Description

Grease gun and its adapter ring structure

The present invention relates to a manual supply lubrication device, and in particular to a technical field applicable to different types of butter cans.

According to the existing mechanical devices, most of the lubricating oils are used to maintain the operation of various interlocking mechanical components. Among them, Grease is one of the widely used lubricating oils.

Therefore, as shown in the seventh and eighth figures, some grease guns 3 and butter cans 4 have been developed, the butter cans are loaded into the grease gun 3, and then the operating lever 311 of the cylinder 31 is pressed. In order to use the vacuum method (for example, the new patent No. M412294) or the spring force (for example, the new patent No. M449897), the butter is applied.

However, the currently commercially available butter cans 4 are roughly classified into two types, one is an easy-opening type butter can 41, the upper cover 411 is opened and then loaded into the grease gun 3 and its cartridge 31, as shown in the seventh figure. The easy-opening type butter can 41 is used; the other is a front end of the blister-type butter can 42 which is provided with a nose 421, and the protrusion 421 is provided with an external thread, by means of the protruding mouth 421 Combined with the barrel of another grease gun. However, the structure of the cylinder is different from the structure of the above-mentioned cylinder 31. Therefore, it is necessary to develop a grease gun which can be applied to different types of butter cans 41 and 42 to benefit the user.

In view of the above problems with the conventional grease gun. Therefore, the main purpose of the novel is to provide a grease gun and its adapter ring structure for different styles of butter cans.

In order to achieve the aforementioned purpose, the novel grease gun and its adapter ring structure are used. The technical means, the adapter ring structure comprises: a ring body, the ring body has a class-like outer surface and comprises a flange portion, and the ring body has a class-shaped inner hole, and the class-shaped inner hole The utility model is composed of a large inner hole and a small inner hole; an external thread is arranged on the flange portion of the ring body; and an internal thread is arranged on the large inner hole of the ring body; a first outer diameter and a second outer diameter are respectively disposed on two sides of the flange portion of the body, and the first outer diameter, the second outer diameter, and the flange portion constitute an outer surface of the ring body shape, and the flange is A plurality of curved ribs are disposed between the second portion and the second outer diameter.

In addition, a grease gun uses the above-mentioned adapter, which comprises: the above-mentioned adapter ring; a cylinder is provided with a joint portion at the bottom of the body, and a passage is provided inside the body and leads to the An outlet at the top of the body and an inlet at the bottom of the body, and a piston is disposed in the channel, and an outer end of the piston is pivotally connected to an intermediate portion of the operating rod, and the operating rod is pivotally connected to the body by a connecting rod The top portion further constitutes a four-link structure; and a barrel body is sleeved at one end of the joint portion of the barrel.

The grease gun further includes a gasket having an inner hole, and the inner hole of the gasket is sleeved on the first outer diameter of the adapter ring.

The joint portion of the barrel is provided with an internal thread, and one end of the barrel tube is provided with an external thread.

Compared with the prior art, the grease gun and its adapter ring structure have the following effects by the above technical means: the present invention uses the adapter ring to use the adapter ring to make the adapter ring large. The external thread of the inner hole is combined with the protruding mouth of the Philippian butter can, and the butter of the grease gun is used to make butter. If the grease gun does not use the adapter ring, the easy-open can butter can be used directly. Therefore, the grease gun of the present invention can be applied to different types of butter cans.

First, please refer to the first figure and the fifth figure, which is a new type of grease gun and its adapter ring structure, wherein the adapter ring 1 is structured as shown in the third and fourth figures, wherein The ring body 11 includes a flange-shaped outer surface and includes a flange portion 13. The flange portion 13 is provided with an external thread 14 and the ring body 11 has a stepped shape. The hole 12 and the stepped inner hole 12 are formed by a large inner hole 121 and a small inner hole 122, and an internal thread 15 is also provided in the large inner hole 121. Further, the first outer diameter 16 and the second outer diameter 17 are respectively disposed on both sides of the flange portion 13 of the ring body 11, that is, the first outer diameter 16, the second outer diameter 17, and the flange portion 13 constitute the ring. The outer surface of the body 11 is formed with a plurality of curved ribs 18 between the flange portion 13 and the second outer diameter 17 to strengthen the structural strength of the adapter ring 1.

In addition, the grease gun 2 of the present invention uses the adapter ring 1 as shown in the second, fifth, and sixth figures, and the structure of the grease gun 2 includes: the adapter ring 1, a cylinder 21, a barrel 22 and a gasket 23; wherein the barrel 21, as shown in the sixth figure, is provided with a joint portion 211 at the bottom of the body 210, and the joint portion 211 is provided with an internal thread 212, and The inside of the body 210 is provided with a passage 213 and an outlet 214 at the top of the body 210 and an inlet 215 at the bottom of the body 210. A piston 216 is disposed in the passage 213, and the piston 216 is external. The end is pivotally connected to an intermediate portion of the operating rod 217, and the operating rod 217 is pivotally connected to the top of the body 210 by a connecting rod 218 to form a four-bar linkage structure, thereby facilitating actuation of the piston 216 by operating the lever 217. Horizontally moving horizontally within the channel 213.

The barrel body 22, as shown in the second and fifth figures, is attached to the joint portion 211 of the cartridge 21 at one end. Further, the internal thread 212 is disposed in the joint portion 211 of the cartridge 21, and one end of the barrel tube 22 is provided with an external thread 221, so that the barrel portion 22 is connected to the joint portion 211 of the cartridge 21, because The barrel tube 22 has a relatively high hardness and is convenient for the user to hold. As shown in the sixth figure, the inner hole 231 of the gasket 23 is sleeved on the first outer diameter 16 of the adapter ring 1, so that the adapter ring 1 is sealed to the bottom of the cylinder 21, The butter of the anti-cream tank 4 is leaked.

Referring to the fifth and sixth figures, the inner hole 231 of the adapter ring 1 of the adapter ring 1 is first inserted into the structure of the grease gun 2 and the adapter ring 1 thereof. The first outer diameter 16 of the adapter ring 1 is then inserted into the gun body 22 after the adapter ring 1 is sleeved into the nozzle 421 of the syrian butter can 42 The external thread 221 of the barrel tube 22 is locked to the internal thread 212 of the joint portion 211 of the cartridge 21. Continuing, the cylinder 21 is continuously pressed to continuously actuate the piston 216 to reciprocate horizontally in the passage 123, and the excess air is blown out, that is, the vacuum can be used to butter the blizzard butter pot 42
