Description

Technical Field

[0001] This utility model relates to the field of power equipment installation equipment, and in particular to a power installation bracket. Background Technology

[0002] When installing electrical equipment, auxiliary equipment is usually used to assist in the installation. For example, when installing electrical equipment such as cables on a building, a cable tray is first installed on the wall surface, then the cable is placed in the cable tray, and finally the tray cover is closed to seal the cable, thereby isolating the cable from people in the building, preventing the cable from being touched by people, and reducing the risk of injury to people caused by cable leakage.

[0003] In factories, cable laying may be changed according to production plans, requiring the addition or replacement of cables on the existing lines. When replacing cables, they are usually pulled directly out of the cable trays. During this process, the cables may move the cable trays, making the connection between the cable trays and the walls less stable, leading to displacement or even detachment of the cable trays. Utility Model Content

[0004] The purpose of this utility model is to provide a power installation bracket to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this utility model is:

[0006] A power installation bracket, comprising:

[0007] The frame has an installation side on one side, and the frame has an installation groove. The groove opening is parallel to the horizontal direction and away from the installation side.

[0008] A cable tray is installed at the mounting slot, and a connector is installed on the frame, the connector passing through the frame and the cable tray and protruding from the mounting side.

[0009] This technical solution has at least the following beneficial effects: Before installing cables in the factory, a predetermined number of frames are first installed on the walls of the factory or other buildings according to the production plan. Then, the cable trays are placed into the installation slots of each frame. Finally, connectors are inserted into the frames and cable trays, with one end of the connector protruding from the installation side and entering the wall at the frame installation location. This design supports the cable trays through the frames and restricts the vertical movement of the cable trays through the installation slots. The connectors then connect the frames, cable trays, and walls, restricting the movement of the cable trays away from the installation side. This reduces the possibility of the cable trays being moved by the cables when workers pull the cables inside the cable trays, thus improving the stability of the cable trays after installation.

[0010] As a further improvement to the above technical solution, the connector includes a threaded rod that extends vertically and connects to the cable tray and the frame. The threaded structure of the threaded rod provides better fastening force and stability, ensuring a stable connection between the cable tray and the frame.

[0011] As a further improvement to the above technical solution, the cable tray includes a tray body and a tray cover. The tray body is installed at the mounting slot, and the threaded rod is connected to the tray body. The tray body has an opening, which is in the same direction as the slot opening. The tray cover is placed at the opening. By splitting the cable tray into a tray body and a tray cover, it can be ensured that the tray body is sealed by the tray cover during normal use to prevent dust, moisture, etc. from entering the tray body and affecting the cable. At the same time, the tray cover can be removed when needed to perform partial inspection of the cable, thus meeting the requirements of daily maintenance of electrical equipment.

[0012] As a further improvement to the above technical solution, the slot cover is elastically connected with a snap-fit ​​strip, and the slot body is provided with a snap-fit ​​groove on the inner side wall at the opening. The snap-fit ​​strip snaps into the snap-fit ​​groove, and the quick connection between the slot cover and the slot body is realized through the snap-fit ​​strip. When disassembling, the snap-fit ​​strip can also be dislodged from the snap-fit ​​groove by appropriate tools or operations, which facilitates the maintenance of the cable.

[0013] As a further improvement to the above technical solution, a first guide surface is provided on the side of the snap-fit ​​strip near the snap-fit ​​groove. The first guide surface is inclined away from the snap-fit ​​groove and abuts against the groove body. When installing the groove cover, the first guide surface contacts the groove body first, which plays a guiding and buffering role, so that the snap-fit ​​strip can slide into the snap-fit ​​groove more smoothly, reducing the resistance during snap-fit ​​and the wear between components, improving the convenience of groove cover installation and the service life of components.

[0014] As a further improvement to the above technical solution, the bottom of the snap-fit ​​groove is provided with a first sliding groove in the vertical direction, a locking rod is installed at the first sliding groove, the groove body is provided with a driving member for driving the locking rod to move towards or away from the snap-fit ​​bar, and the snap-fit ​​bar is provided with a locking groove for the locking rod to be inserted after sliding.

[0015] By adopting the above scheme, after the snap-fit ​​strip enters the snap-fit ​​groove, the locking rod is driven by the driving component to slide from the first slide groove toward the snap-fit ​​strip and enter the locking groove, thereby locking the snap-fit ​​strip located in the snap-fit ​​groove. This achieves secondary locking of the snap-fit ​​strip, greatly improving the stability of the connection between the groove cover and the groove body. This ensures that the groove cover maintains a stable connection with the groove body in complex factory environments such as when subjected to vibration or impact, thus guaranteeing the safe laying and stable operation of cables.

[0016] As a further improvement to the above technical solution, the driving component includes a driving rod, the groove body has a driving groove extending in the horizontal direction, the groove has a first connecting hole for the threaded rod to pass through, the driving groove is connected to the first sliding groove and the first connecting hole respectively, the driving rod is slidably installed in the driving groove, the locking rod has a second guide surface at the lower end, the second guide surface is inclined upward, one end of the driving rod abuts against the second guide surface, and the other end has a third guide surface at the lower side, the third guide surface is inclined upward, and the third guide surface abuts against the threaded rod.

[0017] By adopting the above solution, after the slot cover is installed on the slot body, the installer needs to connect the threaded rod to the frame and the slot. After inserting the threaded rod into the frame body, the threaded rod drives the drive rod to move away from the threaded rod through the action of the third guide surface. Then, through the action of the second guide surface, the drive rod drives the locking rod to move from the first slide groove towards the snap-fit ​​strip and lock the snap-fit ​​strip. This design utilizes the threaded rod, which plays a connecting role, to complete the stable connection between the slot body and the frame body, while locking the snap-fit ​​strip in the snap-fit ​​groove through the linkage of the drive rod. There is no need to use other power structures to drive the locking rod, thereby improving the operational convenience of the entire frame during installation.

[0018] As a further improvement to the above technical solution, a fixing groove is provided on the frame along the vertical direction, and a fixing rod is installed on the frame at the fixing groove. A driving member is provided on the frame to drive the fixing rod to slide on the frame. After the fixing rod slides, it abuts against the side of the groove cover away from the groove body. After the wire trough is installed, the driving member is used to drive the fixing rod to slide. When the fixing rod slides onto the groove cover, pressure is applied to the entire wire trough, thereby stabilizing the wire trough in the installation groove and reducing the possibility of the wire trough coming off the frame. Then the groove cover is pressed onto the groove body. When the cable inside the wire trough presses the groove cover from the inside, pressure is applied from the outside to balance the pressure of the cable on the groove cover, reducing the possibility of the groove cover being pushed out of the groove body by the cable.

[0019] As a further improvement to the above technical solution, the frame is provided with a second connecting hole for the threaded rod to pass through. The driving component includes a first airbag, a second airbag, and a driving rod. The first airbag is installed in the fixing groove and is located between the fixing rod and the frame. The frame is provided with a driving groove extending in a horizontal direction and communicating with the second connecting hole. The driving rod is slidably installed in the driving groove. A fourth guide surface is provided on the side of the driving rod facing downward toward the second connecting hole. The fourth guide surface is inclined upward and the threaded rod abuts against the fourth guide surface. The second airbag is installed in the driving groove and is located between the driving rod and the frame. The first airbag and the second airbag are connected by an air tube.

[0020] By adopting the above technical solution, when the threaded rod continues to be used, the threaded rod will abut against the fourth guide surface on the driving rod, thereby driving the driving rod to move away from the threaded rod, thus compressing the first airbag. After the first airbag is compressed, the gas is transmitted to the second airbag through the air tube, thereby causing the second airbag to expand between the driving rod and the frame, thereby moving the driving rod closer to the end cover and abutting against the end cover. This solution utilizes the threaded rod as a connector. While the threaded rod connects the frame and the wire trough, it also serves as a power source. Through the linkage of the first airbag, the second airbag, and the driving rod, the fixing rod is driven to lock the entire wire trough in the mounting groove, reducing the possibility of the wire trough detaching from the mounting groove.

[0021] As a further improvement to the above technical solution, the frame includes a horizontal frame and a vertical frame. The vertical frame extends vertically on the side away from the mounting side. A pair of horizontal frames are arranged vertically. One end of the two horizontal frames is connected to the vertical frame, and the other end extends in the direction away from the mounting side. The mounting groove is formed between the two horizontal frames. The second connecting hole is opened on the horizontal frame, and the threaded rod passes through the second connecting hole and is connected to the horizontal frame.

[0022] The cable tray is clamped by the mounting slot formed by the two crossbeams, which reduces the vertical displacement of the cable tray. At the same time, the crossbeams provide stable support for the cable tray, improving the practicality and reliability of the entire power installation bracket. Attached Figure Description

[0035] In the factory, the laying of cables may be changed according to the production plan, requiring the addition or replacement of cables on the original line. When replacing cables, the cable is usually pulled directly out of the cable tray 2. During this process, the cable may move the cable tray 2, making the connection between the cable tray 2 and the wall unstable, causing the cable tray 2 to shift or even fall off, resulting in an accident.

[0036] Therefore, in order to improve the stability of the connection between the cable tray 2 and the wall, this application provides an electrical installation bracket.

[0037] Reference Figure 1 An electrical installation bracket includes:

[0038] The frame 1 has one side as the mounting side. In this embodiment, the frame 1 is installed on the wall of the factory. The frame 1 has a mounting groove 11. The groove of the mounting groove 11 is parallel to the horizontal direction and away from the mounting side. The frame 1 is provided with a stabilizing member for stably connecting the frame 1 to the wall.

[0039] The stabilizing component may be an expansion bolt or a bolt. In this embodiment, the wall is made of concrete, and a sleeve is pre-embedded in the wall. The stabilizing component is a bolt, and the sleeve is provided with an internal thread. The bolt is connected to the frame 1 and protrudes from the installation side. The end of the bolt protruding from the installation side is threaded to the sleeve. Through the stable connection between the bolt and the sleeve, the frame 1 is stably installed on the wall.

[0040] As a further preferred embodiment, the frame 1 includes horizontal frames and vertical frames. The vertical frames are opposite to the mounting groove 11 and extend in the vertical direction. A pair of horizontal frames are arranged in the vertical direction. One end of the two horizontal frames is installed on the vertical frame, and the other side extends in the horizontal direction away from the mounting side. The space between the two horizontal frames forms the mounting groove 11. Through the horizontal frames, stable support is provided for the cable from below, which improves the practicality and reliability of the entire power installation bracket.

[0041] Cable trough 2 is installed at mounting slot 11. A connector is installed on the frame 1. The connector passes through the frame 1 and cable trough 2 and protrudes from the mounting side. The part of the connector protruding from the mounting slot 11 is connected to the wall. At this time, the connector connects cable trough 2 and frame 1 together. Then, the two are fixed to the wall, which further improves the connection stability between cable trough 2, frame 1 and the wall, thereby providing stable support for the cables in the factory.

[0042] In this embodiment, multiple frame bodies 1 are arranged horizontally on the wall, with each frame body 1 on the same horizontal line. The cable tray 2 extends along the arrangement direction of the frame bodies 1. Before installation, a predetermined number of frame bodies 1 are installed on the wall according to the production plan. Then, the cable tray 2 is placed into the installation slot 11 of each frame body 1. Finally, a connector is inserted into the frame body 1 and the cable tray 2. One end of the connector protrudes from the installation side and enters the wall at the installation location of the frame body 1. By adopting the design of frame bodies 1 and cable tray 2, the cable tray 2, frame body 1 and wall are connected by the connector. This limits the possibility of the cable pulling the cable tray 2 when the worker pulls the cable in the cable tray 2, thereby improving the stability of the cable tray 2 after installation.

[0043] Reference Figure 1 and Figure 2 The connector includes a threaded rod 3. The wire groove 2 has a first connecting hole for the threaded rod 3 to pass through. Each cross frame has a second connecting hole for the threaded rod 3 to pass through. The threaded rod 3 extends vertically. The threaded rod 3 is connected to the wire groove 2 through the first connecting hole. The threaded rod 3 is connected to the cross frame through the second connecting hole. One end of the threaded rod 3 that passes through the cross frame is connected to the wall at the top of the frame 1.

[0044] As a further preferred embodiment, in this embodiment, both the first connecting hole and the second connecting hole are provided with internal threads. The threaded rod 3 is threadedly connected to the wire groove 2 and the frame 1. One end of the threaded rod 3 that extends out of the installation side enters the wall and is threadedly connected to the wall. Through the meshing between the threads, the threaded rod 3 and the frame 1 are stably connected.

[0045] Further, as a preferred embodiment, refer to Figure 2 , Figure 3 and Figure 4 The cable tray 2 includes a tray body 21 and a tray cover 22. The tray body 21 has a C-shaped cross-section along the extension direction of the frame 1. The tray body 21 has a cavity for placing cables. A first connecting hole is opened on the tray body 21. The tray body 21 is installed at the mounting slot 11. A threaded rod 3 is connected to the tray body 21. The tray body 21 has an opening. The opening is in the same direction as the slot opening and is connected to the cavity. The tray cover 22 is placed at the opening position. A snap-fit ​​strip 23 extending along the arrangement direction of the frame 1 is elastically connected to the tray cover 22. The inner walls of the upper and lower sides of the tray body 21 are provided with snap-fit ​​grooves 26 extending along the arrangement direction of the frame 1. The snap-fit ​​strip 23 corresponds to the snap-fit ​​groove 26 one by one. The snap-fit ​​strip 23 snaps into the corresponding snap-fit ​​groove 26.

[0046] When installing the cable tray 2, first install the tray body 21 on the mounting slot 11 of the frame 1, and then snap the snap strip 23 of the tray cover 22 into the snap slot 26 of the tray body 21. In this embodiment, multiple tray covers 22 are provided on the same section of the tray body 21. When inspecting part of the cable, only one part of the tray cover 22 needs to be removed from the tray body 21 at that point to inspect that part of the cable. There is no need to remove the entire section of the tray cover 22 from the tray body 21, which reduces the workload of the electrician.

[0047] Reference Figure 4 Each snap-fit ​​strip 23 has a first guide surface on the side near the corresponding snap-fit ​​groove 26. The first guide surface is inclined away from the snap-fit ​​groove 26 and abuts against the groove body 21. When installing the groove 11 cover, the first guide surface on the snap-fit ​​strip 23 contacts the groove body 21 first, which plays a guiding and buffering role, so that the snap-fit ​​strip 23 can slide into the snap-fit ​​groove 26 more smoothly, reducing the resistance during snap-fit ​​and the wear between components, improving the convenience of installing the groove cover 22 and the service life of the components.

[0048] Reference Figure 3 and Figure 4 Each snap-fit ​​slot 26 has a first sliding groove extending vertically at the bottom of the slot. A locking rod 24 is slidably installed in the first sliding groove of the slot body 21. The slot body 21 is provided with a driving member for driving the locking rod 24 to slide closer to or away from the snap-fit ​​strip 23 corresponding to the snap-fit ​​slot 26. Each snap-fit ​​slot 26 is provided with a locking groove for the locking rod 24 on the corresponding snap-fit ​​slot 26 to be inserted. After the slot cover 22 is installed on the slot body 21, the driving member is activated to drive the locking rod 24 to slide closer to the snap-fit ​​slot 26. When the locking rod 24 slides into the locking groove, the locking rod 24 restricts the movement of the snap-fit ​​strip 23 in the horizontal direction, thereby reducing the risk of the slot cover 22 falling off due to the snap-fit ​​strip 23 sliding out of the snap-fit ​​slot 26.

[0049] The driving component includes a driving rod 25. A driving groove for the driving rod 25 to slide is provided in the groove 21. The driving groove extends horizontally and away from the mounting side. The first connecting hole is located on the side of the first sliding groove near the mounting side. One end of the driving groove is connected to the first sliding groove and the other end is connected to the first connecting hole. A second guide surface is provided on the side of the locking rod 24 facing downward and close to the mounting side. The second guide surface is inclined towards the mounting side. One end of the driving rod 25 passes through the first sliding groove and abuts against the second guide surface of the locking rod 24. The other end passes through the first connecting hole and abuts against the threaded rod 3. A third guide surface is provided on the side of the driving rod 25 that abuts against the threaded rod 3 and faces downward. The third guide surface is inclined upward. In this embodiment, the end of the driving rod 25 near the threaded rod 3 at the third guide surface is provided with an arc-shaped surface. The contact between the driving rod 25 and the threaded rod 3 by the arc-shaped surface improves the smoothness of the contact between the driving rod 25 and the threaded rod 3 and reduces the situation where the sharp end of the driving rod 25 gets stuck when it contacts the threaded rod 3, making it difficult to turn the threaded rod 3.

[0050] After the slot cover 22 is installed onto the slot body 21, the worker inserts the threaded rod 3 through the second connecting hole into the crossbeam. At this time, the threaded rod 3 abuts against the third guide surface on the drive rod 25, thereby driving the drive rod 25 to slide away from the threaded rod 3. When the drive rod 25 slides to abut against the second guide surface on the locking rod 24, under the action of the second guide surface, the locking rod 24 moves vertically towards the snap-fit ​​strip 23 near that location, and then inserts into the locking groove. Through the vertically extending locking rod 24, it cooperates with the snap-fit ​​groove 26 to restrict the movement of the snap-fit ​​strip 23, thereby reducing the movement of the slot cover 22 on the slot body 21 and improving the overall structural stability of the slot 2.

[0051] In other embodiments, reference is made to Figure 3 and Figure 5 A fixing groove is provided on the upper horizontal frame along the vertical direction, with the groove opening facing downward. A fixing rod 12 is slidably installed on the horizontal frame at the fixing groove along the vertical direction. A driving member is provided on the horizontal frame to drive the fixing rod 12 to slide downward on the horizontal frame. After the fixing rod 12 slides downward in the vertical direction, it abuts against the side of the groove cover 22 away from the groove body 21.

[0052] Through this design, firstly, after the cable tray 2 is installed, the driving mechanism drives the fixing rod 12 to slide. When the fixing rod 12 slides onto the cable tray cover 22, pressure is applied to the entire cable tray 2, thereby securing the cable tray 2 within the mounting groove 11 and reducing the possibility of the cable tray 2 detaching from the frame 1. Then, the cover 22 is pressed onto the groove body 21. When the cable inside the cable tray 2 presses against the cover 22 from the inside, external pressure is applied to balance the pressure from the cable on the cover 22, reducing the possibility of the cover 22 being pushed out of the groove body 21 by the cable. Secondly, the fixing rod 12 is then pressed onto the groove body 21. The fixing rod 12 is set in the upper crossbeam. When the worker uses the threaded rod 3 to insert the crossbeam and the trough 2 from below for fixation, the threaded rod 3 first drives the locking rod 24 to insert into the trough cover 22. While the trough body 21 is installed on the frame 1, the trough cover 22 is completely fixed on the trough body 21. Then, the trough cover 22 is pressed from the outside to reduce the obstruction of the sliding path of the fixing rod 12 when the trough cover 22 is not installed stably. This allows the fixing rod 12 to stably abut against the side of the trough cover 22 away from the trough body 21, thereby fixing the entire trough 2.

[0053] Reference Figure 5 The driving mechanism includes a first airbag 13, a second airbag 14, and a driving rod 15. The first airbag 13 is installed in a fixing groove in the upper crossbar. One side of the first airbag 13 is connected to the fixing rod 12, and the other side is connected to the frame 1. When the first airbag 13 inflates, it drives the fixing rod 12 to slide downwards in the vertical direction, approaching the groove cover 22 until it abuts against the side of the groove cover 22 away from the groove body 21. The frame 1 has a driving groove that extends horizontally and faces the installation side. The driving groove communicates with the first connecting hole. The groove 21 is located in the... The driving groove is provided with the driving rod 15, and the second airbag 14 is installed between the driving rod 15 and the bottom of the driving groove. The second airbag 14 is connected to the end of the driving rod 15 away from the threaded rod 3. When the second airbag 14 inflates, it causes the driving rod 15 to move closer to the threaded rod 3. When the second airbag 14 contracts, it drives the driving rod 15 to move away from the threaded rod 3 and retract into the driving groove. An air pipe is provided on the outside of the cross frame. The two ends of the air pipe pass through the cross frame and are respectively connected to the first airbag 13 and the second airbag 14.

[0054] A fourth guide surface is provided on the side of the driving rod 15 facing downward toward the second connecting hole. The fourth guide surface is inclined upward, and the threaded rod 3 abuts against the fourth guide surface. In this embodiment, an arc-shaped surface is provided on the end of the driving rod 15 near the threaded rod 3 at the fourth guide surface. The contact between the arc-shaped surface and the threaded rod 3 improves the smoothness of the contact between the driving rod 15 and the threaded rod 3, and reduces the situation where the threaded rod 3 is difficult to turn due to jamming when the sharp end contacts the threaded rod 3.

[0055] When the threaded rod 3 is used, it abuts against the fourth guide surface on the drive rod 15, thereby driving the drive rod 15 to move away from the threaded rod 3, thus compressing the first airbag 13. After being compressed, the first airbag 13 transmits gas to the second airbag 14 through the air tube, thereby causing the second airbag 14 to expand between the drive rod 15 and the frame 1, thereby moving the drive rod 15 towards the end cover and abutting against the end cover. This scheme utilizes the threaded rod 3 as a connector. While the threaded rod 3 connects the frame 1 and the wire groove 2, the threaded rod 3 is used as a power source. Through the linkage of the first airbag 13, the second airbag 14 and the drive rod 15, the fixing rod 12 is driven to lock the wire groove 2 as a whole in the mounting groove 11, reducing the possibility of the wire groove 2 detaching from the mounting groove 11.

[0056] In this embodiment, the crossbeam is also equipped with a reset member for driving the fixed rod 12 back into the crossbeam. When it is necessary to remove the wire groove 2 on the frame 1, the threaded rod 3 is first pulled out of the frame 1. At this time, the threaded rod 3 no longer abuts against the fourth guide surface on the driving rod 15. Under the action of the reset member, the fixed rod 12 is reset into the fixed groove and no longer limits the groove cover 22 and the groove body 21. The threaded rod 3 continues to move until it is completely pulled out of the wire groove 2 and the frame 1. At this time, the locking rod 24 slides downward in the vertical direction under its own weight. When the locking rod 24 slides back into the first sliding groove, it no longer locks the groove cover 22 on the groove body 21. The worker can use tools to remove the groove cover 22 from the groove body 21, and complete the separation of the groove body 21, the groove cover 22 and the frame 1.

[0057] The resetting component includes an elastic element, which is installed in the fixing groove and located between the fixing rod 12 and the crossbar. One end of the elastic element is connected to the fixing rod 12 and the other end is connected to the bottom of the fixing groove. The elastic element always drives the fixing rod 12 to slide towards the bottom of the fixing groove. At the same time, the retracted fixing rod 12 squeezes the first airbag 13 and transmits the gas through the air tube to the second airbag 14, reducing the obstruction of the first airbag 13 to the fixing rod 12.

[0058] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
