The utility model provides a manual point gum machine for display screen production relates to display screen production equipment technical field, include: point gum subassembly, point gum subassembly constitutes by point gum pipe, threaded rod and pump head, the pump head sliding connection is in the point gum pipe, threaded rod sets up at the top of pump head, the embedded installation of point gum pipe is equipped with visual glass, drive assembly constitutes by inside, outside drive disc, the layout is exquisite, the effect is remarkable, the first tooth groove of inside drive disc outside and the inside ring of outside drive disc mesh, realizes the collaborative operation of inside and outside disc, power transmission is efficient and stable, the second tooth groove of outside drive disc outside and the drive gear on fixed link mesh, supports through fixed link, drive gear can accurate drive outside drive disc rotation, this structure makes the drive flexible controllable of point gum pipe, can accurate regulation rotating speed and torque according to the operation demand, guarantees the smooth, accurate of point gum operation, has greatly promoted the working performance and product quality of point gum equipment.

A toothed chain with a sealing ring sleeve, belonging to the field of chain technology, includes a toothed chain body with a sealing ring sleeve. The toothed chain body includes: an outer chain plate, an inner chain plate, a guide plate, a pin, a sleeve, and a sealing ring. The guide plate has a rectangular frame structure with a downward-protruding arc structure one at the bottom and outward-protruding arc structures two at both ends of the top. The radius of the arc structure two is R″ = R5.5-R7.5. This new invention solves the technical problems of chain slippage, tooth skipping, and excessive vibration of the chain at high speed in some models of Zhenming chains under extreme working conditions and extreme violent driving conditions. By optimizing the guide plate design and reducing the weight of the chain, the overall stability of the chain is improved, ensuring efficient transmission under various complex road conditions.

This invention relates to an air filter, an aero-engine, and an aircraft, belonging to the field of aerospace technology. It solves the problem that existing air filters, located externally to the cabin, have weak drainage capabilities in rain and snow, limiting aircraft usability. The invention includes a support and drive unit and multiple guide plates; wherein the support and drive unit includes a support member; multiple guide plates are circumferentially arranged on the support member, and the guide plates are rotatable relative to the central axis of the support member to displace rainwater. This invention improves the drainage performance of the air filter in rain and snow.
