The box body comprises a shoulder and a groove used for placing a sensor. Screw bolts are disposed at the bottom of the groove. An annular protrusion is disposed at the opening of the groove. Bottom installing holes are disposed on the shoulder. An annular recession and top installing holes are disposed on the box cover. The annular recession is in cooperation with the annular protrusion. Fasteners pass through the top installing holes and the bottom installing holes. The terrestrial magnetism vehicle detecting sensor housing without shielding effect has characteristics of good anti-pressure waterproof performance and a good antitheft capability.
Description
Technical field
The utility model relates to a kind of earth magnetism vehicle detecting sensor shell.
Background technology
The earth magnetism vehicle detecting sensor is embedded on the parking stall that vehicle parks, and can realize the accurate the detection whether top parks cars.Send to the base station by data are detected on the parking stall via wireless signal, can realize functions such as parking guidance.The shell of earth magnetism vehicle detecting sensor has following demand: guarantee that 1) sensor is positioned on the ground, at utmost to improve wireless signal strength; 2) have good anti-pressure ability, damaged by pressure to avoid being passed through vehicle; 3) unshielded effect is to avoid shell for the harmful effect of transmission of wireless signals; 4) have waterproof ability, damage sensor to avoid rainwater or surface gathered water; 5) possesses certain anti-theft capability, to avoid unnecessary loss.Also lack the shell that above function can be provided in the market.
Summary of the invention
In order to overcome the deficiency that the resistance to compression water resistance is relatively poor, anti-theft capability is relatively poor of existing shell, the utility model provides the unshielded earth magnetism vehicle detecting sensor shell that a kind of resistance to compression water resistance is better, anti-theft capability is good.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of unshielded earth magnetism vehicle detecting sensor shell, comprise box body and lid, described box body comprises shoulder and in order to place the groove of sensor, the bottom of described groove is provided with double-screw bolt, the open-mouth of described groove is provided with annular protrusion, has down mounting hole on the described shoulder; Described lid is provided with ring-shaped depression, has mounting hole on the described lid, and described ring-shaped depression cooperates with described annular protrusion, and securing member passes described mounting hole and the following mounting hole gone up.
Technical conceive of the present utility model is: adopts resin as the making material of shell, working sensor do not had shielding action, and cheap, and crushing resistance is good; The second, this shell comprises lid and box body two parts, and the part of box body and lid all are positioned on the ground when mounted, has guaranteed that box body inner sensor is positioned on the ground, thereby has improved wireless signal strength; Three, by the bulge-structure of lid, this shell can reach very high intensity, thereby prevents that vehicular traffic from damaging sensor by pressure; The 4th, inner box body has the projection of a circle annular, and lid has the depression of a circle annular, can realize waterproof by closely connecting.The 5th, lid and box body can fix on the ground by the mounting hole on it, by using securing member, can realize antitheft.
The beneficial effects of the utility model mainly show: can satisfy resistance to compression, waterproof, unshielded, the antitheft requirement of earth magnetism parking stall detecting sensor shell simultaneously, use cheap materials simultaneously and control cost, and economical and practical.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～Fig. 4, a kind of unshielded earth magnetism vehicle detecting sensor shell, comprise box body 1 and lid 7, described box body 1 comprises shoulder and the groove 5 in order to place sensor, the bottom of described groove 5 is provided with double-screw bolt 6, the open-mouth of described groove is provided with annular protrusion 4, has down mounting hole 2,3 on the described shoulder; Described lid 7 is provided with ring-shaped depression 10, has mounting hole 8,9 on the described lid 7, and described ring-shaped depression cooperates with described annular protrusion, and securing member passes described mounting hole and the following mounting hole gone up.
In the present embodiment, last mounting hole and following mounting hole are screw hole, and the securing member of use is special-shaped screw, and the whole resin material that adopts of shell is made, and unshielded effect can not produce the transmission of parking stall detected wireless signals and disturb, and low price, and is economical and practical.During installation, the box body partly is positioned on the ground, and part is positioned at underground; Lid then is positioned on the ground.Thereby the groove 5 interior sensors that guarantee the box body are on the ground, regard to the interference of transmission of wireless signals as far as possible with reducing.Lid 7 adopts ridge structure reaching the higher compression ability, and is difficult for ponding.The groove 5 of box body is used for placing sensor node and battery.Double-screw bolt 6 is used for sensor is fixed in the box.Annular protrusion 4 is corresponding with ring-shaped depression 10, can reach good waterproof effect.Last mounting hole 2 on the box body 1 is corresponding with the following mounting hole 8 on the lid 7, is used for the fixing of shell and ground.Last mounting hole 3 on the box body 1 is corresponding with the following mounting hole 9 on the lid 7, is used for the fixing of lid and box body.By using special-shaped screw to connect lid and box body, and connection lid and ground, this shell can possess anti-theft capability.
In the present embodiment, at first sensor node is fixed on the double-screw bolt 6 of enclosure; Cover lid 7 then, and tighten the screws fixes lid and box body, corresponding mounting hole is 3 and 9; At last whole casing is embedded in underground, and by last mounting hole 2, down mounting hole 8 is fixed on ground with shell.Be fixed on ground and can prevent stolenly, the structural design of guard shield itself is waterproof effectively, and the resin material crushing resistance is good, unshielded effect.
