[0074] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the pull-out device 1 comprises a pull-out body 11, a base 12, a plug-in part 13 and a locking mechanism 14. The plug-in part 13 is fixedly connected to the insertion end of the pull-out body 11, and the plug-in part 13 is movable relative to the base 12 along the plug-in direction.

[0075] The locking mechanism 14 is arranged between the base 12 and the plug-in part 13, and comprises a resettable guide body 141, a guide rod 142 and a limiting part 143. The first end of the guide rod 142 is connected to the base 12, and the second end of the guide rod 142 is movably connected to the guide body 141. The first end of the limiting part 143 is connected to the base 12, and the second end of the limiting part 143 is connected or separated from the plug-in part 13.

[0077] In the embodiments of the present application, since the plug-in part 13 is fixedly connected to the insertion end of the pull-out body 11, the movement state of the pull-out body 11 is always consistent with that of the plug-in part 13, so that the movement state of the pull-out body 11 can be controlled by controlling the movement state of the plug-in part 13. Then, since the plug-in part 13 can move relative to the base 12 along the plug-in direction, the pull-out body 11 can move relative to the base 12, thereby realizing the pull-out function of the pull-out body 11 relative to the base 12.

[0078] Then, the first end of the guide rod 142 is connected with the base 12, and the second end of the guide rod 142 is movably connected with the guide body 141.

Then, since the first end of the limiting part 143 is connected with the base 12 and the second end of the limiting part 143 is connected with or separated from the plug-in part 13, the connection or separation of the limiting part 143 with the plug-in part 13 can realize the connection or separation of the pull-out body 11 with the base 12.

[0079] When the plug-in part 13 is forced to move once along the plug-in direction, the guide rod 142 drives the guide body 141 to move to the locking position, the second end of the limiting part 143 is connected with the plug-in part 13, at this time, the locking mechanism 14 is in the locking state, the plug-in part 13 is connected with the base 12, so that the pull-out body 11 and the base 12 are locked. When the plug-in part 13 is forced to move once along the plug-in direction again, the guide rod 142 drives the guide body 141 to move to the unlocking position, the second end of the limiting part 143 is separated from the plug-in part 13, at this time, the locking mechanism 14 is in the unlocking state, the plug-in part 13 is separated from the base 12, so that the pull-out body 11 and the base 12 are unlocked.

[0080] In summary, when the pull-out device 1 is used, the pull-out body 11 can be locked or unlocked with the base 12 by pressing the pull-out body 11 along the plug-in direction of the plug-in part 13. The operation is relatively simple, and the pull-out body 11 and the base 12 can be locked or unlocked more conveniently.

[0094] In the embodiment of the application, the first groove section 14111, the second groove section 14112 and the third groove section 14113 constitute the locking groove section, and the bottom surfaces of the first groove section 14111, the second groove section 14112 and the third groove section 14113 are smoothly connected. In this way, when the second end of the guide rod 142 moves along the locking groove section, there is no jamming phenomenon, and the moving process can be smoothly completed, thereby enabling the guide body 141 to be smoothly moved to the locking position, so that the locking mechanism 14 can be smoothly switched to the locked state.

[0095] Then, the fourth groove section 14114, the fifth groove section 14115 and the first groove section 14111 constitute the unlocking groove section, the bottom surfaces of the third groove section 14113, the fourth groove section 14114 and the fifth groove section 14115 are smoothly connected, and the depth of the first groove section 14111 is greater than the depth of the fifth groove section 14115. In this way, when the second end of the guide rod 142 moves along the unlocking groove section, it moves smoothly along the direction from the fourth groove section 14114 to the first groove section 14111, and there is no jamming phenomenon in the moving process, thereby enabling the guide body 141 to be smoothly moved to the unlocking position, so that the locking mechanism 14 can be smoothly switched to the unlocked state.

[0096] Then, since the second slot section 14112, the third slot section 14113, the fourth slot section 14114 and the fifth slot section 14115 are sequentially connected end to end to form a ring-shaped slot, one end of the first slot section 14111 is connected to the intersection of the second slot section 14112 and the fifth slot section 14115. A ridge is formed at the intersection of the first slot section 14111 and the fifth slot section 14115, so that the guide rod 142 can only move from the fifth slot section 14115 to the first slot section 14111, but cannot move from the first slot section 14111 to the fifth slot section 14115. In this way, when the second end of the guide rod 142 moves to the intersection of the second slot section 14112 and the fifth slot section 14115 along the first slot section 14111, it can only continue to move along the second slot section 14112, but cannot move along the fifth slot section 14115, thereby enabling the guide rod 142 to move in a specified direction. Specifically, during the process of completing locking and unlocking once, the second end of the guide rod 142 can only move in the direction of the first slot section 14111, the second slot section 14112, the third slot section 14113, the fourth slot section 14114, the fifth slot section 14115 and the first slot section 14111 in sequence, thereby enabling the guide body 141 to switch between the locking position and the unlocking position regularly, and enabling the locking mechanism 14 to switch between the locking state and the unlocking state regularly.

[0097] Then, since the first slot section 14111 and the fifth slot section 14115 are both linear slot sections along the plug-in direction, the second slot section 14112 deviates from the fifth slot section 14115 at the intersection of the second slot section 14112 and the fifth slot section 14115. In this way, when the second end of the guide rod 142 moves along the locking slot section, the movement trajectory thereof is a curve or a broken line, and when the second end of the guide rod 142 moves along the unlocking slot section, the movement trajectory thereof is a straight line along the plug-in direction.

[0098] Then, since the third slot section 14113 and the fourth slot section 14114 form a V-shaped slot section, the opening of the V-shaped slot section is opposite to the plug-in direction. When the guide body 141 is in the locking position, the second end of the guide rod 142 is located at the intersection of the third slot section 14113 and the fourth slot section 14114, and the limiting hook 1431 is connected to the plug-in piece 13. In this way, the second end of the guide rod 142 can limit the guide body 141 through the V-shaped slot section, so that the guide body 141 is located in the locking position, thereby enabling the locking mechanism 14 to switch to the locking state.

[0099] Then, since the base 12 is provided with the limiting groove 121, the depth of the limiting groove 121 gradually decreases along the plug-in direction, and the limiting pull hook 1431 is located in the limiting groove 121 and slides along the limiting groove 121 to connect or separate the limiting pull hook 1431 from the plug-in piece 13. Specifically, when the guide body 141 moves to the locking position along the plug-in direction, the limiting pull hook 1431 can protrude from the limiting groove 121 and be connected with the plug-in piece 13, at this time, the locking mechanism 14 is in the locking state; when the guide body 141 moves to the unlocking position along the opposite direction of the plug-in direction, the limiting pull hook 1431 can enter the inside of the limiting groove 121 and be separated from the plug-in piece 13, at this time, the locking mechanism 14 is in the unlocking state. In this way, the limiting pull hook 1431 can be connected or separated from the plug-in piece 13, so that the locking mechanism 14 can be switched between the locking state and the unlocking state.

[0100] Then, since the limiting pull hook 1431 is provided with the round corner 14311 on the side away from the second end of the limiting piece 143, when the locking mechanism 14 is in the locking state, the plug-in piece 13 moves along the plug-in direction, and the plug-in piece 13 collides with the round corner 14311 to make the limiting pull hook 1431 move perpendicularly to the plug-in direction, enter the inside of the limiting groove 121 and separate the plug-in piece 13 from the limiting pull hook 1431. In this way, the limiting pull hook 1431 can be more easily separated from the plug-in piece 13, so that the unlocking process is more smooth.

[0101] In some embodiments, the V-shaped groove segment described above can also be a semicircular groove segment, at this time, the third groove segment 14113 and the fourth groove segment 14114 are both circular arcs, and the third groove segment 14113 and the fourth groove segment 14114 are connected to form a semicircular groove segment. When the second end of the guide rod 142 moves to the midpoint of the semicircular groove segment, the guide body 141 is in the locking position, the limiting pull hook 1431 is connected with the plug-in piece 13, and the locking mechanism 14 can be switched to the locking state. When the second end of the guide rod 142 continues to move to the intersection between the fourth groove segment 14114 and the fifth groove segment 14115, the guide body 141 with the reset function can move in the opposite direction of the plug-in direction, at this time, the second end of the guide rod 142 moves along the direction of the fifth groove segment 14115 and the first groove segment 14111, so that the guide body 141 moves to the unlocking position. Further, the guide body 141 can be regularly switched between the locking position and the unlocking position, so that the locking mechanism 14 can be regularly switched between the locking state and the unlocking state. In addition, after the semicircular groove segment replaces the V-shaped groove segment, the second end of the guide rod 142 can move more smoothly, and thus the pull-out device 1 can be used more comfortably.

[0102] Optionally, in some embodiments, referring to Figure 3 , Figure 4 , Figure 9 and Figure 11The guide body 141 includes a guide block 1412 and an elastic member 1413. The first end of the elastic member 1413 is connected to the base 12 along the plug-in direction, and the second end of the elastic member 1413 is connected to the guide block 1412. When the elastic member 1413 is stretched and contracted, the guide block 1412 can be moved relative to the base 12 along the plug-in direction.

[0103] In the embodiment, the guide groove 1411 is arranged on the surface of the guide block 1412, and the second end of the guide rod 142 is slidably connected to the guide groove 1411 on the surface of the guide block 1412. Since the first end of the elastic member 1413 is connected to the base 12 along the plug-in direction, and the second end of the elastic member 1413 is connected to the guide block 1412, when the elastic member 1413 is stretched and contracted, the guide block 1412 can be moved relative to the base 12 along the plug-in direction. Specifically, when the second end of the guide rod 142 moves along the locking groove section, the elastic member 1413 is stretched, and the guide block 1412 is subjected to the elastic force of the elastic member 1413, so that the second end of the guide rod 142 abuts against the intersection of the third groove section 14113 and the fourth groove section 14114. At this time, the locking mechanism 14 is in the locked state. When the second end of the guide rod 142 moves along the unlocking groove section to the intersection of the fourth groove section 14114 and the fifth groove section 14115, the guide block 1412 is moved to the unlocking position under the action of the elastic force. At this time, the locking mechanism 14 is in the unlocked state.

[0104] Since the elastic member 1413 has the ability to deform repeatedly and is mature in technology and low in cost, the elastic member 1413 is used to provide the guide block 1412 with elastic force to realize the resetting function of the guide body 141, so that the locking structure is more stable and the cost is lower.

[0105] Optionally, in some embodiments, referring to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 11 , the elastic member 1413 is a tension spring, and the plug-in piece is a plug-in sheet. The plug-in sheet is provided with an avoiding hole 131 at a position corresponding to the spring.

[0106] In the embodiment, since the elastic member 1413 is a tension spring, the spring is a common elastic member 1413 and is low in cost and has good heat resistance. Therefore, the cost of the locking mechanism can be reduced, the heat resistance of the locking mechanism is improved, and the locking mechanism is more suitable for use in a server case.

[0107] Then, since the plug-in piece is a plug-in sheet, the plane of the plug-in sheet is parallel to the plane of the base 12. Therefore, the volume of the locking mechanism 14 can be reduced, and the volume of the pulling device 1 can be reduced.

[0108] Then, the extension spring is arranged in the avoiding hole 131 due to the avoiding hole 131 arranged at the position corresponding to the spring of the plug-in piece. Thus, the plug-in piece can be directly attached to the guide block 1412, thereby reducing the thickness of the locking mechanism 14 as a whole, and further reducing the volume of the locking mechanism 14, and further reducing the volume of the pull-out device 1.

[0109] Optionally, in some embodiments, referring to Figure 3 、 Figure 4 and Figure 7 , the guide rod 142 comprises a first connecting rod 1421, a guide main rod 1422 and a second connecting rod 1423 arranged in sequence; the first connecting rod 1421 is located at the first end of the guide rod 142, is perpendicular to the guide main rod 1422 and is rotationally connected to the base 12; the second connecting rod 1423 is located at the second end of the guide rod 142, is perpendicular to the guide main rod 1422 and extends into the guide groove 1411 and is slidingly connected to the guide groove 1411.

[0110] Specifically, the first connecting rod 1421 is parallel to the second connecting rod 1423, so that when the second connecting rod 1423 at the second end of the guide rod 142 moves to the intersection of the third groove segment 14113 and the fourth groove segment 14114, the pressure applied by the guide block 1412 to the second connecting rod 1423 and the pressure applied by the base 12 to the first connecting rod 1421 are in opposite directions, so that the guide rod 142 is more easily balanced under force, and thus the locking mechanism 14 is more stable in the locked state, and thus the pull-out device 1 is more stable in the locked state.

[0111] Optionally, in some embodiments, referring to Figure 3 、 Figure 4 、 Figure 10 and Figure 12 , the base 12 is provided with a sliding strip 122, and the guide block 1412 is provided with a sliding groove 14121, and the sliding strip 122 and the sliding groove 14121 are slidingly connected, so that the guide block 1412 can slide relative to the base 12.

[0112] In the embodiments of the present application, the sliding strip 122 and the sliding groove 14121 are slidingly connected to play a guiding role, so that the guide block 1412 can slide directionally between the locked position and the unlocked position when moving relative to the base 12, so that the guide block 1412 can be prevented from deviating from the moving path during movement, and thus the locking mechanism 14 is more stable. In addition, the sliding strip 122 moves relative to the sliding groove 14121 with smaller friction, and thus the wear between the guide block 1412 and the base 12 can be reduced, and thus the service life of the locking mechanism 14 can be prolonged, and thus the service life of the pull-out device 1 can be prolonged.

[0113] Optionally, in some embodiments, referring to Figure 3、 Figure 4 and Figure 12 The edge of the base 12 is further provided with a side edge stop strip 123 which is in sliding connection with the side surface of the guide block 1412.

[0114] Specifically, the side edge stop strip 123 can play a guiding role to guide the movement of the guide block 1412 in the plugging direction, and can also play a lateral limiting role to prevent the guide block 1412 from slipping off the side edge of the base 12. Thus, the stability of the locking mechanism 14 is enhanced.

[0115] Optionally, in some embodiments, referring to Figure 13 、 Figure 14 、 Figure 15 The pulling body 11 comprises a pulling base 111, a plurality of partition plates 112 and a cover plate 113, the pulling base 111 and the cover plate 113 are fixedly connected and enclose a cavity 114; the first side edge of each partition plate 112 is fixedly connected with the pulling base 111, and the second side edge of each partition plate 112 is fixedly connected with the cover plate 113, the first side edge and the second side edge are oppositely arranged; the plurality of partition plates 112 divide the cavity 114 into a plurality of sub-cavities 114.

[0116] The plurality of sub-cavities 114 can be used to accommodate cables of servers, so that the cables in each sub-cavity 114 are independently arranged and do not affect each other, thereby reducing the probability of cable failure. In addition, when the cables need to be repaired, the independently arranged cables are convenient to repair, and the situation of cable disorder and disentanglement does not occur, so the efficiency of cable repair can be improved.

[0117] Optionally, in some embodiments, referring to Figure 13 、 Figure 14 、 Figure 16 and Figure 17 The partition plate 112 comprises a first partition plate 1121 and a second partition plate 1122, and the first partition plate 1121 and the second partition plate 1122 are connected in abutment to constitute the partition plate 112.

[0118] Since the cables generate heat during operation, holes are arranged on the partition plates for heat dissipation of the cables. If only one layer of holes is arranged on each partition plate, the cables in adjacent sub-cavities 114 can also contact through the holes, so the cables in adjacent sub-cavities 114 still affect each other.

[0119] After the partition is arranged as a double-layer structure including the first partition 1121 and the second partition 1122, the cables inside the adjacent sub-cavities 114 cannot directly contact each other, so that the cables inside the adjacent sub-cavities 114 cannot affect each other, thereby reducing the probability of failure. In addition, the double-layer partition structure has a better heat dissipation effect than the single-layer partition structure.

[0120] Referring to Figure 13 , Figure 14 , Figure 16 and Figure 17 , the first partition 1121 is provided with a first riveting hole 11211, a first limiting convex bump 11212, a first sliding channel 11213, a first positioning hole, a first upper bending sliding channel, a first upper top plate and a first mounting bump; the second partition 1122 is provided with a second sliding channel 11221, a second riveting convex bump 11222 and a second upper top plate 11223; the second riveting convex bump 11222 is inserted into the first riveting hole 11211 to make the first partition 1121 and the second partition 1122 connected in close contact.

[0121] The second partition 1122 includes a second sliding channel 11221, a hard disk stop, a riveting sprout and a bracket stop. The hard disk stop limits the front and back directions after the hard disk is installed; the riveting sprout cooperates with the first partition 1121; the bracket stop is in abutment with the stepped portion of the hard disk bracket, thereby limiting the excessive insertion of the hard disk bracket.

[0122] Referring to Figure 13 , Figure 14 and Figure 15 , the pull-out base 111 is provided with a bottom convex bridge 1111, a bottom plate 1112, a partition installation sunken convex bump 1113, a back plate support installation convex bump, a back plate avoidance hole, a push-pull self-locking sliding block 116 installation bump, a pull-out sliding channel, an anti-collision flange, a support sliding channel installation hole, a hard disk side edge stop, a first hard disk bracket left side sliding channel and a second hard disk bracket sliding channel; the bottom convex bridge 1111 is in contact with the bottom surface of the hard disk bracket to lift the hard disk bracket; the partition installation sunken convex bump 1113 is used for connecting the partition 112; the back plate support installation convex bump is used for ensuring that the back plate support is tightly attached to the bottom surface after installation.

[0124] Referring to Figure 20 , the pulling body 11 further comprises a push-pull self-locking slider 116 arranged at the bottom of the pulling base 111; the push-pull self-locking slider 116 is provided with a wedge surface 1161, a tapered hole 1162, a positioning boss 1163 and a stop step 1164; the wedge surface 1161 is in sliding connection with the wedge surface of the guide block 1412 during sliding to push the guide block 1412 to move; the tapered hole 1162 is in matched connection with the mounting protrusion; the positioning boss 1163 is matched with the special-shaped hole on the pulling base 111 to form positioning before installation of the push-pull self-locking slider 116, facilitating installation of the push-pull self-locking slider 116 on the pulling base 111; the stop step 1164 can stop when the hard disk module is pushed to the limit position, at which time no external force is applied and the hard disk module is in a locked state.

[0125] Referring to Figure 21 , Figure 22 and Figure 23 , the pulling body 11 further comprises a backboard support module 117 fixedly connected with the insertion end of the pulling body 11.

[0127] Optionally, in some embodiments, referring to Figure 1and Figure 18 The pulling device 1 further comprises a pulling box body 15 which is detachably connected with the pulling body 11 perpendicularly to the plugging direction.

[0128] The pulling device 1 in the prior art generally only comprises the pulling body 11, that is, only one layer of pulling structure, but one layer of pulling structure can only realize the maintenance of the cables inside the server case at a certain layer, and cannot maintain all the cables inside the server case. This causes the difficulty in maintaining the cables and modules inside the server, and even needs to open the cover for maintenance, which is poor in operability and low in installation and maintenance efficiency.

[0129] After the pulling device 1 is further provided with the pulling box body 15 which is connected with the pulling body 11, the cables at the layer where the pulling box body 15 is located can be maintained. This makes it more convenient to maintain more cables, improves the working efficiency of the maintenance personnel, and can save labor cost and processing cost.

[0130] Optionally, in some embodiments, referring to Figure 1 , Figure 18 , Figure 24 and Figure 25 , the pulling box body 15 comprises a pulling tray 151, a modular rear window 152 and a power supply support 153; the bottom of the modular rear window 152 is fixedly connected with the pulling tray 151, and the bottom of the power supply support 153 is fixedly connected with the pulling tray 151.
