Description

Technical Field

[0001] This utility model relates to the field of butter dispensing technology, specifically to a butter dispensing device. Background Technology

[0002] A grease filling device is a device used to accurately and conveniently add grease (lubricating grease) to the lubrication points of various equipment and mechanical parts, so as to lubricate and protect mechanical parts, reduce friction and wear, and extend the service life of equipment.

[0003] Grease filling devices are generally divided into manual grease guns, electric grease guns, pneumatic grease guns, and foot-operated grease guns. Manual grease guns use intermittent pressing of the handle to squeeze out the lubricating grease from the cylinder by utilizing the internal components such as the rubber cup, spring, and steel column. Electric and pneumatic grease guns, on the other hand, use electric or pneumatic power to squeeze out the lubricating grease from the cylinder using a plunger or airflow.

[0004] In actual use, the manual grease guns in the prior art require users to press and release continuously, and the long-term frequent pressing can easily cause hand and arm fatigue. Pneumatic and electric grease guns, on the other hand, require the use of electric and air pressure compression devices, which reduces the ease of use of the grease dispensing device.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a grease dispensing device, including a cylinder 1, with a discharge port 11 fixedly connected to one end of the cylinder 1, and a first pressure plate 12 inserted inside the end of the cylinder 1 away from the discharge port 11. A pressing assembly 2 is provided at the end of the cylinder 1 away from the discharge port 11, and the pressing assembly 2 includes a second pressure plate 21 disposed on the outer side of the end of the cylinder 1 away from the discharge port 11. A first sealing gasket 22 is fixedly connected to the end of the second pressure plate 21 near the cylinder 1, and the outer sides of the second pressure plate 21 and the first sealing gasket 22 are... The device includes a ventilation assembly 3, a transmission assembly 4 at the end of the second pressure plate 21 away from the cylinder 1, a rotating assembly 5 at the end of the transmission assembly 4 away from the second pressure plate 21, a rocking assembly 6 at one end of the rotating assembly 5, and a sealing assembly 7 at the end of the cylinder 1 near the ventilation assembly 3. By cooperating with the extrusion assembly 2 and the ventilation assembly 3, the grease lubricating oil inside the cylinder 1 can be easily squeezed out while reducing arm fatigue during extrusion. At the same time, it does not require external pneumatic or electric equipment, effectively improving the convenience of use.

[0024] like Figure 1 and Figure 2As shown, the ventilation assembly 3 includes a second pressure plate 21 and a protective cover 31 sleeved on the outside of the first sealing gasket 22. The protective cover 31 has a first air inlet 32 ​​at one end near the cylinder 1 and a second air inlet 33 at the other end away from the cylinder 1.

[0025] like Figure 3 As shown, the transmission assembly 4 includes a first connecting rod 41 fixedly connected to the end of the second pressure plate 21 away from the first sealing gasket 22, and a second connecting rod 42 rotatably connected to the end of the first connecting rod 41 away from the second pressure plate 21. A collar 43 is sleeved on the outer side of the end of the first connecting rod 41 near the second pressure plate 21, and a first connecting plate 44 is fixedly connected to the end of the collar 43 away from the first connecting rod 41. The end of the first connecting plate 44 near the protective cover 31 is fixedly connected to the protective cover 31. After the adapter 51 rotates, it drives the second connecting rod 42 to rotate. After the second connecting rod 42 rotates, it drives the first connecting rod 41 to reciprocate under the restriction of the collar 43 and the first connecting plate 44 through the rotatable connection with the first connecting rod 41.

[0026] like Figure 3 As shown, the rotating assembly 5 includes a transition piece 51 rotatably connected to the end of the second connecting rod 42 away from the first connecting rod 41, and a first gear 52 is fixedly connected to the end of the transition piece 51 away from the second connecting rod 42. The end of the first gear 52 away from the transition piece 51 is rotatably connected to the cover 31. The first gear 52 and the transition piece 51 are rotated by the meshing of the second gear 61 with the first gear 52.

[0027] like Figure 3 As shown, the rocking assembly 6 includes a second gear 61 meshing with one end of the first gear 52, and a turntable 62 fixedly connected to the middle end of the second gear 61. A crank handle 63 is rotatably connected to the end of the turntable 62 away from the second gear 61, and the end of the turntable 62 close to the second gear 61 is rotatably connected inside the protective cover 31. By holding the crank handle 63, the turntable 62 is rotated, thereby causing the turntable 62 to synchronously drive the second gear 61 to rotate.

[0028] like Figure 4 As shown, the sealing assembly 7 includes an externally threaded sleeve 71 fixedly connected to the outer side of the end of the cylinder 1 near the protective cover 31, and an internally threaded sleeve 72 engaged on the inner side of the end of the externally threaded sleeve 71 away from the cylinder 1. The end of the internally threaded sleeve 72 near the protective cover 31 is fixedly connected to the protective cover 31. The cylinder 1 is installed by screwing the externally threaded sleeve 71 into the internally threaded sleeve 72.

[0029] like Figure 4As shown, a second connecting plate 73 is fixedly connected to the inner end of the internal threaded sleeve 72 near the protective cover 31, and a second sealing gasket 74 is fixedly connected to the side of the second connecting plate 73 near the external threaded sleeve 71. The side of the second sealing gasket 74 away from the second connecting plate 73 is fitted to the external threaded sleeve 71, and the connection between the external threaded sleeve 71 and the internal threaded sleeve 72 is sealed by the second connecting plate 73 and the second sealing gasket 74.

[0030] Working principle: When extruding lubricating grease from the cylinder 1, first hold the cylinder 1, then hold the crank handle 63 with the other hand. Crank the handle 63 to rotate the turntable 62 and the second gear 61. The second gear 61, after rotating, meshes with the first gear 52, causing the first gear 52 to rotate the adapter 51. The adapter 51, after rotating, drives the second connecting rod 42. The second connecting rod 42, after rotating, connects with the first connecting rod 41, causing the first connecting rod 41 to reciprocate under the constraint of the collar 43 and the first connecting plate 44. The reciprocating movement of the first connecting rod 41 drives the second pressure plate 21 and the first sealing gasket 22 to reciprocate. When the second pressure plate 21 and the first sealing gasket 22 reach the top, external air enters the protective cover 31 through the first air inlet 32. As the second pressure plate 21 and the first sealing gasket 22 move downwards, the second pressure plate 21 and the first sealing gasket 22... After the pad 22 moves past the first air inlet 32, the air at one end of the cover 31 is compressed by the second pressure plate 21 and the first sealing gasket 22. The compressed air passes through the external threaded sleeve 71 and the internal threaded sleeve 72 and enters the cylinder 1. At this time, the compressed air squeezes the first pressure plate 12, thereby squeezing the lubricating grease in the cylinder 1, so that the lubricating grease is squeezed out from the outlet 11. When the second pressure plate 21 and the first sealing gasket 22 return to their original positions, they can be quickly returned to their original positions through the slot at the first air inlet 32. When the cylinder 1 is replaced, the external threaded sleeve 71 is screwed out to remove the internal threaded sleeve 72, and the replaced external threaded sleeve 71 is screwed into the internal threaded sleeve 72. Subsequently, the second connecting plate 73 and the second sealing gasket 74 enhance the sealing at the connection between the external threaded sleeve 71 and the internal threaded sleeve 72.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
