Description

Fire hydrant structure

A fire hydrant structure, especially installed on a door panel, to prevent it from being deformed by heat and to prevent the spread of dense smoke and fire during a fire.

In recent years, due to the frequent fire incidents in public places, workplaces, and even ordinary homes, people’s awareness of fire protection has risen. In order to slow down the spread of fire during a fire, people have begun to purchase fire protection equipment or install fire protection equipment. During a fire, the doors of public places, workplaces, and even ordinary homes are easily deformed due to heat. Thick smoke and fire will enter through the deformed door cracks, affecting people's lives.

Therefore, in order to prevent the door from being deformed due to heat, many doors will be equipped with fire hydrants to deal with a fire. The fire hydrant can fix the door to prevent heat deformation.

Please refer to Taiwan Patent No. I634257 "Positioning Fire Hydrant", as shown in the first to third pictures, when the fusible fastener is melted by heat, the latch can be unlocked, and the elastic element pushes against the latch to protrude The opening of the bottom plate can be automatically locked when heated to prevent the door from deforming to prevent the spread of dense smoke and fire.

However, although the above structure can achieve the effect of automatic locking when exposed to heat, the fusible fastener is locked at the narrow mouth, and the external thread of the fusible fastener must conduct heat through the internal thread of the cylinder. It can be melted, and the latch cannot be unlocked when the fire spreads, so as to automatically lock when heated to prevent the door from deforming to prevent the spread of smoke and fire. How to unlock the fire hydrant when the fire spreads to prevent the door from being locked Thermal deformation has become a problem that all businesses want to improve.

In view of the above description of the prior art, this creation provides a fire hydrant structure that can be released when it is heated and melted, preventing the door from deforming to block the spread of dense smoke and fire, and improving the conventional wisdom that cannot be unlocked when the fire spreads. Prevent the problem of door deformation.

To achieve the above objective, the present invention provides a fire hydrant structure, including: a pipe body with a first opening connected to the pipe body at one end; an elastic element located in the pipe body, the elastic element is compressed by force, the One end of the elastic element abuts against the inner wall opposite to the end of the first opening; a bolt, one end of which abuts against the elastic element, and the other end of the bolt does not penetrate the inner wall of the first opening; and a The fusible stopper is located in the first opening, and the bolt abuts against the fusible stopper; wherein, the fusible stopper covers the stopper, and the fusible stopper meets When thermally melted, the elastic element can rebound and push the bolt to protrude toward the first opening of the tube body.

Please refer to the first to third figures, this creation provides a fire hydrant structure, including: a pipe body 1 with a first opening 11 connected to the pipe body 1 at one end; an elastic element 2 located in the pipe In the body 1, the elastic element 2 is compressed by force, and one end of the elastic element 2 abuts against the inner wall opposite to the end of the first opening 1; a bolt 3, one end of which abuts against the elastic element 2, the bolt The other end of the member 3 does not penetrate the inner wall of the first opening 11; and a fusible stopper 4 located in the first opening 11, the bolt 3 abuts against the fusible stopper 4 Wherein, the fusible stop 4 shields the bolt 3, when the fusible stop 4 melts when heated, the elastic element 2 can rebound and push the bolt 3 toward the tube 1 The first opening 11 protrudes.

It can be seen from the above that this creation is a fire hydrant structure, which is composed of a pipe body 1, an elastic element 2, a bolt 3, and 4 fusible stoppers. The elastic element 2 and the bolt are assembled in sequence during assembly. 3 Put one end of the first opening 11 into the inside of the tube 1 and use the fusible stop 4 to cover the bolt 3, the fusible stop 4 will be released when it is heated and melted, and the elastic element 2 will push against the bolt Piece 3 makes the bolt piece 3 protrude from the first opening 11 to prevent the door from being deformed to prevent the spread of dense smoke and fire, and to improve the problem that the conventional door cannot be unlocked when the fire spreads and prevent the door from being deformed.

In order to better understand the purpose and effect of this creation, this creation has a first embodiment and a second embodiment. The following first embodiment of this creation takes the pipe body 1 installed in the door panel 5 as an example.

Please refer to the first to sixth figures, the tube body 1 of the first embodiment of the invention has a second opening 12 opposite to the first opening 11, and one end of the elastic element 2 abuts against the inner wall of the second opening 12, as As shown in the fourth figure, compared with the prior art, the fusible stopper 4 located at the first opening 11 is aligned with the side of the door panel 5. The fusible stopper 4 has a smaller volume and costs more for melting The time is relatively short. The corresponding side of the door panel 5 is provided with a recess 51. At this time, the elastic element 2 is in a compressed state, and since the fusible stop 4 is located in the first opening 11, when the fusible stop When the stop 4 is heated and melted into a liquid state, the bolt 3 can be unlocked at the moment, and the elastic element 2 compressed by the force can push the bolt 3 to protrude out of the door panel 5 and protrude to the corresponding concave hole of the door panel 5. Within 51.

The first embodiment of this creation is similar to the second embodiment, and the difference is that the second embodiment uses the tube body 1 and the base 6 to be combined and installed on the door panel 5.

Please refer to the seventh to the ninth figures, the second embodiment of the present creation further includes a base 6, the tube body 1 is assembled with the base 6, the base 6 has a connecting hole 61, and the first opening 1 communicates with the connecting hole 61. The base 6 includes a heat conduction surface 62 and a back surface 63 opposite to the heat conduction surface 62. As shown in the seventh and eighth figures, the fusible stop 4 is located on the inner wall of the first opening 11, and the fusible stop The piece 4 is aligned with the heat conducting surface 62, the tube body 1 protrudes toward the back surface 63, and the base 6 includes a plurality of positioning holes 64 arranged at intervals, and the plurality of positioning holes 64 are located on both sides of the connecting hole 61, such as the ninth As shown in the figure, each positioning hole 64 is locked with a screw 7 from the heat conducting surface 62 toward the back 63, so that the pipe body 1 can be more stable when installed in the door panel 5, and the heat conducting surface 62 of the base 6 can When a fire occurs, heat is conducted to the fusible stopper 4 to accelerate the melting speed of the fusible stopper 4.

It can be seen from the above that the first embodiment and the second embodiment of this creation are both installed in the door panel 5 with the tube body 1, and the fusible stop 4 is located in the first opening 11 and is flush with the side of the door panel 5. The fusible stop 4 is melted by the heat, so that the resilient element 2 that is resilient is pushed against the bolt 3, so that the bolt 3 protrudes from the first opening 11 and protrudes into the concave hole 51 corresponding to the door panel 5. , To improve the problem that the conventional door cannot be unlocked when the fire spreads to prevent the door from deforming.
