Abstract

The utility model relates to a new anti-theft manhole cover which belongs to the public traffic facilities field. The manhole cover comprises a cover and a base. The cover is arranged on the base. The cover is composed of two half covers. The shaft holes which are mutually matched are arranged on one edge of two half covers along the lower part and the base edge and penetrate the shaft hole through the shaft and make the half cover and the base fixedly connected together. The bumps are respectively arranged under both ends of the combined edge of two half covers. When two half covers are combined, two bumps are buckled. The outer end face of the bump on the edge of the half cover is higher than the inner end face. The utility model is provided with an inlaid wheel shaft between each half cover and the base. The outer surface does not have the slit, which effectively prevents from being stolen. The bump is arranged on the combined edge of two half covers. When two half covers are combined, two bumps are tightly engaged to make two half covers not easily slide. The new anti-theft manhole cover reduces the noise when the vehicle presses the manhole cover. The new anti-theft manhole cover has favourable anti-theft effect, reasonable structure, easy producing and easy installation.

Description

Novel antitheft well cover

(1) technical field

The utility model relates to a kind of anti-stealing manhole cover, belongs to the public transit facility field.

(2) background technology

Existing well lid, numerous in variety, but all have various defectives.Example: the typical circular well lid since without any anti-theft measure, so thereby the stolen pedestrian's of injuring of well lid accident often appears; Circular or the square well lid to reinforcement type, it is external mostly to be a reinforcing and reinforcing place greatly, is very easily pried open by the lawless person, and anti-theft measure is undesirable; To non-casting iron well lid, adopt composite material to develop mostly, because of the no recovery value of well lid itself, thus seldom stolen, but this well lid is difficult for popularizing; Also have some to resemble internal-falling anti-stealing manhole cover, automatic opening encapsulation anti-stealing manhole cover, the personnel of needing repairing understand the unlatching knowledge of specialty or have special opener, such well lid, one side is to maintenance personal's requirement height, time one is long on the other hand, unlatching means or opener are also easily obtained by the lawless person, lose antitheft function; And on well lid, lock, then can bring great inconvenience to the maintenance personal, so this class well lid is also popularized not too easily, they only are applicable to the occasion that some are special.

(3) summary of the invention

At the deficiency that prior art exists, the utility model provides a kind of rational in infrastructure, good anti-theft effect, manufacturing is simple, easy to use and can effectively reduce the novel antitheft well cover of the noise that produced when vehicle was pressed well lid.

The utility model is achieved through the following technical solutions.

This well lid comprises well lid and base, well lid is placed on the base, it is characterized in that, well lid is made up of the two halves well lid, is equipped with the axis hole that cooperatively interacts below an edge of two halves well lid with on the base limit, passes axis hole by axis body, half well lid and base are connected and fixed, respectively be provided with projection on the two ends, edge on two halves well lid merging limit, when the two halves well lid merged, two projections fastened.

Projection outer face on the half well lid edge is higher than inner face.

The utility model is provided with two parts with well lid, and its effect is, between per half well lid and base built-in wheel shaft structure is set, and makes external surface not have the slit, has effectively prevented stolen; On the other hand, the two ends that merge the edge at the two halves well lid respectively are provided with projection, and the outer face of each projection is higher than inner face, and when well lid merged, two projections tightly meshed.Thereby make to be difficult between the well lid sliding, can effectively lower the noise that produced when vehicle was pressed well lid.Use the utlity model has good anti-theft effect, rational in infrastructure, simple, easy for installation, the low cost and other advantages of manufacturing.

Wherein, 1, half well lid, 2, half well lid edge, 3, axis hole, 4, half well lid merges the limit, and 5, base, 6, projection.

(5) specific embodiment

Embodiment: structure such as Fig. 1 one are shown in Figure 4, be made up of well lid and base 5, well lid is placed on the base, wherein, well lid is made up of two halves well lid 1, below two halves well lid edge 2 Yu on base 5 limits, be equipped with the axis hole 3 that cooperatively interacts, pass axis hole 3, half well lid 1 is connected and fixed with base 5 by axis body, on the two ends, edge on two halves well lid merging limit 4, respectively be provided with projection 6, projection 6 outer faces are higher than inner face, and when the two halves well lid merged, two projections 6 fastened.

Claims

1, novel antitheft well cover, comprise well lid and base, well lid is placed on the base, it is characterized in that, well lid is made up of the two halves well lid, below an edge of two halves well lid with on the base limit, be equipped with the axis hole that cooperatively interacts, pass axis hole by axis body, half well lid and base are connected and fixed, on the two ends, edge on two halves well lid merging limit, respectively be provided with projection, when the two halves well lid merged, two projections fastened.

2, novel antitheft well cover according to claim 1 is characterized in that, the projection outer face on the half well lid edge is higher than inner face.
