Specifically, in the present embodiment, the sliding connector 534 includes sliding plates 341 disposed at uniform intervals, and the sliding plates 341 are capable of sliding within the inner cavity of the fixed assembly 54; when the sliding plate 341 slides to the first preset position, the sliding plate is clamped with the internal structure of the fixed assembly 54 to be in a fixed state; when the sliding plate 341 slides to the second preset position, the locking state with the internal structure of the fixing assembly 54 is released.
As a preferred embodiment, the securing assembly 54 includes a securing sleeve 541 and a catch 542;
the fixed sleeve 541 is fixedly arranged on the shell of the bus IO main module 21 and each bus IO sub-module 22 and is coaxially arranged with the rotating component 53;
the fastening piece 542 is disposed on the inner surface of the fixing sleeve 541, and the fastening piece 542 is configured to cooperate with the sliding piece 534 to make the rotating component 53 in a fixed state or an unlocked state.
Specifically, in the present embodiment, the fastening members 542 include fastening plates 421 disposed at uniform intervals, and a fastening slot 422 is formed between each two fastening plates 421, and the fastening slot 422 is used to accommodate the sliding plate 341 in the sliding member 534 in the initial state; the end portion of each clamping plate 421 extends downwards to form a first clamping tooth 423 and a second clamping tooth 424, and a clamping position between the first clamping tooth 423 and the second clamping tooth 424 is used for clamping the sliding plate 341 in the sliding connection piece 534 when the sliding plate 341 rotates to a first preset position, so that the end portion of the rotating assembly 53 is in a fixed state.
Specifically, in the present embodiment, the number of teeth of the first tooth member 523 and the second tooth member 531 is the same, and the teeth of the first tooth member 523 and the second tooth member 531 face each other, and the teeth of the first tooth member 523 abut against the tooth surface portions of the teeth of the second tooth member 531. When the first tooth member 523 slides toward the second tooth member 531, the first tooth member 523 gradually engages with the second tooth member 531, and the rotation member 53 in which the second tooth member 531 is located rotates about the axis of the fixed sleeve 21.
Referring to fig. 8, fig. 8 is a schematic diagram illustrating an end ejection mechanism of an ejection sub-mechanism according to the present application.
Specifically, the principle of end ejection of the ejection sub-mechanism 5 is as follows:
in the initial state, the slide plate 341 in the slide contact 534 is positioned in the slide groove 422 as shown in fig. 8 (b), and the teeth of the first tooth profile 523 and the second tooth profile 531 are not engaged with each other, and the tooth surface portion is abutted with each other as shown in fig. 8 (a).
When the end of the ejecting sub-mechanism 5, that is, the end of the rotating member 533 in the rotating assembly 53 needs to be ejected, the user presses the dust-proof baffle B, and since one end of the dust-proof baffle B abuts against the clamping structure 521, the clamping structure 521 is fixedly connected with the first tooth-shaped member 523, the pressing of the dust-proof baffle B generates a downward component force to make each tooth in the first tooth-shaped member 523 and the second tooth-shaped member 531 abut against each other, and at this time, the first tooth-shaped member 523 slides along the x1 direction in fig. 7, the second tooth-shaped member 531 rotates downward along the x2 direction in fig. 7 relative to the first tooth-shaped member 523, and the spring member 532 is compressed.
During the downward movement of the second tooth profile 531, the sliding plate 341 in the sliding connection piece 534 gradually slides out of the sliding groove 422, and the inclined surfaces of the first tooth profile 523 and the second tooth profile 531 abut against and guide until the teeth on the first tooth profile 523 and the second tooth profile 531 are completely engaged. At this time, the sliding plate 341 is located below the first latch 423 and is in a partially engaged state, as shown in fig. 8 (c).
The user releases the hand to stop pressing the dust-proof baffle B, the spring 532 generates an upward resilience force, and since the inclined plane of the sliding plate 341 and the inclined plane of each latch have the same inclination, the sliding plate 341 continues to move upwards along the inclined plane of the first latch 423 to form a complete clamping state, as shown in fig. 8 (d), and the sliding plate 341 continues to drive the second tooth 531 to rotate relative to the first tooth 523 during the moving upwards process, so that the first tooth 523 and the second tooth 531 are separated from the engaging state, and return to the initial state. When the first tooth member 523 and the second tooth member 531 return to the initial state, the sliding plate 341 is already fully engaged with the inclined surface of each latch, so that the second tooth member 531 does not continue to rotate. At this time, the second tooth 531 is fixed, and the end portion of the second tooth 531 extends out of the housing and is fastened to the mounting groove 4 of the mounting base.
Referring to fig. 9, fig. 9 is a schematic diagram of an end rebound principle of an ejector mechanism according to the present application.
Specifically, the principle of end rebound of the ejector sub-mechanism 5 is as follows:
in the initial state, the slide plate 341 of the slide connector 534 is completely engaged with the inclined surface of each latch as shown in fig. 9 (b), and the teeth of the first tooth-shaped member 523 and the second tooth-shaped member 531 are not engaged with each other, and the tooth surface portions are abutted with each other as shown in fig. 9 (a).
When the end of the pop-up sub-mechanism 5, that is, the end of the rotating member 533 in the rotating assembly 53 needs to be rebounded, the user manually presses the dust-proof baffle B again, and since one end of the dust-proof baffle B abuts against the clamping structure 521, the clamping structure 521 is fixedly connected with the first tooth profile 523, and the pressing of the dust-proof baffle B generates a downward component force to make each tooth in the first tooth profile 523 and the second tooth profile 531 abut against each other, at this time, the first tooth profile 523 slides along the x1 direction in fig. 7, the second tooth profile 531 rotates downward along the x2 direction in fig. 7 relative to the first tooth profile 523, and the spring member 532 is compressed.
During the downward movement of the second tooth profile 531, the sliding plate 341 in the sliding connection piece 534 gradually slides out of each latch, and the inclined surfaces of the first tooth profile 523 and the second tooth profile 531 support and guide until the teeth on the first tooth profile 523 and the second tooth profile 531 are completely engaged. At this time, the slide plate 341 is under the first latch 423 in a partially slid-out state as shown in fig. 9 (c).
The user releases his/her hand to stop pressing the dust guard B, and the spring member 532 generates upward resilience, and since the inclined surface of the slide plate 341 has the same inclination as that of each latch, the slide plate 341 continues to move upward along the inclined surface of the second latch 424 to form a completely slid-out state, as shown in fig. 9 (d).
The sliding plate 341 moves up to push the rotating component 53 to move upwards, so that the inclined plane of the sliding plate 341 abuts against the inclined tooth surface of the second latch 424, and the second tooth 531 continues to rotate along the arrow x2 direction shown in fig. 7 due to the cooperation of the inclined plane of the sliding plate 341 and the inclined tooth surface of the second latch 424. At this time, as shown in fig. 9, the slide 341 slides into the next slide slot 422, and the rotating assembly 53 pushes the dust guard part out.
The sliding plate 341 continuously drives the second tooth-shaped piece 531 to rotate in the sliding process, so that the first tooth-shaped piece 523 and the second tooth-shaped piece 531 are separated from the fit state and return to the initial state. Since the sliding plate 341 is already in the sliding slot 422 again when the first tooth 523 and the second tooth 531 return to the initial state, the second tooth 531 does not rotate any further. At this time, the second tooth 531 is again in a fixed state, and the end of the second tooth 531 is retracted to be disengaged from the fastening with the mounting groove 4 of the mounting base 1.
After the above-mentioned manner is circularly adopted, the second tooth-shaped member 531 continuously rotates along the arrow x2 direction in fig. 4, so that the sliding plate 341 and the fastening member 542 are alternately located in the clamping position or the unlocking position, and the end portion of the ejecting sub-mechanism 5 is driven to present an ejecting or rebound state.
It will be appreciated that in this embodiment. Compared with the shell of the main bus IO module and each sub bus IO module, the dustproof baffle B is always in an ejected state as shown in fig. 1, so as to play a dustproof role, but when a user presses the dustproof baffle B, the part of the dustproof baffle B located in the shell is retracted or ejected due to the pressing action of the user.
Specifically, in the present embodiment, the number of the sliding plates 341 is plural, and the number of the sliding plates 341 is equal to the number of the sliding grooves 422.
