Description

Tool box structure

The invention relates to a tool box structure, in particular to a moving part of a tool box structure slidingly disposed on a first box body, the moving piece being displaced on the first box body, so that the second box body and the second box body are The moving parts are engaged, and the first box body and the second box system are buckled with the moving piece and are not easily detached.

As is known in the prior art, the conventional tool box structure is as described in U.S. Patent No. 4,138,151, which is based on a casing 1. The casing 1 is provided with an accommodating space 1a, and the accommodating space 1a is provided. The cover 1 is provided with a cover plate 3, and the cover plate 3 is pivotally disposed with the pivot portion 2, and the cover plate 3 is configured to close the accommodating space 1a. The cover plate 3 is closed. The first fastening member 5 is provided with a first fastening portion 5a, and the inner side of the accommodating space 1a is provided with a fastening groove 6 when the cover plate 3 is closed. The first fastening component 5 is disposed at the fastening groove 6 . The first fastening cavity 6 is fastened at one end of the fastening groove 6 , and the second fastening component 7 is supported by the second fastening component 7 . The first fastening portion 7 is provided with a first assembly portion 7a, and the first assembly portion 7a is coupled with the first housing 6a. The second fastening member is disposed at the fastening groove 6. 7 is provided with a second fastening portion 7b, which is away from the first assembly portion 7a, and the second fastening portion 7b is first with the first fastening member 5 The fastening portions 5a are engaged with each other.

However, the structure of the conventional tool box is missing: as shown in Figures 3, 4, 5 and 6 of the U.S. Gazette, the second fastening member 7 is in the form of an elastic body, and the first fastening member 5 is When the first fastening portion 5a is engaged with the second fastening portion 7b of the second fastening member 7, the first fastening portion 5a elastically deforms the second fastening portion 7b to engage with the first fastening portion 5b. When the second fastening component 7 is in the form of an elastic body, the fastening manner is less stable. If the casing 1 is accidentally dropped or strongly collided, the first fastening portion 5a is engaged with the second fastening portion. The portion 7b is relatively easy to disengage, and the cover plate 3 is automatically opened, causing the articles in the accommodating space 1a to fall, and the utility and safety thereof are insufficient.

In view of the lack of the tool box structure of the above-mentioned conventional patent case, the inventors have been engaged in the manufacturing experience of related industries for many years, and finally have a product of a tool box structure that can solve the drawbacks of the conventional use.

The second fastening component of the conventional tool box structure is an elastic body. When the first fastening component is engaged with the second fastening component, the first fastening component elastically deforms the second fastening component. And the second fastening component is less stable when it is elastic, and the first fastening component and the second fastening component are if the casing is accidentally dropped or strongly collided. The invention is related to a tool box structure, in particular, a moving member of a tool box structure is slidably disposed on the first box body, and the moving member is displaced on the first box body, so that The second box body is engaged with the moving member, and the first box body and the second box system are surely fastened by the moving member and are not easily detached.

A tool box structure, comprising: a first The box body is provided with a first pivot portion, a first sliding rail, a first abutting surface, a first chamber and a second chamber; a second box system is provided with a second pivot portion, the second pivot portion is coupled to the first a pivoting portion, the second box system is provided with a third chamber, the third chamber is opposite to the first chamber and the second chamber, and the third chamber is provided with a first a beveling surface and a first abutting portion; a control member is disposed at the first chamber, the control member is provided with an elastic portion, a pressing portion and a second abutting portion; a first elastic member is elastically biased a first sliding surface; a moving member is provided with a second sliding rail, the second sliding rail is slidably disposed with the first sliding rail, and the second sliding rail is provided with a second abutting surface to The first elastic member is elastically biased against the first abutting surface and the second abutting surface, and the moving member is provided with a convex block, and the convex portion is provided with a second inclined surface, the convex portion The block is provided with a third abutting portion and a fourth abutting portion, and the third abutting portion and the fourth abutting portion are abutted against the second abutting portion, so that the moving member cannot be the first Shift on the rail.

When the second casing is closed to the first casing, the pressing portion of the control member is pressed by the first inclined surface, so that the elastic portion is hidden in the second housing. The second abutting portion is also disengaged from the third abutting portion and the fourth abutting portion of the moving member and concealed in the second housing, and the moving member is no longer limited to the control member. Restrictingly displaceable on the first box body and the second box body, the first elastic element, that is, the elastic return position, displaces the moving member to the right, so that the third abutting portion abuts against the first abutting portion The first box body and the second box body are closed and fastened by the moving member, and the first box body can be automatically fastened as long as it abuts against the second box body 20, and the buckle is not fastened. The moving piece needs to be displaced by hand. The tool box of the present invention is slidably disposed on the first box body by the moving member, and the moving member is displaced on the first box body to engage the second box body with the moving member. The first box body and the second box system are securely fastened without being easily disengaged by the moving piece. The second restriction portion is compatible with the first restriction portion, The first restricting portion is displaceable within the second restricting portion, so that the moving member is prevented from coming off the first sliding rail when the elastic member is rebounded, so that the moving member does not overlap with the first box. The body is disengaged.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention.
