Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6This utility model provides a technical solution: a self-locking safety switch to prevent accidental touch, including a housing mechanism 1. The main body of the housing mechanism 1 is a box structure with a one-way opening at the front end. A storage battery 3 is fixedly connected inside the housing mechanism 1. A control module 301 is fixedly connected to the top surface of the storage battery 3. A charging component 3011 is fixedly connected to the rear side of the storage battery 3. The charging component 3011 extends out of the housing mechanism 1 to the rear side.

[0026] The housing mechanism 1 is internally connected to a rotating shaft assembly 3012. Two rotating shaft assemblies 3012 are provided, arranged in a linear array on the upper and lower sides inside the housing mechanism 1. A drive gear 3013 and a driven gear 3014 are respectively mounted on the outer sides of the two rotating shaft assemblies 3012, meshing and transmitting power. Two spring members 3015 are fixedly connected in a linear array on the right end face inside the housing mechanism 1. On the left side of 015, a locking tongue assembly 3016 is fixedly connected. The locking tongue assembly 3016 extends to the left side of the housing mechanism 1. The inner side of the two locking tongue assemblies 3016 is fixedly connected to a horizontally arranged toothed row assembly 3017. The inner side of the housing mechanism 1 is fixedly connected to a servo push rod 3018. There are two servo push rods 3018. The two servo push rods 3018 are fixedly connected to the inner side of the housing mechanism 1 in opposite directions. The inner side of the two servo push rods 3018 is fixedly connected to a locking block assembly 3019.

[0027] By setting up a storage battery 3, a control module 301, and a charging component 3011 inside the housing mechanism 1, the switch is provided with electrical energy and control functions and is convenient for charging; two rotating shaft assemblies 3012, a drive gear 3013, and a driven gear 3014 are set up to realize transmission; a mechanical self-locking and control structure is constructed by setting up a spring component 3015, a locking tongue assembly 3016, a gear rack assembly 3017, a servo push rod 3018, and a locking block assembly 3019, so as to realize the control and locking of the locking tongue assembly 3016.

[0028] See Figure 1 , Figure 5 A mounting plate 101 is fixedly connected to the outside of the housing mechanism 1. The main body of the mounting plate 101 is a rectangular frame structure.

[0029] By connecting the mounting plate 101 of the rectangular frame structure to the outside of the housing mechanism 1, a mounting carrier is provided for the safety switch, which facilitates the installation of the switch on other equipment or locations and enhances the ease of installation of the switch.

[0030] See Figure 2 , Figure 3 The mounting plate 101 has a through hole inside, which is a mounting hole 1011. There are four mounting holes 1011 in total, and the four mounting holes 1011 are respectively opened at the four corners inside the mounting plate 101.

[0031] By opening four mounting holes 1011 at the four corners inside the mounting plate 101, which can be used to cooperate with the fixing bolts 1012, the installation position is precisely defined, making the switch installation more stable and standardized, and ensuring the accuracy and stability of the installation.

[0032] See Figure 5 , Figure 6 Each of the four mounting holes 1011 is fitted with a fixing bolt 1012, and each of the four corners of the housing mechanism 1 is provided with a bidirectional through insertion hole 1013 on both the front and rear sides.

[0033] By providing bidirectional through-holes 1013 at the four corners inside the housing mechanism 1, the installation method is further standardized, ensuring the reliable installation of the fixing bolt 1012. At the same time, the through-holes 1013 can be used for other connections or positioning, enhancing the stability and versatility of the installation.

[0034] See Figure 1 , Figure 2 A front panel 2 is installed at the front end of the housing mechanism 1, and a plug rod 201 is fixedly connected to the rear side of the front panel 2.

[0035] By installing a front panel 2 at the front end of the housing mechanism 1 and connecting a plug rod 201 to the rear side of the front panel 2, the front panel 2 serves as a protective and decorative element, while the plug rod 201 provides a positioning and connection method for the installation of the front panel 2, facilitating the installation and fixation of the front panel 2.

[0036] See Figure 3 , Figure 4 The main body of the insertion rod 201 is a cylindrical structure. There are four insertion rods 201 in total, and the four insertion rods 201 are fixedly connected to the four corners of the rear end face of the front panel 2.

[0037] By designing the insert rod 201 as a cylindrical structure and placing one at each of the four corners of the rear end face of the front panel 2, the cylindrical structure facilitates installation and positioning, and the four insert rods 201 can be evenly stressed, making the installation of the front panel 2 more stable and reliable.

[0038] See Figure 1 , Figure 2 Nuts 2011 are screwed onto the outer side of the four insertion rods 201. A knob 2012 is installed at the front end of the front panel 2. The knob 2012 is sleeved with the rotating shaft assembly 3012 located on the upper side. A fingerprint module 2013 that is electrically connected to the control module 301 is fixedly connected to the front end of the knob 2012.

[0039] The front panel 2 can be further secured by screwing a nut 2011 onto the outside of the plug 201; a knob 2012 is installed at the front end of the front panel 2 and is sleeved with the upper rotating shaft assembly 3012, and the knob 2012 can be operated manually; a fingerprint module 2013 electrically connected to the control module 301 is connected to the front end of the knob 2012 to realize the fingerprint recognition control function, which increases the security and convenience of the switch operation.

[0040] During operation and use, first install the safety switch onto the target device through the mounting holes 1011 and fixing bolts 1012 on the mounting plate 101, and then tighten the fixing bolts 1012 through the mounting holes 1011 and the corresponding threaded holes on the device. If necessary, additional positioning or connection operations can be performed using the insertion holes 1013 at the four corners inside the housing mechanism 1 to enhance the stability of the installation.

[0041] The charging component 3011 is connected to an external power source to charge the battery 3, so that the battery 3 provides stable power support for the entire safety switch. After power-on, the control module 301 is initialized to receive and process various signals.

[0042] When it is necessary to open the cabinet door or other device corresponding to the safety switch, the user places his finger on the fingerprint module 2013. The fingerprint module 2013 collects fingerprint information and transmits it to the control module 301. The control module 301 compares the collected fingerprint information with the pre-stored fingerprint data. If the comparison is successful, the control module 301 sends a signal to the servo push rod 3018.

[0043] After receiving the signal from the control module 301, the two servo push rods 3018 move simultaneously and extend outward. The locking block assembly 3019 fixed inside the servo push rod 3018 moves as the servo push rod 3018 extends, disengaging from the gear engagement state. At this time, continue to rotate the knob 2012, indirectly driving the two locking tongue assemblies 3016 to retract into the housing mechanism 1, no longer locking the cabinet door and other devices.

[0044] When the cabinet door needs to be closed, manually push the cabinet door to compress the latch assembly 3016, which moves inward against the elastic force of the spring 3015. At this time, the toothed assembly 3017 moves together with the latch assembly 3016. After the cabinet door is completely closed, the latch assembly 3016 extends again under the action of the spring 3015, completing the initial locking of the cabinet door. At the same time, the control module 301 controls the servo push rod 3018 to retract, so that the locking block assembly 3019 re-engages with the toothed assembly 3017, realizing mechanical self-locking and preventing the cabinet door from being accidentally opened due to accidental contact.

[0045] In summary, this device, by setting up the control module 301, can identify the operator's fingerprint.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
