Description

Technical Field

[0001] The present invention relates to a network cable fixing device, in particular to a computer network cable fixing device with a self-detection function, belonging to the technical field of computer network cable fixing. Background Art

[0002] In the prior art, such as the invention with the application number 202410535475.4, a computer network cable routing and fixing device is disclosed. In order to solve the problem that some fixing devices achieve the effect of storing redundant wires by controlling the rotation of the wire winding column, but due to the relatively hard network cable, the winding process is time-consuming and laborious, and it is still easy to come out after being pulled later, with insufficient stability. On the other hand, conventional fixing devices can only fix a single long enough network cable. When the length of the network cable is insufficient, the fixing device cannot fix the network cable to the wall anymore. By threading the network cable through the inside of the two frames and then bypassing the side of the guiding mechanism, the folding and winding effect of the wire can be achieved, so as to store the redundant wires and improve the neatness after the network cable routing. The computer network cable routing and fixing device is provided with an extension docking component at the rear end. When the length of the network cable is insufficient, after connecting the network cable to the extension docking component and then connecting it to another network cable, the extension function of the network cable can be achieved, and other main functions can still be achieved in the extended use state.

[0003] The similar applications currently still have deficiencies:

[0004] To ensure the safe use of the network cable, a preliminary detection is required during the assembly of the network cable. However, due to the long length of the network cable, manual detection is time-consuming and laborious. And the current fixing devices also have a fixing function and cannot detect the appearance and durability of the network cable, which affects the service life of the network cable after installation. In addition, during the secondary replacement of the network cable, the length cannot be accurately controlled, resulting in being too long or insufficient, affecting the use effect.

[0005] Therefore, a computer network cable fixing device with a self-detection function is designed to optimize the above problems. Summary of the Invention

[0006] The main object of the present invention is to provide a computer network cable fixing device with a self-detection function. By sliding an L-shaped plate along the width direction inside the housing, a rotating roller and a cross bar are installed on the side of the L-shaped plate, cameras are provided at the top of the L-shaped plate and the bottom of the cross bar, the end of the rotating roller is connected to a rotary encoder, and it is used in cooperation with the counter, image processing module and display screen on the cover plate. The appearance of the network cable can be detected by using the camera in cooperation with the image processing module. The network cable is first wound around the rotating roller and then pulled and conveyed, realizing repeated bending of the network cable, thereby detecting the durability of the network cable. Using the rotation of the rotating roller in cooperation with the rotary encoder and the counter can detect the tensile length of the cable, improving the usability of the device and ensuring the quality and service life of the network cable. By evenly providing a fixing component composed of U-shaped plastic plates, arc-shaped protrusions, plastic cross plates and serrated anti-slip strips along the width direction at both ends inside the housing, the network cable can be separated and positioned during use to ensure the neatness of the line for easy maintenance. In addition, during the fixing process, only need to press the network cable into the inside of the U-shaped plastic plate and then squeeze the two plastic cross plates against each other to complete the positioning of the network cable, which is more convenient for fixing. By fixing a pre-storage mechanism composed of a rectangular block, an arc-shaped groove and a hidden groove on the inner top of the housing and cooperating with a pressing component composed of a fixing plate, a strip-shaped groove, a mounting block, a spring and a pressing roller, it can ensure that the network cable is stored inside the hidden groove so that the network cable can be released for a short distance after the connecting device is displaced, ensuring the connection effect and having higher practicability.

Detailed implementation manners

[0031] To make the technical personnel in this technical field more clear and definite about the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the implementation manners of the present invention are not limited thereto.

[0032] Such as Figure 1 - Figure 8As shown in the figure, this embodiment provides a computer network cable fixing device with a self-detection function, including a housing 1, ear plates 2 fixed at both bottom ends of the housing 1, a cover plate 12 hinged to one side of the top of the housing 1, and a locking mechanism between the housing 1 and the cover plate 12. At both ends of the inner bottom of the housing 1, fixing components 3 are evenly arranged along the width direction. At one end of the inner bottom of the housing 1, a pre-storage component 4 for hiding the network cable is provided. At the other end of the interior of the housing 1, a longitudinal moving mechanism 6 is arranged along the width direction. An L-shaped plate 7 is installed on the longitudinal moving mechanism 6. A roller 8 is rotatably installed inside the L-shaped plate 7. A rotary encoder 11 is installed at the end of the roller 8. At both ends of the inner side of the L-shaped plate 7, cross bars 9 are vertically arranged. Cameras 10 are installed at the top of the L-shaped plate 7 and at positions corresponding to the bottom of the cross bars 9. An image processing module 14 electrically connected to the cameras 10 is installed inside the cover plate 12. A counter 13 is arranged on the side of the image processing module 14. The counter 13 is electrically connected to the rotary encoder 11 through a wire. Both the counter 13 and the image processing module 14 are electrically connected to a display screen 15 through wires.

[0033] Overall working principle: First, fix the position of the device, then pass the network cable after being connected to the device through the housing 1, and use the fixing component 3 to fix the network cable at one end close to the pre-storage component 4. Then wind the other end of the network cable around the surface of the roller 8 and horizontally pull it out from the other end of the housing 1. Since there is a certain resistance between the network cable and the roller 8, the network cable will not slide relative to the roller 8. The pulling of the network cable will control the rotation of the roller 8, driving the rotary encoder 11 to work. The rotary encoder 11 is electrically connected to the counter 13, and the length of the network cable passing through can be measured and displayed through the display screen 15. At the same time, when the network cable passes through the interior of the housing 1, the cameras 10 take pictures of the upper and lower surfaces of the network cable, convert the detected target into an image signal, and transmit it to the special image processing module 14 inside, where it is converted into an analog signal. According to information such as whether there are damages, cracks, or obvious extrusion marks on the outer skin of the network cable, the image processing module 14 calculates these signals to obtain the classification characteristics of the target and then outputs the result, qualified or unqualified, through the display screen 15. In addition, when the network cable wound around the roller 8 is pulled out, the network cable will be bent repeatedly. By detecting the appearance before and after bending, the durability of the network cable can be effectively determined. After a group of network cables are detected, use the fixing component 3 at the other end of the housing 1 to fix the network cable, and then control the sliding of the L-shaped plate 7 through the longitudinal moving mechanism 6. At this time, since both ends of the network cable have been fixed, when the L-shaped plate 7 moves, the network cable wound around the outside of the roller 8 slides off the roller 8, and the network cable inside the housing 1 is in a loose state. Then use the pre-storage component 4 to store the loose network cable for later release and use when the device is relocated.

[0034] In this embodiment, anti-slip patterns are evenly arranged on the outer circumference of the roller 8, and the anti-slip patterns are parallel to the length direction of the roller 8.

[0035] Local working principle: The anti-slip lines on the surface of the rotating roller 8 will increase the resistance when the rotating roller 8 and the wire mesh rotate, which can effectively prevent relative displacement between the wire mesh and the rotating roller 8, ensuring the stability of the rotation of the rotating roller 8. When the wire mesh slides out from the surface of the rotating roller 8, along the length direction of the anti-slip lines, the anti-slip lines will not prevent the wire mesh from sliding out. Instead, it reduces the contact area between the wire mesh and the rotating roller 8, making it more convenient to slide out.

[0036] In this embodiment, the longitudinal moving mechanism 6 includes a chute 28, a slider 29 and a screw 30. The chute 28 is opened at the inner bottom of the housing 1 along the width direction of the housing 1. A screw 30 is rotatably installed between the two ends of the chute 28. A slider 29 fixedly connected to the L-shaped plate 7 is slidably arranged inside the chute 28. The screw 30 is threadedly connected to the slider 29.

[0037] Local working principle: When controlling the movement of the L-shaped plate 7, rotate the screw 30 to control the movement of the slider 29. The slider 29 will drive the L-shaped plate 7 to move linearly towards the vertical side. After fixing a group of wire meshes, the detection and fixing operation of another group of wire meshes is carried out.

[0038] In this embodiment, both ends of the screw 30 extend to the outside of the housing 1, and adjusting blocks are installed at both ends of the screw 30.

[0039] Local working principle: By setting adjusting blocks on the outside of the screw 30, manual adjustment can be carried out without the aid of tools during use, making it more convenient to use.

[0040] In this embodiment, the pre-storage component 4 includes a rectangular block 31, an arc-shaped groove 32 and a hidden groove 33. The rectangular block 31 is fixed at the inner bottom of the housing 1. An arc-shaped groove 32 is opened at the top of the rectangular block 31 along the length direction. Hidden grooves 33 are uniformly opened at the inner bottom of the arc-shaped groove 32 along the length direction. The number of hidden grooves 33 is the same as the number of fixing components 3, and the hidden grooves 33 are located between the connecting lines of the fixing components 3 at opposite positions at both ends of the housing 1. A pressing component 5 is provided on the inner side of the cover plate 12 and at the top of the pre-storage component 4.

[0041] Local working principle: The wire mesh passes over the top of the rectangular block 31. The length of the loose wire mesh is pressed into the arc-shaped groove 32 by the pressing component 5, and after being limited in the hidden groove 33, the wire mesh is in a tensioned state, ensuring the stability of the wire mesh.

[0042] In this embodiment, the pressing component 5 includes a fixing plate 34, a strip-shaped groove 35, a mounting block 36, and a pressing roller 37. The fixing plates 34 are symmetrically installed on both sides of the cover plate 12. Strip-shaped grooves 35 are formed in the fixing plates 34 along the length direction. Mounting blocks 36 are slidably installed inside the strip-shaped grooves 35. A pressing roller 37 is rotatably installed between the two groups of mounting blocks 36.

[0043] Local working principle: After multiple groups of network cables are detected and fixed, the cover plate 12 is closed. At this time, the pressing roller 37 on the cover plate 12 applies a downward pressure on the network cable, pressing the network cable into the hidden groove 33 at the inner bottom of the arc-shaped groove 32. If the length of the network cable is insufficient after the device is moved, at this time, the fixing state of the network cable near the device can be released, and then the network cable is stretched, controlling the upward movement of the pressing roller 37 to pull out a certain length of the network cable to make up for the network cable, and then the fixing component 3 is used to fix the position of the network cable.

[0044] In this embodiment, the fixing component 3 includes a U-shaped plastic plate 24, an arc-shaped protrusion 25, a plastic cross plate 26, and a serrated anti-slip strip 27. The U-shaped plastic plate 24 is fixed to the inner top of the housing 1. Arc-shaped protrusions 25 are provided at the bottom inside the U-shaped plastic plate 24. Plastic cross plates 26 are installed at the top inside the U-shaped plastic plate 24. The plastic cross plates 26 on both sides of the U-shaped plastic plate 24 are in upper and lower contact. Serrated anti-slip strips 27 are provided on the mutually contacting surfaces of the two groups of plastic cross plates 26.

[0045] Local working principle: When fixing the network cable, first press the network cable on the inner bottom of the U-shaped plastic plate 24, and then use two fingers to relatively squeeze both sides of the U-shaped plastic plate 24. At this time, the two groups of plastic cross plates 26 move towards each other, and the serrated anti-slip strips 27 are engaged with each other to lock the position of the U-shaped plastic plate 24. At this time, the arc-shaped protrusion 25 presses the top of the network cable to stabilize the position of the network cable. When releasing the locked state of the network cable, only need to pull the plastic cross plate 26 at the top upward to release the locked state of the two groups of plastic cross plates 26.

[0046] In this embodiment, the locking mechanism includes a hook 16, a slot 17, a stopper 19, and a dragging component. The hook 16 is fixed to one side of the top of the housing 1 away from the hinge of the cover plate 12. A slot 17 cooperating with the hook 16 is formed inside the cover plate 12. A stopper 19 is slidably provided on the side of the slot 17, and a dragging component is provided at the end of the stopper 19.

[0047] Local working principle: When the cover plate 12 is closed, the hook 16 is inserted into the inside of the slot 17, and the stopper 19 is inserted under the hook 16 to lock the position of the hook 16, completing the closing and sealing of the housing 1 and the cover plate 12. If it is necessary to open the housing 1, only need to control the stopper 19 to slide out from inside the hook 16 through the dragging component.

[0048] In this embodiment, the dragging component includes a mounting groove 18, a return spring 20, a through groove 21, a pull rod 22 and a drag plate 23. The mounting groove 18 is opened on the side of the slot 17. The stop block 19 is located inside the mounting groove 18. A return spring 20 is provided between the end of the mounting groove 18 and the end of the stop block 19. A pull rod 22 extending to the top of the cover plate 12 is fixed to the top of the stop block 19. A through groove 21 for limiting the pull rod 22 is opened at the top of the mounting groove 18. A drag plate 23 fitting the surface of the cover plate 12 is fixed to the top of the pull rod 22.

[0049] Local working principle: When controlling the sliding of the stop block 19, the finger is placed on the top of the drag plate 23, and the drag plate 23 is controlled to drive the pull rod 22 to slide, controlling the stop block 19 to slide towards the inside of the mounting groove 18. The stop block 19 is separated from the hook 16, and the locked state is released.

[0050] In this embodiment, the stop block 19 is in the shape of a right trapezoid, and the inclined surface of the stop block 19 is located below the end far from the mounting groove 18.

[0051] Local working principle: When the cover plate 12 is closed, the top of the hook 16 contacts the inclined surface of the stop block 19 and automatically squeezes the stop block 19 into the inside of the mounting groove 18. After the hook 16 is inserted into the slot 17, the stop block 19 automatically inserts into the hook 16 under the action of the return spring 20 for locking, which is more convenient to use.

[0052] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
