Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubricating oil technology, specifically an industrial lubricating oil injection device. Background Technology
[0002] Industrial lubricating oil, known as the "blood" of industrial equipment, is a special type of oil formulated from base oils and additives. It plays a crucial role in various industrial scenarios, reducing friction and wear between equipment parts, extending equipment lifespan, and ensuring the continuity and stability of industrial production.
[0003] The working principle of an industrial lubricating oil injection device is mainly to deliver lubricating oil to the parts that need lubrication according to certain requirements through a specific mechanism or system.
[0004] Existing industrial lubricants are typically injected by squeezing the internal oil onto the parts that need lubrication. However, during use, due to temperature, some solid oil may appear inside the lubricant, causing it to adhere to the inner wall and making it difficult to squeeze out.
[0005] Therefore, an industrial lubricating oil injection device is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An industrial lubricating oil injection device of this utility model includes a support base, with an injection device body fixedly connected to the middle of the support base; an observation window is provided on the surface of the injection device body; a cylinder is fixedly connected to the top of the support base; a round rod is fixedly connected to the output end of the cylinder; an oil outlet plate is fixedly connected to the bottom of the round rod; a pair of rubber blocks are fixedly connected to the end of the oil outlet plate; an air inlet pipe is slidably connected to the top of the injection device body; an air inlet is provided on the surface of the oil outlet plate; the air inlet pipe and the air inlet are interconnected. The system includes: an oil inlet pipe connected to the side wall of the support base; an oil inlet control valve installed in the middle of the oil inlet pipe; an oil outlet pipe opened at the bottom of the oil injection device body; an oil outlet control valve installed in the middle of the oil outlet pipe; and a pressure relief valve installed on the surface of the oil injection device body. By pressing into the interior of the oil injection device body, the oil outlet plate can push the airflow and push the oil together when extruding using the oil outlet plate. This reduces the adhesion of the oil to the inner wall of the oil injection device body through full contact of the airflow, thus reducing separation when pushed and increasing the speed of oil extrusion.
[0008] Preferably, the oil injection device body has a heating cavity inside; multiple heating wires are fixed inside the heating cavity; by adding heating wires, the oil can be heated to increase its fluidity when the oil outlet plate is pushed, making its movement less resistant and thus faster.
[0009] Preferably, the oil injection device body has an internal heat-insulating cavity; the heat-insulating cavity is located outside the heating cavity; a heat-insulating pad is fixed inside the heat-insulating cavity; by adding the heat-insulating pad, the heat loss after the heating wire is heated is slowed down, so that the temperature of the oil inside the oil injection device body is maintained after the heating wire is heated, thus assisting the heating wire in heat preservation after heating.
[0010] Preferably, a pair of baffles are rotatably connected to the end of the oil inlet pipe; the baffles and the oil inlet pipe are connected by a torsion spring; by adding baffles, the middle space can be automatically opened when oil is replenished, and the torsion spring can be used to restore the oil inlet pipe after use, thereby closing the oil inlet pipe and reducing the entry of dust.
[0011] Preferably, a filter plate is fixedly connected to the middle of the oil inlet pipe; the filter plate and the oil inlet pipe are correspondingly arranged; by adding a filter plate, impurities inside the oil can be filtered when replenishing the oil, so that the impurities do not enter the body of the oil injection device.
[0012] Preferably, an ultrasonic detector is fixedly connected inside the oil injection device body; the ultrasonic detector is located at the top of the oil injection device body; by adding an ultrasonic detector, the oil level inside the oil injection device body can be quickly detected, thereby quickly determining whether oil needs to be added during use.
[0013] The advantages of this utility model are:
[0014] 1. The industrial lubricating oil injection device of this utility model can push the oil by pressing the oil outlet plate into the inside of the injection device body. This pushes the oil with the airflow when the oil outlet plate is used for extrusion. The oil is pushed by the full contact of the airflow, thereby reducing the oil adhering to the inner wall of the injection device body. This reduces the separation when the oil is pushed, thereby increasing the speed of oil extrusion.
[0015] 2. The industrial lubricating oil injection device of this utility model can increase the fluidity of the oil by adding a heating wire when the oil outlet plate is pushed, thereby reducing the resistance when it moves and making the pushing faster. Attached Figure Description

[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an industrial lubricating oil injection device includes a support base 1, with an injection device body 11 fixedly connected to the middle of the support base 1; an observation window 12 is provided on the surface of the injection device body 11; a cylinder 13 is fixedly connected to the top of the support base 1; a round rod 14 is fixedly connected to the output end of the cylinder 13; an oil outlet plate 15 is fixedly connected to the bottom of the round rod 14; a pair of rubber blocks 104 are fixedly connected to the end of the oil outlet plate 15; an air inlet pipe 16 is slidably connected to the top of the injection device body 11; and an air inlet 1 is provided on the surface of the oil outlet plate 15. 7; The air inlet pipe 16 and the air inlet 17 are connected; the side wall of the support base 1 is connected to the oil inlet pipe 18; an oil inlet control valve 19 is provided in the middle of the oil inlet pipe 18; an oil outlet pipe 101 is provided at the bottom of the oil injection device body 11; an oil outlet control valve 102 is provided in the middle of the oil outlet pipe 101; a pressure relief valve 103 is installed on the surface of the oil injection device body 11; During operation, the oil is first transferred to the oil injection device body 11 by connecting the oil inlet pipe 18 to the oil pump. At this time, the standard line can be observed through the observation window 12 and then the operation stops. When the oil outlet plate 15 is located at the top of the oil injection device body 11, the oil inlet control valve 19 is closed, causing the oil inlet pipe 18 to stop supplying oil. At this time, the air inlet pipe 16 is connected to the air pump, allowing airflow to enter the air inlet 17 through the air inlet pipe 16 and finally enter the support base 1 for pressurization. After a period of time, the pressurization stops. When oil is needed, the cylinder 13 is started. The cylinder 13 drives the oil outlet plate 15, thereby pushing the internal airflow to move the oil. When the oil outlet plate 15 moves, it will move the rubber block 104, which will then move along the oil injection device body. The inner wall of the body 11 moves, at which time the oil outlet control valve 102 is opened so that the oil can be squeezed out. The oil is squeezed out by air pressure. Whenever oil needs to be replenished, the pressure relief valve 103 can be used to relieve the pressure before replenishment. By pressing into the inside of the oil injection device body 11, the oil outlet plate 15 can push the airflow and push the oil together when it is squeezed by the oil outlet plate 15. Thus, the oil is pushed by the full contact of the airflow, thereby reducing the adhesion to the inner wall of the oil injection device body 11, reducing separation when it is pushed, and increasing the speed of oil extrusion.
[0026] like Figures 2 to 3As shown, a heating cavity 2 is provided inside the oil injection device body 11; multiple heating wires 21 are fixed inside the heating cavity 2; during operation, when the oil outlet plate 15 pushes the oil inside the oil injection device body 11, the heating wires 21 are activated to heat up, and the heat generated by the heating wires 21 diffuses into the interior of the oil injection device body 11, thereby melting the oil adhering to the inner wall of the oil injection device body 11 and accelerating the flow of the oil, thus making it faster to push the oil; by adding heating wires 21, the oil can be heated and its flow can be increased when the oil outlet plate 15 is pushed, so that the resistance when it moves is smaller, thus making it faster to push.
[0027] like Figures 2 to 3 As shown, the oil injection device body 11 has an internal heat-insulating cavity 3; the heat-insulating cavity 3 is located outside the heating cavity 2; a heat-insulating pad 31 is fixed inside the heat-insulating cavity 3; during operation, after the heating wire 21 heats the inside of the heating cavity 2, the internal temperature will diffuse to the surroundings. At this time, the heat-insulating cavity 3 will block the heat diffused outwards, thereby reducing heat loss during use and increasing heat preservation; by adding the heat-insulating pad 31, the heat loss after the heating wire 21 heats up can be slowed down, so that the temperature of the oil inside the oil injection device body 11 after heating can be maintained, thus assisting the heating wire 21 in heat preservation after heating up.
[0028] like Figure 4 As shown, a pair of baffles 4 are rotatably connected to the end of the oil inlet pipe 18; the baffles 4 and the oil inlet pipe 18 are connected by a torsion spring; during operation, the baffles 4 are first pushed to move towards the oil inlet pipe 18 and then oil is added. After the oil is added to the inside of the support base 1 through the oil inlet pipe 18, the baffles 4 will automatically return to their original position by the force of the torsion spring, thus closing the oil inlet pipe 18. In this way, the oil inlet pipe 18 is closed when not in use, thereby blocking dust. By adding baffles 4, the middle space can be automatically made available when oil is added, and the oil inlet pipe 18 can be closed by the torsion spring after use, thereby reducing the entry of dust.
[0029] like Figure 5 As shown, a filter plate 5 is fixedly connected to the middle of the oil inlet pipe 18; the filter plate 5 and the oil inlet pipe 18 are correspondingly arranged; during operation, when replenishing oil inside the oil injection device body 11, the oil passes through the baffle 4 and comes into contact with the filter plate 5 inside the oil inlet pipe 18. At this time, the filter plate 5 will filter the oil and intercept the impurities inside it. Then the oil enters the oil injection device body 11 through the holes on the surface of the filter plate 5; by adding the filter plate 5, impurities inside the oil can be filtered during oil replenishment, preventing impurities from entering the oil injection device body 11.
[0030] like Figure 2As shown, an ultrasonic detector 6 is fixedly installed inside the oil injection device body 11. The ultrasonic detector 6 is located at the top of the oil injection device body 11. During operation, after the oil inside the oil injection device body 11 has been used for a period of time, the ultrasonic detector 6 can be activated. At this time, the ultrasonic detector 6 will emit ultrasonic waves and move towards the oil outlet plate 15. When it comes into contact with the oil outlet plate 15, it bounces back and moves towards the ultrasonic detector 6. Finally, by subtracting the thickness of the oil outlet plate 15 and the distance between the oil and the oil, the oil level can be determined. By adding the ultrasonic detector 6, the oil level inside the oil injection device body 11 can be quickly detected, so it can be quickly determined whether oil needs to be added during use.
[0031] Working principle: First, the oil inlet pipe 18 is connected to the oil pump to transmit oil to the oil injection device body 11. At this time, the flow rate is observed through the observation window 12 and then stopped. At this time, the oil outlet plate 15 is located at the top of the oil injection device body 11. Then, the oil inlet control valve 19 is closed to stop the oil inlet pipe 18 from delivering oil. At this time, the air inlet pipe 16 is connected to the air pump, so that the airflow enters the air inlet 17 through the air inlet pipe 16 and finally enters the support base 1 for pressurization. After a period of time, it stops. When oil is needed, the cylinder 13 is started. The cylinder 13 drives the oil outlet plate 15, thereby pushing the internal airflow. The oil moves, and when the oil outlet plate 15 moves, it drives the rubber block 104 to move along the inner wall of the oil injection device body 11. At this time, the oil outlet control valve 102 is opened, allowing the oil to be squeezed out. The oil is squeezed out using air pressure. Whenever oil needs to be replenished, the pressure relief valve 103 can be used to release pressure before replenishment. When the oil outlet plate 15 pushes the oil inside the oil injection device body 11, the heating wire 21 is activated, causing it to heat up. The heat generated by the heating wire 21 then diffuses into the interior of the oil injection device body 11, melting the oil adhering to the inner wall of the oil injection device body 11. The increased fluidity of the oil allows for faster propulsion of the oil. After the heating wire 21 heats the interior of the heating cavity 2, the internal temperature diffuses outwards. The insulation cavity 3 then blocks this outward heat diffusion, reducing heat loss during use and increasing insulation. First, the baffle 4 is pushed towards the oil inlet pipe 18 to replenish the oil. After replenishing the support base 1 with oil through the oil inlet pipe 18, the baffle 4 automatically returns to its original position via the force of the torsion spring, closing the oil inlet pipe 18. This closes the oil inlet pipe 18 when not in use, preventing dust accumulation. This process is similar to the process for the oil filling device. When replenishing oil inside the body 11, the oil passes through the baffle 4 and comes into contact with the filter plate 5 inside the oil inlet pipe 18. At this time, the filter plate 5 will filter the oil and intercept the impurities inside. Then, the oil enters the body 11 of the oil filling device through the holes on the surface of the filter plate 5. After the oil inside the body 11 of the oil filling device has been used for a period of time, the ultrasonic detector 6 can be activated. At this time, the ultrasonic detector 6 will emit ultrasonic waves and move towards the oil outlet plate 15. When it comes into contact with the oil outlet plate 15, it bounces back and moves towards the ultrasonic detector 6. Finally, the oil level can be determined by the movement time and the thickness of the oil outlet plate 15 and the distance of the oil.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
