Problems solved by technology

When the original design structure is subjected to a hammer test on the emergency stop button, due to the different stroke positioning methods, it is easy to cause the impact force to be transmitted to the internal fixed parts, which affects the service life of the product.
In addition, when the button is installed, it is installed in a top-down manner. When the button is installed, glue needs to be coated on the thread to fasten the button and the transmission rod. The thread of the button in the prior art is an internal thread. Correspondingly, there is an external thread on the outer wall of the transmission rod. When too much glue is applied, the glue will overflow and drip into the waterproof ring between the outer wall of the transmission rod and the inner wall of the housing, thereby affecting the action of the waterproof ring.

Embodiment 1

[0021] An emergency stop button, such as figure 1 As shown, it is used to connect with the transmission rod 3 of the emergency stop button, including the button body. The bottom of the button body is provided with a connecting part for connecting with the transmission rod 3 and for matching with the groove arranged on the top of the shell 2 To limit the button stroke limiting rib 12 of the button pressing stroke. In this embodiment, it is preferable that the cross section of the stroke limiting rib 12 of the button is circular. In this embodiment, the preferred connecting portion is a protruding portion 11 with external threads, which is used for threaded connection with the threaded hole provided on the top of the transmission rod 3, and it is further preferred that the protruding portion is arranged on the stroke limiting rib of the key 12 at the center of the cross section. An annular rib 13 is provided between the protruding portion 11 with an external thread and the but...

Embodiment 2

[0028] This embodiment is basically the same as Embodiment 1, the difference is that in this implementation, the key travel limiting rib 12 includes two convex ribs with a circular arc-shaped cross section, the two convex ribs are arranged opposite, and the cross section is located at one circle on.

Abstract

The invention relates to a scram button key, and the scram button key is connected with a transmission rod (4) of a scram button. The scram button key comprises a key body, and the bottom of the key body is provided with a connection part connected with the transmission rod (4), and a key travel limiting rib (12) which is used for cooperating with a groove at the top of a housing (2) so as to limit the press travel of the key. Compared with the prior art, the scram button key is convenient to install, can effectively prolong the service life of the scram button, and effectively reduces the height of the scram button.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, and in particular relates to an emergency stop button key. Background technique [0002] The traditional emergency stop button generally uses a transmission rod to position the stroke of the button. The gap between the transmission rod and the bushing must be greater than the stroke of the button, so that the button needs to be designed to be relatively high. When the original design structure is subjected to a hammer test on the emergency stop button, due to the different stroke positioning methods, it is easy to cause the impact force to be transmitted to the internal fixed parts, which affects the service life of the product. In addition, when the button is installed, it is installed in a top-down manner. When the button is installed, glue needs to be coated on the thread to fasten the button and the transmission rod. The thread of the button in the prior art is an in...
