Technical Field
[0001] This utility model relates to the field of diesel engine technology, specifically to a small diesel engine that is easy to move. Background Technology
[0002] A diesel engine is an engine that burns diesel fuel to obtain energy. The advantages of a diesel engine are high power and good economic performance. Diesel engines are usually used in conjunction with generators, and the diesel engine is used as the prime mover to drive the generator to generate electricity.
[0003] For example, a portable small diesel engine with authorization announcement number CN213745559U includes a diesel engine bracket and a diesel engine mounted inside the bracket. One bottom end of the diesel engine bracket is rotatably mounted with variable rollers, and the other bottom end is fixed with a support foot. The variable rollers number two. However, this document still has shortcomings. In use, by including six variable rollers forming a circular arc plate on both sides of the diesel engine bracket, and a dual-axis motor between two variable rollers, the output end of the dual-axis motor is connected to a telescopic bracket that changes the diameter of the variable rollers. The telescopic bracket, driven by a dual-axis motor, extends or retracts, thereby changing the diameter of the variable roller. This allows it to adapt to different terrains. However, when the small diesel engine described in the above document travels over uneven surfaces, it will vibrate. Excessive vibration can damage the internal structure of the small diesel engine. Additionally, when the small diesel engine is parked on a sloping surface, excessive water or oil can easily lead to leakage. Furthermore, parking on a sloping surface makes it difficult to keep the small diesel engine in a level position. Utility Model Content
[0004] The purpose of this invention is to solve the problem of vibration caused by small diesel engines when passing over uneven roads, and to propose a small diesel engine that is easy to move.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] Design a small, portable diesel engine, including a base plate and a first bracket. The first bracket is fixedly connected to the bottom of the base plate and has a moving mechanism inside. A second bracket is fixedly connected to the bottom of the base plate and has a supporting mechanism inside. A first vertical plate is fixedly connected to the left side of the base plate, and two handrails are fixedly connected to the left side of the first vertical plate. The base plate has a groove inside.
[0007] Preferably, the moving mechanism includes a first slide rod, which is fixedly connected inside the first bracket. Two first sliders are slidably connected to the outer wall of the first slide rod. A spring is sleeved on the outer wall of the first slide rod, and the two ends of the spring are fixedly connected to the first bracket and the first slider, respectively. A first support rod is rotatably connected to the lower part of the first slider through a pin. The ends of the two first support rods are rotatably connected to a support plate through pins. Second support rods are fixedly connected to the front and rear surfaces of the support plate. The outer wall of the end of the second support rod is rotatably connected to a wheel through a bearing.
[0008] Preferably, the support mechanism includes a worm gear, the outer walls of both ends of which are rotatably connected to a second bracket via bearings. A rotating wheel is fixedly connected to the end of the worm gear, and the worm gear meshes with a worm wheel. The worm wheel is rotatably connected to the second bracket via bearings. A first connecting rod is fixedly connected to the surface of the worm wheel. A sliding groove provided in the first connecting rod is slidably connected to the outer wall of a pin. The pin is fixedly connected to the surface of a second connecting rod. The outer wall of the second connecting rod is slidably connected to a sleeve. The upper end of the sleeve is fixedly connected to a base plate, and a pad is fixedly connected to the lower end of the second connecting rod.
[0009] Preferably, the groove is clearance-fitted with the outer wall of the small diesel engine, and two second vertical plates are fixedly connected to the upper surface of the base plate.
[0010] Preferably, a threaded block is fixedly connected to the upper part of the second vertical plate, and a screw is internally threaded into the threaded block.
[0011] Preferably, the outer wall of the screw end is rotatably connected to a clamping plate via a bearing, and the clamping plate is in contact with the outer wall of the small diesel engine.
[0012] Preferably, a second slider is fixedly connected to the outer wall of the support plate, and the second slider is slidably connected to the outer wall of the second slide rod.
[0013] Preferably, the second slide bar is fixed inside the first bracket.
[0014] The present invention provides a portable small diesel engine with the following advantages: Through the cooperation of the first sliding rod, the first slider, the spring, the first support rod, the support plate, the second support rod, and the wheel, the wheel rolls on the ground. When the wheel passes over an uneven surface, the vertical position of the wheel changes, causing the wheel to move the second support rod, which in turn moves the support plate. The support plate then drives the two first support rods, which in turn drive the first slider. The first slider slides on the outer wall of the first sliding rod and compresses or stretches the spring. The spring buffers the force, preventing the wheel from bumping when passing over uneven surfaces. Consequently, the small diesel engine itself does not vibrate when moving on uneven surfaces, thus avoiding damage to the internal structure of the small diesel engine.
[0015] Through the cooperation of the worm, rotating wheel, worm gear, first connecting rod, pin, second connecting rod, sleeve, and pad, when the small diesel engine is parked on a sloping surface, the wheels are positioned on the higher side of the surface. Rotating the rotating wheels on both sides causes the worm to rotate, which in turn drives the worm gear to rotate. The worm gear then drives the first connecting rod to rotate. The first connecting rod drives the pin through an internal groove, which in turn drives the second connecting rod. The second connecting rod slides inside the sleeve and moves the pad, causing it to move downwards. This lifts the left side of the base plate, changing its tilt angle. The base plate then moves the small diesel engine. When the small diesel engine is in a horizontal position, the rotating wheel stops rotating, making it easier to keep the small diesel engine in a horizontal position when parked on a sloping surface.

[0024] The present invention will be further described below with reference to the accompanying drawings:
[0025] See attached document Figure 1-7 In this embodiment, a portable small diesel engine includes a base plate 1 and a first bracket 2. The first bracket 2 is fixedly connected to the bottom of the base plate 1. A moving mechanism 3 is provided inside the first bracket 2 to facilitate the movement of the small diesel engine 9. A second bracket 5 is fixedly connected to the bottom of the base plate 1. A support mechanism 4 is provided inside the second bracket 5. The vertical position of the pad 408 in the support mechanism 4 can be adjusted to keep the small diesel engine 9 in a horizontal position. A first vertical plate 6 is fixedly connected to the left side of the base plate 1. Two handrails 7 are fixedly connected to the left side of the first vertical plate 6 to facilitate pushing the small diesel engine 9. A groove 8 is provided inside the base plate 1.
[0026] The groove 8 is clearance-fitted with the outer wall of the small diesel engine 9, and the groove 8 provides initial positioning for the small diesel engine 9. Two second vertical plates 10 are fixed to the upper surface of the base plate 1, and a threaded block 11 is fixed above the second vertical plates 10. The second vertical plates 10 support and position the threaded block 11. The threaded block 11 is internally threaded with a screw 12. The horizontal position of the screw 12 changes when it rotates. The outer wall of the end of the screw 12 is rotatably connected to a clamping plate 13 through a bearing. The screw 12 drives the clamping plate 13 to move, and the clamping plate 13 fits against the outer wall of the small diesel engine 9. The clamping plates 13 on the left and right sides further position the small diesel engine 9. After the clamping plate 13 fits against the small diesel engine 9, it will not rotate when the screw 12 continues to rotate.
[0027] The moving mechanism 3 includes a first slide rod 301, a first slider 302, a spring 303, a first support rod 304, a support plate 305, a second support rod 306, and a wheel 307. The first slide rod 301 is fixedly connected to the inside of the first bracket 2. Two first sliders 302 are slidably connected to the outer wall of the first slide rod 301. The two first slide rods 302 slide on the outer wall of the first slide rod 301. A spring 303 is sleeved on the outer wall of the first slide rod 301. The type of spring 303 is selected according to actual usage requirements to meet the working needs. The two ends of the spring 303 are fixedly connected to the first bracket 2 and the first slider 302, respectively. Damping pads are provided at the connection points of the spring 303 with the first bracket 2 and the first slider 302 to prevent the spring 303 from continuously reciprocating under elastic action. The first support rod 304 is rotatably connected to the bottom of the first slider 302 via a pin. The first slider 302 is driven by... The first support rod 304 moves, and the ends of both first support rods 304 are rotatably connected to the support plate 305 through pins. The two first support rods 304 drive the support plate 305 to move. The front and rear surfaces of the support plate 305 are fixed with second support rods 306. The support plate 305 and the second support rods 306 move together. The interior of the first bracket 2 is provided with a sliding groove to facilitate the movement of the second support rod 306. The outer wall of the end of the second support rod 306 is rotatably connected to the wheel 307 through a bearing. The second support rod 306 provides support for the wheel 307. The outer wall of the support plate 305 is fixed with a second slider 14. The support plate 305 drives the second slider 14 to move. The second slider 14 is slidably connected to the outer wall of the second slide rod 15. The second slider 14 slides on the outer wall of the second slide rod 15. The second slide rod 15 is fixed inside the first bracket 2. The second slider 14 and the second slide rod 15 provide guidance for the movement of the support plate 305.
[0028] The wheel 307 rolls on the ground. When the wheel 307 passes over an uneven surface, its vertical position changes. The wheel 307 drives the second support rod 306 to move, the second support rod 306 drives the support plate 305 to move, the support plate 305 drives the two first support rods 304 to move, and the first support rods 304 drive the first slider 302 to move. The first slider 302 slides on the outer wall of the first slide rod 301 and compresses or stretches the spring 303. The spring 303 buffers the force, so that the wheel 307 does not bump when passing over an uneven surface. As a result, the small diesel engine 9 does not vibrate when moving on an uneven surface, thus avoiding damage to the internal structure of the small diesel engine 9.
[0029] Support mechanism 4 includes a worm 401, a rotating wheel 402, a worm gear 403, a first connecting rod 404, a pin 405, a second connecting rod 406, a sleeve 407, and a pad 408. The outer walls at both ends of the worm 401 are rotatably connected to the second bracket 5 via bearings. A rotating wheel 402 is fixedly connected to the end of the worm 401, driving the worm 401 to rotate. The worm 401 meshes with the worm gear 403, driving the worm gear 403 to rotate. The worm gear 403 is rotatably connected to the second bracket 5 via bearings. The first connecting rod 404 is fixedly connected to the surface of the worm gear 403, and the worm gear 403 carries... The first connecting rod 404 rotates, and the sliding groove provided in the first connecting rod 404 is slidably connected to the outer wall of the pin 405. The first connecting rod 404 drives the pin 405 to move through the sliding groove. The pin 405 is fixed to the surface of the second connecting rod 406. The pin 405 drives the second pin 406 to move. The outer wall of the second connecting rod 406 is slidably connected to the sleeve 407. The second connecting rod 406 slides inside the sleeve 407. The upper end of the sleeve 407 is fixedly connected to the base plate 1. The lower end of the second connecting rod 406 is fixedly connected to the pad 408. The second connecting rod 406 drives the pad 408 to move.
[0030] If the small diesel engine 9 is parked on a sloping surface, with the wheels 307 positioned on the higher side of the surface, the rotating wheels 402 on both sides are rotated. The rotating wheels 402 drive the worm gear 401 to rotate, which in turn drives the worm wheel 403 to rotate. The worm wheel 403 then drives the first connecting rod 404 to rotate. The first connecting rod 404 drives the pin 405 to move through an internal groove. The pin 405 then drives the second connecting rod 406 to move. The second connecting rod 406 slides inside the sleeve 407 and moves the pad 408. The pad 408 moves downward, lifting the left side of the base plate 1 and changing the tilt angle of the base plate 1. The base plate 1 then drives the small diesel engine 9 to move. When the small diesel engine 9 is in a horizontal position, the rotating wheels 402 stop rotating. This makes it easier to keep the small diesel engine 9 in a horizontal position when parked on a sloping surface.
[0031] Working principle:
[0032] When using this portable small diesel engine, the small diesel engine 9 is placed inside the groove 8, and the position of the small diesel engine 9 is initially fixed. The screws 12 on both sides are rotated, and the horizontal position of the screws 12 changes when they rotate. The screws 12 drive the clamping plate 13 to move, and the clamping plate 13 fits against the outer wall of the small diesel engine 9 to further fix the position of the small diesel engine 9.
[0033] Small diesel engine mobile phase:
[0034] The worker holds two handrails 7 with both hands and lifts them upwards. The handrails 7 move the first vertical plate 6, separating it from the ground. This pushes the two handrails 7 forward, causing the small diesel engine 9 to move forward as well. The wheels 307 contact the ground and roll. When the wheels 307 pass over uneven surfaces, their vertical position changes, causing the wheels 307 to move the second support rod 306. The second support rod 306 then moves the support plate 305, which in turn drives the two first support rods 304. The first support rods 304 then drive the first slider. 302 moves, the first slider 302 slides on the outer wall of the first slider 301 and squeezes or stretches the spring 303. The spring 303 buffers the force so that the wheel 307 will not bump when passing over uneven road surfaces. Thus, when the small diesel engine 9 moves on uneven road surfaces, the small diesel engine 9 itself will not vibrate, avoiding damage to the internal structure of the small diesel engine 9. When moving the small diesel engine 9, hold the handle bar 7 and push it. The wheel 307 rolls on the road surface, making the small diesel engine 9 easy to move.
[0035] Small diesel engine parking phase:
[0036] When the small diesel engine 9 is moved to the desired position, if the road surface is level, the two handrails 7 are released, and the first vertical plate 6 contacts the road surface, cooperating with multiple wheels 307 to support the base plate 1, so that the small diesel engine 9 is in a near-level position. If the road surface where the small diesel engine 9 is parked is sloping, the small diesel engine 9 is in a tilted position, so that the wheels 307 are on the higher side of the road surface. The rotating wheels 402 on both sides are rotated, and the rotating wheels 402 drive the worm gear 401 to rotate. The worm gear 401 drives the worm wheel 403 to rotate. 3 drives the first connecting rod 404 to rotate. The first connecting rod 404 drives the pin 405 to move through the internal sliding groove. The pin 405 drives the second connecting rod 406 to move. The second connecting rod 406 slides inside the sleeve 407 and drives the pad 408 to move. The pad 408 moves downward, and the left side of the base plate 1 is supported. The tilt angle of the base plate 1 changes. The base plate 1 drives the small diesel engine 9 to move. When the small diesel engine 9 is in a near-horizontal state, the rotating wheel 402 stops rotating. When parking on a sloping road surface, it is easy to keep the small diesel engine 9 in a horizontal state.
