Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings and other embodiments can be obtained.

[0035] See Figure 1 , this embodiment discloses a cab, including a cab frame 1, a door 2, a half-opening device 3 and a door lock device 4. Taking the forward direction of the vehicle as the front side, the door 2 is hinged on the left and right sides of the cab frame 1. The half-opening device 3 is installed on the left cab frame 1. A door lock device 4 is installed at a position on the door 2 close to the half-opening device 3, and the door lock device 4 is arranged corresponding to the half-opening device 3. In this embodiment, the half-opening device 3 is arranged on the left side, so that the left door 2 can be half-opened. In other embodiments, according to actual needs, the half-opening device 3 can be arranged on the right side, or both sides can be arranged to meet the half-opening requirement of the door 2.

[0036] See Figure 2 and Figure 5 , the door lock device 4 is a prior art, including a housing 41 and a lock tongue 42 located inside the housing 41.

[0037] See Figure 3 and Figure 4 , the half-opening device 3 includes a fixed seat 31 fixed to the cab frame 1, a lock rod 313 arranged inside the fixed seat 31, and a support rod 32 rotatably connected to the fixed seat 31. The fixed seat 31 includes a seat body 311 fixed to the cab frame 1 and a mounting plate 312 fixed on the seat body 311 for mounting the support rod 32. The mounting plate 312 includes a vertical plate 3121 fixed to the seat body 311 and a horizontal plate 3122 horizontally extending outward from the middle of the vertical plate 3121.

[0038] The support rod 32 includes a body portion 321 and a rotating shaft portion 322 passing through the horizontal plate 3122. The rotating shaft portion 322 includes a support block 3221 connected to the body portion 321 and used for supporting on the mounting plate 312 and a rotating shaft 3222 vertically extending downward from the bottom of the support block 3221 and passing through the horizontal plate 3122. The support rod 32 can be locked on the horizontal plate 3122 by a locking nut 39 arranged at the bottom of the rotating shaft 3222 and can rotate freely through the rotating shaft 3222.

[0039] The body part 321 includes a support column 3211 fixed to the support block 3221 and a locking column 3212 bent and extending from the top end of the support column 3211. When the vehicle door 2 needs to be in a half-open state, open the vehicle door 2, rotate the support rod 32, rotate the locking column 3212 into the door lock device 4 and lock the locking column 3212 through the lock tongue 42, so that the support rod 32 supports the vehicle door 2.

[0040] See Figure 6 , a limit bolt 33 is vertically penetrated upwardly on the side of the transverse plate 3122 close to the front glass 11. A baffle 323 is provided below the support column 3211 and at the connection between the support column 3211 and the support block 3221. When the support rod 32 rotates, it abuts against the limit bolt 33 through the baffle 323 for limiting, preventing the rotation angle of the support rod 32 from being too large and causing the locking column 3212 to collide with the front glass 11 of the cab. At the same time, the baffle 323 also functions as a reinforcing rib to strengthen the connection between the body part 321 and the support block 3221. In other embodiments, other components vertically fixed on the transverse plate 3122 can be used to replace the limit bolt 33 to perform the limit function on the rotation of the support rod 32.

[0041] A first friction pad 34 is provided between the support block 3221 and the mounting plate 312, a second friction pad 35 is provided between the lock nut 39 and the mounting plate 312, and a lock washer 36 is provided between the second friction pad 35 and the lock nut 39. By adjusting the lock nut 39, the resistance of the support rod 32 to rotate can be changed.

[0042] A waist-shaped hole 3112 is formed on the side wall 3111 of the seat body 311 opposite to the front glass 11. The lock rod 313 passes through the waist-shaped hole 3112 and is locked to the fixed seat 31 through a first nut 37 and a second nut 38. The first nut 37 and the second nut 38 are respectively located on both sides of the side wall 3111, and a washer is provided between the second nut 38 and the side wall 3111. When the vehicle door 2 needs to be closed, close the vehicle door 2, so that the lock rod 313 is placed in the door lock device 4, and the lock rod 313 is locked through the lock tongue 42, thereby fixing the vehicle door 2 on the cab frame 1.

[0043] This embodiment also discloses a tractor, including the above-mentioned cab.

[0044] It is obvious to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations of the present invention falling within the scope of the appended claims and their equivalent technical solutions.
