[0002] Cable trays are a comprehensive term for rigid structural systems that closely support cables, consisting of straight sections, bends, components, supports (arm-type brackets), and hangers of trays or ladders. Ladder-type cable trays are a type of cable tray where, when laid horizontally, the crossbeams are supported by selecting the optimal span according to the load curve, resulting in lightweight yet high load-bearing capacity.

[0003] Existing ladder-type cable trays are usually fixed with a large number of bolts, which makes installation troublesome, affects construction efficiency, and is inconvenient to disassemble later. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a ladder-type cable tray that can be assembled and installed in combination. This solves the problems that existing ladder-type cable trays typically use a large number of bolts for fixing, which makes installation cumbersome, affects construction efficiency, and is inconvenient for later disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A ladder-type cable tray capable of being assembled includes a ladder body, the ladder body including two oppositely arranged side plates, multiple crossbeams detachably provided between the two side plates, connecting plates symmetrically provided on both sides of the bottom end face of the crossbeams, a limiting plate provided on one side of the bottom of the connecting plate, a folding plate integrally formed with the bottom of the inner end face of the side plate, a pressing plate parallel to the folding plate above the folding plate, first locking holes for locking bolts to be inserted symmetrically on both sides of the folding plate, multiple guide grooves for the insertion of the limiting plate to be inserted on the folding plate between the two first locking holes, and a limiting groove for the limiting plate to be engaged after displacement of one end of the folding plate on one side of the guide groove.

[0007] As a preferred technical solution of this utility model, the press plate is provided with a second locking hole that corresponds one-to-one with the first locking hole.

[0008] By utilizing the above technical solution and the first and second locking holes, the connection strength between the press plate and the folding plate is improved.

[0010] By using the above technical solution and the setting of the fastening groove, displacement of the limiting plate that is stuck in the limiting groove can be avoided.

[0011] As a preferred technical solution of this utility model, the pressing plate on one side of the fastening groove is provided with a limiting plate that can be inserted into the guide groove after being displaced and snapped into the limiting groove.

[0012] The above technical solution utilizes the setting of the fixing plate to further limit the limiting plate that is snapped into the limiting groove, while improving the stability of the connection between the pressing plate and the folding plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model facilitates the assembly and disassembly of the ladder frame body by workers, reduces the amount of bolts used during assembly and disassembly, improves work efficiency, and enhances the overall strength of the ladder frame body after installation. In use, the limiting plate on the crossarm is aligned with the guide groove on the side plate and inserted. When the limiting plate is inserted to the bottom of the guide groove, it shifts, causing one end of the limiting plate to engage with the limiting groove, thus initially fixing the crossarm between the two side plates. Then, the fixing plate on the pressing plate is aligned with the guide groove after the limiting plate shifts and inserted, allowing both sides of the crossarm to smoothly insert into the fastening groove at the bottom of the pressing plate. At this point, the second locking hole on the pressing plate connects with the first locking hole on the side plate. Locking bolts are then inserted into the connected first and second locking holes for fixation, thus completing the assembly of the ladder frame body. Attached Figure Description

[0022] Example

[0023] This utility model provides a ladder-type cable tray that can be assembled in combination, see reference. Figure 1-4 As shown, the ladder frame includes a main body, which comprises two opposing side plates 1. Multiple crossbeams 2 are detachably mounted between the two side plates 1. A folding plate 101, integrally formed with the bottom of the inner end face of each side plate 1, is provided. The folding plate 101 is perpendicular to the side plate 1, and a pressing plate 3, parallel to it, is located above the folding plate 101. This invention facilitates the assembly and disassembly of the ladder frame, reduces the amount of bolts used during assembly and disassembly, improves worker efficiency, and enhances the overall strength of the ladder frame after installation.

[0024] refer to Figure 2 As shown, the folding plate 101 has symmetrical first locking holes 104 on both sides for the insertion of locking bolts 4. The folding plate 101 between the two first locking holes 104 has multiple guide grooves 102 for the insertion of limiting plates 202. The folding plate 101 on one side of the guide groove 102 has a limiting groove 103 for the limiting plate 202 to be engaged after displacement. The limiting groove 103 is connected to the guide groove 102. Through the setting of the limiting groove 103 and the limiting plate 202, the connection between the crossbeam 2 and the side plate 1 can be limited.

[0025] refer to Figure 3 As shown, the bottom end face of the crossbeam 2 is symmetrically provided with a rectangular connecting plate 201 on both sides, and a limiting plate 202 is provided on one side of the bottom of the connecting plate 201. The limiting plate 202 and the connecting plate 201 are integrally formed L-shaped structures.

[0026] refer to Figure 4 As shown, the pressing plate 3 has a second locking hole 301 that corresponds one-to-one with the first locking hole 104. The connection strength between the pressing plate 3 and the folding plate 101 is improved by the provision of the first locking hole 104 and the second locking hole 301.

[0027] The bottom end face of the pressing plate 3 is provided with multiple fastening grooves 303 for pressing and fixing the crossbeam 2. The fastening grooves 303 prevent displacement of the limiting plate 202 that is stuck in the limiting groove 103.

[0028] Furthermore, a limiting plate 202 is provided on the pressing plate 3 on one side of the fastening groove 303. After being displaced and engaged with the limiting groove 103, it can be inserted into the guide groove 102. The fixing plate 302 further limits and fixes the limiting plate 202 engaged in the limiting groove 103, ensuring the stability of the limiting plate 202 engaged in the limiting groove 103, and at the same time improving the stability of the connection between the pressing plate 3 and the folding plate 101.

[0029] The working principle of this utility model is as follows:

[0030] In use, firstly, align the limiting plate 202 on the crossarm 2 with the guide groove 102 on the side plate 1 and insert it. When the limiting plate 202 is inserted to the bottom of the guide groove 102, the limiting plate 202 is displaced, so that one end of the limiting plate 202 is engaged in the limiting groove 103, thereby initially fixing the crossarm 2 between the two side plates 1. Then, align the fixing plate 302 on the pressing plate 3 with the guide groove 102 after the limiting plate 202 has been displaced and insert it, so that one side of the fixing plate 302 is in contact with the connecting plate 201. The two sides of the crossarm 2 are then inserted into the fastening groove 303 at the bottom of the pressing plate 3. At this time, the second locking hole 301 on the pressing plate 3 is connected to the first locking hole 104 on the side plate 1. Insert the locking bolt 4 into the connected first locking hole 104 and second locking hole 301 for fixing, thus completing the assembly of the ladder frame body.
