Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage withdrawable switch cabinet drawer units, in particular to a switch adapter for a low-voltage switch cabinet drawer. Background Art

[0002] The low-voltage withdrawable switchgear is composed of compartments such as busbar area (horizontal busbar and vertical busbar), cable area and functional unit area. The functional unit area is installed with several functional units, namely drawer units. A functional unit is composed of several electrical components connected into a functional unit and installed in a replaceable structural unit, which is called a drawer.

[0003] The drawer-type structural unit is generally a removable component composed of a universal circuit breaker, using a molded case circuit breaker, and specially designed removable components. In daily maintenance or fault repair, it involves the switch operation of the drawer. When installing the molded case switch, the existing drawer is only connected to the door panel operating handle through an 8mm*8mm square rod. As long as there is a slight error in the assembly of the door panel operating handle, it is difficult to form a concentric installation with the molded case switch, which will cause the molded case switch to be stuck when operated through the handle linkage. Once stuck, it is difficult to reset, which will cause the drawer to be stuck and unable to open. Utility Model Content

[0004] The main technical problem to be solved by the utility model is to provide a switch adapter for a low-voltage switch cabinet drawer, which is convenient for the molded case switch of the drawer unit to form a concentrically installed adapter with the door panel operating handle.

[0007] The two movable parts are connected to opposite sides of the fixed part. When one of the movable parts rotates, the fixed part is driven to link the other movable part to rotate, so that the two movable parts are concentrically arranged.

[0008] In a preferred embodiment, the movable members built into the two opposite slots slide in the slots to form an axial restriction, so that the movable members do not separate from the slots.

[0009] In a preferred embodiment, the movable part includes a U-shaped mounting seat, and key slots are coaxially provided on opposite sides of the U-shaped mounting seat. The housing switch or operating handle is inserted into the key slot with a connecting rod, and the connecting rod is locked in the U-shaped mounting slot with a screw.

[0010] In a preferred embodiment, the U-shaped mounting seat is provided with ears extending along both sides on one side, and the moving member is provided on the ears;

[0011] The ear forms an axial limit on the moving member so that the moving member does not separate from the slot.

[0012] In a preferred embodiment, the movable member is a positioning pin, and the positioning pin includes a roller for sliding connection with the slot.

[0013] In a preferred embodiment, the connecting rod is configured as a square rod with a rectangular cross section, and the keyway is configured as a square groove; the square groove is adapted to the square rod.

[0014] In a preferred embodiment, a screw locking hole is provided at the bottom of the U-shaped mounting seat, and the screw locks the connecting rod in the U-shaped mounting seat along a direction perpendicular to the length of the connecting rod.

[0028] refer to Figure 1-Figure 6This embodiment provides a switch adapter for a low-voltage switch cabinet drawer, through which the molded case switch and the operating handle 4 can form a good linkage, so that the shell switch 3 is flexible in operation and has more stable performance. The adapter includes a fixed part 1 and two movable parts 2.

[0029] The two movable parts 2 have the same structure, both including a U-shaped mounting groove, and the molded case switch and the operating handle 4 both include a connecting square rod 5, and key grooves 23 are arranged oppositely on the two side walls of the opening of the U-shaped mounting groove, and the key grooves 23 are arranged coaxially, and screw 6 locking holes are arranged at the bottom of the opposite opening of the U-shaped mounting groove. The connecting square rod 5 and the U-shaped mounting groove are assembled such that when the connecting square rod 5 is inserted into the two key grooves 23 of the U-shaped mounting groove, a screw 6 is used to lock the connecting square rod 5 in the U-shaped groove in a direction perpendicular to the length of the connecting square rod 5.

[0030] Specifically, the key slot 23 is adapted to the connecting square rod 5 to be set as a square slot, and the square slot forms a plug-in connection. On the one hand, it can well enable the connecting square rod 5 to form a linkage with the movable part 2. On the other hand, the square installation can facilitate the alignment of the corresponding screw 6 hole on the connecting square rod 5 with the screw 6 locking hole, so as to facilitate the locking installation of the screw 6.

[0031] In this embodiment, a fixing member 1 is provided, including a cross-shaped slot 11 arranged on the main body of the fixing member 1. The four slots 11 are arranged in a cross shape and are arranged opposite to each other in pairs. A movable member 2 forms a movable connection with two slots 11 axially oppositely arranged on the fixing member 1.

[0032] Specifically, an ear 24 is provided on the U-shaped mounting seat 22 of the movable part 2 at a side away from the operating handle 4 or the molded case switch. The ear 24 extends from the side to both sides. A movable part is fixed on the ear 24 and is slidably connected to the slot 11 .

[0033] In this embodiment, the movable member is configured as a positioning pin 21, and the positioning pin 21 includes a roller, and the roller forms a sliding connection with the slot 11. The setting of the roller can make the positioning pin 21 slide better in the slot 11, so that the linkage between the movable member 2 and the fixed member 1 is smoother. The positioning pins 21 provided on the corresponding two ears 24 are respectively installed in the two opposite slots 11 on the fixed member 1, and the positioning pins 21 built in the two opposite slots 11 slide in the slots to form an axial restriction, so that the movable member does not separate from the slot 11.

[0034] The ears 24 on both sides of one side of the U-shaped mounting seat 22 are fixed positions, the interval between the two ears 24 is fixed, the position of the positioning pin 21 set on the ear 24 is fixed, and the interval between the two slots 11 is fixed. When the positioning pin 21 slides in the slot 11, the depth of the slot 11 matches the position distance setting of the ear 24 to form an axial restriction. Even if the positioning pin 21 on one side moves to the bottom of the slot 11, the positioning pin 21 on the other side will not be separated from the slot 11 by the opening of the slot 11.

[0035] When installing the operating handle 4 and the shell switch 3, the adapter is installed between the operating handle 4 and the shell switch 3. The operating handle 4 is connected to the slot 11 set in the vertical direction of the fixed part 1 through the movable part 2; the shell switch 3 is connected to the slot 11 set in the horizontal direction of the fixed part through the movable part 2. The two movable parts 2 are connected to the opposite sides of the fixed part 1, and the sliding between the slot 11 and the positioning pin 21 is used to rotate and calibrate the concentric deviation of the linkage between the operating handle 4 and the shell switch 3 during use. When the operating handle 4 is rotated, the movable part 2 connected thereto is driven to rotate. The movable part 2 provides the circumferential rotational force of the fixed part 1 with the sliding of the positioning pin 21 in the slot 11. Under the circumferential rotation of the fixed part 1, the movable part 2 connected to the shell switch 3 is rotated, and then the sliding of the positioning pin 21 in the slot 11 is used for calibration, so that the two movable parts 2 are concentrically arranged, giving the shell switch 3 a certain space for operation, thereby avoiding the occurrence of jamming. When there is an installation error between the operating handle 4 and the shell switch 3, the adapter can calibrate the concentric rotation, making the mechanism more flexible and the performance more stable.

[0036] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
