[0010] Beneficial effects:

[0011] The present utility model provides an explosion-proof handheld terminal with a rear bracket, and has the following beneficial effects. Through its structural design, when it is necessary to support the terminal body, first rotate the first support located in the upper receiving groove. After the first support rotates along the slider to a certain angle, move the first support forcefully. The movement of the first support drives the locking device to move out from the positioning hole at the current position. At this time, continue to move the first support. The movement of the first support drives the slider to slide in the upper receiving groove.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: an explosion-proof handheld terminal with a rear bracket, including a terminal body 1, upper receiving grooves 2, sliders 3, first supports 4, locking devices 5, positioning holes 6, lower receiving grooves 7, connecting shafts 8, second supports 9, and elastic ropes 10. Two upper receiving grooves 2 are opened on the back of the terminal body 1. Each upper receiving groove 2 is slidably connected to a slider 3, and each slider 3 is rotatably connected to a first support 4. The first support 4 is located in the upper receiving groove 2. A locking device 5 is installed on the slider 3, and a locking device 5 is installed on the first support 4. Three positioning holes 6 are opened on each upper receiving groove 2. The positioning holes 6 on two of the upper receiving grooves 2 correspond to the locking devices 5 on the sliders 3, and the positioning holes 6 on the other upper receiving groove 2 correspond to the locking devices 5 on the first supports 4. A lower receiving groove 7 is opened on the back of the terminal body 1. The lower receiving groove 7 is rotatably connected to a connecting shaft 8, and the connecting shaft 8 is fixedly connected to a second support 9. A locking device 5 is installed on the second support 9. The second support 9 is located in the lower receiving groove 7. A positioning hole 6 is opened on the lower receiving groove 7, and the positioning hole 6 on the lower receiving groove 7 corresponds to the locking device 5 on the second support 9. One end of an elastic rope 10 is fixedly connected to the first support 4 and the other end is connected to the first support 4 through a magic tape. The other end of the other elastic rope 10 is fixedly connected to the second support 9 and the other end is connected to the second support 9 through a magic tape.

[0022] In the present utility model, the locking device 5 includes a positioning rod 501, a baffle 502, and a spring 503. The positioning rod 501 is fixedly connected to the slider 3, the baffle 502 is fixedly connected to the positioning rod 501, the baffle 502 is slidably connected to the slider 3, the spring 503 is located in the slider 3 and one end is fixedly connected to the slider 3, and the other end of the spring 503 is fixedly connected to the baffle 502. The end of the positioning rod 501 is inserted into the positioning hole 6. When the locking device 5 is driven to move, the arc at the end of the positioning rod 501 is pressured to slide out of the currently inserted positioning hole 6 and drive the baffle 502 to move. The movement of the baffle 502 squeezes the spring 503. When the positioning rod 501 is aligned with the positioning hole 6 again, the spring 503 will drive the baffle 502 to reset, and the reset of the baffle 502 drives the positioning rod 501 to be inserted into the positioning hole 6 at the current position for limiting.

[0023] In the present utility model, soft pads 11 are provided on both sides of the terminal body 1. The soft pads 11 are fixedly connected to the terminal body 1. The soft pads 11 on both sides of the terminal body 1 can improve the comfort of the staff when using the terminal body 1.

[0024] In the present utility model, grooves 12 are provided on the first support 4 and the second support 9. The groove 12 is formed on the first support 4, and the groove 12 is formed on the second support 9. The grooves 12 on the first support 4 and the second support 9 can facilitate the staff to turn the first support 4 or the second support 9 out of the upper receiving groove 2 or the lower receiving groove 7.

[0025] In the present utility model, the elastic rope 10 is located between the terminal body 1, the first support 4 and the second support 9. The elastic rope 10 located between the terminal body 1, the first support 4 and the second support 9 can be more conveniently stored in the upper receiving groove 2 and the lower receiving groove 7.

[0026] In this embodiment: When it is necessary to support the terminal body 1, first rotate the first support 4 located in the upper receiving groove 2. After the first support 4 rotates along the slider 3 to a certain angle, move the first support 4 forcefully. The movement of the first support 4 drives the locking device 5 to move out of the positioning hole 6 at the current position. At this time, continue to move the first support 4. The movement of the first support 4 drives the slider 3 to slide in the upper receiving groove 2. When the slider 3 slides to the lowest position, the locking device 5 on the slider 3 corresponds to the positioning hole 6 at the current position, limiting the slider 3. When the locking device 5 is driven to move, the arc at the end of the positioning rod 501 is pressured to slide out of the currently inserted positioning hole 6 and drives the baffle 502 to move. The movement of the baffle 502 squeezes the spring 503. When the positioning rod 501 aligns with the positioning hole 6 again, the spring 503 drives the baffle 502 to reset. The reset of the baffle 502 drives the positioning rod 501 to be inserted into the positioning hole 6 at the current position for limiting. After the first support 4 is adjusted, rotate the second support 9 located in the lower receiving groove 7. The rotation of the second support 9 drives the connecting shaft 8 to rotate in the lower receiving groove 7. When the first support 4 and the second support 9 both rotate to a certain angle, the terminal body 1 can be supported, thus liberating the hands of the staff and improving the work efficiency of the staff. The grooves 12 on the first support 4 and the second support 9 facilitate the staff to rotate the first support 4 or the second support 9 out of the upper receiving groove 2 or the lower receiving groove 7. When the staff carries the present utility model, move the first support 4 forcefully to move the locking device 5 out of the positioning hole 6 at the current position. At this time, continue to move the first support 4. The movement of the first support 4 drives the slider 3 to slide in the upper receiving groove 2. When the slider 3 slides to the highest position, the locking device 5 on the slider 3 corresponds to the positioning hole 6 at the current position, limiting the slider 3. Then rotate the first support 4 and the second support 9 to be perpendicular to the terminal body 1 respectively, and then pass the arms through the middle positions between the second support 9 and the first support 1 and tie the arms with the elastic rope 10. The other end of the elastic rope 10 is pasted on the first support 4 and the second support 9 through the magic tape, thereby fixing the terminal body 1 on the arm of the staff, facilitating the staff to carry. The soft pads 11 on both sides of the terminal body 1 can improve the comfort of the staff when using the terminal body 1.
