Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 2 As shown, a tank diameter detection device includes a base 1 and a measuring mechanism. Two support rods 101 are provided at the upper end of the base 1, and a height-adjustable guide rod 102 is connected between the two support rods 101. The measuring mechanism includes a crossbeam 2, which is slidably engaged with the guide rod 102. A first measuring roller 5 and a second measuring roller 6 are provided on one side of the crossbeam 2, parallel to each other. The first measuring roller 5 is fixedly connected to the crossbeam 2 via a first roller frame 501, and the second measuring roller 6 is slidably engaged with the crossbeam 2 via a second roller frame 601. A scale 4 is provided on the other side of the crossbeam 2, and a pointer 603, cooperating with the scale 4, is connected to the second roller frame 601. The 0 mark of the scale 4 is flush with the first measuring roller 5 (the side in contact with the tank), and the pointer 603 is flush with the second measuring roller 6 (the side in contact with the tank). The reading of the pointer 603 is the distance between the first measuring roller 5 and the second measuring roller 6, which is also the diameter of the tank.

[0025] A handle 202 is installed on the crossbeam 2 or the guide rod 102. The measuring mechanism can be moved up and down through the handle 202 to measure the tank from bottom to top or from top to bottom. If the handle 202 is on the crossbeam 2, the crossbeam 2 can be moved by holding the handle 202 upwards with your hand to ensure that the crossbeam 2 can move with the change of the tank diameter. If the handle 202 is installed on the guide rod 102, the handle 202 can be held directly for movement.

[0026] The lower end of the crossbeam 2 is provided with a support block 201 that slides with the guide rod 102. The support block 201 is sleeved on the outside of the guide rod 102. Since the crossbeam 2 and the guide rod 102 are in sliding fit, the measuring mechanism can adjust its position according to the change of the diameter of the tank to ensure the accuracy of the measurement.

[0027] The guide rod 102 is connected to sleeves 104 that slide with the support rod 101 at both ends. The sleeves 104 are equipped with locking bolts 103, which can be used to position the height of the measuring mechanism.

[0028] like Figure 3 As shown, a guide rail 3 is provided on the side wall of the crossbeam 2. The end of the second roller frame 601 is engaged with the guide rail 3 through a slider 602. A push rod 605 is connected to the side wall of the second roller frame 601. A spring 604 and a push block 7 are sleeved on the push rod 605. The push block 7 is sleeved on the outside of the push rod 605. The push block 7 and the push rod 605 are in sliding engagement. The push block 7 is connected to the guide rail 3 through a positioning bolt. The spring 604 is located between the second roller frame 601 and the push block 7.

[0029] The guide rail 3 is evenly provided with positioning holes 301 that cooperate with the positioning bolts.

[0030] like Figure 4 As shown, a push ring 701 for a push spring 604 is provided on one side of the push block 7, and a fixing plate 702 is provided on the side wall of the push block 7. The fixing plate 702 is connected to the guide rail 3 by a positioning bolt.

[0031] After the first measuring roller 5 and the second measuring roller 6 clamp the tank, the sliding push block 7 and the push ring 701 compress the spring 604, so that the spring 604 gives the second measuring roller 6 a certain pushing force, ensuring that the second measuring roller 6 can press against the side wall of the tank. Then, the push block 7 is fixed by the positioning bolt. Since the push rod 605 and the push block 7 slide together, the second measuring roller 6 can move with the change of the diameter of the tank, so as to realize the diameter measurement of the tank at different heights.

[0032] like Figure 5 As shown, during use, the first measuring roller 5 and the second measuring roller 6 clamp the tank and fix the push block 7. Then, the handle 202 is slowly moved from bottom to top or from top to bottom. The pointer 603 is observed to see if there is any change. The measurement data is recorded (only the data that changes is recorded), thereby realizing the overall measurement of the tank diameter. Alternatively, several points can be selected for measurement and recording, and the average value can be taken as the tank diameter.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
