Description

Technical Field

[0001] This invention relates to the field of cable tray technology, specifically to a cable tray equipped with adjustable wiring components. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures. They are composed of supports, brackets, and installation accessories. Cable trays in buildings can be installed independently or laid on various building (structure) and pipe gallery supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance.

[0003] The existing cable trays have the following problems: 1. Cable trays usually lay cables inside the tray. Different types of cables piled together can easily accumulate heat and age prematurely; 2. It is impossible to clamp cables of different inner diameters. In addition, clamping will squeeze the cables, causing wear to the cable sheath. Summary of the Invention

[0004] The present invention provides a cable tray equipped with adjustable wiring components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable tray equipped with an adjustable wiring assembly, comprising a cable frame, wherein a sliding cover is slidably adapted to the top of the cable frame; A sealing mechanism for enclosing the outside of the cable rack, the sealing mechanism being disposed on the outside of the cable rack; An overlapping mechanism for replenishing and filling cables is provided inside the cable rack; A wiring mechanism for adjustable wiring of cables, the wiring mechanism being disposed inside the cable rack; The cable rack is internally fixed with a sturdy frame plate.

[0006] Preferably, the cable rack has an entry hole on its outer side, which is an opening for the wiring mechanism and the splicing mechanism to enter the cable rack. The sealing plate is used to seal the insertion hole.

[0007] Preferably, the overlapping structure includes a fixed rail, which is fixedly installed inside the cable rack. An external frame is slidably fitted inside the fixed rail, and wire clamps are inserted into the upper and lower sides of the inner cavity of the external frame. The wire clamp is used to limit and route thin cables.

[0008] Preferably, a double-mouth frame is fixedly connected to the outer side of the external frame, and a baffle is extruded and adapted to the top of the double-mouth frame. The top of the baffle is rotatably connected to a support seat through a fixed shaft, and the support seat is disposed inside the wiring mechanism.

[0009] Preferably, the wiring mechanism includes an internal frame, the top of the inner cavity of the internal frame is fixedly connected to the support seat, the internal frame is sleeved with the double-mouth frame, the internal frame is threadedly connected to a threaded rod, and a limit rotating plate is fixedly connected to the outer side of the threaded rod. A second magnetic block is fixedly connected to the inner side of the cable rack.

[0010] Preferably, spring telescopic rods are symmetrically connected to both sides of the fixed rail, and a spherical rod is fixedly connected to the end of the spring telescopic rod away from the fixed rail. The spherical rod passes through the outside of the fixed rail and extends into its interior. The fixed rail has an internal sliding adapter with a slider. The top of the slider is fixedly connected to the internal frame. Both ends of the slider are extruded and adapted to the spherical rod. The center of the slider is threadedly connected to the threaded rod.

[0011] Preferably, an adapter plate is rotatably mounted on the top of the internal frame. A first magnetic block and a connecting rope are fixedly connected to the outer side of the adapter plate. A rope loop is fixedly connected to the outer side of the connecting rope. An elastic strip is fixedly connected to the outer side of the rope loop. A snap-fit ​​sleeve is fixedly connected to the end of the elastic strip away from the rope loop. The interior of the snap-fit ​​sleeve is slidably adapted to the connecting rope. The first magnetic block and the second magnetic block have a repulsive relationship, so that the adapter plate can release the obstruction of the limiting adapter plate.

[0012] Preferably, the elastic strip is used to reset the connecting rope, and the side of the connecting rope away from the snap-fit ​​sleeve is fitted with a fixed support post. The fixed support post is fixedly connected to the top of the internal frame, and the outer side of the fixed support post is fixedly connected to the snap-fit ​​sleeve.

[0013] Preferably, a sleeve plate is fixedly installed on the top of the inner cavity of the internal frame, a friction protrusion is fixedly connected inside the sleeve plate, and a plug plate is fitted in the center of the inner cavity of the sleeve plate, wherein the outer side of the plug plate is squeezed and adapted to the friction protrusion.

[0014] Preferably, the bottom of the internal frame and the socket plate are both fitted with an electric telescopic rod, wherein the electric telescopic rod is divided into three sections, and the middle section is fixedly connected to the socket plate. The top of the electric telescopic rod is fixedly connected to a top connecting strip, and the bottom of the top connecting strip is fixedly connected to a return spring and a piston rod, and the bottom end of the return spring is fixedly connected to the top of the socket plate. The reset spring is used to reset the top connecting bar and the electric telescopic rod.

[0015] Preferably, a protective pad is fixedly connected to the bottom of the power strip, and filling air pads are symmetrically arranged at both ends of the protective pad. The filling air pads are fixedly installed at the bottom of the power strip, a groove is opened inside the power strip, and an air tube is fixedly connected to the top of the power strip. The top of the air tube is slidably adapted to the piston rod, the bottom end of the air tube is connected to the groove, and the bottom end of the groove is connected to the filling air cushion.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the center of the outer side of the slider coincides with the spherical rod, the spherical rod will be embedded in the slider. The center of the outer side of the slider has a spherical hole. At this time, the spherical rod will play a role in limiting the slider, and also play a role in positioning and pre-limiting the entire wiring mechanism.

[0017] 2. Under the repulsive force between the two magnetic blocks, the tensile force of the connecting rope, and the deflection of the adapter plate, the adapter plate no longer limits the limiting plate. This allows the operator to use external tools or manually rotate the threaded rod to make the bottom of the threaded rod fit against the bottom of the inner cavity of the fixed rail, thereby locking and fixing the entire wiring mechanism.

[0018] 3. Because the external rack has a relatively large internal space, it allows heat from the internal rack to be effectively dissipated, thus facilitating heat dissipation. Furthermore, the connection between the internal and external racks increases the stability and heat dissipation of the cabling components.

[0019] 4. The air tube is filled with gas, which eventually flows through the groove into the filling air pad. This fills the space between the power strip and the cable sleeve during the cable clamping process. It also provides comprehensive protection for the cable, preventing any gaps that could compromise stability. Attached Figure Description

[0035] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Please refer to Figures 1-2. The present invention provides a technical solution: as shown in Figures 1-3, 2-4, 3-5, 4-6, 5-7, and 5-8, including a cable rack, wherein the top of the cable rack is slidably fitted with a sliding cover; A sealing mechanism for enclosing the outside of the cable rack, the sealing mechanism being disposed on the outside of the cable rack; An overlapping mechanism for replenishing and filling cables is provided inside the cable rack; A wiring mechanism for adjustable wiring of cables, the wiring mechanism being disposed inside the cable rack; The cable rack is internally fixed with a sturdy frame plate.

[0037] The sealing mechanism includes an electric push rod, which is fixedly installed on the outside of the cable rack. The output end of the electric push rod is fixedly connected to a connector, and the end of the connector away from the electric push rod is fixedly connected to a sealing plate. The cable rack has an entry hole on its outer side, which is an opening for the wiring mechanism and the splicing mechanism to enter the cable rack. The sealing plate is used to seal the insertion hole.

[0038] The overlapping structure includes a fixed rail, which is fixedly installed inside the cable rack. An external frame is slidably fitted inside the fixed rail, and wire clamps are inserted into the upper and lower sides of the inner cavity of the external frame. The cable clamps are used for limiting and routing thin cables. By passing the external frame through the insertion hole, the double-mouth frame connected to the outside of the external frame presses against the partition plate, causing the partition plate to deflect upwards through the fixed shaft fixed inside the support seat. Ultimately, the double-mouth frame is inserted into the internal frame, at which point the external frame and internal frame are mated. The cable clamps inserted inside the external frame are used for routing and limiting thin cables. Because the external frame has a relatively large internal space, it allows heat to be effectively dissipated when it is difficult for heat to dissipate from the internal frame. Simultaneously, the mating of the internal and external frames increases the stability and heat dissipation of the wiring assembly.

[0039] A double-mouth frame is fixedly connected to the outer side of the external frame. A baffle plate is extruded and fitted to the top of the double-mouth frame. A support seat is rotatably connected to the top of the baffle plate through a fixed shaft. The support seat is located inside the wiring mechanism.

[0040] As shown in Figures 1, 2, 3, and 4, the cabling mechanism includes an internal frame. The top of the internal cavity of the internal frame is fixedly connected to the support seat. The internal frame is sleeved with the double-mouth frame. A threaded rod is threaded inside the internal frame, and a limit plate is fixedly connected to the outside of the threaded rod. A stabilizing plate is fixedly installed inside the cable rack, and the stabilizing plate is adapted to the end face of the internal frame, thereby serving to connect and stabilize several internal frames.

[0041] A second magnetic block is fixedly connected to the inner side of the cable rack; Spring telescopic rods are symmetrically connected to both sides of the fixed rail. A spherical rod is fixedly connected to the end of the spring telescopic rod away from the fixed rail. The spherical rod passes through the outside of the fixed rail and extends into its interior. The fixed rail has an internal sliding adapter with a slider. The top of the slider is fixedly connected to the internal frame, and both ends of the slider are press-fitted with the spherical rod. The center of the slider is threadedly connected to the threaded rod. Activating the electric push rod causes the connector connected to its output end to move the sealing plate outwards and away from the cable rack. At this time, the inlet hole on the outside of the cable rack opens, allowing the operator to slide the wiring mechanism along the fixed rail to the predetermined position. The wiring mechanism includes an internal frame, and the bottom of the internal frame is slidably connected to the fixed rail via a slider. Therefore, the slider moves along the fixed rail... As the guide rail moves inward, it initially compresses the spherical rod. The end of the spherical rod that contacts the slider is spherical. The compressed spherical rod will protrude outward from the guide rail and stretch the spring telescopic rod. The spring telescopic rod plays a role in resetting the spherical rod. With the compression and friction between the spherical rod and the slider, when the center of the outer side of the slider coincides with the spherical rod, the spherical rod will embed into the slider. The center of the outer side of the slider has a spherical hole. At this time, the spherical rod will play a role in limiting the slider and also in positioning and pre-limiting the entire wiring mechanism.

[0042] A connecting plate is rotatably mounted on the top of the internal frame. A first magnetic block and a connecting rope are fixedly connected to the outer side of the connecting plate. A rope loop is fixedly connected to the outer side of the connecting rope, and an elastic strip is fixedly connected to the outer side of the rope loop. A snap-fit ​​sleeve is fixedly connected to the end of the elastic strip away from the rope loop. The interior of the snap-fit ​​sleeve is slidably adapted to the connecting rope. When the wiring mechanism moves to the predetermined position, the distance between the second magnetic block and the first magnetic block will decrease. The first magnetic block is connected to the connecting plate, and the connecting plate is rotatably mounted on the internal frame. Therefore, the connecting plate will deflect counterclockwise under the repulsive force of the two magnetic blocks. In addition, a connecting rope is fixedly connected to the outer side of the connecting plate, and the connecting rope is on the same side as the first magnetic block. The other end of the connecting rope is connected to another connecting plate. The purpose of the two connecting plates is to limit the position of the limiting plate and prevent the rotation of the threaded rod.

[0043] The first magnetic block and the second magnetic block have a repulsive relationship, so that the adapter plate can release the obstruction of the limiting adapter plate. The elastic strip is used to reset the connecting rope. A fixed support is fitted to the side of the connecting rope away from the snap-fit ​​sleeve. The fixed support is fixedly connected to the top of the internal frame, and its outer side is fixedly connected to the snap-fit ​​sleeve. The connecting rope is fulcrumped by the fixed support and limited by the snap-fit ​​sleeve. A rope sleeve is fixedly connected to the outer side of the connecting rope, and the rope sleeve is connected to the snap-fit ​​sleeve via the elastic strip. The elastic strip resets the connecting rope when the distance between the two magnetic blocks is stretched and no repulsive force is generated.

[0044] Ultimately, due to the repulsive force between the two magnetic blocks, the tensile force of the connecting rope, and the deflection of the adapter plate, the adapter plate no longer limits the limiting plate. This allows the operator to use external tools or manually rotate the threaded rod to make the bottom of the threaded rod fit against the bottom of the inner cavity of the fixed rail, thereby locking and fixing the entire wiring mechanism.

[0045] As shown in Figures 1, 2, and 3, a cable sleeve plate is fixedly installed on the top of the inner cavity of the internal frame. Friction protrusions are fixedly connected inside the cable sleeve plate. A plug plate is fitted into the center of the inner cavity of the cable sleeve plate, and the outer side of the plug plate is pressed and fitted with the friction protrusions. A protective pad is fixedly connected to the bottom of the plug plate, which serves to protect the top of the cable. In addition, there are friction protrusions between the plug plate and the cable sleeve plate, and the function of the friction protrusions is to increase the friction between the two and prevent the plug plate from sliding down the cable sleeve plate automatically.

[0046] The bottom of both the internal frame and the cable tray is fitted with a power telescopic rod, which is divided into three sections. The middle section is fixedly connected to the cable tray. A top connecting strip is fixedly connected to the top of the power telescopic rod, and a return spring and a piston rod are fixedly connected to the bottom of the top connecting strip. The bottom end of the return spring is fixedly connected to the top of the cable tray. By placing a large cable into the space enclosed by the cable tray and the cable tray, if the outer diameter of the cable matches the space, the sliding cover is then used to seal the top of the cable tray. Once the equipment is assembled, but when the outer diameter of the cable is smaller than the space, the electric telescopic pole is activated. The electric telescopic pole has three sections: the bottom section is fixed, the middle section is connected to the power strip, and the top section is connected to the top connecting strip. The top connecting strip is fixedly connected to the power strip via a return spring. The return spring has a certain degree of toughness, so when the electric telescopic pole drives the middle section to move the power strip downwards, the power strip will squeeze the cable. At this time, the power strip and the cable sleeve will limit and fix the cable.

[0047] The return spring is used to reset the top connecting bar and the electric telescopic rod; A protective pad is fixedly connected to the bottom of the power strip, and symmetrical air cushions are arranged at both ends of the protective pad. The air cushions are fixedly installed at the bottom of the power strip. A groove is opened inside the power strip, and an air tube is fixedly connected to the top of the power strip. When the power strip comes into contact with the cable, the top section of the electric telescopic rod has moved upward to the top of the middle section. When the power strip is squeezed against the cable, the middle section of the electric telescopic rod moves downward with the top section, compressing the return spring. Then, the top connecting bar moves downward with the piston rod, which inserts into the air tube, which is filled with gas. Finally, the gas in the air tube enters the air cushion through the groove, thus filling the space left between the power strip and the cable during the compression and clamping process. At the same time, it also provides all-round protection for the cable, preventing the stability from being affected by the remaining space.

[0048] The top of the air tube slides into the piston rod, the bottom of the air tube is connected to the groove, and the bottom of the groove is connected to the filling air pad. The air tube, groove, and filling air pad are not completely filled; only 80% of their internal space is filled with gas. This is to prevent accidental activation of the electric telescopic rod or contraction due to vibration, which would cause the filling air pad to bulge outwards and unreasonably compress the cable.

[0049] In use, the invention works as follows: First, the electric push rod is activated, causing the connector connected to its output end to move outward along with the sealing plate, away from the cable rack. At this time, the inlet hole on the outside of the cable rack opens, and the operator can then slide the wiring mechanism along the fixed rail to the predetermined position. The wiring mechanism includes an inner frame, and the bottom of the inner frame is slidably connected to the fixed rail via a slider. Therefore, as the slider moves inward along the fixed rail, it initially compresses the spherical rod. The end of the spherical rod that contacts the slider is spherical, and the compressed spherical rod will protrude outward from the fixed rail and stretch the spring telescopic rod. The spring telescopic rod serves to reset the spherical rod. With the compression and friction between the spherical rod and the slider, when the center of the outer side of the slider coincides with the spherical rod, the spherical rod will embed into the slider. The center of the outer side of the slider has a spherical hole, at which point the spherical rod will limit the movement of the slider.

[0050] When the wiring mechanism moves to the predetermined position, the distance between the second magnetic block and the first magnetic block will decrease. The first magnetic block is connected to the adapter plate, which is rotatably mounted on the internal frame. Therefore, the adapter plate will deflect counterclockwise under the repulsive force of the two magnetic blocks. Finally, under the repulsive force between the two magnetic blocks, the tensile force of the connecting rope, and the deflection of the adapter plate, the adapter plate will no longer limit the limiting plate. This allows the operator to use external tools or manually rotate the threaded rod to make the bottom of the threaded rod press and fit against the bottom of the inner cavity of the fixed rail.

[0051] By passing the external frame through the inlet hole, the double-mouth frame connected to the outside of the external frame will squeeze the baffle plate, causing the baffle plate to deflect upward through the fixed shaft fixedly connected inside the support seat. Finally, the double-mouth frame will be inserted into the inner frame, and the external frame will dock with the inner frame. The wire clamp inserted inside the external frame is used for wiring and limiting the thin cable.

[0052] By placing a large cable into the space enclosed by the power strip and the cable tray, if the cable's outer diameter matches the space, the sliding cover seals the top of the cable rack, completing the assembly. However, if the cable's outer diameter is smaller than the space, the electric telescopic rod is activated. The electric telescopic rod has three sections: the bottom section is fixed, the middle section is connected to the power strip, and the top section is connected to the top connecting strip, which is fixedly connected to the power strip via a return spring. Therefore, when the electric telescopic rod drives the middle section to move the power strip downwards, the power strip will compress the cable. At this time, the power strip and the cable tray will limit and fix the cable. When the power strip comes into contact with the cable, the top section of the telescopic pole has already moved upward to the top of the middle section. When the power strip and the cable are squeezed together, the middle section of the telescopic pole moves downward along with the top section, compressing the return spring. Then, the top connecting bar moves downward along with the piston rod, which inserts into the air tube filled with gas. Finally, the gas in the air tube enters the filling air pad through the groove. Therefore, during the process of the cable being squeezed and clamped, the filling air pad fills the space left between the power strip and the cable sleeve, protecting the cable.

[0053] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
