Description

Technical Field

[0001] This utility model relates to a plug-in self-filling electric grease filling component adapted to a standard grease container. Background Technology

[0002] In the field of construction machinery, the working parts of construction machinery are in direct contact with materials. If a centralized lubrication system is installed, the lubrication pipelines and distributors of the centralized lubrication system are often easily damaged by the impact of materials, which affects the overall operation of the lubrication system. Therefore, the working parts of construction machinery (actuators, such as the lubrication of the connecting rod corresponding to the bucket of an excavator) are generally lubricated manually. For ease of operation, electric grease guns are often used.

[0003] However, the capacity of electric handheld grease guns is very limited. For medium, large, and super-large construction machinery, one grease gun is far from enough, and grease needs to be replenished into the grease reservoir multiple times. The existing method generally uses a piston structure, similar to the structure of a medical syringe. The hand-held lever pulls the piston to draw grease from the standard grease container. Since grease is a semi-fluid, its flowability is extremely poor. This process is very laborious and time-consuming. Moreover, due to the harsh on-site environment and improper operation by personnel, impurities often fall into the grease container during manual grease replenishment, contaminating the grease and affecting its lubricating performance. Utility Model Content

[0004] The purpose of this invention is to provide a plug-in self-replenishing electric grease filling component that is compatible with standard grease containers. It can be directly adapted to standard grease containers. The central grease suction tube of the plug-in grease suction device is inserted into the bottom of the grease container. Then, the electric grease gun is rotated in the forward direction to drive the plug-in grease suction device to draw grease from the grease container and replenish it into the grease reservoir of the electric grease gun. This achieves a rapid self-replenishing effect, significantly improves grease filling efficiency, and makes the grease filling process easier and less labor-intensive. In addition, the plug-in grease suction device has a protective effect on the grease in the grease container, preventing dust, debris, rainwater, etc. from falling into the grease container and contaminating the grease.

[0005] The technical solution of this utility model for a self-filling electric grease filling assembly for standard grease containers is as follows: The self-filling electric grease filling assembly for standard grease containers includes:

[0006] A grease extraction device for inserting into a standard grease container and extracting grease includes a positioning cap, a central grease extraction tube, a grease extraction auger, and a worm gear mechanism. The positioning cap is fixed to the opening of the standard grease container. The central grease extraction tube is fixed at the center of the positioning cap, with a cap at the top and its lower end inserted into the bottom of the container. The lower end of the central grease extraction tube has a grease inlet, and one side of its upper part has a grease outlet, to which a first quick-connect fitting is connected. A liposuction auger is rotatably mounted inside the central liposuction tube, extending from one end of the central liposuction tube to the other end. The liposuction auger includes a central rotating shaft and spiral conveying blades spirally arranged around it. The outer diameter of the spiral conveying blades is the same as the inner diameter of the central liposuction tube. The upper end of the central rotating shaft passes through the cap and extends outward. The upper end of the central rotating shaft is rotatably sealed with the cap. The worm gear mechanism includes a worm and a worm gear that are engaged in transmission. The worm gear is rotatably mounted on the upper end of the central rotating shaft. One end of the worm gear has a first transmission quick-connect connector.

[0007] An electric grease gun includes a grease reservoir, a drive motor, a ratchet mechanism, and a grease dispensing plunger assembly. The grease reservoir has a grease inlet, and a second quick-connect fitting is connected to the inlet via a grease hose. The drive motor includes a motor output shaft, and the outer end of the motor output shaft is equipped with a second quick-connect fitting. The first and second quick-connect fittings can be quickly inserted and engaged to achieve mutual transmission. The ratchet mechanism is installed in the middle of the motor output shaft and includes an inner wheel, a pawl, and an outer wheel. The inner wheel is fixedly connected to the motor output shaft, and the pawl is rotatably mounted on the inner wheel. The outer wheel has an eccentrically positioned inner circular hole, and the inner circumference of the inner circular hole is... It has ratchet teeth and a pawl that engage with the ratchet teeth in a one-way transmission. When the motor output shaft reverses, the inner wheel drives the outer wheel to rotate through the pawl. The inner and outer wheels form an eccentric wheel mechanism. The grease discharge plunger pair is driven by the eccentric wheel mechanism to pressurize and pump the grease in the grease reservoir out. When the motor output shaft rotates forward, the first quick-connect fitting and the second quick-connect fitting are inserted and engaged. The pawl and ratchet teeth disengage, and the second quick-connect fitting of the motor output shaft can be inserted into the first quick-connect fitting of the worm gear to drive the worm gear to rotate. The grease suction auger rotates accordingly, transporting the grease along the central grease suction tube to the grease reservoir.

[0008] The beneficial effects of this solution are as follows: During normal operation, the electric grease gun reverses the motor via a switch, causing the motor output shaft to reverse, which in turn drives the inner wheel to reverse. The pawl on the inner wheel meshes with the ratchet on the outer wheel, driving the outer wheel to reverse as well. The outer wheel, as part of the eccentric wheel mechanism, can drive the grease plunger to extract grease from the grease reservoir and pump it out under high pressure to lubricate the lubrication points. When the grease reservoir needs replenishment, open the lid of the standard grease container and insert the grease extraction device into the container from the opening, ensuring the positioning cover is fixed in place at the opening. This allows for the positioning of the central grease extraction tube, which is now located at the center of the grease container, with its lower end inserted into the grease until it reaches the bottom. Then, connect the second quick-connect fitting of the electric grease gun to the first quick-connect fitting of the grease extraction device. Next, connect the second quick-connect coupling of the electric grease gun to the first quick-connect coupling of the suction tube device. Then, control the motor to rotate forward by switching on the electric grease gun. At this time, since the ratchet and pawl are unidirectionally meshed, they disengage, meaning the inner wheel cannot transmit power to the outer wheel. The inner wheel rotates freely with the motor output shaft. However, the motor output shaft, through the transmission between the second and first quick-connect couplings, can drive the worm gear to rotate, which in turn drives the turbine and the central shaft to rotate, and the spiral conveying blades to rotate. Using the conveying mechanism formed by the spiral conveying blades and the central suction tube, the grease in the grease tank is conveyed upward. The grease passes through the grease inlet and outlet of the central suction tube, the first quick-connect coupling, the second quick-connect coupling, and the grease replenishment hose in sequence into the grease reservoir of the electric grease gun for rapid grease replenishment. As can be seen from the above working process, this application can be directly adapted to a standard grease container. By cooperating with the positioning cover of the grease extraction device and the container opening, the central grease extraction tube is positioned, and a seal is formed for the container opening. Then, the electric grease gun is rotated forward to drive the grease extraction device to draw grease from the grease container and replenish it into the grease reservoir of the electric grease gun, achieving a rapid self-greasing effect. The grease replenishment efficiency is significantly improved, and the grease replenishment process is easier and less labor-intensive. In addition, the grease extraction device has a protective effect on the grease in the grease container, preventing dust, debris, rainwater, etc. from falling into the grease container and contaminating the grease.

[0009] Furthermore, it includes a follow-up float for conforming to and moving with the liquid surface. The follow-up float includes a sliding sleeve slidably mounted outside the central grease suction tube and a sealing disc fixed to the sliding sleeve. The outer periphery of the sealing disc is used for sliding and sealing with the wall of the standard grease container. The follow-up float serves two purposes: firstly, it can centrally position the central grease suction tube, forming a two-point positioning structure with the positioning lid, making the central grease suction tube less prone to deflection and ensuring more thorough grease removal; secondly, the follow-up float can also descend with the liquid surface to scrape off residual grease from the container wall.

[0010] Furthermore, there are multiple grease inlets, which are evenly distributed circumferentially along the lower side of the central grease extraction tube. This circumferentially distributed arrangement of the grease inlets ensures that even if the central grease extraction tube is relatively close to the bottom of the container, it does not affect the speed at which the grease enters through the grease inlets.

[0011] Furthermore, the central rotating shaft is provided with at least two support bearings, each support bearing including an inner ring, an outer ring, and a roller assembly. The inner ring is fitted onto and fixed on the central rotating shaft, and the outer ring is fixed to the inner wall of the central liposuction tube by at least three evenly distributed support rods.

[0012] Furthermore, there are three support bearings, which are evenly distributed along the length of the central axis. The spiral conveying blade is separated from the middle support bearing by a region to avoid interference between the spiral conveying blade and the support bearing.

[0013] Furthermore, the spiral conveying blade includes an elastic rubber portion vulcanized at its outer edge. This elastic rubber portion can slide and seal against the inner wall of the central grease extraction tube to improve the sealing performance of the conveyed grease. The elastic rubber portion allows the spiral conveying blade and the central grease extraction tube to form a sealed conveying structure, which can increase the conveying pressure of the grease and make it easier for the grease to overcome the resistance of the spring piston inside the grease storage cylinder and enter the grease storage cylinder.

[0014] Furthermore, the structure of the first transmission quick connector includes a cross-shaped boss and a positioning frustum spaced apart from the cross-shaped boss, and the structure of the second transmission quick connector includes a matching cross-shaped groove.

[0015] Furthermore, the drive motor is a speed-regulating motor, and the forward and reverse rotation speeds of the drive motor can be adjusted separately via a switch to control the oil replenishment speed and oil output speed.

[0016] Furthermore, a fixed bracket is fixed to the outside of the positioning cover, and the two ends of the worm gear are respectively rotatably assembled on the fixed bracket through bearings.

[0017] Furthermore, the electric grease gun includes a removable rechargeable battery.

[0018] Furthermore, the grease reservoir is equipped with a spring and a piston, and the grease filling port is located at the end away from the spring.

[0019] Furthermore, it includes a carrying case with a placement space inside that is adapted to the shape of the electric liposuction gun and the canister liposuction device.

[0020] Furthermore, the outer circumferential surface of the outer wheel is provided with an annular groove, and one end of the plunger of the grease outlet plunger assembly slides in the annular groove through a hook structure. Attached Figure Description

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0033] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0034] Specific embodiments of the self-filling electric grease dispenser assembly adapted to standard grease containers of this utility model are as follows: Figure 1-8 As shown, the plug-in self-filling electric grease dispenser assembly for standard grease containers mainly includes a plug-in grease extraction device 2, an electric grease gun 3, and a carrying case. The carrying case has placement positions that are compatible with the shape of the electric grease gun 3 and the plug-in grease extraction device 2.

[0035] like Figure 1As shown, the grease extraction device 2 is used to insert into a standard grease container and extract grease from it. It includes a positioning cover 21, a central grease extraction tube 23, a grease extraction auger 24, and a worm gear mechanism 25. The positioning cover 21 is used to cover the opening of the standard grease container and is fixed relative to the opening. The central grease extraction tube 23 is fixed at the center of the positioning cover 21. The top of the central grease extraction tube 23 has a cap 231, and the lower end of the central grease extraction tube 23 is used to insert into the bottom of the container. The lower end of the central grease extraction tube 23 has a grease inlet 232, and the upper side of the central grease extraction tube 23 has a grease outlet 233. A first quick-connect fitting 234 is connected to the grease outlet 233. The inner rotating assembly is equipped with a liposuction auger 24, which extends from one end of the central liposuction tube 23 to the other end. The liposuction auger 24 includes a central rotating shaft 241 and spiral conveying blades 242 spirally arranged thereon. The outer diameter of the spiral conveying blades 242 is the same as the inner diameter of the central liposuction tube 23. The upper end of the central rotating shaft 241 extends outward after passing through the cover 231. The upper end of the central rotating shaft 241 is rotatably sealed with the cover 231. The worm gear 252 mechanism includes a worm 251 and a worm 252 that are in a transmission engagement. The worm 251 is rotatably mounted on the upper end of the central rotating shaft 241. One end of the worm 252 has a first transmission quick-connect connector 2521. It also includes a follow-up float 22 for conforming to and moving with the liquid surface. The follow-up float 22 includes a sliding sleeve 221 slidably mounted on the outside of the central grease extraction tube 23 and a sealing disc 222 fixed on the sliding sleeve 221. The outer periphery of the sealing disc 222 is used for sliding and sealing with the wall of the standard grease container. The follow-up float 22 can, on the one hand, provide intermediate positioning for the central grease extraction tube 23, forming a two-point positioning structure with the positioning lid, making the central grease extraction tube 23 less prone to deflection and ensuring more thorough grease extraction; on the other hand, the follow-up float 22 can also descend with the liquid surface to scrape off residual grease from the container wall. There are multiple grease inlets 232, which are evenly distributed circumferentially along the lower side of the central grease extraction tube 23. The circumferentially distributed arrangement of the grease inlets 232 ensures that even if the central grease extraction tube 23 is relatively close to the bottom of the container, it does not affect the speed at which the grease enters from the grease inlets 232. At least two support bearings 27 are provided on the central rotating shaft 241. Each support bearing 27 includes an inner ring 271, an outer ring 272, and a roller assembly 273. The inner ring 271 is fitted onto and fixed to the central rotating shaft 241, and the outer ring 272 is fixed to the inner wall of the central grease extraction tube 23 by at least three evenly distributed support rods 274. In this embodiment, there are three support bearings 27, evenly distributed along the length of the central rotating shaft 241. The spiral conveying blade 242 is interrupted at the position corresponding to the middle support bearing 27 to avoid interference between the spiral conveying blade 242 and the support bearing 27. In other embodiments, the spiral conveying blade 242 includes an elastic rubber portion vulcanized at its outer edge. This elastic rubber portion can slide and seal against the inner wall of the central grease extraction tube 23 to improve the sealing performance of the conveyed grease.The elastic rubber section allows the spiral conveying blades 242 and the central grease extraction tube 23 to form a sealed conveying structure, which increases the conveying pressure of the grease and makes it easier for the grease to overcome the resistance of the spring 312 and piston 313 inside the grease storage cylinder 31 and enter the grease storage cylinder 31. A fixed bracket is fixed to the outside of the positioning cover 21, and the two ends of the worm gear 252 are respectively rotatably mounted on the fixed bracket through bearings.

[0036] like Figure 5-8 As shown, the electric grease gun 3 includes a grease reservoir 31, a drive motor 32, a ratchet mechanism 33, and a grease dispensing plunger assembly 34. The grease reservoir 31 has a grease filling port 311, and a second quick-connect fitting is connected to the grease filling port 311 via a grease filling hose. The drive motor 32 includes a motor output shaft 321, and a second transmission quick-connect fitting 3211 is provided at the outer end of the motor output shaft 321. The first and second transmission quick-connect fittings 3211 can be quickly inserted and engaged to achieve mutual transmission. The ratchet mechanism 33 is installed in the middle of the motor output shaft 321. The ratchet mechanism 33 includes an inner wheel 331, a pawl 332, and an outer wheel 333. The inner wheel 331 is fixedly connected to the motor output shaft 321, and the pawl 332 is rotatably mounted on the inner wheel 331. The outer wheel 333 has an eccentrically set inner circular hole, and the inner circumferential surface of the inner circular hole is provided with... The ratchet 3331 and pawl 332 are engaged in a one-way transmission with the ratchet 3331. When the motor output shaft 321 reverses, the inner wheel 331 drives the outer wheel 333 to rotate through the pawl 332. The inner wheel 331 and the outer wheel 333 form an eccentric wheel mechanism. The grease discharge plunger pair 34 is driven by the eccentric wheel mechanism to pressurize and pump the grease in the grease reservoir 31 out. When the motor output shaft 321 rotates forward, the first quick-connect tube connector 234 is inserted into the second quick-connect tube connector, and the pawl 332 disengages from the ratchet 3331. The second transmission quick-connect tube connector 3211 of the motor output shaft 321 can be inserted into the first transmission quick-connect tube connector 2521 of the worm 252 to drive the worm 252 to rotate. The grease suction auger 24 rotates accordingly, transporting the grease along the central grease suction tube 23 to the grease reservoir 31. The drive motor 32 is a speed-regulating motor, and its forward and reverse rotation speeds can be adjusted via a switch to control the grease filling and dispensing speeds. The first transmission quick-connect connector 2521 includes a cross-shaped boss 25211 and a positioning frustum 25212 spaced around the cross-shaped boss 25211. The second transmission quick-connect head includes a matching cross-shaped groove 32111. The drive motor 32 is a speed-regulating motor, and its forward and reverse rotation speeds can be adjusted via a switch to control the grease filling and dispensing speeds. The electric grease gun 3 includes a removable rechargeable battery 35. The grease reservoir 31 contains a spring 312 and a piston 313, and the grease filling port 311 is located at the end away from the spring 312. The outer circumferential surface of the outer wheel 333 has an annular groove 3332, and one end of the plunger of the grease dispensing plunger pair 34 slides within the annular groove 3332 via a hook structure.

[0037] During normal operation, the electric grease gun 3 reverses the motor via a switch, causing the motor output shaft 321 to reverse, which in turn drives the inner wheel 331 to reverse. The pawl 332 on the inner wheel 331 meshes with the ratchet 3331 on the outer wheel 333, driving the outer wheel 333 to reverse. The outer wheel 333, as part of the eccentric wheel mechanism, can drive the grease plunger assembly 34 to draw out the grease from the grease reservoir 31 and pump it out under high pressure to lubricate the lubrication points. When the grease reservoir 31 needs to be replenished, Open the lid of the standard grease container and insert the grease extraction device 2 into the container from the opening. Ensure that the positioning cover 21 is fixedly placed at the opening, thus positioning the central grease extraction tube 23. At this point, the central grease extraction tube 23 is located at the center of the grease container, and its lower end is inserted into the grease until it reaches the bottom of the container. Then, connect the second quick-connect fitting of the electric grease gun 3 to the first quick-connect fitting 234 of the grease extraction device 2, and connect the second quick-connect fitting 3 of the electric grease gun 3. 211 connects to the first transmission quick-connect joint 2521 of the suction device 2, and then controls the motor to rotate forward via the switch of the electric grease gun 3. At this time, since the ratchet 3331 and the pawl 332 have a one-way meshing structure, they disengage, meaning the inner wheel 331 cannot transmit power to the outer wheel 333. The inner wheel 331 rotates freely with the motor output shaft 321, but the motor output shaft 321 can still rotate freely through the transmission between the second transmission quick-connect joint 3211 and the first transmission quick-connect joint 2521. The worm gear 252 rotates, which in turn rotates the turbine 251 and the central shaft 241, causing the spiral conveying blades 242 to rotate. The conveying mechanism formed by the spiral conveying blades 242 and the central grease extraction tube 23 transports the grease in the grease tank upwards. The grease passes through the grease inlet 232, grease outlet 233, first quick-connect tube connector 234, second quick-connect tube connector, and grease replenishment hose of the central grease extraction tube 23 in sequence and enters the grease reservoir 31 of the electric grease gun 3 for rapid grease replenishment. As can be seen from the above working process, this application can be directly adapted to a standard grease container. By cooperating the positioning cover 21 of the grease extraction device 2 with the container opening, the central grease extraction tube 23 is positioned, and a seal is formed for the container opening. Then, the electric grease gun 3 is rotated forward to drive the grease extraction device 2 to draw grease from the grease container to replenish the grease reservoir 31 of the electric grease gun 3, achieving a rapid self-grease replenishment effect. The grease replenishment efficiency is significantly improved, and the grease replenishment process is easier and less labor-intensive. In addition, the grease extraction device 2 has a protective effect on the grease in the grease container, preventing dust, debris, rainwater, etc. from falling into the grease container and contaminating the grease.

Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
