Description
Technical Field
[0001] The present invention relates to the technical field of distribution transformers, and particularly relates to an anti-theft linkage lock component for a distribution transformer. Background Art
[0002] A distribution transformer, abbreviated as "distribution transformer", is an important electrical device in a distribution system. A distribution transformer refers to a static electrical appliance used in a distribution system to transform AC voltage and current according to the law of electromagnetic induction and transmit AC electric energy. It can change an AC voltage (current) of a certain value into another or several AC voltages (currents) with the same frequency but different values, so as to meet the power consumption needs of different users;
[0003] However, there are still some problems in the use of traditional distribution transformers. A distribution transformer is an important part of power equipment, and its interior contains precious metals such as copper cores, and these metals have high economic value. Therefore, in order to seek personal gain, some lawbreakers will choose to steal distribution transformers to obtain the metal parts for resale. Many distribution transformers are located in special areas for agricultural drought resistance and drainage in the wild or remote corners, and these locations are relatively hidden and have less traffic, making it more difficult to detect theft. In addition, there may be insufficient monitoring and security measures in these locations, providing opportunities for thieves. Therefore, an anti-theft linkage lock component for a distribution transformer is needed to solve the above problems. Summary of the Invention

[0018] Furthermore, when the fixed rod is inserted into the fixed slot, the top end of the fixed rod will push the extrusion plate upward, and through cooperation with the connecting plate, push the shielding plate downward to block the lock port, making it difficult for thieves to find the position of the fixed rod when trying to pry the lock, thus realizing the anti-theft work.
[0019] 2. By providing an auxiliary structure, after the anti-theft linkage structure is locked, through the combined use of the gear ring and the shielding block, the second lock hole can be blocked to prevent thieves from damaging the second lock hole, and through the combined use of the limiting post and the limiting hole, only by inserting a matching key into the first lock hole can the limiting post be pushed out of the limiting hole to rotate the rotating core, causing the shielding block to move to one side to expose the second lock hole, thereby reducing the possibility of the anti-theft linkage structure being pried and further improving the anti-theft effect.

[0033] Refer to Figures 1 - 10As shown: The auxiliary structure 4 includes an installation box 401, the installation box 401 is installed at the top of the fixing frame 5, a rotating core 403 is movably installed inside the installation box 401, a first lock hole 4010 is opened inside the rotating core 403, a fixing sleeve 404 is installed on the outer side of one end of the rotating core 403, one end of the fixing sleeve 404 is fixed to one side inside the installation box 401, a first lock hole 4010 is opened inside the rotating core 403, a gear ring 409 is fixed to the outer side of the rotating core 403, a shielding block 402 is installed at the bottom end inside the installation box 401, an installation hole 405 is installed on one side inside the fixing sleeve 404, a telescopic spring 406 is installed on one side inside the installation hole 405, a limiting column 407 is fixed to one side of the telescopic spring 406, a limiting hole 408 is opened on one side inside the rotating core 403, the limiting column 407 is inserted into the inside of the limiting hole 408, a plurality of teeth are arranged at the top end of the shielding block 402, the shielding block 402 is meshed with the gear ring 409, the shielding block 402 is installed in the guiding groove at the bottom end of the installation box 401, and a guiding structure is formed between the shielding block 402 and the guiding groove at the bottom end of the installation box 401; one end of the telescopic spring 406 is fixed to one end of the limiting column 407, and a telescopic structure is formed between the telescopic spring 406 and the limiting column 407; the inner diameter of the limiting hole 408 is larger than the outer diameter of the limiting column 407, and an inserting structure is formed between the limiting hole 408 and the limiting column 407.
[0034] Specifically, in this embodiment, when using the distribution transformer 9, the distribution transformer 9 is installed inside the protective shell 1. After the installation is completed, the door 3 is locked. When locking, first insert the first key into the inside of the fixing groove 6010. At this time, when the matching key is inserted into the inside of the fixing groove 6010, the limiting column 407 will be pushed out from the inside of the limiting hole 408. After the limiting column 407 is pushed out, rotate the rotating core 403. When the rotating core 403 rotates, it will drive the shielding block 402 to move to one side through the gear ring 409, so as to expose the second lock hole 609. After the locking is completed, rotate the rotating core 403 in the reverse direction to make the shielding block 402 move back, and block the second lock hole 609 to prevent the second lock hole 609 from being found and damaged by thieves, improving the anti-theft effect, and thus completing the shielding work of the second lock hole 609.
[0035] Refer to Figures 1 - 10As shown in the figure: Fixing grooves 6010 are provided at the upper and lower ends inside the fixing block 601.

At this time, one side of the screw sleeve 605 is limited by the moving groove 608, driving the fixing rod 607 to move. When the fixing rod 607 moves to the position of the locking port 602, close the door 3 so that the fixing rod 607 is inserted into the locking port 602. When the fixing rod 607 is inserted into the locking port 602, then rotate the bidirectional screw 604 again to move the fixing rod 607 into the fixing groove 6010, completing the locking of the door 3, so that the door 3 cannot be easily opened without a key, and the distribution transformer 9 inside the protective shell 1 cannot be stolen by others, thus completing the anti-theft work. When the fixing rod 607 moves into the fixing groove 6010, the fixing rod 607 will push the extrusion plate 6014 upward. When the extrusion plate 6014 is pushed upward, one end of the connecting plate 603 will move upward and the other end will move downward. When one end of the connecting plate 603 moves upward, it will also pull the return spring 6013 to stretch. When the other end of the connecting plate 603 moves downward, it will push the shielding plate 6011 to be inserted into the front end of the locking port 602 to block the locking port 602, making it difficult for thieves to find the position of the fixing rod 607 when they want to pry off the fixing rod 607 to open the door 3, further improving the anti-theft effect, and thus completing the anti-theft work of the distribution transformer 9.
