Description

Technical Field

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

[0002] Cable trays are devices used to support and protect cables, and are widely used in cable laying projects in the power, telecommunications, petroleum, and chemical industries. Their main function is to support cables by laying them on various buildings and pipe rack supports, preventing external damage to the cables during installation, and facilitating subsequent maintenance and repair.

[0003] In existing cable tray technology, cables are usually placed directly in the tray grooves or on the tray without effective limiting measures or fixing structures. During the laying or maintenance process, cables are prone to displacement due to external forces, vibrations or their own weight. Cable displacement may cause cables to squeeze, rub or entangle with each other, which may affect the signal transmission quality or cause insulation wear, creating safety hazards. Utility Model Content

[0004] The main purpose of this utility model is to propose a cable tray that facilitates cable positioning, aiming to solve the technical problem that existing cable trays cannot separate and fix the laid cables when supporting them.

[0005] To achieve the above objectives, this utility model proposes a cable tray for easy cable positioning, comprising: a cable tray body, the cable tray body having a plurality of placement slots along its width for placing cables; a linkage element, the linkage element being mounted on the cable tray body, the linkage element having limit plates, the plurality of limit plates corresponding one-to-one with the placement slots, the linkage element being movable along the width of the cable tray body, thereby realizing the switching of the linkage element between a first position and a second position; when the linkage element is in the first position, the limit plates are outside the placement slots; when the linkage element is in the second position, the limit plates block the opening of the corresponding placement slot, so that the cable is confined within the placement slot.

[0006] Optionally, the cable tray body is fitted with a housing along its width, and the linkage element is installed inside the housing; several placement slots are spaced apart on the housing, and a hidden portion is formed between adjacent placement slots; when the linkage element is in the first position, the limiting piece is located inside the hidden portion; when the linkage element is in the second position, the limiting piece is located inside the placement slot and blocks the opening of the placement slot.

[0007] Optionally, the housing has a first mounting portion and a second mounting portion at both ends, and a plurality of placement slots are spaced apart between the first mounting portion and the second mounting portion. A limit protrusion is provided on the end face of the second mounting portion. One end of the linkage element passes through the first mounting portion and the other end passes through the second mounting portion, and a stop plate is provided on the other end of the linkage element. When the linkage element is in the first position, the stop plate abuts against the end face of the second mounting portion. When the linkage element is in the second position, the second mounting portion abuts against the limit protrusion.

[0008] Optionally, a limiting sleeve is installed at the end of the linkage element away from the stop plate; a first mounting cavity is opened in the first mounting part, the limiting sleeve is located in the first mounting cavity, a first spring is sleeved on the linkage element, and the first spring is restricted between the limiting sleeve and the end wall of the first mounting cavity; when the linkage element is in the first position, the first spring is in a relaxed state; when the linkage element is in the second position, the first spring is in a compressed state.

[0009] Optionally, a limiting groove is provided at the end of the limiting protrusion away from the first mounting part; an anti-rotation protrusion is provided on the side of the stop plate near the second mounting part; the anti-rotation protrusion is used to cooperate with the limiting groove to limit the rotation of the linkage element.

[0010] Optionally, a plurality of limiting plates are slidably disposed on the linkage element, the plurality of limiting plates are spaced apart between the first mounting part and the second mounting part, and a second spring is disposed between the plurality of limiting plates, and a second spring is also disposed between the limiting plates and the end face of the first mounting part and the end face of the second mounting part.

[0011] Optionally, the cable tray body includes a first side wall, a base plate, and a second side wall that are connected to each other; the housing is mounted on the base plate, and the bottom of the placement slot is flush with the top surface of the base plate; the first mounting part and the second mounting part are respectively mounted on the first side wall and the second side wall.

[0012] Optionally, the limiting piece includes a straight segment and an arc segment connected to each other. The straight segment is mounted on the linkage element. When the linkage element is in the second position, the arc segment is located in the placement groove and blocks the opening of the placement groove.

[0013] This utility model provides a cable tray for easy cable positioning. It features an installation groove on the main body of the cable tray and a linkage element with limit plates. The linkage element can switch the limit plates between a first position and a second position. In use, multiple cables are first laid along the length of the cable tray. At this point, the linkage element is in the first position, and the opening of the placement groove is not blocked. Then, the cables are separated, and each cable is individually placed into its designated placement groove. Next, the linkage element is moved to the second position, causing the linkage element with the limit plates to move along the width of the cable tray. At this point, several limit plates block the opening of the placement groove, thus confining each cable within its corresponding placement groove. This invention places the cable individually in the placement slot and simultaneously drives several limiting plates through a linkage element to block the opening of the limiting slot, ensuring that the cable will not shift or detach due to external force or vibration. This allows each cable to be independently fixed in its corresponding placement slot, effectively avoiding the chaotic phenomenon of cable movement and overlap on the cable tray. Furthermore, when it is necessary to replace the cable, simply switch the linkage element from the second position to the first position, so that the limiting plates no longer restrict the cable.

[0029] This utility model proposes a cable tray that facilitates cable positioning.

[0030] In the embodiments of this utility model, such as Figures 1-8 As shown, a cable tray for easy cable positioning includes a cable tray body 1 and a linkage element 3. The cable tray body 1 has a plurality of placement slots 23 along its width direction for placing cables. The linkage element 3 is mounted on the cable tray body 1 and has limiting pieces 4. Each limiting piece 4 corresponds to one of the placement slots 23. The linkage element 3 can move along the width direction of the cable tray body 1, thereby switching between a first position and a second position. When the linkage element 3 is in the first position, the limiting piece 4 is outside the placement slot 23. When the linkage element 3 is in the second position, the limiting piece 4 blocks the opening of the corresponding placement slot 23, so that the cable is confined within the placement slot 23.

[0031] Specifically, by setting an installation groove on the cable tray body 1 and installing a linkage element 3 on the cable tray body 1, and setting a limit piece 4 on the linkage element 3, the linkage element 3 can drive the limit piece 4 to switch between a first position and a second position. In use, multiple cables are first laid along the length direction of the cable tray body 1. At this time, the linkage element 3 is in the first position and the opening of the placement groove 23 is not blocked. Then, the multiple cables are separated and each cable is placed individually in the placement groove 23 from the opening of the placement groove 23. Subsequently, the linkage element 3 is moved to the second position, so that the linkage element 3 with the limit piece 4 moves along the width direction of the cable tray body 1. At this time, several limit pieces 4 block the opening of the placement groove 23 one by one, thereby restricting each cable in the corresponding placement groove 23. This invention places the cable individually in the placement slot 23, and simultaneously drives several limiting plates 4 through the linkage element 3 to block the opening of the limiting slot 261, ensuring that the cable will not shift or detach due to external force or vibration. This makes each cable independently fixed in the corresponding placement slot 23, effectively avoiding the chaotic phenomenon of cable movement and overlap on the cable tray. Furthermore, when it is necessary to replace the cable, simply switch the linkage element 3 from the second position to the first position, so that the limiting plates 4 no longer restrict the cable.

[0032] Optionally, the cable tray body 1 is equipped with a housing 2 along the width direction, and the linkage element 3 is installed inside the housing 2; a plurality of placement slots 23 are spaced apart on the housing 2, and a hidden part 22 is formed between adjacent placement slots 23; when the linkage element 3 is in the first position, the limiting piece 4 is located inside the hidden part 22; when the linkage element 3 is in the second position, the limiting piece 4 is located inside the placement slot 23 and blocks the slot opening of the placement slot 23.

[0033] Specifically, the housing 2 is a box-shaped structure, groove-shaped structure or other protective component with a accommodating function made of metal or plastic. In this embodiment, it is used to accommodate the linkage element 3 and the limiting piece 4. The hidden part 22 is a solid part on the housing 2 without the placement groove 23, which is used to accommodate the limiting piece 4 when the linkage element 3 is in the first position, so as to avoid the limiting piece 4 interfering with the cable laying operation.

[0034] Specifically, when the linkage element 3 is in the first position, the limiting piece 4 is housed within the concealed portion 22, not occupying the space of the placement slot 23, allowing the cable to be placed or adjusted freely without obstruction. When the linkage element 3 switches to the second position, the limiting piece 4 moves into the placement slot 23 and blocks the slot opening, effectively fixing the cable and preventing its displacement. By concealing the limiting piece 4 within the concealed portion 22, not only is the convenience of cable laying improved, but the concealed portion 22 also provides protection for the limiting piece 4 when it is not in use, preventing it from being exposed to external interference or damage.

[0035] In this embodiment, spaced placement grooves 23 can be formed by cutting or stamping on the housing 2, and the unprocessed portions between the placement grooves 23 naturally constitute the hidden portion 22.

[0036] In this embodiment, the housing 2 can be installed along the width direction of the cable tray body 1 by bolt fixing, welding or snap-fit ​​connection, etc.

[0037] Optionally, the housing 2 has a first mounting portion 21 and a second mounting portion 24 at both ends, and a plurality of placement slots 23 are spaced apart between the first mounting portion 21 and the second mounting portion 24. A limiting protrusion 26 is provided on the end face of the second mounting portion 24. One end of the linkage element 3 passes through the first mounting portion 21 and the other end passes through the second mounting portion 24, and a stop plate 31 is provided on the other end of the linkage element 3. When the linkage element 3 is in the first position, the stop plate 31 abuts against the end face of the second mounting portion 24. When the linkage element 3 is in the second position, the second mounting portion 24 abuts against the limiting protrusion 26.

[0038] In this embodiment, the first mounting portion 21 and the second mounting portion 24 are structural components at both ends of the housing 2, fixedly connected to the housing 2 or integrally formed, and used to connect the housing 2 and the cable tray body 1. In this embodiment, both the first mounting portion 21 and the second mounting portion 24 are block structures with through holes, and the two ends of the linkage element 3 pass through the through holes of the first mounting portion 21 and the second mounting portion 24, respectively. The limiting protrusion 26 is a protruding structure provided on the end face of the second mounting portion 24. The limiting protrusion 26 cooperates with the stop plate 31 on the linkage element 3, and fixes the linkage element 3 when it moves to the second position, thereby preventing the linkage element 3 from returning to the first position. The stop plate 31 is provided at one end of the linkage element 3 by fixed connection or integral forming.

[0039] In this embodiment, as Figure 3 and Figure 4 As shown, the first position of the linkage element 3 refers to the end face of the stop plate 31 and the second mounting part 24 abutting; the second position of the linkage element 3 refers to the end face of the stop plate 31 and the limiting protrusion 26 abutting at the end away from the second mounting part 24.

[0040] Specifically, when the linkage element 3 moves along the width direction of the cable tray body 1, the stop plate 31 abuts against the second mounting part 24 or the limiting protrusion 26. When the linkage element 3 is in the first position, the stop plate 31 contacts the end face of the second mounting part 24, and the limiting plate 4 is located in the hidden part 22. When the linkage element 3 is in the second position, the stop plate 31 contacts the limiting protrusion 26, and the limiting plate 4 moves into the placement groove 23 and covers its opening. In this embodiment, through the cooperation of the stop plate 31 with the limiting protrusion 26 and the second mounting part 24 respectively, the precise movement and positioning of the linkage element 3 when switching between the first and second positions are achieved.

[0041] Optionally, a limiting sleeve 33 is installed at the end of the linkage element 3 away from the stop plate 31; a first mounting cavity 211 is provided in the first mounting part 21, the limiting sleeve 33 is partially located in the first mounting cavity 211, a first spring 32 is sleeved on the linkage element 3, and the first spring 32 is restricted between the limiting sleeve 33 and the end wall of the first mounting cavity 211; when the linkage element 3 is in the first position, the first spring 32 is in a relaxed state; when the linkage element 3 is in the second position, the first spring 32 is in a compressed state.

[0042] In this embodiment, the limiting sleeve 33 and the linkage element 3 are detachably connected, preferably by a threaded connection. The end wall of the first mounting cavity 211 and the limiting sleeve 33 together constrain the movement space of the first spring 32. The first spring 32 provides elastic force by compression or relaxation, and after the stop plate 31 separates from the limiting protrusion 26, it drives the linkage element 3 to automatically rebound to the first position.

[0043] Specifically, the first spring 32 is installed in the limited space between the limiting sleeve 33 and the end wall of the first mounting cavity 211, with one end in contact with the limiting sleeve 33 and the other end in contact with the end wall of the first mounting cavity 211. When the linkage element 3 moves from the first position to the second position, the limiting sleeve 33 moves toward the end wall of the first mounting cavity 211 along with the linkage element 3, compressing the first spring 32; conversely, when the linkage element 3 returns to the first position, the first spring 32 relaxes, pushing the limiting sleeve 33 to reset.

[0044] Optionally, a limiting groove 261 is provided at the end of the limiting protrusion 26 away from the first mounting part 21; an anti-rotation protrusion 311 is provided on the side of the stop plate 31 near the second mounting part 24; the anti-rotation protrusion 311 is used to cooperate with the limiting groove 261 to limit the rotation of the linkage element 3.

[0045] In this embodiment, the anti-rotation protrusion 311 is a protrusion provided on the side of the stop plate 31 near the second mounting part 24. By embedding into the limiting groove 261, it forms a fitting structure together with the limiting groove 261 to prevent the linkage element 3 from rotating around its axis when in the second position.

[0046] Specifically, when the linkage element 3 moves to the second position along the width direction of the cable tray body 1, the stop plate 31 abuts against the limiting protrusion 26. At this time, the anti-rotation protrusion 311 is embedded in the limiting groove 261 to form an anti-rotation mechanism, preventing the linkage element 3 from rotating under the influence of external force, thereby causing the stop plate 31 to detach from the limiting protrusion 26. This allows the limiting plate 4 to stably block the opening of the placement groove 23, enhancing the limiting effect on the cable.

[0047] Optionally, a plurality of limiting pieces 4 are slidably provided on the linkage element 3. The plurality of limiting pieces 4 are spaced apart between the first mounting part 21 and the second mounting part 24, and a second spring 5 is provided between the plurality of limiting pieces 4. A second spring 5 is also provided between the limiting pieces 4 and the end face of the first mounting part 21 and the end face of the second mounting part 24.

[0048] In this embodiment, the linkage element 3 is a shaft-shaped structure, the limiting piece 4 can slide freely along its axial direction between the first mounting part 21 and the second mounting part 24 of the linkage element 3, and a second spring 5 is provided on both sides of the limiting piece 4.

[0049] Specifically, the elastic force provided by the second spring 5 allows the limiting plate 4 to automatically adjust its spacing and position when the linkage element 3 moves, thereby adapting to different cables in different placement slots 23. This allows the force applied when the limiting plate 4 contacts the cable to change adaptively, preventing excessive force from being applied to large-sized cables due to different cable sizes, and improving the accuracy of cable limiting.

[0050] Optionally, the cable tray body 1 includes a first side wall 11, a base plate 13, and a second side wall 12 that are connected to each other; the housing 2 is mounted on the base plate 13, and the bottom of the placement groove 23 is flush with the top surface of the base plate 13; the first mounting part 21 and the second mounting part 24 are respectively mounted on the first side wall 11 and the second side wall 12.

[0051] The bottom of the placement groove 23 is on the same plane as the upper surface of the base plate 13. This structure ensures that when the cable is placed in the groove, it can lie flat on the base plate 13, avoiding the cable being suspended or unevenly stressed due to height differences. This allows the cable to lie flat, reducing stress or wear caused by unevenness, thereby improving the stability of the cable.

[0052] In this embodiment, a second mounting cavity 241 is provided in the second mounting part 24, and the second mounting cavity 241 forms a space for the linkage element 3 to pass through; a first mounting plate 25 is integrally formed at the end of the second mounting part 24, and the first mounting plate 25 is larger than the width of the housing 2 in the width direction. The portion of the first mounting plate 25 protruding to both sides of the second mounting part 24 is provided with a first mounting hole 251, which is used to cooperate with the bolt assembly to fix the second mounting part 24 to the second side wall 12.

[0053] In this embodiment, a second mounting plate 27 is mounted on the end face of the first mounting part 21. The width of the second mounting plate 27 is greater than the width of the housing 2. The portion of the second mounting plate 27 protruding to both sides of the first mounting part 21 is provided with a second mounting hole 272. The second mounting hole 272 is used to cooperate with the bolt assembly to fix the first mounting part 21 to the first side wall 11. At the same time, a third mounting hole 273 is also provided on the second mounting plate 27. The third mounting hole 273 is used to cooperate with the bolt assembly to mount the second mounting plate 27 onto the first mounting part 21.

[0054] Correspondingly, holes for the housing 2 to pass through should be provided on the first sidewall 11 and the second sidewall 12. During installation, the end of the housing 2 containing the first mounting part 21 is first passed through the second sidewall 12 and reaches the first sidewall 11. Then, the first mounting plate 25 is fixed to the second sidewall 12 through the first mounting hole 251 on the first mounting plate 25. Then, the second mounting plate 27 is installed on the first mounting part 21, and then the second mounting plate 27 is fixed to the first sidewall 11.

[0055] Correspondingly, a through hole 271 is also provided on the second mounting plate 27, through hole 271 for the end of the linkage element 3 to pass through.

[0056] Optionally, the limiting piece 4 includes a straight segment 41 and an arc segment 42 connected to each other. The straight segment 41 is mounted on the linkage element 3. When the linkage element 3 is in the second position, the arc segment 42 is located in the placement groove 23 and blocks the opening of the placement groove 23.

[0057] In this embodiment, the placement groove 23 is semi-circular. The placement groove 23 and the arc segment 42 together form a circular space for fixing the cable. When the cable is placed in the placement groove 23, the linkage element 3 moves to the second position, and the arc segment 42 enters the placement groove 23 and blocks its opening, thereby restricting the cable from above and preventing the cable from moving in the placement groove 23.

[0058] The structure of the arc segment 42 and the contact surface that are adapted to the shape of the cable can better fit the circular cross-section of the cable, increase the contact area between the limiting plate 4 and the cable, provide uniform limiting force, disperse the contact pressure between the limiting plate 4 and the cable, prevent stress concentration when the limiting plate 4 and the cable come into contact, reduce the risk of wear on the cable insulation layer, and achieve safer and more stable limiting of the cable.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
