A connecting slide plate is slidably installed on the inner wall of the sliding groove. One end of the connecting slide plate passes through the sliding opening on the main board of the bridge tray and extends to the front side of the main board of the bridge tray and is fixedly installed with a limiting movable plate. The connecting slide plate is slidably installed in the sliding opening on the main board of the bridge tray.

[0011] Preferably, the bridge main board has an opening for connecting the sliding plate.

[0012] Preferably, the bridge tray motherboard has mounting holes, which facilitates the installation of the bridge tray motherboard.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This weld-free ladder-type cable tray, through the setting of the limiting movable rod, can limit the support plate and the support slide plate, which facilitates the adjustment of the distance between the two sets of cable tray main boards. In addition, the space between the two sets of cable tray main boards can be adjusted according to the number of cables, which is convenient for supporting different numbers of cables, thereby improving the practicality of the device. Furthermore, through the setting of the bridge plate and the connecting slide plate, the number of bridge plates and connecting slide plates can be increased or decreased through the openings and sliding openings on the cable tray main board when supporting the cables. This allows the number of bridge plates and connecting slide plates to be adjusted according to the weight of the cables, increasing the overall support effect of the device, reducing the deformation of the device during use, and extending the service life of the device.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a weld-free ladder-type cable tray, including a cable tray main board 1, a support slide plate 3 and a bridge plate 7. The cable tray main board 1 has a sliding opening; the cable tray main board 1 is provided with a support plate 2 and a support slide plate 3, and a limiting movable rod 6 is used to limit the support plate 2 and the support slide plate 3; the bridge plate 7 is provided with a connecting slide plate 8, and the number of connecting slide plates 8 is two sets.

[0021] Furthermore, there are two sets of cable tray mainboards 1. One set of cable tray mainboards 1 has a support plate 2 fixedly installed on the front side, and the other set of cable tray mainboards 1 has a support slide plate 3 fixedly installed on the rear side. The support plate 2 has a groove inside that allows the support slide plate 3 to move, and the rear side of the support slide plate 3 extends into the groove of the support plate 2.

[0022] Furthermore, a limit spring 4 is fixedly installed at the bottom of the support plate 2, a pull plate 5 is fixedly installed at the bottom of the limit spring 4, and a limit rod 6 is fixedly installed at the top of the pull plate 5. The support plate 2 has a hole for the limit rod 6 to move, and the support slide plate 3 has a limiting hole for the limit rod 6 to move. One end of the limit rod 6 passes through the hole on the support plate 2 and extends into the limiting hole on the support slide plate 3. This arrangement can limit the support plate 2 and the support slide plate 3, which facilitates the adjustment of the distance between the two sets of cable tray main boards 1. In addition, the space between the two sets of cable tray main boards 1 can be adjusted according to the number of cables, which is convenient for supporting different numbers of cables, thereby improving the practicality of the device.

[0023] Furthermore, the cable tray main board 1 is provided with a bridge plate 7. The front and rear sides of the bridge plate 7 are provided with sliding grooves. A connecting slide plate 8 is slidably installed on the inner wall of the sliding groove. One end of the connecting slide plate 8 passes through the sliding opening on the cable tray main board 1 and extends to the front side of the cable tray main board 1, where a limit movable plate 9 is fixedly installed. The connecting slide plate 8 is slidably installed in the sliding opening on the cable tray main board 1. The cable tray main board 1 has an opening for the connecting slide plate 8 to move, and it also has mounting holes. This arrangement allows the number of bridge plates 7 and connecting slide plates 8 to be increased or decreased when supporting cables through the openings and sliding openings on the cable tray main board 1. This allows the number of bridge plates 7 and connecting slide plates 8 to be adjusted according to the weight of the cables, increasing the overall support effect of the device, reducing deformation during use, and improving the service life of the device.

[0024] Working principle: When in use, pull the pull plate 5. Pulling the plate 5 moves the limiting rod 6. Then, adjust the distance between the two sets of bridge main boards 1 according to the number of cables. After releasing the pull plate 5, the limiting rod 6 can be inserted into the limiting hole on the support slide plate 3 after the limiting spring 4 returns. This limits the support plate 2 and the support slide plate 3. When there are many supporting cables, multiple sets of connecting slide plates 8 can be placed in the sliding opening on the bridge main board 1 through the opening to increase the support of the device.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
