Description

Technical Field

[0001] The utility model relates to a fixing structure, in particular to a fixing structure for a dust cover of a bearing of a cartridge bottle production line, belonging to the technical field of bearings. Background Art

[0002] Borosilicate glass sleeves for pen-type syringes are commonly known as cartridges, which are used in genetic engineering, bioengineering, insulin and other fields. Cartridges are similar to syringes without a plunger, equivalent to "bottomless bottles". The front of the bottle is equipped with an injection needle protected by a rubber seal, the bottle mouth is sealed with a rubber stopper and an aluminum cap, and the tail is sealed with a rubber piston. During the production line processing of cartridges, bearings are required to effectively support rotating parts, reduce friction and wear, and improve the operating efficiency and stability of the production line. During the production process, bearings can ensure the precise positioning and smooth operation of mechanical equipment, thereby ensuring the production quality and production speed of the bottle. In addition, in order to prevent dust, pollutants and moisture from entering the bearing, thereby avoiding corrosion and wear of the bearing, a dust cover needs to be installed on the bearing surface.

[0003] Authorization announcement number (CN203685890U) discloses a bearing dust cover, the technical solution of which is as follows: it includes a dust cover body arranged in an annular shape, the thickness of the dust cover body is 2 mm to 3 mm, the inner circumferential surface of the dust cover body is provided with a curling edge, the outer circumferential surface of the dust cover body is provided with a mounting hole in the radial direction, a sphere is provided in the mounting hole, the opening of the mounting hole is used for holding the sphere, the sphere is freely rotatably arranged in the mounting hole and a part protrudes from the opening of the mounting hole, the other part is located in the mounting hole and is connected to the bottom wall of the mounting hole, and the mounting hole is filled with grease. The utility model not only makes the bearing dust cover and the outer ring of the bearing contact in the form of rolling friction, but also makes the bearing dust cover and the outer ring of the bearing in a lubricated state, reduces the friction resistance between the bearing dust cover and the outer ring of the bearing, and improves the performance of the bearing;

[0004] However, in the above-mentioned patented technology, the dust cover may lack a fixed structure. If the bearing dust cover lacks a fixed structure, it may cause the dust cover to fall off or move during the operation of the machine, thereby losing its original protective function. Dust, pollutants and moisture will have the opportunity to enter the bearing, causing damage to the bearing oil seal and contamination of the lubricating oil (or grease), increasing the risk of wear and corrosion, and ultimately causing the bearing to fail prematurely, reducing its service life, and increasing maintenance costs and downtime, affecting the stability and efficiency of the entire mechanical system.

[0005] Therefore, a fixing structure for a bearing dust cover of a cartridge bottle production line is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0028] By setting up the fixing mechanism 3, dust, dirt and other foreign matter can be effectively prevented from entering the interior of the bearing body, reducing wear and corrosion, thereby extending the service life of the bearing body 1. Secondly, it is beneficial to keep the lubricant inside the bearing body 1 from being contaminated, ensuring the lubrication effect, reducing maintenance frequency and cost, and also reducing the possibility of accidental loosening, thereby improving reliability and safety during use.

[0029] Example 2

[0030] In one embodiment, mounting bolts 4 are threadedly connected around the bottom of the base 301, and the upper ends of the mounting bolts 4 pass through the base 301 and extend to the top of the base 301. A slider 5 is fixedly connected to the bottom of the gear ring 304, and a slide groove 6 is provided at the top of the base 301. The slider 5 is slidably connected to the inner side of the slide groove 6. A guide groove 7 is provided on the inner side of the connecting sleeve 302. A guide block 8 is fixedly installed on the surface of the tooth plate 306, and the guide block 8 is slidably connected to the inner side of the guide groove 7.

[0031] By setting the mounting bolt 4, the base 301 can be connected to the dust cover body 2 to prevent the base 301 from falling off. By setting the slider 5 and the slide groove 6, the stability of the gear ring 304 during rotation can be improved. When the gear ring 304 is rotating, the slider 5 rotates along the inner cavity of the slide groove 6 to avoid deviation during rotation. The guide groove 7 and the guide block 8 can play a guiding role to prevent the tooth plate 306 from deviating during movement.

[0032] The utility model is in operation: when in use, after the dust cover body 2 is clamped on the surface of the bearing body 1, the base 301 is fixed to the bottom of the dust cover body 2 by installing the bolts 4. At this time, the gear ring 304 can be manually rotated to drive the gear 305 to rotate through the action of the tooth meshing. When the gear 305 rotates, it will drive the tooth plate 306 to move inward through the action of the tooth meshing. When the tooth plate 306 moves inward, it will drive the positioning block 307 to move inward. During the process of moving inward, the positioning block 307 will contact the surface of the dust cover body 2, thereby completing the fixation of the dust cover body 2 and preventing the dust cover body 2 from falling off.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
