Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a necked flange with impact resistance. Background Technique

[0002] A necked flange is a common pipe connector, which is mainly used for connection and sealing in a pipe system. The main feature of this flange is that there is a protruding neck in the central part of the flange disc, and this neck can be directly welded to the pipe to form a firm connection.

[0003] The existing authorized publication number is CN215258514U, which discloses an impact-resistant steel-lined plastic blind flange, including a steel blind flange, a crack-resistant outer shell and a support structure. The steel blind flange is fixedly arranged in the inner cavity of the crack-resistant outer shell, and the crack-resistant outer shell is a component made of a polypropylene material. The thickness of the crack-resistant outer shell is 3-7 mm. This setting makes the blind flange not only have a small mass, but also good toughness, high mechanical strength, strong impact resistance, and is not easy to break, ensuring the use safety of the steel-lined plastic blind flange. A fastener is arranged in the through hole, and the fastener is a component made of a polypropylene material. This setting enables the fastener to pass through the through hole, thereby fastening the steel blind flange and the crack-resistant outer shell together. This setting not only increases the overall mechanical strength and impact resistance of the product, but also reduces the trapped air in the product, further strengthening the tightness of the combination of the two materials.

[0004] Adopting the above technical solution, although the crack-resistant outer shell is used to protect the flange against impact, when the flange falls from a high floor, the impact force is extremely large, and thus the crack-resistant outer shell may also crack. In addition, the internal flange may be strongly squeezed between the outer wall of the flange and the inner wall of the crack-resistant outer shell due to the impact force generated by the high-altitude fall, resulting in damage. Therefore, we provide a necked flange with impact resistance. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model.

[0023] The utility model provides a technical solution: as Figures 1-4As shown in the figure, in this embodiment, an impact-resistant necked flange includes: a buffer mechanism 1, the buffer mechanism 1 includes a flange body 11, a plurality of buffer grooves 15 annularly arranged on the outer side of the flange body 11, a buffer rod 12 is arranged in each of the plurality of buffer grooves 15, a buffer spring 13 is arranged outside each of the plurality of buffer rods 12, a buffer pad 14 is arranged at one end of each of the plurality of buffer rods 12 away from the flange body 11, the outer side of the buffer rod 12 near one end of the flange body 11 is slidably connected to the inner wall of the buffer groove 15, one end of the buffer rod 12 away from the flange body 11 passes through the buffer spring 13 and is fixedly connected to one side of the buffer pad 14, one end of the buffer spring 13 is fixedly connected to the side of the buffer pad 14 near the buffer rod 12, the other end of the buffer spring 13 is fixedly connected to the outer side of the flange body 11, a buffer elastic sheet 16 is arranged in each of the plurality of buffer grooves 15, one end of the buffer rod 12 away from the buffer pad 14 is fixedly connected to one end of the buffer elastic sheet 16, the other end of the buffer elastic sheet 16 is fixedly connected to the side of the inner wall of the buffer groove 15 away from the buffer pad 14, elastic members 17 are arranged on both sides near the buffer rod 12 between the plurality of buffer pads 14 and the flange body 11, a plurality of installation grooves 18 are annularly arranged on the top of the flange body 11, installation members 19 are arranged in each of the plurality of installation grooves 18, one end of the elastic member 17 is fixedly connected to the outer side of the flange body 11, the other end of the elastic member 17 is fixedly connected to the side of the buffer pad 14 near the flange body 11, the outer side of the installation member 19 is threadedly connected to the inner wall of the installation groove 18, a plurality of limit holes 110 are arranged on the outer side of each of the plurality of installation members 19, and a limit mechanism 2 is arranged on the outer side of the flange body 11.

[0024] In this embodiment, when the flange falls from a higher floor, the buffer pad 14 will first contact the ground, and then a strong impact force will be generated. This impact force will be transmitted to the elastic member 17, the buffer spring 13, and the buffer rod 12. Then, the elastic member 17 and the buffer spring 13 will contract and deform under the impact force, and the buffer rod 12 will be recessed into the buffer groove 15 under the impact force, squeezing the buffer elastic sheet 16. Then, the buffer elastic sheet 16 will contract and deform under the extrusion force. Therefore, through the buffer pad 14, the buffer spring 13, the buffer rod 12, the buffer elastic sheet 16, and the elastic member 17, the external impact force can be effectively absorbed and dispersed, thereby reducing the impact force on the flange, improving its impact resistance, and further extending the service life of the flange.

[0025] As Figures 1-4As shown in the figure, the limiting mechanism 2 includes a mounting block 21. One side of the mounting block 21 is fixedly connected to the outer side of the flange body 11. The side of the mounting block 21 away from the flange body 11 is in contact with the side of the lever 22 close to the mounting block 21. One end of a clamping post 23 is movably connected to the inside of the lever 22. The other end of the clamping post 23 passes through the inner ring of a spring 24, the mounting block 21, and a clamping groove formed on the outer side of the flange body 11 and is clamped in a limiting hole 110. One end of the spring 24 is fixedly connected to the inner wall of the mounting block 21 close to the lever 22, and the other end of the spring 24 is fixedly connected to the inner wall of the mounting block 21 away from the lever 22.

[0026] In this embodiment, when the flange body 11 is fixedly installed with other workpieces, in order to ensure that their connection points will not become loose due to external factors, the lever 22 can be toggled. After one side of the lever 22 rubs and squeezes against the mounting block 21, it will pull the clamping post 23 to move in the direction of the lever 22. When the clamping post 23 moves, it will squeeze the spring 24. Therefore, the spring 24 will contract and deform. After the flange body 11 and the workpiece are installed through the mounting member 19, the released lever 22 will cause the spring 24 to lose the extrusion force and release the elastic force to push the clamping post 23 to be clamped in a preset clamping groove outside the mounting member 19. Thus, the mounting member 19 will be limited in the mounting groove 18, preventing the mounting member 19 from becoming loose in the mounting groove 18 due to external impact.

[0027] The present utility model provides an impact-resistant necked flange, and the specific working principle is as follows:

[0028] When the flange body 11 falls from a relatively high floor, in order to reduce the impact on the equipment, the buffer pad 14 will first contact the ground. This contact will generate a strong impact force, which will be transmitted to the elastic member 17, the buffer spring 13, and the buffer rod 12. After being subjected to the impact force, the elastic member 17 and the buffer spring 13 will contract and deform because they have elastic characteristics and can absorb and disperse the energy of the impact force. Similarly, after being subjected to the impact force, the buffer rod 12 will also sink into the buffer groove 15 and squeeze the buffer spring piece 16. After being subjected to the squeezing force, the buffer spring piece 16 will also contract and deform because of its elastic characteristics, which can further absorb and disperse the energy of the impact force. When it is necessary to fixedly install the flange body 11 with other workpieces, the lever 22 can be toggled. After one side of the lever 22 rubs and squeezes against the mounting block 21, it will pull the clamping post 23 to move in the direction of the lever 22. When the clamping post 23 moves, it will squeeze the spring 24. Therefore, the spring 24 will contract and deform. After the flange body 11 and the workpiece are installed through the mounting member 19, the released lever 22 will cause the spring 24 to lose the extrusion force and release the elastic force to push the clamping post 23 to be clamped in a preset clamping groove outside the mounting member 19, and the mounting member 19 will be limited in the mounting groove 18.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
