Technical Field

[0001] The present application relates to the technical field of ladders, and more specifically, to a safety ladder for buildings. Background Art

[0002] Currently on construction sites, building ladders allow people to climb to higher points to perform work, and building ladders occupy an important position on construction sites.

[0003] The document with the prior art publication number CN220118061U3 provides a multifunctional ladder for industrial construction, which carries the painting materials or tools required by workers through a carrier box, and drives the rotating part to drive the threaded rod fixed to it to rotate along the support plate, and the rotation of the threaded rod will link the moving seat to move along the ladder frame, and then the moving seat drives the carrier box 7 to move to the required use position, which effectively avoids the need for workers to carry painting materials or tools to climb the ladder with their hands in the existing device, resulting in low safety for workers to carry things in one hand and climb the ladder with the other hand, which is beneficial to the device for moving and transporting the painting materials or tools to be carried, and increases the safety of the device.

[0004] Although the device has many beneficial effects, the following problems still exist: when the steps are damaged or broken, it is difficult to replace them quickly, and the ladder can only be replaced as a whole, which easily increases the maintenance cost of the ladder. In view of this, we propose a building safety ladder. Utility Model Content

[0005] The embodiment of the present application provides a safe building ladder, which solves the technical problem in the prior art that when the steps are damaged or broken, it is difficult to quickly replace them and the only way to replace the ladder as a whole is to easily increase the maintenance cost of the ladder.

[0009] By adopting the above technical solution and setting a positioning mechanism, when the connecting rod on the inner side of the mounting plate is damaged, the staff can quickly remove and replace the damaged connecting rod without replacing the entire ladder, thereby reducing the maintenance cost of the ladder.

[0010] Optionally, a spring is fixedly connected to one side of the fixed plate, and one end of the spring is fixedly connected to the other side of the displacement plate, so that the displacement plate will not move arbitrarily in a direction close to the fixed plate.

[0011] By adopting the above technical solution and setting a spring, when the displacement plate moves toward the fixed plate, the spring will be gradually squeezed, so that the movement resistance of the displacement plate is gradually increased, thereby preventing the plug-in board from moving out of the slot at will.

[0025] The present application is further described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a building safety ladder. The building safety ladder comprises: two mounting plates 1;

[0027] A plurality of connecting rods 2 are arranged between the two mounting plates 1, and a plurality of positioning mechanisms 3 are arranged on one side of the mounting plate 1 for positioning the connecting rods 2;

[0028] The positioning mechanism 3 includes a rotating rod 32, which is rotatably connected to one side of the mounting plate 1. A baffle 33 is provided on the outer fixed sleeve of the rotating rod 32. A groove is provided on one side of the mounting plate 1. Both ends of the connecting rod 2 are fixedly connected with connecting blocks 31. The connecting block 31 is located in the groove, and the baffle 33 fits with the connecting block 31. A fixing ring 34 is provided on the outer fixed sleeve of the rotating rod 32. Four slots are provided on the outer side of the fixing ring 34. A fixing plate 37 is fixedly connected to one side of the mounting plate 1. A displacement plate 35 is elastically connected to one side of the fixing plate 37. A plug-in plate 36 located in the slot is fixedly connected to one side of the displacement plate 35, so that the staff can quickly replace the damaged connecting rod 2 and reduce the maintenance cost.

[0029] Reference Figure 1 and Figure 3 The angle between two adjacent slots is ninety degrees, so that the baffle 33 can release the positioning of the connecting block 31 after rotating ninety degrees.

[0030] Reference Figure 1 and Figure 3 A spring 39 is fixedly connected to one side of the fixed plate 37 , and one end of the spring 39 is fixedly connected to the other side of the displacement plate 35 , so that the displacement plate 35 will not move in a direction close to the fixed plate 37 at will.

[0031] Reference Figure 1 and Figure 3 A hole is formed through one side of the fixed plate 37, a slide rod 38 is slidably connected in the hole, and one end of the slide rod 38 is fixedly connected to the pull plate 4, so as to facilitate pulling the displacement plate 35 to move toward the direction close to the fixed plate 37.

[0032] Reference Figure 1 and Figure 3 The sizes of the pull plate 4 and the displacement plate 35 are both larger than the size of the inner side of the opening, thereby preventing the slide bar 38 from escaping from the opening.

[0033] Reference Figure 1 and Figure 3 Guide grooves are provided on both sides of the inner wall of the opening, and guide strips 5 are fixedly connected to both sides of the slide bar 38, and the guide strips 5 are slidably connected in the guide grooves, thereby preventing the slide bar 38 from rotating in the opening.

[0034] Reference Figure 1 A base 6 is provided under the mounting plate 1, and mounting frames 7 are fixedly connected to both sides of the top of the base 6. A rotating shaft 8 is rotatably connected to the inner side of the mounting frame 7. The mounting plate 1 is fixedly sleeved on the outer side of the rotating shaft 8 to increase the contact area with the ground and improve the safety performance of the ladder when in use.

[0035] Reference Figure 1 A pad 9 is fixedly connected to the bottom of the base 6, and the pad 9 is made of rubber material, so as to ensure the anti-slip performance of the base 6.

[0036] Reference Figure 1 Two through holes are formed on both sides of the base 6 and the top of the pad 9, which makes it easy to fix the base 6 on the ground by external bolts or ground nails.

[0037] The implementation principle of a building safety ladder in the embodiment of the present application is as follows: when the connecting rod 2 is damaged, the staff can pull the pull plate 4, thereby driving the displacement plate 35 to move and squeeze the spring 39 through the sliding rod 38. The movement of the displacement plate 35 can drive the plug plate 36 to move, so that the plug plate 36 moves out of a certain slot, and then the rotating rod 32 is rotated to drive the baffle plate 33 and the fixing ring 34 to rotate, so that the baffle plate 33 rotates ninety degrees and separates from the connecting block 31. At this time, the connecting block 31 can be taken out of the groove, so that the connecting rod 2 is removed, and then the new connecting rod 2 is placed between the two mounting plates 1, and the new connecting block 31 is placed in the groove, and then the rotating rod 32 is rotated ninety degrees in the opposite direction, so that the baffle plate 33 fits with the connecting block 31, and then the pull plate 4 is released, so that the squeezed spring 39 rebounds and drives the displacement plate 35 and the plug plate 36 to move in the direction close to the fixing ring 34 until the plug plate 36 is inserted into another slot, so that the connecting rod 2 can be quickly replaced.

[0038] The embodiment of the present application provides a safety ladder for buildings. By setting a positioning mechanism 3, when the connecting rod 2 on the inner side of the mounting plate 1 is damaged, it is convenient for workers to quickly remove and replace the damaged connecting rod 2 without replacing the entire ladder, thereby reducing the maintenance cost of the ladder.
