Preferably, the inner shell is completely embedded in the bridge frame body, and a support strip is arranged on the lower portion of the second bottom plate and is an elastic piece.

Preferably, gaps are left among the supporting bars.

Preferably, the upper end of the bridge frame body is provided with a turnover plate, the turnover plate is connected in the turnover extending edge in a sliding mode, and the turnover plate and the turnover extending edge are matched with the sliding groove in a sliding mode after being embedded.

Preferably, the inner housing is partially embedded in the bridge body.

Preferably, the middle part of the cover body is in a shape of a pitched roof, and the cover body is in close fit sliding connection with the inner shell.

Compared with the prior art, the utility model discloses following beneficial effect has:

the cable bridge comprises a bridge body and is characterized in that the bridge body comprises a first bottom plate and a first side wall, an upward upper rack is arranged on the inner side of the first side wall, the inner shell comprises a second bottom plate and a second side wall, a downward lower rack is arranged on the outer side of the second side wall, the lower rack is matched with the upper rack in a meshing manner, the inner shell is completely embedded in the bridge body, the cable pressure on the inner shell can be effectively distributed on the bottom plate and the side plate of the bridge body, stress concentration is avoided, the service life of the bridge is prolonged, and deformation of the bridge is avoided;

when the inner shell part is embedded in the bridge frame body, the longitudinal space in the bridge frame is increased, so that more cables can be borne, the cables can be layered up and down, and the cables of different specifications are prevented from being wound mutually.

Fig. 2 is a structural diagram of the inner shell part of the bridge frame of the present invention embedded in the bridge frame body.

Fig. 3 is an exploded view of the present invention.

The figure is as follows: the bridge frame comprises a bridge frame body 1, a first side wall 11, a first bottom plate 12, a turnover plate 13, an upper rack 14, a cover body 2, a sliding groove 21, an inner shell 3, a turnover edge 31, a second side wall 32, a second bottom plate 33, a support strip 34 and a lower rack 35.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1-3, a bridge frame with high strength and adjustable accommodating height includes a bridge frame body 1, an inner housing 3, and a cover body 2, where the bridge frame body 1 includes a first bottom plate 12 and a first side wall 11, an upward upper rack 14 is disposed on an inner side of the first side wall 11, the inner housing 3 includes a second bottom plate 33 and a second side wall 32, a downward lower rack 35 is disposed on an outer side of the second side wall 32, the lower rack 35 is in tooth fit with the upper rack 14, a turned extension edge 31 is disposed on an upper end of the second side wall 32, the inner housing 3 is embedded in the bridge frame body 1, a middle portion of the cover body 2 is in a pitched roof shape, the cover body 2 is in tight fit and sliding connection with the inner housing 3, sliding grooves 21 are disposed on two sides of the cover body 2, and the sliding fit between the sliding grooves 21 and the turned extension edge 31 is;

when the inner shell 3 is completely embedded in the bridge frame body 1, the lower part of the second bottom plate 33 is provided with support bars 34, the support bars 34 are elastic pieces, gaps are reserved among the support bars 34, the upper end of the bridge frame body 1 is provided with a turnover plate 13, the turnover plate 13 is connected in the turnover extending edges 31 in a sliding manner, and the turnover plate 13 and the turnover extending edges 31 are matched with the sliding groove 21 in a sliding manner after being embedded, so that the cable pressure borne by the inner shell 3 can be effectively distributed on the bottom plate and the side plates of the bridge frame body 1, the stress concentration is avoided, the service life of the bridge frame is prolonged, and the deformation of the bridge frame is avoided;
