Generally speaking, whether it is one-piece or detachable, electrical appliances usually have a foot pad structure at the bottom to support the electrical appliance itself. Taking common microwave oven products as an example, there are currently two main ways to fix the oven feet of microwave ovens: screw fixing and buckle fixing. The use of screws to fix the screws is prone to slipping, causing the feet to loosen, and the screws will rust over time, affecting the use and inconvenient operation and affecting efficiency. The other type of buckle fixing method may cause the buckle to break or not tighten during the installation process (due to structural limitations, the design leaves a gap). Consumers feel loose when touching it, and shake the whole machine to collide with the contacting parts to produce abnormal noise, leading to dissatisfaction or complaints. The above two methods are inconvenient to disassemble, and the effect of re-use is worse. Therefore, it is necessary to improve and optimize the existing detachable electrical foot pad structure to improve the user experience of the corresponding electrical products. Utility Model Content

[0022] Example:
[0023] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0025] As attached Figure 1-5 The plastic foot pad installation and fixing structure shown includes a mounting base plate 1 and an elastic snap-on plastic foot pad 2, wherein the mounting base plate 1 is provided with a foot pad installation hole 3, wherein the elastic snap-on plastic foot pad 2 is detachably mounted in the foot pad installation hole 3, wherein the foot pad installation hole 3 includes a flange hole 301, wherein the elastic snap-on plastic foot pad 2 includes a foot pad base 201 and an elastic snap-on portion, wherein the elastic snap-on portion includes an installation guide end 202 and a serrated snap-on segment 203, and cooperates with the flange hole 301 to form a detachable elastic snap-on structure. The plastic foot pad installation and fixing structure of the present embodiment is a bottom support structure suitable for household electrical appliances, and a new type of detachable electrical appliance foot pad installation structure is formed by improving and optimizing the plastic foot pad structure of electrical appliances, and a plastic foot pad with an elastic snap-on is used for fixing and installation. During installation, align the elastic snap-on plastic foot pad 2 with the foot pad mounting hole 3 and push it in from the outside to the inside so that the serrated clamping section 203 and the flanged hole 301 on the mounting base plate 1 form a lock fit, and fix the elastic snap-on plastic foot pad 2 in the foot pad mounting hole 3; when it is necessary to disassemble, pinch the serrated clamping section 203 to shrink and deform inward, and withdraw the elastic snap-on plastic foot pad 2 from the foot pad mounting hole 3 to the outside, which is convenient for disassembly and assembly, does not damage the foot pad after disassembly, can be used again without affecting the effect of use. When the plastic foot pad installation and fixing structure of this embodiment is applied to corresponding electrical products (such as microwave ovens, electric ovens, etc.), due to the cooperation of the serrated clamping section 203 and the flanged hole 301, the elastic snap-on plastic foot pad 2 is clamped more firmly, avoiding the occurrence of gaps to cause loose shaking up and down, which produces sound by colliding with each other, and can rotate in the left and right directions, thereby improving the overall user experience of the electrical products to which it is applied.
[0026] As a feasible implementation method, see the attached Figure 5As shown, in this embodiment, the cross-section of the foot pad base 201 is T-shaped, and the elastic snap portion extends to both sides at the upper end of the foot pad base 201 to form snap flaps, and the upper ends of the snap flaps are connected to the upper part of the foot pad base 201 through the installation guide end 202, and the lower ends of the snap flaps are suspended. In combination with the elastic snap plastic foot pad 2 of this embodiment, which is made of plastic material, the snap flaps have a certain deformation ability relative to the foot pad base 201. During the installation process, the inner periphery of the flange hole 301 compresses the snap flaps to shrink and deform inward, so that they can pass through the flange hole 301. When the snap flaps are completely passed through, they are no longer restricted by the flange hole 301 and return to their original shape outward, and then are clamped on the upper edge of the flange hole 301 to achieve the installation and fixing effect of preventing the elastic snap plastic foot pad 2 from falling out.
[0027] In this embodiment, the buckle petals are arc-shaped from top to bottom, and the outer distance width between the two buckle petals is greater than the diameter of the flange hole 301. Figure 5 As shown, the arc-shaped snap-on flap structure makes the elastic snap-on portion form a structure that is small at the top and large at the bottom. Cooperating with the installation guide end 202 at its front end, the elastic snap-on plastic foot pad 2 is easier to be inserted into the foot pad installation hole 3 on the installation base plate 1; after the snap-on flap is inserted into place and returns to its original shape, since the outer distance width between the two snap-on flaps is greater than the diameter of the flange hole 301, the elastic snap-on plastic foot pad 2 cannot fall out of the foot pad installation hole 3, which not only facilitates the insertion operation of the elastic snap-on plastic foot pad 2, but also ensures the installation and fixing effect of the elastic snap-on plastic foot pad 2.
[0028] Preferably, in this embodiment, a reinforcing rib 204 connected to the foot pad base 201 is provided on the inner side of the buckle flap. Figure 3 and attached Figure 5As shown, the reinforcing ribs 204 of this embodiment are obliquely arranged reinforcing ribs 204. During the insertion and removal process of the elastic snap-on plastic foot pad 2, the force applied to the snap-on petals and their reinforcing ribs 204 is an inward force in a substantially horizontal direction. Since the reinforcing ribs 204 of this embodiment are obliquely arranged, it is easier for the snap-on petals to shrink and deform inward when subjected to the squeezing force in this direction, that is, it is easy to achieve the insertion and removal of the elastic snap-on plastic foot pad 2. During the normal use of the elastic snap-on plastic foot pad 2, the reinforcing ribs 204 can prop open the serrated clamping section 203, effectively maintaining the predetermined shape structure of the elastic snap-on plastic foot pad 2, and the snap-on petals are not easy to deform and easily fall out of the foot pad mounting hole 3, which plays a role in strengthening and preventing falling off, so that the elastic snap-on plastic foot pad 2 can be firmly installed on the mounting base plate 1, ensuring the actual use effect of the plastic foot pad mounting and fixing structure of this embodiment. It is easy to understand that the reinforcing ribs 204 of this embodiment can be arranged to be inclined from top to bottom as shown in the accompanying drawings, or can be arranged to be inclined from bottom to top, and the same technical effect can be achieved.
[0029] In this embodiment, the outer periphery of the foot pad mounting hole 3 is provided with a plurality of positioning bosses 4 for limiting the radial movement of the foot pad base 201. The positioning bosses 4 protrude from the lower side end surface of the mounting base plate 1 and roughly surround a groove cavity of a size that matches the foot pad base 201. After the elastic snap-on plastic foot pad 2 is inserted, its foot pad base 201 is just located in the groove cavity, that is, the foot pad base 201 can cooperate with the positioning bosses 4 to play a positioning and limiting role, preventing it from moving in the radial direction, and avoiding the situation where the elastic snap-on plastic foot pad 2 shakes after installation and affects the use effect. On the other hand, the plurality of positioning bosses 4 arranged around the outer periphery of the foot pad base 201 also play a certain protective role for the foot pad base 201 on its inner side. Specifically, when the applied electrical product moves, if the bottom hits an obstacle such as a step, the positioning bosses 4 can play a protective role, and the obstacle is not easy to directly hit the foot pad base 201 and damage the plastic foot pad installation and fixing structure of this embodiment.
[0030] In this embodiment, the number of the positioning bosses 4 is 4, and they are evenly spaced along the circumference of the foot pad mounting hole 3. Specifically, as shown in the attached drawings, two groups of positioning bosses 4 are arranged opposite to each other along the intersecting cross lines, forming collision protection for the foot pad base 201 in the four directions of front, back, left, and right, which can basically meet the protection requirements. Of course, it should be noted that the position and number of the positioning bosses 4 shown in the attached drawings are not the only restrictions on the positioning bosses 4 of the utility model. In actual application, the number, position and setting method of the positioning bosses 4 can be increased, decreased and adjusted according to specific conditions and design requirements, as long as the positioning restriction and protection functions of the above-mentioned foot pad base 201 can be exerted.
[0031] In this embodiment, the thickness of the foot pad base 201 is greater than the height of the positioning boss 4, that is, after assembly, the foot pad base 201, which is the most protruding part of the bottom side of the plastic foot pad installation and fixing structure, contacts the supporting surface (generally a desktop or tabletop on which the electrical product is placed). The foot pad base 201 plays a supporting function, and other structures are used to achieve the positioning, limiting, quick installation and disassembly, and structural protection of the elastic snap-on plastic foot pad 2. In a preferred embodiment, anti-slip grooves 205 are provided on the outer surface of the foot pad base 201 to increase the friction between the foot pad base 201 and the supporting surface, so that the electrical product used can be better placed on the supporting surface for use and avoid easy sliding.
[0032] As described above, the plastic foot pad installation and fixing structure of the present invention is a bottom support structure suitable for household electrical appliances. The embodiment shown in the accompanying drawings illustrates the specific application of the plastic foot pad installation and fixing structure of the present invention in a microwave oven product. It is easy to understand that the plastic foot pad installation and fixing structure of the present invention is applied to other (such as electric ovens) cooking electrical appliances. It is sufficient to provide the plastic foot pad installation and fixing structure on these applied cooking electrical appliances. For example, a feasible application method is to provide the foot pad installation hole 3 on the bottom plate of the casing of the cooking appliance. The elastic snap-on plastic foot pad 2 of the present invention is a detachable independent component. When the foot pad installation hole 3 is provided on the corresponding cooking appliance, the elastic snap-on plastic foot pad 2 can be installed and used as the bottom support structure of the cooking appliance. The plastic foot pad installation and fixing structure of the present invention has wide applicability for household electrical appliances.
[0033] The above only describes the preferred embodiments of the utility model, which cannot be understood as limiting the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. In short, all changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
