Description

Technical Field

[0001] This utility model relates to the field of sheet metal heat dissipation technology, specifically a heat dissipation structure for sheet metal parts of mechanical equipment. Background Technology

[0002] In the field of mechanical equipment, sheet metal parts are key structural and functional components, and their heat dissipation performance directly affects the stability and service life of the equipment. Traditional sheet metal heat dissipation structures mostly adopt simple punching or external heat sink designs, which have problems such as low heat dissipation efficiency, inconvenient maintenance, and poor adaptability. As the power density of equipment continues to increase, the heat dissipation requirements are becoming increasingly stringent, and conventional solutions can no longer meet the requirements of efficient, intelligent, and lightweight heat dissipation.

[0003] In the heat dissipation structure of sheet metal parts in traditional mechanical equipment, heat dissipation fins are usually fixed to the base by welding or bolts, which requires tools to disassemble during maintenance, resulting in low efficiency and easy damage to the sheet metal surface. Furthermore, heat dissipation modules made of a single material are difficult to adapt to the thermal management needs under different working conditions and lack flexibility. Utility Model Content

[0011] Preferably, the locking mechanism includes two sets of ratchet wheels symmetrically sleeved on the first or second bidirectional lead screw, and two sets of pawls corresponding to the two sets of ratchet wheels. The pawls are engaged with the corresponding ratchet wheels, and both sets of pawls are rotatably connected to the base plate via rotating rods.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a heat dissipation structure for sheet metal parts of mechanical equipment, which has the following beneficial effects:

[0017] The first and second bidirectional lead screws control the linkage and sliding of two sets of adjusting rods, respectively, to achieve synchronous displacement adjustment of four sets of positioning blocks. This design allows the mounting frame and heat sink to be quickly engaged or disengaged through the cooperation of the positioning slots and positioning blocks, enabling disassembly and assembly operations without the need for tools, significantly improving maintenance efficiency, and avoiding the risk of damage to the sheet metal surface caused by traditional welding or bolt fixing methods. The locking mechanism adopts a ratchet and pawl linkage system to achieve bidirectional self-locking function. When adjustment is required, a single pull of the connecting frame can simultaneously release the locking state of the corresponding first or second bidirectional lead screw. The pawl disengages from the ratchet through rack and pinion transmission, while the elastic engagement between the insert block and the insert frame maintains the unlocked state. After the connecting frame is released, the first torsion spring automatically resets the pawl to relock. This design ensures structural stability in the non-operational state and enables a quick unlock-adjustment-locking operation process that can be completed with one hand. Attached Figure Description

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Figures 1-4In one embodiment of this utility model, a heat dissipation structure for sheet metal parts of mechanical equipment includes a base plate 1 and a heat dissipation plate 2. A mounting frame 3 is fixedly installed on the heat dissipation plate 2 and is snapped into the base plate 1. The base plate 1 is provided with a positioning mechanism 4 for quick assembly and disassembly of the heat dissipation plate 2. The positioning mechanism 4 includes positioning grooves 401 at the four corners of the mounting frame 3 and four sets of symmetrically distributed positioning blocks 402 within the base plate 1. The four sets of positioning blocks 402 are respectively corresponding to the four sets of positioning grooves 401, and the four sets of positioning blocks 402 are movably engaged with the mounting frame 3 through the positioning grooves 401. Two sets of symmetrically distributed first adjusting rods 403 and second adjusting rods 405 are slidably installed inside the substrate 1. A set of first bidirectional lead screws 404 corresponding to the first adjusting rods 403 is rotatably installed inside the substrate 1. A set of second bidirectional lead screws 406 corresponding to the second adjusting rods 405 is rotatably installed inside the substrate 1. A locking mechanism 5 for locking the first bidirectional lead screws 404 and the second bidirectional lead screws 406 is provided inside the substrate 1. The linkage sliding of the two sets of adjusting rods is controlled by the first bidirectional lead screws 404 and the second bidirectional lead screws 406 respectively, so as to realize the synchronous displacement adjustment of the four sets of positioning blocks 402. This design allows the mounting frame 3 and the heat sink 2 to be quickly engaged or disengaged via the positioning groove 401 and positioning block 402, enabling tool-free assembly and disassembly, significantly improving maintenance efficiency and avoiding the risk of damage to the sheet metal surface caused by traditional welding or bolt fixing methods. The locking mechanism 5 uses a ratchet 501 and pawl 503 linkage system to achieve a two-way self-locking function. When adjustment is required, a single pull on the connecting frame 507 can simultaneously release the locking state of the corresponding first two-way lead screw 404 or second two-way lead screw 406. Through the transmission of rack 506-gear 505, the pawl 503 disengages from the ratchet 501, while the elastic engagement between the insert block 510 and the insert bracket 512 maintains the unlocked state. After releasing the connecting frame 507, the first torsion spring 504 automatically resets the pawl 503 to relock. This design ensures structural stability in the non-operational state and enables a quick unlock-adjustment-locking operation process that can be completed with one hand.

[0026] In this embodiment, reference Figure 2As shown, two sets of first adjusting rods 403 and two sets of second adjusting rods 405 are vertically distributed. Four sets of positioning blocks 402 are slidably connected to one set of first adjusting rods 403 and one set of second adjusting rods 405, respectively. The two ends of the first bidirectional lead screw 404 pass through the two sets of first adjusting rods 403 and are threadedly connected to the two sets of first adjusting rods 403, respectively. The two ends of the second bidirectional lead screw 406 pass through the two sets of second adjusting rods 405 and are threadedly connected to the two sets of second adjusting rods 405, respectively. Precise control is achieved through the bidirectional lead screw system. When the first bidirectional lead screw 404 is rotated, it drives the two sets of first adjusting rods 403 to move synchronously in opposite directions, thereby driving the corresponding positioning blocks 402 to slide in a straight line. Similarly, the second bidirectional lead screw 406 controls the displacement of the other two sets of positioning blocks 402. The four sets of positioning blocks 402 cooperate to insert into or withdraw from the positioning slots 401 of the mounting frame 3 to complete the clamping and fixing or quick release of the heat sink 2. The whole process does not require auxiliary tools.

[0027] In this embodiment, reference Figure 3 and Figure 4As shown, the locking mechanism 5 includes two sets of ratchet wheels 501 symmetrically sleeved on the first bidirectional lead screw 404 or the second bidirectional lead screw 406, and two sets of pawls 503 corresponding to the two sets of ratchet wheels 501. The pawls 503 are engaged with the corresponding ratchet wheels 501, and both sets of pawls 503 are rotatably connected to the base plate 1 through rotating rods 502. Gears 505 are fixedly mounted on both sets of rotating rods 502. Two sets of gears corresponding to the two sets of rotating rods 502 are slidably installed inside the base plate 1. Two sets of racks 506 are respectively connected to corresponding gears 505. A connecting frame 507 is slidably installed in the base plate 1, and the connecting frame 507 is fixedly connected to the two sets of racks 506. A slide rod 508 is fixedly installed in the base plate 1, and an insert block 510 is fixedly installed on the connecting frame 507. A first torsion spring 504 is sleeved on each of the two sets of rotating rods 502. The two ends of the first torsion spring 504 are fixedly connected to the pawl 503 and the base plate 1, respectively. The connecting frame 507 is respectively connected to the two sets of racks 506. The slide rod 508 is slidably sleeved, and two sets of symmetrically distributed springs 509 are sleeved on the slide rod 508. The two ends of the two sets of springs 509 are respectively fixedly connected to the connecting frame 507 and the base plate 1. The base plate 1 is fixedly installed with a plug rod 511 corresponding to the plug block 510. Two sets of symmetrically distributed plug brackets 512 are sleeved on the plug rod 511, and the two sets of plug brackets 512 are respectively movably engaged with the plug block 510. Two sets of symmetrically distributed second torsion springs 513 are sleeved on the plug rod 511, and the second torsion springs... Both ends of the spring 513 are fixedly connected to a set of corresponding insert brackets 512 and insert rods 511, respectively. The locking mechanism 5 adopts a double-safety design. Under normal conditions, the pawl 503, under the action of the first torsion spring 504, tightly bites the tooth groove of the ratchet 501, preventing the lead screw from rotating accidentally. When adjustment is required, the outer connecting bracket 507 compresses the spring 509, and through the transmission of the rack 506-gear 505, forces the pawl 503 to disengage from the ratchet 501. At the same time, the insert block 510 is inserted into the insert bracket 512 to form a temporary fixation. At this time, the first bidirectional lead screw 404 or the second bidirectional lead screw 406 can rotate freely. After the connecting bracket 507 is released, the spring 509 and the first torsion spring 504 drive all components to reset, automatically restoring the locked state and ensuring structural stability.

[0028] In this embodiment, precise control is achieved through a bidirectional lead screw system. When the first bidirectional lead screw 404 is rotated, it drives the two sets of first adjusting rods 403 to move synchronously in opposite directions, thereby driving the corresponding positioning block 402 to slide along a straight line; similarly, the second bidirectional lead screw 406 controls the displacement of the other two sets of positioning blocks 402. The four sets of positioning blocks 402 work together to insert into or exit the positioning slots 401 of the mounting frame 3, completing the clamping and fixing or quick release of the heat sink 2. The entire process requires no auxiliary tools. The locking mechanism 5 adopts a double safety design. Under normal conditions, the pawl 503 bites the tooth groove of the ratchet 501 under the action of the first torsion spring 504, preventing the lead screw from rotating accidentally; when adjustment is required, the outer pull connecting frame 507 compresses the spring 509, and through the rack 506-gear 505 transmission, forces the pawl 503 to disengage from the ratchet 501, while the insert block 510 is inserted into the insert frame 512 to form a temporary fixation. At this time, the first bidirectional lead screw 404 or the second bidirectional lead screw 406 can rotate freely. After the connecting frame 507 is released, the spring 509 and the first torsion spring 504 drive each component to reset and automatically restore the locked state, ensuring structural stability.
