It connecing, and rotation can be shunk with the first push rod 3 and rotated, 4 other side of the first lock arm is connect with switching mechanism bottom plate 7, and
It can be rotated relative to switching mechanism bottom plate 7；Second lock arm, 4 ' side and the second push rod 3 ' hingedly, and can be pushed away with second
Bar 3 ' is sent to shrink rotation and rotate, the 4 ' other side of the second lock arm is connect with switching mechanism bottom plate 7, and can be relative to opening/closing machine
Structure bottom plate 7 rotates；Two lock arms (4,4 ') can withstand on switching mechanism closed position limited block when switching mechanism locks
Place；
Limit element 5, limit element 5 are connect with switching mechanism bottom plate 7, and can be locked when switching mechanism is locked to two
Fixed arm (4,4 ') is limited.
Wherein, when the first push rod 3 and rotary shaft 1 are located at same straight line and the second push rod 3 ' and rotary shaft 1
When same straight line, which is in dead-centre position, at dead-centre position, two push rod (3,3 ') compresses in length
To shortest length, and after crossing dead-centre position, i.e., crossed respectively in the first push rod 3 and the second push rod 3 ' respectively above-mentioned straight
When line, which reaches latched position.
To realize the reliable limit to two lock arms (4,4 '), limit element 5 includes the first caging bolt 51 and second
Caging bolt 52, the first caging bolt 51 and the second caging bolt 52 are both secured to switching mechanism bottom plate 7, the first caging bolt 51
Two lock arms (4,4 ') are respectively facing with the nut side of the second caging bolt 52, when switching mechanism locking, the first limit spiral shell
The nut side of bolt 51 and the second caging bolt 52 withstands on two lock arm (4,4 ') sides respectively, to two lock arms (4,4 ') into
Row limit.
The rotary shaft 1 of front self-locking device is used to carry out stress rotation in two rotating arm (2,2 ') stress.To realize
12 two kinds of structures of single main shaft 11 and double main shafts can be used in above-mentioned function, rotary shaft 1.When using single 11 structure of main shaft, referring to fig. 4,
Single main shaft 11 and two rotating arms (2,2 ') connect simultaneously, two rotating arms (2,2 ') simultaneously with the common rotation of single main shaft 11 and
Rotation.When using double main shafts 12, referring to FIG. 1 to FIG. 3, double main shafts 12 include the first main shaft 121 and the second main shaft 122, and first is main
Axis 121 and the second main shaft 122 are separately connected with first rotating arm 2 and the second rotating arm 2 ', first rotating arm 2 and the second rotating arm
2 ' rotate with the first main shaft 121 and the second main shaft 122 respectively and are rotated.
With continued reference to FIG. 1 to FIG. 4, rotating arm is connect simultaneously with rotary shaft 1, push rod and 6 three of driving element, two rotations
Pivoted arm (2,2 ') structure is identical, includes the first articulated section 21, the second articulated section 22 and third articulated section 23, and rotating arm passes through the
One articulated section 21 and driving element 6 are hinged, and drive rotating arm movement by driving element 6；Rotating arm passes through the second articulated section 22
With rotation axis connection, and rotating arm can with rotary shaft 1 rotate and rotate；Rotating arm is cut with scissors by third articulated section 23 and push rod
It connects, and in two rotating arm (2,2 ') pivotings, two push rod (3,3 ') can be driven to shrink rotation.
Push rod uses elastic rod, it is preferred to use and elastomeric spring body structure, elastomeric spring body structure can be compressed in stress,
And when stress mitigates, certain elastic force is maintained.First push rod 3 and 3 ' structure of the second push rod and the complete phase of working principle
Together, its course of work is described by taking the first push rod 3 as an example below:
Referring to Fig. 5, in the unlocked state, the first push rod 3 does not stress, and length keeps former long.When driving element 6 drives
When first rotating arm 2 is rotated with rotary shaft 1, the first push rod 3 is pressurized and rotates, and when the first push rod 3 and rotary shaft 1 are located at
When same straight line, which reaches dead-centre position, and the first push rod 3 is pressurized at this time and its length reaches most short.Ginseng
See that Fig. 2, the front self-locking device of Fig. 2 are in self-locking state, when driving element 6 drives first rotating arm 2 to continue around 1 turn of rotary shaft
When dynamic, which crosses dead-centre position, and the first push rod 3, which is pressurized, to be mitigated, 3 length elongation of the first push rod, at this point,
First lock arm, 4 side is withstood at the first caging bolt 51, and 4 other side of the first lock arm withstands on the limit of switching mechanism closed position
At block, reach self-locking position.Even if driving element 6 does not work at this time, since the maintenance of the first push rod 3 has certain elastic force, pass through
The elastic force of first push rod 3 can keep 4 present position of the first lock arm, i.e., not will lead to the first lock arm 4 and retract, further
Ensure that the first lock arm 4 is withstood on always at the limited block of switching mechanism closed position, it is ensured that switching mechanism moves pivoted arm or pod
Hatch door is tightly closed, and realizes the self-locking of the front self-locking device.
With continued reference to Fig. 1~2, Fig. 4~5, driving element 6 preferably uses cylinder, and cylinder side and switching mechanism bottom plate 7 connect
