Description

Technical Field

[0001] The utility model belongs to the technical field of cable bridge wiring, and particularly relates to a special combined anti-dropping device for a trough box type cable bridge. Background Art

[0002] Trough-box cable trays are often used for cable wiring. The tray cover is often fixed with discrete 7-shaped locks. A pair of cover fasteners of this style are arranged on both sides of the tray. Pressure is applied to the tray cover through the screw heads to fix the tray cover to prevent it from falling off. However, the following disadvantages still exist to a certain extent.

[0003] The locking screw head applies pressure to the bridge cover over a small area but with great pressure, which can easily damage the cover. The screw gasket applies pressure to the bridge cover for vertical fixation. In the direction parallel to the bridge cover, the nail head is only fixed by the friction between the gasket below and the bridge cover. The fixing ability is insufficient and it is easy to fall off when encountering equipment vibration, external collision, etc., causing the bridge cover to warp, loosen or even fall, making the cable lose protection. In serious cases, it will injure people and affect equipment and personal safety.

[0004] In order to solve the above technical problems, we have designed a special combined anti-slip device for trough-box type cable tray. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] As a preferred embodiment of the present invention, Figure 1-Figure 2 As shown, this embodiment provides a special combined anti-slip device for a trough-box type cable tray, including an installation component 1. The number of the installation components 1 is two and they are symmetrically arranged on the left and right. The installation component 1 includes a locking body frame 11. A holding component 2 is arranged on the top between the opposite sides of the locking body frame 11.

[0022] In some embodiments, Figure 1 As shown, a fastening screw 12 is threadedly provided through the top of the lock body frame 11, and a circular plate is integrally formed on the top of the fastening screw 12.

[0023] In order to facilitate the staff to rotate the fastening screw 12 in this embodiment, the fastening screw 12 can be connected with the fastening nut 3 under the action of the thread, thereby driving the combined pressure strip 21 to press down the bridge frame.

[0024] In some embodiments, Figure 1 and Figure 2 As shown, a threaded hole for use with a fastening screw 12 is provided on the top of the lock body frame 11, and the lock body frame 11 is in a "7"-shaped structure.

[0025] In order to make the bridge stable inside the two locking main frames 11 without deviation, the contact area between the fixing screw and the bridge cover is increased, the pressure is reduced, and the risk of damage to the bridge cover is reduced.

[0026] In some embodiments, Figure 2 As shown, the pressing assembly 2 includes a combined pressure strip 21, which is arranged at the top between the opposite sides of the lock body frame 11, and the left and right sides of the top of the combined pressure strip 21 are fixedly welded with fastening nuts 3.

[0027] The combined pressure strip 21 in this embodiment is used as a connecting piece for the locking main frame 11 on both sides, providing locking force to the locking main frame 11 while enhancing the anti-collision ability. For bridge frames of different widths, pressure strips of different lengths can be selected for adaptation to enhance the versatility of the anti-slip device.

[0028] In some embodiments, Figure 2 As shown, a mounting groove 14 is formed through the bottom of one side of the lock body frame 11 , and an anti-drop buckle 13 is integrally formed on the opposite side of the bottom of the inner cavity of the mounting groove 14 .

[0029] When in use, the paired locking body frames 11 are placed on both sides of the bridge frame respectively, so that the bottom of the bridge frame is stuck above the anti-drop buckle 13, and then the combined pressure strip 21 is placed above the bridge frame and directly below the locking body frame 11, and the fastening screw 12 is rotated. Under the action of the thread, the bottom of the pressure strip 21 extends into the inner cavity of the fastening nut 3 and is threadedly connected to the inner wall thereof, thereby driving the combined pressure strip 21 to descend, so that the bottom of the pressure strip 21 is tightly attached to the top of the bridge frame, thereby achieving a stable anti-drop effect.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
