Description
Technical field
The present invention relates to a kind of resistance to compression antenna structure and its assemble methods, can be widely used for wireless data transmission, especially
All kinds of instrumented data transmission such as water meter, flowmeter, calorimeter, belong to data transmission external antenna technical field.
Background technique
Currently, with the development of wireless technology, many equipment carry out data communication by wireless transmission method, thus real
The data transmission and implementation control of existing equipment.Since being carried out data transmission by wireless technology, it just be unable to do without antenna.According to day
Antenna can be divided into two kinds by the assembled relation of line and equipment, i.e. built-in antenna and two kinds of external antenna.Built-in antenna is generally answered
Used in the preferable operating condition of signal, antenna, which is not required to extraction equipment, can be realized good data communication；And external antenna is then normally applied
Signal strength is bad or uncertain operating condition, antenna can be drawn into equipment according to on-site actual situations, be placed on signal strength
Relatively good place, to guarantee the reliable transmission of device data.But in the structure of this external antenna of certain operating conditions in reality
There are some problems on border.For example, currently in order to realize data it is automatic transmit and implementing monitoring, it is general originally
Water water meter is included or subsequent configuration wireless transmission function, and these water meters are most of is mounted in tap water meter well, table
Well be generally it is brick form, top be cast iron upper cover.Signal strength is not that very well, will have a direct impact on instrument number in this way in table well
According to transmission.General settling mode is the place punching in table well side wall close to upper cover, and antenna is placed on upper outer side of lid
Subsurface；Or punched on upper lid, antenna end is stretched out into upper cover, improves signal strength.But both solutions have
Disadvantage, table well side-wall hole mode site operation work difficulty is big, time and effort consuming, it is bad that signal strength improves degree；And
It is upper to cover aperture for the method for antenna stretching upper cover since certain upper covers are that often have vehicle and row on business district or road
People pass through, be easy will stretch out antenna damage, thus cause instrumented data transmission failure, influence using.
Summary of the invention
The object of the present invention is to provide a kind of resistance to compression antenna structure and its assemble method, both can effectively solve in as table well
The bad problem of signal strength can ensure that antenna is not damaged in use again, of simple structure and low cost, assembling side
Just, the above problem present in background technique is solved.
The technical scheme is that
A kind of resistance to compression antenna includes antenna, upper cover, guide sleeve, protective case, elastic part and adjusting nut, and upper lid is equipped with through-hole,
Guide sleeve is equipped in through-hole, the perforation of guide sleeve both ends is interior to be equipped with protective case；Protective case upper end closed is barrel-like structure, protects set upper side
Higher than upper exterior surface, simultaneously above guide sleeve upper end, protective case lower end is located at the top of guide sleeve lower end；Under upper exterior surface
The guide sleeve lower end of side is equipped with external screw thread, and the upper end of adjusting nut is equipped with internal screw thread, matches with the external screw thread of guide sleeve lower end, adjusts
The bottom diameter of nut is less than the internal diameter of guide sleeve, is equipped with elastic part in guide sleeve, the upper end of elastic part acts under protective case
End, the lower end of elastic part acts on the lower end of adjusting nut；It is equipped with antenna in protective case, the connecting line of antenna is from adjusting nut
Lower end be pierced by.
The antenna is sheet, and the top of upper end in guide sleeve, chip aerial is higher than upper exterior surface, simultaneously above leading
Set upper side.
The protective case be it is barrel-shaped, antenna is the disk of sheet, and outer diameter and the protective case internal diameter of disk match.
The guide sleeve upper end and upper cover flush with outer surface or slightly above upper exterior surface.
The protective case, guide sleeve at least one be made of insulating materials.
The connecting line of the antenna is connect with transmission device.
The elastic part is spring, and when the protective case of upper cap upper surface is by external force pressure, (vehicle is rolled, pedestrian steps on
Step on), protective case is moved downward to concordant with upper cap upper surface in guide sleeve, and oppresses elastic part；After external force disappears,
Under the action of elastic part, protective case moves up in guide sleeve, is restored to home position；Antenna also returns to outside higher than upper cover
The position on surface.
The upper cover is the well lid of table well, and transmission device is located in table well, and the connecting line of antenna is connect with transmission device.
There are three types of embodiments by the present invention:
1, ladder-like annular chuck is equipped with inside the guide sleeve, the lower end outer of protective case is equipped with annular convex platform, convex annular decometer
In annular chuck, protective case is limited, guarantees that protective case will not be deviate from from above；Protective case and annular convex platform are in annular
Guide sleeve internal slide below chuck, the upper end of elastic part act on the annular convex platform of protective case lower end.
The outer surface of the guide sleeve is equipped with external screw thread, and the fastening nut positioned at upper cover lower surface is matched with external screw thread, guide sleeve
It is fixed together by fastening nut and upper cover.
2, ladder-like annular chuck is equipped with inside the guide sleeve, the lower end outer of protective case is equipped with annular convex platform, convex annular
Decometer limits protective case in annular chuck, guarantees that protective case will not be deviate from from above；Protective case and annular convex platform exist
Guide sleeve internal slide below annular chuck, the upper end of elastic part act on the annular convex platform of protective case lower end.
The top of the guide sleeve is equipped with annular outer, and the outer diameter of annular outer is greater than the through-hole internal diameter of upper cover, guide sleeve it is interior
Diameter and the through-hole internal diameter of upper cover match；Guide sleeve is stuck in the through-hole of upper cover by annular outer.
3, ladder-like annular chuck is equipped with inside the guide sleeve, the lower end of protective case is equipped with fixture nut, fixture nut bottom
