The invention discloses a sealing method for a USB (universal serial bus) interface; the USB interface is sealed through a USB intelligent key; the invention also discloses the USB intelligent key, which comprises an interface protection cover used for sealing the USB interface of the terminal; a cover plate pin is arranged in the interface protection cover; the cover plate pin can correspondingly conduct with a USB pin of the terminal and is capable of transmitting signals under the state that the USB interface is sealed by the interface protection cover; one end, which is far away from the cover plate pin, of the interface protection cover is provided with a cover plate key used for triggering a specified signal. The scheme also discloses a terminal with the USB intelligent key. According to scheme, the interface protection cover is arranged at the USB interface position of the terminal, and the interface protection cover is provided with the cover plate pin and the cover plate key, wherein the cover plate pin can conduct with the terminal, and the cover plate key is capable of triggering the signals, not only is the sealing protection on the USB interface of the terminal realized to effectively prevent liquid and foreign matter from entering the USB interface, but also a control key is additionally arranged on the terminal, so the interestingness and the convenience are enhanced.

The invention discloses an inspection well lid facilitating theft prevention. The inspection well lid comprises a well seat and a well lid body, clamping grooves are formed in the inner wall of the well seat in a concave mode, an accommodating cavity is horizontally formed in the well lid body, a sleeve with the upper end being not provided with a sealing opening is welded to the upper end of the accommodating cavity, a vertical rod is vertically welded into the middle end of the accommodating cavity, a rotating disc is rotationally arranged at the middle end of the vertical rod in a sleeving mode, three connecting grooves are formed in the rotating disc in circumferential array and concave modes, and a supporting spring is rotationally arranged at the top end of the vertical rod. According to the inspection well lid, a suspension cover is arranged in a suspended mode, so that the suspension cover and an opening and closing structure for directly opening the well lid are mounted in a differentiated mode, the purpose of opening the well lid is achieved through rotation of the suspension cover and the rotating disc, a well lid opening switch is arranged in a hidden mode advantageously, thus the opening difficulty is improved, and the theft preventing function is effectively achieved; and by arranging the sleeve, the suspension cover is protected through a threaded cover in threaded connection with the sleeve, so that repeated extrusion of ground surface external force to the suspension cover is avoided, and the service life of the well lid is prolonged advantageously.

The invention relates to short-distance transportation equipment used in the magnesium sulfate processing process, wherein the multi-layer plate frame and the supporting column are correspondingly arranged on the vehicle body, and the containing boxes are sequentially arranged on the multi-layer plate frame and rotationally connected with the supporting column. The containing boxes are matched with upper plates and lower plates in the multi-layer plate frame to form a sealed box body, and a driving mechanism which can vertically move and is used for sequentially driving the multiple containingboxes to horizontally rotate to achieve opening or closing of the containing boxes is arranged on the vehicle body. The upper plate and the lower plate in the multi-layer plate frame are matched withthe placing box to form a sealed box body, so that magnesium sulfate in the placing box is sealed and protected; and secondly, the first incomplete gear and the second incomplete gear are correspondingly engaged with the rotating gear and the lifting gear correspondingly and rotate in a front-and-back staggered engagement mode, so that the multiple containing boxes on the multi-layer plate frameare sequentially rotated up and down to be opened or closed, quick loading and unloading of magnesium sulfate are achieved, and the situation of magnesium sulfate leakage is avoided.

The invention discloses an interconnection and package method on the basis of TSV (through silicon via) chips. By the aid of silicon interposers, interconnection of multi-layer laminated chips with narrow salient points and narrow spacing is changed into interconnection with large salient points and large spacing, and accordingly, subsequent installation process is achieved. By means of padding-bottom among the chips, between the chips and the interposers, and between the interposers and a substrate, multi-layer chip structure and the substrate structure are fixed onto the substrate. By means of package, seal protection of the TSV unpacked chips is realized and reliability of devices is improved.
