DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-2 As shown, the utility model provides an anti-skid sand belt for herringbone ladder pedals, comprising: a herringbone ladder body 1 with multiple step areas, each step area is provided with an anti-skid sand belt body 3 and a step body from top to bottom, and a mounting groove 4 for accommodating the anti-skid sand belt body 3 is formed on the top of the step body, and the top end of the anti-skid sand belt body 3 extends to the top of the mounting groove 4.

[0025] As described above, when using the herringbone ladder body 1, the pedal body 2 and the anti-skid belt body 3 provided by the utility model, the anti-skid belt body 3 is embedded and installed on the top of the pedal body 2 through the installation groove 4, and the anti-skid belt body 3 provides an anti-skid component for the pedal body 2, and the anti-skid belt body 3 makes the pedal body 2 have an anti-skid effect, increases friction, and enhances safety performance. It plays an anti-skid role, and the anti-skid belt body 3 is integrally formed with Peva.

[0026] In the present utility model, combined with Figure 2-3 As shown, an adjustment mechanism for adjusting the height of the anti-slip belt body 3 is also installed in the installation groove 4 of this embodiment, and the anti-slip belt body 3 is arranged on the top of the adjustment mechanism.

[0027] Combination Figure 3 As shown, the adjustment mechanism includes a mounting plate 9 and a screw 14. The screw 14 is longitudinally rotatably installed in the mounting groove 4. A threaded hole 15 for accommodating the screw 14 is opened at the bottom of the mounting plate 9. A driving member for driving the screw 14 to rotate is installed at the bottom of the pedal body 2. The anti-slip belt body 3 is detachably installed on the top of the mounting plate 9.

[0028] As mentioned above, when using the adjustment mechanism provided by the utility model, the mounting plate 9 in the adjustment mechanism provides an installation position for the anti-slip belt body 3 in the mounting groove 4, and a part of the screw 14 is placed in the mounting plate 9 through the threaded hole 15. The screw 14 can be driven to rotate by the driving member. When the driving member rotates, the screw 14 rotates, and the force of the rotation of the rotating part 11 can be converted into a force for the mounting plate 9 to perform lifting and lowering adjustment in the mounting groove 4 through the threaded hole 15, thereby facilitating the anti-slip belt body 3 in the mounting groove 4 to be pushed outward from the mounting groove 4. When the anti-slip belt body 3 that leaks out of the mounting groove 4 is worn, the anti-slip belt body 3 in the mounting groove 4 is pushed outward by the driving member, so that the anti-slip belt body 3 can be used multiple times.

[0029] Further, in order to facilitate the rotational drive of the screw 14, refer to Figure 3 As shown, the driving member includes a rotating part 11, a groove 10 is provided at the bottom of the pedal body 2, the rotating part 11 is rotatably installed in the groove 10, and the rotating part 11 is arranged at one end of a screw rod 14. The groove 10 facilitates the rotating part 11 to be embedded and rotatably installed at the bottom of the pedal body 2. When the rotating part 11 is rotated, the screw rod 14 can be driven to rotate, thereby driving the mounting plate 9 to be raised and lowered in the mounting groove 4.

[0030] Further, in order to allow the rotating portion 11 to be rotatably installed in the mounting groove 4, refer to Figure 3 As shown, a rotating groove 12 is provided between the installation groove 4 and the groove 10, and a rotating block 13 is provided on the screw 14 and can rotate in the rotating groove 12. The rotating portion 11 can be rotatably installed in the groove 10 through the rotating groove 12 and the rotating block 13.

[0031] In the present utility model, combined with Figure 3 As shown, the bottom of the anti-slip sand belt body 3 of this embodiment is symmetrically provided with two plug-in posts 6 , and the top of the mounting plate 9 is symmetrically provided with two plug-in holes 5 , one end of the two plug-in posts 6 is respectively plugged into the two plug-in holes 5 .

[0032] As mentioned above, when using the plug-in posts 6 provided by the utility model, after the two plug-in posts 6 on the anti-slip belt body 3 are plugged into the corresponding plug-in holes 5, the anti-slip belt body 3 can be detachably mounted on the mounting plate 9, and the plug-in posts 6 are used to prevent the anti-slip belt body 3 from being displaced on the mounting plate 9.

[0033] Further, in order to facilitate the detachable installation of the plug-in column 6 in the plug-in hole 5, refer to Figure 3 As shown, a ball block 8 is installed at the bottom of each plug-in column 6, and a ball groove 7 for accommodating the corresponding ball block 8 is opened in each plug-in hole 5. The diameter of the ball block 8 is larger than the inner diameter of the plug-in hole 5. When the plug-in column 6 is plugged into the plug-in hole 5, the ball block 8 is engaged in the ball groove 7. In the absence of external force, the plug-in column 6 cannot be separated from the plug-in hole 5. When the plug-in column 6 is separated from the plug-in hole 5, the anti-slip belt body 3 can be replaced.
