Description

Technical Field

[0001] The utility model relates to the technical field of wire troughs, in particular to a reinforced low-smoke zero-halogen wire trough cover plate. Background Art

[0002] Cable troughs are also called wiring troughs, wiring troughs, and cable troughs. They are used to organize power cables, data cables, and other wires in a standardized manner and are fixed to electrical tools on the wall or ceiling. Cable troughs usually include a trough body and a trough cover. The trough body consists of a bottom plate and side plates on both sides, and one side of the side plate is connected to the bottom plate.

[0003] A reinforced low-smoke halogen-free wire trough cover currently in use has been found through searching, for example, in a Chinese patent document with an authorization publication number of CN210404595U, which discloses a reinforced low-smoke halogen-free wire trough cover, comprising a trough cover and a disassembly and installation mechanism, the disassembly and installation mechanism being located on the trough cover, the disassembly and installation mechanism comprising a first limit block and a second limit block, both of which are fixed to the bottom of the trough cover, a through hole being provided in the middle of the trough cover, a fixing groove being reserved on the side of the through hole, the bottom of the side of the control rod being connected to the end of the limit rod through a traction line, and a control block being connected to the upper end of the control rod, and a trough body being arranged below the trough cover; the utility model rotates the control block so that the two limit rods can be separated or engaged with the two limit grooves at the same time, thereby facilitating the disassembly and installation of the trough cover and the trough body, and avoiding the need to remove the trough body and trough cover of a certain trough when multiple wiring troughs are connected together for use, thereby facilitating the construction of workers and improving work efficiency.

[0004] Although the above patents solve the problems in the above-mentioned background technology, they still have the following shortcomings: 1. The traction wire is used in the wire trough to achieve the separation of the limit rod and the limit groove. Therefore, when used for a long time, the traction wire is easily worn or broken, which brings trouble to the subsequent disassembly of the cover plate; 2. The sealing effect between the wire trough and the cover plate is not good, which easily causes dust to enter the wire trough through the gap of the cover plate, thereby reducing the dustproof effect of the wire trough, which is not conducive to the subsequent heat dissipation of the wire.

[0005] In summary, the utility model solves the problems in the above-mentioned background technology by designing a reinforced low-smoke zero-halogen wire duct cover. Utility Model Content

[0027] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0028] A reinforced low-smoke zero-halogen wire duct cover plate, comprising a wire duct body 1 and a cover plate 2 arranged on the top of the wire duct body 1, a mounting groove 101 is provided on the top surface of the wire duct body 1, a stretch spring 1011 is fixedly installed on the inner bottom end of the mounting groove 101, a sealing horizontal strip 1012 is fixedly installed on the top of the stretch spring 1011, a sealing block 201 is fixedly installed on the bottom surface of the cover plate 2, and a mounting mechanism 3 is provided between the cover plate 2 and the wire duct body 1;

[0029] Specifically, the extension springs 1011 are equidistantly distributed frontward and rearward about the bottom surface of the installation groove 101, the outer surface of the sealing bar 1012 is in sliding sealing contact with the inner wall of the installation groove 101, and the sealing block 201 is arranged correspondingly to the installation groove 101;

[0030] In this embodiment, the extension spring 1011 is mainly used to support the sealing cross bar 1012, so that the sealing cross bar 1012 and the mounting groove 101 are in sliding contact, and the sealing block 201 is mainly provided to facilitate the formation of a sealing and fitting contact with the sealing cross bar 1012, thereby achieving a sealing contact between the cover plate 2 and the wire groove body 1, thereby improving the sealing performance of the wire groove.

[0031] It should be noted that the wire trough body 1 and the cover plate 2 are both made of halogen-free hard material, and the top surface of the cover plate 2 is flush with the top surface of the wire trough body 1 .

[0032] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The mounting mechanism 3 includes a plug hole 301, a mounting cavity 302 and a sliding groove 303. The plug hole 301 is provided on the left and right sides of the inner wall of the slot body 1, and the mounting cavity 302 is provided on the left and right ends of the cover plate 2. A guide column 304 is fixedly installed inside the plug hole 301, and a guide spring 305 and a plug block 306 are respectively sleeved on the outer side of the guide column 304. A toggle block 307 is fixedly installed on the top surface of the plug block 306, and the sliding groove 303 is provided on the top surface of the cover plate 2;

[0033] Specifically, the guide column 304 is symmetrically distributed about the inner central axis of the cover plate 2, the left end of the plug-in block 306 fits through the inner wall of the installation cavity 302 and extends to the left side of the cover plate 2, and is plugged and matched with the plug-in hole 301, and the toggle block 307 extends to the top surface of the cover plate 2 through the sliding groove 303;

[0034] In the present embodiment, the setting of the toggle block 307 is mainly used to drive the plug-in block 306, so that the plug-in block 306 slides along the outer surface of the guide column 304 and squeezes the guide spring 305, thereby realizing the separation of the plug-in block 306 from the plug-in hole 301. In the absence of external force, the compressed guide spring 305 will gradually stretch and drive the plug-in block 306, so that the plug-in block 306 fits with the plug-in hole 301, thereby achieving the effect of quickly installing the cover plate 2 and meeting the use needs of the staff.

[0035] The working process of the utility model is as follows: when using a reinforced low-smoke zero-halogen wire duct cover, first place the wire duct body 1 at the desired position, then install the cover 2, move the cover 2, and make the sealing block 201 gradually close to the installation groove 101. When the sealing block 201 contacts the sealing cross bar 1012, the sealing cross bar 1012 will move downward under the action of force and squeeze the extension spring 1011. The extension spring 1011 will generate an elastic force during the contraction process, and the elastic force can ensure that the sealing cross bar 1012 forms a sealing contact with the sealing block 201, thereby The sealing effect of the wire trough is improved. At the same time, under the action of the guide spring 305, the plug-in block 306 gradually moves along the outer surface of the guide column 304 and forms a plug-in fit with the plug-in hole 301, thereby completing the installation operation of the cover 2. Further, when the cover 2 needs to be disassembled, an external force is applied to the toggle block 307, so that the toggle block 307 drives the plug-in block 306 to move along the outer surface of the guide column 304 and gradually separate from the plug-in hole 301, thereby realizing the disassembly operation of the cover 2, providing convenience for the staff and meeting the staff's usage needs.
