Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to a fire-fighting interface with a water-stopping mechanism. Background Art

[0002] Firefighting is a general term for solving or preventing man-made, natural and accidental disasters that people encounter in the process of life, work and study. In firefighting work, the firefighting interface is an important component connected to the fire hose;

[0003] Chinese patent authorization application number: CN201822200152.2 provides a fire interface that is easy to connect. The solution is to set a mother card block on the fire belt, set a ring on the fire belt, insert the fire belt into the connection groove formed by the right side of the fire interface body and the outer ring, so that the ring contacts the card rod, compresses the card rod to pull the spring, and moves the ring to the left side of the card rod, and pushes the card rod to clamp the ring by pulling the spring to restore the elastic deformation of the thrust, and fix the fire belt on the fire interface body. By setting the mother card block and the child card block as an inclined surface, the mother card block and the child card block are in contact, so that the thrust of the push spring to restore the elastic deformation pushes the child card block to press the fire belt through the mother card block, and a quick connection is achieved. The fire belt can be removed from the fire interface body by pulling the handle to separate the card rod from the ring, which solves the problem that the fire interface is very inconvenient to connect with the fire belt and cannot be quickly connected. The most important point of fire protection is time. If the fire belt cannot be connected to the fire interface in time, the fire risk will be increased and the efficiency of fire extinguishing will be affected.

[0004] The existing fire-fighting interfaces have certain drawbacks when in use. First, the structure of the fire-fighting interfaces is relatively simple, which makes them inconvenient to use. In addition, when the water source needs to be blocked, the operation is inconvenient, which affects the use effect of the fire-fighting interfaces. For this reason, we propose a fire-fighting interface with a water-stop mechanism. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a fire interface with a water-stop mechanism. By setting an elastic ball and a closed edge, the movable ball moves to drive the elastic ball to adjust its position, so that the movable part is connected to the inside of the main body mechanism, so that the fire interface can perform water-stopping work more thoroughly to avoid leakage, and the operation is convenient, which is used to solve the problem of inconvenient water stopping of the fire interface; by setting a clamping block, the circular clamping block cooperates with the external arc groove, which not only allows the clamping block to be stably connected with the main body mechanism to prevent water leakage, but also when the water source is needed, the clamping block is separated from the connecting mechanism more conveniently, thereby improving the use effect of the water-stop structure; by setting an arc block, it can be easily separated when the main body mechanism is connected to the water source, so that the device can be easily switched between the water outlet and water-stopping states, thereby improving the use effect of the fire interface.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A firefighting interface with a water stop mechanism comprises a main body mechanism, the inner end of the main body mechanism is slidably connected to an adjusting mechanism, and the outer end of the adjusting mechanism is movably connected to a connecting mechanism;

[0010] Furthermore, a movable piece is sleeved on the outer end of the movable rod, and a limiting groove is formed on the outer end of the movable piece.

[0014] Furthermore, a clamping block is installed at the bottom end of the pair of movable rods, the clamping block is a circular structure, and the outer end of the clamping block is provided with symmetrically distributed arc grooves.

[0015] By installing the clamping block, the use effect of the water-stopping structure can be improved.

[0016] Furthermore, the main body mechanism includes a connecting tube 1, the front end of which is installed with an interface body, the rear end of which is threadedly connected with an adjusting tube, and the rear of which is movably connected with a connecting tube 2.

[0017] By installing the adjusting tube, the adjusting tube is connected by a connecting tube-thread connection, so that the connection and installation between the device structures are more convenient and the practicality is improved.

[0018] Furthermore, an outer end of the second connecting pipe is provided with an external adjustment sleeve, and an inner end of the second connecting pipe is provided with an adjustment chamber.

[0019] By installing the external adjustment sleeve, the stability of the connection between the device structures can be increased.

[0020] Furthermore, the inner end of the main body mechanism is slidably connected with a connecting piece, the connecting pieces are symmetrically distributed, and the outer ends of the connecting pieces are all installed with arc blocks.

[0022] Furthermore, the arc block is movably connected to the outside with a reset ring, and the reset ring is located at the bottom end of the elastic ball.

[0023] By installing the reset ring, the reset ring loses its restriction and can drive the elastic ball to reset, making the adjustment of the elastic ball more convenient.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. By setting the elastic ball and the closed edge, when the device needs to be closed for water stop, the rotating main body mechanism is adjusted to make the movable ball move to drive the elastic ball to adjust its position, which drives the closed edge to move, and makes the movable part clamped inside the main body mechanism, so that the fire interface can stop water more thoroughly to avoid leakage, and the operation is convenient, which improves the use effect of the fire interface;

[0026] 2. By setting the card block, the circular card block cooperates with the external arc groove, which not only can stably connect the card block with the main body to prevent water leakage, but also it is convenient to separate the card block from the connecting mechanism when the water source is needed, thereby improving the use effect of the water-stopping structure;

In addition, the special structure of the arc block can be easily separated when the main body mechanism is connected to the water source, so that the device can be easily switched between the water outlet and water-stopping states, thereby improving the use effect of the fire protection interface.

[0036] Reference Figure 1-5 As shown, a fire-fighting interface with a water-stop mechanism in a preferred embodiment of the utility model comprises a main body mechanism 1, an adjusting mechanism 2 is slidably connected to the inner end of the main body mechanism 1, and a connecting mechanism 3 is movably connected to the outer end of the adjusting mechanism 2;

[0037] The adjustment mechanism 2 includes a reset member 201, an outer end of which is equipped with a movable ball 202, the outer end of which is movably connected to a connecting tube 203, the lower end of which is movably connected to an elastic ball 204, the outer end of the elastic ball 204 is fixedly connected to a symmetrically distributed closed edge 205, the closed edge 205 is a trapezoidal structure, and the inner end of the closed edge 205 is slidably connected to a movable rod 206.

[0038] Reference Figure 2-3 As shown, further, a movable member 207 is sleeved on the outer end of the movable rod 206 , and a limiting groove 208 is opened on the outer end of the movable member 207 .

[0039] Reference Figure 3 As shown, further, the limiting groove 208 is located at the inner end of the closed edge 205 , and the front side of the movable member 207 is slidably connected with a guide block 209 , and the guide block 209 is located at the outer end of the movable rod 206 .

[0040] Reference Figure 3As shown, further, a clamping block 210 is installed at the bottom end of the pair of movable rods 206. The clamping block 210 is a circular structure, and the outer end of the clamping block 210 is provided with symmetrically distributed arc grooves 211.

[0041] By installing the elastic ball 204 to adjust the position, the elastic ball 204 drives the external closed edge 205 to adjust the position. After the closed edge 205 moves to a certain position, the movable rod 206 sliding inside the closed edge 205 drives the movable part 207 to be connected to the inside of the main body mechanism 1. The guide block 209 cooperates with the limiting guide of the limiting groove 208, so that the movable rod 206 can drive the block 210 to make small position adjustments more stable. The circular block 210 cooperates with the external arc groove 211, which not only allows the block 210 to be stably connected with the main body mechanism 1 to prevent water leakage, but also when the water source is needed, it is more convenient to separate the block 210 from the connecting mechanism 3, so that the fire interface can perform water stopping work more thoroughly to avoid leakage.

[0042] Reference Figure 1 As shown, further, the main body mechanism 1 includes a connecting tube 101, the front end of which is installed with an interface body 102, the rear end of which is threadedly connected with an adjusting tube 103, and the rear of the adjusting tube 103 is movably connected with a connecting tube 2 104.

[0043] Reference Figure 1-2 As shown, further, an outer end of the second connecting pipe 104 is sleeved with an external adjustment sleeve 105 , and an inner end of the second connecting pipe 104 is opened with an adjustment chamber 106 .

[0044] By installing the external adjustment sleeve 105, the connection between the second connecting pipe 104 and the adjustment pipe 103 can be more stable, thereby increasing the stability of the connection between the device structures.

[0045] Reference Figure 2 and Figure 4 As shown, further, the inner end of the main body mechanism 1 is slidably connected with a connecting piece 301 , the connecting pieces 301 are symmetrically distributed, and the outer ends of the connecting pieces 301 are all installed with arc blocks 302 .

[0046] Reference Figure 2 As shown, further, the outer part of the arc block 302 is movably connected with a reset ring 303 , and the reset ring 303 is located at the bottom end of the elastic ball 204 .

[0047] By installing the arc block 302 and snapping it into the arc groove 211, the water-stopping work of the adjustment mechanism 2 can be made more sealed, and the special structure of the arc block 302 can also be easily separated when the main body mechanism 1 is connected to a water source, so that the device can be easily switched between the water outlet and water-stopping states.

[0048] Specific implementation process: connect the connecting pipe 2 104 to the external water source. When water stopping is required, adjust the external adjustment sleeve 105. At this time, adjust the rotating main body mechanism 1 to allow the movable ball 202 to move and drive the elastic ball 204 to adjust its position. The elastic ball 204 drives the external closed edge 205 to adjust its position. After the closed edge 205 moves to a certain position, the movable rod 206 sliding inside the closed edge 205 drives the movable part 207 to be clamped in the inside of the main body mechanism 1. The movable rod 206 cooperates with the movable part 207 sleeved on the outside to drive the clamping block 210 to make a small position adjustment as the external force acts, so that the clamping block 210 can be connected with the connecting mechanism 3 more conveniently as the main body mechanism 1 is adjusted. The circular clamping block 210 cooperates with the external arc groove 211, which can not only make the clamping block 210 and the main body mechanism 1 stably clamped to prevent water leakage, but also when the water source is needed, the clamping block 210 is separated from the connecting mechanism 3 more conveniently, and water stopping work can be performed at this time.

[0049] The arc block 302 is snap-fitted with the arc groove 211, which allows the adjustment mechanism 2 to perform water-stopping work more tightly. In addition, the special structure of the arc block 302 allows for easy separation when the main body mechanism 1 is connected to a water source, allowing the device to be easily switched between water outlet and water-stopping states, thereby improving the use effect of the fire protection interface.
