The invention relates to the technical field of foaming product preparation, provides a foaming product with an invisible massage structure, and solves the technical defects of pressure concentration, use discomfort, uneven surface, limited application scene and infirm interlayer combination of the existing massage foaming product. In addition, the invention further provides a preparation method of the foaming product with the invisible massage structure, and the defects that an existing foaming product preparation process is uncontrollable, and precise forming and integrated stable combination of double-layer materials cannot be achieved are overcome. The foaming product comprises an upper layer and a lower layer which are integrally foamed and formed, the lower layer is provided with a massage structure protruding upwards, the upper layer wraps the massage structure, touch generated by the massage structure is buffered by the upper layer and then transmitted to the upper surface of the product, and therefore soft massage with the flat surface is achieved. The invention is widely applicable to the fields of shoes, sitting and lying appliances, sports protection and the like.

The utility model relates to a drilling rod grabbing manipulator, and belongs to the technical field of coal mine automatic drilling equipment. The manipulator is mainly composed of a fixing mechanism, a horizontal displacement mechanism, a lifting joint, an overturning joint, a telescopic joint and a gripper joint. The fixing mechanism is connected with the moving platform through connecting points arranged at intervals, the horizontal displacement mechanism achieves accurate horizontal movement through a linear guide assembly, and all joints work cooperatively through modular design. The mechanical arm is characterized in that the mechanical arm and the drill rod box are completely separated, the drill rod box can be independently and rapidly replaced, and the mechanical arm does not need to be adjusted. By means of the design, the adaptability of equipment to drill rods of different specifications is remarkably improved, the drill rod replacement process is simplified, meanwhile, the stability of the mechanical arm under the heavy load working condition is enhanced, accurate control over drill rod grabbing, lifting, overturning and conveying is achieved, and the mechanical arm is suitable for large-specification drill rod loading and unloading operation of a high-power directional drilling machine. The device has the technical advantages of compact structure, convenient operation and high reliability.

This invention relates to the field of roof-mounted lift tent technology and discloses a bed board extension structure based on a roof-mounted lift tent. The structure includes a base, a canopy mounted on the base, a sliding support drive between the canopy and the base, a flip-up bed board mounted on the side of the base, and locking components and fixing linkages mounted on the canopy and base. The cross-support rod assembly of this invention, relying on the dynamic changes in structural form during the lifting process, achieves a dual improvement in support stability and load-bearing capacity, exhibiting significant force advantages. When not raised, the structure is easily compressible. As the canopy rises, the sliding end of the supporting rod gradually moves towards the center and becomes increasingly vertical, reducing the vertical angle and increasing the lateral angle. This allows the triangular support frame structure to form an efficient axial force characteristic, significantly weakening the bending moment effect and improving compression resistance. After reaching the highest position, the structure, combining its geometric shape and the central arrangement of the sliding end, forms a naturally stable structure that can effectively resist longitudinal pressure and lateral off-center loads.

The utility model relates to a kind of PCB antenna structure compatible with multiple packaging types, including PCB board, at least two different packaging types of antenna elements being set on the PCB board, and with the chip being connected to the antenna element;The signal pin of the antenna element is connected to the same function pin of the chip in parallel, and the packaging layout of the two antenna elements on the PCB board is pin overlapping arrangement;Wherein, the pin pad of the antenna element adopts overlapping design in PCB layout, and pad size, spacing is consistent, so that only one antenna element is welded when actual patch.
