Detailed Description

The technical features and advantages of the present invention will be explained in more detail below with reference to the accompanying drawings in conjunction with the embodiments.

As shown in fig. 1-7, the lock catch of the lever type glove box comprises a long bolt 13 and a short bolt 14 which are arranged in parallel, wherein the long bolt 13 and the short bolt 14 are connected through a connecting mechanism, the connecting mechanism comprises a fixed seat 7, two sides of the fixed seat 7 are respectively provided with a swing rod 2 and a lever 9, two ends of the swing rod 2 are respectively connected with the long bolt 13 and the short bolt 14, a ball head 5 on the swing rod 2 is accommodated in a limit groove 11 of the lever 9, which is equivalent to sliding hinging, so that no impact action and abnormal sound of the lever 9 and the swing rod 2 can be ensured, and the limit groove 11 penetrates through a cavity arranged on the fixed seat 7.

Further, a second torsion spring 1 is installed between the swing rod 2 and the fixed seat 7, a first torsion spring 8 is installed between the deflector rod 9 and the fixed seat 7, and the torque of the second torsion spring 1 is larger than that of the second torsion spring 1, so that the swing rod 2 and the deflector rod 9 are in a joint linkage state. Because the first torsion spring 8 makes the deflector rod 9 bear unidirectional rotation moment, the second torsion spring 1 makes the swing rod 2 bear unidirectional rotation moment, when the torsion of the second torsion spring 1 is greater than the torsion of the first torsion spring 8, the deflector rod 9 and the swing rod 2 can be always in the attached mutual linkage action, and adverse phenomena such as impact and dislocation can be avoided when the deflector rod 9 is operated.

Further, the swing rod 2 is in snap connection with the clamping cylinder 6 on the fixed seat 7, the end part of the second torsion spring 1 is respectively connected with the swing rod 2 and the clamping cylinder 6 on the fixed seat 7, the end part of the first torsion spring 8 is respectively connected with the deflector rod 9 and the extending pin 12 on the fixed seat 7, the extending pin 12 is in matched connection with the rotating shaft hole 10 on the deflector rod 9, and the rotating shaft holes 10 are symmetrically arranged on the deflector rod 9.

Further, two sides of the swing rod 2 are respectively provided with a first bulge 3 and a second bulge 4, the first bulge 3 is connected with a short bolt 14, and the second bulge 4 is connected with a long bolt 13.

When the switch is operated, the deflector rod 9 is stirred, the limit groove 11 rotates along with the deflector rod 9, the ball head 5 is driven to rotate, the swing rod 2 is driven to rotate, the long bolt 13 and the short bolt 14 are further driven to perform linear motion, the long bolt 14 and the short bolt 14 finish translational bolt insertion operation, as the arrow mark in fig. 1 is in the direction of linear motion, and when no external force is applied to the deflector rod 9, the torsion force of the second torsion spring 1 drives the long bolt 13 and the short bolt 14 to reset to the original positions.

In summary, the ball head 5 of the swing rod 2 and the inner surface of the limit groove 11 of the deflector rod 9 are always in a fitting state under the action of the double torsion springs, and the ball head 5 automatically corrects the angle difference between the swing rod 2 and the deflector rod 9 on the inner surface of the limit groove 11, so that the deflector rod 9 and the swing rod 2 have smooth mutual linkage effects when rotating on different surfaces.

In the device, the torsion spring, the bolt, the clamping piece and other parts are all of the prior art or materials, and the skilled person can directly purchase or order from the market according to the required product model and specification.
