Description
Technical Field
[0001] The present invention relates to the technical field of power supply and distribution, and in particular to an external handle which can be operated even when the cabinet is misplaced. Background Art
[0002] The handle is a carrier that facilitates the opening of the door. It has many forms and styles, but the design is mainly based on reliable operation and easy use. Some existing handles are used in power cabinets such as switch cabinets or distribution cabinets. The operation method of these handles is to connect the handle outside the cabinet to the handle connection port of the cabinet door, so that the handle outside the cabinet is connected to the operating shaft inside the cabinet, and the handle outside the cabinet is rotated to drive the movement of the internal operating shaft to complete a series of operations. However, the handle outside the cabinet has the following technical problems in the actual operation process: due to the deviation of the position of the handle connection port on the cabinet door, the handle cannot be normally connected to the internal operating shaft when it is connected to the handle connection port, and often the handle is forced to connect to the operating shaft for a series of operations. This not only makes the handle difficult to operate, but also causes the handle and the operating shaft to deform in the long run, and even affects the internal mechanism, reducing the service life of related linkage parts. Summary of the invention
[0003] In view of this, the purpose of the present invention is to provide an external cabinet handle that can be operated even if it is misaligned. Even if the position of the handle connecting port on the cabinet door and the operating axis inside the cabinet is deviated, it will not affect the normal operation of the handle, thereby greatly improving the service life of the cabinet body mechanism and handle.
[0004] In order to achieve the above objectives, the present invention adopts an external cabinet handle that can be operated even when misplaced, including a position adjustment component and a handle rotation component connected to the position adjustment component, the position adjustment component including a fixed plate, a first rotating disk arranged on one side of the fixed plate, and a second rotating disk arranged on the other side of the fixed plate, a first positioning axis and a first slide groove located on both sides of the first positioning axis are formed on the first rotating disk, a second positioning axis and a second slide groove located on both sides of the second positioning axis are formed on the second rotating disk, the first slide groove and the second slide groove are cross-arranged, a first positioning screw is respectively connected in the first slide groove, and a second positioning screw is respectively connected in the second slide groove, the first positioning screw and the second positioning screw are both connected to the fixed plate, and the handle rotation component is connected to the first positioning axis.
[0005] The operating principle of the above-mentioned external handle that can be operated even when misaligned is as follows: the second positioning shaft on the second rotating disk is connected to the switch center axis in the cabinet, and the first positioning shaft on the first rotating disk is connected to the handle rotating assembly (due to the cooperation of the first sliding groove on the first rotating disk and the first positioning screw, the first rotating disk can be kept moving relative to the fixed plate. Similarly, the cooperation of the second sliding groove on the second rotating disk and the second positioning screw allows the second rotating disk to be kept moving relative to the fixed plate, so that the handle rotating assembly and the switch center axis remain parallel). With such a position adjustment assembly structure, even if the switch center axis and the handle rotating assembly are not on the same axis, the two can be connected to each other. At this time, the operating handle rotating assembly rotates to rotate the first positioning shaft, driving the first rotating disk to rotate, and the fixed disk is driven to rotate under the action of the first positioning screw. The second rotating disk rotates with the fixed disk under the action of the second positioning screw, so that the second positioning shaft rotates at the same angle as the handle rotating assembly, thereby realizing the function of rotating even when misaligned. The external handle of the present invention can connect the misaligned switch center axis with the handle rotating assembly through the position adjustment assembly. Even if the switch center axis and the handle rotating assembly are misaligned, the switch center axis inside the cabinet will rotate at the same angle as the handle rotating assembly. The first slide groove and the second slide groove are cross-arranged to enable the position adjustment assembly to achieve connection in various misaligned directions. Such an external handle is reliable in operation and smooth in movement, thereby improving its own service life and the movement reliability of the mechanism inside the cabinet.
[0006] The present invention is further configured such that a first reset slot is formed on a side of the first rotating disk close to the fixed plate, and a second reset slot is formed on a side of the second rotating disk close to the fixed plate, and reset spring sheets are provided in the first reset slot and the second reset slot, one end of the first positioning screw passes through the fixed plate and is connected to the reset spring sheet in the second reset slot to form a linkage fit, and one end of the second positioning screw passes through the fixed plate and is connected to the reset spring sheet in the first reset slot to form a linkage fit.
[0007] The above-mentioned reset spring sheet is arranged to reset the first rotating disk and the second rotating disk to the initial position after the handle operation is completed, so as to facilitate the next operation. The first positioning screw is connected to the reset spring sheet in the second reset slot, and the second positioning screw is connected to the reset spring sheet in the first reset slot. The thickness of the position adjustment component can be reduced, and such a structure makes the matching stability of the position adjustment component better.
[0008] The present invention is further configured such that both ends of the reset spring piece form positioning ends, and the reset spring pieces are respectively connected to the opposite corners in the first reset slot and the opposite corners in the second reset slot through the two positioning ends. The middle part of the reset spring piece forms a recessed end, and the first positioning screw and the second positioning screw are respectively connected to the recessed ends of the reset spring piece.
[0009] The positioning end is used to stably connect the reset spring piece to the reset slot, and the recessed end is used to make the cooperation between the reset spring piece and the positioning screw more stable and reliable, thereby improving the accuracy of the reset position.
[0010] The present invention is further configured to form anti-dropping convex strips adapted to the side edges of the reset spring piece in both the first reset slot and the second reset slot.
[0011] The anti-dropping convex strip further improves the stability of the connection of the reset spring in the reset slot.
[0012] The present invention is further configured such that both the first positioning shaft and the second positioning shaft form square shaft holes.
[0013] The square shaft hole is used for connecting the first positioning shaft and the second positioning shaft to the short square shaft of the handle rotating assembly and the central shaft of the switch in the cabinet respectively.
[0014] The present invention is further configured such that the first slide grooves on both sides of the first positioning axis are centrally symmetrical, and the second slide grooves on both sides of the second positioning axis are centrally symmetrical, and the intersection angle between the first slide groove and the second slide groove is 90 degrees.
[0015] The above-mentioned setting of the angles of the first slide groove and the second slide groove is the optimal technical solution for the position adjustment component. Such a structure makes the operation of the handle most reliable and stable.
[0016] The present invention is further configured as a handle rotation assembly including a handle seat, a support member connected to one side of the handle seat, a handle connected to the other side of the handle seat, and a short square shaft inserted into the handle seat, wherein the support member forms a cavity inwardly on one side of the first positioning axis, and the inner wall of the cavity forms an inner slope surface inclined at a certain angle, and an outer slope surface adapted to the inclination angle of the inner broken surface is formed on the first positioning axis, and the first positioning axis is connected in the cavity and connected to the short square shaft.
[0017] The inner slope surface of the cavity and the outer slope surface on the first positioning shaft enable the handle rotating assembly to be smoothly connected to the position adjusting assembly, thus playing a guiding role.
[0018] The present invention is further configured to form an annular surface in the cavity, the annular surface is located on the inner side of the inner slope surface, a limiting boss is formed on the inner slope surface, a notch matched with the limiting boss is formed on the first positioning shaft, and the outer slope surface extends outward to form a skirt.
[0019] A limiting boss is provided on the inner slope surface of the above-mentioned cavity. After the handle is operated to close the switch, the boss limits the upper positioning shaft from being pulled out. The skirt on the outer slope surface of the first positioning shaft cooperates with the limiting boss to ensure that the distribution cabinet door cannot be opened when the switch is closed, thereby protecting personal safety. After the operating handle is rotated 90°, the notch on the first positioning shaft is used to disengage the limiting boss, so that the first positioning shaft can be pulled out normally to open the cabinet door after the switch is opened.
[0020] The present invention is further configured such that a positioning ring is formed on one side of the handle seat close to the handle, a positioning groove adapted to the positioning ring is formed on the handle, the handle is movably connected to the handle seat through the cooperation of the positioning groove and the positioning ring, and a plurality of padlock holes are formed on the positioning ring and the positioning groove.
[0021] The above structure enables the switch to be in the off state when the equipment is under maintenance, and the handle can be locked by three locks through the padlock hole to prevent misoperation. BRIEF DESCRIPTION OF THE DRAWINGS
