Description
Technical field
The utility model relates to a kind of press-key structure of control panel of microwave oven, belongs to the improvement technology of the press-key structure of control panel of microwave oven.
Background technology
The press-key structure of existing control panel of microwave oven as shown in Figure 1, comprise button 1, press key spring 2 and control box 3, wherein button 1 inboard is provided with more than one guiding cylindricality key pin 11 and two with upper limit buckle 12, offer mounting groove 4 on the control box 3, mounting groove 4 bottom surfaces are provided with through hole 5 and the hollow spring reference column 6 corresponding with the cylindricality key pin 11 of leading, be sleeved on the spring reference column 6 by key spring 2, button 1 is installed in the mounting groove 4, button 1 set spacing buckle 12 is installed in the set bayonet socket of mounting groove 4 inwalls, button 1 set guiding cylindricality key pin 11 passes hollow reference column 6 and stretches out through hole 5, an end of pressing key spring 2 contacts with the medial surface of button 1, the other end contacts with the bottom surface of mounting groove 4, there is following problem in this press-key structure: owing to limited by key stroke, the spring reference column is height-limited shorter, press key spring and be difficult for location and installation, the button spring travel is shorter simultaneously, need exert oneself during by button.
The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of easy for installation stable that button is the press-key structure of control panel of microwave oven easily.
The technical solution of the utility model is: a kind of press-key structure of control panel of microwave oven, comprise button, press key spring and control box, wherein the button inboard is provided with more than one guiding cylindricality key pin and two with the upper limit buckle, offer mounting groove on the control box, the mounting groove bottom surface is provided with through hole corresponding with the cylindricality key pin that leads and hollow spring reference column, the button spring housing is contained on the spring reference column, key device is in mounting groove, the set spacing buckle of button is installed in the set bayonet socket of mounting groove inwall, the set guiding cylindricality key of button was worn the hollow reference column and was stretched out through hole, an end of pressing key spring contacts with the medial surface of button, the root that it is characterized in that described spring reference column offers annular positioning groove to the mounting groove bottom surface, is against in the annular positioning groove by the other end of key spring.
The utility model is owing to adopt the root at the spring reference column to offer annular positioning groove to the mounting groove bottom surface, be against structure in the annular positioning groove by the other end of key spring, therefore, press easier location of key spring and installation, the button spring travel is increased, and button is very light.
