Description

[0001] The present invention relates to an arm joint device using a bearing,

More particularly, the present invention relates to an earthing joint apparatus using a bearing, which is simple in structure and easy to manufacture, can be easily assembled with a simple assembly ball, thereby improving convenience, light weight, and miniaturization, To a wearable jointing device using bearings which can reduce the life of the joint due to frictional resistance and can be used for a long time.

In general, awning is installed in an entrance, a window, or a show window of a building to prevent direct sunlight or rainwater, thereby facilitating access or providing a comfortable room.

This kind of performance enhances the outdoor space of the store as well as the protection of the loaded goods in the store, and is also used as a means of advertisement while visually circulating the surroundings in a color matching with the surrounding environment.

Such an affirmation is provided with a variable-type shade so that the shade can maintain its original color even in direct sunlight and withstand strong winds.

For example, as shown in FIG. 1, the conventional erection installation structure includes a main frame 110 fixed to a wall of a building through a plurality of fixing members 120, and an arm bracket The first arm 170 is rotatably hinged to the first arm 170 using the first arm 170 and the second arm 180 is connected to the end of the first arm 170 and the arm joint 130 is connected to the end of the first arm 170, The end of the second arm 180 is linked to the front frame 100 and the winding drum 150 on which the ornament film 160 is wound is fixed to the upper side of the main frame 110 by a fixing bracket 190 The first and second arms 170 and 180 are folded and unfolded by pulling the end portion of the waving film 160 pulled out from the winding drum 150 to the front frame 100 to pull out the winging film 160, Function, i.e., an erasing function.

However, since the first arm 170, the second arm 180, and the arm joint 130 are formed of steel structures, they are heavy and very heavy and difficult to install due to the corrosion, There was a high risk of safety accidents due to injuries caused by collision with heavy objects.

In addition, since the arm joint 130 constituting the joint region is made of a steel structure, it is necessary to apply the lubricant every time by moving it with a simple pin connection, but it is difficult to inject the lubricant because it is suspended in the air There is also a disadvantage that it becomes very difficult to unfold and fold Ernie by avoiding troublesome.

At this time, the first joint member 10, the second joint member 20, and the rotation axis member RO are molded into a durable synthetic resin mixture.

Therefore, it becomes possible to reduce the weight of the earring joint device. However, concrete synthetic resin mixtures will be described later.

As shown in FIG. 3, the first joint member 10 is formed with a pair of fitting guides 12 having a ring shape protruding from one side.

That is, the fitting guide 12 has a roughly "gentle" shape when viewed in a normal section.

The first bearing insertion groove 14 is formed at a predetermined depth in the center of the fitting guide 12 and the inner bearing surface of the first bearing insertion groove 14 is formed with a diameter The first shaft hole 16 is formed through the through hole.

Therefore, a first bearing seating surface 18 is formed between the first shaft hole 16 and the first bearing insertion groove 14. [

A first ball bearing (50) is inserted into the first bearing insertion groove (14).

The rotating shaft member RO is divided into the base rotating shaft 30 and the assembling rotating shaft 40 so as to be assembled with each other .

In other words, they are inserted through the first shaft hole 16 from the outside of the fitting guide 12, and then assembled together to constitute a hinge shaft.

To this end, the base rotary shaft portion 30 includes a disk-shaped base shaft head 32 having a radius larger than that of the first bearing insertion groove 14, An inner diameter of the first ball bearing 50 and a shaft pin 34 inserted through the first shaft hole 16 and a coupling hole 36 formed at a predetermined depth in the inner surface of the shaft pin 34, ).

In addition, the oxycarboxylate is added to reduce moisture content of the material to reduce voids and thereby increase strength.

The polyoxyethylene is a kind of polyether obtained by polymerizing ethylene oxide by using a cation catalyst, and is added to suppress the generation of static electricity.

In addition, the propylene glycol is hygroscopic, but is not volatile and is stable to heat and light. Therefore, the propylene glycol is used as a solvent for dissolving a resin and mixing with water, and added to prevent fungal growth on the surface.

Further, the sepiolite is called a meerschaum, which is a round tubular variant, and is added to induce dispersion stability and uniform dispersion of the resin composition.

The melamine cyanate is added to reinforce heat resistance. Tetraisopropyltitanate is a coupling agent having an organic titanate structure, which enhances the interfacial adhesion between the polymer resin and the inorganic substance, thereby enhancing both durability and heat resistance.

Further, the behenic acid is added in order to enhance the lubricity of the resin and improve the moldability.

In addition, the octyltin mercaptide functions as a stabilizer for improving processability and preventing deterioration, and is added to maintain heat resistance, blooming resistance, oil resistance, activity, and weatherability.

The triethanolamine is a weakly alkaline buffer added to control acidity, and petrolatum is an ointment-like material composed mainly of amorphous solid hydrocarbons and is waterproof and added to enhance the formation.

In addition, the attapulgite is added for enhancing the elasticity and increasing the heat resistance according to the elongation improvement due to the fibrous structure.

In addition, the polybutene is added to enhance resistance to ultraviolet light resistance and resistance to discoloration.

Finally, the dioctyl azide (DOA) is added to increase the plasticity of the resin.

The synthetic resin mixture thus formed was molded into a sheet to form a sample, and then subjected to a total of 500 times and 1,000 times of testing in a facility capable of being subjected to 25 times per minute using an eccentric shaft and a speed reducer for durability test As a result, it was confirmed that there was no crack or breakage and it was durable.

In addition, the sample was allowed to stand for 30 days while exposed to ultraviolet rays, but no discoloration occurred.

Then, I hit the hammer 10 times, but it did not break.
