Description

Technical Field

[0001] The utility model relates to a security measure for a switch cabinet used for power supply of a public power grid, in particular to a shielding device for a movable slot of an unlocking handle on a panel of a ring network cabinet mechanism room. Background Art

[0002] The existing ring main unit for public power grid power supply must meet the requirements of IP4X housing protection level of the new national standard, and the ring main unit housing must be able to prevent the entry of solid foreign objects with a diameter greater than or equal to 1.0 mm. The isolating switch operation hole, grounding switch operation hole, energy storage operation hole, opening button hole and closing button hole on the mechanism room panel of the ring main unit currently produced by the applicant are all provided with plastic covers with padlock holes. However, the unlocking handle moving slot hole on the mechanism room panel used to control the unlocking of the cable room door must be exposed because the unlocking handle needs to be moved on it at all times. However, it is not easy to close the unlocking handle moving slot hole part that is not occupied during the movement of the unlocking handle. Therefore, the unlocking handle moving slot hole on the mechanism room panel of the existing ring main unit currently produced by the applicant has an exposed and unclosed part, which does not meet the requirements of the new national standard. Summary of the invention

[0003] In order to overcome the problem that the applicant's existing ring main unit has an unlocking handle movable slot on the mechanism chamber panel that always has an exposed and unclosed part, which fails to meet the requirements of the new national standard, the purpose of the utility model is to provide an improved unlocking handle movable slot shielding device on the mechanism chamber panel of the ring main unit, which can overcome the defects of the prior art.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a unlocking handle moving slot hole covering device on the ring network cabinet mechanism chamber panel, comprising an unlocking handle installed and matched with the unlocking handle moving slot hole on the ring network cabinet mechanism chamber panel, a lock seat fixed on the ring network cabinet body behind the ring network cabinet mechanism chamber panel, and a lock that is rotatably matched with the lock seat through a pin shaft, wherein the rear part of the unlocking handle passes through the front side hole of the lock seat and is fixedly connected with the driving end of the lock, and is characterized in that: it also includes a slot hole covering member matched with the unlocking handle, the slot hole covering member has a front side covering plate, a left side connecting plate and a right side connecting plate, the front side covering plate is slidably matched with the unlocking handle on the rear side of the ring network cabinet mechanism chamber panel through the handle hole thereon, the left side connecting plate is slidably matched with the left side of the pin shaft through the left long hole thereon, and the right side connecting plate is slidably matched with the right side of the pin shaft through the right long hole thereon.

[0005] The area size of the front side shielding plate in the above technical solution can be greater than or equal to 45mm in length and greater than or equal to 15mm in width, so that when the unlocking handle is in any position of the unlocking handle moving slot, the front side shielding plate is sufficient to cover the exposed part of the unlocking handle moving slot.

[0006] The left long hole and the right long hole described in the above technical solution can both be long holes extending vertically.

[0007] The front opening of the locking seat described in the above technical solution can be a long hole extending vertically.

[0008] The beneficial effect of the utility model is that: since it includes a slot hole covering member that is matched with the unlocking handle, the slot hole covering member has a front covering plate, a left connecting plate and a right connecting plate, the front covering plate is slidably matched with the unlocking handle on the rear side of the ring network cabinet mechanism chamber panel by the handle hole thereon, the left connecting plate is slidably matched with the left side of the pin shaft by the left long hole thereon, and the right connecting plate is slidably matched with the right side of the pin shaft by the right long hole thereon, so when the unlocking handle moves up and down in the unlocking handle moving slot hole, the slot hole covering member will follow the unlocking handle on the rear side of the ring network cabinet mechanism chamber panel to make vertical synchronous up and down movement, and the front covering plate of the slot hole covering member will always cover the exposed part of the unlocking handle moving slot hole, so that the applicant's existing ring network cabinet can meet the IP4X housing protection level requirements of the new national standard. The left connecting plate is slidably engaged with the left side of the pin shaft, and the right connecting plate is slidably engaged with the right side of the pin shaft, so that the slot hole covering member will not rotate on the unlocking handle, so that the front covering plate keeps its shape unchanged when following the unlocking handle to move up and down vertically synchronously, so as to achieve a good covering effect.
