Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a cable tray with a line positioning mechanism. Background Technology

[0002] Cable trays are support structures used to carry, protect, and manage cables, and are widely used in construction, power, communications, industrial automation, and other fields. Through a reasonable structural design, they ensure that cables are arranged in an orderly manner, operate safely, and are easy to maintain and expand.

[0003] Cable trays are the core carrier for cable laying. They come in various structural forms, including trough type, tray type, ladder type, and mesh type, and are composed of supports, brackets, hangers, and connecting accessories.

[0004] Existing cable trays lack an effective cable positioning mechanism, resulting in cables being randomly placed inside the tray, causing them to become tangled and disorganized, making later maintenance and repair difficult, and hindering the quick and accurate location of target cables, thus increasing maintenance costs and time. Therefore, a cable tray with a cable positioning mechanism is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, current cable trays lack effective line positioning mechanisms, resulting in cables being randomly placed within the tray, causing them to become tangled and disorganized, making later maintenance and repair difficult, and hindering the quick and accurate location of target cables, thus increasing maintenance costs and time. This utility model proposes a cable tray with a line positioning mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A cable tray with a line positioning mechanism, comprising a bracket frame, arc-shaped grooves on both inner walls of the upper end of the bracket frame, and multiple locking holes arranged in an array at the lower end of the inner walls of both sides of the bracket frame. A top cover is provided on the upper part of the bracket frame, and a lock box is fixedly installed at the bottom of the top cover inside the upper end of the bracket frame. Sliding plates are slidably installed on both sides of the lock box, and through holes are arranged in an array on both sides of the lock box. A top rod is slidably installed in the through holes, one end of which is fixedly connected to the sliding plate, and the other end is slidably installed in the arc-shaped groove. Multiple positioning seats are arranged in an array inside the bracket frame, and a sliding groove is provided on the upper part of the positioning seat, in which multiple sizes of positioning seats are slidably installed. The positioning clamp has fixing holes arrayed on both sides of the positioning seat. A fixing plate is provided on the upper part of the positioning clamp, and a through hole is provided in the fixing plate. Sliding rods are slidably installed in both ends of the through hole. The opposite ends of the sliding rods pass through the fixing plate and are slidably installed in the fixing holes. An installation groove is provided at the bottom of the positioning seat. Installation holes are provided on both sides of the inner wall of the installation groove, and a rotating shaft is rotatably installed in the center of the installation groove. Fixing blocks are slidably installed in the installation holes. The outer ends of the fixing blocks are slidably installed in the lock holes. A gear is fixedly installed on the upper end of the rotating shaft, and a turntable is fixedly installed on the lower end. The turntable passes through the positioning seat on both sides and rotates within it. By setting the positioning seat and positioning clamp, positioning and fixing of different specifications of lines can be realized, improving the stability of the line.

[0007] Preferably, guide rods are arranged parallel to each other and fixedly installed in the lock box. Mounting seats are slidably installed on both ends of the guide rods. Connecting rods are rotatably installed on both sides of the mounting seats. The other end of each connecting rod is rotatably installed on the opposite end of the slide. By setting the mounting seats, when the mounting seats slide on the guide rods, they can drive the connecting rods to rotate, thereby pushing the slides to move relative to each other or in opposite directions in the lock box. This realizes the extension and retraction of the top rod in the through hole of the lock box, which facilitates the fixing and separation of the lock box and the bracket frame, and improves the assembly and disassembly efficiency of the cable tray.

[0008] Preferably, a first spring is provided between the mounting seats. The first spring is slidably mounted on the guide rod. The first spring provides elastic restoring force to the mounting seats, enabling quick disassembly without the need for additional pulling force, thus further improving the convenience of operation.

[0009] Preferably, a second spring is provided between the slide rods and slidably installed in the center of the through hole of the fixed plate. A slider is fixedly installed on the upper part of each slide rod. The slider is slidably disposed in the groove and its upper end extends to the outside of the fixed plate. Through the cooperation of the second spring, slide rod, slider and groove, a stable mechanical structure system is formed.

[0010] Preferably, a slide cylinder is fixedly mounted on the top of the bottom mounting groove of the positioning seat on one side of the gear. A brake rod is slidably mounted inside the slide cylinder. A third spring is provided at one end of the brake rod and slidably mounted inside the sleeve. The other end of the brake rod passes through the slide cylinder and is fixedly mounted with a brake block. The other end of the brake block is provided with teeth that mesh with the tooth grooves on the gear. The third spring provides the brake block with a certain elastic pressure, ensuring that the teeth of the brake block are always tightly engaged with the tooth grooves of the gear, thus achieving elastic self-locking.

[0011] Preferably, control rods are rotatably installed on opposite sides of the fixed blocks, and the other ends of the control rods are rotatably connected to the upper two edges of the turntable. By rotating the turntable, the control rods can be moved, thereby controlling the extension and retraction of the fixed blocks.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, during the use of cable trays, involves placing the positioning seat in a suitable position within the bracket frame, rotating a turntable, and using a control rod to cause the fixing blocks on both sides to retract inwards. After the positioning seat is in place, rotating the turntable in the opposite direction causes the fixing blocks to extend outwards under the action of the turntable and the control rod, inserting them into the locking holes at the lower end of the inner walls on both sides of the bracket frame, thus completing the installation of the positioning seat. Based on the size and quantity of the cables, the positions of multiple sized positioning clamps are slidably adjusted within the sliding grooves on the upper part of the positioning seat. The cables are placed between adjacent positioning clamps. The sliding rods within the fixing plates on the upper part of the positioning clamps slide to both sides under the action of a second spring and insert into the fixing holes on both sides of the positioning seat, thus fixing the positioning clamps. This structural design achieves precise positioning and stable fixing of the cables, solving the problem that existing cable trays, due to the lack of an effective line positioning mechanism, result in cables being randomly placed within the tray, causing tangling and disorder, making later maintenance and repair difficult, and hindering the quick and accurate location of target cables, increasing maintenance costs and time. This design improves the overall performance and reliability of the cable tray. Attached Figure Description

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a cable tray with a line positioning mechanism includes a bracket frame 1. Arc-shaped grooves are formed on the inner walls of both sides of the upper end of the bracket frame 1. Multiple locking holes are arrayed on the lower ends of the inner walls of both sides of the bracket frame 1. A top cover 2 is provided on the upper part of the bracket frame 1. A lock box 3 is fixedly installed at the bottom of the top cover 2 inside the upper end of the bracket frame 1. Slide plates 8 are slidably installed on both sides of the lock box 3. Through holes are arrayed on both sides of the lock box 3, and top rods 9 are slidably installed in the through holes. One end of the top rod 9 is fixedly connected to the slide plate 8, and the other end is slidably installed in the arc-shaped groove. Multiple positioning seats 10 are arrayed inside the bracket frame 1. A sliding groove is formed on the upper part of the positioning seat 10, and a sliding rod is slidably installed in the sliding groove. Multiple positioning clamps 11 of various specifications are provided. Fixing holes are arrayed on both sides of the positioning base 10. A fixing plate 12 is provided on the upper part of the positioning clamp 11. A through hole is provided in the fixing plate 12, and a sliding rod 13 is slidably installed in both ends of the through hole. The opposite ends of the sliding rods 13 penetrate the fixing plate 12 and are slidably installed in the fixing holes. A mounting groove is provided at the bottom of the positioning base 10. Mounting holes are provided on both sides of the inner wall of the mounting groove, and a rotating shaft 18 is rotatably installed in the center of the mounting groove. Fixing blocks 16 are slidably installed in the mounting holes, and the outer ends of the fixing blocks 16 are slidably installed in the locking holes. A gear 20 is fixedly installed on the upper end of the rotating shaft 18, and a turntable 19 is fixedly installed on the lower end. The turntable 19 has two sides... All components penetrate the positioning seat 10 and rotate within it. During operation, when using the cable tray, the positioning seat 10 is placed in the appropriate position within the bracket frame 1. The turntable 19 is rotated, and the turntable 19, through the control rod 17, causes the fixing blocks 16 on both sides to retract inward, placing the positioning seat 10 in place. After the positioning seat 10 is in place, the turntable 19 is rotated in the opposite direction, and the fixing blocks 16, under the action of the turntable 19 and the control rod 17, extend outward and insert into the locking holes at the lower end of the inner walls on both sides of the bracket frame 1, completing the installation of the positioning seat 10. According to the size and quantity of the cable, the positions of multiple specifications of positioning clamps 11 are slidably adjusted in the sliding groove on the upper part of the positioning seat 10, and the cable is placed between adjacent positioning clamps 11. The slide rod 13 inside the upper fixing plate 12 slides to both sides under the action of the second spring 14 and inserts into the fixing holes on both sides of the positioning seat 10 to fix the positioning clamp 11, thereby accurately positioning and stably fixing the cable on the positioning seat 10. The top cover 2 together with the lock box 3 is placed on the upper end of the bracket frame 1. Press the top cover 2, and the top rod 9 retracts under the pressure of the inner wall of the bracket frame 1. The mounting seat 5 drives the sliding plates 8 on both sides to slide relative to each other through the connecting rod 6, compressing the first spring 7. When the top rod 9 slides down to the arc groove position, one end slides into the arc groove. Under the action of the elastic restoring force of the first spring 7, the mounting seat 5 slides in the opposite direction, and pushes the sliding plate 8 to slide in the opposite direction through the connecting rod 6, and closes the bracket frame 1 through the cover plate.

[0023] Guide rods 4 are arranged parallel to each other between the slide plates 8 and are fixedly installed inside the lock box 3. Mounting seats 5 are slidably installed on both ends of the guide rods 4. Connecting rods 6 are rotatably installed on both sides of the mounting seats 5. The other end of the connecting rods 6 is rotatably installed on the opposite ends of the slide plates 8. During operation, when the top cover 2 and the lock box 3 are placed on the upper end of the bracket frame 1 and pressed down, the top rod 9 is squeezed by the inner wall of the bracket frame 1. The squeezing force will cause the slide plates 8 to slide into the lock box 3. The slide plates 8 drive the mounting seats 5 to slide relative to the center position along the guide rods 4 through the connecting rods 6.

[0024] A first spring 7 is provided between the mounting bases 5, and the first spring 7 is slidably mounted on the guide rod 4. During operation, when the cable tray is in use, as the top cover 2 is pressed to retract the top rod 9, the mounting base 5 slides along the guide rod 4 toward the center, and the first spring 7 is compressed. When the top rod 9 reaches the arc groove position, the elastic potential energy stored in the first spring 7 begins to be released, and the elastic restoring force pushes the mounting base 5 to slide in the opposite direction, thereby driving the slide plate 8 and the top rod 9 to move, so that the top rod 9 accurately slides into the arc groove and is held in the lock hole, thus completing the fixing action of the top cover 2.

[0025] A second spring 14 is provided between the slide rods 13 and is slidably installed in the center of the through hole inside the fixed plate 12. A slider 15 is fixedly installed on the upper part of each slide rod 13. The slider 15 is slidably disposed in the groove and its upper end extends to the outside of the fixed plate 12. During operation, when the positioning clamp 11 is adjusted to the correct position, the slide rod 13 will slide towards both ends of the through hole of the fixed plate 12 under the elastic restoring force of the second spring 14, and penetrate the fixed plate 12 to insert into the fixing holes on both sides of the positioning seat 10. During the sliding of the slide rod 13, the slider 15 slides along the groove on the fixed plate 12, which plays a role in guiding and stabilizing the movement of the slide rod 13.

[0026] The gear 20 is provided with a slide cylinder 21 on one side, which is fixedly installed at the top of the bottom mounting groove of the positioning seat 10. A brake rod 22 is slidably installed inside the slide cylinder 21. A third spring 24 is provided at one end of the brake rod 22 and is slidably installed inside the sleeve. The other end passes through the slide cylinder 21 and is fixedly installed with a brake block 23. The other end of the brake block 23 has teeth that mesh with the tooth grooves on the gear 20. During operation, when the turntable 19 is subjected to external force and tends to rotate, the gear 20 will also tend to rotate. The gear 20 pushes the brake block 23, causing the brake rod 22 to slide inward toward the slide cylinder 21, compressing the third spring 24. The third spring 24 will undergo a certain degree of elastic deformation according to the magnitude of the external force, absorbing some energy, but always maintaining the meshing of the teeth of the brake block 23 with the tooth grooves of the gear 20, thereby effectively preventing the gear 20 from rotating and ensuring the overall structural stability of the cable tray.

[0027] Control rods 17 are rotatably mounted on opposite sides of each fixing block 16. The other ends of the control rods 17 are rotatably connected to the upper two sides of the turntable 19. During operation, when the positioning seat 10 is placed in the appropriate position within the bracket frame 1 and the turntable 19 is rotated, the turntable 19 is rotatably connected to the control rods 17 through its upper two sides, causing the control rods 17 to move. The control rods 17 apply an inward pulling force to the fixing blocks 16, causing the fixing blocks 16 on both sides to retract inward along the mounting holes. After the positioning seat 10 is in place, the turntable 19 is rotated in the opposite direction. The turntable 19 applies an outward pushing force to the fixing blocks 16 through the control rods 17. The movement trajectory of the control rods 17 changes, pushing the fixing blocks 16 on both sides to extend outward along the mounting holes until they are inserted into the locking holes at the lower end of the inner walls on both sides of the bracket frame 1, thus completing the installation and fixing of the positioning seat 10.

[0028] Working principle: During the use of the cable tray, the positioning seat 10 is placed in the appropriate position within the bracket frame 1. The turntable 19 is rotated, and the turntable 19, via the control rod 17, causes the fixing blocks 16 on both sides to retract inwards, positioning the seat 10 in place. After the positioning seat 10 is in place, the turntable 19 is rotated in the opposite direction, causing the fixing blocks 16 to extend outwards under the action of the turntable 19 and the control rod 17, inserting into the locking holes at the lower end of the inner walls on both sides of the bracket frame 1, thus completing the installation of the positioning seat 10. Based on the size and quantity of the cables, the positions of multiple sized positioning clamps 11 are slidably adjusted within the groove on the upper part of the positioning seat 10, placing the cables between adjacent positioning clamps 11. The upper fixing plate of the positioning clamp 11... Under the action of the second spring 14, the slide rod 13 inside 12 slides to both sides and inserts into the fixing holes on both sides of the positioning seat 10 to fix the positioning clamp 11, thereby accurately positioning and stably fixing the cable on the positioning seat 10. The top cover 2 together with the lock box 3 is placed on the upper end of the bracket frame 1. Press the top cover 2, and the top rod 9 retracts under the pressure of the inner wall of the bracket frame 1. The mounting seat 5 drives the sliding plates 8 on both sides to slide relative to each other through the connecting rod 6, compressing the first spring 7. When the top rod 9 slides down to the arc groove position, one end of it slides into the arc groove. Under the action of the elastic restoring force of the first spring 7, the mounting seat 5 slides in the opposite direction, and pushes the sliding plate 8 to slide in the opposite direction through the connecting rod 6, and closes the bracket frame 1 through the cover plate.
