[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Refer to Figure 1 , the submerged optical fiber splice closure 1 is composed of a housing 11 and a cover 12 installed on the top of the housing 11, and a plurality of splices 13 are also provided on the cover 12. In the prior art, for the assembly of the housing 11 and the cover 12, the cover 12 is usually installed by manually pressing the cover 12. However, since there are multiple splices 13 on the cover 12, the directly pressable contact area by hand is limited, which easily leads to uneven force on the cover 12 and the occurrence of the situation where the cover 12 warps, and the labor intensity of direct manual pressing is high.

[0027] Based on this, the present invention provides the following embodiments. Refer to Figures 2-3 , a jig for assembling a submerged optical fiber splice closure, comprising: a base 2 for carrying the submerged optical fiber splice closure 1; a limit seat 3 installed on the base 2 for abutting and limiting the bottom of the submerged optical fiber splice closure 1; a pressing device 4 horizontally and guidingly installed on the base 2 and disposed opposite to the limit seat 3, and a punch 41 is provided on the surface of the pressing device 4 close to the limit seat 3, and a plurality of concave holes 411 corresponding to and fitted with the splices 13 are provided on the punch 41; a driving mechanism 5 installed on the base 2 and located on the side of the pressing device 4 away from the limit seat 3 for pushing the pressing device 4 to press the cover 12 onto the housing 11.

[0028] It can be understood that the base 2 is a component for installing the limit seat 3, the gland press 4 and the driving mechanism 5. For example, it can be a plate-like structure or a workbench, etc., but not limited thereto. The limit seat 3 is a component for abutting and limiting the buried optical fiber splice box 1. For example, it can be a plate structure or a structure arranged with multiple columns, etc., but not limited thereto. The gland press 4 is a component that realizes the pressing and installation of the cover body 12 by combining the punch 41 and the horizontal guiding structure. Its horizontal guiding structure can adopt, for example, a groove-sliding structure or a slide rail guiding structure, etc., but not limited thereto. The concave hole 411 is a structure for avoiding the joint 13. For example, it can be arranged in one-to-one correspondence with the joint 13, or a single concave hole 411 can correspond to multiple joints 13, etc., but not limited thereto. The driving mechanism 5 is a component for pushing the presser to move. For example, it can be an active driving structure such as an electric push rod 53 or a cylinder, or a manual driving structure such as a push rod 53 cooperating with a guide shaft 52, but not limited thereto.

[0029] With such a setting, first place the box body 11 horizontally between the base 2 and the gland press 4, and abut the bottom of the box body 11 against the limit seat 3. Then place the cover body 12 at one end of the box body 11 close to the presser. Finally, drive the presser to move through the driving mechanism 5 to push the cover body 12, and then press and install the cover body 12 on the box body 11. The operation is simple and convenient. And during the pushing process of the presser, the joint 13 on the cover body 12 will be embedded into the concave hole 411, and then the rest of the punch 41 will come into contact with the cover body 12 to expand the contact surface and improve the uniformity of the force on the cover body 12.

[0030] In some embodiments, the base 2 is provided with limit protrusions 6 that are installed between the limit seat 3 and the gland press 4 and are arranged oppositely. The two limit protrusions 6 are used for positioning both sides of the buried optical fiber splice box 1. The limit protrusions 6 can adopt a block structure or a shaft rod structure, etc., but not limited thereto. In this way, after the limit protrusions 6 limit both sides of the gland press 4, the gland press 4 can be prevented from shifting, ensuring the stability during the pressing process.

[0031] In some embodiments, the limit seat 3 is provided with a groove 21 that is fitted with the limit seat 3. It can be understood that the cooperation between the groove 21 and the limit seat 3 is detachable. For example, it can also be detachably installed by using auxiliary connecting parts such as bolts and screws, but not limited thereto. In this way, it is convenient to replace the base 2, and it is also convenient to store after disassembly.

[0032] In some embodiments, a positioning groove 31 that is fitted with the bottom of the buried optical fiber splice box 1 is provided on one side of the limit seat 3 close to the gland press 4. The setting of the groove 21 can quickly position the buried optical fiber splice box 1, and during the pressing process, the buried optical fiber splice box 1 will not shift upward or to one side, ensuring the stability of the pressing process.

[0033] Exemplarily, the capping device 4 further includes a push plate 42 connected to the driving mechanism 5. The punch 41 is installed on the side of the push plate 42 close to the limit seat 3, and the outer circle of the punch 41 is entirely within the outer circle range of the push plate 42. In this way, the punch 41 can better press the cover 12. Further, two guide plates 7 are installed on the base 2 and are horizontally slidably engaged with the push plate 42 on both sides. In this way, the two guide plates 7 and the base 2 form a groove 21 structure, and the push plate 42 can be located in the groove 21 for guiding cooperation.

[0034] In some embodiments, except for the concave hole 411, the surface of the punch 41 close to the limit seat 3 is a vertical plane. It can be understood that since the surface of the cover 12 close to the capping device, except for the joint 13, the remaining part is a plane, so the surface of the punch 41 except for the concave hole 411 being a vertical plane can better fit the cover 12, so as to increase the contact surface and make the pressing force received by the cover 12 more uniform.

[0035] Exemplarily, the driving mechanism 5 includes a bottom plate 51 installed on the base 2. A guide shaft 52 facing the presser is installed on the bottom plate 51. A push rod 53 is inserted into the guide shaft 52 in a guiding manner. One end of the push rod 53 is connected to the presser, and the other end is hinged with a connecting piece 54. The other end of the connecting piece 54 is linked to a grip 55. An articulated portion is formed at the end of the grip 55 close to the connecting piece 54, and the articulated portion is hinged to the bottom plate 51. In this way, by swinging the grip 55 upward to drive the connecting piece 54 and then drive the push rod 53 to move forward, the capping device 4 is pushed to move.

[0036] As mentioned above, it is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
