Through the arrangement of the frame line compacting mechanism, the multi-stage electric push rod drives the connecting block, the I-shaped sliding groove column and the I-shaped sliding column to compact the bottom frame of the carton, so that the situation that the bottom frame of the carton tilts in the carton bottom sealing process of a carton sealing structure between the two conveying belts is avoided; and the adhesive tape can be better adhered to the frame of the carton, so that the situation that the adhesive tape is loosened due to infirm adhesion is reduced.

The utility model relates to the technical field of connectors, in particular to a waterproof Type-C connector female seat which comprises a metal shell, a tongue plate is connected to the rear surface of the metal shell in an embedded mode, a terminal set is connected to the outer surface of the tongue plate in an embedded mode, and a waterproof mechanism is connected to the outer surface of the metal shell in an embedded mode. The waterproof mechanism comprises a rubber cushion plate, a waterproof ring and a limiting strip, the rubber cushion plate is placed on the upper surface of the metal shell, the waterproof mechanism is integrally formed through the injection molding technology, the installation mechanism exerts downward pressure on the waterproof mechanism, and the limiting strip is located at the gap position between the front limiting bent part and the first installation foot. Through cooperation of the rubber base plate and the mounting shell, the waterproof mechanism can be prevented from falling off, the rubber base plate blocks the joint position of the upper surface of the metal shell and compensates for the extrusion sheet, and the waterproof ring blocks the gap between the metal shell and the external equipment, so that falling off is avoided, and the later waterproof capacity is improved.

The utility model discloses a kind of optical communication module of improving stable reliability, comprising: upper shell, optical communication module main body, lower shell, pull belt, rivet and U-shaped rivet pressing piece;Upper shell is provided with foolproof limiting post and upper through-hole inside;Optical communication module main body includes PCBA and cable, the side of PCBA is provided with limiting card slot, optical communication module main body is placed and positioned in upper cavity, foolproof limiting post is clamped into corresponding card slot, to prevent PCBA from moving back and forth;Lower shell is provided with lower through-hole;Pull belt includes pull ring part and two left and right interval setting unlocking arms, reset spring is arranged between pull belt and lower shell;Lower shell is spliced downward in upper shell, and the upper end and lower end of PCBA are limited by upper shell and lower shell respectively;Rivet passes through upper through-hole and lower through-hole, to connect and position upper shell and lower shell;U-shaped rivet pressing piece clamps upper shell and lower shell, and its two end rivet pressing is bent. In this way, it is easy to assemble and stably position, especially PCBA is reliably positioned, to prevent shaking.

This application belongs to the field of fiber drawing machine technology and discloses a reciprocating multi-station multi-variety glass fiber ply yarn drawing machine, including a frame and a base plate. The base plate has two mounting holes, one above the other, each containing a turntable. Two sets of main shaft impeller mechanisms are slidably mounted on the turntables along the length of the frame. A tilting mechanism and a reciprocating mechanism are respectively installed inside the frame corresponding to the two turntables. The tilting mechanism drives the two sets of main shaft impeller mechanisms on the turntables to switch between working and standby positions. The reciprocating mechanism drives the main shaft impeller mechanism in the working position to slide along the length of the frame. A forced yarn splitting mechanism, a yarn blocking mechanism, a yarn arrangement mechanism, a water pipe mechanism, and an automatic yarn unloading mechanism are respectively installed on the frame corresponding to the two turntables. An automatic yarn feeding mechanism is slidably installed at the bottom of the frame. This application forms a dual-drawing station, which can independently carry out drawing operations without interference. It can be adapted to high-flow spindles or multiple spindles to increase yarn production and reduce the floor space of the production line.

This utility model discloses an integrated injection molding device for a corner window assembly, comprising: an injection molding machine, a front and rear positioning mechanism disposed on the front of the injection molding machine, and a clamping mechanism, the clamping mechanism including a cylinder, the cylinder being fixedly connected to both sides of the injection molding machine, a lifting block being fixedly connected to the top of the cylinder, and a drive shaft being fixedly connected to the front of the lifting block. This utility model, by setting the clamping mechanism, can position the sides and top of the injection mold, preventing the injection mold from tilting or moving left and right. By setting the front and rear positioning mechanism, the injection mold can be positioned front and back, preventing the injection mold from moving back and forth. During injection molding, the mold will not shake, avoiding separation of the mold from the discharge port, facilitating user operation, and ensuring normal use.
