Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Fig. 1～5, the preferred embodiment providing for the utility model.

As depicted in figs. 1 and 2, the utility model embodiment proposes a kind of drain pan 100, comprise housing 1 and cover plate 2, housing 1 lower surface is provided with the recessed groove 11 of depression upward, the bottom land wall 111 of recessed groove 11 is provided with through hole 12, through hole 12 is through housing 1 upper surface, the hole wall of through hole 12 is provided with buckling parts 13, cover plate 2 upper surfaces are provided with buckle 21, buckle 21 stretches in through hole 12, active buckle is in buckling parts 13, and cover plate 2 upper surfaces are connected to the bottom land wall 111 of recessed groove 11, between cover plate 2 and the bottom land wall 111 of recessed groove 11, is provided with O-ring seal 3.

Cover plate 2 is seated in recessed groove 11, the bottom land wall 111 of recessed groove 11 stops cover plate 2 to enter in through hole 12, and buckle 21 on cover plate 2 can insert through hole 12, buckle 21 inserts the rear also positive dirction of through hole 12 and turns an angle, buckling parts 13 snappings on itself and housing 1, stoped cover plate 2 from the interior taking-up of recessed groove 11, cover plate 2 upper surfaces and bottom land wall 111 butts, and O-ring seal 3 is located between cover plate 2 and bottom land wall 111, housing 1 and the junction of cover plate 2 are sealed, stop water to enter in drain pan 100 by through hole 12.

Cover plate 2 counter-rotation certain angles, buckle 21 departs from buckling parts 13, and cover plate 2 is removed from recessed groove 11, and now, user sees through recessed groove 11 and through hole 12, changes the part of being located in drain pan 100.

As shown in Figure 3, buckling parts 13 comprises the raised line 131 extending internally from the hole wall of through hole 12, and raised line 131 is alternate to be arranged around through hole 12.Between adjacent raised line 131, there is gap, buckle 21 inserts gap, and after turning an angle, buckle 21 is blocked by raised line 131, stoped buckle 21 to move down, and when after buckle 21 counter-rotation certain angles, buckle 21 is got back to gap location, and now, buckle 21 is not blocked by raised line 131, can move out down in through hole 12, thereby buckle 21 is realized active buckle with buckling parts 13.Buckling parts 13 can also be the endless groove that comprises outside depression, the hole slot of through hole 12 is provided with connectivity slot, connectivity slot is communicated in respectively endless groove and recessed groove 11, buckle 21 enters endless groove by connectivity slot, buckle 21 rotates in endless groove, the groove sidewall of endless groove can block buckle 21, equally also can realize active buckle.

Certainly buckling parts 13 can also be other structure, and only need and buckle 21 are realized active buckle.

As shown in Figure 3, raised line 131 upper surfaces are provided with block 1310, and block 1310 one end extend to the end of raised line 131, and the other end and raised line 131 upper surfaces enclose draw-in groove 1311, and draw-in groove 1311 is through the head end of raised line 131.Buckle 21 inserts in gap, because having stopped buckle 21 positive dirctions, block rotates, buckle 21 can only counter-rotation, that is to say that buckle 21 can only rotate towards draw-in groove 1311 directions, buckle 21 rotates and enters after draw-in groove 1311, can be blocked it by block 1310 and be rotated further, avoid in the excessive gap of carrying out another place of rotational angle.

Raised line 131 can be one-body molded with block 1310.

Because raised line 131 is provided with block 1310, the sign that can be provided with out and close in housing 1 lower surface, opens and proceeds to position in draw-in groove 1311 and buckle 21 with buckle 21 respectively with the sign of closing to produce position outside draw-in groove 1311 corresponding, is convenient to user's operation.

As shown in Figure 4, cover plate 2 upper surfaces are provided with the step 22 towards projection, and step 22 inserts in through hole 12, and buckle 21 comprises the hook part 211 that the outside bending in support portion 210 and support portion 210 forms, support portion 210 is around step 22 edge placement, and hook part 211 stretches out in outside step 22 edges.Buckle 21 inserts behind gap, now, raised line 131 can not stop hook part 211, after rotate support portion 210, hook part 211 is positioned at raised line 131 tops, hook part 211 and raised line 131 butts, raised line 131 blocks hook part 211, restriction hook part 211 moves down, thereby limited cover plate 2, moves down, and cover plate 2 is fixed on housing 1.

As shown in Figure 2, the bottom land wall 111 of recessed groove 11 is provided with annular recess 112, and O-ring seal 3 is placed in groove 11, and with cover plate 2 upper surface butts.O-ring seal 3 is installed in annular recess 112, and its lower surface protrudes from annular recess 112, and O-ring seal 3 lower surfaces and cover plate 2 upper surface butts, realize the sealing between bottom land wall 111 and cover plate 2.

Annular recess 112 is for O-ring seal 3 is installed, and fixed seal ring 3, in its groove, avoids O-ring seal 3 move and affect sealing between bottom land wall 111 and cover plate 2 at bottom land wall 111.

As shown in Figure 1, cover plate 2 lower surfaces are provided with bar-shaped trough 23, and bar-shaped trough 23 is middle towards the curved layout of sunken inside.Bar-shaped trough 23, for being inserted rotation in it and cover plate 2 is rotated with nail or male member by user, is convenient to user's operation.

If do not consider the comfort level that user experiences, cover plate 2 lower surfaces also can be provided with the bar blocks towards lower convexity, and bar blocks equally also can be grasped rear rotation by user, realizes the rotation of cover plate 2.

As shown in Figure 5, the utility model also proposes a kind of electronic watch 200, comprise upper shell 4, also comprise above-mentioned drain pan 100, between upper shell 4 and drain pan 100, form the cavity volume of sealing, in cavity volume, be provided with electronic watch core 5 and battery (not marking in the drawings), battery and electronic watch core 5 are electrically connected.

The cavity volume that forms sealing between upper shell 4 and drain pan 100, the cavity volume of sealing can stop that extraneous water enters in it, electronic watch core 5 and battery in protection cavity volume, electronic watch 200 has water-proof function.

Electronic watch 200 is also because having adopted drain pan 100, when the battery in replacing cavity volume or storage card or sim card, do not need to take apart upper shell 4 and drain pan 100, only the cover plate 2 on drain pan 100 need be turned on, simple to operate, and can not affect sealing between upper shell 4 and drain pan 100.

Between housing 1 on drain pan 100 and cover plate 2, be provided with O-ring seal 3, make drain pan 100 also there is water-proof function.

Electronic watch core 5 is mainly comprised of electronic component, for electronic watch 200, moves.

These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
