Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of servers, and particularly relates to an assisting extractor and electronic equipment. BACKGROUND

[0002] The server device is provided with a pluggable device, which improves the maintainability of the device. During maintenance and upgrading of the server device, some pluggable devices need to be inserted or removed. The assisting extractor can improve the convenience and efficiency of dismounting and mounting the pluggable device, reduce the operation difficulty, reduce the damage of the device, and enhance the safety of the device.

[0003] After the to-be-plugged device is mounted on the server, the assisting extractor is exposed to the case, and is easy to be rotated due to misoperation, so that the to-be-plugged device is pulled out. After the to-be-plugged device is pulled out accidentally, system failure or downtime may be caused. CONTENT OF THE UTILITY MODEL

[0004] To solve the above problems, the assisting extractor and the electronic equipment provided by the present application can reduce the situation that the to-be-plugged device is pulled out accidentally due to misoperation, and improve the safety of the device.

[0005] The assisting extractor provided by the embodiment of the present application comprises a base and a handle. The base is used for connecting a to-be-plugged device. The handle is rotationally connected to the base around a first rotation shaft. The handle is provided with a buckle and a buckle locking mechanism. The buckle is rotationally connected to the handle around a second rotation shaft, and the buckle has a first unlocking position and a first locking position. The base is provided with a clamping groove. When the buckle is located at the first locking position and the buckle is clamped with the clamping groove, the handle is locked with the base. The buckle locking mechanism is rotationally installed on the handle, and the buckle locking mechanism has a second unlocking position and a second locking position. When the buckle locking mechanism is rotated to the second locking position, the buckle is locked at the first locking position.

[0006] In the above embodiment, the device to be plugged or unplugged can be a hard disk module. The handle has an open position and a folded position. When the handle is in the folded position, the handle is buckled with the base. When the handle is in the open position, the handle has an angle with the base. Since the handle is easy to be accidentally rotated when it is in the open position. Therefore, the handle is rotated to the folded position, and the handle is locked with the base. In this way, it can reduce the situation that the handle is accidentally rotated by the operator due to misoperation, resulting in the device to be plugged or unplugged being accidentally pulled out. At the same time, when the buckle locking mechanism is in the second locking position, it can prevent the buckle from rotating along the second rotating shaft, thereby realizing the function of secondary locking of the handle. It avoids the situation that the handle is opened after the handle and the base are accidentally unlocked due to the misoperation of the operator, resulting in the buckle rotating to the first unlocking position. The buckle and the buckle locking mechanism improve the reliability of the extractor, thereby improving the safety of the equipment. In addition, when the handle is in the folded position, the overall structure of the extractor is compact, and the space occupied is small.

[0007] In an embodiment, the handle has a through slot, the buckle is arranged in the through slot, the buckle is L-shaped and includes a button and a connecting rod connected to each other, the second rotating shaft is located between the button and the connecting rod, and the connecting rod extends away from the base.

When the lock pin is rotated to the second locking position, the limiting protrusion abuts against the connecting rod. When the lock pin is rotated to the second unlocking position, the lock plate is spaced apart from the connecting rod by a preset distance. By rotating the lock pin to switch the position of the limiting protrusion of the lock plate, the secondary locking and unlocking of the buckle are realized.

By inserting the groove with an external tool and rotating the lock pin, the unlocking and locking of the snap locking mechanism are realized, the unlocking difficulty is increased, and the situation that the operator accidentally presses the buckle to unlock the buckle is reduced.

[0011] In one embodiment, the extractor further comprises a stop pin installed on the base, the axial direction of the stop pin is parallel to the first rotating shaft; the handle comprises an operation part and a connecting part, the first rotating shaft is installed on the connecting part, the connecting part has a first stop protrusion and a second stop protrusion arranged at intervals; the handle has an open position and a folded position, when the first stop protrusion abuts against the stop pin, the handle is in the folded position; when the second stop protrusion abuts against the stop pin, the handle is in the open position. The first stop protrusion and the second stop protrusion cooperate with the stop pin respectively, limiting the rotating angle of the handle, and improving the operation safety of the extractor.

[0012] In one embodiment, the outer wall of the stop pin is provided with a damping rubber pad, and the damping rubber pad is in contact with the connecting part. The damping rubber pad can increase the friction when the handle rotates, and reduce the situation that the equipment is damaged due to high speed when the handle is opened or folded.

[0013] In one embodiment, the extractor further comprises a second reset member connected between the handle and the base, and the second reset member is used to drive the operation part away from the base.

DETAILED DESCRIPTION

[0035] For the purposes of the present application, the technical solutions and advantages are more clearly, the following embodiments combined with the drawings of the present application are further described in detail.

[0036] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be limiting on the present application. As used in the specification and the appended claims of the present application, the singular forms "a," "an," and "the" are intended to include the plural forms as well, e.g., "one or more," unless the context clearly indicates otherwise.

[0037] In the present specification, the reference to "one embodiment" or "a specific embodiment" or the like means that a specific feature, structure or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. The terms "include", "contain", "have" and their variants mean "including but not limited to", unless otherwise specifically emphasized.

[0038] In some related technologies, the unplugging aid is usually used in an environment where computer hardware devices need to be frequently plugged and unplugged, especially in environments such as servers and data centers. Due to the need for frequent replacement and maintenance of hardware devices, the unplugging aid assists in plugging and unplugging the device to be plugged by leverage, so that the operator can easily and safely pull out or insert the device to be plugged into the interface.

[0039] When the to-be-plugged device is inserted into the interface, the ejection aid is exposed outside the case, which is easy to cause misoperation of the operator, resulting in accidental ejection of the to-be-plugged device. Some to-be-plugged devices are non-hot-plug devices, and accidental ejection will cause the device to be unable to operate normally.

[0040] To solve the above problems, the application provides an ejection aid and electronic equipment, which can reduce the situation of misoperation of moving out the to-be-plugged device, and improve the safety of device operation and maintenance.

[0041] Figure 1 A structural schematic diagram of an ejection aid provided by an embodiment of the application in a locked state, Figure 2 An exploded view of an ejection aid provided by an embodiment of the application. As shown in Figure 1 and Figure 2 An ejection aid provided by an embodiment of the application includes a base 1 and a handle 2. The base 1 is used to connect the ejection aid to the to-be-plugged device. The handle 2 is rotationally connected to the base 1 around a first rotation shaft 3. The handle 2 is provided with a buckle 21 and a buckle locking mechanism 22. The buckle 21 is rotationally connected to the handle 2 around a second rotation shaft 4, and the buckle 21 has a first unlocking position and a first locking position. The base 1 is provided with a clamping groove 11. When the buckle 21 is located at the first locking position and the buckle 21 is clamped with the clamping groove 11, the handle 2 is locked with the base 1. The buckle locking mechanism 22 is rotationally installed on the handle 2, and the buckle locking mechanism 22 has a second unlocking position and a second locking position. When the buckle locking mechanism 22 is rotated to the second locking position, the buckle 21 is locked at the first locking position.

[0042] In the above embodiment, the to-be-plugged device can be a hard disk module. The handle 2 has an open position and a folded position. When the handle 2 is in the folded position, the handle 2 is clamped with the base 1. When the handle 2 is in the open position, the handle 2 has an included angle with the base 1.

[0043] Since the handle 2 is easy to be accidentally rotated when it is in the open position. Therefore, the handle 2 is rotated to the folded position, and the handle 2 is locked with the base 1. In this way, the situation that the to-be-plugged device is accidentally ejected due to misoperation of the operator rotating the handle 2 can be reduced. At the same time, when the buckle locking mechanism 22 is in the second locking position, the buckle 21 is prevented from rotating along the second rotation shaft 4, thereby realizing the function of secondary locking of the handle 2. The situation that the handle 2 is opened after the handle 2 and the base 1 are accidentally unlocked due to misoperation of the operator rotating the buckle 21 to the first unlocking position is avoided.

[0044] The buckle 21 and the buckle locking mechanism 22 improve the reliability of the ejection aid, thereby improving the safety of the device. In addition, when the handle 2 is in the folded position, the overall structure of the ejection aid is compact, and the space occupied is small.

[0045] Figure 3A partial cross-sectional view of a buckle locking mechanism of a puller provided in an embodiment of the present application in a second locking position, Figure 4 A partial cross-sectional view of a buckle locking mechanism of a puller provided in an embodiment of the present application in a second unlocking position. In combination with Figures 2 to 4 In an embodiment, the handle 2 has a through slot 23 in which the buckle 21 is arranged. The through slot 23 extends perpendicularly to the extension direction of the handle 2. The buckle 21 specifically has an L shape, comprising a button 211 and a connecting rod 212 connected to each other, the button 211 being located at one side of the L shape and the connecting rod 212 being located at the other side of the L shape. The second rotating shaft 4 is arranged between the button 211 and the connecting rod 212. The end of the connecting rod 212 away from the button 211 has a clamping hook 213 bent towards the inside of the L shape. The connecting rod 212 extends towards the base 1. The through slot 23 has a first side plate 231 and a second side plate 232 arranged opposite to each other, and the second rotating shaft 4 is connected to the first side plate 231 and the second side plate 232. It is worth noting that the space of the through slot 23 is large enough to allow the buckle 21 to rotate by a certain angle in the through slot 23 to realize the unlocking and locking actions.

[0046] Reference is made to Figure 3 Or Figure 4 In an embodiment, the clamping groove 11 has a 90° folded edge 111. When the buckle 21 is clamped with the clamping groove 11, the folded edge 111 is parallel to the connecting rod 212, the clamping hook 213 is clamped with the folded edge 111, and the handle 2 is parallel to the base 1.

[0047] In an embodiment, the button 211 is provided with a first recess 2111 on the side facing the base 1. The through slot 23 is provided with a fixed plate 24 fixedly connected to the handle 2 as an integral structure. The fixed plate 24 is arranged opposite to the button 211 along the through direction of the through slot 23, and the fixed plate 24 is provided with a second recess 241 on the side away from the base 1, and the first recess 2111 and the second recess 241 are arranged opposite to each other. The puller further comprises a first reset member 5, which specifically can be a spring, one end of the spring being arranged in the first recess 2111 and the other end being arranged in the second recess 241. The first reset member 5 is used to drive the buckle 21 to rotate from the first unlocking position to the first locking position. The first locking position is the initial position, and the buckle 21 is rotated by pressing the button 211, at which time the first reset member 5 is compressed. After the clamping hook 213 is disengaged from the clamping groove 11, the button 211 is released, and the first reset member 5 automatically expands to drive the buckle 21 to automatically rotate in the opposite direction and return to the initial position.

[0048] Reference is made to Figures 2 to 4In an embodiment, the snap-locking mechanism 22 comprises a locking pin 221 and a locking plate 222, the locking plate 222 is fixedly installed on the locking pin 221 near one end of the base 1, the locking plate 222 has a limiting protrusion 2221, and the axial direction of the locking pin 221 is perpendicular to the second rotating shaft 4. Specifically, the locking plate 222 can be close to an oval shape, and the locking pin 221 is a cylinder. The limiting protrusion 2221 can be located at the two end positions of the long axis of the oval locking plate 222. The side of the connecting rod 212 away from the clasp 213 is an abutting surface 2121. When the locking pin 221 is rotated to the second locking position, the limiting protrusion 2221 abuts against the abutting surface 2121, thereby limiting the rotation of the snap 21. When the locking pin 221 is rotated to the second unlocking position, the limiting protrusion 2221 is away from the abutting surface 2121, and the locking plate 222 is spaced apart from the connecting rod 212 by a preset distance. At this time, the snap 21 has enough space to rotate, thereby performing the unlocking operation of the snap 21.

[0049] It is worth noting that when the locking pin 221 is rotated to the second locking position, the limiting protrusion 2221 can also not be in contact with the abutting surface 2121. The limiting protrusion 2221 and the abutting surface 2121 have a gap, and the gap is not enough for the clasp 213 to disengage from the clamping groove 11, and the same effect of limiting the rotation of the snap 21 can be achieved.

[0050] In an embodiment, the handle 2 has a mounting hole 25. The snap-locking mechanism 22 is embedded in the mounting hole 25, and the end of the locking pin 221 away from the locking plate 222 has a first surface 2211 parallel to the locking plate 222. The first surface 2211 is provided with a groove 22111 for inserting an unlocking tool. The unlocking tool can be, for example, a screwdriver. Insert the screwdriver into the groove and rotate the locking pin 221 clockwise or counterclockwise, and the locking pin 221 drives the locking plate 222 to rotate, which can switch between the second unlocking position and the second locking position.

[0051] Figure 5 A cross-sectional view of a locking pin and a limiting block provided for an embodiment of the present application is shown in FIG. 6, which is combined with Figures 2 to 5 In an embodiment, two limiting blocks 251 are arranged in the mounting hole 25 of the handle 2, and the two limiting blocks 251 are arranged at an angle of 90°, i.e., the two limiting blocks 251 are located on the same circumference, and the central angle corresponding to the two limiting blocks 251 is 90°. The limiting block 251 is used to limit the rotation angle of the locking pin 221. The outer wall of the locking pin 221 is provided with two stop protrusions 2212, and the two stop protrusions 2212 are arranged at an angle of 180°, i.e., the two stop protrusions 2212 are located on the same straight line. When the locking pin 221 is rotated, the stop protrusion 2212 abuts against the limiting block 251, and the snap-locking mechanism 22 is located at the second unlocking position or the second locking position.

[0052] In an embodiment, the first surface 2211 can further be provided with a first mark point 22112, and the handle 2 can be provided with a second mark point 22113. When the first mark point 22112 and the second mark point 22113 are aligned, the buckle locking mechanism 22 is in the second locking position, and the buckle 21 is in the locked state. The first mark point and the second mark point can enable an operator to visually see the position of the buckle locking mechanism 22 and determine whether the buckle 21 is in the locked state, thereby improving the accuracy of operation.

[0053] Figure 6 A structure schematic view of the extractor in an open position according to an embodiment of the present application, Figure 7 A structure schematic view of the extractor in a folded position according to an embodiment of the present application. In combination with Figure 2 、 Figure 6 and Figure 7 In an embodiment, the extractor further comprises a stop pin 6 for limiting the rotation angle of the handle 2. The base 1 comprises a third side plate 12 and a fourth side plate 13 arranged oppositely. The axial direction of the stop pin 6 is parallel to the first rotation shaft 3. The handle 2 comprises an operation part 26 and a connecting part 27. The connecting part 27 is substantially circular, and the operation part 26 is elongated. One end of the operation part 26 is connected to the connecting part 27. The stop pin 6, the first rotation shaft 3 and the connecting part 27 are all mounted between the third side plate 12 and the fourth side plate 13. Meanwhile, the first rotation shaft 3 is arranged in the through hole of the connecting part 27. The connecting part 27 has a first stop protrusion 271 and a second stop protrusion 272 arranged at intervals on the outer wall parallel to the first rotation shaft 3. When the first stop protrusion 271 is abutted against the stop pin 6 by rotating the handle 2, the handle 2 is in the folded position, and the buckle 21 is engaged with the buckle groove 11. The buckle 21 is unlocked by rotating, and the handle 2 is rotated until the second stop protrusion 272 is abutted against the stop pin 6, and the handle 2 is in the open position. The stop pin 6, the first stop protrusion 271 and the second stop protrusion 272 limit the rotation of the handle 2 within an angle range. The first stop protrusion 271 can avoid the handle 2 from hitting the base 1 due to excessive rotation, and the second stop protrusion 272 can avoid the handle 2 from being opened too wide, thereby improving the safety and ease of use.

[0054] Continuing to refer to Figure 2In one embodiment, the outer wall of the stop pin 6 is provided with a damping rubber pad 61, which is in contact with the connecting part 27. The damping rubber pad 61 is flexible and can be deformed when subjected to pressure. The gap between the connecting part 27 and the stop pin 6 can be slightly smaller than the thickness of the damping rubber pad 61. When assembling the extractor, the damping rubber pad 61 is in a state of being compressed by the stop pin 6 and the connecting part 27 and slightly deformed. When rotating the handle 2 around the first rotating shaft 3, the damping rubber pad 61 is compressed by the stop pin 6 and the connecting part 27, thereby increasing the friction when the handle 2 is rotated, which can slow down the speed of opening and closing the handle 2, thereby reducing the impact of the handle 2 on the base 1 or the equipment when opening and closing.

[0055] Please refer to Figure 7 In one embodiment, the extractor further comprises a second reset member 7 connected between the handle 2 and the base 1, which is used to drive the operating part 26 away from the base 1, so that the handle 2 reaches the open position. Specifically, the second reset member 7 can also be a spring. The inner side of the third side plate 12 or the fourth side plate 13 of the base 1 is provided with a convex bridge 14, and one end of the spring can be connected to the convex bridge 14. The other end is connected to the connecting part 27 of the handle 2, specifically to the second stop protrusion 272. The second stop protrusion 272 and the convex bridge 14 are respectively located on the two sides of the stop pin 6. When rotating the handle 2 from the open position to the folded position, the second stop protrusion 272 gradually moves away from the stop pin 6, and the second reset member 7 is stretched. After the handle 2 is unlocked, the second reset member 7 is released to shrink and recover, driving the handle 2 to rotate to the open position.

[0056] In one embodiment, the handle 2 further comprises a clamping part 28, which comprises a first clamping surface 281 and a second clamping surface 282 arranged oppositely, and the first clamping surface 281 and the second clamping surface 282 are spaced apart by a predetermined distance. The first clamping surface 281 is used to assist the insertion of the to-be-plugged device when abutting against the structural block 101 of the cabinet 100, and the second clamping surface 282 is used to assist the extraction of the to-be-plugged device when abutting against the structural block 101 of the cabinet 100. The clamping part 28 is in the shape of a groove, and the opening width of the groove is greater than the width of the groove bottom, which facilitates the butt joint of the clamping part 28 and the structural block 101. The above-mentioned structural block 101 refers to the structural member on the cabinet 100 that provides a lever fulcrum for the extractor.

[0057] Figure 8 Another extractor provided by the embodiments of the present application is shown in the structure schematic view in the folded position, as shown in Figure 8In one embodiment, along the extension direction of the handle 2, the connecting portion 27 of the handle 2 is located at one end of the operating portion 26, the vertical distance A between the other end of the operating portion 26 and the first rotating shaft 3, and the vertical distance B between the farthest end of the clamping portion 28 and the first rotating shaft 3 satisfy A:B=10:1. When the handle 2 satisfies the above ratio, 10N of force can be applied to the farthest end position C of the operating portion 26, so that the farthest clamping position D of the clamping portion 28 can generate 100N of overturning force, so that the extractor is more labor-saving when inserting and pulling the device.

[0058] Figure 9 An exploded view of an extractor and a device to be inserted and pulled provided by an embodiment of the present application, and on the other hand, Figure 10 A structural view of an extractor, a device to be inserted and pulled, and a case provided by an embodiment of the present application, Figure 11 A partial schematic view of an electronic device provided by an embodiment of the present application. As Figures 9 to 11 shown, the electronic device provided by an embodiment of the present application further comprises a case 100, a device to be inserted and pulled 200, and at least one extractor 300 in any of the above embodiments, at least one extractor 300 is installed on the device to be inserted and pulled 200, and the device to be inserted and pulled 200 is detachably connected to the case 100.

[0059] The electronic device can be a server, and the device to be inserted and pulled 200 can be a hard disk module. The extractor 300 can be two, and the two extractors 300 are symmetrically installed on both sides of the bracket of the hard disk module. The extractor 300 is used to insert the hard disk module into the case 100 or pull the hard disk module out of the case 100. The electronic device using the extractor in some of the above embodiments realizes the double locking of the handle 2 and the base 1 by setting the buckle 21 and the buckle locking mechanism 22.
