Abstract: The present disclosure relates to a socket with a fixing device and a charging cabinet for electric vehicles with the socket. The fixing device includes a connection mechanism, which is provided on one side of a mainbody of the socket and is adapted to releasably connect the socket to a mounting object to which the socket is to be mounted by means of a first fixing member, and a pivot mechanism, which is provided between the other side of the mainbody opposite to the connection mechanism and the mounting object, so that the socket is pivotable relative to the mounting object when released from the mounting object. Through the fixing device for the electric vehicle charging gun socket, the charging gun socket can be easily and quickly fixed on a mounting object, such as a charging cabinet, since the number of required fixing parts is reduced.

Abstract: The present application provides a compound dry powder inhalant, comprising baicalin, ambroxol hydrochloride, L-leucine and phosphate, wherein based on a mass of the compound dry powder inhalant, L-leucine accounts for 0-50%, phosphate accounts for 15-35%, and a total mass of baicalin and ambroxol hydrochloride accounts for 15-85%, and wherein a mass ratio of baicalin to ambroxol hydrochloride is 1:0.2 to 2. The compound dry powder inhalant has a Dv90?5 ?m. The drug combination of baicalin and ambroxol hydrochloride can effectively reduce inflammation and oxidative damage in lung tissue, alleviate pulmonary edema and histopathological changes, and reduce pulmonary dysfunction and pulmonary fibrosis.
