Abstract
Description
Technical Field
[0001] This utility model relates to the field of building water and electricity engineering technology, and in particular to a cable tray cover plate snap-fit assembly device. Background Technology
[0002] Cable trays are structural systems consisting of supports, brackets, and installation accessories. They are used to lay cable lines inside and outside buildings or in industrial facilities. Through physical support and fixation, they ensure that cables are neatly arranged, operate safely, and are easy to maintain later. Cable tray covers are flat or grid-like components that cover the top of the cable tray. They are connected to the main body of the cable tray by clips, screws, or hinges to form an enclosed space.
[0003] A search revealed that Chinese patent CN221862370U discloses a cable tray cover. Addressing the common issues of existing cable tray covers accumulating dust, having poor heat dissipation, failing to adequately protect internal cables, and exhibiting chaotic and tangled cable arrangements that hinder use, this patent aims to prevent dust from directly entering and accumulating inside the cover, thus affecting its heat dissipation performance. It utilizes protrusions to block wastewater from entering the cover and employs a drainage channel connected to the drain outlet and drainage hole to guide wastewater to the outside, preventing it from harming the cables. Furthermore, symmetrically arranged cable tray plates along the two long sides of the second heat dissipation hole allow for neat and zoned cable arrangement, improving the convenience of cable maintenance.
[0004] While the aforementioned cable trays facilitate cable routing, the existing technology for cable tray covers involves several methods. Some are installed by tightening bolts and nuts, which, while relatively secure, is laborious and cumbersome, requiring considerable time for disassembly. Others are installed using simple clips, which, while easy to install, are prone to detachment due to weak clip engagement. Thus, it is difficult to simultaneously improve the stability of the cover installation and engagement while also ensuring convenient disassembly and assembly. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cable tray cover plate snap-fit assembly device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable tray cover plate snap-fit assembly device, including a cable tray shell, a cover plate shell is provided on the top of the cable tray shell, multiple through slots are provided on both sides of the cable tray shell, and a locking component is provided on the outside of the cable tray shell;
[0007] The locking assembly includes two housings, which are disposed on both sides of the cable tray housing. Two through holes are opened on one side of each housing, and a limiting groove is opened in the middle of one side of each housing. A knob is rotatably connected inside the limiting groove.
[0008] As a further description of the above technical solution:
[0009] The knob has a threaded hole inside, and a connecting plate is slidably connected inside the outer casing. Two connecting posts are fixedly connected to one side of the connecting plate, and a connecting rod is fixedly connected to one end of each of the two connecting posts.
[0010] As a further description of the above technical solution:
[0011] Multiple springs are fixedly connected to one side of the connecting plate, and the multiple springs are fixedly connected to one side of the inner wall of the outer shell.
[0012] As a further description of the above technical solution:
[0013] Both the connecting rod and the connecting plate are fixedly connected to a stud on one side of the middle, and a thin rod is fixedly connected between the two studs. Two limiting frames are fixedly connected to the upper surface of the connecting rod, and a rubber block is provided on the lower surface of the limiting frame.
[0014] As a further description of the above technical solution:
[0015] The outer casing is provided with fixing components on both sides, and the fixing components include two mounting plates, and multiple mounting plates are respectively fixedly connected to both sides of the outer casing.
[0016] As a further description of the above technical solution:
[0017] A bidirectional lead screw is rotatably connected between two of the mounting plates, and a connecting bracket is externally threaded onto the bidirectional lead screw. Multiple connecting brackets are slidably connected to both sides of the housing.
[0018] As a further description of the above technical solution:
[0019] One end of the connecting frame is fixedly connected to a fixing block, and the upper surfaces of the two mounting plates are fixedly connected to fixing sleeves. The inner wall of the fixing sleeves is provided with multiple rubber strips, and one end of the bidirectional lead screw passes through the mounting plate and is fixedly connected to a knob.
[0020] This utility model has the following beneficial effects:
[0021] 1. This utility model, through the setting of the locking component, uses the limiting brackets on both sides to lock the upper surface of the cover shell, which facilitates the limiting and locking of the cover shell. When the rubber block comes into contact with the cover shell, it will be compressed and deformed, which will squeeze the cover shell and help improve the tightness of the cover shell being limited. At the same time, the use of the knob and the corresponding stud thread connection makes it easy to lock the connecting column after the limiting bracket limits the cover shell. This helps to reduce the phenomenon of the limiting bracket detaching from the upper surface of the cover shell due to the displacement of the connecting column. It is convenient to disassemble and assemble, while also fastening and limiting the cover.
[0022] 2. This utility model, through the setting of the fixing component, utilizes the compression of two fixing blocks on the same side with the through hole in the cable tray housing to facilitate the quick fixing of the outer shell to the side of the cable tray housing, which facilitates the quick installation of the locking component. Furthermore, by utilizing the elastic deformation capability of the ring-shaped distributed rubber strips, it is easy to generate relative compressive force on the knob after rotation, increasing the friction force when the knob rotates, so that the knob can be subjected to external multi-directional compressive force and thus be limited, which helps to maintain the locking effect after the bidirectional screw rotates.

[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] As attached Figure 1-7 As shown, one embodiment of this utility model is provided: a cable tray cover plate snap-fit assembly device, including a cable tray shell 1, a cover plate shell 2 is provided on the top of the cable tray shell 1, multiple through slots 3 are provided on both sides of the cable tray shell 1, and a locking component is provided on the outside of the cable tray shell 1.
[0034] The locking assembly includes two housings 4, which are located on both sides of the cable tray housing 1. Two through holes 5 are provided on one side of the housing 4 to facilitate the sliding of the connecting post 9. A limit groove 6 is provided in the middle of one side of the housing 4 for installing a knob 7. The knob 7 is rotatably connected inside the limit groove 6.
[0035] As attached Figure 4 As shown, the knob 7 has a threaded hole inside, and the connecting plate 8 is slidably connected inside the housing 4. Two connecting posts 9 are fixedly connected to one side of the connecting plate 8, and a connecting rod 10 is fixedly connected to one end of the two connecting posts 9. Multiple springs 11 are fixedly connected to one side of the connecting plate 8 to generate a pushing force on the connecting plate 8. The multiple springs 11 are fixedly connected to one side of the inner wall of the housing 4.
[0036] As attached Figure 5 As shown, studs 12 are fixedly connected to the middle of one side of the connecting rod 10 and the connecting plate 8, which match the threads of the knob 7. A thin rod 13 is fixedly connected between the two studs 12 to facilitate the passage of the knob 7. Two limiting brackets 14 are fixedly connected to the upper surface of the connecting rod 10 to facilitate the limiting of the upper surface of the cover shell 2. A rubber block 15 is provided on the lower surface of the limiting bracket 14 to form a squeezing force using elasticity, so that the cover shell 2 is stably assembled and positioned.
[0037] As attached Figure 2As shown, fixing components are provided on both sides of the outer casing 4. The fixing components include two mounting plates 16. Multiple mounting plates 16 are fixedly connected to both sides of the outer casing 4. A bidirectional lead screw 17 is rotatably connected between the two mounting plates 16. The external threads are in opposite directions. A connecting bracket 18 is connected to the external threads of the bidirectional lead screw 17. Multiple connecting brackets 18 are slidably connected to both sides of the outer casing 4. A fixing block 19 is fixedly connected to one end of the connecting bracket 18 to facilitate abutting against both sides of the through groove 3. A knob 22 is fixedly connected to one end of the bidirectional lead screw 17 through the mounting plate 16 for turning to drive the bidirectional lead screw 17 to rotate.
[0038] As attached Figure 7 As shown, the upper surfaces of the two mounting plates 16 are fixedly connected with fixing sleeves 20. The inner wall of the fixing sleeves 20 is provided with multiple rubber strips 21. The rubber strips 21 have a deformable elastic force. The ring-shaped rubber strips 21 help to apply a pushing force to the knob 22, increase the friction force, and reduce the phenomenon of the knob 22 rotating without the action of external force.
[0039] Working principle: When in use, place the outer shells 4 on both sides in a suitable position to limit the cover shell 2 and between the two through slots 3. Then turn the knob 22. Under the action of external rotational force, the knob 22 will rotate, which will drive the double-acting screw 17 to rotate. The double-acting screw 17 will drive the connecting brackets 18 on both sides to slide on the side of the bridge frame shell 1. At this time, the fixing blocks 19 at both ends on the same side will move away from each other under the action of the double-acting screw 17 in opposite directions, so that the fixing blocks 19 are pressed against the inner wall of the through slot 3. After being squeezed, the outer shell 4 is fixed.
[0040] Initially, spring 11 is compressed, and knob 22 is threadedly connected to stud 12 on one side of connecting plate 8. At this time, multiple connecting posts 9 are outside the outer casing 4. Then, cover plate 2 is placed on the upper surface of cable tray casing 1, and knob 7 is turned to separate knob 7 from the corresponding connected stud 12. When separated, spring 11 will release its limit and release its elastic force. Under the pushing action of spring 11, connecting plate 8 will slide inside outer casing 4, which will in turn drive connecting posts 9 to slide inside through hole 5 and move into outer casing 4. Thin rod 13 passes through the middle of knob 7 and moves into outer casing 4, causing two connecting posts 9 to pull. The moving connecting rod 10 then pulls the limiting bracket 14 to the upper surface of the cover shell 2, limiting the upper surface of the cover shell 2. When the limiting bracket 14 moves to the upper surface of the cover shell 2, pressure is generated, pushing the cover shell 2 down onto the cable tray shell 1, thereby making the cover shell 2 and the cable tray shell 1 connected and fastened. At the same time, with the elastic effect of the rubber block 15 rebounding under pressure, the downward pushing effect on the cover shell 2 is enhanced, thereby improving the tightness of the cover shell 2 installation. At this time, the stud 12 on one side of the connecting rod 10 will move to one side of the knob 7. Then, the knob 7 is rotated, and under the action of the thread, the stud 12 moves into the inside of the knob 7, so that the connecting post 9 and the limiting bracket 14 are limited.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
