[0034] The following further describes the present application in detail with reference to Figures 1-4 the accompanying drawings.

[0035] An embodiment of the present application discloses a drawer structure. Referring to Figure 1 , the drawer structure includes a drawer body 1, a disconnecting switch 2, a rotating handle 3 and a link mechanism. The disconnecting switch 2 is installed in the drawer body 1 and is used to control the on / off of the circuit. The rotating handle 3 is rotatably connected to the drawer body 1 and extends to the outside of the drawer body 1, facilitating operation by an operator from the outside. One end of the link mechanism is connected to the rotating handle 3, and the other end clamps the control handle of the disconnecting switch 2. When the rotating handle 3 rotates, through the transmission of the link mechanism, the control handle of the disconnecting switch 2 can be pushed to swing, thereby realizing the opening and closing control of the disconnecting switch 2. Among them, the rotation axis of the control handle of the disconnecting switch 2 relative to the disconnecting switch 2 is parallel to the rotation axis of the rotating handle 3 relative to the drawer body 1.

[0036] Referring to Figure 2 , the link mechanism includes a first connecting piece 4 and a second connecting piece 5. The first connecting piece 4 is strip-shaped. One end of the first connecting piece 4 is connected to the rotating handle 3, and the other end is hinged to the second connecting piece 5, enabling the second connecting piece 5 to swing relative to the first connecting piece 4.

[0037] Among them, the second connecting piece 5 includes a connecting part 53 and a clamping part 52. Both the connecting part 53 and the clamping part 52 are strip-shaped and are connected to each other, and the connecting part 53 is perpendicular to the clamping part 52. One end of the connecting part 53 away from the clamping part 52 is hinged through a pin shaft. The rotation axis between the connecting part 53 and the clamping part 52 is parallel to the rotation axis of the rotating handle 3. The length extension direction of the clamping part 52 is parallel to the rotation axis extension direction of the rotating handle 3. The clamping part 52 is used to clamp the control handle of the disconnecting switch 2 through the adjusting hole 7, so that power can be transmitted when the rotating handle 3 rotates, realizing the control of the disconnecting switch 2.

[0038] Referring to Figure 1 and Figure 2, To further enhance the stability and accuracy of control, a mounting seat 6 is provided inside the drawer body 1. The second connecting piece 5 further includes an extension part 51. The extension part 51 is strip-shaped, and one end of the extension part 51 is fixed to the end of the clamping part 52 away from the connecting part 53. The end of the extension part 51 away from the clamping part 52 is rotatably connected to the mounting seat 6 through a rotating part such as a bearing or a pin shaft. The rotation axis between the extension part 51 and the mounting seat 6 coincides with the rotation axis of the control handle of the circuit breaker switch 2, so as to improve the stability of the second connecting piece 5 driving the control handle to swing.

[0039] Refer to Figure 2 In addition, in order for the circuit breaker switch 2 to adapt to control handles of different lengths, an adjustment hole 7 extending along its own length direction is provided on the clamping part 52. The clamping part 52 clamps the control handle through the adjustment hole 7, and the extension length of the adjustment hole 7 is greater than the extension length of the control handle, so as to facilitate the cooperation between the control handle and the clamping part 52.

[0040] Refer to Figure 1 and Figure 3 , Further, the rotating handle 3 includes a rotating shaft 31 and an adjustment sleeve 32. A connecting seat 8 is fixed inside the drawer. The rotating shaft 31 is rotatably connected to the connecting seat 8, and the first connecting piece 4 is fixed to the rotating shaft 31. The adjustment sleeve 32 is coaxially sleeved on the outer wall of the rotating shaft 31 and can move axially relative to the rotating shaft 31. At the same time, the adjustment sleeve 32 also slidably penetrates through the panel of the drawer body 1, and one end of the adjustment sleeve 32 located outside the drawer body 1 has a handle, which is convenient for operating the adjustment sleeve 32 from the outside.

[0041] Refer to Figure 3 and Figure 4 , wherein, a guiding part 16 protruding from the outer wall of the rotating shaft 31 is provided on the outer wall of the rotating shaft 31. A guiding groove 17 for the guiding part 16 to slide is provided on the inner wall of the adjustment sleeve 32. The guiding groove 17 does not penetrate through the opposite ends of the adjustment sleeve 32, so that while the guiding part 16 guides the moving direction of the adjustment sleeve 32 relative to the rotating shaft 31, the moving distance of the adjustment sleeve 32 on the rotating shaft 31 is limited, preventing the adjustment sleeve 32 from detaching from the rotating shaft 31.

[0042] Refer to Figure 2 and Figure 3, a plug-in 11 moves radially along the rotating shaft 31 between the connecting seat 8 and the rotating shaft 31, and the plug-in 11 is block-shaped. The rotating shaft 31 has two slots 12 for the plug-in 11 to be inserted along its circumference. When the plug-in 11 is inserted into the slots 12, the rotation of the rotating shaft 31 can be restricted. The positions of the two slots 12 are respectively opposite to the opening and closing states of the circuit breaker 2. When the plug-in 11 is inserted into one of the slots 12, the control handle of the circuit breaker 2 is in the open state to turn on the circuit breaker 2. When the plug-in 11 is inserted into the other slot 12, the control handle of the circuit breaker 2 is pushed to the circuit breaker state to turn off the circuit breaker 2.

[0043] Among them, there is a first elastic member 14 between the plug-in 11 and the connecting seat 8 for pushing the plug-in 11 to be inserted into the slot 12. The first elastic member 14 includes a first spring 141, a guide rod 142 and a limit head 143. The guide rod 142 is slidably inserted into the connecting seat 8 along the direction of the plug-in rotating shaft 31, and the end of the guide rod 142 close to the plug-in 11 is fixed on the plug-in at the same time. The first spring 141 is sleeved on the outer wall of the guide rod 142, and the opposite ends of the first spring 141 are respectively connected to the side of the connecting seat 8 opposite to the plug-in 11, and the first spring 141 gives the plug-in 11 an elastic force to move toward the rotating shaft 31. The limit head 143 is fixed on the outer wall of the guide rod 142 and is opposite to the side of the connecting seat 8 away from the rotating shaft 31, so as to limit the depth of the plug-in 11 inserted into the rotating shaft 31.

[0044] Reference Figure 3 and Figure 4 In addition, the end of the plug 11 for plugging the rotating shaft 31 has an inclined surface 13 facing the adjustment sleeve 32, and the inclined surface 13 extends from the direction away from the adjustment sleeve 32 to the direction close to the rotating shaft 31. When the limit head 143 abuts against the connecting seat 8, the side of the inclined surface 13 close to the adjustment sleeve 32 is located outside the rotating shaft 31, so that when the adjustment sleeve 32 moves toward the inside of the drawer, it can abut against the inclined surface 13, so that the plug 11 is pushed away from the slot 12 by the guidance of the inclined surface 13, and the rotation restriction of the rotating shaft 31 is released. Then, the adjustment sleeve 32 is rotated to drive the rotating shaft 31 to rotate, so as to adjust the relative position of the plug 11 and the rotating shaft 31. The operation of pressing the adjustment sleeve 32 first and then rotating and adjusting the adjustment sleeve 32 can improve the safety of operation and reduce the possibility of misoperation.

[0045] Reference Figure 3At the same time, in order to facilitate the operator to sense the position of the adjustment sleeve 32 and control its moving distance, the outer wall of one end of the rotating shaft 31 rotating on the connecting seat 8 has a sliding portion 9, and the sliding portion 9 protrudes from the outer wall of the rotating shaft 31. The inner wall of the connecting seat 8 used to sleeve the rotating shaft 31 is provided with a sliding groove 10 for the sliding portion 9 to move circumferentially along the rotating shaft 31. The positions of the sliding grooves 10 away from the two ends are respectively opposite to the positions of the two slots 12, so that when the adjusting sleeve 32 rotates to drive the sliding portion 9 to abut against the two ends of the sliding groove 10 respectively, the connecting rod mechanism pushes the control handle of the circuit breaker 2 to the open circuit state and the circuit breaker state respectively.

[0046] Reference Figure 3 Furthermore, the inner cavity of the adjustment sleeve 32 has a second elastic member 15 connecting the adjustment sleeve 32 and the rotating shaft 31, and the second elastic member 15 includes a second spring 151 whose two ends are respectively connected to the inner wall of the adjustment sleeve 32 and the end wall of the rotating shaft 31. The elastic force of the second spring 151 is used to drive the adjustment sleeve 32 to move outside the drawer, so that after the operator releases the adjustment sleeve 32, the adjustment sleeve 32 can automatically return to the initial position. After the adjustment sleeve 32 returns to the initial position, the plug-in 11 is plugged into the current corresponding slot 12.

[0047] The implementation principle of a drawer structure in an embodiment of the present application is: first press the adjustment sleeve 32 to unlock the plug-in 11, and then rotate the adjustment sleeve 32 to drive the rotating shaft 31 to rotate, so as to link the first connecting piece 4 and the second connecting piece 5 to move, so that the second connecting piece 5 pushes the control handle of the circuit breaker 2 to change its position.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
