Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mortars, in particular to a fixing and protecting device for a mortar. Background Technique
[0002] A mortar is one of the common experimental tools, equipped with a mortar pestle, and is often used to crush solid materials; during the use of the mortar, it needs to be pressed firmly and rotated at the same time. During the pressing and rotating process, the sample can be fully ground. In conventional biochemical molecule experiments, when extracting nucleic acids or proteins and other biological molecules, it is often necessary to maintain a low temperature to preserve their biological activity. At the same time, in order to increase tissue brittleness and facilitate grinding, liquid nitrogen is often added during the extraction and grinding process to maintain a low temperature.
[0003] The existing ceramic mortar has a large opening, the outer wall is not heat-insulating, the base is not fixed, and it needs to be pressed firmly by hand. Especially when grinding at low temperature for a long time, it freezes the hands. When adding liquid nitrogen for low-temperature grinding, the sample is easy to splash out with the liquid nitrogen, resulting in loss. The sample volume is small and the grinding is not sufficient. Therefore, it is necessary to continuously add liquid nitrogen to maintain a low temperature. Moreover, the mortar pestle is also easy to reduce the temperature after long-term contact with liquid nitrogen, and then the hand holding the mortar pestle is easy to be frostbitten. These problems have caused great troubles to the experimental operators. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a fixing and protecting device for a mortar. By setting a rubber base, anti-slip serrated protrusions, a transparent half-cover, a rubidium magnet, a rotating shaft, a shaft hole, a pestle hole, a mortar pestle and a rubber sleeve, when grinding tissues with liquid nitrogen, the base can be pressed by hand for grinding, avoiding long-term contact of the hand with the mortar added with liquid nitrogen, and preventing the hand from being frostbitten. Moreover, due to the anti-slip serrated protrusions on the bottom surface of the rubber base, the friction between the base and the table can be greatly increased, preventing the movement of the device during grinding, effectively avoiding the overturning of the mortar bowl, the spilling of liquid nitrogen and the loss of samples, greatly ensuring the safety of experimental operators and samples, and effectively solving the problems in the background technique.
[0005] To achieve the above object, the utility model provides the following technical solution: A fixing and protecting device for a mortar, including a rubber base, an anti-slip serrated protrusion is integrally formed on the lower side surface of the rubber base, a shaft hole is integrally formed on the upper part of the rubber base, a rotating shaft is inserted into the shaft hole, a transparent half-cover is installed on the outer side of the rotating shaft, rubidium magnets are installed on the opposite side surfaces of the transparent half-cover, a pestle hole is arranged at the center of the opposite side surfaces of the transparent half-cover, a mortar pestle is inserted into the pestle hole, and a rubber sleeve is sleeved on the outer side of the upper part of the mortar pestle.
[0006] Further, an anti-slip protrusion is integrally formed at the upper end of the mortar pestle, a mortar bowl is arranged inside the rubber base, and an anti-slip handle is integrally formed on the upper edge of the mortar bowl.
[0007] Further, the rubber sleeve is connected to the pestle through perforation, and the sides of the two transparent half - covers are connected by the rubidium magnet, and the rubidium magnet is adhesively bonded to the transparent half - cover.
[0008] Further, the two transparent half - covers are connected to the shaft holes on the rubber base through the rotating shaft, and the rotating shaft is rotatably connected to the shaft holes.
[0009] Further, a bowl - bottom protrusion is integrally formed on the inner bottom side of the rubber base, and a protrusion groove is integrally formed on the lower side of the pestle bowl.
[0010] Further, anti - slip ribs are formed on the anti - slip pinch handle.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. Through the rubber base, anti - slip saw - tooth protrusions, transparent half - covers, rubidium magnets, rotating shafts, shaft holes, hammer holes, pestles and rubber sleeves provided in the utility model, when performing tissue liquid - nitrogen grinding, one can hold the base by hand for grinding, avoiding long - term contact of the hand with the pestle filled with liquid nitrogen, thus preventing the hand from being frostbitten. Moreover, due to the anti - slip saw - tooth protrusions on the bottom surface of the rubber base, the friction between the base and the table can be greatly increased, preventing the movement of the device during grinding, effectively avoiding the overturning of the pestle bowl, the spilling of liquid nitrogen and the loss of samples, and greatly ensuring the safety of experimental operators and samples.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-3 , this embodiment provides a technical solution: a mortar fixing and protecting device, including a rubber base 1, an anti-slip serrated protrusion 7 is integrally formed on the lower side of the rubber base 1, a shaft hole 2 is integrally formed on the upper part of the rubber base 1, a rotating shaft 8 is inserted into the shaft hole 2, a transparent half cover 3 is installed outside the rotating shaft 8, a rubidium magnet 11 is installed on the opposite sides of the transparent half cover 3, a hammer hole 12 is provided at the center of the opposite sides of the transparent half cover 3, a mortar hammer 4 is inserted into the hammer hole 12, and a rubber sleeve 5 is sleeved outside the upper part of the mortar hammer 4.
[0020] As Figures 1-3 shown, the rubber sleeve 5 can perform anti-slip and anti-freezing treatments on the mortar hammer 4, so that when the user holds the mortar hammer 4, hand slipping can be avoided, and the low-temperature mortar hammer 4 can also be prevented from freezing the user's hand. The rubidium magnet 11 can make the two transparent half covers 3 adsorb together, so that the transparent half cover 3 can limit the mortar hammer 4 through the hammer hole 12, reducing the overflow of liquid nitrogen from the mortar bowl 9. After the mortar bowl 9 is placed in the rubber base 1, the anti-slip serrated protrusion 7 can make the mortar bowl 9 and the rubber base 1 stably placed on the experimental table, avoiding the sliding of the rubber base 1 and ensuring the stability of the grinding process.
[0021] An anti-slip protrusion 6 is integrally formed at the upper end of the mortar hammer 4, a mortar bowl 9 is arranged inside the rubber base 1, and an anti-slip pinch handle 10 is integrally formed on the upper edge of the mortar bowl 9.
[0022] As Figures 1-2 shown, the sample material to be ground can be placed in the mortar bowl 9. The anti-slip protrusion 6 can prevent the user's hand from slipping off when using the mortar hammer 4, and the anti-slip pinch handle 10 can facilitate the user to take or place the mortar bowl 9 into the rubber base 1.
[0023] The rubber sleeve 5 is connected to the mortar hammer 4 in a penetrating manner, and the two sides of the transparent half covers 3 are connected by a rubidium magnet 11, and the rubidium magnet 11 is glued to the transparent half cover 3.
[0024] As Figure 1 and 3 shown, the rubidium magnet 11 can adsorb and fix the two transparent half covers 3 together, and then make the two transparent half covers 3 fit together, so that after the mortar hammer 4 passes through the hammer hole 12, the sample inside the mortar bowl 9 can be ground.
[0025] Two transparent half - covers 3 are connected to the shaft holes 2 on the rubber base 1 through a rotating shaft 8, and the rotating shaft 8 is rotatably connected to the shaft holes 2.
[0026] As Figures 1-3 shown, the rotating shaft 8 can make the two transparent half - covers 3 rotate to open and close, so that the transparent half - covers 3 can cover the upper side of the mortar bowl 9, avoiding the splashing of samples and liquid nitrogen.
[0027] A bowl - bottom protrusion is integrally formed on the inner bottom side of the rubber base 1, and a protruding groove is integrally formed on the lower side surface of the mortar bowl 9.
[0028] Anti - slip ribs are formed on the anti - slip pinch handle 10. The setting of the anti - slip ribs facilitates the user to take out the mortar hammer 4.
[0029] The working principle of the mortar fixing and protecting device provided by the present utility model is as follows: As Figures 1-3 shown, during use, the mortar bowl 9 is placed inside the rubber base 1, then the sample to be ground and liquid nitrogen are added into the mortar bowl 9, and the transparent half - covers 3 are rotated and covered on the rubber base 1. The rubidium magnet 11 can adsorb and fix the two transparent half - covers 3 together, so that the transparent half - covers 3 cover the upper side of the rubber base 1. Then the mortar hammer 4 is inserted into the mortar bowl 9 through the hammer hole 12. One hand holds the rubber base 1, and the other hand holds the rubber sleeve 5 on the mortar hammer 4 to grind the sample, so that the sample is effectively ground. The setting of the transparent half - covers 3 can reduce the leakage amount of liquid nitrogen from the mortar bowl 9. The rubber base 1 can provide heat insulation protection for the mortar bowl 9, avoiding the low temperature in the mortar bowl 9 from hurting the hands of the experimenter. After grinding is completed, the transparent half - covers 3 are opened, and then the mortar bowl 9 can be taken out from the rubber base 1 through the anti - slip pinch handle 10.
[0030] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
