Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, and specifically relates to a quick-connect valve for fire hoses. Background Technology

[0002] Current methods for connecting fire hoses and valves have significant technical drawbacks, primarily: traditional snap-fit ​​connections require operators to precisely align the hose and valve fasteners, often resulting in multiple attempts to complete the connection due to inaccurate positioning, severely impacting emergency response speed; existing connection structures rely on rotational fastening, which is not only laborious but also prone to slippage in wet environments. Statistics show that in emergency situations, a reliable connection takes an average of 30-45 seconds, far exceeding ideal operating time. To address these issues, this invention proposes a quick-connect valve for fire hoses, effectively solving the aforementioned technical problems. Utility Model Content

[0007] The clamping assembly includes two connecting plates, a tensile block, and a clamping block. The two connecting plates are symmetrically arc-shaped and symmetrically arranged on the outer periphery of the outer expansion cover.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5As shown, a quick-connect valve for fire hoses includes a connecting assembly 1, a valve body 2, and a hose connecting pipe 3. The connecting assembly 1 is provided with a clamping assembly 4 and a linkage limiting assembly 5 on its outer periphery. The clamping assembly 4 is used to tighten the hose connecting pipe 3 and connect it to the connecting assembly 1. The linkage limiting assembly 5 tightens the hose connecting pipe 3 by flipping it through the clamping assembly 4, and the linkage limiting assembly 5 limits and adjusts the clamping assembly 4 by flipping it.

[0025] The connecting assembly 1 includes a connecting pipe 11, a valve body 2 installed inside a threaded connection cover 12, the threaded connection cover 12 integrally disposed on one side of the connecting pipe 11, a hose connecting pipe 3 disposed on a support 13a, and the hose connecting pipe 3 and the outer expansion cover 13 are correspondingly disposed, the outer expansion cover 13 is integrally disposed on the other side of the connecting pipe 11, and a sealing ring 14 for sealing the hose connecting pipe 3 and the connecting pipe 11 is provided inside the outer expansion cover 13;

[0026] The clamping assembly 4 includes two connecting plates 41, a tensile block 42, and a clamping block 43. The two connecting plates 41 are symmetrically arc-shaped and symmetrically arranged on the outer periphery of the outer expansion cover 13. The connecting plates 41 are made of tough steel and have elastic expansion displacement. The clamping blocks 43 are set in two groups and are both located on the upper side of the support part 13a. Each group of clamping blocks 43 includes two blocks and is clamped to two clamping cones 31. The two clamping cones 31 are fixed on one side of the hose connecting pipe 3. The two groups of clamping blocks 43 are respectively fixed on the opposite sides of the two connecting plates 41. The other side of the outer wall of the hose connecting pipe 3 is provided with a blocking ring 32 for restraining the hose from detaching.

[0027] As an optional implementation, the linkage limiting component 5 includes a flip plate 51, a sliding sleeve 52, a push-pull rod 54, and a smooth linkage plate 55. The flip plate 51 is configured as an open frame and is fitted around the outer periphery of the connecting pipe 11. There are two sliding sleeves 52, which are respectively slidably fitted onto the two side plates of the flip plate 51. There are two smooth linkage plates 55, which are respectively fixed to the sides of the two sliding sleeves 52. The two smooth linkage plates 55 are provided with snap-fit ​​embedded components. A hand grip ring 58 is fixed on the side of the two smooth linkage plates 55 away from the sliding sleeves 52. The two side plates of the flip plate 51 are provided with two sets of central rotating components symmetrically connected to the outer periphery of the connecting pipe 11. This design allows the snap-fit ​​embedded components to achieve flip adjustment by relying on the central rotating components. At the same time, by utilizing the sliding cooperation between the sliding sleeves 52 and the side plates of the flip plate 51, the snap-fit ​​embedded components can achieve embedded blocking after the two connecting plates 41 are translated, thereby maintaining the sealing effect on the hose connecting pipe 3.

[0028] See attached document Figure 2The connecting pipe 11 is symmetrically provided with positioning screws 44 and fixing blocks 17 on its outer periphery. The positioning screws 44 pass through the sliding hole 17a and are threadedly engaged with the bottom surface of the connecting plate 41 away from the clamping block 43. The sliding hole 17a is opened through the fixing block 17. The fixing block 17 is fixed on the outer periphery of the connecting pipe 11 and connected to the side of the outer expansion cover 13. The length of the sliding hole 17a is set to be greater than the displacement when the lower side of the flip plate 51 rotates. In this way, when the connecting plate 41 moves horizontally, it is constrained by the positioning screws 44 and moves horizontally around the outer periphery of the connecting pipe 11, so as to realize the horizontal pulling of the water hose connecting pipe 3 and connect and seal with the outer expansion cover 13.

[0029] See attached document Figure 2 and attached Figure 5 The central rotating assembly includes a flip hole 51a, a first reinforcing block 15, and a central screw 16. The central screw 16 passes through the flip hole 51a and is threadedly connected to the first reinforcing block 15. The first reinforcing block 15 is fixed on the outer periphery of the connecting pipe 11. The flip hole 51a is opened through one of the side plates of the flip plate 51. This allows the flip plate 51 on the linkage limiting assembly 5 to rotate around the central screw 16, thereby realizing the push-pull translation adjustment of the connecting plate 41 and thus coping with the insertion and disconnection operations of the hose connecting pipe 3 and the outer expansion cover 13.

[0030] Furthermore, the push-pull rod 54 is configured as two rods symmetrically distributed on opposite sides of the outer periphery of the outer expansion cover 13. Both sides of the push-pull rod 54 are provided with round holes, and one of the round holes is fitted with a reverse pull screw 53. The reverse pull screw 53 is threadedly engaged with the lower side of one of the side plates of the flip plate 51. Push-pull screws 46 are provided on opposite sides of the two connecting plates 41. The push-pull screw 46 passes through another round hole and is threadedly connected to the second reinforcing block 45. The second reinforcing block 45 is fixed on the outer periphery of the connecting plate 41 on the side opposite to the clamping block 43. This design allows the flip plate 51 to rotate around the center screw 16, which simultaneously drives the push-pull rod 54 to translate and pull the connecting plate 41, thereby driving the clamping block 43 to connect the water hose connecting pipe 3 on the clamping cone 31. This causes the clamping cone 31 at the free end of the water hose connecting pipe 3 to abut against the sealing ring 14, thereby improving the sealing effect between the water hose connecting pipe 3 and the outer expansion cover 13.

[0031] Furthermore, the snap-fit ​​embedded component includes a tensile block 42, an embedded spacer plate 56, and an outer snap ring 57. The tensile block 42 is configured as two pieces and distributed on opposite sides of the outer periphery of the connecting pipe 11. The embedded spacer plate 56 is configured as an open arc shape that snaps into the outer periphery of the connecting pipe 11. After the inner spacer plate 56 is rotated by the flip plate 51 with the central screw 16 as the center, it is embedded between the outer expansion cover 13 and the tensile block 42 on the outer periphery of the connecting pipe 11. The two tensile blocks 42 are respectively set on opposite sides of the two connecting plates 41 and correspond to the first reinforcing block 15. This design allows the outer snap ring 57 to slide synchronously with the sliding sleeve 52, thereby pressing and snapping into the outer periphery of the two connecting plates 41 by sliding along the side plate of the flip plate 51, and achieving a contracted and tightened state on the side of the snap-fit ​​block 43 on the two connecting plates 41, thereby ensuring the snap-fit ​​tensile effect of the snap-fit ​​block 43 on the snap-fit ​​cone 31.

[0032] Furthermore, the outer buckle 57 is designed to be open, and after being flipped and slid down, the clamping block 43 on one side of the two connecting plates 41 is in a retracted state. Both connecting plates 41 are provided with notches to facilitate the insertion of the embedded spacer plate 56 into the connecting tube 11. This design allows the embedded spacer plate 56 to be restricted by the smooth linkage plate 55 and the sliding sleeve 52. When sliding down along the flip plate 51, the embedded spacer plate 56 can be embedded between the two connecting plates 41 and the outer periphery of the connecting tube 11, thereby limiting the position of the translated connecting plate 41 by the thickness of the embedded spacer plate 56.

[0033] Using the above structure, the two locking cones 31 on the hose connection pipe 3 correspond to the locking blocks 43 on the two connecting plates 41. Pressing them together causes the locking cones 31 to embed between the locking blocks 43. The cooperation between the locking blocks 43 and the locking cones 31 creates a linkage effect on the hose connection pipe 3. Then, pulling down the handle ring 58 on the linkage limiting component 5 causes the flip plate 51 to rotate around the center screw 16, simultaneously driving the push-pull rod 54 to pull the connecting plate 41 along the sliding hole 17a. This causes the connecting plate 41 to move the hose connection pipe 3 synchronously and contact the sealing ring 14 inside the outer expansion cover 13. When the hand grips the lever, it drives the smooth linkage plate 55 to rotate to the upper side of the connecting tube 11, so that the inner spacer plate 56 and the outer buckle ring 57 are simultaneously located on the upper side of the connecting tube 11 and the connecting plate 41; then, the smooth linkage plate 55 is pressed down, which drives the sliding sleeve 52 to move down along the side plate of the flip plate 51, so that the inner spacer plate 56 is inserted between the outer expansion cover 13 and the tensile block 42 along the outer periphery of the connecting tube 11, forming an internal support positioning restriction for the connecting plate 41; at the same time, the outer buckle ring 57 moves down and is inserted into the outer periphery of the two connecting plates 41, so that the two connecting plates 41 form a mutually contracting constraint state, improving the connection quality and work efficiency.
