Detailed Description

The present utility model will be described in detail below with reference to the drawings and the specific embodiments, and in the present specification, the dimensional proportion of the drawings does not represent the actual dimensional proportion, but only represents the relative positional relationship and connection relationship between the components, and the components with the same names or the same reference numerals represent similar or identical structures, and are limited to the schematic purposes.

The top cover plate 1 of the present utility model is constructed as shown in fig. 1, in which the direction marks are indicated according to the usual state of the mounting of the storage plate 11 on the dishwasher. The top cover plate 1 comprises a storage plate 11, and the upper surface of the storage plate 11 is basically flat so as to allow a user to stably place articles for daily use. In the actual manufacturing production of the top cover plate 1, the object placing plate 11 may not be formed at one time, and the object placing plate 11 may be a separate part manufactured by a separate process and mounted on the top cover plate 1 to form a flat top surface, such as glass or other materials, mainly for the purposes of reducing injection molding defects and providing a product look and feel. The flange 12 is formed downward along the entire peripheral edge of the storage plate 11, the flange 12 is preferably formed continuously over the entire periphery, the bending resistance and the warping resistance of the flange 12 are enhanced by the flange 12 to enhance the capability of supporting the article, and the inner surface of the flange 12 is preferably provided with reinforcing ribs.

At least one plug-in connection 13 is arranged on the flange 12 located behind the storage plate 11. At least one hanging buckle 15 is arranged on the flange 12 in front of the object placing plate 11, and at least one buckle 14 is respectively arranged on the flanges 12 on the left side and the right side of the object placing plate 11.

The plug 13 is shown schematically in fig. 2. The plug-in component 13 is arranged on the inner side of the flanging 12, which is equivalent to reserving a space for mounting the object placing plate 11, so that the rear edge of the object placing plate 11 can be tightly attached to the rear surface of the machine body, the assembly break difference is reduced, and the rear of the machine body is ensured to be smooth. The plug 13 includes a slot 131 into which the corresponding connector is inserted and fitted. The two slots 131 are oppositely arranged, and when the connecting piece slides into the slot 131 from the inlet of the slot 131, the two slots 131 limit the connecting piece on the object placing plate 11 to realize detachable fixation. At least one groove 132 for positioning the connector is provided at the entrance of the slot 131, and the groove 132 has a horn shape with an opening larger than the inside thereof, such as the groove 132 of the V-shaped opening shown in fig. 2 of the present roof panel. When the connecting piece enters the slot 131, the positioning protrusions on the connecting piece enter the inside of the groove 132 from the wider opening of the groove 132, and the gradually narrowed groove 132 guides and positions the positioning protrusions on the connecting piece at the narrower inside, so that the positioning of the connecting piece in the left-right direction is realized. A clamping hole 133 is further formed at the entrance of the slot 131, and when the connecting piece goes deep into the slot 131 to a certain depth, the corresponding boss on the connecting piece is extruded into the clamping hole 133 to realize fastening and fixing of the slot 131. In the process that the card hole 133 is extruded into the slot 131, the position of the slot 131 where the card hole 133 is formed is elastically deformed and expanded outwards, so that the height of the groove 132 and the card hole 133 in the direction away from the inlet of the slot 131 is preferably kept substantially the same, and the card hole 133 is more easily elastically deformed due to the existence of the groove 132, so that the buckling process is smoother.

When the plug-in element 13 is arranged on the inner side of the flange 12, the plug-in element 13 preferably protrudes downwards beyond the edge of the flange 12, which is to fit the connecting element to a suitable height, ensuring that the clearance between the storage plate 11 and the rest of the machine body is consistent. And on the other hand, the space in the space surrounded by the flange 12 can be avoided. Since the inner plate 19 is also optionally mounted on the inner side of the storage plate 11, if the plug 13 is arranged completely on the inner surface of the flange 12, it is clear that interference with the inner plate 19 occurs when the inner plate 19 is mounted on the inner side of the storage plate 11, so that such a counter-measure is necessary. On the basis of this, in order to ensure the mounting strength of the downward-extending mounting plug 13, a reinforcing rib 134 for connecting the end faces of the plug 13 is also provided on the inner surface of the flange 12, and a plurality of reinforcing ribs 134 may be arranged in parallel at intervals and connected to the end faces of the plug 13. The stiffener 134 preferably has a gradually decreasing cross section extending from the end face of the plug 13 toward the storage plate 11, i.e., the stiffener 134 decreases in cross section in the downward-upward direction, also to avoid interference with the stiffener 134 during installation of the inner plate 19, in order to avoid the inner plate 19.

The catch 14 is shown schematically in fig. 3. For reasons similar to those of the plug-in connection 13, a snap-in 14 is likewise provided on the inside of the flange 12 for snap-engagement with other connectors or housings inside the machine body. The catch 14 is preferably arranged inside the flange 12 and grows downwards in a flush position with the lower edge of the flange 12. The clamping groove 141 is formed along the lower edge of the flanging 12, gaps among the clamping groove 141 are widest at the opening, the middle is narrowed, and the clamping groove 141 is slightly wider than the middle at the bottom. As shown in fig. 4, in the mounting and fastening, the top cover plate 1 is inserted into the slot hole a141 of the support plate a14 in the back-and-forth direction, and the support plate a14 is clamped in the slot hole a141 to form the fastening in the up-and-down direction. According to the installation mode shown in fig. 4, in the preferred design, the upper side edge of the clamping groove 141 is planar as shown in fig. 3 and is equal to the edge of the flanging 12, so that the installation gap between the support plate A14 and the flanging 12 after the clamping is ensured, and the beautiful appearance and dust prevention of the equipment shell are ensured. Accordingly, since the clip 14 is mounted on the lower edge of the flange 12, the clip 14 is preferably reinforced and fixed by the reinforcing ribs 134.

The structure of the hanging buckle 15 is shown schematically in fig. 5. The hanging buckle 15 is arranged at the front part of the inner surface of the object placing plate 11, and can be arranged on the inner surface of the flanging 12 at the front part of the object placing plate 11 or can be independently arranged.

The mounting surface 153 is preferably parallel to the storage plate 11, which results in the hanging clasp 15 being disposed generally perpendicular to the storage plate 11 downwardly. The head 155 has a larger cross section than the necked-down portion 154 so that the necked-down portion 154 may be used to effect a limit stop upon installation. Fig. 6 is a schematic installation diagram of the hanging buckle 15, where the hanging buckle 15 is used for fixing with the second supporting plate a151, and the second supporting plate 151 is correspondingly provided with a second slot a152, where the second slot a152 has a hole shape with a rear width larger than a front width, which means that the head 155 can pass through a position with a larger rear width of the second slot a152 but can be blocked by a position with a smaller front width of the second slot a 152. After the head 155 passes through the second slot A152, the second support plate A151 is moved backwards relatively, and the necking part 154 enters the front position of the second slot A152 to realize limit clamping.

The utility model also provides a plug-in connector for the mating assembly with the plug-in connector 13 of the storage plate 11.
