In addition, the both sides that the first engaging item 243 is provided with limit protrusion 246 are also respectively provided with limit hole 2432,
The second engaging setting of component 25 matches in the limit hole 2432, and with the outer wall of the upper casing 21, prevents upwards
When 21 internal direction of shell pressing described first engages item 243, engages item 243 by described first and be pressed into the upper casing 21.
More specifically, the second engaging component 25 includes that two structures are identical, and set up separately in corresponding limit hole 2432
In the second engaging item 251 and second spring 252, wherein the second engaging 251 activity of item is embedded in the limit hole
In 2432, and it is connected with the bottom of the limit hole 2432 by second spring 252.It is provided on the second engaging item 251
Positive stop strip 2511, be provided in the limit hole 2432 with 2511 matched card slot 2431 of the positive stop strip, and then prevent institute
It states the second engaging item 251 and is detached from the limit hole 2432.
Further, be additionally provided with third spring 3 on the lower casing 22, one end of the third spring 3 with it is described under
Shell 22 is connected, and the other end offsets with the upper casing 21, to assist upper lower casing 22 to detach.
In addition, it is arc-shaped structure, Jin Erfang that the second engaging item 251, which is detached from the end of one end of limit hole 2432,
Toilet states the second engaging item 251 and enters or be detached from the limit hole 2432.
More specifically, first snap fastener includes the first snap-latch piece 231, and one end of first snap-latch piece 231 is perpendicular
Straight to be arranged at 22 edge of the lower casing, the other end is provided with snap fit tabs 232, and the direction of the snap fit tabs 232 engages with first
The direction protrusion that hole 210 coordinates, and then when first snap fastener is matched with the first connecting hole 210, the engaging is convex
It plays 232 to offset with the hole wall of first connecting hole 210, and then the movement of the lower casing 22 is limited.
In addition, the top of the roof and first connecting hole 210 when the limit protrusion 246 on first snap-latch piece 231
When wall offsets, the second engaging card of component 25 is set in second connecting hole 211.
In addition, the shell 1 includes upper shell 11 and lower casing 12, it is provided in the upper shell 11 to house institute
The cavity of inner casing is stated, the lower casing 12 is detachably connected with upper shell 11, upper outer to install inner casing, while closed cavity
Shell 11 and the junction of lower casing 12 are provided with sealing ring 4, prevent liquid from entering in closed cavity.
The specific course of work of the present invention：The lower casing 22 is matched with the upper casing 21, first snap fastener with
Second snap fastener respectively enters in the cavity of the upper casing 21, it is described second engaging component 25 on first engaging item 243 by
It is retracted into accommodating cavity 245 in turn to squeezing, and during the second engaging item 251 setting engages item 243 described first, with
First engaging item 243 moves synchronously, and then when the first engaging item 243 enters accommodating cavity 245, the second engaging item 251
The extruding for receiving 245 side wall of accommodating cavity subsequently enters in limit hole 2432, with the continuation of movement first snap fastener
Fastened with the lower wall of the first connecting hole 210, realize engaging that can be preliminary, subsequent lower casing 22 continue to 21 matched side of upper casing
To movement, since the length of the first snap-latch piece 231 is less than the length of the second snap-latch piece 241, and then the card on the first snap-latch piece 231
It closes protrusion 232 to initially enter in the first connecting hole 210, and fastens with the bottom wall of the first connecting hole 210, as upper casing 21 is under
The lasting cooperation of shell 22, the snap fit tabs 232 are moved with the first snap-latch piece 231 in first connecting hole 210, when second
When snap fastener is matched with second connecting hole 211, described first engages extruding of the item 243 without 21 inner wall of upper casing,
And then accommodating cavity 245 is stretched out under the action of the first spring 26, and after stretching out accommodating cavity 245, the second engaging item 251 can be without
The extruding of 245 inner wall of accommodating cavity, and then limit hole 2432 is stretched out under the action of second spring 252, the second engaging item 251
It is matched with the outer wall of upper casing 21 across the second connecting hole 211, prevents the first engaging item 243 from entering under the extruding of external force accommodating
It is interior, at this point, the snap fit tabs 232 and the roof of first connecting hole 210 on the first snap-latch piece 231 offset, at third spring 3
In compressive state.Upper casing 21 fastens to form inner casing with lower casing 22 at this time, and the inner casing is placed in shell 1, and the first engaging
The card of item 243 is set in third connecting hole 111, and during card is set, the second engaging item 251 is outer with the upper casing 21 always
Wall matches, and prevents the first engaging item 243 completely into the accommodating cavity 245, is then mounted on lower casing 12 upper
On shell 11, and then complete entire installation steps.
When dismounting, lower casing 12 to be dismantled first, then the first engaging of pressing item 243, the first engaging item 243 is shunk, into
And it is detached from the third connecting hole 111.It is connected so that inner casing is released with shell 1.Then the first engaging of pressing item 243,
The second engaging of pressing item 251 while pressing the first engaging item 243 so that the second engaging item 251 enters in limit hole 2432,
And then squeeze the first engaging item 243 so that the first card can item enters in accommodating cavity 245 so that the second snap fastener and the
Two connecting holes 211 are detached from, and subsequent third spring 3 stretches, and lower casing 22 continues to move towards the direction detached with the upper casing 21, and first
Snap fit tabs 232 and the lower wall of the first connecting hole 210 on snap-latch piece 231 offset.And then again by upper casing 21 and lower casing 22
It is connected, prevents the two to be detached from too fast, prevent part from falling, subsequent pressing fastened raised 232 so that the first snap fastener and first
Connecting hole 210 is detached from, and then inner casing is dismantled.
In the present invention, different the first snap fastener and the second snap fastener of setting length, and then realize upper casing 21 with
Secondary engaging between lower casing 22 while when dismantling, carrying out secondary dismounting, rise slow so that the two is fixed more secured
Punching acts on, and preventing from directly dismantling causes part to fall.In addition, the second snap fastener includes the first engaging component and the second engaging
Component 25, first group of engaging component with the second connecting hole 211 and third connecting hole 111 to engage, and then by upper casing
21 are connected with lower casing 22, inner casing is connected with outer wall, and the setting of the second engaging component 25, match, prevent with 21 outer wall of upper casing
While the first engaging component is detached from the third connecting hole 111, it is detached from the second connecting hole 211.And third spring 3
Setting, to assist upper casing 21 to be detached with lower casing 22, at the same make first engaging component detached with the second connecting hole 211 after block
It closes protrusion 232 with the lower wall of the first connecting hole 210 to be close to, lower casing 22 is prevented to be directly separated with upper casing 21.
It these are only preferred embodiments of the present invention, be not intended to limit the implementation manners and the protection scope of the present invention, it is right
For those skilled in the art, it should can appreciate that and all be replaced with being equal made by description of the invention and diagramatic content
