Description

Technical Field

[0001] This utility model relates to wall-mounted water purifiers, and more particularly to a power cord fixing device for wall-mounted water purifiers. Background Technology

[0002] Wall-mounted water purifiers typically have their power cords run from the rear of the unit into the interior. In wall-mounted installations, the space for the power cord is severely limited due to the unit's proximity to the wall, and the cord must withstand greater mechanical loads (such as long-term hanging and wall pressure) compared to countertop water purifiers. Current technologies mostly use external clip-on power cord fixing structures. While these structures provide basic restraint, they often fail to provide sufficient constraint in the confined space of wall-mounted installations, easily leading to loosening or even detachment of the power cord. Furthermore, during installation, the power cord is prone to being squeezed or folded inside the machine due to uneven stress, potentially causing fatigue wear, poor electrical contact, and other problems over time, affecting the stability and safety of the equipment. Therefore, there is an urgent need to develop a power cord fixing device specifically designed for the unique operating conditions of wall-mounted water purifiers to improve constraint strength and optimize cable layout reliability. Utility Model Content

[0003] To achieve the above objectives, this utility model provides a wall-mounted water purifier power cord fixing device, characterized in that it includes: a cable passage groove and a pressure plate screw seat disposed on the inner side of the rear cover; the cable passage groove includes a lower groove seat and an upper groove cover that cooperate with each other; the length of the upper groove cover is less than that of the lower groove seat, so that the tail end of the cable passage groove forms an upper opening; a pressure plate, which is fixedly connected to the pressure plate screw seat by screws; the bottom of the pressure plate is provided with a hemispherical protrusion; when the pressure plate is installed on the pressure plate screw seat, the hemispherical protrusion presses the power cord tightly into the lower groove seat through the upper opening of the cable passage groove.

[0004] Furthermore, the upper opening length at the tail end of the cable tray is 10-20mm, and the remaining opening length after the pressure plate is installed is not less than 3mm.

[0005] Furthermore, the hemispherical protrusion is located at the bottom of the pressure plate and corresponds to the tail end of the upper groove cover. The distance between the hemispherical protrusion and the tail end of the upper groove cover is controlled by adjusting the tightness of the screw.

[0006] Furthermore, the wire channel and pressure plate screw seat are integrally formed structural components with the rear cover.

[0007] Furthermore, the pressure plate is provided with two threaded holes, and the axial direction of the threaded holes is perpendicular to the extension direction of the power line in the wire groove.

[0008] This device utilizes a combined design of a cable tray and a pressure plate structure to precisely confine the power cord within the shaped groove. The hemispherical protrusion at the bottom of the pressure plate applies progressive clamping force, significantly enhancing the cable's restraint strength and preventing displacement or wrinkling due to tension. Simultaneously, the tightening of the pressure plate screws can be adjusted to accommodate the distance between the protrusion and the end of the groove, flexibly adapting to the installation requirements of different wire diameters while balancing assembly efficiency and anti-loosening effects. Furthermore, the integrated molding process of the cable tray and rear cover simplifies structural complexity, reducing manufacturing costs while ensuring overall reliability. The limited design of the tail opening length and pressure plate installation allowance further balances cable fixation stability and maintenance convenience, effectively addressing potential issues such as power cord fatigue wear and poor contact during long-term use of wall-mounted water purifiers.

[0009] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0017] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0018] like Figure 1 As shown, the wall-mounted water purifier 1 equipped with the power cord fixing device according to this utility model can be hung on the wall as a whole by hooks 4, and its power cord 5 is inserted into the body through the power cord hole 3 at the bottom of the rear cover 2 of the wall-mounted water purifier 1.

[0019] like Figure 2-6 As shown, the power cord fixing device according to this utility model includes a cable guide groove 6 and a pressure plate screw seat 7 disposed inside the rear cover 2. Both the cable guide groove 6 and the pressure plate screw seat 7 are integrally injection molded with the rear cover 2. The cable guide groove 6 includes a lower groove seat 61 and an upper groove cover 62. The power cord 5 passes through the power cord hole 3 and then enters the machine through the cable guide groove 6. The upper groove cover 62 is shorter than the lower groove seat 61, so that the tail end of the cable guide groove 6 forms an upper opening. The pressure plate screw seat 7 is located above the cable guide groove 6. The pressure plate 8 is provided with two threaded holes 81 and a hemispherical protrusion 82 at the bottom. When the pressure plate 8 is installed on the pressure plate screw seat 7 with screws, the pressure plate 8 presses the power cord tightly against the lower groove seat 61 of the cable guide groove 6 through the upper opening of the cable guide groove 6. Furthermore, the tighter the screws on the pressure plate 8 are tightened, the closer the hemispherical protrusion 82 on the pressure plate 8 is to the tail end of the upper groove cover 62, and the tighter the power cord 5 will be fixed.

[0020] like Figure 7 As shown, in another embodiment, the power cord 5 can be folded upward through the opening above the tail end of the wire groove 6, and then the power cord 5 can be pressed tightly between the pressure plate 8 and the pressure plate screw seat 7.

[0021] In a preferred embodiment, the upper opening length at the tail end of the wire guide 6 is 10-20mm. After installing the pressure plate 8, the remaining upper opening length at the tail end of the wire guide 6 is not less than 3mm.

[0022] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and this invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
