Tray type bridge stand capable of being spliced

Abstract

The invention provides a tray type bridge stand capable of being spliced. The tray type bridge stand comprises a body seat, four groups of screw holes, second connecting seats, a first connecting seat, a baffle plate and a single body stand, wherein ventilation holes are formed in the bottom of the body seat; the four groups of screw holes are formed in the periphery of the body seat; the second connecting seats are fixedly arranged on two sides of the body seat with screws; the first connecting seat is fixedly arranged on the right side of the body seat with screws; the baffle plate is fixedly arranged on the left side of the body seat with screws; the single body stand is connected onto the second connecting seats with fastening screws; a single body seat comprises a base plate and sideplates, ventilation holes are formed in the bottom of the base plate, the side plates are arranged on the side faces of the base plate, second connection ports are formed in two sides of the side plates, and reinforcing ribs are arranged on the outer sides of the middle parts of the side plates. The tray type bridge stand capable of being spliced provided by the invention is simple in structure, and the stability of the bridge stand is strengthened through the structures of the reinforcing ribs arranged on the side faces of the side plates; the corrosion resistance of the bridge stand is higher through electroplated zinc and hot-dip zinc sprayed on the surfaces of the connecting seats and the surface of the single body stand; and through splicing, the three-way and four-way functions can be realized, and the universal performance is good.

Description

technical field [0001] The invention relates to a tray type bridge, in particular to a splicable tray type bridge. Background technique [0002] The bridge is an essential device for cable installation. The existing tray-type bridge includes two side plates and a bottom plate arranged between the two side plates. The bottom plate is a load-bearing part for placing cables. In the prior art, the load-bearing capacity of the tray-type bridge is not very strong, and the bending resistance is relatively weak, especially the expenditure on the manufacturing cost is relatively large; therefore, technical progress and structural improvement are needed to make the cable bridge more durable It is durable and reduces its manufacturing cost; when it comes to the collection and change of cables, it is necessary to use a three-way bridge, but the design of the three-way connection parts of the three-way connection on the market is mostly right-angled, and this structure is in the laying ...

Problems solved by technology

In the prior art, the load-bearing capacity of the tray-type bridge is not very strong, and the bending resistance is relatively weak, especially the expenditure on the manufacturing cost is relatively large; therefore, technical progress and structural improvement are needed to make the cable bridge more durable It is durable and reduces its manufacturing cost; when it comes to the collection and change of cables, it is necessary to use a three-way bridge, but the design of the three-way connection parts of the three-way connection on the market is mostly right-angled, and this structure is in the laying When the cables need to be collected and changed, the cables will be bent at 90 degrees, which will easily cause the wires inside the cables to break, and the regular friction of the edges and corners of the right-angled surfaces will accelerate the wear and aging of the cables, making the cables unable to reach the theoretical service life. , to a certain extent increases the expenditure of cable laying, and there is also a great hidden danger in safety
