Description

The structure of the pipe clamp

technical field

The utility model relates to two ends of a pipe clamp, in addition to being provided with buckle hook parts which can be fastened together and cannot be disengaged by themselves, the inner tightening surface of the tube when clamping the tube fittings forms an uninterrupted real joint. round face.

Background technique

Generally, after the two pipe fittings are connected with each other, the connecting parts are usually clamped with pipe clamps to prevent the two pipes from detaching. There are many types of pipe clamps. For example, the screw screw is used to make the inner diameter of the pipe clamp gradually shrink, and then tightly bind the pipe fittings; or use a high-tension elastic steel band to roll into a circular pipe clip, and its inner diameter is usually smaller than the outer diameter of the pipe fittings to be tightened, and then use the pipe clip two Apply force at the end to make it stretch out, so that the inner diameter can be expanded to allow the pipe to penetrate, and then release the applied force, and the inner diameter will return to its original shape through the elastic force of the pipe clamp, and then the two pipes will be tightly bound and fixed.

Although each of the above-mentioned pipe clip structures has its own advantages, the one has a relatively large fastening force, but its structure is relatively complicated, the manufacturing cost is relatively troublesome, and the operation is relatively troublesome; the other is simple in structure, low in cost, and relatively easy to operate. , but the fastening force of its shackles is not enough.

Therefore, there is the pipe clamp of the elastic ring buckle shown in Figure 1 and Figure 2, one of its two ends is open and extends the overlapping elastic ring body 1, and forms a tightening surface 10 on the inner side of the ring body, and one end is bent to set a The hook part 11, the other end is provided with a hooked part 13 that can be hooked by the hook part 11, and the end of the hooked part 13 is extended with a superimposed edge 19, a convex guide part 15 and a guide end 14, And between the hooked part 13 and the superimposed edge 19, there is provided a sliding guide part 16 that can guide the hook part 11 to slide over, and at the same time, a protruding guide part is provided on the inner side of the ring body on the side of the hook part 11. 15 and the guiding end 14 slide into the guide groove 12, so when the pipe is inserted into the pipe clamp, force is applied to make the hook part 11 hook on the hooked part 13, so that the inner diameter of the ring body 1 is reduced and the tightening surface 10 The pipe fittings are tightly bound, so the fastening force after buckling is not only strong, but also difficult to loosen, and can be reused.

However, although the above-mentioned pipe clamp provides better tightening effect and simple operation, when the pipe is clamped on the pipe fitting, the tightening surface 10 cannot be a true circle, resulting in the inability to completely connect with the pipe fitting. Contact, leaving a large gap S, resulting in a reduction in the contact area between the pipe clamp and the pipe fittings, which relatively reduces the friction between the two, and at the same time, the gap S is also bound by the contact constraint of the non-tightening surface 10 and Compression will cause the liquid under pressure in the pipe to leak out from there, that is, the larger the gap, the higher the possibility of leakage.

Utility model content

In order to further improve the tightening ability of the pipe clamp, the purpose of the utility model is to provide a structure of the pipe clamp.

In order to achieve the above-mentioned purpose, the technical approach implemented in the structure of the pipe clamp of the utility model is to make the predetermined positions of the open ends of the two ends of the ring body of a pipe clamp be provided with a hook part and a hook part that can be fastened with each other. , and let the end of the hooked part continue to extend with a superimposed edge and a narrower leading end, and the side of the hook part is provided with a submerged part that can be slightly enlarged for the superimposed side to close, and for The guide groove where the leading end is submerged makes the inner tightening surface of the ring body and the inner tightening surface of the superimposed edge form a continuous and uninterrupted true round surface after the buckling hook part and the hook receiving part are fastened together.

The beneficial effect of the utility model is that when the pipe clip of the utility model is penetrated by the pipe fitting and the buckle hook part and the hook receiving part are fastened together, the superimposed edge of the end of the hook receiving part does not fit in the submerged part, and the leading end does not fit at the end of the guide groove, so that the tightening surface of the ring body and the superimposed edge and the inner tightening surface of the leading end are staggered, so that the entire inner surface can be completely tightly connected with the pipe fitting. Fit together without interruption, so that there will be no gap between the pipe clamp and the pipe to be bundled, so that the tightening force of the pipe clamp can fully act on the pipe, not only improving the effect of tightening, but also preventing Leakage of liquid inside a fitting.
