Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a five-protection smart lock for outdoor equipment in a power distribution network. Background Art

[0002] The intelligent online five-protection system primarily consists of an intelligent anti-error backend, computer keys, a wireless communication network, and smart locks. Currently, the anti-error host typically transmits the correct operating steps after a simulated rehearsal to the computer key, which then unlocks the locked lock. Lock status information is still collected by the computer key, which has poor reliability and complex operation. Therefore, most of the time, operators still perform direct unlocking on-site. Existing distribution network equipment has a large number of connecting wires installed inside. Currently, power transmission is not adapted, and copper wires are mostly used for power supply processing to reduce resistance and improve transmission efficiency. The high value of copper wires does not effectively prevent criminals and idle personnel from accessing distribution network equipment, causing damage to facilities and personnel. Dedicated protective locks are used for locking.

[0003] Most existing locks use intelligent unlocking methods to achieve anti-theft measures. Their structures are mostly J-shaped lock buckles and lock body components. The intelligent locking function is formed by setting intelligent five-protection configurations inside the lock body. However, although such locks have technical anti-theft functions, their protection against violent breaking methods is basically the same as that of conventional locks, and they cannot provide good anti-violent breaking effects. Therefore, how to propose a five-protection smart lock for distribution network outdoor equipment with anti-violent breaking function is particularly important. In view of this, we propose a five-protection smart lock for distribution network outdoor equipment. Summary of the Invention

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] Example 1: A five-protection smart lock for outdoor equipment in a distribution network, see Figures 1 to 5, including a lock body 1, a five-protection smart lock core module 2, a lock buckle 3, a protective block 4 and a driving gear 5; the lock body 1 is sequentially provided with an auxiliary cavity and a combination cavity; the five-protection smart lock core module 2 is arranged in the combination cavity and extends into the auxiliary cavity; the lock buckle 3 is arranged on the five-protection smart lock core module 2; wherein, the gap between the lock buckle 3 and the lock body 1 constitutes a protective cavity; wherein, the lock buckle 3 is J-shaped; the protective block 4 is arranged in the auxiliary cavity and connects the protective cavity; the driving gear 5 movably connects one side of the auxiliary cavity to connect the lock buckle 3 and the protective block 4; wherein, the protective block 4 constitutes an anti-violent demolition structure when the lock buckle 3 and the lock body 1 are locked. The present invention sets a protective block 4, so that the five-protection smart lock of the distribution network outdoor equipment fully fills the protective cavity formed by the lock buckle 3 and the lock body 1 in the locked state, so that the lock buckle 3 cannot be violently dismantled by using a crowbar to insert the force to borrow the lock buckle 3, effectively improving the anti-violent dismantling effect of the five-protection smart lock, improving the anti-theft performance of the distribution network outdoor equipment, and effectively preventing various situations such as damage to social property and personal accidents caused by contact with idle people.

[0029] Specifically, the lock body 1 is provided with a limit slot 101, an operating slot 102, and a central axis slot 103 in sequence relative to the auxiliary cavity; wherein, a dislocation slot 1011 is provided on either side of the limit slot 101 relative to the same center of rotation of the lock catch 3; wherein, auxiliary guide slots 1021 are provided on both sides of the middle end of the operating slot 102. The dislocation slot 1011 of the present invention is provided to adapt to the lock catch 3 in a relatively short vertical movable stroke, achieving the rotational dislocation required for the normal operation of the lock catch 3 within a relatively fixed volume, and realizing the basic functions of basic installation or removal of the five-protection smart lock; at the same time, the provision of the auxiliary guide slot 1021 is used to perform basic positioning and guiding work for the upward and downward movement of the protective block 4, while preventing the protective block 4 from falling off when unlocked.

[0030] Furthermore, the lock buckle 3 is composed of a rotating shaft 301, an arc block 302, a limit block 303 and an engaging protrusion block 304; the rotating shaft 301 is movably arranged on the locking end of the five-defense intelligent lock core module 2; wherein, a locking through groove 3011 is provided on the surface of the rotating shaft 301; the arc block 302 is fixedly arranged on the high end of the rotating shaft 301; the limit block 303 is fixedly arranged at the end of the arc block 302 and connected to the limit groove 101; wherein, a cross groove 3031 and a T-shaped groove 3032 are sequentially provided inside the limit block 303; wherein, a fan-shaped engaging right-angle groove is provided at the connection between the arc block 302 and the limit block 303; The protruding block 304 is fixed to the end of the limiting block 303; a plurality of engaging blocks A are arranged on the side of the engaging protruding block 304 relatively close to the rotating shaft 301; wherein, a plurality of engaging blocks A are arranged in a linear and equidistant order and extend into the cross groove 3031; the present invention uses the setting of the T-shaped groove 3032 to enable the protective block 4 to be engaged with the arc block 302 and the limiting block 303, so as to further improve the connection strength between the protective block 4 and the lock buckle 3, and at the same time, cooperate with the setting of the cross groove 3031, so that the limiting block 303 and the engaging protruding block 304 can be adapted and overlapped with the driving gear 5 in the locked state.

[0031] Furthermore, the meshing block A located relatively on the surface of the meshing protrusion 304 is shaped to be small at both ends and large in the middle. The present invention provides a meshing block A on the surface of the meshing protrusion 304 with a small end and a large middle end. When the lock catch 3 rotates, the meshing protrusion 304 enters the offset groove 1011 and contacts the tooth groove of the driving gear 5, thereby providing auxiliary guidance. This allows the meshing block A to quickly and easily re-engage with the driving gear 5. At the same time, the larger middle end is used to stably maintain a high-strength and stable meshing state between the meshing block A and the driving gear 5.

[0032] It is worth noting that the surfaces on both sides of the protective block 4 are in the shape of an arc with one end larger than the other end; and, the protective block 4 has an arc-shaped groove 401 that is adapted to the arc block 302 and the rotating shaft 301 on the side relatively close to the arc block 302 and the rotating shaft 301, so that the arc block 302 and the protective block 4 are tightly fitted when the lock buckle 3 and the lock body 1 are locked; wherein, the protective block 4 is provided with an adaptation groove 402 relative to the central axis of the arc block 302, wherein a forked sliding block 403 is provided at the small head end of the protective block 4; wherein, the sliding block 403 is slidably matched with the T-slot 3032; and, an engaging block B is provided between the two forked protrusions of the sliding block 403; wherein, a limiting guide block 404 is provided at the position of the protective block 4 relative to the auxiliary guide groove 1021. The present invention uses the arc shape of the surfaces of both sides of the protective block 4 to assist in dislocation when facing theft tools such as crowbars. At the same time, the protective block 4 is configured to be larger at one end and smaller at the other end to adapt to the basic work of the lock buckle 3 component. The large end of the protective block 4 is wrapped around the rotating shaft 301, so that the rotating shaft 301 can be basically rotated and disassembled in the unlocked state. The small end of the protective block 4 can be fully slidably engaged in the T-shaped groove 3032 to be rigidly connected with the arc block 302 and the limit block 303, and in the unlocked state, the conventional basic J-shaped setting of the lock buckle 3 is used to make the limit block 303 separate from the small end of the protective block 4, so as to realize the normal rotation and disassembly of the lock buckle 3, and the arc groove 401 is used to limit the protective block 4 relative to the outer surface of the lock buckle 3 in the locked state, so as to further improve the rigid connection strength of the protective block 4 in the locked state and enhance the anti-theft performance of violent demolition.

[0033] It is worth noting that the engaging protrusion 304 and the limiting block 303 are engaged with the driving gear 5 through the engaging block A.

[0034] Furthermore, the drive gear 5 is meshed with the meshing block B, resulting in a counter-rotating transmission structure between the lock catch 3, the protective block 4, and the drive gear 5. The present invention utilizes the drive gear 5, combined with a manual adjustment mechanism, to allow the lock catch 3 to synchronously control the raising and lowering of the protective block 4 in both the extended and retracted states. In the locked state, the protective block 4 is restrained to prevent retraction, while the linkage improves operational convenience.

[0035] Working principle: A method for using a five-proof smart lock for outdoor equipment in a distribution network. The lock buckle 3 rotates around the rotating shaft 301, so that the limit block 303 and the engaging protrusion block 304 are separated from the dislocation groove 1011, and then Figure 1As shown, the lock buckle 3 is passed through the pin lock hole of the distribution cabinet; at the same time, it is ensured that the five-defense intelligent lock is in a vertical shape, and the bottom of the protective block 4 is in contact with the lock body 1. Then, the lock buckle 3 is rotated in the opposite direction to cause the engaging protrusion block 304 to pass through the dislocation groove 1011 again to the limit groove 101. At the same time, the engaging block A on the surface of the engaging protrusion block 304 is set to be small at both ends and large at the middle end. When the lock buckle 3 rotates, the engaging protrusion block 304 enters the dislocation groove 1011 and contacts the tooth groove of the driving gear 5, which plays an auxiliary guiding role. Then, by manually pressing the lock buckle 3, the locking groove 3011 is locked with the lock pin in the five-defense intelligent lock core module 2. At the same time, the driving gear 5 is rotated by the engaging protrusion block 304 and several engaging blocks A, and the protective block 4 is driven to rotate synchronously. Figure 1 As shown, the pins of the distribution cabinet are moved closer and filled into the protective cavity to form an explosion-proof and pry-proof effect.

[0036] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
