Description
Technical Field
The utility model belongs to the technical field of machinery, a novel test tube positioning seat is related to.
Background
In the test operation process, need to test tube location, current test tube directly adopts the test-tube rack location usually.
The upper portion and the lower part department of test-tube rack all have annular position sleeve, and the both ends of test tube are worn to establish and are formed the location in two position sleeve departments.
In order to ensure that the test tube can be stably inserted into the positioning sleeve, the size of the positioning sleeve is usually slightly larger than the outer diameter of the test tube. This results in tube positioning with loosening and poor stability.
Disclosure of Invention
The utility model aims at providing a convenient to use and high neotype test tube positioning seat of stability to the above-mentioned problem that prior art exists.
The purpose of the utility model can be realized by the following technical proposal:
the utility model provides a novel test tube positioning seat, including being massive body, its characterized in that still includes the position sleeve, guide bar and spring, above-mentioned position sleeve links firmly in body upper end department, and above-mentioned body lower part has the guiding hole that runs through its both sides, and above-mentioned guide bar wears to establish in guiding hole department, and the guide bar inner stretches out body one side and has the spring at this end, and the guide bar outer end stretches out the body opposite side and has the locating hole that is used for fixing a position the test tube at this end, and above-mentioned locating hole has the trend of retraction guiding hole department under the spring action of spring.
The upper part of the test tube is arranged in the positioning sleeve in a penetrating way, and the lower part of the test tube is arranged in the positioning hole in a penetrating way. The lateral part of the test tube can be attached to the lateral part of the body under the action of the elastic force of the spring. Therefore, the test tube can be effectively prevented from loosening, and the positioning stability is higher.
Certainly, when needing to take out the test tube by positioning seat department, exert external force and promote the guide bar and can make the guide bar drive the test tube and keep away from the body to guarantee that the body is conveniently unloaded.
In foretell novel test tube positioning seat, threaded connection has set nut in the guide bar inner, and above-mentioned spring housing leans on set nut and body lateral part respectively on the guide bar and the both ends of spring.
The positioning nut has two functions:
the first positioning device is used for positioning the end part of the spring;
its two, change the position of set nut on the guide bar after, can also suitably change spring force, finally change the effort size that the test tube leaned on the body.
In foretell novel test tube positioning seat, the body lateral part is stretched out with body formula structure as an organic whole and position sleeve to the position sleeve.
In foretell novel test tube positioning seat, the body lateral part department between position sleeve and the guiding hole links firmly the flexible gasket of connection.
Can avoid test tube and body rigid contact under the effect of gasket.
In foretell novel test tube positioning seat, the body lateral part has recessed connecting seat, and above-mentioned gasket inlays in connecting seat department and the gasket stretches out the body lateral part.
In the above-mentioned novel test tube positioning seat, the gasket is made of rubber material.
In foretell neotype test tube positioning seat, the locating hole is the bar hole.
Test tube width and locating hole width phase-match, such structure enables the smooth and easy location hole department of inserting of test tube lower extreme. Simultaneously, in case can also make the stable subsides of test tube paste in the body lateral part after the guide bar removes.
Compared with the prior art, this neotype test tube positioning seat is because the test tube can not only smooth and easy convenient insertion positioning seat, moreover, can form stable location after the test tube inserts the positioning seat, and the test tube can not become flexible, consequently, its stability is than higher.
Drawings
Fig. 1 is a schematic structural view of the novel test tube positioning seat.
In the figure, 1, a body; 1a, a guide hole; 1b, a connecting seat; 2. a positioning sleeve; 3. a guide bar; 3a, positioning holes; 4. a spring; 5. positioning a nut; 6. a gasket; 7. test tubes.
Detailed Description
As shown in fig. 1, this neotype test tube positioning seat is including being massive body 1, still include position sleeve 2, guide bar 3 and spring 4, above-mentioned position sleeve 2 links firmly in 1 upper end department of body, 1 lower part of above-mentioned body has the guiding hole 1a that runs through its both sides, above-mentioned guide bar 3 wears to establish in guiding hole 1a department, 3 inner ends of guide bar stretch out body 1 one side and have spring 4 at this end, 3 outer ends of guide bar stretch out body 1 opposite side and have the locating hole 3a that is used for fixing a position test tube 7 at this end, above-mentioned locating hole 3a has the trend of retraction guiding hole 1a department under spring 4's elastic force effect.
The inner end of the guide rod 3 is in threaded connection with a positioning nut 5, the spring 4 is sleeved on the guide rod 3, and two ends of the spring 4 are respectively abutted against the positioning nut 5 and the side part of the body 1.
The locating sleeve 2 and the body 1 are of an integrated structure, and the locating sleeve 2 extends out of the side portion of the body 1.
And a flexible gasket 6 is fixedly connected to the side part of the body 1 between the positioning sleeve 2 and the guide hole 1 a.
The side of the body 1 is provided with a concave connecting seat 1b, the gasket 6 is embedded in the connecting seat 1b, and the gasket 6 extends out of the side of the body 1.
The gasket 6 is made of rubber material.
The positioning holes 3a are strip-shaped holes.
The upper part of the test tube is arranged in the positioning sleeve in a penetrating way, and the lower part of the test tube is arranged in the positioning hole in a penetrating way. The lateral part of the test tube can be attached to the lateral part of the body under the action of the elastic force of the spring. Therefore, the test tube can be effectively prevented from loosening, and the positioning stability is higher.
Certainly, when needing to take out the test tube by positioning seat department, exert external force and promote the guide bar and can make the guide bar drive the test tube and keep away from the body to guarantee that the body is conveniently unloaded.
The size of the positioning sleeve 2 is slightly larger than the outer diameter of the test tube, and the structure can ensure that the test tube is stably inserted into the positioning sleeve 2. Of course, 7 lower extremes of test tube are compressed tightly between body and guide bar 3, and 7 lower extremes of test tube obtain stable positioning, and the test tube 7 upper end is only tentatively fixed a position, but still can be with 7 stable location of test tube in this positioning seat department like this to test tube 7 can not become flexible after obtaining the location.
