DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0023] Refer to Figures 1-4, An optical cable fireproof trough box with convenient installation: It includes an optical cable fireproof trough box 1, and a connection component 6 is arranged between the optical cable fireproof trough boxes 1; the connection component 6 includes an upper connection groove 61, a lower connection groove 62 is correspondingly arranged below the upper connection groove 61, ear plates 63 are fixedly connected to the sides of the upper connection groove 61 and the lower connection groove 62, and a number of connection bolts 64 are screwed and installed on the ear plates 63. A bottom support pad 67 is fixedly installed at the bottom of the lower connection groove 62, and transverse anti-slip grooves 68 and longitudinal anti-slip grooves 69 are formed on the bottom support pad 67.

[0024] Through the above settings, the transverse anti-slip grooves 68 and longitudinal anti-slip grooves 69 formed on the bottom support pad 67 enhance the longitudinal and transverse anti-slip performance of the bottom support pad 67, and the bottom support pad 67 strengthens the anti-slip ability at the bottom of the connection component 6.

[0025] In this way, the optical cable fireproof trough box 1 is made of fiberglass.

[0026] Through the above settings, the optical cable fireproof trough box 1 is made of fiberglass, and the fiberglass material has high strength and excellent fireproof performance.

[0027] In this way, transverse stiffening ribs 4 and longitudinal stiffening ribs 5 are fixedly connected to the outer side wall of the optical cable fireproof trough box 1.

[0028] Through the above settings, the transverse stiffening ribs 4 and longitudinal stiffening ribs 5 fixedly connected to the outer side wall of the optical cable fireproof trough box 1 strengthen the overall strength of the optical cable fireproof trough box 1.

[0029] In this way, the transverse stiffening ribs 4 are evenly distributed along the outer wall of the optical cable fireproof trough box 1, the longitudinal stiffening ribs 5 are distributed along the upper and lower outer wall surfaces of the optical cable fireproof trough box 1, and the transverse stiffening ribs 4 and longitudinal stiffening ribs 5 are integrally cast with the optical cable fireproof trough box 1.

[0030] Through the above settings, the transverse stiffening ribs 4 and longitudinal stiffening ribs 5 are integrally cast with the optical cable fireproof trough box 1, which endows the optical cable fireproof trough box 1, the transverse stiffening ribs 4 and the longitudinal stiffening ribs 5 with fireproof performance. In addition, the overall casting method ensures the overall strength of the optical cable fireproof trough box 1.

[0031] In this way, a fireproof body 2 is inserted into the inner side of the optical cable fireproof trough box 1, a number of through holes 3 are formed in the inner side of the fireproof body 2, and the fireproof body 2 is made of rock wool.

[0032] Through the above settings, a number of through holes 3 are provided on the inner side of the fireproof body 2. Optical cables are inserted into the through holes 3, so that a number of optical cables laid inside the optical cable fireproof trough box 1 respectively pass through the number of through holes 3, so that each optical cable is separated by the fireproof body 2. Even when the internal part of the optical cable inside the optical cable fireproof trough box 1 burns out, its fire is separated by the fireproof body 2, and thus it will not affect other optical cables, which fully improves the protection effect on the optical cables and further enhances the practicability of the present utility model.

[0033] In this method, transverse grooves 65 and longitudinal grooves 66 are provided on the inner walls of the upper connection groove 61 and the lower connection groove 62. The size of the transverse groove 65 is adapted to the size of the transverse stiffening rib 4, and the longitudinal groove 66 is adapted to the size of the longitudinal stiffening rib 5.

[0034] Through the above settings, the transverse groove 65 is adapted to the size of the transverse stiffening rib 4, and the longitudinal groove 66 is adapted to the size of the longitudinal stiffening rib 5. When the upper connection groove 61 and the lower connection groove 62 are screwed and sleeved outside the optical cable fireproof trough box 1, the inner transverse groove 65 and longitudinal groove 66 are engaged with the transverse stiffening rib 4 and the longitudinal stiffening rib 5, so that the sliding freedom between the spliced optical cable fireproof trough boxes 1 in the longitudinal direction is also restricted, and the optical cable fireproof trough boxes 1 cannot be pulled out laterally.

[0035] In this method, the bottom support pad 67 is made of rubber.

[0036] Through the above settings, the rubber material has the advantage of anti-slip.

[0037] The working principle of an easily installed optical cable fireproof trough box provided by the present utility model is as follows:

[0038] During use, according to the length to be laid, select an appropriate number of optical cable fireproof trough boxes 1, lay the optical cables through the through holes 3, then lay the ends of each optical cable fireproof trough box 1 end to end, and finally splice them using the connection assembly 6. The upper connection groove 61 and the lower connection groove 62 are sleeved outside the ports of the two optical cable fireproof trough boxes 1, and the transverse grooves 65 and longitudinal grooves 66 inside the upper connection groove 61 and the lower connection groove 62 are engaged with the transverse stiffening rib 4 and the longitudinal stiffening rib 5 at the ends of the optical cable fireproof trough box 1. Subsequently, use the connection bolt 64 to screw the upper connection groove 61 and the lower connection groove 62 together, so that the two optical cable fireproof trough boxes 1 are completed screw splicing. The entire splicing process is relatively convenient and can greatly shorten the laying and installation period of the optical cable fireproof trough box 1.

[0039] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
