[0029] like Figures 1-5As shown in the embodiment of this utility model, a multi-position adjustable key switch includes a switch base 10, a housing 20, an unlocking mechanism 30, and a triggering mechanism 40; the housing 20 is disposed on the switch base 10, the unlocking mechanism 30 is disposed inside the housing 20, and the triggering mechanism 40 is disposed inside the switch base 10, with one end of the unlocking mechanism 30 abutting against the triggering mechanism 40; the unlocking mechanism 30 includes a key 31, a lock cylinder 32, and a reset component 33, with one end of the key 31 being able to be embedded in the lock cylinder 32; the triggering mechanism 40... The mechanism 40 includes a trigger fixing member 41, a trigger abutment member 42, a trigger elastic member 43, a conductive sheet 44, and a conductive terminal 45. One end of the trigger elastic member 43 is sleeved on the trigger abutment member 42, and both ends of the trigger abutment member 42 can abut against the conductive sheet 44 and the lock cylinder 32 respectively along the trigger fixing member 41. When the lock cylinder 32 rotates, the trigger abutment member 42 can be energized when it abuts against the conductive terminal 45. When the trigger abutment member 42 abuts against the lock cylinder 32 in the opposite direction, the conductive terminal 45 is de-energized. In this embodiment, one end of the lock cylinder 32 can be inserted into the through groove 414 and connected to the trigger fixing member 41, so that one end of the trigger abutment member 42 sleeved on the trigger fixing member 41 abuts against the lock cylinder 32. When the lock cylinder 32 rotates, it can drive the trigger abutment member 42 to rotate along the trigger fixing member 41. The trigger abutment member 42 is provided with an abutment block 421 on the conductive sheet 44, and the two sides of the conductive sheet 44 are recessed in the middle to abut against the two sides of the conductive terminal 45. The structure is compact, the abutment sensitivity is strong, the wear of the conductive terminal 45 is effectively reduced, and the practicality is enhanced.
[0030] like Figure 1 As shown, the top of the switch base 10 is provided with a slot 11 and an identification slot 12, and the bottom of the switch base 10 is provided with a base plate 13. The base plate 13 is provided with a fixing slot 14 and a fixing pin 15. One end of the fixing pin 15 can be sleeved on the trigger elastic element 43. In this embodiment, the slot 11 facilitates the sleeve of the outer shell 20 onto the switch base 10, and the buckle 22 and the slot 11 cooperate with each other to fix it to the switch base 10 and the outer shell 20. The identification slot 12 on the switch base 10 and the outer shell 20 facilitates the identification of the outer shell 20, enhancing practicality and aesthetics.
[0031] The outer surface of the housing 20 is provided with mounting threads 21. A snap fastener 22 and an identifier 23 are provided on the lower side of the mounting threads 21. One end of the snap fastener 22 engages with a slot 11, and one end of the identifier 23 can be embedded in an identifier slot 12 to fix the switch base 10 and the housing 20. In this embodiment, the mounting threads 21 facilitate the installation and fixing of the multi-position adjustable key switch for its use.
[0032] like Figure 3As shown, the housing 20 has a mounting groove 24 inside, and a limiting strip 25 is provided inside the mounting groove 24. The mounting groove 24 is used to install the lock cylinder 32, and the limiting strip 25 limits its position. In this embodiment, the mounting groove 24 facilitates the installation of the lock cylinder 32, enhancing the structural compactness of the housing 20 and the lock cylinder 32, enhancing the sensitivity of the unlocking mechanism 30, and preventing jamming from affecting the use of the multi-position adjustable key switch. Furthermore, the limiting strip 25 facilitates the limiting of the installation of the lock cylinder 32, enhancing the compactness of the internal structure, and allowing the triggering structure to form a sealed structure inside the housing 20, effectively preventing external moisture and debris from affecting the use of the triggering mechanism 40, thus demonstrating strong practicality.
[0033] like Figures 4 to 5 As shown, the bottom of the trigger fixing member 41 is provided with a conductive pin 441, and trigger grooves 412 are provided on both sides of the conductive pin 441. In this embodiment, the conductive pin 441 facilitates the enhancement of the contact area of the trigger mechanism, so as to enhance the stability of the internal structure of the switch base and improve the contact sensitivity.
[0034] The trigger fixing member 41 has a sliding groove 413 on its outer side and a through groove 414 in its middle. One end of the reset member 33 is sleeved on the trigger fixing member 41, and one end of the lock cylinder 32 can be inserted into the through groove 414. One end of the trigger elastic member 43 is disposed in the through groove 414 and connected to the lock cylinder 32. In this embodiment, the sliding groove 413 allows the trigger abutment member 42 to abut against the unlocking mechanism 30 and the conductive sheet 44 respectively along the trigger fixing member 41 within the sliding groove 413, enabling the multi-position adjustable key switch to be energized and de-energized. This enhances the internal structural compactness and abutment sensitivity of the multi-position adjustable key switch, making it highly practical.
[0035] One end of the trigger abutment 42 is sleeved on the trigger fixing member 41. Symmetrically arranged abutment blocks 421 are provided on both sides of the trigger abutment 42, and the two sides of the abutment blocks 421 are beveled. In this embodiment, the trigger fixing member 41 is cylindrical, allowing the trigger abutment 42 to rotate along the trigger fixing member 41. During rotation, it abuts against the unlocking mechanism 30 and the conductive sheet 44, respectively, enabling the multi-position adjustable key switch to be energized and de-energized. The abutment blocks 421 on both sides of the trigger abutment 42, with their curved beveled sides, facilitate close contact with the conductive sheet 44, enhancing conductivity and reducing wear on the conductive sheet 44.
[0036] The conductive sheet 44 has conductive pins 441 at both ends, and one end of the conductive pin 441 can be embedded in the trigger groove 412. In this embodiment, the conductive pins 441 help to improve the conductivity and sensing of the conductive sheet 44, and the fact that one end of the conductive pin 441 can be inserted into the trigger groove 412 effectively enhances the structural stability between the conductive sheet 44 and the trigger mechanism 40, and enhances the compactness between the trigger mechanism 40 and the conductive terminal 45.
[0037] The conductive sheet 44 is recessed in the middle and has a through hole 442, which can be inserted into the fixing pin 15. In this embodiment, the conductive sheet 44 is inserted into the switch base 10 through the through hole 442. The switch base 10 also has fixing grooves 14, and the number of fixing grooves 14 is the same as the number of conductive terminals 45, so that one end of the conductive terminal 45 can be inserted into the fixing groove 14 for power connection. The overall structure is compact and highly practical.
[0038] In an embodiment of this utility model, a multi-position adjustable key switch includes a switch base 10, a housing 20, an unlocking mechanism 30, and a triggering mechanism 40. The housing 20 is disposed on the switch base 10, the unlocking mechanism 30 is disposed inside the housing 20, and the triggering mechanism 40 is disposed inside the switch base 10. One end of the unlocking mechanism 30 abuts against the triggering mechanism 40. The unlocking mechanism 30 includes a key 31, a lock cylinder 32, and a reset member 33. One end of the key 31 can be embedded in the lock cylinder 32. The triggering mechanism 40 includes a trigger fixing member 41, a trigger abutment member 42, a trigger elastic member 43, a conductive sheet 44, and a conductive terminal 45. One end of the trigger elastic member 43 is sleeved on the trigger abutment member 42, and both ends of the trigger abutment member 42 can abut against the conductive sheet 44 and the lock cylinder 32 respectively along the trigger fixing member 41. When the lock cylinder 32 is rotated to lock, one end of the trigger abutment member 42... When the trigger abutment 42 is in contact with the conductive terminal 45, it can be energized. When the lock cylinder 32 is rotated to unlock, one end of the trigger abutment 42 abuts against the lock cylinder 32 in the opposite direction, causing the conductive terminal 45 to be de-energized. It is fixed to the switch base 10 by the housing 20 to enhance the compactness of the unlocking mechanism 30 and the triggering mechanism 40, improve the sensitivity of the unlocking mechanism 30 and the triggering mechanism 40, so as to improve the energization and de-energization sensitivity of the multi-position adjustable key switch and enhance the safety of personnel use. The triggering mechanism 40 is provided with a trigger abutment 42 that can rotate along the trigger fixing member 41 to abut against the conductive plate 44. The trigger abutment 42 is provided with a corresponding abutment block 421 that abuts against the conductive plate 44. The abutment block 421 is inclined to increase the abutment area. By rotating the trigger abutment 42 to abut against the conductive plate 44 to energize, the wear between the trigger abutment 42 and the conductive plate 44 can be reduced, the service life can be increased, and the practicality is strong.
[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
