Detailed implementation

[0066] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0067] Such as Figures 1 to 10 shown, an adjustable auxiliary scaffold for interior decoration includes a support pedal 1 and support legs 201 rotatably connected to the four corners of the bottom surface of the support pedal 1, and further includes an adjustable armrest assembly, and the armrest assembly includes:

[0068] Two moving seats 2, and the two moving seats 2 are respectively slidably connected to both sides of the support pedal 1;

[0069] Two armrests 3, the armrests 3 are rotatably connected to the moving seats 2, and a handle 4 is detachably connected between the tops of the two armrests 3;

[0070] Auxiliary support assembly, the auxiliary support assembly includes an auxiliary support frame 5 rotatably connected to the armrest frame 3. When the armrest frame 3 is flipped to the vertical state to be held, a triangular frame structure is formed among the auxiliary support frame 5, the armrest frame 3 and the moving seat 2;

[0071] Locking assembly, the locking assembly is used to synchronously lock the states of the auxiliary support frame 5 and the armrest frame 3 to maintain the stability of the triangular frame mechanism.

[0072] It should be understood that during the use of the scaffolding, it is necessary to first flip and unfold the four support legs from the four corners of the support pedal 1 to form a support state, and then flip the armrest frame 3 so that the armrest frame 3 is flipped to the vertical state and forms a perpendicular state with the moving seat 2. Then, a handle 4 is detachably connected between the tops of the two armrest frames 3, thereby realizing the setting of a support mechanism on the scaffolding, which not only satisfies the foldable storage in the storage state but also realizes the function of providing support during use, which is beneficial for the staff to work safely under control;

[0073] It should be further noted that when the armrest frame 3 is flipped to a state perpendicular to the moving seat 2, a triangular frame structure is formed between the two ends of the auxiliary support frame 5 of the auxiliary support assembly and the armrest frame 3 and the moving seat 2 respectively. And under the action of the locking assembly, the stability of the armrest frame 3 relative to the moving seat 2 is further enhanced, which is beneficial to providing stable support for the staff;

[0074] It should be further noted that after being locked by the locking assembly, the triangular frame structure formed between the auxiliary support frame 5 and the armrest frame 3 and the moving seat 2 is locked to maintain the stability of the triangular frame mechanism and the stability of the holding state. And when folding and storing are required, the locking of the locking mechanism can be cancelled, which is convenient to use.

[0075] As a further embodiment of the present invention, it further includes:

[0076] Two first chutes 6, the two first chutes 6 are respectively opened on both sides of the support pedal 1 to slidably support the moving seat 2;

[0077] Two extension platforms 7, the two extension platforms 7 are respectively fixedly connected to both sides of the support pedal 1, and connection chutes are opened at the edges;

[0078] Two first support shafts 8, the two first support shafts 8 are respectively movably inserted at the bottom ends of the armrest frames 3. One end of the first support shaft 8 is rotatably connected to the moving seat 2, and the other end is rotatably connected with a first slider 9, and the first slider 9 is slidably connected with the connection chute;

[0079] Two second support shafts 10, the two second support shafts 10 are movably inserted into one end of the auxiliary support frame 5 away from the armrest frame 3 at the corresponding positions, and a third slider 11 and a fourth slider 12 are respectively fixedly connected to both ends. The third slider 11 and the fourth slider 12 are respectively slidably connected to the edge of the moving seat 2 and the connecting chute;

[0080] When the armrest frame 3 is flipped to the vertical state to be held, the locking component locks the position of the fourth slider 12, so as to lock the vertical state of the armrest frame 3 relative to the moving seat 2.

[0081] It should be understood that after the fourth slider 12 is locked, the position of the fourth slider 12 on the moving seat 2 will be positioned, and then the two ends of the auxiliary support frame 5 will be positioned, and then a stable triangular frame mechanism will be formed among the armrest frame 3, the moving seat 2 and the auxiliary support frame 5, which is beneficial to maintaining the stability of the vertical state of the armrest frame 3 relative to the moving seat 2, and further provides stable support for the handle 4;

[0082] It should be further noted that when storage is required, the locking of the fourth slider 12 is cancelled by the locking component, and the armrest frame 3 is flipped so that the armrest frame 3 is flipped and folded against the moving seat 2, and the auxiliary support frame 5 will also be folded synchronously. During the folding process, the fourth slider 12 and the third slider 11 will slide in the connecting chute and along the edge of the moving seat 2 respectively, providing the degrees of freedom required for folding. And after folding, the armrest frame 3 can be pushed into the first chute 6. During the process of pushing the armrest frame 3 and the auxiliary support frame 5 into the first chute 6, the first support shaft 8 and the second support shaft 10 always maintain the support for the armrest frame 3 and the auxiliary support frame 5.

[0083] By providing a foldable and storable armrest frame 3, a supportable point is set for the support pedal 1. During storage, through the folding and storage of the armrest frame 3, it remains regular, which is beneficial to reducing the difficulty of later storage. And moving the armrest frame 3 into the edge of the support pedal 1 is beneficial to further reducing the space occupation.

[0084] As an optional implementation manner of the present invention, the locking component includes:

[0085] A rotating disk 13, the rotating disk 13 is rotatably connected to the top of the third slider 11 and fixedly connected to the end of the first support shaft 8. The surface of the rotating disk 13 is provided with a first clamping groove 1301, a second clamping groove 1302 and a third clamping groove 1303;

[0086] The armrest frame 3 is slidably connected to the surface of the first support shaft 8 along the axial extension direction of the first support shaft 8 to achieve the synchronism of rotation along the axis of the first support shaft 8;

[0087] A clamping pin 14, the clamping pin 14 is slidably arranged on the side wall of the armrest frame 3 to cooperate with the first clamping groove 1301 for clamping;

[0088] The support rail 15 is fixedly connected to the surface of the first slider 9;

[0089] The clamping seat 16 is slidably inserted on the support rail 15 and is supported by an elastic support member between it and the support rail 15;

[0090] The linkage pin 17 has one end fixedly connected to the clamping seat 16 and the other end slidably inserted into the third clamping groove 1303.

[0091] It should be understood that during the process of flipping the armrest frame 3 to reach the vertical moving seat 2, the fourth slider 12 will approach the clamping seat 16 until it reaches the position of the clamping seat 16. Press the clamping seat 16 so that when the fourth slider 12 moves to the top of the clamping seat 16, cancel the pressing. Under the support of the elastic support member, the clamping seat 16 will sleeve the fourth slider 12 to form a limit, and insert the linkage pin 17 into the third clamping groove. On the one hand, it realizes the locking of the tripod mechanism, and on the other hand, it further locates the vertical state of the armrest frame 3.

[0092] It should be further noted that when the armrest frame 3 is pulled out from the first sliding groove 6, the linkage pin 17 is in a state of being inserted and limited with the second clamping groove 1302 at this time. After pulling out the armrest frame 3, the clamping pin 14 is inserted into the first clamping groove 1301, so that the armrest frame 3 and the rotating disk 13 are in a rotation synchronization state.

[0093] It should be further noted that in the storage state, the linkage pin 17 is inserted into the second clamping groove 1302 to realize the limitation of the position of the rotating disk 13, so that during the process of pulling out the armrest frame 3 from the first sliding groove 6, the clamping pin 14 and the first clamping groove 1301 can be aligned.

[0094] As a further embodiment of the present invention, it further includes a positioning component, and the positioning component includes

[0095] Two positioning frames 18 are respectively slidably connected to the surfaces of the two armrest frames 3 and the bottom ends are in frictional contact with the top surface of the extension platform 7;

[0096] Two convex wheels 19 are respectively rotatably connected to the tops of the side walls of the two armrest frames 3;

[0097] Two linkage plates 20 are respectively slidably inserted into the tops of the side walls of the positioning frames 18, and an elastic telescopic rod 21 is fixedly connected between them and the positioning frames 18. The tops of the linkage plates 20 are in contact with the distal ends of the convex wheels 19.

[0098] It should be understood that during use, the staff can operate the handle 4 to drive the handrail frame 3 to move, and synchronously drive the moving seat 2 to move, thereby adjusting the position of the handle 4, and adjusting the position of the handle 4 according to the movement of the staff on the support pedal 1, which is convenient for the staff to flexibly adjust according to the actual position to be supported, and is convenient for use;

[0099] It should be further explained that when the handle 4 is moved to the ideal position, the cam wheel 19 is rotated, the cam linkage plate 20 moves downward, and the linkage plate 20 applies downward pressure to the positioning frame 18 through the elastic telescopic rod 21. The bottom end of the positioning frame 18 is in close contact with the top surface of the extension platform 7 to form a friction resistance, which is beneficial to limit the position of the handle 4, maintain the stability of the position of the handle 4, and provide further stability for the support of the staff.

[0100] As an optional embodiment of the present invention, the two ends of the handle 4 are respectively connected to the top ends of the handrail frames 3 on both sides through a connecting assembly, and the connecting assembly includes:

[0101] The plug-in port 22 is provided on the side wall of the cam wheel 19;

[0102] The plug-in prism 23 is elastically and telescopically connected to the end of the handle 4 , and the plug-in prism 23 is plugged into the plug-in port 22 to achieve a detachable connection between the handle 4 and the armrest 3 .

[0103] It should be noted that, by providing the plug-in interface 22 and the plug-in prism 23, a detachable connection between the handle 4 and the top of the handrail frame 3 is achieved;

[0104] Specifically, a connection groove slidably connected to the plug-in prism 23 is formed at the end of the handle 4, and a return spring 24 is fixedly connected between the plug-in prism 23 and the inner wall of the connection groove, thereby realizing an elastic telescopic connection of the plug-in prism 23 at the end of the handle 4.

[0105] As a further embodiment of the present invention, it also includes:

[0106] A limit pin 25, the limit pin 25 is slidably connected to the top of one of the handrail frames 3;

[0107] The limiting groove 26 is provided on the proximal surface of the cam wheel 19 near the position of the limiting pin 25 to cooperate with the limiting pin 25 to achieve the limiting of the cam wheel 19.

[0108] It should be understood that after the cam wheel 19 cams the linkage plate 20 downward to the ideal position, the cam wheel 19 is positioned by moving the limit pin 25 to connect with the limit groove 26, thereby preventing the handle 4 from rotating under the action of external force when in the supporting state, thereby driving the cam to rotate, which is beneficial to maintaining the stable positioning of the armrest frame 3.

[0109] As an alternative embodiment of the present invention, the elastic support member includes:

[0110] The mounting groove 27 is opened on the top surface of the support rail 15. The clamping seat 16 is slidably inserted into the mounting groove 27, and a first support spring 28 is fixedly connected between the bottom surface and the mounting groove 27.

[0111] It should be understood that by providing the first support spring 28, elastic support for the clamping seat 16 is achieved.

[0112] As an alternative technical solution of the present invention, the clamping seat 16 includes:

[0113] The cross-shaped sliding seat 1601 is slidably inserted into the mounting groove 27, and the side end is fixedly connected to the linkage pin 17. The cross-shaped sliding seat 1601 is connected to the mounting groove 27 through the first support spring 28;

[0114] The clamping groove block 1602 is fixedly connected to the end of the cross-shaped sliding seat 1601, sleeved on the outer surface of the fourth slider 12, and a guiding inclined surface is provided at one end.

[0115] It should be understood that under the support of the first support spring 28, the height of the clamping groove block 1602 is maintained. During the process of the fourth slider 12 moving past the clamping groove block 1602, the fourth slider 12 will first press the guiding inclined surface to lower the height of the clamping connection, and then when the fourth slider 12 moves to the top of the clamping groove block 1602, it will be pushed by the first support spring 28 to clamp the fourth slider 12, forming positioning for the fourth slider 12;

[0116] It should be further noted that when it is necessary to cancel the positioning of the fourth slider 12, press the cross-shaped sliding seat 1601 to drive the clamping groove seat to disengage from the fourth slider 12. And during the process of pressing the clamping groove seat, the linkage pin 17 will synchronously disengage from the third clamping groove 1303, canceling the limit on the rotating disk 13, so that the rotation limit of the supporting frame is canceled.

[0117] As an alternative embodiment of the present invention, a gas spring 29 is fixedly connected to the top of the clamping pin 14, and one end of the gas spring 29 principle clamping pin 14 is fixedly connected to the side wall of the armrest frame 3.

[0118] By setting the gas spring 29, it plays a role in supporting the clamping state of the clamping pin 14, and under the action of an external force, it can provide elastic yielding for the clamping pin 14. For example, during the process of pulling out the support frame from the first sliding groove 6, if the clamping pin 14 is not aligned with the first clamping groove 1301, the clamping pin 14 can be first toggled to move the clamping pin 14 away from the docking position. After pulling out, the support frame is flipped for fine adjustment until the clamping pin 14 is aligned with the first clamping groove 1301. Under the support of the gas spring 29, it will automatically be clamped.

[0119] As a further embodiment of the present invention, it further includes a leg auxiliary support assembly, and the leg auxiliary support assembly includes:

[0120] Two connecting rods 30, one end of the two connecting rods 30 is rotatably connected to the bottom end of the side wall of the support leg 201;

[0121] A linkage slider 31, the linkage slider 31 is slidably connected to the side wall of the support leg 201, and the side wall is rotatably connected to the other end of the two connecting rods 30;

[0122] A limit slider 32, the limit slider 32 is slidably arranged in the first sliding groove 6, and the limit slider 32 contacts the end of the extension platform 7;

[0123] A first insertion pin 33, the first insertion pin 33 is fixedly connected to the side wall of the linkage slider 31;

[0124] A second insertion pin 34, the second insertion pin 34 is fixedly connected to the side wall of the limit slider 32, and a support plate 35 is slidably inserted between the second insertion pin 34 and the first insertion pin 33.

[0125] It should be understood that the support points of the support leg 201 are limited, and the support pedal 1 is prone to tipping over to both sides. By setting the two connecting rods 30, the bottom side direction of the support leg 201 is further supported, which is beneficial to improving the support for both sides of the support pedal 1 and is beneficial to maintaining the stability of the entire support state of the support pedal 1;
