Because the test probe forms a closed loop with the converter, the mobile terminal and the detection circuit, if the direct welding mode is adopted, circuit interference can be generated, and data output is influenced.
Therefore, in order to solve the above-mentioned problems, the applicant developed a fluid flow test probe fixing apparatus and a fixing method thereof, including: the connecting device comprises a left connecting part 1, a right connecting part 2, a fixing part 3, a sleeve 4, a bearing mechanism 5, a gap 6, a bearing pipe 101, a connecting pipe 102, a clamping pipe 103, an elastic sheet 104, a clamping sheet 105, a pressing sheet 301, a clamping groove 302, a mounting seat 501, an annular seat 502, an annular gasket 503, a stop ring 504, a sphere 505, a threaded rod 506 and a connecting rod 507.
As shown in fig. 1, a fluid flow test probe 7 fixture includes: a carrier means 5, said carrier means 5 being used to arrange the interior of the fluid and to provide the fixing requirements for the test probe 7. When the test probe 7 is required to be detected, the test probe 7 is installed and fixed on the bearing mechanism 5. The bearing mechanism 5 is fixedly welded with a sleeve 4, and the sleeve 4 is used for fixing the left connecting part 1, the right connecting part 2 and the fixing part 3. The right connecting part 2 and the left connecting part 1 are identical in structure and can be mutually clamped with the left connecting part 1; the fixed part 3 is used for sleeving the left connecting part 1 and the right connecting part 2 at the same time; the sleeve 4 is sleeved on the fixing portion 3 and used for tightening the left connecting portion 1 and the right connecting portion 2. When the test probe is installed, the left connecting portion 1 and the right connecting portion 2 are firstly clamped with each other to form a connecting piece, then the probe needles sequentially penetrate through the connecting piece, the test probe 7 and a lead connected with the test probe 7 are embedded in the connecting piece, and finally the left connecting portion 1 and the right connecting portion 2 are fixed and clamped in the sleeve 4 through the fixing portion 3.
In a further implementation, the left connection part 1 comprises: bearing pipe 101, connecting pipe 102, clamping pipe 103 and spring plate 104. The connection pipe 102 is fixed to one end of the socket 101, and the snap pipe 103 is fixed to the other end of the socket 101. In this embodiment, the number of the elastic pieces 104 is two, and the two elastic pieces are symmetrically arranged on the wall of the connecting pipe 102 along the radial direction of the connecting pipe 102. An included angle larger than 0 degree is formed between the tail end of the elastic sheet 104 and the inner wall of the connecting pipe 102, and a certain distance is reserved between the elastic sheet 104 and the connecting part of the connecting pipe 102 and the adapting pipe 101; the inside diameter of the bayonet tube 103 is not greater than the outside diameter of the test probe 7. An outward expansion card 105 is arranged between the clamping pipe 103 and the bearing pipe 101; the inner side wall of the fixing part 3 is symmetrically provided with inward clamping grooves 302.
In the use process, the clamping pipe 103 of the right connecting part 2 is clamped in the clamping pipe 103 of the left connecting part 1, and then the test probe 7 penetrates through the connecting piece formed by the right connecting part 2 and the left connecting part 1 and is fixed in the clamping pipe 103 at any one end, so that a wire of the test probe 7 is embedded in the formed connecting piece.
The structure of the connecting piece formed by directly clamping the left connecting part 1 and the right connecting part 2 is unstable, so that the fixing part 3 is required to fix the connecting piece. Inward clamping grooves 302 are symmetrically formed in the inner side wall of the fixing portion 3, the fixing portion 3 is connected to the connecting piece in a sleeved mode, and the clamping grooves 302 at the two ends are connected with the corresponding elastic pieces 104 in a clamped mode respectively.
In order to fasten the test probe 7 to the support means 5, the sleeve 4 is designed for a fixed connection to the test probe 7. The sleeve 4 is connected with the fixing part 3 through the following structure: an even number of pressing sheets 301 are symmetrically arranged on the outer wall of the fixing part 3 along the axial direction of the fixing part, the vertical section of each pressing sheet 301 is triangular, and an elastic space is formed between each pressing sheet 301 and the outer wall of the fixing part 3; an even number of butt joint grooves 303 are formed in the sleeve 4, and the positions and the numbers of the butt joint grooves 303 are consistent with those of the pressing sheets 301.
The installation process of the installation part is as follows: firstly, the left connecting part 1 is placed in the fixing part 3, and the elastic sheet 104 in the left connecting part 1 is clamped in the corresponding clamping groove 302, and at this moment, the elastic sheet 104 is in a contraction state. Then, the head of the test probe 7 sequentially penetrates through the right connecting part 2 and the left connecting part 1 sleeved with the fixing part 3, and the test probe 7 is fixed in the clamping pipe 103 of the left connecting part 1; then, the connecting pipe 102 of the right connecting part 2 is clamped in the connecting pipe 102 of the left connecting part 1, and the elastic sheet 104 of the right connecting part 2 is abutted against the corresponding clamping groove 302; and finally, inserting the fixing part 3 sleeved with the left connecting part 1 and the right connecting part 2 into the sleeve 4, converting the pressing sheet 301 from a squeezing state to a normal state in the inserting process, and finally positioning the pressing sheet 301 in the butt joint groove 303.
In the above embodiment, the inner diameter of the bayonet tube 103 is not greater than the outer diameter of the test probe 7.
However, considering that the positive and negative needles already form a loop through the wire, the interference of the wire during the installation process may cause inconvenience to the whole insertion process, and thus the adjustment is made based on the installation member.
As a new embodiment, the bearing pipe 101, the connecting pipe 102 and the clamping pipe 103 are provided with a gap 6 at the same axial position; the gaps 6 on the bearing pipe 101 and the connecting pipe 102 are convenient for the clamping connection of the bearing pipe and the connecting pipe; a slot 1109 in the bayonet tube 103 facilitates securing the test probe 7.
The arrangement of the gap 6 directly results in that the inner diameters of the connecting pipes 102 of the left connecting part 1 and the right connecting part 2 are the same, and clamping can also be realized, namely the gap 6 in the connecting pipe 102 located inside is squeezed in the clamping process. Meanwhile, the inner diameter of the clamping tube 103 is smaller than that of the positive needle or the negative needle, so that the needle can be fixedly connected, and the fixing effect is firmer than that of the needle without the gap 6. Because the inner diameter of the clamping tube 103 is smaller than the outer diameter of the positive needle or the negative needle, the needle has an extrusion effect on the clamping tube 103 due to the existence of the gap 6, so that the friction force is increased, and the clamping tube is firmer.
Meanwhile, when the needle is installed, the needle does not need to simultaneously penetrate through the right connecting part 2 and the left connecting part 1 sleeved with the fixing part 3 in sequence, the needle can be fixed in the left connecting part 1 sleeved with the fixing part 3, then the wire part penetrates into the right connecting part 2 through the gap 6, and the installation is more convenient.
Because the effect of shell fragment 104 can lead to the outer wall of joint pipe 103 and the inner wall of fixed part 3 to have the clearance, consequently the syringe needle can take place slight position change under the effect of external force, consequently joint pipe 103 with be provided with outside expansion's card 105 between adapting pipe 101, card 105 is used for supporting the outer wall of joint pipe 103 and the inner wall of fixed part 3, avoids joint pipe 103 to take place the skew in fixed part 3 to ensured that the syringe needle can not take place the skew.

In order to push the threaded rod 506 upwards in the stop ring 504, the space between the stop ring 504 and the top of the mounting seat 501 is further reduced, and the ball 505 is fixed, so that the diameter of the stop ring 504 is gradually reduced from top to bottom, and the end of the threaded rod 506 positioned in the annular seat 502 is set as a tail end; the diameter at the tail end of the threaded rod 506 is reduced from outside to inside, and the vertical section of the threaded rod is in an isosceles trapezoid shape; the threaded rod 506, driven by the internal and external threads, has its end able to come into contact with the stop ring 504 and to urge the annular seat 502 upwards.
The top of the mounting seat 501 is in a gathering shape, so that the ball 505 is prevented from being separated from the mounting seat 501 under the action of the stop ring 504.
