] After the stair tread 29 is in the position of being fixed at the height of the engagement groove 31, the two side panels 32 are respectively placed on the two fixing plates 8, noting that the card slot 31 faces the end of the protrusion 30, and the two side panels 32 are fixed by the clamping frames 7 on both sides. The driving motor 12 is started to drive the screw rod 5 to rotate, pushing the slide plate 4 to slide in the direction of the stair tread 29, and the driving motor 12 is stopped when the side panel 32 is about to fit the protrusion 30. The hydraulic mechanism 6 is started to adjust the position height of the fixing plate 8 so that the protrusion 30 on one side of the stair tread 29 can be fixed at the height of the engagement groove 31 on the side panel 32. Then the driving motor 12 is started again to drive the slide plate 4 to slide and connect the side panel 32 with the stair tread 29 to complete the splicing of the stairs. After the splicing is completed, the stairs can be removed.

[0037] As a further solution of the present invention, the swing transmission mechanism includes a first positioning plate 17, one end of the first rotating shaft 15 is rotatably connected to the first positioning plate 17, one end of the first positioning plate 17 is rotatably connected to the third rotating shaft 27, the first rotating shaft 15 and the third rotating shaft 27 are commonly connected to the first transmission belt 16, the first positioning plate 17 is externally sleeved with a fixed frame 18, one end of the third rotating shaft 27 is fixedly connected to a connecting shaft 28, the connecting shaft 28 is rotatably connected to the inner wall of the fixed frame 18, one end of the third rotating shaft 27 is fixedly connected to a third gear 24, and one end of the third gear 24 is meshed with a fourth gear 25. The fourth gear 25 is fixedly connected to a second rotating shaft 26 that is rotatably connected to the inner wall of the fixed frame 18. One end of the second rotating shaft 26 is rotatably connected to the second positioning plate 20. One end of the second positioning plate 20 is rotatably connected to a fourth rotating shaft 33. The fourth rotating shaft 33 is rotatably arranged on the side wall of the rotating plate 11. The second rotating shaft 26 and the fourth rotating shaft 33 are commonly connected to the second transmission belt 19. One end of the fourth rotating shaft 33 is fixedly connected to the first gear 22. One end of the first gear 22 is meshed with the second gear 23. A connecting frame 21 is fixedly connected to the side wall of the sliding plate 2. One end of the second gear 23 is rotatably connected to the connecting frame 21.

[0038] When the above scheme is put into actual use, after the spacing adjustment of the sliding plate 2 is completed, the fixed motor 14 is started to drive the first rotating shaft 15 to rotate. The first rotating shaft 15 first drives the support plate 1 to rotate, and drives the third gear 24 to rotate through the first transmission belt 16. The third gear 24 drives the fourth gear 25 to rotate. The fourth gear 25 drives the first gear 22 to rotate through the transmission of the fourth rotating shaft 33. The first gear 22 drives the support plate 1 fixed thereto to rotate, and the rotation direction is opposite to the direction of the support plate 1 rotated by the first rotating shaft 15. The first gear 22 then passes through the second gear 23 through another group of third gears 24, fourth gear 25 and other series of transmissions to drive the next group of support plates 1 to rotate, and the rotation angle interval is the same. The installation of the stairs is as follows Figure 6As shown, the stair treads 29 need to be cross-fixed at two groups of angles. The swing transmission mechanism can just realize equal-angle rotation of the support plate 1 while controlling the rotation angle order of the support plate 1 to be opposite. Moreover, when the spacing of the sliding plates 2 is adjusted through the limit frame 10, the change in the spacing between adjacent sliding plates 2 will change the angle of the first positioning plate 17 and the second positioning plate 20, and will also change the inclination angle between each group of support plates 1, and the rotation direction of each adjacent support plate 1 is still opposite. The purpose of this is that after the inclination angle of the sliding plate 2 is adjusted, the support plate 1 at its top will deflect accordingly, and then the inclination angle of the support plate 1 can be further adjusted through the first rotating shaft 15 to meet the angle requirements during splicing, so that the adjustment of the spacing between the sliding plates 2 will not affect the adjustment of the angle of the support plate 1. The angles of all support plates 1 can be adjusted at one time, which can greatly improve the efficiency of stair splicing.

[0039] As a further solution of the present invention, the bottom end of the slide plate 4 is rotatably connected to a sliding wheel, one end of the fixing frame 3 is fixedly connected to a driven shaft, and the slide plate 4 is slidably sleeved on the driven shaft;

[0040] When the above solution is put into actual use, the sliding friction of the slide plate 4 is replaced by rolling friction through the sliding wheel, which reduces the friction and increases the service life of the slide plate 4. The driven shaft together with the screw rod 5 drives the slide plate 4 to slide, making the slide plate 4 more stable when sliding.

[0041] As a further solution of the present invention, the outer wall of the fixing frame 3 is a smooth wall, and the inner wall of the sliding plate 2 can be completely fitted with the fixing frame 3;

[0042] When the above solution is put into practical use, the smooth fixing frame 3 has less frictional resistance on the sliding plate 2 when sliding, making the sliding plate 2 more convenient to slide.

[0043] As a further solution of the present invention, one end of the sliding plate 2 is fixedly connected to a fixed motor 14, and the output end of the fixed motor 14 is fixedly connected to the first rotating shaft 15;

[0044] When the above solution is put into practical use, the fixed motor 14 drives the first rotating shaft 15 to rotate, thereby driving the multiple groups of support plates 1 to rotate together. The rotation direction of the support plates 1 can be controlled by controlling the forward and reverse rotation of the fixed motor 14.

[0045] As a further solution of the present invention, a baffle is fixedly connected to one side of the top of the fixed plate 8, and an anti-slip pad with a high friction coefficient is fixedly connected to the side wall of the baffle;

[0046] When the above solution is put into actual use, the friction of the baffle surface is increased by the anti-slip pad, in order to stabilize the side panel 32, and at the same time, the pressure between the side panel 32 and the inner wall of the fixed plate 8 is reduced by the soft pad to avoid wear of the side panel 32.

[0047] Working principle: Place the processed stair tread 29 on the support plate 1 above the sliding plate 2, determine the spacing between each stair tread 29 according to the size of the stairs, and drive the transmission frame 9 to extend and retract as a whole by pressing down or pulling up the limit frame 10, and control the sliding plate 2 to slide and adjust the spacing on the fixed frame 3 through the roller 13. The limit frame 10 can keep each sliding plate 2 sliding at an equal distance during the sliding process, so as to ensure that the spacing of each stair tread 29 is the same after adjustment. When the spacing adjustment of the sliding plate 2 is completed, start the fixed motor 14 to drive the first rotating shaft 15 to rotate, and the first rotating shaft 1 First, the support plate 1 is driven back to rotate, and then the third gear 24 is driven to rotate by the first transmission belt 16. The third gear 24 drives the fourth gear 25 to rotate. The fourth gear 25 drives the first gear 22 to rotate through the fourth rotating shaft 33. The first gear 22 drives the support plate 1 fixed thereto to rotate, and the rotation direction is opposite to the direction of the support plate 1 rotated by the first rotating shaft 15. The first gear 22 then drives another set of third gears 24, fourth gears 25, and so on through the second gear 23, and drives the next set of support plates 1 to rotate. The rotation angle interval is the same. The installation of the stairs is as follows Figure 6 As shown, the stair treads 29 need to be cross-fixed at two groups of angles. The swing transmission mechanism can just realize equal-angle rotation of the support plate 1 while controlling the rotation angle sequence of the support plate 1 to be opposite. Moreover, when the sliding plate 2 is adjusted to a distance through the limit frame 10, the change in the distance between adjacent sliding plates 2 will change the angle of the first positioning plate 17 and the second positioning plate 20, and will also change the inclination angle between each group of support plates 1. The rotation directions of each adjacent support plate 1 are still opposite. After the position angle adjustment of the stair tread 29 is completed, the side plates 32 on both sides are placed on the two fixed plates respectively. 8, note that the slot 31 is facing the end of the protrusion 30, and is fixed from both ends of the side panels 32 through the clamping frames 7 on both sides, and the drive motor 12 is started to drive the screw rod 5 to rotate, pushing the slide plate 4 to slide toward the stair board 29, and the drive motor 12 is stopped when the side panel 32 is about to fit with the protrusion 30, and the hydraulic mechanism 6 is started to adjust the position height of the fixed plate 8 so that the protrusion 30 on one side of the stair board 29 can be fixed at the height of the slot 31 on the side panel 32, and then the drive motor 12 is started to drive the slide plate 4 to slide and connect the side panel 32 with the stair board 29 to complete the splicing of the stairs.
