Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] Please refer to Figure 1 -Figure 4 The utility model provides an embodiment provided by the utility model discloses a metal pipe float flowmeter,

[0023] A metal pipe float flowmeter, including pipe body 2, the annular groove is set up in the annular side of pipe body 2, the rotary ring 3 is rotatably installed in the annular groove, the lateral fixed mounting of rotary ring 3 has horizontal pole 5, one side of horizontal pole 5 is equipped with instrument indicator 6 through adjusting mechanism, the lateral fixed mounting of pipe body 2 has electromagnetic inductor 7, electromagnetic inductor 7 is connected with instrument indicator 6, the inside of pipe body 2 is equipped with connecting rod 23, the sliding sleeve of guide 19 is equipped on connecting rod 23, guide 19 is fixedly installed on the inner wall of pipe body 2, the bottom end fixed mounting of connecting rod 23 has float 21, the fixed sleeve of permanent magnet block 20 is equipped on connecting rod 23, permanent magnet block 20 is installed in cooperation with electromagnetic inductor 7, the inner wall fixed mounting of pipe body 2 has tapered hole pipe 22, tapered hole pipe 22 is installed in cooperation with float 21, the fixed mounting of rotary ring 3 has fixed mechanism.

[0024] Through the above structure: in use, pipe body 2 can be vertically installed through flange plate 1, when fluid passes, float 21 moves, float 21 drives permanent magnet block 20 to move, the position change information of permanent magnet block 20 can be detected through electromagnetic inductor 7 and is converted into electric signal and is transmitted to instrument indicator 6 to show, during installation, if the installation height of pipe body 2 is higher or lower, at this moment, the staff is inconvenient to observe instrument indicator 6, the position of instrument indicator 6 can be adjusted through adjusting mechanism, so that the staff is convenient to observe instrument indicator 6 later.

[0025] As Figure 1 and Figure 4 The fixed mechanism includes two threaded holes formed in the inner wall of the rotary ring 3, and two bolts 4 are threadedly installed in the two threaded holes. The ends of the two bolts 4 close to each other are in contact with the inner wall of the annular groove. When the orientation of the instrument indicator 6 needs to be adjusted, the two bolts 4 can be loosened, so that the instrument indicator 6 can be rotated. When the instrument indicator 6 is adjusted to the appropriate position, the two bolts 4 can be tightened to fix the position of the instrument indicator 6. At this time, the orientation of the instrument indicator 6 can be adjusted to the direction in which the staff walks conveniently.

[0026] As Figure 3 The adjusting mechanism includes grooves formed in the three side portions of the horizontal pole 5. Two opposite inner walls of the grooves are provided with circular holes 9. Two circular shafts 11 are fixedly installed in the two circular holes 9. The two ends of the circular shafts 11 extend out of the two circular holes 9. Two rotating columns 10 are rotatably sleeved on the circular shafts 11. The ends of the two rotating columns 10 away from the horizontal pole 5 are fixedly installed on the side portions of the instrument indicator 6. Through the arrangement of the rotating columns 10, the instrument indicator 6 can be connected, so that the instrument indicator 6 has a space for rotating up and down.

[0027] As Figure 3As shown, the two rotating pillars 10 have their opposite sides in contact with the two opposing inner walls of the groove. The advantage of this arrangement is that the two rotating pillars 10 can only rotate and cannot move back and forth on the circular shaft 11.

[0028] like Figure 2 and Figure 3 As shown, the adjustment mechanism includes two fixed disks 12. Each of the two fixed disks 12 has multiple uniformly arranged annular fixing holes 13 on its side. The ends of the two fixed disks 12 that are close to each other are fixedly connected to the two ends of the circular shaft 11. Two sliding rods 17 are fixedly installed on the sides of the two rotating columns 10 that are far apart from each other. Moving plates 15 are slidably sleeved on the two sliding rods 17 located on the same side. Arc-shaped plates 8 are fixedly installed on the ends of the two moving plates 15 that are far apart from each other. Mounting blocks 16 are fixedly installed on the sides of the two moving plates 15 that are close to the crossbar 5. The sides of the two mounting blocks 16 that are close to each other are fixedly installed on the sides of the two rotating columns 10 that are far apart from each other by springs 18. Fixing rods 14 are fixedly installed on the sides of the two mounting blocks 16 that are far apart from each other. The two fixing rods 14 extend into two of the fixing holes 13 respectively. Squeezing the two arc-shaped plates 8 will bring the two movable plates 15 closer together, which in turn will bring the two mounting blocks 16 closer together. The two springs 18 will deform, and at the same time, the two mounting blocks 16 will move, causing the two fixing rods 14 to move out of the two fixing holes 13 respectively. At this time, the instrument indicator 6 can be rotated. If the height of the tube body 2 is low, the instrument indicator 6 can be rotated upward; if the height of the tube body 2 is high, the instrument indicator 6 can be rotated downward. When adjusted to the appropriate position, the two arc-shaped plates 8 will be released. Under the action of the two springs 18, the two mounting blocks 16 will move away from each other, so that the two fixing rods 14 can be inserted into the corresponding fixing holes 13, thereby completing the fixation of the instrument indicator 6.

[0029] like Figure 2 As shown, two arc-shaped plates 8 are located on both sides of the instrument indicator 6, with gaps between the sides of the two arc-shaped plates 8 that are close to each other and the annular side of the instrument indicator 6. The advantage of this arrangement is that it allows the two arc-shaped plates 8 to have space to approach each other, thereby allowing the two fixing rods 14 to be moved out of the two fixing holes 13 respectively.

[0030] like Figure 1 As shown, flanges 1 are fixedly installed at both the top and bottom of the pipe body 2. The pipe body 2 can be installed vertically through flanges 1.

[0031] Working principle:

[0032] In use, the pipe body 2 can be installed vertically through the flange 1, when fluid passes through, the float 21 will move, the float 21 drives the permanent magnet block 20 to move, the position change information of the permanent magnet block 20 can be detected through the electromagnetic inductor 7 and converted into an electric signal to be transmitted to the instrument indicator 6 for display;

[0033] During installation, if the height of the pipe body 2 is high or low, it is inconvenient for the staff to observe the instrument indicator 6, the two arc-shaped plates 8 are pinched to make the two moving plates 15 close to each other, so that the two mounting blocks 16 are close to each other, the two springs 18 are deformed, and the two mounting blocks 16 move to drive the two fixed rods 14 to move out of the two fixed holes 13, at this time the instrument indicator 6 can be rotated, if the height of the pipe body 2 is low, the instrument indicator 6 is rotated upward, if the height of the pipe body 2 is high, the instrument indicator 6 can be rotated downward, when adjusted to the appropriate position, the two arc-shaped plates 8 are loosened, the two mounting blocks 16 are away from each other under the action of the two springs 18, so that the two fixed rods 14 are inserted into the corresponding fixed holes 13, so that the position of the instrument indicator 6 is fixed;

[0034] When the orientation of the instrument indicator 6 needs to be adjusted, the two bolts 4 can be loosened, so that the instrument indicator 6 can be rotated, when adjusted to the appropriate position, the two bolts 4 are tightened to fix the position of the instrument indicator 6, at this time the instrument indicator 6 can be oriented in the direction convenient for the staff to walk.

[0035] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
