The two ends of the housing are respectively inserted with a transmission shaft and a corner shaft frame. A transmission gear is installed on the transmission shaft, and a corner gear is installed on the corner shaft frame. A transmission shaft rotatably connected to the housing is provided inside the housing, and a transmission gear is installed on the transmission shaft. The drive gear, the transmission gear, and the corner gear are sequentially meshed for transmission. The corner shaft frame is rotatably connected to the transmission shaft. One end of the corner shaft frame extends out from an arc-shaped corner opening provided on the housing. An oil seal groove is provided outside the housing at the corner opening. An oil seal is installed in the oil seal groove. Slide rails are symmetrically installed at both ends outside the housing at the oil seal groove. The corner cover covers the upper ends of the oil seal and the corner opening. The two sides of the corner cover are slidably connected to the two slide rails. Bolt fixing seats are welded outside the housing at the slide rails. Limit bolts are installed on the bolt fixing seats, and pressing wheels are fixed on the limit bolts. The bottom end of the pressing wheel abuts against the top end of the corner cover.

[0005] Preferably, one end of the corner shaft frame passes through the inside of the corner cover.

[0006] Preferably, the opening angle of the corner opening is 0-180 degrees.

[0007] The present invention provides an assembly structure of a corner box. It has the following beneficial effects:

[0008] The assembly structure of the corner box provided by the present invention drives the corner cover to slide along the extension direction of the slide rail through the corner shaft frame, seals the lubricating oil inside the housing through the oil seal installed in the internal oil seal groove, and limits the corner cover through the pressing wheel on the external limit bolt to prevent oil leakage inside due to deformation of the corner cover, increasing the reliability of the corner. The opening angle of the corner opening is 0-180 degrees, enabling a wide-angle corner. Description of the Drawings

[0014] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "top", "bottom", "one side", "the other side", "front", "rear", "middle part", "inside", "top end", "bottom end", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention; the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; in addition, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0015] As Figures 1-3As shown in the figure, an assembly structure of a corner box includes a housing 1, a drive shaft 2, a transmission shaft 3, a corner shaft bracket 4, an oil seal 7, a corner cover 8, a slide rail 9, a bolt fixing seat 10, a limit bolt 11, a drive gear 12, a transmission gear 13, a corner gear 14 and a pressing wheel 15. The two ends of the housing 1 are respectively inserted with a transmission shaft 3 and a corner shaft bracket 4. A transmission gear 13 is installed on the transmission shaft 3, and a corner gear 14 is installed on the corner shaft bracket 4. The transmission shaft 3 rotatably connected to the housing 1 is provided with a transmission gear 13 on it. The drive gear 12, the transmission gear 13 and the corner gear 14 are engaged and transmitted in sequence. The corner shaft bracket 4 is rotatably connected to the transmission shaft 3. One end of the corner shaft bracket 4 extends out from an arc-shaped corner opening 5 provided on the housing 1. An oil seal groove 6 is provided on the outside of the housing 1 at the corner opening 5, and an oil seal 7 is installed in the oil seal groove 6. Slide rails 9 are symmetrically installed at both ends outside the oil seal groove 6 of the housing 1. The corner cover 8 covers the upper ends of the oil seal 7 and the corner opening 5. The two sides of the corner cover 8 are slidably connected to the two slide rails 9. A bolt fixing seat 10 is welded on the outside of the housing 1 at the slide rail 9. A limit bolt 11 is installed on the bolt fixing seat 10, and a pressing wheel 15 is fixed on the limit bolt 11. The bottom end of the pressing wheel 15 abuts against the top end of the corner cover 8.

[0016] Through the above technical solution of the present invention, one end of the corner shaft bracket 4 passes through the inside of the corner cover 8.

[0017] Through the above technical solution of the present invention, the opening angle of the corner opening 5 is 0 - 180 degrees, which can achieve a wide-angle corner.

[0018] Specifically, during use, the drive shaft 2 is driven to rotate by external power, which can be electric drive, vehicle transmission shaft drive or diesel engine drive. The drive shaft 2 drives the transmission gear 13 to rotate through the drive gear 12. The rotation of the transmission gear 13 drives the corner gear 14 to rotate, thereby driving the corner shaft bracket 4 to rotate along the transmission shaft 3 for cornering. The corner end passes through the corner opening 5 and the corner cover 8. The corner cover 8 is driven to slide along the extension direction of the slide rail by the corner shaft bracket 4. The lubricating oil inside the housing 1 is sealed by the oil seal 7 installed in the internal oil seal groove 6. The corner cover 8 is limited by the pressing wheel 15 on the external limit bolt 11 to prevent oil leakage inside due to the deformation of the corner cover 8, increasing the reliability of cornering. The opening angle of the corner opening 5 is 0 - 180 degrees, which can achieve a wide-angle corner.
