Description

Well lid electronic tag

Technical Field

The utility model belongs to the technical field of electronic tags, and relates to a well lid electronic tag.

Background

The well lid is a closed object which is led to the top of an access of an underground facility, and the well lid is required to be installed in places where public facilities such as tap water, telecommunication, electric power, gas, heat, fire protection, sanitation and the like are installed. In order to obtain the related information of the cable below the well lid, such as the cable specification, the cable trend, the operator affiliation, etc., an electronic tag or a visual tag is usually installed on the well lid or a floor tile beside the well lid or a cement road.

For example, the chinese patent discloses a manhole cover type electronic tag [ No. CN209514676U ], comprising a main body and a connecting rod, wherein the main body comprises a tray body and a connecting column arranged at the lower end of the tray body, the lower end of the connecting column is provided with a plurality of petal portions axially split by a separating groove; the petal-shaped connecting plate is characterized by further comprising a connecting hole, the connecting hole extends from the upper end of the plate body to the upper end of the separation groove on the connecting column, the connecting rod is arranged in the connecting hole in a pluggable mode, the lower end of the connecting rod extends out of the lower end of the connecting column, and the petal part forms an enlarged part under the action of the connecting rod.

When the connecting rod is inserted into the connecting hole, the connecting rod extrudes the side wall of the connecting hole, so that the connecting hole is extruded and deformed at the position provided with the positioning groove, and the deformed convex part is embedded into the positioning groove, thereby playing the role of fixing the connecting rod. However, this structure has the following problems: 1. the main body is made of engineering plastics, so that the connecting rod cannot cause extrusion deformation to the connecting hole when inserted, and the fixing effect is poor; 2. the distance from the enlarged part below the well lid to the upper surface of the main body is fixed, so that the well lid can only adapt to the well lid with a specific thickness, and the applicability is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a well lid electronic tag with a good fixing effect aiming at the problems in the prior art.

The purpose of the utility model can be realized by the following technical scheme:

well lid electronic tags locates the upper cover on the base and locates the electronic tags body of upper cover downside including base, lid, the connecting cylinder that downwardly extending has on the base, the lower extreme of connecting cylinder has a plurality of circumference and distributes and axially extended fluting, forms the expanding lamella between the fluting of two adjacencies, on cover to have and to insert the connecting cylinder hole and can be with the outside expanded insertion post of expanding lamella, it is used for the restriction to insert the stopping structure that the post that inserts that targets in place withdraws from to be equipped with between post and the connecting cylinder to insert.

The inner hole of the connecting cylinder is a through hole, and the upper end of the connecting cylinder penetrates through the base. During the installation, insert the other ceramic tile of well lid or the subaerial mounting hole of cement earlier in, on the upper cover that will be equipped with the electronic tags body is connected to the base afterwards, insert the hole of connecting cylinder to the insert post promptly, insert the post and outwards expand the lamella of opening when inserting the post and put in place, a plurality of petals of opening and mounting hole tight fit that expand realize the axial fixity of base. Due to the retaining structure, the insertion column which is inserted in place can be effectively prevented from withdrawing from the inner hole of the connecting cylinder, and the fixing effect is good. After the connection is good, the expansion valve is located in the mounting hole, and the expansion valve is applicable to mounting holes with different depths and wide in application range.
