Description

Technical Field

[0001] The present application relates to the technical field of lock devices, and in particular to a trolley hole lock and a lock. Background Art

[0002] An operating hole is generally provided on the door of the switch cabinet, which is used to swing the circuit breaker or functional trolley from the test position to the working position. However, the operating hole is generally exposed outside the door of the switch cabinet, and other personnel can also operate it without authorization, which has very low safety.

[0003] In order to improve the safety of the switch cabinet, a trolley hole lock is usually installed on the operating hole. When the switch cabinet does not need to be operated, the operating hole can be blocked by the locking plate of the trolley hole lock to prevent other personnel from operating without authorization. When the switch cabinet needs to be operated, the trolley hole lock can be unlocked to allow the locking plate to avoid the operating hole for the operator to operate.

[0004] In the prior art, the locking plate is usually arranged parallel to the cabinet door surface where the operating hole is located, and the lock core assembly that locks the locking plate is usually arranged perpendicular to the cabinet door surface where the operating hole is located, that is, the length direction of the lock core assembly is perpendicular to the locking plate, so that the keyhole can extend in the vertical direction of the cabinet door surface to facilitate the operator to operate the handcart hole lock. In this way, the length of the lock core assembly in the length direction will seriously affect the overall thickness of the handcart hole lock, so that the handcart hole lock needs to occupy more space in the direction perpendicular to the cabinet door surface. Utility Model Content

[0005] The main purpose of the present application is to provide a trolley hole lock, which is designed to allow the lock core assembly to be flipped out or back relative to the mounting base. When the trolley hole lock is not operated, the lock core assembly can be flipped back so that the length direction of the lock core is parallel to the surface of the cabinet door, thereby shortening the overall thickness of the trolley hole lock.

[0013] In some embodiments of the present application, the locking plate rotates relative to the mounting base and has a blocking position for blocking the operating hole and a avoiding position for avoiding the operating hole. The trolley hole lock also includes a first elastic member, which is installed between the mounting base and the locking plate. The first elastic member provides elastic force to drive the locking plate so that the locking plate has a tendency to move from the blocking position toward the avoiding position.

[0015] In some embodiments of the present application, a locking block is provided at one end of the locking structure facing the locking plate, and at least two adjacent abutment surfaces are provided on the peripheral side of the locking block. When the locking block cooperates with the locking groove, the groove wall of the locking groove abuts against the corresponding abutment surface, and the locking structure can rotate relative to the locking groove to switch different abutment surfaces to abut against the groove wall of the locking groove.

[0016] In some embodiments of the present application, the lock core assembly also includes a lock core shell, the lock core shell is provided with a lock core cavity, wherein the rotating portion is formed on the outer wall of the lock core shell, the mounting hole is also connected to the lock core cavity, and the peripheral side of the mounting hole is provided with a rotating portion exposed on the outer wall of the lock core shell, and the rotating portion is rotatably installed on the mounting seat.

[0017] In some embodiments of the present application, the locking structure includes a locking rod and a second elastic member, the locking rod is slidably mounted in the lock core cavity, the second elastic member elastically abuts against an end of the locking rod away from the locking plate, and the second elastic member provides an elastic force to drive the locking rod, so that the locking rod has a tendency to move toward the locking plate;

[0018] The lock core assembly also includes a lock core, which is installed in the lock core cavity and is transmission-connected to the locking rod. The lock core is used to drive the locking rod to slide in a direction away from the locking plate and to disengage the locking rod from the locking groove to unlock the locking plate and the mounting seat.

During the rotation process, the lock core assembly can keep the locking plate and the mounting seat in a locked state or an unlocked state through the locking rod, and the rotation setting of the lock core assembly can make the lock core assembly flip out or flip back relative to the mounting seat. At the same time, since the locking plate is usually arranged parallel to the cabinet door surface where the operating hole is located, the rotation axis of the lock core assembly is arranged perpendicular to the rotation axis of the locking plate, so that the rotation axis of the lock core assembly is parallel to the surface of the cabinet door. That is, one end of the lock core assembly in the length direction can be rotatably connected to the mounting seat. When the hand-cart hole lock is not operated, the lock core assembly can be flipped back so that the length direction of the lock core assembly can be parallel to the surface of the cabinet door, shortening the overall thickness of the hand-cart hole lock to reduce the space occupied by the hand-cart hole lock in the direction perpendicular to the cabinet door surface. When the hand-cart hole lock needs to be operated, the lock core assembly can be flipped out for easy operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The utility model proposes a handcart hole lock 100, which is used to be installed on the cabinet door of the switch cabinet. Figures 1 to 6 In the embodiment of the utility model, the trolley hole lock 100 includes a mounting seat 10, a locking plate 20, and a lock core assembly 30.

[0037] The mounting base 10 can be directly mounted and fixed on the cabinet door of the switch cabinet to fix the trolley hole lock 100 on the cabinet door, and the mounting base 10 can be fixed on the cabinet door by a fixed connection method such as bonding, welding, and threaded connection. In some embodiments, the mounting base 10 may include a mounting plate 111 and a bottom shell 112, and the mounting plate 111 and the bottom shell 112 are respectively arranged on the inner side and the outer side of the cabinet door, and then the mounting plate 111 and the bottom shell 112 are fixedly mounted on the cabinet door by a screw structure.

[0038] The locking plate 20 is rotatably mounted on the mounting seat 10, so that the locking plate 20 can block or avoid the operating hole of the cabinet door when it rotates relative to the mounting seat 10. The locking plate 20 is in the shape of a flat plate, and the locking plate 20 rotates relative to the mounting seat 10, and moves in the direction close to the operating hole, so that part of the locking plate 20 can cover the operating hole to achieve the purpose of blocking the operating hole, and moves in the direction away from the operating hole, so that the locking plate 20 can avoid the operating hole, wherein the rotation angle of the locking plate 20 relative to the mounting seat 10 can be 80 degrees, 90 degrees, 100 degrees, etc., and the power for the locking plate 20 to rotate relative to the mounting seat 10 can come from manual operation, and an elastic member can also be provided for elastic reset.

[0039] It can be understood that the surface of the cabinet door is defined as the installation surface 111a, or the side of the mounting plate 111 that abuts the cabinet door is defined as the installation surface 111a, or the side of the bottom shell 112 that abuts the cabinet door is defined as the installation surface 111a, and the locking plate 20 is rotatably installed on the mounting seat 10, and will be spaced apart from the installation surface 111a, or closely attached to the installation surface 111a, and the axis of rotation of the locking plate 20 is perpendicular to the installation surface 111a, and the locking plate 20 can rotate clockwise or counterclockwise and move toward the direction close to the operating hole to cover the operating hole.

[0040] The lock core assembly 30 is rotatably mounted on the mounting base 10, so that the lock core assembly 30 can rotate relative to the mounting base 10, and the axis of rotation of the lock core assembly 30 is perpendicular to the axis of rotation of the locking plate 20. Similarly, the rotation angle of the lock core assembly 30 relative to the mounting base 10 can be 80 degrees, 90 degrees, 100 degrees, etc.

[0041] The rotation axis of the lock core assembly 30 is arranged perpendicular to the rotation axis of the locking plate 20. The lock core assembly 30 and the mounting base 10 rotate relative to each other, and the lock core assembly 30 can be flipped out or flipped back relative to the mounting base 10, that is, the lock core assembly 30 can be switched between a state in which the length direction is parallel to the mounting surface 111a and a state in which the length direction is perpendicular to the mounting surface 111a.

[0042] The lock core assembly 30 is provided with a mounting hole 324 connected to the mounting seat 10 . The lock core assembly 30 includes a movable locking structure 31 . The locking structure 31 cooperates with the locking plate 20 through the mounting hole 324 to lock or unlock the locking plate 20 and the mounting seat 10 .

[0043] The locking structure 31 cooperates with the locking plate 20 through the mounting hole 324, so that when the lock core assembly 30 rotates relative to the mounting seat 10, it will not affect the cooperation between the locking structure 31 and the locking plate 20. During the rotation of the lock core assembly 30, the locking structure 31 can keep the locking plate 20 and the mounting seat 10 in a locked state or an unlocked state.

[0044] The utility model adopts the above technical scheme to respectively rotate and install the mounting parts of the locking plate 20 and the rotating part 323 of the lock core assembly 30 on the mounting seat 10, and the rotation axis of the lock core assembly 30 is arranged perpendicularly to the rotation axis of the locking plate 20, and the locking structure 31 cooperates with the locking plate 20 through the mounting hole 324 on the rotating part 323 to lock or unlock the locking plate 20 and the mounting seat 10. With such arrangement, when the lock core assembly 30 rotates relative to the mounting seat 10, it will not affect the cooperation between the locking structure 31 and the locking plate 20. During the rotation process, the lock core assembly 30 can keep the locking plate 20 and the mounting seat 10 in a locked state or an unlocked state through the locking structure 31, and the rotation setting of the lock core assembly 30 can make the lock core assembly 30 flip out or flip back relative to the mounting seat 10. At the same time, since the locking plate 20 is usually arranged parallel to the cabinet door surface where the operating hole is located, the rotation axis of the lock core assembly 30 is perpendicular to the rotation axis of the locking plate 20. The lock core assembly 30 is vertically arranged so that the axis of rotation of the lock core assembly 30 is parallel to the surface of the cabinet door, that is, one end of the lock core assembly 30 in the length direction can be rotatably connected to the mounting base 10, and when the handcart hole lock 100 is not operated, the lock core assembly 30 can be flipped back so that the length direction of the lock core assembly 30 can be parallel to the surface of the cabinet door, shortening the overall thickness of the handcart hole lock 100 to reduce the space occupied by the handcart hole lock 100 in the direction perpendicular to the surface of the cabinet door, and when the handcart hole lock 100 needs to be operated, the lock core assembly 30 can be flipped out for easy operation.

[0045] In some examples, such as Figure 1 and Figure 6 As shown, the mounting seat 10 is provided with a receiving groove 12 , and the lock core assembly 30 can be rotated relative to the mounting seat 10 and extend from the notch of the receiving groove 12 or be received in the receiving groove 12 .

[0046] The receiving groove 12 is mainly used to receive and protect the lock core assembly 30, so the shape of the receiving groove 12 should be adapted to the outer contour of the lock core assembly 30. Figure 6 In the present embodiment, the receiving groove 12 is provided with openings on three sides, one end of the lock core assembly 30 in the length direction is rotatably installed in the receiving groove 12 and covers one side opening of the receiving groove 12, and the lock core assembly 30 can be extended out or accommodated in the receiving groove 12 by rotating relative to the mounting seat 10.

[0047] With such arrangement, when the lock core assembly 30 does not need to be operated, the lock core assembly 30 can be accommodated in the accommodating groove 12 to play a protective role.

[0048] In some examples, such as Figure 6As shown, the groove wall of the receiving groove 12 is convexly provided with a positioning portion 121, and the outer surface of the lock core assembly 30 is concavely provided with a matching portion 321 that matches the positioning portion 121. The shapes of the positioning portion 121 and the matching portion 321 can be various. In this embodiment, the positioning portion 121 is a "U"-shaped protrusion convexly provided on the receiving groove 12, and the matching portion 321 is a "U"-shaped concave portion concavely provided on the outer surface of the lock core assembly 30, and the positioning portion 121 and the matching portion 321 are adapted to each other.

[0049] With such arrangement, when the lock core assembly 30 is accommodated in the accommodating groove 12 , the lock core assembly 30 can be positioned and fixed by the interaction between the positioning portion 121 and the matching portion 321 , so that the lock core assembly 30 maintains a relatively fixed position.

[0050] In some examples, such as Figures 2 to 7 As shown, the locking plate 20 is provided with a locking groove 23, and the locking structure 31 can slide through the mounting hole 324 in a direction close to the locking plate 20 and cooperate with the locking groove 23 to lock the locking plate 20 and the mounting seat 10. The locking structure 31 can slide through the mounting hole 324 in a direction away from the locking plate 20 and disengage from the locking groove 23 to unlock the locking plate 20 and the mounting seat 10.

[0051] In some embodiments, one end of the locking rod 311 of the locking structure 31 cooperates with the locking groove 23 .

[0052] In this way, when the locking plate 20 blocks the operating hole, the locking structure 31 can slide toward the locking plate 20 and be inserted into the locking groove 23, thereby limiting the rotation of the locking plate 20 and locking the locking plate 20 with the mounting seat 10. The locking structure 31 and the locking groove 23 are plug-fitted, and even if the lock core assembly 30 rotates, it will not affect the locking structure 31 to limit the rotation of the locking plate 20.

[0053] In some examples, such as Figure 2 and Figure 7 As shown, the locking plate 20 rotates relative to the mounting base 10, and has a blocking position for blocking the operating hole and a avoiding position for avoiding the operating hole. The trolley hole lock 100 also includes a first elastic member 40, which is installed between the mounting base 10 and the locking plate 20. The first elastic member 40 provides elastic force to drive the locking plate 20, so that the locking plate 20 has a tendency to move from the blocking position toward the avoiding position.

[0054] In this way, when the locking structure 31 slides in the direction away from the locking plate 20 and disengages from the locking groove 23 to unlock the locking plate 20 and the mounting seat 10, the locking plate 20 can be driven by the elastic force of the first elastic member 40 to move from the blocking position toward the avoidance position, thereby improving the efficiency of unlocking the avoidance hole.

[0055] In some examples, such as Figures 2 to 7 As shown, the first elastic member 40 is a torsion spring, the mounting seat 10 includes a shell 11, the shell 11 is provided with a mounting cavity 114 and an avoidance opening 116 connected to the mounting cavity 114, a mounting boss 115 is convexly provided in the mounting cavity 114, the locking plate 20 includes a connecting portion 21 and a shielding portion 22, the connecting portion 21 is rotatably mounted on the mounting boss 115, and a torsion spring is also installed between the connecting portion 21 and the mounting boss 115, and the shielding portion 22 extends out of the mounting cavity 114 through the avoidance opening 116.

[0056] In some embodiments, the housing 11 includes a bottom shell 112 and an upper cover 113 . The upper cover 113 covers the bottom shell 112 to form a mounting cavity 114 . The escape opening 116 is formed in a gap between the bottom shell 112 and the upper cover 113 .

[0057] With such arrangement, the elastic reset structure of the locking plate 20 is simple and reliable, which can improve the assembly efficiency of the trolley hole lock 100 , and can protect the internal structure of the installation cavity 114 through the shell 11 , thereby improving the durability of the trolley hole lock 100 .

[0058] In some examples, such as Figure 2 , Figure 3 and Figure 6 As shown, a locking block 313 is provided at one end of the locking structure 31 facing the locking plate 20, and at least two adjacent abutment surfaces 314 are provided on the peripheral side of the locking block 313. When the locking block 313 cooperates with the locking groove 23, the groove wall of the locking groove 23 abuts against the corresponding abutment surface 314, and the locking structure 31 can rotate relative to the locking groove 23 to switch different abutment surfaces 314 to abut against the groove wall of the locking groove 23.

[0059] Among them, different angles such as 80 degrees, 90 degrees, and 100 degrees can be formed between two adjacent abutting surfaces 314 . Preferably, the locking block 313 is in a cube shape, and an angle of 90 degrees is formed between two adjacent abutting surfaces 314 .

[0060] In this way, when the lock core assembly 30 rotates relative to the mounting base 10, the lock core assembly 30 can be kept in a certain position due to the cooperation between the abutment surface 314 and the locking groove 23. When the locking structure 31 moves in a direction away from the locking plate 20 and causes the locking block 313 to disengage from the locking groove 23, the lock core assembly 30 loses its force and can fall back naturally.

[0061] In some examples, such as Figures 2 to 7 As shown, the lock core assembly 30 also includes a lock core shell 32, which is provided with a lock core cavity 322, wherein the mounting hole 324 is also connected to the lock core cavity 322, and the surrounding side of the mounting hole 324 is provided with a rotating part 323 exposed on the outer wall of the lock core shell 32, and the rotating part 323 is rotatably installed on the mounting seat 10.

[0062] In this arrangement, the lock core assembly 30 is rotatably connected to the mounting seat 10 via the rotating portion 323 arranged on the periphery of the mounting hole 324. The rotation of the lock core assembly 30 relative to the mounting seat 10 will not affect the locking of the locking structure 31 on the locking plate 20. The structure is simple, which facilitates the assembly of the trolley hole lock 100.

[0063] In some examples, such as Figures 2 to 7 As shown, the locking structure 31 includes a locking rod 311 and a second elastic member 312. The locking rod 311 is slidably installed in the lock core cavity 322. The second elastic member 312 is elastically abutted against one end of the locking rod 311 away from the locking plate 20. The second elastic member 312 provides elastic force to drive the locking rod 311, so that the locking rod 311 has a tendency to move toward the locking plate 20. The lock core assembly 30 also includes a lock core 34. The lock core 34 is installed in the lock core cavity 322 and is transmission-connected to the locking rod 311. The lock core 34 is used to drive the locking rod 311 to slide in a direction away from the locking plate 20 and to disengage the locking rod 311 from the locking groove 23 to unlock the locking plate 20 and the mounting base 10.

[0064] With such a configuration, when the locking plate 20 needs to be rotated to a position that avoids the operation hole, the locking rod 311 can be driven to slide in a direction away from the locking plate 20 by operating the lock core 34, so as to unlock the locking plate 20 and the mounting seat 10, and then the locking plate 20 can be rotated to achieve the purpose of avoiding the operation hole. When the locking plate 20 needs to be locked in a position that blocks the operation hole, the locking plate 20 is first rotated to a position that blocks the operation hole, and then the second elastic member 312 provides an elastic force to drive the locking rod 311 to move toward the locking plate 20, so that the locking rod 311 cooperates with the locking groove 23 to lock the locking plate 20 and the mounting seat 10, so as to achieve the locking of the locking plate 20 in a position that blocks the operation hole.

[0065] In some examples, such as Figures 2 to 7 As shown, the locking rod 311 is axially provided with an unlocking groove 315, the lock core 34 is rotatably installed in the lock core cavity 322, and the lock core 34 is provided with an unlocking portion 341. When the lock core 34 rotates, the unlocking portion 341 can be abutted against the side wall of the unlocking groove 315 away from the locking plate 20 to drive the locking rod 311 to move in a direction away from the locking plate 20.

[0066] The unlocking portion 341 may be a cam or a protrusion with a semicircular cross section, and the unlocking portion 341 may be fixedly connected to the main body of the lock core 34 by screws.

[0067] In this way, the unlocking portion 341 abuts against the side wall of the unlocking groove 315 away from the locking plate 20, driving the locking rod 311 to move in a direction away from the locking plate 20, so that the locking rod 311 disengages from the locking groove 23 toward one end of the locking plate 20, thereby unlocking the locking plate 20.

[0068] The present application also proposes a lock, which includes a computer key and a handcart hole lock 100. The specific structure of the handcart hole lock 100 refers to the above embodiment. Since the present lock adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the computer key is compatible with the handcart hole lock 100, and the lock core assembly 30 also includes a wireless code chip 50, which is used to send a signal to the computer key. In some embodiments, the wireless code chip 50 is set on the keyhole side of the lock core 34.

[0069] With this arrangement, the wireless code chip 50 provides a unique ID code for the lock. When the computer key is inserted into the lock core 34, the wireless code chip 50 is identified and the lock ID code is identified. If the lock ID code is consistent with the lock ID code authorized by the computer key operation ticket, the lock operation authority is obtained.
