Abstract

This utility model discloses a cable tray with an anti-fall-off cover plate locking mechanism, comprising U-shaped inner strips welded to the left and right sides of the inner cavity of the cable tray. Both U-shaped inner strips are located at the bottom of the inner cavity of the cable tray. Raised strips are welded to the left and right sides of the inner cavity of each U-shaped inner strip. A cover plate is provided at the bottom of the cable tray. Hollow rectangular strips are welded to the left and right sides of the top of the cover plate. Grooves are formed on the left and right sides of each hollow rectangular strip. This utility model allows the hollow rectangular strips to slide into the inner cavity of the U-shaped inner strips by sliding or pushing the cover plate upwards. The hollow rectangular strips are then embedded into the inner cavity of the U-shaped inner strips. Self-tapping screws are then tightened between the cover plate and the cable tray, thereby fixing the cover plate and the cable tray together. This achieves a tighter connection between the cover plate and the cable tray, making the connection more secure.

Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, and in particular relates to cable trays with anti-fall-off cover plates for locking. Background Technology

[0002] Cable trays are widely used in electrical wiring systems in construction, industry, energy and other fields. They arrange cables in an orderly manner through standardized trough, tray or ladder structures, which facilitates installation, maintenance and future expansion.

[0003] In cable tray systems, the cover plate is an important component, its function being to close the opening of the main body of the cable tray and enhance the protection of the internal cables. The cover plate is located at the bottom of the cable tray. Due to the weight of the cables themselves and long-term use, the cover plate may loosen from the cable tray, or even detach from it. To address this, an anti-detachment cover plate locking cable tray design was created. This design adds a limiting component to the original cable tray and cover plate, which can make the connection between the cover plate and the cable tray tighter through an "embedded" method. In addition, the use of self-tapping screws and tensile edging further secures the connection between the cover plate and the cable tray. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray with an anti-fall-off cover plate that locks the cable tray, thereby making the connection between the cover plate and the cable tray tighter and more secure, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cable tray with an anti-fall-off cover plate is used to lock the cable tray, comprising U-shaped inner strips welded to the left and right sides of the inner cavity of the cable tray; both U-shaped inner strips are located at the bottom of the inner cavity of the cable tray; protruding strips are welded to the left and right sides of the inner cavity of the U-shaped inner strips; a cover plate is provided at the bottom of the cable tray; hollow rectangular strips are welded to the left and right sides of the top of the cover plate; grooves are provided on the left and right sides of the hollow rectangular strips; a round hole is provided on the surface of the cover plate; a self-tapping screw is threaded into the inner cavity of the round hole; and the cover plate is fixedly connected to the bottom of the cable tray by the self-tapping screw.

[0006] Preferably, the surface of the hollow rectangular strip is slidably connected to the inner cavity of the U-shaped inner liner, and the inner cavity of the groove is slidably connected to the surface of the convex strip.

[0007] Preferably, the inner cavity of the cable tray is slidably connected to a tension edging, and the inner cavity of the tension edging is slidably connected to the surface of the U-shaped inner lining strip.

[0008] Preferably, both the tensile edging and the surface of the cover plate are provided with screw holes, and screws are threaded into the inner cavity of the screw holes.

[0009] Preferably, the cable tray and the U-shaped inner liner are both fixedly connected to an edge plate, and a limiting groove is provided at the top of the U-shaped inner liner.

[0010] Preferably, a limiting strip is welded to the top of the tension-sealing inner cavity, and the surface of the limiting strip is slidably connected to the inner cavity of the limiting groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model allows the hollow rectangular strip to slide into the inner cavity of the U-shaped inner liner by sliding or pushing the cover plate upwards. Then, the hollow rectangular strip is embedded into the inner cavity of the U-shaped inner liner. Next, the self-tapping screws are screwed into the cover plate and the cable tray, thereby fixing the cover plate and the cable tray. This achieves a tighter connection between the cover plate and the cable tray, making the connection between the cover plate and the cable tray more secure.

[0013] 2. By using the limiting groove and the limiting strip together, this utility model can keep the tension edge straight after it slides into the inner cavity of the cable tray, thus preventing the tension edge from becoming skewed in the inner cavity of the cable tray.

[0023] Working principle: When using this utility model, the user fixes the cable tray 1 to the building wall, then slides or pushes the cover plate 4 upwards, causing the hollow rectangular strip 5 to slide into the inner cavity of the U-shaped inner lining strip 2, thus embedding the hollow rectangular strip 5 into the inner cavity of the U-shaped inner lining strip 2. This allows the cover plate 4 and the cable tray 1 to achieve an initial fixed connection. Then, the self-tapping screw 7 is screwed between the cover plate 4 and the cable tray 1, thereby fixing the cover plate 4 and the cable tray 1 together. This makes the connection between the cover plate 4 and the cable tray 1 tighter and more secure.

[0024] In summary: This anti-fall-off cover locks the cable tray by sliding or pushing the cover 4 upwards, causing the hollow rectangular strip 5 to slide into the inner cavity of the U-shaped inner liner 2, thus embedding the hollow rectangular strip 5 into the inner cavity of the U-shaped inner liner 2. Then, the self-tapping screw 7 is screwed between the cover 4 and the cable tray 1, thereby fixing the cover 4 and the cable tray 1. This achieves a tighter connection between the cover 4 and the cable tray 1, making the connection between the cover 4 and the cable tray 1 more secure.
