Description

Technical Field

[0001] This utility model relates to the field of fan power supply box technology, and in particular to a fan power supply box mounting structure. Background Technology

[0002] The fan's power supply box (also known as a power module or power controller) is the core component of the fan system, responsible for providing a stable power supply to the fan and controlling its operating status (such as speed, start / stop, etc.). The location design of the power supply box has a significant impact on the overall layout of the equipment, heat dissipation efficiency, and ease of installation. Typically, the power supply box needs to be installed close to the fan to reduce cable length and optimize power transmission efficiency. Given the limited internal space of electronic equipment, the installation structure of the power supply box must be compact and not affect the layout of other components. At the same time, the limited space within the power supply box needs to be fully utilized, and all wiring within the power supply box must be clearly defined.

[0003] During the installation of the fan power supply box, the fan will vibrate when it is running. Therefore, the power supply box needs to be securely installed on the fan. At the same time, the pulled-in power cord needs to be quickly clamped and restrained. Otherwise, the power cord will be pulled out of the power supply box. Utility Model Content

[0004] This disclosure relates to a fan power supply box mounting structure, which effectively reduces vibration transmission and maintains stable and quiet operation of the equipment by fixing it with bolts on the side plate and screws on the ear plate. The stable installation of the power supply box can prevent it from falling off or loosening when the fan is running. The fan will vibrate when it runs. If the power supply box is not firmly installed, it may cause noise or even displacement due to vibration. The two limiting blocks can also quickly clamp and restrict the wires inserted in the power supply box. The limiting blocks can quickly fix the wires and ensure that the wires will not easily loosen or fall off during installation. The wires cannot be disconnected from the power supply box even if they are pulled. The clamping design of the limiting blocks can effectively prevent the wires from falling out of the power supply box and avoid accidental power failure or equipment failure.

[0005] In a first aspect, this disclosure provides a fan power supply box mounting structure, specifically including: a fan; a power supply box is fixedly mounted on the right side wall of the fan, and a through-hole is provided at the left end of the power supply box; a through-hole for the main cable is provided in the middle of the right end of the power supply box; a row of through-holes is provided at the upper end of the right side wall of the power supply box; two threaded grooves are provided at the bottom of the inner cavity of the power supply box; a snap-fit ​​sealing cover is installed at the upper port of the power supply box; and through screws are rotatably inserted at the four corners of the sealing cover.

[0006] Two through-hole spring rods are inserted into the two rod holes at the left end of the power box; baffles are fixedly installed on the opposite ends of the two spring rods, and pull rings are fixedly installed on the outer sides of the two baffles; connecting plates are fixedly installed on the opposite ends of the two spring rods; hemispherical limiting blocks are fixedly installed on the side walls of the two connecting plates, and through arc-shaped slots are opened on the opposite ends of the two limiting blocks; three guide rods are fixedly installed on the side walls of the opposite ends of the two connecting plates.

[0007] In at least some embodiments, a slot is provided at the bottom of the inner cavity of the power supply box, and three through guide holes are provided at the front and rear ends of the power supply box, respectively.

[0008] In at least some embodiments, a sealing groove is provided at the upper edge of the power box, a side plate is fixedly installed at the bottom of the left end of the power box, and a row of through bolts is rotatably inserted into the side plate. Two ear plates are fixedly installed at the left ends of the front and rear ends of the power box, and through screws are rotatably inserted into the ear plates.

[0009] In at least some embodiments, a support frame is fixedly installed in a slot at the bottom of the power supply box, and a stabilizing strip is fixedly installed at the lower end of the support frame, with through bolts rotatably inserted at both ends of the stabilizing strip.

[0010] In at least some embodiments, a row of bearing grooves is provided at the upper end of the support frame, and an arc-shaped extension plate is fixedly installed at the bearing groove.

[0011] In at least some embodiments, a sealing strip is fixedly installed at the edge of the bottom of the sealing cover, and a limiting plate is fixedly installed at the bottom of the sealing cover, with a row of limiting grooves formed at the bottom of the limiting plate.

[0012] This utility model provides a fan power supply box mounting structure, which has the following beneficial effects:

[0013] In this utility model, the power supply box, when in use, can effectively reduce vibration transmission by being fixed with bolts on the side plate and screws on the ear plate, maintaining the stability and quietness of the equipment operation. The stable installation of the power supply box can prevent it from falling off or loosening when the fan is running. The fan will generate vibration when running, and if the power supply box is not firmly installed, it may cause noise or even displacement due to vibration. The two limiting blocks can also quickly clamp and restrict the wires inserted in the power supply box. The limiting blocks can quickly fix the wires, ensuring that the wires will not easily loosen or fall off during installation. The wires cannot be disconnected from the power supply box even if pulled. The clamping design of the limiting blocks can effectively prevent the wires from coming loose from the power supply box, avoiding accidental power outages or equipment failures.

[0014] By clamping the wire with the arc-shaped slots of two limiting blocks, the left side walls of the two limiting blocks adhere to the side wall of the wire plug, providing a stable restraint. This prevents the wire from moving to the right and breaking off from the fan when pulled to the right. The arc-shaped slot design of the limiting blocks ensures a tight fit against the wire surface, guaranteeing a secure clamping. This clamping method effectively prevents the wire from slipping or loosening, improving connection reliability. The left side wall of the limiting blocks closely adheres to the side wall of the wire plug, forming a blocking mechanism. This design effectively prevents the wire from breaking off from the fan, ensuring the normal operation of the electrical equipment. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1 to 4 :

[0026] This utility model proposes a fan power supply box installation structure, including: a fan 1; a power supply box 2 fixedly installed on the right side wall of the fan 1, and a through-hole is opened at the left end of the power supply box 2; a through-hole for the main wire is opened in the middle of the right end of the power supply box 2; a thicker wire passes through the main wire hole at the right end of the power supply box 2 and connects to the fan 1; a row of through-holes is opened at the upper end of the right side wall of the power supply box 2; a thinner branch wire passes through the through-holes at the right end of the power supply box 2; two threaded grooves are opened at the bottom of the inner cavity of the power supply box 2; a snap-fit ​​sealing cover 3 is installed at the upper port of the power supply box 2; through screws are rotatably inserted at the four corners of the sealing cover 3; after the wires in the power supply box 2 are connected, the sealing cover 3 is used to seal the upper port of the power supply box 2. When closed, first insert the sealing strip 301 into the sealing groove 203, then rotate the screw on the sealing cover 3 and insert it into the upper end of the power box 2, temporarily fixing the sealing cover 3 to the power box 2. The sealing cover 3 will not move when touched, thus sealing the upper part of the power box 2 and preventing external debris from entering the power box 2. The sealing strip 301 is fixedly installed on the bottom edge of the sealing cover 3, and the limiting plate 302 is fixedly installed on the bottom of the sealing cover 3. The bottom of the limiting plate 302 has a row of limiting grooves 303. The sealing strip 301 is inserted into the sealing groove 203. At this time, the bottom of the limiting plate 302 will be in contact with the upper end of the support frame 205, and the limiting grooves 303 will be in contact with the bearing groove 205. 7. A circular hole is formed by the connection. The limiting groove 303 presses down on the branch wire at the bearing groove 207 to restrict it. In this way, the branch wires entering the power box 2 are clamped and restricted by multiple limiting grooves 303 and bearing grooves 207, making the distribution of branch wires in the power box 2 clear. The multiple branch wires are spaced apart to prevent them from getting tangled. Two through spring rods 4 are inserted into the two rod holes at the left end of the power box 2. The two spring rods 4 are fixedly installed with baffles 401 at their opposite ends. Pull rings are fixedly installed on the outer sides of the two baffles 401. When the wires in the power box 2 are connected to the fan 1, the pull rings on the two baffles 401 are grasped and the two connecting plates 402 are moved in opposite directions. The connecting plates 402 will squeeze the springs on the spring rods 4. When the fan is retracted, the two limiting blocks 403 will move in opposite directions. Then, the wire entering the power box 2 is inserted into the fan 1 and connected. Next, the two pull rings are released so that the springs on the two spring rods 4 push the connecting plate 402 and the limiting block 403 in opposite directions. The arc-shaped slots of the two limiting blocks 403 clamp the wire. At this time, the left side wall of the two limiting blocks 403 will stick to the side wall of the wire plug to stabilize and restrict it. At this time, the wire will not move to the right and break off from the fan 1 when pulled to the right. The connecting plate 402 is fixedly installed on the opposite end of the two spring rods 4 respectively. The side wall of the two connecting plates 402 is fixedly installed with hemispherical limiting blocks 403 respectively, and the opposite end of the two limiting blocks 403 is provided with through arc-shaped slots.When the power plug is inserted between the two hemispherical limiting blocks 403, the two limiting blocks 403 will move backwards due to the pressure from the power plug. After the two limiting blocks 403 move towards each other and align, the arc-shaped slots at opposite ends of the two limiting blocks 403 will align to form a circular hole. Three guide rods 404 are fixedly installed on the side walls at opposite ends of the two connecting plates 402. The guide rods 404 slide through the guide holes 202. When the connecting plates 402 slide back and forth, the guide rods 404 are restricted by the guide holes 202, and the connecting plates 402 can only slide back and forth, preventing the connecting plates 402 from shifting or tilting during the back and forth sliding. This would prevent the two limiting blocks 403 on the two connecting plates 402 from aligning smoothly.

[0027] The power supply box 2 has a slot 201 at the bottom of its inner cavity, three through guide holes 202 at its front and rear ends, a sealing groove 203 at the upper edge, and a side plate 204 fixedly installed at the bottom left end. A row of through bolts is rotatably inserted into the side plate 204, which is then rotated and inserted into the fan 1 to secure the side plate 204 and the power supply box 2, preventing it from falling off when touched. Two ear plates are fixedly installed at the left ends of both the front and rear ends of the power supply box 2, with through screws rotatably inserted into them. These screws are then rotated and inserted into the fan 1 to secure the ear plates and the power supply box 2, again preventing it from falling off when touched. This multi-layered securing system ensures that the power supply box 2 remains secure. To prevent the power supply box 2 from falling off the fan 1, a support frame 205 is fixedly installed at the slot 201 at the bottom of the power supply box 2. A stabilizing strip 206 is fixedly installed at the lower end of the support frame 205. Bolts are inserted through both ends of the stabilizing strip 206 and rotated into the threaded grooves at the bottom of the inner cavity of the power supply box 2. This fixes and restricts the stabilizing strip 206 and the support frame 205, preventing the support frame 205 from tilting when touched. The bearing groove 207 at the upper end of the support frame 205 can stably support the branch lines. A row of bearing grooves 207 is opened at the upper end of the support frame 205. The bearing grooves 207 support the branch lines in the power supply box 2. An arc-shaped extension plate 208 is fixedly installed at the bearing groove 207. The arc-shaped groove at the upper end of the extension plate 208 supports and restricts the branch lines.

[0028] Example 2, based on Example 1, such as Figure 1 and Figure 4As shown, a support frame 205 is fixedly installed in slot 201 at the bottom of the power supply box 2, and a stabilizing strip 206 is fixedly installed at the lower end of the support frame 205. Through bolts are inserted into both ends of the stabilizing strip 206. Remove the stabilizing strip 206 and the bolts, and then fix the lower end of the support frame 205 to the bottom of the inner cavity of the power supply box 2 to stabilize and restrict the support frame 205. In this way, the support frame 205 will not tilt when touched, avoiding the bolts from loosening and failing to stabilize the support frame 205 after long-term use, and also saving on component costs.

[0029] The working principle of this embodiment is as follows: When using the power supply box 2, when the wire is connected to the fan 1, grasp the pull rings on the two baffles 401 and move the two connecting plates 402 in opposite directions. The connecting plates 402 will compress the springs on the spring rods 4. At this time, the two limiting blocks 403 will also move in opposite directions. Then, insert the wire into the power supply box 2 and connect it to the fan 1. Next, release the two pull rings so that the springs on the two spring rods 4 push the connecting plates 402 and the limiting blocks 403 in opposite directions. The arc-shaped slots of the two limiting blocks 403 clamp the wire. At this time, the left side wall of the two limiting blocks 403 will adhere to the side wall of the wire plug to stabilize and restrict it. At this time, when the wire is pulled to the right, it will not move to the right and disconnect from the fan 1. After the wire in the power supply box 2 is connected, when the sealing cover 3 is used to seal the upper port of the power supply box 2, first Insert the sealing strip 301 into the sealing groove 203. At this time, the bottom of the limiting plate 302 will be in contact with the upper end of the support frame 205. Simultaneously, the limiting groove 303 will align with the bearing groove 207 to form a round hole. The limiting groove 303 will press down and restrict the branch lines at the bearing groove 207. In this way, the branch lines entering the power box 2 are clamped and restricted by multiple limiting grooves 303 and bearing grooves 207, making the distribution of branch lines entering the power box 2 clear. The multiple branch lines are spaced apart to prevent them from getting tangled. Then, rotate the screw on the sealing cover 3 and insert it into the upper end of the power box 2. The sealing cover 3 is temporarily fixed on the power box 2. When the sealing cover 3 is touched, it will not move. In this way, the sealing cover 3 can seal the upper port of the power box 2 to prevent external debris from entering the power box 2.
