In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0060] Please see Figure 1 , Figure 2 , Figure 7 and Figure 11This utility model provides a multi-signal activated safety lock 100, which includes a housing 10, a switching mechanism 20, and a button component 30. The switching mechanism 20 is located inside the housing 10 and includes a circuit board 21, a micro switch 22, and a reed switch 23. Both the micro switch 22 and the reed switch 23 are electrically connected to the circuit board 21, which is used for electrical connection to electrical equipment. The button component 30 is connected to the housing 10 and can move relative to the housing 10 between a stop position and a start position under external force. The button component 30 has a first actuating block 33 and a second actuating block 34. When the button component 30 moves from the stop position to the start position, the first actuating block 33 can change the switching state of the micro switch 22, and the second actuating block 34 can change the switching state of the reed switch 23.

[0061] Specifically, the housing 10 can be mounted on the surface of the electrical equipment using components such as clips and screws to facilitate electrical connection between the switching mechanism 20 and the electrical equipment. The circuit board 21 can be electrically connected to the electrical equipment via cables, metal contacts, or other means. The circuit board 21 can send electrical signals to the electrical equipment that can change its electrical state. The electrical state can be the on / off state of the electrical equipment, meaning the electrical equipment can switch between an on, off, and standby state via the switching mechanism 20. The electrical state can also be the operating mode of the electrical equipment, meaning the electrical equipment can switch between a test mode and a processing mode via the switching mechanism 20.

[0062] Specifically, the button component 30 is movably connected to the housing 10, and the user can move the button component 30 from the stop position to the start position by applying pressure to the button component 30.

[0063] Specifically, the blocking member 40 is movably connected to the housing 10. When the user inserts the start key 50 into the housing 10, the start key 50 can apply a force such as torque, thrust, or pull to the blocking member 40, causing the blocking member 40 to move from the first position to the second position.

[0064] Specifically, when the button component 30 is in the stop position, the button component 30 has not yet triggered the switch mechanism 20, and the electrical state of the electrical equipment remains unchanged. Figure 7 ).

[0065] It should be noted that when the button component 30 moves from the stop position to the start position, the first actuation block 33 can either trigger the micro switch 22, activating the corresponding circuit of the micro switch 22, or deactivate the micro switch 22, deactivating its corresponding circuit. Similarly, when the button component 30 moves from the stop position to the start position, the second actuation block 34 can either trigger the reed switch 23, activating its corresponding circuit, or deactivate the reed switch 23, deactivating its corresponding circuit.

[0066] By setting a first start block 33 and a second start block 34 on the button component 30, and setting a micro switch 22 and a reed switch 23 on the circuit board 21, when the user applies external force to the button component 30, the button component 30 can move relative to the housing 10, and the first start block 33 changes the switching state of the micro switch 22, and the second start block 34 changes the switching state of the reed switch 23, thereby changing multiple circuit states of the electrical equipment at the same time, which can meet a variety of control requirements and has strong applicability.

[0067] In one embodiment of this implementation, please refer to Figure 7 and Figure 11 The micro switch 22 includes a switch housing 221, a contact selection component 222, and a trigger block 223. The contact selection component 222 is disposed inside the switch housing 221 and connected to the circuit board 21. The trigger block 223 is slidably engaged with the switch housing 221 and connected to the contact selection component 222. A first actuating block 33 is used to push the trigger block 223 to slide relative to the switch housing 221, so as to cause the contact selection component 222 to selectively conduct the circuit on the circuit board 21. With this configuration, the button component 30 can selectively conduct the circuit of the circuit board 21 through the micro switch 22.

[0068] Specifically, one end of the trigger block 223 is located inside the switch housing 221 and abuts against the contact selection member 222, while the other end of the trigger block 223 is exposed outside the switch housing 221 for the first start block 33 to push.

[0069] Specifically, the contact selection component 222 includes a moving contact connected to contact c, a stationary contact connected to contact a, and a stationary contact connected to contact b. The moving contact is connected to the switch housing 221 by a spring and abuts against the trigger block 223, so that the trigger block 223, when pushed by the button component 30, can push the spring to move the moving contact to select and contact one of the stationary contacts, thus connecting the corresponding circuit. When the button component 30 is in the stop position, the first starting block 33 has not yet pushed the trigger block 223, and at this time, the corresponding circuits of contacts a and c in the contact selection component 222 are connected. When the button component 30 is in the start position, the first starting block 33 pushes the trigger block 223 to connect the corresponding circuits of contacts b and c in the contact selection component 222.

[0070] In one embodiment of this implementation, please refer to Figure 7 and Figure 11 The reed switch 23 includes a first reed 231 and a second reed 232, which are arranged opposite to each other and both connected to the circuit board 21. When the button component 30 is in the stop position, the second actuating block 34 separates the first reed 231 and the second reed 232. When the button component 30 is in the start position, the first reed 231 and the second reed 232 return to their elastic deformation and abut against each other. This configuration allows the button component 30 to selectively turn on or off the corresponding circuit of the circuit board 21 via the reed switch 23.

[0071] In one embodiment of this implementation, a connector 211 is provided on the bottom side of the circuit board 21. The top end of the connector 211 passes through the circuit board 21 and is connected to the micro switch 22 and the reed switch 23. The bottom end of the connector 211 passes through the housing 10 and is used for electrical connection with electrical equipment. This arrangement facilitates the electrical connection of the circuit board 21 with electrical equipment.

[0072] Please refer to the following for details. Figure 17 and Figure 18 Connector 211 provides corresponding contacts for micro switch 22 and reed switch 23 and is used to connect to adapter 200.

[0073] The structure of the blocking member 40 and the start key 50 in one embodiment of this invention will be described below.

[0074] In one embodiment of this implementation, please refer to Figures 1 to 11 The multi-signal start type safety lock 100 includes a blocking member 40 and a start key 50. The blocking member 40 is connected to the housing 10 and is movable relative to the housing 10 between a first position and a second position. Specifically, when the blocking member 40 is in the first position, it is located on the trigger path of the button member 30 moving from the stop position to the start position. Figure 6 When the blocking member 40 is in the second position, the blocking member 40 is outside the trigger path. Figure 10 The start key 50 can extend into the housing 10 and switch the blocking member 40 from the first position to the second position.

[0075] By setting a blocking member 40, the blocking member 40 can move between a first position and a second position relative to the housing 10. Before the user inserts the start key 50 into the housing 10, the blocking member 40 is in the first position, located on the trigger path of the button member 30, to prevent the button member 30 from moving to the start position. The user cannot trigger the switch mechanism 20 by pressing the button member 30, and the electrical state of the electrical equipment remains unchanged. The switch member is not easily triggered by mistake, thus having high safety. When the user inserts the start key 50 into the housing 10, the blocking member 40 can switch from the first position to the second position, and the blocking member 40 leaves the trigger path of the button member 30. The user can press the button member 30 to the start position to trigger the switch mechanism 20, thereby changing the electrical state of the electrical equipment. This process relies only on mechanical movement and does not require magnetic actuation, so the cost is low and the reliability is high.

[0076] The specific structure of the housing 10 in one embodiment of this invention will be described below.

[0077] In one embodiment of this implementation, please refer to Figures 1 to 4 The housing 10 includes an upper housing 11, a middle housing 12, and a lower housing 13. The upper housing 11 and the lower housing 13 are connected by snap-fit ​​and enclose a mounting cavity capable of accommodating other components. The middle housing 12 is located within the mounting cavity and is fixed to the lower housing 13. The blocking member 40, the button member 30, and the switching mechanism 20 are all mounted on the middle housing 12. The bottom of the lower housing 13 is used to mount an adapter 200, which transmits signals from the switching mechanism 20 to electrical equipment.

[0078] Please refer to the following in this embodiment: Figure 12 and Figure 13 The upper shell 11 includes an upper shell body 111, a rigid button block 112, and a soft elastic layer 113. The upper shell body 111 has a mounting hole 1111, the soft elastic layer 113 is installed in the mounting hole 1111, and the rigid button block 112 is embedded in the soft elastic layer 113, with the bottom side of the rigid button block 112 abutting against the top side of the button component 30. The rigid button block 112 is used for user pressing and transmits the force generated by the pressing to the button component 30, causing the button component 30 to move relative to the shell 10. The rigid button block 112 is mounted on the upper shell body 111 through the soft elastic layer 113. On the one hand, the soft elastic layer 113 can deform to provide a certain displacement for the rigid button block 112, allowing the rigid button block 112 to drive the button component 30 to move. On the other hand, the gaps between the soft elastic layer 113 and the mounting hole 1111, as well as the gaps between the soft elastic layer and the rigid button block 112, can be sealed by compression, improving waterproof and dustproof performance.

[0079] Please refer to the following in this embodiment: Figures 12 to 16The lower shell 13 has a ring rib 131, and the upper shell 11 is fitted over the outside of the ring rib 131 and connected to the ring rib 131 by a snap fastener. With this arrangement, external moisture, dust and other debris are less likely to enter the mounting chamber through the gap between the lower shell 13 and the upper shell 11, thus improving the sealing performance of the shell 10.

[0080] Please refer to the following in this embodiment: Figures 12 to 16 A sealing groove 1131 is formed on the bottom side of the soft elastic layer 113, and a sealing protrusion 1311 is formed on the top side of the rib 131. The shape of the sealing protrusion 1311 matches the shape of the sealing groove 1131. The sealing protrusion 1311 extends into the sealing groove 1131 and presses against the inner wall of the sealing groove 1131. With this arrangement, the lower shell 13 and the soft elastic layer 113 can make full contact, further reducing the risk of foreign matter entering the installation chamber and improving the sealing performance of the shell 10.

[0081] Please refer to the following in this embodiment: Figure 17 and Figure 18 The bottom side of the lower shell 13 is provided with an assembly groove 106 for the adapter 200 to be inserted and electrically connected to the switching mechanism 20. The side wall of the assembly groove 106 is provided with a second sealing ring 105, which abuts against the adapter 200 to seal the gap between the adapter 200 and the side wall of the assembly groove 106, thereby improving the reliability of the electrical connection.

[0082] In this embodiment, please refer to Figure 4 A gasket 17 is fitted on the outer side of the upper shell 11, and the gasket 17 is used to abut against the surface of the electrical equipment.

[0083] The specific structure of the blocking member 40 in one embodiment of this invention will be described below.

[0084] In one embodiment of this implementation, please refer to Figures 5 to 11 The direction in which the button component 30 moves relative to the housing 10 is defined as the first direction. The blocking component 40 is connected to the housing 10 in a second direction that is movably relative to it, and the second direction intersects with the first direction. This arrangement allows the blocking component 40 to move along the second direction to the trigger path of the button component 30 or to leave the trigger path.

[0085] In this embodiment, the middle shell 12 of the housing 10 is provided with a first sliding groove 104 extending in the second direction, and the blocking member 40 slides in the first sliding groove 104 so as to realize that the blocking member 40 and the housing 10 can be connected to each other in the second direction.

[0086] In this embodiment, the second direction is perpendicular to the first direction.

[0087] In one embodiment of this implementation, please refer to Figures 5 to 11A first elastic element 41 is provided between the blocking member 40 and the housing 10. The first elastic element 41 applies an elastic force to the blocking member 40 to move it from the second position to the first position. With this configuration, after the user removes the start key 50 from the housing 10, the blocking member 40 can be reset from the second position to the first position under the action of the first elastic element 41, so as to restore its obstruction of the button member 30.

[0088] In this embodiment, the blocking member 40 has a spring groove, and the first elastic element 41 is constructed as a spring. One end of the spring abuts against the middle shell 12, and the other end of the spring is accommodated in the spring groove and abuts against the bottom wall of the spring groove. The spring is in a compressed state to provide sufficient elastic force to the blocking member 40.

[0089] In one embodiment of this implementation, please refer to Figures 5 to 11 The housing 10 has a slot 101, and a through hole 102 is formed on the side wall of the slot 101. One end of the blocking member 40 extends into the slot 101 through the through hole 102. When the start key 50 is inserted into the slot 101, it can push one end of the blocking member 40 to move the blocking member 40 from the first position to the second position. With this configuration, the user can move the blocking member 40 from the first position to the second position while inserting the start key 50 into the slot 101. When the start key 50 is in the slot 101, the start key 50 can prevent the blocking member 40 from returning from the second position to the first position, so that the user can trigger the switch mechanism 20 by pressing the button member 30.

[0090] In this embodiment, the start key 50 has an inclined surface 501 that can abut against the blocking member 40, so as to convert the force of the user inserting the start key 50 into the thrust of the blocking member 40, and to make the movement of the blocking member 40 from the first position to the second position smoother.

[0091] In this embodiment, the inner wall of the through hole 102 is provided with a first sealing ring 103. The first sealing ring 103 is sleeved on the outer periphery of the blocking member 40 to seal the gap between the blocking member 40 and the through hole 102, thereby reducing the risk of debris entering the installation chamber from the slot 101 and the through hole 102.

[0092] The specific structure of the blocking member 40 in another embodiment of this invention will be described below.

[0093] In one embodiment of this implementation, please refer to Figures 30 to 32 The direction in which the button component 30 moves relative to the housing 10 is defined as the first direction. The blocking component 40 is rotatably connected to the housing 10 about a first axis, which intersects the first direction. This arrangement allows the blocking component 40 to rotate about the first axis to the trigger path of the button component 30 or to leave the trigger path.

[0094] In this embodiment, the blocking member 40 is provided with a rotating shaft 47 that rotatably engages with the housing 10, and the axis of the rotating shaft 47 itself is the first axis. The first axis is perpendicular to the first direction.

[0095] In one embodiment of this implementation, please refer to Figures 30 to 32 The housing 10 has a slot 101, and a through hole 102 is formed on the side wall of the slot 101. One end of the blocking member 40 extends into the slot 101 through the through hole 102. When the start key 50 is inserted into the slot 101, it can push one end of the blocking member 40 to rotate the blocking member 40 from the first position to the second position. This configuration allows the user to rotate the blocking member 40 from the first position to the second position while inserting the start key 50 into the slot 101. When the start key 50 is in the slot 101, the start key 50 can prevent the blocking member 40 from returning from the second position to the first position, so that the user can trigger the switch mechanism 20 by pressing the button member 30.

[0096] It should be noted that the structure of the slot 101 and the through hole 102 in this embodiment is basically the same as that in the previous embodiment. Since the blocking member 40 in this embodiment is rotatably engaged with the housing 10, the through hole 102 needs to provide a certain amount of space for the rotational movement of the blocking member 40.

[0097] In this embodiment, the blocking member 40 is provided with a lifting rod 48 that passes through the through hole 102 and extends into the slot 101, so that when the start key 50 is inserted into the slot 101, it can push the lifting rod 48 so that the lifting rod 48 drives the blocking member 40 to rotate around the pivot 47.

[0098] In this embodiment, the through hole 102 is constructed as a fan-shaped hole to provide the space required for the rotation of the lifting rod 48. In order to make the through hole 102 have better sealing performance, a deformable elastic water-blocking member can be provided between the inner wall of the through hole 102 and the lifting rod 48.

[0099] The specific structure of the blocking member 40 in another embodiment of this invention will be described below.

[0100] In one embodiment of this implementation, please refer to Figures 33 to 36 The direction in which the button component 30 moves relative to the housing 10 is defined as the first direction. The blocking component 40 is rotatably connected to the housing 10 about a second axis, which is parallel to the first direction. This arrangement allows the blocking component 40 to rotate about the second axis to either be on or off the trigger path of the button component 30.

[0101] In one embodiment of this implementation, please refer to Figures 33 to 36The housing 10 has a slot 101, and a through hole 102 is formed on the side wall of the slot 101. One end of the blocking member 40 extends into the slot 101 through the through hole 102. When the start key 50 is inserted into the slot 101, it can be circumferentially fixedly engaged with the blocking member 40. Furthermore, the start key 50 can rotate around a second axis within the slot 101 to rotate the blocking member 40 from a first position to a second position. It is understood that in this embodiment, the user needs to first insert the start key 50 into the slot 101, fixing the start key 50 and the blocking member 40 circumferentially. Then, the user rotates the start key 50, causing the blocking member 40 and the start key 50 to rotate synchronously around the second axis, thereby rotating the blocking member 40 from the first position to the second position. This requires the start key 50 to be inserted first and then rotated twice to move the blocking member 40, making it less likely for the user to misoperate and effectively improving safety.

[0102] It should be noted that the structure of the slot 101 and the through hole 102 in this embodiment is basically the same as that in the previous embodiment. Since the blocking member 40 in this embodiment is rotatably engaged with the housing 10, the through hole 102 needs to provide a certain amount of space for the rotational movement of the blocking member 40.

[0103] In this embodiment, one end of the blocking member 40 passes through the perforation and extends into the slot 101. The end is provided with a connection hole 405. The shape of the connection hole 405 matches the start key 50. When the start key 50 is inserted into the slot 101, the start key 50 can be inserted into the connection hole 405 to be circumferentially fixedly connected with the blocking member 40.

[0104] In this embodiment, the axis of the start key 50 is the second axis.

[0105] In this embodiment, the through hole 102 is constructed as a fan-shaped hole to provide the space required for the rotation of the end of the blocking member 40. In order to make the through hole 102 have better sealing performance, a deformable elastic water-blocking member can be provided between the inner wall of the through hole 102 and the lifting rod 48.

[0106] The connection method between the button component 30 and the housing 10 in one embodiment of this invention will be described below.

[0107] In one embodiment of this implementation, please refer to Figure 3 , Figure 18 and Figure 29 A second elastic member 31 is provided between the button component 30 and the housing 10. The second elastic member 31 applies an elastic force to the button component 30 to move it from the start position to the stop position. This arrangement is so that after the blocking member 40 leaves the trigger path, the button component 30 can return to the stop position under the action of the second elastic member 31 to stop triggering the switch mechanism 20.

[0108] In this embodiment, the middle shell 12 of the housing 10 is provided with a second sliding groove 107. Part of the button component 30 is rod-shaped and slides in cooperation with the second sliding groove 107. The second elastic element 31 is a spring, which is located in the second sliding groove 107. One end of the spring abuts against the bottom side of the button component 30, and the other end abuts against the bottom wall of the second sliding groove 107.

[0109] The following describes the self-locking mechanism and blocking method between the button component 30 and the blocking component 40 in one embodiment of this invention.

[0110] In one embodiment of this implementation, please refer to Figures 19 to 24 The multi-signal start type safety lock 100 includes a self-locking component 60, which is disposed on the blocking component 40. The button component 30 has a guide groove 301 and a lock cylinder 32 located in the guide groove 301.

[0111] When the blocking member 40 is in the second position, the self-locking member 60 extends into the guide groove 301 and is located on the bottom side of the lock cylinder 32.

[0112] When the button component 30 moves along the trigger path, the self-locking component 60 can move along the side 321 of the lock cylinder 32 and the groove wall 3011 of the guide groove 301 to the top side of the lock cylinder 32, and can abut against the lock cylinder 32 under the action of the second elastic member 31, so that the button component 30 is kept in the start position.

[0113] As the button component 30 continues to move along the trigger path, the self-locking component 60 can leave the lock cylinder 32 and move along the groove wall 3011 of the guide groove 301 to be offset from the lock cylinder 32, so that the button component 30 can return to the stop position under the action of the second elastic member 31.

[0114] Understandably, after the user inserts the start key 50, the blocking member 40 is in the second position, and the self-locking member 60 extends into the guide groove 301. Then, the user presses the button member 30. Since the blocking member 40 is not on the trigger path, the button member 30 can move smoothly from the stop position to the start position. At this time, the relative position of the blocking member 40 and the button member 30 changes, and the self-locking member 60 also moves in the guide groove 301. The self-locking member 60 first abuts against the side 321 of the bottom side of the lock cylinder 32, and slides along the side 321 to abut against the groove wall 3011 of the guide groove 301, so as to move to the top side of the lock cylinder 32. This allows the self-locking member 60 to abut against the top side of the lock cylinder 32 after the user releases the button member 30, thus preventing the button member 30 from returning to the stop position. The button member 30 can continuously trigger the switch mechanism 20. When the user needs to deactivate the switch mechanism 20, the user can press the button component 30 again. The self-locking component 60 moves upward relative to the lock cylinder 32 to disengage from the lock cylinder 32 and slides along the groove wall 3011 of the guide groove 301 until it is offset from the lock cylinder 32. This allows the button component 30 to no longer be restricted by the self-locking component 60, and the button component 30 can return to the stop position under the action of the second elastic member 31. Therefore, the self-locking component 60 allows the user to easily activate the switch by pressing it, maintain the activation after releasing it, and deactivate it by pressing it again.

[0115] In this embodiment, when the blocking member 40 is in the first position, the self-locking member 60 is located outside the guide groove 301. Figure 6 During the insertion of the start key 50 into the slot 101, the blocking member 40 moves from the first position to the second position, and the self-locking member 60 extends into the guide groove 301 (Figure 10).

[0116] In another embodiment, when the blocking member 40 is in the first position, the self-locking member 60 is located outside the guide groove 301. Figure 30 During the insertion of the start key 50 into the slot 101, the blocking member 40 rotates from the first position to the second position around the first axis, and the self-locking member 60 extends into the guide groove 301. Figure 31 ).

[0117] In another embodiment, when the blocking member 40 is in the first position, the self-locking member 60 is located outside the guide groove 301. Figure 34 As the start key 50 is inserted into the slot 101 and rotates within it, the blocking member 40 rotates from the first position to the second position about the second axis, and the self-locking member 60 extends into the guide groove 301. Figure 35 ).

[0118] In this embodiment, the side surface 321 of the lock cylinder 32 and the groove wall 3011 of the guide groove 301 have a certain guiding function, which enables the self-locking member 60 to move from the bottom side to the top side of the lock cylinder 32 during the pressing process of the button member 30.

[0119] In one embodiment of this implementation, please refer to Figures 19 to 24 The lock cylinder 32 has a limiting groove 3201. Under the action of the second elastic member 31, the self-locking member 60 can abut against the bottom wall of the limiting groove 3201. It can be understood that the limiting groove 3201 can restrict the self-locking member 60 from leaving the lock cylinder 32, so that the button member 30 can be well held in the start position before the user presses the button member 30 again.

[0120] Specifically, the limiting groove 3201 is a V-shaped groove so that the self-locking member 60 can enter or leave the limiting groove 3201.

[0121] In one embodiment of this implementation, please refer to Figures 19 to 24 The guide groove 301 has a transition groove 3012 on its groove wall 3011, which is opposite to the limiting groove 3201. With this configuration, when the user presses the button component 30, the self-locking component 60 can slide into the transition groove 3012 along the groove wall 3011 of the guide groove 301, so as to ensure that after the user releases the button component 30, the self-locking component 60 can accurately enter the limiting groove 3201, which has high reliability.

[0122] In this embodiment, the guide groove 3011 has a return groove 3014 offset from the lock cylinder 32. The return groove 3014 is adjacent to the transition groove 3012, and an inclined wall 3015 is provided between the return groove 3014 and the transition groove 3012. The inclined wall 3015 is disposed opposite to the limiting groove 3201. It can be understood that the transition groove 3012 is provided to allow the self-locking member 60 to enter the limiting groove 3201 better, while the return groove 3014 is provided to allow the self-locking member 60 to extend into the return groove 3014 after leaving the limiting groove 3201, thereby achieving offset from the lock cylinder 32. The inclined wall 3015 is provided to allow the self-locking member 60 to slide along the inclined wall 3015 to enter the return groove 3014 after leaving the limiting groove 3201.

[0123] In one embodiment of this implementation, please refer to Figures 19 to 24The self-locking member 60 includes a locking rod 61 and a third elastic member 62. The locking rod 61 is pivotally mounted on the blocking member 40. The third elastic member 62 is connected to the locking rod 61 and applies an elastic force to the locking rod 61, enabling it to return to a position opposite to the top or bottom side of the lock cylinder 32. It is understood that the locking rod 61 can pivot relative to the blocking member 40 so that it can be aligned with or offset from the lock cylinder 32, thereby achieving self-locking and unlocking. Furthermore, under the action of the third elastic member 62, the locking rod 61 can return to a position opposite to the lock cylinder 32, so that during both self-locking and unlocking processes, the locking rod 61 can move unidirectionally along the side 321 of the lock cylinder 32.

[0124] In this embodiment, to further ensure that the locking lever 61 can move unidirectionally along the side 321 of the lock cylinder 32, the bottom side 321 of the lock cylinder 32 is inclined relative to the movement direction of the button component 30, so that the locking lever 61 can stably slide to the right side of the lock cylinder 32 under the action of the bottom side 321 of the lock cylinder 32. It can be understood that during the self-locking and unlocking process, the locking lever 61 always moves around the lock cylinder 32 in a fixed clockwise direction.

[0125] In one embodiment of this implementation, please refer to Figures 19 to 24 The self-locking member 60 includes a lock cover 63, and the blocking member 40 has a mounting groove 401. The lock cover 63 covers the opening of the mounting groove 401 and defines a clearance hole 402 for the locking rod 61 to swing. One end of the locking rod 61 is rotatably clamped between the lock cover 63 and the bottom wall of the mounting groove 401, and the other end of the locking rod 61 extends from the clearance hole 402 and is used to extend into the guide groove 301. This arrangement allows the locking rod 61 to swing relative to the blocking member 40 to a certain extent.

[0126] In this embodiment, the third elastic element 62 is constructed as a spring, which is disposed within the mounting groove 401. One end of the spring abuts against the lock cover 63, and the other end of the spring is connected to the lock rod 61. Optionally, the spring can be connected to the lock rod 61 by means of adhesive bonding, welding, or other methods to achieve the elastic force required for the lock rod 61 to reset.

[0127] In this embodiment, the locking rod 61 includes a first rod 611, a second rod 612, and a third rod 613 connected in sequence. The first rod 611 abuts against the bottom wall of the mounting groove 401 and can swing around its own axis. One end of the second rod 612 is connected to the first rod 611, and the other end of the second rod 612 extends to the through-hole 402 and is connected to the third rod 613. The third rod 613 is used to extend into the guide groove 301. Specifically, the first rod 611 and the second rod 612 form an angle, and the third rod 613 and the second rod 612 form an angle. The extension direction of the first rod 611 relative to the second rod 612 is opposite to the extension direction of the third rod 613 relative to the second rod 612.

[0128] It should be noted that the first rod 611 has a degree of freedom to rotate around its own axis by a certain angle within the mounting groove 401, so as to drive the third rod 613 to move around the lock cylinder 32 in a fixed clockwise direction. Furthermore, the first rod 611 has a degree of freedom to swing a certain amplitude within the mounting groove 401 in the deformation direction of the third elastic member 62, so that under the elastic action of the third elastic member 62, the third rod 613 can press against the bottom wall of the limiting groove 3201, achieving self-locking. Figure 21 At this point, one end of the first rod 611 connected to the second rod 612 is suspended relative to the bottom wall of the mounting groove 401. When the third rod 613 leaves the limiting groove 3201, under the elastic action of the third elastic element 62, the end of the first rod 611 connected to the second rod 612 can slide down along the inner wall of the mounting groove 401 again and re-fit against the bottom wall of the mounting groove 401, thereby driving the third rod 613 back to its initial position. Figure 20 ).

[0129] In another embodiment, please refer to Figures 33 to 36 The mounting groove 401 has an opening 3013 on one side. When the start key 50 drives the blocking member 40 to rotate around the second axis, the locking rod 61 on the self-locking member 60 can extend into the mounting groove 401 through the opening 3013.

[0130] In one embodiment of this implementation, please refer to Figure 23 The blocking member 40 includes an actuating rod 42, a blocking block 43, a connecting rod 44, and a lock housing 45. One end of the actuating rod 42 is slidably engaged with the middle housing 12, and the other end of the actuating rod 42 extends into the slot 101 for actuation by the start key 50. The blocking block 43 is connected to one side of the actuating rod 42 and has a blocking surface 403 for blocking the button member 30. One end of the connecting rod 44 is connected to the blocking block 43, and the other end of the connecting rod 44 is connected to the lock housing 45. A mounting groove 401 is formed on the top side of the lock housing 45, and a clearance area 404 for the button member 30 to pass through is formed between the lock housing 45 and the blocking block 43.

[0131] It should be noted that in some embodiments, the self-locking member 60 can be omitted, so that the button member 30 can be directly reset to the stop position under the elastic action of the second elastic member 31 after being pressed, instead of remaining in the start position.

[0132] The following provides a supplementary description of the switching mechanism 20 in one embodiment of this invention.

[0133] In one embodiment of this implementation, please refer to Figure 25 and Figure 26The switching mechanism 20 includes a circuit board 21 and an indicator switch 24. The circuit board 21 is used for electrical connection with electrical equipment. The indicator switch 24 is disposed on the circuit board 21 and is electrically connected to the indicator light 151. When the blocking member 40 is in the second position, the blocking member 40 closes the indicator switch 24. This configuration ensures that before the start key 50 is inserted, the blocking member 40 is in the first position, and the indicator switch 24 has not yet been triggered, so the indicator light 151 remains off to save power. After the start key 50 is inserted, the blocking member 40 moves from the first position to the second position and triggers the indicator switch 24, illuminating the indicator light 151 for operation.

[0134] In one embodiment of this implementation, to facilitate the triggering of the blocking member 40, the indicator switch 24 is a micro switch, a spring contact switch, or a tactile switch. For details, please refer to [link to relevant documentation]. Figure 25 and Figure 26 The indicator switch 24 is a micro switch, and the connecting rod 44 in the blocking member 40 can trigger the micro switch. Please refer to [link / reference]. Figure 27 and Figure 28 The indicator switch 24 is a reed switch, and the connecting rod 44 in the blocking member 40 can trigger the reed switch.

[0135] In one embodiment of this implementation, please refer to Figure 15 , Figures 37 to 39 The indicator light 151 is mounted on the circuit board 21, and light is transmitted to the housing 10 through the light guide structure 152. This arrangement allows the user to observe the illumination status of the indicator light 151 through the housing 10, facilitating user operation.

[0136] In this embodiment, the light guide structure 152 includes a light guide plate 1520 and a light guide foot 1521. The light guide plate 1520 is opposite to the soft elastic layer 113 in the upper shell 11 and has a gap between them. One end of the light guide foot 1521 is connected to the light guide plate 1520, and the other end is mounted on the middle shell 12 and opposite to the indicator light 151. With this arrangement, the light emitted by the indicator light 151 can be transmitted to the light guide plate 1520 through the light guide foot 1521, allowing the user to observe the light emission of the light guide plate 1520 through the soft elastic layer 113. The gap between the light guide plate 1520 and the soft elastic layer 113 provides space for the rigid button block 112 to move.

[0137] In this embodiment, there are two light guide feet 1521 and two indicator lights 151, with each light guide foot 1521 corresponding to a corresponding indicator light 151. This arrangement allows the two indicator lights 151 to transmit light to the light guide plate 1520 via their respective light guide feet 1521. Furthermore, the two light guide feet 1521 ensure that the light guide structure 152 is securely mounted on the middle shell 12 of the housing 10.

[0138] In this embodiment, the light guide foot 1521 is provided with a positioning hole 1522, and the middle shell 12 is provided with a positioning post 121. The positioning post 121 cooperates with the positioning hole 1522 to realize the positioning and installation of the light guide structure 152.

[0139] In this embodiment, the light guide plate 1520 is constructed in a ring shape corresponding to the soft elastic layer 113, so that the light emitted by the light guide plate 1520 is of higher intensity and can be concentrated to pass through the soft elastic layer 113.

[0140] In one embodiment of this implementation, please refer to Figure 15 , Figures 40 to 42 The housing 10 contains a mounting bracket 14, on which a control board 15 electrically connected to the circuit board 21 is mounted. An indicator light 151 is mounted on the control board 15. This arrangement reduces the distance between the indicator light 151 and the housing 10, improving light transmission efficiency, and allowing the user to better observe the illumination of the indicator light 151 from the housing 10.

[0141] In this embodiment, the mounting bracket 14 is mounted on the middle shell 12 of the housing 10, and the control board 15 is mounted on the top side of the mounting bracket 14 and electrically connected to the circuit board 21 via the connecting device 16. The control board 15 is spaced apart from the soft elastic layer 113 in the upper shell 11, which provides some space for the rigid button block 112 in the upper shell 11 and allows the indicator light 151 on the control board 15 to shine light onto the soft elastic layer 113. The indicator switch 24 is used to activate the relevant circuits on the control board 15.

[0142] In this embodiment, in order to install the mounting bracket 14 on the housing 10, the mounting bracket 14 includes a mounting plate 141 and a mounting leg 142 connected to each other. The mounting leg 142 is used to install on the middle shell of the housing 10, and the top side of the mounting plate 141 is used to install the control plate 15.

[0143] In this embodiment, in order to achieve the positioning of the mounting bracket 14 and the housing 10, the mounting leg 142 is provided with an assembly hole 1421, and the middle shell 12 of the housing 10 is provided with a positioning post 121, which cooperates with the assembly hole 1421.

[0144] In this embodiment, in order to reduce the space occupied by the mounting plate 141 and the control plate 15 in the housing 10, a receiving groove 1411 is provided on the top side of the mounting plate 141, and the control plate 15 is fixed in the receiving groove 1411.

[0145] In this embodiment, in order to realize the installation of the control board 15 and the mounting plate 141, the bottom wall of the receiving groove 1411 is provided with a buckle 1412, and the outer periphery of the control board 15 is provided with a buckle groove 153, and the buckle 1412 and the buckle groove 153 cooperate.

[0146] In this embodiment, in order to improve the reliability of the installation of the control board 15 and the mounting plate 141, there are multiple buckles 1412 and buckle slots 153, and they are matched one by one.

[0147] The mechanical safety lock provided by this utility model has basic safety lock functions (can resist accidental contact with external force ≥120N), and due to the presence of the sealing structure (first sealing ring 103, second sealing ring 105, and ring rib 131), it has good waterproof and dustproof performance. It can pass the IPx7 test and resist 10KPa water pressure for 30 minutes without penetration, thus improving operational safety and environmental adaptability.

[0148] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
