A rotational damper (2) having a damper housing (4) which surrounds an electromagnetic damper motor and is fastened via a fastening part to a first mass, and having a coupling lever (6) which is mounted pivotably with respect to the damper housing (4) and is connected to a second mass, a strain wave gear mechanism (10) for vibration damping which has a rigid unit (12) which has an internal toothing system and is connected to the damper housing (4), and a flexible unit (14) which has an external toothing system and is connected to the fastening part. The two units of the strain wave gear mechanism (10) are coupled to one another in a positively locking manner via the toothing systems in order to transmit and / or convert a rotational movement. A wave generator is mounted rotatably in the flexible unit (14), upon the rotation of which wave generator the flexible unit is deformed. A wrap spring (30) is arranged in an operative connection with the flexible unit (14), which wrap spring (30) is connected on one side to the coupling lever (6) and on the other side to the fastening part, in each case fixedly so as to rotate with it, wherein the wrap spring (30) is designed in order to lock the strain wave gear mechanism (10) by way of deformation of the flexible unit (14) in the case of predefined pivoting of the coupling lever (6) with respect to the fastening part.

The invention relates to a latched lock enhancing design for night lock that belongs to mechanical lock field in daily life. Uncertain location billiards group is set for thief. And reversing locking structure is set in the lock. When normally lock or unlock, the lock degree of the night lock is zero. When using the method beside key, the billiards group is easy to take action to reversing latch the lock. Thus, the difficulty to unlatch the lock would be increased.

A leather button structure for a package or a decoration includes a package or decoration body, and a piercing ring and a tongue fixed on the body, which is characterized in that the front view of the piercing ring is V-shaped and the front view of the utmost front end of the tongue is also V-shaped; the V-shaped inner included angle of the piercing ring is larger than that of the tongue and is an obtuse angle; the longitudinal section shape of the piercing ring is a curved surface shape with the middle high and two sides low, the middle part is a straight line with two ends respectively smoothly and transitionally connected to a segment of curve, the other ends of the two curves are connected to the package or the decoration, the piercing ring is shaped by at least two sheet materials, and the side faces of the adjacent sheet materials are spliced into a whole through heat bonding. The leather button structure of the invention has strong locking capacity. The V-shaped leather piercing button makes the package or the decoration more beautiful, especially the V-shaped tongue and the piercing ring made of two sheet materials with different color are brighter.

The invention belongs to the technical field of semiconductor devices, and in particular relates to a preparation method of a lead frame with rough side walls. In the present invention, one-side brown oxidation is performed on the upper surface of the lead frame, and then the half-etched area and the side wall are subjected to super-roughening treatment after electroplating and etching, and the side wall and the half-etched area are formed by controlling the ultra-roughening process conditions. The rough surface with good roughness increases the bonding force between the lead frame and the contact area of ​​the molding resin, while the lower surface of the lead frame is not roughened, and only a smooth pre-plating layer is formed on the exposed pad area, which reduces surface roughness At the same time, the bottom surface is not easy to adhere to the flash generated during the plastic sealing process, which reduces the difficulty of cleaning, facilitates the simplification of the process, and saves the cost of roughening and electroplating. The side wall of the lead frame of the invention has good roughness, improves the airtightness and reliability of the integrated circuit packaging body, and reduces defects such as delamination and cracking.

The invention discloses an anchor rod jacking mechanism which comprises a fixing mechanism, a supporting mechanism, a sliding block and a drill box mechanism. The fixing mechanism comprises a base, a stand plate and a connecting seat. Protrusions for fixing guide blocks are arranged on the stand plate. The supporting mechanism and the sliding block are in sliding connection with the opposite side faces of the stand plate through the guide blocks respectively. One end of the supporting mechanism and one end of the slide block are connected with base through telescopic oil cylinders. The drill box mechanism comprises a bottom frame and two independent drill box sliding seats. The bottom frame is connected with the base, and the drill box sliding seats can horizontally move along the bottom frame. When the drill box sliding seats move to the sliding block, the drill box sliding seats can be connected with the other guide rail face of the sliding block and slide along the sliding block. The invention further discloses an anchor rod jacking drilling carriage with a drilling machine. The anchor rod jacking drilling carriage comprises a four-wall anchor rod jacking drilling carriage body and a six-arm anchor rod jacking drilling carriage body. The drilling machine in the anchor rod jacking drilling carriage can work at the same time. Fast supporting operation on a top plate can be achieved, the structure is compact, and multiple functions are achieved. The anchor rod jacking mechanism and the anchor rod jacking drilling carriage operate in cooperation with heading equipment to complete the supporting and transferring function synchronously, operating personnel are greatly reduced, the labor intensity is lowered, and the supporting efficiency and safety are improved.
