Description

Technical Field

[0001] This utility model relates to the field of electrical cable trays, specifically an easily adjustable cable tray for electrical engineering. Background Technology

[0002] Cable trays in electrical engineering are open or closed structural systems used to support, protect and manage cables. They are widely used in cable laying in fields such as construction, industry, power, and communications. Cable trays are rigid structural systems composed of supports, brackets, and installation accessories to support and lay cables. Compared with traditional cable ducts or trunking, cable trays have the characteristics of open layout, flexible expansion and easy maintenance.

[0003] Currently, when cable trays are fixed at the bottom of stairs or inclined buildings, cables also need to be placed inside the inclined cable trays. However, during long-term use, the inclined cable trays may sink due to their own weight, causing the connection between the inclined and horizontal cable trays to loosen, resulting in gaps between the cable trays and reducing the overall stability of the cable trays. In addition, external moisture and dust can accelerate cable aging or corrode the metal components of the cable trays. Furthermore, cables placed in a bent position may have their internal insulation or conductors damaged due to excessively small bending angles, thus creating safety hazards. Therefore, to address the above problems, an easily adjustable cable tray for electrical engineering is proposed. Utility Model Content

[0028] The following is in conjunction with the appendix Figure 1 —5 provides further detailed information about this application.

[0029] This application discloses an easily adjustable cable tray for electrical engineering. (See also...) Figure 1 An easily adjustable cable tray for electrical engineering, comprising:

[0030] Horizontal cable tray 1 and inclined cable tray 2, with connecting pieces 3 provided on the surfaces of horizontal cable tray 1 and inclined cable tray 2 near each other;

[0031] Stabilizing component 4 is located at the bottom of the inclined cable tray 2;

[0032] Guide component 5 is disposed inside the horizontal cable tray 1 and the inclined cable tray 2;

[0033] Reference Figure 2 - Figure 3The stabilizing component 4 includes a triangular rod 41 fixedly installed on the right end face of the connecting piece 3. A support plate 42 is provided at the bottom of the inclined bridge 2. An inner groove 43 is formed inside the support plate 42, and a sliding plate 441 is slidably connected inside the inner groove 43. A second support plate 442 is fixedly connected to one end of the sliding plate 441 near the side wall of the inclined bridge 2. The end of the triangular rod 41 away from the connecting piece 3 is fitted and attached to the left end face of the first support plate 42. There are two second support plates 442, and the top ends of the two second support plates 442 are fitted and attached to the bottom end of the triangular rod 41. The surfaces of the second support plates 442 and the triangular rod 41 have corresponding openings. With compatible threaded holes, two support plates 442 can be fixedly connected by bolts, nuts, and triangular rods 41, thus ensuring a stable connection between support plate 42 and triangular rods 41. A threaded rod 45 is rotatably connected inside support plate 42. The left and right ends of sliding plate 441 extend to the outside of the left and right sides of support plate 42, respectively. The threaded rod 45 is threaded into the interior of sliding plate 441. Rotating the threaded rod 45 adjusts the position of sliding plate 441, causing it to move support plate 442, thus aligning the corresponding threaded holes of support plate 442 and triangular rod 41. The internal thread of support plate 42 is connected to threaded rod 46. A pressing plate 47 is slidably connected internally to support plate 42. One end of threaded rod 46, near the interior of support plate 42, is rotatably connected to the end face of pressing plate 47 away from the inclined cable tray 2. A rubber pad is fixedly connected to the end of pressing plate 47 away from threaded rod 46. The rubber pad fits and adheres to the end face of the inclined cable tray 2. By rotating the two threaded rods 46 back and forth, the two pressing plates 47 are pushed to abut against the front and rear end faces of the inclined cable tray 2, thereby further fixing support plate 42 to the surface of the inclined cable tray 2. A vertical rod 4 is fixedly installed inside the top of pressing plate 47. 81. A lower pressure plate 482 is slidably connected to the surface of the vertical rod 481. A pressure spring 483 is fixedly connected to the bottom end of the lower pressure plate 482. A vertical groove is opened inside the pressing plate 47. The vertical rod 481 is fixedly installed inside the vertical groove. The top end of the pressure spring 483 is fixedly connected to the bottom wall of the lower pressure plate 482. The bottom end of the pressure spring 483 is fixedly connected to the bottom wall of the vertical groove. The bottom end of the lower pressure plate 482 is adapted to fit against the top wall of the inclined bridge frame 2. The lower pressure plate 482 abuts against the top end of the inclined bridge frame 2, thereby limiting the pressing plate 47 from the top of the inclined bridge frame 2, and thus limiting the support plate 42.

[0034] Reference Figure 1 , Figure 4 and Figure 5The guide assembly 5 includes a support rod 51 fixedly installed in the middle of the horizontal cable tray 1. Winding wheels 52 are fixedly connected to the surfaces of both ends of the support rod 51. Slide grooves 53 are formed inside the front and rear sides of each winding wheel 52. A guide rod 541 is fixedly connected inside the slide groove 53. A buffer spring 542 is wound around the surface of the guide rod 541. A sliding block 55 is slidably connected to the top surface of the guide rod 541. The bottom end of the buffer spring 542 is fixedly connected to the bottom wall of the slide groove 53. The top end is fixedly connected to the bottom end of the sliding block 55. The right side of the sliding block 55 is rotatably connected to the limiting plate 561. Both the front and rear ends of the limiting plate 561 are fixedly connected to torsion springs 562. The bottom ends of the front and rear sides of the sliding block 55 are slidably connected to the inside of two slide grooves 53 respectively. The end of the torsion spring 562 away from the limiting plate 561 is fixedly connected to the surface of the sliding block 55. Under the action of the elastic force of the torsion spring 562, the limiting plate 561 is made to fit against the surface of the cable, thereby confining the cable inside the winding wheel 52.

[0035] Working principle: After the operator aligns the near ends of the horizontal cable tray 1 and the inclined cable tray 2, the front and rear connecting pieces 3 are connected at the connection point of the horizontal cable tray 1 and the inclined cable tray 2, thus initially defining the horizontal cable tray 1 and the inclined cable tray 2. Then, support plate 1 42 is placed against the bottom end of the inclined cable tray 2. Next, the threaded rod 1 45 is rotated, causing the sliding plate 441 to move closer to the inclined cable tray 2. At this time, the sliding plate 441 causes support plate 2 442 to move accordingly until the top of support plate 2 442 is against the bottom of the triangular rod 41, and the threaded holes of support plate 2 442 and triangular rod 41 are connected. Support plate 2 442 and triangular rod 41 can then be connected together using bolts and nuts. Afterwards... Then rotate the threaded rod 46 to push the pressing plate 47 to move towards the surface of the inclined cable tray 2 until the rubber pad fixed on the surface of the pressing plate 47 is in contact with the surface of the inclined cable tray 2. At this time, the lower pressing plate 482 will be in contact with the top wall of the inclined cable tray 2 under the elastic force of the pressure spring 483. At this time, the pressing plate 47 is limited by the mutual limitation of the rubber pad, the lower pressing plate 482 and the inclined cable tray 2, thereby limiting the mutual limitation of the support plate 42 and the inclined cable tray 2. Therefore, the position of the support plate 42 is fixed. Since the triangular rod 41 and the support plate 42 are mutually limited, the triangular rod 41 can pull the inclined cable tray 2 through the support plate 42, thereby preventing the inclined cable tray 2 from sinking.

[0036] The operator can then place the cable at the connection between the horizontal cable tray 1 and the inclined cable tray 2 into the top of the winding wheel 52, allowing the cable to pass between the winding wheel 52 and the sliding block 55. At this time, the sliding block 55 will be pulled downward under the force of the buffer spring 542. Then, the limiting plate 561 will rotate towards the winding wheel 52 under the force of the torsion spring 562. At this time, the limiting plate 561 will limit the cable inside the top of the winding wheel 52, thereby preventing the cable from bending at too small an angle at the connection between the horizontal cable tray 1 and the inclined cable tray 2, thus improving the safety of the cable during use.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
