The threaded hole of adaptation.
Further, the fastener is the nut for being rotatably connected in the connecting rod periphery.
Further, the shelf is equipped with the adjusting mechanism for adjusting the installation bore dia.
To achieve the above object two, first will be more present invention also offers a kind of multiple temperature sensors to mapping method for testing
A temperature sensor is installed in the mounting hole on shelf, then is pushed multiple temperature sensors at the same time with cover board, makes multiple temperature
The probe of degree sensor is located at same level, then locks shelf and cover board with fastener, frock finally is dipped vertically into perseverance
Complete at the same time to try mapping multiple temperature sensors in warm working medium.
Beneficial effect
Compared with prior art, the present invention have the advantage that for：
The 1st, multiple temperature sensors are fixed to the probe that on the shelf, can guarantee that multiple temperature sensors by cover board
It is consistent to immerse the depth of constant temperature working medium, and conveniently does consistent adjustment, makes multiple temperature sensors under the same testing conditions
Do and mapping is tried in real time, effectively eliminate the error brought in test process due to condition difference, reduce and surveyed in stable state and dynamic
The measured deviation occurred in amount, makes the relatively reliable to mapping test result of multiple temperature sensors, and it is strong to repeat experiment reproducibility；
2nd, multiple temperature sensors are evenly arranged on shelf, are reduced sensor and are disturbed between each other；
3rd, black box is few, simple in structure, compact, and easy to operate, cost is low.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the present invention；
Fig. 2 is the cutting diagram of embodiment 2 in the present invention.
Wherein：1- shelves, 2- cover boards, 3- connecting rods, 4- mounting holes, 5- fasteners, 6- hoodles, 7- accommodating chambers, 8- springs.
Embodiment
The present invention is described further for specific embodiment in below in conjunction with the accompanying drawings.
Embodiment 1
Refering to Fig. 1, a kind of multiple temperature sensors to marking test fixture, including shelf 1, above shelf 1 and can phase
To 1 upper and lower displacement of shelf with the cover board 2 that pushes multiple temperature sensors and through shelf 1 and the connecting rod 3 of cover board 2, shelf 1
It is made with cover board 2 of corrosion-and high-temp-resistant material, high using process stability, service life length, shelf 1 is equipped with multiple be used for
Temperature sensor mounted mounting hole 4,3 both ends of connecting rod are respectively equipped with the fastener 5 for locking shelf 1 and cover board 2, shelf 1 with
Cover board 2 is coaxially arranged, and the axle center of connecting rod 3 is overlapped with the axle center of shelf 1 and cover board 2, by cover board 2 by multiple temperature sensor pressures
Fasten on shelf 1, can guarantee that the depth of the probe immersion constant temperature working medium of multiple temperature sensors is consistent, and conveniently do consistent
