Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a leveling sealing joint. Background Art

[0002] In liquid transmission systems, the connection between the oil pump and the filter is a critical link to ensure the normal operation of the system. Traditional connection methods usually use double-wire connectors to achieve the connection between the oil pump and the filter. As a common connection component, the double-wire connector is designed to provide a stable and reliable connection and prevent liquid leakage through specific sealing methods. However, although the double-wire connector and its supporting sealing medium have certain technical advantages, there is a problem in practical application. That is, after installation, the relative orientation between the filter and the oil pump is often uncertain. Because the double-wire connector itself does not have a direction-limiting function, the filter may be connected in a different direction relative to the oil pump each time it is installed.

[0003] This directional uncertainty creates significant challenges in the design and maintenance of liquid transfer systems. For example, in certain applications, filters must maintain a specific orientation to ensure effective filtration or meet other technical requirements. If the orientation of the filter and pump cannot be aligned, additional adjustments or calibrations are required during each installation, increasing installation complexity and costs while potentially impacting overall system performance and reliability.

[0004] Therefore, how to provide a connection structure and method that can ensure that the filter and the oil pump can maintain leveling and sealing each time they are installed has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The utility model aims to provide a leveling sealing joint to ensure that the connection structure between the filter and the oil pump can be kept leveling and sealing each time they are installed.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A leveling sealing joint, which is used to connect a filter and an oil pump. The leveling sealing joint includes a tube body, one end of the tube body is a first connector for connecting to the filter, and the other end of the tube body is a second connector for connecting to the oil pump. A fixing nut, an O-ring and a large nut are installed around the middle of the tube body. The fixing nut is fixedly installed with the first connector, the O-ring is installed on the side close to the second connector, and the large nut is movably installed between the fixing nut and the O-ring. The inner diameter of the large nut is smaller than the outer diameter of the O-ring, but the inner diameter of the large nut is larger than the inner diameter of the O-ring.

[0008] Preferably, the tube body is a thick-walled hollow tube.

[0009] Preferably, the large nut and the fixing nut are polygonal structures.

[0010] Preferably, the thickness of the large nut is thinner than that of the fixing nut, and the outer diameter of the large nut is larger than that of the fixing nut.

[0011] Preferably, the O-ring is made of elastic material.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The design of the movable large nut allows the filter and oil pump to be leveled during movement.

[0014] 2. The design of the combination of a movable large nut and an O-ring can seal the interface after leveling the filter and the oil pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. The embodiments described below are only some of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 and Figure 2 The utility model provides a leveling sealing joint, and the technical solution is as follows:

[0020] like Figure 1 and Figure 2As shown, a leveling sealing joint, the leveling sealing joint 1 is used to connect the filter 2 and the oil pump 3, the leveling sealing joint 1 includes a tube body 11, one end of the tube body 11 is a first connector 12 for connecting the filter 2, the other end of the tube body 11 is a second connector 13 for connecting the oil pump 3, a fixing nut 14, an O-ring 15 and a large nut 16 are installed around the middle of the tube body 11, the fixing nut 14 is fixedly installed with the first connector 12, the O-ring 15 is installed on the side close to the second connector 13, and the large nut 16 is movably installed between the fixing nut 14 and the O-ring 15, the inner diameter of the large nut 16 is smaller than the outer diameter of the O-ring 15, but the inner diameter of the large nut 16 is larger than the inner diameter of the O-ring 15.

[0021] The first connector 12 of the tube body 11 is fixedly connected to the filter 2, and the second connector 13 of the tube body 11 is movably connected to the oil pump 3. In terms of the direction from the first connector to the second connector, there are a fixing nut 14, a large nut 16 and an O-ring 15 in sequence. The fixing nut 14 is fixedly connected to the first connector 12 to seal the first connector 12. The inner diameter of the large nut 16 is smaller than the outer diameter of the O-ring 15 and larger than the inner diameter of the O-ring 15, so that the large nut 16 can squeeze the O-ring 15. When the end of the filter 2 is downward, the large nut 16 at the movable end is tightened, and then the O-ring is pressed to form a sealing surface, so as to ensure that the relative positions of the oil pump 3 and the filter 2 are consistent each time they are installed.

[0022] like Figure 1 and Figure 2 As shown, the tube body 11 is a thick-walled hollow tube.

[0023] The pipe body 11 is designed to be thick-walled and hollow because the pipe can withstand higher pressure due to its thicker wall, and thus has a higher bearing capacity, which enables it to withstand a larger load.

[0024] like Figure 1 and Figure 2 As shown, the large nut 16 and the fixing nut 14 are polygonal structures.

[0025] The large nut 16 and the fixing nut 14 can be designed as a polygonal structure or a circular structure, preferably a polygonal structure. Polygonal nuts (such as hexagonal nuts) are one of the most stable polygons in mechanics, can provide uniform stress distribution, and reduce deformation during tightening or loosening. Polygonal nuts can disperse force better than circular nuts. The six faces disperse the force acting on the nut, making the nut more stable and reducing the risk of damage caused by concentrated force. In addition, the design of the polygonal nut makes it easy for tools such as wrenches or screwdrivers to cooperate with it, providing rotational torque from multiple directions, making it easier to tighten or loosen the nut, which can improve work efficiency and facilitate disassembly.

[0026] like Figure 1 and Figure 2 As shown, the thickness of the large nut 16 is thinner than that of the fixing nut 14 , and the outer diameter of the large nut 16 is larger than that of the fixing nut 14 .

[0027] The thicker fixing nut 14 can provide a stable connection and seal when connected to the first joint. The design that the outer diameter of the large nut 16 is larger than the outer diameter of the fixing nut 14 can easily distinguish the large nut 16 that needs to be tightened, and the outer diameter of the large nut 16 is larger than the outer diameter of the fixing nut 14, which makes it easier to tighten or loosen the large nut 16 with a wrench.

[0028] like Figure 1 and Figure 2 As shown, the O-ring 15 is made of elastic material.

[0029] The O-ring 15 is designed to be made of elastic material so that it can better combine with the large nut 16, making it convenient to adjust the direction of the filter 2 and the oil pump 3. It has good elasticity and resilience, and can fit tightly with the large nut 16 and other sealing surfaces to form an effective seal.

[0030] Working principle: The first connector 12 of the leveling sealing joint 1 is first sealed and connected to the filter 2, and the second connector 13 is then connected to the oil inlet of the oil pump 3. When the end of the filter 2 is downward, the large nut 16 is tightened onto the second connector 13, and then the O-ring is compressed to form a sealing surface, thereby ensuring that the relative positions of the oil pump 3 and the filter 2 are consistent each time they are installed.

[0031] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
