[0025] Among them, the connecting component 200 is installed in the supporting block 130 on the pedal 100. Through the connecting component 200, the supporting blocks 130 on the first ladder body 110 and the second ladder body 120 can be connected so that the supporting blocks 130 are in contact with the ground, thereby reducing the poor stability of the stepladder and the possibility of workers shaking easily when standing on the pedal 100.

[0026] See also Figure 1-Figure 2 The first ladder body 110 and the second ladder body 120 are rotatably mounted on the lower surface of the pedal 100 , and two supporting blocks 130 are rotatably mounted on the surfaces of the first ladder body 110 and the second ladder body 120 .

[0027] In this embodiment, a step rod 111 is provided in both the first ladder body 110 and the second ladder body 120. There are a plurality of step rods 111, and an anti-slip cover 112 is provided on the surface of the step rod 111. In a specific implementation, by providing a plurality of step rods 111 in the first ladder body 110 and the second ladder body 120, and installing the anti-slip cover 112 on the step rod 111, the possibility of a worker falling from the step ladder when climbing the step ladder is reduced. It should be noted that the anti-slip cover 112 can be made of rubber or silicone.

[0028] See also Figure 1-Figure 2 The connecting assembly 200 includes two transmission members 210 and two rotating members 220, which are respectively rotatably installed in the corresponding support blocks 130, and the transmission members 210 and the rotating members 220 are in transmission connection, and the surfaces of the two rotating members 220 are both threadedly sleeved with moving seats 230, and the moving seats 230 are slidably arranged in the support block 130, wherein a stud 240 is connected to the surface of one moving seat 230, and an internal thread sleeve 250 is rotatably connected to the side of the other moving seat 230, and the stud 240 is threadedly connected to the internal thread sleeve 250. In a specific implementation, by rotating the first ladder body 110 and the second ladder body 120 by a certain angle, and then rotating the support blocks 110 and 110 on the surfaces of the two ladder bodies, 30, the support block 130 is in contact with the ground, and the transmission member 210 is rotated to drive the rotating member 220 to rotate, so that the movable seat 230 can move along the inside of the support block 130, which is beneficial to the stability of the movable seat 230 during the movement. When the stud 240 and the internal threaded sleeve 250 are in contact, the internal threaded sleeve 250 can be rotated during the movement of the movable seat 230. The internal threaded sleeve 250 can be connected to the stud 240, which is beneficial to the stability of the connection between the support block 130 on the first ladder body 110 and the support block 130 on the second ladder body 120. By having multiple support blocks 130 in contact with the ground, the poor stability of the ladder and the possibility of the staff standing on the pedal 100 shaking are reduced.

[0029] In this embodiment, the transmission member 210 includes a connecting rod 211, a first bevel gear 212 and a handwheel 213. The connecting rod 211 is rotatably installed in the support block 130, and the connecting rod 211 is respectively connected to the first bevel gear 212 and the handwheel 213, and the first bevel gear 212 is transmission-connected to the rotating member 220; the rotating member 220 includes a rotating rod 221, a second bevel gear 222 and a screw rod 223. The rotating rod 221 is rotatably installed in the support block 130, and the rotating rod 221 is respectively connected to the second bevel gear 222 and the screw rod 223, the second bevel gear 222 is meshingly connected to the first bevel gear 212, and the movable seat 230 is threadedly sleeved on the surface of the screw rod 223.

[0030] A cavity 131 is provided in the support block 130, and the first bevel gear 212 and the second bevel gear 222 are both located in the cavity 131. In a specific implementation, the first bevel gear 212 and the second bevel gear 222 are arranged in the cavity 131, which is beneficial to protecting the first bevel gear 212 and the second bevel gear 222; a placement groove 132 is provided in the support block 130, and the movable seat 230 is fitted with the inner wall of the placement groove 132. In a specific implementation, when the screw rod 223 rotates, the movable seat 230 can be moved along the inner wall of the placement groove 132, and the moving trajectory of the angle screw rod 223 may be offset during the movement.

[0031] The surface of the moving seat 230 is connected to the limiting block 231, and the supporting block 130 is provided with a limiting groove 133. The limiting block 231 is slidably arranged in the limiting groove 133. In the specific implementation, when the screw rod 223 drives the moving seat 230 to move, the limiting block 231 on the surface of the moving seat 230 will move along the inner wall of the limiting groove 133, thereby reducing the possibility that the moving seat 230 will fall off from the placement groove 132 due to excessive movement distance; the surfaces of the first ladder body 110 and the second ladder body 120 are both installed with a fixing block 140, and the fixing block 1 A limiting hole 141 is provided on the surface of the fixing block 140, and the diameter of the limiting hole 141 is not less than the diameter of the internal threaded sleeve 250. In a specific implementation, when the stepladder is no longer in use, the support block 130 is rotated to make the support block 130 flush with the side of the first ladder body 110 or the second ladder body 120. By rotating the hand wheel 213, the movable seat 230 can be driven to move, so that the stud 240 or the internal threaded sleeve 250 enters the limiting hole 141 on the surface of the fixing block 140, thereby reducing the possibility that the support block 130 will automatically rotate when the stepladder is not in use.

[0032] Specifically, the working principle of the herringbone ladder for indoor decoration is as follows: when in use, the first ladder body 110 and the second ladder body 120 are rotated to a certain angle, and then the support block 130 is rotated to a certain angle, so that the support block 130 is in contact with the ground, and the hand wheel 213 is rotated to drive the connecting rod 211 and the first bevel gear 212 to rotate, and then the second bevel gear 222, the rotating rod 221 and the screw rod 223 are rotated, so that the moving seat 230 can move along the inner wall of the placement groove 132, and the moving track of the moving seat 230 will be deviated during the movement process. The movable seat 230 can drive the stud 240 and the internal threaded sleeve 250 to move, so that the stud 240 contacts the internal threaded sleeve 250. By rotating the internal threaded sleeve 250, the internal threaded sleeve 250 can be connected to the stud 240 during the movement of the movable seat 230, which is beneficial to the stability of the connection between the support block 130 on the first ladder body 110 and the support block 130 on the second ladder body 120. By contacting the ground with multiple support blocks 130, the poor stability of the ladder and the possibility of shaking when the staff stands on the pedal 100 are reduced.
