[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-5The utility model provides a technical solution: a lightweight cab enclosure, including a back panel 1, a protective door 2, a guardrail 3 and a locking pin 4. The back panel 1 is installed on the back of the cab, and the protective door 2 is rotatably installed on one side of the back panel 1 and is arranged at a right angle to the back panel 1. A guardrail 3 is provided on one side of the protective door 2, and the guardrail 3 is installed on the side of the cab. A mounting opening 5 is opened on the inner side of the guardrail 3, and the locking pin 4 is movably inserted into the mounting opening 5. A locking opening 6 for cooperating with the locking pin 4 is opened on the side of the protective door 2. The back panel 1 and the protective door 2 both include a metal outer frame 7 and a crossbeam 8 installed in the middle of the metal outer frame 7. The inner side of the crossbeam 8 is processed and formed with a socket 9. Tempered glass 10 is inserted into the opening 9, and the end of the tempered glass 10 is located on the beam 8. Three groups of notches 11 are evenly opened on the surface of the beam 8, and movable openings 12 are opened on the upper and lower parts. The inner ends of the two adjacent groups of movable openings 12 are connected to the notch 11, and a rotary locking disk 13 is provided in the notch 11. A traction line 14 is connected between the three groups of rotary locking disks 13, and the end of the traction line 14 is connected to a limiting disk 15. An embedded opening 16 is opened on the edge of the beam 8, and a number of groups of limiting holes 17 are evenly opened inside the embedded opening 16. The limiting disk 15 is rotatably set in the embedded opening 16 and a positioning pin 18 is inserted on the surface, and the positioning pin 18 is inserted in the limiting hole 17.

[0021] Further improvement, such as Figure 2 As shown, the rotary locking disk 13 includes a rotating disk 19, a torsion spring 20 and a baffle 21. The rotating disk 19 is rotatably arranged in the slot 11 and the inner end is connected to the inner wall of the slot 11 through the torsion spring 20. The baffle 21 is divided into two groups and is symmetrically installed on the rotating disk 19 up and down. When the baffle 21 is in a vertical state, it contacts the tempered glass 10. When the baffle 21 is in a vertical state, the torsion spring 20 reaches the maximum torsion.

[0022] Further improvement, such as Figure 3 As shown, a connecting rod 22 is fixed to the surface of the rotating disk 19, and the traction line 14 is connected to the connecting rod 22 to facilitate traction adjustment.

[0023] Further improvement, such as Figure 3 As shown, several groups of rotating locking disks 13 have the same angle and are connected by traction lines 14, which can synchronously drive the groups of rotating locking disks 13 to rotate.

[0024] Specifically, the limit plate 15 includes a plate body 23 and a handle 24 installed on the plate body 23. The plate body 23 is rotatably set in the embedded opening 16, and the handle 24 is eccentrically set on the plate body 23. When the broken tempered glass needs to be replaced and installed, the staff can hold the handle 24 and drive the plate body 23 to rotate. During the rotation process, the plate body 23 pulls the rotating locking plate 13 through the traction line 14 to rotate synchronously, so that the baffle 21 is rotated into the movable opening 12. At this time, the tempered glass 10 can be disassembled and replaced. After the processing is completed, the baffle 21 can be reset and re-locked.

[0025] During use: When the tempered glass 10 is damaged, the staff can hold the handle 24 and drive the disc 23 to rotate. During the rotation process, the disc 23 pulls the rotating locking disc 13 through the traction line 14 to rotate synchronously. Under the action of the torsion spring 20, the baffle 21 is rotated into the movable opening 12. At this time, the tempered glass 10 can be disassembled and replaced. After the processing is completed, the baffle 21 can be reset, and finally the positioning pin 18 is inserted into the corresponding positioning hole 17 to achieve the purpose of re-locking. This design method is convenient for quick and tool-free replacement of tempered glass.
