Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a plastic-sprayed bridge. Background Art

[0002] Cable trays are divided into trough-type cable trays, tray-type cable trays, plastic-sprayed cable trays, ladder-type cable trays, grid-type cable trays and other structures, and are composed of brackets, brackets and installation accessories. They can be erected independently or laid on various buildings and pipe gallery brackets, and have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance.

[0003] The existing bridge frame includes a bridge frame body, a cover plate arranged on the bridge frame body, and multiple sets of bolts and nuts fastening the bridge frame body and the cover plate. Since the bridge frame is long and narrow, multiple sets of bolts and nuts need to be arranged along the length direction of the bridge frame to ensure that the cover plate is stably placed above the bridge frame body. In addition, the bolt and nut structure requires bidirectional tightening operation, so it is also necessary to specially open an operation port on the bridge frame body for tightening operation; in addition, the tightening operation method of the bolt and nut requires multiple rotations, which results in a large workload and high production cost for this fixing method, which affects the later maintenance and reduces the market competitiveness of the product. Utility Model Content

[0004] The utility model aims to provide a plastic-sprayed bridge frame, which is easy to operate and has low production cost, thereby ensuring the convenience of later maintenance and greatly increasing the market competitiveness of the product.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a spray-coated bridge frame, comprising: a bridge frame body, which is configured to have an opening structure at both ends and one side for placing cables; a cover plate, which is configured to cover the opening on one side of the bridge frame body; a plurality of plastic fasteners, which are configured to be integrally connected to the bridge frame body; a deformation gap, which is configured to cooperate with the plastic fastener to cause it to undergo plastic deformation so as to buckle and fix the cover plate to the bridge frame body; a limiting structure, which is arranged between the cover plate and the plastic fastener to limit the relative movement of the two along the length direction of the bridge frame body.

[0006] By adopting the above technical solution, the cover plate is set above the opening on one side of the bridge body, and then the plastic fastener is bent to cause plastic deformation to fasten the cover plate to the bridge body, and the limit structure is used to limit the relative movement of the two along the length direction of the bridge, so as to achieve the fixation of the cover plate on the bridge body. This fixing method is easy to operate and has low production cost, and the cover plate and the bridge body can be conveniently separated by bending the plastic fastener in the later stage, so as to ensure the convenience of later maintenance and greatly increase the market competitiveness of the product.

[0007] It is further configured that: the plastic fasteners are arranged on both sides of an opening on one side of the bridge body, the deformation gap is formed between the bridge body and the plastic fasteners, and the plastic fasteners are formed into a long strip that reciprocates and deforms toward the opening on one side of the bridge body.

[0008] By adopting the above technical solution, this setting structure can form plastic fasteners by stamping, which is convenient for processing and further reduces the processing cost; and the plastic fasteners of this structure can have a larger plastic deformation amount, thereby ensuring the stability of the fastening.

[0009] It is further configured as follows: a first bending section is formed between the bridge frame body and the plastic fastener, and the first bending section forms an insertion gap between the plastic fastener and the two outer side walls of the bridge frame body for the cover plate to be inserted, and when the cover plate is covered on one side opening of the bridge frame body, the two edges of the cover plate extend and are placed on the outside of the two side walls of the bridge frame body and inserted into the insertion gap.

[0010] By adopting the above technical solution, the first bent section is used to form an insertion gap, thereby ensuring the precise assembly of the cover plate and the bridge body, avoiding structural interference and causing assembly precision.

[0011] It is further configured as follows: the limiting structure includes a plastic limiting section formed on the plastic fastener and a limiting hole formed on the cover plate, and when the plastic fastener is fastened to the cover plate, the limiting hole corresponds to the plastic limiting section and the plastic limiting section can be bent into the limiting hole.

[0012] By adopting the above technical solution, after the plastic fastener is fastened and fixed to the cover plate, the plastic limit segment is bent to be embedded in the limit buckle, thereby constituting the limit between the cover plate and the bridge body to ensure the stability of the assembly. This setting structure can form the plastic limit segment by stamping, which is convenient to process and has lower production cost.

[0013] It is further configured that: when the plastic fastener is fastened to the cover plate, the plastic limiting section is located outside the two side walls of the bridge body.

[0014] By adopting the above technical solution, this setting method enables the formation of the limit hole on the side wall of the bridge frame after installation, thereby reducing the probability of external dust and rainwater entering the interior of the bridge frame body, thereby providing better protection for the internal cables.

[0015] It is further configured as follows: a protective layer is provided outside the bridge frame body and the cover plate.

[0016] By adopting the above technical solution, the provision of the protective layer can protect the bridge frame and extend the service life of the bridge frame.

[0017] It is further configured that: when the plastic fastener is fastened to the cover plate, the free end of the plastic fastener is provided with a warped edge section warped away from the side of the cover plate.

[0018] By adopting the above technical solution, the setting of the warped edge section forms a force-bearing end, so that the plastic fasteners can be disassembled more conveniently to separate the cover plate and the bridge body, making the operation more convenient.

[0019] In summary, the utility model has the following beneficial effects: the utility model is easy to operate and has low production cost, thereby ensuring the convenience of later maintenance and greatly increasing the market competitiveness of the product. BRIEF DESCRIPTION OF THE DRAWINGS
