Description
Technical field
Household appliance technical field is the utility model is related to, more particularly to a kind of opening structure.
Background technology
Micro-wave oven is that kitchen range are cooked in a kind of modernization with microwave heating of food.With the improvement of living standards, micro-wave oven
Be consumed in terms of Design and Features and show clear superiority.
The door-opening mode of microwave current stove is mainly shown as sliding door type and button.Because button micro-wave oven operates letter
It is single, and have no to stop between consumer and micro-wave oven furnace chamber, can closely take thing, therefore button micro-wave oven from the first generation just
Use till today.
In existing technology, the opening structure of micro-wave oven generally includes panel and the button being arranged on panel.Wherein,
Button includes generally including keycap and the push rod being connected on keycap, and push rod penetrates the push hole being arranged on panel, for promoting
Opening lever installed in push hole rear.And the opening lever promoted can be then driven and open the door of micro-wave oven.
Because the gap of push rod and push hole is larger, therefore the opening structure of prior art, its button more loosens, to key
When the edge of cap applies pressing force, it is also easy to cause the keycap of button to tilt.If however, reduce the gap of push rod and push hole,
Again easily because frictional force is too high, push rod, which blocks, causes keys deactivation.The increased limit on the basis of the opening structure of prior art
The structures such as position buckle, cause the installation of button to become very loaded down with trivial details again.
Utility model content
A kind of opening structure is the utility model is related to, also there is very high reliability on the basis of simple in construction.
In order to solve the above-mentioned technical problem, the utility model provides a kind of opening structure, including：
Button, possess：Keycap, the guide-localization post being arranged on keycap, the spring being socketed on guide-localization post and
The push rod being arranged on keycap.Panel, push hole and guide-localization hole are provided with panel.Push rod penetrates push hole and opened the door
Action.Guide-localization post penetrates guide-localization hole, and can be moved in guide-localization hole interior edge its length direction, and spring is used for
Keycap is exerted a force to the direction away from guide-localization hole.
By the guide-localization post being arranged on keycap, movement position and the direction of motion to keycap are carried out the utility model
It is effective spacing, pass through the spring being socketed on guide-localization post, there is provided the power of keycap resilience.Relative to prior art
For, the utility model after the direction of motion of keycap obtains control, can effectively be prevented under the position-limiting action of guide-localization post
Only keycap tilts.Moreover, the cooperation by guide-localization post and push rod so that the gap of push rod and push hole can be come as needed
Set, avoid the problem of push rod blocks, possess higher reliability.
Preferably, guide-localization post is parallel to each other with push rod on the direction perpendicular to keycap.When the two is parallel to each other,
Motion of the guide-localization post with push rod on panel is not susceptible to hinder, and possesses more preferable harmony.
Further, preferably, guide-localization post is located at the center of keycap.Guide-localization positioned at the center of keycap
Post, the uniform force of keycap can be improved, further prevents keycap from tilting.
In addition, preferably, multiple push rods are provided with a manner of across guide-localization post.Set multiple push rods can be
The stress of keycap is equably shared in multiple directions, reliability is improved and increases the service life.
In addition, preferably, push rod is located at the center of keycap, guide-localization post is with push rod on the direction perpendicular to keycap
It is parallel to each other.When push rod to be arranged on to the center of keycap, it is only necessary to a push rod is set, therefore simplifies corresponding be used for
The structure of the mechanism of door opening action, reduces cost.
In addition, preferably, the side wall in push rod is provided with holding section, in push hole formed with engaged part, moved in push rod
Holding section and engaged part are mutually clamped and limit displacement of the keycap in the direction of motion of guide-localization post when making.When release is pressed
During key, the holding section set in the side wall of push rod can prevent button from departing from panel.Using the holding section that is arranged on push rod and
Engaged part in push hole limits the motion of keycap, because holding section and engaged part are not touched with spring interface, therefore has
There is good reliability.
In addition, preferably, in the periphery of guide-localization post formed with salient rib or recess, in guide-localization hole
Form the groove coordinated with salient rib or form the lug boss coordinated with recess.By the salient rib that is correspondingly arranged and recessed
Groove, or the recess and lug boss being correspondingly arranged, guide-localization post can be formed directly into guide-localization hole, improve guiding
The contact area of positioning hole and guide-localization post, can further prevent the tilting of keycap and jumping for push rod.
In addition, preferably, it is arranged at key formed with the keyway for accommodating button, push hole and guide-localization hole in panel
In groove.By setting keyway preferably to accommodate keycap on panel, prevent keycap from tilting.
In addition, preferably, push hole is extended from the surface of panel and forms projection, so as to which the motion to push rod is drawn
Lead.Raised push hole extends the shift length of pushrod movement, and then improves force stability.
In addition, preferably, guide-localization hole is extended from the surface of panel and forms projection, so as to guide-localization post
Motion guide.Raised guide-localization hole extends the shift length of guide-localization post motion, equally also improve by
Power stability.
