The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
In the following, some embodiments of the present invention will be described in detail with reference to the accompanying drawings, and features in the following examples and examples may be combined with each other without conflict.
As shown in fig. 1, the wrench assembly 10 of the embodiment of the present invention is assembled to a plug-in module 100, the plug-in module 100 is applied to an electronic device, and the plug-in module 100 is a generic name of a module and its accessories that can be plugged into and pulled out from a chassis-type device (i.e., an electronic device, including a high performance server, a storage device, a personal computer, a switch, a router, etc.), and is mainly used for mounting a circuit board, a hard disk, an optical drive, etc. The plug-in module 100 comprises a module frame 110 and the wrench assembly 10, and the plug-in module 100 is locked on the chassis type equipment by the wrench assembly 10.
As shown in fig. 2 to 4, the wrench assembly 10 of the present invention includes a wrench 11, an adapter block 13, and an unlocking member 15, wherein the wrench 11 and the adapter block 13 are respectively rotatably connected to a module frame 110. The unlocking piece 15 and the switching piece 13 are arranged in a linkage manner to be matched with the wrench 11 to lock or unlock the wrench 11.
The wrench 11 includes a wrench body 111 and a locking portion 112 disposed at an end of the wrench body 111. Correspondingly, the adapter block 13 includes a hook portion 131 adapted to the snap-fit portion 112. The unlocking member 15 is used to drive the transfer block 13 to rotate, so that the hook portion 131 is disengaged from the engaging portion 112, and the locking state of the transfer block 13 to the wrench 11 is released.
It should be noted that, in the present invention, when the wrench 11 is in the locked state, the hook portion 131 of the adapting block 13 is engaged with the engaging portion 112 at the end of the wrench 11, and the top end of the wrench 11 is locked to the equipment such as a chassis, so that the plugging module 100 can be locked in the equipment such as a chassis. When the wrench 11 is unlocked, the end of the wrench 11 can be rotated out from the front panel 101 to unlock the wrench 11 from the chassis.
In the embodiment, when the wrench 11 is in the locked state, the wrench 11 and the unlocking member 15 do not exceed the front panel 101 of the module frame 110, and the arrangement is such that the wrench assembly 10 of the present invention is located within the contour of the module frame 110, and does not occupy the space of the module front panel 101, which has the effect of hiding the wrench compared with the prior art.
The wrench assembly 10 may be mounted on the upper end surface or the lower end surface of the module frame 110. The chassis-type device generally has a plurality of slots for assembling the plug-in modules 100, and when the chassis-type device is assembled with a plurality of plug-in modules 100, the wrench assembly 10 is located between two adjacent plug-in modules 100, so that the wrench assembly 10 is hidden.
Because the plug-in modules 100 in the chassis equipment are of a plurality of types and have functional coordination with each other, the chassis equipment has strict requirements on the plug-in sequence of the plug-in modules 100 so as to ensure the normal operation of the chassis equipment. The wrench assembly 10 of the present invention may also facilitate the sequential disassembly of the jack module 100 by being disposed on the upper or lower end surface of the module frame 110.
Specifically, in the embodiment where the wrench assembly 10 is disposed on the lower end surface of the module frame 110, when the plug-in module 100 is detached from the chassis-like device, since the wrench assembly 10 does not exceed the front panel 101 of the module frame 110, the plug-in module 100 below the target plug-in module 100 needs to be detached in advance, and then the target plug-in module needs to be detached, that is, when the plug-in module 100 is full, the plug-in modules 100 need to be sequentially detached from bottom to top. Similarly, in the embodiment where the wrench assembly 10 is disposed on the upper end surface of the module frame 110, the plug-in modules 100 are sequentially removed from top to bottom.
The wrench assembly 10 further includes a first pin 121 and a second reset member 12 connected to the first pin 121, and the wrench 11 is rotatably connected to the module frame 110 through the first pin 121. Wherein, the first pin shaft 121 is rotatably connected with the top end of the wrench 11. In the present invention, when the hook portion 131 is engaged with the engaging portion 112, the wrench 11 is in a locked state; when the locked state of the wrench 11 is released, the wrench 11 is rotated by the second restoring member so that the tip of the wrench 11 goes beyond the front panel 101 of the module frame 110.
In an embodiment, the second reset element 12 is a torsion spring, the torsion spring is sleeved on the first pin 121, one torsion arm of the torsion spring abuts against the wrench 11, and the other torsion arm is connected to the module frame 110. When the wrench 11 is in a compressed state, the torsion spring is in a torsional state, and the torsion spring applies a force to the wrench 11 under the action of a restoring force. When the adapter block 13 is unlocked from the wrench 11, the wrench 11 rotates the end of the wrench 11 out of the front panel 101 of the module frame 110 under the action of the torsion spring, so that the operator can perform a rotating operation. Of course, the second restoring member 12 of the present invention is not limited to a torsion spring, and any elastic structure that can drive the wrench 11 to rotate out of the front panel 101 of the module frame 110 is also suitable for the present invention.
Further, the wrench assembly 10 further includes a limiting member 17 disposed on the module frame 110, and the limiting member 17 is disposed on a rotation path of the wrench 11. The top end of the wrench 11 is provided with a stopping portion 113, and the wrench body 111 is provided with a limiting groove 114 matching with the limiting member 17. The stopping portion 113 and the limiting groove 114 are respectively matched with the limiting member 17 to limit the rotation range of the wrench 11. The limiting member 17 can be selected from a I-shaped nail, a screw or a connecting column. In this embodiment, the wrench 11 has a 3 ° over-pulling design during the rotation process, so as to compensate the fit clearance between the connector of the plug-in module 100 and the connector of the chassis-like device.
The wrench assembly 10 further includes a second pin 141 and a third reset member 14 connected to the second pin 141, the transfer block 13 is rotatably connected to the module frame 110 by the second pin 141, and the third reset member 14 acts on the transfer block 13 by a restoring force to make the hook portion 131 tend to engage with the engaging portion 112.
In one embodiment, the third restoring member 14 is a torsion spring, one torsion arm of the torsion spring is connected to the transfer block 13, and the other torsion arm is connected to the module frame 110. When the unlocking member 15 acts on the transfer block 13 to drive the hook portion 131 of the transfer block 13 to be disengaged from the engagement portion 112, the torsion spring is in a torsion state, and the torsion spring applies force to the transfer block 13 by the restoring force. After the driving force of the unlocking member 15 is removed, the switching piece 13 is returned to the position of being engaged with the wrench 11 by the torsion spring. Of course, the third restoring member 14 of the present invention is not limited to a torsion spring, and any elastic structure that can drive the transfer block 13 to return to the position of being engaged with the wrench 11 is also suitable for the present invention.
As shown in fig. 5, in the present invention, the hook portion 131 includes a first mating surface 1311 and a hook surface 1312 connected to the first mating surface 1311, and the first mating surface 1311 is a top end surface of the hook portion 131. The snap-fit portion 112 includes a second abutting surface 1121 and a snap-fit surface 1122 connected to the second abutting surface 1121, and the second abutting surface 1121 is a top end surface of the snap-fit portion 112. The first mating surface 1311 and the second mating surface 1121 are matched with each other to guide sliding.
As shown in fig. 2 to 5, in this embodiment, the first abutting surface 1311 and the second abutting surface 1121 are circular arc surfaces or guiding slope surfaces that are engaged with each other to guide the engagement. Since the adapting block 13 is located at a position where it is clamped with the wrench 11 under the action of the third resetting member 14, when the wrench 11 needs to be rotated to be locked with the chassis-like device, an operator applies force to the wrench 11 to rotate the wrench 11 until the second abutting surface 1121 of the wrench 11 abuts against the first abutting surface 1311, and the adapting block 13 is driven to rotate to avoid the wrench 11 by sliding relative to each other (at this time, the third resetting member 14 is in a torsional state), and after the latching portion 131 slides over the second abutting surface 1121, the adapting block 13 enables the latching portion 131 to be clamped with the latching portion 112 under the action of a restoring force of the third resetting member 14, so that the locking of the wrench is completed.
As shown in fig. 3, the unlocking member 15 of the present invention is used to drive the rotation of the transfer block 13. Specifically, the unlocking member 15 drives the transfer block 13 to rotate clockwise, so that the hook 131 is engaged with the engaging portion 112, and the wrench 11 is locked. The unlocking member 15 drives the transfer block 13 to rotate counterclockwise to disengage the hook 131 from the engaging portion 112, thereby unlocking the wrench 11 from the transfer block 13.
In one embodiment, as shown in fig. 2-4, the unlocking member 15 includes a handle block 151. The handle block 151 is slidably coupled to the module frame 110 in a direction perpendicular to the front panel 101 of the module frame 110, and the handle block 151 is coupled to the transfer block 13 and drives the transfer block 13 to rotate during the sliding of the handle block 151. The design of this handle piece 151 can make things convenient for operating personnel to operate, and the mode of regulation is simple and convenient, and the slip through pulling this handle piece 151 can drive the rotation of block 13 and relieve the locking state to spanner 11 promptly.
Wherein, one side of the handle block 151 opposite to the switching block 13 is provided with a chute 1511, and the switching block 13 is provided with a slide block 132 matched with the chute 1511. In the sliding process of the handle block 151, the sliding block 132 abuts against the sliding groove 1511, so as to drive the adaptor plate 13 to rotate. In the process, the sliding block 132 slides relative to the sliding groove 1511 as a whole, and the depth of the sliding block 132 in the sliding groove 1511 is different during the rotation of the transfer block 13. Specifically, when the hook 131 of the adapter block 13 is engaged with the engaging portion 112, the slider 132 is located at the deepest depth in the sliding groove 1511; when the adaptor block 13 rotates to make the hook portion 131 disengage from the snap-fit portion 112, the slider 132 is located at the shallowest depth in the sliding groove 1511.
Further, an arc-shaped guiding portion 1512 for engaging and abutting with the sliding block 132 is protruded from a sidewall of the sliding groove 1511 away from the front panel 101. In this embodiment, the arc guiding portion 1512 is an arc protrusion having a smooth arc surface. Specifically, in the process that the handle block 151 is pulled out in the direction perpendicular to the front panel 101, the slider 132 abuts against the arc guide portion 1512 and slides relatively along the arc surface of the arc guide portion 1512, and the slider 132 abuts against and slides to the other end from one end of the arc surface protruding from the arc, so that the unlocking piece 15 drives the switching block 132 to rotate more smoothly.
The unlocking member 15 of the present invention further includes a first reset member 152 connected to the handle block 151 and the module frame 110, respectively. When the handle block 151 is in the first position (as shown in fig. 3), the wrench 11 is placed in the locked state by the engagement of the hook 131 and the engaging portion 112. When the handle block 151 is in the second position (as shown in fig. 4), the locking state of the wrench 11 is released by the hook 131 coming out of the snap fitting portion 112. Wherein, the handle block 151 is driven to slide from the second position to the first position by the first restoring member 152.
In an embodiment, the first reset member 152 is a tension spring, and when the handle block 151 slides out in a direction perpendicular to the front panel 101 under the action of an external force, the handle block 151 drives the adaptor block 13 to rotate so that the adaptor block 13 releases the locking state of the wrench 11. At this time, the first restoring member 152 is in an elastic stretching state, and the first restoring member 152 generates a pulling force on the handle block 151 under the restoring force. After the external force on the handle block 151 is removed, the handle block 151 slides back under the restoring force of the first restoring member 152, and at this time, the transfer block 13 can be driven to rotate so that the transfer block 13 returns to the position of being clamped with the wrench 11. In this embodiment, under the combined action of the restoring force of the first restoring member 152 and the restoring force of the third restoring member 14, the adaptor block 13 is more easily restored to the position of engaging with the wrench 11. The first restoring member 152 of the present invention is not limited to a tension spring, and in other embodiments, the first restoring member 152 may also be an elastic structure such as an elastic plastic member or an elastic rope.
The handle block 151 is provided with a waist-shaped hole 1513, the unlocking member 15 further includes a limiting member 1514 disposed in the module frame 110, and the waist-shaped hole 1513 is inserted through the limiting member 1514. The handle block 151 is engaged with the stopper 1514 through the waist-shaped hole 1513 so that the handle block 151 can slide in a direction perpendicular to the front panel 101. In this embodiment, the length direction of the slotted hole 1513 is the same as the sliding direction of the handle block 151, and the length dimension of the slotted hole 1513 defines the sliding range of the handle block 151. The position-limiting element 1514 may be a stud or other protruding post-like structure.
In this embodiment, the handle block 151 is provided with a waist-shaped hole 1513 and a limiting element 1514 on both sides thereof, so as to ensure that the handle block 151 slides smoothly. In another embodiment, the handle block 151 can also slide in a manner of a slide rail and a slide block. Specifically, a slide rail (not shown) is disposed on one side of the handle block 151 opposite to the module frame 110, and a slider (not shown) adapted to the slide rail is disposed on the module frame 110; or a sliding block is arranged on one side of the handle block 151 opposite to the module frame body 110, and a sliding rail matched with the sliding block is arranged on the module frame body 110.
The grip block 151 is provided with a grip 1515, and the operator can pull out the grip block 151 located on the upper end surface or the lower end surface of the module case 110 from the front panel 101 by applying the grip 1515 to the grip block 151. In this embodiment, the holding portion 1515 is a through hole, and the operator can pull out the handle block 151 by extending into the through hole. Of course, in other embodiments, the holding portion 1515 may be a handle or a protrusion disposed on the handle block 151.
In another embodiment, a side surface of the handle block 151 opposite to the adapter block 13 is provided with a rack, and a peripheral side surface of the adapter block 13 is provided with teeth matched with the rack. When the handle block 151 slides in a direction perpendicular to the front panel 101, the gear rack is engaged with the gear on the adapter block 13 to drive the adapter block 13 to rotate.
In another embodiment, the unlocking member 15 includes a gear plate having teeth on its outer peripheral surface, the gear plate is rotatably connected to the module frame 110, the gear plate is engaged with the teeth on the outer peripheral surface of the adapter block 13, and the adapter block 13 is driven to rotate by the engagement of the gear plate and the teeth on the adapter block 13, i.e., the adapter block 13 rotates synchronously with the rotation of the gear plate. The toothed plate portion projects above the front panel 101 of the module frame 110 to allow an operator to apply force to rotate the toothed plate.
In another embodiment, the unlocking member 15 comprises a pulling cable wound around the junction block 13, specifically around the outer wall of the shaft of the junction block 13 connected to the second pin 141, and the junction block 13 rotates under the pulling of the pulling cable.
As shown in fig. 1 to 5, when the plug-in module 100 of the present invention is assembled in a chassis-like device, the wrench 11 is rotated to abut against the adaptor block 13 and rotate to get out of the way, so that the wrench 11 reaches a position locked with the adaptor block 13. When the wrench 11 reaches the position of the locked state with the adapting block 13, the adapting block 13 rotates under the action of the third resetting member 14 to be locked with the wrench 11, and at this time, the wrench 11 is locked to the equipment such as a chassis (at this time, the second resetting member 12 is in a torsional and compressive state). During the rotation of the switching block 13, the unlocking member 15 is linked with the switching block 13. When the plug-in module 100 is detached from the chassis device, an operator adjusts the unlocking piece 15 to drive the adaptor block 13 to rotate (at this time, the third reset piece 14 is in a twisting state), the hook portion 131 of the adaptor block 13 is disengaged from the engagement portion 112 of the wrench 11 to unlock the wrench 11 from the adaptor block 13, and the wrench 11 is ejected from the front panel 101 of the module frame 110 by the end of the wrench 11 under the action of the restoring force of the second reset piece 12, so that the operator rotates the wrench 11 to unlock the wrench 11 from the chassis device, thereby enabling the plug-in module 100 to be pulled out from the chassis device.
