Specific implementation mode
[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] As Figure 1 、 Figure 2 shown, a connection structure of a cable bridge section of the present utility model includes a connecting mechanism 3 arranged between the butt-jointed first bridge section body 1 and the second bridge section body 2. A gap 4 for heat expansion and elongation and yielding is provided between the first bridge section body 1 and the second bridge section body 2. The connecting mechanism 3 is symmetrically arranged on both outer sides of the first bridge section body 1, and includes a connecting rod 31 and a connecting pin 32. The connecting pin 32 is slidably connected to the first bridge section body 1 along the width direction of the first bridge section body 1. One end of the connecting rod 31 is slidably connected to the connecting pin 32 along the length direction of the first bridge section body 1. The other end of the connecting rod 31 is provided with an insertion part 311 extending towards the inside of the first bridge section body 1. The insertion part 311 is inserted into the jack 21 provided on the second bridge section body 2, so that the first bridge section body 1 and the second bridge section body 2 are butt-connected. A return spring 33 is provided on the connecting pin 32, with one end connected to the connecting rod 31 to make the connecting rod 31 slide away from the first bridge section body 1. A locking spring 34 is provided between the connecting pin 32 and the first bridge section body 1 to make the connecting pin 32 slide into the first bridge section body 1 along the width direction of the first bridge section body 1, so that the insertion part 311 is inserted into the jack 21 on the second bridge section body 2.
[0023] The connection structure of the cable tray section of the present utility model can first install the connection mechanism 3 on the first tray section body 1. When installing the cable tray, only need to compress the locking spring 34 and move the connection pin 32 outward along the width direction of the first tray section body 1, then the connecting rod 31 can be moved outward, so that the insertion part 311 at one end of the connecting rod 31 can be inserted into the jack 21 on the second tray section body 2. The installation and docking of the cable tray section are more convenient and the efficiency is higher. The locking spring 34 makes the connection pin 32 slide into the first tray section body 1, so that the insertion part 311 is inserted into the jack 21 on the second tray section body 2, ensuring that the two are always in an inserted and matched state. The connection structure of the cable tray section of the present utility model is symmetrically provided with a connecting rod 31 and a connection pin 32 on both sides of the first tray section body 1. The first tray section body 1 is inserted into the jack 21 on the second tray section body 2 through the insertion part 311 extending in the inner direction of the first tray section body 1 at one end of the connecting rod 31, so as to realize the docking connection with the second tray section body 2. The connecting rods 31 on both sides can limit the position of the second tray section body 2 in all directions, ensuring the stable connection between the two. Due to the present utility model having a gap 4 for heat expansion elongation and yielding between the first tray section body 1 and the second tray section body 2, when the first tray section body 1 and the second tray section body 2 expand and elongate due to heat, they can elongate by compressing the return spring 33, thereby preventing the spliced cable tray from deforming. When the first tray section body 1 and the second tray section body 2 contract due to cold, they can move away from each other under the action of the return spring 33 to restore the gap, so as to be deformed when heated.
[0024] In order to better protect the cable, the present utility model also provides a channel-shaped member 5 between the first tray section body 1 and the second tray section body 2 for blocking the gap 4. The channel-shaped member 5 can be directly placed at the gap 4 between the first tray section body 1 and the second tray section body 2. In the embodiment of the present utility model, in order to prevent the channel-shaped member 5 from being displaced due to the thermal expansion and contraction deformation of the first tray section body 1 and the second tray section body 2, one end of the channel-shaped member 5 is connected to the first tray section body 1 through a pin 6, and the other end is inserted into the second tray section body 2. One end of the channel-shaped member 5 is connected to the first tray section body 1 through a pin 6, making the installation of the channel-shaped member 5 convenient. In addition, the channel-shaped member can also play a longitudinal (width direction of the first tray section body) limiting role on the second tray section body 2, which can further improve the connection stability between the first tray section body 1 and the second tray section body 2.
[0025] As Figure 3As shown in the figure, the utility model also provides a bridge section for the above-mentioned connection structure of a cable tray section, which includes a bridge section body 7. On both outer sides of one end of the bridge section body 7, connection mechanisms 3 are symmetrically arranged. The connection mechanism 3 includes a connecting rod 31 and a connecting pin 32. The connecting pin 32 is slidably connected to the bridge section body 7 along the width direction of the bridge section body 7. One end of the connecting rod 31 is slidably connected to the connecting pin 32 along the length direction of the bridge section body 7. The other end of the connecting rod 31 is provided with a plug-in portion 311 extending towards the inside of the bridge section body 7. A return spring 33 is arranged on the connecting pin 32, one end of which is connected to the connecting rod 31 to make the connecting rod 31 slide away from the first bridge section body 1. A locking spring 34 is arranged between the connecting pin 32 and the first bridge section body 1 to make the connecting pin 32 slide into the first bridge section body 1 along the width direction of the first bridge section body 1. On both sides of the other end of the bridge section body 7, there are jacks 21 for cooperating with the plug-in portions 311 of another bridge section.
[0026] When the bridge sections of the utility model are splicing the cable tray, as Figure 1 shown, it only needs to make the connection mechanism setting end of the first bridge section body 1 and the jack setting end of the second bridge section body of the two butt-jointed bridge sections face each other. Then, compress the locking spring 34 and move the connecting pin 32 outward along the width direction of the first bridge section body 1, so that the connecting rod 31 can move outward. Thus, the plug-in portion 311 at one end of the connecting rod 31 can be inserted into the jack 21 on the second bridge section body 2. The splicing connection of the cable tray is more convenient and has higher efficiency. The locking spring 34 can make the connecting pin 32 slide into the first bridge section body 1, so that the plug-in portion 311 is inserted into the jack 21 on the second bridge section body 2, ensuring that the two are always in a plug-in cooperation state. When the first bridge section body 1 and the second bridge section body 2 contract due to cold, they can move away from each other under the action of compressing the return spring 33 to restore the gap.
[0027] In order to better protect the cable, a channel-shaped member 5 for blocking the gap 4 is arranged at one end of the bridge section body 7. One end of the channel-shaped member 5 is connected to the first bridge section body 1 through a plug pin 6, and the other end is in plug-in cooperation with one end of another bridge section.
[0028] In order to facilitate the heat dissipation of the cable, heat dissipation holes (not shown in the figure) are also arranged at the bottom of the bridge section body 7.
