Mobile phone shell toughness detection device with protective device

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] see Figure 1-3 , the present invention provides a technical solution: a mobile phone casing toughness detection device with a protective device, comprising a main casing 1, a fixing frame 5, a supporting column 9, a supporting plate 11 and a glass observation window 14. A hydraulic cylinder 2 is provided inside, and an engaging groove 8 is provided on the top surface of the main casing 1. The hydraulic cylinder 2 is connected with the hydraulic telescopic rod 3, and the hydraulic telescopic rod 3 is provided with a scale line 4, and the fixing frame 5 It is located at the top of the hydraulic telescopic rod 3, and the fixing frame 5 is provided with a threaded rod 6. The interior of the fixing frame 5 is provided with a fixing groove 501, and there are two fixing frames 5. At the same time, the fixing frame 5 is about the main casing 1 The center line of the threaded rod 6 is axially symmetrical, which is convenient for fixing the two ends of the housing body 12 and preventing the housing body 12 from moving. The bottom end of the threaded rod 6 is provided with a fixing piece 7, and the length of the threaded rod 6 is greater than the height of the fixing groove 501. And the threaded rod 6 and the fixing frame 5 are threadedly connected, so as to ensure that the threaded rod 6 can firmly fix the housing body 12 through the fixing piece 7, and the interior of the engaging groove 8 is provided with a protective cover 13. The engaging groove 8 It is a rectangular structure, and there is a sliding connection between the snap groove 8 and the protective cover 13, which is convenient for taking and placing the protective cover 13. The support column 9 is arranged on the top surface of the main housing 1, and the support column 9 is provided with a calibration Plate 10, a calibration line 1001 is set in the middle of the calibration plate 10, and the length of the calibration plate 10 is the same as the diameter of the support plate 11, which makes it easier to calibrate the scale line 4, which can improve the accuracy of the data, the support plate 11 is located in the support column 9, and the support plate 11 is provided with a casing body 12, the upper surface of the support plate 11 is provided with a non-slip pad 1101, and the edge of the support plate 11 is an arc structure concave to the center of the circle, so as not to hinder the casing body 12, a glass viewing window 14 is provided on the surface of the protective cover 13.

[0017] Working principle: First, align the bottom end of the scale line 4 on the hydraulic telescopic rod 3 with the calibration line 1001 on the calibration plate 10 so that they are on the same horizontal plane. At this time, the bottom surface of the fixing groove 501 and the top surface of the anti-skid pad 1101 are aligned At the same level, then place the housing body 12 on the support plate 11, place both ends of the housing body 12 in the fixing grooves 501, turn the threaded rod 6 to move the threaded rod 6 downward, and drive the fixing through the threaded rod 6 The sheet 7 moves downward, so that the fixing sheet 7 presses the housing body 12, and at the same time, the housing body 12 is firmly fixed in the interior of the fixing groove 501, and then the protective cover 13 is placed in the engaging groove 8. During the test , move the hydraulic telescopic rod 3 down, the hydraulic telescopic rod 3 drives the fixing frame 5 to move down, the hydraulic telescopic rod 3 moves down slowly until the shell body 12 is broken, and observe the indication on the scale line 4 through the glass observation window 14 , the larger the obtained data, the stronger the toughness of the shell body 12, this is the use method of the mobile phone shell toughness detection device with the protective device, and the content not described in detail in this manual belongs to the professional and technical personnel in the field well-known prior art.

[0018] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or to perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
