DETAILED DESCRIPTION

[0033] like Figure 1-7 As shown, the present invention provides a sunshade for an inverter, comprising a mounting frame 1, a top plate 4 fixed on the top of the mounting frame 1, a first connecting plate 2 and a second connecting plate 3 respectively fixed on the front and rear sides of the bottom of the mounting frame 1, and an adsorption rod 7 and a locking rod 5 respectively arranged on the first connecting plate 2 and the second connecting plate 3, the first connecting plate 2 and the second connecting plate 3 are both arranged along the width direction of the mounting frame 1, clamping bolts 8 threadedly connected to the adsorption rod 7 are equidistantly arranged at the bottom of the adsorption rod 7, a suction cup 9 is connected to the screw end of the clamping bolt 8, a winding shaft 13 is rotatably arranged in the mounting frame 1, a locking structure is connected to the winding shaft 13, a curtain 17 is wound on the winding shaft 13, and a curtain 17 connecting structure is provided at the bottom of the adsorption rod 7.

[0034] According to the size of the inverter, the mounting bracket 1 is placed above the inverter, and the locking rod 5 and the adsorption rod 7 are placed on the front and back sides of the inverter respectively. Then, the clamping bolt 8 on the adsorption rod 7 is rotated to push the suction cup 9 toward the inverter during the rotation, so that the suction cup 9 presses the inverter to ensure the clamping and adsorption of the inverter by the suction cup 9. Connecting rods are vertically fixed at the bottom of the four corners of the top plate 4. The connecting rods are used to connect the mounting bracket 1. While the top plate 4 provides shade for the inverter, there is a sufficient distance between the top plate 4 and the inverter to reduce heat transfer. The curtain 17 is unrolled by rotating the reel 13. The curtain 17 is located in front of the inverter LCD screen and is used to shade the LCD screen. The curtain 17 is retracted by rotating the reel 13 to observe the LCD screen.

[0035] like Figure 1 The bottom of the locking rod 5 is provided with a connection hole adapted to the inverter backplane mounting hole, and a locking bolt 6 adapted to the connection hole is arranged in the connection hole. The adsorption rod 7 and the locking rod 5 are respectively arranged to slide along the length direction of the first connecting plate 2 and the second connecting plate 3, and the adsorption rod 7 and the locking rod 5 are both provided with a position locking structure.

[0036] Since the connecting hole on the locking rod 5 is compatible with the mounting hole of the inverter back plate, when fixing the locking rod 5, it is necessary to slide the locking rod 5 so that the connecting hole on the locking rod 5 is aligned with the mounting hole, and then connect the locking rod 5 to the inverter back plate through the locking bolt 6, and fix the inverter back plate on the inverter.

[0037] The sliding arrangement of the adsorption rod 7 can prevent the suction cup 9 from squeezing and adsorbing the liquid crystal screen of the inverter when the adsorption rod 7 is adsorbed and connected to the front of the inverter.

[0038] like Figure 1 , Figure 2 and Figure 6 As shown. Both ends of the first connecting plate 2 and the second connecting plate 3 are horizontally provided with a strip-shaped width adjustment groove 15, the position locking structure is slidably arranged in the width adjustment groove 15, the inner top surface and the inner bottom surface of the width adjustment groove 15 are respectively provided with wedge-shaped surfaces adapted to the top surface and the bottom surface of the position locking structure, and one end of the position locking structure is provided with a pressure adjustment structure for pressing the top surface and the bottom surface of the position locking structure against the inner wall of the width adjustment groove 15.

[0039] The width adjustment slot 15 is provided so that the position locking structure can slide along the width adjustment slot 15, and then the locking rod 5 and the adsorption rod 7 can move along the second connecting rod 3 or the first connecting rod 2 respectively, so as to realize the sliding of the locking rod 5 and / or the adsorption rod 7 in position. Then, the position locking structure is pressed into the width adjustment slot 15 by the pressure adjustment structure to realize the locking of the position.

[0040] like Figure 6 The position locking structure includes a locking nut 22 slidably arranged in the width adjustment slot 15, the locking nut 22 is in the shape of a hexagonal pyramid, the pressure adjustment structure is a locking screw 16 threadedly connected to the locking nut 22, the locking screw 16 passes through the adsorption rod 7 or the locking rod 5, and the opening side of the width adjustment slot 15 close to the large end surface of the locking nut 22 is covered with a stop plate 23.

[0041] By rotating the locking screw 16, since the inner wall of the width adjustment slot 15 is adapted to the locking nut 22, the locking nut 22 cannot rotate during the rotation of the locking screw 16. Then, by rotating the locking screw 16, the locking nut 22 is further moved toward the inside of the width adjustment slot 15, and the side wall of the locking nut 22 is pressed against the inner wall of the width adjustment slot 15, thereby achieving position locking.

[0042] An expansion tube may also be provided and connected to the locking screw 16 . The locking screw 16 is rotated to expand the expansion tube, thereby squeezing the inner wall of the width adjustment slot 15 to achieve position locking.

[0043] like Figure 1 , Figure 2 , Figure 4 and Figure 5 The locking structure includes a ratchet 19 fixedly connected to the winding shaft 13 and a pawl 20 slidably connected to the mounting frame 1 and adapted to the ratchet 19, and a spring is connected to the end of the pawl 20 away from the ratchet 19. The locking structure is a limit structure of the winding shaft 13 in the unwinding direction.

[0044] In the process of adjusting the curtain 17, by rotating the ratchet 19 in the positive direction (clockwise), the pawl 20 will not hinder the rotation of the ratchet 19, so that the curtain 17 can be rolled up, which is convenient for the staff to observe the inverter LCD screen. By pushing the pawl 20 so that the pawl 20 is away from the ratchet 19, the ratchet 19 can be rotated in the reverse direction.

[0045] like Figure 5 As shown. One end of the reel shaft 13 is connected to an adjustment handle 14, and one end of the pawl 20 away from the ratchet 19 is fixedly connected to an L-shaped handle 21, and the handle 21 is slidably connected to the mounting frame 1. The handle 21 is used to conveniently separate the pawl 20 from the state of being connected to the ratchet 19, so that the ratchet 19 can rotate arbitrarily, which is convenient for lowering the curtain 17 to shade the inverter LCD screen.

[0046] like Figure 1 and Figure 4As shown. The connection structure includes a support plate 11 horizontally fixed to the bottom end of the adsorption rod 7, and the movable end of the curtain 17 is fixedly connected to a counterweight bar 18, and the top surface of the support plate 11 is provided with a locking structure of the counterweight bar 18. The movable end of the curtain 17 is fixed by the counterweight bar 18, and after the curtain 17 is lowered by the reel 13, the counterweight bar 18 is inserted into the support plate 11, and the movable end of the curtain 17 is connected by the support plate 11 to prevent the curtain 17 from shaking due to wind.

[0047] like Figure 1 and Figure 4 The locking structure includes a clamping groove 12 opened on the top surface of the support plate 11, the cross-section of the counterweight bar 18 is circular, the clamping groove 12 is an arc groove adapted to the counterweight bar 18, and an elastic clamping ball is arranged on the top of the clamping groove 12.

[0048] An opening is provided in the clamping groove 12, in which a spring is installed, and the movable end of the spring is connected to an elastic clamping ball. The movable end diameter of the opening is smaller than the outer diameter of the elastic clamping ball, so that the elastic clamping ball cannot be removed from the opening; by clamping the counterweight bar 18 into the clamping groove 12, the elastic clamping ball is located at the top of the counterweight bar 18, and the counterweight bar 18 is clamped.

[0049] like Figure 1-3 As shown. A guide bar 10 is fixedly provided on one side of the mounting frame 1. The guide bars 10 are arranged in pairs. The curtain 17 passes between the two guide bars 10. The guide bar 10 is located directly above the clamping groove 12. The cross section of the guide bar 10 is circular. The guide bar 10 is provided to support the curtain 17 in cooperation with the reeling shaft 13, and the lowering direction of the curtain 17 is set.

[0050] A method for using a sunshade for an inverter comprises the following steps: Step 1: Put the mounting frame 1 on the top of the inverter, place the locking rod 5 on the back panel side of the inverter, and place the adsorption rod 7 on the panel side of the inverter. According to the position of the threaded hole on the back panel of the inverter, move the locking rod 5 along the second connecting plate 3 so that the locking bolt 6 on the locking rod 5 is aligned with the screw hole on the back panel of the inverter, and move the adsorption rod 7 to both sides of the LCD screen of the inverter panel; Step 2: Remove the bolts on the inverter backplane, lock the locking rod 5 and the inverter backplane through the locking bolt 6 on the locking rod 5, and then press the suction cup 9 on the inverter panel by rotating the clamping bolt 8, and connect the suction rod 7 and the inverter through the suction cup 9; Step 3: Pull out the handle 21 to separate the pawl 20 from the ratchet 19, and compress the spring connected to the end face of the pawl 20, and rotate the reel-up shaft 13 by adjusting the handle 14 to unwind the curtain 17, so that the counterweight bar 18 at the movable end of the curtain 17 enters the clamping groove 12 on the support plate 11, and the counterweight bar 18 is locked by the clamping groove 12; Step 4: When the LCD screen of the inverter needs to be observed, the weight bar 18 is pulled out from the clamping groove 12, and the reeling shaft 13 is rotated in the forward direction to reel in the curtain 17, and then step 3 is performed to reset the curtain 17.
