[0046] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

Therefore, a specific feature, structure or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, terms such as "example", "exemplary", etc. are used "for purposes of example, instance or illustration.

Instead, the use of terms such as "example", "exemplary", etc. is intended to present concepts in a specific manner.

[0048] During the use of a diesel engine, due to different use environments, the temperature of the internal engine oil may be too high or too low. Therefore, pipelines need to be arranged in the engine oil of the diesel engine to connect other refrigerants or heat carriers through the pipelines, so that the engine oil can be quickly cooled or quickly heated. However, the inventor found that when a refrigerant or heat carrier is introduced into the pipeline, it will cause the pipeline to vibrate. The above vibration is likely to cause oil leakage and leakage of the refrigerant or heat carrier. And because a refrigerant or heat carrier needs to be introduced, it is necessary to frequently install and disassemble external pipelines on the pipeline to input the refrigerant or heat carrier. Frequently installing and disassembling the external pipeline will cause the pipeline to be subjected to an axial force, resulting in the pipeline becoming loose, and then affecting the seal between the pipeline and the diesel engine, resulting in oil leakage.

[0049] The defects existing in the above solutions are all the results obtained by the inventors through practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed in this disclosure by the present disclosure for the above problems should all be the contributions made by the inventors to the present disclosure during the process of the present disclosure.

[0050] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0051] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0052] As Figure 1 shown, at least one disclosed embodiment provides a joint for a diesel engine, including: a clamping mechanism 12, the clamping mechanism 12 is arranged on the connecting pipe 11; a protection mechanism 13, the protection mechanism 13 is movably arranged on the connecting pipe 11, and the protection mechanism 13 is adapted to wrap the end of the connecting pipe 11 for connecting an external pipe; when the protection mechanism 13 moves towards the clamping mechanism 12, it drives the clamping mechanism 12 to clamp the connecting pipe 11, thereby realizing that when the connecting pipe 11 is connected to an external refrigerant or heat medium, the connecting pipe 11 is clamped by the clamping mechanism 12, avoiding the shaking of the connecting pipe 11, avoiding the leakage of engine oil in the diesel engine caused by the shaking, and avoiding the leakage of refrigerant or heat medium in the connecting pipe 11 caused by the shaking.

[0053] As Figure 1 shown, in an alternative embodiment, the clamping mechanism 12 includes: a fixing ring 121; the fixing ring 121 is sleeved on the connecting pipe 11; a connecting strip 122 is equidistantly arranged along the circumferential direction of the fixing ring 121 on one side wall of the fixing ring 121; the connecting strip 122 is inclined, and the distance between the end of the connecting strip 122 far from the fixing ring 121 and the outer wall of the connecting pipe 11 is longer than that of the other end; a convex block 123 is arranged on the surface of the connecting strip 122 far from the connecting pipe 11.

[0054] In this embodiment, the fixing ring 121 is fixedly connected to the connecting pipe 11, and thus the connecting pipe 11 can be firmly installed on the housing 2 through the interference fit between the connecting strip 122 and the inner wall of the inlet 22 or outlet 23 on the diesel engine housing 2.

[0055] In this embodiment, the connecting strip 122 can be made of an elastic material. When the protection mechanism 13 approaches and presses the connecting strip 122, the connecting strip 122 can approach and contact the connecting pipe 11 to clamp the connecting pipe 11.

[0056] In this embodiment, there are multiple connecting strips 122, which are arranged around the connecting pipe 11. When the connecting strips 122 contact the connecting pipe 11, they can cooperate to hold the connecting pipe 11 tightly from multiple directions.

[0057] In this embodiment, a slope can be provided at one end of the connecting strip 122 close to the threaded sleeve 131, which is convenient for the slope of the threaded sleeve 131 to contact and cooperate with the slope of the connecting strip 122, so that the connecting strip 122 is pressed by the threaded sleeve 131 to approach the connecting pipe 11 and contact the connecting pipe 11, so as to hold the connecting pipe 11 tightly.

[0058] In this embodiment, after the connecting pipe 11 is installed in the corresponding inlet 22 or outlet 23 of the diesel engine housing 2, when the connecting strip 122 is not squeezed by the threaded sleeve 131, the convex block 123 on the connecting strip 122 is located in the corresponding card slot 24. At this time, the cooperation between the convex block 123 and the card slot 24 can reduce or offset the axial force exerted on the connecting pipe 11 when the external pipe is disassembled from or connected to the connecting pipe 11, avoiding the looseness between the connecting pipe 11 and the housing 2 caused by frequent installation and disassembly of the external pipe, and avoiding the influence on the sealing effect between the connecting pipe 11 and the housing 2 caused by the looseness of the connecting pipe 11.

[0059] As Figure 1 shown, in an optional embodiment, the protection mechanism 13 includes: a threaded sleeve 131; the threaded sleeve 131 is sleeved on the connecting pipe 11, and the threaded sleeve 131 is threadedly connected to the connecting pipe 11; the connecting strip 122 is located between the threaded sleeve 131 and the fixing ring 121; one side of the threaded sleeve 131 close to the fixing ring 121 is a slope; a limiting ring 132 is arranged around the outer wall of the threaded sleeve 131.

[0060] In this embodiment, the threaded sleeve 131 is in threaded cooperation with the connecting pipe 11, so that when the threaded sleeve 131 is rotated, the threaded sleeve 131 can move along the connecting pipe 11.

[0061] In this embodiment, after the joint 1 is installed at the corresponding outlet 23 or inlet 22, when the joint 1 has not been connected to the external pipe at this time, the convex block 123 is located in the corresponding card slot 24, and the threaded sleeve 131 completely wraps the end of the connecting pipe 11 extending out of the housing 2 to protect the thread on the end, avoiding damage to the thread caused by collision with other objects, etc., and avoiding the inability to firmly connect to the external pipe after the thread is damaged.

[0062] In this embodiment, the thread on the connecting pipe 11 can also be used to connect the external pipe.

[0063] In this embodiment, when the joint 1 is installed on the housing 2, the limiting ring 132 is located outside the housing 2, and a part of the threaded sleeve 131 can extend into the corresponding inlet 22 or outlet 23.

[0064] In this embodiment, when the connecting pipe 11 needs to be connected to an external pipe, the threaded sleeve 131 is rotated to expose the thread on the connecting pipe 11, and the length of the threaded sleeve 131 extending into the corresponding inlet 22 or outlet 23 increases. At this time, the outer wall of the threaded sleeve 131 contacts the inner wall of the corresponding inlet 22 or outlet 23, and the threaded sleeve 131 can be pressed by the inner wall of the inlet 22 or outlet 23 to closely adhere to the connecting pipe 11 to hold the connecting pipe 11 tightly. The threaded sleeve 131 gradually contacts and presses the connecting strip 122, causing the end of the connecting strip 122 away from the fixing ring 121 to gradually approach the connecting pipe 11 and driving the convex block 123 to gradually move out of the card slot 24. When the convex block 123 is about to completely move out of the card slot 24, the movement of the threaded sleeve 131 is stopped. At this time, the external pipe can be connected to the thread exposed on the connecting pipe 11. At this time, since the convex block 123 has not completely moved out of the card slot 24, the axial force applied to the connecting pipe 11 during the installation of the external pipe will be reduced or offset, preventing the connecting pipe 11 from loosening. When the external pipe is connected to the connecting pipe 11 and the end of the external pipe contacts the limiting ring 132, the threaded sleeve 131 is further rotated so that the limiting ring 132 contacts the outer wall of the housing 2. At this time, the threaded sleeve 131 moves to the limit position, and at the same time, the convex block 123 completely moves out of the card slot 24, and the connecting strip 122 contacts and holds the outer wall of the connecting pipe 11 tightly to hold the connecting pipe 11 tightly. Then, the external pipe is continuously installed until it contacts the limiting ring 132. At this time, the threaded sleeve 131 is clamped by the external pipe and the outer wall of the housing 2, causing the threaded sleeve 131 to be locked to prevent the threaded sleeve 131 from loosening and ensuring the holding effect of the connecting strip 122.

[0065] In this embodiment, when it is necessary to remove the external pipeline from the connecting pipeline 11, first loosen the external pipeline so that the external pipeline is separated from the limiting ring 132. After there is a certain distance between the limiting ring 132 and the external pipeline, stop the disassembly of the external pipeline. At this time, rotate the threaded sleeve 131 so that the threaded sleeve 131 moves away from the fixed ring 121. The pressed end of the connecting strip 122 returns in the direction away from the connecting pipeline 11, and the convex block 123 gradually re-inserts into the card slot 24 again. At this time, stop the rotation of the threaded sleeve 131 and completely remove the external pipeline. At this time, since part of the convex block 123 re-enters the card slot 24, the axial force exerted on the connecting pipeline 11 when disassembling the external pipeline will be reduced or offset, avoiding loosening of the connecting pipeline 11. When the external pipeline is removed, rotate the threaded sleeve 131 again so that the threaded sleeve 131 completely wraps the end of the connecting pipeline 11 to protect the end of the connecting pipeline 11; when removing the external pipeline, when the external pipeline is first loosened from the connecting pipeline 11 and there is a small distance between its end and the limiting ring 132, stop the removal of the external pipeline. This distance satisfies that after the threaded sleeve 131 moves, part of the convex block 123 can re-enter the corresponding card slot 24, and then continue to remove the external pipeline to minimize the influence of the axial force on the connecting pipeline 11 during the removal process.

[0066] In an alternative embodiment, threads are provided on the outer wall of the connecting pipeline 11, and the threads extend to the end of the connecting pipeline 11. The threaded sleeve 131 is adapted to the threads, and by rotating the threaded sleeve 131, the threaded sleeve 131 moves along the connecting pipeline 11 to approach or move away from the connecting strip 122.

[0067] As Figure 2 shown, at least one other disclosed embodiment also provides a diesel engine, including: a housing 2, a fuel storage chamber 21 is provided in the housing 2, and an inlet 22 and an outlet 23 communicating with the fuel storage chamber 21 are provided on the housing 2; the above-mentioned connectors 1 are provided at both the inlet 22 and the outlet 23, and the two connectors 1 are connected through a pipeline mechanism 3.

[0068] As Figure 2 shown, in an alternative embodiment, the pipeline mechanism 3 includes: at least two layers of pipelines 31; the pipelines 31 are in a continuous regular curved shape; one end of the pipeline 31 is communicated with the connecting pipeline 11 in the connector 1 at the inlet 22, and the other end is communicated with the connecting pipeline 11 in the connector 1 at the outlet 23.

[0069] In this embodiment, the pipelines 31 in a continuous regular curved shape can increase the contact area with the engine oil and improve the cooling or heating effect.

[0070] In this embodiment, the pipeline 31 can be three-layer or the like. The multi-layer pipeline 31 can increase the contact area between the pipeline 31 and the engine oil, improving the cooling or heating effect.

[0071] In an alternative embodiment, the connecting pipe 11 in the joint 1 passes through the corresponding outlet 23 or inlet 22 and enters the interior of the housing 2; the fixing ring 121 on the connecting pipe 11 is in interference fit with the inner wall of the corresponding outlet 23 or inlet 22.

[0072] As Figure 4 shown, in an alternative embodiment, clamping grooves 24 corresponding to the bumps 123 in the joint 1 are formed on the inner walls of the inlet 22 and the outlet 23.

[0073] As Figure 3 shown, in an alternative embodiment, a sealing nut 14 is provided on the connecting pipe 11. The sealing nut 14 is located in the oil storage cavity 21, and a sealing gasket is provided between the sealing nut 14 and the inner wall of the housing 2.

[0074] In this embodiment, the sealing gasket seals between the connecting pipe 11 and the oil storage cavity 21, preventing the leakage of the engine oil.

[0075] At least one other disclosed embodiment also provides an assembly method of using the above-mentioned diesel engine joint 1, including: when the protection mechanism 13 moves towards the clamping mechanism 12, it drives the clamping mechanism 12 to clamp the connecting pipe 11.

[0076] In summary, the diesel engine joint 1 of the present invention includes: a clamping mechanism 12 provided on the connecting pipe 11; a protection mechanism 13 movably provided on the connecting pipe 11, and the protection mechanism 13 is adapted to wrap the end of the connecting pipe 11 for connecting an external pipe; when the protection mechanism 13 moves towards the clamping mechanism 12, it drives the clamping mechanism 12 to clamp the connecting pipe 11, thereby realizing that when the connecting pipe 11 connects an external refrigerant or heat medium, the connecting pipe 11 is clamped by the clamping mechanism 12, avoiding the shaking of the connecting pipe 11, avoiding the leakage of the engine oil in the diesel engine caused by the shaking, and avoiding the leakage of the refrigerant or heat medium in the connecting pipe 11 caused by the shaking.

[0077] In the description of the embodiments of the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0078] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, terms such as "first", "second" and other numerical terms used herein do not imply order or sequence unless explicitly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer or section discussed above may be referred to as the second element, component, region, layer or section.

[0079] Spatially relative terms, such as "inner", "outer", "beneath", "below", "lower", "above", "upper", etc., may be used herein to facilitate describing the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientation depicted in the figures, spatially relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is turned over, an element described as "beneath" or "below" other elements or features will be oriented "above" the other elements or features. Thus, the exemplary term "beneath" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein are to be interpreted accordingly.

[0080] Based on the above inspiration from the ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
