Description

Integrated high-pressure fire hose quick connector

Technical Field

The utility model relates to a fire-fighting equipment technical field specifically relates to an integrated form high pressure fire hose quick connector.

Background

Forest fires are natural disasters which have the greatest influence and harm on forestry forests, and economic, social and environmental benefits are greatly lost due to forest fires every year. China has low forest coverage per se, and has a large gap with developed countries although the investment on forestry construction is increased in recent years. At present, most forest zones in China have the phenomena of scattered distribution, unreasonable layout and the like of forest zone management stations, so that forest zone management personnel, fire prevention and fire fighting personnel are not concentrated and can not usually fight the fire in the first time of fire, and the difficulty of forest fire prevention is increased due to the factors of less forest zone management personnel, poor professional skills and the like.

In forest fires, the distance between a fire scene and a water source is also far away, and the traditional fire-fighting water separator is provided with a plurality of joints, can put through a plurality of fire-fighting water hoses simultaneously, but because a plurality of fire-fighting water hoses share one water separator to supply fire-fighting water, the purpose of remotely conveying the water source and cooperatively fighting by a plurality of people can not be well played when fires such as forests and the like, and the fire-fighting effect is not good.

Through prior art search discovery, chinese utility model patent publication is CN109595362A, and it discloses a water knockout drum for fire control relates to water knockout drum technical field, and its technical scheme main points are: the water diversion connector comprises a main connector and a water diversion connector in threaded connection with the main connector, wherein a main runner is arranged inside the main connector, a branch runner is arranged inside the water diversion connector, a control valve used for controlling the opening and closing of the branch runner is arranged on the water diversion connector, and a first sealing ring is sealed between the main connector and the water diversion connector. The fire-fighting water separator is divided into the main joint and the water dividing joint, so that the main joint and the water dividing joint can be processed respectively. Because the volume of the main joint is smaller, the main joint can be conveniently turned over when a main runner inside the main joint is machined, and the machining of the main joint is more convenient and quicker. Because the sprue length is shorter, so the user can comparatively conveniently process out the inside sprue of owner joint, reduced the processing degree of difficulty of this water knockout drum for fire control to a certain extent, reduced the time that this water knockout drum for fire control required cost of production. The utility model discloses a just there is the unable remote transport scheduling problem of above-mentioned.

the side of the lock column 62 connected to the second base 12 can be welded, preferably screwed, so as to facilitate disassembly, and the length of the lock column 62 connected to the side of the second base 12 is matched with the width of the hook groove 611, preferably, the diameter of the end of the lock column 62 located outside the second base 12 is greater than the diameter of the cylinder thereof, so as to prevent the hook handle 610 from moving outwards and deviating when rotating.

The lock cylinder 62 is sleeved with a sliding sleeve 7. The sliding sleeve 7 is arranged on the lock column 62, the sliding sleeve 7 slides along the lock column 62 in the radial direction, when the hook groove 611 is connected with the lock column 62 in a sliding mode, the sliding sleeve 7 serves as a rotating body to be in contact with the hook groove 611, so that in the process that the lock column 62 reaches the bottom along the port of the hook groove 611, sliding friction between the hook groove 611 and the lock column 62 is changed into rolling friction due to sliding of the sliding sleeve 7, friction resistance is reduced, and the engaging speed of the first base 11 and the second base 12 is improved.

The inner groove surface of the hook groove 611 is a frosted surface or a groove surface with a grain. The groove surface of the arc-shaped sliding groove, i.e. the inner groove surface of the hook groove 611, is set to be a frosted surface or a groove surface with a grain, so that the friction force between the groove surface and the sliding sleeve 7 can be increased, and when the lock cylinder 62 reaches the bottom end of the hook groove 611, the self-locking effect can be improved by increasing the friction force between the hook groove 611 and the sliding sleeve 7.

The locking device comprises 2 groups of locking devices 6, 2 groups of locking devices 6 are symmetrically arranged, and the end parts of the hook handles 610 deviating from the hook groove 611 are fixedly connected through a push rod 10. 2 sets of symmetrical locking devices 6 are arranged on two sides of the first base 11 and the second base 12, the top ends of the hook handles 610 are connected together through the push rod 10, namely, the first base 11 and the second base 12 can be quickly switched between a locking state and an unlocking state by pushing or pulling the push rod 10, and the efficiency is improved.

Still include stopper 8, stopper 8 is equipped with flexible post 81, stopper 8 through connection in on the

hook handle

610, 11 sides of first base are equipped with spacing hole 9, the tip of flexible post 81 can stretch into in the spacing hole 9 or withdraw from in the spacing hole 9. The limiting block 8 is connected to the hook handle 610 and rotates along with the rotation of the hook handle 610, when the lock column 62 reaches the bottom end from the port of the hook groove 611 by rotating the hook handle 610, namely, when the first base 11 and the second base 12 reach a fastened state, the telescopic column 81 passes through a spring in the limiting block 8 or a direct external force action, so that the end of the telescopic column 81 extends into the limiting hole 9, the purpose of fixing and locking is achieved, double safety is formed by self-locking of the hook groove 611 and the lock column 62, namely, a redundant effect of locking is achieved, when unlocking is needed, the limiting block 8 can be shifted outwards by external force, so that the telescopic column 81 is withdrawn from the limiting hole 9, and then is unlocked by push-pull force.

Preferably, a group of the male and female quick connectors 2 in the base 1 is different from the rest in nominal diameter, shape or color. Set up multiunit public female mouthful quick-operation joint 2 on base 1, preferably 10 groups, wherein 1 group is as the fire hose of the water of supply different pressure, the operating pressure of infiltration pipe in the high-pressure fire hose of integrated form is less, can not let in the fire water of the same high pressure, for this reason, through setting up 1 public female mouthful quick-operation joint 2 of group nominal diameter, the shape structure size difference can prevent to miss to insert the problem that leads to the infiltration pipe to burst, also can distinguish through the colour simultaneously, if brush different colours in order to reach the purpose of effective difference.

The foregoing description of the specific embodiments of the invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
