[0036] The present utility model provides a convenient opening and closing type cable tray.

[0037] Before the detailed introduction, it is necessary to understand the application scenarios of the present utility model. Cable trays are often laid in different environments and often need to pass through complex working environments, such as high-temperature, high-humidity, dusty, and oily areas. Therefore, if a cable outlet failure occurs, the maintenance difficulty will increase during maintenance. Especially in enclosed spaces such as basements and tunnels, the light is usually dim, and it is inconvenient to open the cable tray, which is not conducive to the inspection and maintenance of cables. The convenient opening and closing type cable tray facilitates the inspection and repair of cables by staff.

[0038] The following further elaborates the present utility model in detail in conjunction with the drawings and specific embodiments.

[0039] As Figures 1-3 shown, it is the overall structural schematic diagram of the present utility model:

[0040] A convenient opening and closing type cable tray includes

[0041] The bridge main body 1 has two symmetrical side plates 13 and a bottom plate 3. The bridge main body 1 has an open semi-enclosed structure and extends along a first direction, which is the horizontal longitudinal direction; the fixing seat 14 is arranged on the two side plates 13 and has a rotating hole; the bridge cover 6 extends along the first direction, and the width of the bridge cover 6 is adapted to the opening of the bridge main body 1; the circular protrusions 15 are symmetrically arranged on both sides of the bridge cover 6, and the circular protrusions 15 are sleeved in the rotating holes of the fixing seats 14 and are hinged to the fixing seats 14 to form a hinge axis perpendicular to the first direction.

[0042] As a kind of trough cable bridge, the bridge main body 1 is a trough component formed by bending, stamping a whole steel plate or integrally casting, generally having an open semi-enclosed U shape. The trough cable bridge has a certain depth and sealing property. It is most suitable for laying computer cables, communication cables, thermocouple cables and other control cables of high-sensitivity systems. It has good effects on shielding interference of control cables and protecting cables in severely corrosive environments.

[0043] Generally speaking, the width of the bridge cover 6 is adapted to the opening of the bridge main body 1 and can be covered on the bridge main body 1. The connection method between the bridge cover 6 and the bridge main body 1 is generally ordinary covering, but there are problems such as being inconvenient to open or being prone to covering deviation. Therefore, a convenient opening and closing method proposed by the present utility model is that the bridge cover 6 is hinged to the bridge main body 1, and the hinge axis is perpendicular to the first direction. At this time, the circular protrusions 15 are sleeved in the rotating holes of the fixing seats 14, which not only plays a rotating role but also plays a role in fixedly supporting the two side plates 13 to prevent the two side plates 13 from deforming towards each other. If the hinge axis is arranged parallel to the side plates 13, although hinging can be achieved, it is not easy to cover when problems such as deformation of the bridge main body 1 occur later.

[0044] Furthermore, a connecting rod mechanism is provided, including: the connecting rod seats 5, which are symmetrically arranged at the tops of the two side plates 13. The connecting rod seats 5 have a through hole; the hinge rod 10 passes through the through hole of the connecting rod seat 5 and is rotatably connected to the connecting rod seat 5 and has a rotating shaft; one end of the first connecting rod 8 is fixedly connected to the hinge rod 10, and the other end rotates around the rotating shaft; one end of the second connecting rod 9 is hinged to the first connecting rod 8, and the other end is hinged to the bridge cover 6; the rotating part 11 is fixedly connected to one end of the hinge rod 10.

[0045] During use, maintenance personnel can easily open and close the bridge cover 6 by operating the rotating part 11. The specific operation steps are as follows: Hold and twist the rotating part 11, and the rotating part 11 drives the articulated rod 10 to rotate; the articulated rod 10 drives the first connecting rod 8 to move; the first connecting rod 8 transmits power to the second connecting rod 9, causing the bridge cover 6 to rotate around the hinge axis; when the first connecting rod 8 and the second connecting rod 9 rotate into a collinear state, the bridge cover 6 reaches the maximum opening and closing angle, restricting further opening and closing of the bridge cover 6 and protecting the overall structure from damage. If you want to close the bridge cover 6, the user only needs to further operate the rotating part 11 and repeat the above steps.

[0046] Furthermore, both the first connecting rod 8 and the second connecting rod 9 are two, symmetrically arranged on the two side plates 13. If only one first connecting rod 8 and one second connecting rod 9 are provided, the opening and closing can be achieved. The first connecting rod 8 is most stable when specifically arranged at the middle position of the articulated rod 10. If considering the stability of the plane, the first connecting rod 8 and the second connecting rod 9 can also be further arranged into two, symmetrically arranged based on the vertical symmetry axis of the bridge cover 6.

[0047] It should be noted that the setting of the partition 2 not only enhances the structural strength of the bridge body 1, but also makes the spatial layout inside the bridge more reasonable, facilitating wiring and maintenance. When cables enter the bridge, there are often various cables of different specifications and models. Especially when some cables are connected to special voltages and need to be independently separated from other cables, an independent space needs to be set up. For this reason, a partition 2 is proposed to divide the bridge body 1 into different independent spaces.

[0048] Furthermore, through the cooperation of the card slot 16 and the partition 2, the partition 2 is set to be detachable. In this way, the number of partitions 2 required can be installed according to different needs to separate different cable laying cavities.

[0049] It is worth noting that as Figure 4 shown, the card slot 16 is a U-shaped groove, which has an S-shaped arc inner side and an arc-shaped outer side. The U-shaped structure of the card slot 16 can effectively improve its ability to accommodate and fix objects. The S-shaped arc inner side makes the card slot 16 have a clamping effect when fixing objects, so it is more stable. Specifically, the S-shaped arc inner side is composed of two opposite arc segments, and the transition between the arc segments is smooth, making the entire inner side present an S-shaped curve. This design is not only beautiful, but also makes the card slot 16 have a larger inlet, making it easier to insert the partition 2 during actual use and facilitating the operation.

[0050] It should be pointed out that the limit slot 4 is fixed on the side plate 13, and its shape is strip-shaped, and the size is designed according to the diameter and quantity of special cables to ensure that the cables can be smoothly accommodated. The cables can be independently arranged in the limit slot 4.

[0051] In addition, the addition of the crossbeam 12 and the cylindrical protrusion 7 further strengthens the structure of the bridge cover 6, ensuring the stability of the bridge cover 6 during the opening and closing process, and also providing a good rotation fulcrum for the second connecting rod 9.

[0052] In summary, through the specific description of the above embodiments, the convenient opening and closing bridge of the present utility model demonstrates the novelty and practicality of its structural design. This bridge is not only easy to install and maintain, but also has a solid structure, high load-bearing capacity and good performance, meeting the needs of cable laying and protection in various scenarios.

[0053] It should be noted that the above embodiments are only specific implementation manners of the present utility model and are not limited to the described embodiments. For those of ordinary skill in the art, without departing from the spirit and scope of the technical solution of the present invention, various changes and modifications can be made, and these should all be included within the protection scope of the present utility model.

[0054] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
