Description

Technical Field

[0001] The utility model relates to the field of inoculating rings, in particular to a sterilized inoculating ring. Background Art

[0002] An inoculating loop is a commonly used tool for bacterial culture and is widely used in a variety of disciplines, including microbiology testing, cell microbiology, and molecular biology. Inoculating loops are generally divided into disposable plastic inoculating loops (made of plastic) and metal inoculating loops (steel, platinum, or nickel-chromium alloy).

[0003] In the prior art, metal inoculation loops need to be sterilized before use, and are often sterilized by high-temperature heating.

[0004] However, the existing inoculation loop needs to be held in hand during heating, which is rather cumbersome. Moreover, after sterilization, the inoculation loop cannot be used directly because the temperature is too high and needs to be cooled for a long time, which greatly affects the efficiency of use.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] See also Figures 1 to 6 , the utility model provides a technical solution:

[0029] Example 1: The sterile inoculation ring includes a handle 1, and a metal rod 2 is fixedly connected to the upper middle part of the handle 1; an inoculation ring 3, which is installed above the metal rod 2 and is detachably connected to the metal rod 2; a cooling sleeve 4, which is sleeved on the outside of the inoculation ring 3; a charging base 5, which is set on a desktop or table, and the upper middle part of the charging base 5 is plugged into the bottom of the handle 1, and the two are electrically connected; a positioning frame 6, which is set above the charging base 5 and is fixed to the handle 1.

[0030] Example 2: Based on Example 1, in order to make the inoculation ring 3 detachable and to cool the inoculation ring 3 and isolate bacteria when it is not in use, a notch is provided at the upper middle part of the metal rod 2, and a number of evenly distributed splines 22 are fixedly connected to the inner wall of the notch. A positioning rod 31 is vertically inserted into the notch, and a spline groove is provided on the bottom outer wall of the positioning rod 31. The spline 22 is plugged into the spline groove, and the upper end of the positioning rod 31 is fixedly connected to the inoculation ring 3. A number of threaded petals 21 are fixedly connected to the upper outer wall of the top outer side of the metal rod 2. The threaded petals 21 are arranged in a truncated cone shape. The inner wall of the threaded petal 21 is clamped and connected to the outer wall of the positioning rod 31. A nut 23 is provided on the outer sleeve of the threaded petal 21 and is screwed to the inner wall of the nut 23. An aperture is provided in the middle of the nut 23 for the positioning rod 31 to pass through. The inoculation ring 3 and the positioning rod 31 that are exposed from the metal rod 2 are covered with a cooling sleeve 4. The cooling sleeve 4 is a cavity structure with an opening at the bottom. A heat-absorbing rubber pad 41 is provided on the inner wall of the cooling sleeve 4, and the heat-absorbing rubber pad 41 is filled with sterilizing glue.

[0031] The nut 23 is rotated counterclockwise so that the nut 23 rotates upward until the nut 23 is removed from the threaded petal 21, so that the threaded petal 21 loosens the positioning rod 31, and the positioning rod 31 and the inoculation ring 3 can be pulled out from the metal rod 2, which is convenient for the replacement of the inoculation ring 3. When the inoculation ring 3 is used for the second time, the inoculation ring 3 can be directly replaced. After the positioning rod 31 is inserted into the slot along the spline 22, the nut 23 is tightened so that the threaded petal 21 is retracted inward, clamping and fixing the positioning rod 31, thereby completing the fixed installation of the inoculation ring 3. When the inoculation ring 3 is not in use, the cooling sleeve 4 is put on the inoculation ring 3 and the part of the positioning rod 31 exposed outside the metal rod 2. The heat-absorbing rubber pad 41 in the through-hole cooling sleeve 4 cools the inoculation ring 3 and the positioning rod 31, and sterilizes the inoculation ring 3 by filling in the sterilizing glue, thereby preventing external bacteria from contaminating the inoculation ring 3 and the positioning rod 31.

[0032] Example 3: On the basis of Example 2, in order to facilitate the heating of the positioning rod 31 and the inoculation ring 3, and to charge the heating component, and to prevent the handle 1 from shaking or falling during the charging process, which would lead to the problem of invalid charging, the bottom of the handle 1 is vertically inserted into the upper middle part of the charging seat 5. The handle 1 is provided with a heating component and a power storage structure. A fixed seat 51 is fixedly connected to the upper rear side of the charging seat 5, and a lifting seat 52 is vertically slidably connected to the upper part of the fixed seat 51. The upper middle part of the fixed seat 51 and the lower middle part of the lifting seat 52 are respectively fixedly connected to the upper and lower ends of the first spring 53. The upper parts of both sides of the fixed seat 51 are fixedly connected to the lower part of the fixed end of the telescopic rod 54. The movable end of the telescopic rod 54 is fixedly connected to the lower part of the lifting seat 52. The outer walls on both sides of the rear side of the lifting seat 52 are respectively fixedly connected to brackets 55. A U-shaped positioning frame 6 is fixedly connected to the front side of the lifting seat 52. Two horizontal sliding connections are connected to the positioning frame 6. The inner ends of the insertion rods 61 are inserted into the slots on both sides below the handle 1. The outer ends of the insertion rods 61 are fixedly connected to the inner ends of the second spring 62, and the outer ends of the second spring 62 are fixedly connected to the inner wall of the positioning frame 6. The middle portion of the outer side of the insertion rod 61 is fixedly connected to the two ends of the pull rope 63. The middle portion of the pull rope 63 passes through the positioning frames 6 on both sides and is coiled around the rear of the lifting seat 52. The positioning frame 6 passes through the middle of the two side brackets 55. The pull rope 63 is a non-elastic rope.

[0033] The handle 1 is pushed into the middle of the positioning frame 6 so that the handle 1 squeezes the insertion rod 61 outward, causing the insertion rod 61 to shrink into the positioning frame 6. After the rear side of the handle 1 is against the rear inner wall of the positioning frame 6, the slots on both sides of the handle 1 are horizontally aligned with the insertion rod 61. Under the elastic force of the second spring 62, the insertion rod 61 is inserted into the slot, and the handle 1 is plugged and fixed. The handle 1 is released. Under the elastic force of the first spring 53, the upgrade seat 52 drives the positioning frame 6 to slide vertically downward, causing the handle 1 to slide vertically downward and tightly against the upper middle inner wall of the charging seat 5, ensuring that the electrical connection between the handle 1 and the charging seat 5 is not easy to loosen, preventing the handle 1 from being unable to loosen from the electrical sensing part of the charging seat 5, causing the problem of invalid charging. When the handle 1 needs to be taken out, the pull rope 63 is pulled backward so that the pull rope 63 drives the insertion block 61 to shrink, and the handle 1 is directly pulled out vertically upward so that the bottom of the handle 1 is moved out of the charging seat 5.
