[0005] The purpose of the utility model is to provide a power cord fixing device that is easy to process and quick to assemble, in order to address the defects and shortcomings of the prior art.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The present utility model provides a power cord fixing device, including a power cord and an electrical appliance housing, wherein the electrical appliance housing is provided with a wiring hole for the power cord to pass through, a positioning sleeve is provided on the outer fixing sleeve of the power cord, and a barb-shaped anti-pullout structure is formed on the first end of the positioning sleeve. Specifically, the barb-shaped anti-pullout structure can be various barb structures that can achieve an anti-detachment function, and a limiting structure is formed on the second end of the positioning sleeve. During assembly, the barb-shaped anti-pullout structure is squeezed through the wiring hole, the barb-shaped anti-pullout structure is placed inside the electrical appliance housing, and the limiting structure is placed outside the electrical appliance housing. Through the above-mentioned structural setting, the positioning sleeve is confined within the wiring hole, and because the power cord is fixed to the positioning sleeve, it can effectively prevent the power cord from detaching from the electrical appliance housing in the forward or reverse direction. In addition, the present utility model has a simple structure. During assembly, it is only necessary to squeeze the barb-shaped anti-pullout structure through the wiring hole, and assembly is quick and simple.

[0008] According to the above solution, a guide rib is fixedly mounted on the first end of the positioning sleeve, and a guide groove is provided within the wiring hole, through which the guide rib enters the interior of the appliance housing. This structural arrangement allows for assembly by first aligning the guide rib with the guide groove, and then squeezing the barbed anti-extraction structure through the wiring hole, effectively increasing assembly speed.

[0009] According to the above solution, a limiting groove is provided on the inner side of the appliance housing to restrict the circumferential movement of the guide rib. With this structural arrangement, during assembly, after the guide rib enters the appliance housing, the positioning sleeve is rotated, causing the guide rib to enter the limiting groove. One end of the guide rib is trapped within the limiting groove, preventing the power cord from rotating. It also forms a double undercut structure with the barbed anti-extraction structure, preventing the power cord from being pulled out in the opposite direction if the barbed anti-extraction structure fails.

[0010] According to the above scheme, a raised structure is provided on the inner side of the electrical housing around the wiring hole, the raised structure is provided with the limiting groove, a guide surface is provided between the guide groove and the raised structure, and the guide rib slides along the guide surface into the limiting groove. Specifically, the guide surface can be a slope or an arc-shaped surface, as long as it can assist the guide rib to detach from the guide groove and smoothly enter the limiting groove.

[0011] According to the above solution, the end of the guide rib that contacts the guide surface is provided with an inclined surface or an arcuate surface. Through the above structural arrangement, the guide rib can smoothly enter the limiting groove, further improving the assembly speed.

[0012] According to the above solution, the barbed anti-pullout structure includes a plurality of inclined blocks, which are arranged around the positioning sleeve and fixed to the first end of the positioning sleeve. Through the above structural arrangement, the barbed anti-pullout structure is simple in overall structure and easy to process.

[0013] According to the above solution, the barbed anti-pullout structure includes two oblique blocks, and the two oblique blocks are symmetrically distributed on both sides of the positioning sleeve. The first end of each oblique block is fixedly connected to the first end of the positioning sleeve, and the second end of each oblique block is located away from the positioning sleeve. The distance between the second ends of the two oblique blocks is greater than the diameter of the wiring hole. With this structural arrangement, when the two oblique blocks are squeezed, the large-diameter end of each oblique block will move toward the positioning sleeve, thereby reducing the distance between the oblique blocks and allowing the oblique blocks to completely pass through the wiring hole.

[0014] According to the above solution, the wiring hole is circular or rectangular, the outer surface of the inclined block is an arc surface, and the two inclined blocks are combined to form a cone shape. This structural arrangement facilitates the extrusion of the barbed anti-extraction structure into the interior of the electrical appliance housing, further improving assembly speed. It should be noted that the barbed anti-extraction structure formed by combining multiple inclined blocks into a cone shape can be extruded into a circular wiring hole, while two symmetrically arranged inclined blocks can be extruded into a rectangular wiring hole.

[0015] According to the above solution, the limiting structure is a limiting ring, the inner ring of which is fixed to the positioning sleeve, and the outer ring diameter of which is larger than the diameter of the wiring hole. Through the above structure, the positioning sleeve can be effectively restricted from moving into the electrical housing.

[0016] According to the above solution, the positioning sleeve, the barbed anti-pullout structure and the limiting structure are integrally formed. The above structural arrangement facilitates the processing of the present invention.

[0017] Beneficial effects of the utility model:

[0018] During assembly of the present invention, it is only necessary to squeeze the barbed anti-extraction structure through the wiring hole, so that the barbed anti-extraction structure is placed inside the appliance housing and the limiting structure is placed outside the appliance housing. This makes assembly quick and simple, and saves labor. In addition, the positioning sleeve is confined within the wiring hole, and the power cord is fixed to the positioning sleeve, which can effectively prevent the power cord from escaping from the appliance housing in either the forward or reverse direction.

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides a power cord fixing device, including a power cord 1 and an electrical appliance housing 2. In this embodiment, the electrical appliance housing 2 is an electric kettle base housing. The electrical appliance housing 2 is provided with a wiring hole 21 for the power cord 1 to pass through. The power cord 1 is fixed with a positioning sleeve 3, that is, the power cord 1 is arranged to pass through the positioning sleeve 3. The first end of the positioning sleeve 3 is formed with a barbed anti-extraction structure, and the second end of the positioning sleeve 3 is formed with a limiting structure. The positioning sleeve 3, the barbed anti-extraction structure and the limiting structure are integrally formed. During assembly, the barbed anti-extraction structure is squeezed through the wiring hole 21. The barbed anti-extraction structure is placed inside the electrical appliance housing 2, and the limiting structure is placed outside the electrical appliance housing 2. Through the above-mentioned structural arrangement, the positioning sleeve 3 is confined within the wiring hole 21. Because the power cord 1 is fixed to the positioning sleeve 3, it can effectively prevent the power cord 1 from detaching from the electrical appliance housing 2 in either forward or reverse direction. During assembly, it is only necessary to squeeze the barbed anti-extraction structure through the wiring hole 21, making assembly quick and simple.

[0028] Furthermore, a guide rib 4 is fixedly provided on the first end of the positioning sleeve 3, and a guide groove 5 is provided within the wiring hole 21. The guide rib 4 enters the interior of the electrical housing 2 through the guide groove 5. With this structural arrangement, during assembly, the guide rib 4 is first aligned with the guide groove 5, and then the barbed anti-pullout structure is squeezed through the wiring hole 21, which can effectively increase assembly speed. In this embodiment, the guide rib 4 is preferably a rectangular block fixed to the positioning sleeve 3, corresponding to the structure of the guide rib 4, and the guide groove 5 is configured as a rectangular groove.

[0029] Further, if Figure 4 As shown, the inner side of the electrical housing 2 is provided with a limiting groove 6 for limiting the circumferential movement of the guide rib 4, and the inner side of the electrical housing 2 is provided with a protruding structure 7 around the wiring hole 21, and the protruding structure 7 is provided with the limiting groove 6, and a guide surface 8 is provided between the guide groove 5 and the protruding structure 7, and the guide rib 4 slides into the limiting groove 6 along the guide surface 8, and the guide surface 8 is an inclined surface. Through the above-mentioned structural arrangement, during assembly, after the guide rib 4 enters the interior of the electrical housing 2, the positioning sleeve 3 is rotated, in the direction of rotation indicated by the arrow in the figure, so that the guide rib 4 can transition to the limiting groove 6 along the guide surface 8, and one end of the guide rib 4 is confined in the limiting groove 6, which can prevent the power cord 1 from rotating, and can also form a double inverted buckle structure with the barbed anti-pullout structure, which can prevent the power cord 1 from being pulled out in the reverse direction when the barbed anti-pullout structure fails.

[0030] Furthermore, an inclined surface is provided on one end of the guide rib 4 that contacts the guide surface 8. Through the above-mentioned structural arrangement, the guide rib 4 can smoothly enter the limiting groove 6, further improving the assembly speed.

[0031] Further, if Figure 1-2 As shown, the barbed anti-pullout structure includes two bevel blocks 9, which are symmetrically distributed on both sides of the positioning sleeve 3. The first end of the bevel block 9 is fixedly connected to the first end of the positioning sleeve 3, and the second end of the bevel block 9 is set away from the positioning sleeve 3. The distance between the second ends of the two bevel blocks is larger than the diameter of the wiring hole. With the above-mentioned structural setting, when the two bevel blocks 9 are squeezed, the second ends of the bevel blocks 9 move toward the positioning sleeve 3, thereby reducing the distance between the bevel blocks 9, allowing the bevel blocks 9 to completely pass through the wiring hole 21.

[0032] Furthermore, the wiring hole 21 is circular, the outer side of the inclined block 9 is an arc surface, and the two inclined blocks 9 are combined into a cone shape. Through the above-mentioned structural setting, it is convenient for the barbed anti-extraction structure to be squeezed into the interior of the electrical housing 2, further improving the assembly speed.

[0033] Furthermore, the limiting structure is a limiting ring 10, the inner ring of which is fixed to the positioning sleeve 3, and the outer ring diameter of which is larger than the diameter of the wiring hole 21. With the above-mentioned structural arrangement, the positioning sleeve 3 can be effectively restricted from moving into the interior of the electrical housing 2.

[0034] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
