Description

Technical Field

[0001] This invention relates to the field of cable tray technology, and more specifically, to an anti-winding cable tray with an internal branching structure. Background Technology

[0002] Cable trays (a concept derived from cable) are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories.

[0003] During use, cables are laid in cable trays and supported by the cable trays. Under normal circumstances, the cables in the cable trays do not interfere with each other. Moreover, the cable routing is already installed and the cables are arranged during installation. Therefore, when there is no external influence, the cables in the cable trays are relatively neat and there is no possibility of tangling.

[0004] However, later on, the cable tray cover may be opened to repair the cables. At this time, the cables will be pulled out, which will disrupt the initial state. Moreover, it is difficult to restore the pulled-out cables. Therefore, there will be more pulled-out cables than in the initial state, and the cables will become tangled.

[0005] In the prior art, Chinese patent application number CN202121082859.3 discloses a cable tray with a branching function, including a cable tray with a vertical mounting groove on the inner side wall of the cable tray. A cable limiting mechanism is installed inside the vertical mounting groove. Branching mechanisms are installed on both sides of the cable limiting mechanism inside the cable tray. Cable clips are installed on the upper surface of the branching mechanism to clip the cable into the inside of the cable clips, which facilitates subsequent wiring operations and ensures that the cable will not be tangled, thus ensuring the neat distribution of cables inside the cable tray.

[0006] Although existing technologies include cable splitting, this clamping method restricts cable movement, making cable repair inconvenient. Even if the cable is forcibly pulled out despite the damage, it is difficult to restore the cable to its original state after repair. Therefore, there is still extra cable compared to the initial state. After multiple repairs, the amount of extra cable will increase, leading to the risk of cables becoming tangled.

[0007] Moreover, existing cable installation techniques require clamping or limiting before the cable can be laid in the cable tray, which makes cable laying more difficult.

[0008] Therefore, there is an urgent need to propose a cable tray with an internal branching structure to prevent tangling. Summary of the Invention

[0009] The purpose of this invention is to provide an anti-tangle cable tray with an internal branching structure to solve the problem mentioned in the background art, namely: the clamping method restricts the movement of cables.

[0010] To achieve the above objectives, a cable tray with an internal branching structure and designed to prevent tangling is provided. It includes a support body with wiring channels and a cover on top of the support body. The wiring channels are used for laying cables. A lifting member is provided within the wiring channels of the support body, lifting the corresponding cable within the wiring channels.

[0011] One of the lifting members corresponds to one wire body, so as to branch the wire body in the wiring channel under the support of the lifting member.

[0012] The cable is lifted by the jacking mechanism. After both ends of the cable are fixed, the lifted cable becomes taut, preventing it from deviating from the laying path. This also serves as a cable splitter and avoids the cables from tangling. Most importantly, there are no extra restrictions during installation. The cable can be placed or passed through the wiring trough in the normal way. Moreover, the jacking mechanism only supports one side of the cable. That is to say, the cable can only be restricted by the support of the jacking mechanism if both ends are fixed. Therefore, the cable can move quite flexibly on the jacking mechanism when both ends are not fixed.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In this anti-tangle cable tray with built-in branching structure, the cable body can move quite flexibly on the lifting component even when the two ends of the cable body are not fixed, thus solving the problem that the clamping method would restrict the movement of the cable. Moreover, no excessive operation steps are required for installation or maintenance, thereby reducing the difficulty of laying.

[0015] 2. In this cable tray with an internal branching structure, the active body disengages from the through slot by rotating with the adapter seat. In other words, the support surface is no longer inside the wiring slot, and the through slot is exposed. At this time, the through slot can be used to form a space for maintenance docking. This eliminates the need to disassemble the cover for maintenance, greatly improving maintenance efficiency.

[0016] 3. In this cable tray with an internal branching structure, the support surface lifts the connecting end upwards, changing the direction of the cable. Since the shortest distance between two points is a straight line, it is no longer a straight line once the direction is changed. Therefore, the support surface also increases the length of the cable remaining in the through groove. This way, after the body rotates, the connecting end can hang down under the action of gravity, so there is no need to deliberately pull out the connecting end, making maintenance more convenient.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Cable trays (a concept derived from cable) are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories.

[0038] During use, cables are laid in cable trays and supported by the cable trays. Under normal circumstances, the cables in the cable trays do not interfere with each other. Moreover, the cable routing is already installed and the cables are arranged during installation. Therefore, when there is no external influence, the cables in the cable trays are relatively neat and there is no possibility of tangling.

[0039] Therefore, the present invention provides an anti-tangle cable tray with an internal branching structure, such as... Figure 1 As shown, the cable tray includes a support body 100 with a wiring groove, and a cover 200 is provided on the top of the support body 100. The wiring groove is hollowed out on the top of the support body 100. The cover 200 is used to seal the hollowed-out part on the top of the support body 100. Then the cable 300 is laid in the wiring groove. It can be seen that the above structure is the basic structure of the cable tray for laying cables.

[0040] Based on this, the present invention addresses the problem (i.e., the problem that the clamping method restricts cable movement) by disclosing a lifting member 400, such as... Figure 2 As shown, a lifting member 400 is provided in the wiring groove of the support body 100. The lifting member 400 lifts the corresponding wire 300, and one lifting member 400 corresponds to one wire 300, so as to split the wires 300 in the wiring groove.

[0041] In use, multiple lifting members 400 are arranged horizontally in the wiring trough, and one lifting member 400 corresponds to the laying route of one cable 300. Therefore, the laid cable 300 has only one layer in the wiring trough, making multi-layer stacking impossible. To reduce the space occupied by the support body 100, it is often designed to be flat, as long as the wiring trough inside can accommodate the lifted cable 300 after the cover body 200 is closed. However, in actual installation, multi-layer setup of the cable 300 along the same route can be achieved by stacking the support bodies 100 after the cover body 200 is closed, thus saving space. The cable 300 is laid directly corresponding to the lifting member 400; that is, the cable 300 is placed directly on or passes through the path of the lifting member 400, and then the lifting member 400 actively lifts the cable 300, fixing it at both ends. Once positioned, the lifted cable 300 becomes taut, preventing it from deviating from the laying path. This serves as a cable splitter and prevents the cables from tangling. Most importantly, cable 300 installation is straightforward; it can be placed or passed through the wiring trough as normal. The lifting component 400 only supports one side of the cable 300, meaning it only provides support when both ends are secured. Therefore, the cable 300 moves freely on the lifting component 400 when both ends are not secured, solving the problem of clamping restricting cable movement. Furthermore, installation and maintenance require minimal steps, reducing the difficulty of laying cables.

[0042] Combination Figure 3 As shown, in order to improve the ventilation in the wiring trough, ventilation holes 100B are often opened on the support 100.

[0043] The specific implementation methods are illustrated through the following examples:

[0044] First embodiment, see continue reading Figure 2 As shown, in order to achieve the hollowing out of the top of the wiring trough, the cross-section of the support body 100 is set into a "U" shape, and the bottom wall of the support body 100 is horizontal to ensure that the wire 300 is laid on a horizontal surface. In this way, the wire 300 will not stack together due to gravity. The ventilation hole 100B is opened on the side wall of the support body 100. The lifting member 400 is fixed above the bottom wall of the support body 100, and the top of the lifting member 400 has an upward protruding support surface. The support surface is preferably an arc-shaped plane, but it can also be a folded plane, etc. However, the arc-shaped plane has a smoother transition and causes less damage to the wire 300.

[0045] Second embodiment, see below. Figure 2 As shown, in this embodiment, the lifting member 400 is detachably fixed above the bottom wall of the support body 100. Specifically, the lifting member 400 is fixed by bolts or other screw-in and nail-in parts. Similarly, the top of the lifting member 400 has an upwardly protruding support surface.

[0046] In the first and second embodiments, the lifting member 400 exists in the wiring groove before the wire body 300 is laid. If the lifting member 400 is integrally formed with the support body 100, it is not necessary to install the lifting member 400 in advance. Otherwise, the lifting member 400 is installed on the bottom wall of the support body 100 at a designated position (a screw hole is pre-drilled at the designated position) by bolts. Then the wire body 300 is laid in the wiring groove corresponding to the lifting member 400. After the two ends of the wire body 300 are fixed, the cover body 200 can be covered. In this way, the whole operation is completed.

[0047] The third embodiment, such as Figure 3 As shown, in this embodiment, a through groove 100A is formed on the bottom wall of the support body 100 along the laying path of the wire body 300. The lifting member 400 is installed below the bottom wall of the support body 100. Then, the support surface enters the wiring groove through the through groove 100A by rotating. Figure 4 In the middle, the lifting member 400 includes an adapter 410 and an action body 420. The action body 420 is an arc-shaped plate structure, thereby forming an upwardly protruding support surface. Two connecting ends are formed on both sides of the action body 420. One connecting end is rotatably connected to the adapter 410, and the other connecting end is used to connect to the bottom wall of the support body 100. The adapter 410 is also fixed on the bottom wall of the support body 100. With the adapter 410 and the connecting end fixed, the action body 420 can span the through groove 100A and make the support surface exist in the wiring groove. That is to say, the support surface enters the wiring groove after the wire body 300 is laid.

[0048] Specifically, the adapter 410 is connected to the bottom wall of the support 100 on one side of the through groove 100A by bolts or other screw-in parts and nails, while the connecting end of the action body 420 is connected to the bottom wall of the support 100 on the other side of the through groove 100A by bolts or other screw-in parts and nails.

[0049] In the second and third embodiments, the lifting member 400 can be set according to the docking end 300a of the line 300. The docking end 300a refers to the docking point of two lines 300 merged into one. Because the docking point in the line 300 is relatively weak, it is easily damaged and requires frequent maintenance. Therefore, it can be protected by a support surface to reduce the maintenance frequency. The specific protection principle is as follows:

[0050] like Figure 5 As shown, when tension occurs at both ends of the line body 300, the docking end 300a is positioned at the highest point of the support surface, thus hindering the movement of the docking end 300a under the constraint of the support surface; as Figure 6 As shown, if only one end is pulled, the docking end 300a will fall on the lower side of the support surface, specifically the lower side relative to the direction of pulling. This will better hinder the movement of the docking end 300a, thereby preventing the docking end 300a from being damaged during movement.

[0051] Especially in the third embodiment, such as Figure 5 As shown, after the supporting surface lifts the mating end 300a, since the actuating body 420 is a plate-like structure, a ventilation channel is formed between it and the through slot 100A. This accelerates the airflow around the mating end 300a, improves heat dissipation efficiency, and solves the problem of high heat at the mating end 300a (because the temperature of the mating end 300a after mating will increase due to the winding between the wire cores, causing current to pass through). Moreover, for maintenance at the mating end 300a, the bolts at the connecting end can be unscrewed, and then the actuating body 420 will disengage from the through slot 100A by rotating with the adapter 410 (i.e., Figure 5 The direction of rotation is indicated by the dashed arrow in the middle, meaning that the support surface no longer exists within the wiring groove (the specific location of the support surface is as follows). Figure 5 (As shown by the dotted line in the middle), and then the through groove 100A is exposed. At this time, the space of the maintenance docking end 300a can be formed by the through groove 100A, so that the cover 200 does not need to be disassembled for maintenance, which greatly improves the efficiency of maintenance.

[0052] Furthermore, the support surface lifts the docking end 300a upwards, changing the direction of the line 300. Since the shortest distance between two points is a straight line, the line is no longer straight once its direction is changed. Therefore, the support surface also increases the length of the line 300 within the through groove 100A. This way, after the actuator 420 rotates, the docking end 300a can hang down under the influence of gravity, eliminating the need to deliberately pull out the docking end 300a. This makes maintenance more convenient and avoids unnecessary damage caused by pulling the line 300.

[0053] In addition, when laying the cable 300, the actuator 420 is not in the wiring trough, which reduces the interference caused by the actuator 420 to the laying of the cable 300. After the cable 300 is laid, the actuator 420 is rotated directly to fix the connecting end to the bottom wall of the support 100, so that the cable 300 can be actively lifted by the support surface.

[0054] In the second and third embodiments, the lifting member 400 can be added later according to the number and location of the docking ends 300a.

[0055] In addition, to improve the restraining strength of the support surface on the line body 300, a restraining groove 420A is provided on the support surface. See details. Figure 4 As shown, in the third embodiment, the limiting groove 420A is formed on the action body 420.

[0056] The following improvements are made based on the third embodiment:

[0057] Please participate Figure 6 As shown, the adapter 410 is provided with a resistance block 411. After the connection end of the action body 420 is released from fixation, the rotating action body 420 is blocked by the resistance block 411, and then the support surface of the action body 420 forms a horizontal support platform 421, which facilitates the placement of some maintenance equipment connected to the docking end 300a.

[0058] The fourth embodiment discloses another implementation of the action body 420 based on the third embodiment. Please refer to [link to third embodiment]. Figure 7 As shown, in this embodiment, the action body 420 is a frame structure. Within the action body 420, there is a tail-side action plate 420a and a head-side action plate 420b. The tail-side action plate 420a and the head-side action plate 420b are rotatably connected to the action body 420 in a split manner. An elastic element, such as a torsion spring or an elastic plate, is provided at the rotatable connection point, causing the tail-side action plate 420a and the head-side action plate 420b to flip outwards. Then, the tail-side action plate 420a and the head-side action plate 420b together form a support surface. The length of the support line 300 is determined by the pressure of the tail side action plate 420a and the head side action plate 420b. The greater the downward pressure, the greater the angle of rotation of the tail side action plate 420a and the head side action plate 420b under pressure. At this time, the length of the support surface formed by the tail side action plate 420a and the head side action plate 420b is smaller. Conversely, the smaller the downward pressure, the greater the length of the support surface formed by the tail side action plate 420a and the head side action plate 420b. In this way, the length of the support line 300 becomes controllable.

[0059] It cannot be ruled out that the lifting member 400, in conjunction with other limiting structures, can improve the stability of the limiting line 300. To disclose the limiting structure, fifth and sixth embodiments were developed, in which:

[0060] For the fifth embodiment, please refer to... Figure 8 As shown, the lifting member 400 is provided with a limiting body 422. Specifically, the limiting body 422 is set on the support surface, and the limiting body 422 itself has a certain elasticity. Then, two limiting bodies 422 are set on both sides of the line body 300 to clamp it, thereby improving the stability of the line body 300 connected to the support surface.

[0061] For the sixth embodiment, please refer to... Figure 9 As shown, the bolts on the adapter 410 and the connecting end connected to the bottom wall of the support 100 extend into the wiring groove, and then the bolts restrict both sides of the wire 300. Then, the restrictor 422 is inserted. In this embodiment, the restrictor 422 is a separate plate structure. After inserting the restrictor 422, the nut is screwed on to stably connect the wire 300 to the support surface through the restrictor 422.

[0062] Finally, while the cover 200 commonly seen in all the above embodiments is a long plate, this invention also discloses another type of cover 200, please refer to [link / reference needed]. Figure 10 As shown, the cover 200 is composed of multiple short plates. There are locking posts on both sides of the short plates. The side wall of the support body 100 is provided with oblique guide grooves 100C and right-angle guide grooves 100D corresponding to the locking posts. The locking posts are inserted into the corresponding oblique guide grooves 100C and right-angle guide grooves 100D in sequence. The wiring channel is sealed by multiple short plates. Finally, the gap between two adjacent short plates is sealed by the filling plate 210. In this way, the short plates can be disassembled in a targeted manner, instead of disassembling a whole piece, which is inconvenient for both disassembly and installation.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
