Description

Technical Field

[0001] This application relates to a pull-out aid, and more particularly to a damped pull-out aid. This application also relates to a server bracket including the pull-out aid. Background Technology

[0002] A puller (also known as a pusher / puller device) is a device that assists a user in inserting a first object into or pulling out a second object.

[0003] A common application of pull-out aids is in servers, primarily to improve the ease of plugging and unplugging server modules. However, during the process of removing a server module from its rack, the module may be suddenly released or ejected due to rapid tripping, potentially damaging the module, injuring the operator, or damaging other internal modules. Therefore, pull-out aids not only need to assist in removing the server module but also need to provide appropriate braking to ensure that the server is not damaged during removal, that the stability of the entire system is not compromised, or that the operator is not injured. However, traditional pull-out aids (such as those with a dual-pivot design) struggle to meet all these requirements. Utility Model Content

[0123] To further illustrate the principles and structure of this application, some embodiments of this application will now be described in detail with reference to the accompanying drawings. However, it should be understood that the embodiments described are merely exemplary and this application should not be construed as limited to the embodiments set forth herein.

[0124] Furthermore, for ease of understanding and description, this document uses descriptions of directions such as front and back, left and right, and up and down. These directions are based on the orientation of the puller during normal use. For example, the direction in which the object is pulled out during the pull-out process is considered front, while the direction in which the object is inserted during the push-out process is considered rear. Left, right, up, and down are thus determined. It should be understood that this disclosure is not limited to these orientations but can be adjusted according to actual circumstances.

[0125] Figures 1 to 9 Various views illustrate the pull-out aid 100 of this application. The pull-out aid 100 includes a base plate 140, a handle 110, and a claw 160. The handle 110 and the claw 160 are pivotally connected to the base plate 140. A locking post 162 is provided on the surface of the claw 160 facing the handle 110. The locking post 162 is configured to engage with the handle 110 such that the claw 160 and the handle 110 pivot in the same direction. Specifically, during the pull-out process of the pull-out aid 100, the claw 160 rotates in a first direction, and the locking post 162 contacts the handle 110 and pushes the handle 110 to rotate in the first direction; during the pushing process of the pull-out aid 100, the handle 110 rotates in a second direction, and when the handle 110 contacts the locking post 162, the handle 110 pushes the locking post 162, thereby pushing the claw 160 to rotate in the second direction.

[0126] like Figure 1-9 As shown, the handle 110 may include a handle 111 and a connecting rod 112. The connecting rod 112 may include a first connecting rod 1120 and a second connecting rod 1130, which are located on both sides of the handle 111, and one end of the first connecting rod 1120 (e.g., the upper end shown in the figure) and one end of the second connecting rod 1130 (e.g., the upper end shown in the figure) are connected via the handle 111. Additionally, the pull-out aid 100 may also include a cover 130, which may include a first cover 131 and a second cover 132. The aforementioned base plate 140 may include a first base plate 141 and a second base plate 142. The first cover 131 and the first base plate 141 are mutually connected to receive the other end of the first connecting rod 1120 (e.g., the lower end shown in the figure); similarly, the second cover 132 and the second base plate 142 are mutually connected to receive the other end of the second connecting rod 1130 (e.g., the lower end shown in the figure). For the sake of simplicity, the following description will take one side of the structure of the pull-out aid 100 (for example, the left side structure shown in the figure) as an example.

[0127] like Figure 9 As shown, the upper end of the first connecting rod 1120 is provided with a fixing hole 1211; correspondingly, one end of the handle 111 (for example, the left end shown in the figure) is also provided with a fixing hole 1111; the fixing member 1122 is inserted into the fixing hole 1211 and the fixing hole 1111 to fix the first connecting rod 1120 to the handle 111. Optionally, the upper end of the first connecting rod 1120 is also provided with a through hole 1123 (two are shown exemplarily in the figure); correspondingly, the left end of the handle 111 is provided with a protrusion 1112; when the upper end is fixed to the left end of the handle 111 by the fixing member 1122, the protrusion 1112 also fits in the through hole 1123 to further stabilize the connection between the first connecting rod 1120 and the handle 111.

[0128] like Figure 7-9As shown, at the lower end of the first connecting rod 1120, a first cover 131 and a first substrate 141 are respectively disposed on the left and right sides of the first connecting rod 1120. The first cover 131 is provided with a fixing hole 1311; correspondingly, the first substrate 141 is also provided with a fixing hole 1411. Optionally, the fixing holes 1311 and 1411 can be hexagonal, but this application is not limited thereto. The pull-out aid 100 includes a mounting post 101, which passes through the fixing holes 1311 and 1411 to connect the first cover 131 and the first substrate 141 together and to subsequently install the first cover 131 and the first substrate 141 to the first object of the pull-out aid 100, thereby helping the user to pull the first object out of or insert it into the second object. The first object can be a server's reservoir and pumping unit (RPU); the second object can be a server bracket. Specifically, the mounting post 101 can be formed into a post shape that is thinner at both ends and thicker in the middle. The thinner ends can be inserted into the fixing holes 1311 and 1411 respectively in a shape-fitting manner, while the thicker middle part can serve to space the first cover 131 and the first substrate 141 in the left-right direction, thereby defining a receiving cavity 106 (marked in the subsequent cross-sectional view) between the first cover 131 and the first substrate 141.

[0129] Optionally, both the first cover 131 and the first substrate 141 can be square; the first cover 131 and the first substrate 141 have fixing holes 1311 and 1411 respectively at the corners of the planes formed by the vertical and horizontal directions and the front and back directions, and can be at a certain corner (e.g. Figure 9 The corner portions 1312 and 1412 shown do not have fixing holes 1311 and 1411. The lower end of the first connecting rod 1120 is received in a receiving cavity 106 defined by the first cover 131 and the first base plate 141, and a portion of the lower end can protrude from the corner portions 1312 and 1412 out of the receiving cavity 106. Preferably, the corner portions are rounded to avoid obstructing the pull-out / push-out process.

[0130] In addition, such as Figure 9As shown, the pull-out aid 100 may further include an actuating element 150, and both the actuating element 150 and the aforementioned claw 160 may be at least partially disposed in the receiving cavity 106. The first substrate 141 may have three connecting holes 1413 in its intermediate region. Correspondingly, the first connecting rod 1120 has a pivot hole 1124 at its lower end; the actuating element 150 has a pivot hole 151; and the claw 160 has a pivot hole 161. The pull-out aid 100 may further include a first connecting post 102, a second connecting post 103, and a third connecting post 104. Specifically, the first connecting post 102 passes through the connecting hole 1413 and the pivot hole 1124 to pivotally connect the first connecting rod 1120 to the first substrate 141, and the first connecting post 102 is the pivot axis of the first connecting rod 1120. Similarly, the second connecting post 103 passes through the connecting hole 1413 and the pivot hole 151 to pivotally connect the actuator 150 to the first substrate 141, and the second connecting post 103 is the pivot axis of the actuator 150; the third connecting post 104 passes through the connecting hole 1413 and the pivot hole 161 to pivotally connect the claw 160 to the first substrate 141, and the third connecting post 104 is the pivot axis of the claw 160.

[0131] Optionally, the first cover 131 may have three connecting holes 1313 corresponding to the connecting holes 1413 in its middle region. The first connecting post 102, the second connecting post 103 and the third connecting post 104 may also pass through the connecting holes 1313, so that the first connecting rod 1120, the actuating member 150 and the claw 160 can be pivotally connected to the first cover 131 and the first base plate 141 through the first connecting post 102, the second connecting post 103 and the third connecting post 104 respectively.

[0132] Reference Figure 9 And combined with subsequent partial stereoscopic images (e.g.) Figure 12D The pull-out aid 100 may further include an elastic element 180, which can be sleeved on the second connecting post 103 and located on the side of the actuating member 150 facing the claw 160, so that the elastic force of the elastic element 180 can act on the actuating member 150. Optionally, the elastic element 180 may be a torsion spring. Alternatively, the pull-out aid 100 may further include a sleeve 170, through which the elastic element 180 is installed to the actuating member 150, so that the elastic force of the elastic element 180 can also act on the actuating member 150.

[0133] In addition, refer to Figure 9 And combined with subsequent partial stereoscopic images (e.g.) Figure 12DThe puller 100 may further include a washer 190, which can be sleeved on the third connecting post 104 and located on the side of the claw 160 opposite to the handle 110 (specifically, on the side opposite to the lower end of the connecting rod 112), that is, the washer 190 is located between the claw 160 and the first cover 131; that is, the washer 190 is disposed on the side of the claw 160 opposite to the claw post 162. Optionally, the washer 190 may be a corrugated washer, and two washers may be provided. Alternatively, the first connecting post 102 may also be sleeved with a washer 190, which may be located on the side of the first connecting rod 1120 opposite to the claw 160, that is, between the handle 110 (or the first connecting rod 1120) and the first base plate 141. The corrugated washers fitted on the connecting posts 104 and 102 can dampen the pivoting of the pawl 160 and the first connecting rod 1120 through their elastic deformation.

[0134] Alternatively, similar to mounting post 101, the first connecting post 102, the second connecting post 103, and the third connecting post 104 may also be formed into column shapes with inconsistent thicknesses in order to fit with the shapes of pivot holes, sleeves, and washers.

[0135] Continue to refer to Figure 9 And combined with subsequent partial stereoscopic images (e.g.) Figure 12D-12E The first connecting rod 1120 may be formed in a cam shape at its lower end. The puller 100 may include a contact portion 1125, a protrusion 1126, and a limiting portion 1127 at the lower end of the cam shape. The overall outline of the contact portion 1125, the protrusion 1126, and the limiting portion 1127 may be approximately "W" shaped. In addition, the actuating member 150 may be substantially L-shaped, with the aforementioned pivot hole 151 located approximately at the intersection of the two legs of the L-shape; the actuating member 150 may also include a receiving recess 152 approximately near the intersection, in which the locking pin 162 of the pawl 160 may engage. Furthermore, the pawl 160 may also include a capturing portion 163, in which the first connecting pin (i.e., the pivot shaft) 102 may engage.

[0136] like Figure 1-9As shown, the pull-out aid 100 is basically symmetrical from left to right. Therefore, the right side structure of the pull-out aid 100 can refer to the left side structure described above. Alternatively, the arrangement of the cover 130 and the base plate 140 may not follow the principle of left-right symmetry. That is, in the right side structure, at the lower end of the second connecting rod 1130, the second cover 132 can be located on the left side of the lower end, while the second base plate 142 can be located on the right side of the lower end. This arrangement helps to simplify the manufacturing of the cover 130 and the base plate 140 because the positions of the fixing holes and connecting holes on the cover and the base plate are not arbitrarily set, but need to cooperate with other components of the pull-out aid 100. If the second cover 132 is located on the right side and the second base plate 142 is located on the left side for symmetry, then the second cover 132 and the second base plate 142 need to be re-molded.

[0137] like Figure 1-9 As shown, the pull-out aid 100 may further include a fastening assembly 105, which may be, for example, the applicant's standard 1 / 4 turn fastening assembly. The handle 111 may include a recess 1113 at its intermediate location for engaging with the fastening assembly 105 to mount the pull-out aid 100 to a first object. The fastening assembly 105 may include a fastener 1051 and a locking ratchet 1053. The fastener 1051 may include a head 10511 and a rod portion 10512. The head 10511 and the rod portion 10512 may be integrally formed. Specifically, the rod portion 10512 is inserted into the recess 1113 from the front side of the handle 111 and engages with the locking ratchet 1053 located at the rear side of the handle 111 to lock it in place, ensuring that the fastening assembly 105 does not loosen itself after connection. Preferably, the fastening assembly 105 may further include a gasket 1054 located between the handle 111 and the locking ratchet 1053 to further enhance the stability and reliability of the connection.

[0138] Optionally, the handle 111 is made of zinc alloy, and the connecting rod 112, cover 130, base plate 140, actuator 150, claw 160, elastic element 180 and washer 190 are all made of stainless steel; however, this application is not limited thereto.

[0139] Optionally, the thickness of the connecting rod 112 (i.e., the dimension in the left-right direction) can be 3 mm, which not only makes it easy to process and form into various shapes, but also maintains good strength and durability, and can withstand greater forces. However, it should be understood that this application is not limited thereto.

[0140] Reference Figure 10 The pull-out aid 100 may also include an actuator 400 through which the first object can be connected to the second object. The actuator 400 may, for example, be a connector from CEJN, such as the quick-disconnect connector 2X CEJN QD. Figure 10As shown, the actuator 400 has a separable cylindrical portion 410 and a piston portion 420, the cylindrical portion 410 being attached to a second object and the piston portion 420 being attached to a first object. The actuator 400 is configured to provide a force to the first object, the direction of which is consistent with the direction of the piston portion 420 away from the cylindrical portion 410. During the process of pulling the first object out of the second object, the force of the actuator 400 acts as a pushing force on the first object, assisting it in moving away from the second object; while during the process of inserting the first object into the second object, the force of the actuator 400 acts as a resistance force on the first object, preventing it from entering the second object.

[0141] In such Figure 10 In the example shown, when the cylinder 410 is disconnected from the piston 420, the minimum distance between them is, for example, 177.8 mm; when the cylinder 410 and piston 420 are joined together, the minimum distance between them is, for example, 145.1 mm. That is, the relative stroke between the cylinder 410 and piston 420 is 32.7 mm. Specifically, during the insertion of the first object, the cylinder 410 and piston 420 first move from being completely separated to a minimum distance of 177.8 mm when they are disconnected. During this process, the actuator 400 does not exert any force on the first object. Next, the actuator 400 has a pre-stroke of 7.4 mm (i.e., the distance between the cylinder 410 and piston 420 is shortened to 170.4 mm) to ensure alignment of the cylinder 410 and piston 420 before the actuator is fully connected. During this process, the actuator 400 begins to exert a force (or resistance) on the first object. Then, the piston 420 is inserted into the cylinder 410 until the minimum distance between them reaches 145.1 mm, thus connecting the first and second objects. During this process, the actuator 400 applies a force (or resistance) to the first object. For example, to connect a first object weighing 9.0 kg to a second object, a matching force of 60 kgf is required between the cylinder 410 and piston 420.

[0142] Similarly, during the pulling out of the first object, the actuator 400, which is in a connected state, applies a force (or thrust) to the first object; when the actuator 400 gradually moves until the cylinder 410 and the piston 420 are completely separated, the thrust of the actuator 400 on the first object disappears.

[0143] Figure 11A-11F The three-dimensional sectional view schematically illustrates the process by which the puller 100 of this application pulls the first object 200 out of the second object 300. Figure 11G-11HA perspective sectional view schematically illustrates the process by which the puller 100 of this application assists in inserting the first object 200 into the second object 300. During the pull-out process, the handle 110 changes from a folded position to an operating position, and then back to a fixed position; during the push-out process, the handle 110 changes from a fixed position to an operating position, and then back to a folded position. The folded position refers to the handle 110 being locked onto the first object 200, such as... Figure 11A As shown. The operating position refers to the ability of handle 110 to rotate within a certain angle range, such as... Figure 11B-11E As shown in 11G-11H. A fixed position means that when handle 110 is rotated clockwise to a certain angle, it cannot be rotated further or returned to its original position, as shown in Figure 11G-11H. Figure 11F As shown. During the extraction process, the pushing end 1128 of the handle 110 of the extraction aid 100 pushes the second object 300, thereby causing the limiting groove 310 of the second object 300 to drive the limiting end 164 of the claw 160 of the extraction aid 100, causing the claw 160 to pivot, and the locking pin 162 of the claw 160 pushes the handle 110 to rotate clockwise. During the pushing process, the second object 300 touches the trigger end 154 of the trigger 150 of the extraction aid 100, causing the trigger to rotate counterclockwise, thereby causing the handle 110 to rotate counterclockwise, and pushing the locking pin 162 to make the claw 160 rotate counterclockwise. The limiting end 164 abuts against the limiting groove 310 to cooperate with the limiting groove 310.

[0144] The following reference Figure 12A-17D The specific description of the extraction aid 100 describes the extraction process in which the extraction aid 100 assists the user in pulling the first object 200 out of the second object 300.

[0145] like Figures 12A-12E As shown, the pull-out aid 100 is locked to the first object 200 by a fastening assembly 105. The locking ratchet 1053 of the fastening assembly 105 can be mounted on the first object 200, specifically located at the upper edge of the first panel 210 of the first object 200. Additionally, mounting holes can be provided on both the left and right sides of the first object 200 to secure the pull-out aid 100 to the first object 200. Specifically, as... Figure 12A As shown, the second panel 220 of the first object 200 has a mounting hole 221, which corresponds to the fixing hole on the cover and the base plate of the puller 100. The fixing member (e.g., M3 screw) passes through the mounting hole and the fixing hole in sequence (or the mounting post 101 set in the fixing hole as described above) to fix the second panel 220 to the first cover 131. That is, the first cover 131 is located on the right side of the second panel 220 (or it can be understood that the first cover 131 is located on the inner side of the second panel 220). In this way, the puller 100 can be at least partially covered, thereby improving the overall appearance and aesthetics.

[0146] Optionally, the fastener may also pass through one of the mounting hole 221 of the second panel 220 and the connecting hole (or connecting post disposed in the connecting hole as described above) of the puller 100 to secure the second panel 220 to the first cover 131. Optionally, the mounting post and connecting post for cooperating with the fastener are hollow posts with internal threads so that the fastener passes through and is threaded thereto.

[0147] exist Figures 12A-12E When the fastening assembly 105 is in the locked state, the handle 110 is in the folded position, that is, the handle 111 is fastened to the first panel 210 of the first object 200. In this locked state, one end (hereinafter referred to as the abutting end) 153 of the L-shaped actuating member 150 protrudes from the notch 1414 provided on the upper surface of the first substrate 141, and the other end (hereinafter referred to as the actuating end) 154 is located in the receiving cavity 106 and is temporarily inactive; the locking pin 162 located at one end of the pawl 160 (e.g., in the shape of a shuttle) is located in the receiving recess 152, and the other end of the pawl 160 extends out of the receiving cavity 106 from the corners 1312 and 1412 as the limiting end 164; the pivot shaft 102 of the first link 1120 is located in the capturing part 163, and the pushing end 1128 of the first link 1120 is also located approximately outside the receiving cavity 106 and in front of the limiting end 164 at the corners 1312 and 1412.

[0148] In addition, Figures 12A-12E In the locked state shown, the first object 200 is located within the second object 300, that is, the first object 200 is in the initial position. The pushing end 1128 of the pull-out aid 100 is located outside the second object 300 and near the bottom of the second object 300 (specifically, the front edge of the bottom as shown). The second object 300 may include a limiting groove 310 at its bottom, and the limiting end 164 of the claw 160 is located in the limiting groove 310. Optionally, the limiting groove 310 may be formed as a strip-shaped groove extending along the insertion / removal direction (e.g., the front-to-back direction shown in the figure).

[0149] like Figures 13A-13D As shown, the fastening assembly 105 is unlocked (i.e., in the unlocked state), allowing the lever 10512 to disengage from the locking ratchet 1053 mounted on the first object 200, thus enabling the user to pull the handle 110 clockwise, thereby putting the handle 110 into the operating position. At this time, the pushing end 1128 contacts the bottom of the second object 300; the actuating member 150 remains in contact with the first connecting rod 1120 under the action of the elastic member 180 (i.e., also slightly pivoted clockwise); the locking pin 162 of the pawl 160 remains in the receiving recess 152 and the limiting end 164 remains in the limiting groove 310. In this state, the first object 200 is in the activated position and has not yet undergone relative displacement with the second object 300.

[0150] like Figures 14A-14C As shown, when the handle 110 is pulled clockwise to the first angle, the pushing end 1128 abuts against and pushes against the bottom of the second object 300, causing the second object 300 to move backward. That is, the first object 200 and the second object 300 undergo relative displacement, meaning that the first object 200 begins to be in the pulled-out position. At this time, the vacuum adsorption on the entire first object 200 is released; the actuator 400 is triggered, thereby applying an outward pushing force to the first object 200; the actuating element 150 remains tightly against the first connecting rod 1120 under the action of the elastic element 180; the locking pin 162 remains in the receiving recess 152, and the limiting end 164 begins to contact the front wall of the limiting groove 310. Optionally, the first angle at which the handle 110 pivots is in the range of 7° to 10°. For example, when the handle 110 pivots clockwise by 10°, the relative displacement between the first object 200 and the second object 300 can be 4.5 mm.

[0151] like Figures 15A-15D As shown, when the handle 110 is pulled clockwise to the second angle, the first object 200 moves forward (or outward) relative to the second object 300 under the thrust of the actuator 400. Due to the further relative displacement between the first object 200 and the second object 300, the front wall of the limiting groove 310 pushes the limiting end 164 backward (or inward), causing the pawl 160 to be driven by the second object 300 through the limiting end 164, thereby pivoting clockwise. As a result, the locking pin 162 of the pawl 160 leaves the receiving recess 152 and begins to contact and push the contact portion 1125 of the first connecting rod 1120, so that the pawl 160 also pushes the handle 110 clockwise through the locking pin 162. Moreover, during this rotation, the first connecting pin 102 gradually moves away from the capturing portion 163 of the pawl 160. Therefore, under the combined action of the user pulling, the push of the actuator 400, and the push of the locking pin 162, the clockwise rotation of the handle 110 becomes smoother, thereby facilitating the removal of the first object 200. Optionally, the second angle at which the handle 110 pivots can be in the range of greater than 10° and less than 65°.

[0152] Meanwhile, the washer 190, especially the corrugated washer, fitted on the third connecting post 104 (i.e., the pivot axis of the pawl 160) can dampen the pivoting of the pawl 160. The corrugated washer has elastic properties and can deform under pressure, absorbing and dissipating the energy generated during motion, thereby generating sliding friction on the pawl 160 and reducing the kinetic energy transmitted to the pawl 160, thus slowing down the extraction of the first object to some extent. Furthermore, as mentioned above, a washer 190 is also fitted on the pivot axis 102 of the first connecting rod 1120, thus also damping the pivoting of the first connecting rod 1120.

[0153] Therefore, the pull-out aid 100 of this application can provide braking during the pulling out of the first object 200, appropriately decelerating the first object 200 under multiple thrusts, thereby preventing the first object 200 from being ejected too quickly and avoiding damage to the first object 200 or injury to the operator. Furthermore, the damping effect helps the user control the force and speed of pulling out the first object 200, ensuring a smooth pulling process and avoiding damage to other modules inside the server. In addition, the damping effect can also prevent pressure shock waves from being generated inside the entire server due to sudden pressure release, which could damage other components. Therefore, the pull-out aid 100 of this application can improve operational safety, help operators control the pulling action more precisely, and ensure the stability and reliability of the entire system.

[0154] Figures 16A-16D The handle 110 is shown to have been rotated clockwise to a third angle. Optionally, this third angle is 65°, and the relative displacement between the first object 200 and the second object 300 can be, for example, 24.7 mm. At this point, the limiting end 164 has left the limiting groove 310 and has essentially pivoted into the receiving cavity 106, so the pawl 160 will no longer be pivoted by the second object 300 to push the pawl 162 against the contact portion 1125. In addition, after rotating to the third angle, the cylinder portion 410 and the piston portion 420 of the actuator 400 are completely separated, and their force on the first object 300 disappears; moreover, when the first object 300 continues to be pulled out, the lateral dragging force (i.e., the dragging force in the front-to-back direction) exerted by the user on the first object 200 will be greater than the clockwise pulling force generated by the puller 100.

[0155] Figures 17A-17DThe handle 110 is shown rotated clockwise to a fourth angle. Optionally, this fourth angle can be in the range of greater than 65° and less than 90°, for example, 70°. As mentioned above, after rotating to the third angle, the thrust disappears, so the user needs to manually pull the handle 110 down to the fourth angle. When rotated to this angle, the limiting end 164 separates from the limiting groove 310 (as described above), and the locking pin 162 also separates from the contact portion 1125. Therefore, the locking claw 160 cannot receive any external force and will not rotate further, thereby maintaining the angle at which it is disengaged from the bottom of the second object 300. Furthermore, during the rotation of the handle 110 from the first angle to the fourth angle, the abutting end 153 of the actuating member 150 gradually moves from the notch 1414 into the receiving cavity 106, and abuts against the contact portion 1125 when rotated to the fourth angle; simultaneously, the actuating end 154 of the actuating member 150 extends out of the receiving cavity 106 and is positioned between the pawl 160 and the first connecting rod 1120 in the front-back direction; optionally, at this time, the portion of the actuating member 150 near the actuating end 154 abuts against the mounting post 101. Additionally, during the aforementioned rotation, the protrusion 1126 of the first connecting rod 1120 gradually passes the pivot axis of the pawl 160 (i.e., the third connecting post 104), and the limiting portion 1127 of the first connecting rod 1120 contacts and receives the pivot axis of the pawl 160 (connected to the pawl 160). Figure 16C and Figure 17C At this point, the handle 110 has rotated to its maximum clockwise angle, and because the abutment end 153 is pressed against the contact portion 1125 by the elastic member 180, the handle 110 cannot rotate back (i.e., rotate counterclockwise). Therefore, the handle 110 can no longer rotate, i.e., it is in a fixed position. At this time, the user can use the handle 110 as a handle for lifting, moving, and transporting the first object 200.

[0156] It is understandable that from the time the handle 110 is unlocked until it is rotated to the fourth angle, the handle 110 is in the operating position; when the handle 110 is rotated to the fourth angle, the handle 110 reaches the fixed position.

[0157] The following reference Figures 18A-19D The process of the puller 100 is described, in which the puller 100 assists the user in inserting the first object 200 into the second object 300.

[0158] Figures 18A-18DThe handle 110 is shown still in the fourth angle; however, although the handle 110 has not yet rotated, it can rotate counterclockwise. As described above, the actuating end 154 of the actuating member 150 extends out of the receiving cavity 106, that is, it is exposed outside the first object 200. Therefore, when the user inserts the first object 200 into the second object 300, the user pushes the first object 200 forward. First, the actuating end 154 touches the bottom of the second object 300, and due to the relative movement of the first object 200 and the second object 300, the actuating end 154 is pushed forward by the second object 300, thereby overcoming the elastic force of the elastic member 180 and causing the actuating member 150 to pivot counterclockwise, thereby releasing the restriction on the handle 110. At this time, the abutting end 153 separates from the handle 110, so the handle 110 can rotate counterclockwise, that is, the handle 110 begins to be in the operating position.

[0159] Figures 19A-19D The diagram shows the handle 110 rotated counterclockwise to a fifth angle. Optionally, this fifth angle is less than the value of the fourth angle (e.g., 70°) but greater than 0°. When the handle 110 is in the operating position, the user rotates the handle 110 counterclockwise, causing the contact portion 1125 to touch and drive the locking pin 162, thereby causing the locking claw 160 to pivot counterclockwise. The limiting end 164 of the locking claw 160 then abuts against the second object 300 again, specifically, for example, touching the rear wall of the limiting groove 310. At this time, the boosting stroke begins. Then, the user continues to rotate the handle 110 counterclockwise, and the limiting end 164 falls into the groove 310 and engages with the groove 310, pushing the locking claw 160 to rotate counterclockwise.

[0160] The following describes some positions during the boosting process (i.e., the counterclockwise rotation of handle 110) as an example.

[0161] When the handle 110 is rotated counterclockwise to, for example, 56°, the distance between the first panel 210 of the first object 200 and the front edge of the bottom of the second object 300 is, for example, 27 mm. At this time, the actuator 400 has just completed its pre-travel and is about to enter the mating stroke. In this situation, the user cannot push the first object 200 into the second object 300 by hand, so the first object 200 will remain in this position.

[0162] At this point, the user continues to rotate the handle 110 counterclockwise, causing the contact portion 1125 to touch and drive the locking pin 162, thereby pivoting the locking claw 160 counterclockwise, and the limiting end 164 of the locking claw 160 abuts against the rear wall of the limiting groove 310 again. At this time, the boosting stroke begins. Optionally, during this process, the handle 110 can be rotated counterclockwise, for example, from 56° to 45°.

[0163] Next, as the handle 110 continues to rotate counterclockwise to 40°, the contact portion 1125 continues to drive the locking pin 162, causing the limiting end 164 to fall into the limiting groove 310. At this time, the distance between the first panel 210 of the first object 200 and the front edge of the bottom of the second object 300 is 23.8 mm. When the handle 110 continues to rotate counterclockwise to, for example, 30°, the distance between the first panel 210 of the first object 200 and the front edge of the bottom of the second object 300 is 17.3 mm.

[0164] Then, as the handle 110 continues to rotate counterclockwise to, for example, 20°, the distance between the first panel 210 of the first object 200 and the front edge of the bottom of the second object 300 is 11.5 mm, and the claw 160 is substantially perpendicular to the bottom of the second object 300. Optionally, when the limiting end 164 falls substantially vertically into the limiting groove 310, the limiting end 164 can be substantially flush with the bottom surface of the second object 300. In this way, on the one hand, the limiting end 164 is allowed to cooperate with the limiting groove 310 to realize the pull-out and push-out processes; on the other hand, although the distance between the entire server and the mounting base is small (for example, about 3 mm), since the limiting end 164 does not protrude substantially from the bottom surface of the second object 300, the puller is not affected by the installation space when performing the push / pull-out function.

[0165] When the handle 110 continues to rotate counterclockwise to, for example, 10°, the distance between the first panel 210 of the first object 200 and the front edge of the bottom of the second object 300 is 6.0 mm. When the handle 110 continues to rotate counterclockwise to, for example, 2-3°, the cylinder 410 and piston 420 of the actuator 400 are fully engaged, that is, the engagement stroke of the actuator 400 is completed. At this time, the handle 110 and the first panel 210 still have an angle of about 2-3°, which is designed to maintain the thrust. The user can push the handle 110 to 0° and lock the handle 110 back to the first panel 210 by means of the fastening assembly 105.

[0166] It should be understood that the first to fifth angles and the specific angle values ​​mentioned above refer to the angles formed by the handle 110 relative to the first panel 210 of the first object 200. It should also be understood that although some specific examples have been given above, this application is not limited to the specific values ​​mentioned above.
