A coupling protrusion 120 is formed on one side of the detachable main body 110 so as to engage with the connecting rod 400 and a main body rivet hole 130 is formed on the coupling protrusion 120.

The frictional force generating member 200 constitutes a cylindrical body 210 in a state where one side of the frictional force generating member 200 is open and the cylindrical body 210 is provided with a cut- (211).

The body 210 may be formed of rubber or silicone to prevent slipping when the body 210 is closely attached to the outer periphery of the fire sensor.

The body 210 is formed to protrude above the detachable body 110 to prevent the detachable body 110 from directly contacting the outer circumference of the fire detector while the body 210 is installed inside the detachable body 110.

The frictional force generating member 200 is not limited to the configuration shown in the drawing, but can be configured as shown in Fig.

Referring to FIG. 5, the fire sensor detachable device according to the present invention includes a detachable member 100, a frictional force generating member 200, a fixing member 300, and a connecting rod 400.

The structure of the attachment / detachment member 100, the fixing member 300, and the linkage 400 is the same as that of FIGS. 1 to 4, and a description thereof will be omitted. However, since the frictional force generating member 200 is configured differently Only the configuration thereof will be described.

The frictional force generating member 200 is fixed to the fixing member 300 by rivets while being positioned inside the detachable main body 100 as described with reference to FIGS. The upper end of the frictional force generating member 200 is folded to be formed of a silicone material so as to cover the upper part of the attaching / detaching body 100.

Since the upper end of the frictional force generating member 200 formed of a silicone material is folded so as to surround the upper portion of the detachable main body 100, even if it bumps against the upper end of the detachable main body 100 when the fire detector is detached, Is absorbed to prevent the fire detector from being damaged.

The frictional force generating member 200 is not limited to the configuration shown in Fig. 5, but can be implemented differently as shown in Fig.

When the fire detector is coupled to the inside of the frictional force generating member 200, a slip prevention protrusion 212 is further formed to prevent the slip phenomenon.

The slip prevention protrusion 212 may be formed thicker toward the inner side from the upper end of the frictional force generating member 200 so that the slip prevention protrusion 212 can be easily combined with a fire detector having a different size.

Referring to FIG. 7, the attaching / detaching member 100 according to the present invention has a cylindrical shape in which one side is opened, and constitutes a detachable body 110 made of silicone, rubber material or soft synthetic resin, A contact protrusion 111 integrally formed on the inner side of the detachable body 110 so as to be in close contact with the outside of the fire detector and protruding to the center is formed.

In addition, it is preferable that the inner diameter of the detachable main body 110 is formed based on the diameter of the fire detector which is most used in the market.

The fixing member 300 is formed in a cylindrical shape such that one side of the fixing member 300 is open like the attaching / detaching body 110 and is opened. And a fixed rivet hole 310 is formed in the lower end portion formed in a cylindrical shape.

The main body rivet hole 130 and the fixed rivet hole 310 are positioned on the same line and fixed by using the rivet while the fixing member 300 is installed inside the frictional force generating member 200.

The engaging cap 320 is fixed to the body 210 of the frictional force generating member 200 in a state where the engaging cap 320 is engaged with the lower portion of the fixing member 300 when the rivet is fixed by the rivet.

The coupling cap 320 may be integrally formed at a lower portion of the fixing member 300 or may be formed in a state of being removed from the configuration.

The connecting rod 00 constitutes a connecting rod body 410 having a hole (not shown) larger than the diameter of the coupling protrusion 120 so as to be coupled to the coupling protrusion 120 formed at the lower portion of the detachable body 110 A connecting rivet hole 411 is formed in the connecting body 410 in the same size corresponding to the main body rivet hole 130 formed in the coupling protrusion 120.

A fine groove 412 is formed in the longitudinal direction of the outer periphery of the connecting rod body 410 to prevent a slip of the operator's hand when the connecting rod 400 is rotated.

The connecting rod 400 includes a plurality of connecting rod bodies 410 so that the length of the connecting rod body 400 can be increased. One side of the connecting rod body 410 having a plurality of connecting rod bodies 400 is smaller than the diameter of the other connecting rod 400 ).

A first coupling hole 414 is formed in the insertion portion 413 and a second coupling hole 415 is formed in the other coupling body 410 so as to correspond to the first coupling hole 414.

The elastic body 420 is inserted into the connecting rod 400 to be easily coupled and separated by the elastic force when the connecting rod main body 410 is fixed or separated from the connecting rod body 410, .

The elastic body 420 is formed in a V shape in its entirety and is formed in a round shape such that a corner portion formed in a V shape is formed to have the same width as an inner diameter of a portion where the insertion portion 413 is formed.

A locking protrusion 421 is formed in the elastic body 420 so as to be protruded to one side of the connecting rod body 410 in a state of being coupled to the first coupling hole 414 of the insertion portion 413.

A process of separating the cover of the fire detector using the fire detector detachment apparatus of the present invention will be described.

First, the operator determines the height of the fire detector installed at the position where the fire detector is installed, and selects whether to extend the length of the fire detector detach device.

When the length is extended, the insertion portion 413 formed at one side of the connecting rod 400 is drawn into the other connecting rod 400, and the elastic body 420 protruding from the first coupling hole 414 in the pulled- The length of the connecting unit 400 is increased while the stitching protrusion 421 of the connecting unit 400 is projected to the second fitting hole 415 formed in the plurality of other connecting units 400.

In a state in which the length of the connecting rod 400 is extended, the operator places the body 210 of the frictional force generating member 200 installed inside the detachable body 110 around the outer circumference of the fire sensor installed on the ceiling.

When the body 210 is brought into close contact with the outer periphery of the fire detector, the upper part of the body 210 is expanded like a crown and is closely attached to the outer periphery of the fire detector. At this time, since the worker pushes the connecting rod 400 toward the fire sensor, the upper part of the attaching / detaching body 110 is in a state supporting the lower portion of the frictional force generating member 200.

When the worker pushes and rotates the connecting rod 400 to the side where the fire detector is installed, the fire detector cover is released from the fire detector body while the lock state is released.

In order to engage the cover of the fire detector again after the fire detector is completely inspected, the cover is placed under the fire detector main body using the connector 400 with the fire detector cover positioned above the friction generating member 200 .

When the cover is placed under the fire detector main body and the operator rotates while applying force to the fire detector main body, the protrusion formed on the cover is inserted into the groove formed in the fire detector main body and is engaged.

As described above, since the fire detector installed on the ceiling can be easily checked without using any auxiliary means such as a ladder or a work chair, it is possible to occupy a large amount of fire detectors at the same time.

Since the connection unit 400 can be extended in length as described above, it is very easy to inspect the fire detector even in a building with a high ceiling.
