[0029] Embodiment 1

[0030] like Figure 1 As shown, the present application provides a pull-out aid, comprising:

[0031] An operating handle 10, the operating handle 10 is rotatably connected to the chassis;

[0032] A booster 11, the booster 11 is disposed on the operating handle 10;

[0033] When the operating handle 10 rotates in a first direction, the booster 11 is used to push the blade 20 into the chassis through the blade force-bearing portion 21 , and when the operating handle 10 rotates in a second direction, the booster 11 is used to push the blade 20 out of the chassis through the blade force-bearing portion 21 .

[0034] Optionally, a connection pair is provided on the end of the operating handle 10 connected to the chassis, and the operating handle 10 is rotatably connected to the chassis through the connection pair. In addition, a booster 11 is provided on the end of the operating handle 10 connected to the chassis near the connector, and the booster 11 is a protrusion that protrudes obliquely toward the blade 20. The booster 11 is used to contact the blade server and apply plugging and unplugging force to the blade server.

[0035] Optionally, the protruding length of the booster 11 is less than the length of the operating handle 10, and the booster 11 and the operating handle 10 can rotate synchronously through the above-mentioned rotation connection with the chassis. The booster 11 and the operating handle 10 are integrally formed to form a labor-saving lever. The booster 11 and the operating handle 10 can amplify the operating force applied by the operator to the operating handle 10 by N times and transmit it to the booster 11, wherein the amplification factor N is the ratio of the length of the force arm on the operating handle 10 to the length of the booster 11, and N≥1.

[0036] Optionally, a roller is provided at the end of the booster 11 that contacts the blade 20, and the booster 11 contacts the blade force-bearing portion 21 on the blade 20 through the roller and applies an operating force, so that the force generated by the relative sliding of the booster 11 and the blade force-bearing portion 21 on the blade 20 during the insertion and removal operation of the blade 20 is a rolling friction force, which has the technical effect of reducing friction and effort, and at the same time reducing the wear of the booster 11 and the blade force-bearing portion 21 on the blade 20.

[0037] Optional, such as Figure 3 As shown, when the operator inserts the blade 20 and the blade 20 is inserted to about 15 mm from the bottom, the thrust member 11 acts on the blade force-bearing portion 21 of the blade 20 close to the inner surface of the front panel of the blade 20, resisting the blade 20 so that the blade 20 cannot be further inserted.

[0038] Optional, such as Figure 4 As shown, the operator manually pulls the puller, so that the puller rotates around the rotating connection pair in the first direction, and the booster 11 also rotates synchronously in the first direction. The first direction is the direction in which the handle 10 is close to the connector of the blade 20. After rotating at a certain angle, the roller at one end of the booster 11 in contact with the blade 20 contacts the inner surface of the blade force-bearing part of the blade 20 away from the front panel of the blade 20. As the puller continues to rotate in the first direction, the roller pushes the blade 20 to continue to be inserted into the connector direction through the labor-saving effect of the puller, until the rear connector of the blade 20 engages with the connector on the chassis, thereby achieving the technical effect of helping the operator to easily insert the blade.

[0039] Optionally, the operator pulls the puller outward to make the puller rotate around the rotating connection pair in the second direction, and the booster 11 also rotates synchronously in the second direction, and the second direction is the direction to move the handle 10 away from the connector of the blade 20. After a certain angle is selected, the roller at one end of the booster 11 in contact with the blade 20 contacts the inner surface of the blade force-bearing part of the blade 20 close to the front panel of the blade 20. At this time, by virtue of the force amplification effect of the puller, the blade 20 is pushed outward by the roller until the rear connector of the blade 20 is completely disconnected from the connector on the chassis, thereby saving effort when pulling out the blade. At this time, the operator can manually pull the blade 20 out of the chassis.

[0040] Furthermore, the present application provides an extraction aid, further comprising:

[0041] The elastic member 12 is used to provide the ejection aid with a force to maintain a preset position without the action of an external force.

[0042] Optionally, the elastic member 12 has a minimum force when the ejection aid is at a maximum position in the first direction, and has a maximum force when the ejection aid is at a maximum position in the second direction, and the minimum force is sufficient to keep the operating handle 10 in a horizontal state when there is no external force.

[0043] Optional, such as Figure 3 As shown, when the blade 20 is not inserted and the blade 20 just contacts the extraction aid but no operating force is applied to the operating handle 10, the extraction aid body is rebounded to the maximum angle under the action of the elastic member 12, and the operating handle 10 is approximately in a horizontal state, thereby ensuring that the insertion port of the blade 20 is unobstructed.

[0044] Optional, such as Figure 6 As shown, when the blade 20 needs to be pulled out of the chassis, the pull-out aid is rotated along the second direction by the force of the elastic member 12 until the roller contacts the inner surface of the blade force-bearing part of the blade 20 close to the front panel of the blade 20. At this time, the operating handle 10 is at a certain angle to the front panel of the blade 20, which is convenient for the operator to pull it.

[0045] Furthermore, the present application provides an extraction aid, further comprising:

[0046] The rotating shaft 22 is fixed to the chassis and is used for rotatingly connecting the operating handle 10 .

[0047] Optionally, the pull-out aid is fixedly connected to the chassis via a rotating shaft 22. For example, Figure 2 As shown, the rotating shaft 22 is fixed to the front of the chassis by two screws, and the pull-out aid, the rotating shaft 22 and the chassis form a rotating pair to achieve a rotation connection between the pull-out aid and the chassis.

[0048] Optionally, the elastic member 12 is sleeved on the rotating shaft 22 and is in a forced deformation state under the action of the ejector and the chassis, so that the ejector has a technical effect of automatically popping out.

[0049] Further, such as Figure 5 As shown, the present application provides an auxiliary puller, further comprising:

[0050] The lock buckle 13 is selectively engaged with the blade 20 through the blade engaging portion.

[0051] Optionally, when the blade 20 is fully inserted into the chassis, the rear connector of the blade 20 is firmly engaged with the connector on the chassis, the puller reaches the maximum stroke along the first direction, and the lock 13 at one end of the puller operating handle away from the rotating pair is engaged with the blade force-bearing part on the blade 20, thereby fixing the puller and the pusher on the puller. The puller cannot pop out, and the blade 20 is firmly fixed on the chassis.

[0052] Optional, such as Figure 6 As shown, when the blade 20 needs to be pulled out, the lock 13 is unlocked, and the pull-out aid is subjected to the force of the elastic member 12, rotates in the second direction, and the operating handle 10 pops out. After the pull-out aid rotates a certain angle in the second direction, the roller contacts the front side of the blade force-bearing portion 21 on the blade 20, and the pull-out aid cannot continue to rotate. At this time, the operator can pull the pull-out aid outward, and by virtue of the force amplification effect of the pull-out aid, the roller pushes the blade 20 outward, so that pulling out the blade also has a labor-saving effect.

[0053] Optionally, when the extraction aid reaches the maximum stroke along the second direction, that is, the operating handle 10 moves to the above-mentioned horizontal position, the connector on the blade 20 has been disconnected from the connector of the chassis, and the operator can manually take out the blade 20 to complete the extraction of the blade 20.

[0054] Further, the blade force-bearing portion 21 is a groove or a protrusion;

[0055] Optionally, the blade force-bearing portion 21 is a groove with a specific shape. Optionally, the width of the groove is adapted to the width of the booster 11, and the two are clearance-matched to ensure smooth movement of the booster 11 in the groove. In addition, the groove provides a guide for the sliding installation of the blade 20 to ensure the correct engagement of the connector on the blade 20 with the connector on the chassis.

[0056] Optionally, after the blade 20 is connected to the chassis, the cooperation between the groove and the booster 11 together with the connector forms a fixed position of the blade 20, ensuring that the blade 20 is firmly installed.

[0057] Furthermore, the blade engaging portion is a groove or a protrusion that can engage with the lock buckle 13 .

[0058] Optionally, the blade clamping portion is a groove or a protrusion for clamping with the lock buckle 13. The groove or protrusion of the blade clamping portion is adapted to the shape of the lock buckle 13, and the groove or protrusion of the blade clamping portion is in a clearance fit state after being clamped with the lock buckle 13, which facilitates the unlocking of the lock buckle 13.

[0059] Embodiment 2

[0060] The present application also provides a chassis, and part or all of the features of an extraction aid provided by the present application are applied to the above-mentioned chassis.

[0061] Specifically, the above-mentioned chassis is provided with M extraction aids, and the chassis can be inserted with K blades 20, and the number of extraction aids M≤K, thereby achieving the technical effect of reducing costs, saving chassis space, and improving blade extraction efficiency.

[0062] Embodiment 3

[0063] The present application also provides a blade server, and the above-mentioned blade server is provided with a blade force-bearing part and / or a blade clamping part that are compatible with the pull-out aid provided by the present application.

[0064] Optionally, the blade force-bearing portion 21 on the blade server has similar shape features to the blade force-bearing portion 21 on the above-mentioned blade 20. Exemplarily, the blade force-bearing portion on the blade server is slightly larger than the outer dimensions of the booster 11, and ensures that the blade server is firmly connected when the puller is at the maximum position in the first direction, and the blade server is completely disconnected from the chassis when the puller is at the maximum position in the second direction. The blade clamping portion is a groove or protrusion for engaging with the lock 13. Among them, the groove or protrusion of the blade clamping portion is adapted to the shape of the lock 13.

[0065] In summary, the operating handle is rotatably connected to the chassis; the booster is deployed on the operating handle; when the operating handle rotates in a first direction, the booster is used to push the blade into the chassis through the blade force-bearing part, and when the operating handle rotates in a second direction, the booster is used to push the blade out of the chassis through the blade force-bearing part, thereby realizing labor-saving insertion and removal of the blade. In the scenario with few chassis and many blades, the use of the puller can be reduced, thereby achieving the technical effect of reducing the use of the puller, reducing costs and chassis space occupancy, and facilitating mass production.
