DETAILED DESCRIPTION
[0025] The specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings, but the description of the embodiments is not a limitation of the technical solution. Any changes in form rather than substance based on the concept of the present invention should be regarded as the protection scope of the present invention.
[0026] In the following description, all concepts related to directionality or orientation such as up, down, left, right, front and back are based on the positions shown in the corresponding drawings. They are only used to facilitate the description of the technical solution provided by the utility model and simplify the description in conjunction with the drawings, and therefore cannot be understood as a special limitation on the technical solution provided by the utility model.
[0027] See also Figure 1 , Figure 2 The switch includes an operating mechanism 1, on which a switch-off locking device 2 and an electromagnet assembly 3 are installed. Specifically, the switch-off locking device 2 and the electromagnet assembly 3 are both installed above the operating mechanism 1.
[0028] The operating mechanism 1 is a driving component of the switch, which is used to drive the contact system (not shown in the figure) of the switch to operate. After the contact system operates, the switch can be closed or separated, thereby controlling the on and off of the current. Therefore, the operating mechanism 1 is equivalent to the driving component inside the switch.
[0029] The operating mechanism 1 comprises a pair of spaced-apart side plates 11 and a top plate 12 located above the pair of side plates 11, so that the pair of side plates 11 and the top plate 12 form an outer shell of the operating mechanism 1. A switch-off half-shaft 13 is also rotatably arranged between the pair of side plates 11, and the switch-off half-shaft 13 can trigger the operating mechanism 1 to perform a switch-off action after being driven to rotate, so that the operating mechanism 1 drives the contact system to perform a disconnection action.
[0030] The electromagnet assembly 3 is mounted on the top plate 12 and directly above the operating mechanism 1. The opening lock device 2 is also mounted on the top plate 12 of the operating mechanism 1, but the opening lock device 2 is located on one side of the electromagnet assembly 3.
[0031] The electromagnet assembly 3 generally includes a plurality of electromagnets 32, wherein the electromagnet 32 includes a shunt electromagnet and a closing electromagnet. Preferably, the electromagnet 32 also includes an undervoltage electromagnet. The shunt electromagnet and the closing electromagnet are used to connect with external signals, that is, to trigger the operation mechanism 1 to act, specifically to close or open the switch, by receiving external signals. The undervoltage electromagnet is used to detect the voltage signal carrying the current, and when the voltage is too low, the operating mechanism 1 is triggered to cut off the current.
[0032] The opening locking device 2 is used to lock the operating mechanism 1 in the opening state, that is, to lock the operating mechanism 1 in the opening state and prevent it from closing, thereby improving safety.
[0033] like Figure 3 The gate opening locking device 2 includes a bracket 21, a sliding plate 22, a lock core 23 and a key 24. The bracket 21 is fixedly mounted on the top plate 12, the sliding plate 22 is slidably arranged, and the lock core 23 is mounted on the bracket 21. The key 24 cooperates with the lock core 23. Specifically, after the operator inserts the corresponding key 24 into the lock hole in the middle of the lock core 23, the operator operates by turning the key 24.
[0034] The top plate 12 is provided with a clearance hole 121, which is adapted to the shape of the sliding plate 22, that is, the sliding plate 22 is sunk below the top plate 12. The reason is that the sliding plate 22 needs to contact and cooperate with the opening half shaft 13 also located below the top plate 12.
[0035] Combination Figure 1The electromagnet assembly 3 further includes a mounting base plate 31, and the electromagnet 32 is mounted above the mounting base plate 31 and fixed by a fixing belt.
[0036] A snap-fitting boss 311 extends out from the bottom of the mounting base 31. The snap-fitting boss 311 cooperates with the sliding plate 22 to achieve the sliding setting of the sliding plate 22. Specifically, the snap-fitting boss 311 is divided into two groups, and each group of snap-fitting bosses 311 includes a pair of snap-fitting bosses 311, and the pair of snap-fitting bosses 311 are arranged back to back, and the protruding end of each snap-fitting boss 311 is in the shape of a snap joint. The snap-fitting boss 311 is snapped into the sliding plate 22, so that the sliding plate 22 can slide relative to the snap-fitting boss 311, that is, slide relative to the mounting base 31. Since the mounting base 31 is fixedly mounted on the top plate 12, the sliding plate 22 can achieve a sliding connection with the top plate 12.
[0037] The bracket 21 is a bent plate. The bracket 21 can be formed by bending a metal plate or by integrally forming a plastic part.
[0038] Specifically, the bracket 21 is fixed on the top plate 12, and more specifically, is fixed on the top plate 12 by screws. A lock hole is also provided on the bracket 21, and the lock hole is used to install the lock core 23.
[0039] like Figure 4 , Figure 5 , Figure 6 , Figure 7 The sliding plate 22 includes a driving end 221, a sliding groove 222 and a toggle groove 223. The driving end 221 is used to cooperate with the opening half shaft 13, while the sliding groove 222 cooperates with the clamping boss 311, and the toggle groove 223 cooperates with the paddle 231 on the lock core 23.
[0040] The opening half shaft 13 comprises a half shaft notch 131, a first pushing end 132 and a second pushing end 133. The half shaft notch 131 is located in the middle of the opening half shaft 13, and the first pushing end 132 and the second pushing end 133 are located at both ends of the opening half shaft 13. The first pushing end 132 is pushed and matched with the driving end 221, that is, when the driving end 221 slides left and right, the driving end 221 can move the first pushing end 132, thereby driving the opening half shaft 13 to rotate.
[0041] The sliding groove 222 is a T-shaped groove. Thus, the clamping boss 311 is conveniently inserted, that is, the clamping boss 311 is inserted from the expanded opening and slides to the narrow opening to achieve sliding fit between the two. During the travel of the sliding plate 22, the clamping boss 311 is located at the narrow opening, ensuring the reliability of sliding fit. The corresponding clamping boss 311 is two groups, i.e., two pairs, and the sliding grooves 222 are also two, so that a better sliding fit effect can be achieved.
[0042] The toggle groove 223 corresponds to the lower side of the paddle 231 . When the paddle 231 rotates, the sliding plate 22 can be toggled to perform a reciprocating motion by cooperating with the toggle groove 223 .
[0043] like Figure 8 Specifically, the paddle 231 is in the shape of a boomerang, and includes a first toggle end 2311 and a second toggle end 2312. A clamping opening 2313 is provided at the rotation center of the paddle 231. In this embodiment, the clamping opening 2313 is a waist-shaped hole, and of course, it can also be other shapes, such as a hexagonal, square, and other shapes that can achieve synchronous rotation. More specifically, the first toggle end 2311 pushes the inner side of the toggle groove 223, and the second toggle end 2312 pushes the end 224 of the sliding plate 22. More preferably, a protruding oblique boss is provided on the sliding plate 22 corresponding to the first toggle end 2311 and the second toggle end 2312, so as to better meet the rotation characteristics of the paddle 231.
[0044] The driving edge 2211 of the driving end 221 is in an arc shape or a bevel shape, and the driving edge 2211 pushes the first pushing end 132. Therefore, when the opening gate half shaft 13 is in the initial position, the driving end 221 can also lock the opening gate half shaft 13, that is, when the driving end 221 locks the opening gate half shaft 13, the opening gate half shaft 13 can be moved, thereby eliminating the existing operation process of driving the opening gate half shaft 13 to rotate and then lock it by external means, such as by pressing the opening gate button to realize the rotation of the opening gate half shaft 13. This structural setting simplifies the operation steps of the operator, making it easier for the operator to perform the opening gate locking operation. This also improves the core competitiveness of the product and has a huge market effect.
[0045] goodbye Figures 4 to 6 , showing the entire working process of the opening lock device. The following description is based on the direction shown in the figure. When the operator needs to perform a locking action, the key 24 is inserted and turned, the shaft in the lock cylinder 23 rotates, driving the paddle 231 to rotate clockwise, the first paddle end 2311 drives the sliding plate 22 to slide to the left, and the driving end 221 pushes the pushing end 132 to rotate, so that the opening half shaft 13 moves.
[0046] Figure 5 , the driving end 221 presses the pushing end 132, and the opening half shaft 13 is in the opening state, that is, the operating mechanism 1 is locked in the opening state.
[0047] Figure 6 In the above state, the key 24 is rotated in the opposite direction, the second toggle end 2312 toggles the sliding plate 22 to the right, the driving end 221 leaves the pushing end 132, the opening half shaft 13 is reset due to its own restoring force, and the opening state of the operating mechanism 1 is unlocked.
