Abstract
The utility model discloses an adjustable inoculating needle, its characterized in that: adjustable inoculating needle includes top cap (1), handle (2), handle interior protruding (3), handle head (4), protects nook closing member cover (5), spring (6), becket (7), syringe needle (8) and protect nook closing member cover outer protruding (9), wherein protects the nook closing member and overlaps the both ends of outer protruding (9) and handle head (4) supporting spring (6), and in addition, handle head (4) during the use, promote top cap (1) to living becket (7), and extend gradually syringe needle (8). Adjustable inoculating needle's syringe needle adjustable lengthwise energy -conservation does not greatly facilitate the use the person in the accurate inoculation of settlement within range. The part is except that becket and syringe needle are nichrome, and other materials are all made with the high temperature and high pressure material, and convenient disinfection still provides the protection for the user avoids scald and electric shock. It the inoculating needle that the practicality is very strong that relates to numerous fields.
Description
Technical field
The utility model relates to a kind of adjustable inoculating needle, belongs to test instrument, is widely used in microorganism, microbionation etc., contains the various fields such as environmental protection, medical science, biology, molecules, pharmacy, food.
Background technology
At present, the inoculating needle needle length that laboratory, each field uses is all fixing, cannot regulate, and operator is big in inoculation control difficulty, draws dynamic scope uncertain, the accuracy of impact inoculation position.
For solving the problem, the utility model proposes the inoculating needle of a kind of adjustable length, can conveniently make syringe needle extend, can shorten quickly again, handled easily person uses, and is a kind of desirable single bacterium colony Move tool, and practicality is extremely strong.
Summary of the invention
For achieving the above object, the utility model provides a kind of adjustable inoculating needle, it is characterized in that: described adjustable inoculating needle comprises top cover (1), handle (2), handle internal projection (3), handle head (4), protect nook closing member cover (5), spring (6), metal ring (7), syringe needle (8) and protect nook closing member cover outer lug (9), wherein protect nook closing member cover outer lug (9) and handle head (4) supports the two ends of firmly spring (6), and, handle head (4) supports metal ring (7), during use, promote top cover (1), syringe needle (8) extends gradually.
According to adjustable inoculating needle described in the utility model, it is characterised in that: nook closing member cover outer lug (9) directly contacts described handle internal projection (3) with protecting, and leans mutually.
According to adjustable inoculating needle described in the utility model, it is characterized in that: described handle head (4) is doline, its far-end is provided with Needle outlet, during use, nook closing member overlaps the common compression spring (6) of outer lug (9) to described handle head (4) with protecting, and described handle head (4) blocks metal ring (7).
According to adjustable inoculating needle described in the utility model, it is characterized in that: described metal ring (7) and syringe needle (8) are made for nichrome material, described top cover (1), handle (2), handle internal projection (3), handle head (4), protect nook closing member cover (5), spring (6) and protect nook closing member cover outer lug (9) and be made up of high temperature high-pressure resistant material.
As shown in Figure 1, in described handle, side-lower has handle internal projection, is used for protecting the two ends compression spring that nook closing member cover outer lug and handle head support firmly spring jointly, and handle is flexibly connected with handle head, it is possible to for convenience detach to firmly protecting nook closing member cover outer lug.
Described handle head is provided with the outlet of syringe needle, and whole handle head is doline, both can support metal ring and maintain static, and can support again spring; The described core that protects overlaps lower end and is divided into two lobes and is enclosed within metal ring, utilizes frictional force to bite syringe needle.
When described top cover is pressed downwards, can promote and protect nook closing member cover decline, doline button supports metal ring and does not move, be enclosed within metal ring protect nook closing member overlap lower end continue descending, two lobes being divided into depart from metallic sheath, naturally outside opened with certain angle, the syringe needle bitten declines under gravity, but the little segment distance that just declines. Because action triggers is very fast, by means of spring resilience, protect core and overlap lower end and return to again rapidly in metal ring, again bite syringe needle, so syringe needle declines a segment within the short period of time.
The lower end of described syringe needle support live hard object, press top cover, move down handle simultaneously, syringe needle just indentation protect nook closing member overlap in, syringe needle shorten.
Described parts are except metal ring and syringe needle are nichrome, and other materials are all made with high temperature high-pressure resistant material, can select high temperature, autoclave sterilization, avoid for user scalding and getting an electric shock providing protection simultaneously.
The beneficial effects of the utility model are: structure is simple, economic and practical, convenient to operation, syringe needle can telescopic adjustment flexibly, person greatly easy to use accurately inoculates in setting range, is the inoculating needle that a kind of practicality is very strong.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Fig. 1 is the structural representation of a kind of adjustable inoculating needle of the utility model.
Number in the figure illustrates:
Top cover 1
Handle 2
Handle internal projection 3
Handle head 4
Protect nook closing member cover 5
Spring 6
Metal ring 7
Syringe needle 8
Protect nook closing member cover outer lug 9.
Embodiment
A kind of adjustable inoculating needle as shown in Figure 1, by top cover, handle, handle internal projection, handle head, protect nook closing member cover, cover outer lug of protecting nook closing member, spring, metal ring, syringe needle form. When top cover 1 is pressed downwards, the nook closing member cover 5 that protects below can be promoted to decline, protect nook closing member cover outer lug 9 and doline handle head 4 supports the two ends of spring 6, spring 6 is compressed, to living, metal ring 7 does not move doline handle head 4 simultaneously, nook closing member cover 5 continuation of protecting being enclosed within metal ring 7 declines, the lower end being divided into two lobes departs from metallic sheath 7, naturally outside opened with certain angle, the syringe needle 8 bitten declines under gravity, but is a little segment distance, because action triggers is very fast, by means of spring 6 resilience, within the short period of time, syringe needle declines a segment. Constantly pressing top cover 1, syringe needle 8 extends gradually. When the lower end of syringe needle 8 support live a hard object, press top cover 1, move down handle 2 simultaneously, syringe needle 8 just indentation protect nook closing member cover 5 in, syringe needle become short.
