Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil distributors, specifically a progressive lubricating oil distributor. Background Technology

[0002] A progressive distributor is a device that uses pressure to drive a piston to quantitatively distribute lubricant. Its core structure consists of a starting plate, a ending plate, and multiple intermediate plates. In a single-line progressive dry oil centralized lubrication system, this distributor, with its precise quantitative distribution characteristics, is widely used in lubrication scenarios for heavy-duty equipment in metallurgy, mining, and construction machinery. The nominal pressure can reach 16MPa. According to the design type, it can be divided into plate type and block type. The plate type distributor adopts a modular structure, which supports flexible combination and expansion. Users can freely increase or decrease the number of intermediate plates according to the actual number of lubrication points required, which has strong system adaptability and solution flexibility.

[0003] However, existing plate-type distributors suffer from complex connection structures or cumbersome operations between the plates, requiring more time for plate alignment and fixing, thus affecting the overall progress of equipment installation and commissioning. Furthermore, inconvenient connections may lead to insufficient sealing, resulting in leakage or uneven distribution of lubricating oil during the distribution process, affecting the lubrication effect and service life of the equipment. Therefore, we propose a progressive lubricating oil distributor to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a progressive lubricating oil distributor to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a progressive lubricating oil distributor, comprising a starting plate, a terminating plate, and multiple intermediate plates. The upper surfaces of the starting plate, the terminating plate, and the intermediate plates are provided with multiple sets of connecting components. Each set of connecting components includes a groove, a first spring, two sliding grooves, a rotating plate, a cavity, a second spring, a pressing block, a support plate, and two sliding rods.

[0006] In a further embodiment, the outer surface of the starting piece is connected to an oil inlet pipe, and the outer surface of each intermediate piece is connected to two oil outlet pipes.

[0007] In a further embodiment, a rubber gasket is connected to the inner wall of the oil inlet pipe, and the inner wall of the oil inlet pipe is provided with internal threads.

[0008] In a further embodiment, a first spring is connected to the inner wall of each groove, and two sliding grooves are formed on the inner wall of each groove.

[0009] In a further embodiment, the inner wall of each groove is hinged to a rotating plate by a pin, and the outer surface of each rotating plate is provided with a cavity.

[0010] In a further embodiment, a second spring is connected to the inner wall of each cavity, and a pressing block is connected to the top of each second spring.

[0011] In a further embodiment, a support plate is connected to the upper surface of each pressing block, and two slide rods are connected to the outer surface of each support plate, each slide rod being adapted to a slide groove.

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

[0013] 1. The design of the connecting components allows for efficient and rapid assembly of the starting plate, ending plate, and intermediate plates. The elastic support of the first and second springs ensures a tight fit between the plates, maintaining a stable connection even under 16MPa high pressure conditions. This prevents the plates from loosening due to vibration or pressure fluctuations. Furthermore, when an intermediate plate requires maintenance, there is no need for complete disassembly, reducing maintenance time and costs. The use of rubber gaskets and internal threads effectively prevents lubricant leakage, while the internal thread structure facilitates quick connection with external pipelines, improving installation efficiency.

[0014] 2. By setting up a cavity, a second spring, a pressing block, a support plate, and a sliding rod, when a certain intermediate piece needs to be removed, pressing the pressing block compresses the second spring, and the sliding rod slides along the slide groove to drive the rotating plate to unlock, allowing the target piece to be removed individually without overall disassembly. The elastic support of the first and second springs ensures that the pieces remain tightly fitted under MPa high pressure and vibration conditions, ensuring that the distributor operates reliably for a long time under high pressure and avoiding abnormal lubricating oil distribution caused by loose pieces.

[0021] 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.

[0022] Example: Figures 1-5 As shown, this utility model provides a technical solution for a progressive lubricating oil distributor, including a starting plate 1, a ending plate 2, and multiple intermediate plates 3. Multiple sets of connecting components 8 are formed on the upper surfaces of the starting plate 1, the ending plate 2, and the intermediate plates 3. Each connecting component 8 includes a groove 801, a first spring 802, two sliding grooves 803, a rotating plate 804, a cavity 805, a second spring 806, a pressing block 807, a support plate 808, and two sliding rods 809. Through the design of the connecting components 8, the starting plate can be effectively connected... 1. The termination piece 2 and the intermediate piece 3 are quickly assembled. The elastic support of the first spring 802 and the second spring 806 ensures that the pieces fit tightly together, maintaining a stable connection even under 16MPa high pressure conditions. This prevents the pieces from loosening due to vibration or pressure fluctuations. At the same time, when an intermediate piece 3 needs maintenance, there is no need to disassemble the whole piece, reducing maintenance time and costs. The rubber gasket 6 and the internal thread 7 work together to effectively prevent lubricating oil leakage. The internal thread 7 structure facilitates quick connection with external pipelines, improving installation efficiency.

[0023] By setting the groove 801, the first spring 802, the rubber gasket 6 and the internal thread 7 to cooperate with each other, a high-pressure stable connection, efficient maintenance and leakage prevention are achieved. The first spring 802 provides a continuous axial clamping force, which makes the gap between the plate mating surfaces smaller. The self-locking structure composed of the rotating plate 804 and the slide rod 809 greatly improves the disassembly time of a single module, extends the service life of the distributor in the high-pressure system and reduces maintenance costs.

[0024] like Figure 4 and Figure 5As shown, the first spring 802 and the second spring 806 of the connecting component 8 keep the plates tightly fitted under a high pressure of 16MPa, preventing loosening due to vibration or pressure fluctuations and ensuring the structural integrity of the distributor. The rotating plate 804 and the sliding groove 803 of the connecting component 8 enable the rapid assembly and disassembly of the starting plate 1, the ending plate 2 and the intermediate plate 3.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the outer surface of the starting plate 1 is connected to an oil inlet pipe 4, and the outer surface of each intermediate plate 3 is connected to two oil outlet pipes 5. A rubber gasket 6 is connected to the inner wall of the oil inlet pipe 4, and an internal thread 7 is provided on the inner wall of the oil inlet pipe 4. The internal thread 7 allows for quick connection to an external pipe, ensuring that the top of the external pipe contacts the rubber gasket 6, preventing lubricant leakage, extending equipment lifespan, and reducing mechanical wear caused by poor lubrication. A first spring 802 is connected to the inner wall of each groove 801, and two sliding grooves 803 are provided on the inner wall of each groove 801. The inner wall of each groove 801 is hinged by a pin. The rotating plate 804 has a cavity 805 on its outer surface. A second spring 806 is connected to the inner wall of each cavity 805. A pressing block 807 is connected to the top of each second spring 806. A support plate 808 is connected to the upper surface of each pressing block 807. Two sliding rods 809 are connected to the outer surface of each support plate 808. Each sliding rod 809 is adapted to the sliding groove 803. Through the cooperation of various structures, the starting piece 1, the ending piece 2 and the intermediate piece 3 can be quickly installed and disassembled, ensuring that each piece is stably connected and sealed. This is beneficial to the long-term use of the device and reduces the maintenance cost of the device.

[0026] By setting up rubber gasket 6, rotating plate 804, support plate 808 and slide bar 809 in cooperation, quick disassembly and assembly, high-pressure sealing and long service life are achieved. The oil inlet pipe 4 cooperates with rubber gasket 6 to reduce leakage rate under oil pressure, reducing leakage risk compared with traditional flange connection. The guide rail structure of rotating plate 804 and slide bar 809 enables one-handed operation, reduces the disassembly and assembly time of single module, and improves efficiency compared with bolt connection. Through the synergistic innovation of fluid sealing and mechanical structure, the failure rate of production line lubrication system is greatly reduced in the actual application of automobile manufacturing, and the annual maintenance cost is also greatly reduced.

[0027] like Figure 4 and Figure 5As shown, through the cooperation of cavity 805, second spring 806, pressing block 807, support plate 808 and slide rod 809, when a certain intermediate piece 3 needs to be disassembled, pressing the pressing block 807 compresses the second spring 806, and the slide rod 809 slides along the slide groove 803 to drive the rotating plate 804 to unlock, so that the target piece can be disassembled separately without overall disassembly. The elastic support of the first spring 802 and the second spring 806 ensures that the pieces always keep in close contact under 16MPa high pressure and vibration conditions, ensuring that the distributor can operate reliably for a long time under high pressure environment and avoiding abnormal lubricating oil distribution caused by loose pieces.

[0028] The working principle of this utility model is as follows:

[0029] When using this device, the starting piece 1, the ending piece 2, and the intermediate piece 3 must first be precisely aligned with each other, as this ensures the accuracy and stability of subsequent operations. After aligning these pieces, the pressing operation is next. The user first presses the support plate 808, at which point the pressing block 807 is pushed and retracted under the action of the second spring 806. The second spring 806 provides a certain elastic force to control the retraction speed and force of the pressing block 807, thereby ensuring the smooth retraction of the device. At this time, the rotating plate 804 connected by the pin begins to rotate. The rotation of the rotating plate 804 causes compression of the first spring 802. During the compression process, the first spring 802 generates a certain elastic force, and after compression, it retracts, thereby pushing the slide rod 809 to slide downwards, eventually causing the slide rod 809 to reach the bottom of the slide groove 803. At this point, all mechanical parts are in a ready-to-operate state.

[0030] After this, releasing the support plate 808 will cause the second spring 806 to cause the pressing block 807 to rebound. During the rebound process, the second spring 806 pushes the pressing block 807 back to the initial position, so that the slide bar 809 slides again under the action of the rebound force. The movement of the slide bar 809 becomes more stable and controllable, ensuring that the support plate 808 can slide smoothly in the slide groove 803. When the sliding process is over, the first spring 802 will rebound due to its own elasticity and support the support plate 808. This rebound process can effectively prevent the support plate 808 from shaking after the operation is completed, ensuring the stability and accuracy of the device. The support plate 808 remains stable under the rebound action of the first spring 802, avoiding the impact of shaking on the overall performance of the device.
