Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings,
As shown in Figs. 1-2, a kind of clamp type fire extinguishing water hose water-stop connection structure, including water-stop 1, the valve body of water-stop 1
On be connected with fire fighting fastener 2, fire fighting fastener 2 includes the outer buckle ring 21 being connected with valve body, and outer buckle ring 21 is internally provided with internal buckle
Ring 22, the surface of internal buckle ring 22 is equipped with several annular through groove 221, the wedge-shaped catch 3 of activity is equipped in annular through groove 221, described
Spring 4 is equipped between the outer wall of wedge-shaped catch 3 and outer buckle ring 21；Pipe fitting 5 is further included, the end of pipe fitting 5 has a /V
Step 51, and pipe fitting 5 is arranged in the valve body of the water-stop 1, and the wedge-shaped catch 3 has under the action of spring 4
The trend compressed to pipe fitting 5, and the limited step 51 of the pipe fitting 5 is blocked, fire hose is connected on pipe fitting 5
, when pipe fitting 5 is connected on water-stop 1, pipe fitting 5 is had into one end of limited step 51 along clearance portion 8
Position is inserted into, and limited step 51 will lift wedge-shaped catch 3, since wedge-shaped catch 3 is under the action of spring 4, is just compressed
On annular through groove 221, so it is with corresponding displacement space, therefore during pipe fitting 5 stretches into, wedge-shaped catch
3 can continuous raised positions, until when wedge-shaped catch 3 is not contacted with two upper and lower surfaces of pipe fitting 5, pipe fitting 5 completely into
It being connected with valve body, wedge-shaped catch 3 is pressed on annular through groove 221 under the action of spring 4 again, and forms /V to pipe fitting 5,
Prevent its extraction.
As shown in Fig. 2, in above-mentioned clamp type fire extinguishing water hose water-stop connection structure, the bottom of the water-stop 1 is equipped with
Supporting rack 6.Water-stop 1 is under normal circumstances to be revocable, then when water-stop to be closed, lacks supporting point, valve below
The rotation of handle can seem that comparison is painstaking, therefore increase supporting rack 6 in the bottom of water-stop 1, on the one hand play the role of support,
Still further aspect supporting rack 6 can be also fixed on the boss of part, provide stress supporting point, rotate valve handle more convenient.
As shown in Figure 3-4, in above-mentioned clamp type fire extinguishing water hose water-stop connection structure, 5 external connection of pipe fitting
There is the solution division ring 7 of activity, have one between the outer wall of the pipe fitting 5 and the outer wall of internal buckle ring 22 for solving between division ring 7 stretches into
Gap portion 8.When pipe fitting 5 is disassembled from water-stop 1, solution division ring 7 is pushed into clearance portion 8, wedge shape can just be kept off
Block 3 is promoted, and at this time extracts pipe fitting 5, since the height of 7 end of solution division ring is slightly above 5 limited step of pipe fitting
51 height, when extracted, wedge-shaped catch 3 abutted before this with solving the surface of division ring 7, then were abutted with the surface of limited step 51,
Pipe fitting 5 would not be stopped by wedge-shaped catch 3, can smoothly be taken apart.
As shown in Figure 3-4, in above-mentioned clamp type fire extinguishing water hose water-stop connection structure, the outer end of the solution division ring 7 is also
Equipped with a pushing board 71, the operation of solution division ring 7 is convenient in the setting of pushing board 71.
As shown in figure 5, in above-mentioned clamp type fire extinguishing water hose water-stop connection structure, the wedge-shaped catch 3 connects close to pipe
First 5 one end includes inclined riser portions 31, when the effects of riser portions 31 has wedge-shaped catch 3 to abut against with other planes,
Tool is there are one the process risen, comparatively steadily and flat stop for distal ends 32, when stop for distal ends and other planes abut against
When.The variation that wedge-shaped catch 3 is no longer subjected to displacement.
In above-mentioned clamp type fire extinguishing water hose water-stop connection structure, the solution division ring 7 is close to one end of wedge-shaped catch 3
End forms fillet, and the process that the presence of fillet makes solution division ring 7 be abutted against with wedge-shaped catch 3 is more smooth.
As shown in figure 5, in above-mentioned clamp type fire extinguishing water hose water-stop connection structure, the transverse direction of the wedge-shaped catch 3 is long
Degree is greater than the length of annular through groove 221, and the both ends of wedge-shaped catch 3 have inclined limiting section 33, this at two design it is equal
It is to avoid wedge-shaped catch 3 offside, causes disabler.
As shown in Figure 3-4, in above-mentioned clamp type fire extinguishing water hose water-stop connection structure, the end of the valve body also has
One annular groove 9, annular groove 9 is interior to be equipped with seal washer 10,51 shape of limited step of seal washer 10 and annular groove 9 and pipe fitting 5
Into the first sealing area.The seal washer 10 has a deformations, since the deformations 11 are in barb-like, in the annular groove 9
During interior water-filling, hydraulic pressure can force the deformations 11 of seal washer 10 to compress the position of pipe fitting 5 and valve body contact, make sealing effect
More.
In above-mentioned clamp type fire extinguishing water hose water-stop connection structure, the outer buckle ring 21 is threaded on valve body, outside
The outer end of retaining ring 21 has the first stopper 211, and the outer end of the internal buckle ring 22 has the second stopper 222, and internal buckle ring 22
The upper end of second stopper 222 is against on the inner wall of outer buckle ring 21, outer end and 21 first stopper 211 of outer buckle ring of the second stopper 222
Inner end mutually abut.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
