Description

Technical Field

[0001] The utility model relates to an oil filling device, in particular to a butter filling device. Background Art

[0002] The grease filling device is a device for filling grease for automobiles and other equipment. The existing portable grease filling gun includes a gun body and a gun barrel rotatably connected to the gun body. The gun barrel is cylindrical and hollow for placing a grease tube. The tail of the gun barrel is provided with a piston that pushes the grease tube to squeeze out the grease therein. The tail of the piston is connected to a chain that passes through the gun barrel. A compression spring is sleeved on the chain. The compression spring abuts between the piston and the tail of the gun barrel. By pulling the chain, the piston is brought close to the tail of the gun barrel and the compression spring is compressed at the same time, so that there is enough space in the gun barrel to put the grease tube. A hook is provided at the tail of the gun barrel to hook the chain, and then the gun barrel is screwed onto the gun body through a thread. When the chain is loosened, the compression spring releases its elastic potential energy to squeeze the grease tube through the piston, and the grease in the grease tube is squeezed out from the gun head.

[0003] Since the gun barrel is connected to the gun body through a thread, it takes time and effort to unscrew and tighten the gun barrel due to the large diameter of the gun barrel and the large number of threads. In addition, the gun barrel and the gun body need to be aligned with the thread when they are connected, which increases the difficulty of operation. When the gun barrel is unscrewed and separated from the gun head, the gun barrel needs to be placed specially, otherwise there is a risk of rolling off. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] See also Figures 1 to 6 This is an embodiment of a butter filling device of the utility model, which includes a box body 10 and a first placement cavity 11 arranged in the box body 10. The box body 10 is a rectangular parallelepiped structure. The first placement cavity 11 is mainly used to store the butter tube, and a box cover 20 is provided on the box body 10 to close the first placement cavity 11. A piston 30 is slidably provided in the first placement cavity 11 along the length direction, that is, the piston 30 can slide back and forth in the first placement cavity 11. A pull rope 40 is connected to the rear of the piston 30, and the end of the pull rope 40 passes through the rear side wall of the first placement cavity 11 and is connected to a ratchet winding device 50 arranged outside the box body 10, that is, the pull rope 40 can be stored by the ratchet winding device 50, thereby driving the piston 30 to slide to the rear of the first placement cavity 11. In order to ensure that the piston 30 can slide smoothly without turning over when the pull rope 40 pulls the piston 30, the pull rope 40 is generally fixed at the center of the rear of the piston 30, and a compression spring 60 is also provided between the piston 30 and the rear side wall of the first placement cavity 11. When the pull rope 40 pulls the piston 30 to move to the rear of the first placement cavity 11, the compression spring 60 is compressed to generate elastic potential energy. When the pull rope 40 is released, the compression spring 60 can push the piston 30 to slide to the front of the first placement cavity 11 to compress the butter tube. Generally, the pull rope 40 passes through the center of the piston 30, which can also be understood as the compression spring 60 being sleeved on the pull rope 40, so that the compression spring 60 and the pull rope 40 can avoid interference with each other.

[0047] A butter outlet 12 is provided at the front end of the first placement chamber 11, and the butter outlet 12 is connected to an oil outlet pipe 13. After the butter pipe is squeezed by the piston 30, the butter in the butter pipe flows from the butter outlet 12 into the oil outlet pipe 13 and is squeezed to a designated position. A pressurizing mechanism is also provided in the box body 10, and the pressurizing mechanism is connected to the oil outlet pipe 13, which can increase the pressure in the oil outlet pipe 13, so that the butter has a certain initial velocity when flowing out of the oil outlet pipe 13, and is better filled into some narrow places. Since the butter flow rate in the oil outlet pipe 13 increases, the butter filling efficiency is also improved.

[0048] Furthermore, the top of the box body 10 is provided with an opening 14 communicating with the first placement cavity 11, so that when the box body 10 is placed on the ground or on a table, the opening 14 at the top of the box body 10 is more convenient for inserting the butter tube, and the opening 14 is arranged along the length direction of the first placement cavity 11, that is, along the front-back direction of the box body 10, so that the opening 14 is as large as possible, and it is more convenient to insert the butter tube. The width of the opening 14 is less than the outer diameter of the compression spring 60, so as to prevent the compression spring 60 from escaping from the first placement cavity 11, and when the piston 30 moves to compress the compression spring 60, it can also prevent the compression spring 60 from arching, so that the direction of the elastic force generated by the compression spring 60 is always consistent with the moving direction of the piston 30.

[0049] Furthermore, a box cover 20 is hinged on the box body 10 beside the opening 14, the right side of the box cover 20 is hinged to the box body 10, and a lock is provided between the left side of the box cover 20 and the box body 10. After closing the box cover 20, the box cover 20 is locked on the box body 10 to prevent the box cover 20 from opening. The specific structure and unlocking form of the lock can refer to the lock of the existing public technology. A second placement cavity 21 is provided on the box cover 20, which is connected to the first placement cavity 11. The first placement cavity 11 and the second placement cavity 21 are spliced ​​into a filling cavity with a circular cross section, that is, the cross section of the first placement cavity 11 is a large semicircle, and the cross section of the second placement cavity 21 is a small semicircle. Although the width of the opening 14 of the first placement cavity 11 is smaller than the diameter of the filling cavity, the butter tube can produce a certain deformation, which will not affect the butter tube from being placed in the first placement cavity 11, and the cylindrical shape of the filling cavity is just consistent with the shape of the butter tube, reducing the useless space in the filling cavity. Of course, a butter tube smaller than the diameter of the filling chamber can also be placed therein for use, thus increasing the adaptability range of the filling chamber.

[0050] A handle 22 is also provided on the box cover 20. Since the box cover 20 is arranged on the top of the box body 10, the handle 22 is provided on the box cover 20 for carrying the butter filling device when in use. On the other hand, when the box cover 20 needs to be opened, the handle 22 can also be held to perform the opening operation. A control mechanism 23 for controlling the start and stop of the pressurizing mechanism is provided on the handle 22. The control mechanism 23 can control the start and stop of the pressurizing mechanism by wire or wireless means, so that the user can simultaneously operate the start and stop of the butter filling while holding the handle 22 to carry, so as to achieve one-handed carrying and control.

[0051] The pressurizing mechanism is arranged below the first placement cavity 11, that is, a pressurizing placement cavity 15 is arranged below the first placement cavity 11 in the box body 10, and the pressurizing mechanism is arranged in the pressurizing placement cavity 15, which not only reduces the width of the box body 10 and prevents the box body 10 from hitting the user when carrying, but also can move the center of gravity of the box body 10 downward, so that when placing or replacing the butter tube, the box body 10 will be placed more stably and not easy to tip over.

[0052] The pressurizing mechanism includes an electric grease pump 70 and a battery 80. The battery 80 provides power for the electric grease pump 70, and the electric grease pump 70 is connected to the oil outlet pipe 13 to provide pressure for the oil outlet pipe 13 to accelerate the flow of butter. The electric grease pump 70 and the battery 80 are fixed in the pressurizing placement chamber 15 in front and back, so that the electric grease pump 70 is located in the front and can be closer to the oil outlet pipe 13, and the front and back arrangement form fully utilizes the space in the length direction of the box body 10 and reduces the width of the box body 10. The control mechanism 23 can be a power switch, which controls the power on and off between the battery 80 and the electric grease pump 70 by wired or wireless means. The electric grease pump 70 in this embodiment includes a motor, a reducer and a piston. The motor drives the eccentric wheel through the reducer to drive the piston to reciprocate, and the head of the piston continuously pushes the butter squeezed out of the butter pipe into the oil outlet pipe 13. In addition, electric grease pumps 70 with other structures can also be used to achieve the above purpose.

[0053] like Figure 5 , Figure 6As shown, the ratchet winding device 50 can adopt the existing disclosed structure, or the following structure: it includes a fixed seat 51, a connecting shaft 52 rotatably connected to the fixed seat 51, a ratchet 53 fixedly connected to the connecting shaft 52 and a handle 54 rotatably connected to the connecting shaft 52, the fixed seat 51 is fixed to the outer wall of the box body 10, the end of the pull rope 40 passes through the box body 10 and is fixed to the connecting shaft 52, the fixed seat 51 is also provided with a pawl 55 that cooperates with the ratchet 53, and the handle 54 is provided with a paddle 56 that drives the ratchet 53 to rotate, and the paddle 56 is driven by the handle 54 to swing around the axis of the connecting shaft 52, and the paddle 56 will drive the ratchet 53 to rotate, but due to the abutment of the pawl 55, the ratchet 53 can only rotate in one direction. In this embodiment, when the handle 54 is pressed down and the paddle 56 is driven to swing downward, the paddle 56 drives the ratchet 53 to rotate, and the ratchet 53 drives the connecting shaft 52 to rotate and reel in the drawstring 40; when the paddle 56 swings back, the pawl 55 resists the ratchet 53 to prevent the ratchet 53 from rotating. The handle 54 is provided with a sliding groove, and the paddle 56 is resisted by the ratchet 53 and slides along the sliding groove to make way for the handle 54 to swing upward smoothly. Then the above process is repeated to continuously drive the ratchet 53 to reel in the drawstring 40. Since the swing of the handle 54 has a larger force arm, the reeling process is more labor-saving than directly pulling the drawstring 40, saving the user's physical strength. When it is necessary to release, adjust the paddle 56 to make way for the rotation position of the ratchet 53, and release the pawl 55. Under the action of the compression spring 60, the piston 30 is pushed forward, and the drawstring 40 is driven to be released at the same time. The pawl 55 in this embodiment is slidably set on the fixed seat 51. By controlling the sliding position of the pawl 55 on the fixed seat 51 and adjusting the cooperation between the pawl 55 and the ratchet 53, an additional elastic device such as a spring can be added to keep the pawl 55 in contact with the ratchet 53.

[0054] Furthermore, a slot 57 is provided on the fixing base 51 to cooperate with the paddle 56. When the handle 54 is not needed, the paddle 56 is adjusted to slide on the handle 54 and inserted into the slot 57 on the fixing base 51, so as to fix the relative position of the handle 54 and the fixing base 51, thereby preventing the handle 54 from swinging and getting caught on the user or other objects, and also preventing the handle 54 from swinging and being damaged by impact during transportation.

[0055] In addition, in order to more accurately apply the grease to the designated position, the oil outlet pipe 13 is connected to the grease gun 17 through the hose 16. A buckle 18 for fixing the hose 16 is provided on the side wall of the box body 10. The buckle 18 fixes the hose 16 during transportation and storage to prevent the hose 16 from being damaged.

[0056] When in use, press the lock to unlock, flip the box cover 20, open the first placement chamber 11, turn the ratchet 53 through the handle 54, reel in the drawstring 40, pull the piston 30 to slide to the rear of the first placement chamber 11, and compress the compression spring 60 at the same time, then put the butter tube into the first placement chamber 11, and align the outlet of the butter tube with the butter outlet 12; cover the box cover 20, lock the box cover 20 with the box body 10, release the ratchet 55, release the elastic potential energy of the compression spring 60, and the work before applying butter is completed. The electric grease pump 70 is controlled by the control mechanism 23 on the handle 22, and the butter is applied to the specified position by the grease gun 17. After the butter tube is used, the drawstring 40 is reeled in by the ratchet reeling device 50, the piston 30 is pulled back, the box cover 20 is opened to take out the used butter tube, and then a new butter tube is replaced, and the above operation is repeated. Through the butter filling device of this embodiment, the pull rope 40 is stored by the ratchet winding device 50, which can save more effort and reduce the risk when the pull rope 40 is released. When replacing the butter tube, only the box cover 20 needs to be opened for replacement. It is a simple operation by one person and the replacement process is faster.

[0057] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
