Description

Technical Field

[0001] This utility model relates to the field of oil control valve technology, and in particular to an oil control valve core assembly that can be quickly disassembled and installed. Background Technology

[0002] In engine lubrication systems, the oil control valve core assembly plays a crucial role, its performance directly affecting the regulation of oil flow and pressure, and having a decisive impact on the normal operation and service life of the engine. With the continuous development of engine technology, higher requirements are being placed on the reliability, stability, and ease of maintenance of the oil control valve core assembly.

[0003] Currently, most oil control valve assemblies on the market employ a traditional fixed connection design. This method often requires multiple complex tools and cumbersome procedures for installation and disassembly. For example, when repairing or replacing the valve assembly, technicians need to spend a significant amount of time and effort on disassembly, reducing efficiency and increasing costs. Furthermore, frequent and complex disassembly and assembly operations can easily damage the valve assembly and related components, further affecting the performance and lifespan of the oil control valve.

[0004] While some improved solutions have emerged in existing technologies aimed at achieving rapid assembly and disassembly, these solutions still have many shortcomings. Some solutions, while achieving a certain degree of rapid assembly and disassembly, suffer from structural instability, leading to problems such as loosening and displacement of the valve core assembly during operation, affecting the accuracy of oil control. Other solutions, due to their overly complex structures, increase manufacturing costs, hindering large-scale application. Therefore, there is an urgent need for an oil control valve core assembly that can achieve rapid assembly and disassembly while ensuring structural stability and controllable costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-disassembly and assembly oil control valve core assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-release oil control valve core assembly includes a valve sleeve, a valve stem sleeve fixedly mounted inside the valve sleeve, and a detachable valve core assembly inside the valve stem sleeve. The valve core assembly includes a valve core coaxially mounted inside the valve sleeve, a valve stem coaxially mounted at the end of the valve core, and a triangular rod portion at the end of the valve stem. The triangular rod portion has three equal-length inclined planes equidistantly spaced along the circumference of the valve stem. The triangular rod portion is coaxially and slidably inserted into the valve stem sleeve. Two of the inclined planes of the triangular rod portion have telescopic grooves at their centers, and each telescopic groove is slidably fitted with... The valve stem sleeve has three equidistant circular positioning slots. Two telescopic rods are fixedly inserted into any two of the three positioning slots. A right-angle tie rod is hinged to the bottom of each telescopic rod. A rectangular groove is opened in the center of the valve stem of the right-angle tie rod. The right-angle bottom end of the right-angle tie rod slides into the rectangular groove. Two sliding seats are symmetrically arranged in the rectangular groove. A straight groove is opened in the center of each sliding seat. The right-angle bottom end of the right-angle tie rod is slidably embedded in the adjacent straight groove. An adjustment component for controlling the extension and retraction of the telescopic rod is provided on the opposite side of the sliding seat.

[0008] Through the above technical solutions, the oil control valve core assembly that can be quickly disassembled is equipped with a detachable valve core assembly. Through the cooperation of structures such as the triangular rod, telescopic groove, telescopic rod, and positioning groove, the telescopic rod can be squeezed back by the inclined groove during valve core installation. After it is in place, it automatically locks into the positioning groove for fixation. During disassembly, the adjustment component can make the telescopic rod disengage from the positioning groove, realizing quick installation and disassembly of the valve core, which greatly improves maintenance efficiency and reduces repair time and cost.

[0009] Preferably, the adjustment assembly includes L-shaped pull rods symmetrically arranged between opposite surfaces of the slide block, with a common rotating rod between the L-shaped pull rods, and two levers symmetrically arranged on the outer periphery of the rotating rod, the ends of which slide against the adjacent L-shaped pull rods.

[0010] The above technical solution enables precise control of the extension and retraction of the telescopic rod by rotating the lever to drive the L-shaped pull rod, thereby controlling the sliding of the slide block. This makes the disassembly of the valve core simpler and less strenuous, eliminating the need for complicated operating steps and professional tools, thus improving ease of use.

[0011] Preferably, the rotating rod rotates through the center of the valve stem.

[0012] Through the above technical solution: the rotating rod rotates through the center of the valve stem, ensuring the stability and reliability of the rotating rod during rotation. It can stably transmit the rotational force to the lever, enabling the adjustment component to operate stably. It also ensures that the telescopic rod can retract smoothly during disassembly, avoiding operational failure or component damage due to the shaking of the rotating rod.

[0013] Furthermore, an internal hexagonal nut is coaxially provided at the end of the rotating rod furthest from the rotating rod.

[0014] The above technical solution allows for easy operation with common hexagonal wrenches, reducing reliance on specialized tools and enabling maintenance personnel to quickly and conveniently tighten the valve stem. This further improves the efficiency of valve core disassembly and facilitates operation in various maintenance environments.

[0015] Furthermore, the inlet end of the valve stem sleeve has three beveled openings arranged in an equidistant circular array.

[0016] Through the above technical solutions, the bevel design at the inlet end of the valve stem sleeve guides and compresses the telescopic rod during valve core installation, allowing the telescopic rod to retract smoothly into the telescopic groove. This ensures that the triangular rod can be smoothly inserted into the valve stem sleeve, reducing installation resistance and making the installation process easier and faster, thus improving the accuracy and success rate of installation.

[0017] Preferably, a top spring is fitted on the valve stem near the position between the valve core and the valve stem sleeve.

[0018] Through the above technical solution: the top spring is sleeved near the valve stem between the valve core and the valve stem sleeve. After the valve core is installed in place, the top spring provides a certain preload, which enhances the stability of the valve core assembly during operation, prevents the valve core from displacing due to factors such as oil pressure fluctuations, and ensures the normal operation of the oil control valve and the accuracy of oil flow and pressure regulation.

[0019] Preferably, a return spring is provided between the bottom end of the telescopic rod and the bottom wall of the telescopic groove.

[0020] Through the above technical solutions: the return spring between the bottom end of the telescopic rod and the bottom wall of the telescopic groove can automatically return the telescopic rod to the positioning groove after it is compressed and retracted, realizing the automatic locking of the valve core and ensuring the stability of the valve core after installation; at the same time, the hinge design of the right-angle tie rod and the telescopic rod, together with the slide and the straight groove, allows the telescopic rod to move flexibly during disassembly, ensuring the smooth disassembly operation and improving the reliability and practicality of the entire component structure.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model, through its unique triangular rod section, telescopic positioning structure, and convenient adjustment component design, enables rapid disassembly and assembly of the valve core assembly, significantly improving maintenance efficiency and reducing maintenance costs. Simultaneously, the cooperation between the top spring and the return spring, combined with a stable positioning method, ensures the stability of the valve core assembly during operation, guaranteeing accurate oil control. Furthermore, the overall structure is simple and reasonable, effectively controlling manufacturing costs while ensuring functionality, thus possessing good practicality and promotional value.

[0023] The above description is merely an overview of the technical solution of this utility model.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Example 1, referring to Figures 1 to 6

[0033] This utility model provides a quick-release oil control valve core assembly, the specific structure of which is as follows:

[0034] Overall Architecture

[0035] The assembly mainly consists of a valve sleeve 1, a valve core assembly, and a valve stem sleeve 4. The valve stem sleeve 4 is fixedly installed inside the valve sleeve 1. Three equidistant bevels 41 are arranged in a circular array at the inlet end of the valve stem sleeve 4, which guide the subsequent movement of the telescopic rod 7. A detachable valve core assembly is located inside the valve stem sleeve 4. The valve core assembly includes a valve core 2 coaxially disposed inside the valve sleeve 1, and a valve stem 3 is coaxially connected to the end of the valve core 2.

[0036] Valve core assembly details

[0037] Valve stem and triangular rod portion: A triangular rod portion 31 is provided at the end of the valve stem 3. The triangular rod portion 31 has three inclined planes with equal side lengths, and is equidistantly provided along the circumference of the valve stem 3. The triangular rod portion 31 is coaxially slidably inserted into the valve stem sleeve 4. Its structural design provides specific guidance for the installation of the valve core assembly within the valve stem sleeve 4.

[0038] Telescopic and Positioning Structure: Telescopic grooves 6 are formed at the center of two inclined surfaces of the triangular rod portion 31, and telescopic rods 7 are slidably embedded inside the telescopic grooves 6. A return spring 8 is provided between the bottom end of the telescopic rod 7 and the bottom wall of the telescopic groove 6 to provide power for the return of the telescopic rod 7. Three positioning grooves 42 are formed in an equidistant circular array on the valve stem sleeve 4. Two telescopic rods 7 can be fixedly inserted into any two of the three positioning grooves 42 to achieve positioning of the valve core assembly within the valve stem sleeve 4.

[0039] Transmission connection structure: A right-angle pull rod 9 is hinged to the bottom end of the telescopic rod 7. A rectangular groove 10 is opened in the center of the valve stem 3. The right-angle bottom end of the right-angle pull rod 9 slides into the interior of the rectangular groove 10. Two sliding seats 11 are symmetrically arranged in the rectangular groove 10. Each sliding seat 11 has a straight groove 1101 in its center. The right-angle bottom end of the right-angle pull rod 9 is slidably embedded in the adjacent straight groove 1101. Adjustment components are provided on the opposite surfaces of the sliding seats 11.

[0040] Adjustment assembly: The adjustment assembly includes L-shaped pull rods 12 symmetrically arranged between opposite faces of the slide block 11. A common rotating rod 13 is provided between the L-shaped pull rods 12. The rotating rod 13 rotates through the center of the valve stem 3, and two levers 14 are symmetrically arranged on its outer circumference. The ends of the levers 14 slide against the adjacent L-shaped pull rods 12. An internal hexagonal nut 15 is coaxially provided at the end of the rotating rod 13 furthest from itself, facilitating operation of the rotating rod 13 using a hexagonal wrench.

[0041] Elastic component: A top spring 5 is fitted on the valve stem 3 near the position between the valve core 2 and the valve stem sleeve 4. The top spring 5 plays a certain role in buffering and resetting, ensuring the stability of the valve core assembly during operation.

[0042] Working principle:

[0043] Installation process

[0044] When installing the valve core assembly, first align the triangular rod 31 with the inlet of the valve stem sleeve 4. Since the three equidistant inclined surfaces of the triangular rod 31 match the internal structure of the valve stem sleeve 4, accurate positioning and insertion are possible. During insertion, the triangular rod 31 slides along the inside of the valve stem sleeve 4. When the two telescopic rods 7 abut against the corresponding inclined slots 41, as the valve stem 3 continues to be pushed, the inclined slots 41 exert a squeezing force on the telescopic rods 7, causing the telescopic rods 7 to overcome the elastic force of the return spring 8 and slide into the telescopic groove 6 until they are fully inserted. At this point, the triangular rod 31 can continue to slide smoothly within the valve stem sleeve 4. When the telescopic rod 7 moves to the position of the positioning groove 42, since it is no longer subjected to the squeezing force of the inclined slot 41, the return spring 8 releases its elastic force, pushing the telescopic rod 7 to automatically return to its original position, allowing it to insert into the positioning groove 42. In this way, the valve core assembly is fixed through the cooperation of the telescopic rods 7 and the positioning groove 42. During normal operation, it cannot be displaced by external forces, ensuring the normal operation of the oil control valve.

[0045] Disassembly process

[0046] When the valve core assembly needs to be disassembled, use a hex wrench to turn the internal hex nut 15, which drives the rotating rod 13 to rotate. As the rotating rod 13 rotates, the lever 14 on its outer circumference also rotates. During the rotation of the lever 14, pressure is applied to the L-shaped pull rod 12, causing the L-shaped pull rod 12 to push the slide block 11 to slide horizontally in the same direction along the rectangular groove 10. At this time, the distance between the two slide blocks 11 decreases. Since the right-angle bottom end of the right-angle pull rod 9 is slidably embedded in the straight groove 1101 of the slide block 11, the sliding of the slide block 11, through the cooperation between the straight groove 1101 and the right-angle bottom end of the right-angle pull rod 9, drives the right-angle pull rod 9 to move. When the right-angle pull rod 9 moves, because it is hinged to the telescopic rod 7, it will produce displacement and a certain angle of rotation, thereby pulling the telescopic rod 7 to slide along the telescopic groove 6, causing the telescopic rod 7 to gradually separate from the positioning groove 42. Once the telescopic rod 7 is completely separated from the positioning groove 42, the entire valve core can be quickly removed. During this process, the presence of the top spring 5 provides some assistance in disassembling the valve core assembly, making the disassembly operation smoother.

[0047] In summary, this utility model, through its ingenious structural design, enables the rapid installation and disassembly of the valve core assembly, improves the maintenance efficiency of the oil control valve, and has good practicality and promotional value.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
