The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.

Refer to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 5, the suspended shock-absorbing of engineering automobile seat of the present invention, comprises base frame welding body 1, slide rail connecting panel 2, the first rotating plate 3, the second rotating plate 4, rotary connection sheet 5, the first adapter shaft 6, the second adapter shaft 7 and Compress Spring 8.Slide rail connecting panel 2 is arranged on base frame welding body 1 below, one end connecting sliding rail connecting panel 2 of the first rotating plate 3 or the second rotating plate 4, the first rotating plate 3 is fixed on one end of the first adapter shaft 6, the second rotating plate 4 is fixed on one end of the second adapter shaft 7, rotary connection sheet 5 connects the first rotating plate 3 and the second rotating plate 4, the other end of the other end of the first rotating plate 3 and the second rotating plate 4 is connected by Compress Spring 8, the first adapter shaft 6 and the second adapter shaft 7 are all arranged on base frame welding body 1, the first adapter shaft 6 and the second adapter shaft 7 be arranged in parallel, the first adapter shaft 6 or the second adapter shaft 7 are bow-shaped structural.When base frame welding body is stressed, is equivalent to operator while moving down and sits on the seat, the first rotating plate connecting, the second rotating plate is stressed around pivot point, rotates, Compress Spring is compressed, now being rotated down motion is blocked, play shock damping action, when bounce stress balance that operator's body weight and Compress Spring provides, seat is in suspended state, namely the comfort conditions of operator in being seated; When external force is cancelled, Compress Spring resilience, base frame welding body resets.The present invention is simple in structure, can realize easily the suspension damping of engineering automobile seat, improves operator's level of comfort.

Refer to shown in Fig. 4 and Fig. 5, also comprise the 3rd rotating plate 32, the 4th rotating plate 42, the second rotary connection sheet 52 and extension spring 9, the other end of the first adapter shaft 6 is provided with the 3rd rotating plate 32, the other end of the second adapter shaft 7 is provided with the 4th rotating plate 42, one end of the 3rd rotating plate 32 or the 4th rotating plate 42 one end connecting sliding rail connecting panel 2, the three rotating plates 32 are connected by extension spring 9 with the 4th rotating plate 42.Wherein, the first rotating plate 31, the second rotating plate 41, the second rotary connection sheet 51 and slide rail connecting panel 2 form the first four-bar linkage, and slide rail connecting panel 2 is connecting element, and other 3 is movement parts; The 3rd rotating plate 32, the 4th rotating plate 42, the second rotary connection sheet 52 and slide rail connecting panel 2 form the second four-bar linkage, and slide rail connecting panel 2 is connecting element, and other 3 is movement parts.2 four-bar linkages are realized and being synchronized with the movement by the first adapter shaft 6 and the second adapter shaft 7.Wherein, upper the first rotating plate 31 of first connecting rod mechanism is connected by Compress Spring 8 with the second rotating plate 41, and upper the 3rd rotating plate 32 of second connecting rod mechanism is connected by extension spring 9 with the 4th rotating plate 42.When base frame welding body be stressed (being equivalent to operator sits on the seat) while moving down, the first rotating plate connecting, the second rotating plate, the 3rd rotating plate and the 4th rotating plate is stressed around pivot point, rotates, extension spring is elongated, Compress Spring is compressed, now being rotated down motion is blocked, play shock damping action, seat is in suspended state, namely the comfort conditions of operator in being seated; When external force is cancelled, extension spring and Compress Spring resilience, base frame welding body resets.

Refer to shown in Fig. 1, Fig. 3 and Fig. 5, also comprise that body weight regulates parts 10, body weight regulates parts 10 to connect Compress Spring 8 and the first rotating plate 3 or the second rotating plate 4.Body weight regulates parts for regulating the pre compressed magnitude of Compress Spring, and it can be according to the difference of operator's body weight, by regulating the pre compressed magnitude of Compress Spring, to reach best suspension effect.

Owing to there being suspended shock-absorbing on seat, the vibrations that engineering truck produces when transportation and operation can be absorbed and weaken while transmitting, and have realized shock-absorbing function.
