[0013] Compared with the prior art, the beneficial effect of the utility model is that when the construction ladder with a bottom anti-skid structure is in use, the support block can be placed stably on the ground according to needs, and then the support frame can be rotated to a suitable angle through the rotating shaft. At this time, the rotating rod is rotated, and the rotating rod will drive the two-way screw to rotate through the bevel gear set, and with the cooperation of the screw sleeve and the top rod, the card block limits the transmission gear. At this time, the transmission gear cannot rotate, so that the support frame can be more stably fixed on the support block, and the support block and the anti-slip block can achieve a good anti-skid effect to avoid sliding of the bottom of the ladder. This is the use feature of the construction ladder with a bottom anti-skid structure.

[0014] 1. The construction ladder with a bottom anti-slip structure is needed to facilitate construction at high places during construction. In order to prevent the bottom of the ladder from sliding and affecting the stability of the ladder, the support block can be placed on a stable ground, and then the angle of the support frame can be adjusted, and the support frame can be fixed by the cooperation of the clamping block and the transmission gear.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1 and Figure 2 The utility model provides a technical solution: a construction ladder with a bottom anti-slip structure, comprising: a support frame 1 and a fixing rod 3, a horizontal plate 2 is connected between two groups of support frames 1 through a rotating shaft, and the fixing rod 3 is installed on the top of the support frame 1;

[0024] A transmission gear 4 is installed at the bottom of the support frame 1 through a groove, and a rotating shaft 5 that passes through the support frame 1 is connected in the middle of the transmission gear 4, support blocks 6 are installed at both ends of the rotating shaft 5, and an anti-sliding block 7 is installed at the bottom of the support block 6. A connecting rod 8 is installed between the two groups of support blocks 6, and a rotating rod 9 is connected to the top of the connecting rod 8. The bottom of the rotating rod 9 is connected to a bidirectional screw rod 10 through a bevel gear set, and screw sleeves 11 are sleeved on both ends of the bidirectional screw rod 10. A push rod 12 is installed on one side of the screw sleeve 11, and a block 13 that passes through the connecting rod 8 is installed on the top of the push rod 12.

[0025] During specific implementation, the construction ladder with a bottom anti-slip structure can be used to place the support block 6 stably on the ground, and then the support block 6 is grounded according to the placement of the ladder. The entire support frame 1 is rotated through the rotating shaft 5 between the support block 6 and the support frame 1, so that the fixed rod 3 at the top of the support frame 1 is against the wall, and then the rotating rod 9 is rotated. A bevel gear set is installed at the bottom of the rotating rod 9. The bevel gear set is connected by two mutually meshing bevel gears, one of which is connected to the rotating rod 9, and the other is connected to the bidirectional screw rod 10. When the rotating rod 9 rotates, the bidirectional screw rod 10 will be driven to rotate through the bevel gear set. Both ends are connected with screw sleeves 11. At this time, the two screw sleeves 11 will move away from each other and drive the block 13 to move through the top rod 12 on one side, so that the block 13 moves in the direction of the transmission gear 4, so that the block 13 limits the transmission gear 4. At this time, the transmission gear 4 cannot rotate, so that the support frame 1 cannot rotate through the rotating shaft 5. The entire support frame 1 is stably placed on the ground through the support block 6 at the bottom, and an anti-slip block 7 is installed at the bottom of the support block 6. The anti-slip block 7 can increase the contact area between the ladder and the ground, so that the anti-slip effect of the entire ladder can be better, and sliding at the bottom of the ladder can be avoided.

[0026] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 It can be seen that when in use, the entire support block 6 can be placed on a stable ground, and the transmission gear 4 can be limited by the clamping block 13, so that the support frame 1 cannot rotate, and the universal anti-sliding block 7 ensures the stability of the entire support frame 1.

[0027] Movable springs 14 are installed on both sides of the cross plate 2 through grooves, one side of the movable spring 14 is connected to a movable block 15 that passes through the cross plate 2, the top of the movable block 15 is installed with a pulling block 16 that passes through the cross plate 2, a fixed block 17 is installed on the side of the support frame 1 close to the cross plate 2, and a limiting block 18 is installed on the top of the cross plate 2.

[0028] When the construction ladder with a bottom anti-slip structure is in use, the pull block 16 can be pulled so that the pull block 16 drives the movable block 15 on one side to retract into the groove of the horizontal plate 2 and squeezes the movable spring 14 in the groove of the horizontal plate 2. At the same time, the movable block 15 will move out of the groove of the support frame 1. Without the movable block 15 limiting the horizontal plate 2, the horizontal plate 2 can be rotated by the rotating shaft so that the horizontal plate 2 changes from the vertical direction to the horizontal direction, and the horizontal plate 2 is connected to the top of the fixed block 17 through the groove at the bottom. The fixed block 17 can play a role in stabilizing the support of the horizontal plate 2, and at the same time, the pull block 16 is released so that the movable block 15 can be moved out of the groove of the support frame 1. The block 15 is reset by the movable spring 14, and the movable block 15 is inserted into the groove of the support frame 1, so that the cross board 2 can be fixed. By increasing the overall width of the cross board 2, the user can be more stable when climbing up through the cross board 2. Conversely, the movable block 15 can be pulled into the groove of the cross board 2 again, and then the cross board 2 is rotated by the shaft. Under the action of the limit block 18, the cross board 2 can only be rotated 90°, thereby becoming a vertical state, and then the movable block 15 is reset by the movable spring 14. At this time, the cross board 2 can be fixed. When carrying, you only need to lift the position of the cross board 2, so that it is convenient to carry the ladder.

[0029] See also Figure 1 , Figure 2 and Figure 3 It can be seen that when in use, the horizontal board 2 can be rotated according to needs, so as to increase the overall width of the horizontal board 2, making the user more stable when climbing.

[0030] To sum up: when using the construction ladder with a bottom anti-slip structure, the entire support block 6 can be placed on a flat ground according to usage requirements, and then the entire support frame 1 can be rotated through the shaft according to construction requirements, so that the fixed rod 3 on the top of the support frame 1 is against the wall. At this time, the construction workers can climb up along the ladder through the cross plate 2 between the two groups of support frames 1, thereby facilitating the construction workers to carry out construction. This is the use feature of the construction ladder with a bottom anti-slip structure. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
