The present invention relates to a manhole cover anti-theft structure, which in particular provides a prevention structure for theft and loss prevention in the manhole cover to protect the manhole cover from theft and loss to minimize the physical and human damage caused by the loss of the manhole cover The present invention relates to a manhole cover anti-theft structure used for sewers, roads, rivers, and environmental facilities.

In general, a manhole is a general term for a facility that allows people to enter and exit for maintenance and repair of various pipelines installed underground. Such a manhole is a channel for supplying various sewage, living and industrial water, or a pipeline for various telecommunications. It is installed at regular intervals in the middle.

Such a manhole consists of a manhole body formed with an entrance, a manhole cover seated on top of the manhole body, and a manhole cover seated on the manhole cover to seal the entrance and exposed to the ground at the same time. .

Here, the conventional manhole cover is usually manufactured using a cast iron material to secure sufficient support rigidity and compressive strength and to secure its own weight. However, the manhole cover that is generally installed is installed on the upper side of the manhole as a simple cover type, so that anyone who is not an operator or a manager can easily open it with a hook or pickaxe without any special equipment. Recently, frequent theft accidents occur due to the rise of steel raw materials.

In particular, if the manhole cover is lost due to the above reasons, underground facilities are exposed to the ground, which causes difficulties in maintenance, and if the manhole is placed on the road, the car may fall into this manhole and lead to a large rollover accident. In addition, there may be a fall accident due to pedestrian carelessness, there is a problem that the risk of safety accident is very large.

The present invention has been devised to solve the above problems, by providing an anti-theft structure for preventing theft and loss in the manhole cover and the manhole cover to reduce physical and human damage caused by theft and loss of the manhole cover and The aim is to provide an anti-theft structure for manhole cover used in sewers, roads, rivers, and environmental facilities that can prevent the risk of safety accidents caused by theft.

In order to achieve the above object, the present invention, buried in the ground is connected to the rain pipe to the side wall and the upper side is formed with a manhole, the upper part of the manhole is coupled to the upper ring of the manhole cover for mounting the manhole cover protruding upward A manhole structure comprising a manhole cover and a manhole cover which is covered on the manhole cover and formed in the manhole, and has a manhole cover protruding downwardly from the outer circumference thereof. A through hole drilled at equal intervals along the outer circumference, and a through hole communicated with the manhole cover on the manhole cover so that the through hole communicates with each other, and the other one facing the through hole. An elongated rod-shaped fastening rod for coupling the manhole cover to the manhole cover while simultaneously penetrating the through hole, and So that it can not be detached for the conjunctival optionally provides a manhole cover anti-theft structure, it characterized in that it comprises a locking device is fastened to the fastening bar a front portion thereof.

Here, the fastening rod applied to the present invention is made of a configuration in which the stopping jaw is vertically formed at one end of the fastening rod and the locking device hole for fastening the locking device is formed at the other end.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view for showing the overall configuration of the manhole cover anti-theft structure according to the present invention, Figure 2 is a combined perspective view showing an image formation state of the present invention according to FIG.

Referring to FIG. 1, the manhole cover anti-theft structure of the present invention includes a through hole 22 and 32 formed in the manhole cover 2 and the manhole cover 3, and the manhole cover 3 and the manhole cover 2. The fastening rod 4 penetrates through the through holes 22 and 32 at the same time, and the locking device 5 for preventing the fastening of the fastening rod 4 is formed.

A plurality of through holes 22 and 32 are formed on the outer circumference of the seat frame 20 protruding upward from the manhole cover 2 and the outer circumference of the side wall 30 protruding downward on the outer periphery of the manhole cover 3. do. The manhole cover 2 is fixedly installed through an anchor bolt (not shown) around the entrance 10 opened in the upper part of the manhole 1, and the manhole cover 3 covers the manhole cover 2 thereon. It is seated to seal the entrance 10 formed in the manhole. Of course, a plurality of drainage holes (not shown) are perforated in the manhole cover 3 for drainage.

The fastening rod 4 is formed of the through holes communicated with the manhole cover 3 on the manhole cover 2 so that the through holes 22 and 32 formed in the manhole cover 2 and the manhole cover 3 communicate with each other. The manhole cover 2 and the manhole cover 3 are coupled while simultaneously penetrating one through hole and the other through hole facing the through hole. The fastening rod 4 has an elongated rod shape and the stopper jaw 40 is vertically formed at one end thereof, and the locking device hole 42 for fastening the locking device 5 is formed at the other end thereof.

Here, the stopping jaw 40 prevents the fastening rod 4 from penetrating the through holes 22 and 32 completely, and when the locking device is fastened to the locking device hole at the other end of the fastening rod. Together, the fastening rod serves to prevent detachment. The stopping jaw 40 needs only to be larger than the width of the through holes 22 and 32.

The locking device 5 is fastened to the locking device hole 42 at the tip of the fastening rod 4 passing through the through holes 22 and 32. As the locking device 5, a known general lock is suitable, and it may be preferable to apply a dial lock that does not require a key among the locks.

The present invention made of the configuration as described above is fastened as shown in Figure 2 to prevent theft and loss of the manhole cover from the manhole.

Looking at the fastening process briefly, the manhole cover 3 is first seated on the manhole cover 2 so as to cover the manhole cover 2, but the through hole 22 and the manhole formed in the outer circumference of the manhole cover seat frame 20 Through holes 32 formed in the outer circumference of the lid 3 are matched to communicate with each other.

Then, the fastening rod 4 is inserted into one of the through holes, and then pushed into the other end of the fastening rod 4 having the locking device hole 42 formed therein. Allow it to pass at the same time.

Finally, when the locking device 5 is inserted into the locking device hole 42 of the tip of the fastening rod 4 protruding to the outside after passing through the through hole, the fastening is simply completed.

According to the present invention to be fastened as described above, the manhole cover 3 is fastened to the manhole cover 2 through the fastening rod 4 and the fastening rod 4 is dismantled due to the locking device 5. The restraint is maintained unless it is. Therefore, the manhole cover 3 is not detached from the manhole cover 2 arbitrarily, and as a result, the manhole cover 3 can be prevented from being cut off. In addition, the vehicle rollover accident and pedestrian fall accident due to the detachment of the manhole cover can be blocked in advance.

As described above, according to the manhole cover anti-theft structure of the present invention, since the manhole cover is not randomly released from the manhole unless the locking device is released, the manhole cover can be safely protected from theft, and the water caused by the manhole cover theft Eliminate enemy losses. In addition, there is an effect such that it is possible to prevent vehicle and pedestrian safety accidents that may occur when the manhole entrance is opened due to theft of the manhole cover.

Although the present invention has been illustrated and described with reference to specific embodiments, it is understood that the present invention can be variously modified and changed without departing from the spirit or the field of the present invention provided by the following utility model registration claims. It will be appreciated that those skilled in the art can easily know.
