One end of each of the two second springs is fixedly connected to the same rectangular plate. A reserved hole is provided on the rectangular plate at the corresponding cutting blade, through which the cutting blade can pass.
[0016] The effect achieved by the above-mentioned components is as follows: when the driver pushes the protective plate outward, the top of the insert plate first contacts the rectangular plate, the insert plate squeezes the rectangular plate, the second spring contracts, at this time the cutting blade passes through the reserved hole of the rectangular plate, the cutting blade squeezes the insert plate, making the insert plate easy to break. When there is no external force, under the action of the second spring, the rectangular plate moves away from the cutting blade, avoiding contact between the cutting blade and the insert plate. The auxiliary device facilitates the breakage of the insert plate, thereby making it easier for the staff to open the installation hole and facilitate the staff to quickly rescue the personnel inside the mining truck cab.
[0017] Preferably, the rectangular plate has two limiting rods that slide through its surface, with both ends of the limiting rods fixedly connected to the inner wall of the groove.
[0018] The effect achieved by the above components is that by setting the limit rod, the direction of movement of the rectangular plate is restricted, thus preventing the rectangular plate from shaking.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] When the protective plate needs to be installed, the workers move two insert plates until they are fully inserted into the protective plate. At this point, the first spring is compressed. Finally, the workers insert the protective plate into the mounting hole in the truck cab. When the protective plate is in contact with the fixing frame, the insert plates enter the mounting hole in the truck cab under the return force of the first spring, thus fixing the protective plate in place. If the driver has an accident and the truck door cannot be opened, the driver or medical personnel can kick the protective plate, breaking the plastic insert plates on it. The medical personnel can then remove the protective plate and rescue the driver through the mounting hole. The protective device also provides safety for the driver when the doors and windows of the truck cab cannot be opened. Attached Figure Description

The mining truck cab 1 has an insertion hole 26 corresponding to the insert plate 24, wherein the size of the insert plate 24 is adapted to the size of the insertion hole 26, and the insert plate 24 is a plastic plate. A first spring 25 is fixedly connected at both ends to the inner walls of the insert plate 24 and the protective plate 22, respectively. The first spring 25 is in a relaxed state when the two insert plates 24 are far apart from each other. When the protective plate 22 needs to be installed, the workers move the two insert plates 24 until they are fully inserted into the interior of the protective plate 22. At this time, the first spring 25 is compressed. Finally, the workers insert the protective plate 22 into the mounting hole 21 of the mining truck cab 1. When the protective plate 22 is in contact with the fixing frame 23, under the action of the return force of the first spring 25, the insert plates 24 enter the insertion hole 26 of the mining truck cab 1, thus achieving the effect of fixing the protective plate 22. When the driver has an accident while driving the truck and the truck door cannot be opened, the driver or medical personnel kick the protective plate 22, and the plastic insert plates 24 on the protective plate 22 break. Finally, the medical personnel remove the protective plate 22 and rescue the driver through the mounting hole 21. When the doors and windows of the mining truck cab 1 cannot be opened, the medical personnel rescue the driver through the mounting hole 21, providing safety for the driver.
[0029] Reference Figure 1-5As shown, a sealing ring 27, which is a rubber ring, is fixedly connected to the upper surface of the fixed frame 23. The sealing ring 27 seals the gap between the protective plate 22 and the fixed frame 23, preventing rainwater from entering the interior of the mining truck cab 1. A pointed protrusion 28 is fixedly connected to one end of the insert plate 24, with the tip of the protrusion 28 away from the insert plate 24. The pointed protrusion 28 facilitates the insertion of the insert plate 24 into the insertion hole 26 of the mining truck cab 1, making it easier for workers to install the protective plate 22. A pull plate 29 is fixedly connected to the top of the insert plate 24, located on the outside of the protective plate 22, and its surface has anti-slip texture. The pull plate 29 increases the contact area between the worker's hand and the insert plate 24, thus facilitating the movement of the insert plate 24.
[0030] Reference Figure 1-5 As shown, the mining truck cab 1 is equipped with an auxiliary device 3 at the corresponding insertion hole 26. The auxiliary device 3 includes two cutting blades 31, which are located directly above the insertion plate 24.

The rectangular plate 33 has a reserved hole 34 at the corresponding cutting blade 31, through which the cutting blade 31 can pass. When the driver pushes the protective plate 22 outward, the top of the insert plate 24 first contacts the rectangular plate 33. The insert plate 24 presses against the rectangular plate 33, and the second spring 32 contracts. At this time, the cutting blade 31 passes through the reserved hole 34 of the rectangular plate 33 and presses against the insert plate 24, making it easy for the insert plate 24 to break. When there is no external force, under the action of the elastic force of the second spring 32, the rectangular plate 33 moves away from the cutting blade 31, avoiding contact between the cutting blade 31 and the insert plate 24. The auxiliary device 3 facilitates the breaking of the insert plate 24, which in turn makes it easier for the staff to open the installation hole 21 and facilitates the staff to quickly rescue the personnel inside the mining truck cab 1.
[0031] Reference Figure 1-5 As shown, two limiting rods 35 slide through the surface of the rectangular plate 33, with both ends of the limiting rods 35 fixedly connected to the inner wall of the groove. By setting the limiting rods 35, the movement direction of the rectangular plate 33 is restricted, preventing the rectangular plate 33 from shaking.
[0032] Working principle: When the protective plate 22 needs to be installed, the worker first moves the two insert plates 24 by pulling the plate 29. The two insert plates 24 are fully inserted into the interior of the protective plate 22. At this time, the first spring 25 is compressed. Finally, the worker sends the protective plate 22 into the mounting hole 21 of the mining truck cab 1. When the protective plate 22 is in contact with the sealing ring 27 on the fixing frame 23, under the action of the return elasticity of the first spring 25, the insert plates 24 enter the insertion hole 26 of the mining truck cab 1 with the help of the pointed protrusion 28, thus achieving the effect of fixing the protective plate 22. When the driver of the truck has an accident and the truck door cannot be opened, the driver or medical personnel kick the protective plate 22. The plastic insert plates 24 on the protective plate 22 break. Finally, the medical personnel remove the protective plate 22 and rescue the driver through the mounting hole 21. When the doors and windows of the mining truck cab 1 cannot be opened, the medical personnel rescue the driver through the mounting hole 21 through the protective device 2, providing safety for the driver.
[0033] When the driver pushes the protective plate 22 outward, the top of the insert plate 24 first contacts the rectangular plate 33. The insert plate 24 presses against the rectangular plate 33, and the second spring 32 contracts. At this time, the cutting blade 31 passes through the reserved hole 34 of the rectangular plate 33 and presses against the insert plate 24, making it easy for the insert plate 24 to break. When there is no external force, under the action of the elastic force of the second spring 32, the rectangular plate 33 moves away from the cutting blade 31, avoiding contact between the cutting blade 31 and the insert plate 24. The auxiliary device 3 facilitates the breaking of the insert plate 24, which in turn makes it easier for the staff to open the installation hole 21 and facilitates the staff to quickly rescue the personnel inside the mining truck cab 1.
