DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] See also Figure 1 and 2 The utility model provides a visual isolation knife switch, involving a motor 100 and a drawer switch 200, wherein the motor 100 is connected to the outgoing line side of the isolation knife switch 300 through a cable, and the incoming line side of the isolation knife switch 300 is connected to the outgoing line side of the drawer switch 200 through a cable;
[0023] The isolating knife switch 300 comprises a box body 301 , in which a knife switch 302 is arranged, and the knife switch 302 is controlled to be opened and closed by an operating handle 303 .
[0024] This embodiment adds a visible knife switch between the motor 100 and the drawer switch 200 to prevent the operator from pushing or pulling out the drawer switch 200, thereby improving operational safety and reliability.
[0025] In one embodiment, see Figure 2 An electromagnetic lock 304 is provided in the box body 301 , and the electromagnetic lock 304 is connected to the operating handle 303 of the knife switch 302 , and the electromagnetic lock 304 is powered by the power supply on the outgoing line side of the drawer switch 200 .
[0026] This embodiment is configured to ensure that when the drawer switch 200 is in the closed position, it is strictly forbidden to open the knife switch 302, thereby improving safety.
[0027] In one embodiment, see Figure 2 , a visual window 305 and a live indicator light are provided on the box 301 for observing the state of the knife switch 302. In this embodiment, the staff can directly observe the state of the knife switch in the box 301 through the visual window 305, which is convenient for the staff to understand in time and help judge the subsequent operation.
[0028] In one embodiment, see Figure 3-5 The operating handle 303 is connected to the control rod of the knife switch 302 through the telescopic structure 3031, and the operating handle 303 is embedded with circumferentially distributed balls 3032. The box body 301 is provided with mutually connected limiting grooves 3033 and rolling grooves 3034. The balls 3032 follow the operating handle 303 to move back and forth between the limiting grooves 3033 and the rolling grooves 3034.
[0029] The present embodiment is configured such that when the staff needs to operate the knife switch 302, the staff first pulls the operating handle 303 outward for a distance through the telescopic structure 3031, so that the ball 3032 moves from the limiting groove 3033 to the rolling groove 3034, and then rotates the operating handle 303, which can save effort to control the operating handle 303 and avoid the problem of damage to the plastic parts of the operating handle 303 and long-term and vigorous use of the operating handle 303.
[0030] In one embodiment, see Figure 3-5 The limiting groove 3033 is provided with a ball groove adapted to the ball 3032, and the rolling groove 3034 is an annular groove. This embodiment is arranged so that when the ball 3032 is in the limiting groove 3033, the operating handle 303 can be limited to rotate, and when in the rolling groove 3034, the operating handle 303 can be rotated with less effort.
[0031] In one embodiment, see Figure 6The telescopic structure 3031 includes a sleeve 30311, on which an elastic stop block 30312 is disposed, and on the box body 301, a slot adapted to the elastic stop block 30312 is provided. In this embodiment, when the staff controls the operating handle 303, when the operating handle 303 is pulled outward, it can stop and limit at a specified distance, and then the operating handle 303 can be rotated to control the opening and closing of the knife switch 302.
[0032] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.
[0033] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that satisfy both A and B. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.
