The pipe fastener is formed with that the front, the back, the left, and the right parts of the pipe fastener have the strong combining force, and the best fastening effect can be presented. The utility model has the characteristics of high combining strength, convenient assembly and use, etc. The utility model is widely suitable for the various high pressure and the low pressure pipelines.

Description

Pipe fastener

The utility model relates to a kind of pipe clamp.

At present, be widely used in the pipe clamp of fastening delivery pipe joint, one of its pipe clamp commonly used structure such as Fig. 1, shown in Figure 2, the tinsel both sides that form clamping head (20) respectively are provided with the alar part (201) that protrudes out shape, this tinsel is behind brake forming clamping head (20), with the pressing of going ahead of the rest of the smooth end of its alar part (201) and a band (21), through the spot welding mode both are welded again and form fixing structure, but because of clamping head (20) can't be guaranteed necessarily identical with both materials of band (21), so both welding closed intensities are relatively poor, can't make pipe clamp form front and back, about all have strong combination force.The pipe clamp of this structure is only applicable on the low pressure line, if be used for pressure duct, easily snaps, and causes to split.Two structures such as Fig. 3 of its pipe clamp commonly used, shown in Figure 4, the embedded part (302) of convex shape is made at alar part (301) two ends of this clamping head (30) in addition, and establish one at the smooth end place of its band that matches (31) and insert embedding hole (310), embedded part (302) on this alar part (301) is inserted and is formed a consolidation structure in the slotting embedding hole (310) that is embedded on the band (31), because of it is combined into staggered interting, so need to finish embedded part (302) and insert inserting between embedding hole (310) in the mode of artificial combination, and when clamping head (30) with after band (31) combines, must fixedly make both be fixed shape to suppress again, make the manufacturing process complexity, time-consuming.Because the bonded area between embedded part (302) and slotting embedding hole (310) is little, when tightening use, very easily causes clamping head (30) to come off and separate with band (31).

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides a kind of manufacturing process easy, and is with low cost, adhesive strength height, assembly, pipe clamp easy to use.

Technical solution of the present utility model is: pipe clamp is made up of clamping head, packing bolt and the band that has an inclined hole; Wherein, the clamping head lower end is formed with the both wing portions that differs in size, and big alar part is kink shape, and the terminal sunken mating face that forms, this mating face front end extension is provided with a fastening part, and little alar part is superimposed on the junction plane of big alar part, and the back is flat in engaging, and has smooth welding plane; One end of band is provided with the blocking hole, the size in this blocking hole and mating face sizableness, and after being arranged in fastening part, fasten on the mating face.

The utility model has improved the combining structure of clamping head lower end alar part and the connected structure of clamping head and band, make this pipe clamp have the combination force of easy manufacturing process and strong all around direction, make it in the process of tight bundle, do not split or phenomenon that structure comes off and separates.And, this pipe clamp zero, modular construction is simple, can distinguish independent production, need not to expend too much manpower and equipment cost.Have adhesive strength height and assembly, characteristics such as easy to use, be suitable for various high and low pressure pipeline and be extensive use of.

The utility model is described in further detail below in conjunction with drawings and Examples: consult Fig. 5, Fig. 6, shown in Figure 9, a kind of pipe clamp is by clamping head (5), packing bolt (50) and have the integrative-structure that the band (6) of inclined hole (60) is formed, wherein clamping head (5) is to bend to arcuation with a tinsel, its inside is provided with a packing bolt (50), these tinsel two ends form greatly, little both wing portions (51), (52), its big alar part (51) is kink shape, and the terminal mating face (510) of sinking that suitably forms, consult shown in Figure 8, this mating face (510) front end protrudes out and is provided with a fastening part (511), its little alar part (52) is superimposed through bending and mating face (510), and the exterior edge face, back is flat in engaging, and make both in welding the time can have a best in conjunction with the plane, big because of clamping head (5) lower end, little alar part (51), (52) be identical material, so after superimposed welding, have good closed intensity, the left and right directions that makes this place is in conjunction with very firmly forming strong combination force.Consult Fig. 5, shown in Figure 7, band (6) is one to have the metal band of suitable length, the one end is provided with inclined hole (60) through punching out, the other end offers a blocking hole (61), mating face (510) sizableness of the size in this blocking hole (61) and big alar part (51), after making this blocking hole (61) wear fastening part (511), can further fasten in the mating face (510) locates, make its fore-and-aft direction also have strong combination force, so, the utility model possessed simultaneously strong before, after, a left side, the combination force of right four direction, no matter make its packing be used in low pressure line or pressure duct, all can make delivery pipe and joint part present best driving fit locking condition, and not have the situation that causes clamping head (5) and band (6) junction to split because of the application of force is improper because of stressed excessive generation.

During use, consult shown in Figure 10, the band (6) that can carry out and get suitable length, and be sheathed on the blocking hole (61) on the band (6) on the fastening part (511) of big alar part (51) front end, the movable end of band (6) is around on delivery pipe and the joint, and this end is arranged in the clamping head (5), the inclined hole (60) on this band of rotation interlock (6) of packing bolt (50) and the junction of packing delivery pipe and joint, and reach best tight Shu Xiaoguo.
