Fig. 2 is an assembly view of the present invention.
The reference signs are: the emergency stop device comprises an emergency stop button 1, a stainless steel spring 2, an emergency stop sleeve 3 and an emergency stop ejector rod 4.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and 2, the emergency tripping device of the present invention comprises an emergency stop button 1, a stainless steel spring 2, an emergency stop sleeve 3, and an emergency stop ejector rod 4. Referring to fig. 2, the emergency stop button 1 comprises an emergency stop button head 1-1 and an emergency stop button sleeve 1-2 connected to the rear thereof; the emergency stop sleeve 3 comprises an outer sleeve 3-1 and an inner sleeve 3-2, the outer sleeve 3-1 and the inner sleeve 3-2 are connected through the bottom 3-3 of the emergency stop sleeve, and a guide hole for the emergency stop ejector rod 4 to pass through is formed in the center of the bottom 3-3 of the emergency stop sleeve; the emergency stop ejector rod 4 comprises an ejector rod body 4-1 and an ejector rod head 4-2.
The installation mode is as follows: one end of the ejector rod body 4-1 is connected with the ejector rod head 4-2, and the other end of the ejector rod body 4-1 penetrates through a guide hole at the bottom 3-3 of the emergency stop sleeve and passes through the inner sleeve 3-2; the stainless steel spring 2 is sleeved on the ejector rod body 4-1, and the ejector rod body 4-1 penetrates through the emergency stop button sleeve part 1-2 and then is connected with the bottom of the emergency stop button head part 1-1; one end of the stainless steel spring 2 is propped against the head part 1-1 of the emergency stop button, and the other end is propped against the bottom part 3-3 of the emergency stop sleeve; the diameter of the scram button sleeve portion 1-2 is smaller than the diameter of the outer sleeve 3-1 and larger than the diameter of the inner sleeve 3-2.
Firstly, considering that the buttons on the market are usually made of plastic, field operators can easily crash the plastic when shaking the handcart, and the price is high, the emergency stop button 1 in the device is made of metal and is processed by a factory, so that the quality of the emergency stop button is improved while the cost is ensured. Secondly, considering that the existing emergency button is of a prominent type, field personnel are easy to miss during routine maintenance to cause accidental tripping, the device adopts an embedded type mode, and the emergency stop button 1 cannot be touched under normal conditions.
