Description

Technical Field

[0004] The existing method for testing the barrel-like structure of the mixer 21 is to lock and fix the sealing plate 22 to the port 21a of the mixer 21 with multiple bolts, and then fill the gas through the test tube 23 on the sealing plate 22. The airtightness of the mixer 21 can be determined by whether the pressure of the test gas changes within a certain period of time.

[0005] However, the existing method of tightening the sealing plate 22 with bolts requires a significant amount of time to secure the bolts, as... Figure 1 The mixer 21 in the example has twelve locking holes on its port 21a, so twelve bolts are needed for locking. For different models of mixer 21, even more bolts are needed to lock and fix the sealing plate 22. The existing test structure is too cumbersome in actual testing. In order to solve the above shortcomings, the mixer air tightness testing device of this application is proposed. Utility Model Content

[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] like Figures 1 to 4 As shown, a mixer airtightness testing device 10 is used to test the airtightness of a mixer 21. It includes a base plate 100 and a sealing assembly 200. The sealing assembly 200 includes a sealing cover 210, a top rod 220, a plurality of guide rods 230 and a plurality of fasteners 240. Each guide rod 230 passes through the base plate 100 and one end of each guide rod 230 is connected to the sealing cover 210. The top rod 220 is screwed to the base plate 100 and one end of the top rod 220 abuts against the sealing cover 210. Each fastener 240 is rotatably disposed at the edge of the base plate 100. When the fastener 240 is subjected to force and rotates to engage with the base plate 100 and the mixer 21 respectively, and when the top rod 220 is subjected to force and rotates, the top rod 220 pushes the sealing cover 210 to make it tightly connected with the port 21a of the mixer 21.

[0035] It should be noted that one end of each guide rod 230 is fixedly installed on the sealing cover 210, and the guide rods 230 are spaced apart from each other, and each guide rod 230 penetrates the base plate 100. In this way, the surface of the sealing cover 210 is parallel to the surface of the base plate 100, and the sealing cover 210 can be close to or away from the base plate 100 through the guide rods 230. The top rod 220 is screwed to the middle part of the base plate 100, and the end of the top rod 220 abuts against the middle part of the sealing cover 210. In this way, when the top rod 220 is forced to rotate, the top rod 220 can push the sealing cover 210 away from the base plate 100, or the top rod 220 is away from the sealing cover 210, so that the sealing cover 210 slides to close to the base plate through the guide rods 230. Each buckle member 240 is rotatably installed at the edge position of the base plate 100, and when the buckle member 240 is forced to rotate, the buckle member 240 can be buckled to the base plate 100 and the blender 21 respectively, or the buckle member 240 is separated from the blender 21. In this way, when the sealing cover 210 abuts against the port 21a of the blender 21, then the buckle member 240 is rotated towards the center of the base plate 100, and then the top rod 220 is twisted to rotate, so that the top rod 220 pushes the sealing cover 210 away from the base plate 100, when the buckle member 240 is buckled to the base plate 100 and the blender 21 respectively, it means that the distance between the base plate 100 and the blender 21 cannot be increased again, and as the top rod 220 continues to rotate to push the sealing cover 210 away from the base plate 100, so that the sealing cover 210 is pushed by the top rod 220 to tightly abut against the port 21a of the blender 21, so that the sealing cover 210 seals the blender 21, and then the blender 21 can be filled with air for air tightness test through the pipeline on the sealing cover 210. In this way, compared with the existing air tightness test structure using bolt locking and fixing, the blender air tightness test device 10 of the present application can directly drive the top rod 220 to rotate through the electric drill, so as to quickly and reliably seal the blender 21 by the sealing cover 210, and is convenient to use.

[0036] As shown in Figure 1 , in an embodiment, the base plate 100 is provided with a hollow hole 110, so that the air pipe 211 of the sealing cover 210 penetrates out of the hollow hole 110.

[0037] It should be noted that the air pipe 211 is provided with two, one of the two air pipes 211 is used for communicating with the external air supply pump, and the other is used for installing the air pressure gauge, so that the air tightness of the blender 21 can be detected in real time.

[0038] As shown in Figure 1 , in an embodiment, the end of the top rod 220 away from the sealing cover 210 is provided with a hexahedron 221. In this way, it is convenient to apply torque to the top rod 220, so that the top rod 220 can be reliably twisted.

[0039] AsFigure 1 As shown in the figure, in an embodiment, two handles 250 are arranged on the side of the substrate 100 away from the sealing cover 210, and a space is arranged between the two handles 250. In this way, the two handles 250 facilitate the workers to carry the detection device.

[0040] As shown in the figure, in an embodiment, a plurality of side ears 120 are arranged on the outer peripheral wall of the substrate 100 at equal intervals, and each buckle member 240 is arranged through the side ear 120 one by one. Figure 1

[0041] It should be noted that the outer diameter of the substrate 100 is consistent with the outer diameter of the sealing cover 210, and in order to enable the buckle member 240 to reliably buckle the substrate 100 and the blender 21, the side ear 120 is arranged on the outer peripheral wall of the substrate 100. Each side ear 120 is arranged on the outer peripheral wall of the substrate 100 at a circumferential equal angle.

[0042] As shown in the figure, in an embodiment, the buckle member 240 includes a slide column 241, two horizontal blocks 242, and two pad blocks 243. The slide column 241 is arranged through the side ear 120, the two horizontal blocks 242 are arranged on the two ends of the slide column 241 respectively, and the two horizontal blocks 242 extend in the same direction of the slide column 241. The two pad blocks 243 are arranged on the side of the two horizontal blocks 242 that are close to each other. When the buckle member 240 is forced to rotate, one of the two pad blocks 243 buckles the substrate 100, and the other buckles the blender 21. Figure 4 It should be noted that the slide column 241 passes through the side ear 120, the two horizontal blocks 242 are arranged on the two ends of the slide column 241 respectively, and the horizontal blocks 242 extend in the same direction of the slide column 241. The two pad blocks 243 are arranged on the two opposite sides of the horizontal blocks 242. In this way, when the buckle member 240 is forced to rotate relative to the side ear 120, the horizontal blocks 242 are directed to the center position of the substrate 100, and the two pad blocks 243 can buckle the substrate 100 and the blender 21.

[0043] As shown in the figure, in an embodiment, the sealing assembly 200 further includes a plurality of clamping members 260. Each clamping member 260 is arranged through the side ear 120, and each clamping member 260 is used to clamp each slide column 241.

[0044] Figure 4 It should be noted that the clamping member 260 passes through the side ear 120 transversely, and the clamping member 260 is used to clamp the slide column 241. In this way, the clamping member 260 can be rotated by an external force, and the clamping member 260 can be rotated relative to the side ear 120, and the detection device can not be randomly swung during the carrying process. Therefore, when the blender 21 is subjected to the air tightness detection, it can be ensured that the pad block 243 reliably directs to the side away from the center of the substrate 100.

[0045] It should be noted that the clamping member 260 passes through the side ear 120 transversely, and the clamping member 260 is used to clamp the slide column 241. In this way, the clamping member 260 can be rotated by an external force, and the clamping member 260 can be rotated relative to the side ear 120, and the detection device can not be randomly swung during the carrying process. Therefore, when the blender 21 is subjected to the air tightness detection, it can be ensured that the pad block 243 reliably directs to the side away from the center of the substrate 100. ​​

[0046] As Figure 4 shown, in an embodiment, the outer side wall of the slide post 241 on the opposite side is provided with a flat surface 2411, and when the slide post 241 is forced to rotate, the flat surface 2411 abuts or moves away from the clamping member 260.

[0047] It should be noted that, in an embodiment, the clamping member 260 is a ball head plunger, which is transversely screwed into the side lug 120, so that the movable end of the ball head plunger abuts the slide post 241. In this way, when the slide post 241 is forced to rotate, the flat surface 2411 abuts the ball head plunger, and since the slide post 241 needs to overcome the elastic force of the spring inside the ball head plunger to rotate away from the flat surface 2411, the cross block 242 can be kept either towards the center of the base plate 100 or away from the center of the base plate 100, so that the clamping member 240 can be kept in a state of clamping the base plate 100 to the blender 21 or away from the blender 21, so that the blender air tightness detection device 10 of the present application is convenient to use, and in particular, when the blender air tightness detection device 10 is clamped to the blender 21, each clamping member 240 will not swing randomly.

[0048] In an embodiment, four guide rods 230 are provided, which are distributed at equal angles around the center of the sealing cover 210. In this way, the sealing cover 210 can stably slide towards or away from the base plate 100.

[0049] As Figure 1 shown, in an embodiment, the end of the guide rod 230 away from the sealing cover 210 is provided with a limiting head 270, and the diameter of the limiting head 270 is greater than the diameter of the guide rod 230.

[0050] It should be noted that the diameter of the limiting head 270 is greater than the diameter of the guide rod 230, so that the guide rod 230 can be prevented from being pulled out of the base plate 100. Further, in order to enable the guide rod 230 to stably slide relative to the base plate 100, a linear bearing is installed on the base plate 100, and the guide rod 230 passes through the linear bearing.

[0051] In an embodiment, a sealing ring is arranged in the port 21a of the blender 21, so that the sealing cover 210 can reliably seal the sealing ring.

[0052] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. Among them, the installation / fixed / setting in the utility model is understood as including but not limited to the locking and fixing by using screw / screw, welding unless otherwise defined. It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
