步骤一、将左连接部放置在所述固定部内，并使得左连接部中的弹片卡接在对应的卡槽内部，此时的弹片处于收缩状态；Step 1. Place the left connecting part in the fixing part, and make the elastic piece in the left connecting part snap into the corresponding slot, and the elastic piece is in a retracted state at this time;
步骤二、将带有电线的测试探针依次穿过右连接部、套有固定部的左连接部内，并将试探枕头固定在左连接部的卡接管内；Step 2: Pass the test probe with wires through the right connecting part and the left connecting part sleeved with the fixing part in turn, and fix the testing pillow in the clamping tube of the left connecting part;
步骤三、将右连接部的连接管卡接在左连接部的连接管内，使得右连接部的弹片与对应的卡槽相抵；Step 3: Clamp the connecting pipe of the right connecting part in the connecting pipe of the left connecting part, so that the elastic piece of the right connecting part abuts against the corresponding card slot;
步骤四、将套有左连接部和右连接部的固定部穿插在套筒内，此时的套筒已经通过焊接或者螺钉固定在所述承载机构上的连接杆上；执行步骤六；Step 4: Insert the fixing part covering the left connecting part and the right connecting part into the sleeve, and the sleeve at this time has been fixed on the connecting rod on the bearing mechanism by welding or screws; Go to step 6;
步骤五、当所述承接管、连接管和卡接管在同一轴向处开设有缝隙时，测试探针无需同时依次穿过右连接部、套有固定部的左连接部内，只需先将测试探针固定在套有固定部的左连接部内，然后再将导线部分通过缝隙渗透到右连接部内，安装更为便捷；同时，因为弹片的作用，会导致卡接管的外壁与固定部的内壁存在间隙，因此测试探针在外力的作用下会发生稍微的位置变动，因此在所述卡接管与所述承接管之间设置有向外扩张的卡片，所述卡片用于支撑卡接管的外壁与固定部的内壁，避免卡接管在固定部内发生偏移，从而确保了测试探针不会发生偏移；执行步骤六；Step 5. When the receiving pipe, the connecting pipe and the clamping pipe are provided with slits in the same axial direction, the test probe does not need to pass through the right connecting part and the left connecting part sleeved with the fixing part in sequence at the same time. The probe is fixed in the left connection part covered with the fixed part, and then the wire part penetrates into the right connection part through the gap, which is more convenient to install; at the same time, due to the action of the elastic sheet, the outer wall of the clamping tube and the inner wall of the fixing part will exist. Therefore, the position of the test probe will change slightly under the action of external force. Therefore, an outwardly expanding card is arranged between the clamping tube and the receiving tube, and the card is used to support the outer wall of the clamping tube and the outer wall of the clamping tube. The inner wall of the fixed part prevents the clamping tube from being displaced in the fixed part, thus ensuring that the test probe will not be displaced; perform step 6;
步骤六、螺纹杆部分位于螺纹孔内，此时止挡圈与所述安装座的顶部之间留有足够的空间，即位于安装座内部的球体是松动的；Step 6. The threaded rod is partially located in the threaded hole. At this time, there is enough space between the stop ring and the top of the mounting seat, that is, the sphere inside the mounting seat is loose;
步骤七、根据测试探针的方向需求，转动球体使得球体上的连接杆所在的方向改变，当转向到所需位置时，转动螺纹杆使得位于螺纹孔内的螺纹杆长度增加，直至螺纹杆的末端于所述止挡圈相抵，并推送所述止挡圈向上移动，止挡圈与所述安装座的顶部之间的空间变小，直至球体被固定在安装座的内部，方向固定。Step 7. According to the direction requirements of the test probe, rotate the sphere to change the direction of the connecting rod on the sphere. When turning to the required position, rotate the threaded rod to increase the length of the threaded rod located in the threaded hole until the threaded rod reaches the desired position. The end abuts against the stop ring and pushes the stop ring to move upward, the space between the stop ring and the top of the mounting seat becomes smaller until the ball is fixed inside the mounting seat and the direction is fixed.

本发明的实施方式Embodiments of the present invention
下面结合附图说明和具体实施例对本发明做进一步的描述。The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
申请人经研究发现：因为测试探针在进入流动环境后受到外力作用，如果对测试探针没有很好的固定作用则测试探针很容易在外力的作用下发生倾斜甚至掉落，影响测试探针与流动体接触或者分离的时间段。因为测试探针是与转换器、移动终端及检测电路形成闭合回路，因此如果采用直接焊接的方式则会产生电路的干涉，影响数据的输出。The applicant has found through research that: because the test probe is subjected to external force after entering the flow environment, if the test probe is not well fixed, the test probe will easily tilt or even fall under the action of external force, affecting the test probe. The period of time during which the needle is in contact with or separated from the fluid. Because the test probe forms a closed loop with the converter, the mobile terminal and the detection circuit, if the direct welding method is adopted, the circuit interference will occur, which will affect the data output.

如图1所示，一种流体流动测试探针7固定装置包括：承载机构5，所述承载机构5用于设置流体的内部，并给测试探针7提供固定需求。当需要测试探针7进行检测时将测试探针7安装固定在所述承载机构5上即可。所述承载机构5上固定焊接有套筒4，所述套筒4用于固定左连接部1、右连接部2和固定部3。其中，所述右连接部2与所述左连接部1结构相同且能够与所述左连接部1相互卡接；所述固定部3用于同时套接左连接部1和右连接部2；所述套筒4套接在所述固定部3上用于对左连接部1和右连接部2起到收紧作用。在安装时，首先将左连接部1与右连接部2相互卡接构成连接件，然后将试探针依次穿过所述连接件，使得所述测试探针7和与所述测试探针7相连的导线预埋在所述连接件的内部，最后通过固定部3将左连接部1与右连接部2固定并卡紧在所述套筒4内。As shown in FIG. 1 , a fluid flow test probe 7 fixing device includes: a bearing mechanism 5 , the bearing mechanism 5 is used to set the interior of the fluid and provide fixing requirements for the test probe 7 . When the test probe 7 needs to be tested, the test probe 7 can be installed and fixed on the carrying mechanism 5 . A sleeve 4 is fixedly welded on the bearing mechanism 5 , and the sleeve 4 is used for fixing the left connecting part 1 , the right connecting part 2 and the fixing part 3 . Wherein, the right connecting part 2 has the same structure as the left connecting part 1 and can be mutually clamped with the left connecting part 1; the fixing part 3 is used to sleeve the left connecting part 1 and the right connecting part 2 at the same time; The sleeve 4 is sleeved on the fixing part 3 for tightening the left connecting part 1 and the right connecting part 2 . During installation, firstly, the left connecting part 1 and the right connecting part 2 are clamped to each other to form a connecting piece, and then the test probes are passed through the connecting piece in turn, so that the test probes 7 and the test probes 7 are connected to each other. The connected wires are pre-embedded inside the connecting piece, and finally the left connecting part 1 and the right connecting part 2 are fixed and clamped in the sleeve 4 through the fixing part 3 .
在进一步的实施中，所述左连接部1包括：承接管101、连接管102、卡接管103和弹片104。所述连接管102固定在所述承接管101的一端，所述卡接管103固定在所述承接管101的另一端处。在本实施例中，所述弹片104的个数为两个，呈对称的沿所述连接管102的径向设置在所述连接管102壁处。所述弹片104的末端与所述连接管102的内壁之间具有大于0°的夹角，所述弹片104与连接管102和承接管101的连接处之间存在一定的距离；所述卡接管103的内径不大于测试探针7的外径。所述卡接管103与所述承接管101之间设置有向外扩张的卡片105；所述固定部3的内侧壁对称开设有向内的卡槽302。In a further implementation, the left connecting part 1 includes: a receiving pipe 101 , a connecting pipe 102 , a snap pipe 103 and an elastic piece 104 . The connecting pipe 102 is fixed at one end of the receiving pipe 101 , and the snap pipe 103 is fixed at the other end of the receiving pipe 101 . In this embodiment, the number of the elastic pieces 104 is two, which are symmetrically arranged on the wall of the connecting pipe 102 along the radial direction of the connecting pipe 102 . There is an included angle between the end of the elastic piece 104 and the inner wall of the connecting pipe 102 greater than 0°, and there is a certain distance between the elastic piece 104 and the connection between the connecting pipe 102 and the receiving pipe 101; the clamping pipe The inner diameter of 103 is not larger than the outer diameter of test probe 7 . An outwardly expanding card 105 is disposed between the clamping pipe 103 and the receiving pipe 101 ; an inward clamping groove 302 is symmetrically opened on the inner side wall of the fixing portion 3 .
在使用的过程中，首先将右连接部2的卡接管103卡接在左连接部1的卡接管103内，随后将测试探针7穿过右连接部2与左连接部1构成的连接件，并固定在的任意一端的卡接管103内，使得与测试探针7导线预埋在构成的连接件内。In the process of use, firstly snap the snap tube 103 of the right connecting part 2 into the snap tube 103 of the left connecting part 1 , and then pass the test probe 7 through the connecting piece formed by the right connecting part 2 and the left connecting part 1 , and fixed in the snap tube 103 at either end, so that the wire with the test probe 7 is embedded in the connecting piece.
左连接部1与右连接部2直接卡接后构成的连接件的结构是不稳定的，因此需要固定部3对其进行固定。所述固定部3的内部内侧壁对称开设有向内的卡槽302，所述固定部3套接在连接件上，且使得两端的卡槽302分别与对应的弹片104相卡接。The structure of the connecting member formed after the left connecting portion 1 and the right connecting portion 2 are directly clamped is unstable, so the fixing portion 3 is required to fix it. The inner inner wall of the fixing portion 3 is symmetrically provided with inward locking grooves 302 , and the fixing portion 3 is sleeved on the connector so that the locking grooves 302 at both ends are respectively locked with the corresponding elastic pieces 104 .
为了将测试探针7固定承载机构5上，因此设计了用于与测试探针7固定连接的套筒4。所述套筒4与固定部3通过以下结构实现连接：所述固定部3的外壁沿其轴向对称设置有偶数个压片301，所述压片301的竖截面为三角形，即所述压片301与所述固定部3的外壁之间构成弹性空间；所述套筒4上开设有偶数个对接槽303，所述对接槽303与所述压片301的位置和个数一致。In order to fasten the test probe 7 to the carrier 5 , a sleeve 4 for the fixed connection to the test probe 7 is therefore designed. The sleeve 4 and the fixing part 3 are connected through the following structure: the outer wall of the fixing part 3 is symmetrically arranged with an even number of pressing pieces 301 along its axial direction, and the vertical cross-section of the pressing pieces 301 is a triangle, that is, the pressing An elastic space is formed between the sheet 301 and the outer wall of the fixing portion 3 ; the sleeve 4 is provided with an even number of butting grooves 303 , and the positions and numbers of the butting grooves 303 are consistent with the pressing sheets 301 .
上述安装件的安装过程如下：首先，左连接部1放置在所述固定部3内，并使得左连接部1中的弹片104卡接在对应的卡槽302内，此时弹片104属于收缩状态。随后将测试探针7头依次穿过右连接部2、套有固定部3的左连接部1内，并将测试探针7固定在左连接部1的卡接管103内；然后将右连接部2的连接管102卡接在左连接部1的连接管102内，并使得右连接部2的弹片104与对应的卡槽302相抵；最后将套有左连接部1和右连接部2的固定部3穿插在套筒4内，在穿插的过程中压片301从挤压状态转化到正常状态，最后压片301位于对接槽303内。The installation process of the above-mentioned mounting part is as follows: First, the left connecting part 1 is placed in the fixing part 3, and the elastic piece 104 in the left connecting part 1 is clamped in the corresponding slot 302. At this time, the elastic piece 104 is in a retracted state . Then the test probes 7 are passed through the right connecting part 2 and the left connecting part 1 which is sheathed with the fixing part 3 in turn, and the test probes 7 are fixed in the clamping tube 103 of the left connecting part 1; then the right connecting part is The connecting pipe 102 of The part 3 is inserted into the sleeve 4. During the insertion process, the pressing piece 301 is transformed from the squeezed state to the normal state, and finally the pressing piece 301 is located in the butting groove 303.
在上述实施例中，所述卡接管103的内径不大于测试探针7的外径。In the above embodiment, the inner diameter of the snap tube 103 is not greater than the outer diameter of the test probe 7 .
但是考虑到正极针头与负极针头已经通过导线构成了一个回路，因此在上述安装的过程中，由于导线的干涉会给整个穿插的过程带来不便，因此基于上述安装件做了一下调整。However, considering that the positive needle and the negative needle have formed a loop through the wire, in the above installation process, the interference of the wire will bring inconvenience to the whole process of interspersed, so based on the above installation parts made some adjustments.
作为新的实施例，所述承接管101、连接管102和卡接管103在同一轴向处开设有缝隙6；所述承接管101和连接管102上的缝隙6便于两者相互卡接；所述卡接管103上的缝隙1109便于紧固测试探针7。As a new embodiment, the receiving pipe 101, the connecting pipe 102 and the clamping pipe 103 are provided with a slit 6 in the same axial direction; the slit 6 on the receiving pipe 101 and the connecting pipe 102 is convenient for the two to be snapped together; The slot 1109 on the snap tube 103 is convenient to fasten the test probe 7 .
该缝隙6的设置直接导致了对左连接部1的连接管102和右连接部2的连接管102的内径相同也可以实现卡接，即在卡接的过程中位于内部的连接管102中的缝隙6被挤压即可。同时卡接管103的内径小于正极针头或者负极针头也可以实现对针头的固定连接，甚至其固定作用相比于无缝隙6时的更为牢固。因为卡接管103的内径小于正极针头或者负极针头的外径，其因缝隙6的存在，针头对卡接管103有着挤压的作用，增大了摩擦力，更为牢固。The arrangement of the slot 6 directly leads to the fact that the inner diameter of the connecting pipe 102 of the left connecting part 1 and the connecting pipe 102 of the right connecting part 2 can also be clamped, that is, the inner diameter of the connecting pipe 102 can be clamped during the clamping process. The gap 6 can be squeezed. At the same time, the inner diameter of the snap tube 103 is smaller than that of the positive needle or the negative needle, so that the needle can be fixedly connected, and even its fixing effect is stronger than that without the gap 6 . Because the inner diameter of the clip tube 103 is smaller than the outer diameter of the positive or negative needle tip, due to the existence of the gap 6, the needle has a pressing effect on the clip tube 103, which increases the friction force and makes it firmer.
同时，在安装时，针头无需同时依次穿过右连接部2、套有固定部3的左连接部1内，可以先将针头固定在套有固定部3的左连接部1内，然后再将导线部分通过缝隙6渗透到右连接部2内，安装更为便捷。At the same time, during installation, the needle does not need to pass through the right connecting part 2 and the left connecting part 1 sleeved with the fixing part 3 at the same time. The wire part penetrates into the right connecting part 2 through the slit 6, and the installation is more convenient.
因为弹片104的作用，会导致卡接管103的外壁与固定部3的内壁存在间隙，因此针头在外力的作用下会发生稍微的位置变动，因此在所述卡接管103与所述承接管101之间设置有向外扩张的卡片105，所述卡片105用于支撑卡接管103的外壁与固定部3的内壁，避免卡接管103在固定部3内发生偏移，从而确保了针头不会发生偏移。Due to the action of the elastic piece 104, there will be a gap between the outer wall of the snap tube 103 and the inner wall of the fixing portion 3, so the needle will slightly change its position under the action of the external force. An outwardly expanding card 105 is arranged between the two, and the card 105 is used to support the outer wall of the clamping tube 103 and the inner wall of the fixing part 3, so as to prevent the clamping tube 103 from shifting in the fixing part 3, thereby ensuring that the needle does not deviate. shift.
如图7所示，所述承载机构5包括：内部为空心结构的安装座501，固定在所述安装座501内部的环形座502，放置在所述环形座502上的环形垫圈503，从所述环形垫圈503的内表面向下延伸至环形座502内部的止挡圈504，在止挡圈504与所述安装座501的顶部之间的球体505，开设在所述安装座501与环形座502上的螺纹孔，以及用于同时穿过安装座501上的螺纹孔与环形座502上的螺纹孔的螺纹杆506；所述球体505上固定有连接杆507，所述连接杆507用于与所述套筒4固定连接。As shown in FIG. 7 , the carrying mechanism 5 includes: a mounting seat 501 with a hollow structure inside, an annular seat 502 fixed inside the mounting seat 501, an annular washer 503 placed on the annular seat 502, The inner surface of the annular gasket 503 extends downward to the stop ring 504 inside the annular seat 502, and the sphere 505 between the stop ring 504 and the top of the mounting seat 501 is opened between the mounting seat 501 and the annular seat 502, and a threaded rod 506 for passing through the threaded hole on the mounting seat 501 and the threaded hole on the annular seat 502 at the same time; a connecting rod 507 is fixed on the ball 505, and the connecting rod 507 is used for It is fixedly connected with the sleeve 4 .
为了螺纹杆506能够在止挡圈504向上推送，进一步缩小止挡圈504与所述安装座501的顶部之间的空间，对球体505起到固定的作用，故所述止挡圈504的直径从上至下逐渐变小，设定位于所述环形座502内部的螺纹杆506的端部为末端；所述螺纹杆506的末端处的直径从外之内之间变小，竖截面为等腰梯形；所述螺纹杆506在内外螺纹的传动下，其末端能够与所述止挡圈504相接触，并促使环形座502上移。In order that the threaded rod 506 can be pushed upward on the stop ring 504, the space between the stop ring 504 and the top of the mounting seat 501 is further reduced, and the sphere 505 is fixed, so the diameter of the stop ring 504 is It gradually decreases from top to bottom, and the end of the threaded rod 506 inside the annular seat 502 is set as the end; the diameter of the end of the threaded rod 506 decreases from the outside to the inside, and the vertical section is an isosceles trapezoid ; The threaded rod 506 is driven by internal and external threads, and its end can be in contact with the stop ring 504, and urge the annular seat 502 to move up.
所述安装座501的顶部呈聚拢状，避免球体505在止挡圈504的作用下与所述安装座501发生脱离。The top of the mounting seat 501 is in a gathered shape to prevent the ball 505 from being separated from the mounting seat 501 under the action of the stop ring 504 .
具体包括以下步骤：Specifically include the following steps:
步骤一、将左连接部1放置在所述固定部3内，并使得左连接部1中的弹片104卡接在对应的卡槽302内部，此时的弹片104处于收缩状态；Step 1. Place the left connecting part 1 in the fixing part 3, and make the elastic pieces 104 in the left connecting part 1 snap into the corresponding card slots 302, and the elastic pieces 104 are in a retracted state at this time;
步骤二、将带有电线的测试探针7依次穿过右连接部2、套有固定部3的左连接部1内，并将试探枕头固定在左连接部1的卡接管103内；Step 2: Pass the test probe 7 with the electric wire through the right connecting part 2 and the left connecting part 1 sleeved with the fixing part 3 in turn, and fix the probe pillow in the clamping tube 103 of the left connecting part 1;
步骤三、将右连接部2的连接管102卡接在左连接部1的连接管102内，使得右连接部2的弹片104与对应的卡槽302相抵；Step 3: The connecting pipe 102 of the right connecting part 2 is clamped into the connecting pipe 102 of the left connecting part 1, so that the elastic pieces 104 of the right connecting part 2 are in contact with the corresponding card slots 302;
步骤四、将套有左连接部1和右连接部2的固定部3穿插在套筒4内，此时的套筒4已经通过焊接或者螺钉固定在所述承载机构5上的连接杆507上；执行步骤六；Step 4: Insert the fixing part 3 covered with the left connecting part 1 and the right connecting part 2 into the sleeve 4. At this time, the sleeve 4 has been fixed on the connecting rod 507 on the bearing mechanism 5 by welding or screws. ; Execute step 6;
步骤五、当所述承接管101、连接管102和卡接管103在同一轴向处开设有缝隙6时，测试探针7无需同时依次穿过右连接部2、套有固定部3的左连接部1内，只需先将测试探针7固定在套有固定部3的左连接部1内，然后再将导线部分通过缝隙6渗透到右连接部2内，安装更为便捷；同时，因为弹片104的作用，会导致卡接管103的外壁与固定部3的内壁存在间隙，因此测试探针7在外力的作用下会发生稍微的位置变动，因此在所述卡接管103与所述承接管101之间设置有向外扩张的卡片105，所述卡片105用于支撑卡接管103的外壁与固定部3的内壁，避免卡接管103在固定部3内发生偏移，从而确保了测试探针7不会发生偏移；执行步骤六；Step 5. When the receiving pipe 101, the connecting pipe 102 and the clamping pipe 103 are provided with the slit 6 in the same axial direction, the test probe 7 does not need to pass through the right connecting part 2 and the left connecting part 3 sleeved in sequence at the same time. In part 1, it is only necessary to fix the test probe 7 in the left connecting part 1 covered with the fixing part 3, and then penetrate the wire part into the right connecting part 2 through the gap 6, which is more convenient for installation; at the same time, because The action of the shrapnel 104 will cause a gap between the outer wall of the clamping tube 103 and the inner wall of the fixing part 3, so the test probe 7 will slightly change its position under the action of external force, so the clamping tube 103 and the receiving tube will have a slight position change. An outwardly expanding card 105 is arranged between 101, the card 105 is used to support the outer wall of the clamping tube 103 and the inner wall of the fixing part 3, so as to prevent the clamping tube 103 from shifting in the fixing part 3, thereby ensuring the test probe 7. There will be no offset; go to step six;
步骤六、螺纹杆506部分位于螺纹孔内，此时止挡圈504与所述安装座501的顶部之间留有足够的空间，即位于安装座501内部的球体505是松动的；Step 6: Part of the threaded rod 506 is located in the threaded hole. At this time, there is enough space between the stop ring 504 and the top of the mounting seat 501, that is, the sphere 505 inside the mounting seat 501 is loose;
