[0042] The present utility model provides a lock 100 with a padlock 3, as Figures 1 to 7 shown, including: a lock body structure 1, a handle mechanism 2, and a padlock 3. The lock body structure 1 includes a support frame 10 and a base body 11. The base body 11 is installed on the support frame 10, and the base body 11 is provided with a hanging hole 111; the handle mechanism 2 includes a gripping member 21, a latch assembly 22, and a locking assembly 23. The latch assembly 22 is movably arranged in the support frame 10. In a first direction 5, the latch assembly 22 is rotatably engaged with the support frame 10; a first end of the gripping member 21 is movably installed on the latch assembly 22. In a second direction 6, the gripping member 21 is rotatably engaged with the latch assembly 22; the locking assembly 23 is installed at a second end of the gripping member 21. The support frame 10 has a locking groove 14 that cooperates with the locking assembly 23; the gripping member 21 has a through hole 211 for the base body 11 to pass through. The padlock 3 is cooperated with the base body 11 through the hanging hole 111, and the padlock 3 is used to abut against the gripping member 21. Specifically, this lock 100 is used to be installed on a power distribution cabinet. After the locking assembly 23 is engaged with the locking groove 14, the latch assembly 22 is locked with the cabinet door or the door frame, restricting the opening of the cabinet door of the power distribution cabinet and realizing the locking function. When the locking assembly 23 is damaged, the gripping member 21 and the support frame 10 can also be locked through the padlock 3. After the base body 11 passes through the through hole 211, the padlock 3 is hung on the hanging hole 111 of the base body 11. The padlock 3 is used to abut against the gripping member 21, restricting the gripping member 21 from being opened from the support frame 10, thereby realizing the locking of the lock 100. This lock 100 is provided with a padlock 3 on the hanging hole 111 to avoid the inability to realize the locking function due to the damage of the locking assembly 23; such a lock 100 has sufficient time to repair or replace the locking assembly 23, avoiding the abnormal use of the power distribution cabinet due to the failure of the locking assembly 23, and at the same time avoiding the phenomenon of operation errors caused by the inability to lock the power distribution cabinet.

[0043] In some embodiments, as Figure 5 and Figure 6 shown, in the application of management authority of this lock 100, this lock 100 has a dual-locking function. Therefore, this lock 100 is equipped with two keys. One key is used to control the locking of the locking assembly 23 and the locking groove 14, and the other key is used to control the locking of the padlock 3 and the base body 11. Any one of the above locking assembly 23 and padlock 3 can realize the locking of this lock 100. This lock 100 has a dual-locking function, and two keys are required to open this lock 100. Therefore, two keys of the lock 100 can be set as two-level unlocking authorities. When an operator needs to operate the power distribution cabinet, the operator needs to apply to two different authority administrators. After the consent of the two-level authority administrators, the operator can obtain two keys, so that the operator has the qualification to operate the power distribution cabinet. It can be seen that when this lock 100 is applied to a relatively important power distribution cabinet, by setting two levels of authorities, the practical significance of this lock 100 in this embodiment can be reflected.

[0044] In some embodiments, as Figures 1 to 3 , Figure 7 shown, the support frame 10 has a slot 12, and the slot 12 penetrates from the inner side to the outer side of the support frame 10; a through groove 112 is formed by the upward depression of the bottom of the seat body 11, and the through groove 112 communicates with the slot 12; the holding member 21 has a first limiting block 212, and the lock 100 further has a display board 4, and a limiting groove is formed on the display board 4. The slot 12 is used for the display board 4 to pass through so that the first limiting block 212 cooperates with the limiting groove. Specifically, by providing the slot 12 in the support frame 10 and allowing the display board 4 to pass through the slot 12, when the holding member 21 is locked with the support frame 10, the first limiting block 212 of the holding member 21 is clamped with the limiting groove of the display board 4, thereby restricting the movement of the display board 4 in the slot 12 and preventing the display board 4 from disengaging from the slot 12 after the holding member 21 is locked with the support frame 10, improving the stability of the display board 4 on the lock 100. This display board 4 is used to display the specific state of the power distribution cabinet. The display board 4 can be used to display different states such as the power distribution cabinet is in operation, under maintenance, etc. The display board 4 presents the operating state of the power distribution cabinet more directly, facilitating the operator to directly understand the state information of the power distribution cabinet.

[0045] Preferably, as Figure 2 and Figure 3 shown, the support frame 10 has a clamping groove 13, the locking groove 14 communicates with the clamping groove 13, and at least a part of the holding member 21 is used to be clamped with the clamping groove 13, and the seat body 11 is arranged in the clamping groove 13. Specifically, when the locking assembly 23 is separated from the locking groove 14, the lock 100 is in the unlocked state; in the second direction 6, the holding member 21 and the bolt assembly 22 are rotated. After the holding member 21 rotates a certain arc, the holding member 21 is separated from the clamping groove 13 of the support frame 10. At this time, the holding member 21 can drive the bolt assembly 22 to rotate in the first direction 5, and the bolt assembly 22 rotates to a preset position in the first direction 5 to open the cabinet door. When the locking assembly 23 cooperates with the locking groove 14, the holding member 21 is clamped with the clamping groove 13, and the support frame 10 restricts the movement of the holding member 21 in the second direction 6, realizing the locking function of the lock 100. This lock 100 is a floating lock, and this lock 100 is generally installed on the cabinet door of the power distribution cabinet. The bolt assembly 22 of the lock 100 is used to abut against the door frame to realize the locking function.

[0046] Preferably, as Figure 3As shown, the seat body 11 is a conical structure, the hanging hole 111 is arranged at the smallest end of the seat body 11, and the largest end of the seat body 11 is installed on the support frame 10. Specifically, when the holding member 21 moves in the second direction 6, the movement track of the holding member 21 is arc-shaped. If the seat body 11 is square, the through hole 211 of the holding member 21 needs to be set larger to prevent the seat body 11 from interfering with the movement of the holding member 21. After the holding member 21 is clamped with the support frame 10, in order to improve the compactness between the seat body 11 and the holding member 21, the through hole 211 needs to be set just large enough for the seat body 11 to pass through. Therefore, setting the seat body 11 as a conical structure can prevent the seat body 11 from interfering with the movement of the holding member 21.

[0047] In some embodiments, as Figure 2 and Figure 3 shown, the bolt assembly 22 includes a rotating seat 224, a steel bolt 221, a first pin shaft 226, and a torsion spring 227. The rotating seat 224 is rotatably installed in the support frame 10. The first pin shaft 226 is installed at the first end of the rotating seat 224, and the steel bolt 221 is installed at the second end of the rotating seat 224; the torsion spring 227 is sleeved on the first end of the first pin shaft 226, and the end of the holding member 21 is sleeved on the second end of the first pin shaft 226. In the second direction 6, the holding member 21 is rotatably connected to the rotating seat 224 through the first pin shaft 226; both ends of the torsion spring 227 abut against the holding member 21 and the rotating seat 224 respectively. Specifically, when the locking assembly 23 cooperates with the locking groove 14, the holding member 21 is clamped with the clamping groove 13 of the support frame 10, and the holding member 21 presses the torsion spring 227 to make the torsion spring 227 have a reverse acting force. After the locking assembly 23 is separated from the locking groove 14, the reverse acting force generated by the torsion spring 227 drives the holding member 21 to move in the second direction 6, so that the holding member 21 pops open on the support frame 10, and the holding member 21 moves out of the clamping groove 13; when the holding member 21 is held by hand and moved in the first direction 5, the holding member 21 drives the rotating seat 224 to move in the first direction 5, the rotating seat 224 drives the steel bolt 221 to rotate, and the steel bolt 221 is separated from the door frame, realizing the opening operation of the electric cabinet door.

[0048] Preferably, as Figure 2 and Figure 3As shown, the bolt assembly 22 further includes a housing 222, a first fastener 223, and a second fastener 225. The housing 222 is mounted on the support frame 10 through the first fastener 223. The housing 222 is sleeved outside the rotating seat 224, and the rotating seat 224 is rotatably connected to the housing 222. The steel bolt 221 has a mounting hole for the second fastener 225 to pass through, and the steel bolt 221 is fixedly connected to the rotating seat 224 through the second fastener 225. Specifically, the housing 222 is arranged on the inner side of the cabinet door, and the support frame 10 is arranged on the outer side of the cabinet door. The housing 222 is fixed to the support frame 10 through the first fastener 223, so as to realize the fixed installation of the lock 100 on the cabinet door. Since the steel bolt 221 is fixed to the rotating seat 224 through the second fastener 225, by operating the holding member 21 on the outer side of the cabinet door, the holding member 21 is driven to drive the rotating seat 224 to rotate, so as to realize the rotating seat 224 driving the steel bolt 221 to rotate, and further realize the opening operation of the electric cabinet door.

[0049] In some embodiments, as Figure 3 shown, the locking assembly 23 includes a lock core 231, a toggle shaft 232, and a lock tongue plate 233. The lock core 231 is installed in the holding member 21. The lock core 231 has a lock hole, and the lock hole is exposed relative to the holding member 21. The toggle shaft 232 is installed on the circumference of the lock core 231. The lock tongue plate 233 is movably arranged on the bottom wall of the support frame 10. At least part of the toggle shaft 232 is used to abut against the lock tongue plate 233, so that the lock tongue plate 233 is clamped with the lock groove 14. Specifically, a dust cover 24 is arranged on the holding member 21. The dust cover 24 is used to seal the lock hole. After the dust cover 24 is opened, the key is inserted into the lock hole and paired with the code chip of the lock core 231. When the code chip correctly identifies the identity of the key, the key can be further inserted into the lock core 231 and drive the toggle shaft 232 to rotate on the circumference of the lock core 231. When the toggle shaft 232 moves, it pushes the lock tongue plate 233 to move, so as to drive the lock tongue plate 233 to separate from the lock groove 14, and realize the unlocking of the locking assembly 23 and the lock groove 14. The specific structure of the lock tongue plate 233 can refer to the prior art. For example, Chinese Patent No. CN202323201431.8 discloses a cabinet lock, and the lock tongue structure of this cabinet lock can be applied to this application.

[0050] In some embodiments, as Figure 3 and Figure 4As shown, the lock 100 further has a protection device 15. The protection device 15 includes a pressing block 151, a reset member 154, and a second limiting block 153. The second limiting block 153 is installed on the side wall of the holding member 21, and the pressing block 151 has a hook groove 152 that cooperates with the second limiting block 153; the first end of the reset member 154 is installed on the pressing block 151, and the second end of the reset member 154 is installed on the support frame 10. Specifically, after the locking assembly 23 is separated from the locking groove 14, the holding member 21 still cannot be removed from the card slot 13. An external force needs to be applied to the pressing block 151 to separate the hook groove 152 of the pressing block 151 from the second limiting block 153 on the holding member 21 to realize the unlocking operation of the electrical cabinet door. The significance of setting the protection device 15 is that even if the lock 100 is manually operated to be opened, the holding member 21 will still be restricted in the card slot 13 by the protection device 15. It is necessary to operate the protection device 15 to separate the second limiting block 153 from the hook groove 152, so that the holding member 21 is ejected out of the support frame 10 by the torsion spring 227, avoiding the occurrence of misoperation and realizing the function of secondary protection.

[0051] Preferably, as Figure 4 shown, the protection device 15 further has a second pin shaft 155. The first end of the second pin shaft 155 is installed on the support frame 10, and the pressing block 151 is installed on the second end of the second pin shaft 155 and is rotationally matched with the second pin shaft 155; the pressing block 151 has a first limiting post, and the support frame 10 has a second limiting post corresponding to the first limiting post. The two ends of the reset member 154 are respectively sleeved outside the first limiting post and the second limiting post, and the two ends of the reset member 154 are respectively abutted against the pressing block 151 and the support frame 10. Specifically, the reset member 154 is a spring. By respectively arranging the first limiting post and the second limiting post on the pressing block 151 and the support frame 10, the two ends of the spring are respectively sleeved on the first limiting post and the second limiting post to limit the telescopic movement of the spring and improve the stability of the spring during telescopic movement. Moreover, the pressing block 151 is rotationally matched with the support frame 10 through the second pin shaft 155. The second pin shaft 155 limits the movement path of the pressing block 151. After the pressing block 151 moves, it is reset by the reset member 154, so that the pressing block 151 can be used repeatedly, improving the practicability of the protection device 15.

[0052] In some embodiments, as Figure 3As shown, the support frame 10 has ten assembly holes 16 which are arranged along the length direction of the support frame 10; any one of the assembly holes 16 is for the first fastener 223 to pass through, so that the first fastener 223 mounts the support frame 10 on the door frame or the cabinet door. Specifically, when the lock 100 is installed, the installation environment of the lock 100 may be relatively narrow; since there are ten assembly holes 16 on the support frame 10, any two assembly holes 16 are respectively for two first fasteners 223 to pass through, thus realizing the two-point fixation of the support frame 10 and the cabinet door. In this way, the installation position of the support frame 10 is relatively flexible, facilitating the lock 100 to adapt to a relatively narrow installation environment and improving the installation efficiency of the lock 100.

[0053] It should be noted that the lock 100 has a dual locking function. The locking assembly 23 and the locking groove 14 achieve locking, and the padlock 3 and the seat body 11 cooperate to achieve locking. In terms of the locking of the lock 100, any one of the locking methods can be realized. In terms of unlocking, two locking modes need to be opened simultaneously. In other locks 100, the function of realizing dual locking by using the padlock 3 and the locking assembly 23 is within the protection scope of this application.

[0054] When referring to the drawings for explanation, new features that appear are described; in order to avoid repeated reference to the drawings resulting in a less concise description, features that have been described clearly are not cited in the drawings one by one.

[0055] The purpose of the above embodiments is to exemplarily reproduce and deduce the technical solutions of the present utility model, and to completely describe the technical solutions, purposes and effects of the present utility model. The purpose is to enable the public to understand the disclosed content of the present utility model more thoroughly and comprehensively, and it does not limit the protection scope of the present utility model.

[0056] The above embodiments are not an exhaustive list of the present utility model. In addition, there may be multiple other implementation manners not listed here. Any replacement and improvement made on the basis of not violating the concept of the present utility model fall within the protection scope of the present utility model.
