Technical Field

The present invention relates to locks, and more particularly to locks for mounting on tool boxes.

Background

The tool box is a special case and is widely applied to protecting special tools, medical instruments, measuring instruments, anti-terrorist products, high-grade bicycles and the like; the company has applied for a lock-catch patent, but during the use process, we find that when the tool box is dropped from a high place, such as more than 1.2 meters, the lock of the tool box has a certain probability of being opened; because the toolbox is generally used outdoors and the devices inside are more precise or expensive, if the toolbox falls from a high place, the devices in the toolbox are easy to fall out of the toolbox, so that the devices are damaged.

Disclosure of Invention

Based on the problems, the invention provides the lock of the tool box, which is in two-stage linkage, so that the tool box can be unlocked by one hand, the simplicity of unlocking is improved, and meanwhile, when the tool box falls from a high place, the lock of the tool box cannot be opened, so that equipment in the tool box is protected.

The technical scheme adopted by the invention is as follows:

a lock of a tool box comprises a lock catch and a T-shaped block; the lock catch is matched with the T-shaped block;

the T-shaped block comprises a clamping strip and a fixing strip, and the fixing strip is fixed on one box body of the tool box; the clamping strip is fixed on the fixing strip;

the lock catch comprises a first connecting piece and a second connecting piece; one end of the first connecting piece is fixed on the other box body of the tool box through a first rotating shaft; the first connecting piece and the second connecting piece are connected through a second rotating shaft;

a lug is arranged on one side of the second connecting piece, grooves are formed in two sides of the lug, and the second rotating shaft penetrates through the first connecting piece and the lug to enable the other end of the first connecting piece to rotate in the groove; the other side of the second connecting piece is provided with a buckling block mounting seat; the buckling block mounting seat is fixedly provided with a buckling block through a third rotating shaft; a first spring seat is fixed on one side of the buckle block mounting seat, the first spring seat is circular, and a circular column is fixed in the middle of the first spring seat, so that a circular groove is formed in the first spring seat, and one side of the spring is clamped in the circular groove;

the buckling block is T-shaped and comprises a pressing block, a hook block and a balance weight; the pressing block, the hook block and the balance weight are integrally formed; the hook block is matched with the clamping strip in the T-shaped block; the balance weight is fixed below the hook block, a round hole is formed in the joint of the hook block and the balance weight, the third rotating shaft penetrates through the round hole, and the buckling block is fixed on the buckling block mounting seat so that the buckling block can rotate on the buckling block mounting seat;

a second spring seat is arranged at the back of the buckling block; the second spring seat is circular, and the middle is fixed with circular post, makes to form circular recess on the second spring seat, and the spring opposite side card is in circular recess.

Further, the first connecting piece is C-shaped.

Furthermore, the buckling block mounting seat is stepped, and a first reinforcing rib and a second reinforcing rib are fixed in the buckling block mounting seat; the first reinforcing rib is parallel to the second reinforcing rib

Further, the width of the first reinforcing rib is smaller than that of the second reinforcing rib.

Furthermore, the width of the first reinforcing rib is less than or equal to 5 mm.

Furthermore, the counterweight is obliquely fixed below the hook block and is rectangular.

Furthermore, a convex foot is fixed at one end of the counterweight.

Furthermore, a torsion spring is installed at one end of the second rotating shaft, one leg of the torsion spring is fixed at one side of the protruding block, and the other leg of the torsion spring is fixed at the inner side of the first connecting piece.

Furthermore, the clamping strip is rectangular.

Furthermore, a reinforcing rib is fixed in the first connecting piece, and the shape of the reinforcing rib is the same as that of the first connecting piece.

The lock of the tool box is simple in structure, and can be unlocked easily by one hand through the two-stage linkage of the first connecting piece and the second connecting piece; the first connecting piece and the second connecting piece are connected in a rotating mode through the rotating shaft, one end of the first connecting piece is connected with the box body, the buckling block on the second connecting piece is matched with the T-shaped block, the pressing block in the buckling block is pressed, the balance weight moves outwards, the hook block is separated from the clamping strip in the T-shaped block, the second connecting piece rotates through the second rotating shaft, the second connecting piece is separated from the box body of the tool box, and the box is opened. When the tool box is in a closed state, the counter weight in the buckle block is inward, and when the tool box falls from a high place, the pressing block can be separated from the clamping strip only by overcoming the force borne by the counter weight, so that the bearing capacity of the pressing block is enhanced, and meanwhile, due to the existence of the counter weight, the counter weight is obliquely fixed below the pressing block, so that when the tool box falls from a high place, particularly when the side of the box body lock directly falls to the ground, and is subjected to gravity and instantaneous inertia when the side of the box body lock is touched with the ground, the pressing block can be separated from the clamping strip only by overcoming the counter weight; therefore, when the lock of the tool box falls from high altitude, the lock can not be automatically opened, and the safety of all devices in the tool box is protected.
