[0030] The mounting frame 1 is mounted on the engineering machinery, and one end of the side cover door 3 is mounted on the mounting frame 1 through a hinge 4, so that the side cover door 3 is hinged on the mounting frame 1, and the side cover door 3 can be opened or closed around the hinge point;

[0031] The support assembly is installed between the mounting frame 1 and the side cover door 3, and is used to lock the side cover door 3 on the mounting frame 1 when the side cover door 3 is unfolded; wherein, the support assembly includes a support rod 2 and a slide member 7 installed on the side cover door 3, one end of the support rod 2 is movably installed on the mounting frame 1, and the other end is installed on the slide member 7, and the support rod 2 can slide along the slide member 7 and be locked after sliding into place.

[0032] As an improvement of the embodiment, Figure 3As shown, the slide member 7 is provided with a thin slide groove 72, and at least one end of the thin slide groove 72 is provided with a circular hole 71, and the aperture of the circular hole 71 is larger than the groove width of the thin slide groove 72. The thin slide groove 72 can realize a smoother sliding of the support rod 2, and the circular hole 71 can realize the positioning and locking of the support rod 2 after it slides into place. Preferably, both ends of the thin slide groove 72 are provided with circular holes 71, and the thin slide groove 72 is provided with circular holes 71 at both ends, so that the slide member 7 has universality and can simultaneously meet the installation and use requirements of the left and right cover doors.

[0033] As an improvement of the embodiment, Figure 3 , Figure 5 As shown, the slide member 7 is welded on the side cover door 3 along the length direction of the side cover door 3, and the structure is more stable. The support rod 2 slides in the slide member 7 to control the side cover door 3 to be opened or closed accordingly.

[0034] As an improvement of the embodiment, Figure 3 As shown, the support rod 2 includes a joint bearing 21 and an L-shaped rod body 23;

[0035] The spherical bearing 21 is mounted on the mounting frame 1 through a mounting nut 25, and is easy to assemble and disassemble;

[0036] One end of the L-shaped rod body 23 is connected to the joint bearing 21 through a thread, which is convenient for disassembly and assembly, and the other end is installed in the slide member 7 through a reducing structure. The reducing structure on the L-shaped rod body 23 and the gravity automatic centering method can realize the opening, closing and positioning of the side cover door 3.

[0037] As a further improvement of the embodiment, Figure 3 , Figure 4 As shown, an adjusting nut 22 is installed between the joint bearing 21 and the L-shaped rod body 23. Specifically, a threaded section 231 is provided at one end of the L-shaped rod body 23 close to the joint bearing 21, and the threaded section 231 is installed in the threaded hole of the joint bearing 21. At the same time, the adjusting nut 22 is installed on the threaded section 231 at a position close to the joint bearing 21, and the joint bearing 21 and the L-shaped rod body 23 are prevented from loosening by the adjusting nut 22.

[0038] As an improvement of the embodiment, Figure 3 , Figure 4 As shown, the variable diameter structure includes a limiting boss 232, a large diameter section 233 and a small diameter section 234 which are connected in sequence from top to bottom as an integral body;

[0039] The limiting boss is in a truncated cone shape, the diameter of the limiting boss 232 is greater than the diameter of the large diameter section 233 and greater than the diameter of the small diameter section 234, the upper part of the small diameter section 234 and the entire large diameter section 233 are both smooth in design, and the lower part of the small diameter section 234 is threadedly connected with a self-locking nut 24;

[0040] Specifically, a self-locking nut 24 is threadedly installed at the lower part of the small diameter section 234, so that the L-shaped rod body 23 is limitedly installed in the fine slide groove 72 of the slide groove member 7 and can slide along the fine slide groove 72. The smooth upper part of the small diameter section 234 can slide more smoothly and stably in the fine slide groove 72. When sliding to the circular holes 71 at both ends, the large diameter section 233 will automatically position itself in the circular hole 71 due to the deadweight of the variable diameter structure, so that the large diameter section 233 will not slide in the fine slide groove 72. At this time, axial limitation is achieved by the large diameter section 233, and radial limitation is achieved by the limiting boss 232, so that the L-shaped rod body 23 is positioned and connected in the circular hole 71 on the mounting frame 1 and the slide groove member 7, thereby realizing the positioning and locking of the side cover door 3 in the expanded state.

[0041] As an improvement of the embodiment, Figure 1-Figure 3 , Figure 5 As shown, one end of the side cover door 3 is mounted on the mounting frame 1 through a hinge 4 and a bolt 5, and the other end is mounted with a door lock 6. When the side cover door 3 is in a closed state, the side cover door 3 is locked on the mounting frame 1 through the door lock 6.

[0042] The specific usage process is as follows (taking the left cover door as an example):

[0043] When the side cover door 3 is in the closed state, the side cover door 3 is locked with the door lock 6 (such as Figure 2 );

[0044] When the side cover door 3 needs to be opened, after the door lock 6 is unlocked, the side cover door 3 is pushed open manually. At this time, the small diameter section 234 of the support rod 2 is in the fine slide groove 72 of the slide groove member 7, and slides with the rotation of the side cover door 3. When the side cover door 3 is pushed to a set angle (the side cover door 3 is in the unfolded state, such as Figure 5 As shown in the figure, at this time, the large diameter section 233 of the support rod 2 automatically falls into the circular hole 71 at the end of the fine slide groove 72 due to the effect of gravity. Since the diameter of the limiting boss 232 above the large diameter section 233 is greater than the diameter of the circular hole 71> the diameter of the large diameter section 233> the groove width of the fine slide groove 72> the diameter of the small diameter section 234, the large diameter section 233 cooperates with the limiting boss 232 above it and is limitedly installed in the circular hole 71. The limiting boss 232 can prevent it from falling from the circular hole 71, and the large diameter section 233 can prevent it from sliding along the fine slide groove 72. Relying on the variable diameter structure of the support rod 2, the side cover door 3 is self-locked at a set angle after being opened;

[0045] When the side cover door 3 needs to be closed, manual force is applied to push the large diameter section 233 of the support rod 2 out of the circular hole 71, and the side cover door 3 is closed at the same time. The small diameter section 234 of the support rod 2 slides in the fine slide groove 72, and after reaching the closed position (at a certain position in the fine slide groove 72), the door lock 6 is locked to achieve the closing of the side cover door 3.

[0046] The utility model discloses a side cover support mechanism for engineering machinery, wherein a support rod and a slide groove member are installed between a mounting frame and a side cover door, wherein one end of the support rod is movably connected to the mounting frame, and the other end slides on the slide groove member of the side cover door. When the support rod slides, the opening or closing process of the side cover door is smoother. When the support rod slides into place, it is locked on the slide groove member, thereby improving the practicality and reliability of the side cover door, having a low use cost, and avoiding the defect that the traditional side cover door support using a gas spring is easily affected by temperature.
