Description

Technical Field

[0001] This utility model belongs to the field of cabinet cable wiring in power equipment, and specifically relates to a cable tracking device suitable for deep-sized chassis. Background Technology

[0002] Currently, power equipment cabinets include various single-unit chassis (19 inches wide) that use rear-out cabling, which are pulled out and inserted into the cabinet using guide rails on both sides. To prevent damage to the rear cables when these single-unit chassis are pulled out and inserted into the cabinet, a cable-following device needs to be designed at the rear of the chassis to support the cables.

[0003] Currently, cable tracking devices typically employ an elbow-type structure, and the chassis width is 19 inches, therefore the chassis depth cannot exceed 450mm. If the depth of a single chassis exceeds 800mm, the commonly used tracking devices cannot meet the requirements for tracking the tail cable. For example, if multiple tracking sections are added, the number of rotation points between them also increases. When the chassis is pulled out and then pushed back into the cabinet, the tracking device, being in a straightened state, cannot rotate with the joints, preventing the tracking device from switching back to a folded state.

[0004] In existing patented technologies, such as patent application CN202311540530.0, a universal cable tray device for server racks is proposed. The technical solution adopted is to disassemble the fixed-length cable trays in the prior art and assemble them by connecting them together, so that the length of the front (rear) cable tray assembly is adjustable, which can meet the usage requirements of sub-units of different depths. In patent application CN202310343291.3, a cable tray mechanism for small products that can meet the movement and disassembly functions of the products is disclosed. The technical solution adopted is to set a support beam at the rear of the sub-unit and fix it on the movable part of the guide rail located on both sides of the sub-unit; the movable end of the cable tray mechanism is connected to the support beam through a quick lock, and the fixed end of the cable tray mechanism is fixed inside the server rack.

[0005] It can be seen that in the above technical solutions, even if a cable tray device that can adapt to different depths is proposed, the method used is to increase the length of the cable tray assembly. However, when the overall width of the chassis is relatively short compared to the depth of the cabinet, and multiple levels of cable tray units are required, the existing technology still cannot effectively solve similar problems.

[0006] Therefore, there is an urgent need for a cable tracking device that can be used in deep chassis and can be applied to a variety of scenarios. Utility Model Content

[0007] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a cable following device suitable for large-depth chassis, wherein the problem that multiple cable following units cannot effectively follow the chassis movement is overcome by configuring an elastic mechanism, so that the cable following device can be configured with multiple cable following units for application in large-depth chassis.

[0014] As a further improvement of this utility model, the first sliding unit is provided with a groove extending along the first direction, and the second sliding unit is disposed in the groove, so that the second sliding unit can reciprocate in the groove along the first direction.

[0015] As a further improvement of this utility model, the first sliding unit is provided with a guide hole extending along a first direction, and the guide hole communicates with the groove;

[0016] The second sliding unit is provided with a guide member, which passes through the guide hole.

[0017] As a further improvement of this utility model, the outer wall surface of the first sliding unit is provided with a protrusion, and the protrusion and the guide member are spaced apart along the first direction.

[0018] One end of the elastic element is connected to the guide element, and the other end is connected to the protrusion.

[0019] As a further improvement of this utility model, a sliding part is provided between the groove and the second sliding unit. The sliding part consists of a plurality of sliding parts spaced apart along the first direction, so as to realize the connection between the first sliding unit and the second sliding unit.

[0020] As a further improvement of this utility model, the sliding part includes a roller and a roller sleeved on the roller. The roller is rotatably connected to the first sliding unit through the roller, and the outer wall surface of the roller abuts against the second sliding unit.

[0023] One end of the second seat is fixedly connected to the cabinet, and the other end is rotatably connected to the cable tracking unit.

[0028] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0029] In summary, the technical solutions conceived by this utility model have the following beneficial effects compared with the prior art:

[0030] (1) The cable following device of this utility model is applicable to the large-depth size chassis. It is equipped with an elastic mechanism for corresponding two cable following units. The elastic mechanism provides a pre-tightening force to the two cable following units, so that the two cable following units can be folded according to the state change of the elastic mechanism, thereby controlling the rotation direction of the two cable following units. This avoids the situation where multiple cable following units cannot effectively follow the chassis movement when the chassis moves, thus causing jamming. This allows multiple cable following units to be configured in the large-depth size chassis, thereby realizing the cable following operation of the large-depth size chassis, especially meeting the usage requirements of the cable following operation at the rear of the chassis with a depth of 800mm.

[0031] (2) The cable-following device of this utility model is suitable for chassis with large depth. It is provided with a first sliding member and a second sliding member that are slidably connected by corresponding elastic members, so as to enhance the structural stability of the elastic mechanism and maintain a stable connection between the two cable-following units.

[0032] (3) The cable tracking device of this utility model is applicable to the chassis with large depth. Through the configuration of the guide and the guide hole, the first sliding member and the second sliding member can slide stably relative to each other in the first direction. Furthermore, through the setting of the guide and the protrusion, the elastic member is set outside the two sliding members, so that the selection of the elastic member is not limited by the size of the sliding member. The relative sliding distance of the two sliding members can also be controlled by the length of the guide hole in the first direction.

[0033] (4) The cable tracking device of this utility model is applicable to a large depth chassis. It provides a sliding part between the first sliding member and the second sliding member, so that the first sliding member and the second sliding member form a stable sliding match, thereby avoiding the situation where the first sliding member and the second sliding member are stuck and cannot slide relative to each other.

[0034] (5) The cable tracking device of this utility model is applicable to chassis with large depth. It can be applied to chassis with large depth. When the chassis is pulled out and inserted, the cable tracking device can fold itself under the action of the elastic mechanism. This allows the cable tracking device to automatically fold when the chassis is inserted, thereby ensuring the stability and safety of the overall structure. At the same time, the setting of multiple cable tracking units allows it to be effectively applied when facing chassis with small width. Attached Figure Description

[0050] Example:

[0051] The preferred embodiment of this utility model includes a cable tracking device suitable for deep-size chassis, such as... Figures 1-9As shown, the cable tracking device is located between the chassis 2 and the cabinet 1. The cable tracking device includes a cable tracking assembly 5, wherein both ends of the cable tracking assembly 5 are rotatably connected to the chassis 2 and the cabinet 1, respectively. The cable tracking assembly 5 includes at least two cable tracking units arranged in sequence, and adjacent cable tracking units are rotatably connected. Through the rotatable connection between each cable tracking unit, the cable tracking assembly 5 can be unfolded and extended or folded for storage. Correspondingly, the cable tracking assembly 5 also includes an elastic mechanism 504, both ends of which are connected to the two cable tracking units. When the two cable tracking units rotate and unfold, the elastic mechanism 504 applies a pre-tightening force to the two cable tracking units, so that the two cable tracking units can return to the folded state under the action of the elastic mechanism 504. Thus, the cable tracking assembly 5 has a self-storage capability. In practical applications, when the chassis 2 is retracted into the cabinet 1, the two cable tracking units move closer to each other under the action of the elastic mechanism 504, thereby driving the cable tracking units to rotate relative to each other, so that the cable tracking assembly 5 as a whole switches from the unfolded state to the folded state.

[0052] Specifically, the cable tracking unit includes a first cable tracking unit 501 located at the first end of the cable tracking assembly 5 and a second cable tracking unit 502 located at the second end of the cable tracking assembly 5. No additional cable tracking unit is required between the first cable tracking unit 501 and the second cable tracking unit 502. The two adjacent ends of the first cable tracking unit 501 and the second cable tracking unit 502 are rotating ends, and the two rotating ends are rotatably connected to achieve the rotatable connection between the first cable tracking unit 501 and the second cable tracking unit 502. The end of the first cable tracking unit 501 opposite to its rotating end is the connection end of the chassis 2, so as to be rotatably connected to the chassis 2. The end of the second cable tracking unit 502 opposite to its rotating end is the connection end of the cabinet 1, so as to be rotatably connected to the cabinet 1.

[0053] Furthermore, an elastic mechanism 504 is provided between the first thread unit 501 and the second thread unit 502. The two ends of the elastic mechanism 504 are respectively connected to the first thread unit 501 and the second thread unit 502, so that the two thread units fold closer to each other under the action of the elastic mechanism 504. More preferably, the elastic mechanism 504 can be set as a spring.

[0054] Furthermore, the elastic mechanism 504 includes a first sliding unit 5041, a second sliding unit 5042, and an elastic element 5044. The first sliding unit 5041 and the second sliding unit 5042 are slidably connected, and the ends of the two sliding units away from each other are the connecting ends, which are used to rotatably connect with the following unit. Correspondingly, the elastic element 5044 is disposed between the two sliding units to provide preload when the two sliding units make relative separation movements (i.e., the elastic mechanism 504 follows the two following units as they unfold).

[0055] In one embodiment, the first sliding unit 5041 is a tube closed at one end, and the second sliding unit 5042 is a rod. The second sliding unit 5042 is disposed within the first sliding unit 5041, and the elastic element 5044 is disposed inside the tube and connected to the end of the rod and the inner wall surface of the closed end of the tube, respectively. Further, a guide hole is provided on the tube, communicating with the internal space of the tube, and the length direction of the guide hole is the same as the axial direction of the tube. A guide element 5045 is correspondingly provided on the rod, matching the guide hole, so that the rod does not rotate relative to the tube when sliding inside, ensuring stability during relative sliding. Further explanation: the direction of relative sliding between the two sliding units is a first direction.

[0056] In another embodiment, the first sliding unit 5041 has a groove extending along a first direction, and the second sliding unit 5042 is disposed in the groove, slidingly matching the inner wall surface of the groove. Further, the groove can be a T-shaped groove, and the guide member 5045 is also provided corresponding to the T-shaped groove. The T-shaped groove also prevents the second sliding unit 5042 from detaching from the first sliding unit 5041.

[0057] In a preferred embodiment, a guide hole extending in a first direction is provided on the wall surface of the first sliding unit 5041 away from the groove. The guide hole communicates with the groove. A guide member 5045 is correspondingly provided on the second sliding unit 5042. The guide member 5045 and the second sliding unit 5042 are detachably connected so that the guide member 5045 is installed after the second sliding unit 5042 is placed in the groove of the first sliding unit 5041. The opening of the "T"-shaped groove allows the guide member 5045 to pass through and be fixedly connected to the second sliding unit 5042.

[0058] Furthermore, the second sliding unit 5042 has through holes penetrating its upper and lower walls. The guide member 5045 includes a column and a mounting plate 5046 disposed at one end of the column. One end of the column passes through the through hole of the second sliding unit 5042 and the guide hole of the first sliding unit 5041, while the mounting plate 5046 at the other end abuts against the second sliding unit 5042. The mounting plate 5046 and the second sliding unit 5042 are connected by screws to fix the guide member 5045 on the second sliding unit 5042. By setting the length of the guide hole in the first direction, the displacement range of the elastic mechanism 504 as a whole is controlled, thereby preventing the second sliding unit 5042 from coming out of the first sliding unit 5041. More preferably, a protrusion 5043 is provided on the wall surface of the first sliding unit 5041 away from the groove. The protrusion 5043 has a columnar structure and is located at the end of the first sliding unit 5041 away from the second sliding unit 5042. Correspondingly, one end of the elastic member 5044 is connected to the guide member 5045, and the other end is connected to the protrusion 5043. This eliminates the need for the elastic member 5044 to be located inside the groove, thereby miniaturizing the first sliding unit 5041 and the second sliding unit 5042. At the same time, it also increases the selection range of the elastic member 5044. The elastic member 5044 is preferably a spring.

[0059] Furthermore, a sliding portion is provided between the two side walls of the second sliding unit 5042 and the inner side wall of the groove of the first sliding unit 5041. The sliding portion is provided on both sides of the second sliding unit 5042, and multiple sliding portions are spaced apart along the first direction to achieve sliding matching between the first sliding unit 5041 and the second sliding unit 5042.

[0060] In one embodiment, the sliding part is a ball bearing. Multiple mounting grooves are provided on the inner walls of both sides of the first sliding unit 5041 for mounting the ball bearing. In order to prevent the ball bearing from falling out of the first sliding unit 5041, the ball bearing is concentrated at one end of the first sliding unit 5041 away from its connecting end. At the same time, it is necessary to control the displacement range of the second sliding unit 5042. Therefore, the length of the guide hole in the first direction is adjusted accordingly so that the ball bearing is always limited by the first sliding unit 5041 and the second sliding unit 5042, thereby preventing the ball bearing from falling out.

[0061] In another embodiment, the sliding part includes a roller 5048 and a roller 5047 sleeved on the roller 5048. The roller 5048 is disposed in the groove of the first sliding unit 5041, and the roller 5048 can be fixedly connected to the first sliding unit 5041. Then, the roller 5047 is rotatably connected to the roller 5048, so that the roller 5047 is rotatably connected to the first sliding unit 5041. Alternatively, the roller 5048 is rotatably connected to the first sliding unit 5041, and then the roller 5048 is fixedly connected to the roller 5048, which also makes the roller 5047 rotatably connected to the first sliding unit 5041.

[0062] Furthermore, since the roller 5048 is connected to the inner wall of the groove, the two side walls of the second sliding unit 5042 are respectively provided with slide rails extending to both sides. The sliding connection between the first sliding unit 5041 and the second sliding unit 5042 is achieved through the sliding match between the slide rails and the roller 5047. More preferably, as shown in the figure, the roller 5048 is connected to the bottom surface of the groove, allowing the roller 5047 to directly abut against the side wall of the second sliding unit 5042.

[0063] In a preferred embodiment, the first sliding unit 5041 is a plate structure (i.e., a mother rail plate), and the second sliding unit 5042 is also correspondingly configured as a plate structure (i.e., a daughter rail plate). Two folded edges are formed on both sides of the mother rail plate (first folded edge and second folded edge sequentially from the main body outwards), creating a cross-section resembling a "T"-shaped groove. Correspondingly, a folded edge (third folded edge) is formed on both sides of the daughter rail plate, so that the side walls of the daughter rail plate are directly opposite the inner wall of the "T"-shaped groove of the mother rail plate. Further, mounting holes are provided on both sides of the main body of the mother rail plate and on the second folded edges, with the mounting holes on the main body and the second folded edges aligned. Multiple mounting holes are spaced apart along a first direction. Correspondingly, rollers 5048 are embedded in the mounting holes, and the rollers 5048 are riveted to the mother rail plate with an interference fit. Rollers 5047 are fitted onto the rollers 5048, and the rollers 5047 slide and match the third folded edge on the daughter rail plate. More preferably, the width of the sub-rail plate is 40mm, and there is a gap of 0.1~0.2mm between the roller 5047 and the sub-rail plate.

[0064] Furthermore, the cable tracking device also includes a first base 3 and a second base 4. One end of the first base 3 is fixedly connected to the tail end of the chassis 2, and the other end is rotatably connected to the cable tracking unit. One end of the second base 4 is fixedly connected to the cabinet 1, and the other end is rotatably connected to the cable tracking unit.

[0065] Furthermore, multiple tracking units can be provided between the first tracking unit 501 and the second tracking unit 502, and the elastic mechanism 504 is connected to the first tracking unit 501 and the second tracking unit 502 respectively. Alternatively, multiple tracking units can be sequentially provided at the end of the second tracking unit 502 away from the first tracking unit 501, and elastic mechanisms 504 can be provided corresponding to these tracking units, with one elastic mechanism 504 configured for every two tracking units. More preferably, the two connecting ends of the elastic mechanism 504 are respectively connected to the ends of the two tracking units away from each other to maintain the stability between the two tracking units.

[0066] Furthermore, the connecting ends of the first sliding unit 5041 and / or the second sliding unit 5042 may form two rotatable connection positions. For example, a third tracking unit 503 is provided at one end of the second tracking unit 502 away from the first tracking unit 501. The third tracking unit 503 can be rotatably connected to the connecting end, thereby realizing the rotatable connection between the third tracking unit 503 and the second tracking unit 502.

[0067] Furthermore, the cable-following unit is a plate structure with cable mounting holes 505 arranged in an array on it, which can be used to install cables. Adjacent cable-following units or cable-following units and elastic mechanisms 504 are hinged by hinge pins.

[0068] In one embodiment, the first wiring unit 501 is rotatably connected to the second wiring unit 502 and is configured with an elastic structure. One end of the elastic mechanism 504 is also rotatably connected to the third wiring unit 503. One end of the first wiring unit 501 is rotatably connected to the chassis 2, and one end of the third wiring unit 503 is rotatably connected to the cabinet 1.

[0069] Furthermore, when chassis 2 is pulled out of cabinet 1, chassis 2 and cabinet 1 rotate relative to each other through the third cable-following unit 503 and the elastic mechanism 504, and rotate to the limit. At this time, chassis 2 continues to be pulled outward, the elastic structure begins to elongate, and then the first cable-following unit 501 and the second cable-following unit 502 also elongate, until the elastic mechanism 504 is stretched to the limit. At this time, chassis 2 is pulled out of cabinet 1 as a whole, and the cable-following device is in the unfolded state, which also realizes the cable-following operation of the tail cable of chassis 2.

[0070] Furthermore, when the chassis 2 is inserted inward, the elastic mechanism 504 begins to shorten under the pulling force of the elastic element 5044, which in turn drives the first cable-following unit 501 and the second cable-following unit 502 to fold and store until the elastic mechanism 504 returns to its original state. After that, the elastic mechanism 504 and the third cable-following unit 503 continue to rotate until the chassis 2 is fully inserted into the cabinet 1. At this time, the cable-following device is in a folded and stored state.

[0071] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
