The technical scheme of the invention is as follows: an electronic disk block unloading mechanism comprises a cover plate, a stop buckle, a torsion mechanism, a lever, a first rotating shaft, a second rotating shaft and a roller; the lower end of the cover plate is connected with the whole machine through a second rotating shaft, the upper position of the lower end of the cover plate is further connected with one end of the lever through a first rotating shaft, the torsion mechanism is nested with the first rotating shaft and can drive the lever to rotate along the first rotating shaft, the other end of the lever is provided with a roller, the assembling and disassembling end of the electronic disc is provided with a stop buckle, and the roller can roll in the stop buckle.

A stop block is arranged at the joint of the cover plate and the lever to limit the rotation angle of the lever relative to the cover plate.

The invention has the advantages and effects that: the mechanism provided by the invention is quick and labor-saving to disassemble, simple to install and high in reliability; the cover plate is opened and is rotated downwards, so that the lever is driven to rotate, and the electronic disk is pulled to move outwards until the electronic disk is completely separated from the whole machine; the installation is simple, insert the module and close the apron can, no loaded down with trivial details operation. The electronic disk is subjected to the action of pretightening force from the torsion spring after being installed, so that looseness can be effectively prevented, and the reliability is improved.

Detailed Description

According to the invention, the lever mechanism is integrated on the external cover plate of the electronic disk, the corresponding buckle stopping structure is added on the electronic disk, the full-automatic dismounting process from the opening of the cover plate is realized, and the pretightening force is applied to the electronic disk through the internal torsion spring mechanism after the electronic disk is mounted, so that the electronic disk is effectively prevented from loosening in the whole machine, and the specific implementation scheme is shown in fig. 2. An electronic disk block unloading mechanism comprises a cover plate (1), a stop buckle (5), a torsion spring (6), a lever (7), a first rotating shaft (8), a second rotating shaft (9), a third rotating shaft (10), a roller (11) and a stop block (12); the lower extreme of apron (1) links to each other with complete machine (3) through second pivot (9), apron (1) still links to each other with lever (7) one end through first pivot (8), torsional spring (6) are nested with first pivot (8), and on torsional spring (6) both ends were fixed in apron (1) and lever (7) respectively, the lever (7) other end passes through third pivot (10) and links to each other with gyro wheel (11), electronic disc (2) loading and unloading end is provided with ends and detains (5), and pass through the connector with the complete machine and link to each other, be provided with at apron (1) and lever (7) junction and end (12), in order to restrict the rotation angle of lever (7) for apron (1).

Under the natural state of the torsion spring (6), two extending ends form a specific included angle, so that after the torsion spring is fixedly installed with the cover plate (1) and the lever (7), a corresponding included angle is formed between the cover plate (1) and the lever (7).

The lever (7) is connected with the roller (11) through the third rotating shaft (10), so that the roller (11) can rotate freely through the third rotating shaft (10) to protect the contact surface of the electronic disk (2) and the lever (7) from being abraded and reduce the operation resistance.

The first rotating shaft, the second rotating shaft and the third rotating shaft are all bearings, so that the movement of the lever (7) can be realized, and the structure is simple.

The working principle of the electronic disk block unloading device provided by the invention can be seen in the attached figures 4-6: when the device is installed, the lower end of the cover plate (1) rotates upwards by taking the first rotating shaft (8) as an axis, and the upper end of the cover plate is fixed on the whole machine by a set screw; in the process that the cover plate (1) is tightly attached to the whole machine (3), the torsion spring (6) is compressed, so that the lever (7) and the roller (11) at the upper end are tightly attached to the end face of the electronic disk (2) to play a role in fixing the electronic disk (2), and after the electronic disk is fixed, the upper end of the cover plate (1) is locked by the locking mechanism.

When the electronic disc is opened, the locking mechanism is loosened, the upper end of the cover plate (1) is separated from the whole machine (3), in the separation process, the roller (11) on the lever (7) is pushed by the torsion spring (6) to roll downwards and cling to the end face of the electronic disc (2), and the electronic disc enters the stop buckle (5), when the lower end of the cover plate (1) rotates downwards by taking the first rotating shaft (8) as an axis, the torsion spring (6) is changed into an expansion state from compression and limited by the stop block (12), the upper end of the lever (7) is driven to move towards the cover plate (1), the electronic disc (2) is driven to be separated from the whole machine through the stop buckle (5), when the lower end of the cover plate (1) continues to rotate downwards by taking the first rotating shaft (8) as the axis, the upper end of the lever (7) and the roller (11) are separated from the stop buckle (5.
