The invention discloses a portable SF6 gas density measuring device with convenient locking and covering. The structure of the device comprises a closed box cover, a measuring body and a storage box body. The measuring body is inlaid in the middle portion of the top end of the storage box body which is in clearance fit with the measuring body, and the rear side of the top end of the storage box body is in hinge connection with the closed box cover. The portable SF6 gas density measuring device is matched with a rotational unlock structure through an electromagnetic device to allow the device to automatically perform electromagnetic suction locking of the device close over when the device is in use and is covered so as to better avoid the risk of fall-off of a detection device stored in thedevice caused by user lock leakage and facilitate use; the device is provided with a negative pressure suction device cooperated with the electromagnetic device to allow the device to drive the negative pressure device to perform closing suction of the device when the device is in electromagnetic suction to allow the device to perform dual-closing locking and allow the negative pressure suction not to be failed when the electromagnetic locking is failed so as to further ensure the safety of the device.
Description
technical field [0001] The invention is a portable SF6 gas density measuring device with a cover that can be conveniently locked, belonging to the field of portable SF6 gas density measuring devices. Background technique [0002] Because SF6 is a colorless, odorless, non-toxic, non-flammable inert gas. Due to the chemical properties of this gas is stable. And it has excellent arc extinguishing and insulation properties, so it is often used in a wide range of power equipment. In order to measure the SF6 gas density of the equipment during use, a more portable portable SF6 gas density measurement device was invented. [0003] When the traditional portable SF6 gas density measuring equipment is in use, 1. When storing the equipment, it needs to be locked manually. It is easy to fail to ensure that the equipment is in a locked state due to locking errors, which will easily cause the equipment to fall when it is carried. , causing inconvenience; 2. The locking method of the dev...
