Description

The utility model relates to a pipe clip.

At present, it is widely used to fasten the pipe clamp at the joint of the delivery pipe. The structure of one of the commonly used pipe clamps is shown in Figure 1 and Figure 2. Both sides of the metal sheet forming the pressing head (20) are respectively provided with protruding Wing (201), after the metal sheet is bent and formed to tighten the head (20), the wing (201) and the flat end of a bundle (21) are pressed together first, and then the two are welded by spot welding Form a fixed structure, but because the materials of the tightening head (20) and the belt (21) cannot be guaranteed to be the same, the degree of welding tightness between the two is relatively poor, and it is impossible to make the pipe clamps have a strong front and rear, left and right sides. combination. The pipe clamp of this structure is only suitable for low-pressure pipelines. If it is used for high-pressure pipelines, it is easy to open and weld, causing cracks. The second structure of the commonly used pipe clamp is shown in Figure 3 and Figure 4. The two ends of the wing (301) of the tightening head (30) are made into protruding insertion parts (302), and are matched with them. An insertion hole (310) is provided at the flat end of the belt (31), and the insertion part (302) on the wing (301) is inserted into the insertion hole (310) on the belt (31) Form a consolidated structure, because the combination is staggered and interspersed, so it is necessary to complete the reverse insertion between the insertion part (302) and the insertion hole (310) by manual combination, and when the tightening head (30) and the bundle After the bands (31) are combined, they must be pressed and fixed to make the two consolidated, which makes the manufacturing process complicated, labor-intensive and time-consuming. Since the joint area between the inserting part (302) and the inserting hole (310) is not large, it is very easy to cause the tightening head (30) and the drawstring (31) to fall off and separate during tightening.

The purpose of the utility model is to avoid the disadvantages of the above-mentioned prior art and provide a pipe clip with simple manufacturing process, low cost, high bonding strength, easy assembly and use.

The technical solution of the utility model is: the pipe clamp is composed of a tightening head, a tightening bolt and a belt with oblique holes; wherein, two wings of different sizes are formed at the lower end of the tightening head, and the large wing is in the shape of Bending shape, and the end forms a depressed joint surface, the front end of the joint surface is extended with a clamping part, the small wing part is superimposed on the joint surface of the large wing part, and it is flat after joining, with a flat Welding plane; one end of the belt is provided with a clamping hole, the size of the clamping hole is equivalent to the size of the joint surface, and it passes through the clamping part and is clamped against the joint surface.

The utility model improves the joint structure of the lower wing of the clamping head and the joint structure of the clamping head and the belt, so that the pipe clamp has a simple manufacturing process and strong binding force in the front, rear, left and right directions, making it suitable for clamping During the process, there is no phenomenon of cracking or structural detachment. Moreover, the parts and components of the pipe clamp are simple in structure and can be produced independently without consuming too much manpower and equipment costs. It has the characteristics of high bonding strength, easy assembly and easy use, and is suitable for wide use in various high and low pressure pipelines.

The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments: Referring to Fig. 5, Fig. 6, and Fig. 9, a pipe clamp is composed of a tightening head (5), a tightening bolt (50) and a The hole (60) is an integrated structure composed of the belt (6), wherein the tightening head (5) is a metal sheet bent into an arch shape, and a tightening bolt (50) is arranged inside it, and the two ends of the metal sheet form a large , the two small wings (51), (52), the large wings (51) are bent, and the ends are properly formed with a sunken joint surface (510), as shown in Figure 8, the front end of the joint surface (510) The protrusion is provided with a clamping part (511), and its small wing part (52) is superimposed on the joint surface (510) through bending, and the outer end surface is flat after joint, so that the two can have a joint when welding. The best combination plane, because the large and small wings (51) and (52) at the lower end of the tight head (5) are made of the same material, so after superimposed welding, there is a good degree of closeness, so that the The left and right directions are combined very firmly to form a strong binding force. Referring to Fig. 5 and Fig. 7, the strap (6) is a metal strip with an appropriate length, one end of which is punched with an oblique hole (60), and the other end is provided with a card hole (61). The size of the hole (61) is equivalent to the size of the joint surface (510) of the large wing (51), so that after the clamping hole (61) passes through the clamping part (511), it can be further clamped against the joint surface ( 510), so that the front and rear directions also have a strong binding force. Therefore, the utility model also has strong binding forces in the four directions of front, rear, left and right, so that it can be used in low-pressure pipelines or The high-pressure pipeline can make the conveying pipe and the joint present the best tight and locked state, and there is no excessive force at the junction of the compression head (5) and the belt (6) due to improper force application The situation of cracking.

When in use, as shown in Figure 10, a belt (6) of appropriate length can be taken, and the clamping hole (61) on the belt (6) is sleeved on the clamping part at the front end of the large wing (51) (511), wrap the movable end of the belt (6) on the delivery pipe and the joint, and make the end pass through the tightening head (5), and engage the bundle by the rotation of the tightening bolt (50) The oblique hole (60) on the belt (6) tightens the junction of the delivery pipe and the joint, and achieves the best tightening effect.
