The utility model provides a temperature measurement structure, as shown in fig. 1 and fig. 2, includes temperature sensor 1, support 2, measured object 3 and fixing base 4, temperature sensor 1 sets up on the support 2 to with at least part the 3 contacts of measured object are connected, set up support piece 21 on the support 2, support piece 21 with form the measured object between the temperature sensor 1 and insert district 7, at least part the measured object 3 with the measured object inserts district 7 interference fit.
In practical use, because the object to be measured 3 is often in a vibration environment, the object to be measured 3 moves, so that the object to be measured cannot be parallel to and in contact with the temperature measuring surface of the temperature sensor 1, and the object to be measured 3 and the temperature measuring surface are not tightly attached. This will cause the temperature measured by the temperature sensor 1 to be inaccurate, and the control system will execute an incorrect temperature control measure according to the inaccurate temperature information, causing the related devices to be over-heated and burnt out.
The measured object 3 is inserted in the insertion area 7 and is in interference fit with the insertion area 7, so that the temperature measuring surface of the temperature sensor 1 can be always kept in contact with the measured object 3, and the temperature of the measured object 3 can be measured more accurately.
In some embodiments, the holder 2 is provided with a recess, as shown in fig. 2, in which the temperature sensor 1 is arranged. The recess can be better fixed with temperature sensor 1, prevents that temperature sensor 1 from breaking away from the operating position in rocking. The recess is at the terminal surface of one side that temperature sensor 1 put into, interior limit edges and corners department at the recess, set up chamfer or radius, can make temperature sensor 1 under the effect of direction, more smooth insert in the recess, the recess still sets up on the terminal surface of one side that temperature sensor 1 put into and has elastic blocking hook, when temperature sensor 1 puts into the recess, can will block the hook and remove the position that does not influence temperature sensor 1 and put into, put into the back when temperature sensor 1, blocking hook can block temperature sensor 1's terminal surface, make temperature sensor 1 can not break away from in the recess. If it is necessary to disengage the temperature sensor 1 from the recess, the blocking hook needs to be deformed to move to a position that does not affect the extraction of the temperature sensor 1.
In some embodiments, the groove is provided with an opening on a side facing the object to be measured 3, and the temperature sensor 1 is provided with a temperature measuring surface which is flush with or protrudes from an outer side surface of the opening. The temperature measuring surface protrudes out of the opening or is parallel and level to the opening, so that the temperature sensor 1 can be better attached to the measured object 3, and the temperature value measured by the temperature sensor 1 is closer to the true value.
In some embodiments, a support 21 is disposed on the bracket 2, and the support 21 and the temperature sensor 1 are respectively located on two sides of the object 3 to be measured. The support 21 and the temperature sensor 1 support the object 3 from two sides, and prevent the object 3 from moving relative to the fixed seat 4. And the support 21 can extrude the measured object 3 to the temperature measuring surface of the temperature sensor 1, so that the measured object 3 can be tightly attached to the temperature measuring surface of the temperature sensor 1 to obtain a more accurate temperature value of the measured object 3.
In some embodiments, the bracket 2 is provided with a shaft pin 5 on a side opposite to the temperature sensor 1, the fixing seat 4 is provided with a fixing hole, the shaft pin 5 is inserted into the fixing hole and connected, and the bracket 2, the temperature sensor 1 and the object to be measured 3 are movable relative to the fixing seat 4.
The bracket 2 comprises one side provided with the temperature sensor 1 and the other side opposite to the one side, the other side is provided with a shaft pin 5, and the shaft pin 5 is connected with the fixed seat 4 through a fixing hole. The support 2 can drive the temperature sensor 1 to rotate by taking the shaft pin 5 as a shaft, and when the measured object 3 rotates and displaces, the support 2 can drive the temperature sensor 1 to rotate along with the measured object 3, so that the temperature measuring surface of the temperature sensor 1 is always in contact with the measured object 3, and the temperature of the measured object 3 can be measured more accurately.
In some embodiments, the support 21 deforms as the ambient temperature changes. Under most circumstances, the ambient temperature of the measured object 3 can change greatly when in use, the gap between the measured object 3 and the temperature sensor 1 can increase along with the increase of the ambient temperature, so that the temperature sensor 1 cannot accurately measure the actual temperature of the measured object 3, the temperature measured by the temperature sensor 1 is inaccurate, and the control system can execute wrong temperature control measures according to inaccurate temperature information to cause the related devices to be burnt due to overhigh temperature. Therefore, when the ambient temperature increases, the volume of the support member 21 also increases to provide a larger pressure, so that the measured object 3 and the temperature sensor 1 are closely attached to each other, thereby ensuring that the temperature sensor 1 can accurately measure the actual temperature of the measured object 3. When the ambient temperature decreases, the volume of the support 21 also decreases, but the gap between the measured object 3 and the temperature sensor 1 also decreases, so that the measured object 3 and the temperature sensor 1 are closely attached.
The characteristic of the support 21 deforming with the change of the environmental temperature is that the support 21 can be made of a material with a large expansion rate, and the material with the large expansion rate can change the whole volume with the change of the environmental temperature. The supporting member 21 can also be made of a combination of materials with different expansion rates, and when the ambient temperature changes, the supporting member 21 made of the combination of materials with different expansion rates can bend or twist, so as to generate a greater pressure to be applied to the object 3 to be measured, so that the object 3 to be measured and the temperature sensor 1 can be tightly attached.
In some embodiments, the support member 21 is made of plastic, the shaft pin 5 is made of metal, and a portion of the shaft pin 5 is disposed in the support member 21. The support 21 made of plastic can be easily in interference fit with the object 3 to be measured, and generates extrusion force on the object 3 to be measured. However, the plastic material is easy to age and reduce elasticity during long-time extrusion, and the shaft pin 5 is arranged in the support 21, so that the support 2 can rotate, the support 21 can be reinforced, the overall elasticity level can be maintained, and the extrusion force of the measured object 3 caused by aging of the plastic material is prevented from being reduced.
In some embodiments, at least one protrusion is disposed on the contact surface of the support member 21 and the object 3 to be measured. Set up protruding can make support piece 21 better to the measured object 3 exert the extrusion force, both prevent that measured object 3 from taking place to remove, can make its laminating temperature sensor 1 again, obtain more accurate measured value.
In some embodiments, the support 21 applies a pressure to the contact surface of the temperature sensor 1, the pressure having a value of 0.05N-195N.
In order to test the effect of the pressure provided by the support 21 on the accuracy of the temperature sensor 1, the inventors made relevant tests. The inventor chooses the same measured object 3 and the same temperature sensors 1 are arranged on the same bracket 2. The method comprises the steps of selecting a test sensor to be arranged on a measured object 3 and tightly attached to the measured object 3, selecting different support members 21, enabling different support members 21 to provide different reset forces and different pressures between a temperature sensor 1 and the measured object 3, enabling the temperature of the measured object 3 to start rising after the measured object 3 works, enabling the temperature to tend to be stable after 20 minutes, recording a temperature value y collected by the test sensor and a temperature value x collected by the temperature sensor 1 connected with the different support members 21 at the same time, and calculating the ratio of x/y, wherein the ratio of x/y is greater than 99.95% and is an ideal state. The results are shown in Table 1.
Table 1: influence of the pressure provided by the support 21 on the accuracy of the temperature sensor 1
As can be seen from table 1, when the force applied by the support 21 to the object 3 to be measured is less than 0.05N, the temperature value acquired by the temperature sensor 1 is too different from the temperature value acquired by the test sensor, and the ratio of the temperature value acquired by the temperature sensor 1 to the temperature value acquired by the test sensor is less than 99.95%, so that the force applied by the support 21 to the object 3 to be measured by the inventor is greater than or equal to 0.05N, and when the force applied by the support 21 to the object 3 to be measured is greater than 195N, the temperature measured by the temperature sensor 1 is very close to the temperature measured by the test sensor, and then the greater force contrast value is not affected, and the support 21 providing a greater force will make the installation of the object 3 to be measured more difficult, so that the pressure provided by the support 21 selected by the inventor is 0.05N to 195N.
In some embodiments, the support 21 is chamfered or rounded at the corner on the side facing the object 3 at the end facing away from the bracket. The rounding or chamfering can guide the object to be measured 3 into the object to be measured insertion area 7, and prevent the support 21 from impacting the object to be measured 3 rigidly to damage the coating on the surface of the object to be measured 3, so that the resistance of the object to be measured 3 is increased, and the conductivity is reduced.
In some embodiments, the pivot pin 5 is integrally formed with the bracket 2, the pivot pin 5 includes a post 51 and a cap 52, the post 51 is connected to the bracket 2 at one end and connected to the cap 52 at the other end, the cap 52 has a radial dimension larger than that of the post 51, and a distance from a bottom of the cap 52 to the bracket 2 is greater than or equal to a thickness of the fixing seat 4. The fixing holes include a positioning groove 41 and a mounting hole 42 which are communicated with each other, as shown in fig. 3, the diameter of the mounting hole 42 is greater than or equal to the diameter of the cap body 52, and the width of the positioning groove 41 is greater than or equal to the diameter of the column 51 but smaller than the diameter of the cap body 52. The axle pin 5 is inserted into the mounting hole 42 and then transversely pushed into the positioning slot 41, and the diameter of the cap body 52 is larger than the width of the positioning slot 41 and smaller than the diameter of the mounting hole 42, so that the axle pin can pass through the mounting hole 42 and not pass through the positioning slot 41, and the aim of preventing the axle pin 5 from falling out of the positioning slot 41 is fulfilled.
Further, the cylinder 51 is further provided with an annular protrusion 53, as shown in fig. 2, the annular protrusion 53 can be in interference fit with the positioning groove 41.
Thus, when the temperature measuring device is installed, the shaft pin 5 can obliquely pass through the installation hole 42, the annular protrusion 53 is clamped above the positioning groove 41, the temperature sensor 1 is not perpendicular to the fixing seat 4 at the moment, as shown in fig. 4, the temperature measuring surface of the temperature sensor 1 faces the insertion direction of the measured object 3, and the inserted measured object 3 can prevent the measured object 3 from being inaccurate in insertion direction and being in rigid contact with the top of the temperature sensor 1, so that the temperature sensor 2 is damaged. After the temperature measuring surface of the temperature sensor 1 is designed, the measured object 3 is guided, and after the measured object 3 is inserted into the measured object insertion region 7, the annular protrusion 53 penetrates through the positioning groove 41 downwards by further force, so that the installation is completed, as shown in fig. 1. The thickness of the fixing seat 4 at the fixing hole is smaller than the thickness of other positions of the fixing seat 4, so that deformation is easy to occur, and the annular bulge 53 is conveniently clamped in. At the moment, the temperature measuring surfaces of the measured object 3 and the temperature sensor 1 are perpendicular to the fixed seat 4. The diameter of the cylinder 51 is preferably smaller than the width of the positioning groove 41, so that after installation, the shaft pin 5 can have a certain moving space, and when the object 3 to be measured shakes, the bracket 2 also has a moving amount, so that the phenomenon that the surface of the object 3 to be measured is damaged or the temperature sensor 1 is damaged due to too strong shaking force of the object 3 to be measured is prevented.
Further, the plane of the annular protrusion 53 forms an included angle with the cross section of the column 51. Thus, in the process of inserting the annular protrusion 53 into the positioning groove 41, the annular protrusion does not completely enter the positioning groove 41 at a time, but one side of the annular protrusion first enters the positioning groove 41 and then completely enters the positioning groove, so that the annular protrusion 53 can enter the positioning groove 41 more easily than the whole annular protrusion, and the force applied to the annular protrusion 53 can be smaller.
Furthermore, the annular protrusion 53 is smoothly transited to the column 51. This allows for less force to be required when applying force to move the annular projection 53 through the detent 41.
In some embodiments, the shaft pin 5 and the bracket 2 are of a separate structure, the bracket 2 is provided with a threaded hole on a side opposite to the temperature sensor 1, one side of the shaft pin 5 is provided with an external thread, the other side end of the shaft pin is provided with a nut, and the shaft pin 5 passes through the fixing hole and is in threaded connection with the threaded hole. The shaft pin 5 firstly passes through the fixing hole from the lower part and then is in threaded connection with the threaded hole of the bracket 2, and the rotating shaft 5 and the fixing seat 4 can be connected together through the nut. Before the nut is screwed, the position of the bracket 2 is adjusted by rotating by taking the shaft pin 5 as a shaft, and after the position is adjusted to a proper position, the nut is screwed to relatively fix the bracket 2 and the base 4.
In some embodiments, the bracket 2 is further provided with a clamping ring 8, the clamping ring 8 is provided with a through opening 81, and the width of the through opening 81 is smaller than the diameter of the clamping ring 8; the fixing seat 4 is provided with a fixing frame and a fixing shaft arranged on the fixing frame, the fixing shaft is clamped in the clamping ring 8 through the through opening 81, and the width of the through opening 81 is smaller than or equal to the diameter of the fixing shaft. The clamping ring 8 is clamped with the fixed shaft, so that the support 2 is arranged on the fixed seat 4, the fixed shaft needs to be pushed into the clamping ring 8 forcibly during installation, and the opening 81 is smaller than the diameter of the fixed shaft, so that the clamping ring 8 and the fixed shaft can be prevented from being separated easily.
