Technical Field

[0001] This utility model relates to the technical field of bottle openers, and in particular to a bottle opener with an easy-to-change grinding wheel. Background Technology

[0002] Healthcare workers prepare a large number of intravenous medications daily, requiring the opening of numerous ampoules and vials. When preparing medications, forceps or scissors are typically used to open the ampoule caps, or a grinding wheel is used to make a circumferential cut and then the cap is broken by hand. The hospital's intravenous preparation center centrally prepares medications, handling large daily volumes, resulting in frequent use of ampoule openers and frequent replacement of grinding wheels.

[0003] The existing device uses a grinding wheel fixed inside the bottle opener with bolts and nuts, requiring a screwdriver for removal during replacement, which is inconvenient. Therefore, a new fixing structure for easy grinding wheel replacement was designed to address this issue. Utility Model Content

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Given the current technology, hospital intravenous fluid preparation centers centrally prepare large quantities of medication daily, resulting in frequent use of bottle openers and frequent replacement of grinding wheels. In existing devices, the grinding wheel is fixed inside the bottle opener with bolts and nuts, requiring a screwdriver for removal during replacement, making the operation rather inconvenient.

[0026] When it is necessary to disassemble the grinding wheel 13, the protrusion 28 can be pinched and slid upward inside the through groove 27, while the plate 24 moves inside the housing 22, causing the spring 23 to be squeezed. At the same time, the upright 25 and the insert rod 26 are disengaged from the inside of the grinding wheel 13 and the inside of the positioning hole 21, thus disengaging the fixing of the grinding wheel 13. Finally, a new grinding wheel 13 is inserted into the groove 12, the protrusion 28 is released, the spring 23 rebounds and pushes the plate 24 downward, so that the upright 25 and the insert rod 26 are in contact with the top of the grinding wheel 13. Then the grinding wheel 13 is rotated, and after the insert rod 26 is aligned with the positioning hole 21, the upright 25 and the insert rod 26 are inserted into the inside of the grinding wheel 13 and the inside of the positioning hole 21 respectively to complete the installation of the grinding wheel 13.

[0027] As shown in the attached figure, this embodiment of the invention provides a bottle opener that facilitates the replacement of the grinding wheel.

[0028] The device includes: a groove 12 on one side of a bottle opener body 11; a grinding wheel 13 disposed inside the groove 12; a fixing component 2 on the top of the bottle opener body 11, the fixing component 2 including: a positioning hole 21 on the top of the grinding wheel 13; a housing 22 fixedly disposed on the top of the bottle opener body 11; a spring 23 disposed inside the housing 22, with its top end fixedly connected to the inner side wall of the housing 22; a plate 24 slidably disposed inside the spring 23 and connected to the bottom end of the spring 23; a vertical rod 25 fixedly disposed at the bottom end of the plate 24, penetrating the bottle opener body 11 and inserted into the interior of the grinding wheel 13; an insertion rod 26 fixedly disposed at the bottom end of the plate 24, with its bottom end penetrating the bottle opener body 11 and inserted into the positioning hole 21; a through groove 27 on the outer side wall of the housing 22; and a protrusion 28 with one end inserted into the through groove 27 and fixedly connected to the plate 24.

[0029] When disassembling the grinding wheel 13, pinch the protrusion 28 and slide it upward inside the through groove 27. At the same time, move the plate 24 inside the housing 22, causing the spring 23 to be compressed. This causes the upright 25 and the insert rod 26 to disengage from the inside of the grinding wheel 13 and the inside of the positioning hole 21, thus securing the grinding wheel 13. Finally, replace the grinding wheel 13 and insert it into the groove 12. Release the protrusion 28, and the spring 23 will rebound, pushing the plate 24 downward so that the upright 25 and the insert rod 26 are in contact with the top of the grinding wheel 13. Then rotate the grinding wheel 13. After the insert rod 26 is aligned with the positioning hole 21, insert the upright 25 and the insert rod 26 into the inside of the grinding wheel 13 and the positioning hole 21 respectively to complete the installation of the grinding wheel 13.

[0030] In some embodiments, the bottom end of the upright 25 is designed with a slope.

[0031] The beveled design allows the grinding wheel 13 to be directly inserted into the inside of the groove 12. When the upright 25 is squeezed, it will move upward and retract into the inside of the housing 22 until it is aligned with the inside of the grinding wheel 13. Then the spring 23 will rebound and push the upright 25 into the inside of the grinding wheel 13. The insertion rod 26 is inserted into the positioning hole 21 to prevent the grinding wheel 13 from rotating.

[0032] In some embodiments, the outer wall of the grinding wheel 13 is in contact with the inner wall of the groove 12.

[0033] The fitting design allows the inner side of the grinding wheel 13 to be better aligned with the upright 25 after it is inserted into the groove 12.

[0034] In some embodiments, the fixing component 2 further includes a sponge block 281 fixedly disposed at one end of the protrusion 28.

[0035] The design of the sponge block 281 allows for increased comfort by utilizing the softness of the sponge when it is pinched against the protrusion 28.

[0036] In some embodiments, the fixing component 2 further includes a cone 29 fixedly disposed at the bottom of the insertion rod 26.

[0037] The design of the tip of the cone 29 makes it relatively easier to insert into the positioning hole 21.

[0038] In some embodiments, a clamping assembly 3 is provided at the bottom of the bottle opener body 11. The clamping assembly 3 includes: a threaded rod 31 with its top end inserted into the interior of the bottle opener body 11 and threadedly connected to the bottle opener body 11; and a top plate 32 rotatably disposed on the top of the threaded rod 31.

[0039] When the thickness of the grinding wheel 13 is less than the internal width of the groove 12, the threaded rod 31 can be rotated to insert it into the inside of the groove 12, so that the top plate 32 can move upward to clamp the grinding wheel 13.

[0040] In some embodiments, the clamping assembly 3 further includes a knob 33 fixedly disposed at the bottom of the threaded rod 31.

[0041] The knob 33 is designed for easy gripping, and the grooves on the surface of the knob 33 can increase friction when rotating.

[0042] In some embodiments, the clamping assembly 3 further includes a rubber pad 34 fixedly disposed on the top of the top plate 32.

[0043] The design of the rubber pad 34 can better protect the grinding wheel 13. At the same time, the rubber material has greater friction with the grinding wheel 13, which can better ensure the stability of the grinding wheel 13.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
