Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and specifically to a pultruded cable tray. Background Technology

[0002] Extruded cable trays are cable laying carriers made of fiber reinforced polymer (FRP) composite material through an extrusion process. They are designed to solve the pain points of traditional metal cable trays, such as easy corrosion, heavy weight, and complicated installation. They are widely used in special environments such as strong corrosion, humidity, and high voltage.

[0003] Chinese utility model patent with authorization announcement number "CN222802453U" is specifically for "a pultruded cable tray", which includes a pultruded upper tray and a lower tray. Two sets of side plates are fixedly installed on the upper surface of the lower tray. An embedded groove is formed at one end of each side plate, and an elastic plate is detachably installed within the groove. A triangular block is fixedly installed at one end of each elastic plate. The side plates of the lower tray can be inserted into the inner side of the upper tray, and simultaneously, the triangular block of the lower tray is pressed and slid into an inclined sliding surface, and then springs into a mating opening via the elastic plate. The inclined sliding surface is located at both ends of the inner side of the upper tray, and the mating opening is located at one end of the upper tray and connected to the inclined sliding surface. A quick-release mechanism is detachably installed on the upper surface of the upper tray. During the use of the aforementioned device, the upper cable tray relies on an elastic plate to lock and fix the triangular blocks inside the mating joint, thereby realizing the assembly connection between the lower and upper cable trays. The mating joint of the upper cable tray usually has multiple triangular blocks locked at the same time. When the cable tray needs to be disassembled, although the inclined sliding surface facilitates the sliding of the triangular blocks, some triangular blocks inevitably remain stuck in the mating joint. This makes it impossible for the operator to apply pressure to all triangular blocks at the same time to squeeze the elastic plate, and to disassemble multiple triangular blocks from the mating joint of the upper cable tray at the same time. This results in significant inconvenience during the disassembly of the upper and lower cable trays, affecting the disassembly efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pultruded cable tray, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a pultruded cable tray, including an upper tray and a lower tray. The outer wall of the upper tray is provided with a fitting opening on one side, and the inner wall of the upper tray is provided with oblique grooves on opposite sides. The upper end of the lower tray is fitted onto the lower part of the inner wall of the upper tray. The lower tray is provided with a disassembly and assembly component on one side near the top. The disassembly and assembly component is used to facilitate the disassembly and assembly of the upper and lower trays. The assembly / disassembly assembly includes a butterfly handle, one end of which is fixedly connected to a rotating rod. Both sides of the lower bridge frame have through holes at their lower interior positions, and the rotating rod is rotatably sleeved inside the through holes.

[0006] Furthermore, movable cavities are evenly arranged on both sides of the lower bridge frame. The inner wall of each movable cavity has a fixed inner hole. An installation sleeve is fixedly installed on the inner wall of the fixed inner hole. A compression spring is fixedly installed on one end of the inner wall of the installation sleeve. A movable piece is fixedly installed on one end of the compression spring. An elastic push rod is fixedly connected to one end of the movable piece. The movable piece is slidably sleeved inside the installation sleeve.

[0007] Furthermore, a hinge rod is fixedly sleeved inside one end of the elastic push rod, and hinge blocks are rotatably sleeved on the outer sides of both ends of the hinge rod. A movable plate is fixedly connected to one end of the hinge block, and the lower end of the movable plate is fixedly sleeved on the outer side of the rotating rod. A locking block is fixedly connected to the upper end of the movable plate.

[0008] Furthermore, one side of the movable plate is in contact with and fits inside the inclined groove of the upper bridge frame, and the locking block is inserted into the fitting opening of the upper bridge frame.

[0009] Furthermore, mounting blocks are fixedly installed on one end of both sides of the lower bridge frame, and a fixing plate is fixedly connected to one end of the mounting block. A screw is rotatably sleeved inside the fixing plate.

[0010] Furthermore, a threaded cylinder is rotatably sleeved on the outer side of one end of the screw, and the outer wall of the threaded cylinder is fixedly sleeved inside the butterfly handle.

[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, through the disassembly and assembly of components, allows for the separation of the upper and lower cable trays. When the operator rotates the butterfly handle, the rotating rod rotates, and the rotating rod is fixedly connected to multiple movable plates, thereby enabling the rotation of multiple locking blocks. The multiple locking blocks disengage from the mating joint. Compared with the prior art where the mating joint of the upper cable tray relies on an elastic plate to form a locking and fixing of the triangular blocks, the inclined sliding surface facilitates the sliding of multiple triangular blocks during cable tray disassembly. This avoids the operator being unable to apply pressure to all triangular blocks simultaneously to squeeze the elastic plate, thus solving the problem that multiple triangular blocks cannot disengage from the mating joint of the upper cable tray, resulting in significant inconvenience during the disassembly of the upper and lower cable trays.

[0012] 2. By rotating the screw, the screw moves forward inside the fixed plate. Further, the screw rotates and moves into the threaded cylinder of the butterfly handle, thereby fixing the butterfly handle and the rotating rod. This prevents the movable plate and the locking block from coming off the mating joint and prevents the upper and lower bridge frames from becoming loose. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Reference Figures 1 to 5 This is the first embodiment of the present utility model, which discloses a pultruded cable tray, including an upper cable tray 1 and a lower cable tray 2. The outer wall of the upper cable tray 1 is provided with a fitting opening 11 on one side, and the inner wall of the upper cable tray 1 is provided with a slanted groove 12 on one side opposite to each other. The upper end of the lower cable tray 2 is sleeved on the lower part of the inner wall of the upper cable tray 1. The lower cable tray 2 is provided with a disassembly and assembly component 4 on one side near the upper part. The disassembly and assembly component 4 is used to facilitate the disassembly and assembly of the upper cable tray 1 and the lower cable tray 2. The assembly / disassembly component 4 includes a butterfly handle 41, one end of which is fixedly connected to a rotating rod 47. Through holes 44 are provided on both sides of the lower bridge frame 2 near the bottom. The rotating rod 47 is rotatably sleeved inside the through holes 44 and can rotate within them. Movable cavities 46 are equally arranged on both sides of the lower bridge frame 2. The movable cavities 46 provide space for the movable plate 42 and the locking block 43 to rotate at an angle. A fixed inner hole 45 is provided on the inner wall of the movable cavity 46. An installation sleeve 48 is fixedly installed on the inner wall of the fixed inner hole 45. A compression spring 410 is fixedly installed on one end of the inner wall of the installation sleeve 48. A movable piece 411 is fixedly installed on one end of the compression spring 410. The movable piece 411 moves telescopically within the installation sleeve 48, driven by the elastic force of the compression spring 410. An elastic push rod 412 is fixedly connected to one end of the movable piece 411, which slides within the installation sleeve 48.

[0019] A hinge rod 413 is fixedly sleeved inside one end of the elastic push rod 412. A hinge block 49 is rotatably sleeved on the outer side of both ends of the hinge rod 413. A movable plate 42 is fixedly connected to one end of the hinge block 49. The lower end of the movable plate 42 is fixedly sleeved on the outer side of the rotating rod 47. A locking block 43 is fixedly connected to the upper end of the movable plate 42. One side of the movable plate 42 contacts and fits inside the inclined slide groove 12 of the upper bridge frame 1. The upper bridge frame 1 is placed in the corresponding position of the lower bridge frame 2, ensuring that the upper end of the movable plate 42 is aligned with the inclined slide groove 12 of the upper bridge frame 1. The locking block 43 is inserted into the mating opening 11 of the upper bridge frame 1.

[0020] In use, first, place the upper bridge frame 1 in the corresponding position of the lower bridge frame 2, ensuring that the upper end of the movable plate 42 is aligned with the inclined slide groove 12 of the upper bridge frame 1, and the locking block 43 is aligned with the approximate direction of the mating opening 11. Continue to press the upper bridge frame 1 downwards, further driving the locking block 43 and the movable plate 42 to rotate at an angle and move closer to the inside of the movable cavity 46. This, in turn, causes the elastic push rod 412 and the moving piece 411 to retract and move inside the mounting sleeve 48, compressing the compression spring 410. When the locking block 43 is inserted into the... Inside the fitting opening 11 of the upper bridge frame 1, the movable plate 42 is tightly fitted into the inclined slide groove 12. Due to the release of the compression spring 410, the movable plate 411 and the elastic push rod 412 extend and move. At this time, the hinge rod 413 rotates inside the hinge block 49, which in turn causes the movable plate 42 to rotate the rotating rod 47, thereby inserting the locking block 43 into the fitting opening 11. When the upper bridge frame 1 and the lower bridge frame 2 are disassembled, the operator only needs to use other tools to push out one of the locking blocks 43. 3. Simultaneously rotate the butterfly handle 41, and the rotating rod 47 drives the lower end of the movable plate 42 to rotate in the opposite direction, causing the upper end of the movable plate 42 to swing towards the inclined slide groove 12. When the upper end of the movable plate 42 swings outward, it pulls the elastic push rod 412 through the hinge block 49 and the hinge rod 413, which in turn drives the moving plate 411 to continue compressing the spring 410. Multiple locking blocks 43 disengage from the engagement port 11. As the upper end of the movable plate 42 continues to swing, the locking blocks 43 gradually withdraw from the engagement port 11. When the locking blocks 43 are completely disengaged from the engagement port 11, the upper plate can be directly... The cable tray 1 is removed from the lower cable tray 2, and the disassembly is completed. Multiple movable plates 42 are fixedly connected by the rotating rod 47, so that multiple locking blocks 43 can be rotated. Compared with the existing technology where the upper cable tray 1 relies on the elastic plate to lock and fix multiple triangular blocks in the fitting port 11, this can avoid the operator not being able to apply pressure to all triangular blocks at the same time to squeeze the elastic plate, and prevent multiple triangular blocks from detaching from the fitting port 11 of the upper cable tray 1, which would cause obvious inconvenience during the disassembly of the upper cable tray 1 and the lower cable tray 2. Example 1:

[0021] Reference Figure 1 and Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: mounting blocks 32 are fixedly installed on one end of both sides of the lower bridge frame 2. A fixing plate 3 is fixedly connected to one end of the mounting block 32. A screw 31 is rotatably sleeved inside the fixing plate 3. A threaded cylinder 33 is rotatably sleeved on the outer side of one end of the screw 31. The outer wall of the threaded cylinder 33 is fixedly sleeved inside the butterfly handle 41.

[0022] In use, when the movable plate 42 and the locking block 43 are unlocked or locked, the upper bridge 1 and the lower bridge 2 are locked. By rotating the screw 31, the screw 31 rotates and moves forward inside the fixed plate 3. The screw 31 then rotates and moves into the threaded cylinder 33 of the butterfly handle 41, thereby fixing the butterfly handle 41 and the rotating rod 47. This prevents the movable plate 42 and the locking block 43 from coming off the outside of the mating opening 11, and prevents the upper bridge 1 and the lower bridge 2 from becoming loose.

[0023] The remaining structure is the same as that in Example 1.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
