Referring to fig. 7, in the present embodiment, the first pull rod 71 and the second pull rod 75 are connected by a linkage pull rod 70. That is, one end of the link lever 70 is connected to the first lever 71, and the other end is connected to the second lever 75. The first pull rod 71 is connected to the second swing arm 240 through a ball bearing, and the ball bearing also connects the first pull rod 71 to the linkage pull rod 70. The arrangement is that the first pull rod 71, the second swing arm 240 and the linkage pull rod 70 adopt the same ball bearing, so that mutual linkage can be realized, and the structure is more compact. Similarly, the second pull rod 75, the linkage pull rod 70 and the second swing arm 240 in the second lock case assembly 50 are also connected through a ball bearing, so as to realize mutual linkage.
The first handle assembly 10 rotates, the first lock shell assembly 20 and the linkage pull rod 70 are driven to move through the first pull rod 71, and the first lock shell assembly 20 moves to separate the first lock seat assembly 30 from the first lock shell assembly 20, so that unlocking is realized. Meanwhile, the linkage pull rod 70 drives the second pull rod 75 to move, the second pull rod 75 drives the second lock case component 50 to move, and the second lock case component 50 moves to separate the second lock base component 60 from the second lock case component 50, so that unlocking is realized. Similarly, the second handle assembly 40 is rotated to move the second lock housing assembly 50 and the linkage rod 70 via the second pull rod 75, and the second lock housing assembly 50 is moved to separate the second lock housing assembly 60 from the second lock housing assembly 50, thereby unlocking the lock. Meanwhile, the linkage pull rod 70 drives the first pull rod 71 to move, the first pull rod 71 drives the first lock shell assembly 20 to move, and the first lock shell assembly 20 moves to separate the first lock seat assembly 30 from the first lock shell assembly 20, so that unlocking is realized. No matter which end of the fairing 100 the operator is located, the operator can operate the first handle assembly 10 or the second handle assembly 40 to open and close the fairing 100, the operation is convenient, and the operation safety is high.
The specific working principle of the double-handle lock structure and the fairing 100 provided by the embodiment is as follows:
referring to fig. 8 and 9 in conjunction with fig. 7, the first handle assembly 10 is illustrated in operation when the fairing 100 is opened, i.e., the hood 101 and door 103 of the fairing 100 are from locked to open. An operator pulls the handle 110 on the outer side of the cover 101, the handle 110 rotates clockwise around the first rotating shaft 121 to drive the two first rotating arms 120 to rotate clockwise, the connecting rod 130 connected between the two first rotating arms 120 overcomes the action of the first elastic element 141 and moves towards the direction close to the first pull rod 71 (leftwards in the figure), the connecting rod 130 moves leftwards to drive the moving rod 140 to move leftwards, the moving rod 140 pushes the connecting head 160 to move leftwards to enable the first swing arm 170 to rotate anticlockwise, the first swing arm 170 drives the first pull rod 71 to move leftwards to enable the second swing arm 240 to rotate clockwise, namely the second swing arm 240 drives the lock pin 230 to exit the locking space 215, and the lock pin 230 moves rightwards. The stopper 221 in the locking space 215 is moved toward the locking bar 320 by the third elastic member 225 to withdraw the locking bar 320 from the locking space 215. In this state, the stopper 221 is positioned in the locking space 215 to block the first through hole and the second through hole, so that the lock pin 230 cannot be inserted into the locking space 215.
While the first swing arm 170 drives the first pull rod 71 to move leftward, the first pull rod 71 also drives the linkage pull rod 70 to move leftward, the linkage pull rod 70 drives the second swing arm 240 in the second lock case assembly 50 to rotate clockwise, so that the lock pin 230 in the second lock case assembly 50 exits the locking space 215, and the lock pin 230 in the second lock case assembly 50 is separated from the lock rod 320, that is, the first lock case assembly 20 is separated from the first lock holder assembly 30, and the second lock case assembly 50 is separated from the second lock holder assembly 60, so as to open the cover body 101 and the cover door 103 of the fairing 100. The movement and the moving away of the handle 110 of the second handle assembly 40 are similar to the above-mentioned case, and will not be described again.
When the cowl 100 is closed, the cover body 101 and the cover door 103 of the cowl 100 are switched from the open state to the closed state. An operator only needs to apply external force to the cover door 103, so that the first lock holder assembly 30 and the second lock holder assembly 60 on the cover door 103 are inserted into the locking space 215, that is, under the action of the external force, the lock rod 320 of the first lock holder assembly 30 directly impacts the stopper 221 in the first lock shell assembly 20, so that the third elastic member 225 deforms, the lock rod 320 extends into the locking space 215 of the first lock shell assembly 20, the second swing arm 240 rotates in the counterclockwise direction under the action of the elastic force of the second elastic member 243, drives the lock pin 230 to extend into the locking space 215, and sequentially passes through the first through hole, the lock hole and the second through hole, so that the lock rod 320 is fixed in the locking space 215.
Similarly, the lock rod 320 of the second lock housing assembly 60 directly hits the stopper 221 in the second lock housing assembly 50, so that the third elastic member 225 deforms, the lock rod 320 extends into the locking space 215 of the second lock housing assembly 50, and the second swing arm 240 rotates counterclockwise under the elastic force of the second elastic member 243 to drive the lock pin 230 to extend into the locking space 215, and sequentially passes through the first through hole, the lock hole and the second through hole, so as to fix the lock rod 320 in the locking space 215. Namely, the first lock housing assembly 30 and the first lock housing assembly 20, and the second lock housing assembly 60 and the second lock housing assembly 50, to close the cowl body 101 and the cowl door 103 of the cowl 100.
