[0004] Chinese invention patent application CN110906844A discloses a steel pipe outer circle flatness testing device. This patent application sets multiple dial indicators on a dial indicator fixing rod, but multiple dial indicators cannot move on the dial indicator fixing rod, lacking mobility, and requiring multiple dial indicators, which requires more cost.

[0005] Therefore, there is a need to provide a new type of device for detecting the flatness of a scraper. Utility Model Content

[0006] The main purpose of this invention is to provide a device for detecting the flatness of a scraper, addressing the shortcomings of existing technologies.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A device for detecting the flatness of a toner cartridge scraper includes a base plate on which a fixed platform is mounted. The fixed platform has a placement groove adapted to the shape of the toner cartridge scraper for placing the scraper. A transverse slide rail parallel to the fixed platform is also fixedly mounted on the base plate. A transverse slider that can slide laterally along the transverse slide rail is slidably connected to the transverse slide rail. A connecting member that can move along the transverse slide rail is fixedly mounted on the surface of the transverse slider. A detection upright plate with a gripping portion is fixedly mounted on the surface of the connecting member. The detection upright plate is perpendicular to the transverse slide rail. A longitudinal slide rail is vertically mounted on the detection upright plate. A longitudinal slider that can slide longitudinally along the longitudinal slide rail is slidably connected to the longitudinal slide rail. A dial indicator fixing plate that can move along the longitudinal slide rail is fixedly mounted on the surface of the longitudinal slider. The dial indicator fixing plate holds a dial indicator for detecting the flatness of the toner cartridge scraper surface.

[0009] Preferably, the bottom plate has symmetrical grooves at both ends that are arranged with the transverse slide rail. Each groove has a base that can move along the groove. One end of the base is slidably connected to the groove, and the other end of the base is fixedly connected to the bottom of the fixed platform.

[0010] Preferably, each of the bases is fixedly connected to a limiting plate fixedly mounted on the base plate, and the limiting plate abuts against the bottom of the fixed platform.

[0011] Preferably, limit seats are fixedly installed on both sides of the fixed platform.

[0012] Preferably, a detection fixing plate is provided between the connector and the detection stand plate, the upper surface of the detection fixing plate is fixedly connected to the bottom of the detection stand plate, and the lower surface of the detection fixing plate is fixedly connected to the upper surface of the connector.

[0013] Preferably, a limiting block is fixedly installed on the side wall of the detection plate, and an L-shaped baffle is fixedly installed on the side wall of the dial indicator fixing plate, with the limiting block and the L-shaped baffle on the same side.

[0014] Compared with the prior art, the present invention will have at least the following beneficial effects:

[0015] ①This testing device can quickly detect the flatness of the toner cartridge scraper. The device has a simple structure, is easy to operate, and is conducive to mass production.

[0016] ② This testing device uses a dial indicator to test the flatness of the toner cartridge scraper. When the dial indicator's probe contacts the surface of the toner cartridge scraper, the dial indicator's pointer will point accordingly. If the probe moves back and forth on the surface of the toner cartridge scraper without any change in the pointer, it indicates that the flatness of the toner cartridge scraper surface is good. Conversely, if the pointer changes direction, it indicates that there is a defect in the flatness of the toner cartridge scraper surface.

[0017] ③ A limiting plate is fixedly installed on the side wall of the detection plate, and an L-shaped baffle is fixedly installed on the side wall of the dial indicator fixing plate. The limiting plate and the L-shaped baffle are on the same side. When the longitudinal slider slides down along the longitudinal slide rail, the L-shaped baffle contacts the limiting plate and prevents the longitudinal slider from continuing to slide down along the longitudinal slide rail, thus protecting the device.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0026] like Figures 1 to 4 As shown, the device for detecting the flatness of the toner cartridge scraper includes a base plate 1, on which a fixed platform 2 is mounted. The fixed platform 2 has a placement groove 3 adapted to the shape of the toner cartridge scraper, used to place the scraper. A transverse slide rail 4, parallel to the fixed platform 2, is also fixedly mounted on the base plate 1. A transverse slider 5, which can slide laterally along the transverse slide rail 4, is slidably connected to the transverse slide rail 4. A connecting piece 6, which can move along the transverse slide rail 4, is fixedly mounted on the surface of the transverse slider 5. A detection upright plate 7 with a gripping part 8 is fixedly mounted on the surface of the connecting piece 6. The detection upright plate 7 is perpendicular to the transverse slide rail 4. A longitudinal slide rail 9 is vertically mounted on the detection upright plate 7. A connecting piece 8, which can move along the transverse slide rail 4, is slidably connected to the longitudinal slide rail 9. The longitudinal sliding slider 10 has a dial indicator fixing plate 11 that can move along the longitudinal slide rail 9. The dial indicator fixing plate 11 holds a dial indicator 12 for detecting the flatness of the toner cartridge scraper surface. The principle of the dial indicator 12 for detecting the flatness of the toner cartridge scraper surface is that when the detection needle 13 of the dial indicator 12 contacts the surface of the toner cartridge scraper, the pointer of the dial indicator 12 will have a corresponding direction. If the detection needle 13 moves back and forth on the surface of the toner cartridge scraper without any change in the pointer, it indicates that the flatness of the toner cartridge scraper surface is good. Conversely, if the pointer changes direction, it indicates that there is a defect in the flatness of the toner cartridge scraper surface.

[0027] The working principle of the detection device in this embodiment:

[0028] Place the toner cartridge scraper to be tested in the placement slot 3. Hold the grip part 8 and move the test plate 7 above the placement slot 3. Adjust the position of the longitudinal slider 10 on the longitudinal slide rail 9 so that the test needle 13 of the dial indicator 12 can contact the surface of the toner cartridge scraper in the placement slot 3. Hold the grip part 8 tightly and move the test plate 7 back and forth along the transverse slide rail 4, keeping the test needle 13 in constant contact with the surface of the toner cartridge scraper. Observe the pointer change of the dial indicator 12 to determine the flatness of the surface of the toner cartridge scraper.

[0029] The base plate 1 has symmetrical grooves 14 at both ends of its surface, which are arranged in relation to the transverse slide rail 4. Each groove 14 is equipped with a base 15 that can move along the groove 14. One end of the base 15 is slidably connected to the groove 14, and the other end of the base 15 is fixedly connected to the bottom of the fixed platform 2. This arrangement allows the fixed platform 2 to move longitudinally along the groove 14 towards the transverse slide rail 4. The position of the fixed platform 2 can be adjusted according to the relative position of the dial indicator 12, which is convenient for testing the flatness of the toner cartridge scraper surface.

[0030] Each base 15 is fixedly connected to a limiting plate 16 fixedly installed on the base plate 1. The limiting plate 16 abuts against the bottom of the fixed platform 2. After the position of the fixed platform 2 on the base plate 1 is determined, the limiting plate 16 and the base 15 are fixedly installed on the base plate 1 by fixing screws. If it is necessary to move the fixed platform 2 longitudinally along the slide groove 14 towards the transverse slide rail 4, the fixing screws are removed, the limiting plate 16 is removed, the fixed platform 2 is pushed towards the transverse slide rail 4, and then the limiting plate 16 is fixedly connected to the base 15 by fixing screws, thereby fixing the position of the fixed platform 2.

[0031] Limit seats 17 are fixedly installed on both sides of the fixed platform 2. The limit seats 17 can prevent the fixed platform 2 from tilting to the sides and affecting the detection of the flatness of the drum scraper surface.

[0032] A detection fixing plate 18 is provided between the connector 6 and the detection plate 7. The upper surface of the detection fixing plate 18 is fixedly connected to the bottom of the detection plate 7, and the lower surface of the detection fixing plate 18 is fixedly connected to the upper surface of the connector 6. The setting of the detection fixing plate 18 can ensure that the detection plate 7 remains stable during movement and improve the reliability of the detection plate 7.

[0033] When the dial indicator 12 inside the dial indicator fixing plate 11 moves up and down along the longitudinal slide rail 9 with the longitudinal slider 10, it needs to maintain a proper position. In order to avoid damage to the entire device caused by the longitudinal slider 10 falling too far along the longitudinal slide rail 9, a limit block 19 is fixedly installed on the side wall of the detection plate 7, and an L-shaped baffle 20 is fixedly installed on the side wall of the dial indicator fixing plate 11. The limit block 19 and the L-shaped baffle 20 are on the same side. When the longitudinal slider 10 slides down along the longitudinal slide rail 9, the L-shaped baffle 20 contacts the limit block 19 and prevents the longitudinal slider 10 from continuing to slide down along the longitudinal slide rail 9, thus protecting the device.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
