Description

Technical Field

[0001] The present invention relates to the technical field of low-voltage electrical appliances, and in particular to an operating mechanism of a switch device used in a narrow space. Background Art

[0002] The word "switch" means "on" and "off." It also refers to an electronic component that can open a circuit, interrupt current flow, or redirect it to another circuit. The most common switch is a human-operated electromechanical device with one or more electronic contacts. A "closed" contact conducts electricity, allowing current to flow; an "open" switch means the contacts are disconnected, preventing current from flowing.

[0003] The existing mechanism technology cannot be directly transplanted to a small space for use. The mechanism needs to occupy a large space in the switch device due to rotation. In addition, the existing mechanism has only two states, namely the open and closed states. For some special distribution cabinets, the mechanism needs to reach a certain state before the product can be pulled out of the cabinet. Therefore, the two states of the existing mechanism technology cannot meet the requirements. Therefore, we propose a switch device operating mechanism for use in narrow spaces to effectively solve the above disadvantages. Summary of the Invention

[0004] An object of the present invention is to provide a switch device operating mechanism for use in a narrow space, so as to solve the problems raised in the above background technology.

[0005] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0006] A switch device operating mechanism used in narrow spaces includes: a switch body, a mounting groove is provided on one side of the switch body, an operating member and a support member are rotatably connected in the mounting groove, the operating member and the support member are respectively provided with an operating member rotation point and a support member rotation point, the operating member and the support member are rotatably connected to the switch body by bolts inserted into the operating member rotation point and the support member rotation point, a connecting rod is connected between the operating member and the support member, a moving contact is rotatably connected to one side of the support member, a static contact that matches the position of the moving contact is fixedly provided inside the mounting groove, a limiting boss for limiting the support block is fixedly installed above the support block, and a fixing mechanism is also provided between the support member and the operating member.

[0007] Furthermore, the rotation point of the operating member, the rotation point of the supporting member, and the upper surface of the static contact are substantially on both sides of a straight line.

[0008] Furthermore, protruding steps are symmetrically provided on both sides of the operating member.

[0009] Furthermore, the support member is provided with a sliding groove, which is long and has arc-shaped ends. One end of the connecting rod is rotatably connected to the support member through the sliding groove. When the switch is opened / closed, the connecting rod stays at the lower part of the sliding groove. When the switch is pulled out of the installation groove, the connecting rod is at the upper part of the sliding groove.

[0010] Furthermore, the support member is provided with a groove for installing the moving contact, and the groove has two raised arc edges formed in the groove. The moving contact is rotatably connected to the support member by inserting one end into the groove, and one end of the moving contact is attached to the two raised arc edges.

[0013] The present invention reduces the space occupied by the mechanism in the switch main body device; and the operating member can have three states of closing, opening and pulling out, which can clearly indicate the state of the switch. At the same time, the operating member can serve as a force point for pulling out the switch, which is convenient for operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: See Figures 1 to 6 The present invention provides a technical solution: a switch device operating mechanism used in a narrow space, comprising: a switch body 1, a mounting groove 13 is opened on one side of the switch body 1, an operating member 2 and a support member 4 are rotatably connected in the mounting groove 13, the operating member 2 and the support member 4 are respectively provided with an operating member rotation point 5 and a support member rotation point 6, the operating member 2 and the support member 4 are rotatably connected to the switch body 1 by bolts inserted into the operating member rotation point 5 and the support member rotation point 6, a connecting rod 3 is connected between the operating member 2 and the support member 4, a moving contact 9 is rotatably connected to one side of the support member 4, a static contact 10 that matches the position of the moving contact is fixedly provided inside the mounting groove 13, a limiting boss 8 for limiting the support block 4 is fixedly installed above the support block 4, and a fixing mechanism is also provided between the support member 4 and the operating member 2.

[0023] The operating member's rotation point 5, the support member's rotation point 6, and the top surface of the static contact 10 are essentially aligned on opposite sides of a straight line. Within a certain range of operating member rotation, the mechanism's open, closed, and disconnected states are angularly distributed, and the product's operating member can only remain stationary in the open and closed positions.

[0024] Among them, the support member 4 is provided with a slide groove 7, which is long and has arc-shaped ends. One end of the connecting rod 3 is rotatably connected to the support member 4 through the slide groove 7. When the switch is opened / closed, the connecting rod 3 stays at the lower part of the slide groove 7. When the switch is pulled out of the mounting groove 13, the connecting rod 3 is at the upper part of the slide groove 7. When the switch is opened / closed, the connecting rod 3 stays at the lower part of the slide groove 7. The support member 4 of the mechanism is in a corresponding position according to the state of the mechanism. When the product is in the pulled-out state, the support member 4 does not move with the movement of the operating member 2. The connecting rod 3 cooperating with the operating member 2 moves to the upper part of the slide groove 7. When the operating member 2 returns to the opening position, the connecting rod 3 of the mechanism moves from the upper part to the lower part of the slide groove 7.

[0025] Among them, the support member 4 is provided with a groove 14 for installing the moving contact 9, and the groove 14 is formed with two raised arc edges. The moving contact 9 is rotatably connected to the support member 4 by inserting one end into the groove 14, and one end of the moving contact 9 is attached to the two raised arc edges. The handheld operating member 3 moves clockwise to move the moving contact 9 toward the closed state. The force of the operating member 2 is transmitted to the support member 4 through the connecting rod 3, thereby driving the moving contact 9 and the static contact 10 to close. After the moving and static contacts are in contact, the mechanism will continue to move. At this time The moving contact 9 will no longer move with the contact bracket, but will rotate around the two arc edges of the support 4 and against the support 4, and the contact spring will provide the contact pressure required by the moving contact 9. At the same time, it has an angled feature for applying a leftward force to the contact to maintain the force balance in the closed state; when opening the switch, the support 4 relies on the restoring force of the mechanism spring 12 until the support 4 rests against the limit boss 8 of the housing. This is the farthest point of the contact opening, and the moving contact 9 also returns to its initial position.

[0026] Among them, the fixing mechanism includes a fixing buckle 11 connected to the operating part 2 and a mechanism spring 12 connected to the fixing buckle 11. There are protruding steps symmetrically arranged on both sides of the operating part 2. When it is pulled out, it is necessary to press the operating part 2 by hand and rotate it counterclockwise from the opening position to a certain angle, cooperate with the fixing buckle 11 to unbutton, and then use the protruding steps on both sides of the operating part 2 to pull out the product. When the hand releases the force in the unbuttoning position, the mechanism spring 12 on the fixing buckle 11 drives the fixing buckle 11 to link the operating part 2, so that the operating part 2 rotates clockwise back to the opening position instantaneously.

[0027] Working principle: During the use of the present invention, when closing the circuit breaker, the hand-held operating member 2 moves clockwise to move the moving contact 9 toward the closed state, and the force of the operating member 2 is transmitted to the support member 4 through the connecting rod 3, thereby driving the moving contact 9 and the static contact 10 to close the circuit breaker; after the moving and static contacts are in contact, the mechanism will continue to move, and the moving contact 9 will no longer follow the movement of the contact bracket, but will circle the moving contact 9 against the two arc edges of the support member 4 and rotate in the groove 14 reserved by the support member 4. The contact spring then provides the contact pressure required by the moving contact 9, and at the same time, it has an angled feature for applying a leftward force to the contact to maintain a force balance in the closed state; when opening the circuit breaker, the support member 4 relies on the restoring force of the mechanism spring 12 until the support When the switch is pulled out, the operating member 2 needs to be pressed down by hand and rotated counterclockwise by a certain angle from the opening position to cooperate with the fixing buckle 11 to unfasten it, and then use the protruding steps on both sides of the operating member 2 to pull out the product. When the hand releases the force in the unfastened position, the mechanism spring 12 on the fixing buckle 11 drives the fixing buckle 11 and then links the operating member 2, so that the operating member 2 rotates back to the opening position instantaneously. This device reduces the space occupied by the mechanism in the switch body 1 device; and the operating member 2 can have three states: closing, opening and pulling out, which can clearly indicate the state of the switch. At the same time, the operating member 2 can be used as the fulcrum for pulling out the switch, which is convenient for operation.
