DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] In one embodiment, Figure 1-Figure 7 As shown, a layered trough-type cable tray comprises a tray shell 101, a tray cover 102 is provided at the upper end of the tray shell 101, a partition 103 parallel to the bottom surface is provided inside the tray shell 101, the left side of the partition 103 is connected to the left side surface inside the tray shell 101 through a self-locking rotating mechanism, a wiring auxiliary block 402 is provided on the upper surface of the partition 103 and the bottom surface of the tray shell 101, and the tray shell 101 and the tray cover 102 are connected by a snap-on structure.

[0027] In this embodiment, the partition 103 divides the internal space of the bridge housing 101 into two parts, disperses the wiring harness in the bridge housing 101, and reduces the difficulty of later maintenance. The wiring auxiliary block 402 facilitates neat wiring. The clamping structure enables the bridge cover 102 to be firmly clamped on the upper end of the bridge housing 101 to close the bridge housing 101. The self-locking rotating mechanism allows the partition 103 to rotate upward under the action of external force and self-lock. After the external force is removed, the partition 103 maintains its position unchanged, and the wiring harness above the partition 103 is lifted, which is convenient for maintenance of the wiring harness below the partition 103. After the self-locking rotating mechanism is unlocked, the partition 103 rotates downward under the action of gravity to return to its original position.

[0028] In one embodiment, Figure 1-Figure 3 and Figure 6As shown, the self-locking rotating mechanism includes two rotating seats 201 distributed along the front-to-back direction and arranged in the middle of the left side surface of the bridge frame housing 101, the rotating seat 201 is rotatably connected to the partition rotating shaft 202, the front end of the partition rotating shaft 202 is connected to the left end of the partition 103, and the rear end of the partition rotating shaft 202 is coaxially connected to the ratchet 203, and the rear end surface of the rotating seat 201 is provided with a pawl rotating shaft 205, and the pawl rotating shaft 205 is rotatably connected to the pawl 204, and the pawl 204 matches the ratchet 203, and the pawl rotating shaft 205 is sleeved with a torsion spring 206 between the rotating seat 201 and the pawl 204, and one end of the torsion spring 206 contacts the upper surface of the rotating seat 201, and the other end contacts the left side of the lower part of the pawl 204 The upper end of the pawl 204 contacts the unlocking component connected to the inner wall of the bridge frame housing 101, which is used to release the restriction of the pawl 204 on the ratchet 203. When the external force drives the partition 103 to rotate upward, the partition 103 drives the ratchet 203 to rotate through the partition rotation shaft 202. Under the action of the torsion spring 206, the pawl 204 is always close to the ratchet 203, and the ratchet 203 and the pawl 204 are in a sliding state. After the partition 103 is released, the pawl 204 prevents the ratchet 203 from rotating in the opposite direction, thereby keeping the partition 103 in a lifted state, which is convenient for maintaining the wiring harness under the partition 103. The unlocking component pushes the upper end of the pawl 204, so that the lower end of the pawl 204 disengages from the ratchet 203, and the partition 103 can rotate downward to the lowest position.

[0029] In one embodiment, Figure 3-Figure 5 As shown, the unlocking component includes a sliding groove 301 corresponding to the position of the ratchet 203 and extending through the left side wall of the bridge frame housing 101. A sliding bar 302 is slidably provided in the sliding groove 301. The sliding bar 302 is connected to the stop block 303 on the outside of the bridge frame housing 101. The sliding bar 302 is connected to the sliding block 304 on the inside of the bridge frame housing 101. The right side surface of the sliding block 304 is an inclined surface in contact with the upper left side surface of the pawl 204. The upper end of the sliding block 304 is connected to the connecting rod 305. By pressing the connecting rod 305 downward, the connecting rod 305 presses the sliding block 304 downward, and the inclined surface on the right side of the sliding block 304 acts on the upper left side surface of the pawl 204, so that the upper end of the pawl 204 rotates to the right, that is, the lower end of the pawl 204 rotates to the left to disengage from the ratchet 203, and the self-locking rotation mechanism is unlocked.

[0030] In one embodiment, Figure 2 and Figure 3 As shown, a pressing block 306 is provided on the connecting rod 305 , and the upper surface of the pressing block 306 is relatively wide, so as to facilitate pressing down the connecting rod 305 .

[0031] In one embodiment, Figure 7As shown, a support block 401 is provided in the middle of the right side surface of the bridge housing 101 to support the partition 103 so that the partition 103 is in a horizontal state, thereby reducing the load of the self-locking rotating mechanism when not undergoing maintenance and extending its service life.

[0032] In one embodiment, Figure 7 As shown, a handle 403 is provided on the right side of the upper surface of the partition 103 to facilitate lifting the partition 103 and rotating it upward during maintenance.

[0033] In one embodiment, Figure 1 As shown, the snap-in structure includes a snap-in strip 501 arranged on the upper ends of the left and right outer sides of the bridge frame housing 101, and a snap-in groove 502 is provided at the lower ends of the left and right inner sides of the bridge frame cover 102 corresponding to the position of the snap-in strip 501. The bridge frame cover 102 is made of elastic SUS301 stainless steel. When the lower ends of the left and right sides of the bridge frame cover 102 contact the snap-in strip 501, they are deformed and expanded outward. After the snap-in strip 501 enters the snap-in groove 502, the bridge frame cover 102 returns to its original state, so that the bridge frame cover 102 is firmly connected to the top of the bridge frame housing 101.

[0034] The above embodiment discloses a layered trough-type cable tray, in which the partition 103 divides the internal space of the bridge housing 101 into two parts, disperses the wire harness in the bridge housing 101, and reduces the difficulty of later maintenance. In the initial state, the right end of the partition 103 is placed on the support block 401, and the partition 103 is in a horizontal state. When the external force drives the partition 103 to rotate upward, the partition 103 drives the ratchet 203 to rotate through the partition rotating shaft 202. Under the action of the torsion spring 206, the pawl 204 is always close to the ratchet 203, and the ratchet 203 and the pawl 204 are connected. The two parts are in a sliding state. After the partition 103 is released, the pawl 204 prevents the ratchet 203 from rotating in the opposite direction, thereby keeping the partition 103 in a lifted state, which is convenient for maintaining the wiring harness under the partition 103. The connecting rod 305 is pressed down, and the connecting rod 305 presses down the sliding block 304. The inclined surface on the right side of the sliding block 304 acts on the left side surface of the upper part of the pawl 204, so that the upper end of the pawl 204 rotates to the right, that is, the lower end of the pawl 204 rotates to the left and disengages from the ratchet 203. The self-locking rotating mechanism is unlocked, and the partition 103 rotates downward under the action of gravity to return to its original position.

[0035] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
