Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The sampling part of the existing oleic acid tester is generally protected by a turnover shell, so that the influence of external factors on internal detection during testing is avoided, a test tube for sampling is generally directly placed on an internal detection seat, and the operation can be carried out only by turning the shell every time the test is finished, which is more troublesome.
To solve this problem, referring to fig. 1-3, an oleic acid detecting device comprises: the device body 10 and the sampling mechanism 20.
Specifically, the sampling mechanism 20 is inserted into the upper surface of the device body 10, the sampling mechanism 20 includes an outer tube sleeve 21 and an inner tube 22 sleeved in the outer tube sleeve 21, the upper portion of the inner tube 22 is sealed, a sealing ring 214 is provided in the inner tube sleeve 21, a plurality of liquid inlets 221 are provided in the outer side of the inner tube 22, and the sealing ring 214 seals or opens the liquid inlets 221 when the outer tube sleeve 21 moves up and down along the outer wall of the inner tube 22.
That is, the outer tube sleeve 21 moves up and down on the outer side of the inner tube 22 to seal the liquid inlet 221 by the sealing ring 214, when the sealing ring 214 seals the liquid inlet 221, liquid can be added from above the outer tube sleeve 21, and then enters the sealing ring 214, the outer tube sleeve 21 and the inner tube 22, when the outer tube sleeve 21 is controlled to move down, the sealing ring 214 opens the sealing of the liquid inlet 221, at this time, the liquid enters the inner tube 22 along the liquid inlet 221, and when the liquid completely enters the inner tube 22, the outer tube sleeve 21 is controlled to move up, that is, the sealing ring 214 reseals the liquid inlet 221, so as to ensure the sealing performance of the inner tube 22 in the detection process.
In one embodiment, referring to fig. 2, the outer tube sleeve 21 has a tubular structure, a limiting portion 215 is disposed at the bottom of the outer tube sleeve 21, a positioning portion 222 is disposed at the outer side of the inner tube 22, and the positioning portion 222 is disposed at the upper portion of the limiting portion 215.
That is, by the cooperation of the positioning portion 222 and the limiting portion 215, the outer tube sleeve 21 cannot be separated from the inner tube 22 in a descending manner, and the position of the sealing ring 214 can be limited by the position of the positioning portion 222, so that the problem that the liquid cannot completely enter the inner tube 22 due to excessive pressing is avoided.
In one embodiment, referring to fig. 2 and 3, an inner cavity 211 is formed in the outer tube sleeve 21, the inner cavity 211 is in threaded connection with a pressing plate 212 with a hole on the surface, a spring 213 is disposed between the pressing plate 212 and the upper end of the inner test tube 22, and two ends of the spring 213 are fixed with the pressing plate 212 and the inner test tube 22 respectively.
Namely, the position restriction is provided through the pressing plate 212, the pressing plate 212 restricts the position of the spring 213, under the normal state, the spring 213 is slightly extruded by the gravity of the outer tube sleeve 21, the liquid circulates through the hole on the surface of the pressing plate 212, when the liquid needs to be filled into the inner tube 22, the outer tube sleeve 21 is extruded downwards, so that the outer tube sleeve 21 moves downwards, the spring 213 is extruded, due to the arrangement of the positioning part 222, the downward moving distance can be restricted, the problem of excessive extrusion can be avoided, the added liquid, namely the grease needing to be detected, can completely enter the inner tube 22, after the liquid enters the inner tube 22, the extrusion of the outer tube sleeve 21 is released, the spring 213 is deformed in a recovery mode, the outer tube sleeve 21 is lifted again, so that the sealing ring 214 is used for sealing the liquid inlet 221 again, the purpose of automatic sealing is achieved, and when the cleaning is needed, the whole sampling mechanism 20 is directly taken down, namely the outer tube sleeve 21 and the inner tube sleeve 22 can be directly taken out, and the pressing plate 212 in threaded connection needs to be taken down, and then the inner tube 22 and the outer tube sleeve 21 are separated for cleaning.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
