Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a locking device for a burglar-

The present invention relates to a locking device for aft detent drainage port, and more particularly, to a locking device for a drainage catch preventing aft of the drainage catch, as well as providing a stopper in the locking device so that the locking device rotates only with a special wrench member The present invention relates to a locking device for an anti-theft drainage receptacle.

In recent years, in order to solve the problem caused by the economic recession, there have been a lot of incidents where the lid of the hall lid or the grill-shaped transmissive portion which opens and closes the upper part of the collecting part are stealing. Such a loss may secondarily cause safety accidents to pedestrians and vehicles Which is a serious problem.

In order to solve such a problem, it is a reality to arrange a self-detained detacher and patrol the distance, or to connect the manhole cover to a manhole cover through a separate locking device to prevent the theft.

However, when the manhole cover is connected with a chain, it is troublesome to clean the sewer, and there is a possibility that the separate lock may be lost.

Accordingly, in the patent application No. 47443 filed by the present applicant in 2013, a technique for preventing theft by integrally providing a lock device on the drainage catch is disclosed.

FIG. 1 is a view showing a drainage catch locking device according to the related art. In the patent application No. 47443, the noncircular sectional groove 321 of the rotary member 320 is inserted into the noncircular sectional groove 311 of the locking member 310 And the rotating member 320 is rotated to unlock it.

However, the non-circular cross-sectional groove 311 of the locking member 310 is simple in shape of a triangle, so that a general person can easily open and close the same with other tools without using the rotary member 320. [

Therefore, there is an increasing demand for a drain catch lock device that can lock the locking device only with a special wrench so that the general person can not easily open and close the lock device by overcoming the unreasonableness of such a conventional drain catch device.

The upper end portion of the stopper member 61 is always positioned at the through hole 34 of the rotating body 20 by the elastic force of the spring 62 and the lower end portion of the stopper member 61 is positioned at the receiving hole 14 of the fixed body 10 Wherein one end of the spring 62 is coupled to the receiving hole 14 and the other end is coupled to the stopper member 61.

FIG. 5 is a perspective view showing a detailed structure of a lock body coupled to a transmission portion, and FIG. 6 is a plan view showing a lock body at a lower portion of the transmission portion.

Referring to the drawings, the locking body 30 is installed at one end of the transmitting portion 2, and an exposure hole 31 is formed at a position corresponding to the rotating body 20, So that the upper portion of the body 20 is exposed to the outside.

The locking body 30 further includes an extension body 30a protruding downward from the locking body 30 so that the exposure hole 31 is extended downward. The locking protrusion 21 of the rotating body 20 is pivoted with respect to the rotating shaft 11 of the fixed body 10 and inserted into the inner side surface of the inner side surface of the exposure hole 31, Respectively. A locking recess 32 is formed in the locking recess 32 so that the locking protrusion 21 is exposed to the outside so that the locking protrusion 21 can be released from the locking recess 32, Thereby allowing the body portion 30 to be unlocked from the rotating body 20.

An elastic piece 33 having a latching protrusion 33a is coupled to another inner side surface of the lock body 30 where the exposing hole 31 is formed so that the insertion wing 41 of the wrench body 40, The elastic piece 33 is elastically deformed only when the user applies a constant rotational force so that the one end of the insertion wing 41 is released from the engagement protrusion 33a.

The rotating body 20 is installed such that one side of the cylindrical rotating body 20 is surrounded by the exposing hole 31 of the extending body 30a and the other side of the rotating body 20 is fixed to the fixed body 10 so that the entire outer edge of the rotating body 20 is surrounded.

In other words, the receiving groove 13 of the fixed body 10 and the locking groove 32 of the extended body 30a are located on the same plane so that the locking protrusion 21 of the rotating body 20 is accommodated therein , And is unlocked only when the locking protrusion (21) is rotated and positioned on the uncut surface (32a).

7 is a perspective view showing the detailed structure of the wrench body.

One end of the wrench body 40 is formed with an insertion blade 41 inserted into the exposure hole 31 of the lock body 30 and one end of which is engaged with the engagement protrusion 33a of the elastic piece 33, And a handle blade 42 protruding from the other end of the wrench body 40 to allow the user to grasp the wrench body 40 easily.

A coupling groove 43 having a shape corresponding to the shape of the coupling protrusion 22 is formed on the upper surface of the wrench body 40 coupled to the upper surface of the rotary body 20. As shown in the drawing, the coupling groove 43 has a circular groove and a support protrusion 43a formed on one side of the groove to be coupled to the support groove 22a of the rotary body 20.

An insertion protrusion 44 having a length corresponding to the depth of the through hole 34 is formed at the other side of the upper surface of the wrench body 40 at a position corresponding to the through hole 34 of the rotary body 20.

A magnet or a magnetic body 45 is provided on the bottom surface of the wrench body 40 so that the protective cap member 50 is attached to the bottom surface of the wrench body 40 by magnetic force, So that the cap member 50 can be opened in the exposure hole 31. [

Referring to FIG. 8, the protection cap member 50 is provided to open and close the exposure hole 31 at the upper portion of the transmission portion 2, And the through holes 34 are prevented from being clogged by the waste.

a protective cap member 50 having a magnetic body or a magnet 51 formed on the upper surface of the protective cap member 50 and inserted into the exposure hole 31 is provided on the upper surface of the protective cap member 50, (B) is a perspective view of the protective cap member 50 viewed from the bottom, and FIG. 10 (b) is a perspective view of the protective cap member 50, So that the insertion of the protective cap member 50 is facilitated in any direction.

Hereinafter, an operation method for releasing the locking device of the anti-theft drain catch according to the present invention will be described in detail.

FIG. 9 is a view showing a state in which a permeable portion 2 made of a metal is fixed to an upper portion of a catching hole. As shown in the figure, a protective cap member 50 is inserted into an upper portion of the exposure hole 31, 40 is brought into contact with the upper surface of the protective cap member so that the protective cap member 50 is inserted and removed by magnetism so that the exposure hole 31 is exposed to the outside.

When the wrench body 40 is rotated again and one end of the wrench body 40 is inserted into the exposure hole 31, the engaging groove 43 of the wrench body 40 is engaged with the engaging protrusion 22 of the rotating body 20 , And the insertion protrusions 44 are also inserted into the through holes 34. As shown in Fig.

10 is a sectional view showing the structure in which the insertion protrusion is inserted into the through hole to move the stopper member. When the insertion protrusion 44 is inserted into the through hole 34 as shown in the figure, The end of the insertion protrusion 44 pushes the stopper member 61 to allow the stopper member 61 to move from the through hole 34 into the receiving hole 14, The stopper member 61 is received in the receiving hole 14. [

Then, when the wrench body 40 is rotated, the rotary body 20 is rotated as the support protrusion 43a of the wrench body 40 is caught by the support groove 22a, When the locking protrusion 21 is detached from the locking groove 32 of the locking body portion 30 and is positioned on the detaching surface 32a, the user opens the transmitting portion 2 to open the transmitting portion 2 to the collecting portion 1).
