[0021] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 3 The utility model provides an embodiment: a necked riser structure, including a riser body 1, a protective device body 4 is provided on the outside of the riser body 1, and connecting ports 5 are opened at four ends of the inside of the protective device body 4, and a first connecting block 6 is provided inside the connecting port 5, and the outside of the first connecting block 6 is slidably connected to the inside of the protective device body 4, and one end of the first connecting block 6 is externally fixedly connected to a clamping block 7, and the other end of the first connecting block 6 is externally fixedly connected to a second connecting block 8, and the outside of the clamping block 7 is tightly attached to the outside of the riser body 1, and multiple second connecting blocks 8 are internally provided with elastic bands 10, and the second connecting blocks 8 are externally rotatably connected to a baffle 11, and one end of the baffle 11 is externally fixedly connected to a connecting plate 12, and the internal thread of the connecting plate 12 is connected to multiple limiting rods 13, and the other end of the baffle 11 is externally rotatably connected to the outside of the second connecting block 8, and one end of the limiting rod 13 passes through the inside of the connecting plate 12 and is arranged inside the second connecting block 8. The outer end of the limiting rod 13 close to the connecting plate 12 is threaded, and the threaded end of the limiting rod 13 passes through the internal thread of the connecting plate 12 and is connected to the inside of the second connecting block 8; the elastic band 10 arranged on the outside of the plurality of second connecting blocks 8 can achieve that when the riser body 1 is clamped, the plurality of clamping blocks 7 can adaptively clamp the riser body 1 through the elasticity of the elastic band 10 itself. After the plurality of clamping blocks 7 clamp the riser body 1, the plurality of second connecting blocks 8 are moved backwards through the elastic contraction of the elastic band 10 itself. When the plurality of second connecting blocks 8 move backwards, the plurality of first connecting blocks 6 are driven to move backwards. When the plurality of first connecting blocks 6 move backwards, the clamping block 7 is driven to move backwards to achieve a more stable clamping effect on the riser body 1. The baffle 11 connected to the outside of the second connecting block 8 can be rotated to limit the elastic band 10, thereby preventing the elastic band 10 from falling off during use.

[0023] Reference Figure 2 , Figure 3The necking part of the riser body 1 is provided with an arc part 3, and the inner wall of the riser body 1 is provided with a wear-resistant coating 2, and the wear-resistant coating 2 is made of polytetrafluoroethylene; the wear-resistant coating 2 made of polytetrafluoroethylene provided inside the riser body 1 can achieve the effect of reducing friction inside the riser body 1. When the friction inside the riser body 1 is reduced, the liquid inside the riser body 1 will flow out more quickly, and the necking part of the riser body 1 is set as the arc part 3, so that when the liquid flows out to the necking part of the riser body 1, the liquid flows out along the arc part 3 provided at the necking part of the riser body 1, so as to achieve the effect of making the viscous liquid flow out quickly.

[0024] Reference Figure 1 A second slot 14 is provided inside the protective device body 4, a first slot 9 is provided inside the second connecting block 8, and the outside of the elastic band 10 is arranged inside the protective device body 4 and the second connecting block 8; the second slot 14 and the first slot 9 provided inside the protective device body 4 and the second connecting block 8 can achieve the effect of limiting the elastic band 10 to prevent the elastic band 10 from deflecting.

[0025] Reference Figure 2 The inner wall of the protective device body 4 and the outer side of the end of the clamping block 7 close to the riser body 1 are both made of rubber material; by making the protective device body 4 and the clamping block 7 both of them into rubber material, when in contact with the riser body 1, the rubber has good shock absorption and vibration reduction capabilities, which can effectively reduce the vibration and noise that may be generated when the liquid flows, and by making the protective device body 4 and the clamping block 7 both of them into rubber material, they can also softly contact with the surface of the riser body 1, effectively reducing the wear and scratches on the surface of the riser body 1.

[0026] Reference Figure 1 The outside of the elastic band 10 is arranged between the second connecting block 8 and the baffle 11; by arranging the outside of the elastic band 10 between the second connecting block 8 and the baffle 11, the elastic band 10 can be limited to prevent the elastic band 10 from falling off during use.

[0027] Working principle: When the device is needed, the elastic band 10 arranged on the outside of the multiple second connecting blocks 8 can achieve the effect of clamping the riser body 1. When the multiple clamping blocks 7 clamp the riser body 1, the elasticity of the elastic band 10 itself causes the multiple clamping blocks 7 to adaptively clamp the riser body 1. After the multiple clamping blocks 7 clamp the riser body 1, the elastic contraction of the elastic band 10 itself causes the multiple second connecting blocks 8 to move backward. When the multiple second connecting blocks 8 move backward, they drive the multiple first connecting blocks 6 to move backward. When the multiple first connecting blocks 6 move backward, they drive the clamping block 7 to move backward to achieve a more stable clamping effect on the riser body 1. When the riser body 1 is clamped by the multiple clamping blocks 7, the protective device main body 4 will protect the outside of the riser body 1 to prevent the riser body 1 from being hit, and the multiple second connecting blocks 8 with elastic bands 10 on the outside drive the first connecting blocks 6 to move. The first connecting block 6 is moved to drive the clamping block 7 to move. When the riser body 1 is impacted and moves inside the protective device body 4, the first connecting block 6 is driven to move by multiple second connecting blocks 8 with elastic bands 10 on the outside, and the clamping block 7 is driven to move by the first connecting block 6, so as to achieve the effect of buffering the impact force on the riser body 1, and the riser body 1 can be fixed by clamping it by multiple clamping blocks 7. The wear-resistant coating 2 made of polytetrafluoroethylene provided inside the riser body 1 can achieve the effect of reducing friction inside the riser body 1. When the friction inside the riser body 1 is reduced, the viscous liquid inside the riser body 1 will flow out more quickly, and the necking part of the riser body 1 is set as the arc part 3, so that when the liquid flows out to the necking part of the riser body 1, the liquid flows out along the arc part 3 provided at the necking part of the riser body 1, so as to achieve the effect of making the viscous liquid flow out quickly.
