Description

Technical Field

[0001] The utility model belongs to the technical field of optical fibers, and in particular relates to a reel without fasteners for storing optical fibers. Background Art

[0002] Optical fiber is short for optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total reflection of light". With the continuous development of optical fiber communication technology, the application of optical fiber is becoming more and more extensive. During the storage and transportation of optical fiber, how to effectively protect the optical fiber from damage has become an important issue.

[0003] Traditional fiber optic reels usually use fasteners to fix the optical fiber, such as screws, nuts or clips. However, these fasteners may cause pressure and potential damage to the optical fiber. During the rotation, handling or vibration of the reel, the fasteners may rub or collide with the optical fiber, causing scratches or breaks on the optical fiber surface. In addition, the use of fasteners also increases the complexity and cost of the reel.

[0004] In order to avoid these problems, a more reliable and efficient fiber optic reel design is needed. The concept of fastener-free reel came into being, which aims to provide a reel structure without the use of fasteners to reduce the risk of damage to the optical fiber and improve the convenience of reel operation.

[0005] Existing fastener-free reel designs present some challenges in protecting optical fibers. For example, some reels may lack effective isolation measures, resulting in the optical fiber being wound in many layers on the reel. These multiple layers of winding cause the optical fiber surfaces to contact each other, which can easily cause surface wear and damage.

[0006] To this end, we propose a fastener-free reel for optical fiber storage, which can prevent the upper optical fiber surface from contacting the lower optical fiber surface during winding, causing surface damage to the optical fiber due to some reasons (such as vibration and friction) during storage and transportation. Utility Model Content

[0007] The purpose of the utility model is to provide a fastener-free reel for storing optical fiber, which can prevent the upper optical fiber surface from contacting the lower optical fiber surface during winding, causing the optical fiber surface to be damaged due to some reasons (such as vibration and friction) during storage and transportation.

[0008] The technical solutions adopted in this utility are as follows:

[0009] A fastener-free reel for storing optical fiber, comprising a reel body, wherein the reel body is composed of two limit plates and a connecting shaft arranged between the two limit plates, and both limit plates are provided with an anti-contact component;

[0010] The anti-contact component includes a plurality of groups of arc grooves opened on the two limit plates, each group of the arc grooves has two arc grooves, all of which are symmetrically arranged with respect to the center position of the limit plates, each arc groove is provided with a matching arc isolation plate inside, each arc isolation plate is provided with a push rod on one side, and a magnetic surface is provided on the side of the arc isolation plates corresponding to every two positions that are close to each other, and the two magnetic surfaces attract each other.

[0011] Furthermore, the top surface and the bottom surface of the arc-shaped isolation plate are both provided with a first rubber layer.

[0012] Furthermore, the diameter of the push rod is smaller than the width of the arc-shaped isolation plate.

[0013] Furthermore, the diameters of the plurality of groups of arc-shaped grooves decrease successively from top to bottom.

[0014] Furthermore, an L-shaped connecting rod is provided on one of the pushing rods, and a clamping plate is provided on the L-shaped connecting rod.

[0015] Furthermore, a through slot is formed on the top of the limiting plate.

[0016] The technical effects achieved by this utility model are:

[0017] First, when people are winding and storing the optical fiber, one end of the optical fiber is fixed on the connecting shaft, and then it is wound. When the wound optical fiber covers the surface of the connecting shaft, the two symmetrical arc-shaped isolation plates on the left limit plate are pushed between the two limit plates by the push rod, and then the two symmetrical arc-shaped isolation plates on the right limit plate are pushed between the two limit plates by the push rod. Figure 3 As shown in the first figure, at this time, the two arc-shaped isolation plates on the top are fixed by magnetic attraction, and the two arc-shaped isolation plates on the bottom are fixed by magnetic attraction. The four arc-shaped isolation plates form a fixed axis that can be wound, and then the optical fiber is wound around this fixed axis. When the optical fiber covers the entire fixed axis, another set of arc-shaped isolation plates is assembled again, and this process is repeated in sequence to prevent the upper optical fiber surface from contacting the lower optical fiber surface during winding, causing surface damage to the optical fiber due to some reasons during transportation.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0026] like Figure 1-5 As shown, the technical solution adopted by the utility model is as follows: a fastener-free reel for storing optical fibers, comprising a reel body 1, the reel body 1 is composed of two limit plates 2 and a connecting shaft arranged between the two limit plates 2, and the two limit plates 2 are both provided with an anti-contact component;

[0027] The anti-contact component includes multiple groups of arc grooves 4 opened on two limit plates 2, each group of arc grooves 4 has two arc grooves 4, all of which are symmetrically arranged with respect to the center position of the limit plate 2, each arc groove 4 is provided with a matching arc isolation plate 5 inside, each arc isolation plate 5 is provided with a push rod 6 on one side, and a magnetic surface 7 is provided on the side where the arc isolation plates 5 corresponding to every two positions are close to each other, and the two magnetic surfaces 7 attract each other.

[0028] Its working principle is as follows: first, when people are winding and storing the optical fiber, one end of the optical fiber is fixed on the connecting shaft, and then winding is performed. When the wound optical fiber covers the surface of the connecting shaft, at this time, the two symmetrical arc-shaped isolation plates 5 on the left limit plate 2 are pushed between the two limit plates 2 by the push rod 6, and then the two symmetrical arc-shaped isolation plates 5 on the right limit plate 2 are pushed between the two limit plates 2 by the push rod 6. Figure 3As shown in the first figure, at this time, the two top arc-shaped isolation plates 5 are fixed by attracting each other through the magnetic surfaces 7, and the two bottom arc-shaped isolation plates 5 are fixed by attracting each other through the magnetic surfaces 7. The four arc-shaped isolation plates 5 form a fixed axis that can be wound, and then the optical fiber is wound around the fixed axis. When the optical fiber covers the entire fixed axis, another set of arc-shaped isolation plates 5 is assembled again, and this is repeated in sequence, so as to prevent the upper optical fiber surface from contacting the lower optical fiber surface during winding, causing surface damage to the optical fiber due to some reasons during transportation.

[0029] Among them, the utility model has four groups of multiple arc grooves 4, namely the first arc groove 11, the second arc groove 12, the third arc groove 13 and the fourth arc groove 14. By setting four groups of arc grooves, it is possible to cope with the winding of longer optical fibers.

[0030] At the same time, the top and bottom surfaces of the arc-shaped isolation plate 5 are both provided with a first rubber layer, and the first rubber layer can prevent the optical fiber from contacting the arc-shaped isolation plate 5 and causing damage when it is shaken.

[0031] It should be noted that there is a gap between the two arc-shaped isolation plates 5 for winding the optical fiber, and the gap allows the optical fiber to pass through and be wound.

[0032] The diameter of the push rod 6 is smaller than the width of the arc-shaped isolation plate 5. This arrangement enables the push rod 6 to enter the arc-shaped groove 4, so that the arc-shaped isolation plates 5 can fit and attract each other.

[0033] The diameters of the multiple groups of arc-shaped grooves 4 decrease from top to bottom, and this arrangement enables better winding and covering of the optical fiber.

[0034] When the optical fiber is wound to the last end, in order to prevent it from falling off, an L-shaped connecting rod 8 is provided on one of the pushing rods 6 , and a clamping plate 9 is provided on the L-shaped connecting rod 8 .

[0035] like Figure 3 As shown, when the optical fiber is wound onto the last layer of arc-shaped isolation plate 5, the push rod 6 drives the L-shaped connecting rod 8 to allow the clamping plate 9 to fix the other end. Because of the attraction of the magnetic surface 7, it is fixed, thereby achieving fixation without a fixing part.

[0036] One of the push rods 6 is the push rod 6 located at the top, and this arrangement enables the winding to be fixed by the top push rod 6 after the winding is completed.

[0037] In order to prevent the clamping plate 9 from shrinking and moving, a through slot 10 is provided on the top of the limiting plate 2, and the clamping plate 9 can be moved through the through slot 10.

[0038] At the same time, in order to prevent the clamping plate 9 from damaging the optical fiber when clamping, a second rubber layer is provided on the clamping plate 9, and the second rubber layer can be deformed to prevent damage to the optical fiber.

[0039] The utility model is used to roll up optical fiber and then store and transport it, so as to prevent the upper optical fiber surface from contacting and rubbing with the lower optical fiber surface during storage and transportation, causing surface damage of the optical fiber due to some reasons during transportation. The utility model is stored after being rolled up by the reel.

[0040] The working principle of the utility model is as follows: first, when people are winding and storing the optical fiber, one end of the optical fiber is fixed on the connecting shaft, and then winding is performed. When the wound optical fiber covers the surface of the connecting shaft, at this time, the two symmetrical arc-shaped isolation plates 5 on the left limit plate 2 are pushed between the two limit plates 2 by the push rod 6, and then the two symmetrical arc-shaped isolation plates 5 on the right limit plate 2 are pushed between the two limit plates 2 by the push rod 6. Figure 3 As shown in the first figure, at this time, the two top arc-shaped isolation plates 5 are fixed by attracting each other through the magnetic surfaces 7, and the two bottom arc-shaped isolation plates 5 are fixed by attracting each other through the magnetic surfaces 7. The four arc-shaped isolation plates 5 form a fixed axis that can be wound, and then the optical fiber is wound around the fixed axis. When the optical fiber covers the entire fixed axis, another set of arc-shaped isolation plates 5 is assembled again, and this is repeated in sequence, so as to prevent the upper optical fiber surface from contacting the lower optical fiber surface during winding, causing surface damage to the optical fiber due to some reasons during transportation.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
