Description

Technical Field

[0001] The utility model relates to the field of liquid transfer guns, in particular to a reminder nameplate for liquid transfer guns. Background Art

[0002] A pipette is a device used in laboratory work, a tool for accurately sucking and releasing micro-amounts of liquid. It is commonly used in analytical chemistry, biochemistry, cell culture, and some other laboratory work to perform precise pipetting operations.

[0003] After using a pipette, it is usually necessary to adjust the capacity display of the pipette to the maximum scale. However, in actual operation, the operator may forget to adjust the pipette to the maximum scale after using the pipette, and it is difficult for existing pipettes to remind the operator. Therefore, we propose a reminder nameplate for the pipette. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a reminder nameplate for a pipette, by setting a reminder nameplate body, which can be made of materials such as metal, plastic or stickers, and can be connected to the surface of the shell by welding, screw connection or pasting. The reminder words set on the outside of the reminder nameplate body can be set to words such as "Please adjust to zero after use", so as to remind the operator to adjust the range to the maximum range when not in use or after using the pipette, so as to facilitate the normal use of the pipette next time.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A reminder nameplate for a liquid transfer gun comprises a liquid transfer gun body. The outside of the liquid transfer gun body is connected to a reminder nameplate body, and the outside of the reminder nameplate body is provided with reminder words.

[0007] By setting a reminder nameplate body, the reminder nameplate body can be made of materials such as metal, plastic or sticker, and can be connected to the surface of the shell by welding, screw connection or pasting. The reminder words set on the outside of the reminder nameplate body can be set to words such as "Please adjust to zero after use", so as to remind the operator to adjust the range to the maximum range when not in use or after using the pipette, so as to facilitate the normal use of the pipette next time.

[0008] Furthermore, the pipette gun body includes a shell, and the shell is connected to the prompt nameplate body.

[0009] Since the shell needs to be held with the palm of the hand when using the pipette, the prompt nameplate body needs to be set in the part of the shell that is not blocked by the palm, and the thickness should be reduced as much as possible to avoid discomfort when the fingers touch the edge of the prompt nameplate body.

[0010] Furthermore, the upper end of the shell is movably connected to a pressing column, and the upper end of the pressing column is rotatably connected to a volume adjustment knob.

[0011] Furthermore, the upper end of the shell is located on the right side of the pressing column and is movably connected to a tip detachment button, and a capacity display window is provided on the outside of the shell.

[0012] Furthermore, the lower end of the shell is movably connected to a sleeve, and the lower end of the sleeve is nested and connected to a suction head tube.

[0013] Furthermore, the reminder nameplate body has a certain curvature, and the reminder nameplate body is adapted to the housing.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. By setting a reminder nameplate body, the reminder nameplate body can be made of materials such as metal, plastic or stickers, and can be connected to the surface of the shell by welding, screw connection or pasting. The reminder words set on the outside of the reminder nameplate body can be set to "Please adjust to zero after use" and other words, so as to remind the operator to adjust the range to the maximum range when not in use or after using the pipette, so as to facilitate the normal use of the pipette next time;

[0016] 2. Since the pipette needs to be held with the palm of the hand when using it, the prompt nameplate body needs to be set in the part of the shell that is not blocked by the palm, and the thickness should be reduced as much as possible to avoid discomfort when the fingers touch the edge of the prompt nameplate body.
