A kind of novel sensor
Technical field
This utility model belongs to detection means technical field, and in particular to a kind of novel sensor.
Background technology
Sensor is a kind of detection means, can experience measured information, and can be by the information experienced, by a set pattern
Rule is for conversion into the information output of the signal of telecommunication or other desired forms, to meet the transmission of information, processs, storage, display, record
With control etc. require.
Temperature sensor refers to the sensor that can be experienced temperature and be converted into usable output signal.Existing temperature sensor
Need when mounted additionally to increase multiple installing components, install comparatively laborious, it is relatively costly.
Utility model content
The purpose of this utility model is to solve the above problems, there is provided a kind of easy for installation, and structure is more simplified rational
Novel sensor.
To solve above-mentioned technical problem, the technical solution of the utility model is:A kind of novel sensor, including sleeve, set
Cylinder front end is connected with suction tray, and sleeve rear end is connected with end cap, and sensor body is located in sleeve;Sensor body outer wall is convex
Spacing preiection is provided with, spring housing is located at sensor body, and one end of spring is abutted with spacing preiection, and the other end is abutted with end cap;
Sleeve lining convexes to form limited step, and spacing preiection is abutted with limited step under the action of the spring, before sensor body
End probe reaches absorption tray bottom through limited step;The boss of circle is provided with the middle part of end cap, spring housing is located at boss;Sensing
Device body includes radio transmitter plate and battery, and front-end probe is connected with radio transmitter plate, radio transmitter plate with
Battery is connected.
Preferably, the end cap is connected with bush whorl.
Preferably, the front-end probe is temperature probe.
The beneficial effects of the utility model are:Novel sensor provided by the utility model when mounted, by absorption
Disk absorption on determinand surface, under the action of the spring, sensor body all the time with determinand reliable contacts, convenient to detect, nothing
Extra fixed component is needed, it is easy for installation, and structure is more simplified reasonable.Sensor body is realized by radio transmitter plate
Front-end probe detection signal is wirelessly transferred, using it is more convenient flexibly.

Specific embodiment
This utility model is described further with specific embodiment below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, a kind of novel sensor of the present utility model, including sleeve 1, suction tray 2, end cap 3 and biography
Sensor body 4, its middle sleeve 1 is hollow cylinder, sensor body 4 in the sleeve 1, suction tray 2 by made by rubber
1 front end of sleeve is sheathed on, end cap 3 is threadedly coupled with the rear end of sleeve 1, sleeve 1, suction tray 2 and end cap 3 closely connect, and pass through
Suction tray 2 can adsorb novel sensor on determinand surface, and sensor body 4 is contacted with determinand, convenient to detect.
Sensor body 4 includes housing, front-end probe 8, radio transmitter plate 9, battery 10 and bonnet 11, and housing has
Opening, forms internal cavity, and front-end probe 8, radio transmitter plate 9 and battery 10 are located in the cavity of housing, and bonnet 11 is used
In the opening for covering housing.Front-end probe 8 is temperature probe, and front-end probe 8 is connected with radio transmitter plate 9, wireless transmit
Circuit board 9 is connected with battery 10;Radio transmitter plate 9 includes power supply circuits, sample circuit, microprocessor, radio-frequency receiving-transmitting electricity
Road and antenna etc., so as to realize being wirelessly transferred for 8 detection signal of front-end probe.
Spacing preiection 5 is convexly equipped with the housing exterior walls of sensor body 4, spring 6 is sheathed on the housing of sensor body 4,
One end of spring 6 is abutted with spacing preiection 5, and the other end is abutted with end cap 3;1 inwall of sleeve convexes to form a circle limited step 7,
Spacing preiection 5 is abutted with limited step 7 in the presence of spring 6, and the front-end probe 8 of sensor body 4 is stretched through limited step 7
Go out to 2 bottom of suction tray;As shown in Fig. 2 the front-end probe 8 of sensor body 4 slightly stretches out in the front end of sleeve 1.Work as suction tray
At determinand surface, sensor body 4 is contacted with determinand surface for absorption, and spring 6 ensures sensor body 4 all the time with certain
Pressure is contacted with determinand surface, it is ensured that the accuracy of measurement.
It should be noted that as shown in Fig. 2 during reality processing and use, front-end probe 8 is located at sensor sheet
In the housing of body 4, not with determinand surface directly contact, but actual measurement is had no effect on.In order that front-end probe 8 with it is to be measured
Thing surface directly contact, can open up the hole passed through for front-end probe 8 on housing.
In order to be further ensured that the adhesive ability of suction tray 2, the inwall outer edge of suction tray 2 is provided with a circle adhesive layer
12, adhesive layer 12 is made up of emplastic, reusable.
In order to further position to spring 6 and sensor body 4, the boss 13 of circle in the middle part of end cap 3, is provided with, it is convex
Platform 13 is relative with sensor body 4, and spring 6 is sheathed on boss 13.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this reality
With new principle, it should be understood that protection domain of the present utility model is not limited to such especially statement and embodiment.
One of ordinary skill in the art these technology enlightenments can make various without departing from this practicality according to disclosed in this utility model
New other substantive various concrete deformations and combination, these deformations and combination are still in protection domain of the present utility model.
