[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Embodiment one

[0022] Please refer to Figures 1 to 4 The utility model provides a technical scheme: a safety unlocking device for tire durability test, including detection chamber 1, detection chamber 1 is specially used for detecting tire durability, the front side of detection chamber 1 is rotatably connected with two door plates 2, and the design of door plate 2 is to close detection chamber 1, and the inside of two door plates 2 is provided with the unlocking mechanism 3 for unlocking door plate 2.

[0023] Each unlocking mechanism 3 includes an electric push rod 301, a drive plate 302, a sliding groove 303, and two drive columns 304. The electric push rod 301 is located inside the door panel 2. The electric push rod 301 is designed to push the drive plate 302. The drive plate 302 is installed at the drive end of the electric push rod 301. The drive plate 302 is designed to cooperate with the sliding groove 303 to drive the drive columns 304, thereby driving the fixed column 305. The two sliding grooves 303 are opened inside the drive plate 302. The sliding grooves 303 are designed to drive the drive columns 304. The outer sides of the two drive columns 304 are slidably connected to the inside of the sliding grooves 303. The drive columns 304 are designed to facilitate the drive plate 302 to be driven by the sliding grooves 303 when it is driven, thereby driving the fixed column 305. Two drive columns 304 are fixedly connected to fixed columns 305 on their outer sides. The fixed columns 305 are designed to lock the door panel 2 inside the detection chamber 1. A timer 306 is installed inside the door panel 2. The timer 306 is designed to calculate time. Once the time exceeds 25 minutes, the timer 306 will control the unlocking mechanism 3, causing the unlocking mechanism 3 to drive the drive plate 302. A sound collector 307 is installed inside the door panel 2. The sound collector 307 is designed to detect the sound of a tire exploding inside the detection chamber 1. When the sound of a tire exploding inside the detection chamber 1 is detected, the unlocking mechanism 3 is activated, causing the unlocking mechanism 3 to drive the drive plate 302.

[0024] The outer side of the drive plate 302 is slidably connected to the inside of the door panel 2. The drive plate 302 is designed to cooperate with the sliding groove 303 to drive the drive column 304, so that the drive column 304 can drive the fixed column 305.

[0025] The timer 306 is connected to the electric actuator 301. The timer 306 is designed to activate the electric actuator 301 after 25 minutes.

[0026] The sound collector 307 is connected to the electric push rod 301. The sound collector 307 is designed to collect the sound of tire explosions in the detection chamber 1 before activating the electric push rod 301.

[0027] The outer sides of the two fixing posts 305 are slidably connected to the inside of the door panel 2 and the inside of the testing chamber 1. The fixing posts 305 are designed to fix the door panel 2 and the testing chamber 1 together. The worker sends the tire to be tested into the testing chamber 1 and the testing chamber 1 performs a durability test on the tire. After 25 minutes of tire testing, the tire is at a higher risk, as it could burst at any time during this period, causing injury to personnel. Therefore, the tire needs to be removed after 25 minutes. At this time, the door panel 2 is closed to the testing chamber 1. The waiting time after the tire durability test is 25 minutes. During the 25 minutes, if no tire burst sound is detected by the sound collector 307, the timer 306 will activate the electric push rod 301. The electric push rod 301 will activate the drive plate 302. The driven plate 302 will drive the drive post 304 through the sliding groove 303, thereby driving the fixing post 305, allowing the fixing post 305 to leave the inside of the testing chamber 1. At this time, the door panel 2 can be opened, and the indicator light 4 will activate. The system will change from "No Entry" to "Entry Allowed," allowing workers to remove the tire from the testing chamber 1. However, if the tire blows out before the 25-minute countdown, the sound collector 307 will detect the blowout and send the signal to the timer 306, resetting the timer and activating the electric push rod 301. This push rod 301 then drives the drive plate 302, which in turn drives the drive column 304 and the fixing column 305 via the sliding groove 303. The fixing column 305 then unlocks the door panel 2 from the testing chamber 1. At this point, the indicator light 4 will change from "No Entry" to "Entry Allowed," allowing the door panel 2 to be opened and the blown tire removed. Using a safety unlocking device for tire durability testing to lock and unlock the door panel 2 effectively prevents employees from touching the tire within 25 minutes after the test. This measure aims to prevent sudden tire blowouts during testing, reduce accidents caused by employee negligence, and improve overall safety.

[0028] Example 2

[0029] The top of the testing chamber 1 is equipped with an indicator light 4, which displays a 25-minute countdown to remind the workers.
