This utility model relates to the field of charging pile technology, specifically to a charging gun anti-detachment structure for charging piles. It includes a base, a charging body mounted on one side of the base, and an anti-detachment component installed between the charging body and the charging gun. The anti-detachment component prevents the charging gun from falling off. Compared to existing technologies, this application, by setting the anti-detachment component, allows for manual pressing of the trigger handle after the charging gun is fully inserted, aligning the latch with the lock hole of the locking block. Upon release, a pressure spring pushes the latch to automatically engage in the lock hole, completing the lock. At this time, the arc-shaped support surface of the support block continuously abuts against the charging gun, providing auxiliary fixation. Furthermore, under external force, the weight of the charging gun is converted into a radial locking force of the latch, achieving self-reinforcing anti-detachment. To unlock, both sides must be pressed simultaneously. The trigger rod retracts the latch and the support block resets, allowing the charging gun to be safely removed.

The utility model relates to a kind of helical gear pump with multiple-tooth number asymmetric same modulus involute tooth profile, belong to helical gear pump technical field. Including back cover, positioning pin, floating sleeve, driving helical gear, driven helical gear, high-pressure sealing assembly, sealing ring, front cover, rotating lip skeleton oil seal, hole with clasp spring, bolt and pump body;Driving helical gear and driven helical gear are multiple-tooth number asymmetric same modulus involute tooth profile helical gear.The driving helical gear and driven helical gear in the utility model adopt multiple-tooth number asymmetric same modulus involute tooth profile, while increasing tooth thickness, leave out rotation space for addendum, ensure the strength and the stability of operation of gear, under the same addendum circle diameter, compared with standard helical gear, increase 4-6 tooth number, reduce flow pulsation, reduce noise.

This utility model relates to a drill string processing system for oil drilling rigs, including a two-tier manipulator, a drill platform manipulator, a powered slip device, a steel drill bit, a thread cleaning device, and a traveling crane system. The two-tier manipulator is installed on the second tier of the derrick, and the traveling crane system is vertically and movably installed on the derrick. The drill platform manipulator and the steel drill bit are installed on the drill platform, allowing them to operate close to the wellhead. The powered slip device is installed at the wellhead. The thread cleaning device includes a male thread cleaning assembly and a female thread cleaning assembly. Both are installed on the drill platform; the male thread cleaning assembly cleans the male threads of the drill string located at the wellhead, and the female thread cleaning assembly cleans the female threads of the drill string located at the wellhead. Its advantages include a high degree of mechanization, significantly improved operational efficiency and safety.

A toothed chain transmission system, belonging to the field of chain drive technology, includes a toothed chain and sprockets that mesh with each other. The chain includes guide plates, toothed chain plates, pins, and rollers. Rollers are mounted on the pins. The guide plates are located on both sides of the chain, and the two ends of the pins are respectively interference-fitted with first connecting holes on the guide plates. The toothed chain plates include first toothed chain plates and second toothed chain plates. The first toothed chain plates are arranged side by side along the pin axis on two adjacent pins between adjacent guide plates. The second toothed chain plates are connected to two pins located on the inner side of the first toothed chain plates between adjacent first toothed chain plates. This invention is based on the meshing transmission principle of toothed chains and optimizes and improves the original toothed chain, thereby achieving the goals of noise reduction, load increase, and transmission efficiency improvement when used in conveying equipment, significantly improving the overall performance and reliability of the chain drive system.

The application discloses a universal joint ball pair locking mechanism and medical equipment, and relates to the field of medical equipment. The universal joint ball pair locking mechanism comprises a ball joint and a locking assembly. The ball joint comprises an inner ball head and an outer ball body which are hingedly connected with each other. The locking assembly comprises a first engaging member, a second engaging member and an unlocking driving member. The application realizes rigid locking through the engagement of the first engaging member and the second engaging member. The locking design is not affected by factors such as changes in the friction coefficient and wear, and can stably maintain the relative angle of the inner ball head and the outer ball body, thereby avoiding adverse loosening caused by friction failure and improving the stability of the locking strength. The locking assembly has two states of locking and unlocking. When unlocked, the inner ball head and the outer ball body can be universally adjusted, thereby meeting the requirement of flexible equipment to reach a target position and angle. When locked, stable support is provided through rigid engagement, and the use requirements of flexible adjustment and reliable locking are considered, so that the application is well applicable to application occasions of the stability of equipment operation.
