Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] As shown in the figure, a foldable piston reset device includes a rod body 11, a rotating connector 12, a propulsion mechanism 13, and a contact head 14. The rod body 11 is composed of several sections of folding rods 11-1, and two adjacent The folding rods 11 - 1 are connected by a rotating connecting piece 12 .

[0021] The rotating connection part 12 arranged at the tail of the folding rod 11-1 and the head of the next folding rod 11-1 includes a rotating connected insert pa...

Abstract

The invention discloses a foldable piston reset device. The foldable piston reset device comprises a rod body, a rotary connecting piece, a clamping mechanism and a pushing mechanism, wherein the rodbody is formed by sequentially connecting a plurality of folding rods end to end, the rotary connecting piece comprises a groove piece and an inserting piece which are connected in a rotary mode, theclamping mechanism comprises a rotating piece and an elastic piece, the elastic piece is connected with the rotating piece, a protrusion is arranged on a surface of the rotating piece, an open grooveis formed in the position, corresponding to the protrusion, of the shell of the inserting piece, a clamping groove which is formed in the groove piece and clamped with the protrusion is further comprised, the pushing mechanism comprises a first push rod and a second push rod which are perpendicularly connected, the second push rod is parallel to the folding rods, the other end of the second push rod makes sliding contact with the rotating piece, and the other end of the first push rod stretches out of an outer side of the folding rods. The device is advantaged in that the device is simple in structure, easy to operate, stable in mechanical property, capable of meeting the reset requirements of pistons at different distances and high in practicability.

Description

technical field [0001] The invention belongs to the field of dredging instruments, in particular to a foldable piston reset device. Background technique [0002] The test device for simulating the shock stress wave uses a piston hitting a baffle to generate a shock wave. After the impact, the piston will stay in a certain position in the launch tube after hitting the baffle, and cannot automatically return to the original position. In this case, the connecting flange of the launch tube is usually disassembled, and the piston is manually pushed back to its original position before the next test can be performed. This operation is time-consuming and laborious, which greatly hinders the test process. At the same time, limited by the special structure of the launch tube, it is impossible to use conventional tools to reset the piston from the observation hole, so a device is urgently needed to solve this problem. Contents of the invention [0003] In view of the above proble...
