Description
Technical Field
[0001] This utility model relates to the field of power adapter protection, specifically a power adapter with anti-bending function. Background Technology
[0002] A power adapter is a power conversion device for small portable electronic devices and appliances. It is generally composed of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board. Its working principle is to convert AC input to DC output. According to the connection method, it can be divided into wall plug type and desktop type, and is widely used in security cameras, set-top boxes, routers, light strips, massagers and other devices.
[0003] To improve compatibility and practicality, power adapters often feature relatively long power cords. However, these long cords can become tangled and prone to bending at the joints. Some power adapters with anti-bend features only secure the power cord connections to prevent it from wobbling. However, when the power cord is accidentally pulled, the secured connections offer poor cushioning. Strong pulling forces can damage not only the power cord but also the anti-bend structure, reducing its practicality. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, some power adapters with anti-bend functions can only simply fix the connection of the power cord to prevent it from shaking. However, when the power cord is accidentally pulled, the fixed connection has poor buffering effect. When the pulling force is large, it can easily damage the power cord and also damage the anti-bend structure, reducing its practicality. This utility model proposes a power adapter with anti-bend function.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a power adapter with anti-bending function, including a power adapter body, a connecting wire fixedly connected to one side of the power adapter body, and a wire fixing mechanism provided on one side of the power adapter body.
[0006] The cable fixing mechanism includes a ball seat, a ball head rotatably connected to the inner cavity of the ball seat, a first support rod fixed to the surface of the ball head, a second support rod slidably connected to the inner cavity of the first support rod, a cable fixing plate fixedly connected to one end of the second support rod, a cable inlet groove and a cable placement groove on one side of the cable fixing plate, the inner wall of the cable placement groove communicating with the inner wall of the cable inlet groove, an extension plate fixedly connected to one side of the cable fixing plate, a first spring fixedly connected to one side of the extension plate, and one end of the first spring fixedly connected to one side of the power adapter body.
[0007] Preferably, a positioning block is slidably connected to the inner cavity of the second support rod, and a second spring is fixedly connected to one side of the positioning block, with one end of the second spring fixedly connected to the inner wall of the second support rod.
[0008] Preferably, the surface of the first support rod is provided with a positioning hole, and the surface of the positioning block is inserted into the inner wall of the positioning hole.
[0009] Preferably, the inner wall of the cable tray is provided with a clamp plate, the clamp plate is arc-shaped, the inner wall of the clamp plate is in contact with the surface of the connecting wire, and a guide rod is fixedly connected to the surface of the clamp plate.
[0010] Preferably, one side of the fixing plate is fixedly connected to a limiting sleeve, and the surface of the guide rod is slidably connected to the inner wall of the limiting sleeve.
[0011] Preferably, the inner cavity of the wire fixing plate is rotatably connected to a bidirectional screw, and one end of the bidirectional screw is fixedly connected to an adjusting handle.
[0012] Preferably, a limiting plate is fixedly connected to the surface of the bidirectional screw, and one side of the limiting plate is attached to one side of the wire fixing plate.
[0013] Preferably, a connecting plate is threaded to one side of the bidirectional screw, and one side of the connecting plate is fixedly connected to one end of the guide rod.
[0014] The advantages of this utility model are:
[0015] This invention utilizes a wire-fixing mechanism. The connecting wire is confined within the wire placement groove via an inlet groove. The wire-fixing plate serves to secure the connecting wire. The wire-fixing plate is connected to a first support rod via a second support rod. The first support rod is rotatably connected to a ball seat via a ball head. This allows the wire-fixing plate to adapt to the changing force direction of the connecting wire when the connecting wire is pulled, through the interaction of the ball head and the ball seat. An extension plate and a first spring further define the position of the wire-fixing plate. On one hand, the first spring can reduce the pulling force when the connecting wire is accidentally pulled; on the other hand, the spring's resilience allows the displaced wire-fixing plate to return to its original position. This achieves a flexible fixation of the power cord connection, solving the problem that some power adapters with anti-bend functions can only simply fix the power cord connection to prevent it from swaying. However, when the power cord is accidentally pulled, the fixed connection has poor buffering effect, and large pulling forces can easily damage the power cord and the anti-bend structure, reducing its practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0024] This application discloses a power adapter with anti-bending function. (Refer to...) Figures 1 to 3 A power adapter with anti-bending function includes a power adapter body 1, a connecting wire 2 fixedly connected to one side of the power adapter body 1, and a wire fixing mechanism 3 provided on one side of the power adapter body 1.
[0025] The cable fixing mechanism 3 includes a ball seat 301, a ball head 302 rotatably connected to the inner cavity of the ball seat 301, a first support rod 303 fixed to the surface of the ball head 302, a second support rod 304 slidably connected to the inner cavity of the first support rod 303, a cable fixing plate 305 fixedly connected to one end of the second support rod 304, a cable inlet groove 306 and a cable placement groove 307 on one side of the cable fixing plate 305, the inner wall of the cable placement groove 307 communicating with the inner wall of the cable inlet groove 306, an extension plate 308 fixedly connected to one side of the cable fixing plate 305, a first spring 309 fixedly connected to one side of the extension plate 308, and one end of the first spring 309 fixedly connected to one side of the power adapter body 1. This power adapter with anti-bending function has the connecting wire 2 fixed to the power adapter body 1. The components are connected as one unit and connected to external equipment via connecting line 2. Connecting line 2 is confined in line slot 307 via inlet slot 306. Fixed plate 305 serves to fix connecting line 2. Fixed plate 305 is connected to first support rod 303 via second support rod 304. First support rod 303 is rotatably connected to ball seat 301 via ball head 302. When connecting line 2 is pulled, fixed plate 305 can adapt to the change of force direction of connecting line 2 through the cooperation of ball head 302 and ball seat 301. The position of fixed plate 305 is limited by extension plate 308 and first spring 309. On the one hand, first spring 309 can reduce the pulling force when connecting line 2 is accidentally pulled. On the other hand, the elasticity of first spring 309 can restore fixed plate 305 after displacement.
[0026] Reference Figure 2 and Figure 3 A positioning block 4 is slidably connected to the inner cavity of the second support rod 304. A second spring 5 is fixedly connected to one side of the positioning block 4. One end of the second spring 5 is fixedly connected to the inner wall of the second support rod 304. A positioning hole 6 is opened on the surface of the first support rod 303. The surface of the positioning block 4 is inserted into the inner wall of the positioning hole 6. Through the positioning block 4, the positioning block 4 is elastically connected to the inner cavity of the second support rod 304 by the second spring 5. The wire fixing plate 305 can slide along the inner wall of the first support rod 303 through the second support rod 304 to adjust the position of the fixed connecting line 2. When the position of the wire fixing plate 305 is adjusted to a suitable position, the positioning block 4 is inserted into the suitable positioning hole 6, and the second support rod 304 and the first support rod 303 are fixedly connected as one unit.
[0027] Reference Figure 3 and Figure 4The inner wall of the cable tray 307 is provided with a clamping plate 7, which is arc-shaped. The inner wall of the clamping plate 7 is in contact with the surface of the connecting wire 2. A guide rod 8 is fixedly connected to the surface of the clamping plate 7. A bidirectional screw 10 is rotatably connected to the inner cavity of the cable fixing plate 305. A limit plate 11 is fixedly connected to the surface of the bidirectional screw 10. One side of the limit plate 11 is in contact with one side of the cable fixing plate 305. An adjusting handle 12 is fixedly connected to one end of the bidirectional screw 10. A connecting plate 13 is threadedly connected to one side of the bidirectional screw 10. One side of the connecting plate 13 is fixedly connected to one end of the guide rod 8. The two arc-shaped clamps 7 can clamp and fix the surface of the connecting wire 2 through the clamp 7. The position of the clamp 7 is limited by the guide rod 8. The adjusting handle 12 can drive the bidirectional screw 10 to rotate. Since the bidirectional screw 10 is threadedly connected to the connecting plate 13, the bidirectional screw 10 rotates while driving the connecting plate 13. The connecting plate 13 drives the guide rod 8 and the clamp 7 to adjust the spacing, thereby adapting to connecting wires 2 of different sizes.
[0028] Reference Figure 4 A limiting sleeve 9 is fixedly connected to one side of the fixed plate 305. The surface of the guide rod 8 is slidably connected to the inner wall of the limiting sleeve 9. The limiting sleeve 9 and the fixed plate 305 are connected through the limiting sleeve 9. Therefore, the guide rod 8 can slide along the inner wall of the fixed plate 305 and the limiting sleeve 9. The limiting sleeve 9 can increase the restriction on the guide rod 8 and improve stability.
[0029] Working principle: The connecting cable 2 is fixedly connected to the power adapter body 1 as one unit. It connects to external devices through the connecting cable 2. The connecting cable 2 is confined in the cable placement groove 307 through the cable inlet groove 306. The cable fixing plate 305 serves to fix the connecting cable 2. The adjusting handle 12 can drive the bidirectional screw 10 to rotate. Since the bidirectional screw 10 is threadedly connected to the connecting plate 13, the rotation of the bidirectional screw 10 drives the connecting plate 13. The connecting plate 13 drives the guide rod 8 and the clamping plate 7 to adjust the spacing to accommodate connecting cables 2 of different sizes. The cable fixing plate 305 can slide along the inner wall of the first support rod 303 through the second support rod 304 to adjust the position of the fixed connecting cable 2. When the position of the cable fixing plate 305 is adjusted to a suitable position... When in place, the positioning block 4 is inserted into the appropriate positioning hole 6, fixing the second support rod 304 and the first support rod 303 into a whole. The wire fixing plate 305 is connected to the first support rod 303 through the second support rod 304. The first support rod 303 is rotatably connected to the ball seat 301 through the ball head 302, so that when the connecting line 2 is pulled, the wire fixing plate 305 can adapt to the change of the force direction of the connecting line 2 through the cooperation of the ball head 302 and the ball seat 301. The position of the wire fixing plate 305 is limited by the extension plate 308 and the first spring 309. On the one hand, the first spring 309 can reduce the pulling force when the connecting line 2 is accidentally pulled. On the other hand, the elasticity of the first spring 309 can restore the wire fixing plate 305 after displacement.
