[0039] Pressing rod 2 is provided with sliding slot 222, and sliding seat 221 is slidingly arranged in sliding slot 222, and connecting rod 22 is arranged between sliding seat 221 and down ring 3, and the both ends of connecting rod 22 are respectively hinged with down ring 3 and sliding seat 221, in the folding process of pressing rod 2, can drive down ring 3 to slide down along rebound apparatus main part 1, realize the linkage control to subsequent structure, and the rotation of pressing rod 2 is converted into the linear motion of down ring 3.

[0040] Pressing rod 2 is provided with mounting groove 232 on both sides, and steel ball 23 is slidingly arranged in mounting groove 232, and spring one 231 is arranged between steel ball 23 and mounting groove 232, and a plurality of limiting grooves 233 are formed in the inner side of L-shaped plate groove 211, spring one 231 can be embedded in limiting groove 233, and steel ball 23 in mounting groove 232 can be embedded in limiting groove 233 in the inner side of L-shaped plate groove 211 under the action of spring one 231.It can realize the limitation of the position of pressing rod 2 when rotating to a specific position, to ensure that pressing rod 2 does not shake randomly during detection.

[0041] The connecting ring one 42 is arranged on the rebound instrument body 1 in a sliding mode, and the connecting ring one 42 is arranged above the limiting sheet 11. A plurality of hinged seats 421 are arranged on the connecting ring one 42 in an array mode. The supporting leg 4 is hinged to the connecting ring one 42 through the hinged seat 421. The spring two 43 is arranged between the supporting leg 4 and the connecting ring one 42. After losing the constraint of the extrusion groove 5, the supporting leg 4 can be automatically unfolded under the action of the spring two 43.

[0042] The half circular plate 41 is arranged at both ends of the rotating shaft of the supporting leg 4. The arc-shaped plate 422 is arranged on the hinged seat 421. The half circular plate 41 can abut against the arc-shaped plate 422, so as to limit the rotating angle of the supporting leg 4, and avoid that the supporting leg 4 is excessively unfolded under the action of the spring two 43.

[0043] The connecting ring two 51 is arranged on the rebound instrument body 1 in a sliding mode. The extrusion groove 5 is arranged on the connecting ring two 51 in an array mode. The spring three 52 is arranged between the connecting ring two 51 and the connecting ring one 42. The extrusion groove 5 can be sleeved on the hinged seat 421. The inner side of the extrusion groove 5 can abut against the supporting leg 4. The extrusion groove 5 is driven to descend by the lower pressing ring 3. During the descending process, the inner side of the extrusion groove 5 can extrude the supporting leg 4, so as to rotate the supporting leg 4 around the hinged seat 421 on the connecting ring one 42, and complete the folding or unfolding action of the supporting leg 4.

[0044] It should be noted that the working principle of the dam strength destructive testing device for water conservancy projects is as follows: when in use, the connecting ring one 42 is sleeved on the rebound instrument body 1. At this time, the supporting leg 4 is in an unfolded state. The supporting leg 4 is erected on the detection point. The connecting cover 21 is sleeved on the rebound instrument body 1. The pressing detection is carried out. When folding is needed, the rebound instrument body 1 is held. The pressing rod 2 is pressed and folded. The pressing rod 2 enters the vertical state from the horizontal state. At this time, the pressing rod 2 rotates around the connecting cover 21 through the L-shaped plate groove 211. The sliding seat 221 in the sliding groove 222 on the pressing rod 2 drives the lower pressing ring 3 to slide downward along the rebound instrument body 1 under the action of the connecting rod 22. When the lower pressing ring 3 descends, the connecting ring two 51 and the extrusion groove 5 arranged in an array mode are pushed downward. During the descending process of the extrusion groove 5, the inner side of the extrusion groove 5 extrudes the supporting leg 4, so as to rotate the supporting leg 4 around the hinged seat 421 and complete the folding. At the same time, the spring two 43 between the supporting leg 4 and the connecting ring one 42 is compressed. When the pressing rod 2 rotates, the steel ball 23 in the mounting groove 232 on the pressing rod 2 can be embedded in the limiting groove 233 in the inner side of the L-shaped plate groove 211 under the action of the spring one 231. The position of the pressing rod 2 is limited, so that the pressing rod 2 and the supporting leg 4 complete the folding on the rebound instrument body, the occupied area of the device is reduced, and the folding is convenient.

[0045] When the pressing rod 2 is unfolded, the lower pressing ring 3 moves upward and separates from the connecting ring two 51, the spring three 52 between the connecting ring two 51 and the connecting ring one 42 makes the connecting ring one 42 separate from the connecting ring two 51, the supporting leg 4 loses the constraint of the extrusion groove 5 and is in the unfolded state under the action of the spring two 43, so that the supporting leg 4 on the connecting ring one 42 on the rebound instrument main body 1 is completely unfolded.

[0046] The above-mentioned embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that, for the ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application.
