[0038] Example

[0039] This invention provides a cable tray with adjustable function, see reference. Figures 1-7 As shown, the invention includes a cable tray body 1, with expansion joints 2 slidably mounted at both ends. This invention achieves adjustable length for the cable tray body 1, allowing workers to adjust its length according to on-site requirements, thus improving applicability while ensuring the overall strength and load-bearing capacity of the cable tray body 1 after length adjustment.

[0040] refer to Figures 3-5As shown, the cable tray body 1 includes a cable tray base plate 101. The top end face of the cable tray base plate 101 has symmetrically formed bearing grooves on both sides. Cable tray side plates 102 are symmetrically formed on both sides of the cable tray base plate 101. The inner end face of the cable tray side plate 102 has a receiving groove 103. The inner wall of the receiving groove 103 has a guide groove 104 for the displacement of the guide block 203. A travel groove 106 for the displacement of the travel block 204 is formed through the cable tray side plate 102. The travel groove 106 is connected to the guide groove 104. The arrangement of the guide groove 104 and the guide block 203 improves the stability of the expansion joint 2's displacement on the cable tray body 1.

[0041] The cable tray base plate 101 is provided with a connecting plate 110 connected to the two guide rods 108 below it, and a fixing plate 111 is provided on the top end face of the connecting plate 110. The connecting plate 110 enables the two guide rods 108 to move synchronously.

[0042] Furthermore, the cable tray base plate 101 has multiple first fixing slots 105 through which fixing plates 111 are inserted, and the telescopic base plate 201 has second fixing slots 206 for the fixing plates 111 to be inserted into the first fixing slots 105 and then engaged. The combination of the first fixing slots 105 and the second fixing slots 206 with the fixing plates 111 improves the connection strength and stability between the telescopic joint 2 and the bottom of the cable tray body 1.

[0043] refer to Figures 6-7 As shown, the telescopic joint 2 includes a telescopic base plate 201 disposed in the bearing groove. The telescopic base plate 201 has telescopic side plates 202 symmetrically disposed on both sides in the receiving groove 103. The telescopic side plate 202 has a guide block 203 on its outer end face. The guide block 203 has a traveling block 204 disposed on its outer side. The traveling block 204 has a through guide groove 205. The guide rod 108 is slidably disposed in the guide groove 205. One side of the guide rod 108 has a support frame 114 located below the traveling block 204. The support frame 114 has a through drive groove. The drive rod 116 is slidably disposed in the drive groove.

[0044] The drive rod 116 has a limiting plate 117 located outside the support frame 114 at one end, and a stop plate 115 at the end of the drive rod 116 away from the limiting plate 117. A locking rod 112 is located at the end of the stop plate 115 away from the drive rod 116. The locking rod 112 limits and fixes the displacement of the guide rod 108.

[0045] The guide rod 108 has a first fastening hole through which the locking rod 112 is inserted, and the outer side wall of the bridge plate 102 has a second fastening hole 107 for the locking rod 112 to be inserted into the first fastening hole and then snapped in place.

[0046] A drive spring 113 is coaxially sleeved on the outer side of the drive rod 116. One end of the drive spring 113 is connected to the support frame 114, and the other end of the drive spring 113 is connected to the stop plate 115. The drive spring 113 improves the stability of the locking rod 112 when it is inserted into the first fastening hole and the second fastening hole 107.

[0047] The guide rod 108 has an integrally formed stop plate 115 on its top end face. The stop plate 115 prevents the guide rod 108 from disengaging from the travel block 204.

[0048] The present invention provides an adjustment method for a cable tray with an adjustment function, the method comprising the following steps:

[0049] Step 1: First, pull the limiting plate 117 to drive the drive rod 116 to move the locking rod 112, so that the locking rod 112 is disengaged from the first fastening hole and the second fastening hole 107.

[0050] Step 2: Then, the guide rod 108 in the guide groove 205 is moved downward. The displacement of the guide rod 108 causes the connecting plate 110 to move accordingly, so that the fixing plate 111 on the connecting plate 110 is disengaged from the first fixing groove 105 and the second fixing groove 206.

[0051] Step 3: Then pull the telescopic joint 2 to move it, so that the traveling block 204 slides in the traveling groove 106. The displacement of the traveling block 204 causes the two guide rods 108 and the connecting plate 110 to move accordingly.

[0052] Step 4: Finally, when the expansion joint 2 is moved to the appropriate position, the second fixing groove 206 on the expansion joint 2 is connected to one of the first fixing grooves 105 on the cable tray body 1. Pulling the two guide rods 108 causes the connecting plate 110 to move upward, so that the fixing plate 111 on the connecting plate 110 is inserted into the connected first fixing groove 105 and second fixing groove 206. At the same time, the first fastening hole on the guide rod 108 is connected to one of the second fastening holes 107. Under the elastic force generated by the recovery deformation of the drive spring 113, the locking rod 112 is inserted into the connected first fastening hole and second fastening hole 107, thus completing the length adjustment of the cable tray body 1.

[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
