Abstract

The utility model discloses an anti-theft inspection well cover, which comprises the well cover and a locking mechanism on the back surface of the well cover, wherein the locking mechanism consists of a locking body and lock levers arranged on the two sides of the locking body; the locking body is fixed on the well cover; a lock core is arranged in the locking body and is interlocked with the lock levers through a connecting device; the lock core is provided with a lock hole in an abnormal structure; and a key matched with the abnormal structure of the lock hole is embedded into the lock hole and is used for opening and closing the locking mechanism. The locking mechanism of the anti-theft inspection well cover has convenient operation and good anti-theft function because the locking mechanism can be opened by a special key, and reduces accidents and unnecessary material damage caused by the loss of the well cover.

Description

A kind of anti-stealing manhole cover

Technical field

The utility model relates to the urban operating mechanism field, is a kind of anti-stealing manhole cover specifically.

Background technology

Inspection shaft is the provided underground communication cable, electric wire, pipe-line such as coal gas and plumbing, be used for a kind of urban operating mechanism that personnel pass in and out and are communicated with ground for ease of maintenance installing in a determining deviation, the maintenance of pipe-line and maintenance are all more convenient like this, can not influence the appearance of the city yet, but traditional Cover of inspection well does not have locking device, well lid just installs the back as a kind of safety device at inspection shaft, prevent that Pedestrians and vehicles from falling into, but automobile crosses the road surface is vibrated, be easy to make well lid to jump out of inspection shaft, and, the stolen phenomenon of well lid also often takes place, although municipal personnel take multiple measure to make up, be included in lockset is set on the well lid, but actual effect is unsatisfactory, and most of lockset ordinary person also can open, and therefore can't fundamentally refuse to steal phenomenon.

Summary of the invention

Problem to be solved in the utility model is exactly at the easy stolen shortcoming of existing Cover of inspection well, a kind of simple in structure, easy to operate anti-stealing manhole cover is provided, reach the purpose that prevents that well lid is stolen, minimizing is lost because of well lid and is had an accident and unnecessary material damage.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of anti-stealing manhole cover, comprise well lid and be located at the retaining mechanism at the well lid back side, it is characterized in that: this retaining mechanism is made up of lock body and the locking bar that is located at the lock body both sides, lock body is fixed on the well lid, is provided with lock core in the lock body, and lock core is by linkage and locking bar interlock, lock core is provided with the lockhole of a polymorphic structure, and lockhole is embedded in the key that the polymorphic structure with lockhole matches and is used to open and close retaining mechanism.

Further, described lock core is the driven gear of active switching on lock body, be provided with the lockhole of a dentalation at the driven gear center, described key comprises the driving gear that is meshed with dentalation in the lockhole and is connected rotating shaft on the driving gear that well lid is provided with and is used for the keyhole that key penetrates.

Further, described linkage comprise be located at driven gear up and down both sides and with the driven tooth bar of driven gear engagement, one end clamping contiguous block of driven tooth bar, contiguous block is fixedlyed connected with locking bar, the driven gear rotation drives upper and lower two driven tooth bars and produces relative motion, realizes locking or unlatching between locking bar and inspection shaft then.

Further, well lid shown in is provided with the supporting base that the guiding locking bar slides on the locking bar direction of motion.

Of the present utility modelly be a little: by on well lid, setting up retaining mechanism, make well lid can be fixed on the inspection shaft, can not jump out of; Retaining mechanism of the present utility model is easy to operate, need special-purpose key just can open, so theftproof performance is good, and minimizing is lost because of well lid and had an accident and unnecessary material damage.

Description of drawings

Below in conjunction with accompanying drawing to the utility model left side further instruction:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the enlarged drawing of retaining mechanism among Fig. 1;

Fig. 3 is a practical application structural representation of the present utility model.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model provides a kind of anti-stealing manhole cover, comprise well lid 1 and be located at the retaining mechanism at well lid 1 back side, this retaining mechanism is made up of lock body 2 and the locking bar 3 that is located at lock body 2 both sides, lock body 2 is fixed on the well lid 1, is provided with lock core in the lock body 2, and lock core 21 is by linkage and locking bar 3 interlocks, lock core is provided with the lockhole of a polymorphic structure, and lockhole is embedded in the key that the polymorphic structure with lockhole matches and is used to open and close retaining mechanism.

As a kind of preferred version: lock core is the driven gear 21 of active switching on lock body 2, be provided with the lockhole of a dentalation at driven gear 21 centers, described key comprises the driving gear 5 that is meshed with dentalation in the lockhole and is connected rotating shaft 51 on the driving gear 5 that well lid 1 is provided with and is used for the keyhole 11 that key penetrates.Linkage comprise be located at driven gear about in the of 21 both sides and with the driven tooth bar 22 of driven gear 21 engagement, one end clamping contiguous block 23 of driven tooth bar 22, contiguous block 23 is bolted to connection with locking bar 3, driven gear 21 rotations drive upper and lower two driven tooth bars 22 and produce relative motion, realize locking or unlatching between locking bar 3 and inspection shaft then.Well lid 1 is provided with the supporting base 4 that guiding locking bar 3 slides on locking bar 3 directions of motion, supporting base 4 can guide locking bar 3 to slide, and has also played the effect that locking bar 3 is supported simultaneously.

After installing well lid 1, the municipal administration personnel make key are moved in the keyhole, to be engaged with in the teeth groove in driving gear 5 embedding driven gears 21 lockholes on the key, rotating shaft 51, make driving gear 5 rotations drive driven gear 21, then drive the driven tooth bar 22 be located at driven gear 21 upper and lower both sides and produce relative motions, locking bar 3 slips in the groove on the inspection shaft borehole wall with this fixing well lid.
