DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0019] like Figure 1-Figure 9 As shown, a foldable and adjustable cable bracket proposed in one embodiment of the present application includes: A support plate 1, one side of the support plate 1 is open, a plurality of U-shaped movable frame plates 2 are vertically slidably mounted on the support plate 1, the movable frame plates 2 are horizontally arranged, a movable plate frame 3 is mounted between two free ends of the movable frame plates 2, a supporting rod 4 is vertically rotatably mounted on the movable plate frame 3, and the supporting rod 4 is used to hold and place cables; The actuator 5 is mounted on the support plate 1 and acts on the plurality of support rods 4. The actuator 5 drives the plurality of support rods 4 to rotate vertically. Figure 1 and Figure 2 As shown, the support rods 4 are in a folded state during handling and transportation, which is convenient for moving in a narrow area. After the support plate 1 is installed, the actuator 5 can drive multiple support rods 4 to rotate vertically at the same time until the support rods 4 and the support plate 1 remain vertical. At this time, the support rods 4 are in a horizontal state: The limiting mechanism 6 is installed on the movable plate frame 3 and acts on the movable frame plate 2. The limiting mechanism 6 is used to release the limiting or limit the movable frame plate 2 to slide. When the position of the support rod 4 needs to be adjusted, the limiting mechanism 6 is used to release the limiting of the movable frame plate 2, and then the movable frame plate 2 is moved. When the movable frame plate 2 moves, it will indirectly drive the support rod 4 to move. Then, the movable frame plate 2 can be limited by the limiting mechanism 6, thereby indirectly changing the position of the support rod 4, and the adjustment is more accurate, so that the cables can be arranged and laid to an ideal effect as needed; The positioning mechanism 7 is installed on the movable frame 2 and acts on the support rod 4. When the support rod 4 is rotated to the horizontal through the actuator 5, the positioning mechanism 7 is used to keep the support rod 4 horizontal. That is to say, after the plurality of support rods 4 are rotated to the horizontal through the actuator 5, when the actuator 5 no longer drives the support rod 4 to rotate, the positioning mechanism 7 is used to prevent the support rod 4 from rotating downward and folding again due to gravity or external force.

[0020] like Figure 1 and Figure 5 As shown, in some embodiments, the actuator 5 includes a sliding plate 501 horizontally slidably installed in the support plate 1, a driving rack 502 is vertically slidably installed on the sliding plate 501, an adjusting screw 503 is vertically and rotatably installed on the sliding plate 501, the driving rack 502 is threadedly sleeved on the adjusting screw 503, an adjusting component 504 for driving the sliding plate 501 to move is installed on the support plate 1, and a fixed gear 505 is constructed on the support rod 4, which is used to mesh with the driving rack 502. That is to say, when it is necessary to rotate multiple support rods 4, the adjusting screw 503 is rotated at this time, and the driving rack 502 will be driven to move vertically when the adjusting screw 503 rotates. Because the driving rack 502 is connected to the fixed The gear 505 is meshed, so when the driving rack 502 moves, it will drive the fixed gear 505 to rotate. When the fixed gear 505 rotates, it will indirectly drive the support rod 4 to rotate vertically, thereby realizing the rotation of multiple support rods 4 to the horizontal. When it is necessary to slide the support rod 4, the adjustment component 504 can be used to drive the sliding plate 501 to move away from the support rod 4, so that the driving rack 502 is away from the fixed gear 505, thereby releasing the limit on the rotation angle of the support rod 4, so that the moving frame plate 2 can be slid. After the moving frame plate 2 is moved, the driving rack 502 is moved to engage with the fixed gear 505 to limit the rotation angle of the support rod 4 again.

[0021] like Figure 5 - Figure 8As shown, in some embodiments, a guide rod 5041 is vertically installed in the support plate 1, and the adjustment component 504 includes a strip slide 5042 vertically slidably sleeved on the guide rod 5041, and a connecting plate 5043 is horizontally configured at the top of the strip slide 5042. A threaded rod 5044 is vertically rotatably installed on the support plate 1, and the connecting plate 5043 is threadedly sleeved on the threaded rod 5044. The top of the threaded rod 5044 is located outside the support plate 1 and is configured with a knob 5045. The design of the knob 5045 facilitates the rotation of the threaded rod 5044. A hinged rod 5046 is hinged between the strip slide 5042 and the sliding plate 501. When the knob 5045 is rotated, the rotation of the knob 5045 will drive the threaded rod 5044 to rotate. Because the connecting plate 5043 is threadedly matched with the threaded rod 5044, the threaded rod 5044 will drive the connecting plate 5043 to move vertically when it rotates, and the connecting plate 5043 will indirectly drive the strip slide 5042 to move when it moves, and the strip slide 5042 will drive the hinged rod 5046 hinged thereon to move when it moves. Because one end of the hinged rod 5046 is hinged on the sliding plate 501, when the strip slide 5042 moves, the sliding plate 501 will be driven horizontally through the hinged rod 5046, thereby realizing the horizontal movement of the driving rack 502. The threaded matching of the connecting plate 5043 and the threaded rod 5044 has good self-locking properties, which prevents the driving rack 502 from moving accidentally after it is moved.

[0022] like Figure 5 - Figure 8As shown, in some embodiments, two connecting rods 601 coaxial with the fixed gear 505 are symmetrically constructed on the support rod 4, the movable plate frame 3 is horizontally slidably installed on the movable frame plate 2, and the connecting rod 601 is rotatably installed on the movable plate frame 3. The limiting mechanism 6 includes two convex plates 602 symmetrically constructed on the movable plate frame 3, and the convex plates 602 are constructed with a limiting rack 603. Bar-shaped tooth grooves 604 are provided on the opposite side surfaces of the support plate 1 along its length direction, and the two limiting racks 603 are respectively located in the bar-shaped tooth grooves 604. The limiting racks 603 are used to engage with the tooth grooves of the bar-shaped tooth grooves 604. A resistance spring 605 is installed between the movable plate frame 3 and the movable frame plate 2. Specifically, a guide rod is horizontally constructed on the movable plate frame 3, and the guide rod is inserted in the movable frame plate 2. The resistance spring 605 is located at the movable frame plate 2 The internal interference spring 605 is prevented from being damaged by external collision. Under normal circumstances, the limit rack 603 is in meshing state with the tooth grooves of the bar tooth groove 604. At this time, the limit rack 603 and the fixed gear 505 can limit the movable frame plate 2. When the support rod 4 needs to be moved, it is only necessary to slide the movable frame plate 2 horizontally. The movable frame plate 2 indirectly drives the support rod 4 to move horizontally during the movement. When the support rod 4 moves horizontally, the fixed gear 505 will be disengaged from the driving rack 502. At the same time, the limit rack 603 is also disengaged from the tooth grooves of the bar tooth groove 604, so that only the support rod 4 that needs to be moved can be moved. At this time, due to the design of the positioning mechanism 7, the angle of the support rod 4 that needs to be moved will not rotate, so that the support rod 4 always remains in a horizontal state when it moves, which is more convenient to move.

[0023] like Figure 6 As shown, in some embodiments, a connecting block 702 is configured below the movable frame plate 2, and the positioning mechanism 7 includes a driving rod 703 that slides horizontally and penetrates the connecting block 702. A limiting block 701 is configured at one end of the driving rod 703 toward the supporting rod 4. The end of the limiting block 701 that faces the supporting rod 4 is triangular, and two inclined surfaces of the limiting block 701 are used to contact the supporting rod 4. An elastic component 8 is installed between the limiting block 701 and the movable frame plate 2. That is to say, when the supporting rod 4 in the folded state is rotated to the horizontal state, it will contact one of the inclined surfaces of the limiting block 701, so that the limiting block 701 moves The support rod 4 is moved until it rotates to the horizontal position, at which time the support rod 4 is no longer in contact with the limit block 701, so that the limit block 701 is reset to the bottom of the support rod 4 through the elastic component 8 to limit the support rod 4. When it is necessary to fold multiple support rods 4 again, it is only necessary to rotate the adjusting screw 503. At this time, the support rod 4 will conflict with the other inclined surface of the limit block 701, so that the limit block 701 moves again. The design of the two inclined surfaces of the limit block 701 ensures that the limit block 701 will not affect the simultaneous folding of multiple support rods 4, and it is convenient to fold the support rod 4 when the cable laying path needs to be temporarily changed.

[0024] like Figure 6 As shown, in some embodiments, the elastic component 8 includes a mounting cylinder 801 installed under the movable frame plate 2, a mounting rod 802 is slidably inserted at one end of the mounting cylinder 801, a connecting rod 803 is hinged between the mounting rod 802 and the limit block 701, and a return spring 804 is installed between the mounting cylinder 801 and the mounting rod 802. The mounting cylinder 801 is located below the movable frame plate 2 to ensure the overall flatness of the movable frame plate 2, and multiple support plates 1 are more stable when stacked and are easier to hold during transportation.

[0025] like Figure 6 As shown, in some embodiments, the cross-section of the support rod 4 is U-shaped and an extension plate 9 is installed horizontally and slidably inside. The free end of the extension plate 9 is constructed with a limiting plate 10 perpendicular to the extension plate 9. A locking piece 11 for limiting the sliding of the extension plate 9 is installed on the support rod 4. The design of the extension plate 9 can make the support rod 4 occupy a smaller space after being folded, so that more support rods 4 can be arranged on the support plate 1. When the support rod 4 is rotated to horizontal, the length of the support rod 4 is shorter at this time, and then the extension plate 9 can be moved so that the extension plate 9 slides out of the support rod 4 to indirectly increase the length of the support rod 4, and then the extension plate 9 is limited by the locking piece 11.

[0026] like Figure 6 As shown, in some embodiments, sliding grooves 1101 are provided on opposite sides of the support rod 4 along its length direction, and two sliding blocks 1102 are symmetrically constructed on the extension plate 9. The two sliding blocks 1102 are respectively slidably installed in the two sliding grooves 1101, and the locking member 11 includes two magnetic plates 1103 installed in the sliding grooves 1101. The two magnetic plates 1103 are respectively located on the two end surfaces of the sliding grooves 1101 that are away from each other, and the magnetic plates 1103 are used to adsorb the sliding blocks 1102. That is, when the extension plate 9 moves, the sliding block 1102 will move in the sliding groove 1101. When the extension plate 9 moves to the maximum limit position, the sliding block 1102 will contact one of the magnetic plates 1103, thereby adsorbing the sliding block 1102 together through the magnetic plate 1103. Preferably, the sliding block 1102 can be made of iron material that can be adsorbed by a magnet, and the magnetic plate 1103 can be a magnet.

[0027] like Figure 5As shown, in some embodiments, an adjusting ring 12 is rotatably installed on the inner top surface of the support plate 1, an inner gear ring 13 is installed inside the adjusting ring 12, the top end of the adjusting screw 503 is located outside the sliding plate 501 and is constructed with a driving gear 14 that meshes with the adjusting ring 12, and a portion of the adjusting ring 12 is exposed outside the opening of the support plate 1, so when it is necessary to rotate the adjusting screw 503, only the adjusting ring 12 needs to be rotated, and the inner gear ring 13 inside the adjusting ring 12 is meshed with the driving gear 14, so the rotation of the adjusting ring 12 will drive the adjusting screw 503 to rotate, thereby facilitating the rotation of the adjusting screw 503 and making it more convenient to use.

[0028] like Figure 1 and Figure 6 As shown, in some embodiments, the movable frame plate 2 is provided with a contact surface 15. When the support rod 4 is perpendicular to the support plate 1, one side of the support rod 4 in the length direction contacts the contact surface 15. When multiple support rods 4 are rotated to horizontal, they will contact the contact surface 15, thereby preventing the multiple support rods 4 from rotating at too large an angle, causing the support rods 4 to tilt and affecting the subsequent laying of cables.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
