Description

Pressing collar of fire water supply pipe and its combined structure

This creation is about an urgent bundling, especially an improved tightening of the girth and its combined construction applied to the fire water supply pipe.

When today's fire trucks take water, they use a water supply pipe to connect to the fire hydrant to take water. In order to connect the water supply pipe to the fire hydrant quickly, a quick-connect joint is usually implemented at the end of the water supply pipe. a connecting pipe, inserting a pagoda-shaped connecting pipe into a hose (water supply pipe), and then tightening a bundle of rings around the outer periphery of the hose, so that the front end of the quick-connecting joint can be connected to the fire faucet to take water, and The bundle ring period makes the inner wall of the hose and the connecting pipe of the quick-change joint close to prevent the quick-connect joint and the hose from loosening due to the internal high pressure when the water is taken, and prevents the water from leaking out from the socket portion.

However, the conventional bundle ring structure is composed of two semicircular ring pieces, and the ring piece is clamped on the outer periphery of the hose (water supply pipe), and then the two ring pieces are clamped by the fixing member (water supply pipe). Due to the structure of the two semi-circular ring pieces, it is not easy to form the roundness, so when clamping the outer periphery of the hose, the problem of uneven distribution of the clamping force often occurs, for example, the clamping force is concentrated in the two side regions. Other areas do not have the same urgency, so high-pressure water flows easily from less dense parts. To this end, how to improve the shortcomings of the conventional bundle ring is the subject that the creative office must actively overcome.

The purpose of the present invention is to provide a compression collar of a fire water supply pipe and a combined structure thereof, which is improved by a tight bundle ring structure composed of three clamping units and three bolts, thereby preventing the water supply pipe from being loosened and preventing water leakage. It is easy to adjust the axial position of the tight collar.

In order to achieve the above object, the pressing collar of the fire water supply pipe can be restrained on the periphery of a spiral hose, and the spiral hose is tightly sleeved on a quick-change joint. The preferred technical solution includes: three clamping The unit, the three clamping units can be combined into a ring body, wherein each of the clamping units has a circular arc clip, respectively protruding from a first locking block on the outer side of the two ends of the circular clip a second locking block, and a groove formed on an inner side surface of each of the arc clips; and three bolts, each of the bolts passing through the first locking block of each of the arc clips, and being locked and another one The second locking block of the circular clip enables the groove on the inner side of the circular clip to be clamped outside the spiral hose and tightly binds the spiral hose.

In the pressing collar of the fire water supply pipe, the groove on the inner side of the arc clip is a spiral groove, and the outer periphery of the spiral hose has a spiral ridge.

In the above-mentioned pressing bundle of the fire water supply pipe, the first locking block is provided with a through hole, and the second locking block is provided with a screw hole, and the bolt is locked to the screw hole after passing through the through hole.

In the above-mentioned tight tightening ring of the fire water supply pipe, the bolt is a socket bolt.

The present invention also provides a combination structure of a fire hose, which comprises: a connecting pipe at one end of the quick-connecting joint, and a connecting pipe of one end of the spiral hose in the quick-connecting joint, the three A circular clip of the clamping unit surrounds the periphery of the spiral hose, and the bolt passes through the first locking block of each of the circular clips, and the second lock of the other circular clip is locked The block, the groove on the inner side of the circular clip is clamped outside the spiral hose, and the spiral hose is tightly restrained.

The pressing bundle ring of the fire water supply pipe and the combined structure thereof make the arc clips of the three clamping units surround the spiral hose and merge into a ring body, so that the groove on the inner side of the arc clip is clamped at Outside the spiral hose, by tightening the bolts, the arc clips tightly bind the spiral hose, and the spiral hose is tightly sleeved in the connecting pipe of the quick-change joint, so that it can prevent loosening and prevent water leakage. And other effects. In addition, the effect of easily adjusting the axial position of the tight bundle ring can be achieved.

The structural features of the present creation and other functions and purposes are described in detail in the following embodiments:

Referring to FIG. 1 , FIG. 2 and FIG. 3 , the pressing collar of the fire water supply pipe and the combined structure thereof are used for binding the outer periphery of a spiral hose 20 so that the spiral hose 20 is tight. The sleeve is connected to a quick-change joint 30, and the quick-connect joint 30 is used to lock the water faucet and the like to take water. The preferred embodiment of the compression collar 10 includes three clamping units 1 that can be combined into a circular body, wherein each clamping unit 1 has an aluminum alloy circle. The arc clips 11 are respectively integrally formed on a first locking block 12 and a second locking block 13 which are respectively disposed on the outer side surfaces of the two ends of the arc clip 11 and are integrally formed on each of the arcs. a groove 14 on the inner side of the clip 11; and three bolts 2, each of the bolts 2 passing through the first locking block 12 of each of the arc clips 11 and being locked to the other of the arc clips 11 The second locking block 13 is configured to fit the three circular clips 11 on the periphery of the spiral hose 20 to form a circular body. When the bolts 2 are screwed, the inner side of the circular clip 11 is made The groove 14 is clamped outside the spiral hose 20 and tightly binds the spiral hose 20 so that the spiral hose 20 is tightly coupled with a pagoda-type connecting pipe 301 of the quick-change joint 30 ( As shown in Figure 4, the function of preventing looseness or water leakage is achieved.

Referring to FIG. 3 again, the groove 14 on the inner side of the arc clip 11 of the clamping unit 1 is preferably embodied as a spiral groove, and the spiral hose 20 has a spiral ridge 201 on the periphery thereof. Thereby, the spiral groove of the circular clip 11 is clamped on the spiral ridge 201 of the spiral hose 20. When the axial position of the tight collar 10 needs to be adjusted, the bolt 2 can be rotated as long as the bolt 2 is loosened. The pressing collar 10 makes it easier to adjust the position of its tight restraint. Moreover, the preferred embodiment of the first locking block 12 is provided with a circular tangential direction through hole 121, and the second locking block 13 is provided with a screw tangential hole 131 in the tangential direction, thereby passing the bolt 2 through. The through hole 121 is then locked to the screw hole 131 to achieve a tight binding function. Furthermore, the bolt 2 described above is preferably embodied as a socket bolt.

Through the improvement of the pressing collar 10 described above, the pressing collar 10 is assembled to the spiral hose 20, and the combination and structure of the spiral hose 20 and the quick-change joint 30 are tightly coupled, so that the spiral is soft. One end of the tube 20 is sleeved on the connecting tube 301 of the quick-change joint 30, and the circular clips 11 of the three clamping units 1 are surrounded by the outer periphery of the spiral hose 20, and then the bolts 2 are passed through. The first locking block 12 of each of the circular clips 11 and the second locking block 13 of the other circular clip 11 are locked by the three clamping units 1 It is more effective in preventing loosening or preventing water leakage.

In summary, the tight-fitting ring of the fire-fighting water supply pipe and its combined structure have been practical and creative, and the application of its technical means is also novel and undoubted, and the effect and design purpose are in line with it. Progress is clear. To this end, a new type of patent application is filed in accordance with the law, but the bureau is requested to give a detailed examination and grant the patent as a prayer.
