[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1-9 A telephone line performance testing device includes a mounting box 1. Support frames 2 are fixedly installed at each of the four corners inside the mounting box 1. Support bars 3 are fixedly installed on two support frames 2 on the same side. A support platform 4 is slidably installed between the two support bars 3. A testing computer 6 is mounted on the top of the support platform 4, and a chassis 5 is mounted on the bottom of the support platform 4. The host of the testing computer 6 is installed inside the chassis 5. A connecting cable 7 connects the chassis 5 and the testing computer 6. A support column 8 is fixedly installed inside the mounting box 1. A connection is established between the support column 8, the support platform 4, and the connecting cable 7. The device has a transmission mechanism. During use, in order to make it easier to use the detection computer 6, the support platform 4 is slid out from the two support bars 3 inside the mounting box 1, and the detection computer 6 is pulled out for use. During the process of pulling out the support platform 4, the transmission mechanism drives the cable management block 10 on the support column 8 to move up, so that the excess length of the connecting cable 7 is loosened, allowing the detection computer 6 to move with the support platform 4 without being restricted by the fixed connecting cable 7. When the support platform 4 is retracted, the transmission mechanism drives the cable management block 10 to descend, fixing the excess part of the connecting cable 7 and storing the connecting cable 7.

[0032] As a preferred technical solution in this embodiment, a slider 9 is slidably installed inside the support column 8, and a cable management block 10 is fixedly installed on the side wall of the slider 9. The cable management block 10 is made of rubber material. Cable management grooves are opened on both sides of the cable management block 10. The groove openings near the side wall of the cable management block 10 are smaller. When storing the connecting wire 7, it is necessary to first pry open both sides of the cable management block 10, put the connecting wire 7 into the cable management block 10, and release it. The cable management block 10 returns to its original position, and the connecting wire 7 is confined inside the cable management block 10. When the support platform 4 is inside the mounting box 1, the cable management block 10 is at the bottom. The connecting wire 7 is folded in half and stored, so that the connecting wire 7 is neatly arranged inside the mounting box 1.

[0033] As a preferred embodiment, the transmission mechanism includes a first ball screw 13, which is rotatably mounted inside the support column 8. A first bevel gear 14 is fixedly mounted on the top of the first ball screw 13, and a second bevel gear 16 is rotatably mounted on one side of the first bevel gear 14. The second bevel gear 16 meshes with the first bevel gear 14, and a second ball screw 15 is fixedly mounted on the second bevel gear 16. An mounting plate 17 is fixedly mounted on one end of each of the two support bars 3 near the support column 8. The second ball screw 15 is rotatably engaged with the mounting plate 17, and the second ball screw 15 is threadedly adapted to the support platform 4. During the process of the support platform 4 being pulled out, the second ball screw 15 is threadedly driven, causing the second ball screw 15 to rotate. This drives the first bevel gear 14 through the second bevel gear 16, causing the first ball screw 13 to rotate. This causes the slider 9 to lift the cable management block 10, and the folded part of the connecting cable 7 can also rise, allowing the detection computer 6 to move with the support platform 4.

[0034] As a preferred technical solution of this embodiment, a support block 11 is slidably installed at the bottom end of the cable management block 10, and a first spring 12 is fixedly installed between the support block 11 and the cable management block 10; when the connecting wire 7 passes through the wire holes on both sides of the cable management block 10, in order to ensure that the connecting wire 7 remains slightly taut inside the mounting box 1, the first spring 12 and the support block 11 support the folded part of the connecting wire 7.

[0035] As a preferred embodiment, the support platform 4 is slidably equipped with locking blocks 18 on both sides of the end away from the support column 8. The two locking blocks 18 are respectively fixedly connected to the support platform 4 with second springs 19. The two locking blocks 18 are respectively engaged with the two support bars 3. The end of the support platform 4 away from the support column 8 is provided with a pull groove 20. The end of the locking block 18 near the support bar 3 is set with a pointed shape, so that when the pull groove 20 is pulled by external force, the locking block 18 is squeezed back into the support platform 4 under the action of external force, which facilitates the pullout of the support platform 4. At the same time, when the support platform 4 is inside the mounting box 1, the support platform 4 can be fixed, increasing the stability of the support platform 4.

[0036] As a preferred technical solution of this embodiment, side plates 21 are fixedly installed on both sides of the mounting box 1, and a back plate 22 is fixedly installed on the back of the mounting box 1; when the telephone line performance testing equipment is installed for the first time, the two side plates 21 and the back plate 22 can be removed to install the telephone line performance testing equipment.

[0037] As a preferred technical solution in this embodiment, multiple ventilation holes 23 are provided on both side plates 21, and dustproof nets 24 are fixedly installed on both sides of the inside of the mounting box 1; the ventilation holes 23 facilitate the dissipation of the heat generated by the operation of the internal device of the telephone line performance testing equipment.

[0038] As a preferred technical solution in this embodiment, a sealing door 25 is rotatably connected to the front of the mounting box 1, and an observation window 26 is fixedly installed on the sealing door 25; by observing the inside of the device through the observation window 26, problems inside the device can be directly observed and discovered.

[0039] As a preferred embodiment, the mounting box 1 contains multiple critical protection test system bodies 27. Each critical protection test system body 27 has multiple line connectors 28. The bottom of each line connector 28 has a sliding groove 29. These sliding grooves 29 are respectively formed on the side walls of the critical protection test system bodies 27. Sliding pieces 30 are slidably installed inside each sliding groove 29. Slots 31 are formed on both sides of the inner walls of each sliding groove 29. Sliding posts 32 are slidably installed on both sides of each sliding piece 30. A third spring 33 is fixedly connected between two of the sliding posts 32 and the sliding piece 30. Existing telephone performance testing methods are one-to-one. This device combines multiple critical protection test system bodies 27 into a matrix device, which can connect to 12... The device has 8 telephone lines and can automatically switch to the line via polling through its programmable control function, enabling continuous automatic testing of the telephone lines. After testing the telephone lines, problematic lines need to be marked. Traditionally, this is done by labeling the lines and remembering the corresponding labels to pinpoint the problematic lines. However, since this device can connect to 128 telephone lines, there are many lines, and if the corresponding labels are not recorded in time during comprehensive testing, the labels of problematic lines may be forgotten. This device uses a slot 31, a locking post 32, and a third spring 33 to lock the slider 30 in the position inside the slide groove 29. Different positions of the slider 30 inside the slide groove 29 represent different states of the telephone lines, thus providing a clear indication of the telephone line status.
