The invention discloses a novel court fence. The novel court fence comprises a fence body, a fence frame body, a fence pull plate and a fence pressure plate, wherein the fence body is tightened through the fence pull plate; the fence pull plate has a long flat iron structure, penetrates through meshes of the fence body, and is fixed on the fence frame body through self-tapping and self-drilling screws; the section of the fence pressure plate is U-shaped; the fence pressure plate is pressed on the fence frame body; and a plurality of U-shaped holes are formed in the fence pressure plate. The novel court fence has the advantages of guarantee of athlete safety, convenience for mounting, firmness, difficult damage, lower cost, practicability and beauty.

The invention discloses a minitype rubber bag accumulator for a shock absorber. A cylinder barrel of a shock absorber compensation chamber is formed by connecting an inner cylinder barrel body and an outer cylinder barrel body into a whole through threads. A gas sealing screw plug is screwed tightly on an inflating sealing flange and arranged in a compensation cavity of the inner cylinder barrel body. The concave part of the bottom of a minitype rubber bag is radially fixed to a protrusion of the bottom end of the cylinder barrel of the shock absorber. Through a floating piston and a minitype rubber bag accumulator assembly installed under the flowing piston, complete isolation of a damping oil chamber and an inert gas chamber is achieved. Fold-type minitype rubber bag outer lugs are sleeved with fastening aluminum alloy flanges, the rubber bag and the fastening aluminum alloy flanges are connected through bolts and the inflating sealing flange, thus isolation of damping oil liquid and high-pressure gas is achieved completely, and oil-gas mixing is avoided. The defect of damping oil liquid flowing filling hysteresis is further overcome, and the idle stroke hidden danger of the shock absorber is avoided. The minitype rubber bag accumulator is different from a traditional rubber bag accumulator, the rubber bag and the damping oil liquid are isolated completely, aging is not liable to occur, the service life of the rubber bag is prolonged, the work responsivity is high through the fold-type appearance design, and the working load bearing ability and impact resistance are high.

The invention discloses a spoiler, a spoiler adapted to a hidden wiper, a spoiler adapted to install a high-position brake lamp, and an automobile. The spoiler includes an exterior part as an appearance part and a reinforcement The supporting part of the outer part includes a connecting part connected to the rear part of the vehicle body and a first accommodating part extending from the rear part of the vehicle body to the rear part; the outer part includes a first part and a second part, and the The second part extends from one end of the first part to one side of the first part and is folded back toward the first part until it is connected with the second side plate. The invention can ensure the strength of the spoiler, and has enough safety gap to avoid the fitted wiper, ensure the concealment of the wiper, and can ensure the detachability of the high-position brake light, and at the same time, pay attention to the aesthetics of the whole vehicle .

The invention discloses a refrigerator which comprises a box body, a door body and a yogurt machine. A refrigerating chamber is arranged in the box body. The door body is provided with a bar counter inner frame and a bar counter door used for opening and closing the bar counter inner frame. The door body is arranged on the box body. When the door body is closed, the bar counter inner frame is located in the refrigerating chamber. The yogurt machine is arranged in the bar counter inner frame and is provided with a controller used for automatically controlling the heating time of the yogurt machine. The refrigerator integrates the yogurt manufacturing function and is simple and convenient in manufacturing process. Moreover, manufactured yogurt is good in taste.

The invention belongs to the field of experimental equipment for the dynamic fracture toughness of a testing material and particularly relates to a three-point bending testing system based on the dynamic fracture toughness of the testing material. The system comprises a pedestal, wherein a support device, a loading rod, a knock rod, a compressed gas gun and a signal acquiring-processing device, a guide rail portion is arranged on the pedestal, and all the components are arranged on the guide rail portion and are fixedly connected and matched with the guide rail portion in a reciprocating guiding manner; the support device comprises a vertical plate which forms a matching portion matched with the guide rail portion, and grooves or through holes penetrating through a plate body are formed in the vertical plate; the support device further comprises a lining plate, and a through hole portion for being penetrated by the loading rod is arranged on the lining plate; lining units are further distributed on the lining plate; the supporting direction of the lining units, relative to a testing sample is opposite to the force applying direction of the loading rod. According to the system, the uniformity of acquired overall data can be guaranteed when the requirements of easiness in detaching and maintaining of a device are effectively realized.
