Description

Convenient secondary opening type optical cable splice box Technical Field

[0001] The utility model belongs to the technical field of communication equipment, and in particular relates to a convenient secondary opening type optical cable junction box. Background Art

[0002] During the use of the optical cable junction box, it is usually necessary to open it a second time after the first fusion splicing for subsequent expansion or maintenance. Technical issues

[0003] Since the optical cable splice box needs to meet the IP68 protection level, the box body is sealed with non-vulcanized glue with high viscosity. When the installed optical cable splice box needs to be opened again by fiber splicing, the conventional method requires two people to use crowbars to open the box body together. Since the box body is glued with non-vulcanized glue, it is difficult to open the box body, and the box body or the fiber spliced ​​inside the box body may even be damaged during the opening process. Technical Solutions

[0004] In view of the above-mentioned shortcomings, the technical problem to be solved by the present invention is to provide a convenient secondary opening optical cable splice box that can be easily opened by one person.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a convenient secondary opening optical cable junction box, comprising a box body and a cover arranged on the top of the box body, the box body and the cover are sealed together through the edge portion; the box body and the cover are designed to be symmetrical on the left and right, and reinforcing ribs are formed at both ends of the box cover, and through-holes are respectively provided on both sides of the reinforcing ribs on the box cover, and box cover nuts are fixed correspondingly to the through-holes, and the box cover nuts are connected with jacking bolts.

[0006] As a preferred technical solution, the box cover nut is embedded in the through hole.

[0007] As a preferred technical solution, the box cover nut is embedded in the through hole close to one end of the box body.

[0008] As a preferred technical solution, the edge portions at both ends of the box cover are respectively provided with downwardly protruding positioning pins, and the edge portions at both ends of the box body are respectively provided with positioning holes that cooperate with the positioning pins.

[0009] As a preferred technical solution, a plurality of reinforcing ribs are respectively formed on the box body and the box cover. Beneficial effects

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) The box cover is provided with perforations on both sides of the reinforcing ribs, which pass through the edge portion. The perforations are fixed with box cover nuts corresponding to the perforations. The box cover nuts are connected with lifting bolts. When the box body needs to be opened for the second time, the lifting bolts are screwed into the box cover nuts. By screwing the lifting bolts, the lifting bolts will continue to push down on the box body, and the box body and the box cover will be separated by the reaction force. The same operation can be performed on the four corners, and a single person can quickly open the optical cable junction box. Since the box body and the box cover are both designed to be bilaterally symmetrical, when the lifting bolts at the four corners apply force, a uniform reaction force will be generated, and the two ends of the box cover are respectively formed with reinforcing ribs, and the lifting bolts are located on both sides of the reinforcing ribs. In this way, the reaction force generated during the lifting is not easy to cause damage to the box body and the box cover, and there is no need to move the box body violently to avoid damaging the bare fiber.

[0012] (2) The box cover nut is embedded in the perforation of the box cover, and the box cover nut cooperates with the jacking bolt to connect the box cover. In this way, the box cover nut and the jacking bolt are configured as a self-starting tool integrated with the optical cable junction box. When the box body needs to be opened for the second time, the operator does not need to carry or equip additional tools, and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims. Example

[0019] As shown in Figures 1 and 2, a convenient secondary opening optical cable splice box includes a box body 1 and a box cover 2 provided on top of the box body 1, wherein the box body 1 and the box cover 2 are sealed together by the edge portion; the box body 1 and the box cover 2 are respectively designed to be bilaterally symmetrical, and reinforcing ribs 21 are formed at both ends of the box cover 2, and through-holes 22 are provided on both sides of the reinforcing ribs 21 on the box cover 2, which pass through the edge portion up and down, and box cover nuts 23 are fixedly provided at the corresponding through-holes 22, and the box cover nuts 23 are connected with jacking bolts 24. In this embodiment, the box cover nuts 23 are embedded in the through-holes 22. Of course, the box cover nuts 23 can also be fixedly provided at the upper outer side of the through-holes 22, so that the box cover nuts 23 and the through-holes 22 remain concentric, which should all fall within the scope of protection of the present utility model.

[0020] Referring to Figures 1 and 2, when the box body needs to be opened a second time, the jacking bolt 24 is screwed into the box cover nut 23. By screwing the jacking bolt 24, the jacking bolt 24 will continue to push down on the box body 1, and the box body 1 and the box cover 2 will be separated by the reaction force. The same operation can be performed on the four corners, and a single person can quickly open the optical cable junction box. Since the box body 1 and the box cover 2 are both bilaterally symmetrical, when the jacking bolts 23 at the four corners apply force, a uniform reaction force will be generated, and the two ends of the box cover 2 are respectively formed with reinforcing ribs 21, and the jacking bolts 24 are located on both sides of the reinforcing ribs 21. In this way, the reaction force generated during jacking is not easy to cause damage to the box body 1 and the box cover 2, and there is no need to move the box body violently to avoid damaging the bare fiber.

[0021] 3 , downwardly protruding positioning pins 25 are respectively provided on the edge portions at both ends of the box cover 2, and positioning holes cooperating with the positioning pins 25 are respectively provided on the edge portions at both ends of the box body 1, so that when the box cover 2 and the box body 1 are sealed together, the alignment and positioning of the two can be quickly achieved.

[0022] The box body 1 and the box cover 2 are respectively integrally injection-molded, and a plurality of reinforcing ribs 26 are respectively formed on the shells. The reinforcing ribs 26 can improve the shell strength on the basis of a smaller shell thickness. Example

[0023] The structural principles of this embodiment are the same as those of the first embodiment, and the similarities are not repeated here. The only difference is that: referring to Figure 4, in this embodiment, the box cover nut 23 is embedded in the through hole 22 near one end of the box body 1, so that the lifting bolt 24 can be quickly screwed in and pressed against the box body 1, thereby shortening the screwing time for opening.

[0024] The utility model configures the box cover nut and the jacking bolt as a self-starting tool integrated with the optical cable junction box. When the box body needs to be opened a second time, the operator does not need to carry or equip additional tools. The operation is easy to use and there is no need to move the box body violently, thus avoiding damage to the bare fiber.

[0025] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
