Description

Technical Field

[0001] This utility model relates to a housing device; in particular, it refers to a housing with a replaceable module. Background Technology

[0002] Existing rack-mounted equipment, such as coolant distributors, has a motor inside its casing that functions as a device to deliver coolant. When the motor in the coolant distributor fails and needs to be replaced, it is generally necessary to remove the coolant distributor from the rack, disassemble the coolant distributor's casing, and then replace the motor. This design makes the motor replacement process lengthy and inconvenient.

[0003] Therefore, it is necessary to provide an improved enclosure structure that allows operators to quickly replace functional devices within the equipment without removing the equipment installed in the cabinet. This reduces the time required to replace functional devices when they fail, and allows the cabinet system to be restored to operation more quickly. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a housing in which a replaceable module is provided, so that when the functional device is set in the replaceable module, the required functional device can be quickly replaced in the housing by the function of the replaceable module being replaceable in the housing.

[0005] To achieve the above objectives, this utility model provides a housing with a replaceable module, comprising a housing body and a replaceable module. The housing body has an internal installation space and an external replaceable panel, the replaceable panel having a replaceable opening, and a positioning pin hole formed on the peripheral wall of the replaceable opening.

[0006] The replaceable module includes a support base, a turntable base, a turntable, a locking pin assembly, and a positioning pin assembly. The support base, the turntable base, the locking pin assembly, and the positioning pin assembly are located in the installation space, and the support base is connected to the turntable base. The turntable base is correspondingly disposed at the replaceable port and has a positioning hole and a locking hole in its surrounding portion, with the positioning hole facing the positioning pin hole. The turntable is rotatably coupled to the turntable base, and a track and a rotating rod are formed at an eccentric position on the side of the turntable facing the support base. The track extends radially along the turntable, and one end of the track leads to the locking hole. The eccentric position of the turntable has a locking button opening, which communicates with the track.

[0007] The locking pin assembly is disposed within the track and has a button element. The button element protrudes from the locking button opening and is used to drive a locking pin. One end of the locking pin corresponding to the locking hole is movably inserted into the locking hole. The positioning pin assembly includes a pin seat and a positioning pin. The pin seat is coupled to the turntable seat and has a through hole. The through hole communicates with the positioning hole. The positioning pin passes through the through hole and the positioning hole. One end of the positioning pin corresponding to the positioning pin hole is movably inserted into or disengaged from the positioning pin hole. The other end of the positioning pin is connected to a linkage element. The linkage element is driven by the rotating rod to cause the positioning pin to slide along the through hole into or disengage from the positioning pin hole.

[0008] In use, this invention incorporates a functional device within the support of the replaceable module. When the functional device malfunctions and needs replacement, the user operates the button element to move one end of the locking pin corresponding to the locking hole out of the locking hole, releasing the turntable. The user can then rotate the turntable to rotate the rotating rod. During the rotation of the rotating rod, the rod drives the linkage element, which, driven by the rotating rod, allows the end of the positioning pin corresponding to the positioning pin hole to be movably inserted into or disengaged from the positioning pin hole. When the end of the positioning pin corresponding to the positioning pin hole is inserted into the positioning pin hole, the replaceable module is fixed to the replacement port of the housing body; when the end of the positioning pin corresponding to the positioning pin hole is disengaged from the positioning pin hole, the replaceable module is in a released state.

[0009] The advantage of this invention is that, when the replaceable module is in the released state, it can be pulled out and replaced through the replacement port of the housing body. By removing and replacing the module through the replacement port, the required functional devices can be quickly replaced within the housing body, achieving the effect of quickly replacing functional devices without disassembling the housing body.

[0032] The turntable 30 is rotatably coupled to the turntable base 20 and includes a disc body 32 and a handle 34. The disc body 32 is a circular plate with an annular step 321 formed on the side of its periphery facing away from the support base 10. The annular step 321 slidably abuts against the periphery of the turntable hole 222. A tube 322 is connected to the center of the disc body 32 facing the support base 10. The tube 322 is a circular tube extending in the front-back direction and rotatably fitted onto the shaft 242, thus allowing the disc body 32 to be rotatably disposed in the turntable hole 222.

[0033] A locking button opening 323 is formed in the middle of the left side of the disc body 32. The locking button opening 323 is a rectangular through hole located at an off-center position on the disc body 32. Specifically, at the off-center position on the side of the disc body 32 facing the support base 10, a pair of sidewalls 324 are connected to the middle of the left front of the disc body 32. The opposite sidewalls 324 are located on the upper and lower sides of the locking button opening 323, and a pair of grooves 3241 are formed in the middle of the opposite sidewalls 324, which extend in the front-back direction.

[0034] A cover 325 covers the opposite sidewall 324 and is attached to the disc body 32. A track 326 is formed between the opposite sidewall 324 and the cover 325. The track 326 extends radially along the disc body 32, with its left end leading to the locking hole 243 and its left end communicating with the locking button opening 323. A guide tube 327 is connected to one side of the outer circumference of the tube portion 322. The guide tube 327 is a tube with its left end facing the right end of the track 326. A rotating rod 328 is attached at an eccentric position on the side of the disc body 32 facing the support seat 10, specifically at the middle of the right front side of the disc body 32. The rotating rod 328 is a round rod extending in the front-rear direction.

[0035] The grip 34 is screwed onto the other side of the disc body 32 opposite to the turntable base 20. Specifically, the grip 34 is a U-shaped handle and is screwed onto the opposite sides of the disc body 32 at both ends. The grip 34 has a button through hole 341, which is a through hole extending in the front-back direction. The front end of the button through hole 341 communicates with the locking button opening 323.

[0036] Please refer to Figures 5 to 9 As shown, the locking pin assembly 40 is disposed within the track 326 and includes a button element 42, a locking pin 44, and a button spring 46. The button element 42 includes a slider 421 and a button block 422. The slider 421 is a block disposed on the track 326 and can slide radially along the disc body 32 on the track 326. A pin through hole 4211 is formed in the slider 421, and the direction of the pin through hole 4211 is parallel to the direction of the track 326. A screw through hole 4212 is formed in the slider 421, and the direction of the screw through hole 4212 is perpendicular to the direction of the track 326. The screw through hole 4212 communicates with the pin through hole 4211. A driven inclined surface 4213 is formed on the side of the slider 421 facing the locking hole 243. The driven inclined surface 4213 is an inclined surface.

[0037] The button block 422 is a block that passes through the button through hole 341 and the locking button opening 323, and the button block 422 can slide in the front-back direction, thus exposing the button element 42 in the locking button opening 323. A pair of protrusions 4221 are connected to the upper and lower sides of the front end of the button block 422. The protrusions 4221 are inserted into the split groove 3241 and can slide back and forth along the split groove 3241 in the front-back direction, thereby restricting the button block 422 to slide only in the front-back direction and preventing it from falling out of the button through hole 341. A driving slope 4222 is formed at the front end of the button block 422 facing the support base 10. The driving slope 4222 is an inclined surface and slidably abuts against the driven slope 4213 of the slider 421. The driving slope 4222 forms a pin groove 4223 corresponding to the locking pin 44.

[0038] The locking pin 44 is a long rod extending radially along the disc body 32. The locking pin 44 has a fixing screw hole 441 in the middle, and the portion of the locking pin 44 with the fixing screw hole 441 passes through the pin through hole 4211 of the slider 421. A screw 45 is provided in the screw through hole 4212, and the screw 45 passes through the screw through hole 4212 and is screwed into the fixing screw hole 441, thus fixing the slider 421 to the locking pin 44. One end of the locking pin 44 corresponding to the locking hole 243 is inserted into the locking hole 243, and the other end of the locking pin 44 passes through the guide tube 327. The button spring 46 is fitted onto the locking pin 44. The button spring 46 is in a compressed state, with one end abutting against the guide tube 327 and the other end abutting against the slider 421, so that the button spring 46 can push the slider 421 and the locking pin 44 towards the locking hole 243.

[0039] Please refer to Figure 9 and Figure 10As shown, when the user holds the handle 34 and presses the button block 422 forward, the driving slope 4222 of the button block 422 pushes the driven slope 4213, causing the slider 421 and the locking pin 44 to move inward along the track 326. As the button block 422 moves further forward, the pin groove 4223 of the button block 422 can accommodate the portion of the locking pin 44 adjacent to the driven slope 4213, preventing interference between the driving slope 4222 and the locking pin 44. When the user drives the slider 421 and the locking pin 44 to move inward along the track 326 by pressing the button block 422 forward, the turntable 30 is released as soon as one end of the locking pin 44 corresponding to the locking hole 243 disengages from the locking hole 243. The user can then rotate the turntable 30 by turning the handle 34. During this process, one end of the locking pin 44 corresponding to the locking hole 243 moves with the rotation of the turntable 30 and can be movably inserted into the unlocking hole 244, allowing the turntable 30 to reposition itself after rotating 90 degrees. In other embodiments, the unlocking hole 244 may not be provided, in which case the turntable 30 does not have the function of repositioning after being released and rotated.

[0040] Please refer to Figure 3 , Figures 6 to 7 and Figures 10 to 12 As shown, the positioning pin assembly 50 includes a pin seat 52, a positioning pin 54, and a linkage element 56. The pin seat 52 is attached to the lower side of the peripheral portion of the outer cover 22, and the pin seat 52 is located within the recess 245; the pin seat 52 has a through hole 521, which is a straight hole extending in the vertical direction and communicating with the positioning hole 221. Specifically, the through hole 521 has a large diameter portion 5211 and a small diameter portion 5212, and a shoulder portion 5213 is formed between the large diameter portion 5211 and the small diameter portion 5212. The large diameter portion 5211 is adjacent to the positioning hole 221. The positioning pin 54 is a long straight rod that passes through the through hole 521. One end of the positioning pin 54 has a head 541. A pin spring 55 is fitted onto the positioning pin 54. The pin spring 55 is in a compressed state and its two ends abut against the shoulder 5213 and the head 541 respectively. The positioning pin 54 inserts its head 541 into the positioning pin hole A5 of the replaceable port A4, so that the replaceable module 100 is in a locked state.

[0041] The linkage element 56 has a linkage element body 561, which is a block and rotatably pivotally connected to the other end of the positioning pin 54. A contact surface 562 is formed on the side of the linkage element body 561 facing the pin seat 52, and the contact surface 562 abuts against the pin seat 52. Support points 563 are formed on both sides of the contact surface 562 perpendicular to the axial direction of the positioning pin 54, and each support point 563 has a rounded corner shape. A swing arm 564 is connected to the linkage element body 561. The swing arm 564 is a vertical plate extending from the linkage element body 561 into the turntable seat 20, and the swing arm 564 is located on the path of the rotating rod 328 as the turntable 30 rotates. In other preferred embodiments, the support point 563 may be formed only on one side of the contact surface 562 perpendicular to the axial direction of the positioning pin 54.

[0042] Please refer to Figure 3 , Figure 12 and Figure 13 As shown, when the linkage element 56 is driven by the rotating rod 328, specifically, during the process of the swing arm 564 being actuated by the rotating rod 328 rotating with the turntable 30, the linkage element 56 rotates against the pin seat 52 with one of its fulcrums 563. The fulcrum 563 forms a lever support during the rotation of the linkage element 56, pulling the positioning pin 54 inward along the through hole 521, allowing the positioning pin 54 to displace inward. The head 541 of the positioning pin 54 retracts inward and leaves the positioning pin hole A5, thereby releasing the replaceable module 100, putting the replaceable module 100 in a released state. In general, by the linkage element 56 being driven by the rotating rod 328, the positioning pin 54 can slide along the through hole 521, and the end of the positioning pin 54 corresponding to the positioning pin hole A5 can be movably inserted into or disengaged from the positioning pin hole A5.

[0043] When the head 541 of the positioning pin 54 disengages from the positioning pin hole A5, the user can grasp the handle 34 and pull it backward to remove the replaceable module 100 from the housing body A1 through the replacement port A4. By replacing different replaceable modules 100, the functional device B within the housing body A1 can be quickly replaced without disassembling the housing body A1 or the carrier 10 of the replaceable module 100, saving considerable time when replacing a faulty functional device B.

[0044] Besides the first preferred embodiment described above, the linkage element 56 can also have other structures. For example... Figures 14 to 17The second preferred embodiment is shown. In the second preferred embodiment, please refer to... Figures 14 to 17 As shown, the linkage element 56A is an elongated ring with a rotating rod track 561A formed on its inner side. The extension direction of the rotating rod track 561A is perpendicular to the axial direction of the positioning pin 54A. The rotating rod track 561A has two ends, and one end is closer to the other end of the positioning pin 54A than the other end.

[0045] In this preferred embodiment, the left end of the rotating rod track 561A is closer to the other end of the positioning pin 54A than the right end; the rotating rod 328A passes through one end of the rotating rod track 561A, for example, the rotating rod 328A passes through the right end of the rotating rod track 561A. Thus, when the rotating rod 328A moves relative to the extreme positions at both ends of the rotating rod track 561A as the turntable 30A rotates, the linkage element 56A causes the positioning pin 54A to extend outward to varying degrees along the through hole 521A of the pin seat 52A. As shown in the figure, when the rotating rod 328A is located at the right end of the rotating rod track 561A, the outer end of the positioning pin 54A does not extend out of the through hole 521A, and the replaceable module (not shown in the figure) is in a released state. When the rotating rod 328A moves to the left end of the rotating rod track 561A, the rotating rod 328A drives the outer end of the positioning pin 54A to move out of the through hole 521A through the linkage element 56A, and the replaceable module is in a locked state.

[0046] The second preferred embodiment is identical to the first preferred embodiment except that the structure in which the rotating rod 328A drives the linkage element 56A to move the positioning pin 54A is different from that in the first preferred embodiment.

[0047] The above description is only a preferred and feasible embodiment of this utility model. Any equivalent changes made by applying the specification and claims of this utility model should be included within the patent scope of this utility model.
