Abstract:
An energy regenerative apparatus for a water hammer type pump includes a water hammer type pump and an engergy regenerative apparatus. The water hammer type pump includes a reservoir which is connected to a pump body by a pipe. A pressure tank is fixed on top of the pump body. A piston rod with a piston head is slidably provided in the pump body. A water passage between the pump body and the pressure tank is controllable by the piston head so as to control a flow of water from the pump body to the pressure tank. A flat valve is disposed between an outlet pipe and the pressure tank so as to prevent any reverse flow of water from the outlet pipe into the tank. A water gate valve is provided for controlling a water passage of the pump body. The energy regenerative apparatus includes a rack connected to a lower end of the piston rod and a pinion driven by the rack so as to drive a ratchet by means of a pair of rocker levels and produce a power output from an axle of the ratchet by means of an up and down movement of the piston rod of the water hammer type pump.

Abstract:
A structure of supporting shaft rod includes a retaining member having a retaining sheet and a retaining shaft rod; and a mobile supporting member having two supporting racks. The retaining shaft rod is inserted through a mobile buckling sheet and a retaining buckling sheet of two latching units. Each mobile buckling sheet has a pair of mobile protruding bumps. Each retaining buckling sheet has a pair of retaining protruding bumps corresponding to the pair of mobile protruding bumps. A wearing-resistant ring is located between the mobile buckling sheet and the corresponding retaining buckling sheet. The retaining shaft rod is inserted through the wearing-resistant ring. An outer circumference of the wearing-resistant ring is located between interior surfaces of the pair of mobile protruding bumps of the mobile buckling sheet and the pair of retaining protruding bumps of the corresponding retaining buckling sheet and an exterior surface of the retaining shaft rod.

Abstract:
The present invention discloses an anti-pinching structure for supporting frame, in which a slidable or rotatable positioning block is disposed on the hinge portion of the connection base and the supporting framework and a hinge unit is disposed on the hinge portion of the connection base and the supporting framework, such that the torsion spring of the hinge units may form a supporting torsion against the supporting framework and the positioning block may prevent the supporting framework from springing back.
Abstract:
The present invention relates to a structure of supporting rotation shaft, comprises a retaining member, a surface of a retaining sheet of the retaining member is protrudingly provided with a pair of sheet flanks that allow a retaining shaft rod pass through, two ends of the retaining shaft rod are respectively provided with a resilient supporting unit, two ends of each of the resilient supporting units are respectively connected to the retaining member and a mobile supporting member; the mobile supporting member mention above, two lugs adjacently to the corresponding resilient supporting units are protrudingly provided on two top ends of two supporting racks of the mobile supporting member, each of the lugs is passed through by the retaining shaft rod, two ends of the retaining shaft rod are respectively provided with a latching unit, each of the latching units is composed by a mobile buckling sheet provided at the outer side of each of the lugs and a retaining buckling sheet that allows the retaining shaft rod pass through and be positioned, two opposite surfaces of one of the mobile buckling sheets and the corresponding retaining buckling sheet are respectively and protrudingly provided with a pair of mobile protruding bumps and a pair of retaining protruding bumps, two ends of the retaining shaft rod are further and respectively provided with at least one resilient unit and then is connected to an end sealing member; by pulling the mobile supporting member, the pair of mobile protruding bumps of one of the mobile buckling sheets pass across the pair of retaining protruding bumps of the retaining buckling sheet provided adjacently to the mobile buckling sheet, so a storing status of the mobile supporting member is released and an initial operation status is therefore formed.
