[0037] In summary, this invention achieves rapid cooling by setting up a heat dissipation unit to blow air onto the circuit board.

The circuit modules can be easily installed and disassembled by snap-fit, reducing the workload of workers and improving efficiency.

[0038] Example 2

[0039] Reference Figures 1-10 This is the second embodiment of the present invention. This embodiment provides a mounting and fixing device for circuit modules of CPE equipment, which includes a heat dissipation unit 100 and a fixing unit 200. The heat dissipation unit 100 and the fixing unit 200 cooperate to fix the circuit board 102a and clamp the circuit module 202c. The movable circuit module 202c is snapped into the circuit board 102a, which is convenient for assembly and disassembly. The air blown by the heat dissipation unit 100 can quickly cool down the circuit board 102a and improve its service life.

[0040] Specifically, the heat dissipation unit 100 includes a support assembly 101, a circuit board assembly 102 disposed on the top of the support assembly 101, and a heat dissipation assembly 103 disposed on one side of the inner wall of the support assembly 101.

[0041] The fixing unit 200 includes a fixing component 201 disposed on one side of the inner wall of the support component 101, a movable clamping component 202 disposed on the top of the circuit board assembly 102, and two sets of double fixing components 203 disposed at both ends of the movable clamping component 202.

[0042] Furthermore, the support assembly 101 includes a support box 101a, a heat dissipation plate 101b disposed at the bottom of the support box 101, a plurality of heat dissipation holes 101c disposed on one side of the heat dissipation plate 101b, two sets of support blocks 101d disposed at the top of the heat dissipation plate 101b, an L-shaped positioning baffle 101e disposed on one side of the support block 101d, a sliding pressing groove 101f disposed on one side of the support box 101a, four sets of sliding grooves 101g symmetrically disposed on the inner wall of the support box 101a, an insertion hole 101h disposed on one side of the support box 101a, and a fixed support plate 101i disposed on one side of the insertion hole 101h.

[0043] Furthermore, the circuit board assembly 102 includes a circuit board 102a, a connecting block 102b disposed on one side of the circuit board 102a, a support plate 102c disposed on the top of the connecting block 102b, and two sets of first elastic locking blocks 102d disposed on the top of the support plate 102c.

[0044] Furthermore, the heat dissipation assembly 103 includes a rotating shaft 103a, a drive motor 103b disposed on one side of the rotating shaft 103a, a rotating handle 103c fixedly connected to one end of the rotating shaft 103a, a first gear 103d fixedly connected to one end of the rotating shaft 103a, two sets of second gears 103e meshing with both sides of the first gear 103d, a fixed shaft 103f movably connected to one side of the second gear 103e, a connecting column 103g fixedly connected to one side of the second gear 103e, and three sets of fan blades 103h fixedly connected to one side of the connecting column 103g.

[0045] Furthermore, the fixing component 201 includes two sets of fixing connecting blocks 201a, fixing posts 201b whose two ends are fixedly connected to one side of the two sets of fixing connecting blocks 201a respectively, a compression plate 201c movably connected to the fixing post 201b, and compression springs 201d whose two ends are fixedly connected to the top of the compression plate 201c and the inner wall of the support box 101a respectively.

[0046] Furthermore, the movable clamping assembly 202 includes a bidirectional lead screw 202a, two sets of clamping plates 202b threadedly connected to the bidirectional lead screw 202a, a circuit module 202c disposed on the top of the fixed support plate 101i, a support connecting plate 202d fixedly connected to one side of the circuit module 202c, two sets of second elastic locking blocks 202e fixedly connected to the top of the support connecting plate 202d, a transverse connecting plate 202f fixedly connected to one side of the circuit module 202c, a locking block 202g fixedly connected to the bottom of the transverse connecting plate 202f, a limiting block 202h connected to one side of the bidirectional lead screw 202a, and a rotating column 202i fixedly connected to one end of the bidirectional lead screw 202a.

[0047] Preferably, rotating the rotating column 202i drives the bidirectional lead screw 202a to rotate, causing the two sets of clamping plates 202b, which are threaded to both ends of the bidirectional lead screw 202a, to move towards the center through the threads in different directions at both ends of the bidirectional lead screw 202a, thus clamping the circuit module 202c. Pulling the rotating column 202i drives the bidirectional lead screw 202a to move simultaneously within the sliding pressing groove 101f. The clamped circuit module 202c moves simultaneously with the bidirectional lead screw 202a. When it moves to the first pressing port of the sliding pressing groove 101f, it presses the rotating column 202i, causing the clamped circuit module 202c to move towards the center with the bidirectional lead screw 202a. During the downward movement, the locking block 202g contacts the two sets of first elastic locking blocks 102d. By squeezing the locking block 202g, it is locked into the first locking groove M in the two sets of first elastic locking blocks 102d. The rotating column 202i rotates in the opposite direction, causing the bidirectional lead screw 202a to rotate in the opposite direction. This causes the two sets of clamping plates 202b, which are threaded to both ends of the bidirectional lead screw 202a, to move to both sides through the threads in different directions at both ends of the bidirectional lead screw 202a. This releases the clamping of the circuit module 202c. The rotating column 202i is pulled to drive the bidirectional lead screw 202a to move simultaneously in the sliding pressing groove 101f until it moves to the initial position.

[0048] Furthermore, the dual fixing assembly 203 includes a threaded plate 203a threadedly connected to the bidirectional lead screw 202a, a T-shaped plug block 203b fixedly connected to the bottom of the threaded plate 203a, a plug plate 203c plugged into the T-shaped plug block 203b, a first L-shaped fixing plate 203d disposed at the bottom of the plug plate 203c, a first telescopic sleeve rod 203e fixedly connected to one side of the first L-shaped fixing plate 203d, a first telescopic rod 203f movably connected to the first telescopic sleeve rod 203e, a connecting rod 203g fixedly connected to the plug plate 203c, and a fixing member 203h fixedly connected to one end of the connecting rod 203g.

[0049] Furthermore, the fastener 203h includes a second L-shaped fixing plate 203h-1, a compression spring 203h-2 fixedly connected to one side of the second L-shaped fixing plate 203h-1, a telescopic fixing plate 203h-3 fixedly connected to one side of the compression spring 203h-2, a second telescopic sleeve rod 203h-4 fixedly connected to one side of the second L-shaped fixing plate 203h-1, and a first telescopic rod 203f movably connected to the second telescopic sleeve rod 203h-4.

[0050] Furthermore, the second L-shaped fixing plate 203h-1 is fixedly connected to one end of the connecting rod 203g, the bidirectional screw 202a is set in the sliding pressing groove 101f, and the first telescopic rod 203f and the second telescopic rod 203h-5 are both set in the sliding groove 101g.

[0051] Furthermore, the first snap-fit ​​groove M between the snap-fit ​​block 202g and the two sets of first elastic snap-fit ​​blocks 102d and the second snap-fit ​​groove N between the two sets of second elastic snap-fit ​​blocks 202e are both compatible.

[0052] It should be noted that rotating the rotating column 202i drives the two sets of threaded plates 203a, which are driven by the threads at both ends of the bidirectional lead screw 202a in different directions, causing the two sets of threaded plates 203a to move towards the center, clamping the circuit board 102a. Furthermore, when the circuit board 102a is not in the correct mounting position, the first L-shaped fixing plate 203d and the second L-shaped fixing plate 203h-1 push the contacting circuit board 102a, positioning it in the correct mounting position and providing initial fixation to prevent the circuit board 102a from shifting and causing damage to the circuit module 202. When assembly of c fails, pulling the rotating column 202i causes the bidirectional lead screw 202a to move simultaneously within the sliding pressing groove 101f. The first telescopic rod 203f and the second telescopic rod 203h-5 both slide forward within the sliding groove 101g. When the two sets of threaded plates 203a and plug-in plates 203c lose their connection, the first telescopic rod 203f and the second telescopic rod 203h-5 are at the bottom of the sliding groove 101g, supporting the double fixing assembly 203. At the same time, the plug-in plate 203c is at the top of the circuit board 102a, further supporting the double fixing assembly 203 and doubly fixing the circuit board 102a.

[0053] In use, this invention has five steps. The first step is to initially limit and fix the circuit board 102a. Pull the extrusion plate 201c so that the extrusion plate 201c rotates around the fixing post 201b. During the rotation, the extrusion spring 201d is compressed, causing the extrusion spring 201d to contract under force. The circuit board 102a is placed on the two sets of support blocks 101d, with one side tightly against the L-shaped positioning baffle 101e. Release the extrusion plate 201c, and the extrusion spring 201d loses its extrusion force, pushing the extrusion plate 201c to rotate around the fixing post 201b until it is tightly against the circuit board 102a, thus initially fixing the circuit board 102a.

[0054] The second step involves doubly securing circuit board 102a and placing it in the designated position. Rotating the rotating column 202i drives two sets of threaded plates 203a, which are then moved towards the center by the threads at both ends of the bidirectional lead screw 202a, clamping circuit board 102a. When circuit board 102a is not in the correct mounting position, the first L-shaped fixing plate 203d and the second L-shaped fixing plate 203h-1 push the contacting circuit board 102a, positioning it correctly and providing initial fixation to prevent the circuit board from slipping out of the mounting position. The misalignment of 102a causes the assembly failure of circuit module 202c. Pulling the rotating column 202i drives the bidirectional lead screw 202a to move simultaneously within the sliding pressing groove 101f. The first telescopic rod 203f and the second telescopic rod 203h-5 both slide forward within the sliding groove 101g. When the two sets of threaded plates 203a and plug-in plates 203c lose their connection, the first telescopic rod 203f and the second telescopic rod 203h-5 are at the top of the sliding groove 101g, supporting the double fixing component 203. At the same time, the plug-in plate 203c is at the top of the circuit board 102a, further supporting the double fixing component 203 and doubly fixing the circuit board 102a.

[0055] The third step involves clamping and assembling the circuit module 202c. Rotating the rotating column 202i drives the bidirectional lead screw 202a to rotate, causing the two sets of clamping plates 202b, threaded to both ends of the bidirectional lead screw 202a, to move towards the center via the threads in different directions at both ends of the bidirectional lead screw 202a, thus clamping the circuit module 202c. Pulling the rotating column 202i moves the bidirectional lead screw 202a simultaneously within the sliding pressing groove 101f. The clamped circuit module 202c moves along with the bidirectional lead screw 202a. When it reaches the first pressing port of the sliding pressing groove 101f, it presses the rotating column 202i, causing the clamped circuit module 202c to follow... The bidirectional lead screw 202a moves downward. During the downward movement, the locking block 202g contacts the two sets of first elastic locking blocks 102d. By squeezing the locking block 202g, it locks into the first locking groove M in the two sets of first elastic locking blocks 102d. The rotating column 202i rotates in the opposite direction, causing the bidirectional lead screw 202a to rotate in the opposite direction. This causes the two sets of clamping plates 202b, which are threaded to both ends of the bidirectional lead screw 202a, to move to both sides through the threads in different directions at both ends of the bidirectional lead screw 202a. This releases the clamping of the circuit module 202c. The rotating column 202i is pulled to drive the bidirectional lead screw 202a to move simultaneously in the sliding pressing groove 101f until it moves to the initial position.

[0056] The fourth step involves assembling several sets of circuit modules 202c. After the first set of circuit modules 202c is installed, the rotating column 202i is pulled to drive the bidirectional lead screw 202a into the groove at the top of the sliding pressing groove 101f. The rotating column 202i is then pushed forward to make the bidirectional lead screw 202a follow the movement. As the bidirectional lead screw 202a continues to move forward, the first L-shaped fixing plate 203d is tightly fitted against the circuit board 102a and the support block 101d, limiting its movement. The T-shaped plug-in block 203b, fixedly connected to the bottom of the threaded plate 203a, moves within the T-shaped plug-in groove of the plug-in plate 203c until the T-shaped plug-in... When the connector 203b is completely disengaged from the T-shaped insertion slot, the first telescopic rod 203f and the second telescopic rod 203h-5 slide at the bottom within the sliding groove 101g, supporting the double fixing component 203. At the same time, the insertion plate 203c is on top of the circuit board 102a, further supporting the double fixing component 203 and doubly fixing the circuit board 102a. Pulling the rotating column 202i drives the bidirectional lead screw 202a back to its initial position within the sliding pressing groove 101f. Repeating the above steps assembles multiple sets of circuit modules 202c, making the modular assembly of the circuit modules 202c convenient and quick.

[0057] The fifth step involves rapid heat dissipation. Turning on the drive motor 103b causes the rotating shaft 103a to rotate. Simultaneously, the first gear 103d, fixedly connected to one end of the rotating shaft 103a, rotates, causing the two sets of second gears 103e meshing with both sides of the first gear 103d to rotate around the fixed shaft 103f. This, in turn, causes the three sets of fan blades 103h fixedly connected to one side of the connecting post 103g to rotate, rapidly blowing air onto the circuit board 102a and circuit module 202c to prevent overheating and protect the finished product. The assembly position is closest to the fan blade 103h. Modular assembly at this position can achieve the maximum cooling effect and prevent excessive heat generated by the circuit board 102a and circuit module 202c. The second gear 103e can be modularly assembled to further improve heat dissipation efficiency. The blown hot air is discharged through the heat dissipation hole 101c, ensuring that the circuit board 102a and circuit module 202c are always in a suitable assembly environment. To prevent the drive motor 103b from failing and not being able to dissipate heat in time, the handle 103c can be turned to replace the drive motor 103b to achieve the same cooling effect, ensuring the quality of the product and reducing maintenance costs.

[0058] In summary, this invention achieves rapid cooling by setting up a heat dissipation unit to blow air onto the circuit board. By setting up a fixing unit, the circuit can be kept fixed, and the movable circuit modules can be clamped for modular assembly. The circuit modules can be easily installed and disassembled by snap-fit, reducing the workload of workers and improving efficiency.
