Description

Steel fibre composite material anti-stealing manhole cover

Technical field

The utility model relates to a kind of anti-theft device that is used for the underground pipeline well lid.

Background technology

At present, modern urban construction has driven the high speed development of underground pipeline, and underground pipeline generally is used for the provided underground of communication apparatus such as optical cable, optical fiber, can establish a well head every a segment distance, be equipped with well lid on the well head, be convenient to the detection of communicating interrupt maintenance and circuit like this.But such well lid ubiquity the problem of easily being stolen.Existing well lid is generally without any anti-theft device, only need from well lid through hole one sled, just can pry open well lid easily, stay the well head on road surface, this just makes vehicle, the pedestrian of road surface walking, exist the danger under the back drop, because well lid is stolen, subterranean cable, optical fiber are subjected to wind and rain, artificial invasion and attack, usually cause communicating interrupt, and whole piece optical cable, optical fiber are easily aging, and application life is short.

Summary of the invention

The purpose of this utility model is intended to overcome the deficiency that above-mentioned prior art exists, and a kind of novel anti-stealing manhole cover is provided.The utility model comprises movable latch fitting on well lid, the well lid, lockaid gun, fixedly snap close is formed.When mounted, be embedded with one section steel plate, a side of steel plate and the anchor bar welding that is embedded in the well head edge concrete, the opposite side of steel plate and fixedly snap close welding at well head.Movable latch fitting places the below of well lid, and near the pre-buried one section band steel in endosexine, the built-in anchor bar of a side of band steel and well lid welds below well lid, the opposite side of band steel and the welding of movable latch fitting, and movable latch fitting is buckled in the pin button automatically when covering well lid.When opening well lid, have the through hole of the lockaid gun of magnetic from the well lid reservation, utilize the characteristic of magnet, inhale and open movable snap close, both can directly mention well lid, perhaps can utilize the steel plate on the rotation lockaid gun, come the separate activities latch fitting to reach the purpose of opening well lid.

The beneficial effects of the utility model are, well lid and well head have adopted movable latch fitting directly to be buckled in fixedly snap close, fastness strengthens, and does not have specific lockaid gun just can't open well lid, has solved stolen this key issue of well lid, more help the constructor and when construction, open well lid quickly, increase work efficiency, and whole device technique is simple, cost is low, can put into production energetically, promote the use of for a long time.

The specific embodiment

In order to understand the specific embodiment of the present utility model better, below in conjunction with description of drawings the utility model is specifically implemented demonstration example and is further elaborated:

Embodiment 1, and as shown in fig. 1, the utility model is respectively to be provided with movable lock ring 2 in the both sides of well lid A both sides through hole 1, and the well head edge is provided with fixedly snap close 4.As shown in Figure 3, weld near the pre-buried one section band steel 5 in endosexine by lock ring seat 3 and well lid A below at the two ends of movable lock ring 2, built-in anchor bar 9 welding of the opposite side of band steel 5 and well lid, perforation 6 is arranged on the lock ring seat 3, movable lock ring 2 two ends are interspersed in perforation 6, described perforation 6 leaves one section free gap after movable lock ring 2 interts, the lock ring 2 that innervates can freely swing.As shown in Figure 2, fixedly snap close 4 steel plate 7 welding pre-buried, a side of steel plate and the anchor bar welding that is embedded in the well head edge concrete with the well head surface.When covering well lid A, movable lock ring 2 vertically downward, fixedly snap close 4 passes movable lock ring 2 and fastens movable lock ring 2, well lid just is difficult for opening like this, described movable lock ring 2 and fixedly snap close 4 shapes as shown in FIG., when opening well lid, magnetic lockaid gun B inserts through hole 1, utilize the magnetic force of the magnet generation of lockaid gun B head band, inhale and open movable lock ring 2, both can directly mention well lid A.

Embodiment 2, and as Fig. 4, shown in Figure 5, the difference of present embodiment and embodiment 1 is to be, on well lid A both sides through hole 1 movable latch fitting 12 are set, and movable latch fitting 12 comprises chock 13, bar axle 15, buckle 16 compositions.Have storing activity latch fitting chock 13 grooves 14 at the through hole 1 surperficial position of well lid A, movable latch fitting chock 13 welding bars axles 15, bar axle 15 place in the through hole 1 and downwards and extend, the other end of bar axle 15 and buckle 16 welding.The well head edge is provided with fixedly snap close 17, fixedly snap close 17 steel plate 18 welding pre-buried with the well head surface, a side of steel plate and anchor bar 19 welding that are embedded in the well head edge concrete.When covering well lid A, earlier movable latch fitting 12 is risen to the well lid surface, rotation chock 13, driving buckle 16 by bar axle 15 makes it depart from fixedly snap close 17, when well lid covers well head, will rotate chock 13 and put into well lid groove 14, buckle on the movable latch fitting 12 16 and fixing snap close 17 the same sides, if upwards promote well lid, then buckle 16 will block fixedly snap close 17.When opening well lid, as shown in Figure 3, utilize the magnet 20 on the lockaid gun B to contact with movable latch fitting chock 13, utilize the magnetic force of the magnet generation of lockaid gun B head band, movable latch fitting 12 is opened in suction, rotation chock 13 drives buckle 16 by bar axle 15 and makes it depart from fixedly snap close 17, both can directly mention well lid A.

Claims (2)

1, a kind of steel fibre composite material anti-stealing manhole cover, comprise movable latch fitting on well lid, the well lid, lockaid gun, fixedly snap close is formed, it is characterized in that: fixedly snap close is welded on one section pre-buried steel plate of well head, one side of steel plate and the anchor bar welding that is embedded in the well head edge concrete, movable latch fitting is welded on one section pre-buried band steel of the below of well lid, movable latch fitting is buckled in the pin button automatically when covering well lid.
