[0072] The pull-out device and the server chassis provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0073] Figure 1 is a structural schematic diagram of a pulling device 1 provided in an embodiment of the present invention, Figure 2 It is a schematic diagram of the structure after the base 12, the connector 13 and the locking mechanism 14 are connected as a whole. Figure 3 is a schematic diagram of the structure after the base 12 and the locking mechanism 14 are connected as a whole. Figure 4 yes Figure 2 The corresponding exploded diagram.

[0074] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The drawer device 1 comprises: a drawer body 11, a base 12, a plug connector 13 and a locking mechanism 14. The plug connector 13 is fixedly connected to the insertion end of the drawer body 11, and the plug connector 13 can move relative to the base 12 along the plugging direction.

[0075] The locking mechanism 14 is arranged between the base 12 and the connector 13, and includes a resettable guide body 141, a guide rod 142 and a limit member 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 limit member 143 is connected to the base 12, and the second end of the limit member 143 is connected to or separated from the connector 13.

[0076] When the connector 13 is subjected to force and moves once in the plugging direction, the guide rod 142 drives the guide body 141 to move to the locked position, and the second end of the limit member 143 is connected to the connector 13. At this time, the locking mechanism 14 is in a locked state, and the connector 13 is connected to the base 12; when the connector 13 is subjected to force again and moves once in the plugging direction, the guide rod 142 drives the guide body 141 to move to the unlocked position, and the second end of the limit member 143 is separated from the connector 13. At this time, the locking mechanism 14 is in an unlocked state, and the connector 13 is separated from the base 12.

[0077] In the embodiment of the present application, since the plug connector 13 is fixedly connected to the insertion end of the drawer body 11, the movement state of the drawer body 11 is always consistent with the plug connector 13, so the movement state of the drawer body 11 can be controlled by controlling the movement state of the plug connector 13. Then, since the plug connector 13 can move relative to the base 12 along the plugging direction, the drawer body 11 can move relative to the base 12, thereby realizing the drawer body 11 relative to the base 12.

[0078] Next, 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. In this way, the base 12 and the guide body 141 are movably connected through the guide rod 142, so that the guide body 141 can move relative to the base 12. Next, since the first end of the stopper 143 is connected to the base 12, the second end of the stopper 143 is connected to or separated from the plug-in connector 13. In this way, the connection or separation of the drawer body 11 and the base 12 can be achieved by connecting or separating the stopper 143 and the plug-in connector 13.

[0079] When the connector 13 is stressed and moves once in the plugging direction, the guide rod 142 drives the guide body 141 to move to the locked position, and the second end of the limiter 143 is connected to the connector 13. At this time, the locking mechanism 14 is in a locked state, and the connector 13 is connected to the base 12, so that the drawer body 11 and the base 12 are locked. When the connector 13 is stressed again and moves once in the plugging direction, the guide rod 142 drives the guide body 141 to move to the unlocked position, and the second end of the limiter 143 is separated from the connector 13. At this time, the locking mechanism 14 is in an unlocked state, and the connector 13 is separated from the base 12, so that the drawer body 11 and the base 12 are unlocked.

[0080] In summary, when the above-mentioned drawer device 1 is used, the drawer body 11 can be locked or unlocked with the base 12 by simply pressing the drawer body 11 along the plugging direction of the plug connector 13. This operation is relatively simple, and can make it more convenient to lock or unlock the drawer body 11 and the base 12.

[0081] Optionally, in some embodiments, see Figure 3 , Figure 4, Figure 8 , Fig. 9 and Fig.10 The guide body 141 is provided with a guide groove 1411, and the guide groove 1411 includes a locking groove section and an unlocking groove section which are continuously arranged;

[0082] The first end of the guide rod 142 is rotatably connected to the base 12, the second end of the guide rod 142 extends into the guide groove 1411 and is slidably connected to the groove wall of the guide groove 1411, and the second end of the guide rod 142 can move along the extension direction of the guide groove 1411;

[0083] The first end of the limiting member 143 is rotatably connected to the base 12, and the second end of the limiting member 143 is provided with a limiting hook 1431, which can move along a direction perpendicular to the insertion direction of the plug-in component 13 to connect or separate the plug-in component 13 from the limiting hook 1431;

[0084] When the second end of the guide rod 142 moves along the locking groove section, the guide body 141 moves to the locking position, and the limiting hook 1431 is connected to the connector 13; when the second end of the guide rod 142 moves along the unlocking groove section, the guide body 141 moves to the unlocking position, and the limiting hook 1431 is separated from the connector 13.

[0085] In the embodiment of the present application, since the first end of the guide rod 142 is rotatably connected to the base 12, the second end of the guide rod 142 extends into the guide groove 1411 and is slidably connected to the groove wall of the guide groove 1411, and the second end of the guide rod 142 can move along the extension direction of the guide groove 1411. In this way, the guide rod 142 can rotate relative to the base 12 on the basis of being able to connect the base 12 and the guide body 141. Therefore, when the guide groove 1411 extends in any direction, the second end of the guide rod 142 can move along the extension direction of the guide groove 1411, so that the guide rod 142 moves more smoothly.

[0086] Next, since the first end of the stopper 143 is rotatably connected to the base 12, the second end of the stopper 143 is provided with a stopper hook 1431, which can move in a direction perpendicular to the insertion direction of the plug-in connector 13 to connect or disconnect the plug-in connector 13 with the stopper hook 1431. Specifically, when the base 12 is placed horizontally, the stopper hook 1431 can move up and down in the vertical direction, so that the plug-in connector 13 and the base 12 can be connected or disconnected to achieve locking or unlocking between the plug-in connector 13 and the stopper hook 1431, thereby achieving locking or unlocking between the drawer body 11 and the base 12.

[0087] Next, since the guide body 141 is provided with a guide groove 1411, the guide groove 1411 includes a locking groove section and an unlocking groove section which are continuously arranged. When the second end of the guide rod 142 moves along the locking groove section, the guide body 141 moves to the locking position, and the limit hook 1431 is connected with the plug connector 13. At this time, the limit hook 1431 can limit the plug connector 13 from moving in the opposite direction of the plug-in direction, and then the plug connector 13 can be connected with the base 12, and the locking mechanism 14 is in a locked state. When the second end of the guide rod 142 moves along the unlocking groove section, the guide body 141 moves to the unlocking position, and the limit hook 1431 is separated from the plug connector 13. At this time, the plug connector 13 is freed from the restriction of the limit hook 1431 and moves in the opposite direction of the plug-in direction, and then the plug connector 13 is separated from the base 12, and the locking mechanism 14 is in an unlocking state.

[0088] Optionally, in some embodiments, see Figure 3 , Figure 4 , Fig. 9 , Fig.10 and Fig.12 The guide groove 1411 includes a first groove section 14111, a second groove section 14112, a third groove section 14113, a fourth groove section 14114 and a fifth groove section 14115; the second groove section 14112, the third groove section 14113, the fourth groove section and the fifth groove section 14115 are connected end to end in sequence to form an annular groove, and one end of the first groove section 14111 is connected to the intersection of the second groove section 14112 and the fifth groove section 14115;

[0089] The first groove section 14111, the second groove section 14112 and the third groove section 14113 constitute a 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;

[0090] The fourth slot section 14114, the fifth slot section 14115 and the first slot section 14111 constitute an unlocking slot section, and the bottom surfaces of the third slot section 14113, the fourth slot section 14114 and the fifth slot section 14115 are smoothly connected; the depth of the first slot section 14111 is greater than the depth of the fifth slot section 14115, and a step 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; the first slot section 14111 and the fifth slot section 14115 are both linear slot sections along the plugging direction;

[0091] The third groove section 14113 and the fourth groove section 14114 form a V-shaped groove section, the opening of the V-shaped groove section is opposite to the plug-in direction, when the guide body 141 is in the locked position, the second end of the guide rod 142 is located at the intersection of the third groove section 14113 and the fourth groove section 14114, and the limiting hook 1431 is connected to the plug-in component 13;

[0092] The base 12 is provided with a limiting groove 121, the depth of which gradually decreases along the plugging direction, and the limiting hook 1431 is located in the limiting groove 121 and slides along the limiting groove 121 to connect or separate the limiting hook 1431 from the plug-in component 13;

[0093] A rounded corner 14311 is provided on one side of the limiting hook 1431 away from the second end of the limiting member 143. When the locking mechanism 14 is in the locked state, the connector 13 moves along the plugging direction, and the connector 13 collides with the rounded corner 14311 to make the limiting hook 1431 move perpendicular to the plugging direction, thereby separating the connector 13 from the limiting hook 1431.

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

[0095] Next, since the fourth groove section 14114, the fifth groove section 14115 and the first groove section 14111 constitute an 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; the depth of the first groove section 14111 is greater than the depth of the fifth groove section 14115, so 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 will be no jamming during the movement, thereby driving the guide body 141 to move smoothly to the unlocking position, so that the locking mechanism 14 can be smoothly switched to the unlocking state.

[0096] Next, since the second slot section 14112, the third slot section 14113, the fourth slot and the fifth slot section 14115 are connected end to end in sequence to form an annular 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 step 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, and 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 along the first slot section 14111 to the intersection of the second slot section 14112 and the fifth slot section 14115, it can only continue to move along the second slot section 14112, and cannot move along the fifth slot section 14115, so that the guide rod 142 can only move along the specified direction. Specifically, in the process of completing a locking and unlocking, the second end of the guide rod 142 can only move in a directional manner along the directions 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, so that the guide body 141 can be regularly switched between the locked position and the unlocked position, so that the locking mechanism 14 can be regularly switched between the locked state and the unlocked state.

[0097] Next, since the first slot section 14111 and the fifth slot section 14115 are both straight slot sections along the plugging 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. Thus, when the second end of the guide rod 142 moves along the locking slot section, its moving track is a curve or a broken line, and when it moves along the unlocking slot section, its moving track is a straight line along the plugging direction.

[0098] Next, since the third groove section 14113 and the fourth groove section 14114 form a V-shaped groove section, the opening of the V-shaped groove section is opposite to the plug-in direction, when the guide body 141 is in the locked position, the second end of the guide rod 142 is located at the intersection of the third groove section 14113 and the fourth groove section 14114, and the limiting hook 1431 is connected to the plug-in connector 13. In this way, the second end of the guide rod 142 can limit the guide body 141 through the V-shaped groove section, so that the guide body 141 is located in the locked position, and the locking mechanism 14 can be switched to the locked state.

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

[0100] Next, since the side of the limiting hook 1431 away from the second end of the limiting member 143 is provided with a rounded corner 14311, when the locking mechanism 14 is in the locked state, the plug-in component 13 moves along the plug-in direction, and the plug-in component 13 hits the rounded corner 14311, so that the limiting hook 1431 can move perpendicularly to the plug-in direction, enter the inside of the limiting groove 121, and separate the plug-in component 13 from the limiting hook 1431. In this way, the limiting hook 1431 is easier to separate from the plug-in component 13, making the unlocking process smoother.

[0101] In some embodiments, the V-shaped groove section may also be a semicircular groove section, in which case the third groove section 14113 and the fourth groove section 14114 are both arc-shaped, and the third groove section 14113 and the fourth groove section 14114 are connected to form a semicircular groove section. When the second end of the guide rod 142 moves to the midpoint of the semicircular groove section, the guide body 141 is in the locked position, the limit hook 1431 is connected to the connector 13, and the locking mechanism 14 can be switched to the locked state. When the second end of the guide rod 142 continues to move to the intersection of the fourth groove section 14114 and the fifth groove section 14115, the guide body 141 with a 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 section 14115 and the first groove section 14111, so that the guide body 141 moves to the unlocking position. The guide body 141 can be switched regularly between the locked position and the unlocked position, so the locking mechanism 14 can be switched regularly between the locked state and the unlocked state. In addition, after the V-shaped groove section is replaced with a semicircular groove section, the second end of the guide rod 142 can move more smoothly, making the pull-out device 1 more comfortable to use.

[0102] Optionally, in some embodiments, see Figure 3 , Figure 4 , Fig. 9 and Fig.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 extended or retracted, it can drive the guide block 1412 to move relative to the base 12 along the plug-in direction.

[0103] In the embodiment of the present application, the guide groove 1411 is provided 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 plugging direction, and the second end of the elastic member 1413 is connected to the guide block 1412, the elastic member 1413 can drive the guide block 1412 to move relative to the base 12 along the plugging direction when it is extended. 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, and the locking mechanism 14 is in a locked state. When the second end of the guide rod 142 moves along the unlocking slot section to the junction of the fourth slot section 14114 and the fifth slot section 14115 , the guide block 1412 moves to the unlocking position under the action of elastic force, and the locking mechanism 14 is in an unlocking state.

[0104] Since the elastic member 1413 has the ability to deform repeatedly and its technology is mature and the cost is low, the elastic member 1413 provides elastic force to the guide block 1412 to realize the reset function of the guide body 141, which can make the locking structure more stable and lower the cost.

[0105] Optionally, in some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9 and Fig.11 The elastic member 1413 is a tension spring, the plug-in member 13 is a plug-in sheet, and an avoidance hole 131 is provided at a position corresponding to the plug-in sheet and the spring.

[0106] In the embodiment of the present application, since the elastic member 1413 is a tension spring, the spring is a common elastic member 1413, has a low cost, and has good heat resistance, so it can reduce the cost of the locking mechanism and improve the heat resistance of the locking mechanism, making it more suitable for use in a server chassis.

[0107] Next, since the plug-in component 13 is a plug-in sheet, the plane of the plug-in sheet is parallel to the plane of the base 12 , which can reduce the volume of the locking mechanism 14 and further reduce the volume of the pulling device 1 .

[0108] Next, since the position corresponding to the plug-in piece and the spring is provided with an avoidance hole 131, the tension spring is arranged in the avoidance hole 131. Therefore, the plug-in piece can be directly attached to the guide block 1412, thereby reducing the overall thickness of the locking mechanism 14, so that the volume of the locking mechanism 14 can be further reduced, and the volume of the pulling device 1 can be further reduced.

[0109] Optionally, in some embodiments, see Figure 3 , Figure 4 and Figure 7 The guide rod 142 includes a first connecting rod 1421, a guide main rod 1422 and a second connecting rod 1423 which are continuously arranged; 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 rotatably 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 slidably 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 junction of the third groove section 14113 and the fourth groove section 14114, the pressure applied to the second connecting rod 1423 by the guide block 1412 is in opposite directions to the pressure applied to the first connecting rod 1421 by the base 12, so that the guide rod 142 is more easily subjected to force balance, thereby making the locking mechanism 14 more stable when in a locked state, and thereby making the structure of the pulling device 1 more stable when in a locked state.

[0111] Optionally, in some embodiments, see Figure 3 , Figure 4 , Fig.10 and Fig.12 The base 12 is provided with a slide bar 122 , and the guide block 1412 is provided with a slide groove 14121 . The slide bar 122 is slidably connected with the slide groove 14121 , so that the guide block 1412 can slide relative to the base 12 .

[0112] In the embodiment of the present application, the slide bar 122 can play a guiding role after being slidably connected with the slide groove 14121, so that the guide block 1412 can slide directionally between the locking position and the unlocking position when moving relative to the base 12, so as to prevent the guide block 1412 from deviating from the moving path during the movement, thereby making the locking mechanism 14 more stable. In addition, the slide bar 122 has a small friction force when moving relative to the slide groove 14121, thereby reducing the loss between the guide block 1412 and the base 12, so that the service life of the locking mechanism 14 can be extended, and the service life of the pulling device 1 is also extended.

[0113] Optionally, in some embodiments, see Figure 3, Figure 4 and Fig.12 The edge of the base 12 is also provided with a side stop bar 123, and the side stop bar 123 is slidably connected to the side of the guide block 1412.

[0114] Specifically, the side stopper strip 123 can play a guiding role on the one hand, guiding the guide block 1412 to move along the plugging direction, and on the other hand, the side stopper strip 123 can also play a lateral limiting role, preventing the guide block 1412 from slipping off the side of the base 12, thereby enhancing the stability of the locking mechanism 14.

[0115] Optionally, in some embodiments, see Fig.13 , Fig.14 and Fig.15 The pull-out body 11 includes a pull-out base 111, multiple partition plates 112 and a cover plate 113. The pull-out base 111 and the cover plate 113 are fixedly connected and enclosed to form a cavity 114; the first side of each partition plate 112 is fixedly connected to the pull-out base 111, and the second side of each partition plate 112 is fixedly connected to the cover plate 113, and the first side and the second side are arranged opposite to each other; the multiple partition plates 112 divide the cavity 114 into multiple sub-cavities 114.

[0116] The interior of multiple sub-cavities 114 can be used to accommodate cables of the server, so that the cables in each sub-cavity 114 are independently arranged without affecting each other, thereby reducing the probability of cable failure. In addition, when the cables need to be repaired, the independently arranged cables are also easy to repair, and there will be no situation where the cables are messy and cannot be sorted out, so the efficiency of cable maintenance can be improved.

[0117] Optionally, in some embodiments, see Fig.13 , Fig.14 , Fig.16 and Fig.17 The partition plate 112 includes a first partition plate 1121 and a second partition plate 1122 , and the first partition plate 1121 and the second partition plate 1122 are bonded and connected to form the partition plate 112 .

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

[0119] After the partition is set to a double-layer structure including the first partition 1121 and the second partition 1122, the cables in adjacent sub-cavities 114 cannot directly contact each other, which can avoid the cables in adjacent sub-cavities 114 from affecting 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] See also Fig.13 , Fig.14 , Fig.16 and Fig.17 The first partition 1121 is provided with a first riveting hole 11211, a first limiting convex bump 11212, a first slide 11213, a first positioning hole, a first upper bending slide, a first upper top plate and a first mounting protrusion; the second partition 1122 is provided with a second slide 11221, a second riveting protrusion 11222 and a second upper top plate 11223; the second riveting protrusion 11222 is inserted into the first riveting hole 11211 to make the first partition 1121 and the second partition 1122 fit and connect.

[0121] The second partition 1122 includes a second slide 11221, a hard disk stopper, a riveted bud and a bracket stopper. The hard disk stopper limits the front and rear directions of the hard disk after installation; the riveted bud cooperates with the first partition 1121; the bracket stopper abuts against the step portion of the hard disk bracket, limiting the over-insertion of the hard disk bracket.

[0124] See also Fig. 20 The drawer body 11 also includes a push-pull self-locking slider 116, which is arranged at the bottom of the drawer base 111; the push-pull self-locking slider 116 is provided with a wedge surface 1161, a salad cone hole 1162, a positioning boss 1163 and a stop step 1164; the wedge surface 1161 is slidably connected with the wedge plane of the guide block 1412 during the sliding process to push the guide block 1412 to move; the salad cone hole 1162 is matched with the installation convex point. The positioning boss 1163 is matched with the special-shaped hole on the drawer base 111 to form the positioning of the push-pull self-locking slider 116 before installation, which is convenient for the installation of the push-pull self-locking slider 116 on the drawer base 111; the stop step 1164 can be stopped 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] See also Fig.21 , Fig. 22 and Fig.23 The drawer body 11 further includes a back panel bracket module 117, which is fixedly connected to the insertion end of the drawer body 11. The back panel bracket module 117 includes a bracket module body 1171, a bracket fixing bolt 1172, a back panel installation stop hole 1173, an I-shaped nail and a back panel tool-free fixing screw; the fixing bolt is passed through the back panel bracket module 117 to fix the bracket module body 1171 and the drawer body 11.

[0127] Optionally, in some embodiments, see Figure 1and Fig.18 The drawer device 1 further includes a drawer box body 15, which is detachably connected to the drawer body 11 perpendicular to the plug-in direction.

[0128] The drawer 1 in the prior art generally only includes a drawer body 11, that is, only includes a layer of drawer structure, but the layer of drawer structure can only realize the maintenance of the cables inside the server chassis at a certain layer, and cannot maintain all the cables in the server chassis. This makes it difficult to maintain the cables and modules inside the server, and even requires opening the cover for maintenance, which has poor operability and low installation and maintenance efficiency.

[0129] After the drawer 1 is provided with a drawer box 15 that is closely connected to the drawer body 11, the cables can be maintained at the level where the drawer box 15 is located. This makes it more convenient to maintain more cables, improves the work efficiency of the maintenance personnel, and can save labor costs and processing costs.

[0130] Optionally, in some embodiments, see Figure 1 , Fig.18 , Fig.24 and Fig.25 The pull-out box body 15 includes a pull-out tray 151 , a modular rear window 152 and a power supply bracket 153 ; the bottom of the modular rear window 152 is fixedly connected to the pull-out tray 151 , and the bottom of the power supply bracket 153 is fixedly connected to the pull-out tray 151 .

[0131] The modular rear window 152 is riveted to the pull-out tray 151 by rivets, the power supply bracket 153 is riveted to the pull-out tray 151 by rivets, and the side is fixed to the side of the pull-out tray 151 by four rivets.
