The invention provides a battery box with a waterproof structure. The battery box comprises a battery box upper cover and a battery box lower box body connected through a fastening part, wherein a sealing strip is arranged between the battery box upper cover and the battery box lower box body; a stepped structure including two times of downward bending and one time of outward turning is arranged on the edge of the battery box upper cover to form a first upper cover lower bending part, an upper outer turning edge and a second upper cover lower bending part connected in sequence; the edge of the battery box lower box body is integrally bent upwards, then pressed downwards completely, and then turned outwards to form a lower box inner turning edge, a lower box upper bending part, a lower box body top complete-pressing edge and a lower box outer turning edge connected in sequence. According to the battery box, the sealing strip is mounted in a sealed space formed by the bending turning edges of the battery box upper cover and the battery box lower box body, so that the sealing strip can be prevented from extending towards two sides, and the compression amount of the sealing strip can be ensured; and the adjustment of the compression amount of the sealing strip can be realized by controlling the distance from the bottom of the second upper cover lower bending part to the inner turning edge of the box body.

A liquid ejecting head includes a second flow-path-member comprising a second flow-path in communication with first and third flow-paths provided in first and second flow-path-members, the second flow-path-member stacked with the third flow-path-members in a stacking direction. A boundary between the first and second flow-path is tightly sealed by a first sealing-member. A boundary between the second and third flow-path is tightly sealed by a second sealing-member. The second flow-path-member includes a first substrate for positioning itself to the third flow-path-member in first and second directions intersecting with the stacking direction, and a second substrate for positioning itself to the third flow-path-member in the stacking direction. The first substrate is pressed against in the first and second directions by one of the first and second sealing-member. The second substrate is pressed against in the stacking direction by another one of the first and second sealing-member.

The invention provides a pressure-adjustable floating abrasive belt grinding device with a feedback. The upper part of a supporting plate is provided with a driving wheel and a cylinder; the piston rod of the cylinder faces downwards vertically and is connected with a fine-adjustment sliding plate by a guide column; the bottom end of the fine-adjustment sliding plate is provided with a contact wheel which is connected with the driving wheel by an abrasive belt which coils an idler wheel; a guide column is movably sheathed by a spring which is in a normal-compression state; the position of theupper end of the spring is limited by a nut which is fixed on a guide column; the position of the lower end of the spring is limited by a baffle which is fixed on the supporting plate; furthermore, the guide column passes through the baffle. The grinding device eliminates the effects of the self-gravity of the grinding head during the grinding process by an added spring mechanism, controls the grinding pressure of the contact wheel within an allowable error range, keeps constant pressure, thus effectively improving the processing precision of complex curved surfaces such as steam engine vanes;furthermore, the grinding device ensures the quality of the profile of the workpiece, and has the advantages of smart concept, simple structure, easy execution, low reconstruction cost, good consistency of product, wide applicable range, and the like.

The invention discloses a gluing device for the production of green bamboo-wood composite flooring and a process thereof, which belongs to the technical field of gluing the bamboo-wood composite flooring, and comprises a bottom plate. Two slide rails arranged parallel to each other are installed on the upper surface of the bottom plate. And the upper surface of the bottom plate is provided with two storage boards, the storage boards are slidably installed on the slide rail, the inside of the slot is provided with a clamping assembly for clamping the workpiece, and the front and rear sides of the bottom board are equipped with Hollow square column 1, the top of two described hollow square columns 1 is installed with the same hollow square column 2; By setting the slide rail, the sliding installation of the storage board on the bottom plate is realized, thus making it convenient for people to adjust the storage board and fix it on the The position of the workpiece on it enables people to load the workpiece on one of the storage boards while gluing the other storage board, which realizes the full use of time and is conducive to improving the efficiency of the entire gluing device. work efficiency.
