[0052] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0053] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0056] In the actual operation of power distribution network equipment, locks are an important component of security management, and their performance directly affects operational efficiency and security. Currently, smart locks are improvements on traditional mechanical locks; however, power distribution networks all use individual electronic lock cylinders. When the electronic lock cylinder malfunctions, the lock can often only be opened by force, which not only affects operational efficiency but may also damage the equipment and increase maintenance costs.

[0057] To address the aforementioned issues, this application provides a door lock device for power distribution networks. By setting up a main lock cylinder and an emergency lock cylinder that do not interfere with each other, both can be operated independently to open and close the lock. When the main lock cylinder malfunctions and cannot be opened, the lock can be opened through the emergency lock cylinder, reducing the risk of lock failure and improving operational efficiency.

[0058] The following will combine Figures 1 to 10 The specific structure of the door lock device provided in the embodiments of this application will be described. (Refer to...) Figures 1 to 4 As shown, the door lock device provided in this embodiment is mainly used in power distribution networks.

[0059] Reference Figure 5 and Figure 6 As shown, the door lock device 100 includes a lock housing 110, which has a mounting cavity 111. The mounting cavity 111 is provided with a main lock cylinder 120, an emergency lock cylinder, a bolt 140, a drive component 150, and a sliding component 160. A lock beam 170 is connected to the lock housing 110, and the emergency lock cylinder is electrically connected to the drive component 150.

[0060] For example, the drive element 150 can be a motor, and the slider 160 can be a slide bar.

[0061] For example, refer to Figure 5 and Figure 6 As shown, the lock housing 110 may include a lock body 113 and a rear cover 112. The rear cover 112 covers the lock body 113 and forms an installation cavity 111 with the lock body 113. The lock body 113 and the rear cover 112 may be connected by screws.

[0062] For example, refer to Figure 5 As shown, it may also include a motor mounting base 153 and a motor cover 154. The motor is mounted in the motor mounting base 153, and the motor cover 154 covers the opening of the motor mounting base 153 to seal the motor.

[0063] For example, the structure and connection method of the emergency lock cylinder are not limited. For instance, if the emergency lock cylinder is an electronic lock cylinder with chip identification function, its signal line can be soldered or plugged into the controller on circuit board 131 to ensure stable signal transmission; or, the emergency lock cylinder can be connected to the front end of the motor shaft through the keyhole, and the motor shaft can be directly driven to rotate after the key is inserted. In this embodiment, the emergency lock cylinder is mainly described as an electronic lock cylinder.

[0064] In this embodiment, the first end 161 of the slider is connected to the pin 140, the second end 162 of the slider abuts against the main lock cylinder 120, and the pin 140 is connected to the drive shaft 151 of the drive member 150.

[0065] The connection method between the slider 160 and the pin 140 is not limited. For example, the slider 160 and the pin 140 can be directly fixed with bolts or screws to ensure synchronous movement without relative displacement. Alternatively, the slider 160 and the pin 140 can be connected by a snap-fit ​​or elastic structure. In this embodiment, the first end 161 of the slider is snapped onto the pin 140 to drive the pin 140 to move. This ensures synchronous movement and also facilitates the disassembly or replacement of the slider and the pin 140.

[0066] The connection method between the pin 140 and the drive shaft 151 is not limited. The pin 140 has a recessed hole, and the drive shaft 151 passes through the recessed hole and connects to the pin 140. This allows the drive shaft 151 to move the pin 140 during rotation.

[0067] The working principle of the main lock cylinder 120 is as follows: when a key is inserted and the main lock cylinder 120 is rotated, the main lock cylinder 120 pushes the sliding member 160 to slide, which in turn pushes the bolt 140 to move along the drive shaft 151, causing the bolt 140 to disengage from the lock beam 170 (unlocking) or engage (locking). The working principle of the emergency lock cylinder is as follows: when the main lock cylinder 120 fails, the emergency lock cylinder is triggered when a key is inserted into it. This triggers the drive member 150 to rotate via an electrical connection, which in turn moves the bolt 140, thus unlocking or locking.

[0068] In this embodiment, whether unlocking or locking is achieved through the main lock cylinder 120 or the emergency lock cylinder, the movement path of the bolt 140 and the interface of the lock beam 170 are consistent. This helps ensure that the unlocking / locking logic is unified in both modes, improving operational compatibility; at the same time, the unified movement path reduces potential action conflicts that may occur when the two lock cylinders are driven independently, improving operational security.

[0069] It should be noted that the principle of the motor rotating to move the latch 140 is as follows: For example, in an emergency unlocking scenario (motor rotating forward), specifically, after inserting the key, the motor rotates clockwise, the motor shaft moves forward, and the rotational motion is converted into axial thrust. This thrust acts directly on the latch 140. Under the action of the thrust, the latch 140 slides to the left along the drive shaft 151, disengaging from the insertion slot 172 of the lock beam 170. The lock beam 170 then springs off the lock housing 110, completing the unlocking process. In an emergency locking scenario (motor rotating in reverse), specifically, after inserting the key, the motor rotates counterclockwise, the motor shaft rotates in the opposite direction, and pushes the latch 140 to slide to the right. The latch 140 engages with the insertion slot 172 of the lock beam 170. Manually pressing down the lock beam 170 aligns the insertion slot 172 of the lock beam 170 with the latch 140, and the latch 140 re-enters the insertion slot 172, completing the locking process.

[0070] The drive shaft 151 is fitted with a pin 140, and the axes of the two coincide, which helps to ensure that the axial force of the motor shaft acts directly on the pin 140, reducing radial force loss or jamming.

[0071] Therefore, in this embodiment, by setting up a main lock cylinder 120 and an emergency lock cylinder that do not interfere with each other, both can be operated independently to open and close the lock. When the main lock cylinder 120 malfunctions and cannot be opened, it can be unlocked through the emergency lock cylinder, reducing the risk of lock failure and improving work efficiency. By setting up a sliding member 160, which moves linearly in a fixed direction (such as the horizontal direction), the rotational motion of the main lock cylinder 120 (key rotation) can be accurately converted into the axial displacement of the pin 140, reducing the backlash error of traditional gear transmission or the slippage problem of belt transmission. Moreover, the sliding member 160 directly connects the main lock cylinder 120 (through the lever 123) and the pin 140, eliminating the need for additional gears, chains, or other transmission components, thus simplifying the internal structure of the lock.

[0072] In some embodiments, reference is made to Figure 7 As shown, the main lock cylinder 120 is configured to rotate when a key is inserted, and push the slider 160 to move in a first direction. The slider 160 drives the bolt 140 to move in the first direction, and the bolt 140 disengages from the lock beam 170.

[0073] Alternatively, when the main lock cylinder 120 fails, the emergency lock cylinder is configured to rotate the drive component 150 when the key is inserted, and the drive component 150 drives the bolt 140 to move in the first direction, so that the bolt 140 disengages from the lock beam 170.

[0074] For example, the first direction can be to move to the left, as can be seen in the following example. Figure 7 The direction indicated by the middle arrow A1.

[0075] It should be noted that regardless of whether the main lock cylinder 120 or the emergency lock cylinder is used, the bolt 140 moves in the same direction to unlock the lock. Operators do not need to memorize the operating directions for different modes, reducing the probability of operational errors. Moreover, since the bolt 140 moves along the same trajectory in both modes, it is unnecessary to design a separate transmission structure for the emergency lock cylinder, reducing the number of parts, assembly complexity, and potential points of failure.

[0076] Specifically, the normal unlocking mode of the main lock cylinder 120 is a mechanical transmission path. Inserting the key into the main lock cylinder 120 and turning it clockwise drives the main lock cylinder 120 to rotate. The main lock cylinder 120 then pushes the sliding member 160 to move in a first direction (e.g., to the left) via the lever 123. The sliding member 160 simultaneously moves the bolt 140 to the left, causing the bolt 140 to disengage from the insertion slot 172 of the lock beam 170. The lock beam 170 then pops out under the action of a spring, completing the unlocking process. It can be understood that its core logic achieves unlocking through a purely mechanical transmission chain, requiring no electrical support.

[0077] Specifically, the emergency lock cylinder unlocking mode uses a hybrid electromechanical transmission path. When the emergency lock cylinder key is inserted, the key drives the motor to rotate clockwise. The motor shaft applies axial thrust to the pin 140 via a spring. The pin 140 disengages from the insertion slot 172 of the lock beam 170 in the first direction (leftward movement), and the lock beam 170 springs up, thus achieving emergency unlocking. Its core logic is to bypass the mechanical structure of the main lock cylinder 120 and forcibly move the pin 140 through an electronically controlled path driven by a motor and driven by a spring.

[0078] In some embodiments, reference is made to Figure 8 As shown, the main lock cylinder 120 is configured to rotate in the opposite direction when a key is inserted, and push the sliding member 160 to move in the second direction. The sliding member 160 drives the bolt 140 to move in the second direction, and the bolt 140 is engaged with the lock beam 170.

[0079] Or, refer to Figure 9 As shown, when the main lock cylinder 120 fails, the emergency lock cylinder is configured to rotate in the opposite direction when the key is inserted, and drive the drive component 150 to rotate in the opposite direction. The drive component 150 drives the bolt 140 to move in the second direction, and the bolt 140 is engaged with the lock beam 170.

[0080] The first direction and the second direction are two opposite directions in which the pin 140 moves relative to the locking beam 170.

[0081] For example, the second direction can be moving to the right, as can be seen in the following example. Figure 8 and Figure 9 The direction indicated by the middle arrow A2.

[0082] With the above settings, the locking and unlocking actions correspond in opposite directions. That is, when unlocking, the pin 140 disengages from the lock beam 170 along the first direction (leftward movement), and when locking, it is inserted along the second direction (rightward movement). The directions are completely opposite and unique. Operators can quickly operate through simple logic, reducing locking failures caused by confusion of directions.

[0083] In some embodiments, reference is made to 7 to Figure 9 As shown, along the height direction of the lock housing 110, the slider 160 is located above the drive member 150 and the latch 140. (Refer to...) Figure 6 As shown, a support base 180 can be provided in the mounting cavity 111. A slide rail 181 is provided on the support base 180. A sliding member 160 is provided on the support base 180 and moves relative to the slide rail 181.

[0084] In this embodiment, by positioning the slider 160 above the lock housing 110 in the height direction, and the drive unit 150 and the latch 140 below, a layered transmission structure is formed. This physically isolates the two components in the height direction, reducing mutual contact during transmission. For example, when the main lock cylinder 120 drives the slider 160 to move to the left, it will not interfere with the lower motor shaft or spring, ensuring that the two lock cylinders operate independently.

[0085] Furthermore, the layered layout creates an air convection space between the slider 160 and the drive component 150, allowing the heat generated by the motor to be dissipated through the heat dissipation holes on the top of the lock housing 110, thus preventing the electronic components (such as the circuit board 131) from aging faster due to heat accumulation.

[0086] In this embodiment, a support base 180 is provided to support the sliding member 160, ensuring its stable movement trajectory. A slide rail 181 is provided on the slide rail for the sliding member 160 to slide. The bottom of the sliding member 160 is embedded in the slide rail 181, allowing it to reciprocate only along the axial direction (horizontal direction) of the pin 140, thus limiting the displacement in the vertical direction (height direction). At the same time, when the sliding member 160 moves within the slide rail 181, the two side walls provide radial constraints, ensuring its precise movement along the axial direction of the pin 140, and preventing the sliding member 160 from tilting or getting stuck due to uneven thrust of the main lock cylinder 120.

[0087] In some embodiments, reference is made to Figure 5 As shown, the slider 160 can be a frame structure. In the horizontal direction, the slider 160 surrounds the outer periphery of the drive member 150 and the pin 140, and exposes the drive member 150 and the pin 140.

[0088] For example, the slider 160 is frame-shaped (such as a rectangular frame or a U-shaped frame) and surrounds the drive member 150 (motor) and the outer periphery of the pin 140 in the horizontal direction (axial direction of the pin 140) to form a "hollow" transmission structure. For example, the left and right side walls of the frame-shaped slider 160 are located on the outside of the pin 140 and the motor, respectively, the bottom opening exposes the drive member 150 and the pin 140, and the top is linked to the main lock cylinder 120 through the extension edge 163.

[0089] In this way, the hollow design of the frame structure exposes the drive component 150 and the pin 140, ensuring that the motor shaft, spring and other components of the emergency lock cylinder can be directly connected to the pin 140 (such as the motor shaft extending from the bottom of the frame). At the same time, the paddle 123 of the main lock cylinder 120 drives the sliding component 160 through the extension edge 163. The two do not obstruct each other in space, and the transmission path is independent and clear. Moreover, the frame structure exposes the drive component 150 and the pin 140, so maintenance personnel can directly observe the rotation of the motor shaft and the insertion status of the pin 140 and the lock beam 170 without disassembling the lock housing 110.

[0090] In this embodiment, refer to Figures 7 to 9 As shown, the sliding member 160 is provided with an extension edge 163. One end of the extension edge 163 is connected to the side of the sliding member 160 away from the lock beam 170, and the other end of the extension edge 163 abuts against the main lock cylinder 120. When the main lock cylinder 120 rotates, the paddle 123 pushes the extension edge 163, causing the entire frame-shaped sliding member 160 to move axially along the pin 140.

[0091] In some embodiments, the main lock cylinder 120 and the lock beam 170 are located at both ends of the door lock device 100 in the horizontal direction, and the drive member 150 and the bolt 140 are located between the main lock cylinder 120 and the lock beam 170. This helps to form a linear layout of the main lock cylinder 120-intermediate transmission member-lock beam 170, which is beneficial to shortening the transmission path.

[0092] In this embodiment, refer to Figure 10 As shown, the self-locking cylinder 120 points towards the lock beam 170, and the pin 140 includes a connecting block 141 and a stop block 142 arranged opposite to each other. A limiting groove 143 is formed between the connecting block 141 and the stop block 142, and the drive shaft 151 passes through the connecting block 141 and the stop block 142. The first end 161 of the sliding member is connected to the connecting block 141 and drives the pin 140 to move through the connecting block 141.

[0093] The drive shaft 151 passes through the limiting groove 143 of the connecting block 141 and the stop block 142, forming a "shaft-groove" guiding structure to ensure that the pin 140 moves accurately along the horizontal axis. Even if the driving force of the main lock cylinder 120 is eccentric, the limiting groove 143 can constrain the trajectory of the pin 140 through the drive shaft 151 to avoid jamming.

[0094] In this design, the connecting block 141 and the stop block 142 bear the pulling force and the pushing force, respectively. When unlocking, the sliding member 160 pulls the connecting block 141, and the stop block 142 is resisted by the groove of the lock beam 170, forming a "pull force balance". When locking, the sliding member 160 pushes the connecting block 141, and the stop block 142 inserts into the groove of the lock beam 170, forming a "pull force balance". This structure ensures that the pin 140 is subjected to uniform force, reducing the risk of breakage.

[0095] In some embodiments, reference is made to Figure 5 and Figure 7 As shown, it may also include a first elastic element 190, which is sleeved on the drive shaft 151 and located in the limiting groove 143; the drive shaft 151 is provided with a limiting protrusion 152, which is used to limit the movement range of the first elastic element 190.

[0096] For example, the first elastic element 190 can be a torsion spring; for example, the limiting protrusion 152 is an annular boss. One end of the spring abuts against the limiting protrusion 152 on the drive shaft 151, and the other end abuts against the bottom of the limiting groove 143. The limiting protrusion 152 can limit the compression or extension range of the spring and reduce the risk of failure due to excessive deformation of the spring.

[0097] By setting the first elastic element 190, when the emergency lock cylinder drive motor rotates, the spring absorbs the instantaneous driving force of the motor shaft by compression or extension, avoiding a hard collision between the pin 140 and the lock beam 170; at the same time, the spring can buffer the relative movement between the pin 140 and the drive shaft 151, preventing the limit groove 143 and the drive shaft 151 from loosening due to vibration, and improving the vibration resistance level of the lock.

[0098] Furthermore, when the spring is compressed to the limit protrusion 152, it cannot be compressed further, preventing the motor from overloading and burning out. For example, if the locking beam 170 is not fully pressed during emergency locking, the motor will run idle after the spring is compressed to the limit protrusion 152 without damaging the components, providing overload protection.

[0099] In some embodiments, reference is made to Figure 5 As shown, it may also include a circuit board 131, on which a controller is provided. The emergency lock cylinder is electrically connected to the controller and the drive unit 150 respectively. The controller and the drive unit 150 are electrically connected. The emergency lock cylinder is configured to receive a signal of key insertion and control the drive unit 150 to rotate through the controller.

[0100] The circuit board 131 serves as the carrier of the electronic control system, integrating the controller and related circuits to provide power and signal transmission channels for the emergency lock cylinder and the drive unit 150. The emergency lock cylinder is electrically connected to the controller and has a built-in electronic identification module, such as a chip card reader, which can verify the legitimacy of the inserted key. Upon receiving the key insertion signal, it sends a command to the drive unit 150 via the controller. The drive unit 150 is electrically connected to the controller, receives electrical signals, and performs forward and reverse rotation actions, driving the pin 140 to move via springs and other components.

[0101] For example, the controller can connect to the power distribution network master station via a wireless module to upload unlocking records such as time and lock status, and support remote authorized unlocking. For example, the controller can monitor parameters such as motor current and emergency lock cylinder signals in real time, and when an anomaly is detected, it will trigger an alarm via indicator lights or the backend system, facilitating early detection of potential hazards.

[0102] For example, refer to Figure 5 As shown, it may also include a circuit box 132, in which a circuit board 131 is mounted.

[0103] In some embodiments, reference is made to Figure 5 As shown, the main lock cylinder 120 may include a lock cylinder body 121, a lock cylinder shell 122, a lever 123, a lock cylinder fixing shell 124, and a lock cylinder pressure cover 125. The lever 123 is disposed on the lock cylinder body 121, the lock cylinder body 121 is disposed in the lock cylinder shell 122, the lock cylinder shell 122 is disposed in the lock cylinder fixing shell 124, and the lock cylinder pressure cover 125 is connected to the lock cylinder fixing shell 124; the second end 162 of the sliding member abuts against the lever 123.

[0104] In this embodiment, the lock cylinder body 121 is the core rotating component, which can rotate axially after the key is inserted. A paddle 123 is sleeved on the outside, and the two rotate synchronously. The paddle 123 is usually a rigid metal sheet, such as stainless steel, fixed to the outer periphery of the lock cylinder body 121. When the lock cylinder rotates, it pushes the second end 162 of the sliding member, converting the rotational motion into linear motion.

[0105] In this embodiment, the lock cylinder shell 122 is a cylindrical outer shell that encloses the lock cylinder body 121, providing dust and moisture protection. Its outer wall typically has positioning bosses or grooves that mate with the lock cylinder fixing shell 124. The lock cylinder fixing shell 124 is a support structure connected to the main body of the lock shell 110, typically fixed by bolts or clips. It has an internal mounting cavity 111 adapted to the lock cylinder shell 122, restricting radial movement of the lock cylinder shell 122. In this embodiment, the lock cylinder cover 125 is a cover plate covering the top of the lock cylinder fixing shell 124, fastened with screws to prevent axial movement of the lock cylinder body 121, while simultaneously sealing the lock cylinder assembly and improving the protection level.

[0106] In this embodiment, refer to Figure 5As shown, the main lock cylinder 120 may include a lock cylinder clutch 126 and a limit pin 128. The lock cylinder clutch 126 is located between the lock cylinder body 121 and the paddle 123 and is sleeved on the output shaft of the lock cylinder body 121. The limit pin 128 is fixed on the lock cylinder clutch 126.

[0107] Specifically, one end is connected to the output shaft of the lock cylinder body 121 via a key or spline and rotates synchronously with the lock cylinder body 121, while the other end is fixed to the paddle 123 and drives the paddle 123 to rotate, transmitting the rotational motion of the lock cylinder body 121 to the paddle 123, thereby driving the sliding member 160 and the bolt 140 to move.

[0108] In this embodiment, refer to Figure 5 As shown, the main lock cylinder 120 may include a lock cylinder cover 127. The lock cylinder cover 127 is installed at the end of the lock cylinder shell 122 and covers the tail of the lock cylinder body 121, which helps to prevent dust, moisture and other substances from entering the lock cylinder and improves the protection effect.

[0109] In some embodiments, reference is made to Figure 5 , Figures 7 to 9 As shown, a second elastic element 171 may be provided on the locking beam 170, the second elastic element 171 being configured to allow the top of the locking beam 170 to pop out from the lock housing 110 when the pin 140 is disengaged from the locking beam 170.

[0110] For example, the second elastic element 171 can be a tower-shaped spring, which is sleeved on the outer wall of the lock beam 170. When the pin 140 disengages from the insertion slot 172 of the lock beam 170 (e.g., the main lock cylinder 120 or emergency lock cylinder drives the pin 140 to move to the left), the lock beam 170 loses the mechanical constraint of the pin 140, and the second elastic element 171 releases its elastic potential energy, pushing the top of the lock beam 170 out of the opening of the lock housing 110, thus achieving the unlocked state. When locking, the lock beam 170 is manually pressed down, the lock beam 170 compresses the second elastic element 171 and resets, and at the same time, the pin 140 inserts into the slot of the lock beam 170, locking the spring in its compressed state.

[0111] By setting a second elastic element 171, after the pin 140 disengages from the lock beam 170 groove, the second elastic element 171 automatically pops out the lock beam 170, eliminating the need for manual lifting or prying of the lock beam 170. This is especially suitable for operation while wearing gloves or in scenarios where the lock beam 170 is stuck. At the same time, when locking, if the lock beam 170 is manually pressed, the spring absorbs the impact force through compression, preventing deformation or wear caused by hard collision between the lock beam 170 and the lock housing 110, thus extending the service life of the door lock device 100.

[0112] For example, refer to Figure 5 , Figures 7 to 9As shown, the outer wall of the locking beam 170 may also be provided with a retaining spring 173, which is located above the second elastic member 171. The retaining spring 173 may be an annular elastic metal sheet, which is fixed in the annular groove of the locking beam 170 by interference fit or elastic snap.

[0113] By setting the retaining ring 173, when the pin 140 is disengaged from the lock beam 170 groove under the drive of the emergency lock cylinder, the lock beam 170 bounces up under the action of the second elastic element 171. The retaining ring 173 abuts against the top of the lock case 110, limiting the maximum bounce height of the lock beam 170, avoiding excessive bounce of the lock beam 170 and collision with other components, thereby reducing the risk of spring loosening or displacement of the lock beam 170 due to vibration.

[0114] In some embodiments, reference is made to Figure 5 As shown, it may also include a slide plate holder 210 and a slide plate 220. The slide plate 220 has a plate-like structure and is disposed on the slide plate holder 210, horizontally covering the top of the main lock cylinder 120, forming a protective layer for the lock cylinder area together with the lock cylinder housing 122 and the lock cylinder cover 125. The slide plate 220 fixing member has a plate-like structure with two axial through holes for passing through two connecting springs 230 respectively.

[0115] In this embodiment, refer to Figure 2 and Figure 3 As shown, the door lock device 100 may further include a latch 240, which is disposed at the bottom of the lock housing 110 and used to lock the lock beam 170. The latch 240 is generally fixed to the bottom of the lock beam 170, corresponding to the bottom of the lock beam 170. When the lock beam 170 is pressed to lock, the bottom of the lock beam 170 engages with the slot or lock hole of the latch 240, forming a double locking mechanism with the top of the bolt 140, ensuring that the lock beam 170 cannot spring upwards or sway left or right.

[0116] In this embodiment, refer to Figure 10 As shown, the pin 140 has a plug end 144, and the locking beam 170 has a plug groove 172, in which the plug end 144 is plugged into the plug groove 172.

[0117] The plug end 144 is typically cylindrical or frustoconical in shape, matching the shape of the plug groove 172. When the door lock is in the locked state, the bolt 140 moves under the drive of the main lock cylinder 120 or the emergency lock cylinder, and the plug end 144 is fully inserted into the plug groove 172 of the lock beam 170, forming a mechanical lock. When unlocking, the bolt 140 moves in the opposite direction, and the plug end 144 disengages from the plug groove 172, releasing the lock. This structure utilizes a plug-in mechanical engagement to achieve the switching of the door lock state.

[0118] This embodiment provides a door lock device that includes a main lock cylinder and an emergency lock cylinder. The two lock cylinders do not interfere with each other and can be operated independently to open and close the lock. When the main lock cylinder malfunctions and cannot be opened, the lock can be opened through the emergency lock cylinder, reducing the risk of lock failure and improving work efficiency.

[0119] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0120] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
