The invention discloses a bottom supporting device of a digital television, and relates to the technical field of digital television supporting equipment, the bottom supporting device comprises the digital television, and the bottom of the digital television is provided with a supporting piece; the supporting piece comprises a control table, the control table is located in the center of the lower portion of the digital television, adjusting strips are symmetrically connected to the two sides of the control table through adjusting pieces, the bottom of the digital television is aligned to the supporting piece, the adjusting strips are pulled, and angle blocks fixedly connected to the two ends of the two adjusting strips abut against the two sides of the digital television in a limited mode. The adjusting strip and the angle block move back under the resilience force of the spring to fix and limit the digital television, the digital televisions of different sizes can be effectively supported and fixed by adopting the mode, and after the digital televisions are limited and fixed by adopting the mode, the digital televisions can be conveniently fixed. The threaded connection block just faces a threaded installation hole, corresponding to the threaded connection block, in the digital television, installation of the digital television is facilitated, adaptability is wide, and the digital television is more practical.

The utility model discloses a high-capacity cat litter pad, which relates to the technical field of cat litter pads and comprises an upper-layer pad and a bottom-layer pad, the shape of the upper-layer pad is matched with that of the bottom-layer pad, three side edges of the upper-layer pad are welded with three side edges of the bottom-layer pad in a high-frequency manner, the upper-layer pad is a grid pad, and the bottom-layer pad is a grid pad. A plurality of grids and grid holes are arranged on the grid pad, a plurality of suckers are uniformly arranged on the bottom-layer pad, and the length of the upper-layer pad is larger than that of the bottom-layer pad. According to the utility model, the sucking discs are upwards welded on the non-porous plane foaming PVC backing material, and then the netted PVC foaming fabric is connected with the three sides of the plane backing material through a high-frequency welding process. Due to the unique design, the suckers can play a role in stably supporting the fabric, and the space volume between the backing material and the fabric is effectively increased.

The utility model discloses a kind of suction grain pipe offset suction grain machine, suction grain device and suction grain pipe are arranged on walking device, suction grain pipe is connected on rotating seat, can rotate around the center of rotating seat, suction grain pipe and rotating seat are offset in the angle position inclined outer side of suction grain device, suction grain pipe can rotate in the space range of adjacent two side surfaces of suction grain device around rotating seat center.The suction grain pipe and rotating seat of the utility model are offset in the angle position inclined outer side of suction grain device, increase the working surface range of suction grain, suction grain is more convenient and fast, less time-consuming, improve the efficiency of suction grain, reduce the requirement to space volume, more convenient to walk flexibly, also more convenient to store in warehouse, reduce storage cost.

The invention relates to the technical field of Bluetooth sound boxes, in particular to a Bluetooth sound box with an NFC quick pairing function, which comprises a sound box main body, a suction cup is arranged at the bottom of the sound box main body, a compensation device is arranged on the sound box main body, the compensation device is communicated with the interior of the suction cup, and the compensation device is used for extracting air in the suction cup; a control device is arranged on the sound box main body, the control device controls the start and stop of the compensation device according to the storage amount of air in the suction cup, the compensation device comprises a mounting seat fixedly mounted at the bottom of the sound box main body, and the suction cup is fixedly mounted at the bottom end of the mounting seat; a mounting cavity is formed in the mounting seat, a communicating hole is formed in the outer side wall surface of the mounting seat, and the communicating hole is communicated with the mounting cavity. The placement stability of the Bluetooth sound box on the placement plane is improved, and the problem that an existing Bluetooth sound box is low in anti-skid performance and reliability is solved.

The application discloses a conjugated crosslinking monomer, a solid-phase-free drilling fluid thickening agent, and a preparation method and application thereof. The conjugated crosslinking monomer has a stereoscopic alkyl structure and a conjugated diene structure, and is shown in the following formula. The conjugated crosslinking monomer is prepared by synthesizing an alkenyl compound with an adamantane compound in the presence of a catalyst. The conjugated crosslinking monomer is reacted with an alkenyl amide and an alkenyl sulfonic acid to obtain the solid-phase-free drilling fluid thickening agent. The thickening agent has good temperature resistance and salt resistance, and can improve the suspension and rock carrying performance of a clay-free drilling fluid system in a medium-deep well.
