[0022] The following is combined with Figure 1-5 The utility model is further described.

[0023] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a trough-type cable tray.

[0024] The specific technical solution includes a base plate 1, a retractable assembly 4 and a telescopic top plate assembly 5. Both sides of the base plate 1 are provided with inner grooves 2, and a groove 3 is provided below the base plate 1. The two inner grooves 2 are U-shaped, and the groove 3 is provided between the two inner grooves 2. Figure 2As shown, the retractable component 4 is arranged inside the two inner grooves 2, and the retractable component 4 includes two lateral retractable parts. The lateral retractable parts are used to change the lateral size of the base plate 1. The lateral retractable parts include a screw rod 41 that rotates inside the groove 3, and an anti-slip button is fixed at one end of the screw rod 41, and the ends of the screw rods 41 with the anti-slip button in the two lateral retractable parts are connected. The external thread of the screw rod 41 is connected to the expansion base plate 42, and the expansion base plate 42 slides inside the inner groove 2. The two lateral retractable parts are symmetrically arranged, so the rotation directions of the two screw rods 41 are opposite. The rotation of the screw rod 41 causes the two expansion base plates 42 to move relative to each other, and the lateral adjustment size is achieved under the limit guide of the inner groove 2.

[0025] The retractable assembly 4 also includes two vertical retractable parts, which are respectively arranged on both sides of the two horizontal retractable parts. The two vertical retractable parts are symmetrically arranged. The vertical retractable parts are used to change the vertical size of the trough-type bridge. The vertical retractable parts include a first vertical baffle 43, one side of the first vertical baffle 43 is provided with two first slide grooves 44, one side of the first vertical baffle 43 is provided with a second vertical baffle 45 through two sliders, and the two sliders slide respectively inside the two first slide grooves 44, one side of the second vertical baffle 45 is provided with a second slide groove 46, and one side of the second vertical baffle 45 is provided with a third vertical baffle 47 through two connecting blocks. The connecting blocks slide in the two second sliding grooves 46 respectively. An alignment bar 48 is fixed on one side of the first vertical baffle 43 and the second vertical baffle 45. The alignment bar 48 has a certain elasticity. A plurality of alignment grooves 49 are provided on one side of the second vertical baffle 45 and the third vertical baffle 47. When the second vertical baffle 45 and the third vertical baffle 47 slide upward, the alignment bar 48 will be squeezed and deformed, and when the second vertical baffle 45 and the third vertical baffle 47 slide to one of the alignment grooves 49 corresponding to the alignment bar 48, the alignment bar 48 returns to its original state and is stuck in the corresponding alignment groove 49 to preliminarily position the positions of the second vertical baffle 45 and the third vertical baffle 47.

[0026] The interior of the first vertical baffle 43 and the interior of the second vertical baffle 45 are both provided with an inner cavity 410, and the exterior of the second vertical baffle 45 and the exterior of the third vertical baffle 47 are both provided with a plurality of positioning grooves 411. Positioning pieces 412 and connecting rods 413 are slidably provided inside the two inner cavities 410. The number and positions of the positioning grooves 411 correspond to the alignment grooves 49. When the alignment strips 48 correspond to different alignment grooves 49, the positioning pieces 412 correspond to different positioning grooves 411. One end of the two connecting rods 413 is fixedly connected to the two positioning pieces 412 respectively, and the exterior of the two connecting rods 413 is sleeved with a spring 414. The spring 414 serves to automatically reset the positioning piece 412. One end of the two connecting rods 413 extends to the exterior of the first vertical baffle 43 and the second vertical baffle 45 respectively, and a pulling belt is fixed to the end extending to the exterior, which facilitates pulling the connecting rod 413 out of the inner cavity 410.

[0027] A telescopic top plate assembly 5 is provided above the two vertical retractable parts, and the telescopic top plate assembly 5 includes a first cover plate 51, a retractable groove 52 is opened on one side of the first cover plate 51, and a second cover plate 53 slides inside the retractable groove 52, and a clamping strip 54 is fixed below the first cover plate 51 and below the second cover plate 53. The first cover plate 51 and the second cover plate 53 can be adjusted in width by pulling relative to each other, and the applicable width can be flexibly adjusted according to the lateral dimensions of the base plate 1 and the two expanded bottom plates 42, and the two clamping strips 54 are respectively clamped on the top edges of the two third vertical baffles 47, for limiting the width of the first cover plate 51 and the second cover plate 53.

[0028] To enable those skilled in the art to fully understand the technical solution, this application provides the following overall overview:

[0029] When in use, according to the number and occupied volume of the internal cables, the screw rods 41 in the two horizontal retractable parts can be rotated in opposite directions by toggling the anti-slip button, so that the two expanded bottom plates 42 can move relative to each other. The two expanded bottom plates 42 move out of the inner groove 2 to increase the horizontal size of the bottom frame plate 1, and the two expanded bottom plates 42 move into the inner groove 2 to reduce the horizontal size of the bottom frame plate 1. For the vertical size of the bridge, the connecting rod 413 can be pulled by the pulling belt. The connecting rod 413 drives the positioning piece 412 to pull out the corresponding positioning groove 411 and squeeze the spring 414, and then the second vertical baffle 45 corresponding to the positioning groove 411 is pulled. Or the third vertical baffle 47 is pulled upward, and the positioning piece 412 and the positioning slot 411 are accurately aligned under the corresponding engagement of the alignment strip 48 and the alignment slot 49. After the second vertical baffle 45 or the third vertical baffle 47 is pulled to the appropriate position, the pulling belt is released, and the positioning piece 412 is pushed into the corresponding positioning slot 411 under the reaction force of the spring 414 to reinforce the position of the second vertical baffle 45 and the third vertical baffle 47, and prevent the second vertical baffle 45 and the third vertical baffle 47 from sliding down easily. The internal dimensions of the bridge can be flexibly changed to meet the needs of various projects or environments, and it is highly flexible.
