A self-unlocking, self-buffering, rotary-locking multi-section drag-reducing rod, relating to the field of spacecraft structures, includes an outer shell, an intermediate shell assembly, an inner shell, a gas generator, a self-unlocking component, and a chassis. The intermediate shell assembly is located inside the outer shell, and the inner shell is located inside the intermediate shell assembly. The intermediate shell assembly includes multiple shells nested sequentially. Any two adjacent shells form an outer shell and an inner shell. The top of the inner wall of the outer shell has a raised inner ring segment, and the inner ring segment has multiple rotating U-grooves arranged circumferentially. The outer wall of the inner shell is provided with cylindrical guide pins, which mate with the rotating U-grooves one by one. The chassis is fixedly connected to the bottom of the outer shell. The gas generator is connected to the middle of the chassis and extends into the inner shell. The self-unlocking component is located at the outlet of the gas generator so that the outlet of the gas generator opens after the self-unlocking component is unlocked. This invention solves the problems of large unlocking impact, large positioning impact, and excessive gap in the locking structure of existing multi-section deployable locking drag-reducing rod structures.

The utility model discloses a kind of mute door groups in the technical field of acoustics engineering, including door frame, the door frame inside is connected with door panel by hinged installation, first lock tongue accommodating slot is opened in the right edge of the door panel inside, the position of the door frame corresponding to door panel first lock tongue accommodating slot is equipped with second lock tongue accommodating slot in its and the inside surface of door panel bonding;The door panel inside is equipped with a transmission groove with specific bending line, by setting transmission groove, transmission ball and other structures between door frame and door panel and reasonable layout, reach accurate stable locking purpose.Compared with traditional mechanical lock, avoid rebound sound, do not destroy quiet atmosphere, compared with magnetic attraction lock, not affected by environmental humidity and frequent opening and closing, not demagnetization, guarantee door lock suction force and security performance.When door panel is closed, trigger slider drives lock tongue to insert into slot through transmission ball, reset spring helps reset, make locking reliable, convenient operation, improve door group safety, durability and practicality.

The utility model belongs to the technical field of electric bicycle accessories, and discloses a magnetic power supply connecting assembly capable of being quickly plugged and unplugged, which comprises a plug main body and a socket main body, the plug main body consists of a plug boss and a plug handle, a plug raised line is arranged between the plug boss and the plug handle, and the plug raised line is connected with the socket main body. Two discharging jacks are formed in the middle area of the top face of the plug boss, two first signal jacks and two second signal jacks are formed in the upper sides and the lower sides of the two discharging jacks respectively, a waterproof rubber ring is arranged on the side wall of the plug boss, and a first annular magnet is embedded in the plug boss. According to the magnetic attraction power supply connecting assembly, simple operation and reliable locking functions are realized by utilizing the characteristic of magnetic attraction, and the operation experience of a user is greatly optimized.

The utility model relates to a seat-free handle and a lockset, which belong to the technical field of door locks, and comprise a rotating wheel and a rotating wheel seat, one end of the rotating wheel is provided with a clamping part in a protruding manner, and the peripheral side of the clamping part is provided with a plurality of clamping holes and unlocking holes at intervals; a first assembling groove is concavely formed in one end of the rotating wheel seat, a plurality of assembling holes are formed in the side wall of the first assembling groove, elastic pieces and clamping balls are arranged in the assembling holes, one end of each elastic piece acts on the bottom of the corresponding assembling hole, and the other opposite end of each elastic piece acts on the corresponding clamping ball; when the clamping bead enters the clamping hole under the elastic action of the elastic piece, the rotating wheel base and the rotating wheel are in a clamping state, at the moment, the rotating wheel can be rotated, the side wall of the clamping part extrudes the side, facing the assembly hole, of the clamping bead, the clamping bead leaves the clamping hole and enters the unlocking hole to achieve an unlocking state, and the depth of the clamping hole is larger than that of the unlocking hole.

This utility model relates to the field of construction guardrail technology and discloses a construction platform guardrail device integrating a protective net, comprising: five sets of guardrails fixedly installed above the construction platform; a gate installed on one side of one set of guardrails via a connecting component; a protective plate installed on the guardrails and gate via an installation component; a protective component arranged on the protective plate; a gate stop mounting block fixedly installed on the gate; and a gate stop component arranged on one side of the gate stop mounting block. The combination of the protective plate and the protective net forms a multiple protective barrier to prevent personnel and objects from falling; reinforcing bars enhance impact resistance; warning lights provide safety markings in low-light environments; and toe boards prevent tools and materials from slipping off the edges; the cooperation of the convex and concave semicircular rings and connecting shafts ensures a stable connection between the gate and the guardrails and facilitates opening; the semicircular ring structure of the installation component allows for quick fixing of the protective plate; and the gate stop component provides a locking function, balancing construction convenience and safety, and improving on-site work efficiency.

An externally locking connector structure includes a male connector and a female connector. The male connector includes a male plug, an outer spring-loaded latch, and an internal male pin. The female connector includes a female socket, an outer snap-fit, and an internal female pin. The male plug and female socket, male pin and female pin, and spring-loaded latch and snap-fit ​​are all correspondingly matched. The male plug has a slot 1, in which the male pin is located. The female socket has a slot 2 and an insulating post, with the female pin embedded in the end face of the insulating post. The male plug and slot 2, and the insulating post and slot 1 are dimensionally matched. The inner wall of slot 1 has guide ribs and anti-misalignment ribs, and the outer wall of the insulating post has corresponding anti-misalignment grooves. The outer wall of the male plug has a sealing ring, a spring-loaded latch, and a limiting protrusion. The outer wall of the female socket has a guide groove and a snap-fit ​​with a three-gradient ramp. This structure achieves external locking, accurate and smooth mating, anti-misalignment, IPX7 waterproof rating, convenient locking and unlocking, assembly feel feedback, and overvoltage protection, improving operation feel and reliability.
