Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of oil control devices, specifically relating to a grease oil control device. Background Technology
[0002] In industrial production, bearings, gears, and other moving parts of various mechanical equipment require continuous lubrication with grease to reduce friction and wear, ensuring stable operation. Currently, grease supply relies heavily on traditional oil control devices, which have several shortcomings, including but not limited to: First, the devices have complex designs, often requiring multiple fixed connections to the equipment body, involving cumbersome mechanical adaptations and adjustments, resulting in time-consuming and labor-intensive installation, making simplified assembly difficult. Second, maintenance and disassembly are inconvenient. Because key components (such as valve bodies and metering mechanisms) are integrated or semi-fixed with the device body, multiple related components must be disassembled for replacement when a component malfunctions, significantly reducing maintenance efficiency. Third, for scenarios with multiple dispersed lubrication points, existing devices lack effective integrated management solutions. Each lubrication point requires a separate oil control device, increasing equipment investment costs and leading to chaotic pipeline layouts, hindering centralized monitoring and unified maintenance, and failing to meet the requirements of modern industrial production for efficient and convenient equipment maintenance. Utility Model Content

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example
[0024] like Figures 1-5 As shown, the present invention provides a grease control device, including an oil circuit valve block 1 and an electromagnet 2. The oil circuit valve block 1 is provided with an oil passage 3, and the input end of the oil passage 3 is provided with an oil inlet 4. The upper side of the oil circuit valve block 1 is divided into multiple positioning grooves 5. Each positioning groove 5 is provided with a fixing screw hole 6 at the four corners. Each positioning groove 5 is provided with an oil inlet 7 and an oil outlet 8. The oil circuit valve block 1 is provided with an oil outlet 9 on the side of each positioning groove 5. The input end of the oil outlet 9 is connected to the oil outlet 8.
[0025] The positioning groove 5 is fitted with an oil control valve block 10 through a fixing screw hole 6. The oil control valve block 10 has an oil chamber 11, which is connected to the oil inlet 7 and the oil outlet 8. The output end of the electromagnet 2 is connected to a piston rod 12 located in the oil chamber 11. The piston rod 12 is coaxial with the oil chamber 11. The piston rod 12 is fixedly fitted with a first block 13 and a second block 14. The size of the first block 13 corresponds to the size of the oil inlet 7, and the size of the second block 14 corresponds to the size of the oil outlet 8. The gap between the first block 13 and the second block 14 is matched with that of the oil chamber 11. When the second block 14 is located directly above the input end of the oil outlet 8, the output end of the oil inlet 7 is located between the first block 13 and the second block 14.
[0026] In this implementation case, it is first explained that the specifications and models of electromagnet 2 include, but are not limited to, the through-pull type miniature DC electromagnet KK-0530B. This model of electromagnet 2 can be purchased directly, and its installation and use are simple. It is not difficult for technical personnel in related fields to understand its operating principle and debugging of the operating mode. Secondly, it is explained that the input end of the oil inlet 4 is connected to the oil supply equipment and maintains a constant oil supply pressure.
[0027] Lubricating grease (hereinafter referred to as "oil") enters the oil chamber 11 through the oil inlet 7 connected by the oil passage 3 under the oil pressure of the oil supply equipment. Because it is blocked by the position between the first block 13 and the second block 14 in the static state, the oil will fill the space between the first block 13 and the second block 14 in the oil chamber 11. In this state, the oil outlet 9 at this position will not discharge oil. When oil needs to be discharged, the electromagnet 2 operates, pushing the piston rod 12 forward. Correspondingly, the first block 13 and the second block 14... The position of the oil in the oil chamber 11 changes, causing the input end of the oil outlet 8 to be opened. It should be noted that when the input end of the oil outlet 8 is opened, the output end of the oil inlet 7 will not be blocked by the first block 13, so as to achieve the purpose of continuous oil supply. After passing through the oil outlet 8, the oil is discharged from the oil outlet 9, thus achieving the purpose of oil supply. When the oil supply is completed, the electromagnet 2 retracts the piston rod 12, causing the second block 14 to block the input end of the oil outlet 8, thus stopping the oil supply. That is, the purpose of oil control is achieved by controlling the operation of the electromagnet 2.
[0028] Each oil control valve is only the width of a positioning groove 5, so it is compact. With the connection of the oil passage 3, multiple positioning grooves 5 can be arranged and installed. Furthermore, the oil circuit valve block 1 is not limited to a straight line type. As long as the oil passage 3 is connected, an arc type can also be used. Example
[0029] like Figure 2 , Figure 4 As shown, the oil control valve block 10 is threadedly connected to a plug 15, which connects to the oil chamber 11. A top block 16 is installed in the end region of the piston rod 12, and a spring 17 is installed between the plug 15 and the top block 16. The spring 17 is sleeved on the outside of the end of the piston rod 12.
[0030] In this implementation case, when selecting electromagnet 2, if electromagnet 2 without retraction function is selected, the setting of spring 17 can make electromagnet 2 push piston rod 12 back to its original position to block the input end of oil outlet 8 when the power supply is cut off. Even if electromagnet 2 with retraction function is selected, spring 17 can still achieve the function of assisting retraction because of the oil pressure problem. Moreover, the setting of plug 15 can adjust the elasticity of spring 17 and facilitate the inspection of the internal condition of oil chamber 11. Example
[0031] like Figure 1 , Figure 2 , Figure 4 As shown, the oil control valve block 10 is provided with an air hole 18, which connects to the oil chamber 11. The air hole 18 is located in the area between the first block 13 and the electromagnet 2.
[0032] In this embodiment, the vent 18 can ensure that the movement of the piston rod 12 is not hindered by the vacuum. The specifications of the vent 18 depend on the specific situation, and its position must not be within the range where the first block 13 will interfere, so as to prevent the first block 13 from blocking the vent 18 and thus losing its effect. Example
[0033] like Figure 3 , Figure 5 As shown, rubber rings 19 are installed at both the output end of the oil inlet 7 and the input end of the oil outlet 8.
[0034] In this embodiment, the rubber ring can enhance the sealing effect. To further explain, the rubber ring 19 should not protrude too much from the oil cavity 11, preventing the first block 13 and the second block 14 from moving and rubbing the rubber ring 19 out of the designated installation position. Example
[0035] like Figures 1-4 As shown, both the oil inlet 4 and the oil outlet 9 are threadedly connected to an extension tube 20;
[0036] In this implementation case, the extension tube 20 enhances the overall connectivity, and the threaded connection structure can be adapted to the installation of various sizes of adapters, ensuring normal connection and use.
[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
