The utility model discloses a kind of rotary mechanisms, it is installed in shell, comprising: connecting rod is rotated relative to shell;Rotary shaft is equipped with driving block;Rotary member is rotated with rotary shaft cooperation, rotary member is equipped with driving rib and driving groove, one end of connecting rod is located on the rotation track of driving rib;Energy storage component is connected with rotary member;Output member is rotated relative to shell, output member is equipped with cooperation part, recess and protrusion, cooperation part is cooperated with driving block, protrusion is cooperated with driving groove, recess is located on the movement track of connecting rod;Adopt this structure, through the cooperation between rotary member, output member, connecting rod, form a linkage cooperation effect, in the case of guaranteeing main contact fast split (main spring after passing through dead point, main circuit starts to break) through the transmission of connecting rod Angle break (angle increases to 90 ° or more Angle);Connecting rod self-reset, in the process of rotating from break state to close state, connecting rod can self-reset.

The transmission assembly of the linear lifting device comprises a lead screw, a spline sleeve and a hollow hollow shaft arranged on the outer side of the lead screw in a sleeved mode, the spline sleeve is arranged on the outer side of the lead screw in a sleeved mode and rotates synchronously with the lead screw, the spline sleeve is connected with the inner wall of the hollow hollow shaft in a circumferential relative fixing and axial relative moving mode, and the spline sleeve is composed of two half sleeve bodies. The two half sleeve bodies are folded in the radial direction of the lead screw to form a spline sleeve, one of the inner wall of each half sleeve body and the peripheral side of the lead screw is provided with a positioning protrusion, the other one is provided with a positioning groove, and the positioning protrusions and the positioning grooves are matched in a radial inserting mode so that the half sleeve bodies can be axially fixed relative to the lead screw. The hollow shaft sleeves the spline housing and is used for limiting the positioning protrusions from being separated from the positioning grooves. According to the transmission assembly, the assembly process is simplified, and the integrity and the structural strength of the lead screw are guaranteed; the two half sleeve bodies can be directly folded or separated in the radial direction, and disassembly and assembly are convenient. In addition, the utility model further discloses a linear lifting device provided with the transmission assembly.

The spline sleeve comprises two half sleeve bodies and a connecting piece, the two half sleeve bodies are folded in the radial direction of the lead screw and then connected through the connecting piece to be kept in a folded state, one of the inner wall of each half sleeve body and the peripheral side of the lead screw is provided with a positioning protrusion, and the other one of the inner wall of each half sleeve body and the peripheral side of the lead screw is provided with a positioning groove. The positioning protrusions and the positioning grooves are matched in a radial inserting mode so that the half sleeve bodies can be axially fixed relative to the lead screw. In addition, the utility model further discloses a linear lifting device provided with the transmission assembly.

The present application relates to the field of medical devices, in particular to an anchoring system and a forming device thereof. In an embodiment of the present application, a limiting rod is arranged on the anchoring device, which limiting rod extends outwardly with the connecting rod as the center in a natural state, so that the blocking piece can prevent the anchoring needle from being screwed into the tissue excessively after implantation, which enables the operator to easily determine the implantation condition of the anchoring needle by operating the rotating force even in an invisible condition, and the blocking piece can press the anchoring area of the implanted device like a "washer" to provide a lateral stabilizing force, and when used for ring contraction, the blocking piece can prevent the fabric layer from being separated from the anchoring needle during the contraction process.

This utility model provides an electrical connector assembly (100), including a first component (1), a second component (2), and a third component (3). A generally flat plate (12) is provided at one end of the first component. A plurality of electrical contacts (14, 15) are provided on the surface of the plate, and a plurality of electrical contacts (22, 32) are provided on the surfaces of the second component and the third component. The plurality of electrical contacts (14, 15) provided on the surface of the plate are respectively provided on two surfaces of the plate opposite in the thickness direction. The second component and the third component abut against the two surfaces of the plate opposite in the thickness direction, such that the plurality of electrical contacts (22) on the surface of the second component respectively contact the corresponding electrical contacts (14) on one surface of the plate, and the plurality of electrical contacts (32) on the surface of the third component respectively contact the corresponding electrical contacts (15) on the other surface of the plate.

The utility model relates to the field of automobile safety products discloses a kind of reinforced connection structure and child safety seat.It includes base module and rotating module, base module is suitable for being connected with automobile seat, rotating module is located at the top of base module, and is rotatably connected with base module;Fixedly equipped with carousel fixed frame on base module, fixedly equipped with reinforcing plate on rotating module, carousel fixed frame is above reinforcing plate, carousel fixed frame is suitable for blocking the overturning of reinforcing plate relative to base module occurs.The carousel fixed frame of the utility model can play the blocking effect when reinforcing plate overturns, meanwhile bears part of overturning force, disperses overturning force, avoids that some place is relatively concentrated under stress, strengthens the stability after the connection of base module and rotating module, improves strength, so that rotating module is not prone to overturning and warping, improves the comfort of riding;The strength and stability after installation of carousel fixing piece are strengthened;The strength after cooperation of carousel fixed frame and reinforcing plate is higher.
