Description

Technical Field

[0001] This utility model relates to the field of decoration technology, specifically a triangular ladder for building materials decoration. Background Technology

[0002] Triangular ladders used in building materials decoration and renovation are typically designed as lightweight, portable, and easy-to-operate tools for indoor and outdoor maintenance and decoration work. These ladders usually have three supporting legs arranged in a triangle to provide stability, enabling workers to reach decorative objects such as walls, ceilings, and light fixtures at height.

[0003] When using existing triangular ladders for building materials and decoration, it is necessary to first determine the placement location of the triangular ladder, then stretch the two ends of the triangular ladder to form a stable triangle, and then fix the two ends of the triangular ladder before placing it on the ground. After confirming that it can remain stable, it can be used, and decoration items can be placed on the shelf.

[0004] Existing triangular ladders used in building materials and decoration, although fixed in a triangular shape, are unstable for users due to insufficient foot contact area and the ladder's swaying. This requires constant attention to maintain balance, reducing work efficiency. Furthermore, the lack of a shelf at one end makes it vulnerable to damage during transport and takes up valuable space, making it inconvenient to store or store. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5This utility model provides a triangular ladder for building materials decoration, including a stable support 1. The stable support 1 has two sets, allowing climbing from both sides. A hinge support 8 is fixedly connected to the outer wall of the side end of the stable support 1. The upper end of the hinge support 8 has a square groove for engaging a locking block 11. A limit sleeve 3 is hinged to the outer wall of the hinge support 8. The limit sleeve 3 is fixedly connected to the rotation shaft of the hinge support 8. A limit rod 4 is slidably connected to the inner wall of the limit sleeve 3. The limit rod 4 rotates with the limit sleeve 3, and the height of the handrail 5 can be changed by changing the length of the limit rod 4 inside the limit sleeve 3 to meet the user's needs. A limiting handle 12 is elastically connected via a limiting spring. Multiple E-grooves are formed through the outer wall of the limiting sleeve 3. When the limiting handle 12 is not under tension, it engages within the E-grooves. When the distance of the limiting rod 4 within the limiting sleeve 3 needs to be changed, the limiting handle 12 can be rotated to a horizontal position to slide, making the height adjustment of the handle 5 more convenient. One end of the limiting spring is fixedly connected to the inner wall of the limiting rod 4, and the other end is fixedly connected to the outer wall of the limiting handle 12. An annular notched groove is formed on the outer wall of the side end of the limiting rod 4. The limiting handle 12 rotates within the groove, and one end of the limiting spring is at the height of the inner wall of the groove in the limiting rod 4. The limiting rod 4 remains vertical when not under tension, ensuring its stability. A snap-fit ​​block 11, square in shape, is elastically connected to the upper outer wall of the hinge support 8 via a snap-fit ​​spring. The snap-fit ​​block 11 snaps onto the rotating shaft of the hinge support 8. One end of the snap-fit ​​spring is fixedly connected to the inner wall of the snap-fit ​​block 11, and the other end is fixedly connected to the outer wall of the hinge support 8. The snap-fit ​​spring ensures that the snap-fit ​​block 11 remains stable within the square groove at the upper end of the hinge support 8 when not under tension. A support rod 5 is fixedly connected to the outer wall of the limiting rod 4, providing support and stability. A telescopic rod 6 is fixedly connected to the outer wall of the support rod 5. The rod 6 keeps the handrail 5 fixed and does not move. The tail end of the telescopic rod 6 is hinged to the outer wall of the stabilizing bracket 1. There are six sets of telescopic rods 6. The six sets of telescopic rods 6 are divided into two sets and hinged to the outer walls of two sets of stabilizing brackets 1. The side outer wall of the stabilizing bracket 1 is rotatably connected to the hinge rod 9. There are two sets of hinge rods 9. The two sets of hinge rods 9 are rotatably connected by nuts 10. The hinge rods 9 connect the two sets of stabilizing brackets 1, so that they can be pulled apart to form a triangular shape. There are four sets of hinge rods 9. All four sets of hinge rods 9 are rotatably connected to the outer wall of nuts 10. The four sets of hinge rods 9 are respectively rotatably connected to both sides of the stabilizing bracket 1. The outer wall of the stabilizing bracket 1 is fixedly connected to the foot rod 2.

[0028] Furthermore, a fixing rod 15 is fixedly connected to the outer wall of the side end of the stabilizing bracket 1. A ring is fixedly connected to the outer wall of the fixing rod 15, and the ring is rotatably connected to the inner wall of the rotating rod 14 to prevent it from slipping. The rotating rod 14 is rotatably connected to the outer wall of the fixing rod 15. The rotating rod 14 can bring the shelf 7 between the two sets of stabilizing brackets 1, so that it will not affect the placement of the stabilizing bracket 1 and reduce the possibility of collision. A positioning block 13 is elastically connected to the inner wall of the rotating rod 14 through a positioning spring. The positioning block 13 is fixed in the groove of the shelf 7 by the pressure of the positioning spring. The two ends of the positioning block 13 fix the shelf 7 so that it cannot rotate. One end of the positioning spring is fixedly connected to the inner wall of the rotating rod 14, and the other end of the positioning spring is fixedly connected to the outer wall of the positioning block 13. The positioning spring is compressed by the rotating rod 14 and transmits pressure to the positioning block 13. The outer wall of the shelf 7 and the positioning block 13 are slidably connected to the inner wall of the shelf 7. The shelf 7 is rotatably connected to the outer wall of the rotating rod 14. The shelf 7 can be used by the user to place items. The upper end of the shelf 7 is fixed with a magnet so that the shelf 7 can be fixed and will not slip out when placed between the stable brackets 1. The inner wall of the rotating rod 14 is elastically connected to the fixing block 16 by a fixing spring. The side end of the fixing rod 15 has a groove. When the fixing block 16 is engaged in the groove of the fixing rod 15, the shelf 7 can be kept horizontal and will not rotate. One end of the fixing spring is fixedly connected to the inner wall of the rotating rod 14, and the other end of the fixing spring is fixedly connected to the outer wall of the fixing block 16. The fixing spring can fix the fixing block 16 in the groove of the fixing rod 15 and will not move. The outer wall of the fixing block 16 is slidably connected to the inner wall of the fixing block 16.

[0029] In this invention, during use, the stabilizing bracket 1 is pulled apart at both ends to form a stable triangle. Then, the rotating rod 14 is rotated to a horizontal position. At this time, the fixing block 16 slides into the groove of the fixing rod 15 under the pressure of the fixing spring, stabilizing the rotating rod 14. Then, the shelf 7 is rotated to a horizontal position. The positioning block 13 slides into the interior of the shelf 7 under the pressure of the positioning spring, maintaining stability and preventing slippage. The locking block 11 of the hinge support 8 of the stabilizing bracket 1 at the working end is pulled upward, and the locking block 11 is rotated so that the handle 5 rotates to a right angle with the stabilizing bracket 1. Then, it is released. The locking block 11 slides into the square groove of the hinge support 8 under the pressure of the locking spring and remains fixed. Then, the limiting handle 12 is pulled to the horizontal position, and the limiting rod 4 is slid to the predetermined position as needed. The limiting handle 12 is released, and it rotates to the vertical position under the tension of the limiting spring so that the position of the handrail 5 is fixed. After use, the locking block 11 is pulled and the handrail 5 is rotated to keep it horizontal with the stabilizing bracket 1. The stabilizing bracket 1 is retracted, and the positioning block 13 is pulled out to keep the shelf 7 vertical. The fixing block 16 is pulled out and the shelf 7 is rotated to retract to the middle of the stabilizing bracket 1.
