The invention discloses a heat preservation and sound insulation device for fabricated building wallboard decoration. The device comprises a wall body plate, wherein a second groove is formed in one side of the wall body plate, two first grooves are symmetrically formed in one side of the wall body plate, fixing plates are arranged on the inner side walls of the two first grooves, and four bolts are symmetrically connected to one sides of the two fixing plates in a threaded mode. According to the device, the heat preservation capacity of the wall body plate can be improved through a heat preservation layer, the sound insulation effect of the wall body plate can be improved through a sound insulation plate, the sound insulation plate in the device is of a detachable pull-away structure, anoperator can fix and detach the sound insulation plate by fixing and detaching the fixing plates, the top and the bottom of the sound insulation plate slide into two guide rails, the sliding smoothness is improved through pulleys, and when four inserting rods are connected with second inserting grooves in an inserted mode, the two fixing plates in the sound insulation plate are fixed into the twofirst grooves of the wall body plate through bolts.

The invention provides a photovoltaic (PV) tracking system and a guide bearing structure therefor. The guide bearing structure includes a swing beam, and at least one supporting plate which is vertically connected below the swing beam; the swing beam is connected with the supporting plate through brackets, and the brackets are provided with rollers; an arc-shaped sliding groove is arranged in a side face of the supporting plate, and the rollers slide in the sliding groove to drive the swing beam to rotate about the axis. Furthermore, the PV tracking system includes a PV tracker, and a PV component which can convert light energy into electrical energy. According to the invention, the moment of driving the PV component to rotate is reduced by means of friction rotation between the components of the guide bearing structure, and the lubricating oil for assisting rotation can be avoided, so that the service life of the bearing structure is prolonged. The installation of the PV tracking system is simple, the power generation capacity can be effectively improved, and the labour cost is reduced.

A slide rail assembly includes a first rail, a second rail, a third rail, a first supporting assembly and a sliding auxiliary assembly. The first supporting assembly is arranged on the first rail for supporting the second rail. The sliding auxiliary assembly is movably mounted on the second rail, and includes a plurality of balls for supporting the third rail.

The invention discloses a handwriting map cache achieving method and belongs to the technical field of handwriting maps. The handwriting map cache achieving method specifically comprises the steps: a cache device reads and stores a preset standard map in a storage device in advance; a handwriting catching device catches handwriting information produced by a used in sliding operation in real time and sends the handwriting information to a processing device; a processing device retrieves the standard map pre-stored in the storage device according to instantaneous handwriting information and performs corresponding scaling to obtain a specific handwriting map; the processing device sends the scaled handwriting map to a drawing device; and the drawing device receives the handwriting map and draws a real-time handwriting image on a display interface of a display device according to the handwriting map. The handwriting map cache achieving method has the advantages that the handwriting map in caching is red in real time, real time scaling is performed, sliding fluency of the user is improved, the standard handwriting map is stored in the storage device, and a storage space is saved.

The invention discloses an anti-sticking die structure for a large-sized sliding block. The anti-sticking die structure comprises a die plate and the sliding block. The sliding block is movably mounted in a sliding block groove formed in the die plate. Sliding devices are arranged inside the die plate, and comprise pressing blocks, bearing pedestals, elastic parts and bottom surface bearings. The bearing pedestals are positioned at the tops of the pressing blocks. The elastic parts are mounted between the pressing blocks and the bearing pedestals. The bottom surface bearings are mounted on the bearing pedestals, and are matched with the bottom of the sliding block in a sliding manner. The sliding block is jacked up to be suspended on the die plate under the action of the elastic parts. A gap is reserved between one of the step surfaces on two sides of each bearing pedestal and the die plate. Sliding block steps are respectively formed on the two sides of the sliding block. Slide wedges positioned in the sliding block groove are respectively formed on two sides of the sliding block. A gap is reserved between each slide wedge and the sliding block. The anti-sticking die structure can solve the problem that the large-sized sliding block is stuck in the die plate. Besides, side bearings and step surface bearings are arranged on the slide wedges, so that the friction coefficients are further reduced, and the sliding smoothness of the large-sized sliding block on the die plate is improved.
