Description

Regenerative Gas Generator of Automatic Lubricant Lubricator

The present invention relates to a device for automatically injecting lubricating oil, and in particular, it is possible to reuse new metal reactants by inserting them into the case and assembling the separated parts, and to uniformly supply the lubricating oil by keeping the amount of gas generated uniformly. The present invention relates to a regenerative gas generator of an automatic lubricator.

In general, a device that performs a predetermined link motion generates friction between different members continuously while rotating or sliding, and heat is generated in the friction part when a certain lubricant is not supplied to the friction part. Breakage occurs between metals.

Lubricating oils having various viscosities are used to prevent friction between such apparatuses. Greases, such as lubricants close to liquids and lubricants close to solids, are extracted from plants and minerals and used for various purposes.

In particular, if a person cannot supply lubricant easily, but supplies a certain amount of lubricant over a long period of time such as a roller coaster for an amusement park, for example, a roller coaster in an amusement park, the gas is continuously used. For example, a lubricating oil supply device for supplying a predetermined amount of lubricating oil by a predetermined amount for a period of about one month is used.

1 is a cross-sectional view showing a state of engagement of a conventional automatic lubricating oil dispenser (Patent Publication No. 96-23991), Figure 2 is a cross-sectional view showing a gas generating input device of a conventional lubricating oil automatic lubricator, looking at the configuration of the conventional device, Cylindrical housing 102, the upper portion of which is opened and the filling hole 101 is opened downward, and a piston 103 embedded in the cylindrical housing 102 to be in close contact with the bottom surface and the side wall of the cylindrical housing 102. And an expansion container 104 filled with an electrolyte in the gas expansion space 105 therein and fixed to an upper end of the cylindrical housing 102, and combined with an upper portion of the cylindrical housing 102 and placed in the center 107. ) Is coupled to the inlet 108, the lid 106 having the membrane 109, and the inlet 108 of the lid 106 to expand the gas generating metal reactant 110 into the expansion vessel 104. It is composed of an input device 107 to be administered to the electrolyte solution.

Look at the operation of the conventional lubricating oil automatic lubricator configured as described above.

First, when the feeding device 107 is rotated against the feeding hole 108, the screw portion of the feeding hole 108 and the screw portion of the feeding device 107 are screwed together so that the feeding device 107 is engaged with the feeding hole 108 The device 107 is lowered to the bottom of the inlet 108.

Subsequently, when the inner wall of the feeding hole 108 presses the protrusion 112 of the feeding device 107, the protrusion 112 is introduced into the inside of the feeding device 107 about the rotation shaft 113. The pressure unit 114 is opened around the rotation shaft 113.

In addition, the cutting protrusion formed on the lower end of the feeding device 107 contacts the membrane 109 and rotates to fold the membrane 109.

Accordingly, the gas generating metal reactant 110 fixed to the feeding device 107 by the pressing unit 114 is introduced into the electrolyte filled in the expansion container 104 through the cut film 109 and the gas is supplied. As it is generated, the gas expansion space 105 is increased.

Subsequently, the piston 103 descends while pushing the lubricating oil filled in the interior of the housing 102 by the pressure of the gas into the oil inlet 101 so that the lubricating oil can be continuously supplied to the portion to be lubricated by a predetermined amount. to be.

By the way, in the conventional device configured as described above, when the expansion rubber is inflated, the engaging portion of the expansion rubber that is caught in the housing is caught only by the lower side, so that the locking portion may be separated by the expansion pressure. Since the manufacturing process of the molten metal material is complicated and the gas generation amount varies depending on the position where the metal material is placed on the expanded rubber film, the supply amount of the lubricating oil was not constant.

In addition, since the device is not reusable after one use, not only the amount of industrial waste is generated but also a large amount of treatment costs, and has a problem of polluting the environment when proper treatment is not performed.

Therefore, the present invention has been devised in view of this point, and in supplying the metal reactant to the electrolyte, when the screw member coupled to the cover is turned, the cover rubber stopper fixed to the cover is opened by the pressing protrusion of the screw member. Since the metal reactant stored in the case reacts with the electrolyte solution stored in the expanded rubber membrane, gas is generated and consumed. Therefore, it is possible to reuse the device by simply inserting a new metal reactant into the case and assembling the separated parts. The purpose is.

In addition, another object of the present invention is to uniformly maintain the supply amount of lubricating oil by making the gas pressure applied to the expanded rubber film uniform.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the present invention.

Looking at the configuration of the present invention, the body 10 is formed with a discharge port 12 for supplying the lubricating oil stored in the center; In the lubricating oil automatic lubricator consisting of a piston 20 inserted into the body 10 to pressurize the lubricating oil to the piston o-ring 22 of the outer circumferential surface, is inserted into the inner surface of the piston 20 and pressurized in a hemispherical shape to the contact portion An expanded rubber film 30 forming a portion 36 and forming a locking protrusion 32 protruding up and down at both edges thereof; Inserted into the body 10 is the locking projection 32 of the expansion rubber membrane 30 is caught by the locking jaw portion 56, the lower cover o-ring 52 is installed on the lower outer peripheral surface and the upper cover 54, the upper cover o-ring A cover 50 on which the 59 is installed; A cover rubber stopper 40 inserted and fixed by an insertion groove 42 at a lower inlet portion of the cover 50; The male screw portion 84 is fastened to the female screw portion 58 of the cover 50 to move up and down, and a guide groove 86 is formed in the longitudinal direction at the end thereof, and a pressing protrusion 88 is formed at the center bottom. A screw member 80 having a working screw o-ring 82 formed on an upper circumference of the male screw part 84; A guide protrusion 72 is formed to be inserted into the guide groove 86 of the screw member 80, and reacts with the electrolyte stored in the electrolyte storage unit 34 of the expanded rubber membrane 30 to generate gas. The material 60 is composed of a case 70 which is inserted and fixed in the central portion.

In addition, the metal reactant material 60 inserted into and fixed to the case 70 forms an electrode 62 with a predetermined length drawn out to one side of the central part so that the metal reactant material 60 uniformly and uniformly bubbles when it reacts with the electrolyte solution. It serves to generate.

In addition, the pressurizing portion 36 of the expanded rubber film 30 is formed in a shape in which the central portion is thickest and slightly thinner toward both sides, so that the piston 20 and the expanded rubber film 30 are expanded by gas. The contact area of the is widened so that the pressure to pressurize the piston 20 is uniform so that the piston 20 moves without tilting.

Hereinafter, look at the operation of the present invention in detail.

Looking at the assembly state of the present invention, the very viscous lubricating oil is injected into the body 10, the piston O-ring 22 to insert the piston 20 installed on the outer peripheral surface to the body 10.

When the expansion rubber membrane 30 is tightly fixed on the piston 20, the lower locking protrusion 32 is caught by the lower locking groove 14 of the body 10. The electrolyte is stored in the electrolyte storage unit 34 of the expanded rubber membrane 30.

On the other hand, when the cover 50 is inserted into the expansion rubber film 30, the upper locking projection 32 of the expansion rubber film 30 is fixed in a state that is caught on the locking jaw portion 56 of the cover 50 Lose.

Then, the case 70 in which the metal reactant 60 is inserted is fixed to the guide groove 86 of the screw member 80, and then the male thread portion 84 is the female thread portion 58 of the cover 50. To be tightened.

Looking at the state of use of the subject innovation in the assembled state as described above, the screw member 80 is rotated as shown in Figure 6a to ensure that the lubricating oil is uniformly and uniformly injected into the discharge port 12 of the body 10, When tightened, the male screw portion 84 enters the lower side while being fastened to the female screw portion 58 of the cover 50.

Then, the guide projection 72 of the case 70 is caught by the central jaw portion of the cover 50 and the lower movement is prevented while the guide 72 of the case 70 opens the guide groove 86 of the screw member 80. Therefore, it moves upward.

At this time, the pressing protrusion 88 of the screw member 80 pushes the metal reactant 60 fixed in the case 70 downward, and the metal reactant 60 pushed downward is contacted with the lower surface. The cover rubber stopper 40 is pushed downward and separated from the cover 40 to be moved to the expanded rubber membrane 30.

And, as shown in Figure 6b, when the screw member 80 is completely coupled to the cover 50, the metal reactant 60 is also moved to the electrolyte storage portion 34 of the expanded rubber film 30 and At the same time, bubbles are gradually generated while reacting with the electrolyte solution. The electrode is drawn out in the center portion of the metal reactant 60 to adjust the gas generation amount according to the length of the electrode 62. That is, when the length of the electrode 62 is short, the amount of bubble generation is small, and when the length of the electrode 62 is long, the amount of gas generation can be adjusted.

On the other hand, as the expansion rubber membrane 30 expands downward by the generation of gas, the piston 20 is pushed downward, and the piston 20 pressurizes the lubricating oil in the body 10 and gradually moves to the discharge port 12. Uniformly supplying lubricating oil in the right place in the instrument.

At this time, since the thickness of the central portion of the pressurizing portion 36 of the expansion rubber film 30 is thicker, the pressure for pressing the piston 20 during expansion is uniform, and the locking protrusion 32 protrudes upward and downward to the body ( Since it is simultaneously caught by the lower locking groove 14 and the locking jaw portion 56 of the cover 50, the separation of the fixed portion is prevented despite the severe expansion of the expanded rubber membrane 30.

On the other hand, the present invention is to disassemble the main part after the supply of the lubricating oil is stored to store the lubricating oil in the body 10 and to store the electrolyte in the expansion rubber membrane 30, cover rubber stopper 40 on the cover 50 And a new metal reactant 60 in the case 70 can be reassembled and used.

7A and 7B illustrate a state in which a metal reactant generates gas by an electrolyte solution according to the prior art and the present invention. In the conventional case, as shown in FIG. 7A, an electrode is disposed at a central portion of the metal reactant 110. Is formed (see German Patent Registration 4414672) or, as another embodiment, when the electrode is formed on the entire portion of the metal reactant (110 ') to generate gas in the entire surface in contact with the electrolyte (Japanese Patent Since the gas generation amount varies depending on the position where the metal reactants 110, 110 'are placed, the amount of movement of the piston 103 is not constant, so that the supply of lubricating oil is not uniform. In the case of the present invention, as shown in FIG. 7B, the electrode 62 withdrawn from the metal reactant 60 is exposed to the electrolyte solution regardless of the position placed on the bottom surface of the expanded rubber film 30. Occur Is always maintained constant is the supply of the lubricant constant.

In this case, although the electrode 62 withdrawn from the metal reactant material 60 of the present invention is illustrated in a bent shape, the electrode 62 may be formed in a straight line if necessary.

Therefore, when using the regeneration type gas generator of the lubricating oil automatic lubricator according to the present invention as described above, by turning the screw member coupled to the cover, the cover rubber stopper fixed to the cover is opened by the pressing protrusion of the screw member Since the metal reactant stored in the gas reacts with the electrolyte solution stored in the expanded rubber membrane, gas is generated. By inserting new metal reactant into the case and assembling the separated parts, it is possible to reuse it, thus reducing the generation of waste and preventing environmental pollution. It is a very useful and effective design.

In addition, the locking action of the locking projections formed on the expanded rubber membrane is improved, and the pressure portion formed with a different thickness ensures the operation of the piston accurately, so that the lubricating oil can be smoothly supplied and the direction in which the metal reactant is placed on the expanded rubber membrane. Irrespective of the amount of gas generated due to the electrode, the pressure applied to the piston is uniform, which has the advantage that the lubricating oil is continuously made the same.
