The technical solution of the utility model is such：A kind of multiple temperature sensors to marking test fixture, including shelf,
Above the shelf and can the relatively described shelf upper and lower displacement with the cover board that pushes multiple temperature sensors and pass through
The connecting rod of the shelf and cover board, the shelf are equipped with multiple for temperature sensor mounted mounting hole, the company
Bar both ends are respectively equipped with the fastener of the shelf and cover board locking.
As a further improvement, the shelf and the cover board are coaxially arranged, the axle center of the connecting rod with it is described
The axle center of shelf and cover board overlaps.
Further, the mounting hole is evenly arranged in the shelf periphery around the axle center of the shelf.
Further, the connecting rod is threaded rod, correspondingly, the shelf and cover board are equipped with and the connecting rod phase
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 regulating mechanism for adjusting the installation bore dia.
Advantageous effect
The utility model compared with prior art, have the advantage that for：
1, multiple temperature sensors are fixed to the probe that can guarantee multiple temperature sensors on the shelf by cover board
The depth for immersing constant temperature working medium is consistent, and conveniently does consistent adjustment, makes multiple temperature sensors under the same testing conditions
It does and mapping is tried in real time, effectively eliminate the error brought due to condition difference in test process, 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；
2, multiple temperature sensors are evenly arranged on shelf, are reduced sensor and are interfered between each other；
3, black box is few, simple in structure, compact, easy to operate, at low cost.

Fig. 1 is the dimensional structure diagram of the utility model；
Fig. 2 is the cutting diagram of embodiment 2 in the utility model.
Wherein：1- shelves, 2- cover boards, 3- connecting rods, 4- mounting holes, 5- fasteners, 6- hoodles, 7- accommodating chambers, 8- springs.
Specific implementation mode
Specific embodiment in below in conjunction with the accompanying drawings is described further the utility model.
Embodiment 1
Refering to fig. 1, a kind of multiple temperature sensors are to marking test fixture, including shelf 1, are located at the top of shelf 1 and can phase
To 1 upper and lower displacement of shelf with the cover board 2 that pushes multiple temperature sensors and across the connecting rod 3 of shelf 1 and cover board 2, shelf 1
It is made of corrosion-and high-temp-resistant material with cover board 2, using process stability height, service life is long, and 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
It fastens 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
Adjustment, make multiple temperature sensors do under the same testing conditions in real time to mapping try, effectively eliminate in test process by
In the error that condition difference is brought, reduces the measured deviation occurred in stable state and dynamic measure, make multiple temperature sensors
It is relatively reliable to mapping test result, repeat test reproducibility it is strong, tooling black box is few, simple in structure, compact, operation side
Just, at low cost.
Mounting hole 4 is evenly arranged in 1 periphery of shelf around the axle center of shelf 1, ensures that multiple temperature sensors are spaced from each other,
It reduces temperature sensor to interfere between each other, connecting rod 3 is threaded rod, correspondingly, shelf 1 and cover board 2 are equipped with and fit with 3 phase of connecting rod
The threaded hole matched, fastener 5 are the nut for being rotatably connected in the periphery of connecting rod 3, and cover board 2 is by the nuts of upper and lower ends by temperature sensor
