Description

Technical Field

[0001] This utility model relates to the field of high neck flange technology, specifically to a high load-bearing stainless steel high neck flange that can be quickly connected. Background Technology

[0002] High neck flanges are a common type of flange connection, mainly used in pipeline systems with high pressure, high temperature, or high sealing requirements.

[0003] A search revealed that the Chinese patent "A High-Neck Flange Capable of Rapid Connection" (CN221839128U) discloses this utility model, which relates to the field of flange technology and aims to solve the problem of time-consuming and laborious flange connection. The key technical points are: it includes a first flange and a second flange; the first flange has positioning plates hinged to its upper and lower sides, with symmetrically installed snap-fit ​​components inside the positioning plates; the second flange has U-shaped fixing blocks installed on its upper and lower sides, with two symmetrical sliding tracks on the inner sides of the U-shaped fixing blocks, and multiple slots on the tracks; the snap-fit ​​ends of the snap-fit ​​components are adapted to the slots. This utility model, through the snap-fit ​​components on the positioning plates, allows the positioning plates to be snapped into the slots of the U-shaped fixing blocks, thereby initially positioning the first and second flanges, ensuring that the first and second flanges are tightly fitted together and that the bolt holes on the first and second flanges are aligned, thus facilitating rapid flange connection, saving time and increasing efficiency.

[0004] Although the aforementioned high neck flanges can achieve a pre-positioning effect by using snap-fit ​​parts and slots, the positioning effect can only be achieved when each snap-fit ​​part is aligned with the slot. Therefore, when encountering high neck flanges of different thicknesses, the snap-fit ​​parts at the fixed positions may not be able to perfectly match the designated slots. There are problems such as insufficient distance between the snap-fit ​​part and the previous slot, resulting in failure to snap-fit, and gaps between the two high neck flanges after snap-fitting with the next slot. Furthermore, the entire structure is set on the surface of the high neck flange and is a non-removable design, so it is prone to damage and rust when exposed to the outside for a long time, resulting in a short service life.

[0005] Based on this, this utility model designs a high-load-bearing stainless steel high-neck flange that can be quickly connected to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high load-bearing stainless steel high neck flange that can be quickly connected.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-load-bearing stainless steel high-neck flange that can be quickly connected includes two flange bodies, and the surfaces of the flange bodies are provided with a plurality of mounting holes in a ring array.

[0009] A connecting assembly disposed between the surfaces of two flange bodies;

[0010] The connecting assembly includes a snap-fit ​​shell and a snap-fit ​​block respectively disposed above the two flange bodies, and a support plate is provided below the snap-fit ​​shell and the snap-fit ​​block;

[0011] Furthermore, the connecting assembly also includes a connecting plate disposed on the opposite side of the snap-fit ​​housing and the snap-fit ​​block, wherein the side of the connecting plate closest to the flange body contacts the flange body.

[0012] Furthermore, the snap-fit ​​block has a V-shaped design and is horizontally inserted into the snap-fit ​​shell;

[0013] Furthermore, the inner wall of the snap-fit ​​shell is provided with a friction plate, and the side of the snap-fit ​​block is provided with an abutment block, the surface of which contacts the friction plate;

[0014] Furthermore, the surface of the connecting plate is provided with an opening, and a lead screw is installed in the opening of the connecting plate through a bearing. A threaded sleeve is threadedly connected to the surface of the lead screw, and a support rod is movably connected to the surface of the threaded sleeve through a rotating shaft. The other end of the support rod is movably connected to the support plate through a rotating shaft.

[0015] Furthermore, the support plate is designed in an arc shape, and four support plates are arranged in a circular array with the lead screw as the center, and the support plates correspond to the mounting holes;

[0016] Furthermore, the surface of the support plate is provided with a rubber sheet, and the surface of the rubber sheet is in contact with the inner wall of the mounting hole;

[0017] Furthermore, the surface of the connecting plate is provided with a cross-shaped sliding groove, and a sliding block is slidably connected in the cross-shaped sliding groove. The side of the sliding block near the support plate is fixedly connected to the support plate. Beneficial effects

[0018] 1. By setting the snap-fit ​​housing and snap-fit ​​block of the connecting component, the inner wall of the snap-fit ​​housing is provided with friction pads, and the snap-fit ​​block is designed in a V shape with abutment blocks on the edge. When the two flange bodies are aligned with each other, the snap-fit ​​block is inserted into the snap-fit ​​housing, and its two ends abut against the inner wall of the snap-fit ​​housing respectively. This can make the snap-fit ​​block and the snap-fit ​​housing form a mutual pulling effect, which can prevent the two flange bodies from loosening and achieve the effect of pre-positioning the flange bodies. This can effectively improve the efficiency of personnel connecting the two flange bodies.

[0019] 2. By setting the lead screw and strut in the connecting assembly, the expansion diameter of the four support plates can be adjusted, which enables the device to be adapted to flange bodies of different models and mounting hole diameters, improving the overall adaptability of the connecting assembly. At the same time, after the flange body is pre-treated, the entire device can be disassembled and recycled, achieving the effect of recycling. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A high-load-bearing stainless steel high-neck flange that can be quickly connected includes two flange bodies 1, and the surface of the flange body 1 is provided with multiple mounting holes in a ring array.

[0030] When personnel need to assemble two flange bodies 1, they should first ensure that the holes of the two flange bodies 1 are aligned.

[0031] Connection component 2 is disposed between the surfaces of the two flange bodies 1;

[0032] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the connecting assembly 2 includes a snap-fit ​​shell 203 and a snap-fit ​​block 202 respectively disposed above the two flange bodies 1, and a support plate 206 is disposed below the snap-fit ​​shell 203 and the snap-fit ​​block 202; the connecting assembly 2 also includes a connecting plate 201 respectively disposed on the opposite side of the snap-fit ​​shell 203 and the snap-fit ​​block 202, and the side of the connecting plate 201 close to the flange body 1 contacts the flange body 1;

[0033] Then, the workers can place the two connecting plates 201 in the connecting assembly 2 on opposite sides of the two flange bodies 1, and keep the support plate 206 below the surface of the connecting plate 201 inserted into the mounting hole. At this time, the workers can use external tools to turn the screw 208. When the screw 208 rotates, the threaded sleeve 209 will slide horizontally on its surface. At this time, the support rod 210 will adjust its angle as the position of the threaded sleeve 209 moves. Since the support plate 206 is vertically limited by the slide block 211 and the cross slide groove 205, the support plate 206 will be supported by the support rod 210 and move closer to the inner wall of the mounting hole. At this time, the diameter of the cylinder formed by the four support plates 206 will be the same as the diameter of the mounting hole. After the surface of the support plate 206 contacts the inner wall of the mounting hole, the workers will move the two flange bodies 1 closer to each other.

[0034] At this time, the snap-fit ​​block 202 will be inserted into the snap-fit ​​housing 203, and the abutment block 204 on the side of the snap-fit ​​block 202 will also abut against the friction plate on the inner wall of the snap-fit ​​housing 203. Thus, the friction generated between the support plate 206 and the inner wall of the mounting hole can be used for positioning. Finally, the operator uses an external tool to tighten the screw 208, so that the four support plates 206 are further expanded and fit against the inner wall of the mounting hole. This can promote the tightness of the connection between the connecting component 2 and the mounting hole and improve the pre-connection effect of the two flange bodies 1.

[0035] In this embodiment of the utility model, the snap-fit ​​block 202 is designed in a V shape and is horizontally inserted into the snap-fit ​​shell 203;

[0036] When the snap-fit ​​block 202 is inserted into the snap-fit ​​housing 203, the abutment block 204 on the side of the snap-fit ​​block 202 will also abut against the friction plate on the inner wall of the snap-fit ​​housing 203, so that the positioning can be achieved by the friction between the support plate 206 and the inner wall of the mounting hole.

[0037] When subsequent personnel need to separate the snap-fit ​​block 202 from the snap-fit ​​shell 203, they only need to use a clamping tool, such as pliers, to insert into the snap-fit ​​shell 203 and clamp the tip of the V-shaped snap-fit ​​block 202. At this time, the angle of the V-shaped snap-fit ​​block 202 will be reduced, and its two ends will no longer contact the inner wall of the snap-fit ​​shell 203.

[0038] Because the locking block 202 has a V-shaped design, it can only be inserted and will not loosen or fall off on its own unless it is moved by external force.

[0039] In this embodiment of the utility model, the inner wall of the snap-fit ​​shell 203 is provided with a friction plate, and the side of the snap-fit ​​block 202 is provided with an abutment block 204, the surface of the abutment block 204 being in contact with the friction plate.

[0040] By setting a friction plate and an abutment block 204, the friction plate has a wear-resistant coating on its surface, and the abutment block 204 is composed of multiple trapezoidal blocks. When the abutment block 204 contacts the friction plate, a certain frictional force is generated. At this time, the locking block 202 and the locking shell 203 can use this frictional force to limit each other.

[0041] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, the surface of the connecting plate 201 is provided with an opening, and a lead screw 208 is provided in the opening of the connecting plate 201 through a bearing. A threaded sleeve 209 is threadedly connected to the surface of the lead screw 208, and a support rod 210 is movably connected to the surface of the threaded sleeve 209 through a rotating shaft. The other end of the support rod 210 is movably connected to the support plate 206 through a rotating shaft.

[0042] First, the workers place the two connecting plates 201 in the connecting assembly 2 on opposite sides of the two flange bodies 1, and keep the support plate 206 below the surface of the connecting plate 201 inserted into the mounting hole;

[0043] At this point, the operator can use external tools to turn the lead screw 208. When the lead screw 208 rotates, the threaded sleeve 209 will slide horizontally on its surface. At this time, the support rod 210 will adjust its angle as the position of the threaded sleeve 209 changes. Since the support plate 206 is vertically limited by the slide block 211 and the cross slide groove 205, the support plate 206 will be supported by the support rod 210 and move closer to the inner wall of the mounting hole. At this time, the diameter of the cylinder formed by the four support plates 206 will be the same as the diameter of the mounting hole. After the surface of the support plate 206 contacts the inner wall of the mounting hole, the operator will move the two flange bodies 1 closer to each other.

[0044] When the entire device needs to be dismantled later, the screw 208 only needs to be turned in the opposite direction using an external tool. At this time, the support plate 206 will be retracted and no longer adhere to the inner wall of the mounting hole. The staff can then pull the connecting component 2 out of the mounting holes of the two flange bodies 1 and retract it.

[0045] In this embodiment of the utility model, the support plate 206 is arc-shaped, and four support plates 206 are arranged in a circular array with the lead screw 208 as the center. The support plates 206 correspond to the mounting holes.

[0046] In this embodiment of the utility model, a rubber sheet 207 is provided on the surface of the support plate 206, and the surface of the rubber sheet 207 is in contact with the inner wall of the mounting hole. The rubber sheet 207 is made of rubber. When the support plate 206 compresses the rubber sheet 207, the rubber sheet 207 will use its flexible characteristics to provide movement space for the support plate 206, so as to help the personnel to adjust the support plate 206 by turning the screw 208 a second time. At the same time, the contact between the surface of the rubber sheet 207 and the inner wall of the mounting hole will generate a certain friction force, which can prevent the support plate 206 from slipping off the inner wall of the mounting hole.

[0047] In this embodiment of the utility model, a cross groove 205 is provided on the surface of the connecting plate 201, and a slide block 211 is slidably connected in the cross groove 205. The side of the slide block 211 near the support plate 206 is fixedly connected to the support plate 206.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
