Fire detectors that are generally installed on ceilings, etc. consist of a sensing head that houses the sensor body, and a base. By making it removable, only the sensing head can be easily removed for maintenance, inspection, replacement, etc. However, when a fire detector is installed at a high place such as a ceiling surface, it is difficult to reach it directly, so various attachment/detachment devices having longer operating rods have been proposed and implemented. Most conventional attachment/detachment devices of this type have a holder that houses the sensing head at the tip of a long operating rod, and an elastic member is provided around the inner surface of this holder to wrap around the sensing head. The frictional resistance was used to make it possible to attach and detach the device. However, such attachment/detachment operations based on frictional resistance are difficult because the sensing head is not securely held in the holder, and furthermore, the sensing head cannot be easily separated from the holder after attachment/detachment is completed, making it difficult to quickly attach/detach. It was hot.

The attachment/detachment device according to this invention will be explained in detail below based on the drawings. Fig. 1 is a longitudinal cross-sectional view showing an embodiment of the attachment/detachment device according to this invention, which includes a container-shaped holder H for accommodating a sensing head, It is connected to the bottom of this holder H and consists of an operating rod B having an appropriate length, and on the inner peripheral surface of the holder H,
A protruding piece T, which is biased by a spring member S or the like, is provided so as to be able to protrude and retract at a position opposite to the opening through which heat or smoke from the sensing head enters. The shape of this protruding piece T is such that its tip is rounded in the vertical direction, as shown in the perspective view of Figure 2.
t 1 , it is easy to move forward and backward along the surface of the sensing head when installing and removing the sensing head. In addition, the tip has a non-rounded surface t2 in the left and right direction, so when the sensing head is rotated relative to the base and removed, it engages with the opening of the sensing head and is inserted into the holder H. It prevents the rotation of. In this embodiment, an L-shaped leaf spring is used as the spring material S and is fixed to the bottom of the holder H with a screw N, but it is possible to bias the protruding piece T with other members such as a spring. be.

FIG. 3 shows the state of use of the attachment/detachment device of this invention constructed as described above. When it is inserted into the sensor head and rotated slightly in the left and right directions, the protruding piece T falls into the opening O of the sensing head DH, preventing rotation and fixing it. In this way, the sensing head
When the DH is placed on the base DB and rotated, the terminal HT on the sensing head DH side is engaged with the terminal receiving part BT on the base DB side and fixed. When the operating rod B is pulled in this state, the protruding piece T moves back and forth along the surface of the sensing head DH, and the holder H is easily removed from the sensing head DH. As described above, the work of installing the sensing head DH can be carried out easily and quickly. Also, when removing the sensing head DH from the base DB, apply the holder H to the sensing head DH on the ceiling C and rotate it slightly in the left and right direction in the same way as when installing it. Fall sensing head
Ensure DH is retained. When rotated further, the terminal HT on the sensing head DH side will be connected to the terminal receptacle on the base DB side.
It can be removed from the BT and the sensing head DH can be completely removed from the base DB. By pulling out the sensing head DH inside the holder H, the protruding piece T moves back and forth along the surface of the sensing head DH, so that it can be easily removed.

As described above, the attachment/detachment device of this invention facilitates the attachment and detachment of the sensing head DH to and from the holder H and securely holds it within the holder H, and allows quick attachment and detachment to the base DB. The work was realized. Note that the protruding piece T is the sensing head DH.
If a material with hardness equivalent to that of the material used is used, the sensing head DH will not be damaged during attachment/detachment work.
