[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 , which is the first embodiment of the utility model, and this embodiment provides a connection structure, which includes a connection unit 100, the connection unit 100 includes two symmetrical fixing components 101, a slide cylinder 102 fixed to one end of one of the fixing components 101, and a limiting component 103 arranged in the fixing component 101.

[0032] When in use, through the cooperation between the two fixing components 101 and the limiting component 103, two optical cable crossing boxes can be connected to achieve capacity expansion. Through the setting of the slide 102, the two fixing components 101 can slide between each other, so that when connecting two optical cable crossing boxes, they can be extended and retracted according to the positions of the two optical cable crossing boxes. There is no need to move the optical cable crossing boxes, which can save the labor intensity of the staff. After the capacity expansion is completed, due to the setting of the slide 102, space optimization can be achieved by moving an optical cable crossing box to maximize the space utilization.

[0033] Example 2

[0034] Reference Figure 2 to Figure 4 , which is the second embodiment of the utility model, which is different from the first embodiment in that: it also includes a fixing component 101 including a connecting tube 101a, a first groove 101b opened at one end of the connecting tube 101a, a third groove 101d opened at one side of the first groove 101b, and two second grooves 101c symmetrically opened on both sides of the first groove 101b, and the first groove 101b is connected to the outside through the third groove 101d.

[0035] Furthermore, a fourth groove 101e is formed at the other end of one of the connecting tubes 101a, and a sliding groove 101f is formed on the side of the fourth groove 101e.

[0036] By setting the connecting tube 101a, the placement of the optical fibers connected to the two boxes 201 can be achieved. By setting the first groove 101b, the second groove 101c and the third groove 101d, the stable operation of the limiting assembly 103 can be achieved. By sliding cooperation between the fourth groove 101e and the slide groove 101f opened at one end of one connecting tube 101a and the slide tube 102 and the slider 102a fixed at one end of the other connecting tube 101a, the two connecting tubes 101a can be lengthened or shortened. By setting the fourth groove 101e, the slide tube 102 can also be limited to prevent the two connecting tubes 101a from separating when sliding the connecting tube 101a, thereby causing damage to the device.

[0037] Specifically, one end of the slide cylinder 102 is fixed to one end of another connecting cylinder 101a, and the other end of the slide cylinder 102 is fixedly connected to a slider 102a. The slide cylinder 102 is slidably matched with the fourth groove 101e, and the slider 102a is slidably matched with the slide groove 101f.

[0038] The arrangement of the slide cylinder 102 and the slider 102a can ensure stable sliding between the two connecting cylinders 101a.

[0039] Specifically, the limiting assembly 103 includes a slide plate 103a sliding in the first groove 101b, a clamping plate 103b fixed to one end of the slide plate 103a, two fixed plates 103c symmetrically fixed on both sides of one end of the slide plate 103a, and a spring 103d arranged on one side of the fixed plate 103c. The fixed plate 103c is slidably matched with the second groove 101c, and the two ends of the spring 103d are respectively fixed to one side of the fixed plate 103c and one side of the second groove 101c.

[0040] Furthermore, a connecting block 103e is fixedly connected to one side of the slide plate 103a, and the connecting block 103e slides in the third groove 101d. One end of the connecting block 103e located on the outer circle of the connecting tube 101a is fixedly connected to a connecting ring 103f.

[0041] The setting of the slide plate 103a can cooperate with the limiting groove 201c to complete the docking between the connecting tube 101a and the box body 201. The setting of the third groove 101d can provide a thrust for the limiting component 103 to achieve stable fixation of the connecting tube 101a.

[0042] When in use, align the connecting tube 101a with the fifth groove 201b, align the card plate 103b with the limiting groove 201c, and then insert it therein. After insertion, rotate the connecting tube 101a clockwise. At this time, due to the sliding of the limiting groove 201c and the card plate 103b, the card plate 103b will be driven to slide in the direction of the box body 201 during the sliding process. When the card plate 103b moves to the position of the card slot 201d, the spring 103d will pull the slide plate 103a to the first groove 101b, and then the card plate 103b is engaged with the card slot 201d to complete the fixation between the connecting tube 101a and the box body 201; when it needs to be disassembled, first push the connecting ring 103f to move in the direction close to the box body 201, and the connecting ring 103f will drive the slide plate 103a to move through the connecting block 103e. After moving a suitable distance, rotate the connecting tube 101a counterclockwise. After rotating to a suitable angle, remove the connecting tube 101a from the box body 201.

[0043] Example 3

[0044] Reference Figure 5 to Figure 7, which is the third embodiment of the utility model, and is based on the previous two embodiments. This embodiment provides a capacity expansion device for an optical cable junction box, which includes an expansion unit 200, and the expansion unit 200 includes a box body 201, a box cover 202 arranged on one side of the box body 201, and a cover 203 arranged on both sides of the box body 201. The two boxes 201 are fixedly connected by a connecting unit 100.

[0045] The optical fiber can be placed through the box 201, and the fifth groove 201b can be blocked by the cover 203, so that dust can be prevented from entering and causing damage to the equipment in the box 201 when no connection is made.

[0046] Specifically, two through grooves 201a are symmetrically formed on both sides of the box body 201, and a fifth groove 201b is formed at one end of the through groove 201a. The fifth groove 201b is threadably matched with the cover 203, and the fifth groove 201b is adapted to the connecting tube 101a.

[0047] Furthermore, four limiting grooves 201c are formed on one side of the fifth groove 201b, and a clamping groove 201d is formed on one side of the limiting groove 201c. Both the limiting groove 201c and the clamping groove 201d are matched with the clamping plate 103b.

[0048] Furthermore, the limiting groove 201c is divided into a first end L and a second end M.

[0049] From the first end L to the second end M of the limit groove 201c, the distance from the side of the box body 201 gradually increases. This arrangement is to enable the slide plate 103a to move toward the direction of the box body 201 while rotating the connecting tube 101a, and cooperate with the card slot 201d. Through the pushing effect of the spring 103d on the card plate 103b, the card plate 103b can be stably stuck in the card slot 201d, and the connecting tube 101a cannot be disassembled without operating the limit assembly 103, and it is also prevented that the connecting tube 101a is accidentally touched and causes the connecting tube 101a to fall off from the box body 201.

[0050] Furthermore, if the side wall of the box body 201 is relatively thin, a structure that can be fixed on the outside of the box body can be made according to the shape of the fifth groove 201b, the limiting groove 201c and the card groove 201d, so that it can be fixed on the outside of the box body 201 and can be connected and fixed with the connecting tube 101a.

[0051] During use, when the box body 201 needs to be expanded, first remove the cover 203 on the fifth groove 201b, and then pass the optical fiber to be connected through the through groove 201a, the connecting tube 101a and the through groove 201a on the other box body 201 in turn, and the limit assembly 103 can be engaged through the setting of the limit groove 201c and the card slot 201d.

[0052] In summary, when it is necessary to expand the capacity of the optical cable interleaving box, first place another optical cable interleaving box on the same horizontal line as the previously used optical cable interleaving box, leaving a suitable distance between the two. After placement, the optical fiber that needs to connect the two boxes will pass through the through groove 201a, the connecting tube 101a and the through groove 201a on the other box 201 in turn, align the connecting tube 101a with the fifth groove 201b, align the clamping plate 103b with the limiting groove 201c, and then insert it therein. After insertion, rotate the connecting tube 101a clockwise. At this time, due to the sliding of the limiting groove 201c and the clamping plate 103b, the clamping plate 103b will be driven toward the box 201 during the sliding process. When the card plate 103b moves to the position of the card slot 201d, the spring 103d will pull the slide plate 103a to move into the first groove 101b, and then the card plate 103b is engaged with the card slot 201d to complete the fixation between the connecting tube 101a and the box body 201; when disassembly is required, first push the connecting ring 103f to move in the direction close to the box body 201, and the connecting ring 103f will drive the slide plate 103a to move through the connecting block 103e. After moving a suitable distance, rotate the connecting tube 101a counterclockwise. After rotating it to a suitable angle, remove the connecting tube 101a from the box body 201.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
