Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray climbing structure. Background Technology

[0002] Cable tray systems, as indispensable wiring support components in modern buildings and industrial facilities, are widely used for laying power, communication, and control cables. In complex building structures, cable trays often need to overcome the height differences between floors and equipment to achieve spatial crossing; therefore, the design of their ramp transition structure is crucial.

[0003] Currently, common cable tray climbing methods mainly rely on customized bend-through components. These traditional components usually have significant limitations. Their turning radius and climbing angle are mostly fixed values, resulting in poor flexibility and difficulty in adapting to complex and ever-changing installation environments. Secondly, at the connection between the climbing section and the horizontal section, there are often obvious angle bends or interface gaps. This not only causes uneven stress on the cable during laying, making it prone to insulation wear, but also brings inconvenience to later maintenance and cable expansion. Utility Model Content

[0004] The main purpose of this utility model is to provide a cable tray climbing structure that can adapt to complex installation environments and facilitate the climbing connection of the cable tray.

[0005] To achieve the above objectives, this utility model proposes a cable tray climbing structure, including a climbing frame and a connecting frame;

[0006] The connecting frame is provided in two parts, and the two connecting frames are respectively connected to the two ends of the climbing frame. The climbing frame and the two connecting frames are provided with continuous cable routing cavities, and a guide structure is provided at the bottom of each cable routing cavity. The outer wall of the connecting frame is provided with an adjustment groove parallel to the internal guide structure. The adjustment groove is located at the end of the connecting frame near the climbing frame.

[0007] A connecting rod is rotatably connected to the outer wall of the climbing frame. The two ends of the connecting rod are respectively connected to a connecting frame and are provided with a mating structure passing through the adjustment groove. The mating structure is slidably connected to the adjustment groove. The connecting frame is provided with a locking structure in the wiring cavity relative to the mating structure, which is used to lock the mating structure so that it cannot slide after the connecting frame is adjusted to the angle with the climbing frame.

[0008] In one embodiment of this application, the mating structure includes a connecting shaft and a blocking block. The connecting shaft passes through an adjusting groove, with one end connected to a connecting rod and the other end connected to the blocking block.

[0009] The overlapping area of ​​the blocking block and the connecting frame is greater than the area of ​​the adjusting groove. When the connecting shaft is connected to any end of the adjusting groove, the blocking block covers the side of the adjusting groove adjacent to the wiring cavity.

[0010] In one embodiment of this application, a connecting block is surrounded around the outer periphery of the connecting shaft, and the height of the connecting block is adapted to the height of the adjusting groove, so as to allow the end of the connecting rod to slide stably within the adjusting groove.

[0011] In one embodiment of this application, the connecting frame has limiting frames protruding on both sides of the blocking block within the wiring cavity, the limiting frames and the connecting frame forming a limiting groove, and the blocking block is slidably connected to the limiting groove; the locking structure is connected to the limiting frame.

[0012] In one embodiment of this application, the locking structure includes an abutment, a screw, and a knob. The screw is connected to a limiting frame, one end of the screw is connected to the knob, and the other end passes through a limiting groove and is connected to the abutment. The abutment is connected to the side of the blocking block away from the adjusting groove.

[0013] In one embodiment of this application, the blocking block is provided with a plurality of locking grooves facing the abutment array, and the abutment is provided with a plurality of locking blocks facing the locking groove array; the locking blocks are made of silicone or rubber.

[0014] In one embodiment of this application, there are two connecting rods, which are symmetrically arranged on both sides of the climbing frame, and the connecting frame has two adjustment slots symmetrically opened opposite the two connecting rods.

[0015] In one embodiment of this application, sealing blocks protrude from both ends of the climbing frame, the sealing blocks wrap around the ends of the connecting frame, and the ends of the sealing blocks are provided with adjustment scales.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] The main body of the cable tray climbing structure of this application includes connecting frames on both sides for connecting the cable tray, and a climbing frame between the two connecting frames for changing the inclination angle of the cable tray. The entire climbing structure is provided with a cable routing cavity for arranging cables, and a guide structure is provided for the cables. Through the above structure, cable routing can be carried out quickly after the climbing structure is installed, which can optimize the user experience.

[0018] The outer wall of the connecting frame is equipped with an adjustment groove, which is located near the ramp frame and parallel to the bottom of the connecting frame. A connecting rod is rotatably connected to the ramp frame, with both ends of the connecting rod slidably connected to the corresponding adjustment groove via a mating structure. When the ramp structure is transported to the installation position and needs to be installed, with the locking structure unlocked, one side of the connecting frame can be rotated first to adjust its angle with the ramp frame to meet the user's requirements. After adjustment, the connecting rod on that side can be locked using the locking structure, allowing for quick achievement of the specified installation requirements. Simultaneously, when the connecting frame is adjusted, the connecting rod is driven by the connecting frame and displaced within the adjustment groove. Under the transmission of the connecting rod, the other side of the connecting frame... The connecting rod drives the frame to make a general displacement. After the first connecting frame is fixed in place, the other connecting frame, driven by the connecting rod, bends and the angle between it and the climbing frame is basically the same as the angle between the first connecting frame and the climbing frame. At this time, the connecting rod has room for position adjustment in the adjustment groove. The user only needs to make a slight adjustment on the other side to make the positions of the two connecting frames parallel, making the entire climbing structure easy to install. After the locking structures on both sides are fixed to the connecting rod, the connecting rod will become the structural support of the connecting frames on both sides, which can strengthen the entire climbing structure. The above climbing structure is relatively simple and easy to install and disassemble, which can effectively improve the user experience. Attached Figure Description

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] The following is in conjunction with the appendix Figures 1 to 4 The present invention will be further described below.

[0029] To achieve the above objectives, this utility model proposes a cable tray climbing structure, including a climbing frame 1 and a connecting frame 6;

[0030] There are two connecting frames 6, which are respectively connected to the two ends of the climbing frame 1. The climbing frame 1 and the two connecting frames 6 are provided with continuous cable routing cavities 4, and each cable routing cavity 4 is provided with a guide structure 5 at the bottom. The outer wall of the connecting frame 6 is provided with an adjustment groove 61 parallel to the internal guide structure 5. The adjustment groove 61 is provided at one end of the connecting frame 6 near the climbing frame 1.

[0031] A connecting rod 2 is rotatably connected to the outer wall of the climbing frame 1. The two ends of the connecting rod 2 are respectively connected to a connecting frame 6, and a mating structure 3 is provided through the adjustment groove 61. The mating structure 3 is slidably connected to the adjustment groove 61. The connecting frame 6 is provided with a locking structure 7 in the cable routing cavity 4 relative to the mating structure 3, which is used to lock the mating structure 3 so that it cannot slide after the connecting frame 6 is adjusted to the angle with the climbing frame 1.

[0032] The main body of the cable tray climbing structure of this application includes connecting frames 6 on both sides for connecting the cable tray, and a climbing frame 1 between the two connecting frames 6 for changing the inclination angle of the cable tray. The entire climbing structure is provided with a cable routing cavity 4 for arranging cables, and a guide structure 5 is provided relative to the cables. Through the above structure, cable routing can be quickly completed after the climbing structure is installed, which can optimize the user experience.

[0033] The outer wall of the connecting frame 6 is provided with an adjustment groove 61, which is located near the ramp frame 1 and parallel to the bottom of the connecting frame 6. A connecting rod 2 is rotatably connected to the ramp frame 1, and the two ends of the connecting rod 2 are slidably connected to the corresponding adjustment groove 61 through a mating structure 3. When the ramp structure is transported to the installation position and needs to be installed, in the unlocked state of the locking structure 7, one side of the connecting frame 6 can be rotated first to make the angle between it and the ramp frame 1 meet the user's requirements. After adjustment, the connecting rod 2 on this side can be locked by the locking structure 7, which can quickly achieve the specified installation requirements. At the same time, when the connecting frame 6 is adjusted, the connecting rod 2 will be driven by the connecting frame 6 and displaced within the adjustment groove 61. Under the transmission of the connecting rod 2, the other side... The connecting frame 6 will be driven by the connecting rod 2 to make a general displacement. After the first connecting frame 6 is fixed after adjustment, the other connecting frame 6 will be bent under the drive of the connecting rod 2, and the angle between it and the climbing frame 1 will be basically the same as the angle between the first connecting frame 6 and the climbing frame 1. At this time, the connecting rod 2 has room for position adjustment in the adjustment groove 61. The user only needs to make a slight adjustment on the other side to make the positions of the two connecting frames 6 parallel, so that the entire climbing structure is easy to install. After the locking structures 7 on both sides are fixed, the connecting rod 2 will become the structural support of the connecting frames 6 on both sides, which can strengthen the entire climbing structure. The above climbing structure is relatively simple and easy to install and disassemble, which can effectively improve the user experience.

[0034] A pivot is provided between the climbing frame 1 and the connecting frame 6, and a whole layer of flexible material can be laid at the bottom of the cable routing cavity 4 for connection and to ensure the stability of the entire structure. The guide structure 5 is set on the flexible material and can be used for further fixation. In particular, the flexible material with a certain degree of toughness can be fireproof materials such as flexible ceramic fiber board / blanket, calcium silicate board, and magnesium oxide board. It can be used for fire protection while ensuring that the cable is not rigidly connected in the guide structure 5 and the cable routing cavity 4, thus avoiding cable damage.

[0035] In particular, in one feasible embodiment, the locking structure 7 may include a guide rail facing the mating structure 3, a pressure block on the guide rail, and a rubber or silicone structure on the pressure block. The side wall of the pressure block is connected by a gear, and a knob 74 is connected to the gear. By rotating the knob 74, the mating structure 3 can be pressed tightly by the rubber or silicone material, which can quickly lock the linkage 2 and ensure the user's experience.

[0036] In one embodiment of this application, the mating structure 3 includes a connecting shaft 31 and a blocking block 33. The connecting shaft 31 passes through the adjusting groove 61, one end of the connecting shaft 31 is connected to the connecting rod 2, and the other end is connected to the blocking block 33.

[0037] The overlapping area of ​​the blocking block 33 and the connecting frame 6 is greater than the area of ​​the adjusting groove 61. When the connecting shaft 31 is connected to any end of the adjusting groove 61, the blocking block 33 covers the side of the adjusting groove 61 near the wiring cavity 4.

[0038] One end of the connecting shaft 31 is connected to the end of the connecting rod 2, and the other end is connected to a blocking block 33. The blocking block 33 is used to prevent the connecting rod 2 from falling off the connecting frame 6. The blocking block 33 has a large area. No matter how the connecting rod 2 and the connecting shaft 31 move in the adjusting groove 61, the blocking block 33 can completely seal and cover the adjusting groove 61 to prevent dust from entering the structure, while ensuring the stability of the connection between the connecting rod 2 and the connecting frame 6. After the connecting rod 2 is locked, the connecting rod 2 can be used to support the entire structure, thereby improving the overall structural strength.

[0039] In one embodiment of this application, a connecting block 32 surrounds the outer periphery of the connecting shaft 31. The height of the connecting block 32 is adapted to the height of the adjusting groove 61, so as to allow the end of the connecting rod 2 to slide stably within the adjusting groove 61.

[0040] The connecting block 32 can be circular, which has good sliding performance, allowing the connecting rod 2 to move more smoothly in the adjusting groove 61, and also making it convenient for the user to make smooth adjustments.

[0041] In one embodiment of this application, the connecting frame 6 has a limiting frame 62 protruding on both sides of the blocking block 33 in the wiring cavity 4. The limiting frame 62 and the connecting frame 6 form a limiting groove 63, and the blocking block 33 is slidably connected to the limiting groove 63. The locking structure 7 is connected to the limiting frame 62.

[0042] The limiting groove 63 formed by the limiting frame 62 has the properties of a guide rail, which can limit the movement path of the blocking block 33, making the whole structure easy to adjust. Furthermore, the locking structure 7 is installed on the limiting frame 62, which can guide the locking structure 7 and facilitate the locking of the blocking block 33.

[0043] In one embodiment of this application, the locking structure 7 includes an abutment 71, a screw 73, and a knob 74. The screw 73 is connected to the limiting frame 62. One end of the screw 73 is connected to the knob 74, and the other end passes through the limiting groove 63 and is connected to the abutment 71. The abutment 71 is connected to the side of the blocking block 33 away from the adjusting groove 61.

[0044] The abutment 71 is a disc-shaped abutment structure, which can increase the abutment area, ensure the stability of the abutment, and prevent locking failure. The knob 74, together with the screw 73, can easily press the abutment 71 against the blocking block 33 under the guidance of the limiting frame 62, which can ensure the locking effect.

[0045] In one embodiment of this application, the blocking block 33 is provided with a plurality of locking grooves 34 facing the abutment 71, and the abutment 71 is provided with a plurality of locking blocks 72 facing the locking grooves 34; the locking blocks 72 are made of silicone or rubber.

[0046] The locking block 72 on the abutment 71 is made of silicone or rubber. Both can increase friction and improve the locking effect. When the locking block 72 is pressed against the blocking block 33 by the knob 74, the silicone / rubber has good deformation properties and can be partially fitted into the locking groove 34 to achieve further stable locking and ensure the stability of the structure.

[0047] In one embodiment of this application, there are two connecting rods 2, which are symmetrically arranged on both sides of the climbing frame 1. The connecting frame 6 has two adjusting grooves 61 symmetrically opened relative to the two connecting rods 2.

[0048] The two connecting rods 2 and multiple adjusting grooves 61 work together to balance the overall force on the climbing structure, facilitating overall adjustment while ensuring the overall structural strength of the climbing structure after it is fixed.

[0049] In one embodiment of this application, sealing blocks 11 protrude from both ends of the climbing frame 1. The sealing blocks 11 wrap around the ends of the connecting frame 6, and the ends of the sealing blocks 11 are provided with adjustment scales.

[0050] The sealing block 11 can still cover the end of the connecting frame 6 after the connecting frame 6 is adjusted, which can improve the sealing performance. At the same time, the rotation shaft of the connecting rod 2 and the climbing frame 1 can be on the central axis of the climbing frame 1. Since the end of the sealing block 11 is provided with an adjustment scale, after the connecting frame 6 is adjusted, the bottom or top of the connecting frame 6 will be connected to the sealing block 11. The adjustment scale is set relative to the connecting frame 6, and the adjustment scales at both ends are set independently. When the two connecting frames 6 are parallel, the corresponding position of the bottom or top and the adjustment scale can allow the user to quickly determine whether the adjustment is in the right position. It can quickly adjust the two connecting frames 6 to be parallel and ensure the adjustment accuracy, which can effectively reduce the installation time and improve the installation accuracy.
