Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a detachable flange. Background Art

[0002] A flange is a ring-shaped part used to connect pipes, valves, pumps, and other equipment or components. It typically has bolt holes, allowing fasteners like bolts and nuts to securely connect components. Flanges play a crucial role in industrial production, and their design and use are directly related to the safety and stability of mechanical systems.

[0003] When the coil handles a large water flow, a relatively large flange is required. The outer diameter of the DN100 national standard flange reaches 220mm, and the outer diameter of the DN125 national standard flange reaches 250mm. In this way, the panel of the air-conditioning box needs to have a relatively large hole. The processing of large holes is difficult and affects the appearance of the panel of the air-conditioning box. Therefore, a detachable flange structure is required to allow the coil interface to pass through the box plate and then install the flange to avoid the opening of large holes. Utility Model Content

[0008] A connecting piece is installed at the connection between the first sub-disc and the second sub-disc. A splicing connecting rod that defines the connection position of the first sub-disc and the second sub-disc is fixed to the side of the connecting piece. A No. 1 fastener is threadedly connected to the side of the connecting piece away from the splicing connecting rod for tightening the splicing position of the first sub-disc and the second sub-disc.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 、 2 As shown in , 3, 4, and 5, the utility model provides a technical solution: a detachable flange, comprising: a second sub-disc 2 and a first sub-disc 1, the second sub-disc 2 and the first sub-disc 1 are both plates with semi-circular structures, and the second sub-disc 2 has a limiting groove 3 symmetrically provided on one side close to the center of the circle; the first sub-disc 1 is spliced on one side of the second sub-disc 2, and a limiting block 4 is fixedly connected to one side of the first sub-disc 1 and interlocked with the limiting groove 3, and the first sub-disc 1 and the second sub-disc 2 can be spliced to form a complete flange; the connecting member 7 is installed at the connection between the first sub-disc 1 and the second sub-disc 2, and the connecting member 7 is an inverted L-shaped structure, and a splicing connecting rod 8 is fixedly connected to the side of the connecting member 7 for limiting the connection position of the first sub-disc 1 and the second sub-disc 2, and a No. 1 fastener 9 is threadedly connected to the side of the connecting member 7 away from the splicing connecting rod 8, which is used to tighten the splicing position of the first sub-disc 1 and the second sub-disc 2.

[0024] It should be noted that, after the coil interface of the present invention passes through the box plate, the first sub-disc 1 and the second sub-disc 2 are placed on the outside of the coil interface, so that the limit block 4 is inserted into the limit groove 3. At this time, the first sub-disc 1 and the second sub-disc 2 form a complete circular ring structure, and then the splicing connecting rods 8 on the side of the connecting piece 7 are respectively inserted into the splicing holes 5 located near the connection position in the first sub-disc 1 and the second sub-disc 2, and then the No. 1 fastener 9 on one side of the connecting piece 7 is tightened. The No. 1 fastener 9 is located between the two splicing connecting rods 8. When tightening, the No. 1 fastener 9 is pressed on the connecting gap between the first sub-disc 1 and the second sub-disc 2, thereby squeezing and fixing the first sub-disc 1 and the second sub-disc 2 on the inner side of the connecting piece 7, thereby completing the splicing.

[0025] See also Figure 1 As shown, the limiting block 4 and the limiting groove 3 are both isosceles trapezoidal structures.

[0026] It should be noted that the isosceles trapezoidal structure of the present invention is trumpet-shaped and has multiple corners. After being fully embedded, the corners of the trapezoid are self-locked with each other to enhance the stability of the connection. The first sub-disc 1 and the second sub-disc 2 on both sides separate to both sides when subjected to external force.

[0027] See also Figure 1 、 2As shown in , 4 , corresponding positions of the first sub-disc 1 and the second sub-disc 2 are provided with splicing holes 5 for use with the splicing connecting rods 8 , and the sides of the first sub-disc 1 and the second sub-disc 2 are provided with multiple connecting holes 6 .

[0028] It should be noted that the splicing holes 5 of the utility model are symmetrical about the connection gap between the first sub-disc 1 and the second sub-disc 2. When the limit groove 3 and the limit block 4 are assembled, the two splicing holes 5 correspond to the two splicing connecting rods 8. By inserting the splicing connecting rods 8 into the splicing holes 5, the splicing position of the first sub-disc 1 and the second sub-disc 2 can be reinforced again to increase the stability of the connection. The connecting hole 6 is used to connect the two splicing flanges by bolts, and the pipeline is connected by tightening and fixing the bolts.

[0029] See also Figure 5 As shown, the connecting member 7 includes an arc-shaped plate 13, one end of the arc-shaped plate 13 is fixedly connected to the short side plate 11, and the end of the arc-shaped plate 13 facing away from the short side plate 11 is fixedly connected to the long side plate 12, the splicing connecting rod 8 is fixed to the side of the short side plate 11, and the No. 1 fastener 9 is threadedly connected to the long side plate 12, and one side of the long side plate 12 is threadedly connected to the No. 2 fastener 14, the No. 2 fastener 14 is opposite to the splicing of the limit groove 3 and the limit block 4, and the No. 1 fastener 9 and the No. 2 fastener 14 are both hexagon socket bolts.

[0030] It should be noted that the present invention is provided with two splicing connecting rods 8 and both are fixed to the short side plates 11. When the splicing connecting rods 8 are inserted into the splicing holes 5, the splicing connecting rods 8 limit the first sub-disc 1 and the second sub-disc 2 to prevent them from separating left and right. At the same time, the short side plates 11 provide support surfaces for the sides of the first sub-disc 1 and the second sub-disc 2 to prevent the two from being misaligned. Then the No. 1 fastener 9 on one side of the long side plate 12 is squeezed on the connecting gap between the first sub-disc 1 and the second sub-disc 2, and the first sub-disc 1 and the second sub-disc 2 are squeezed on one side of the short side plate 11, so that the first sub-disc 1 and the second sub-disc 2 are squeezed and fixed between the short side plate 11 and the No. 1 fastener 9, and then the No. 2 fastener 14 is tightened so that the No. 2 fastener 14 is squeezed and stuck at the corner where the limit groove 3 and the limit block 4 are spliced, thereby enhancing the stability of the connection and preventing misalignment.
