[0014] 2. The top of the splint is higher than the sliding bar. Under the elastic force of spring No. 1, the panel can be clamped by the part of the splint that is higher than the sliding bar.

[0019] 7. Lifting rails are fixedly installed on both sides of the pressure head, and the lifting head is slidably installed in the lifting rails. The lifting head and the lifting rails are fixedly connected by a No. 2 spring. The two lifting heads are fixed to the top plate. Protective plates are fixed on both sides of the top plate.

DETAILED DESCRIPTION

[0024] Combined with Figure 1-Figure 8 The internal frame strength detection tool of the optical cable fiber distribution box includes a base 11, a cover plate 12 is arranged on the top of the base 11, and a protective frame 13 is symmetrically fixedly installed on both sides of the base 11. A lead screw 33 is rotatably installed in the protective frame 13, and a lifting platform 15 is commonly installed on the two lead screws 33. The lifting platform 15 is threadedly connected to the two lead screws 33. A power component is arranged in the base 11 to drive the two lead screws 33 to rotate together. The two lead screws 33 are driven to rotate simultaneously by the power component. The screw 33 is threadedly connected to the lifting platform 15 to drive the lifting platform 15 to move up and down. A sensing seat 16 is fixedly installed at the bottom of the lifting platform 15. A pressure head 27 is fixedly connected to the bottom of the sensing seat 16. The pressure head 27 applies pressure to the object to be detected as the lifting platform 15 descends. A pressure sensor is arranged in the sensing seat 16. The sensing seat 16 is used to receive the force data of the pressure head 27 and feed it back to the computer system of the present application. The data can be observed through the computer system. A console 19 is fixed on the cover plate 12. A placement assembly 40 is installed on the cover plate 12, and the placement assembly 40 includes a placement table 42, on which a pair of placement rollers 44 are installed, and the placement rollers 44 are used to set up the object to be detected. However, this structure is not suitable for the internal frame strength detection requirements of the optical cable fiber distribution box. As mentioned in the background technology, the applicant needs to detect a large number of panels during the strength detection of the internal frame of the optical cable fiber distribution box. For this reason, the applicant has improved the placement assembly 40, and the specific improvements are as follows: Two rows of longitudinal through holes 66 are symmetrically provided on the placement platform 42, and a sliding bar 46 is slidably provided on each of the through holes 66, and a baffle 47 is fixed at one end of the sliding bar 46, and the baffle 47 is fixedly connected to the placement platform 42 by a No. 1 spring 48, and every two transverse sliding bars 46 are fixed on the same clamping plate 45, and the top of the clamping plate 45 is higher than the sliding bar 46, and the No. 1 spring 48 is in a compressed state so that the clamping plate 45 can fit the placement roller 44, and the clamping plate 45 is manually pulled out, and the bottom of the plate is placed between the clamping plate 45 and the placement roller 44, and under the elastic force of the No. 1 spring 48, the plate can be clamped by the part of the clamping plate 45 that is higher than the sliding bar 46, and because the clamping plate 45 is higher than the sliding bar 46, the clamping plate 45 can clamp a plate that is much wider than the clamping plate 45, and the sliding bar 46 presses against the bottom of the plate to ensure that the plate will not be crooked; A motion component 50 is connected to the bottom of the placement component 40, and the motion component 50 is used to drive the plates clamped by the clamps 45 to align with the pressure head 27, so that strength detection can be carried out in sequence.

[0025] After actual operation, the applicant found that the plate clamped by the clamping plate 45 would have a certain deviation in the test results. For this reason, the applicant symmetrically arranged a pair of push blocks 28 fixed to the cover plate 12 on both sides of the motion component 50. The push blocks 28 are semicircular and located at the bottom of the pressure head 27. The push blocks 28 are aligned with the baffles 47. When each plate clamped by the clamping plate 45 is aligned with the pressure head 27, the two baffles 47 below it will be pushed, thereby driving the clamping plate 45 not to clamp the plate, so that the plate can be out of contact with the clamping plate 45 during the strength test, ensuring more accurate test results. Furthermore, during the panel inspection process, the panel will be blocked by the sliding bar 46 and affect the inspection result. In order to avoid this, a groove 49 is opened on each of the sliding bars 46. After the sliding bar 46 is pushed along with the baffle 47, the groove 49 will move to the panel position, thereby making the panel break away from the contact with the sliding bar 46. In this state, the panel is simply in contact with the two placement rollers 44, thereby greatly reducing the error of the inspection result.

[0026] Among them, the motion component 50 includes a slide rail 53 fixed to the cover plate 12, a slider 51 is slidably installed in the slide rail 53, a threaded rod No. 1 52 penetrates the slider 51 and is threadedly connected to the slider 51, the threaded rod No. 1 52 is fixed to the motor shaft of the motor 55, and the motor 55 is fixed to the motor seat 54 fixed on the base 11. After the motor 55 is started, it will drive the threaded rod No. 1 52 to rotate, and the slider 51 is driven to move through the threaded connection between the threaded rod No. 1 52 and the slider 51, and the placement component 40 moves with the slider 51.

[0027] As an embodiment of the present application, the applicant believes that the placement component 40 placed flat will affect the user's viewing. Therefore, the applicant makes the connection between the placement component 40 and the slider 51 hinged, specifically: A connecting seat 22 is fixedly provided on the slider 51, and a rotating seat 23 is hingedly connected to the connecting seat 22. The rotating seat 23 is fixed to the placing table 42, so that the user can manually flip the placing table 42 to conveniently observe the deformation of the plate, thereby making observation more convenient and improving the user's experience; Furthermore, a pair of No. 1 clamping heads 20 are fixed on the slide rail 53, and a pair of No. 1 clamping seats 21 are fixed on the placement table 42. The No. 1 clamping heads 20 match the No. 1 clamping seats 21, and the No. 1 clamping heads 20 are clamped into the No. 1 clamping seats 21 to achieve fixation, so that the placement table 42 can maintain a vertical state for observation of the plate; Furthermore, a No. 2 clamping head 25 is fixed on the back side of the placement table 42, and a No. 2 clamping seat 24 is fixed on the slider 51. The No. 2 clamping head 25 matches the No. 2 clamping seat 24. After the placement table 42 is flipped to a horizontal position, the No. 2 clamping head 25 is clamped into the No. 2 clamping seat 24 to be fixed, so that the placement table 42 can maintain a stable horizontal state, which is convenient for the subsequent pressure application of the pressure head 27.

[0028] As an embodiment of the present application, a sliding groove 26 is opened on the placement table 42, and a pair of slides 29 are slidably arranged in the sliding groove 26, each of the slides 29 is fixed to one of the placement rollers 44, and a No. 2 threaded rod 34 is provided through the two slides 29, and the No. 2 threaded rod 34 is rotatably connected to the placement table 42, and there are two opposite sections of threads on the No. 2 threaded rod 34 and they are respectively threadedly connected to the two slides 29, and a knob 43 is fixed at one end of the No. 2 threaded rod 34, and the knob 43 is manually rotated to drive the No. 2 threaded rod 34 to rotate, and the threaded connection between the No. 2 threaded rod 34 and the slide 29 is used to drive the two slides 29 to move closer to or away from each other, thereby driving the two placement rollers 44 fixed to the slide 29 to move closer to or away from each other, so as to adapt to panels of different widths, thereby better carrying the panels.

[0029] As an embodiment of the present application, lifting rails 32 are fixedly installed on both sides of the pressure head 27, and a lifting head 30 is slidably installed in the lifting rails 32. The lifting head 30 and the lifting rails 32 are fixedly connected by a No. 2 spring 31. The two lifting heads 30 are fixed to the top plate 17. Protective plates 18 are fixed on both sides of the top plate 17. The protective plates 18 are used for protection. When the pressure head 27 descends to apply pressure to the plate, the protective plates 18 on both sides will resist the cover plate 12, and the No. 2 spring 31 is compressed. The protective plates 18 can effectively prevent the damage caused by the explosion of some relatively brittle plastic plates or metal plates.

[0030] As an embodiment of the present application, a display component 60 having the same number as the clamping plate 45 is further provided on the placement table 42, and the display component 60 includes a socket 64 arranged through the placement table 42, an indicator rod 63 is arranged through the socket 64, a baffle 65 is fixed at one end of the indicator rod 63, and a fixing seat 61 fixed to the placement table 42 is provided on one side of the baffle 65, a laser pen 62 is fixed on the fixing seat 61, and the laser pen 62 is aimed at the baffle 65. After the plate is bent, the baffle 65 is manually pushed so that the indicator rod 63 fits the corresponding plate. After the laser pen 62 is started, the laser is emitted to the position of the baffle 65. By observing the length of each laser, the user can easily and indirectly observe the bending degree of the plate, thereby being able to judge the resilience of each plate very intuitively.

[0031] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
