Technical fields:

[0001] This utility model belongs to the field of rail transit equipment technology, specifically relating to a quick locking and unlocking device that can quickly fasten and separate two locking components. Background technology:

[0002] Existing locking devices for through passageways are complex in structure, require specialized opening tools, are time-consuming and labor-intensive, and are inconvenient to use. For example, Chinese Patent 202411934570.8 discloses a locking assembly including a locking hook, a locking plate that slides relative to the locking hook, and a rotating block installed at the bottom of the locking plate. The locking plate has a locking hole into which the locking hook can be inserted. The rotating block has a rotating groove that is spirally formed. The bottom of the locking plate abuts against the bottom of the rotating groove. A driving component is also installed on the rotating block. Manipulating the driving component can drive the rotating block to rotate relative to the locking plate. The driving component is a protrusion on the rotating block, which has a multi-faceted prism structure. The protrusion and the rotating groove are located on opposite sides of the rotating block. The driving component is also a lever block on the rotating block, which protrudes radially. The spiral center of the rotating groove is the rotation center of the rotating block. Chinese Patent 202121632171.8 discloses a side guard plate locking system, including a side guard plate, a locking hook, a frame, a locking plate, an arc-shaped spring plate, and a stop bar. The locking hook is fixed to the side of the side guard plate near the vehicle body. The frame's internal cavity has a groove along its height direction, and the lower part of the locking plate is placed in the groove and can slide along it. The locking plate has a locking opening that matches the locking hook, and a handle is provided at the top of the locking plate. The arc-shaped spring plate is located on the non-handle side of the locking plate, with its arc-shaped arch facing the locking plate surface, and its arc length along the height direction of the locking plate. One end of the arc-shaped spring plate is fixed, and the other end is a movable free end. The frame's internal cavity has a fixed... The stop bar is positioned horizontally between the end of the arc-shaped spring plate and the arched part. When the locking plate slides down, the outer edge of the stop bar engages with the arc-shaped spring plate. The stop bar is cylindrical, with its side wall in contact with the arc-shaped spring plate. Both ends of the stop bar are fixedly connected to the inner wall of the frame. The top of the arc-shaped spring plate is fixed, while the bottom is a free, movable end. The arc-shaped spring plate is fixed to the locking plate with screws. The frame is made of grooved aluminum profile. The upper and lower parts of the locking plate have two locking holes, and the upper and lower parts of the side guard plate also have corresponding locking hooks. The locking plate is made of steel, and its top handle is a bend formed by the locking plate itself.Chinese Patent 202022543858.6 discloses a side guard plate locking system, including a side guard plate, a locking hook, a frame, a locking plate, a positioning ball screw, and a base. The locking hook is fixed to the side of the side guard plate near the vehicle body. The frame has a groove along its height direction, and the locking plate is inserted into the groove from its lower end and can slide along the groove. The locking plate and the frame have locking holes that match the locking hook. The top of the locking plate has a handle. A fixed base is provided on one side of the locking plate located in the groove. The positioning ball screw is installed on the base and located between the base and the locking plate. The locking plate located in the groove has a movable groove and a positioning groove along its height direction, with the movable groove located above the positioning groove. It also includes a spring and a guide. The system includes a guide post and a pressure plate. The guide post is fixed to the bottom of the base, and a spring is fitted onto the guide post. A pressure plate is fixed to the locking plate, and the spring is located between the fixed base and the pressure plate. The upper part of the locking plate has an elastic pin that can be locked onto the upper edge of the frame. The movable groove is oblong, and the positioning groove is circular. The upper and lower parts of the locking plate have two locking holes, and the upper and lower parts of the side guard plate also have a corresponding locking hook. The height difference between the locking plate in the suspended state and the locked state is 30mm. The base is fixedly connected to the frame. Chinese Patent 201922182102.0 discloses a novel side guard plate locking mechanism, comprising: a mounting base pre-installed on the end face of a train, on which a column for connecting the main body of the side guard plate is mounted; the mounting base includes a seat plate, the top of which is locked to the top of the column by a locking structure; the bottom of which is locked to the bottom of the column by a hook-lock structure; a locking interface is provided at the top of the column; the locking structure includes four corner locking shafts; the four corner locking shafts are horizontally positioned at the top of the locking interface, and rotating tongues are fitted on the four corner locking shafts, with a crank rotatably connected to the bottom of the rotating tongues by a pin; the locking structure also includes a pin, on which a compression spring is fitted, and a compression spring stop is installed on the upper part of the pin. The crank base is rotatably connected to the latch via a pin. The locking structure also includes a pin shaft and a pin sleeve. An installation interface is provided on the base plate. The pin shaft is fixed within the installation interface and fitted into the pin sleeve, which abuts against the locking interface. The bottom of the latch is simultaneously inserted into both the pin sleeve and the pin shaft. A base is provided at the bottom of the base plate, and a hook is provided at the bottom of the column. The hook locks onto the base, and the base and hook form a hook-lock structure. A decorative strip is installed on the column, and both ends of the column are sealed. The pin shaft is welded to the installation interface. Triangular indicator marks are provided on the four corner locking shafts for observing whether the latch is properly inserted or removed. The base is welded to the base plate, and the column is made of extruded aluminum profile. Therefore, it is necessary to develop and design a quick locking and unlocking device that can tighten or loosen the two locking components by directly operating the lock cylinder without prior disassembly. Summary of the Invention:

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and to develop and design a fast locking and unlocking device that is simple in structure, reliable in locking, and easy to operate.

[0004] To achieve the above objectives, the main structure of the quick locking and unlocking device of this utility model includes a lock cover and a lock cylinder installed inside it; the lock cover is installed on the locking component by a locking nut, the lock cylinder is installed inside the lock cover by a rubber ring, a locking washer is provided between the locking nut and the locking component, and the inner end face of the lock cover is a bevel.

[0005] Compared with the prior art, this utility model includes a control element, a lock cylinder, which can be accessed from the side facing the user. During the separation process, the lock cylinder can be operated using a tool including a wrench, without prior disassembly steps. Once the lock cylinder is rotated, the tightening or separation is completed immediately without further assembly steps. The end face of the lock cylinder is flush with the end face of the lock cover, serving as a safety mark indicating that the lock is in place. Its structure is simple. Installation and disassembly can be achieved by rotating the lock cylinder to screw it into and out of the lock seat provided on another locking component. The connection between the locking components can be established or disconnected very quickly simply by driving the lock cylinder, without the need for complex or special tools.
