Description

Technical Field

[0001] The invention relates to the technical field of computer laboratories, and in particular to a network cable anti-pulling device for a computer laboratory. Background Art

[0002] The background of the computer laboratory network cable anti-unplugging equipment mainly stems from the particularity and challenges of network cable use in laboratory environments. With the widespread application of computer technology in scientific research, teaching and other fields, computer laboratories have become an important place for scientific research and teaching activities. In these places, network cables are key components connecting computers and network devices. Their stability and reliability are crucial to ensuring the normal operation of the laboratory. In daily use in the laboratory, network cables often face the risk of being accidentally unplugged. This is mainly due to the frequent activities of people in the laboratory, which can easily cause entanglement or accidental contact with the network cables. When the length of the network cable is too long or too short, it will also increase the possibility of it being unplugged.

[0003] After searching, the Chinese invention patent number CN117498085A discloses a network cable anti-pulling device for university computer laboratories;

[0004] Compared with the prior art, the anti-pullout rod of the invention patent with Chinese patent number CN117498085A is arranged as a hollow structure, and a wire outlet hole and a wire inlet hole are arranged at both ends of the anti-pullout rod respectively. The cable inserted into the anti-pullout rod is passed out from the wire outlet hole, and after being wound on the anti-pullout rod, it is again inserted into the hollow anti-pullout rod through the wire inlet hole. The cable is wound on the anti-pullout rod, which increases the friction force of the cable on the anti-pullout rod, can increase the resistance of the anti-pullout rod to the movement of the cable, improve the anti-pullout effect of the network cable, and improve the stability of computer operation in the computer laboratory. A connecting rod is arranged on the fastening plate, and the connecting rod is extended into the slide groove through the through groove, and the slide groove is arranged as an arc structure. The surface of the cable fits with the fastening plate of the arc structure. When the network cable is suddenly pulled, the stability of the cable between the fastening plates is enhanced, and the anti-pullout performance of the network cable is improved.

[0005] However, in actual use, the above device is not easy to fix on the computer, which will lead to a series of disadvantages. The stability of the network cable will be greatly reduced. The experimenter is likely to pull the network cable during laboratory activities. This pulling force will directly act on the connection between the network cable and the computer port, increasing the risk of the network cable being accidentally pulled out. The above device can increase the friction of the network cable on the anti-pull rod and increase the resistance of the anti-pull rod to the movement of the cable, but it will generate friction on the network cable while increasing the resistance. In the long run, it will easily cause damage to the network cable. Therefore, it is necessary to propose a computer laboratory network cable anti-pull device. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art that it is difficult to fix on the computer, the stability of the network cable will be greatly reduced, and the resistance will be increased while friction will be generated on the network cable. In the long run, the network cable will be easily damaged. A computer laboratory network cable anti-pulling device is proposed.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] like Figure 1-Figure 7 As shown, a network cable anti-pulling device for a computer laboratory proposed by the present invention comprises a box body 1, a protective shell 2 and a network cable 18, the box body 1 and the protective shell 2 are in contact with each other, a second opening groove 13 is provided on a side of the box body 1 close to the protective shell 2, a first transmission block 14 is fixedly connected to the inner side of the second opening groove 13, a rotating tube 17 is movably connected to the first transmission block 14 on the side close to the protective shell 2, a strong magnetic block 5 is symmetrically and movably connected inside the protective shell 2, a locking assembly is arranged on the inner side of the protective shell 2, the locking assembly comprises a threaded rod 7, a first spring 9 and abutment plate 12, a load-bearing plate 25 is symmetrically and fixedly connected to the end of the protective shell 2 away from the box body 1, a buffer assembly is arranged on the upper part of the load-bearing plate 25, and the buffer assembly comprises a network cable 18, a second spring 22 and a second rotating rod 24;

[0034] A second transmission block 15 is movably connected to a side of the first transmission block 14 close to the protective shell 2, a protection tube 16 is fixedly connected to a side of the second transmission block 15 away from the first transmission block 14, an end of the protection tube 16 away from the first transmission block 14 is rotatably connected to a rotating tube 17, a third opening groove 19 is provided on the outer side of the rotating tube 17, and the inner side of the third opening groove 19 is in contact with the network cable 18;

[0035] The protective shell 2 is fixedly connected with an annular tube 3, and the number of the annular tube 3 is two groups. The inner side of the annular tube 3 is rotatably connected with a first rotating rod 4, and one end of the first rotating rod 4 close to the protective tube 16 is fixedly connected with a strong magnetic block 5;

[0036] The end of the protective shell 2 away from the box body 1 is fixedly connected with a fixing plate 6, and the number of the fixing plates 6 is two sets. The fixing plates 6 are threadedly connected to the threaded rods 7, and the end of the threaded rods 7 close to the protective tube 16 is rotatably connected with the connecting plate 8;

[0037] The side of the connecting plate 8 close to the protective shell 2 is fixedly connected to the first spring 9, and the end of the first spring 9 away from the connecting plate 8 is fixedly connected to the protective shell 2. A first opening groove 10 is provided on the side of the connecting plate 8 close to the protective tube 16, and a connecting rod 11 is fixedly connected to the inner side of the first opening groove 10, and the connecting rod 11 and the abutment plate 12 are movably connected.

[0038] In this embodiment, the protective shell 2 can be adsorbed onto the box body 1 through the magnetic attraction of the strong magnetic attraction block 5, which plays a role in stabilizing and protecting the device. The specific implementation process is that when the protective shell 2 contacts the box body 1, the first rotating rod 4 is rotated. During the rotation of the first rotating rod 4, the strong magnetic attraction block 5 will be driven to rotate. When one side of the rotating strong magnetic attraction block 5 is parallel to the box body 1, the box body 1 and the strong magnetic attraction block 5 will be close to each other due to the action of gravity. The number of strong magnetic attraction blocks 5 is two groups. The two strong magnetic attraction blocks 5 will drive the device to be perpendicular to the box body 1, so that the device can be fixed at the interface of the box body, effectively preventing accidental removal;

[0039] By rotating the threaded rod 7, the plate 12 can be pressed against the protective tube 16, thereby locking the protective tube 16, which can effectively prevent the network cable from being unplugged and plugged in, avoiding network interruption caused by malicious damage or misoperation, thereby enhancing the overall security of the computer laboratory or network environment. The specific implementation process is that in the initial state, the plate 12 can swing left and right in the horizontal direction. When the protective tube 16 moves toward the box body 1, the protective tube 16 will squeeze the plate 12, and the plate 12 will squeeze the connecting plate 8 at the same time. Because the threaded rod 7 and the connecting plate 8 are threadedly connected, the threaded rod 7 needs to be rotated at this time. When the connecting plate 8 is squeezed, the first spring 9 will be squeezed as well. When the protective tube 16 moves to a suitable distance in the horizontal direction, the end of the abutment plate 12 away from the connecting plate 8 will swing to the side close to the box body 1. At this time, the threaded rod 7 needs to be rotated. Since the threaded rod 7 and the connecting plate 8 are rotationally connected, the threaded rod 7 will drive the connecting plate 8 to move toward the side close to the protective tube 16 while rotating. When moving to the appropriate position, the two abutment plates 12 will resist the protective tube 16 at the same time. Due to the action of the threaded rod 7, the connecting plate 8 cannot move to the side away from the protective tube 16, thereby enabling the protective tube 16 to be locked at this position.

[0040] Embodiment 2

[0041] like Figure 1-Figure 7 As shown, based on the first embodiment, a fixing block 20 is fixedly connected to the upper part of the load-bearing plate 25, and the number of the fixing blocks 20 is two groups. A sliding hole 21 is opened inside the fixing block 20, and a sliding block 23 is slidably arranged inside the sliding hole 21;

[0042] A second spring 22 is fixedly connected to a side of the sliding block 23 away from the protective shell 2, and an end of the second spring 22 away from the sliding block 23 is fixedly connected to the fixed block 20;

[0043] The opposite sides of the two sliding blocks 23 are rotatably connected to the second rotating rod 24, and the network cable 18 is spirally wound around the outer side of the second rotating rod 24;

[0044] One end of the abutment plate 12 away from the connection plate 8 is in contact with the protection tube 16, and the size of the annular tube 3 is adapted to the size of the first rotating rod 4;

[0045] The mesh wire 18 is spirally wound around the outer side of the rotating tube 17 , and the outer side of the rotating tube 17 and the outer side of the second rotating rod 24 are in contact with the mesh wire 18 .

[0046] In this embodiment, there are two groups of fixed blocks 20, and a sliding hole 21 is opened inside the fixed block 20. A sliding block 23 is slidably arranged on the sliding hole 21. A second rotating rod 24 is rotatably connected between the two sliding blocks 23. The outer side of the second rotating rod 24 is spirally wound with the network cable 18. When the network cable 18 is pulled by external force, the network cable 18 will drive the second rotating rod 24 to rotate. While the second rotating rod 24 rotates, it will push the fixed block 20 to slide horizontally along the sliding hole 21. While the sliding hole 21 slides, it will squeeze the second spring 22. The function of the second spring 22 is to buffer the tension generated on the network cable 18 until the network cable 18 is separated from the second rotating rod 24. At this time, it will enter the next stage. Because the network cable 18 is wound around the inner side of the third open groove 19, the rotating tube 17 is rotatably connected to the protective tube 16. When the network cable 18 is pulled, the network cable 18 will rotate, thereby driving the rotating tube 17 to rotate. At this time, the tension generated on the network cable 18 will be buffered again.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
