Abstract
Description
Technical Field
[0001] This utility model belongs to the field of luggage technology, and in particular relates to an environmentally friendly, waterproof and wear-resistant luggage made of a durable material. Background Technology
[0002] A suitcase, also known as a luggage box or rolling case, is commonly used when traveling. It's a type of luggage carried to hold belongings. Typically, suitcases are used to store clothing, personal care items, and souvenirs needed for the trip.
[0003] When traveling long distances, suitcases are usually filled with many items and are quite heavy. When moving on flat surfaces, they are relatively easy to move because of the wheels. However, when encountering stairs, people with less strength will find it difficult to move the suitcase and may even encounter danger. Therefore, an environmentally friendly, waterproof and wear-resistant suitcase made of durable materials is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide an environmentally friendly, waterproof, and wear-resistant suitcase. By adjusting the angle of the rotating belt, the suitcase can be easily moved up and down stairs, avoiding manual handling and reducing the difficulty of going upstairs. This makes it easier for people with less strength to use. At the same time, when going downstairs, the speed reduction frame can increase the friction of the rotating roller to prevent excessive speed when going downstairs, thereby improving the safety and flexibility of use and solving existing technical problems.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] An environmentally friendly, waterproof, and wear-resistant suitcase made of a waterproof material includes: a suitcase body; a fixed base is fixedly connected to one side of the suitcase body; a mounting frame is rotatably connected inside the fixed base; two through-type rotating rollers are rotatably connected between the two sides of the mounting frame; a rotating belt is driven between the two rotating rollers; and adjustment components for adjusting the angle of the mounting frame are provided on both sides of the mounting frame. By installing a rotating belt on one side of the suitcase body, the angle of the rotating belt can be adjusted when going up and down stairs outdoors, making it easier for the suitcase to go up and down stairs, avoiding manual carrying of the suitcase, reducing the difficulty of going upstairs, and making it convenient for people with less strength to use.
[0007] The adjustment assembly includes a mounting base, a slide rail, and multiple insertion holes. The mounting base is fixed to one side of the housing. The slide rail is located on one side of the mounting frame. A slider is slidably connected inside the slide rail. A support rod is rotatably connected between the slider and the mounting base. A through pin is threaded to one side of the slider. Multiple insertion holes are located on one side of the mounting frame and are arranged vertically. The pin is inserted into one of the insertion holes.
[0008] As a further embodiment of this utility model, a rubber sleeve is fixedly installed at one end of the rotating roller located at the top. A threaded rod is rotatably connected to the top of the mounting frame, and a speed reduction frame is threadedly connected to the circumference of the threaded rod. The bottom of the speed reduction frame is located above the rubber sleeve, and the speed reduction frame slides on one side of the mounting frame. By setting the speed reduction frame, when going down the stairs, the speed reduction frame abuts against the rubber sleeve, thereby increasing the friction force when the rotating roller rotates, preventing the speed of going down the stairs from being too fast, and improving the safety and flexibility of use.
[0009] As a further embodiment of this utility model, a protective shell is fixedly connected to the top of the mounting frame, and a knob is fixedly installed on the top of the threaded rod through the protective shell.
[0010] As a further embodiment of this utility model, a plurality of support rollers for supporting the rotating belt are rotatably connected between the two sides of the mounting frame.
[0011] As a further improvement of this utility model, multiple casters are fixedly installed at the bottom of the box.
[0012] As a further improvement of this utility model, the outer wall of the rotating belt is integrally formed with multiple anti-slip strips.
[0013] As a further improvement of this utility model, the box body is made of PP material.
[0014] In this application, during use, pulling the handle on the box allows the box to move normally on a flat surface via the casters. When encountering stairs, loosening the pivot pin and then rotating the mounting frame tilts the frame. Rotating the pivot pin inserts it into one of the holes, maintaining a stable angle between the mounting frame and the box with the support of the struts. Tilting the box then brings the rotating belt into contact with the stairs, and pulling the box again allows it to move upwards along the stairs, avoiding manual carrying and reducing the difficulty of climbing stairs, making it convenient for people with less strength. When descending stairs, the same method can be used... The same method is used to descend the stairs, but when descending, the screw rod is turned by the knob, which drives the deceleration frame to move downwards. The deceleration frame contacts the rubber sleeve, thereby increasing the friction of the rotating roller when descending, preventing the descending speed from being too fast, and improving the safety and flexibility of use. When the suitcase is laid down and moved to the under-bed or other small spaces for storage, the rotation of the transmission belt can also reduce the difficulty of placing the suitcase horizontally and prevent the suitcase from rubbing. The suitcase is made of PP material, which is very tough and can withstand a lot of pressure. At the same time, it has excellent waterproof performance, which can keep the luggage dry even in rainy weather.
[0015] The embodiments of this utility model have the following beneficial effects:
[0016] In this utility model, by installing a rotating belt on one side of the box, the angle of the rotating belt can be adjusted when going up and down stairs outdoors, thereby making it easier for the box to go up and down stairs, avoiding manual carrying of the box, reducing the difficulty of going upstairs, and making it easier for people with less strength to use.
[0017] In this utility model, by setting up a deceleration frame, the deceleration frame comes into contact with the rubber sleeve when going down the stairs, thereby increasing the friction of the rotating roller when going down the stairs, preventing the speed of going down the stairs from being too fast, and improving the safety and flexibility of use;
[0018] In this invention, by adjusting the angle of the rotating belt, the box can be easily moved up and down stairs, avoiding manual handling of the box, reducing the difficulty of going upstairs, and making it easier for people with less strength to use. At the same time, when going downstairs, the speed reduction frame can be used to increase the friction of the rotating roller, preventing the speed of going downstairs from being too fast, and improving the safety and flexibility of use.
[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
