They are communication cable assemblies that use one or more optical fibers placed in a sheath as transmission media and can be used individually or in groups. Optical cables are mainly composed of optical fibers (glass fibers as thin as hair) and plastic protective sheaths and plastic outer sheaths. There is no metal such as gold, silver, copper, aluminum, etc. in the optical cables, and they generally have no recycling value. The basic structure of optical cables is generally composed of several parts such as cable core, reinforcing steel wire, filler and sheath. In addition, there are also components such as waterproof layer, buffer layer, insulated metal wire, etc. as needed.

Utility Model Content

[0005] The utility model aims to solve the shortcoming that the optical cable is difficult to cut in the prior art, and proposes a communication optical cable which is easy to cut.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a communication optical cable that is easy to cut, including an outer shell and a cutting device, a braided sleeve is arranged inside the outer shell, a rubber insulating sleeve is arranged inside the braided sleeve, a cable core is arranged inside the rubber insulating sleeve, a hand-grip tube is arranged on the surface of the outer shell, the cutting device is arranged inside the hand-grip tube, the cutting device includes a connecting block and a pressing hole, the connecting block is fixedly connected to the inside of the hand-grip tube, the pressing hole is opened inside the connecting block, and a cutting knife is slidably connected to the inner wall of the pressing hole.

[0007] Preferably, one end of the cutting knife is fixedly connected to a pressure plate, and a slide groove is provided inside the pressure hole.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, the communication optical cable is a channel for transmitting sexual information, and the sexual information to be transmitted is transmitted through light particles. When the device is used for cutting, when the user presses the pressure plate, the pressure plate moves to drive the slider to move, and the movement of the slider drives the first spring to deform and generate elastic force. When the pressure plate moves, it drives the cutting knife to cut the surface of the shell, and then the user pulls the hand grip tube to cut the shell. By setting up a cutting device, the cable is effectively cut, which plays a role in cutting the cable, reduces the need for the user to cut the optical cable when installing the optical cable when the device is in use, and the cutting of the optical cable requires the use of special tools for operation, which is relatively cumbersome, making the device difficult to popularize, thereby improving the practicality of the device.

[0015] 2. In the utility model, by setting a limiting device, when using the equipment, the user holds the air duct with his hand, and then pushes against the push ring. When the push ring moves, it drives the sliding rod to move. When the sliding rod moves, it drives the second spring to displace and deform to generate elastic force. When the push ring moves, it drives the limit rod to move out of the limit groove. Then the pressure plate loses its restraint. By setting a limiting device, the pressure plate is effectively restricted, which plays a role in restricting the pressure plate, reduces the risk of users accidentally touching the pressure plate when using the equipment, causing cutting of the surface of the outer shell, and improves the stability of the equipment.

[0024] In this embodiment: the cutting device 6 is arranged inside the hand-held tube 5, and the cutting device 6 includes a connecting block 67 and a pressing hole 63. The connecting block 67 is fixedly connected to the inside of the hand-held tube 5, and the pressing hole 63 is opened inside the connecting block 67.

[0025] Specifically, one end of the cutting blade 61 is fixedly connected to a pressure plate 62 , and a slide groove 64 is provided inside the pressure hole 63 .

[0026] In this embodiment: by fixing the pressure plate 62 at one end of the cutting knife 61, the cutting knife 61 can be pressed and moved, thereby reducing the situation where the cutting knife 61 is difficult to move when the device is in use.

[0027] Specifically, a sliding block 65 is fixedly connected to the side of the pressure plate 62 , and the sliding block 65 is slidably connected inside the sliding groove 64 . The sliding block 65 is provided to facilitate the movement of the pressure plate 62 .

[0028] Specifically, one end of the slider 65 is fixedly connected to a first spring 66 , and one end of the first spring 66 away from the slider 65 is fixedly connected to the inner wall of the slide groove 64 . The first spring 66 is provided to facilitate applying elastic force to the slider 65 .

[0029] In this embodiment: a limiting device 7 is provided on the surface of the hand-grip tube 5, and the limiting device 7 includes a resist ring 71 and a limiting rod 74. The resist ring 71 is slidably connected to the surface of the hand-grip tube 5, and the limiting rod 74 is fixedly connected to the side of the resist ring 71. A limiting groove 73 is provided on the side of the pressure plate 62, and the limiting rod 74 is clamped with the inner wall of the limiting groove 73. One end of the resist ring 71 is fixedly connected to a sliding rod 75.

[0030] In this embodiment: by providing a limit rod 74 on the side of the retaining ring 71, the pressure plate 62 can be restricted, thereby reducing the risk of accidental collision of the pressure plate 62 when the device is in use.

[0031] Specifically, a support hole 72 is opened on the surface of the hand-grip tube 5, and a slide rod 75 is slidably connected to the inner wall of the support hole 72. The slide rod 75 is provided to facilitate the limiting of the support ring 71.

[0032] Specifically, a second spring 76 is fixedly connected to the surface of the butt ring 71, and one end of the second spring 76 away from the butt ring 71 is fixedly connected to the surface of the grip tube 5.

[0033] Working principle: Communication optical cable is a channel for transmitting information, and the information to be transmitted is transmitted through light particles. When using the equipment for cutting, when the user presses the pressure plate 62, the pressure plate 62 moves to drive the slider 65 to move, and the movement of the slider 65 drives the first spring 66 to displace and deform to generate elastic force. When the pressure plate 62 moves, it drives the cutting knife 61 to cut the surface of the outer shell 1, and then the user pulls the hand grip tube 5 to cut the outer shell 1. By setting up the cutting device 6, the cable is effectively cut, which plays a role in cutting the cable, reducing the need for the user to cut the optical cable when installing the optical cable when the equipment is in use. The cutting of the optical cable requires the use of special tools for operation, and the operation is relatively cumbersome, which makes the equipment difficult to popularize and improves the practicability of the equipment.

[0034] When the user holds the air duct in his hand, the push ring 71 is pushed, and the push ring 71 moves, which drives the slide bar 75 to move. When the slide bar 75 moves, it drives the second spring 76 to displace and deform to generate elastic force. When the push ring 71 moves, it drives the limit rod 74 to move out of the limit groove 73, and then the pressure plate 62 is freed from the restraint. By setting the limiting device 7, the pressure plate 62 is effectively restricted, which plays a role in restricting the pressure plate 62, reduces the risk of users accidentally touching the pressure plate 62 when the device is in use, causing cutting of the surface of the shell 1, and improves the stability of the device.
