Description

Technical Field

[0001] This utility model relates to the field of diesel engine technology, specifically to a vertical twin-cylinder compact diesel engine block. Background Technology

[0002] The upright twin-cylinder compact diesel engine block is a high-efficiency power core component of diesel engines that combines an upright cylinder layout, twin-cylinder configuration, and compact structural design. It is widely used in small equipment with comprehensive requirements for space, weight, and power. For example, in prior art 1 (Chinese patent application number CN202421445672.9, application date 2024-06-24), a V-type twin-cylinder high-precision diesel engine block is used. Through a fixing mechanism, the V-type twin-cylinder diesel engine block is quickly fixed. In the fixing mechanism, by rotating a two-way lead screw, the first clamping frame and the second clamping frame move in opposite directions, thereby fixing the diesel engine body with the base installed. This solves the problem of equipment damage caused by the inconvenience of installation and fixing in the prior art.

[0003] While existing technologies can enable quick and easy installation of diesel engine equipment to improve its efficiency, in actual use, most diesel engines are simply connected to external pipes directly through the inlet and outlet pipes for water supply and pumping. However, this direct connection method can cause the pipes to loosen and fall off due to vibrations during use, reducing the stability of the pipe connections and making them less practical. Therefore, the vertical twin-cylinder compact diesel engine block has been proposed to effectively solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical twin-cylinder compact diesel engine block to solve the problem mentioned in the background art. Currently, most diesel engines on the market are used by directly connecting external pipes to the water inlet and outlet pipes for water supply and pumping. However, this direct connection method can cause the pipes to loosen and fall off due to vibrations generated during use, reducing the connection stability of the pipes and resulting in poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical twin-cylinder compact diesel engine body, including a body and a base disposed below the body. A water inlet pipe and a water outlet pipe are respectively installed on the upper part of the body, and plugs are respectively connected through the interior of the water inlet pipe and the water outlet pipe. A water supply pipe is connected above the two plugs. An output end is also provided on the outer side of the body. Two limiting blocks are slidably installed inside the plugs, and the outer ends of the two limiting blocks extend through the interior of the water inlet pipe. Two top plates are correspondingly located below the plugs, and the two top plates are disposed inside the water inlet pipe.

[0006] Preferably, the outer surfaces of the two limiting blocks are inclined, and the two limiting blocks are symmetrically arranged about the vertical center line of the plug.

[0007] Preferably, the plug has two compression springs connected to one end inside, and the two compression springs have the same structure, and the other end of the two compression springs is connected to a limit block.

[0008] Preferably, two pressing rods are slidably installed through the inside of the water inlet pipe, and the inner ends of the two pressing rods are arc-shaped, and the inner ends of the two pressing rods correspond to limit blocks.

[0009] Preferably, one end of a reset spring is connected to the outer side of the two pressing rods, and the other end of the two reset springs is connected to the inner wall of the water inlet pipe.

[0010] Preferably, two support rods are rotatably mounted below the top plate, and the two support rods are inclined, and a movable block is rotatably connected below the two support rods.

[0011] Preferably, the two movable blocks are slidably mounted inside the water inlet pipe by means of a storage spring, wherein the two storage springs have the same structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) Setting limit blocks: When it is necessary to quickly position and fix the water supply pipe, simply insert the plug connected to the water supply pipe into the inside of the water inlet pipe and the drain pipe respectively. At this time, the two inclined limit blocks will shrink and move by the squeezing of the water inlet pipe or the drain pipe, so that the two limit blocks shrink and move into the inside of the water inlet pipe or the drain pipe. Then, the two compression springs will automatically spring the two limit blocks into the inside of the water inlet pipe or the drain pipe by their own elasticity, so as to fix the position of the plug after insertion, avoid the phenomenon of loosening and falling off the water supply pipe during use, and improve stability.

[0014] (2) Furthermore, when it is necessary to disassemble and replace the inserted water pipe, simply press the two pressing rods to squeeze the two limiting blocks to retract and move them, so that the two limiting blocks retract and move into the inside of the plug. At this time, the plug can be taken out from the inside of the water inlet pipe or the drain pipe, so as to realize the quick disassembly and replacement of the water pipe, which is more time-saving and labor-saving.

[0015] (3) A reset spring is provided. The water inlet pipe is connected to the outer side of the two pressing rods through the reset spring. The reset spring can be used to elastically reset the position of the pressing rod after pressing, so as to facilitate repeated pressing, disassembly and replacement in the later stage, and the practicality is better.

[0016] (4) A top plate is provided. Two top plates are provided inside the water inlet pipe or the drain pipe. Then, there are plugs above the two top plates. When the plug is inserted into the water inlet pipe or the drain pipe, the plug will simultaneously squeeze the two support rods and drive the two moving blocks to store force through the two energy storage springs to facilitate the subsequent auxiliary disassembly and replacement.

[0017] (5) Furthermore, during the process of disassembling and replacing the plug with the water inlet pipe or the drain pipe, the two energy-squeezing springs will use their own elasticity to reset the two moving blocks after the two energy-squeezing. At this time, the two moving blocks will simultaneously drive the two support rods to drive the two top plates to push the plug out from the inside of the water inlet pipe or the drain pipe, so as to assist the water supply pipe to be replaced quickly.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution: a vertical twin-cylinder compact diesel engine block.

[0027] Example 1: To address the problem that in most existing diesel engines, external pipes are directly connected to the inlet pipe 3 and drain pipe 4 for water supply and pumping, but this direct connection can cause the pipes to loosen and detach due to vibrations during use, reducing connection stability and practicality, the following solution is disclosed: An engine body 1 and a base 2 located below the engine body 1. An inlet pipe 3 and a drain pipe 4 are respectively installed on the top of the engine body 1, and plugs 5 are respectively connected through the interior of the inlet pipe 3 and the drain pipe 4. Figure 1 and Figure 2 As shown, water supply pipes 6 are connected above the two plugs 5, and an output end 15 is also provided on the outer side of the body 1. Two limiting blocks 7 are slidably installed inside the plugs 5, and the outer ends of the two limiting blocks 7 extend through into the interior of the water inlet pipe 3. There are two top plates 10 corresponding to the bottom of the plugs 5, as shown. Figure 3 As shown, the two top plates 10 are located inside the water inlet pipe 3.

[0028] The outer surfaces of the two limiting blocks 7 are inclined, and the two limiting blocks 7 are symmetrically arranged about the vertical center line of the plug 5. The plug 5 is internally connected to one end of two compression springs 14, and the two compression springs 14 have identical structures, such as... Figure 4 As shown, the other ends of the two compression springs 14 are connected to the limit block 7. Two pressing rods 8 are slidably installed inside the water inlet pipe 3, and the inner ends of the two pressing rods 8 are arc-shaped. The inner ends of the two pressing rods 8 correspond to the limit block 7. One end of the return spring 9 is connected to the outer side of the two pressing rods 8, and the other end of the two return springs 9 is connected to the inner wall of the water inlet pipe 3.

[0029] When it is necessary to connect the diesel engine's inlet pipe 3 or drain pipe 4 to the external water supply pipe 6, simply insert the connector 5 of the water supply pipe 6 into the inlet pipe 3 and drain pipe 4 respectively. Figure 1 and Figure 2 As shown, the two inclined limiting blocks 7 will retract and move under the pressure of the inlet pipe 3 or the drain pipe 4, causing the two limiting blocks 7 to retract and move into the interior of the inlet pipe 3 or the drain pipe 4. At this time, the two compression springs 14 will automatically spring the two limiting blocks 7 into the interior of the inlet pipe 3 or the drain pipe 4 through their own elastic force, thereby achieving the positioning and fixing of the inserted plug 5. Figure 3 As shown, this design avoids the water supply pipe 6 from loosening and falling off during later use, resulting in better stability.

[0030] When it is necessary to disassemble and replace the inserted water pipe 6, simply press the two pressing rods 8, which will cause the two return springs 9 to compress and retract the two limiting blocks 7, so that the two limiting blocks 7 retract and move into the interior of the plug 5. Figure 4 As shown, at this point, the plug 5 can be removed from the inside of the water inlet pipe 3 or the drain pipe 4 to allow for quick disassembly and replacement of the water supply pipe 6.

[0031] Example 2 differs from Example 1 in that the water supply pipe 6 can be quickly and assisted in disassembling and replacing via the top plate 10, thereby improving the efficiency of disassembling and replacing the water supply pipe 6 and making the operation more time-saving and labor-saving. The following is disclosed:

[0032] Two support rods 11 are rotatably mounted below the top plate 10, such as... Figure 5 As shown, the two support rods 11 are inclined, and movable blocks 12 are rotatably connected to the lower part of the two support rods 11. The two movable blocks 12 are slidably installed inside the water inlet pipe 3 by means of storage springs 13. The two storage springs 13 have the same structure, as shown in the figure. Figure 6 As shown.

[0033] During the insertion of plug 5 into the inlet pipe 3 or drain pipe 4, plug 5 simultaneously compresses the two support rods 11, driving the two moving blocks 12 to accumulate pressure through the two storage springs 13. Figure 5 As shown, during the process of disassembling and replacing the plug 5 with the inlet pipe 3 or the drain pipe 4, the two pressure-accumulating springs 13 will use their own elasticity to reset the two moving blocks 12 after being pressure-accumulated. At this time, the two reset moving blocks 12 will simultaneously drive the two support rods 11 to drive the two top plates 10 to push the plug 5 out of the inside of the inlet pipe 3 or the drain pipe 4. Figure 6 As shown, the auxiliary water supply pipe 6 allows for quick replacement, making the operation more time-saving and labor-saving.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
