     The pipe clamp provided in this embodiment is described by taking two positioning protrusions as examples. Referring to  FIG. 2 , a first coupling section  11  is provided with a first positioning protrusion  101 , and a second coupling section  12  is provided with a second positioning protrusion  102 . 
     The first positioning protrusion  101  is integrally formed with the first coupling section  11 , and the second positioning protrusion  102  is integrally formed with the second coupling section  12 . The first positioning protrusion  101  and the first coupling section  11  are integrally cast, and the second positioning protrusion  102  and the second coupling section  12  are integrally cast to ensure the stability of the first positioning protrusion  101  and the second positioning protrusion  102 .

The second connecting mechanism includes a second bolt  106 , a third bolt hole  107  arranged at the other end of the first coupling section  11  and a fourth bolt hole  108  arranged at the other end of the second coupling section  12 . The second bolt  106  passes through the third bolt hole  107  and the fourth bolt hole  108  to realize the connection of the other end of the first coupling section  11  and the other end of the second coupling section  12 . That is, both ends of the first coupling section  11  and the second coupling section  12  are connected by a screw connection, which is simple and reliable. 
     Referring to  FIGS. 1-4 , the pipe clamp  100  with double-bolt structure provided by the embodiment can be a rigid pipe clamp, and the connection of the first coupling section  11  and the second coupling section  12  is cooperatively connected through a mutually cooperated concave-convex structure  140 . 
     Referring to  FIGS. 6-10 , the pipe clamp  100  with the double-bolt structure provided in this embodiment is a flexible pipe clamp, and the connection of the first coupling section  11  and the second coupling section  12  is an inclined port connection, that is, the connection of the first coupling section  11  and the second coupling section  12  is provided with a mutually cooperated inclined port structure  140 .

The second connecting mechanism includes a first separated pin  109  and a second separated pin  110  respectively extending from both sides of the other end of the first coupling section  11 , and a separated column connector  111  extending from the other end of the second coupling section  12 ; a separated column  112  is connected to the separated column connector  111 , and the separated column connector  111  extends and inserts between the first separated pin  109  and the second separated pin  110  so that the separated column  112  is against the first separated pin  109  and the second separated pin  110 . The ends of the first separated pin  109  and the second separated pin  110  are provided with an arc-shaped surface matching the column  112 , and the separated column  112  is against the arc-shaped surface. That is, one end of the first coupling section  11  is connected to one end of the second coupling section  12  with screws; and the other end of the first coupling section  11  is connected to the other end of the second coupling section  12  with pins. This connection can effectively improve the assembly efficiency. 
     One side of the outer surface of the first coupling section  11  is provided with a first reinforcing rib  113  connected with the first separated pin  109 ; the other side of the outer surface of the first coupling section  11  is provided with a second reinforcing rib  114  connected with the second separated pin. The first reinforcing rib  113  and the first separated pin  109  are integrally formed; the second reinforcing rib  114  is integrally formed with the second separated pin  110 . A third reinforcing rib  115  and a fourth reinforcing rib  116  are respectively arranged on both sides of the outer surface of the second coupling section  12 . The design of the reinforcing ribs on the first coupling section and the second coupling section can transmit the stress when the pipe clamp is locked to the other separated pin connectors and the other separated column connectors, reducing the stress concentration of the pipe clamp, and saving more materials and giving more effective play to its performance compared with the way of strengthening the strength by increasing the thickness. 
     Referring to  FIGS. 5, 8 and 14 , both sides of the inner surface of the first coupling section  11  are provided with a first arc segment  117  that is in contact with the pipe fitting.

The third radius c is greater than the fourth radius d by about 1-5 mm. 
     When the first coupling section  11  and the second coupling section  12  are bridged on the end-to-end pipe fittings, the inner part of the first coupling section  11  and the second coupling section  12  is formed in a nearly circular structure integrated closely with the pipe fittings fit. Since the contact part of the first coupling section  11  and the second coupling section  12  in contact with the pipe fittings are both semi elliptical-shaped, the enclosed shape is an ellipse, which make the fastening force at the time of connecting the two ends of the first coupling section  11  and the second coupling section  12  generate a centripetal deformation force through the lever torque produced by the cooperation of the longer radius and the shorter radius of the ellipse, so as to hold the pipe fittings tightly and make the inner walls of the first coupling section  11  and the second coupling section  12  fit the pipe fittings better. 
     Referring to  FIGS. 16-18 , the pipe clamp  100  provided by this embodiment includes a first coupling section and a second coupling section, which are used to fix the pipe fittings end-to-end together; one end of the first coupling section and one end of the second coupling section are connected through a first connecting mechanism, and the other end of the first coupling section and the other end of the second coupling section are connected through a second connecting mechanism; two positioning protrusions  119  are arranged on the inner wall of the first coupling section  11 , and two positioning protrusions are arranged on the inner wall of the second coupling section. The two positioning protrusions  119  of the first coupling section  11  are respectively arranged at the positions close to the end of the inner wall of the first coupling section  11 . Similarly, the two positioning protrusions of the second coupling section are respectively arranged at the positions close to the end of the inner wall of the second coupling section. The two positioning protrusions of the first coupling section and the two positioning protrusions of the second coupling section are symmetrical. The number and distribution of positioning protrusions can be set according to actual needs. 
     Referring to  FIG. 19 , the pipe clamp  100  provided by the embodiment includes a first coupling section and a second coupling section, which are used to fix the pipe fittings together end-to-end; one end of the first coupling section is screwed to one end of the second coupling section, and the other end of the first coupling section is screwed to the other end of the second coupling section; a first positioning protrusion  101  is arranged at the geometric center of the inner wall of the first coupling section  11 , two positioning protrusions  119  are arranged close to the end, a second positioning protrusion is arranged at the geometric center of the inner wall of the second coupling section, and two positioning protrusions are arranged close to the end. The pipe fittings are firmly and reliably positioned by setting a positioning protrusion for positioning the pipe fittings on the inner walls of the first coupling section and the second coupling section in the pipe clamp  100  provided in this embodiment, which can effectively save materials and reduce production costs. 
     Referring to  FIGS. 20 and 22 , the second embodiment of the invention provides a pipe clamp assembly  200 , including the pipe clamp  100  above and a sealing member  21  in cooperation with the pipe clamp  100 ; 
     The sealing member  21  is provided with positioning grooves matching the positioning protrusions. 
     The main body of the sealing member  21  is a circular ring structure, and the shape and number of positioning grooves are matched with the shape and number of positioning protrusions of the pipe clamp  100 . Referring to  FIGS. 1 and 2 , the first coupling section  11  of the pipe clamp  100  is provided with a first positioning protrusion  101 , the second coupling section  12  is provided with a second positioning protrusion  102 , and the structure of the matched sealing member  21  is shown in  FIG. 23 . The sealing member  21  is provided with a first positioning groove  201  matching the first positioning protrusion  101  and a second positioning groove  201  matching the second positioning protrusion  102 . The first positioning groove  201  and the second positioning groove  202  are symmetrical, the shape, size, depth and setting position of the first positioning groove  201  adapt to the first positioning protrusion  101 , and the shape, size, depth and setting position of the second positioning groove  202  adapt to the second positioning protrusion  102 . The depths of the first positioning groove  101  and the second positioning groove  102  are 2 mm-10 mm. 
     The sealing member  21  is used to prevent the fluid in the pipe fitting from leaking. 
     Referring to  FIG. 24 , a pair of notches  120  are formed at the connection of the first coupling section  11  and the second coupling section  12 . When the first coupling section  11  and the second coupling section  12  are in a predetermined spacing relationship, the notch  120  provides a gap for inserting the end of the pipe fitting into the space between the first coupling section  11  and the second coupling section  12 .
