In addition, the head and tail sections below the rail groove 11 are respectively formed with an avoiding groove 14, and the avoiding groove 14 mainly functions to provide an avoiding space for an exiting plate (not shown in the figures, which belongs to the prior art) of the extracting member 20.
Furthermore, a positioning tower 15 for installing the automatic locking mechanism 2 is protruded from a position of a locking hole 203 opened in a pair of sliding rails 202 of the pair of fixed rails 1 corresponding to the bottom of the drawer 20, and the positioning tower 15 has a through groove 151 communicated with the rail groove 11. In addition, in order to provide for the installation of the manual unlocking mechanism, a stop member 16, such as a housing and a support member 17, such as a raised rail, are provided at a spacing on one side of the positioning tower 15; wherein the support 17 is located between the positioning tower 15 and the stop 16.
The automatic locking mechanism 2 includes a fixing pin 21 sleeved in the through slot 151, a tenon 211 having a guiding surface 212 and capable of passing through the through slot 151 and extending into a rail slot 11 is disposed at the bottom of the fixing pin 21, a first corner tenon 213 is axially protruded above the tenon 211, and a pull handle 214 is disposed outside the through slot 151. At least one protruding rib 215 is protruded from each outer peripheral surface of the tenon 211 different from the guiding surface 212, and the protruding ribs 215 can increase the close contact degree with the through groove 151 to avoid the shaking.
Referring to fig. 5, 6 and 12 a-12 d, the guiding surface 212 is implemented as an inclined surface. In another embodiment, the guiding surface 212 is a circular arc surface.
The automatic locking mechanism 2 further includes an elastic body 22, in which the elastic body 22 is implemented as a torsion spring, a fixed end 221 of the torsion spring is inserted into a pin hole 152 of the positioning tower 15, and an engaging end 222 is inserted into a pin hole 216 of the fixing pin 21. Wherein the positioning tower 15 is laterally communicated with a spring chamber 153 for installing the elastic body, and a plurality of spring columns 154 for sleeving a plurality of rings 223 of the elastic body 22 are protruded in the spring chamber 153.
Further, the manual unlocking mechanism 3 includes a shaft 31 and a spring 32. As shown in fig. 13, the supporting member 17 is implemented as a T-shaped or inverted L-shaped rail, at least one side of the bottom of the shaft 31 is provided with at least one hook 311 capable of engaging with the supporting member 17, so that the shaft 31 can move axially on the supporting member 17, the spring 32 is disposed in the stopper 16, such as a housing chamber, and a shaft 312 at one end of the shaft 31 is sleeved with the spring 32, and a second tenon 313 at the other end of the shaft 31 passes through the positioning tower 15 and abuts against the first tenon 213.
As shown in fig. 12a, which shows a cross-sectional view of the automatic locking mechanism 2 attached to the positioning tower 15, the tenon 211 radially protrudes from the through-slot 151 by extending the elastic body 22, so that the guiding surface 212 faces the insertion direction of the rail slot 11.
Referring to fig. 8 and 9, the pair of fixing rails 1 are fixed on the first plate 101 of the host 10, such as a motherboard, at intervals to form the shape of the plate. The pair of fixed rails 1 are used for inserting and extracting the extracting member 20, such as a network card, and the first plate 101 is provided with a connector 102 at the end of the pair of fixed rails 1. The drawing member 20 has a second plate 201, such as a circuit board (shown in fig. 9), and a connection plug (not shown due to the projection angle relationship) is disposed at a position corresponding to the connector 102 inside the second plate 201.
Referring to fig. 12a to 12c, the pair of sliding rails 202 are inserted into the pair of rail grooves 11 of the pair of fixed rails 1, so that each sliding rail 202 slides inward along the corresponding rail groove 11, when the sliding rail 202 contacts the guiding surface 212 of the tenon 211, the tenon 211 is caused to move upward, the first tenon 213 is caused to move upward along the second tenon 313, and the engaging end 222 of the elastic body 22 and the spring 32 are compressed (shown in fig. 12a to 12 b). Then, the sliding rail 202 moves inward along the bottom corner of the locking tongue 211 until the engaging end 222 extends when the locking hole 203 moves below the locking tongue 211, so that the locking tongue 211 is locked into the locking hole 203, thereby forming an automatic locking function (shown in fig. 12 c). At this time, a plug (not shown) on the back of the drawing member 20 is plugged into the connector 102 to form an electrical connection, and the automatic locking mechanism 2 is locked in the locking hole 203, so that the drawing member 20 is not separated from the host 10 due to the vibration environment.
To unlock the drawer 20 and pull it out, the user holds the handle 214 with one hand and lifts it up to retract the latch 211 into the through slot 151, at which time the first latch 213 goes over the second latch 313 and forms an abutting locked configuration, and simultaneously compresses the engaging end 222 of the elastic body 22 and the spring 32, so that the fixing pin 21 will not fall down automatically (shown in fig. 12 d). Then, the drawing member 20 is held by one or both hands to be drawn out, so that the drawing member 20 can be drawn out from the host 10 after the connection plug is separated from the connector 102.
To restore the automatic locking mechanism 2 to the automatic locking function, the user simply pushes the shaft 31 axially outward and compresses the spring 32 to disengage the second tenon 313 from the first tenon 213, thereby unlocking the retaining pin 21 and restoring the retaining pin 21 to the configuration shown in fig. 12 a.
As shown in fig. 10 and 11, the pair of fixing rails 1 are fixed to the first plate 101 of the host 10 at intervals, for example, two inner sides of a hole 105 of a motherboard, so as to form a shape in the board. The pair of fixed rails 1 are provided for insertion and extraction of the extracting member 20, such as a web card, and the first plate 101 is provided with a connector 102 at the plate hole 105 and the ends of the pair of fixed rails 1. The way of inserting the extracting element 20 into the host 10 is the same as the above-mentioned on-board type, and will not be described herein. Therefore, when the pair of fixed rails 1 is implemented in the in-board state, the extracting member 20 is not separated from the main body 10 due to the vibration environment.
As shown in fig. 14 and 14a, in order to disclose a second embodiment of the sliding assist link assembly, which is different from the first embodiment in that the same reference numerals (symbols) are used to denote the same components, only the differences will be described in detail since the second embodiment shares many shared components with the first embodiment.
For convenience of description, the second embodiment only discloses a single fixing rail 1, and the difference between the present embodiment and the previous embodiments is that at least two flanges 155 are protruded from the outer circumferential surface of the spring column 154, and each flange 155 has an inclined surface, so that the elastic body 22 is not separated after the ring 223 of the elastic body 22 is sleeved on the spring column 154, and the elastic body 22 has a good fixing effect.
As shown in fig. 15 and 15a, to disclose a third embodiment of the sliding assist link assembly, the third embodiment uses the same reference numerals (symbols) to refer to the same components as compared to the first embodiment, and since the second embodiment shares many shared components with the first embodiment, only the differences will be described in detail.
Similarly, for convenience of illustration, the third embodiment also discloses only a single fixed rail 1, and the difference between the present embodiment and the previous embodiments is that the elastic body 22 is a U-shaped wire spring instead of the torsion spring, and the U-shaped wire spring also has a fixed end 221 and an engaging end 222. The positioning tower 15 is provided with a fixing groove 156 for mounting the fixing end 221 on the opposite side of the manual unlocking mechanism 3, and the engaging end 222 passes through the positioning tower 15 and is inserted into a pair of pin holes 216 opened in opposite directions of the fixing pin 21, thereby completing the process of attaching the elastic body 22 to the positioning tower 15 and the fixing pin 21 as shown in fig. 16.
Referring to fig. 17 and 18, cross-sectional views of the resilient body 22, such as a U-shaped wire spring, in the automatic locking configuration and the manual unlocking configuration are shown, respectively, and it is clear from the drawings that the U-shaped wire spring has the same energy storage and release functions as the aforementioned torsion spring and can achieve the desired automatic locking function.
Therefore, through the implementation of the invention, the beneficial effects comprise: the pair of fixed rails of the sliding auxiliary connecting assembly can form the type on or in the board on the first board with different types, and the automatic locking mechanism which automatically locks the locking hole is arranged at the position of the at least one fixed rail corresponding to the default locking hole of the second board, so that the extracting piece, such as a network card, containing the second board, such as a circuit board can generate an automatic locking function on a host, such as a server, containing the first board, such as a mainboard, in the sliding process of the pair of fixed rails, and the connector of the first board is prevented from being separated from the connecting plug of the second board, so as to ensure the stability of electric connection.
