Abstract
The present invention relates to a kind of intervention button keys, it is connect for the drive rod (3) with intervention button, including keying body, the bottom of keying body is equipped with the interconnecting piece for connecting with drive rod (3) and is used to cooperate with the groove being arranged at the top of shell (2) to limit the key stroke limit rib (12) of key press stroke.Compared with prior art, the present invention has many advantages, such as service life that is easy for installation, can effectively improving intervention button and intervention button height is effectively reduced.
Description
Technical field
The invention belongs to low voltage electrical apparatus technology fields, and in particular to a kind of intervention button key.
Background technique
Traditional scram button generally uses drive rod to carry out the positioning of button stroke, and the gap between drive rod and axle sleeve needs
Greater than the stroke of button, make button that need to be designed relatively high.Former design structure is when intervention button carries out Hammering Test, due to its row
The mode of Cheng Dingwei is different, is easy to cause impact force to be transferred to internal retaining element, influences product service life.Another button is being pacified
It when dress, is installed using top-down mode, in key installation, needs coating glue on screw thread, for fastening key
With drive rod, and the screw thread of key in the prior art be internal screw thread, correspondingly, drive rod lateral wall be equipped with external screw thread, when
When coating glue is excessive, it will lead to glue spilling, drip in the water proof ring between drive rod lateral wall and housing interior side-wall, thus
Influence water proof ring movement.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind is easy for installation, can
It effectively improves the service life of intervention button and the intervention button key of intervention button height is effectively reduced.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of intervention button key, connect, including keying body for the drive rod with intervention button, the keying body
Bottom be equipped with interconnecting piece for being connect with drive rod and for cooperating with the groove that cover top portion is arranged in limit key by
Press the key stroke limit rib of stroke.
Preferably, the circular in cross-section of the key stroke limit rib.
Preferably, the key stroke limit rib includes the convex ribs that multiple cross sections are in arc-shaped, and described is multiple convex
The cross section of muscle is located on a circle.
Preferably, the interconnecting piece is with externally threaded protrusion, which is used for and is arranged on drive rod top
The threaded hole in portion is connected through a screw thread.
Preferably, the interconnecting piece is with externally threaded protrusion, which is arranged in key stroke limit rib
At the center location of cross section, for being connected through a screw thread with the threaded hole being arranged at the top of drive rod.
Preferably, the bottom surface of keying body be additionally provided with for the actuating groove that matches at the top of drive rod.
Preferably, circular bar is equipped between the protrusion and key stroke limit rib, the actuating groove is ring
The annular groove formed between the lateral surface of shape muscle and the medial surface of key stroke limit rib.
Compared with prior art, the invention has the following advantages that
(1) by key stroke positioning bar, when so that the key being applied to intervention button, conventional button biography can effectively be avoided
Gap between lever and axle sleeve influences, and so that button is avoided the button interior part life that intervention button Hammering Test is influenced, mentions
High properties of product, reduce the height of product, save product cost.
(2) by the externally threaded protrusion of button design band, in corresponding drive rod medium design threaded hole, in
Between it is fixed, avoid other function part positions, to reduce product failure risk, improve product service life.
(3) when actuating groove of the invention enables to the key to be applied to intervention button, key, the actuating groove energy are pushed
Enough and drive rod carries out the transmission of power, and drive rod is pushed.And circular bar can further prevent glue to overflow, and drip to waterproof
On circle.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of intervention button key of the invention；
Fig. 2 is schematic diagram of main cross-sectional structure using intervention button of the invention.
In figure, 1 is key, and 11 is are key stroke limit rib with externally threaded protrusion, 12, and 13 be circular bar, and 2 be outer
Shell, 3 be drive rod, and 4 be push rod, and 41 is stop shelves, and 42 be spring, and 5 be axle sleeve, and 6 be torque spring, and 7 be screw, and 8 be water proof ring.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of intervention button key, as shown in Figure 1, for being connect with the drive rod 3 of intervention button, including keying body, it is described
The bottom of keying body be equipped with interconnecting piece for connect with drive rod 3 and for matching with the groove being arranged at the top of shell 2
It closes to limit the key stroke limit rib 12 of key press stroke.The cross section of preferred key stroke limit rib 12 in the present embodiment
It is rounded.The preferred interconnecting piece of the present embodiment is with externally threaded protrusion 11, which is used for setting at 3 top of drive rod
Threaded hole be connected through a screw thread, and further preferably the center of circle of 12 cross section of key stroke limit rib is arranged in the protrusion
At position.The present embodiment between externally threaded protrusion 11 and key stroke limit rib 12 be equipped with circular bar 13, circular bar
Annular groove between 13 lateral surface and the medial surface of key stroke limit rib 13 is formed for the top phase with drive rod 3
The actuating groove matched.
Using intervention button of the invention structural schematic diagram as shown in Fig. 2, by the key be applied to intervention button when, including
Following steps:
(1) first spring 42 is put into push-rod hole, then is squeezed spring 42 with shelves 41 are stopped, applied force make to stop shelves 41 into
Enter the operating position for stopping grade sliding slot, convolution upwards again, makes to stop shelves after rotation predetermined angle (the present embodiment preferably rotates to the left 40 °)
41 are in ready position, and the baffle 43 of 4 bottom of push rod is connect with the matching grooves that 5 bottom of axle sleeve is arranged at this time,；
