Detailed Description
The invention is further illustrated with reference to the following figures and examples:
a three-dimensional schematic diagram of a triple-shackle hoop locking mechanism with redundant design of the present invention is shown in fig. 1, and the detailed description of the embodiments will be given below with reference to fig. 2, 3, and 4.
The invention discloses a three-lock hoop locking mechanism with a redundant design, which has an overall structure shown in figure 2 and comprises a lock catch A1, a lock catch B2, a lock catch C3, a connecting piece A4, a connecting piece B5, a connecting piece C6, a pin shaft A7, a pin shaft B8, a pin shaft C9, a pin shaft D10, a first hoop shell 11 and a second hoop shell 12; the relative positions of the lock catch 1A, the lock catch 2B and the lock catch 3C are distributed in a triangular shape: the A lock catch 1 is connected to the B pin shaft 8, the B lock catch 2 is connected to the C pin shaft 9, and the C lock catch 3 is connected to the B pin shaft 8; the pin shaft A7 and the pin shaft B8 are fixed on a first clamp shell 11, and the pin shaft C9 and the pin shaft D10 are fixed on a second clamp shell 12; the relative positions of the connecting sheet A4, the connecting sheet B5 and the connecting sheet C6 are distributed in a triangular shape and correspond to the positions of the lock catch A1, the lock catch B2 and the lock catch C3; holes at two ends of the connecting sheet A4 are respectively fixed on the pin shaft A7 and the pin shaft B8 and are connected together, holes at two ends of the connecting sheet B5 are respectively fixed on the pin shaft C9 and the pin shaft D10 and are connected together, holes at two ends of the connecting sheet C6 are respectively fixed on the pin shaft C9 and the pin shaft D10 and are connected together;
referring to the schematic diagram of the position relationship and the fixing mode of the pin shaft and the connecting piece, as shown in fig. 3, one end of each of the two ends of the pin shaft a 7 to the pin shaft D10 is a boss, and the other end is an inner hole. The boss is located with the clamp casing, and hole structure and clamp casing cooperation adopt the mode of turning over and riveting to be fixed with first clamp casing 11 and second clamp casing 12.
As shown in fig. 3, the a link 4 connects the a pin 7 and the B pin 8 together. The pin shaft A7 and the pin shaft B8 have the same structure, and the center of the pin shaft A is a reducing thin shaft (shown as 701 in figure 3). Similarly, the B connecting plate 5 and the C connecting plate 6 work together to connect the C pin 9 and the D pin 10 together. The C pin shaft 9 and the D pin shaft 10 are identical in structure, and the two sides of the C pin shaft are of thin shaft reducing structures (101 and 102 in fig. 3). Two holes of the connecting sheet are respectively matched with the diameter-variable thin shafts of the two pin shafts on the same side and are fixed at the diameter-variable thin shafts of the pin shafts in a forced deformation mode.
As shown in fig. 3, the relative positions of the three connecting pieces on the pin are distributed in a triangular shape and correspond to the positions of the latches. The central plane of the connecting sheet is coplanar with the central planes of the three lock catches at the corresponding positions. The width dimension of the connecting piece is slightly smaller than the inner groove of the lock catch, and when the lock catch is locked, the inner groove of the lock catch can wrap the connecting piece without interfering with each other (see figure 4). After the lock catch is locked in place, the connecting sheet is hidden in the inner groove of the lock catch and is not exposed, and meanwhile, the connecting sheet is matched with the inner wall of the lock catch, so that the axial position of the lock catch can be limited, and the central position of the lock catch is prevented from deflecting.
When locked, the first and second clip housings 11, 12 close towards the center. The A lock catch 1 and the C lock catch 3 on the first hoop housing 11 slide forward along the central plane of the B connecting piece 5 and the C connecting piece 6 respectively and are matched and locked with the C pin shaft 9 on the second hoop housing 12. The B lock catch 2 on the second clip shell 12 slides forward along the central face of the a connecting piece 4 and is locked in cooperation with the B pin 8 on the first clip shell 11. The three lock catches are simultaneously locked on the pin shaft under the action of the torsion spring. After the three lock catches are completely locked, the auxiliary lock catch 13 is locked, and a square groove (shown as 131 in fig. 4) is designed in the center of the root part of the auxiliary lock catch to avoid interference with the end part of the B lock catch 2.
According to the three-lock-catch hoop locking mechanism with the redundancy design, the connecting pieces are connected with the adjacent pin shafts, and when one pin shaft fails, the other pin shaft can continue to work under the action of the connecting pieces. In the locking process, the three lock catches are simultaneously locked on the pin shaft under the action of the torsion spring. The locking of the hoop component is realized by adopting the three lock catches, the redundant protection structure is provided, and the reliability of the locking structure can be better improved.
