A cord hook for fastening a jump mat to a trampoline frame includes a holding section for holding a first and a second loop end section of the cord loop and a fastening section for fastening the flexible band element, wherein a main tension vector (V) is defined by tension at the band element. The hook has a transition section connecting the holding section and the fastening section and is designed in such a way that a straight line (g) through the main tension vector (V) divides the holding space into a first partial space and a second partial space in such a way that, when the cord hook is used as intended, the first loop end section lies in the first partial space and the second loop end section lies in the second partial space. Also disclosed are a trampoline and a method for fastening the jump mat.

The invention discloses a dismounting device. The dismounting device comprises a base and a top beam, wherein a guide mechanism is arranged between the base and the top beam; a first power device is hinged between the base and the top beam, which are located on the two sides of the guide mechanism; the base is further provided with a slide seat, which is driven by a second power device, in a sliding manner; and the slide seat is internally and vertically provided with at least two grasping mechanisms, which are driven by a third power device, in a sliding manner. With the adoption of the dismounting device disclosed by the invention, the labor intensity of workers is greatly alleviated, and the working efficiency and the working safety are improved; and meanwhile, a top plate is supported stably and reliably, a danger that the top plate cap falls off is avoided, and thus the working safety is further improved.

The invention relates to a valve (1) for controlling liquids, comprising a valve housing (10) having an actuator chamber (11) and a laterally arranged inlet hole (13) that is connected to a high pressure inlet (12), wherein the actuator chamber (11) has an actuator (30) with a plunger (31) and a round end (32), wherein the actuator chamber (11) has a taper gasket that is configured by means of a conical surface (14) on the end of the actuator chamber (11) and a matching annular sealing surface (33) on the round end (32) of the actuator, wherein a cable outlet (17) can be sealed off with the taper gasket. The actuator chamber (11) has at least another inlet hole (13). This makes it possible to achieve a more even power distribution to the actuator (30).

The invention relates to a damper (1) for furniture, which comprises a housing (2) in which a piston (4) connected with a piston rod (3) is received in a mobile manner. When the piston (4) is displaced in the housing (2), a fluid flows through a flow channel (20) arranged on or in the piston (4). Meanwhile, different damping forces are generated when the piston (4) is displaced in different directions. Thus, parts of the cross section of the flow channel (20) can be modified by displacing the piston (4) relative to a plate (6). The plate and / or the piston is provided with radially extending grooves for forming at least one part of the flow channel (20). One side of the housing is provided with a movable balance piston. The balance piston is hermetically guided on the housing and the piston rod. The balance piston is provided with a sealing member. The sealing member abuts against the housing through an outer sealing lip and abuts against the piston rod through an inner sealing lip.

The invention provides a dual-guiding work roll bending and balancing device of a plate and strip rolling mill. The dual-guiding work roll bending and balancing device of the plate and strip rolling mill comprises a bending and balancing cylinder. A cylinder block of the bending and balancing cylinder is fixedly arranged on the inner side wall of a mill housing. An upper piston rod is arranged on the top of the cylinder block in sealing, penetrating and sliding manners. A lower piston rod is arranged at the bottom of the cylinder block in sealing, penetrating and sliding manners. The free end of the upper piston rod is connected with an upper guide cover, wherein the upper guide cover abuts against the upper portion of the outer wall of the cylinder block in a sliding manner and can move up and down along the mill housing. The top of the upper guide cover abuts against an upper work roll assembly bearing seat. The free end of the lower piston rod is connected with a lower guide cover, wherein the lower guide cover abuts against the lower portion of the outer wall of the cylinder block and can move up and down along the mill housing. The dual-guiding work roll bending and balancing device of the plate and strip rolling mill overcomes the defects that in the prior art, a guide ring and a seal ring are prone to damage, oil leakage is severe, and the use stability is poor. Full-travel dual guide protection is conducted on the upper piston rod and the lower piston rod, and the work stability of the work roll bending and balancing device is effectively improved.

Device for loosely binding printed sheets to form booklets (10) using a loop-like wire binding element (41) comprises two C-shaping devices (50, 50') and two O-shaping devices (60, 60'). The C-shaping devices are positioned so that the initially flat wire binding element is bent into a C-shape. The O-shaping devices are positioned so that the C-shaped wire binding element is bent into a closed shape.
