DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-6 As shown, a dust filter detection device for an engine filter comprises a workbench 1, and a plurality of bottom fixing brackets 11 are fixedly connected to the bottom of the workbench 1.

[0029] The top of the workbench 1 is rotatably connected to a tooling disc 2 , and the top of the tooling disc 2 is fixedly connected to a concave tooling frame 21 .

[0030] The bottom of the tooling disc 2 is fixedly connected with a motor 3 , the interior of the motor 3 is rotatably connected with a threaded rod 31 , and the threaded rod 31 is rotatably connected to the interior of the tooling disc 2 .

[0031] One end of the threaded rod 31 disposed in the concave fixture frame 21 is threadedly connected to a straight plate 32 , both ends of the straight plate 32 are provided with empty grooves 33 , and a connecting round rod 34 is fixedly connected inside the empty groove 33 .

[0032] A connecting plate 4 is arranged above the workbench 1 , and one end of the connecting plate 4 away from the inner cylinder 6 is rotatably connected to the outer side of the connecting round rod 34 .

[0033] An inner chamber 41 is formed inside the connecting plate 4 , a square groove 42 is formed on the top of the connecting plate 4 , an inner cylinder 6 is fixedly connected to the side wall of the connecting plate 4 , and an engine filter body 7 is sleeved on the outer side of the inner cylinder 6 .

[0034] A driving gear 341 is engraved on one end of the connecting round rod 34 arranged in the inner chamber 41, and a driven gear 5 is rotatably connected inside the inner chamber 41. The driven gear 5 and the driving gear 341 are meshed with each other. A guide wheel 52 is fixedly connected to the top of the driven gear 5. A torsion spring 51 is arranged inside the inner chamber 41, and both ends of the torsion spring 51 are respectively fixedly connected to the guide wheel 52 and the connecting plate 4, and the end of the elastic connecting rope 53 away from the inner cylinder 6 is fixedly connected to the guide wheel 52.

[0035] When testing, it is necessary to fix the engine filter body 7 on the device. The initial position of the connecting plate 4 is vertical. At this time, the resistance block 63 is inside the inner cylinder 6, and the engine filter body 7 can be smoothly sleeved on the outside of the inner cylinder 6. When testing, the connecting plate 4 starts to rotate until it is horizontal with the workbench 1. Through the meshing effect of the driven gear 5 and the driving gear 341, the driven gear 5 itself rotates, and the elastic connecting rope 53 is wound around the guide wheel 52, so that the elastic connecting rope 53 can pull the conical slider 62 to move in the direction close to the connecting plate 4. Through the contact between the conical slider 62 and the resistance block 63, the conical slider 62 can squeeze the resistance block 63 out to make it resist the inner wall of the engine filter body 7, thereby achieving a preliminary fixing effect on the engine filter body 7. This fixing operation can be achieved without the need for staff operation. The operation is simple and convenient, reduces the steps of detection, and reduces the risk of staff errors.

[0036] A guide slide bar 61 is provided inside the inner cylinder 6, and the guide slide bar 61 is fixedly connected to the side wall of the connecting plate 4. A conical slider 62 is slidably connected to the outer side of the guide slide bar 61, and an elastic connecting rope 53 is fixedly connected to the side wall of the conical slider 62. A resistance block 63 is slidably connected to the side wall of the inner cylinder 6, wherein the guide slide bar 61 and the resistance block 63 can be connected by an elastic rope or a spring to ensure that the resistance block 63 can be retracted into the inner cylinder 6 when the resistance block 63 is not in contact with the conical slider 62, so as to avoid the problem that when the engine filter body 7 is sleeved on the outer side of the inner cylinder 6, the protrusion of the resistance block 63 will affect the normal insertion of the engine filter body 7, causing damage to the engine filter body 7, thereby affecting the final detection data.

[0037] One end of the elastic connecting rope 53 away from the conical slider 62 extends into the square groove 42, and a driving blade 67 is arranged inside the square groove 42. The bottom of the driving blade 67 is fixedly connected to a rotating rod 66, and the bottom of the rotating rod 66 is fixedly connected to a ring 68. One end of the elastic connecting rope 53 away from the conical slider 62 is sleeved on the outside of the ring 68, and one end of the conical slider 62 away from the connecting plate 4 is fixedly connected to a restoring spring 64.

[0038] When testing the engine filter body 7, the wind will pass through the square slot 42 and drive the driving blade 67 to rotate. Due to the rotation of the driving blade 67, the elastic connecting rope 53 will be wrapped around the ring 68, so that the elastic connecting rope 53 will pull the tapered slider 62 again to move it toward the connecting plate 4. Through the movement of the tapered slider 62, the driving resistance block 63 will move away from the inner cylinder 6 again, thereby strengthening the fixation of the engine filter body 7 again, avoiding the problem that the engine filter body 7 will shake frequently during re-testing, thereby affecting the test effect;

[0039] When the airflow detection is lost, the conical slider 62 will return to its original position under the action of the restoring spring 64, and the resistance block 63 will also weaken the fixing effect on the engine filter body 7, which greatly avoids the problem of damaging the engine filter body 7 due to excessive force applied to the engine filter body 7 for a long time.

[0040] A plurality of guide rods 54 are fixedly connected to the interior of the inner chamber 41 , and the elastic connecting ropes 53 are sleeved on the outside of the guide rods 54 .

[0041] A fixing rod 65 is fixedly connected inside the square groove 42 , and a rotating rod 66 is rotatably connected inside the fixing rod 65 .

[0042] A water storage frame 8 is fixedly connected to the top of the workbench 1 . The water storage frame 8 is arranged below the inner cylinder 6 . A water pipe 81 is fixedly connected to the side wall of the water storage frame 8 .

[0043] A testing device 9 is fixedly connected to the top of the workbench 1 .

[0044] Working principle: When testing, the engine filter body 7 needs to be fixed on the device, and the initial position of the connecting plate 4 is in a vertical state. At this time, the resistance block 63 is inside the inner tube 6, and the engine filter body 7 can be sleeved on the outer side of the inner tube 6 without obstacles. When testing, the connecting plate 4 starts to rotate until it is horizontal with the workbench 1, and through the meshing effect of the driven gear 5 and the driving gear 341, the driven gear 5 itself rotates, and the elastic connecting rope 53 is wound around the guide wheel 52, so that the elastic connecting rope 53 can pull the conical slider 62 to move in the direction close to the connecting plate 4. Through the contact between the conical slider 62 and the resistance block 63, the conical slider 62 can squeeze the resistance block 63 out to make it resist the inner wall of the engine filter body 7, thereby achieving a preliminary fixing effect on the engine filter body 7;

[0045] When testing the engine filter body 7, the wind will pass through the square slot 42 and drive the driving blade 67 to rotate. Due to the rotation of the driving blade 67, the elastic connecting rope 53 will be wrapped around the ring 68, so that the elastic connecting rope 53 will pull the tapered slider 62 again to move it toward the connecting plate 4. Through the movement of the tapered slider 62, the driving resistance block 63 will move away from the inner cylinder 6 again, thereby strengthening the fixation of the engine filter body 7 again, avoiding the problem that the engine filter body 7 will shake frequently during re-testing, thereby affecting the test effect;

[0046] When the airflow detection is lost, the conical slider 62 will return to its original position under the action of the restoring spring 64, and the resistance block 63 will also weaken the fixing effect on the engine filter body 7, which greatly avoids the problem of damaging the engine filter body 7 due to excessive force applied to the engine filter body 7 for a long time.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
