Description

Technical Field

[0001] This utility model relates to the field of diesel engine technology, and in particular to a diesel engine with a protective structure. Background Technology

[0002] Diesel engines have good thermal efficiency and economy. Diesel engines use compressed air to raise the air temperature above the auto-ignition point of diesel fuel. When diesel fuel is injected, the diesel spray mixes with the air and ignites itself. Therefore, diesel engines do not require an ignition system. At the same time, the fuel supply system of diesel engines is also relatively simple.

[0003] Therefore, diesel engines are more reliable than gasoline engines. Because they are not limited by detonation and do not require diesel to spontaneously combust, diesel engines have a high compression ratio, and their thermal efficiency and economy are better than those of gasoline engines. At the same time, under the same power conditions, diesel engines have higher torque and lower speed at maximum power.

[0004] A search of existing Chinese patent technology reveals a "low-noise diesel engine" with publication number "CN212508546U". This device supports and fixes the diesel engine's cylinder block and related internal structures on a mounting base inside a muffler box. It uses a vacuum machine to extract gas from the vacuum chamber through a vacuum extraction pipe to create a vacuum, which effectively reduces noise leakage. However, the device's structure can easily cause the diesel engine's center of gravity to shift. During transport, this shift in center of gravity can cause the diesel engine to tilt or even tip over. The tilted diesel engine's internal structure is affected, resulting in poor performance after transport. Utility Model Content

[0005] Therefore, it is necessary to address the problem that when a diesel engine tilts or even tipes over during transportation, the internal structure of the tilted diesel engine is affected, resulting in poor performance after transportation. The solution is to provide a diesel engine with a protective structure, comprising: a connecting housing, the upper end of which is connected to a fuel tank; and a positioning mechanism installed at the lower end of the connecting housing. The positioning mechanism includes two connecting components connected to the lower end of the connecting housing, with a positioning component at the lower end of each connecting component extending into the interior of the positioning component, and one end of the positioning component extending below the fuel tank.

[0006] In one embodiment, the connecting assembly includes a support frame fixedly connected to the lower end of the connecting housing. A sliding strip is connected to the lower end of the support frame. Side sliding grooves are provided on both sides of the sliding strip. Two through holes are provided at the upper end of the support frame, extending through to the lower end of the support frame. A threaded hole is provided at the upper end of the sliding strip. A positioning bolt is provided inside the support frame.

[0007] In one embodiment, the positioning component includes two connecting rails, the upper end of the connecting rails is provided with a slide rail, the inner wall of the slide rail is slidably connected to the surface of the slide bar, two guide bars are fixedly connected to the inner wall of the connecting rails, the surface of the guide bars is slidably connected to the inner wall of the adjacent side slide groove, and side holes are provided on both sides of the connecting rails.

[0008] In one embodiment, the lower end of the positioning bolt passes through the adjacent through hole and extends into the interior of the adjacent threaded hole, and the surface of the positioning bolt is threaded to the inner wall of the adjacent threaded hole.

[0009] In one embodiment, a plurality of reinforcing ribs are fixedly connected to the inner side of the support frame, and the plurality of reinforcing ribs are evenly distributed along the inner bottom wall of the support frame.

[0010] In one embodiment, a positioning block is provided at the lower end of the guide strip, the positioning block is slidably connected to the inner wall of the slide, and a wave groove is provided at the upper end of the positioning block.

[0011] In one embodiment, a threaded rod is engaged at the upper end of the positioning block. The threaded rod is located inside the adjacent side hole, and a nut is threaded onto the surface of the threaded rod. The corrugated groove above the positioning block, combined with the surface curvature of the threaded rod, prevents the positioning block from easily sliding against the inner bottom wall of the slide.

[0012] Beneficial effects

[0013] The aforementioned diesel engine with a protective structure can provide good extended support for the connecting housing and fuel tank assembly through the positioning mechanism. The connecting component in this device can provide a good connection to the lower end of the connecting housing, and the positioning component can provide a good positioning function for the connecting component. By adjusting the position of the connecting component to the positioning component, the tilting of the connecting housing during transportation is reduced, the impact on the diesel engine during transportation is reduced, and the performance of the diesel engine after transportation is guaranteed.

[0014] The device, through its positioning components, can limit the position of the sliding bar inside the slide rail by the action of the wave groove above the positioning block and the surface curvature of the threaded rod. By turning the two nuts along the threaded surface of the threaded rod until it is in contact with the side of the adjacent connecting rail, the threaded rod will not easily move, thus maintaining the stable positioning function of the positioning block at the end of the sliding bar.

[0027] The following is combined Figures 1-4 This invention describes a diesel engine with a protective structure.

[0028] In one embodiment, a diesel engine with a protective structure includes: a connecting housing 1, with a fuel tank 2 connected to the upper end of the connecting housing 1; and a positioning mechanism 3, which is installed at the lower end of the connecting housing 1. The positioning mechanism 3 includes two connecting components 31 connected to the lower end of the connecting housing 1, with a positioning component 32 disposed at the lower end of the connecting components 31. The lower end of the connecting components 31 extends into the interior of the positioning component 32, and one end of the positioning component 32 extends below the fuel tank 2.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, the connecting assembly 31 includes a support frame 311 fixedly connected to the lower end of the connecting housing 1. A sliding strip 312 is connected to the lower end of the support frame 311. Side sliding grooves 313 are provided on both sides of the sliding strip 312. Two through holes 315 are provided at the upper end of the support frame 311, and the through holes 315 extend to the lower end of the support frame 311. A threaded hole 316 is provided at the upper end of the sliding strip 312. A positioning bolt 317 is provided inside the support frame 311. The lower end of the positioning bolt 317 passes through the adjacent through hole 315 and extends into the interior of the adjacent threaded hole 316. The surface of the positioning bolt 317 is threadedly connected to the inner wall of the adjacent threaded hole 316. Multiple reinforcing ribs 314 are fixedly connected to the inner side of the support frame 311. The multiple reinforcing ribs 314 are evenly distributed along the inner bottom wall of the support frame 311.

[0030] In this embodiment, the device can form a stable connection between the connecting housing 1 and the support frame 311 and the bolts. The reinforcing rib 314 can increase the support stability. The positioning bolt 317 passes through the lower through hole 315 and enters the interior of the threaded hole 316. The threaded connection between the threaded hole 316 and the positioning bolt 317 forms a tight connection between the support frame 311 and the sliding bar 312.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the positioning component 32 includes two connecting rails 321. The upper end of the connecting rail 321 is provided with a slide rail 322. The inner wall of the slide rail 322 is slidably connected to the surface of the sliding strip 312. The inner wall of the connecting rail 321 is fixedly connected with two guide strips 323. The surface of the guide strips 323 is slidably connected to the inner wall of the adjacent side slide groove 313. Side holes 324 are provided on both sides of the connecting rail 321. A positioning block 326 is provided at the lower end of the guide strip 323. The positioning block 326 is slidably connected to the inner wall of the slide rail 322. A wave groove is provided at the upper end of the positioning block 326. A threaded rod 325 is engaged at the upper end of the positioning block 326. The threaded rod 325 is located inside the adjacent side hole 324. A nut 327 is threadedly connected to the surface of the threaded rod 325.

[0032] In this embodiment, the device can provide a relatively good positioning effect for the sliding bar 312 through the positioning block 326. Furthermore, the wave groove provided above the positioning block 326, in conjunction with the surface curvature of the threaded rod 325, restricts the positioning block 326 from easily sliding on the inner bottom wall of the slide rail 322, thus limiting the position of the sliding bar 312 inside the slide rail 322. By tightening the two nuts 327 along the threaded surface of the threaded rod 325 until it is in contact with and secured to the side of the adjacent connecting rail 321, the threaded rod 325 will not easily displace, thus maintaining a stable limiting effect for the positioning block 326 at the end of the sliding bar 312.

[0033] Working principle: The support frame 311, together with the bolts, forms a stable connection with the connecting housing 1. The reinforcing rib 314 increases the stability of the support. The positioning bolt 317 passes through the lower through hole 315 and enters the interior of the threaded hole 316. The threaded hole 316 and the positioning bolt 317 are threadedly connected. The support frame 311 and the sliding bar 312 form a tight connection. The positioning block 326 provides a relatively good positioning for the sliding bar 312. The wave groove provided on the top of the positioning block 326, together with the surface curvature of the threaded rod 325, restricts the positioning block 326 from easily sliding on the inner bottom wall of the slide rail 322, thus limiting the position of the sliding bar 312 inside the slide rail 322. The two nuts 327 are tightened along the threaded knob on the surface of the threaded rod 325 and fit against the side of the adjacent connecting rail 321, keeping the positioning block 326 at the end of the sliding bar 312 in a stable limiting position.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
