DETAILED DESCRIPTION

[0022] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a power cord plug with a bending protection function, comprising a plug 1, a cable 2 is connected to the surface of the plug 1, and protective components 3 are arranged on both sides of the plug 1. The protective components 3 include: a protective cover 1 30, a protective cover 2 31, a rubber cover 32, a limiting hole 33, a slide groove 34, a slide plate 35, a through hole 36, a linkage plate 37, a spring 38, a block 39, a ramp 1 300, a ramp 2 301, a knob 302, a slot 303, a cavity 304, and a spiral spring 305.

[0023] The protective cover 1 30 is arranged above the plug 1, and the protective cover 2 31 is arranged below the plug 1. The surfaces of the protective cover 1 30 and the protective cover 2 31 are fixed with rubber covers 32. The surface of the protective cover 2 31 is provided with a limit hole 33, and the inner wall of the limit hole 33 is provided with a slide groove 34. The inner wall of the slide groove 34 is slidably connected with a slide plate 35. The inside of the slide plate 35 is provided with a through hole 36. The inner wall of the through hole 36 is attached with a linkage plate 37. The slide plate 35 and the linkage plate 37 are both provided with There are four groups, and the four groups of slide plates 35 and linkage plates 37 are arranged in a circular array with the center of the limiting hole 33 as the axis center. A spring 38 is fixed between the four groups of linkage plates 37. A clamping block 39 is fixed on the surface of the slide plate 35 on one side close to the center of the limiting hole 33. The side of the clamping block 39 close to the plug 1 is set as an inclined surface 1 300, and the side of the clamping block 39 away from the inclined surface 1 300 is set as an inclined surface 2 301. A cavity 304 is opened inside the protective cover 1 30, and the inner wall of the cavity 304 is fixed. The cam 304 is provided with a spiral spring 305, and a knob 302 is fixed at one end of the spiral spring 305 away from the cavity 304. The knob 302 passes through the protective cover 1 30, and the knob 302 is rotatably connected to the protective cover 1 30. A slot 303 is provided on the surface of the knob 302. The plug 1 is placed between the protective cover 1 30 and the protective cover 2 31 so that the bottom of the knob 302 enters the limiting hole 33. When the surface of the knob 302 contacts the inclined surface 1 300 of the block 39, the block 39 drives the slide plate 35 to move away from the side of the center of the limiting hole 33. The block 39 is parallel to the slot 303. Under the action of the spring 38, the block 39 enters the slot 303, thereby stabilizing the protective cover 1 30 and the protective cover 2 31, so that the protective cover 1 30 and the protective cover 2 31 wrap the plug 1 and the cable 2, thereby preventing the connection point between the plug 1 and the cable 2 from bending, which may cause power leakage, short circuit, electrical fire and other safety problems.

[0024] A limiting groove 4 is provided on the inner side of the protective cover 1 30 and the protective cover 2 31, and a limiting block 5 is fixed on the surface of the plug 1. When the protective cover 1 30 and the protective cover 2 31 are stable, the limiting block 5 will enter the limiting groove 4, so that the limiting block 5 limits the protective cover 1 30 and the protective cover 2 31 to avoid separation during long-term use. The cross-sections of the limiting block 5 and the limiting groove 4 are both right-angled triangles, which can limit the limiting block 5 to the limiting groove 4. The slide plate 35 and the linkage plate 37 are both arranged in an arc shape, and will not cause motion interference when moving. There are four groups of slide grooves 34, and the four groups of slide grooves 34 are all arranged in a circular array with the center of the limiting hole 33 as the axis, which can limit the moving direction of the slide plate 35. The cross-section of the rubber cover 32 is arranged in a semicircular shape, which can adapt to the cable 2.

[0025] When the plug 1 needs to be used, the personnel places the plug 1 between the protective cover 1 30 and the protective cover 2 31, and at the same time, the bottom of the knob 302 enters into the limiting hole 33. When the surface of the knob 302 contacts the inclined surface 1 300 of the block 39, the block 39 drives the slide plate 35 to move away from the side of the center of the limiting hole 33. At the same time, the radial synchronous movement of the four groups of slide plates 35 can be achieved through the provided slide groove 34 and the linkage plate 37. When the surface of the knob 302 contacts the inner wall of the limiting hole 33, the block 39 is parallel to the slot 303. At this time, under the action of the spring 38, the block 39 enters the slot 303, thereby stabilizing the protective cover 1 30 and the protective cover 2 31. , so that the protective cover 1 30 and the protective cover 2 31 wrap the plug 1 and the cable 2, avoiding bending of the connection point between the plug 1 and the cable 2, which may cause safety problems such as power leakage, short circuit and electrical fire. At the same time, when the protective cover 1 30 and the protective cover 2 31 are stable, the limit block 5 will enter the limit groove 4, so that the limit block 5 limits the protective cover 1 30 and the protective cover 2 31 to avoid separation during long-term use. When the protective cover 1 30 and the protective cover 2 31 need to be removed, the personnel can turn the knob 302, and the inner wall of the slot 303 will contact the inclined surface 2 301, so that the block 39 will be separated from the slot 303, so that the personnel can separate the protective cover 1 30, the protective cover 2 31 and the plug 1.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
