The invention discloses a hinge. The hinge comprises a hinge main body, a coupling component, a movable seat and an elastic component, wherein the coupling component is connected with a swinging block in a meshing manner, and forms a coupling relation with a buffering component of the hinge main body; the coupling component is also in pivot connection with the movable seat through a pivot connection part at one end; a rocker arm is arranged on the position, adjacent to the movable seat, of the coupling component in a pivot manner; one end of the rocker arm is arranged on a third shaft rod of the hinge main body in a pivot manner; a connecting hole of the elastic component is used for the passing of the third shaft rod of the hinge main body; two supporting ends are formed by equi-directionally extending from both sides of the connecting hole; the supporting ends are against the bottom wall surface of the hinge main body; an against end, which is located at the same side as the supporting ends, is convexly extended from the middle of the elastic component; and the against end is against the bottom surface of the coupling component. Through the structure, the hinge can generate free travel route and buffering travel route with proper angles, thus the effects of reducing the impact force and noise while opening and closing door plates are achieved.

The utility model relates to liquid storage equipment with a cleaning device. The liquid storage equipment with the cleaning device comprises a barrel body and the cleaning device, wherein the barrel body comprises a peripheral wall and a bottom wall arranged on the bottom edge of the peripheral wall; the peripheral wall and the bottom wall surround to form a liquid storage space; the cleaning device comprises a main shaft, a drive device, a support fixedly arranged on the main shaft, at least one cleaning element, a baffle unit and a plurality of ball brushes; the main shaft extends into the liquid storage space along the axial direction; the drive device is used for driving the main shaft to rotate; the cleaning element can be arranged on the support in a pivot pendulum way; the pivot pendulum axis of the cleaning element is parallel to the main shaft; the cleaning element is provided with a flow resistance plate, a cleaning brush and a connecting unit connected to the flow resistance plate and the cleaning brush; when the drive device does not work, the cleaning brush and the ball brushes cannot cling to the inner wall of the barrel body, so that the elastic fatigue is delayed.

The invention discloses a double-clip glasses hinge. The double-clip glasses hinge comprises a hinge connector, a hinge tongue and a first clip. The hinge connector comprises a hinging part and a fixing part. The hinge part is provided with a hinge tongue containing groove. The hinge tongue is arranged in the hinge tongue containing groove and is hinged to the hinging part. The fixing part is provided with a first clip containing hole, and the first clip containing hole is communicated with the hinge tongue containing groove. The two ends of the first clip are a rear fixing end and a front outward ejecting end respectively. The rear fixing end of the first clip is arranged in the first clip containing hole. The front outward ejecting end of the first clip is arranged between the hinge tongue and the hinge tongue containing groove. A second clip used for preventing the first clip from being ejected outwards is further arranged on the hinge connector. The second clip comprises a connecting part and a blocking part. The connecting part is fixedly connected with the fixing part. The blocking part is arranged on the outward ejecting side of the first clip in a surrounding mode. The double-clip glasses hinge can limit a glasses arm stably and is long in service life.

The invention discloses a rotary three-section balancing head earphone wire, which comprises a male plug, a female plug, a C-shaped clamp spring and an earphone connecting wire. The male plug is provided with an insertion part, a first circular groove, a concave surface, four contact parts, an insulating layer, an arc convex surface and a second circular groove. The plug-in part of the male plug of the invention can be rotated in three sections in the female plug. When the male plug rotates for one section, the earphone connected with the earphone connecting wire can play a sound effect. Whenthe male plug rotates for three sections, the earphone can play three different sound effects respectively. The earphone has the advantages of fast audio transmission speed and high sound quality definition. And the male plug can be easily disassembled or assembled with the female plug through the C-shaped card spring, The utility model has the advantages of high assembling efficiency and convenient assembling, and solves the problems that the male and female plugs in the headphone cable are integrally formed, and the utility model has the advantages of single use, the male plugs can not be rotated, the audio transmission speed is slow, the sound quality effect is poor, and only one sound effect can be played, and the like.

The invention relates to a general-purpose engine with low exhaust gas emission, comprising a general-purpose engine case body, a cylinder head and a cylinder cover, wherein a cavity between the cylinder head and the cylinder cover is a rocker arm chamber; a muffler is communicated with an exhaust port of the cylinder head through an exhaust pipe; a crankcase cavity of the case body is communicated with the rocker arm chamber at the upper end of the cylinder head through an air duct; the cylinder cover is provided with an air inlet hole for communicating the outside with the rocker arm chamber; a one-way valve which is opened at negative pressure is arranged at the air inlet hole; and the cylinder cover is also provided with an air outlet which is communicated with the muffler through a one-way valve which is opened at positive pressure. Fresh air can be sucked into the rocker arm chamber for storage by the negative pressure formed in a crankcase when a piston of the engine reciprocates and the stored fresh air can be forced to be sent to the muffler by the positive pressure formed in the crankcase when the piston of the engine reciprocates, thus HC, CO and NOx in high-temperature exhaust gas exhausted from the engine can undergo fully chemical reaction with sufficient oxygen in the muffler and then can be exhausted, and the exhaust gas emission of the general-purpose engine can be effectively reduced.

A decoration ribbon comprises a ribbon member formed with a first surface and a second surface, a first fastening band and at least one decorative object; the first surface or the second surface at one end of the ribbon member is disposed with a first fibriform pile fabric structure or a first micro-fibriform loop fabric structure of the first fastening band; the second surface or the first surface at another end of the ribbon member is disposed with the first micro-fibriform loop fabric structure or the first fibriform pile fabric structure of the first fastening band, and the at least one decorative object is combined on the first surface of the ribbon member; when the first fibriform pile fabric structure is adhered and fastened with the first micro-fibriform loop fabric structure, the ribbon member is formed as an annular member for wrapping a plate to be decorated.
