Abstract
The utility model discloses a chimeric structure of an upper cover and a key of a calculator unit. The chimeric structure of the upper cover and the key of the calculator unit comprise the upper cover and the key. A hole is formed in the upper cover. The key is embedded in the hole. The upper cover and a chimeric place of the key are combined in a hooked mode and form a structure which is shaped like a Chinese character 'hui'. Due to the fact that the upper cover and the chimeric place of the key are combined in a hooked mode and form the structure which is like the Chinese character 'hui', good seal property is formed, and the seal property of the upper cover and the chimeric places of the key is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of loam cake and button of unit calculator, particularly relates to the embedded structure of a kind of loam cake and button.
Background technology
Existing unit calculator mainly comprises loam cake, drain pan, button, microswitch and circuit board.On cover and have the hole, button is entrenched in this hole, circuit board is arranged in the drain pan, microswitch is welded on the circuit board, thereby drives the microswitch action by pressing button after loam cake and drain pan fasten mutually, with the break-make of control electric signal.
But, the chimeric surface of button and loam cake is respectively the applying plane, the embedded structure of fitting in this plane, because sealing is relatively poor, in use be easy to advance impurity from water leaking-in between the binding face of button and loam cake or leakage, cause the circuit board short circuit, and then have influence on the normal use of unit calculator.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of loam cake of the unit calculator that can improve sealing and the embedded structure of button.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of loam cake of unit calculator and the embedded structure of button comprise loam cake and button, on cover and be provided with the hole, the button buckle is in this hole, mutually collude and be combined and be back-shaped structure at the chimeric place of described loam cake and described button.
The recessed folding of the hole wall in described hole forms ring groove, described button adopts dicyclo lid structure, described button has external annulus and internal ring wall, external annulus embeds in the above-mentioned ring groove and is against on the inside surface of bottom land of ring groove, the outwardly formation ring of internal ring wall boss, the ring boss is connected on the outside surface of bottom land of above-mentioned ring groove.
Described button is the button that silica gel is made.
After adopting said structure, the loam cake of unit calculator of the present utility model and the embedded structure of button have following beneficial effect:
One, mutually collude and be combined and be back-shaped structure at the chimeric place of loam cake and button, thereby form good sealing, can effectively guarantee the sealing at the chimeric position of loam cake and button.
Two, form the chimeric hermetically-sealed construction of twice between the chimeric position of button and loam cake, in the external annulus embedded rings groove and be against on the inside surface of bottom land of ring groove, ring boss on the internal ring wall is connected on the outside surface of bottom land of ring groove, and this double sealing structure has further improved again the sealing at the chimeric position of loam cake and button.
Three, button adopts silica gel to make, and its high resilience also has suitable rigidity cover so that be installed to easily by bond energy, and guarantee to press comfortable, good sealing effect.
Description of drawings
Fig. 1 is the structural representation of the embedded structure of the loam cake of unit calculator of the present utility model and button.
Among the figure:
Loam cake 1 hole 11
Ring groove 12 buttons 2
External annulus 21 internal ring walls 22
Ring boss 23
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, the loam cake of unit calculator of the present utility model and the embedded structure of button comprise loam cake 1 and button 2.
Loam cake 1 is provided with hole 11, and button 2 buckles are in hole 11, and mutually collude and is combined and is back-shaped structure at the chimeric place of loam cake 1 and button 2, and its concrete structure is as follows.
The recessed folding of the hole wall in hole 11 forms ring groove 12.Button 2 adopts dicyclo lid structure, have external annulus 21 and internal ring wall 22, in the external annulus 21 embedded rings grooves 12, and be against on the inside surface of bottom land of ring groove 12, internal ring wall 22 outwardly formation ring boss 23, ring boss 23 is connected on the outside surface of bottom land of ring groove 12.
As a preferred embodiment of the present utility model, button 2 adopts silica gel to make, and its high resilience also has suitable rigidity cover so that button 2 can be installed to easily, and guarantee to press comfortable, good sealing effect.
In the utility model, the chimeric surface of loam cake 1 and button 2 is corresponding respectively to form back-shaped embedded structure, thereby forms good sealing, can effectively guarantee the sealing at the chimeric position of loam cake 1 and button 2.Particularly, form the chimeric hermetically-sealed construction of twice between the chimeric position of button 2 and loam cake 1, in the external annulus 21 embedded rings grooves 12, and be against on the inside surface of bottom land of ring groove 12, ring boss 23 on the internal ring wall 22 is connected on the outside surface of bottom land of ring groove 12, and this back-shaped double sealing structure has further improved again the sealing at the chimeric position of loam cake 1 and button 2.
Above-described embodiment and accompanying drawing and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
