Technical Field

[0001] The utility model relates to the technical field of roto-molding boxes, in particular to a roto-molding box with anti-ultraviolet function. Background Art

[0002] Roto-molded boxes are made of plastic as the main raw material through a single rotational molding process. They are made of high-molecular polyethylene material, have stable performance, are resistant to high and low temperatures, are non-toxic and odorless, have the advantages of being UV resistant, light weight, low cost, corrosion resistant, and having a long service life. They are often used to store war preparedness supplies.

[0003] Roto-molded boxes are usually used in scenes such as fire rescue, outdoor camping supplies, and military logistics support. Whether it is used for rescue, field training, airdrop, or sea transportation, roto-molded boxes can effectively ensure that the items in the box are safe and sound.

[0004] The existing anti-ultraviolet roto-molding boxes have certain disadvantages when in use. The existing roto-molding boxes are not easy to move. Even if universal wheels are added to the bottom of some roto-molding boxes, this makes the roto-molding boxes relatively unstable when placed and lacks practicality. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a roto-molding box with anti-ultraviolet function, which can make the roto-molding box more convenient to move and at the same time make the roto-molding box more stable when not moving, thereby improving the practicality.

The universal wheel 6 is clamped on the U-shaped card seat 7. A chamber is provided inside the flip seat 5. Both axial ends of the flip seat 5 are provided with rectangular notches connected to the chamber. Two groups of T-shaped top plates 8 are provided on the flip seat 5 through the symmetrical sliding of the rectangular notches. Three groups of springs 9 are fixedly connected equidistantly between the two groups of T-shaped top plates 8. The outer ends of the two groups of T-shaped top plates 8 are respectively against the front and rear walls of the storage slot; when in use, the universal wheel 6 is initially clamped on the U-shaped card seat 7, the universal wheel 6 is in a horizontal state, and the spring 9 is in a compressed state. The thrust generated by the compression of the spring 9 causes the outer ends of the T-shaped top plates 8 to The universal wheel 6 is tightly pressed against the front and rear inner walls of the storage groove so that the universal wheel 6 can be stored in the storage groove. At this time, when the rotational molding box 1 is placed, the bottom of the rotational molding box 1 is flat and keeps in contact with the placement. When it needs to be moved, the rotational molding box 1 is lifted, the universal wheel 6 is removed from the U-shaped card seat 7 and rotated to be vertically downward. During the rotation process, the universal wheel 6 drives the flip seat 5 to rotate, so that the flip seat 5 drives the T-shaped top plate 8 to gradually rotate from a vertical state to a horizontal state. When the flip seat 5 drives the T-shaped top plate 8 to rotate to a horizontal state, the top of the T-shaped top plate 8 is lower than the bottom edge of the storage groove, and the top of the T-shaped top plate 8 is level with the bottom end of the rotational molding box 1, so that the spring 9 starts to rebound. , under the rebound action of spring 9, the T-shaped top plate 8 is pushed to slide outward, so that the T-shaped top plate 8 is blocked on both sides of the storage groove of the roto-molding box 1, and the universal wheel 6 is put down, and then the roto-molding box 1 can be pushed to move. When the roto-molding box 1 does not need to be moved, the T-shaped top plate 8 is squeezed by hand to make the T-shaped top plate 8 slide inward to the outside and coincide with the front and rear inner walls of the storage groove, and then the universal wheel 6 is rotated to horizontal, so that the universal wheel 6 is re-stuck on the U-shaped seat 7, and the universal wheel 6 can be folded up, so that the bottom of the roto-molding box 1 is in contact with the placement, thereby facilitating the movement of the roto-molding box, and at the same time making the roto-molding box more stable when not moving, thereby improving practicality.

[0022] The left and right upper parts of the rotational molding box 1 are fixedly provided with connecting seats 10, and the two sets of connecting seats 10 are rotatably mounted with carrying handles 11; by providing the connecting seats 10 and the carrying handles 11, the rotational molding box 1 can be made more convenient when carried.

[0023] The outer walls of the two groups of the carrying handles 11 are fixedly sleeved with anti-skid handle covers 12; by providing the anti-skid handle covers 12, it is possible to prevent the hands from slipping when holding the carrying handles 11 to carry the rotationally molded box 1.

[0025] The four corners of the bottom of the roto-molded box 1 are fixedly connected with anti-skid rubber pads 14; by providing the anti-skid rubber pads 14, the friction with the placement can be increased, so that the roto-molded box 1 can avoid slipping when being placed.

[0026] The utility model is a roto-molding box with anti-ultraviolet function. Its working principle is that when in use, the universal wheel 6 is initially stuck on the U-shaped seat 7, the universal wheel 6 is in a horizontal state, and the spring 9 is in a compressed state. The thrust generated by the compression of the spring 9 makes the outer end of the T-shaped top plate 8 tightly against the front and rear inner walls of the storage groove, so that the universal wheel 6 can be stored in the storage groove. At this time, when the roto-molded box body 1 is placed, the bottom of the roto-molded box body 1 is flat and keeps in contact with the placement. When it needs to be moved, the roto-molded box body 1 is lifted, the universal wheel 6 is removed from the U-shaped seat 7 and rotated to be vertically downward. During the rotation process, the universal wheel 6 drives the flip seat 5 to rotate, so that the flip seat 5 drives the T-shaped top plate 8 to gradually rotate from the vertical state to the horizontal state. When the flip seat 5 drives the T-shaped top plate 8 to rotate to a horizontal state, the top end of the T-shaped top plate 8 is lower than the bottom edge of the storage groove, and the top end of the T-shaped top plate 8 is level with the bottom end of the rotational molding box 1, so that the spring 9 starts to rebound. Under the rebound action of the spring 9, the T-shaped top plate 8 is pushed to slide outward, so that the T-shaped top plate 8 is blocked on both sides of the storage groove of the rotational molding box 1, and the universal wheel 6 is put down, and then the rotational molding box 1 can be pushed to move. When the rotational molding box 1 does not need to be moved, the T-shaped top plate 8 is squeezed by hand to make the T-shaped top plate 8 slide inward to the outside and coincide with the front and rear inner walls of the storage groove, and then the universal wheel 6 is rotated to a horizontal state, so that the universal wheel 6 is re-stuck on the U-shaped seat 7, and the universal wheel 6 can be folded up, so that the bottom of the rotational molding box 1 is in contact with the placement position.

[0027] The installation method, connection method or setting method of the rotomolding box with anti-ultraviolet function of the utility model are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects; the lock of the rotomolding box with anti-ultraviolet function of the utility model is purchased on the market, and technicians in this industry only need to install and operate it according to the accompanying instruction manual.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
