[0036] The following reference Figures 1 to 3 The tractor hood hinge mechanism described in the embodiments of this application is illustrated.
[0037] See Figures 1 to 3As shown, an embodiment of this application provides a hinge mechanism for a tractor hood. This hinge mechanism includes an upper hinge seat 1, a rotating shaft 3, a lower hinge seat 2, a locking member 7, and an operating handle 8. One of the upper hinge seat 1 and the lower hinge seat 2 is used to connect to the tractor hood, and the other is used to connect to a designated position on the tractor. The upper hinge seat 1 includes a first body portion and a connecting bushing 101 disposed on the first body portion. Preferably, the connecting bushing 101 and the first body portion have an integral structure. The rotating shaft 3 passes through the interior of the connecting bushing 101, and the length of the rotating shaft 3 is greater than the length of the connecting bushing 101, such that both ends of the rotating shaft 3 protrude relative to the two end ports of the connecting bushing 101. The lower hinge seat 2 includes a second body part and a first connecting part 201 and a second connecting part 202 disposed on the second body part. The first connecting part 201 and the second connecting part 202 are symmetrically arranged at intervals. Preferably, the first connecting part 201, the second connecting part 202 and the second body part have an integral structure. One end of the rotating shaft 3 is detachably connected to the first connecting part 201, and the other end of the rotating shaft 3 is detachably connected to the second connecting part 202. Locking member 7 is disposed on the first connecting part 201 and / or the second connecting part 202. Locking member 7 can be detachably connected to operating handle 8 so that operating handle 8 can be locked or unlocked with locking member 7. The number of locking members 7 is the same as the number of operating handles 8. The end of rotating shaft 3 passes through the first connecting part 201 and the second connecting part 202. Operating handle 8 is disposed on the end of rotating shaft 3. It should be noted that at least one end of rotating shaft 3 is provided with operating handle 8. When locking member 7 is detachably disposed on both the first connecting part 201 and the second connecting part 202, operating handle 8 is disposed on both ends of rotating shaft 3. By turning operating handle 8, rotating shaft 3 can be driven to rotate.
[0038] Specifically, one end of the rotating shaft 3 is the first end 301, and the other end of the rotating shaft 3 is the second end. The shape of the first end 301 is the same as that of the second end. The cross-section of the first end 301 and the cross-section of the second end are rectangular or racetrack-shaped, preferably racetrack-shaped, so that the cross-section of the first end 301 and the cross-section of the second end both have a major diameter and a minor diameter.
[0039] Furthermore, the structure of the first connecting part 201 is the same as that of the second connecting part 202. Taking the first connecting part 201 as an example, the first connecting part 201 is plate-shaped and has a first snap-fit part for the first end 301 to pass through. Specifically, the first snap-fit part is a hole structure that passes through both sides of the plate surface of the first connecting part 201. A first latch 203 is provided on the upper side of the first latch 203. The diameter of the first latch 203 is smaller than the inner diameter of the first latch 301. The diameter of the first latch 203 is smaller than the major diameter of the first end 301 but larger than the minor diameter of the first end 301. After the rotating shaft 3 rotates a certain angle, it can enter the first snap-fit part through the first latch 203 or move out of the first snap-fit part to realize the installation or removal of the rotating shaft 3. Preferably, the rotation angle for installation and removal of the rotating shaft 3 is 90°. The connection and removal process between the second connecting part 202 and the second end is the same, which can be fully understood by those skilled in the art, and will not be described in detail here.
[0040] Furthermore, the locking member 7 is specifically a bolt. The locking member 7 passes through the first connecting part 201 and is threadedly connected to the first connecting part 201. One end of the bolt with an end cap is located on the inner wall surface of the first connecting part 201, and the other end of the bolt is located on the outer wall surface of the first connecting part 201 to form a locking part 701.
[0041] Furthermore, the operating handle 8 includes a fixed connection part 801 and a locking part 802. The fixed connection part 801 is plate-shaped and is fixedly connected to the end face of the rotating shaft 3. The connection method can be, but is not limited to, welding. The notch formed by the partial absence of the fixed connection part 801 is the locking part 802. The shape of the locking part 802 is adapted to the shape of the locking part 701.
[0042] The operating handle 8 also includes an operating part 803, which is plate-shaped and disposed on the edge of the fixed connection part 801. Preferably, the operating part 803 and the fixed connection part 801 have an integral structure. More preferably, the operating part 803 and the fixed connection part 801 are arranged at an angle. The operating part 803 can be used as a force application position. By rotating the operating part 803, the operating handle 8 can drive the rotating shaft 3 to rotate. As the operating handle 8 rotates, the locking part 802 can engage with the locking part 701 to lock, or the locking part 802 can separate from the locking part 701 to unlock. When the locking part 802 and the locking part 701 are unlocked, the first end 301 can be moved out of the first slot 203, and the second end can be moved out of the second slot, so that the rotating shaft 3 and the upper hinge seat 1 and the lower hinge seat 2 can be separated.
[0043] Furthermore, the hinge mechanism for the tractor hood also includes a nylon sleeve 6, which is fitted onto the shaft 3 and is located between the connecting bushing 101 and the shaft 3 to increase the lubrication effect between the shaft 3 and the connecting bushing 101.
[0044] Furthermore, the hinge mechanism for the tractor hood also includes a retaining ring 4 and a washer 5. The retaining ring 4 is a common shaft retaining ring in the prior art. The first end 301 and the second end are respectively fitted with retaining ring 4. A washer 5 is provided between the retaining ring 4 and the first end 301. Another washer 5 is provided between the retaining ring 4 and the second end to ensure the connection stability of the rotating shaft 3.
[0045] When installing the hinge mechanism for the tractor hood, after the first end 301 and the second end of the rotating shaft 3 are respectively installed in place with the first connecting part 201 and the second connecting part 202, the posture of the operating handle 8 is adjusted, and the locking part 7 is installed to lock the locking part 7 with the operating handle 8. At this time, the rotating shaft 3 is locked with the lower hinge seat 2, and the upper hinge seat 1 can rotate relative to the lower hinge seat 2 with the rotating shaft 3 as the pivot axis.
[0046] When disassembling the hinge mechanism of this tractor hood, remove the locking piece 7, rotate the operating handle 8 and the rotating shaft 3, with a rotation angle of 0 to 90°, separate the first end 301 from the first connecting part 201 and the second end from the second connecting part 202, and then remove the upper hinge seat 1 and the rotating shaft 3 from the lower hinge seat 2.
[0047] In summary, the tractor hood hinge mechanism provided in this application has a simple and novel structure, which can ensure the smooth relative rotation between the upper hinge seat 1 and the lower hinge seat 2, and can also lock and unlock the upper hinge seat 1 and the lower hinge seat 2. It can be easily installed and disassembled, effectively reducing the risk of damage to the tractor hood hinge mechanism during the disassembly and assembly process.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
