Abstract
The utility model relates to a multi-joint coating rod for biological teaching. The multi-joint coating rod comprises a handheld part, joints and a coating functional area which are sequentially connected, wherein a balance area is arranged between the handheld part and the joints, and the handheld part is a steel metal rod which is provided with a thread; the balance area is formed by a transparent glass tube, wherein a colorful flowable liquid is packaged, the balance area is horizontally fixed on the handheld part, a transparent glass tube in the balance area is vertical to the handheld part, the joints are movably connected with the coating functional area, and the coating functional area comprises linear coating functional areas which are different in size and specification. When the rod is used, the coating functional areas in proper shape and size can be connected to the joints of the coating rod according to demand for coating operation. The handheld part is not easy to break, the thread is beneficial for preventing slip, and the coating functional areas can be replaced. A circular coating functional area used can coat without a dead angle. The coating rod is convenient to use, simple in integral structure, good in stability and high in reliability.
Description
Technical field
The utility model relates to a kind of biological subject spreading rod, relates in particular to a kind of bioconversion medium polylinker spreading rod.
Background technology
In bioconversion medium process, the linear glass spreading rod of ordinary straight is easy to break, and often broke the Handheld Division of spreading rod, and in heating on spirit lamp, linear applying area is easy to be hardening cracked, heating and cooling repeatedly, and spreading rod is easy to burst.Dangerously be not durable yet.Culture dish has different size, and the spreading rod that have plurality of specifications just can carry out work.Common spreading rod is difficult to comprehensive covering in coating process.The unskilled student of coating operation, spreading rod is difficult to level and grips, cause crawling with.
Utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of a kind of bioconversion medium polylinker spreading rod simple in structure, easy to use, safe and reliable is provided, the carrying out coating operation that it can help biology worker.A kind of bioconversion medium polylinker spreading rod described in the utility model, includes Handheld Division, equilibrium area, joint and coating function district.Handheld Division, joint, coating function district connects successively.Equilibrium area is arranged between Handheld Division and joint.Handheld Division is a steel metallic rod, above steel metallic rod, has screw thread, can play anti-skidding effect.Equilibrium area is made up of a transparent glass tube, and inside is packaged with appropriate coloured flowable liquids, and uniform liquid is distributed in and in transparent glass tube, represents balance working order.Equilibrium area is horizontally fixed on Handheld Division, and transparent glass tube and the Handheld Division of equilibrium area are perpendicular.Joint is flexibly connected with coating function district.Coating function district includes the linear coating function district of different size specifications, also include circular coating function district, and circular coating function district is set to different size specifications.When use, can as required, suitable shape and big or small coating function district be connected on the joint of spreading rod, be coated with operation.
Compared with prior art, the beneficial effects of the utility model are: Handheld Division is metal, are not easy to fracture, screw thread contributes to anti-skidding, and operation that also can be stable when hand is perspired, because coating function district is to be flexibly connected with the joint of spreading rod, coating function district has damaged, and can change easily.Owing to can using circular coating function district, can be without the carrying out coating operation at dead angle.The suitable shape that only need to prepare some amount and big or small coating function district can meet Bu Tong big or small culture dish with spreading rod is for subsequent use, and do not need a lot of spreading rods of preparation, when sterilizing, workload has also reduced, and be not easy to dye miscellaneous bacteria, easy to use, one-piece construction is simple, good stability, and reliability is high.
Brief description of the drawings
Embodiment
Referring now to accompanying drawing 1, be described as follows: a kind of bioconversion medium polylinker spreading rod, includes Handheld Division 1, equilibrium area 2, joint 3 and coating function district 4 in conjunction with the embodiments.Handheld Division 1, joint 3, coating function district 4 connects successively.Equilibrium area 2 is arranged between Handheld Division 1 and joint 3.Handheld Division 1 is a steel metallic rod, above steel metallic rod, has screw thread, can play anti-skidding effect.Equilibrium area 2 is made up of a transparent glass tube, and inside is packaged with appropriate coloured flowable liquids, and uniform liquid is distributed in and in transparent glass tube, represents balance working order.Equilibrium area 2 is horizontally fixed on Handheld Division 1, and the transparent glass tube of equilibrium area 2 and Handheld Division 1 are perpendicular.Joint 3 is flexibly connected with coating function district 4.Coating function district 4 includes the linear coating function district 4 of different size specifications, also include circular coating function district 4, and circular coating function district 4 is set to different size specifications.When use, can as required, suitable shape and big or small coating function district 4 be connected on the joint 3 of spreading rod, be coated with operation.Compared with prior art, the beneficial effects of the utility model are: Handheld Division 1 is metal, is not easy to fracture, screw thread contributes to anti-skidding, prevents from when hand from perspiring operating inconvenience, because coating function district 4 is to be flexibly connected with the joint 3 of spreading rod, coating function district 4 has damaged, and can change easily.Owing to can using circular coating function district 4, can be without the carrying out coating operation at dead angle.In experiment time, only need to be prepared suitable shape and big or small coating function district 4 and can be met Bu Tong big or small culture dish with spreading rod is for subsequent use, and do not need a lot of spreading rods of preparation, when sterilizing, workload has also reduced, and be not easy to dye miscellaneous bacteria, easy to use, one-piece construction is simple, good stability, and reliability is high.
