Description

Technical Field

[0001] The utility model belongs to the field of protective appliances, and particularly relates to a safety protection box for a universal guide wheel. Background Art

[0002] With the development of technology, instruments in many fields are often high-precision instruments. During long-distance transportation and operation in harsh environments, a large number of safety protection boxes are often required as auxiliary tools.

[0003] The prior art publication number CN219742051U discloses a new type of safety protection box, which is characterized in that it includes an upper shell assembly, a lower shell assembly, a partition board, a buckle assembly, a tire assembly, and a pull rod assembly. A partition board is installed in the upper shell assembly and the lower shell assembly. The rear sides of the upper shell assembly and the lower shell assembly are connected. Buckle assemblies are installed on the front side, left side, and right side of the upper shell assembly. The tire assembly is installed at the tail of the lower shell assembly, and the pull rod assembly is installed outside the lower shell assembly. The buckle assembly includes a buckle bracket, a first support rod, a second support rod, a buckle, and a spring. The upper end of the buckle bracket is installed with a first support rod, and the buckle is installed on the buckle bracket through the second support rod. The lower end of the buckle is connected with a spring. In the safety protection box of the utility model, a spring is arranged inside the buckle, and the spring can better protect the buckle when opening and closing the box. A clamping column is arranged on the lower shell of the safety protection box to prevent the shell from being damaged when placing or rolling.

[0004] However, the prior art publication number CN219742051U discloses a new type of safety protection box, which cannot be moved by rotating the angle arbitrarily during use and can only be moved in a fixed direction. It is easy to roll to the user's feet when moving. When it rains or passes through a water accumulation area, water often enters the trunk through the holes of the wheels, resulting in the items inside the trunk being soaked. At present, at the connection between the upper shell and the lower shell of the trunk, there is usually no damping design, and the upper shell is easy to directly fall to the ground when opened, which is extremely easy to damage the upper shell. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a safety protection box for a universal guide wheel, aiming to solve the problems existing in the above background art. To achieve the above purpose, the technical solution adopted by the utility model is:

The universal wheel assembly is installed at the tail of the lower shell assembly, and the pull rod assembly is installed outside the lower shell assembly. 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 at 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.

[0007] Preferably, the upper shell assembly includes an upper shell bracket and a lock, the upper shell adopts a reinforced gluten design, and multiple locks are installed at the upper end of the front side of the upper shell.

[0008] Preferably, the lower shell assembly includes a lower shell bracket, a clamping post, an exhaust valve and a handle. Multiple handles are installed on the front side, left side and right side of the lower shell bracket. Multiple exhaust valves are installed on the front side of the lower shell bracket. Multiple clamping posts are installed on the outer side of the lower shell bracket.

[0009] Preferably, the pull rod assembly includes a pull rod, a pull rod switch and a fixing plate, and the pull rod is fixed to the fixing plate through the pull rod switch.

[0010] Preferably, the pull rod assembly is connected to the lower shell assembly in an embedded manner, and the universal wheel assembly is connected to the lower shell assembly in an embedded manner.

[0011] Preferably, there is a damping design when the hinge joint of the upper shell and the lower shell is opened and closed.

[0012] Preferably, a plurality of additional sealing rings are arranged inside the universal wheel fixing shell, and the universal wheel fixing shell can be sealed and waterproof with the upper shell assembly and the lower shell assembly through the additional sealing rings.

[0013] The beneficial effects of the present utility model are as follows: through the damping design provided at the hinge joint of the upper shell and the lower shell, it is avoided that the upper shell directly drops and contacts the ground when the upper shell is opened, thereby damaging the upper shell; through the universal wheel assembly, the box body can freely change directions, making the box body more convenient to move; through the arrangement of a plurality of additional sealing rings inside the universal wheel fixing shell, the box will not enter the inside of the box body from the universal wheel fixing shell when passing through a water accumulation area or on a rainy day, thereby wetting the items inside the box body.
