Description

Technical Field

[0001] This utility model relates to the field of ladder technology, specifically a quick-release and assembleable household safety non-slip aluminum ladder. Background Technology

[0002] A ladder is a common household tool for climbing. A ladder usually consists of a ladder frame and steps. Traditional ladder frames and steps are connected by bolts or welding, making the whole device inconvenient to store. Moreover, when a part is damaged, such as a step bending or one end of a step becoming loose from the ladder frame, it is inconvenient to disassemble and replace, affecting the overall service life. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-assembly, safe, non-slip aluminum ladder for home use.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release and assembleable household safety anti-slip aluminum ladder, comprising side plates, crossbeams, and connectors. The side plates are arranged in two symmetrical sets, with the crossbeams positioned between the two sets of side plates. The crossbeams are connected to the side plates via connectors. The connectors include a handle, a worm gear, a worm wheel, a screw, and a plug. A movable groove is provided in the center of the crossbeam, and the worm wheel and worm gear are disposed within the movable groove. Storage grooves are symmetrically arranged on the left and right sides of the crossbeam, and a screw and a plug are rotatably disposed within the storage grooves. The plug is threaded to one end of the screw, and the other end of the screw extends into the movable groove and is connected to the center of the worm wheel. The worm gear meshes with the worm wheel, and the lower part of the worm gear passes through the crossbeam and is connected to the handle. Slots adapted to the plugs are provided on both sets of side plates, and a notch adapted to the slot near the side wall of the crossbeam is also provided below the plug.

[0007] To ensure stable support of the bottom wall of the side plate, this utility model is improved by providing a friction sleeve below the side plate.

[0008] To ensure its stability under tilt angles, this invention is improved by providing several sets of friction flanges below the friction sleeve.

[0009] Furthermore, in order to ensure the stability of the connection between the plug and the side plate, the present invention is improved by providing a first pin hole at the end of the plug away from the handle, and a second pin hole through the slot on the front side of the side plate. The connector also includes a pin, which is inserted into the first pin hole and the second pin hole.

[0010] To facilitate stable insertion and removal of the assembly pin, this utility model is improved by providing an end protruding from the side plate, and a magnetic block that engages with the pin is embedded in the slot.

[0011] Preferably, the handle is also provided with friction texture.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a quick-release and assembly type household safety non-slip aluminum ladder, which has the following beneficial effects:

[0014] This quick-assembly, modular, safe, non-slip aluminum ladder for home use works by turning the handle, which rotates the worm gear. The worm gear meshes with a worm wheel, driving the worm wheel to rotate, which in turn causes the screw to rotate, allowing the insert to move along the screw within its storage slot. When the insert retracts into the storage slot, the crossbeam and side panel can be easily separated; conversely, turning the handle in the opposite direction extends the insert, allowing it to insert into the slot of the side panel for quick assembly. This design makes it easy to replace partially damaged parts (such as the crossbeam corresponding to the steps) and also facilitates overall storage, saving home storage space.

[0020] 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.

[0021] Please see Figure 1-4A quick-assembly, modular, safe, non-slip aluminum ladder for home use includes side panels 1, crossbeams 2, and connectors. The side panels 1 are arranged in two symmetrical sets, with the crossbeams 2 positioned between them. The crossbeams 2 are connected to the side panels 1 via connectors, which include handles 3, worm gears 4, worm wheels 5, screws 6, and inserts 7. A movable groove is located at the center of the crossbeams 2, within which the worm wheels 5 and worm gears 4 are housed. Storage grooves are symmetrically arranged on the left and right sides of the crossbeams 2. A screw 6 and a plug 7 are rotatably disposed inside the storage slot. The plug 7 is threadedly connected to one end of the screw 6, and the other end of the screw 6 extends into the movable slot and is connected to the center of the worm gear 5. The worm 4 meshes with the worm gear 5. The lower part of the worm 4 passes through the crossbeam 2 and is connected to the handle 3. The two sets of side plates 1 are provided with slots that are adapted to the plug 7. The plug 7 is also provided with a notch 8 below it that is adapted to the slot near the side wall of the crossbeam 2.

[0022] When assembling the ladder, first place the two sets of side panels 1 in position, pick up the crossbeam 2, and align the insert 7 with the slot on the side panel 1. Next, turn the handle 3 clockwise. The handle 3 drives the worm gear 4 to rotate. Since the worm gear 4 and the worm wheel 5 mesh with each other, the rotation of the worm gear 4 causes the worm wheel 5 to start rotating. The center of the worm wheel 5 is connected to the screw 6, which rotates along with it. The insert 7 is threaded to one end of the screw 6. As the screw 6 rotates, the insert 7 extends outward along the storage groove until the insert 7 is fully inserted into the slot of the side panel 1. At this time, the notch 8 below the insert 7 fits tightly with the side wall of the slot near the crossbeam 2, thus initially completing the connection between the crossbeam 2 and the side panel 1. Finally, insert the pin 11 into the first pin hole of the insert 7 and the second pin hole of the side panel 1. With the help of the magnetic block 13 to attract and guide the pin 11, the pin 11 is easily inserted and tightened, further stabilizing the connection. The ladder assembly is now complete.

[0023] To disassemble, first remove pin 11 to release the secondary reinforcement. Then, push the crossbeam 2 upwards so that the notch 8 no longer contacts the side wall of the slot, making the slot an inverted L-shape. Turn the handle 3 counterclockwise, and the worm gear 4 will rotate in the opposite direction, causing the worm wheel 5 and the screw 6 to reverse. The insert 7 will retract into the storage groove along the screw 6. When the insert 7 is fully retracted into the storage groove, there is no longer any connection restriction between the crossbeam 2 and the side plate 1, and the two can be easily separated. The components can then be stored away. The operation is simple and convenient.

[0024] A friction sleeve 9 is also provided below the side panel 1. When the ladder is in use, the friction sleeve 9 below the side panel 1 is in direct contact with the ground. The friction sleeve 9 is made of a material with high friction, which increases the coefficient of friction with the ground. When placed on the ground, it can resist the horizontal sliding tendency of the ladder when subjected to external forces, keeping the ladder firmly in place. Several sets of friction flanges 10 are also provided below the friction sleeve 9. When the ladder is placed at an angle (such as when used against a wall), the friction flanges 10 below the friction sleeve 9 play a key role. These flanges will embed into the small unevenness of the ground or fit more closely to the ground texture, generating additional resistance and preventing the ladder from sliding when tilted due to the user's climbing movements, center of gravity shift, etc., ensuring safety and stability during the climbing process.

[0025] In this embodiment, the handle 3 is also provided with friction texture 14 to ensure the stability of the drive handle 3.
