Description

Technical Field

[0001] The utility model relates to the technical field of static contact isolation baffle locking devices, in particular to a static contact isolation baffle locking device for a switch cabinet. Background Art

[0002] The switch cabinet static contact isolation baffle locking device is an important device used to ensure the safe operation of the switch cabinet. It can ensure that the static contact isolation baffle cannot be opened at will when the switch cabinet is energized, avoiding injuries caused by operator contact with live parts, and can also reduce the risk of safety accidents such as electric shock and short circuit caused by misoperation. The isolation baffle locking device plays a key role in the safety protection of the switch cabinet and can effectively improve the reliability and safety of the switch cabinet operation.

[0003] The existing locking device generally adopts a spring and a guide rod to achieve the purpose of preventing opening. This method is easily affected by the aging of the spring and the rebound effect. Long-term use will cause the isolation plate to rebound incompletely, and part of the static contact will leak out, and the dustproof effect is general. Therefore, it is necessary to invent a more reliable static contact isolation baffle locking device with good sealing effect. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model develops a locking device for the static contact isolation baffle of a switch cabinet, which can achieve a good dust prevention effect. At the same time, the angle formed by the first slide groove and the slide rail cooperates with the upper clip and the lower clip to improve the reliability of the isolation plate after locking, making it less likely to fall off accidentally.

[0005] The technical solution to the technical problem solved by the utility model is: a switch cabinet static contact isolation baffle locking device, comprising a contact box, a static contact, a slide rail and an isolation plate, the static contact is installed in the contact box, the slide rails are symmetrically arranged on both sides of the contact box, a first slide groove and a second slide groove are arranged on the slide rails, two sliders are respectively arranged on both sides of the isolation plate, the spacing between the two sliders is the same as the distance between the end of the first slide groove and the end of the second slide groove, and the slider is slidably connected in the slide rail.

[0006] Preferably, the first chute end and the second chute end are located on the same straight line in the vertical direction.

[0007] Preferably, the first sliding groove and the sliding rail form an acute angle in a direction away from the second sliding groove.

[0008] Preferably, the second slide groove is divided into a curved section and a straight section, the curved section forms an acute angle with the slide rail in a direction away from the first slide groove, and the straight section is parallel to the slide rail.

[0009] Preferably, a handle is hinged on the isolation plate.

[0010] Preferably, the contact box is hinged with an upper buckle at a position close to the top of one side of the slide rail.

[0011] Preferably, a lower buckle is hinged on one side of the lower surface of the contact box close to the slide rail.

[0012] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0013] 1. By designing the first slide groove to form an acute angle with the direction in which the slide rail moves away from the second slide groove, the isolation plate can be made more stable and less likely to fall off when in a closed state;

[0014] 2. By designing the second slide groove into two sections, a curved section and a straight section, the isolation plate can be embedded in the contact box when in a closed state, which improves stability and also has a good dust-proof effect;

[0015] 3. By setting an upper buckle, when the isolation plate is in a closed state, the upper buckle is rotated to clamp the isolation plate, so that the isolation plate can be made more stable;

[0016] 4. By setting the lower buckle, the isolation plate is provided with the last protective barrier. When the isolation plate is in a closed state, the lower buckle is rotated to the direction toward the outside of the outlet box. Even if a failure occurs, the isolation plate can be prevented from falling, thus better ensuring the safety of the operator;

[0017] 5. By setting a handle on the isolation board, it can be easily pulled up and down. At the same time, the handle is hinged on the isolation board. When not in use, it can be rotated to fit tightly against the isolation board to avoid accidental operation that hooks the isolation board, thereby accidentally opening the isolation board and causing safety accidents.

[0024] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0025] Example 1

[0026] See also Figures 1 to 5 A switch cabinet static contact isolation baffle locking device comprises a contact box 1, a static contact 2, a slide rail 3 and an isolation plate 4, wherein the static contact 2 is installed in the contact box 1, and the slide rail 3 is symmetrically arranged on both sides of the contact box 1, and a first slide groove 31 and a second slide groove 32 are arranged on the slide rail 3, and two sliders 42 are respectively arranged on both sides of the isolation plate 4, and the spacing between the two sliders 42 is the same as the distance between the end of the first slide groove 31 and the end of the second slide groove 32, and the slider 42 is slidably connected in the slide rail 3, and the two slide rails 3 can also be installed on the outside, and a groove matching the slide rail 3 is processed on the side of the contact box 1, so that a better sealing effect can be achieved, and it is used in the case of high requirements for dustproof and waterproof.

[0027] like Figure 5 As shown, the end of the first slide slot 31 and the end of the second slide slot 32 are located on the same straight line in the vertical direction.

[0028] like Figure 5 As shown, the first slide groove 31 and the slide rail 3 form an acute angle in the direction away from the second slide groove 32. The angle of the acute angle depends on the distance from the end of the second slide groove 32 to the end of the first slide groove 31. This distance is the radius, and the end close to the first slide groove 31 close to the slide rail 3 should also be equal to this radius.

[0029] like Figure 5 As shown, the second slide groove 32 is divided into a curved section 321 and a straight section 322 . The curved section 321 forms an acute angle with the slide rail 3 in a direction away from the first slide groove 31 , and the straight section 322 is parallel to the slide rail 3 .

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, a handle 41 is hinged on the isolation plate 4.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, the contact box 1 is hinged with an upper buckle 5 at the top of one side close to the slide rail 3, and the upper buckle 5 can be arranged in an array.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, a lower buckle 6 is hinged on one side of the lower surface of the contact box 1 close to the slide rail 3, and the lower buckle 6 can be arranged in an array.

[0033] Principle and operation process

[0034] The utility model provides a more stable and reliable locking device for the isolation plate 4 of the contact box 1, and the device is installed in the switch cabinet as a whole. By designing the first slide groove 31 to form an acute angle with the direction in which the slide rail 3 is away from the second slide groove 32, the utility model can make it difficult to pull out the lower slide block 42 after entering the first slide groove 31 when the isolation plate 4 is pulled up and in a closed state, and the locking is more stable and not easy to fall off; the second slide groove 32 is designed to have a curved section 321 and a straight section 322, and when the isolation plate 4 is pulled up, the slide block 42 above the isolation plate 4 will pass through the curved section 321 and extend a certain distance into the contact box 1. When the slide block 42 above the isolation plate 4 slides to the end of the second slide groove 32, the slide block 42 below the isolation plate 4 is pushed into the first slide groove 31, so that the isolation plate 4 can be embedded in the contact box 1 when it is in a closed state, while improving stability, it also has a good dustproof effect.

[0035] After the isolation plate 4 is pulled up and is in a closed state, the upper buckle 5 is rotated to clamp the isolation plate 4, and the lower buckle 6 is rotated to provide the isolation plate 4 with a last protective barrier. When the isolation plate 4 is in a closed state, the lower buckle 6 is rotated to the direction toward the outside of the head box. Even if a failure occurs, the isolation plate 4 can be prevented from falling, thereby better ensuring the safety of the operator; the hinged handle 41 on the isolation plate 4 can facilitate pulling the isolation plate 4 up and down or pushing and pulling the isolation plate 4 horizontally. When not in use, it can be rotated to a state close to the isolation plate 4 to avoid accidental operation to hook the isolation plate 4, thereby pulling the isolation plate 4 down and causing a safety accident.

[0036] When the isolation plate 4 needs to be opened, the upper buckle 5 and the lower buckle 6 are rotated to put the isolation plate 4 in an unlocked state, the isolation plate 4 is pulled, the lower slider 42 is pulled out from the first slide groove 31, and then the isolation plate 4 is pulled downward to complete the opening operation.

[0037] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
