Abstract
Description
Technical Field
[0001] This utility model relates to a grease storage device, and more specifically to an anti-oxidation grease storage device. Background Technology
[0002] Lubricating grease, a crucial lubricating material widely used in industry, automotive, aerospace, and many other fields, plays a vital role in the normal operation of mechanical equipment. Currently, ordinary plastic containers are commonly used for storing grease. While this traditional storage method has advantages such as low cost, easy access, and convenience, it also has serious drawbacks. Because ordinary plastic containers are not specifically designed for long-term grease storage, their simple structure and poor sealing fail to effectively prevent air from contacting the grease. When grease is exposed to air for extended periods, it undergoes an oxidation reaction with oxygen. This oxidation process alters the chemical structure of the grease, gradually degrading its performance.
[0003] With the continuous development of industry, the requirements for the performance of lubricating grease are becoming increasingly stringent. Oxidized and deteriorated lubricating grease not only fails to meet the lubrication needs of equipment but may also cause a series of equipment failures and safety hazards. Therefore, there is an urgent need for a storage device that can effectively prevent the oxidation and deterioration of lubricating grease to ensure the stability of its quality during storage. Utility Model Content
[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides an anti-oxidation grease storage device.
[0005] The technical implementation of this utility model is as follows: an anti-oxidation grease storage device, including a base and a storage tank disposed on the top of the base for storing grease. The upper end of the storage tank is provided with an end cap. The base has a cavity with a front opening, and a receiving drawer is provided in the cavity. Vertical holes are provided on the top of the base and the bottom of the storage tank to connect the cavity and the storage tank. The top of the base is also provided with a horizontal sliding cavity communicating with the vertical hole. A sealing plate for sealing the vertical hole and a spring acting on the sealing plate are provided in the horizontal sliding cavity. By changing the position of the sealing plate in the horizontal sliding cavity, the opening or closing of the vertical hole can be controlled. The bottom of the sealing plate is provided with an upper protrusion. The top of the base is provided with a sliding groove adapted to the upper protrusion. The upper protrusion extends downward along the sliding groove into the cavity. A lower protrusion is provided on the receiving drawer. The upper protrusion is located on the path of the lower protrusion.
[0006] More preferably, a guide post is provided in the horizontal sliding cavity along the direction of movement of the sealing plate, the guide post is slidably connected to the sealing plate, and the spring is sleeved on the guide post.
[0007] More preferably, the upper end of the rear side of the receiving drawer is provided with a notch, and the bottom of the notch is provided with a vertical baffle. The lower protrusion is movably disposed in the notch by a pin, and a limiting part is provided on one side of the lower protrusion. A corresponding limiting groove is provided on one side of the vertical baffle. When the lower protrusion is rotated counterclockwise around the pin, the limiting part is embedded in the limiting groove. At this time, the height of the highest point of the lower protrusion is greater than the height of the upper side of the receiving drawer, and there is interference with the upper protrusion on the running path. When the lower protrusion is rotated clockwise around the pin, the lower protrusion is embedded in the notch. At this time, the height of the highest point of the lower protrusion is less than the height of the upper side of the receiving drawer.
[0008] More preferably, the end cap is fastened to the upper end of the storage hopper, and a drive motor is provided on the top of the end cap. The output shaft of the drive motor is connected to a lead screw, which is located inside the storage hopper and coaxial with it. A nut is provided on the lead screw, and a circular pressure plate is movably provided on the outer ring of the nut. A limit rod is provided on the side wall of the circular pressure plate, and a vertical groove adapted to the limit rod is opened on the inner wall of the storage hopper along its axial direction.
[0009] More preferably, the storage tank has an inlet at the top, a filling funnel is provided at the inlet, and a sealing cap is provided at the opening of the filling funnel.
[0010] More preferably, the storage hopper has a vent hole at the top, a vent pipe is installed at the vent hole, and an air valve is installed at the opening of the vent pipe.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. The storage hopper of this utility model is used to store lubricating grease. The relatively sealed environment can reduce the contact between the lubricating grease and the air. When taking out the lubricating grease, the vertical hole is opened by pushing the sealing plate through the receiving drawer, so that the lubricating grease flows into the receiving drawer along the vertical hole. Through the cooperation between the sealing plate and the receiving drawer, the contact time and contact area between the lubricating grease and the air during the taking out process are reduced, thereby providing a stable storage environment.
[0013] 2. This utility model uses a drive motor to drive the lead screw to rotate, and the nut set on the lead screw drives the circular pressure plate to move axially along the storage barrel, thereby squeezing the grease in the storage barrel out along the vertical hole, thus improving the discharge efficiency.
[0014] 3. The feed inlet of this utility model facilitates the addition of grease to the storage tank, and the vent valve facilitates the balancing of pressure difference during filling or material removal. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] To address the problem of poor protective performance in existing grease storage devices, which leads to easy oxidation and deterioration of grease, this invention proposes an oxidation-resistant grease storage device, such as... Figure 1-5 As shown, it includes a base 1 and a storage tank 2. The base 1 supports the storage tank 2, placing it at a certain distance from the ground. The storage tank 2 is installed on top of the base 1 and is used to store lubricating grease. An end cap 21 is provided at the upper end of the storage tank 2. The end cap 21 and the storage tank 2 form a relatively sealed space, isolating the lubricating grease from the air and reducing the risk of oxidation. See reference for details. Figure 2As shown, the base 1 has a front-opening chamber 11, inside which a receiving drawer 3 is provided. Vertical holes 4 are provided at the top of the base 1 and the bottom of the storage tank 2, connecting the chamber 11 and the storage tank 2. The purpose of the vertical holes 4 is to allow the grease in the storage tank 2 to flow into the receiving drawer 3 in the chamber 11, thus completing the material retrieval. In addition, a sealing plate 5 is provided to seal the vertical holes 4. The sealing plate 5 is disposed in a horizontal sliding cavity 12 at the top of the base 1, which communicates with the vertical holes 4 on the base 1. The sealing plate 5 can slide within the horizontal sliding cavity 12. By changing the position of the sealing plate 5 in the horizontal sliding cavity 12... The position of cavity 12 can control whether the vertical hole 4 is open. The horizontal sliding cavity 12 is also provided with a spring 51 acting on the sealing plate 5. One end of the spring 51 abuts against the side wall of the horizontal sliding cavity 12, and the other end abuts against the sealing plate 5. Through the action of the spring 51, the sealing plate 5 is driven to keep the vertical hole 4 in a normally closed state. Furthermore, the bottom of the sealing plate 5 is provided with an upper protrusion 52, and the top of the base 1 is provided with a sliding groove adapted to the upper protrusion 52. The upper protrusion 52 extends downward along the sliding groove into the cavity 11. Correspondingly, a lower protrusion 6 is provided on the receiving drawer 3, and the upper protrusion 52 is located on the path of the lower protrusion 6.
[0023] In one specific embodiment, reference Figure 2 and Figure 4 A guide post 53 is provided inside the horizontal sliding cavity 12 along the moving direction of the sealing plate 5. The guide post 53 is slidably connected to the sealing plate 5, and the spring 51 is sleeved on the guide post. There are two guide posts 53, distributed on both sides of the sealing plate 5, and there are also two corresponding springs 51.
[0024] By pushing the receiving drawer 3 into the chamber 11, the lower protrusion 6 drives the upper protrusion 52 to move inward synchronously, which in turn drives the sealing plate 5 to move along the reaction force of the spring 51, thereby opening the vertical hole 4. The grease stored in the storage tank 2 flows into the receiving drawer 3 along the vertical hole 4 by its own weight, thus completing the grease dispensing. When the force acting on the upper protrusion 52 is removed, the sealing plate 5 can close the vertical hole 4 again through the spring 51.
[0025] Traditionally, when taking grease, the end cap 21 is usually opened and the grease is taken directly from the opening of the storage tank 2. This allows air to come into contact with the grease, increasing the possibility of oxidation. In contrast, the grease taking method of this device reduces the probability of the grease coming into contact with air, thus providing a better grease storage environment.
[0026] refer to Figure 1In one specific embodiment, the storage tank 2 has an inlet at its upper end, and a packing funnel 8 is provided at the inlet. A sealing cap 81 is provided at the opening of the packing funnel 8. Additionally, a vent hole is provided at the upper end of the storage tank 2, and a vent pipe 9 is provided at the vent hole. An air valve 91 is provided at the opening of the vent pipe 9. The packing funnel 8 allows for convenient addition of lubricating grease to the storage tank 2, while the vent hole and air valve 91 help to expel air from the storage tank 2 or balance the internal and external air pressure of the storage tank 2.
[0027] refer to Figure 3 A notch 31 is provided at the upper rear end of the receiving drawer 3. A vertical baffle 32 is provided at the bottom of the notch 31. The lower protrusion 6 is movably disposed in the notch 31 via a pin 61. The lower protrusion 6 can rotate clockwise or counterclockwise along the pin 61. In addition, a limiting part 62 is provided on one side of the lower protrusion 6, and a limiting groove 33 corresponding to the limiting part 62 is provided on one side of the vertical baffle 32. Figure 3 Based on the reference, observing the lower protrusion 6 from right to left, when the lower protrusion 6 is rotated counterclockwise around the pin 61, the limiting part 62 is embedded in the limiting groove 33. The limiting groove 33 restricts the rotation angle of the limiting part 62, further restricting the rotation angle of the lower protrusion 6. At this time, the height of the highest point of the lower protrusion 6 is greater than the height of the upper side of the receiving drawer 3. During the process of pushing the receiving drawer 3 backward into the chamber 11, due to the interference between the lower protrusion 6 and the upper protrusion 52, the lower protrusion 6 will drive the upper protrusion 52 to move, thereby driving the sealing plate 5 to move. When the lower protrusion 6 is rotated clockwise around the pin 61, the lower protrusion 6 will be embedded in the notch 31, causing the limiting part 62 to flip upward. At this time, the height of the highest point of the lower protrusion 6 and the limiting part 62 is less than the height of the upper side of the receiving drawer 3. When the receiving drawer 3 is pushed back, since there is no interference with the upper protrusion 52, the sealing plate 5 will not be moved and the vertical hole 4 will not open.
[0028] Due to the varying consistency of greases, the above-mentioned feeding method can be successfully used for some thinner greases. However, it may be more difficult to feed thicker greases using the same method. Therefore, to further improve the feeding efficiency of greases, an assembly for squeezing the grease into the vertical hole 4 is provided. This assembly includes a drive motor 7, a lead screw 71, and a circular pressure plate 73. The end cap 21 is further fastened to the upper end of the storage tank 2. The output shaft of the drive motor 7 is positioned downwards at the center of the end cap 21, and the lead screw 71 is located inside the storage tank 2 and coaxially arranged with the storage tank 2. The lower end of the lead screw 71 is connected to the bottom wall of the storage tank 2 via a bearing, and the upper end is connected to the output shaft of the drive motor 7. A nut 72 is provided on the lead screw, and the circular pressure plate 73 is movably positioned on the outer ring of the nut 72 via a bearing. A limit rod 74 is provided on the side wall of the circular pressure plate 73, and a vertical groove 75 adapted to the limit rod 74 is provided on the inner wall of the storage tank 2 along its axial direction.
[0029] The drive motor 7 drives the lead screw 71 to rotate, causing the circular pressure plate 73 to move along the axis of the lead screw 71. When the circular pressure plate 73 approaches the bottom of the storage hopper 2, it achieves efficient material extraction by squeezing the lubricating grease.
[0030] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
