Description

Technical Field

[0001] The present invention relates to the field of detection machines, and in particular to an internal frame strength detection tool for an optical cable fiber distribution box. Background Art

[0002] Fiber optic splitter boxes connect distribution cables at the top and household cables at the bottom, making them a crucial component of intelligent fiber management. As demand increases, three-in-one, four-in-one, and even six-in-one fiber optic splitter boxes have been designed. The design of these boxes often requires a complex internal framework to support the associated components. This framework often consists of numerous panels, some made of plastic and some made of metal, depending on the application.

[0003] During the strength testing of the fiber optic splitter box frame, the aforementioned panels often need to be individually tested to ensure the reliability of the internal frame. However, existing equipment can only test a single panel. Therefore, using existing equipment to test the large number of panels contained in the internal frame of the fiber optic splitter box takes a very long time, and the testers need to repeat the test operation over and over again, which is very troublesome.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. The present application has a placement component installed on the cover plate, and the placement component includes a placement table, a pair of placement rollers installed on the placement table, the placement rollers are used to set up the objects to be inspected, and two rows of longitudinal through holes are symmetrically opened on the placement table, and a sliding bar is provided through each through hole, and a baffle is fixed at one end of the sliding bar, and the baffle is fixed to the placement table by a No. 1 spring. Every two horizontal sliding bars are fixed on the same clamping plate, and a large number of panels can be fixed at one time through each clamping plate, thereby facilitating batch inspection of the internal frame panels of the optical cable fiber distribution box.

[0018] 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. Since the splint is higher than the sliding bar, the splint can clamp panels that are much wider than the splint to accommodate larger panels. The sliding bar presses against the bottom of the panel to ensure that the panel will not be crooked, thereby ensuring the accuracy of subsequent test results.

[0019] 3. A pair of push blocks fixed to the cover plate are symmetrically arranged on both sides of the moving assembly. The push blocks are semicircular and located at the bottom of the pressure head. The push blocks are aligned with the baffle. When the plate clamped by each splint is aligned with the pressure head, the two baffles below it will be pushed, thereby driving the splint to stop clamping the plate, so that the plate can be out of contact with the splint during the strength test, ensuring more accurate test results.

[0020] 4. A groove is opened on each sliding bar. After the sliding bar is pushed along with the baffle, the groove will move to the plate position, so that the plate will be out of contact with the sliding bar. In this state, the plate is simply in contact with the two placement rollers, thereby greatly reducing the error of the detection result.

[0021] 5. A connecting seat is fixedly provided on the slider, and a rotating seat is hingedly connected to the connecting seat. The rotating seat is fixed to the placement table, so that the user can manually flip the placement table to facilitate observation of the deformation of the panel, thereby making observation more convenient and improving the user experience.

[0022] 6. A sliding groove is provided on the placement table, and a pair of slides are slidingly arranged in the sliding groove, and each slide is fixed to one of the placement rollers. A No. 2 threaded rod is provided through the two slides, and the No. 2 threaded rod is rotatably connected to the placement table. There are two opposite sections of threads on the No. 2 threaded rod and they are respectively threadedly connected to the two slides. A knob is fixed at one end of the No. 2 threaded rod, and the knob is manually turned to drive the No. 2 threaded rod to rotate. The threaded connection between the No. 2 threaded rod and the slide drives the two slides to move closer or farther away from each other, thereby driving the two placement rollers fixed to the slides to move closer or farther away from each other, so as to adapt to plates of different widths, thereby better carrying the plates.

[0023] 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 the No. 2 spring. The two lifting heads are fixed to the top plate. Protective plates are fixed on both sides of the top plate. The protective plates are used for protection. When the pressure head descends and applies pressure to the plate, the protective plates on both sides will resist the cover plate, and the No. 2 spring is compressed. The protective plates can effectively prevent the damage caused by the explosion of some relatively brittle plastic plates or metal plates.

[0024] 8. The placement table is also provided with display components with the same number as the splints. The display components include a socket set through the placement table, an indicator rod is provided through the socket, a baffle is fixed at one end of the indicator rod, and a fixing seat fixed to the placement table is provided on one side of the baffle. A laser pen is fixed on the fixing seat, and the laser pen is aimed at the baffle. After the plate is bent, the baffle is manually pushed so that the indicator rod fits the corresponding plate. After the laser pen is started, the laser is emitted to the baffle position. By observing the length of each laser, the user can indirectly observe the bending degree of the plate very conveniently, so that the rebound performance of each plate can be judged very intuitively.

DETAILED DESCRIPTION

[0035] Combined with attachment Figures 1-8 The internal frame strength testing 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 screw 33 is rotatably installed in the protective frame 13, and a lifting platform 15 is installed on the two screws 33. The lifting platform 15 is threadedly connected to the two screws 33. A power component is arranged in the base 11 to drive the two screws 33 to rotate together. The two 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 base 16 is fixedly installed at the bottom of the lifting platform 15. The bottom of the sensing base 16 is fixedly connected to a pressure head 27. The pressure head 27 applies pressure to the object to be detected as the lifting platform 15 descends. A pressure sensor is provided in the sensing base 16. The sensing base 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 by the computer system. A console 19 is fixed on the cover plate 12.

[0036] A placement assembly 40 is mounted on the cover plate 12. The placement assembly 40 includes a placement platform 42. A pair of placement rollers 44 are mounted on the placement platform 42. The placement rollers 44 are used to set up the object to be tested. However, this structure is not suitable for the internal frame strength test requirements of the optical fiber distribution box. As mentioned in the background technology, the applicant needs to test a large number of panels during the strength test of the internal frame of the optical fiber distribution box. To this end, the applicant has improved the placement assembly 40. The specific improvements are as follows:

[0037] Two rows of longitudinal through holes 66 are symmetrically provided on the placement table 42, and a sliding bar 46 is slidingly provided on each of the through holes 66, and a baffle 47 is fixed to one end of the sliding bar 46, and the baffle 47 is fixedly connected to the placement table 42 by a No. 1 spring 48. Every two horizontal sliding bars 46 are fixed to the same clamping plate 45, and the top of the clamping plate 45 is higher than the sliding bar 46. The No. 1 spring 48 is in a compressed state so that the clamping plate 45 can fit the placement roller 44. 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. 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. Since 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;

[0038] A motion component 50 is connected to the bottom of the placement component 40 , and the motion component 50 drives the plates clamped by the clamps 45 to align with the pressure head 27 , so that strength testing can be carried out in sequence.

[0039] After conducting actual operations, the applicant discovered that the test results of the plates clamped by the clamping plates 45 would have certain deviations. To this end, the applicant symmetrically provided 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 the plate clamped by each clamping plate 45 is aligned with the pressure head 27, the two baffles 47 thereunder will be pushed, thereby driving the clamping plates 45 to stop clamping the plate, so that the plate can be separated from the clamping plates 45 during the strength test, ensuring more accurate test results.

[0040] Furthermore, during the panel inspection process, the panel will be held against 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 causing the panel to 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.

[0041] 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 52 passes through the slider 51 and is threadedly connected to the slider 51, the threaded rod 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 52 to rotate, and the slider 51 is driven to move by the threaded connection between the threaded rod 52 and the slider 51, and the placement component 40 moves with the slider 51.

[0042] 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 into an articulated type, specifically:

[0043] 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 placement table 42, so that the user can manually flip the placement table 42 to conveniently observe the deformation of the plate, thereby making observation more convenient and improving the user experience;

[0044] 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 be kept in a vertical state for observation of the plate;

[0045] Furthermore, the No. 2 clamping head 25 is fixed on the back side of the placement table 42, and the 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 the 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.

[0046] 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 slidingly arranged in the sliding groove 26, and each of the slides 29 is fixed to one of the placement rollers 44. 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. 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. 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 plates of different widths, thereby better carrying the plates.

[0047] 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 and applies 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 certain relatively brittle plastic plates or metal plates.

[0048] As an embodiment of the present application, a display component 60 having the same number as the splint 45 is further provided on the placement table 42, and the display component 60 includes a socket 64 set through the placement table 42, and an indicator rod 63 is provided through the socket 64, one end of the indicator rod 63 is fixed with a baffle 65, and a fixing seat 61 fixed to the placement table 42 is provided on one side of the baffle 65, and a laser pen 62 is fixed on the fixing seat 61, and the laser pen 62 is aligned with 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 indirectly observe the bending degree of the plate very conveniently, so that the rebound performance of each plate can be judged very intuitively.

Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention.
