Abstract
The utility model provides a kind of engineering mechanical instruments upper cover, including main body；Display screen, alarm lamp are installed, by keypad in the main body, by button is equipped on keypad, the lower end is equipped with microswitch, and microswitch is connect with circuit board, and the button includes pivoted loop and top stem casing, and mandril is equipped in top stem casing.Button is connect by the utility model the utility model using pivoted loop with upper cover, reduces the processing cost of former button set, avoids the possibility that button set shakes, and monoblock instrument reduces a kind of material that required precision is high；Cost is lower, and instrument assembly is simpler；Instrument will not have abnormal sound because button covers.
Description
Technical field
The utility model is related to a kind of engineering mechanical instruments upper covers.
Background technology
When microswitch coordinates with button set, best state is interference fit so that button set is firmly fixed on micro-
On dynamic switch, the stability (not loosening) of button can guarantee, but since the fine motion for being used as keypress function on engineering mechanical instruments is opened
Pass size is smaller, smaller with button set cooperation, to protect positive microswitch and be both interference fit with button set and fill
On, the height of required precision extremely increases production cost；Meanwhile if precision does not reach requirement, it will occur not filling or
Between coordinate, if undersized, button set can not be assembled with microswitch, if button set it is oversized, button set can be held in fine motion
It is in active state and (when practical set, can ensure there are minim gap between key panel and button set in pass and key panel
Button effect), under this state, complete assembly instrument, due to button cover loosen, slightly shake will abnormal sound, generally will be considered that
It is off quality.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of engineering mechanical instruments upper cover.
The utility model is achieved by the following technical programs.
A kind of engineering mechanical instruments upper cover provided by the utility model, including main body；Be equipped in the main body display screen,
Alarm lamp presses keypad, and by button is equipped on keypad, the lower end is equipped with microswitch, and microswitch connects with circuit board
It connects, the button includes pivoted loop and top stem casing, and mandril is equipped in top stem casing.
The both ends of the main body are respectively arranged with left limit protrusion and right limit protrusion.
The pivoted loop is that both ends are separately connected top stem casing and the annulus by keypad.
It is described by being additionally provided with panel on keypad.
The left limit protrusion and right limit project through bolt and the lower cover of main body connects.
The beneficial effects of the utility model are：Button is connect by the utility model using pivoted loop with upper cover, is reduced
The processing cost of former button set, avoids the possibility that button set shakes, and monoblock instrument reduces a kind of object that required precision is high
Material；Cost is lower, and instrument assembly is simpler；Instrument will not have abnormal sound because button covers.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A of the utility model Fig. 1 to partial sectional view；
In figure：1- main bodys, 2- display screens, 3- alarm lamps, 4- press keypad, and 5- buttons, 6- top stem casings, 7- pivoted loops, 8- is micro-
Dynamic switch, 9- mandrils, 10- panels, 11- left limit protrusions, 12- right limit protrusions.
Specific implementation mode
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
A kind of engineering mechanical instruments upper cover, including main body 1；Display screen 2, alarm lamp 3, button are installed in the main body 1
Platform 4, by button 5 is equipped on keypad 4, the lower end is equipped with microswitch 8, and microswitch 8 is connect with circuit board, described
Button 5 includes pivoted loop 7 and top stem casing 6, and mandril 9 is equipped in top stem casing 6.
The both ends of the main body 1 are respectively arranged with left limit protrusion 11 and right limit protrusion 12.
The pivoted loop 7 is that both ends are separately connected top stem casing 6 and the annulus by keypad 4.
It is described by being additionally provided with panel 10 on keypad 4.
The left limit protrusion 11 and right limit protrusion 12 are connect by bolt with the lower cover of main body 1.
Original button set feature is connected directly between upper cover by the utility model by pivoted loop feature as shown in Figure 1
On, when top cover die is developed, straight forming, by structure as shown in the figure, when pressing key panel with hand, force effect is in upper cover
On button cover feature so that elastic deformation occurs for annular feature, is connected to upper cover, has the structure that former button covers feature past
Under be pressed on microswitch, complete one-touch operation.
