A hammer includes a handle, a hammer body mounted on an end of the handle and having a side formed with a combination bar inserted into the handle, and a protective jacket integrally formed on the handle to encompass a periphery of the combination bar and a mediate portion of the hammer body entirely. Thus, the protective jacket of the handle encompasses the periphery of the combination bar and the mediate portion of the hammer body entirely, so that the handle and the hammer body are combined with each other rigidly and stably, thereby enhancing the combination strength of the hammer.

The invention belongs to the technical field of power generation, and particularly relates to a pedal type piezoelectric power generation apparatus and method. The apparatus is characterized by at least comprising a pedal, a cover plate, a circular arc-shaped framework and a circular arc-shaped cavity body, wherein a rectangular groove is formed in the pedal; two supporting blocks are fixed at the left and right ends of the rectangular groove of the pedal; the two supporting blocks are used for supporting the cover plate; the sum of the supporting blocks and the height of the cover plate is equal to the depth of the rectangular groove; the supporting blocks and the cover plate are fixedly connected through screws; the shape of the inner circular arc-shaped surface of the circular arc-shaped framework is the same as that of the bottom circular arc-shaped surface of the circular arc-shaped cavity body; the circular arc-shaped inner surface of the circular arc-shaped framework and the bottom circular arc-shaped surface of the circular arc-shaped cavity body are fitted; and the circular arc-shaped framework, the circular arc-shaped cavity body and the pedal are connected through bolts, nuts and springs. The pedal type piezoelectric power generation apparatus is simple in structure, low in use cost and wide in application range.

The invention relates to a hollow composite tire structure. The structure comprises an outer tire, a first cavity and a second cavity are formed in the outer tire, and the first cavity is formed in the circumferential direction of the outer tire; and the second cavity is also arranged in the circumferential direction of the outer tire and is provided with an inward opening. The first cavity and the second cavity are formed in the outer tire, so that the deformation space of the outer tire is increased, and the damping effect of the outer tire is improved.

An electric connector comprises an insulating body and a plurality of terminals housed in the insulating body, wherein the insulating body is provided with side walls and a plurality of terminal slots; the terminal slots are provided with bottom walls; terminals are provided with arms hanging above the bottom walls; the bottom walls are provided with upper surfaces facing the arms; the bottom walls of the insulating body are provided with vias running through the bottom walls; and the upper surfaces of the bottom walls obliquely extend so that the bottom walls become thinner and the height ofthe insulating body can be reduced while providing the deformation space of the arms.

The present invention relates to the field of radome, in particular to a low-density glass fiber reinforced plastic radome and its production process, comprising a first protective cover and a second protective cover enclosed in the shape of a hollow water tower, arranged on the first protective cover and the second protective cover The antenna holding rod in the formed hollow water tower-shaped cavity; the first protective cover is provided with a first engaging member, and the second protective cover is provided with a second engaging member corresponding to the first engaging member of the first protective cover, The first engaging part is connected with the second engaging part so that the first protective cover and the second protective cover are detachably connected to form a hollow water tower-like structure, and the surface of the second protective cover is provided with an openable window for easy maintenance ; The high wave-transmitting fiber cloth layer includes a composite core-spun gauze formed by weaving carbon fiber core yarn and glass fiber woven yarn, and a cured resin cured on the outside of the composite core-spun gauze. The FRP of the invention has the advantages of low density, light weight, small dielectric constant, good wave permeability, high mechanical strength and long service life.

The invention discloses a piezoelectric self-power-supply positioning shoe. The piezoelectric self-power-supply positioning shoe comprises a sole and a vamp, wherein a power module, a control module, a GPS positioning module and a wireless communication module are arranged in the sole. The power module comprises a piezoelectric power generation unit and an energy storage unit. A compressive deformation region is arranged on the sole. The piezoelectric power generation unit comprises a press block and a piezoelectric body, wherein the press block makes contact with the compressive deformation region and is matched with the compressive deformation region, the piezoelectric body is driven by the press block to deform so as to generate electricity, and the piezoelectric body is fixedly arranged in the sole and connected with a circuit of the energy storage unit. Under the action of gravity of a human body, the compressive deformation region deforms, the press block which makes contact with the compressive deformation region drives the piezoelectric body to deform due to the fact that the press block relatively shifts, different electric charges are generated by the piezoelectric body in the deformation process, the electric potential difference is formed, and therefore in the process that a wearer walks, the piezoelectric body continues generating electricity, electric energy is stored in the energy storage unit, the control module, the GPS positioning module and the wireless communication module can be continuously driven to work without restriction of the time and natural conditions, and positioning information of the wearer is provided for the outside world.
