The specific implementation mode is as follows:
in order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The utility model discloses a fixed knot of narrow frame electronic clock moulds shell constructs, including drain pan 1, face guard shell 2 and the display module 3 who establishes between drain pan and face guard shell, display module 3 is the information such as time, date that is used for showing the electronic clock, and it is current conventional technique, does not describe here reluctantly, and the characteristic of this application lies in following structure, has seted up display window 4 on the face guard shell 2, locate to form side frame 5 on the face guard shell 2 at display window 4 side, side frame 5 width is 4.5mm, side frame 5 is equipped with lug 6 towards the direction of drain pan, be equipped with catching groove 7 on lug 6, be equipped with the depressed groove 9 that makes this wall thickness thin on the perisporium 8 that corresponds with the lug at drain pan shell oral area, the tank bottom of depressed groove is equipped with the protruding wedge 10 of detaining the catching groove, during the use, when drain pan and face guard shell are pressed mutually, protruding wedge 10 promptly detains in catching groove 7, thereby realizing the relative fixation of the bottom shell and the mask shell.
For firm connection, the position of the convex sheet is located at the position where the upper edge and the lower edge of the rectangular display window extend, the corresponding position of the bottom shell is also provided with the concave groove 9, the convex sheet 6 or the concave groove 9 is arranged at the corresponding position, so that good connection firmness can be realized, and through tests, under the condition that all parts are the same in size, the effect that the convex sheet 6 or the concave groove 9 is arranged at other positions of the side frame and is not arranged at the positions is good; of course, in order to increase the connection reliability, the protruding pieces 6 or the recessed grooves 9 configured as described above are also provided on the upper and lower edge portions of the bottom case 1 and the mask case 2.
Furthermore, in order to facilitate the clamping, the lug is in a rectangular shape, the free end of the lug is provided with a wedge surface 11, and one side of the lug 6 opposite to the side where the convex wedge block is buckled into the buckling groove is provided with a plurality of reinforcing ribs 12; the concave groove is in a cone hopper shape with a large opening end and a small groove bottom, and the wall thickness of the peripheral wall of the opening part of the bottom shell is the same.
Further, in order to realize the inclined support of the electronic clock, the lower portion of the back of the bottom shell is hinged with a supporting plate 13, the upper portion of the supporting plate is hinged in a hinge hole 15 of the bottom shell through a hinge pin 14 arranged on the lateral portion of the supporting plate, a support lug 16 is arranged on the supporting plate and close to the hinge pin, a convex block 17 is arranged on the side face of the support lug, and a through groove 18 for the support lug and the convex block to be clamped in is formed in the bottom shell.
Furthermore, in order to achieve good effects in the inclined supporting and folding states, the bottom shell is provided with two through grooves 18 which are symmetrically arranged, the supporting plate is correspondingly provided with two support lugs and lugs, the width of each through groove is slightly larger than the total thickness of the support lugs and the lugs, the distance between two end faces, which are relatively far away, of the two lugs is larger than the distance between two side faces, which are relatively far away, of the two through grooves,
when the bottom shell 1 and the supporting plate 13 are in a forked state, the bottom shell 1 and the supporting plate 13 need to be folded, the convex block 17 can be resisted by two side faces, which are relatively far away from the through groove, so that the supporting plate 13 can not be folded with the bottom shell 1 easily when the electronic clock is obliquely erected, the stability of oblique erection is influenced, the convex block 17 can be clamped over the through groove 18 only by folding the supporting plate 13 and the bottom shell 1 with certain pressure, similarly, when the supporting plate 13 is turned over to form oblique support, the convex block 17 can get rid of the limitation of the side face of the through groove 18 only by certain pulling force, the looseness and the collapse of the supporting plate 13 and the bottom shell 1 when the supporting plate 13 is folded are avoided, the functions can be realized because the bottom shell 1, the supporting plate 13 and the support lugs 16 are made of plastic products, the plastic products have certain plasticity, and the support lugs 16 slightly swing inwards in the process of the folding or the branching of the bottom shell 1, the lugs 16 and the projections 17 can pass through the through slots 18 smoothly.
Because the lock joint of this product design is relatively not dismantled well, consequently need consider to make things convenient for getting of battery to adorn, be equipped with notch 19 on the lateral part of above-mentioned drain pan, the corresponding drain pan internal surface of notch 19 is equipped with bounding wall 20, sliding connection has the groove box body 21 that is used for splendid attire button cell 22 in the bounding wall, groove box body side is equipped with elastic lug 23, convex point 24 has on the elastic lug, the position that corresponds with convex point on the bounding wall is equipped with recess 25, puts button cell 22 into groove box body 21 after, in pushing into bounding wall 20 through notch 19, in pushing to the end because convex point 24 blocks into recess 25 promptly, has prevented that groove box body 21 from deviating from at will promptly, and needs certain pulling force when needing to take out groove box body 21, makes convex point 24 overcome elasticity and breaks away from recess 25.
The utility model discloses narrow side frame electronic clock moulds shell fixed knot and constructs can make face guard shell and drain pan accomplish narrow to 4.5mm in the side frame, need not to connect firmly under the screw locking condition, and the appearance that has not only increased the electronic clock product is pleasing to the eye, need not to lock the screw moreover, as long as press the knot can connect firmly, has improved the packaging efficiency greatly.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
