Description

Technical Field

[0001] This utility model belongs to the technical field of butter containers, and specifically relates to a butter container. Background Technology

[0002] Electric grease cans are commonly used tools in the lubrication and maintenance of construction machinery, mainly for the efficient and convenient addition of grease.

[0003] Most commercially available butter containers consist of a container body with a storage chamber inside. The container body also houses a pump assembly and a drive motor. The drive motor moves the pump assembly to discharge the butter from the storage chamber. For example, Chinese Utility Model Patent Application CN 202321548053.8 discloses an electric butter container, which includes a container body for storing butter. The container body has a pump assembly mounted on it. The container body includes a base and an upper shell detachably mounted on the base. The pump assembly is detachably mounted on the base, and the upper shell has a receiving chamber inside. The pump assembly includes a pump body with a motor, a manifold, and a plunger. The manifold has an inner cavity in the center, and the outlet of the inner cavity has a connector. The bottom of the receiving chamber has an inlet connecting the inner cavity and the receiving chamber. The plunger is located in the inner cavity, and a transmission structure is provided between the motor and the plunger. The motor drives the plunger through the transmission structure. The pump body is equipped with a motor control circuit board, which can control the motor to start and stop. The transmission structure includes a reduction gear set and an eccentric shaft. The eccentric shaft is equipped with an eccentric part for driving the piston movement, and a stirring blade is provided at the output end of the eccentric shaft. The eccentric shaft drives the stirring blade to rotate relative to each other in the receiving cavity. The eccentric shaft is equipped with at least two identical eccentric parts, and the eccentric parts are inclined. The pump body is slidably equipped with connecting seats adapted to each eccentric part, and a set of pistons is provided on both sides of the connecting seat. The eccentric part drives the connecting seat to slide in the pump body and drives the pistons on both sides of the connecting seat to move.

[0004] As shown in the attached diagram of the instruction manual, the plungers on both sides of the connecting seat in the above structure are vertically distributed. During the rotation of the eccentric shaft, the two eccentric parts drive one inner cavity on each side of the connecting seat to discharge grease. During this process, the plunger on each side of the eccentric shaft will be subject to greater resistance, which will cause the eccentric shaft to be subjected to excessive force and affect the service life of the grease container. Summary of the Invention

[0005] In order to overcome the defects in the prior art, the purpose of this utility model is to provide a butter container with a long service life.

[0006] The purpose of this utility model is achieved as follows:

[0013] The present invention is further configured such that the centers of the two eccentric blocks are symmetrically arranged along the center of the transmission shaft, thereby preventing the simultaneous discharge of grease from the first inner cavity and the second inner cavity on one side of the mounting cavity.

[0014] The present invention is further configured such that: a first inner cavity and a second inner cavity are provided on both the left and right sides of the mounting cavity, and the first inner cavity and the second inner cavity in the same group are respectively provided on the front and rear sides of the transmission shaft axis.

[0017] The present invention is further configured such that: at least three guide rods are provided on the lid of the bucket, and the guide rods are arranged around the center circumference of the storage cavity.

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. In this utility model, the first inner cavity and the second inner cavity are located on the same side of the mounting cavity, and the first inner cavity and the second inner cavity are arranged sequentially in the horizontal direction. During the rotation of the transmission shaft, due to the eccentric block driving the first plunger rod and the second plunger rod to move alternately, the first inner cavity and the second inner cavity on both sides of the mounting cavity will not start discharging grease at the same time. When one of the first inner cavity and the second inner cavity is discharging grease, the other will start discharging grease, so that the discharge of grease will not be interrupted, which is conducive to the continuous discharge of grease from the grease container and convenient for users. In addition, this process can shorten the time when the transmission shaft is simultaneously subjected to the resistance of the first plunger rod and the second plunger rod, which is conducive to reducing the force on the transmission shaft during use, reducing the wear and deformation of the transmission shaft during use, and thus helping to extend the service life of the grease container.

[0020] 2. The first plunger rod and the second plunger rod arranged sequentially along the axial direction of the drive shaft in this utility model facilitate the distribution of force on the drive shaft, preventing damage or severe wear to the drive shaft due to stress concentration, and thus extending the service life of the grease container. Furthermore, since the center of the first plunger rod is located obliquely above the center of the second plunger rod, this structure helps to reduce the distance between the first and second plunger rods in both the lateral and longitudinal directions, thereby reducing the volume of the outer casing, facilitating the installation of the grease container, and reducing the cost of the grease container. The vertically arranged connecting hole facilitates the production and processing of the outer casing, while the oil guide pipe facilitates the centralized oil discharge from the grease container, making it convenient for users.

[0021] 3. The connector and groove in this utility model facilitate the simultaneous synchronous movement of the two first plunger rods or the two second plunger rods driven by the eccentric blocks. Its simple structure facilitates manufacturing and processing. This structure also facilitates the reciprocating motion of the first and second plunger rods driven by the eccentric blocks, enabling the drive motor to drive the transmission shaft at high speed. The eccentric arrangement of the two eccentric blocks allows the first and second plunger rods on the same side of the mounting cavity to move alternately, preventing simultaneous oil discharge from the first and second inner cavities on the same side of the mounting cavity. This reduces the stress on the transmission shaft during use, minimizing wear and deformation, thus extending the service life of the grease container. Because the centers of the two eccentric blocks are symmetrically arranged along the center of the transmission shaft, it facilitates the cross-discharge of grease from the first and second inner cavities on both sides of the mounting cavity. Furthermore, the horizontal distance L between the axes of the first and second inner cavities promotes uniform circumferential stress on the transmission shaft, reducing localized wear and deformation during use, further extending the service life of the grease container.

[0022] 4. In this utility model, a first inner cavity and a second inner cavity are provided on both the left and right sides of the mounting cavity. The first inner cavity and the second inner cavity in the same group are respectively located on the front and rear sides of the transmission shaft axis. During the rotation of the transmission shaft, the eccentric block will sequentially drive one of the two first inner cavities and one of the two second inner cavities to discharge grease. This structure facilitates the dispersion of force on the transmission shaft, reduces wear and deformation of the transmission shaft, and thus helps to extend the service life of the grease container. This structure also facilitates the uniform oil discharge from the grease container, making it convenient for users. The two first inner cavities and two second inner cavities arranged coaxially not only facilitate the stable sliding of the first plunger rod, the second plunger rod and the connecting parts, but also reduce the torque generated on the connecting parts, avoiding excessive friction between the first plunger rod and the second plunger rod, which helps to extend the service life of the grease container and facilitates high-speed oil discharge from the grease container.

[0023] 5. The design of the pressure plate and elastic element in this utility model facilitates pushing the grease to the bottom of the storage cavity, allowing the grease to be discharged through the pump assembly. The guide rods facilitate the stable sliding of the pressure plate, preventing it from tilting during use and affecting its driving force on the grease, thus making it convenient for the user. At least three guide rods arranged along the central circumference of the storage cavity further facilitate the stable sliding of the pressure plate, preventing it from tilting during use and allowing it to push the grease to the bottom of the storage cavity, facilitating the full discharge of the grease.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0040] See Figures 1 to 11As shown, a butter container includes a container body 1, with a storage cavity 11 for storing butter. A pump assembly and a drive motor 3 are mounted on the container body 1. The pump assembly includes a housing 5, with a plunger rod mounted on the housing 5. The output end of the drive motor 3 is connected to a drive shaft 41, with an eccentric block 411 mounted on the drive shaft 41 for driving the plunger rod. A mounting cavity 511 is provided in the housing 5, with both the eccentric block 411 and the drive shaft 41 housed within it. A first inner cavity 53 and a second inner cavity 54 are provided on both sides of the mounting cavity 511. The plunger rod includes a first inner cavity 53 that is slidably disposed in the first inner cavity 53 and the second inner cavity 54 respectively. The plunger rod 6 and the second plunger rod 61, the oil inlet end 531 of the first inner cavity 53 and the second inner cavity 54 are connected to the storage cavity 11, and the oil outlet end 532 of the first inner cavity 53 and the second inner cavity 54 are both connected to the oil outlet 8 and discharge grease outward; the horizontal distance between the axes of the first inner cavity 53 and the second inner cavity 54 on the same side of the mounting cavity 511 is L. During the rotation of the eccentric block 411 driven by the drive motor 3, the eccentric block 411 drives the first plunger rod 6 and the second plunger rod 61 to move alternately, and causes the grease in the first inner cavity 53 and the second inner cavity 54 on both sides of the mounting cavity 511 to start to be discharged in sequence, so that oil is continuously discharged from the oil outlet (8).

[0041] In the above structure, since the first inner cavity 53 and the second inner cavity 54 are arranged horizontally in sequence, during the rotation of the drive shaft 41, the eccentric block 411 drives the first plunger rod 6 and the second plunger rod 61 to move alternately. Therefore, the first inner cavity 53 and the second inner cavity 54 on both sides of the mounting cavity 511 will not start discharging grease simultaneously. While one inner cavity 53 or the other inner cavity 54 is discharging grease, the other will begin discharging grease, ensuring uninterrupted grease discharge. This facilitates continuous grease discharge from the grease container, making it convenient for the user. Furthermore, this process shortens the time during which the drive shaft 41 is simultaneously subjected to the resistance of the first plunger rod 6 and the second plunger rod 61, reducing the stress on the drive shaft 61 during use, decreasing wear and deformation, and thus extending the service life of the grease container.

[0042] In this embodiment, the drive motor 3 is connected to a transmission gear set 4. The drive motor 3 drives the transmission shaft 41 to rotate through the transmission gear set 4. The transmission shaft 41 is provided with an agitator 42. The transmission shaft 41 drives the agitator 42 to rotate and make the butter flow, so as to facilitate the butter to enter the oil inlet 531 of the first inner cavity 53 and the second inner cavity 54. The outer shell 5 includes a detachably connected upper shell 52 and a lower shell 51. The mounting cavity 511 is disposed between the upper shell 52 and the lower shell 51.

[0043] In this invention, the first plunger rod 6 and the second plunger rod 61 are arranged sequentially along the axial direction of the transmission shaft 41, with the center of the first plunger rod 6 positioned obliquely above the center of the second plunger rod 61. Two eccentric blocks 411 are arranged sequentially along the axial direction of the transmission shaft 41. The two eccentric blocks 411 can drive the first plunger rod 6 and the second plunger rod 61 to move alternately, causing the grease in the first inner cavity 53 and the second inner cavity 54 to be discharged sequentially. The first plunger rod 6 and the second plunger rod 61 arranged sequentially along the axial direction of the transmission shaft 41 facilitate the dispersion of the force on the transmission shaft 41, preventing the transmission shaft 41 from being damaged or severely worn due to stress concentration, which helps to extend the service life of the grease container. Furthermore, since the center of the first plunger rod 6 is positioned obliquely above the center of the second plunger rod 61, this structure helps to reduce the distance between the first plunger rod 6 and the second plunger rod 61 in both the lateral and longitudinal directions, which helps to reduce the volume of the outer shell 5, facilitates the installation of the grease container, and reduces the cost of the grease container.

[0044] The projections of the first inner cavity 53 and the second inner cavity 54 in the horizontal direction can be set at intervals, and the projections of the first inner cavity 53 and the second inner cavity 54 in the horizontal direction can also intersect. Those skilled in the art can adjust them freely according to actual needs.

[0045] Preferably, the outer shell 5 is provided with a connection hole 55. The connection hole 55 is vertically arranged and connects the first inner cavity 53 and the second inner cavity 54 on the same side of the mounting cavity 511. The oil outlet 8 is connected to the connection hole 55, and an oil guide pipe 9 is connected between the connection holes 55 on both sides of the outer shell 5. The vertically arranged connection hole 55 facilitates the production and processing of the outer shell 5, and the oil guide pipe 9 facilitates the centralized oil discharge of the grease container, making it convenient for users.

[0046] In this invention, four eccentric blocks 411 can be provided on the drive shaft 41, with one eccentric block 411 corresponding to each of the first plunger rod 6 and the second plunger rod 61. However, this would result in a longer drive shaft 41, which would be prone to bending and wear during production and use. In this embodiment, the eccentric blocks 411 are provided with connecting members 7, and the connecting members 7 are provided with grooves 71. The eccentric blocks 411 move in the grooves 71 and can drive the connecting members 7 to reciprocate. The connecting members 7 connect the two first plunger rods 6 or the two second plunger rods 61. The two plunger rods 61 are connected; during the rotation of the eccentric block 411 driven by the drive motor 3, the connecting piece 7 drives the two first plunger rods 6 or the two second plunger rods 61 to move synchronously. The setting of the connecting piece 7 and the slot 71 makes it easy for the eccentric block 411 to drive the two first plunger rods 6 or the two second plunger rods 61 to move synchronously at the same time. Its structure is simple and convenient for production and processing. Moreover, this structure makes it easy for the eccentric block 411 to drive the first plunger rods 6 and the second plunger rods 61 to reciprocate, and makes it easy for the drive motor 3 to drive the transmission shaft 41 to rotate at high speed.

[0047] The eccentric block 411 can abut against the connector 7 and drive the connector 7 to move synchronously with the plunger rod. The eccentric block 411 can also abut against the plunger rod and drive the connector 7 to move synchronously with the plunger rod.

[0048] In this embodiment, a guide groove 72 is provided on the lower side of the groove 71, the drive shaft 41 passes through the guide groove 72, and the side wall of the groove 71 is provided with a mounting hole 73 for installing the first plunger rod 6 or the second plunger rod 61.

[0049] The two eccentric blocks 411 are eccentrically positioned, and the drive shaft 41 drives the two eccentric blocks 411 to rotate. The two eccentric blocks 411 drive the first plunger rod 6 and the second plunger rod 61 on the same side of the mounting cavity 511 to move alternately, so that the grease in the first inner cavity 53 and the second inner cavity 54 on the same side of the mounting cavity 511 is discharged in sequence. The eccentric positioning of the two eccentric blocks 411 facilitates the alternate movement of the first plunger rod 6 and the second plunger rod 61 on the same side of the mounting cavity 511, and avoids the simultaneous discharge of grease from the first inner cavity 53 and the second inner cavity 54 on the same side of the mounting cavity 511. This helps to reduce the force on the drive shaft 41 during use, reduce the wear and deformation of the drive shaft 41 during use, and thus help to extend the service life of the grease container.

[0050] In this embodiment, the centers of the two eccentric blocks 411 are symmetrically arranged along the center of the drive shaft 41, which is beneficial for the cross discharge of grease from the first inner cavity 53 and the second inner cavity 54 on both sides of the mounting cavity 511. Since the horizontal distance between the axes of the first inner cavity 53 and the second inner cavity 54 is L, it is beneficial to reduce the time when the first inner cavity 53 and the second inner cavity 54 discharge grease at the same time, which is beneficial to the uniform force on the circumference of the drive shaft 41, thereby reducing the local wear and deformation of the drive shaft 41 during use, and thus helping to extend the service life of the grease container.

[0051] The mounting cavity 511 has a set of first inner cavities 53 and second inner cavities 54 on both the left and right sides. The first inner cavities 53 and second inner cavities 54 in the same set are respectively located on the front and rear sides of the axis of the transmission shaft 41. During the rotation of the transmission shaft 41, the eccentric block 411 will drive one of the two first inner cavities 53 and the two second inner cavities 54 in sequence to discharge grease. This structure facilitates the distribution of force on the transmission shaft 41, reduces the wear and deformation of the transmission shaft 41, and thus helps to extend the service life of the grease container. This structure also facilitates the uniform discharge of grease from the grease container and makes it convenient for users to use.

[0052] In this embodiment, two first inner cavities 53 and two second inner cavities 54 are respectively arranged on the front and rear sides of the transmission shaft 41. During the rotation of the transmission shaft 41, the two eccentric blocks 411 drive the first plunger rod 6 and the second plunger rod 61 to move in a continuous reciprocating motion. First, one first inner cavity 53 starts to dispense oil, and then one second inner cavity 54 starts to dispense oil. After that, the first inner cavity 53 stops dispensing oil, and then another first inner cavity 53 dispenses oil, and then another second inner cavity 54 stops dispensing oil. After that, another second inner cavity 54 dispenses oil, and then another first inner cavity 53 stops dispensing oil, and then another second inner cavity 54 stops dispensing oil. At this time, the transmission shaft 41 rotates one revolution, and the above oil dispensing steps begin to cycle. During this process, it is ensured that there is always one first inner cavity 53 or a second inner cavity 54 dispensing oil during the rotation of the transmission shaft 41, so that the oil dispensing process of the grease can is not interrupted during use.

[0053] In this embodiment, the first inner cavities 53 on both sides of the mounting cavity 511 are coaxially arranged, and the second inner cavities 54 on both sides of the mounting cavity 511 are coaxially arranged. The two first inner cavities 53 and two second inner cavities 54 coaxially arranged not only facilitate the stable sliding of the first plunger rod 6, the second plunger rod 61 and the connecting piece 7, but also reduce the torque generated on the connecting piece 7, avoid the excessive friction between the first plunger rod 6 and the second plunger rod 61 caused by this, which helps to extend the service life of the grease container and facilitates high-speed oil output from the grease container.

[0054] The upper end of the barrel 1 is detachably equipped with a barrel lid 2. The oil inlet end 531 of the first inner cavity 53 and the second inner cavity 54 is connected to the bottom of the storage cavity 11. The storage cavity 11 is equipped with a pressure plate 24 and an elastic element 23. The elastic element 23 abuts against the barrel lid 2 and can drive the pressure plate 24 to move towards the bottom of the storage cavity 11, so that the grease in the storage cavity 11 flows towards the bottom of the storage cavity 11. The barrel lid 2 is equipped with a guide rod 22. The pressure plate 24 is slidably connected to the guide rod 22. The setting of the pressure plate 24 and the elastic element 23 facilitates pushing the grease to the bottom of the storage cavity 11, so that the grease can be discharged through the pump assembly. The setting of the guide rod 22 facilitates the stable sliding of the pressure plate 24, and avoids the pressure plate 24 tilting during use, which affects the driving of the pressure plate 24 on the grease. It is convenient for users to use. In this embodiment, the barrel lid 2 is equipped with a lid bead 21. The user can pick up the barrel lid 2 through the lid bead 21.

[0055] Preferably, a sealing ring is provided on the outer periphery of the pressure plate 24. The sealing ring can make the outer periphery of the pressure plate 24 fit tightly with the side wall of the storage cavity 11, which can reduce or even prevent grease from flowing out from the gap between the pressure plate 24 and the side wall of the storage cavity 11.

[0056] Preferably, the lid 2 is provided with at least three guide rods 22, which are arranged around the center circumference of the storage cavity 11. This structure is conducive to the stable movement of the pressure plate 24, avoids the pressure plate 24 tilting during use, and helps the pressure plate 24 push the grease to the bottom of the storage cavity 11, facilitating the full discharge of the grease. In this embodiment, the lid 2 is provided with three threaded holes 25, and the guide rods 22 are threadedly connected to the three threaded holes 25 respectively. The pressure plate 24 is provided with guide holes 242 that are slidably connected to the guide rods 22. The guide rods 22 are provided with limit ends 221, which are located at the lower end of the limit block and prevent the pressure plate 24 from separating from the guide rods 22.

[0057] In this utility model, the bottom of the barrel 1 is provided with a support wheel, and the side of the barrel 1 is provided with a handle 13 and a fixing buckle 14. The user can lift the grease barrel by the handle 13, and the fixing buckle 14 can drive the barrel lid 2 to be fixed on the upper end of the barrel 1. In this embodiment, the barrel 1 is provided with a controller 12 for controlling the drive motor 3.

[0058] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
