[0036] Figure 1 The general assembly schematic diagram of the bellmouth adapter device 1000 according to an embodiment of the present application is shown.

[0037] As Figure 1 shown, since the components of the bellmouth structure have a relatively thin wall surface at the bellmouth and extend obliquely, if an assembly tool with a strong clamping force is used for connection, it may cause damage to the bellmouth part itself. If a device tool with a small clamping force is used for connection, then as the usage time increases, the assembly tool may slip on the obliquely extending wall surface and cannot achieve a stable and smooth connection.

[0038] To solve the problem that it is difficult to stably install and fix other components on the components with a flared structure, an embodiment of the present invention provides a flared adapter device 1000 for connecting a flared part 300, including an adapter component 100 and a calibration component 200. Among them, the adapter component 100 is used to connect the flared part 300 and other external components, playing a bridging role when connecting the two; the calibration component 200 is installed on the adapter component 100 and used together to determine whether the adapter component 100 is in a leveled state. If it is not in a leveled state, it guides the adapter component 100 to be further leveled, so that the adapter component 100 can be stably installed on the flared part 300, facilitating the subsequent installation of other external components on the adapter component 100, and further enabling the stable connection between the flared part 300 and other external components through the adapter component 100, solving the problem that it is difficult for the flared part 300 to stably connect other external components due to its thin wall.

[0039] Please refer to Figure 1 , the adapter component 100 in the flared adapter device 1000 includes a fixing frame 11, an abutting member 12, a leveling component 13 and a positioning block 16. The flared part 300 has a flared portion 31 and a lug 33 connected to the flared portion 31. Among them, the fixing frame 11 is placed on the flared portion 31. There are at least four abutting members 12, which are arranged in pairs on opposite sides of the fixing frame 11 along the first direction F1, and are rotatably connected to the fixing frame 11 around an axis parallel to the second direction F2. When the abutting member 12 rotates towards the side close to the fixing frame 11, the abutting member 12 can abut against the flared part 300 along the first direction F1, thereby restricting the degrees of freedom of the fixing frame 11 in the first direction F1 and the third direction F3. The positioning block 16 is located on opposite sides of the lug 33 along the second direction F2, and two positioning bolts 17 are provided on the positioning block 16 and penetrate through the positioning block 16 along the second direction F2 and abut against both sides of the lug 33, for restricting the degree of freedom of the flared adapter device 1000 in the second direction F2. The leveling component 13 includes at least four leveling members 131 symmetrically arranged along the lug axis L1. The leveling members 131 are connected between the fixing frame 11 and the flared portion 31, and are configured to move along the third direction F3 to adjust the levelness of the fixing frame 11 relative to the plane where the flared portion 31 is located. Among them, the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other in pairs. In this way, when the fixing frame 11 has a certain inclination angle relative to the horizontal plane, the heights of multiple leveling members 131 can be adjusted one by one respectively, so that the inclination angle of the fixing frame 11 is gradually corrected and reaches a horizontal state, and the flared adapter device 1000 is firmly connected to the flared part 300 through the abutting member 12 and the positioning bolts 17.

[0040] Figure 2 Shows a schematic structural diagram of the adapter component according to an embodiment of the present application.

[0041] Combined Figure 2 As shown, in some embodiments, the abutting member 12 includes a buckle 121 rotatably connected to the fixing bracket 11 about an axis parallel to the second direction F2, and an abutting portion 122 movably inserted through the fixing bracket 11 along the third direction F3. Among them, a boss 123 is provided on both sides of the buckle 121 along the second direction F2, and one end of the abutting portion 122 abuts against the boss 123 along the third direction F3. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other in pairs. In this way, when it is necessary to fix the fixing bracket 11 on the bell mouth portion 31, the abutting portion 122 can be moved downward along the third direction F3 so that it abuts against the boss 123 and drives the buckle 121 to rotate toward one side of the bell mouth portion 31 about an axis parallel to the second direction F2. The buckle 121 can then abut against the bell mouth portion 31, thereby preliminarily fixing the fixing bracket 11 on the bell mouth portion 31. Conversely, when it is necessary to release the connection between the fixing bracket 11 and the bell mouth portion 31, only need to move the abutting portion 122 in the opposite direction so that it gradually moves away from the boss 123. In this way, the buckle 121 loses the restriction of the abutting portion 12 and can rotate toward the side away from the bell mouth portion 31, so that the fixing bracket 11 and the bell mouth portion 31 are disengaged.

[0042] Optionally, the abutting portion 122 includes a first threaded section extending along the third direction F3, and a first threaded hole adapted to the first threaded section is provided on the fixing bracket 11. In this way, through the threaded connection between the abutting portion 122 and the fixing bracket 11, the abutting portion 122 can move freely along the third direction F3, ensuring that the abutting portion 122 provides a stable supporting force for the boss 123, so that the buckle 121 can stably abut against the bell mouth portion 31, thereby realizing the preliminary connection between the fixing bracket 11 and the bell mouth portion 31. In addition, the bell mouth adapter device 1000 further includes four guiding blocks 14 provided on opposite sides of the fixing bracket 11 along the first direction F1. The guiding blocks 14 extend toward the bell mouth part 300 along the third direction F3. In this way, when the bell mouth adapter device 1000 is installed, it can be guided and positioned along the guiding blocks 14 and the positioning blocks 16 respectively.

[0043] Furthermore, one end of each leveling member 131 abuts against the bell mouth portion 31 and can rotate relative to the bell mouth portion 31. The other end is provided with a second threaded section extending along the third direction F3. The fixing bracket 11 is provided with second threaded holes corresponding to the leveling members 131 one by one and adapted to the second threaded sections. In this way, the leveling height can be controlled by rotating the leveling member 131 so that it moves along the third direction F3 in the second threaded hole of the fixing bracket 11, and the adjustment of small displacements can be achieved by means of threaded connection. For example, when a certain position of the fixing bracket 11 is lower and the fixing bracket 11 has a small inclination angle relative to the horizontal plane, the leveling member 131 near this lower position can be slightly rotated to gradually increase the height until it is flush with other positions. At this time, the fixing bracket 11 is corrected to a horizontal state.

[0044] Figure 3 FIG. shows a schematic structural diagram of a calibration assembly according to an embodiment of the present application.

[0045] Please refer to Figure 1 and Figure 3 In one embodiment, at least two guide pins 15 are provided on opposite sides of the fixing bracket 11 along the first direction F1 and / or the second direction F2. The guide pins 15 extend along the third direction F3 away from the bell mouth part 300. The bell mouth adapter device 1000 further includes a calibration assembly 200. The calibration assembly 200 includes a horizontal calibration member 21. The horizontal calibration member 21 is provided with calibration holes 213 corresponding to the guide pins 15 one by one. It can be understood that the guide pins here can be used to connect the calibration assembly 200 during calibration and can also be used to connect other external parts of the installation after calibration. In addition, during the aforementioned leveling process, since there is no horizontal reference object, the fixing bracket 11 can only be roughly in a horizontal state. In order to better judge the levelness of the fixing bracket 11 relative to the bell mouth and further adjust and improve its levelness, the present application combines the horizontal calibration member 21 and the centering calibration member 22 to jointly guide the leveling action of the leveling member 131.

[0046] During actual use, first install the horizontal calibration piece 22 on the fixing frame 11 through the guide pin 15, so that the corresponding positions of the fixing frame 11 and the horizontal calibration piece 21 can be in full contact. Then, as a whole, the adaptation component 100 and the calibration component 200 are initially lapped on the bellmouth part 300 under the positioning and guiding of the guide block 14 and the positioning block 16, so that the alignment calibration piece 22 can smoothly enter the straight tube part 32 of the bellmouth. At this time, by rotating the leveling pieces 131 one by one, the four leveling pieces 131 are all in full contact with the plane where the bellmouth part 31 is located, indicating that the fixing frame 11 has also reached a horizontal state relative to the bellmouth part 31. Then tighten the abutting part 122 of the abutting piece 12, drive the buckle 121 to rotate towards the bellmouth part 31 around the axis parallel to the second direction F2, and initially fix the fixing frame 11 on the bellmouth part 31. Finally, tighten the positioning bolt 17 on the positioning block 16 so that the positioning bolt 17 abuts against the lug 33 to achieve complete fixation. In this way, the bellmouth adaptation device 1000 can be horizontally and stably connected to the bellmouth part 300.

[0047] Specifically, the horizontal calibration member 21 includes a first horizontal calibration plate 211 extending along the first direction F1, and a second horizontal calibration plate 212 perpendicular to the first horizontal calibration plate 211 and extending along the second direction F2. Two calibration holes 213 are respectively provided at opposite ends of the first horizontal calibration plate 211 along the longitudinal direction of the first horizontal calibration plate 211. The flared part 300 has a straight tube part 32 connected to the flared part 31 and extending along the third direction F3. The calibration assembly 200 includes a connecting member 24 connected to one side of the horizontal calibration member 21 facing the flared part 31 along the third direction F3. There is a preset interval between the connecting member 24 and the straight tube part 32 in both the first direction F1 and the second direction F2. It can be understood that when the guide pin 15 is inserted into the corresponding calibration hole 213, the first horizontal calibration plate 211 and the second horizontal calibration plate 212 abut against the fixing frame 11 along the third direction F3. The adapter assembly 100 and the calibration assembly 200 will be assembled with the flared part 300 as a whole. During this process, the connecting member 24 continuously penetrates into the straight tube part 32. If the adapter assembly 100 and the calibration assembly 200 are exactly horizontal relative to the fixing frame 11, the connecting member 24 can completely enter the straight tube part 32, and each leveling member 131 can also be in full contact with the plane where the flared part 31 is located. If the adapter assembly 100 and the calibration assembly 200 have a certain inclination angle relative to the fixing frame 11, the connecting member 24 will be stuck when it reaches a certain depth in the straight tube part 32, and the greater the inclination angle, the shorter the length that can penetrate. At this time, only some leveling members 131 can be in contact with the plane where the flared part 31 is located. Therefore, the inclination angle of the flared part adapter device 1000 can be gradually reduced by rotating each leveling member 131 one by one until each leveling member 131 can be in full contact with the plane where the flared part 31 is located, that is, the flared part adapter device 1000 is in a horizontal state relative to the fixing frame 11.

[0048] In order to make the central axis of other parts to be installed later consistent with the central axis of the bell-mouth part 300, so as to better and stably install other parts on the bell-mouth part 300, the calibration assembly 200 in the present application also includes a centering calibration member 22 provided on the connecting member 24 and adapted to the straight tube part 32, so that when the guide pin 15 is inserted into the corresponding calibration hole 213, it can be adaptively embedded in the straight tube part 32. In other words, when the centering calibration member 22 can extend into the straight tube part 32 of the bell-mouth part 300, it means that the central axis of the bell-mouth adapter 1000 at this time is consistent with the central axis of the bell-mouth part 300, then other parts can also be installed on the bell-mouth adapter 1000 under the guiding effect of the guide pin 15. Keep consistent with the central axis of the bell-mouth part 300, so as to facilitate other operations in cooperation with the bell-mouth part 300. On the contrary, if the centering calibration piece 22 cannot be inserted into the straight tube part 32 of the bell-mouth part 300, it means that the central axis of the bell-mouth adapter 1000 is misaligned with the bell-mouth part 300, and it is necessary to readjust the position of the fixing frame 11 relative to the bell-mouth part 300 in the first direction F1 or the second direction F2 until the centering calibration piece 22 can be installed in the straight tube part 32 of the bell-mouth part 300, and the central axes of the two coincide. At this time, the adapter assembly 100 is firmly and horizontally connected to the bell-mouth part 300, and the calibration assembly 200 can be removed from the guide pin 15, and other parts that need to be assembled with the bell-mouth part 300 are connected to the guide pin 15, thereby solving the problem of difficulty in stably installing other parts due to the thin wall surface of the bell-mouth part 300.

[0049] It should be noted that when the centering calibration piece 22 cannot be installed on the straight tube portion 32 of the bell-mouth part 300, it may also be that the centering of the bell-mouth adapter device 1000 is good, but the levelness is not good. Therefore, the centering calibration piece 22 in the present application can also play an auxiliary role in the calibration of the levelness.

[0050] Optionally, the centering calibration piece 22 can be formed by connecting four calibration strips 221 whose outer diameters match the inner diameters of the straight tube portion 32. The second horizontal calibration plate 212 can be arranged at the side of the first horizontal calibration plate 211, so that the calibration of the centering calibration piece 22 in the straight tube portion 32 can be observed more conveniently.

[0051] Furthermore, the calibration component 200 also includes a handle 23 disposed on the side of the horizontal calibration member 21 away from the fixing frame 11, so as to facilitate the user to use it during the installation process.

[0052] In summary, the bell mouth adapter device 1000 according to some specific embodiments of the present invention has the following three advantages:

[0053] a. It is convenient to operate and has a stable connection. When the present invention is used, first rotate the abutting portion 122 on the fixing frame 11 to loosen the buckle 121. After placing the bell mouth adapter device 1000, the levelling component 13 can be used to adjust the levelness of the bell mouth adapter device 1000. Then, tighten the abutting portion 122 to drive the buckle 121 to rotate, and the device can be stably connected to the bell mouth portion 31.

[0054] b. It has a high levelness and good centering. When the present invention performs the levelling operation, the horizontal calibration piece 21 is used to guide the levelling action of the levelling piece 131. And while the centering calibration piece 22 checks whether the installation is centered, it can also play an auxiliary role in checking whether it is horizontal.

[0055] c. The adjustment accuracy is relatively high. A plurality of levelling pieces 131 symmetrically arranged along the axis L1 of the lifting lug are threadedly connected to the fixing frame 11. When the inclination angle of the fixing frame 11 is small, small displacement adjustment can also be achieved by slightly rotating the levelling piece 131.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
