Description

Tool box

The present invention relates to kits.

The tool box is a container specially used for accommodating various tools and parts, and has the dual functions of convenient carrying and protection. Traditional tool boxes focus on protection, so they are often made of metal materials. However, metal shells are not only bulky, but also prone to rust, sharp edges and easy to be cut or damaged. Therefore, most of today's tool boxes are made of plastic. .

However, the structural strength of the tool box made of plastic is relatively fragile. When a locking element, a hinge and other connecting elements are added to the box body, the structure of the box body will be damaged and the structure will be fragile. When the bearing weight is used for a period of time, , the box body often has the problem of bending deformation at the installation of the connecting element, and even cracking in severe cases, resulting in a short service life.

Therefore, it is necessary to provide a novel and progressive tool box to solve the above-mentioned problems.

The main purpose of the present invention is to provide a tool box, which is combined with a plastic rib through a metal frame, and achieves a balance between structural strength and light weight through the combination of different materials; and, The positioning member used to locate the locking unit completely penetrates the frame, so that the force is mainly distributed on the relatively hard metal frame, so as to ensure the structural integrity of the plastic rib.

To achieve the above objects, the present invention provides a tool box, comprising: a first casing, a second casing and at least one locking component. The first casing includes a first body and a first frame, the first body includes a first rib, the first frame includes two first side parts and a first cover part, the second second One side portion is laterally connected to two opposite sides of the first cover portion to jointly define a first covering space and a first opening, and the first protruding rib is inserted into the first bag through the first opening. Covering the space, the material of the first protruding rib is plastic, and the material of the first frame is metal. The second casing can be connected to the first casing relatively openly and closed, the second casing includes a second body and a second frame, the second body includes a second rib, and the second frame It includes two second side parts and a second cover part, the two second side parts are respectively laterally connected to two opposite sides of the second cover part to jointly define a second covering space and a second opening, The second protruding rib is inserted into the second cladding space through the second opening, the material of the second protruding rib is plastic, and the material of the second frame is metal. When the second casings are closed to each other, the first cover part and the second cover part abut against each other; the at least one locking component includes a first locking unit, a second locking unit, a plurality of first positioning members and A plurality of second positioning members, each of the first positioning members includes a first connecting portion and two first blocking portions, the first connecting portion penetrates the first locking unit, the first protruding rib and the two first side portions , the two first blocking parts are laterally protrudingly connected to opposite ends of the first connecting part, in the direction of the first connecting part passing through, the two first blocking parts are respectively connected with the first locking unit and the One of the two first side portions away from one of the first locking units is in an interference relationship, so that the first locking unit is connected and positioned on one of the first side portions, and each of the second positioning members includes a second connecting portion and two second blocking portions, the second connecting portion penetrates through the second locking unit, the second protruding rib and the two second side portions, the two second blocking portions are laterally protruded and connected to the second connecting portion the opposite ends, in the direction of the second connecting part On the above, the two second blocking portions are in an interference relationship with the second locking unit and one of the two second side portions away from the second locking unit, so that the second locking unit is connected and positioned at a On the second side, the second locking unit can be connected with the first locking unit so that the second casing cannot be opened and closed relative to the first casing.
