Description

Technical Field

[0001] This utility model relates to the field of grease application technology, and in particular to a grease application device for air compressor maintenance. Background Technology

[0002] The air compressor grease applicator is a device specifically designed to provide grease application services for critical components such as air compressor bearings. It aims to solve problems such as grease buildup and spillage, and uneven application that often occur with traditional lubrication methods. Through optimized design, it achieves precise grease application, ensuring even coverage of lubricated areas and effectively preventing over- or under-lubrication, thereby improving grease utilization and reducing waste.

[0003] A search revealed Chinese patent publication number CN217784812U, which discloses a grease application device for air compressor maintenance. The device includes a support plate, a fixed rod fixedly connected to one side of the top surface of the support plate, an operating rod rotatably connected to the top of the fixed rod, and a cylinder rotatably connected to the middle of the top surface of the support plate. The device uses a filling assembly comprising an outer conical shell, an inner conical shell, and six supporting protrusions. These six protrusions are welded to the inner wall of the outer conical shell and the outer wall of the inner conical shell, creating a gap between them. The filling assembly is connected to the cylinder via a connecting pipe, which in turn connects the connecting plate to the air compressor. The device is then aligned with and pressed against the bearing to fill the cylinder with grease. Pressing down the operating rod allows the grease to evenly enter the bearing along the connecting pipe and the filling assembly, preventing grease buildup and improving grease utilization.

[0004] The aforementioned patent mentions the beneficial effects of: "The filling assembly includes an outer conical shell, an inner conical shell, and six supporting protrusions. The six supporting protrusions are fixedly connected to the inner wall of the outer conical shell and the outer wall of the inner conical shell by welding, thus leaving a certain gap between the outer and inner conical shells. The filling assembly is connected to a cylinder through a connecting pipe, thereby fixing the connecting plate to the air compressor. The filling assembly is aligned with the bearing and pressed down to fill the cylinder with grease. Then, the operating lever is pressed down, so that the grease is evenly injected into the bearing along the connecting pipe and the filling assembly, avoiding grease accumulation and improving grease utilization." However, since the outer conical shell, inner conical shell, and supporting protrusions are fixed by welding, if different specifications of air compressor bearings need to be adapted, the entire filling assembly needs to be replaced, which not only increases the cost of spare parts procurement but also prolongs maintenance time. Moreover, when the filling assembly is partially worn or blocked, it is difficult to disassemble and replace the vulnerable parts individually, and the entire assembly must be replaced, resulting in resource waste. Therefore, an air compressor maintenance grease application device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an air compressor maintenance grease application device, which solves the problem that it is difficult to disassemble and replace vulnerable parts individually, and that the entire unit must be replaced.

[0006] To achieve the above objectives, this utility model provides an air compressor maintenance grease application device, including a base plate, a cylinder rotatably connected to the top of the base plate, a connecting pipe fixedly connected to the outer wall of the cylinder, a disassembly mechanism installed at the other end of the connecting pipe, a support plate two fixedly connected to the top of the base plate, an adjustment mechanism installed on the outer wall of the support plate two, and a filling nozzle detachably connected to the inner wall of the disassembly mechanism. The disassembly mechanism includes a connecting plate, the left end of which is fixedly connected to the right end of the connecting tube. A pressing rod is slidably connected to the inner wall of the connecting plate, and a wedge is fixedly connected to the bottom end of the pressing rod. A support plate is fixedly connected to the inner wall of the connecting plate, and a connecting rod is fixedly connected to the bottom end of the wedge. A spring is sleeved on the outer wall of the connecting rod. A turntable is rotatably connected to the inner wall of the connecting plate, and three wedges are fixedly connected to the inner wall of the turntable. A reset assembly is slidably connected to the inner wall of the connecting plate.

[0007] The reset assembly includes three sliding blocks, the left ends of which are slidably connected to the inner wall of the connecting plate. Three guide rods are fixedly connected to the inner wall of the connecting plate, and springs are sleeved on the outer walls of the guide rods. Three guide plates are fixedly connected to the inner wall of the connecting plate, and inclined blocks are fixedly connected to the outer walls of the three sliding blocks.

[0008] The adjusting mechanism includes a sliding plate, the inner wall of which is slidably connected to the outer wall of the support plate, a fixed rod slidably connected to the inner wall of the sliding plate, a circular plate fixedly connected to the front end of the fixed rod, a fixed plate fixedly connected to the outer wall of the fixed rod, a spring three sleeved on the outer wall of the fixed rod, a support rod fixedly connected to the top end of the sliding plate, and a fixed block rotatably connected to the top end of the support rod.

[0009] The inner wall of the second support plate is rotatably connected to an operating rod, and the top of the first inclined block is in contact with the inner wall of the turntable.

[0010] The outer wall of the connecting rod is slidably connected to the inner wall of the support plate, one end of the spring is fixedly connected to the top of the support plate, and the other end of the spring is fixedly connected to the bottom of the inclined block.

[0011] The inner wall of the sliding block is slidably connected to the outer wall of the guide plate, and the side of the inclined block two that is close to the side of the inclined block three that is far from the other side is in contact.

[0012] The inner wall of the sliding block is slidably connected to the outer wall of the guide rod, one end of the second spring is fixedly connected to the inner wall of the connecting plate, and the other end of the second spring is fixedly connected to the outer wall of the sliding block.

[0013] The fixed rod is slidably connected to the inner wall of the second support plate, one end of the third spring is fixedly connected to the inner wall of the sliding plate, and the other end of the third spring is fixedly connected to the front end of the fixed plate.

[0014] This utility model relates to an air compressor maintenance lubricating grease application device. 1. In this utility model, pressing the pressing rod causes the inclined block to move down and compress the first spring, releasing the limit on the turntable. Rotating the turntable causes the second inclined block to disengage from the third inclined block, and the second spring causes the sliding block to reset and unlock, realizing convenient disassembly of the connecting pipe and related components. Different specifications of filling nozzles can be quickly switched, which is compatible with various bearings of air compressors. There is no need to replace the entire filling assembly, which greatly shortens maintenance time. It is especially efficient when maintaining multiple devices in batches. After the filling nozzle is worn or blocked, it can be quickly replaced individually without discarding the entire assembly, reducing spare parts costs and resource waste.

[0015] 2. In this utility model, by pulling the circular plate, the fixed rod and the fixed plate compress the spring three, so that the sliding plate is adjusted along the support plate. When the circular plate is released, the spring three returns to its original position, so that the fixed rod is inserted into the support plate to fix the sliding plate. When the operating rod moves, the fixing block at the top of the support rod contacts it to limit the stroke of the operating rod. By preset the downward stroke of the operating rod, the amount of grease injected at one time can be accurately controlled within the range required by the bearing. This avoids the problems of "over-injection of grease contaminating the equipment" or "under-injection of grease causing bearing wear" caused by manual operation based on feel. It greatly improves the lubrication accuracy and does not rely on the operator's experience. Novices only need to adjust to the corresponding stroke according to the scale, which lowers the operation threshold and is especially suitable for multi-person rotation or batch standardized maintenance scenarios.

The left ends of the three sliding blocks 491 are slidably connected to the inner wall of the connecting plate 41. The reset assembly 49 uses the three sliding blocks 491 as the core actuating component. The inner wall of the connecting plate 41 provides a sliding track for the sliding blocks 491, limiting their radial movement direction and ensuring that the sliding blocks 491 move smoothly without deviation. Three guide rods 492 are fixedly connected to the inner wall of the connecting plate 41. The connecting plate 41 provides fixed support for the guide rods 492, ensuring their position is correct. It is said that the outer wall of the guide rod 492 is fitted with a second spring 493, and the guide rod 492 limits the deformation direction of the second spring 493 to prevent the second spring 493 from twisting. The inner wall of the connecting plate 41 is fixedly connected with three guide plates 494, and the connecting plate 41 provides a fixed foundation for the guide plates 494 to ensure that they are compatible with the sliding block 491. The outer wall of the three sliding blocks 491 is fixedly connected with a third inclined block 495. When the sliding block 491 moves, it drives the third inclined block 495 to move synchronously and cooperate with the second inclined block 48. Reference Figure 2 , Figure 4 and Figure 5The adjusting mechanism 6 includes a sliding plate 61, the inner wall of which is slidably connected to the outer wall of the support plate 5.

Reference Figures 3 to 5 The inner wall of support plate 2 5 is rotatably connected to operating rod 7. Support plate 2 5 provides rotational support for operating rod 7, limiting the rotation trajectory of operating rod 7 and ensuring its smooth rotation. The top of inclined block 1 43 contacts the inner wall of turntable 47. Inclined block 1 43 limits turntable 47 by contacting turntable 47 with its top, preventing turntable 47 from rotating arbitrarily. The outer wall of connecting rod 45 is slidably connected to the inner wall of support plate 1 44. Support plate 1 44 provides sliding guide for connecting rod 45, limiting the direction of movement of connecting rod 45 and preventing it from deviating. One end of spring 1 46 is fixed. The spring 46 is connected to the top of the support plate 44, and the other end of the spring 46 is fixedly connected to the bottom of the inclined block 43. One end of the spring 46 is fixed to the top of the support plate 44, and the other end is fixed to the bottom of the inclined block 43. The support plate 44 provides a fixed support point for the spring 46 to ensure that the spring 46 is stable under force when it deforms, and realizes the automatic reset of the inclined block 43. The inner wall of the sliding block 491 is slidably connected to the outer wall of the guide plate 494. The guide plate 494 provides sliding guidance for the sliding block 491, further limiting the movement trajectory of the sliding block 491 and enhancing its sliding stability. The side of inclined block 2 48 that is close to the side of inclined block 3 495 that is far from the side of inclined block 3 495 is in contact when inclined block 2 48 rotates. When inclined block 2 48 rotates, it presses against inclined block 3 495 through the inclined surface, pushing sliding block 491 to move and lock it. The inner wall of sliding block 491 is slidably connected to the outer wall of guide rod 492. Guide rod 492 provides sliding support for sliding block 491 and limits the radial movement trajectory of sliding block 491. One end of spring 2 493 is fixedly connected to the inner wall of connecting plate 41, and the other end of spring 2 493 is fixedly connected to the outer wall of sliding block 491. One end of spring 2 493 is fixed to the inner wall of connecting plate 41, and the other end is fixed to the outer wall of sliding block 491. Connecting plate 41 provides a fixed support for spring 2 493. The reference ensures that the force is uniform when the second spring 493 deforms. The fixed rod 62 is slidably connected to the inner wall of the second support plate 5. The second support plate 5 provides an insertion channel for the fixed rod 62. The position of the sliding plate 61 is fixed by cooperating with the fixed rod 62. One end of the third spring 65 is fixedly connected to the inner wall of the sliding plate 61, and the other end of the third spring 65 is fixedly connected to the front end of the fixed plate 64. One end of the third spring 65 is fixed to the inner wall of the sliding plate 61, and the other end is fixed to the front end of the fixed plate 64. The sliding plate 61 provides fixed support for the third spring 65 to ensure that the force is stable when the third spring 65 deforms. The third spring 65 drives the fixed rod 62 to rebound and insert into the second support plate 5 through the moving fixed plate 64.

[0021] Working principle: By pressing the pressing rod 42, it slides along the inner wall of the connecting plate 41, causing the bottom inclined block 43 to move down. The inclined block 43 pushes the connecting rod 45 to compress the spring 46, releasing the limit on the turntable 47. When the turntable 47 is rotated, the three inclined blocks 48 on its inner wall rotate together, disengaging from the contact with the inclined block 495 in the reset assembly 49. The spring 493 on the guide rod 492 on the inner wall of the connecting plate 41 rebounds, causing the sliding block 491 to slide and reset along the inner wall of the connecting plate 41. The guide plate 494 ensures that the sliding block 491 moves smoothly. Release the pressing rod 42, and spring 46 drives the inclined block 43 to reset and reposition the turntable 47, completing the disassembly action. Through mechanical transmission and spring reset, the filling nozzle 8 can be quickly disassembled and assembled. When fixing is required, press the pressing rod 42, and the inclined block 43 will disengage from the turntable 47. Rotate the turntable 47 so that the inclined surface of the inclined block 48 contacts the inclined surface of the inclined block 495, pushing the sliding block 491 to move along the guide plate 494. Spring 493 generates a reset force through elastic deformation. After fixing is completed, release the pressing rod 42, and spring 46 drives the inclined block 43 to fix the turntable 47, thus fixing the filling nozzle 8.

[0022] By pulling the circular plate 63, the fixed rod 62 and the fixed plate 64 on the outer wall move synchronously, compressing the spring 65 on the fixed rod 62, causing the fixed rod 62 to disengage from the support plate 5, releasing the fixation on the sliding plate 61. The sliding plate 61 can then slide along the support plate 5 to the desired position. After releasing the circular plate 63, the spring 65 returns to its original position, pushing the fixed plate 64 and the fixed rod 62 back to spring back. The fixed rod 62 then inserts into the support plate 5 to fix the position of the sliding plate 61. The support rod 66 at the top of the sliding plate 61 supports a rotatable fixed block 67. The fixed block 67, through contact with the operating rod 7, can adjust the stroke of the operating rod 7 as needed, achieving a dual adjustment function of position and stroke.

[0023] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
