Description

Technical Field

[0001] The utility model belongs to the field of safety protection boxes, and in particular relates to a novel safety protection box. Background Art

[0002] With the development of science and technology, instruments in many fields are often high-precision instruments. When transported over long distances or operated in harsh environments, a large number of safety protection boxes are often required as auxiliary tools.

[0003] The wheels of safety protection boxes currently on the market are often oriented in a fixed direction, and users often need time to change the direction when pushing or pulling the boxes. In addition, the universal wheels on the market are often connected to the boxes by hinges. On rainy days or when passing through puddle water, water often enters the suitcase through the holes in the wheels, causing the items inside the suitcase to be soaked. Currently, the connection between the upper shell and the lower shell of the suitcase usually has no damping design, so the upper shell is easily dropped to the ground when opened, which is very easy to damage the upper shell. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of safety protection box, aiming to solve the problems existing in the background technology. To achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A new type of safety protection box includes a shell assembly, a universal wheel assembly, a handle assembly and a pull rod assembly. Multiple universal wheel assemblies are installed at the bottom of the shell assembly, a handle assembly is installed on the top of the shell assembly, and a pull rod assembly is installed on the rear side of the shell assembly. The shell assembly can rotate freely through the universal wheel assembly, and the handle assembly and the handle assembly are used for grabbing and placing during use.

[0006] Preferably, the shell assembly includes an upper shell, a lower shell, a lock, a buckle, a post, an exhaust valve and a handle. The rear side of the upper shell is hinged to the rear side of the lower shell. The upper shell adopts a reinforced rib design. A plurality of locks are installed on the upper end of the front side of the upper shell, and a plurality of buckles are installed between the locks. A handle is installed on the front side of the lower shell, an exhaust valve is installed on the front side of the lower shell, and a plurality of posts are installed on the outer side of the lower shell.

[0007] Preferably, the universal wheel assembly includes a universal wheel fixing shell, a universal wheel fixing seat, a movable shaft, a universal wheel and a first pin, the universal wheel fixing seat is installed on the bottom of the universal wheel fixing shell through the movable shaft, and the universal wheel is installed inside the universal wheel fixing seat through the first pin.

[0008] Preferably, a plurality of sealing rings are arranged inside the universal wheel fixing shell, and the universal wheel fixing shell and the housing assembly are fixed with the sealing rings to be sealed and waterproof.

[0009] Preferably, the handle assembly includes a handle, a fixing block, a second pin and a first screw, the fixing block is installed on the top of the lower shell by a plurality of first screws distributed left and right, and the handle is fixed to the fixing block by a plurality of second pins.

[0010] Preferably, the pull rod assembly comprises a pull rod, a second screw and a pull rod fixing shell, the pull rod fixing shell is mounted on the bottom of the lower shell through a plurality of second screws, and the pull rod is mounted inside the pull rod fixing shell.

[0011] Preferably, the hinge between the upper shell and the lower shell has a damping design when opening and closing.

[0012] The beneficial effects of the utility model are as follows: a damping design is provided at the hinge between the upper shell and the lower shell to prevent the upper shell from directly falling and contacting the ground when the upper shell is opened, thereby preventing the upper shell from being damaged; the universal wheel assembly allows the box to change direction freely, making it more convenient to move the box; a plurality of sealing rings are provided inside the universal wheel fixed shell to prevent the box from entering the interior of the box from the universal wheel fixed shell when passing through a waterlogged area or on a rainy day, thereby preventing the items inside the box from getting wet.
