Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1, a limit connection structure of an electrical appliance casing includes a first panel 21, a second panel 22, a male buckle and a female buckle. The male buckle is manufactured on the first panel, the female buckle is manufactured on the second panel, the first panel and the second panel are vertically arranged, and the first panel and the second panel are locked through the plug-in fit of the male buckle and the female buckle.

The male buckle comprises a male buckle body 1, wherein the male buckle body is connected with a first panel, one end (right side of the male buckle body in fig. 5) of the male buckle body axially extends to form a male buckle insertion plate 2, and one side (side facing the first panel, upper side of the male buckle insertion plate in fig. 5) of the male buckle insertion plate is provided with a limiting convex edge 3 and a guiding oblique edge 4.

The utility model discloses a buckle, including first panel, buckle body, buckle turn-ups and buckle turn-ups are equipped with the buckle turn-ups 5 on the first panel, buckle turn-ups are obtained through the panel beating to the border of buckle turn-ups, buckle turn-ups and buckle are arranged perpendicularly through the panel beating.

The female buckle comprises a female buckle wide groove 6, a female buckle transition groove 7 and a female buckle narrow groove 8 which are communicated in sequence; the width of the box transition groove gradually decreases from the box wide groove side to the box narrow groove side, and the length of the box wide groove is longer than the length of the pin (length in the horizontal direction in fig. 5). The second panel is provided with a female buckle flanging 9, the edge of the second panel is bent through a metal plate to obtain a female buckle flanging, and the female buckle is arranged on the female buckle flanging. The male buckle flanging is parallel to the female buckle flanging, and the male buckle is perpendicular to the female buckle flanging.

The pin thread plugboard and the guiding bevel edge play a guiding function, and the guiding bevel edge is used for guiding the limiting convex edge to slide into the box narrow groove, so that the pin thread can be automatically righted when being installed, and the pin thread can be ensured to slide into the box narrow groove smoothly from the box wide groove. Within a certain length range, the longer the length of the female buckle narrow groove is, the more reliable the limit function is.
