Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the above.
The mechanical quick locking and unlocking mechanism shown in fig. 1 and 2 comprises a support upright 1; two support columns 1 are vertically arranged at two ends of a horizontal tray 5, a driving rod 7 is fixed at the bottom of the tray 5, a locking block 4 is arranged at the position, close to the end, of the inner side of the support column 1, the locking block 4 and the support column 1 are elastically fixed, the front end of the locking block 4 is provided with a convex part, the surface, facing the end of the support column 1, of the convex part is a plane, the surface, facing away from the end of the support column 1, of the convex part is an inclined plane, the driving rod 7 is provided with an inclined plane at the position corresponding to the locking block 4, and the end of the tray 5 downwards extends through the driving rod 7 and is in plane contact with the convex part at the inner end of the locking block 4.
A waist-shaped groove is formed at the joint between the tray 5 and the driving rod 7, so that the tray 5 can move up and down relative to the driving rod 7.
The locking blocks 4 are symmetrically arranged left and right.
The locking blocks 4 are symmetrically arranged up and down.
The number of the locking blocks 4 is four.
The rear end of the locking block 4 is connected to the supporting upright 1 through a bolt 2, and a spring 3 is sleeved on the bolt 2.
The upper end edge of the driving rod 7 is provided with an upward protruding structure, and the upward protruding structure limits the position of the tray 5 on the horizontal plane.
The driving rod 7 has a symmetrical upper and lower structure.
Thus, the power source of the present invention does not directly act on the tray 5, but drives the tray 5 through the driving lever 7.
The whole structure is bilaterally symmetrical, and when the starting positions are required to be locked, four locking blocks 4 are distributed in a square shape; when only one position is needed for locking, two locking blocks 4 are shared, and the locking blocks are symmetrical left and right.
Functional characteristics: when locking and unlocking, the unlocking speed can be automatically matched with the movement speed. The higher the running speed, the greater the unlocking speed. When the speed in the moving direction reaches 0.1m/s, the locking and unlocking time can reach within 0.1 s. The locking load is determined by the upright post and the locking block, and the limit load of the movement device is the maximum locking load of the mechanism in theory. The locking precision is determined by the matching precision of the locking block and the supporting upright post, under the condition that the locking block can work normally, the common matching of the hole shaft is referred, H8/H7 is used for heavy load, H7/H6 is used for medium load and below, and the positioning precision can be within 5 wires.
The working process comprises the following steps: first, the power source switches the motion through the driving rod 7. When the driving rod 7 moves, the stroke is divided into two parts. The former part is unlocking movement, when the tray 5 is connected with the driving rod 7, a waist-shaped groove is used for connection, when the driving rod 7 moves, an idle stroke is provided, and unlocking is completed during the idle stroke movement. The latter part is effective movement, and when the driving rod 7 runs in the kidney-shaped groove in a free stroke, the driving tray 5 integrally completes movement.
Working principle: the locking and unlocking are precise combination of a plane and an inclined plane, wherein the plane ensures reliable locking and cannot loosen along with the weight change of a locked object; the inclined plane is used as an unlocking surface, under the combined action of spring force and inclined plane friction force, the fact that the gravity of the driving rod 7 cannot unlock is guaranteed, and after the power of the power source is added, the spring 3 can be driven to unlock.
During locking, as shown in fig. 2, one end of the driving rod 7 is designed with an inclined plane and is combined with the inclined plane of the locking block, at this time, the driving rod 7 is attached to the upper end surface of the kidney-shaped groove of the tray 5 under the action of spring force, and the plane on the locking block 4 locks the tray 5. After the tray 5 is in place, the spring 3 ejects the locking block 4 to lock.
During unlocking, the power source drives the driving rod 7 to move downwards, at the moment, through the cooperation of the unlocking plane, the driving rod 7 drives the locking block 4 to compress the spring 3 through the inclined plane, and the locking plane slides relatively, so that unlocking action is completed. After unlocking is completed. The driving rod 7 is contacted with the lower bottom surface of the kidney-shaped groove on the tray 5 to drive the tray to move.
When the movement direction is other directions, the locking and unlocking principles are consistent. At this time, only the power source needs to be changed to accommodate the upward or downward power change, or the leftward or rightward friction change.
