Description

Toolbox waterproof construction

The present invention relates to a waterproof structure of a toolbox, which mainly provides a groove formed by an inner mold, and can improve the waterproof stability of the tool case and prevent the gasket from falling off.

The toolbox is mainly for arranging various tools to be stored or carried out. However, when the outdoor two or indoor tidal temperatures cause the outside water to penetrate into the toolbox, the metal tool of the toolbox is prone to rust damage. Missing.

In order to improve the foregoing situation, the present invention has a soft gasket design disposed at a position relative to the casing of the tool box, so that the hard casing can press the gasket to have a waterproof sealing effect when the two casings are closed, but the two casings are often closed. The displacement of the gasket is caused by poor waterproofing or even loss of the water, and the gasket is only prone to the lack of water seepage gap by pressing the two casing planes.

The purpose of this creation is to provide a structure that improves the waterproof stability of the tool case and prevents the gasket from falling off.

The present invention comprises a hard-working first and second casings and a soft gasket, and the first and second casings are pivotally connected to each other, and the fastening portions are arranged on the other side, and are respectively opposite to each other. a second circumference, and having a first plane portion below the first circumference and an annular flange downwardly disposed on the first plane portion; a second plane portion above the second circumference and a second plane portion corresponding to the first circumference The flange position of the flange is formed by the inner mold forming the annular groove, and the bottom surface of the groove is downwardly disposed with the insertion groove having a width smaller than the bottom surface of the groove, and the inwardly protruding buckle edge is formed at the top end of the insertion groove; Positioning at the bottom of the second casing, and the bottom end is provided with an engaging portion that can be tightly fitted into the engaging groove and clamped by the buckle edge, and the engaging portion has a close portion that can be accommodated in the groove position, and The two sides of the abutting portion have convex portions protruding from the top end of the groove, and the central portion is provided with a concave portion corresponding to the flange position of the first casing.

Therefore, the first and second casing covers are combined to make the flange of the first casing resist the concave portion of the gasket when the fastening portion is fastened, and the two sides of the gasket are outwardly expanded and the second portion The sidewall of the housing groove is more tightly and tightly coupled with the water-proof joint, and the first plane can press the convex portion of the gasket to deform the convex portion and seal the gap between the first and second plane portions to have good waterproof effect, and the creation The gasket is engaged by the lower engaging portion and the engaging groove of the second casing and is engaged by the buckle edge, and the two sides of the gasket are tightly pressed with the groove sidewall, so that the gasket is tightly coupled with the second casing The degree is far greater than the engagement between the flange of the first housing and the recess of the washer, so that when the first housing is opened, the washer can still be stably assembled on the second housing without falling off for better operational stability.

Please refer to the first to fourth figures. The present invention includes a rigid first and second housings 1, 2 and a soft gasket 3, and the first and second housings 1 and 2 are pivotally connected to each other. The other side is provided with the fastening portions 10, 20, and has opposite first and second peripheral edges 11, 21, respectively, and has a first planar portion 12 below the first peripheral edge 11 and a downwardly disposed ring at the first planar portion 12. a second flange portion 22; and a second flat portion 22 having a second flat portion 22 thereon, and the second flat portion 22 corresponding to the flange 13 of the first peripheral edge 11 is formed by an inner molding annular groove 23, and the groove 23 The engaging groove 24 having a width smaller than the bottom surface of the groove 23 is disposed downward from the bottom surface, and the inwardly projecting buckle edge 25 is formed at the top end of the engaging groove 24.

The gasket 3 is disposed at the position of the recess 23 of the second casing, and the bottom end is provided with an engaging portion 31 which can be closely fitted into the engaging groove 24 and clamped by the buckle edge 25, and the upper portion of the engaging portion 31 can be accommodated in the concave portion. The abutting portion 32 at the position of the groove 23 has a convex portion 33 protruding from the top end of the groove 23 on both sides of the groove portion 32, and a concave portion 34 is disposed at a position corresponding to the flange 13 of the first casing.

Referring to the fifth and sixth figures, the first and second housings 1 and 2 are combined to make the flanges 13 of the first housing 2 press against the recesses 34 of the washer 3 when the fastening portions 10 and 20 are engaged. The two sides of the sealing portion 32 of the gasket 3 are outwardly expanded to be more tightly and tightly coupled with the side wall of the groove 23 of the second casing 2, and the first flat portion 12 can press the convex portion 33 of the gasket 3 to make the convex portion 33 can deform and seal the gap between the first and second flat portions 12, 22 to have good waterproof effect.

The gasket 3 of the present invention is engaged with the engaging groove 24 of the second casing 2 by the lower fitting portion 31 and is engaged by the buckle edge 25, and the two sides of the abutting portion 32 of the gasket 3 are pressed against the side wall of the groove 23, thereby The engagement tension between the washer 3 and the second housing 2 is much greater than the engagement between the flange 13 of the first housing 1 and the recess 34 of the washer 3, so that the washer 3 can be stably assembled when the first housing 1 is opened. The second housing 2 has better operational stability.

Therefore, according to the above, the present invention can have better waterproofness and prevent the gasket from falling off the second casing when the first casing is opened, and the foregoing embodiment is an example of the creation, which is not a limitation of the creation, and is based on the spirit of the creation. The equivalent change should also fall within the scope of this creation.
