This invention discloses a self-service printing device, comprising a housing with an observation window and a temporary storage mechanism and a release mechanism located within the housing. The temporary storage mechanism consists of multiple parallel and inclined support units arranged sequentially along the normal direction of the observation window; the front support unit and its paper obscure the content area of ​​the rear paper, with only the side serial number area exposed. Each support unit has a support plate, a holding member, and a conductive bead. The release mechanism has electrical contacts aligned with the conductive beads. When the contact is activated, it drives the corresponding holding member to switch from holding to releasing, allowing the target paper to slide out along the support plate. This structure achieves physical obscuring of the content area and visibility of the serial number during the temporary storage stage, supporting accurate single-page release; the side serial number is permanently exposed for easy identification and position mapping; the number of contacts is small, the wiring is simple, and the paper is fed by gravity, reducing the risk of missorting and jamming, improving confidentiality, efficiency, and reliability; the structure is modular and easy to maintain.

The present invention provides an outdoor flexible display screen kit, comprising a plurality of main bodies formed by integrating display modules with hard glue, wherein the connection between adjacent main bodies is provided with a W-shaped, V-shaped or U-shaped connection structure, the connection structure and the main body are injection molded into one body, and the plurality of main bodies and the plurality of connection structures are connected on the same PCB board; by setting the W-shaped, V-shaped and U-shaped connection structures, the connection between adjacent main bodies is extended and rotated, and the plurality of main bodies, the connection structure and the connection port are injection molded into one body, compared with the traditional belt line connection assembly, the entire connection is extended, compressed and rotated, and the plurality of main bodies are injection molded into one body, all display modules use a whole PCB board, and it can be achieved that there is no need to use a belt line, thereby canceling the connector of a single small module, reducing the contact points and lowering the failure rate; and the injection molding has excellent waterproofness, low cost, high stability and simple production process.

The utility model discloses a kind of aluminum alloy chemical polishing devices, belong to aluminum alloy processing technical field, including frame, frame one side is equipped with controller, frame bottom end four corners are equipped with stand, frame is equipped with placing frame inside, placing frame is equipped with multiple baffle in straight line array distribution, frame both sides are fixedly installed with support frame, frame upper is equipped with lifting plate, lifting plate section is inverted "U" shape, two sections of lifting plate are respectively slidably placed in the same side support frame, two support frame bottom end inner wall are equipped with cylinder, two cylinder piston shaft end portion are fixedly connected with the opposite side of lifting plate, swing component is equipped between placing frame and lifting plate, lifting plate top is equipped with wind blowing component.The utility model places multiple placing areas by baffle in placing frame, it is convenient to separate and place aluminum alloy plate, it is conducive to reducing the contact point between plate, in turn, it is conducive to improving the contact area of plate and solution, in turn, it is conducive to improving the polishing effect of plate.

The application discloses a piece contact plug-in structure, which comprises a spring piece and a clamping shell, the spring piece is arranged in the clamping shell, the spring piece comprises an upper spring piece and a lower spring piece which are arranged in an up-down mode and form a plug-in slot, the upper spring piece and the lower spring piece each comprise a spring piece base body, the spring piece base body is provided with a first cantilever and a second cantilever, the second cantilever is located in a different height plane from the first cantilever, the gap between the first cantilever and the second cantilever is infinitely reduced to zero, the number of cantilevers is increased, the number of contact points is increased, the conductive performance is improved, the conductive performance is improved, the width of the spring piece base body is fully utilized, the spring piece body resistance is reduced, the current carrying capacity of the spring piece is improved, and the problem that in the prior art piece contact, the number of cantilevers and the spring piece body resistance value are fixed without increasing the width of the spring piece base body, the conductive performance and the current carrying capacity are fixed, and the conductive performance and the current carrying capacity cannot be improved is solved.

The utility model relates to a battery shell electroplating processing clamp which comprises a U-shaped support, a sliding hole and a mounting hole are formed in the two ends of the U-shaped support respectively, and a first clamping rod is mounted in the sliding hole in a sliding mode. The utility model relates to the technical field of battery shell electroplating. According to the electroplating machining clamp for the battery shell, by pressing the U-shaped support, the ejector rod makes contact with the bottom wall of the electroplating pool, the ejector rod jacks up the battery shell, then the contact point of a battery is lowered, meanwhile, the fixing cylinder moves downwards and rotates at the same time so as to drive the battery shell to rotate, and then after the battery shell rotates, the battery shell is fixed to the electroplating pool. And the original contact position of the spherical bulge and the telescopic head is staggered with the spherical bulge, so that any position of the battery shell can be in full contact with electroplating liquid, the effect that a contact point is difficult to uniformly coat a film can be effectively avoided, and the electroplating uniformity can be fully improved.
