Abstract
The utility model discloses a kind of inoculating needle for Microbiology Experiment, comprise handle, connecting rod and needle body, described handle and connecting rod are integral type structure, and one end of needle body is fixedly connected with connecting rod by the dop that is arranged on connecting rod bottom, is provided with the barb of indent on the top of described handle.Inoculating needle of the present utility model, adopts the material of high temperature high voltage resistant to make, and is convenient to sterilising treatment; Inoculating needle can be hung on the horizontal line that fine rule or iron wire class be barricaded as by the barb on handle, avoided idle inoculating needle and the touching of other implements after syringe needle bend or rupture; The design of dop can be changed the needle body having worn and torn quickly and easily, increases work efficiency.
Description
Technical field
The utility model belongs to experiment equipment technical field, is specifically related to a kind of inoculating needle for Microbiology Experiment.
Background technology
Because inoculating needle frequency of utilization is higher, be often placed on the table top of Bechtop.Because the working space of Bechtop is limited, while carrying out other tests therein, often can be because cause syringe needle flexural deformation or the fracture of idle inoculating needle with the collision of other implements, the normal progress of impact test; In addition, the needle body of inoculating needle is with needing after a period of time replacing, and current existing inoculating needle on the market will be realized the replacing of needle body, need first the nut of fixing needle body to be turned on, extract after the needle body of wearing and tearing, new needle body is inserted to the little pin hole on connecting rod, then the nut of screwing on.In this process, turn the process complexity of nut, waste time and energy, be unfavorable for improving test efficiency; in addition,, because the bore of pin hole is a bit larger tham the external diameter of needle body, be difficult for needle body to insert; and often can make new needle body root bending, can not successfully replace needle body, what impact was tested carries out smoothly.
Utility model content
The technical problems to be solved in the utility model: after idle inoculating needle and the touching of other implements, syringe needle easily bends or ruptures; In the time changing the needle body of inoculating needle, process is loaded down with trivial details, wastes time and energy, and impact experiment is carried out.
The technical solution of the utility model is such realization: a kind of inoculating needle for Microbiology Experiment, comprise handle, connecting rod and needle body, described handle and connecting rod are integral type structure, one end of needle body is fixedly connected with connecting rod by the dop that is arranged on connecting rod bottom, is provided with the barb of indent on the top of described handle.
Preferably, described dop is made up of round table-like snap ring and tongue, and described snap ring and tongue are from top to bottom sleeved on described connecting rod successively, and when fixing needle body, snap ring is connected to tongue upper end.
Preferably, described tongue comprises three gates.
Preferably, the syringe needle of described needle body is circular.
Preferably, the minimum diameter of snap ring is greater than the minimum diameter of tongue, is less than the maximum inner diameter of tongue.
The beneficial effects of the utility model: inoculating needle of the present utility model, handle adopts the polythene material of high temperature high voltage resistant and poor heat conductivity to make, and connecting rod is made up of the stainless steel of high temperature high voltage resistant, and needle body is that the platinum wire that toughness is stronger is made, and is convenient to sterilising treatment; Barb on handle can hang over inoculating needle on the horizontal line that fine rule or iron wire class be barricaded as, avoided idle inoculating needle and the touching of other implements after syringe needle bend or rupture; The design of dop can be changed the needle body having worn and torn quickly and easily, increases work efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model inoculating needle;
Fig. 2 is the structural representation of a kind of embodiment of dop of the utility model inoculating needle;
Fig. 3 is the upward view of Fig. 2;
In figure: 1 handle, 2 connecting rods, 3 needle bodies, 4 barbs, 5 dops, 6 snap rings, 7 tongues, 8 gates.
Embodiment
The embodiment by reference to the accompanying drawings the utility model being provided is described in further detail:
As Figure 1-3, a kind of inoculating needle for Microbiology Experiment that the utility model relates to, comprise handle 1, connecting rod 2 and needle body 3, described handle 1 and connecting rod 2 are integral type structure, one end of needle body 3 is fixedly connected with connecting rod 2 by the dop 5 that is arranged on connecting rod 2 bottoms, be provided with the barb 4 of indent on the top of described handle 1, handle 1, connecting rod 2 and needle body 3 are all selected high-temperature-resistant high-pressure-resistant material.
As further improvement of the utility model, described dop 5 is made up of round table-like snap ring 6 and tongue 7, and described snap ring 6 and tongue 7 are from top to bottom sleeved on described connecting rod 2 successively, and when fixing needle body 3, snap ring 6 is connected to tongue 7 upper ends.
As further improvement of the utility model, described tongue 7 comprises that three gates 8 can realize folding.
As further improvement of the utility model, the syringe needle of described needle body 3 is circular.
As further improvement of the utility model, the minimum diameter of snap ring 6 is greater than the minimum diameter of tongue 7, is less than the maximum inner diameter of tongue 7, can make snap ring 6 clamp tongue 7, prevents needle body 3 landings.
Embodiment: a kind of inoculating needle for Microbiology Experiment, comprise handle 1, connecting rod 2 and needle body 3, described handle 1 and connecting rod 2 are integral type structure, one end of needle body 3 is fixedly connected with connecting rod 2 by dop 5, the snap ring 6 of dop 5 and tongue 7 are from top to bottom sleeved on described connecting rod 2 successively, when fixing needle body 3, boost snap ring 6 to handle end, the not bent ends of needle body is put into tongue 7, to needle end push-tight, gate 8 closures, clamping needle body 3, wherein, the minimum diameter of snap ring 6 is greater than the minimum diameter of tongue 7, be less than the maximum inner diameter of tongue 7, can make snap ring 6 clamp tongue 7, syringe needle is circular configuration, be provided with the barb 4 of indent on the top of handle 1, convenient suspension, wherein, described handle 1, connecting rod 2 and needle body 3 are cylindric, and wherein handle 1 is made for polythene material, and connecting rod 2 is made for stainless steel, and needle body 3 is made for the stronger platinum wire of toughness.
The step of applying this inoculating needle is as follows:
1. the installation of needle body or replacing, according to the difference of content of the test, bend to required shape by one end of needle body, boost snap ring to handle end, the not bent ends of needle body are put into tongue, to pin end push-tight snap ring.
2. hanging idle inoculating needle can hang over its setting on homemade horizon bar or line by the barb on handle.
In this specification sheets, the utility model is described with reference to its specific embodiment.But, still can make various amendments and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
