[0001] This utility model belongs to the technical field of computer room cooling equipment, and specifically relates to a self-locking phase change temperature control plate fixing device. Background Technology

[0002] A phase change temperature control plate is a device that uses the phase change process of a phase change material to achieve temperature control. Existing phase change temperature control plates are mainly fixed using traditional manual methods, typically relying on manual fixation of the plate to the mounting frame. This involves manually tightening or locking bolts, clips, and clamps. While this meets basic fixing requirements, it has the following drawbacks: 1. Manual installation is inefficient, labor-intensive, and has low work efficiency; 2. Disassembly and assembly are inconvenient, maintenance is difficult, and the disassembly process can easily damage the plate; 3. The fixation is not secure, easily leading to loosening and detachment; 4. It cannot adapt to phase change temperature control plates of different specifications and sizes, and is generally only suitable for plates with specific dimensions.

The inner wall of the rotating sleeve is provided with a protrusion that fits into the groove. The outer wall of the guide shaft is provided with a channel. The guide sleeve is provided with a protrusion. The protrusion is inserted into the channel. The protrusion is used to convert the axial reciprocating motion of the guide sleeve into the circumferential rotational motion of the guide shaft.

[0007] To better realize this utility model, further optimizations are made to the above structure. The channel includes an upper curved channel, a first straight channel, a lower curved channel, and a second straight channel that are connected end to end.

[0025] Example 1:

[0026] In this embodiment, a self-locking phase change temperature control plate fixing device, such as... Figures 1 to 5As shown, the device includes a base plate 1, a guide base 2, a drive base 3, a positioning corner sleeve 4, a transmission arm 5, and a drive device. Specifically, the base plate 1 has four radially arranged guide grooves 6 along its circumference. The four guide grooves 6 are located at the four corners of the base plate 1 and point towards the center of the base plate 1. Each guide groove 6 is slidably connected to a guide base 2. The guide base 2 can move along the guide groove 6 to approach or move away from the center of the base plate 1. The base plate 1 has a central hole, and a rotating sleeve 7 passes through the central hole. The rotating sleeve 7 can rotate relative to the base plate 1. The center of the drive base 3 is aligned with one of the rotating sleeves 7. The rotating sleeve 7 is fixedly connected to the drive base 3 and can drive the drive base 3 to rotate synchronously. The four transmission arms 5 are respectively located at the four corners of the drive base 3. One end of the transmission arm 5 is hinged to the drive base 3 and the other end is hinged to the guide base 2. The positioning corner sleeve 4 is fixed on the side of the guide base 2 away from the transmission arm 5. The driving device is set inside the rotating sleeve 7. The driving device drives the rotating sleeve 7 and the drive base 3 to rotate. The drive base 3 drives the guide base 2 to translate along the guide groove 6 through the transmission arms 5, so that the four guide bases 2 are closer to or farther away from the center of the base plate 1.

[0027] With this structure, the phase change temperature control plate is installed through the four positioning corner sleeves 4. The driving device drives the guide base 2 to move along the guide groove 6, so that the positioning corner sleeves 4 clamp the phase change temperature control plate, making the fixation more secure. The driving device can drive in reverse to make the positioning corner sleeves 4 loosen the phase change temperature control plate, making disassembly and assembly more convenient. It can also be adapted to phase change temperature control plates of different specifications and sizes, making the utility model more practical.

[0028] As one specific implementation method of this embodiment, such as Figure 4 and Figure 5As shown, the aforementioned driving device includes a guide shaft 8, a guide sleeve 9, a button shaft 10, and a spring 11. The spring 11 is connected between the guide shaft 8 and the button shaft 10. The guide sleeve 9 is fitted over the guide shaft 8, spring 11, and button shaft 10. The button shaft 10 and the guide sleeve 9 are connected by threads. The outer wall of the end of the guide shaft 8 away from the button shaft 10 has a groove 12. The inner wall of the rotating sleeve 7 has a protrusion 13 that fits into the groove 12. The outer wall of the guide shaft 8 has a channel. The guide sleeve 9 has a protrusion 14 that is inserted into the channel. The protrusion 14 is used to convert the axial reciprocating motion of the guide sleeve 9 into the circumferential rotational motion of the guide shaft 8. Specifically, the channel includes a first... The upper curved channel 15, the first straight channel 16, the lower curved channel 17, and the second straight channel 18 are connected at the tail. The upper curved channel 15 and the lower curved channel 17 are arc-shaped inclined channels extending outward from the guide shaft 8, with opposite inclination directions. At the four corners of the channels are respectively provided a first step 19, a second step 20, a fourth step 21, and a fifth step 22. The middle of the first straight channel 16 is provided with a third step 23, and the middle of the second straight channel 18 is provided with a sixth step 24. In use, pressing the button shaft 10 causes the guide sleeve 9 to move towards one end of the drive base 3, allowing the protruding post 14 to move along the first straight channel 16 and pass through the third step 23 and the fourth step 21. Then, entering the lower curved channel 17, the protruding post 14 continues to move along the path of the lower curved channel 17, thereby forcing the guide shaft 8 to rotate until the protruding post 14 passes through the fifth step 22 and enters the second straight channel 18. The guide shaft 8 drives the rotating sleeve 7 to rotate through the groove 12 and the protruding strip 13. The rotating sleeve 7 drives the driving base 3 to rotate, so that the driving base 3 drives the four guide bases 2 to translate along the guide groove 6 towards the center of the bottom plate 1 through the transmission arm 5, thereby clamping the phase change temperature control plate. At the same time, the protruding post 14 enters the second straight channel 18 and is no longer constrained by the lower curved channel 17 in the axial direction. The spring 11 restores its deformation to push The button shaft 10 and guide sleeve 9 are simultaneously lifted and translated, causing the protruding post 14 to move in the opposite direction along the second straight channel 18 and pass through the sixth step 24 and the first step 19, entering the upper curved channel 15. All the steps act as a stop during the process. When it is necessary to release, the button shaft 10 is pressed again. The button shaft 10 drives the guide sleeve 9 to move towards one end of the drive base 3, causing the protruding post 14 to move along the path of the upper curved channel 15. The inclination direction of the upper curved channel 15 is exactly opposite to the direction of the lower curved channel 17, thereby forcing the guide shaft 8 to rotate in the opposite direction. This causes the guide shaft 8 to drive the rotating sleeve 7 to rotate in the opposite direction, and the rotating sleeve 7 in turn drives the drive base 3 to rotate in the opposite direction.The drive base 3, via the transmission arm 5, drives the four guide bases 2 to move along the guide groove 6 away from the center of the base plate 1. The guide bases 2 gradually open outwards, causing the positioning sleeves 4 to open as well. This gradually reduces the clamping force of the positioning sleeves 4 on the phase change temperature control plate, causing them to loosen. Finally, the positioning sleeves 4 fully open and return to their initial position, allowing the phase change temperature control plate to be completely released, completing the disassembly operation. At this point, the protruding post 14 returns to the first straight groove 16 via the second step 20, ready for the next clamping operation. The stepped structure provides a stable locking function throughout the process, preventing possible slippage or loosening during operation, further improving the safety and reliability of the device.

[0029] In this embodiment, the curvature of the upper curved channel 15 and the lower curved channel 17 is 90°, so that the forward and reverse rotation angles of the guide shaft 8 are constant at 90°.

[0030] In this embodiment, as Figure 4 As shown, the outer wall of the rotating sleeve 7 is provided with an annular groove 25. The annular groove 25 is in clearance fit with the center hole of the base plate 1, so that the rotating sleeve 7 will not detach from the base plate 1, and can drive the driving base 3 to rotate synchronously under the drive of the guide shaft 8 and the guide sleeve 9, so that the driving base 3 and the base plate 1 are misaligned in the circumferential direction, and finally the opening and clamping action of the guide base 2 is formed.

[0031] In this embodiment, as Figure 2 As shown, the positioning corner sleeve 4 is a right-angled triangular sleeve, and the four positioning corner sleeves 4 are arranged in a rectangle. The hypotenuses of the two diagonally opposite positioning corner sleeves 4 are arranged opposite each other. The hypotenuses of the positioning corner sleeves 4 are provided with openings 26. The four corners of the phase change temperature control plate are respectively inserted into the openings 26 of the positioning corner sleeves 4. The four positioning corner sleeves 4 are opened and clamped by the guide base 2, thereby realizing the fixing and loosening of the phase change temperature control plate, and it can be applied to phase change temperature control plates of different sizes.

[0032] In this embodiment, as Figure 2 As shown, one right-angled side of the aforementioned positioning corner sleeve 4 is provided with a connecting piece 27. Two adjacent connecting pieces 27 are aligned. Each connecting piece 27 has a strip groove 28, and the strip grooves 28 of the two connecting pieces 27 overlap. A slider passes through the strip groove 28. The connecting piece 27 is used to connect the two positioning corner sleeves 4 of the crossbeam, ensuring the overall structural strength and stability.

[0033] The aforementioned self-locking phase change temperature control plate fixing device, through the self-locking guide shaft 8 and guide sleeve 9, combined with the aforementioned channel and stepped structure, and in conjunction with the aforementioned drive base 3, guide base 2 and positioning corner sleeve 4, realizes the rapid clamping and loosening of the phase change temperature control plate, significantly improving operational efficiency and usage stability. At the same time, the reverse rotation path provided by the aforementioned guide groove 6 ensures that the disassembly process is simple and quick, avoiding the tool use and time waste caused by traditional methods. In addition, the modular design of this invention makes it more applicable, compatible with various specifications of phase change temperature control plates, adaptable to different working conditions, and exhibiting better reliability and durability. This gives the device significant technical advantages in improving the convenience of installation and disassembly, enhancing stability and applicability.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
