[0002] In the industrial production field, the stable operation of equipment is directly related to production efficiency and product quality, and the performance of the key as the core component of human-computer interaction of equipment is very important. However, the keys equipped in the current industrial equipment have the prominent problem of short service life, which brings many troubles to industrial production.

[0003] Industrial scenes are often accompanied by extreme working conditions such as high temperature, high humidity, strong corrosion and high dust. The commonly used plastic key is difficult to resist the erosion of harsh environment due to the limitation of the material itself. In chemical enterprises, a large amount of corrosive gas is generated in the production process, and the surface of the plastic key is quickly corroded when exposed to it for a long time. The key identification is quickly blurred, and even the structure is damaged, so that the key cannot normally respond to the operation instruction. In addition, the mechanical strength of the plastic material is poor, and the key is easily deformed under frequent pressing operation. The moving parts inside the key will also be jammed due to excessive wear, greatly affecting the use stability of the equipment.

[0004] Industrial operation needs workers to wear various protective gloves for operation due to safety considerations. However, protective gloves weaken the worker's perception of pressing force while providing protection. In a machine shop, it is difficult for workers to accurately control the pressing force of the key when operating the equipment due to the thickness of the gloves, and the plastic key is often broken and the internal parts are damaged due to excessive force. This not only causes equipment downtime and maintenance, delays production progress, and increases maintenance costs, but also may cause safety accidents due to equipment failure.

The three rotary grooves 10 are three groups of spiral guide grooves, the three rotary clamping heads 11 are clamped in the three rotary grooves 10, when the button core 4 moves relatively deep to the rotating sleeve 9, the button core 4 rotates relatively to the rotating sleeve 9, because the limiting protrusion 14 and the limiting port 15 cooperate to prevent the rotating sleeve 9 from rotating relatively to the structure shell 2, after the rotating sleeve 9 cannot rotate, the button core 4 must rotate when the button is pressed.

[0028] Further, the locking part 7 comprises a locking sleeve 16, a locking head 19, a locking sleeve connecting ring 20 and a clamping groove 21. The locking sleeve 16 is arranged on the side of the key core 4 away from the rotating part 6. A plurality of groups of first locking openings 17 are formed in the locking sleeve 16.

The locking head 19 is clamped in the first locking opening 17. The key core 4 drives the locking sleeve 16 to rotate. Since the depth of the first locking opening 17 is smaller than that of the three spiral grooves 10, the locking head 19 is still rotated when it is separated from the first locking opening 17. After the locking head 19 is separated, the locking sleeve 16 does not rotate with the key core 4. The locking head 19 is rotated to be opposite to the second locking opening 18.

[0052] Structural plate 22: Set on one side of the key core 4, fixed in the structural shell 2 through the adhesive mounting ring 25, used for installing the electrical contact 23 to realize electrical connection;

[0053] Electrical contact 23: Set on the side of the structural plate 22 close to the key core 4, in contact or separated from the electrical contact piece 24 to realize the on-off of the circuit;

[0054] Electrical contact piece 24: Set at the end of the key core 4, in contact with the electrical contact 23 on the structural plate 22 to connect the circuit and control the conduction state of the circuit;

[0055] Adhesive mounting ring 25: Set in the structural shell 2, used to fix the structural plate 22 close to the end of the key core 4;

[0056] Movable cavity 26: Set in the side of the structural shell 2 close to the pressing head 1, to provide space for the movement of the pressing head 1;

[0057] The limiting female groove 27 is arranged on the side wall of the movable cavity 26 and cooperates with the limiting male ring 28 on the outer side of the pressing head 1, so as to ensure the stable linear movement of the pressing head 1.

[0058] The limiting male ring 28 is arranged on the outer side of the pressing head 1 and is slidably connected in the limiting female groove 27, so as to limit the movement track of the pressing head 1 and make it move stably.

[0059] Working principle: when the user presses the press head 1, the press head 1 moves along the movable cavity 26 near the press head 1 side of the structure shell 2 under the action of external force, the limiting male ring 28 is constrained in the limiting female groove 27, which ensures the stable linear motion of the press head 1, and then pushes the key core 4 to move in the structure shell 2. In the process of the key core 4, the rotating part 6 begins to play a role. The three spin clamps 11 on the key core 4 slide along the three spin grooves 10 in the rotating sleeve 9. Because the three spin grooves 10 are three groups of spiral guide grooves, the key core 4 rotates relative to the rotating sleeve 9 while moving in. The limiting hole 15 on the rotating sleeve connecting ring 12 on the outside of the rotating sleeve 9 cooperates with the limiting protrusion 14 of the limiting ring 13 in the structure shell 2, preventing the rotating sleeve 9 from rotating relative to the structure shell 2. When the rotating sleeve 9 cannot rotate, the key core 4 can only rotate itself when it continues to press. With the continuous pressing of the key core 4, its motion is transmitted to the locking part 7. The lock head 19 on the key core 4 is originally clamped in the second lock hole 18 of the locking sleeve 16. In the process of the key core 4 moving in and rotating, the lock head 19 is separated from the second lock hole 18 and rotates to the opposite side of the first lock hole 17. At this time, if the key is released, the key core 4 will move towards the press head 1 under the action of the spring 5, and the lock head 19 will be clamped in the first lock hole 17, driving the locking sleeve 16 to rotate with the key core 4, completing the switching of the locking state, the electric contact 24 and the electric contact 23 are separated, and the circuit is disconnected. When the electric contact 24 at the end of the key core 4 contacts with the two groups of electric contacts 23 on the structure plate 22 in the electric connection part 8, the two groups of electric contacts 3 on the other side of the structure plate 22 are connected, and the circuit is successfully connected. In the locked state, the electric contact 24 continuously contacts with the electric contact 23, maintaining the long-time conduction of the circuit. If you need to lock, press the press head 1 again, and the key core 4 moves in again. Because the depth of the first lock hole 17 is less than that of the three spin grooves 10, the lock head 19 will still rotate when it is separated from the first lock hole 17. At this time, the locking sleeve 16 does not rotate with the key core 4. The lock head 19 rotates to the second lock hole 18, and after releasing the key, the lock head 19 is clamped in the second lock hole 18, the electric contact 24 contacts with the electric contact 23, maintains the electrical connection, and realizes the circuit locking. In the whole process, the spring 5 plays a key role in resetting. In the non-locking state, one end of the spring 5 abuts against the rotating sleeve 9, and the other end abuts against the key core 4. When the pressing force disappears, the spring 5 releases the elastic force, pushes the key core 4 to reset, and drives the press head 1 to rise to the initial position. In summary, the metal spring reset key realizes the on-off control and locking function of the circuit in a pure mechanical way through the close cooperation of the press head 1, the key core 4, the rotating part 6, the locking part 7 and the electric connection part 8, and relies on the metal mechanical structure to effectively ensure the durability and long service life of the product.
