Description

Technical Field

[0001] This utility model relates to the field of cable trays, and in particular to a trough-type galvanized cable tray. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures. They consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also available.

[0003] A search revealed that Chinese patent "A Novel Hot-Dip Galvanized Trough-Type Cable Tray" (authorization announcement number CN217934910U) discloses a novel hot-dip galvanized trough-type cable tray, comprising a cable tray trough, an upper cover, side wall inserts, layered cable rack plates, cable clamping plates, and rubber pads. The upper cover is positioned above the cable tray trough. Side wall inserts are symmetrically arranged on both sides of the inner surface of the cable tray trough. Layered cable rack plates are positioned above the side wall inserts, perpendicular to the length direction of the side wall inserts. Cable clamping plates, in a V-shape, are fixedly positioned below the layered cable rack plates. This novel trough-type cable tray, through its layered cable rack plates, allows for layered cable laying within the cable tray trough, preventing heat accumulation caused by cable stacking. The cable clamping plates allow for the separate suspension of high-heat-generating cables, preventing them from contacting other cables and reducing the temperature impact on other cables.

[0004] Although the aforementioned cable trays can clamp and limit cables and isolate them through V-shaped cable clamping plates, the number of layered cable trays is large, and the multiple cable clamping plates are not connected. Therefore, when positioning cables, it is necessary to move the cable segments one by one into the cable clamping plates, which is a cumbersome operation. Furthermore, the method of limiting cables solely by the V-shaped angle and rubber pads cannot guarantee the clamping effect in the long term.

[0005] Therefore, a trough-type galvanized cable tray is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a trough-type galvanized cable tray to solve the above-mentioned problems, thereby improving the problem that the traditional cable tray is cumbersome to operate when installing cables and the positioning effect cannot be guaranteed.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a trough-type galvanized cable tray, comprising: a cable tray trough pipe;

[0008] A positioning component, wherein the positioning component is disposed in the cable tray trough;

[0009] The positioning component includes a support plate disposed in the cable tray trough. Four sets of cable positioning hooks are arranged in a horizontal array below the support plate. Each set of cable positioning hooks is provided with a synchronization bar. The lower end of the cable positioning hook is provided with a V-shaped guide and a locking part.

[0010] Preferably, both inner sides of the cable tray trough are fixedly connected to connecting plates. The surface of the connecting plates is provided with strip holes. By using the connecting plates in conjunction with the strip holes, the support plates and cable positioning hooks can be supported and limited. It also makes it convenient for workers to adjust the longitudinal position of the cable positioning hooks.

[0011] Preferably, the positioning component further includes a longitudinal slider fixedly connected to the underside of the support plate. The surface of the longitudinal slider is slidably connected to the strip hole, and the support plate can be longitudinally limited by the longitudinal slider.

[0012] Preferably, a bolt is inserted into the longitudinal slider, and a nut is threaded onto the lower surface of the bolt. The upper part of the nut contacts the connecting plate. By using the bolt and the nut, the position of the support plate can be fixed.

[0013] Preferably, the locking part is circular, and the width of the upper opening of the locking part is smaller than the circular diameter of the locking part. As described above, this can prevent the cable from slipping out and thus wrap and limit the cable.

[0014] Preferably, the cable positioning hook and the support plate are integrally connected, and both the cable positioning hook and the support plate are made of stainless steel. As described above, both the support plate and the cable positioning hook are elastic.

[0015] Preferably, a cable tray cover is provided above the cable tray trough. The cable tray cover is arranged in an inverted U-shape, which can protect the cables in the cable tray trough.

[0016] The beneficial effects of this utility model are:

[0017] The locking part of the cable positioning hook in the positioning component can avoid the problem of loosening due to the gradual decrease of friction after a long time caused by the traditional V-shaped locking positioning method.

[0018] By utilizing the synchronization strip in the positioning component, when installing the cable, you only need to snap the cable into the two cable positioning hooks at the very end and straighten the cable. The cable in the middle will automatically reset into the multiple cable positioning hooks in the middle, achieving a quick installation effect. There is no need for manual manipulation to manually move the cable into the positioning hooks one by one and press them into position, which can effectively save manpower.

[0025] 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.

[0026] In practical implementation: such as Figure 1-5 As shown, a trough-type galvanized cable tray includes: a cable tray trough tube 1; and a positioning component 4, which is disposed in the cable tray trough tube 1.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning component 4 includes a support plate 401 disposed in the cable tray trough 1. Four sets of cable positioning hooks 405 are arranged in a horizontal array below the support plate 401. Each set of cable positioning hooks 405 is provided with a synchronization bar 407. The lower end of the cable positioning hook 405 is V-shaped and has a locking part 406. The positioning component 4 also includes a longitudinal slider 402 fixedly connected to the lower part of the support plate 401. The surface of the longitudinal slider 402 is slidably connected to the strip hole 5. A bolt 403 is inserted into the longitudinal slider 402. A nut 404 is threadedly connected to the lower surface of the bolt 403. The upper part of the nut 404 contacts the connecting plate 3. The locking part 406 is circular. The opening width of the upper end of the locking part 406 is smaller than the circular diameter of the locking part 406. The cable positioning hooks 405 and the support plate 401 are integrally connected. Both the cable positioning hooks 405 and the support plate 401 are made of stainless steel.

[0028] First, the staff places the cable into the multiple cable positioning hooks 405 by placing the synchronization bar 407 at the end of the cable positioning hooks 405, and presses the cable into the locking part 406 of the two outermost cable positioning hooks 405. Then, the cable is pulled tight. At this time, the cable will automatically straighten and enter the locking part 406 of the multiple cable positioning hooks 405 in the middle, achieving the effect of rapid positioning.

[0029] It should be noted that a washer is provided above the nut 404. The diameter of the washer is larger than the width of the strip hole 5 on the surface of the connecting plate 3. Therefore, when the nut 404 is turned upward until the nut 404 drives the washer to contact the bottom of the connecting plate 3, the friction between the washer and the connecting plate 3 can be used to position the support plate 401 as a whole.

[0030] Both inner sides of the cable tray trough 1 are fixedly connected with connecting plates 3, and the surface of the connecting plates 3 is provided with strip-shaped holes 5; a cable tray cover 2 is provided above the cable tray trough 1, and the cable tray cover 2 is arranged in an inverted U-shape.

[0031] It should be noted that the bolts 403, nuts 404, and washers mentioned above are all components with relatively mature existing technology. Specific models can be selected according to actual needs.

[0032] When using this invention, if the worker needs to position the cable, first place the support plate 401 in the cable tray trough 1 and support it on the two connecting plates 3. At this time, the longitudinal slider 402 below the support plate 401 will be inserted into the slot 5 of the connecting plate 3, which can longitudinally limit the support plate 401 and the multiple cable positioning hooks 405. After the worker adjusts the support plate 401 to the required position, insert the bolt 403 from top to bottom into the longitudinal slider 402, and extend the bolt 403 to the lower end surface of the longitudinal slider 402 and tighten the nut 404. Until the nut 404 is turned upwards to below and in contact with the longitudinal slider 402, the washer above the nut 404 will contact the connecting plate 3, and the support plate 401 will be positioned. At this time, the operator can place the cable into the multiple cable positioning hooks 405 through the synchronization strip 407 at the end of the multiple cable positioning hooks 405, and press the cable into the locking part 406 of the two outermost cable positioning hooks 405. Then tighten the cable, and the cable will automatically straighten and enter the locking part 406 of the multiple cable positioning hooks 405 in the middle, achieving the effect of rapid positioning.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
