[0023] The utility model is described in detail below with reference to the accompanying drawings Figures 1 to 5.

[0024] Embodiment: Referring to Figures 4 and 5, a hardware pipe connector comprises: a semicircular main connection block 2 and a semicircular secondary connection block 3, main connection through holes 9 are respectively provided at both ends of the main connection block 2, secondary connection through holes are respectively provided at both ends of the secondary connection block 3, a connection assembly 15 for splicing the main connection block 2 and the secondary connection block 3 is connected between the main connection through holes 9 and the secondary connection through holes, a main arc groove and a main arc sealing gasket 5 fixed to the main arc groove are provided in the middle of the main connection block 2, a secondary arc groove and a secondary arc sealing gasket 8 fixed to the secondary arc groove are provided in the middle of the secondary connection block 3, a connection structure A is provided at the end of the main arc sealing gasket 5, and a connection structure B is provided at the end of the secondary arc sealing gasket 8, when the main connection block 2 and the secondary connection block 3 are spliced, the connection structure A is connected to the connection structure B, and the main arc sealing gasket 5 and the secondary arc sealing gasket 8 are spliced ​​into an annular sealing ring.

[0025] Compared with the hardware pipe connector of the background technology, the present technical solution has a relatively simple structure and is relatively convenient to use. Before use, the connection assembly 15 is in a relaxed state, that is, the main connection block 2 can move or be spaced a certain distance relative to the auxiliary connection block 3; when connecting the pipes 1 at both ends, the main connection block 2 and the auxiliary connection block 3 are respectively placed outside one of the pipes 1, so that the end of the pipe 1 is located in the middle of the main arc-shaped sealing gasket 5 and the auxiliary annular sealing gasket, and then the end of the other pipe 1 is extended between the main connection block 2 and the auxiliary connection block 3, and is abutted or adjacent to the end of the previous pipe 1, and the ends of the two pipes 1 are both located on the inner side of the main arc-shaped sealing gasket 5 and the auxiliary arc-shaped sealing gasket 8, as shown in Figure 1; then the connection assembly 15 is tightened to abut the main connection block 2 and the auxiliary connection block 3, as shown in Figure 2. When the main connection block 2 and the auxiliary connection block 3 abut against each other, the ends of the main arc-shaped sealing gasket 5 and the auxiliary arc-shaped sealing gasket 8 also abut against each other and are connected, so that the main arc-shaped sealing gasket 5 and the auxiliary arc-shaped sealing gasket 8 are connected as a whole, that is, spliced ​​into an annular sealing ring, as shown in FIG. Figure 3 shown.

[0026] Furthermore, the main connecting through-hole 9 and the secondary connecting through-hole are both connecting through-holes, and a countersunk hole is provided at the outer end of the connecting through-hole, and the aperture of the countersunk hole is larger than the aperture of the connecting through-hole. The connecting assembly 15 includes a bolt 14, and the end of the bolt 14 is threadedly connected with an adjusting nut 13; the head of the bolt 14 is located in the countersunk hole of the main connecting through-hole 9, and the adjusting nut 13 is located in the countersunk hole of the secondary connecting through-hole.

[0027] After countersunk holes are provided at the outer ends of the connecting through-holes, the heads of the bolts 14 and the adjusting nuts 13 can be hidden in the two countersunk holes. When the main connecting block 2 and the auxiliary connecting block 3 are connected, the bolt 14 is rotated. When the bolt 14 rotates, the screw rod of the bolt 14 and the adjusting nut 13 rotate relative to each other, so that the adjusting nut 13 moves relative to the screw rod, the head of the bolt 14 abuts against the end face of the countersunk hole of the main connecting through-hole 9, and the adjusting nut 13 abuts against the end face of the countersunk hole of the auxiliary connecting through-hole, so that the main connecting block 2 and the auxiliary connecting block 3 are clamped.

[0028] As another variation of the present technical solution, the bolt 14 is replaced by a screw rod, both ends of which are threadedly connected with adjusting nuts 13, and the two adjusting nuts 13 are respectively located in the countersunk holes on both sides; by rotating the adjusting nuts 13 at both ends, the main connecting block 2 and the auxiliary connecting block 3 are brought close to and abutted against each other.

[0029] Preferably, the end of the bolt 14 is connected to a limit block, which can be bonded to the end of the bolt 14 or connected by interference fit; after the limit block is provided, the adjustment nut 13 can be prevented from being separated from the threaded rod of the bolt 14.

[0030] See Figure 4; in this embodiment, the connection structure A includes a concave hole 10 and a convex block 11 respectively arranged at both ends of the main arc-shaped sealing gasket 5, and the connection structure B includes a convex block 11 and a concave hole 10 arranged at both ends of the secondary arc-shaped sealing gasket 8. The convex block 11 on the main arc-shaped sealing gasket 5 is plugged into the concave hole 10 on the secondary arc-shaped sealing gasket 8, and the convex block 11 on the secondary arc-shaped sealing gasket 8 is plugged into the concave hole 10 on the main arc-shaped sealing gasket 5.

[0031] The two ends of the main arc-shaped sealing gasket 5 are provided with a convex block 11 and a concave hole 10, respectively, and the two ends of the auxiliary arc-shaped sealing gasket 8 are provided with a corresponding concave hole 10 and a convex block 11, respectively; when connected, the convex block 11 is plugged into the corresponding concave hole 10 and connected with a rigid fit. Thus, the main arc-shaped sealing gasket 5 and the auxiliary arc-shaped sealing gasket 8 are spliced ​​into an annular sealing ring.

[0032] As a structural variation, the connection structure A includes recessed holes 10 provided at both ends of the main arc-shaped sealing gasket 5 , and the connection structure B includes protrusions 11 provided at both ends of the secondary arc-shaped sealing gasket 8 . When the main connection block 2 and the secondary connection block 3 are spliced, the protrusions 11 are inserted into the recessed holes 10 .

[0033] To facilitate the splicing of the main arc-shaped sealing gasket 5 and the secondary arc-shaped sealing gasket 8, the technical solution sets the connection structure A as a recessed hole 10, and the connection structure B is set as a convex block 11 that matches the recessed hole 10. The convex block 11 is connected to the recessed hole 10 by interference fit or matching connection.

[0034] Furthermore, the outer end of the protrusion 11 is arranged in a trapezoidal shape, and the inner end of the protrusion 11 is arranged in a rectangular shape; and the concave hole 10 is arranged in a rectangular shape.

[0035] The outer end of the protrusion 11 is set to be a trapezoid. When the protrusion 11 is inserted into the concave hole 10, since the cross-sectional area of ​​the outer end of the protrusion 11 is smaller than the cross-sectional area of ​​the concave hole 10, the outer end of the protrusion 11 can be smoothly inserted into the concave hole 10. It can be avoided that when the main connection block 2 is connected with the external connection block, the protrusion 11 cannot be smoothly inserted into the concave hole 10 due to factors such as errors, thereby affecting the connection between the main connection block 2 and the auxiliary connection block 3.

[0036] See Figures 3, 4 and 5; main side arc grooves 12 are respectively provided on both sides of the main arc groove, and secondary side arc grooves are respectively provided on both sides of the secondary arc groove. A main side sealing gasket 6 is provided in the main side arc groove 12, and a secondary side sealing gasket 7 is provided in the secondary side arc groove. The main side sealing gasket 6 and the corresponding secondary side sealing gasket 7 are spliced ​​into a side sealing ring.

[0037] To further seal the pipeline 1, the present technical solution provides a main side sealing gasket 6 and a secondary side sealing gasket 7 on both sides of the main connection block 2 and the secondary connection block 3 respectively; when connected, they are spliced ​​into side sealing rings; the two side sealing rings form a seal for the pipeline 1 to improve the sealing degree.

[0038] Referring to Figures 4 and 5, preferably, one end of the main side sealing gasket 6 protrudes from the main side arc groove 12, and the other end of the main side sealing gasket 6 is located in the main side arc groove 12; one end of the secondary side sealing gasket 7 protrudes from the secondary side arc groove, and the other end of the secondary side sealing gasket 7 is located in the secondary side arc groove; when the main connecting block 2 and the secondary connecting block 3 are connected, one end of the main side sealing gasket 6 is inserted into the corresponding secondary side arc groove and abuts against the other end of the secondary side sealing gasket 7, and one end of the secondary side sealing gasket 7 is inserted into the main side arc groove 12 and abuts against the other end of the main side sealing gasket 6.

[0039] When the main side sealing gasket 6 and the secondary side sealing gasket 7 are spliced, for the convenience of description, the splicing surface of the main side sealing gasket 6 and the secondary side sealing gasket 7 is called the first splicing surface; the splicing surface of the main connecting block 2 and the secondary connecting block 3 is called the second splicing surface; the splicing surface of the main arc-shaped sealing gasket 5 and the secondary arc-shaped sealing gasket 8 is the third splicing surface; if two or more of the first splicing surface, the second splicing surface and the third splicing surface are located on the same surface, when vibration occurs, the three splicing surfaces are likely to leak at the same time, and the sealing degree is low. The first splicing surface, the second splicing surface and the third splicing surface are staggered, and the probability of leakage of the three splicing surfaces at the same time is very low; the sealing degree can be effectively improved. Therefore, in the present technical solution, one end of the main side sealing gasket is protruding, and the other end is located in the main side arc-shaped groove 12.

[0040] Referring to FIG. 4 and FIG. 5 , preferably, of the ends of the two main-side sealing pads 6 on the same side, one end protrudes out of the corresponding main-side arc groove 12 , and the other end is located in the corresponding main-side arc groove 12 .

[0041] The two main side sealing pads 6 are staggered to further improve the sealing degree.

[0042] Furthermore, a limiting baffle 4 is provided at the middle of the inner side surface of the main arc-shaped sealing pad 5 and the secondary arc-shaped sealing pad 8 .

[0043] When connecting the pipeline 1, the end of the pipeline 1 should be located in the middle of the main arc-shaped sealing gasket 5 and the secondary arc-shaped sealing gasket 8. However, in actual operation, it is generally difficult to accurately position the end of the pipeline 1, and generally only an approximate position can be placed; even the outer end close to the main arc-shaped sealing gasket 5 has a small contact area with the pipeline 1, which is very unfavorable for sealing the pipeline 1; in order to facilitate the adjustment of the relative position of the pipeline 1 and the main arc-shaped sealing gasket 5 and the secondary arc-shaped sealing gasket 8, a protruding limit baffle 4 is provided in the middle of the inner side surface of the main arc-shaped sealing gasket 5 and the secondary arc-shaped sealing gasket 8, until the pipeline 1 is against the limit baffle 4 when the main connecting block 2, the secondary connecting block 3 or the pipeline 1 is moved.

[0044] The above contents are only preferred embodiments of the utility model. For ordinary technicians in this field, according to the concept of the utility model, there will be changes in the specific implementation method and application scope. The content of this specification should not be understood as a limitation on the utility model.
