[0003] Currently, the cable tray installation brackets lack adaptability. When facing cable trays of different widths, they cannot adjust their sizes accordingly. If the installation brackets are longer than the width of the cable trays, it will lead to uneven force and reduce stability. If they are shorter than the cable trays, the cable trays cannot be installed. At the same time, the cable tray installation brackets need to be able to be disassembled to improve transportability. Content of the Utility Model

The installation bracket component group includes a middle frame component box. A control button is arranged on the side surface of the middle frame component box. A bidirectional screw rod component is arranged inside the middle frame component box. A moving plate is arranged outside the bidirectional screw rod component. A cross plate component is in contact with the side surface of the moving plate. Through holes are opened on the cross plate component. Threaded hanging rods are in contact with the through holes. Hanging rod nuts are connected to the threaded hanging rods through threads. Bolt components and nut components are arranged on the cross plate component.

[0007] Preferably: The top surface of the middle frame component box is in contact with the bottom of the cable tray component. Both ends of the bidirectional screw rod component are connected to the middle frame component box through rotating shafts. One end of the rotating shaft of the bidirectional screw rod component is connected to the control button. Anti-slip patterns are arranged on the surface of the control button.

[0008] Preferably: There are two moving plates, and the two moving plates are symmetrically distributed on the bidirectional screw rod component.

[0012] Preferably, one end of the limit threaded rod contacts the surface of the bidirectional lead screw through an anti-slip gasket.

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

[0014] 1. The cable tray connection and installation bracket is provided with an installation bracket component group. Currently, the cable tray installation bracket lacks adaptability. When facing cable trays of different widths, it is impossible to adjust the size to adapt. If the installation bracket is longer than the width of the cable tray, it will cause uneven stress and reduce stability. If it is shorter than the cable tray, the cable tray cannot be installed. In the corresponding designed installation bracket component group, when adjusting and adapting to cable trays of different widths, by increasing or decreasing the number of cross plates, the overall size of the bracket can be increased or decreased significantly. The multiple cross plates are connected and fixed by bolts and nuts. After adjusting to approximately the appropriate size for the corresponding cable tray component, by rotating the control button, the rotation of the control button will drive the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw drives the two moving plates to move through the nut pair, and the two moving plates will only move in opposite directions, thereby slightly increasing or decreasing the overall length of the bracket. By adjusting the bracket length significantly and slightly, it can adapt to cable trays of different widths. After adaptation, the size of the installation bracket corresponds to that of the cable tray component, and it can support the cable tray component more stably and reliably;

[0015] 2. The cable tray connection and installation bracket is provided with an installation bracket component group. During the transportation of the installation bracket component group, after disassembling between the multiple cross plates and then disassembling the connection between the cross plates and the moving plates, the cross plates can be separated from the middle frame part box. Thus, the middle frame part box and the cross plates can be carried and stored separately, which can make more effective use of the storage space and thus reduce the transportation cost.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A cable tray connection installation bracket includes a cable tray part 01. An installation bracket component group 02 is arranged outside the cable tray part 01. The installation bracket component group 02 includes a middle frame part box 21. A control button 22 is arranged on the side surface of the middle frame part box 21. A bidirectional lead screw part 23 is arranged inside the middle frame part box 21. A moving plate 24 is arranged outside the bidirectional lead screw part 23. A cross plate part 25 is in contact with the side surface of the moving plate 24. A through hole 26 is opened on the cross plate part 25. A threaded suspension rod 27 is in contact with the through hole 26. A suspension rod nut 28 is connected to the threaded suspension rod 27 by threads. A bolt part 29 and a nut part 210 are arranged on the cross plate part 25. A limit threaded rod 211 is arranged on the side surface of the bidirectional lead screw part 23.

[0024] The top surface of the middle frame part box 21 is in contact with the bottom of the cable tray part 01. Both ends of the bidirectional lead screw part 23 are connected to the middle frame part box 21 through rotating shafts. One end of the rotating shaft of the bidirectional lead screw part 23 is connected to the control button 22. The surface of the control button 22 is provided with anti-slip patterns.

[0025] There are two moving plates 24, and the two moving plates 24 are symmetrically distributed on the bidirectional screw rod member 23. The moving plate 24 is connected to the bidirectional screw rod member 23 through a nut pair, and the moving plate 24 is in sliding contact with the middle frame member box 21 through a chute.

[0026] There are two cross plate members 25, and the two cross plate members 25 are connected by a bolt member 29 and a nut member 210. The moving plate 24 and the cross plate member 25 are connected by a bolt member 29 and a nut member 210.

[0027] One end of the threaded suspension rod 27 is connected to the wall surface. The threaded suspension rod 27 passes through the through hole 26, and the side surface of the suspension rod nut 28 contacts the bottom of the cross plate member 25.

[0028] The limit threaded rod 211 is connected to the middle frame member box 21 by threads.

[0029] One end of the limit threaded rod 211 contacts the surface of the bidirectional screw rod member 23 through an anti-slip gasket. The number of cross plate members 25 in the mounting bracket component group 02 can be increased or decreased according to the usage requirements, so as to greatly increase or decrease the length of the overall bracket.

[0030] Working principle: At present, the cable tray installation bracket lacks adaptability. When facing cable trays of different widths, it is impossible to adjust the size for adaptation. If the installation bracket is longer than the width of the cable tray, it will cause uneven stress and reduce stability. If it is shorter than the cable tray, the cable tray cannot be installed. In the corresponding designed installation bracket component group 02, when adjusting and adapting to cable trays 01 of different widths, by increasing or decreasing the number of cross plate members 25, the overall size of the bracket can be greatly increased or decreased. The multiple cross plate members 25 are connected and fixed by bolt members 29 and nut members 210. After adjusting to approximately the appropriate size for the corresponding cable tray 01, by controlling the rotation of the control button 22, the rotation of the control button 22 drives the bidirectional screw rod member 23 to rotate. The rotation of the bidirectional screw rod member 23 drives the two moving plates 24 to move through the nut pair, and the two moving plates 24 will only move in opposite directions, thereby slightly increasing or decreasing the length of the overall bracket. Through the large-scale and small-scale adjustment of the bracket length, the cable trays 01 of different widths can be adapted. After adaptation, the size of the installation bracket corresponds to that of the cable tray 01, and the cable tray 01 can be supported more stably and reliably. During the transportation of the installation bracket component group 02, after disassembling between the multiple cross plate members 25 and then disassembling the connection between the cross plate members 25 and the moving plates 24, the cross plate members 25 can be separated from the middle frame member box 21. Thus, the middle frame member box 21 and the cross plate members 25 can be carried and stored separately, which can more effectively utilize the storage space and thus reduce the transportation cost.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
