Description

Technical Field

[0001] This utility model relates to a baffle structure, specifically a double-protection operating hole baffle structure. Background Technology

[0002] The operating ports of circuit breakers, isolating switches, and grounding switches in 10kV switchgear must be equipped with padlock devices. The padlock hole diameter is 8mm. When the lock is engaged, it must prevent the operating handle from being inserted into the operating port and must not obscure the wiring diagram and markings on the cabinet panel. The five-proof interlocking components of the operating ports must ensure an IP4X protection level.

[0003] Currently, most manufacturers use single-protection baffles for the operating holes, which are opened by rotation. The gap between the first and second baffles is controlled by the tightness of the nut. However, in actual production, the baffle may become loose due to nut rotation or body deformation, making it difficult to guarantee the IP4X protection level. Therefore, it is necessary to optimize the existing technology. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a dual-protection operating hole baffle structure.

[0005] This utility model relates to a dual-protection operating hole baffle structure, comprising a first baffle disposed on one side of the operating hole and a second baffle disposed on the other side of the operating hole and moving synchronously with the first baffle. The operating hole is provided with a first fixing hole and a rotation limiting member on its outer periphery. The first baffle and the second baffle are provided with a second fixing hole at a position corresponding to the first fixing hole. A rotating shaft is provided in the first fixing hole and the second fixing hole. The first baffle and the second baffle are hinged to both sides of the operating hole through the rotating shaft. The first baffle and the second baffle can simultaneously close or open the operating hole.

[0006] Furthermore, the operating hole is provided on the operating panel, and the dual-protection operating hole baffle structure also includes a first baffle fixing plate disposed between the operating panel and the first baffle. The rotation limiting member is a first locking hole plate disposed perpendicular to the first baffle fixing plate. The first baffle is provided with a second locking hole plate that cooperates with the first locking hole plate. When the first baffle covers the operating hole, the first locking hole plate and the second locking hole plate cooperate to fix the first baffle.

[0007] Furthermore, the dual-protection operating hole baffle structure also includes a second baffle pad disposed between the operating panel and the second baffle. The second baffle pad is fixed on the operating panel, and both the first baffle fixing plate and the second baffle pad are provided with windows that match the operating hole.

[0008] Furthermore, the first baffle fixing plate and the second baffle pad are provided with several countersunk holes at corresponding positions on the outer periphery of the window, which are fixed with countersunk screws. The first baffle fixing plate and the second baffle pad are fixed on the operation panel by countersunk screws.

[0009] Furthermore, the rotating shaft is provided with a limiting connection structure, and the first baffle and the second baffle are respectively limited to the rotating shaft through the limiting connection structure.

[0010] Furthermore, the limiting connection structure has one or more cutting surfaces on the rotating shaft, and the shape of the second fixing hole of the first baffle and the second baffle matches the cross-sectional shape of the rotating shaft with the cutting surface.

[0011] Furthermore, the limiting connection structure is a bushing sleeved on the rotating shaft, and the first baffle and the second baffle are interference-fitted with the bushing.

[0012] Compared with the prior art, the beneficial effects of this utility model are: adopting a double protective baffle form, the first baffle and the second baffle are driven to rotate synchronously through a correspondingly designed rotating shaft, the gap between the first baffle and the second baffle and the operation panel is controllable, ensuring the protection level of IP4X. Even if the outer first baffle is accidentally deformed after multiple operation of the baffle structure, causing the gap between the first baffle and the first baffle fixing plate to fail to meet the protection requirements such as IP4X, the inner second baffle can still ensure the protection level.

[0020] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a particular order.

[0021] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1-6 As shown, the present invention relates to a double-protection operating hole baffle structure, which is applied to a switch cabinet. The switch cabinet is provided with an operating panel 1, and an operating hole is provided on the operating panel 1. The double-protection operating hole baffle structure includes a first baffle 3 provided on one side of the operating hole and a second baffle 5 provided on the other side of the operating hole, which moves synchronously with the first baffle 3. The operating hole is provided with a first fixing hole and a rotation limiting member on its outer periphery. The first baffle 3 and the second baffle 5 are provided with a second fixing hole 502 at the corresponding positions of the first fixing hole. A rotating shaft 6 is provided in the first fixing hole and the second fixing hole. The first baffle 3 and the second baffle 5 are hinged to both sides of the operating hole through the rotating shaft 6. The first baffle 3 and the second baffle 5 can rotate clockwise or counterclockwise along a surface parallel to the operating panel 1, thereby simultaneously closing or opening the operating hole.

[0024] Preferably, the dual-protection operating hole baffle structure further includes a first baffle fixing plate 2 disposed between the operating panel and the first baffle 3. The rotation limiting member is a first locking hole plate 201 disposed perpendicularly to the first baffle fixing plate 2. The first baffle 3 is provided with a second locking hole plate 301 that cooperates with the first locking hole plate 201. When the first baffle 3 covers the operating hole, the first locking hole plate 201 and the second locking hole plate 301 cooperate to fix the first baffle 3. The locking hole 202 on the first locking hole plate 201 and the locking hole on the second locking hole plate 301 are used to install a padlock.

[0025] Preferably, the dual-protection operating hole baffle structure further includes a second baffle pad 4 disposed between the operating panel 1 and the second baffle 5. The second baffle pad 4 is fixed on the operating panel 1, and both the first baffle fixing plate 2 and the second baffle pad 4 are provided with windows 402 that match the operating hole.

[0026] This utility model adopts a double protective baffle design. The first baffle and the second baffle are driven to rotate synchronously by a correspondingly designed rotating shaft. The gap between the first baffle, the second baffle and the operation panel is controllable, ensuring the protection level of IP4X. Even if the outer first baffle is accidentally deformed after multiple operations of the baffle structure, causing the gap between the first baffle and the first baffle fixing plate to fail to meet the protection requirements such as IP4X, the inner second baffle can still ensure the protection level.

[0027] like Figure 1 and Figure 4 As shown, in this example, for ease of fixation, three bolt fixing holes 203 and 401 are evenly provided around the window of the first baffle fixing plate 2 and the second baffle pad 4. Fixing holes are provided at corresponding positions on the operation panel 1. The first baffle fixing plate 2 and the second baffle pad 4 are fixed by screws that pass through the bolt fixing holes and the fixing holes. Preferably, in order to prevent the screws from interfering with the rotating first baffle 3 and the second baffle 5, the three bolt fixing holes 203 and 401 around the window of the first baffle fixing plate 2 and the second baffle pad 4 are countersunk holes, and the screws are fixed by countersunk screws.

[0028] At this time, when there is no padlock, the first baffle 3 and the second baffle 5 are heavy at the end near the padlock plate. Due to gravity, they will automatically rotate downwards to open the operating hole. When it is necessary to close the operating hole, simply rotate clockwise or counterclockwise to align the first lock hole plate and the second lock hole plate, and then lock them with the lock.

[0029] In a preferred embodiment of this utility model, the bolt fixing holes 203 and 401 are divided into three, one of which is located at the top and the other two are located on the left and right sides, below the first baffle. The bolt fixing holes of the two bolt fixing holes are respectively fixed by screws and nuts protruding from the bolt fixing holes, thereby limiting the clockwise and counterclockwise rotation angle of the first baffle, making it easier to operate.

[0030] As another improved embodiment of this utility model, the screw and nut protruding from the first baffle fixing plate 2 can be replaced by a limiting plate provided on the first baffle fixing plate 2, thereby limiting the opening angle of the first baffle.

[0031] like Figure 5 As shown, the second baffle 5 is a circular plate with an area slightly larger than that of the operating hole. A fixed end 501 protrudes from one side of the circular plate, and the second fixed hole 502 is disposed on the fixed end 501.

[0032] like Figure 6 As shown, in order to achieve synchronous rotation of the first baffle 3 and the second baffle 5, a limiting connection structure is provided on the rotation shaft. The first baffle 3 and the second baffle 5 are respectively connected to the rotation shaft through the limiting connection structure.

[0033] In this example, the rotating shaft 6 includes a base 601 with a slightly larger diameter and a rotating shaft body 602 with a slightly smaller diameter mounted on the base 601. Two first cut surfaces 604 are provided on the side of the base 601 near the rotating shaft body 602, making the first cross-section of this portion of the base 601 capsule-shaped. The shape of the second fixing hole of the second baffle 5 matches the shape of the first cross-section and is fitted onto the base with the first cut surfaces 604. Two second cut surfaces 603 are provided on the end of the rotating shaft body 602 away from the base 601, making the second cross-section of this portion of the rotating shaft body 602 capsule-shaped. The shape of the second fixing hole of the first baffle 3 matches the shape of the second cross-section and is fitted onto the rotating shaft body 602 with the second cut surfaces 603. The rotating shaft body between the first cut surfaces 604 and 603 engages with the first fixing hole of the operation panel. Of course, this example could also use only one cut surface to fully meet the synchronous rotation requirement, and the first cut surfaces 604 and 603 could also be replaced by structures with cross-sections of triangles, squares, ellipses, or other shapes.

[0034] As another embodiment of this utility model, the limiting connection structure of this example can also be configured as a bushing sleeved on the rotating shaft, with the first baffle and the second baffle having an interference fit with the bushing.

[0035] In this example, the outer first baffle of the control panel has a locking hole, and the inner second baffle pad is connected to the mechanism chamber panel by bolts. After assembling all components on the control panel, both the inner second baffle and the outer first baffle are fixed in their positions and can rotate. To operate the mechanism, rotate the first baffle clockwise by hand; the second baffle will rotate synchronously. After operation, rotate the first baffle counterclockwise by hand; the second baffle will rotate synchronously to close the mechanism. When closed, the first and second locking hole plates are aligned and can be locked with the lock.

[0036] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
