Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bottle opener. Background Technology

[0002] Ampoules are widely used in the medical and laboratory fields for containing various injectable solutions and chemical reagents due to their excellent sealing and stability. However, the traditional method of opening ampoules is to break the neck by hand, which poses many safety hazards.

[0003] On the one hand, during the breaking process, sharp glass shards are easily generated, which may not only cut the skin of medical staff or laboratory personnel, but may also mix into the medicine, causing pollution and affecting the safety of medication and the accuracy of experimental results.

[0004] On the other hand, when breaking it by hand, uneven force may cause the ampoule to shatter, spilling the medicine inside and resulting in medicine waste and environmental pollution.

[0005] Although some existing bottle openers use cutting methods, they have problems such as complex structure, inconvenient operation, and high cost. For example, in order to adapt to ampoules of different sizes, multiple sets of adjusting bolts and complex linkage structures are needed to adjust the position and angle of the grinding wheel. The number of parts is large and the assembly process is complicated, which increases production and maintenance costs. Utility Model Content

[0006] The purpose of this invention is to provide a bottle opener to solve the above-mentioned problems, as detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The present invention provides a bottle opener, including an upper handle and a lower handle. The upper handle is hinged to the lower handle by a pin. An upper clamping head and a lower clamping head are respectively fixedly connected to the same end of the upper handle and the lower handle.

[0009] The lower jaw is rotatably connected to two rubber rollers on the side corresponding to the upper jaw, and a grinding wheel is fixedly connected to the side of the upper jaw corresponding to the rubber rollers.

[0010] Using the above-mentioned bottle opener, operate the upper and lower handles to clamp the upper and lower clamps at the neck of the ampoule, then rotate the upper clamp to drive the grinding wheel to rotate around the neck, and finally operate the upper and lower clamps to easily break off the bottle neck.

[0011] Preferably, a second rubber roller is rotatably connected to one side of the upper clamp head corresponding to the first rubber roller.

[0012] Preferably, the second rubber roller corresponds to the midpoint of the two first rubber rollers.

[0013] Preferably, the second rubber roller is located on top of the grinding wheel.

[0014] Preferably, the distance between the two edges of the rubber roller and the inner side of the upper pliers head is less than the distance between the edge of the grinding wheel and the inner side of the upper pliers head.

[0015] Preferably, rubber sleeves are fixedly connected to both the upper and lower handles.

[0016] Preferably, the inner side of the lower jaw is provided with an arc surface, and two rubber rollers are symmetrically connected to the arc surface, rotating about the lowest point of the arc surface along the length of the lower jaw.

[0017] Preferably, the bottom of the upper clamp head is fixedly connected to a connecting seat, and the connecting seat has an installation groove, in which the grinding wheel is fixedly connected.

[0018] Preferably, the portion of the grinding wheel installed in the mounting groove is triangular, and the portion of the grinding wheel outside the mounting groove is arc-shaped.

[0019] Preferably, the grinding wheel is fixedly connected to the mounting groove by adhesive.

[0020] The beneficial effects are:

[0021] The upper and lower jaws work together to grip the neck of the ampoule. By rotating the upper jaw, the grinding wheel is driven to rotate around the neck. Finally, the bottle neck can be easily broken off by using the upper and lower jaws. The structure is simple, the operation is labor-saving, and it prevents hand injuries.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-4 As shown, this utility model provides a bottle opener, including an upper handle 1 and a lower handle 2. The upper handle 1 is hinged to the lower handle 2 by a pin 5. An upper clamping head 3 and a lower clamping head 4 are respectively fixedly connected to the same end of the upper handle 1 and the lower handle 2.

[0031] The lower jaw 4 is rotatably connected to two rubber rollers 7 on one side corresponding to the upper jaw 3, and the upper jaw 3 is fixedly connected to a grinding wheel 9 on one side corresponding to the rubber rollers 7.

[0032] As an optional implementation, a second rubber roller 8 is rotatably connected to one side of the upper jaw 3 corresponding to the first rubber roller 7. The second rubber roller 8 cooperates with the two first rubber rollers 7 to reduce the friction between the upper jaw 3 and the lower jaw 4 and the ampoule, and also has a guiding function to make the upper jaw 3 and the lower jaw 4 rotate stably.

[0033] The midpoints of rubber roller 28 and the two rubber rollers 17 correspond to each other. This positioning can improve the stability of the rubber rollers 28 and 17 in holding the bottle head.

[0034] Rubber roller 28 is located on top of grinding wheel 9. The position of grinding wheel 9 corresponds to the bottleneck. Therefore, rubber roller 28 should be misaligned with the bottleneck.

[0035] The distance between the edge of the rubber roller 8 and the inner side of the upper clamp head 3 is less than the distance between the edge of the grinding wheel 9 and the inner side of the upper clamp head 3. This design can improve the adaptability to ampoules, with the narrowest part of the ampoule as the bottleneck, and gradually thickening above the bottleneck.

[0036] Rubber sleeves 6 are fixedly connected to both the upper handle 1 and the lower handle 2.

[0037] The lower jaw 4 has an arc surface 10 on its inner side. Two rubber rollers 7 are symmetrically connected to the arc surface 10, rotating around the lowest point of the arc surface 10 along the length of the lower jaw 4. This design can improve the adaptability to larger ampoules.

[0038] The bottom of the upper pliers head 3 is fixedly connected to a connecting seat 11, and the connecting seat 11 has an installation groove, in which the grinding wheel 9 is fixedly connected.

[0039] The part of the grinding wheel 9 that is installed in the mounting groove is triangular, and the part of the grinding wheel 9 that is outside the mounting groove is arc-shaped. This design can improve the firmness of the fixed installation of the grinding wheel 9.

[0040] The grinding wheel 9 is fixedly connected to the mounting groove with glue, which can be done by glue or screws.

[0041] Using the above structure, operate the upper handle 1 and the lower handle 2 to clamp the neck of the ampoule with the upper clamp head 3 and the lower clamp head 4. Then rotate the upper clamp head 3 to drive the grinding wheel 9 to rotate around the neck. Finally, operate the upper clamp head 3 and the lower clamp head 4 to easily break off the bottle neck.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
