Description

Technical Field

[0001] This utility model relates to the technical field of spliced ​​fireproof trough-type cable trays, and in particular to a highly stable spliced ​​fireproof trough-type cable tray. Background Technology

[0002] For example, Chinese patent CN221812260U discloses a fireproof trough-type cable tray that is easy to assemble. After pressing the plug rod into the inside of the circular groove, the two shells are spliced ​​together. At the same time, the fixing block on the outside of the right shell slides to the inside of the connecting frame on the outside of the left shell. Then, the plug rod is pushed out of the circular groove by the spring rebound. At the same time, the end of the plug rod away from the spring moves to the insertion holes at the top and bottom of the connecting frame, so that the fixing block is fixed to the inside of the connecting frame. This allows the two shells to be easily and quickly spliced ​​and fixed together.

[0003] However, the splicing trough-type cable trays in the aforementioned application are spliced ​​together using only short inserts and sockets. Under the long-term influence of their own weight, cable weight, and external vibrations, the connection points are prone to loosening and have poor stability. Especially when splicing and installing over long distances, the connection points are prone to collapse due to insufficient strength, leading to gaps or even breakage at the connection, which poses certain safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a highly stable spliced ​​fireproof trough-type cable tray, which solves the technical problem that existing cable tray connection points are prone to loosening or even collapsing under the pressure of their own weight and the weight of the cables, resulting in poor stability. This invention achieves the goal of improving the stability of the cable tray connection points.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a highly stable splicing fireproof trough-type cable tray, including a top cover installed on the top of the cable tray body, and a splicing mechanism for improving splicing stability is provided on the cable tray body.

[0006] The splicing mechanism includes a tenon installed on the left side of the cable tray body, and multiple tenon shoulders are installed on the left end of the cable tray body above the tenon. The right side of the cable tray body is provided with mortise and tenon grooves that match the tenon and tenon shoulders. The cable tray body is provided with a side wall support assembly for side wall auxiliary support, and a locking assembly for locking the splice joint is installed on the cable tray body.

[0007] A further improvement is that the tenon shoulder is an equilateral triangular shoulder with a 45° angle, and the outer side of the mortise has a notch that is equal to the triangular shoulder of the tenon shoulder.

[0008] A further improvement is that the sidewall support assembly includes side slide plates installed at both ends of the left side of the cable tray body, and multiple T-shaped sliders are vertically and equidistantly installed on the side slide plates. The right side of the cable tray body is provided with a slide groove and a T-shaped slide groove that match the side slide plates and T-shaped sliders.

[0009] A further improvement is that the locking component includes a strip groove formed inside the cable tray body and extending through the slide groove into the cable tray body. A tension spring is installed on the inner wall of the strip groove. A strip block matching the strip groove is installed on the other end of the tension spring. Sliding holes are symmetrically formed on the upper and lower sides of the strip block. A compression spring is installed on the inner wall of the sliding hole. A snap-fit ​​block that slides vertically and vertically connected to the sliding hole is installed on the other end of the compression spring. A pull rod is installed in a through hole on the cable tray body that communicates with the strip groove. The pull rod is located inside the tension spring, and one end of it is connected to the strip block.

[0010] A further improvement is that a corresponding slot is also provided on the side plate.

[0011] A further improvement is that multiple partition plates are installed inside the cable tray body, and heat dissipation vents are provided through the cable tray body and the partition plates, and dustproof nets are installed inside the heat dissipation vents on the cable tray body.

[0012] A further improvement is that the top of both sides of the cable tray body is provided with insertion slots, and the top cover is equipped with insertion blocks that match the insertion slots.

[0013] By employing the above technical solution, this utility model provides a highly stable spliced ​​fireproof cable tray, which has at least the following beneficial effects:

[0014] 1. This utility model quickly completes the splicing of two cable trays by inserting the tenon and tenon shoulder on the other cable tray into the mortise and tenon groove on the right side of the initial cable tray body. The tenon shoulder assists the tenon in bearing part of the pressure, so that the cooperation between the tenon and the tenon shoulder can withstand greater weight, improve the overall load-bearing capacity, and thus improve stability.

[0015] 2. By setting the tenon shoulder as an equilateral triangular oblique shoulder at a 45° angle, this utility model increases the contact area at the splicing point of the two cable trays, making the connection between them tighter and effectively limiting the torsion between them, thus improving lateral stability.

[0016] 3. The present invention uses a T-shaped slider to distribute the vertical shear force to the T-shaped groove that it matches. The close contact and interaction between the T-shaped slider and the T-shaped groove further improve the stability of the connection.

[0017] 4. This utility model uses a pull rod to push a strip block through the strip groove on the side slide plate into the cable tray. At this time, the compression spring in the sliding hole on the strip block resets under its own elasticity, thereby pushing the locking block to slide out from the sliding hole and lock onto the inner wall of the cable tray body, thus completing the locking of the two cable trays.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Given the current limitations of existing cable tray technology, where connection points are prone to loosening and even collapse under the weight of the tray itself and the cables, resulting in poor stability, this embodiment provides a highly stable, spliced, fireproof trough-type cable tray. Please refer to... Figures 1-6 This embodiment provides a highly stable, modular fireproof cable tray that improves the stability of cable tray connection points. The highly stable modular fireproof cable tray includes a top cover 2 installed on the top of the cable tray body 1. The cable tray body 1 is equipped with a splicing mechanism 3 to improve splicing stability. The splicing mechanism 3 splices multiple cable tray bodies 1 together and, in conjunction with side wall support components 35, provides support points, improving the stability of the splicing points. A locking component 36 further locks the splicing points of the multiple cable tray bodies 1, further enhancing the stability of the splicing.

[0035] Because existing cable tray connection points are prone to loosening or even collapsing under the pressure of their own weight and the weight of the cables, resulting in poor stability, this device is equipped with a splicing mechanism 3. The splicing mechanism 3 includes a tenon 31 installed on the left side of the cable tray body 1, and multiple tenon shoulders 32 installed on the left end of the cable tray body 1 above the tenon 31. The right side of the cable tray body 1 is provided with mortises 33 and tenons 34 that match the tenon 31 and tenon shoulders 32. The cable tray body 1 is provided with a side wall support component 35 for side wall auxiliary support, and a locking component 36 is installed on the cable tray body 1 to lock the splice.

[0036] The tenon shoulder 32 is an equilateral triangular shoulder with a 45° angle, and the outer side of the mortise 34 has a notch equal to the triangular shoulder of the tenon shoulder 32. The tenon 31 and tenon shoulder 32 of the left end of the other cable tray body 1 are inserted into the mortise 33 and mortise 34 on the right side of the initial cable tray body 1, thereby quickly completing the splicing of the two cable tray bodies 1. The tenon shoulder 32 assists the tenon 31 in bearing part of the pressure, so that the cooperation between the tenon 31 and the tenon shoulder 32 can bear greater weight, improve the overall load-bearing capacity, and thus improve stability. In addition, the setting of the equilateral triangular tenon shoulder 32 with a 45° angle increases the contact area of ​​the two cable tray bodies 1, making the connection between them tighter and effectively limiting the torsion between them, thus improving lateral stability.

[0037] Simply relying on the tenon 31 at the bottom to engage with the mortise 33 would require the tenon 31 to withstand significant pressure. Therefore, the device also includes a side wall support assembly 35. The side wall support assembly 35 includes side slide plates 351 installed at both ends of the left side of the cable tray body 1, and multiple T-shaped sliders 352 are vertically and equidistantly installed on the side slide plates 351. The right side of the cable tray body 1 has grooves 353 and T-shaped grooves 354 that match the side slide plates 351 and T-shaped sliders 352. During splicing, the side slide plates 351 and T-shaped sliders 352 also slide into the grooves 353 and T-shaped grooves 354 simultaneously. The T-shaped sliders 352 can distribute the vertical shear force to the T-shaped grooves 354 they engage with. Through the close contact and interaction between the T-shaped sliders 352 and T-shaped grooves 354, the stability of the connection is further improved.

[0038] Since the existing cable tray body 1 only has one cable routing channel, cables with different functions will accumulate and tangle with each other, making it inconvenient for later maintenance. Therefore, this device has multiple partition plates 41 installed inside the cable tray body 1 to divide the cable tray body 1 into multiple cable routing channels, which facilitates classified cable routing. In addition, heat dissipation vents 42 are provided through the cable tray body 1 and the partition plates 41. A dustproof net 43 is installed in the heat dissipation vents 42 on the cable tray body 1 to dissipate and exhaust the heat inside the cable tray body 1. The dustproof net 43 is set to prevent external dust from entering the interior of the cable tray body 1.

[0039] The cable tray body 1 has plug slots 51 on both sides of the top, and the top cover 2 is equipped with plug blocks 52 that match the plug slots 51. When installing the top cover 2, the plug blocks 52 at the bottom of the top of the cable tray body 1 can be inserted into the plug slots 51 on the top of the cable tray body 1. This not only has a fixing effect, but also makes it easy to disassemble the top cover 2 to inspect the cables inside the cable tray body 1.

[0040] Example 2

[0041] Based on Example 1, such as Figures 1-6 As shown, to prevent the spliced ​​cable tray body 1 from breaking due to tilting, the device is also equipped with a locking component 36. The locking component 36 includes a strip groove 361 that is opened inside the cable tray body 1 and extends through the slide groove 353 into the cable tray body 1. A tension spring 362 is installed on the inner wall of the strip groove 361. A strip block 363 that matches the strip groove 361 is installed on the other end of the tension spring 362. Sliding holes 364 are symmetrically opened on the upper and lower sides of the strip block 363. A compression spring 365 is installed on the inner wall of the sliding hole 364. A snap-fit ​​block 366 that slides up and down connected to the sliding hole 364 is installed on the other end of the compression spring 365. A pull rod 367 is installed in the through hole on the cable tray body 1 that communicates with the strip groove 361. The pull rod 367 is located inside the tension spring 362, and one end of it is connected to the strip block 363.

[0042] The side slide plate 351 also has a corresponding slot 361. After the two cable tray bodies 1 are spliced ​​together, press the pull rod 367 to push the strip block 363 through the slot 361 on the side slide plate 351 into the cable tray body 1 and drive the tension spring 362 to extend. When the strip block 363 enters the cable tray body 1, the compression spring 365 in the sliding hole 364 on the strip block 363 returns to its original position under its own elasticity, thereby pushing the locking block 366 to slide out from the sliding hole 364 and lock onto the inner wall of the cable tray body 1, thus completing the locking of the two cable tray bodies 1.
