Description
Technical Field
The utility model belongs to the technical field of the air survey technique and specifically relates to a accuse oxygen appearance probe is related to.
Background
An oxygen control instrument is a device for detecting and feeding back the oxygen content in air through an oxygen sensor probe, and is commonly applied to oxygen content detection of objects such as medical ventilators, oxygen tanks, industrial production workshops and mine caves.
The oxygen control instrument in the industrial production workshop detects and adjusts the oxygen content of air and directly influences the breathing safety of personnel in the workshop, but when using in the non-dust-free workshop, oxygen control instrument probe and air contact, dust and moisture in the air directly cover on the probe electrode after long-time use, electrode head film micropore blocks, the film is comparatively fragile can not clean to the effective conducting area of electrode table head reduces, the probe can not correctly transmit the signal to oxygen control instrument host computer, must change the probe.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.
The utility model provides an oxygen control instrument probe, includes the probe, wherein, the probe upper end is equipped with spliced pole, probe terminal box, first hickey has been attacked to spliced pole upper end surface, the second hickey has been attacked to the lower extreme surface, and the spliced pole middle part is from last down running through there being cylindrical through-hole, it has the signal transmission mouth to open on the probe terminal box, probe terminal box lower extreme is opened there is the first screw with the first hickey matched with in spliced pole upper end, and the probe passes the cylindrical through-hole and the probe terminal box of spliced pole and is connected, the spliced pole lower extreme is connected with the filtering cover, the inside second screw with spliced pole lower extreme second hickey complex that is equipped with in filtering cover upper end, the filtering cover covers the probe, and open on the surface has the aperture.
Compared with the prior art, the beneficial effects of the utility model are that: through covering the filtering cover outside the probe, effectively avoid in the air material such as moisture, dust to cover on the probe, the filtering cover is connected for dismantling with the spliced pole, can lift off when the filtering cover long time is used and carry out the air gun cleanness of blowing, effectively prolongs the life of probe.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an enlarged schematic view of the connecting column structure.
In the figure: the probe comprises a probe-1, a connecting column-2, a first threaded interface-21, a second threaded interface-22, a cylindrical through hole-23, a probe junction box-3, a first screw hole-31, a signal transmission port-4, a filtering cover-5, a second screw hole-51, a paper filter screen-52 and a stainless steel sleeve-53.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, in the embodiment of the present invention, an oxygen control instrument probe includes a probe 1, wherein the upper end of the probe 1 is provided with a connection column 2 and a probe connection box 3, the upper end surface of the connection column 2 is tapped with a first screw interface 21, the lower end surface is tapped with a second screw interface 22, the middle part of the connection column 2 penetrates through a cylindrical through hole 23 from top to bottom, the upper end of the probe connection box 3 is provided with a signal transmission port 4, the lower end of the probe connection box 3 is provided with a first screw hole 31 matched with the first screw interface 21 at the upper end of the connection column 2, the probe 1 penetrates through the cylindrical through hole 23 of the connection column 2 to be connected with the probe connection box 3, the probe 1 converts an oxygen signal into an electrical signal through the probe connection box 3, and the probe connection box 3 is connected with an oxygen control instrument host through the signal transmission port;
the lower extreme of spliced pole 2 is equipped with filtering cover 5, filtering cover 5 upper end inside is equipped with the second screw 51 with spliced pole 2 lower extreme second hickey 22 complex, filtering cover 5 covers probe 1, and the surface is opened there is the aperture. Through covering filtering cover 5 outside probe 1, effectively avoid in the air material such as moisture, dust to cover on probe 1, filtering cover 5 is connected for dismantling with spliced pole 2, can lift off when filtering cover 5 uses for a long time and use special air gun clean of blowing, effectively prolongs the life of probe.
