[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 2The diagram shows a safety railing for the top of an oil tanker truck with anti-theft functionality. It includes a tank body 1, a ladder 2 fixedly installed at one end of the tank body 1, a manhole cover 3 fixedly installed on the top of the tank body 1, and multiple railings 4 on the top of the tank body 1. Each railing 4 has an insertable mounting component 5, which is threadedly fixed to the top of the tank body 1. A locking assembly is also included to lock the railings 4 in place. The locking assembly is connected to the tank body 1 and the railings 4, and a convex crossbar is fixedly connected inside each railing 4. 6. A convex crossbar 6 is set on the top of the manhole cover 3. A baffle 7 is fixedly connected to the outer wall of the guardrail 4 near the ladder 2. The baffle 7 is set on the top of the other guardrails 4. By setting the baffle 7, when the guardrail 4 fixedly connected to the baffle 7 is locked, the other guardrails 4 are fixed. After the guardrail 4 fixedly connected to the baffle 7 is opened and locked, multiple guardrails 4 can be rotated and opened in sequence, avoiding the guardrails 4 being too long, which would make it difficult for workers to lift them, and facilitating the transportation of the guardrails 4 after production.

[0016] like Figures 3 to 4 As shown, the locking assembly includes a connector 8 fixedly connected to the outer wall of the guardrail 4. A gas spring 9 is rotatably hinged to the outer wall of the connector 8. The end of the gas spring 9 away from the connector 8 is hinged to the top of the tank body 1. A disguised button 10 is inserted inside the gas spring 9. By setting the disguised button 10, the appearance of the locking assembly is disguised, forming a disguised switch. This prevents thieves from knowing the location of the lock assembly's switch by observation. However, staff who know the location of the lock assembly's switch can open the locking assembly simply by pressing the disguised button 10, ensuring that staff can quickly open the locking assembly. A plug 11 is fixedly connected to one side of the disguised button 10. The plug 11 is slidably connected inside the connector 8. The disguised button 10 and the connector 8... A return spring 12 is provided between the two parts, and the return spring 12 is sleeved on the outer wall of the insert block 11. A rotating part 13 is rotatably connected inside the connector 8. A sliding part 14 is rotatably connected to the outer wall of the rotating part 13. A locking block 15 is slidably connected inside the connector 8. A groove 16 is opened on the outer wall of the locking block 15. The end of the sliding part 14 away from the rotating part 13 is slidably connected to one side of the insert block 11. The rotating part 13 is inserted into the inside of the groove 16. A locking groove 17 is opened on the inner wall of the top of the tank body 1. The locking block 15 is inserted into the inside of the locking groove 17. It should be noted that only the connector 8 closest to the ladder 2 on the guardrail 4 is installed with the locking assembly. The connectors 8 on the remaining guardrails 4 are conventionally set.

[0017] Working principle: When the staff needs to erect the guardrail 4 for safety protection, the staff first presses the disguise button 10, which compresses the return spring 12 and drives the insert block 11 to insert into the connector 8. Then, the insert block 11 drives the sliding part 14 to push the rotating part 13 to rotate. The rotating part 13 drives the locking block 15 to disengage from the locking groove 17 through the sliding groove 16. The locking block 15 stops the fixed limit between the locking groove 17 and the connector 8, and the locking between the tank body 1 and the guardrail 4 is released. The staff can lift the guardrail 4, which is no longer locked, until the guardrail 4 is upright. At this time, the gas spring 9 supports the guardrail 4 through the connector 8. The guardrail 4 can protect the staff from the top of the tank body 1 and prevent the staff from slipping from the top of the tank body 1 and causing a safety accident. It should be noted that when the staff stops pressing the disguise button 10, the return spring 12 will push the disguise button 10 to reset, and the return spring 12 will drive the rest of the components to reset. When the staff needs to retract the guardrail 4, the support of the gas spring 9 on the guardrail 4 is removed, allowing the guardrail 4 to rotate and reset. Due to the overall shape of the locking block 15, when the locking block 15 is lowered by the guardrail 4 through the connector 8, the inclined surface of the locking block 15 will contact the inner wall of the top of the tank 1. The locking block 15 is then pressed into the interior of the connector 8 by the inner wall of the top of the tank 1 through the inclined surface. Only after the guardrail 4 is fully retracted and the locking block 15 is aligned with the locking groove 17 can it be reset and inserted into the locking groove 17 to lock and fix the guardrail 4. At this time, the convex crossbar 6 on the guardrail 4 will press against the top of the manhole cover 3, preventing the manhole cover 3 from being opened at will and preventing thieves from stealing the oil inside the tank 1, thus achieving the anti-theft effect.
