Description

Technical Field

[0001] The present application relates to the technical field of outgoing line protection, and in particular to an outgoing line protection structure of a metal housing of an LED power supply. Background Art

[0002] With the continuous advancement of LED power supply technology, metal casings have become widely used in LED power supply packaging due to their excellent heat dissipation, mechanical strength, and electromagnetic shielding properties. However, the cable outlet on the metal casing has become a critical part of the power supply's operation, and the need for a protective structure has emerged. Early metal casing cable outlet protection structures were relatively simple, only meeting basic power cable routing requirements. However, with increasing demands for power supply safety, stability, and ease of use, more complex and optimized cable outlet protection structures have gradually emerged.

[0003] The traditional LED power supply metal casing wire outlet protection structure has a simple wire outlet design and unprocessed sharp cuts, which makes the power cord easily cut through the outer casing, causing the risk of leakage, endangering personal safety and equipment operation. At the same time, the traditional structure lacks an effective adjustment mechanism for power cord length management and cannot flexibly adapt to different needs, resulting in the power cord being tangled or insufficient in length. Therefore, this patent needs to be upgraded and modified based on the existing technology. Utility Model Content

[0004] In response to the shortcomings of the existing technology, this application provides a metal casing wire outlet protection structure for an LED power supply, which overcomes the shortcomings of the existing technology and aims to solve the problem that the traditional metal casing wire outlet protection structure of an LED power supply has a simple wire outlet design and unprocessed sharp cuts, which makes the power cord easily cut through the outer skin, causing the risk of leakage, endangering personal safety and equipment operation. At the same time, the traditional structure lacks an effective adjustment mechanism for power cord length management and cannot flexibly adapt to different needs, resulting in the problem of power cords being tangled or insufficient in length.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a metal shell wire outlet protection structure for an LED power supply, comprising an outer box body, an upper cover and a wire bundle structure, a wire outlet is provided at the top position of the outer side of the outer box body, wherein the edge of the wire outlet is rolled inward, the upper cover is buckled on the top of the outer box body, and an upper cover notch is provided at the outer side of the upper cover, wherein the area of ​​the upper cover notch is larger than the area of ​​the wire outlet, and the upper opening of the upper cover notch is folded inward. When the upper cover is buckled on the top of the outer box body, the upper opening of the upper cover notch is just erected at the top position of the wire outlet, a power cord is provided inside the outer box body, the power cord passes through the wire outlet and extends to the outside, a wire bundle structure is fixedly provided at the lower end position of the wire outlet inside the outer box body, and the power cord inside the outer box is connected to the internal equipment after passing through the wire bundle structure.

[0006] By adopting the above technical solution, the wire outlet adopts a tearing method and performs a curling treatment. This curling treatment effectively avoids the sharp edges of the incision, greatly reducing the risk of the power cord outer skin being cut, thereby preventing the risk of leakage caused by damage to the power cord outer skin. The incision position of the upper cover notch position is also curled to avoid the power cord being cut by the sharp incision inside the upper cover notch during swinging or installation. Since the area of ​​the upper cover notch is larger than the area of ​​the wire outlet, after the upper cover is buckled on the top of the outer box, the side edge of the upper cover notch is located outside the wire outlet, thereby avoiding the side edge of the upper cover notch scratching the power cord outer skin, ensuring the stability and safety of the circuit connection. When the power cord extends too long from the outside of the outer box, the power cord can be bundled by the wire bundling structure, while preventing the power cord from being separated from the internal equipment of the outer box when it is subjected to external pulling force.

[0007] As a preferred technical solution of the present application, fixed blocks are fixedly connected to both sides of the bottom of the outer box body, and mounting holes are provided inside the fixed blocks.

[0008] By adopting the above technical solution, the outer box body can be fixed by the fixing block.

[0009] As a preferred technical solution of the present application, the cable harness structure includes a rotary damper and a power cord. One side of the rotary damper is fixedly connected to a cable harness wheel, and the power cord is wound around the outside of the cable harness wheel.

[0010] By adopting the above technical solution, one end of the power cord is connected to the inside of the cable tie wheel, and the rotation of the power cord drives the power cord to be wound around the outside of the cable tie wheel. The setting of the rotary damper ensures that the power cord can rotate and stop at any time according to demand. In this way, when the power cord is too long outside, it can be wound and collected by rotating the cable tie wheel. When the length of the power cord required outside is not enough, the power cord wound around the outside of the cable tie wheel can be released by rotating in the opposite direction.

[0011] As an optimal technical solution of the present application, a connecting piece is fixedly connected to the outside of the rotary damper, a connecting hole is provided inside the connecting piece, and a fixing bolt is fixedly connected to the inner wall of the outer box at the position of the connecting hole. The fixing bolt passes through the connecting piece and is threadedly connected to a fixing nut on the outside.

[0012] By adopting the above technical solution, the rotary damper is fixed to the inner wall of the outer box body by means of a fixing nut.

[0013] As a preferred technical solution of the present application, a clamping opening is provided on the outer side of the cable pulley, a hinge is fixedly connected to the clamping opening, and a clamping block is rotatably connected to the outer side of the hinge.

[0014] By adopting the above technical solution, there is a gap for the wire to come out after the clamping block covers the inside of the clamping mouth. The gap adopts an oblique design and the gap just clamps the power cord. When the clamping block covers the inside of the clamping mouth, the power cord can be tightened and fixed to prevent the power cord from moving inside the cable pulley when it is subjected to external pulling force.

[0015] As a preferred technical solution of the present application, latch tongues are provided on both sides of the clamping block, and latch grooves are provided on both sides of the clamping opening at positions corresponding to the latch tongues.

[0016] By adopting the above technical solution, when the power cord is installed, the clamping block can be pressed to disengage the tongue and the slot, and then rotated around the hinge toward the inside of the cable pulley. At this time, the power cord can be introduced into the cable pulley through the clamping opening, and then the clamping block is pushed to rotate around the hinge until the slot is embedded in the tongue, thereby achieving the fastening and fixation of the clamping block.

[0017] As a preferred technical solution of the present application, a side cover is fixedly connected to the outer side of the cable pulley, and a crank is rotatably connected to one end of the side cover.

[0018] By adopting the above technical solution, the convenience of operation is increased by setting the crank handle. The staff can hold the crank handle and rotate it around the outline direction of the cable wheel to drive the cable wheel to rotate, thereby realizing the collection and release of the power line by the cable wheel.

[0019] As a preferred technical solution of the present application, a wire outlet groove is provided on the inner wall of the outer box at the position of the rotary damper.

[0020] By adopting the above technical solution, the power cord inside the cable tie reel can be led out from the cable tie reel through the cable outlet slot, and then the end of the power cord can be connected to the equipment inside the outer box.

[0021] Beneficial effects of this application:

[0022] 1. In the present invention, the edge of the outlet is rolled inwards. This curling method effectively avoids the sharp edges of the cut, greatly reducing the risk of the outer sheath of the power cord being cut. The notch cut of the upper cover is curled, and the area of ​​the notch of the upper cover is larger than the area of ​​the outlet. After the upper cover is buckled, the side edge of the notch of the upper cover is located outside the outlet, avoiding the power cord being cut or scratched by the sharp cut inside the notch of the upper cover during swinging or installation, thereby preventing the risk of leakage caused by damage to the power cord sheath, ensuring the personal safety of the user and the normal operation of the equipment. In daily use, the equipment may cause friction between the power cord and the edge of the outlet due to movement, vibration, etc. The curling process can effectively prevent the wire sheath from being cut and causing leakage accidents.

[0023] 2. In this utility model, the rotary damper and the cable pulley in the cable harness structure work together to conveniently tighten and release the power cord via a crank operation. When the required power cord length is insufficient, the crank is rotated in the reverse direction to release the cord; when the cord is too long, the crank is rotated in the forward direction to tighten it. The rotary damper ensures that the power cord can be rotated and stopped at any time as needed, maintaining the cord at the appropriate length, preventing the cord from becoming tangled around the device and reducing the impact of cord entanglement and other issues that affect device use.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] Reference Figure 1-7, a metal shell wire outlet protection structure for LED power supply, including an outer box body 1, an upper cover 2 and a wire harness structure, a wire outlet 3 is provided at the top position of the outer side of the outer box body 1, wherein the edge position of the wire outlet 3 is rolled inward, the upper cover 2 is buckled on the top of the outer box body 1, and a upper cover notch 4 is provided at the outer side of the upper cover 2, wherein the area of ​​the upper cover notch 4 is larger than the area of ​​the wire outlet 3, and the upper end of the upper cover notch 4 is folded inward. When the upper cover 2 is buckled on the top of the outer box body 1, the upper end of the upper cover notch 4 is just erected at the top position of the wire outlet 3, a power cord 6 is provided inside the outer box body 1, the power cord 6 passes through the wire outlet 3 and extends to the outside, a wire harness structure is fixedly provided at the lower end position of the wire outlet 3 inside the outer box body 1, the power cord 6 inside the outer box body 1 is connected to the internal equipment after passing through the wire harness structure, and the wire outlet 3 is torn and rolled. The curling treatment effectively avoids the sharp edges of the incision, greatly reducing the risk of the outer skin of the power cord 6 being cut, thereby preventing the risk of leakage caused by damage to the skin of the power cord 6. The incision position of the upper cover notch 4 of the upper cover 2 is also curled to prevent the power cord 6 from being cut by the sharp incision inside the upper cover notch 4 during swinging or installation. Since the area of ​​the upper cover notch 4 is larger than the area of ​​the wire outlet 3, after the upper cover 2 is buckled on the top of the outer box 1, the side edge of the upper cover notch 4 is located outside the wire outlet 3, thereby preventing the side edge of the upper cover notch 4 from scratching the skin of the power cord 6, ensuring the stability and safety of the circuit connection. When the power cord 6 extends too long from the outside of the outer box 1, the power cord 6 can be bundled by the wire bundling structure, while preventing the power cord 6 from being separated from the internal equipment of the outer box 1 when subjected to external pulling force.

[0034] In this embodiment, if Figure 1 - Figure 7 As shown, fixing blocks 5 are fixedly connected to both sides of the bottom of the outer box body 1 , and mounting holes are provided inside the fixing blocks 5 , through which the outer box body 1 can be fixed.

[0035] In this embodiment, if Figure 1 - Figure 7 As shown, the wiring harness structure includes a rotary damper 7 and a power cord 6, and a wiring harness wheel 8 is fixedly connected to one side of the rotary damper 7. The power cord 6 is wound around the outside of the wiring harness wheel 8, wherein one end of the power cord 6 is connected to the inside of the wiring harness wheel 8. The rotation of the power cord 6 drives the power cord 6 to be wound around the outside of the wiring harness wheel 8. The setting of the rotary damper 7 ensures that the power cord 6 can rotate and stop at any time according to demand. In this way, when the power cord 6 is too long in the outside world, it can be wound and collected by rotating the wiring harness wheel 8. When the length of the power cord 6 required by the outside world is not enough, it can be rotated in the opposite direction to release the power cord 6 wound around the outside of the wiring harness wheel 8.

[0036] In this embodiment, if Figure 1 - Figure 7As shown, a connecting piece 12 is fixedly connected to the outside of the rotary damper 7, and a connecting hole is provided inside the connecting piece 12. A fixing bolt 11 is fixedly connected to the inner wall of the outer box body 1 at the position of the connecting hole. The fixing bolt 11 passes through the connecting piece 12 and is then threadedly connected to the outside of the fixing nut 13, thereby fixing the rotary damper 7 to the inner wall position of the outer box body 1 through the fixing nut 13.

[0037] In this embodiment, if Figure 1 - Figure 7 As shown, a clamping opening 15 is provided on the outside of the cable pulley 8, and a hinge 17 is fixedly connected to the position of the clamping opening 15. A clamping block 16 is rotatably connected to the outside of the hinge 17, wherein the clamping block 16 covers the inside of the clamping opening 15 and there is a gap for the outlet of the wire. The gap adopts an oblique design, and the gap just clamps the power cord 6. When the clamping block 16 covers the inside of the clamping opening 15, the power cord 6 can be tightened and fixed, so as to prevent the power cord 6 from moving inside the cable pulley 8 when it is subjected to external pulling force.

[0038] In this embodiment, if Figure 1 - Figure 7 As shown, tongues 18 are provided on both sides of the clamping block 16, and slots 19 are provided on both sides of the clamping opening 15 at positions corresponding to the tongues 18. When the power cord 6 is installed, the clamping block 16 can be pressed to disengage the tongue 18 and the slot 19, and then rotated toward the inside of the cable wheel 8 around the hinge 17. At this time, the power cord 6 can be introduced into the cable wheel 8 through the clamping opening 15, and then the clamping block 16 can be pushed to rotate the clamping block 16 around the hinge 17 until the slot 19 is embedded in the tongue 18, thereby achieving the buckling and fixation of the clamping block 16.

[0039] In this embodiment, if Figure 1 - Figure 7 As shown, a side cover 9 is fixedly connected to the outside of the cable tie wheel 8, and a crank handle 10 is rotatably connected to one end of the side cover 9. The setting of the crank handle 10 increases the convenience of operation. The staff can hold the crank handle 10 and rotate it around the outline direction of the cable tie wheel 8 to drive the cable tie wheel 8 to rotate, thereby realizing the collection and release of the power line 6 by the cable tie wheel 8.

[0040] In this embodiment, if Figure 1 - Figure 7 As shown, a wire outlet groove 14 is provided on the inner wall of the outer box 1 at the position of the rotary damper 7. The power cord 6 inside the cable wheel 8 can be led out from the inside of the cable wheel 8 through the wire outlet groove 14, and then the end of the power cord 6 can be connected to the equipment inside the outer box 1.

[0041] Working principle: Use the fixing blocks 5 fixedly connected on both sides of the bottom of the outer box 1 for installation. Align the fixing block 5 with the installation position, and use suitable bolts or other connecting parts to fix the outer box 1 in the specified position through the installation holes inside the fixing block 5 to ensure that it is firmly installed without shaking or displacement. Press the tongues 18 on both sides of the clamping block 16 on the outside of the cable pulley 8 to disengage the tongues 18 from the slots 19 on both sides of the clamping opening 15. Then, rotate the clamping block 16 around the hinge 17 toward the inside of the cable pulley 8 to open the clamping opening 15. Introduce the power cord 6 from the outlet 3 of the outer box 1 and pass it through the upper cover slot 4 of the upper cover 2. , then lead the power cord 6 out of the cable reel 8 through the cable outlet slot 14 on the inner wall of the outer box 1, and then fix one end of it to the internal equipment of the outer box 1, push the clamping block 16 to rotate around the hinge 17 until the slot 19 is embedded in the tongue 18, so that the clamping block 16 is fastened and fixed, and the power cord 6 is tightened in the clamping port 15 to prevent it from moving in the cable reel 8, and align the connector 12 on the outside of the rotary damper 7 with the inner wall of the outer box 1 at the connection hole position, so that the fixing bolt 11 passes through the connector 12. Then, thread the fixing nut 13 on the outside of the fixing bolt 11, tighten the fixing nut 13, and firmly fix the rotary damper 7 to the inner wall of the outer box 1 to ensure that it will not loosen or move during operation. Finally, snap the upper cover 2 onto the top of the outer box 1 to complete the installation of the entire protective structure:

[0042] The curling treatment of the upper cover notch 4 and the outlet 3, as well as the design that the upper cover notch 4 is larger than the outlet 3, prevents the power cord 6 from being cut or scratched by the notch edge during swinging or slight shaking of the device, further ensuring the safety and stability of the circuit connection;

[0043] When the required length of the power cord 6 is insufficient, the operator holds the crank handle 10 at one end of the side cover 9 outside the cable tie reel 8 and rotates the crank handle 10 in the opposite direction of the cable tie reel 8. At this time, the power cord 6 can be smoothly released from the cable tie reel 8 under the action of the rotary damper 7, meeting the equipment's required length of the power cord 6.

[0044] When the power cord 6 extends too far from the outer casing 1, the crank handle 10 is held and rotated forward, and the power cord 6 is wound around the outer side of the cable tie wheel 8 for tightening. The rotary damper 7 ensures that the power cord 6 can be stopped at any time as needed, so that the power cord 6 is kept at an appropriate length, preventing the excessively long power cord 6 from becoming tangled around the device or being pulled by external forces.

[0045] During the operation of the equipment, if the power cord 6 is subjected to external pulling force, the power cord 6 will not move inside the cable wheel 8 due to the tightening and fixing effect of the clamping block 16 on the outer side of the cable wheel 8. At the same time, it also prevents the power cord 6 from being separated from the equipment inside the outer box 1, thereby ensuring the stability of the power connection and ensuring the normal operation of the equipment.

[0046] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
