[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1 , Figure 2As shown, this utility model provides a retractable electrical equipment mounting bracket, including a mounting bracket mechanism 1. An electrical equipment cabinet 2 is mounted on the top of the mounting bracket mechanism 1. The mounting bracket mechanism 1 includes a U-shaped placement plate 11. A limiting plate is fixedly mounted on the rear top side of the U-shaped placement plate 11. An adjusting box 12 is fixedly mounted in the middle of the front side of the U-shaped placement plate 11. An adjusting threaded rod 13 is movably mounted on the rear inner wall of the adjusting box 12. The rear end of the adjusting threaded rod 13 extends through to the rear side of the U-shaped placement plate 11 and is fixedly mounted with an adjusting knob 14. The outer wall of the adjusting threaded rod 13 is threaded with... There is a telescopic box 15, which is slidably connected to the inner cavity of the adjustment box 12. An L-shaped clamping plate 16 is fixedly installed at the front end of the telescopic box 15. The top of the horizontal part of the L-shaped clamping plate 16 is on the same horizontal line as the top of the U-shaped placement plate 11. Telescopic plates 17 are fixedly installed on the left and right sides of the rear end of the L-shaped clamping plate 16. Sliding compartments are opened on the left and right sides of the front end of the U-shaped placement plate 11. The two telescopic plates 17 are slidably connected to the two sliding compartments respectively. A left and right telescopic mechanism 18 is provided at the bottom of the U-shaped placement plate 11. A quick release mechanism 19 is provided at the rear side of the U-shaped placement plate 11.
[0023] During initial installation, the electrical equipment cabinet 2 is placed on top of the U-shaped placement plate 11. Rotating the adjustment knob 14 will rotate the adjustment threaded rod 13 inside the adjustment box 12. The threaded connection between the telescopic box 15 and the adjustment threaded rod 13 will drive the telescopic box 15 to move the L-shaped clamping plate 16 backward. At the same time, the two telescopic plates 17 will also move backward in the sliding compartment to maintain stability until the vertical part of the L-shaped clamping plate 16 abuts against the bottom front side of the electrical equipment cabinet 2. At this time, the rear side of the electrical equipment cabinet 2 will also abut against the limiting plate on the rear top side of the U-shaped placement plate 11, thus completing the front and rear position fixation.
[0024] like Figure 3 , Figure 4As shown, the left and right telescopic mechanism 18 includes a control box 181, which is fixedly installed at the bottom of the U-shaped placement plate 11. Threaded rods 182 are movably installed on both the left and right sides of the inner wall of the control box 181. Moving plates 183 are threadedly installed on the outer walls of both threaded rods 182. The four sides of the two moving plates 183 overlap with the four sides of the inner wall of the control box 181. Tension plates 184 are fixedly installed on the front and back sides of the opposite sides of the two moving plates 183, and the ends of the two tension plates 184 on each side, away from the moving plates 183, respectively penetrate into the control box 181. L-shaped clamping plates 185 are fixedly installed on the left and right sides of the control box 181. The horizontal position of the two L-shaped clamping plates 185 is higher than the top of the U-shaped placement plate 11. Bevel gears 1821 are fixedly installed on the opposite ends of the two threaded rods 182. A rotating rod 1811 is movably installed at the top center of the control box 181. The bottom end of the rotating rod 1811 extends through to the bottom of the control box 181 and is fixedly installed with a synchronous drive knob 1813. A bevel gear 1812 is fixedly installed on the outer wall of the rotating rod 1811. The bevel gear 1812 meshes with the two bevel gears 1821.
[0025] The rotation of the rotating rod 1811 and the bevel gear 1812 can be controlled by rotating the synchronous drive knob 1813 at the bottom of the control box 181. The meshing of the bevel gear 1812 with the two bevel gears 1821 drives the two threaded rods 182 on the left and right sides of the inner cavity of the control box 181 to rotate. This simultaneously drives the movable plates 183 threaded on the outer wall of the two threaded rods 182 to move closer to each other. The tension plate 184 pulls the two L-shaped clamping plates 185 to move closer to each other, thus completing the clamping and fixing of the left and right sides of the electrical equipment cabinet 2.
[0026] like Figure 5 As shown, the quick-release mechanism 19 includes a fixed rear plate 191 and a wall mounting plate 192. The wall mounting plate 192 is located behind the fixed rear plate 191. The fixed rear plate 191 is fixedly installed behind the U-shaped placement plate 11. An extension plate 195 is fixedly installed on the upper front side of the fixed rear plate 191. The fixed rear plate 191 has a through slot. An insert plate 196 is fixedly installed on the front side of the wall mounting plate 192. The insert plate 196 passes through the slot to the bottom of the extension plate 195. Both the extension plate 195 and the insert plate 196 are... The wall mounting plate 192 has two through-holes 197. The inner threads of the two through-holes 197 are fitted with locking thread rods 198. The top of the locking thread rods 198 is fixedly fitted with locking knobs 199. The front left and right sides of the wall mounting plate 192 have two through-holes 194. The rear left and right sides of the back plate 191 are fixedly bonded with rubber pads 193. The thickness of the rubber pads 193 is the same as the thickness of the wall mounting plate 192. After installation, the rubber pads 193 can resist the wall and provide a certain support force.
[0027] During initial installation, the wall mounting plate 192 can be fixed to the wall at a specified height using bolts through the bolt holes 194. Then, the slot on the fixing plate 191 on the back of the U-shaped placement plate 11 is aligned with the insert plate 196 and inserted, so that the insert plate 196 passes through the slot and is aligned vertically with the extension plate 195. At this time, the threaded holes 197 on the insert plate 196 and the extension plate 195 are also in a vertically connected state. Then, simply rotate the locking knob 199 to pass the locking thread rod 198 through the two threaded holes 197 to complete the fixation. The U-shaped placement plate 11 can then be installed. When disassembling next time, simply reverse the locking knob 199 to remove the locking thread rod 198 and pull the U-shaped placement plate 11 together with the fixing plate 191 forward to complete the disassembly, thus improving the efficiency of disassembly and assembly.
[0028] The working principle of this retractable electrical equipment mounting bracket will be explained in detail below.
[0029] like Figure 1-5 As shown, during initial installation, the electrical equipment cabinet 2 is placed on top of the U-shaped placement plate 11. Rotating the adjustment knob 14 rotates the adjustment threaded rod 13 inside the adjustment box 12. The threaded connection between the telescopic box 15 and the adjustment threaded rod 13 drives the telescopic box 15 to move the L-shaped clamping plate 16 backward. Simultaneously, the two telescopic plates 17 move backward within the sliding compartment to maintain stability until the vertical portion of the L-shaped clamping plate 16 abuts against the bottom front of the electrical equipment cabinet 2. At this point, the rear of the electrical equipment cabinet 2 also abuts against the limiting plate at the rear top of the U-shaped placement plate 11, thus fixing the front and rear positions. Simultaneously, rotating the synchronous drive knob 1813 at the bottom of the control box 181 controls the rotation of the rotating rod 1811 and the bevel gear 1812. The meshing of the bevel gear 1812 with the two bevel gears 1821 drives the two threaded rods 182 on the left and right sides of the inner cavity of the control box 181 to rotate, thereby simultaneously driving the two threaded rods 1811. 2. The movable plates 183 installed on the outer wall threads move closer together. The tension plate 184 pulls the two L-shaped clamping plates 185 closer together, finally completing the clamping and fixing of the left and right sides of the electrical equipment cabinet 2. During the initial installation, the wall mounting plate 192 can be fixed to the wall at a specified height by bolts through the bolt holes 194. Then, the slot opened on the fixed back plate 191 on the back side of the U-shaped placement plate 11 is aligned with the insertion plate 196 and inserted, so that the insertion plate 196 passes through the slot and is aligned vertically with the extension plate 195. At this time, the threaded holes 197 opened on the insertion plate 196 and the extension plate 195 are also in a vertically connected state. Then, the locking thread rod 198 can be fixed by rotating the locking knob 199 through the two threaded holes 197. The U-shaped placement plate 11 can be installed. When disassembling next time, simply reverse the locking knob 199 to remove the locking thread rod 198 and directly pull the U-shaped placement plate 11 together with the fixed back plate 191 forward to complete the disassembly.
[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
