The length of the filter cartridge to be tested is generally 1 to 3 meters. The height of the general test device must be greater than 3 meters, and the height of the test space must also reach more than 6 meters. The test space requirements are extremely high, and some test institutions are difficult to meet the requirements;

[0004] ② During the test, the level of the flower board is adjusted through the foot cup at the bottom of the rack. The flower board and the foot cup are respectively set at the two ends of the rack. During the adjustment, a single person cannot obtain the level of the flower board in real time. At least two people are required to complete the adjustment (one adjustment and one look), and the adjustment operation is relatively complicated;

[0036] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0037] refer to Figures 1 to 5 As shown, the utility model discloses a filter cartridge vertical deviation testing device, comprising a frame 1, a guide rail 2, a flower plate 3, an adjusting screw 4, a level 5 and a photoelectric sensor 6;

[0038] A pair of guide rails 2 arranged in a horizontal direction are provided on the top of the frame 1;

[0039] The lower surface of the flower plate 3 is slidably fitted on the guide rail 2, and a sealing ring 31 for mounting the filter cartridge a is provided thereon;

[0040] The adjusting screw 4 is threadedly connected to the upper surface of the flower plate 3 and penetrates the flower plate 3 to abut the upper surface of the guide rail 2. The two ends of the guide rail 2 are correspondingly provided with adjusting screws 4 (based on the state of the flower plate 3 sliding into the frame 1);

[0041] Two mutually perpendicular spirit levels 5 are provided on the upper surface of the flower plate 3. The spirit levels 5 cooperate with the adjusting screw 4 to adjust the horizontality of the flower plate 3 and observe the adjustment effect in real time.

[0042] A plurality of photoelectric sensors 6 are arranged on the upper surface of the flower plate 3 , and the photoelectric sensors 6 are arranged circumferentially around the sealing ring 31 . The flower plate 3 is provided with through holes 32 for giving way to the photoelectric sensors 6 , and the through holes 32 penetrate the upper and lower surfaces of the flower plate 3 .

[0043] Specific embodiments of the present utility model are shown below.

[0044] The frame 1 includes two end frames 11 and four vertical rods 12; the end frame 11 includes a crossbar and two vertical rods, and the two vertical rods are respectively connected to the two ends of the crossbar vertically, so that the end frame 11 leaves an opening for the filter cartridge a to enter and exit; the four corners of the two end frames 11 are vertically connected with the vertical rods 12. Corresponding to the relevant structure of the frame 1, the guide rail 2 is arranged along the longitudinal direction.

[0045] Furthermore, an adjustable foot cup 13 is respectively installed on the lower surface of the four corners of the lower end frame 11 of the above-mentioned rack 1, which can roughly adjust the verticality of the entire rack 1 so that the rack 1 can maintain a roughly vertical state before testing.

[0046] The inner wall at the top of the frame 1 is provided with a plurality of fixing brackets 14 , and the guide rails 2 are mounted on the fixing brackets 14 .

[0047] The lower surface of the flower plate 3 is provided with a slide groove 7 which is slidably sleeved on the guide rail 2. Adjustment screws 4 are provided at both ends of each slide groove 7. The adjustment screws 4 penetrate into the slide groove 7 so that when the adjustment screws 4 are turned, the lower end of the adjustment screws 4 can resist the upper surface of the guide rail 2 in the slide groove 7, thereby adjusting the horizontality of the flower plate 3.

[0048] Furthermore, the cross-section of the guide rail 2 is an inverted isosceles trapezoid, and the cross-section of the slide groove 7 includes a flat plate 71 located on the upper surface of the guide rail 2, and inclined side plates 72 located on both sides of the guide rail 2. The inclined side plates 72 are inclined in the same direction as the waist of the isosceles trapezoid, and when the adjusting screw 4 is turned, the lower end of the inclined side plate 72 can movably abut the side of the guide rail 2, thereby playing a role of vertical limiting.

[0049] The center of the sealing ring 31 overlaps with the center of the flower plate 3 to ensure that after the filter cartridge a is installed, the center of gravity of the flower plate 3 and the filter cartridge a as a whole is on the central vertical line of the flower plate 3 to ensure that the force on the flower plate 3 is balanced.

[0050] The above-mentioned level gauges 5 are respectively arranged along the horizontal direction and the vertical direction of the flower plate 3, and are all arranged at the center of the corresponding edges.

[0051] The photoelectric sensors 6 are arranged at equal angles around the circumference of the sealing ring 31 .

[0052] The above-mentioned photoelectric sensor 6 is installed on the upper surface of the flower plate 3 through the right-angle sheet metal 8. The locking position of the right-angle sheet metal 8 on the flower plate 3 is adjustable, so that the position of the photoelectric sensor 6 can be adjusted within a certain range to match filter cartridges a of different diameters. The general adaptation range is 130 to 160 mm.

[0053] The workflow of the utility model is:

[0054] Hang the filter cartridge a on the sealing ring 31 of the flower plate 3, and push it into the frame 1 along the guide rail 2; observe the conditions of the two spirit levels 5 to determine whether the flower plate 3 is horizontal, if not, adjust it by turning the adjusting bolts; after completing the horizontal adjustment of the flower plate 3, start the photoelectric sensor 6, observe the signal light, and obtain the range data of the verticality of the filter cartridge a.

[0055] Through the above scheme, the flower plate 3 of the utility model is slidably matched with the top of the frame 1 through the guide rail 2, and a side-entry assembly method is adopted, which greatly reduces the demand for test space; the spirit level 5 installed on the flower plate 3 can observe the horizontal condition of the flower plate 3 in real time when the adjusting bolt is turned, thereby improving the convenience of adjusting the horizontal degree of the flower plate 3; a photoelectric sensor 6 is arranged at the position corresponding to the through hole 32 of the flower plate 3, and the verticality of the filter cartridge a is directly tested in an electronic way, thereby shortening the test waiting time, improving the test efficiency, avoiding the test errors caused by manual work, and improving the test accuracy.

[0056] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
