Description

Technical Field

[0001] This utility model relates to the technical field of environmentally friendly and biodegradable material suitcases, specifically an environmentally friendly and biodegradable material suitcase. Background Technology

[0002] The materials and structural design of the suitcase effectively protect the contents from external impacts, compression, and weather changes.

[0003] For example, a suitcase with application publication number "CN108835802A" has wheels rotatably connected to the suitcase body. The suitcase body has locking blocks, the wheel seats have locking grooves, and the suitcase body has recesses to accommodate the wheels, allowing them to be easily stored within the recesses and reducing the space occupied by the suitcase when stored. The side walls of the assembly space have concave grooves, and the wheel seats have convex grooves. The convex grooves and concave grooves cooperate to assist in positioning, improving the stability of the suitcase during use. However, during use, the outer tubing of the suitcase is easily damaged, such as the wheels, especially during airport baggage handling. When the suitcase slides down, it may hit the wall of the equipment, and if the wheels are hit directly, they are easily damaged, rendering the suitcase unusable and shortening its lifespan. Utility Model Content

[0004] The purpose of this invention is to solve the problem of suitcases becoming unusable and shortening their lifespan by proposing an environmentally friendly and biodegradable material suitcase.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an environmentally friendly and biodegradable suitcase, including upright panels, the tops of which are fixedly connected to the bottom of the suitcase, the bottom of the suitcase is connected to a protective structure, a pull rod is slidably connected to a groove on the rear of the outer wall of the suitcase, and a protective sleeve is fixedly connected to the top of the outer wall of the pull rod.

[0007] Preferably, the protective structure includes a cover and a crossbar. The top of the cover fits against the bottom of the suitcase. The inner circular opening of the cover is slidably connected to the outer wall of the crossbar. A circular plate is fixed to the inner end of the crossbar. A spring is sleeved on the outer wall of the crossbar. The two ends of the spring are fixed to the outer wall of the circular plate and the inner wall of the cover, respectively.

[0008] Preferably, the outer end of the crossbar is inserted into the inner wall of the vertical plate.

[0009] Preferably, the suitcase has multiple casters fixed to the four corners of its bottom.

[0010] Preferably, the suitcase has a handle fixed to its right side.

[0011] This utility model proposes an environmentally friendly and biodegradable suitcase with the following advantages: The protective structure involves inserting a hand from bottom to top into the inside of the cover, then pushing the circular plate inwards. This causes the circular plate, along with a crossbar, to move inwards until the end of the moving crossbar is flush with the circular opening on the outer wall of the cover. Simultaneously, the circular plate applies pressure to the spring, bringing the top of the cover into contact with the bottom of the suitcase. At this point, the casters are positioned in the opening on the outer wall of the cover. Then, the circular plate is released, and the spring, having lost its tension, provides a rebound force, causing the circular plate, along with the crossbar, to move outwards. The outer end of the moving crossbar engages with the inner wall of the upright plate, thus securing the cover. The cover protects the casters from impact damage, ensuring normal use and extending the suitcase's lifespan. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings: Example 1:

[0018] Please see Figure 1-4 In this embodiment, an environmentally friendly and biodegradable suitcase includes a stand panel 1. The tops of multiple stand panels 1 are fixedly connected to the bottom of the suitcase 4. The suitcase 4 is made of biocarbonate. A protective structure 2 is connected to the bottom of the suitcase 4. A pull rod 7 is slidably connected to the groove at the rear of the outer wall of the suitcase 4. A protective sleeve 8 is fixedly connected to the top of the outer wall of the pull rod 7. The protective sleeve 8 is made of rubber and protects the hands.

[0019] The protective structure 2 includes a cover 201 and a crossbar 202. The top of the cover 201 fits against the bottom of the suitcase 4. The cover 201 is made of carbon fiber. The inner wall of the cover 201 is slidably connected to the outer wall of the crossbar 202. The crossbar 202 slides left and right through the inner wall of the cover 201 when subjected to force. A circular plate 203 is fixed to the inner end of the crossbar 202. The circular plate 203 facilitates the movement of the crossbar 202. A spring 204 is sleeved on the outer wall of the crossbar 202. The two ends of the spring 204 are fixed to the outer wall of the circular plate 203 and the inner wall of the cover 201, respectively. After the circular plate 203 is subjected to force and moves inward, it rebounds due to the elasticity of the spring 204. The outer end of the crossbar 202 is inserted into the inner wall of the upright plate 1.

[0020] By inserting the hand from bottom to top into the protective cover 201 through the protective structure 2, the hand then pushes the circular plate 203 inward, causing the circular plate 203 to move inward along with the crossbar 202. The end of the moving crossbar 202 is flush with the circular opening on the outer wall of the protective cover 201. At the same time, the circular plate 203 applies pressure to the spring 204, and then the top of the protective cover 201 is brought into contact with the bottom of the suitcase 4. At this time, the universal wheel 5 is located in the opening on the outer wall of the protective cover 201. Then, the circular plate 203 is released, and the spring 204 loses its tension and provides a rebound force, causing the circular plate 203 to move outward along with the crossbar 202. The end of the moving crossbar 202 is inserted into the inner wall of the upright plate 1, thus completing the fixation of the protective cover 201. The protective cover 201 provides protection for the universal wheel 5, preventing it from being damaged by impact, ensuring the normal use of the suitcase, and guaranteeing the service life of the suitcase.

[0021] The bottom of the suitcase 4 has multiple casters 5 fixed to the four corners. The right side of the suitcase 4 has a handle 6 fixed to it. The handle 6 can lift the suitcase 4, making it convenient to carry it up stairs.

[0022] Working principle:

[0023] Suitcase usage:

[0024] By holding the protective sleeve 8 and pulling it upwards, the pull rod 7 can be moved upwards and extended. Then, with the protective sleeve 8 pulling the pull rod 7, it can be moved in one direction, thereby allowing the suitcase 4 to move with the bottom casters 5, thus realizing the position movement of the suitcase 4. At the same time, the suitcase 4 provides good strength and biodegradability through its own biocarbonate material. When the suitcase 4 is laid flat on the ground, the buckles on the outer wall of the suitcase 4 can be opened to open the suitcase 4 in half. Then, the protective structure 2 and the placed items can be put in, and then the suitcase 4 can be closed and locked.

[0025] Protection during luggage transportation:

[0026] When checking in the suitcase, the protective structure 2 inside the suitcase 4 can be removed. Then, insert your hand from bottom to top into the protective cover 201, and push the round plate 203 inward, so that the round plate 203 moves inward along with the crossbar 202. The end of the moving crossbar 202 is flush with the round opening on the outer wall of the protective cover 201. At the same time, the round plate 203 applies pressure to the spring 204. Then, the top of the protective cover 201 is placed against the bottom of the suitcase 4. At this time, the universal wheel 5 is located in the opening on the outer wall of the protective cover 201. Then, release the round plate 203. The spring 204 loses tension and provides a rebound force, so that the round plate 203 moves outward along with the crossbar 202. The end of the moving crossbar 202 is inserted into the inner wall of the upright plate 1, thus fixing the protective cover 201. The protective cover 201 protects the universal wheel 5 and prevents it from being damaged by impact.

[0027] After the suitcase 4 has been checked in, insert your hand into the inside of the cover 201 and pull the round plate 203 inward. This will cause the round plate 203 to move inward along with the crossbar 202. At this point, the crossbar 202 will detach from the upright plate 1. Then, move the cover 201 downward to detach it from the suitcase 4. Finally, put the cover 201 back into the inside of the suitcase 4. The cover 201 is not a large structure, and two covers 201 stacked inside the suitcase 4 will not take up too much space. Example 2:

[0028] Please see Figure 1-4 In this embodiment, an environmentally friendly and biodegradable suitcase also includes vertical panels 3, and the outer walls of multiple vertical panels 3 are respectively fixed to the front and rear sides of the suitcase body 4.

[0029] Working principle:

[0030] The vertical panel 3 provides impact protection to the front and back sides of the suitcase 4 through the superior strength of its carbon fiber material. At the same time, the texture of the carbon fiber material itself can also improve the aesthetics of the suitcase 4. Moreover, the carbon fiber material is recyclable and will not affect the degradation of the suitcase 4.

[0031] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
