Description

Lock for hydrant box

A kind of fire hydrant box lock belongs to the fire-fighting equipment special equipment.

At present, domestic widely used fire hydrant box lock, be spring fire hydrant box lock, this lock is because spring is an ankle dew, and Chang Yushui contact in use gets rusty easily, thereby influence the operate as normal of spring, when locking owing to case in addition, spring is a stress always, and the time one is long, the elastic force of spring reduces, operate as normal to lock also has considerable influence, when unpacking, connect switch earlier, treat to unpack again after lock is opened, the time of unpacking, unhappy general unpacking needed for 3 seconds approximately, owing to this lock uses on fire-fighting equipment, usually owing to be in an emergency, needs are very fast and meet the standard of zero tolerance unpacking, because the spring fire hydrant box is latched in above-mentioned shortcoming, use and break down often, brought many troubles to fire-fighting work.

Because the spring fire hydrant box is latched in above-mentioned defective, the purpose of this utility model is to provide a kind of use reliable, opens fire hydrant box lock rapidly.

The utility model is to realize like this.A kind of fire hydrant box lock, it is characterized in that it is by lock cover (1), dead bolt (2), stage clip (3), bayonet lock (4), handle axis (5), handle body (6), handle (7) and outer cover (8) constitute, wherein handle axis (5) two ends are contained on the handle body (6) rotationally, the two ends of handle axis (5) on being contained in handle body (6) rotationally, remainder vertically is embedded in the handle (7), can in handle body (6), rotate around handle axis (5) thereby make (7), as Fig. 1, stage clip (3) one ends are against on the lock cover (1), the other end is against on the interior dead bolt (2) of lock cover (1), bayonet lock (4) is vertically fixed on the dead bolt (2), and the slot (9) that bayonet lock (4) passes on the outer cover (8) is parallel mobile along dead bolt (2) direction front and back in slot (9) length range, as Fig. 2, Fig. 3, Fig. 4, lock cover (1) is fixed on the outer cover (8), as Fig. 2, screw (12) is arranged on the handle body (6), with screw handle body (6) is fixed on the outer cover (8), when stage clip (3) when being in free state, bayonet lock (4) is in an end of slot (9), just in time be against the inner end (10) of handle, as Fig. 3, when human hand direction of arrow in Fig. 4 pulls handle (7), handle (7) rotates along handle axis (5), the inner end (10) of handle shown in arrow among Fig. 1 (7) pushes away bayonet lock (4) to the right along slot (9), dead bolt (2) pressuring spring (3) like this, dead bolt (2) is just all withdrawn and is locked cover, and chamber door has just been opened like this.

The utility model provides a kind of unlatching rapid, service-strong fire hydrant box lock, because lock was also just opened when human pulled handle, the door of unpacking has so just been finished with an action, about 1 second of time kind, in addition, because the stage clip that uses is covered by lock, in use can not come in contact with water, thereby unlikely getting rusty, in addition, when pinning chamber door, stage clip be in loosen, free state, only when opening, be in confined state, because of the spring long service life, durable, safe and reliable.

Below in conjunction with accompanying drawing the utility model is further described:
