Abstract

<P>PROBLEM TO BE SOLVED: To provide a housing top-cover attachment and detachment device having a structure capable of easily detaching a top cover by respectively applying forces to elastic pieces of the top cover. <P>SOLUTION: Two piercing holes are vertically pierced in the top cover, and two elastic pieces 3 are mounted corresponding respectively to the piercing holes on the rear face of the top cover. In detaching the top cover, the user directly presses the pressing part of the two elastic pieces downward from the upper side of the top cover. Since respective fixing edges 31 of the two elastic pieces are fixed to the top cover, engaging edges 32 of the top cover are removed from corresponding engaging structures of the housing main body by simply applying forces to the respective two elastic pieces to simply detach the top cover. Besides, since a slope is formed in each of the engaging structures of the housing main body, the engaging edges of the elastic pieces slide to automatically position smoothly in the respective engaging structures by applying small forces to the respective elastic pieces by the user to easily attach the top cover to the housing main body. <P>COPYRIGHT: (C)2005,JPO&NCIPI

The left plate 23 and the right plate 24 are closed on the left side plate 11 and the right side plate 12 of the case 1.

  Please refer to FIGS. FIG. 2 is a side view of the left side plate of FIG. 3 is a side view of the right side plate of FIG. The engaging structures 13 and 14 of the left side plate 11 and the right side plate 12 of the case 1 are respectively formed as engaging concave grooves, and sliding portions 131 and 141 and engaging portions 132 and 142 are formed in the engaging grooves 131, respectively. , 141 and the engaging portions 132, 142 are formed with stopper portions 133, 143, and oblique end portions 134, 144 are obliquely inclined toward the rear side from the front side of the case 1 at the lower end portions of the stopper portions 133, 143. Is formed.

  Please refer to the perspective view from another view angle of the upper lid of the present invention in FIG. 4 together with FIG. The upper lid 2 is separately provided with two through holes 21 and 22 penetrating vertically. The two through holes 21 and 22 are located near the left side plate 11 and the right side plate 12 of the case 1.

  In addition, the elastic piece 3 is assembled to a portion corresponding to the two through holes 21 and 22 of the upper lid 2, and a fixed end 31 and an engagement end 32 are formed at two ends of each elastic piece 3. Among them, the fixed end 31 is fixed to the inside of the upper lid 2 away from the left side plate 11 and the right side plate 12 of the case 1, the engagement end 32 is an engagement convex edge, and in the engagement structures 13 and 14 of the case 1. Engaged. Note that the two elastic pieces 3 in this part are of a shared design. That is, the two elastic pieces 3 have the same structure and can be used by exchanging positions with each other. This is very convenient in manufacturing and can save cost, and can be simplified in the process of assembling with the upper lid 2.

  Please refer to FIG. 1, 2, 3, 4 and the operation display diagram of the assembly of the top cover of the present invention in FIG. The two elastic pieces 3 are formed with a pressing portion 33, which is located on one side close to the engaging end 32 between the fixed end 31 and the engaging end 32, and the pressing portion 33 has the through hole 21 of the upper lid 2, 22 is exposed upward.

  When the upper lid 2 is assembled to the case 1, the upper lid 2 is placed on the case 1, and the engaging end 32 of the elastic piece 3 of the upper lid 2 corresponds to the sliding portions 131, 141 of the engaging structures 13, 14 of the case 1. Then, the upper lid 2 is slid toward the front side of the case 1 by applying light force. At this time, the engagement end 32 of the elastic piece 3 is guided by the oblique ends 134 and 144 of the engagement structures 13 and 14 and is bent downward with the fixed end 31 as a fulcrum. It smoothly slides into the engaging portions 132 and 142 of the engaging structures 13 and 14, and further engages with the stopper portions 133 and 143 of the engaging structures 13 and 14, and thus the upper lid 2 and the case 1 are automatically positioned. Assembly is complete.

  Positioning slide grooves 112 and 122 can be formed on the left side plate 11 and the right side plate 12 of the case 1, and positioning convex columns 231 and 241 can be separately formed on the left plate 23 and the right plate 24 of the upper lid 2.
