Description
Technical Field
[0001] This utility model relates to the field of work technology, and in particular to a handheld intelligent precision lubricating grease dispenser. Background Technology
[0002] In modern industrial production, lubrication and maintenance of mechanical equipment is a key link to ensure its normal operation and extend its service life. Handheld intelligent precision lubricating grease dispensers are widely used in many fields such as automobile repair, machinery manufacturing, and power facility maintenance due to their portability, operational flexibility and dispensing accuracy. Whether it is micro-lubrication of precision instruments or batch dispensing of bearings of large equipment, these devices can respond quickly to needs and have become an indispensable tool for equipment maintenance personnel.
[0003] Currently, most handheld grease dispensers on the market use a threaded connection between the oil tank and the main body. This means the oil tank is screwed onto the dispenser body. However, the disassembly and assembly process of the threaded connection is quite cumbersome. Maintenance personnel need to rotate the oil tank multiple times to complete the disassembly or installation. This is especially time-consuming and labor-intensive in scenarios where grease dispensing is frequent and the oil tank needs to be replaced frequently, greatly reducing work efficiency. With increased use, the threads are prone to wear and stripping, leading to gaps between the oil tank and the main body and causing grease leakage. Once grease leaks, it not only wastes lubricating materials and increases usage costs, but also pollutes the working environment. It may even cause equipment failure or safety hazards if grease drips onto the moving parts of the equipment. Utility Model Content

This solves the problem that the disassembly and assembly process of threaded connections is cumbersome, requiring maintenance personnel to rotate the oil tank multiple times to complete the disassembly or installation. This is especially time-consuming and labor-intensive in scenarios where grease filling is frequent and the oil tank needs to be replaced frequently, which greatly reduces work efficiency. With the increase of use, the threads are prone to wear and stripping, resulting in gaps between the oil tank and the main body, causing grease leakage. Once grease leaks, it will not only waste lubricating materials and increase usage costs, but also pollute the working environment.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a handheld intelligent precision lubricating grease dispenser, including an electric grease gun body 1, a battery assembly 2, a spiral extrusion self-priming pump 3, and an oil suction pipe 5;
[0031] A limit component is provided on the main body 1 of the electric grease gun;
[0032] The limiting assembly includes an oil tank 4 and two protective shells 7. Both protective shells 7 are fixedly connected to the outer walls on both sides of the front end connection of the electric grease gun body 1. An oil tank mounting groove 13 is provided at the front end connection of the electric grease gun body 1. The upper outer wall of the oil tank 4 is slidably connected to the interior of the oil tank mounting groove 13. Two sliding rods 6 are slidably connected to the outer walls of both protective shells 7. First limiting block grooves 14 are provided on both sides of the inner walls of the oil tank mounting groove 13. Limiting blocks 15 are slidably connected inside the two first limiting block grooves 14. Second limiting block grooves 16 are provided on both sides of the upper outer walls of the oil tank 4. The ends of the two limiting blocks 15 near the second limiting block grooves 16 slidably extend into the interior of the oil tank mounting groove 13 and are slidably connected to the interior of the corresponding second limiting block grooves 16. A sealing ring 11 is installed on the upper outer wall of the oil tank 4. The outer wall of the sealing ring 11 contacts the inner wall of the oil tank mounting groove 13. The protective shell 7 has push block grooves 10 on both outer walls. Push blocks 8 are slidably connected inside the four push block grooves 10. The interiors of the two first limiting block grooves 14 are respectively connected to the interiors of the corresponding push block grooves 10. The ends of the four push blocks 8 near the limiting blocks 15 are slidably extended into the interiors of the first limiting block grooves 14 and are respectively fixedly connected to the outer walls of the corresponding limiting blocks 15. Limiting blocks 9 are slidably engaged inside the four push block grooves 10. The outer walls of the four limiting blocks 9 at both ends are respectively in contact with the inner walls of the corresponding push block grooves 10 and one side of the outer wall of the push block 8. The ends of the four slide rods 6 near the limiting blocks 15 are slidably extended into the interiors of the first limiting block grooves 14 and are respectively fixedly connected to the outer walls of the corresponding limiting blocks 15. Return springs 12 are sleeved on the outer walls of the four slide rods 6. The two ends of the four return springs 12 are respectively fixedly connected to the inner walls of the corresponding first limiting block grooves 14 and the outer walls of the limiting blocks 15.
[0033] The battery assembly 2 is installed below the handle on the main body 1 of the electric grease gun. The main body 1 of the electric grease gun is electrically connected to the battery assembly 2. The screw extrusion self-priming pump 3 is installed on the upper end of the main body 1 of the electric grease gun. The main body 1 of the electric grease gun is electrically connected to the screw extrusion self-priming pump 3. The oil suction pipe 5 is installed on the upper surface of the front end of the main body 1 of the electric grease gun. The oil storage tank 4 is connected to the oil suction pipe 5 through the main body 1 of the electric grease gun. An electric heating wire is installed inside the oil suction pipe 5. A liquid level sensor is installed inside the oil storage tank 4.
[0034] Furthermore, when using this device, first align the upper end of the oil tank 4 with the oil tank mounting groove 13 of the electric grease gun body 1, and slowly insert it. At this time, the second limiting block groove 16 on both sides of the upper end of the oil tank 4 corresponds to the first limiting block groove 14 on both sides of the inner wall of the oil tank mounting groove 13. The force generated by the return spring 12 on the pushing block 8 causes the pushing block 8 to slide in the pushing block groove 10, driving the limiting block 15 fixedly connected to it to slide along the first limiting block groove 14, so that the limiting block 15 slides into the second limiting block groove 14 of the oil tank 4. Within the slot 16, the limiting block 15 restricts the movement of the oil tank 4, firmly fixing it to the electric grease gun body 1. Simultaneously, the sealing ring 11 on the upper outer wall of the oil tank 4 is in close contact with the inner wall of the oil tank mounting groove 13, ensuring a tight seal after installation. After the oil tank 4 is installed, the battery assembly 2 supplies power to the electric grease gun body 1 and the spiral extrusion self-priming pump 3, starting the electric grease gun body 1. The spiral extrusion self-priming pump 3 then begins operation, generating suction through spiral extrusion to draw the grease from the oil tank 4. The lubricating grease is drawn in through the suction pipe 5. Inside the suction pipe 5, if the ambient temperature is low, the electric heating wire can heat the grease, reducing its viscosity and facilitating its flow. The pressurized grease is then delivered through the suction pipe 5 to the part requiring lubrication, achieving precise dispensing. When the oil storage tank 4 needs to be disassembled for replacement, the handle on the limiting block 9 on the outer wall of the protective shell 7 is manually pulled outward to remove it from the inside of the push block groove 10. Then, the push block 8 is pushed, causing the limiting block 15 to slide within the first limiting block groove 14, thus... The limiting block 15 disengages from the second limiting block groove 16 of the oil storage tank 4, causing the limiting block 15 to move away from the oil storage tank 4. The oil storage tank 4 loses its limiting position, and the oil storage tank 4 can be pulled upward from the oil storage tank mounting groove 13 to perform or replace the operation. At the same time, during the entire use process, the liquid level sensor in the oil storage tank 4 monitors the remaining grease in real time and feeds the data back to the electric grease gun body 1 so that the operator can know the grease level in time and replenish it when the grease is insufficient, ensuring the normal operation of the handheld intelligent precision lubricating grease dispenser.
[0035] By pushing the pusher block 8 in the limiting component, the pusher block 8 causes the limiting block 15 to slide in the first limiting block groove 14, so that the limiting block 15 disengages from the second limiting block groove 16 of the oil storage tank 4, and moves the limiting block 15 away from the oil storage tank 4. The oil storage tank 4 loses its limiting position, and the oil storage tank 4 can be pulled upward from the oil storage tank mounting groove 13 to perform or replace the operation. This disassembly of the oil storage tank 4 is simple and quick, reducing the workload of the staff and avoiding the wear of the threads due to the increase in the number of uses, thereby effectively improving the practicality and reliability of the equipment.

At the same time, the internal circuitry enables electrical connection with the battery assembly 2 and the screw extrusion self-priming pump 3. It serves as the carrier for the installation and operation of other components and provides the main framework for the operation and control of the grease dispenser.
[0037] Battery assembly 2: Installed below the handle of the electric grease gun body 1, electrically connected to the electric grease gun body 1, providing power support for the electric grease gun body 1, the spiral extrusion self-priming pump 3, and the electric heating wire in the oil suction pipe 5, and is the power source for the operation of the entire dispenser.
[0038] Screw extrusion self-priming pump 3: Installed on the upper end of the electric grease gun body 1 and electrically connected to the electric grease gun body 1. When working, it draws in the lubricating grease in the oil storage tank 4 through screw extrusion and pressurizes it for output, realizing the grease delivery function. It is the key power component for the dispenser to achieve accurate grease dispensing.
[0039] Oil storage tank 4: The upper outer wall is slidably connected to the oil storage tank mounting groove 13 of the electric grease gun body 1, and is used to store lubricating grease. A liquid level sensor is installed inside to monitor the remaining amount of grease in the oil storage tank in real time. The upper two outer walls are provided with second limit block grooves 16, which are used to cooperate with limit blocks 15 to achieve fixation. The sealing ring 11 installed on the upper outer wall is in contact with the inner wall of the oil storage tank mounting groove 13 to ensure the sealing of the oil storage tank after installation and prevent grease leakage.
[0040] Oil suction pipe 5: Installed on the upper front surface of the electric grease gun body 1. One end is connected to the oil storage tank 4 through the electric grease gun body 1, and the other end is used to suck and transport grease. It is equipped with an electric heating wire inside, which can heat the grease in low temperature environment, reduce the viscosity of the grease, and facilitate the transport and filling of grease.
[0041] Slide rod 6: Two slide rods 6 are slidably connected to the outer wall of each protective shell 7, for a total of four. One end of the slide rod 6 extends slidably into the first limiting block groove 14 and is fixedly connected to the outer wall of the limiting block 15. The other end slides on the outer wall of the protective shell 7. The slide rod 6 provides guidance for the sliding of the limiting block 15, ensuring that the limiting block 15 will not deviate during the sliding process. At the same time, it bears the elastic force of the return spring 12 and maintains the mechanical balance of the limiting component.
[0042] Protective shell 7: Two protective shells 7 are fixedly connected to the outer walls on both sides of the front end connection of the electric grease gun body 1, which serves to protect the internal components such as slide rod 6, limit block 15, and return spring 12. The outer wall is provided with a sliding channel for slide rod 6, and the outer walls on both sides are provided with push block groove 10 and first limit block groove 14 to provide sliding space and installation position for push block 8 and limit block 15.
[0043] Pushing block 8: Four pushing blocks 8 slide in four pushing block slots 10 respectively, with one end extending into the first limiting block slot 14 and fixedly connected to the outer wall of the limiting block 15. By manually pushing the pushing blocks 8, the operator can drive the limiting block 15 to slide in the first limiting block slot 14 and the second limiting block slot 16, thereby controlling the limiting state of the oil storage tank 4.
[0044] Limiting blocks 9: Four limiting blocks 9 are slidably engaged in the four pushing block slots 10 respectively, with their two ends contacting the inner wall of the pushing block slot 10 and the outer wall of one side of the pushing block 8 respectively. They are used to limit the sliding range of the pushing block 8, prevent the pushing block 8 from disengaging from the pushing block slot 10 during the sliding process, and ensure the structural integrity and functional reliability of the limiting component.
[0045] Sealing ring 11: Installed on the upper outer wall of oil storage tank 4, its outer wall is in close contact with the inner wall of oil storage tank mounting groove 13 to form a sealing structure, preventing the lubricating grease in oil storage tank 4 from leaking during installation and use, and ensuring the sealing of the filler and the cleanliness of the grease;
[0046] Reset spring 12: Four reset springs 12 are respectively sleeved on the outer wall of four slide rods 6, and their two ends are fixedly connected to the inner wall of the first limiting block groove 14 and the outer wall of the limiting block 15 respectively. In the natural state, the reset spring 12 is in a compressed or stretched state, providing the limiting block 15 with the elastic force for reset. When the pushing block 8 pushes the limiting block 15 away from the second limiting block groove 16, the pushing block 8 is released, and the elastic force of the reset spring 12 will cause the limiting block 15 to automatically slide back into the second limiting block groove 16, thereby realizing the automatic limiting of the oil tank 4.
[0047] First limiting block groove 14: It is opened on both sides of the inner wall of the oil storage tank installation groove 13, providing sliding space and guidance for the limiting block 15, and also providing guidance and constraint for the movement of the slide rod 6 and the push block 8, ensuring that the limiting block 15 will not deviate or get stuck during the sliding process, and ensuring the normal operation of the limiting component.
[0048] Limiting block 15: It slides within the first limiting block groove 14 and the second limiting block groove 16. One end is fixedly connected to the slide rod 6 and the push block 8, and the other end can be inserted into or detached from the second limiting block groove 16. Through the drive of the slide rod 6 and the push block 8, it can engage or disengage with the second limiting block groove 16, thereby controlling the limiting state of the oil storage tank 4. It is a key component for the limiting assembly to realize the limiting function.
[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
