Technical Field

The invention relates to the technical field of disaster prevention and self-rescue equipment, in particular to a locking mechanism for an earthquake safety podium.

Background

Earthquake, also called earthquake and earth vibration, is a natural phenomenon that the earth's crust will generate earthquake waves during the vibration caused by the process of releasing energy rapidly. The mutual extrusion and collision between the plates on the earth cause the dislocation and the fracture of the plate edges and the plate interiors, which is the main reason of the earthquake.

The earthquake often causes serious casualties, can cause fire, flood, toxic gas leakage, bacterial and radioactive substance diffusion, and can also cause secondary disasters such as tsunami, landslide, collapse, ground cracks and the like.

The current state of technology cannot predict the arrival of an earthquake, and the earthquake cannot be predicted for a long time in the future. The examples of the successful prediction of the earthquake are basically coincidental. For earthquakes, what we should do is to improve the earthquake-resistant grade of a building and make a defense, but in the prior art, the building lacks the capability of resisting a strong earthquake, so that an auxiliary self-rescue device is commonly used, the situation that people cannot escape from the building and are buried in a living mode when the earthquake happens is avoided, but the locking mechanism of the safety door in the conventional safety cabin is simple, and the safety door is easy to open due to external force, so that safety accidents are caused.

the utility model provides an earthquake is locking mechanism for safe podium, includes the safety cabin and articulates the emergency exit in safety cabin one side, the emergency exit passes through to articulate between reset spring and the safety cabin, be equipped with the draw-in groove with the emergency exit adaptation on the safety cabin, the draw-in groove is transversal personally submits the character cut in bas-relief shape, and the welding of bottom has the uide pin, the blind hole with the uide pin adaptation is seted up to the safety cabin bottom, the welding of draw-in groove both ends has the voussoir, safety cabin both sides bottom is equipped with the stool, stool one side is equipped with the fixture block that corresponds with the voussoir, the stool downside is fixed with the stool foot, the observation window has been seted up to safety cabin one side, the bleeder vent has been seted up to the safety cabin opposite side.

Preferably, the safety doors are provided with two groups and are respectively arranged on two sides of the safety cabin.

Preferably, the clamping groove is movably connected with the safety cabin, and the clamping groove is in sliding contact with the safety door.

Preferably, the bottom of the safety cabin is provided with a sliding hole matched with the clamping groove, and the blind hole is formed in the bottom of the sliding hole.

Preferably, sliding contact between uide pin and the blind hole, uide pin and blind hole all are equipped with the multiunit, evenly distributed in slide opening downside.

Preferably, the stool is in sliding contact with the safety cabin, and the corners of the stool are provided with rounded corners.

Preferably, the upper surface of the clamping block is obliquely arranged, the lower surface of the wedge block is obliquely arranged, and the clamping block is abutted to the wedge block and is in sliding contact with the wedge block.

Preferably, the safety cabin, the clamping groove and the safety door are all made of medium carbon steel.

The invention has the beneficial effects that:

compared with the prior art, the safety door is quickly and effectively locked through the embedding of the clamping groove and the safety door, and meanwhile, the locking is completed through the clamping block, so that the safety door is prevented from being easily opened by external force, the safety of a user is fully guaranteed, and the user can be ensured to quickly open the safety cabin from the inside as required.
