New description: 【New technical field】 Especially refers to an adjustable slowness. This new type is a gas pressure bar with a pressure bar effect. [Prior Art] As shown in Fig. 1, the general viscous bar of the adjustable buffering force is larger than the outer tube mechanism 11, and the axial assembly is performed on the outer tube mechanism u. The throttle piece _13 on the piston mechanism 12 and the adjustment mechanism 14 mounted in the piston mechanism 12 are provided. The outer tube mechanism 汲111 is internally displaced by an axially displaceable tube-oil pressure chamber 112: the valve 112 is partitioned into a piston 121 spaced apart from one another, and an inner tube 122 assembled on the piston (2). And one:; and protrudes from the outer f U1 outside the actuating rod 123, the piston is called the oil pressure chamber is divided into one of the upper and lower intervals, the first and the second interval 1, 2, 1G3 ' and has a majority of connectivity The inner tube 122 of the first guiding hole 105' of the sections 1G2 and 1G3 has an oil guiding passage (10) communicating with the second zone fa1 1() 3, and a plurality of radial communicating first-intervals 1〇2 and the oil guiding passage 1〇 The second guide hole 107 of 6. The β-throttle flap mechanism 13 is axially displaceable elastically against the top surface of the piston (2), and partially covers the first guide hole 1G5 to open π, and the adjustment mechanism 14 is axially displaceably assembled to the inner tube 122. With the action rod 123, the gas C rod can be changed between the full buffer state and the half buffer state. In other words, by adjusting the adjustment mechanism 14' to change the speed of the oil body flowing between the sections 102 103, the gas pressure bar can have a different buffering capacity in the full buffer state and the half-level state. The buffer recovery speed is 5 M309034 degrees'. However, the structure of the adjustment mechanism 14 of the gas pressure bar can only reduce the buffering effect by adjusting the adjustment mechanism u, but cannot completely close the buffer function. Therefore, there is still inconvenience in use. And need to be improved. [New content] ϋ Therefore, the purpose of the present invention is to provide a gas pressure bar with multiple impulses. , You Heng

The upright inner tube 42 that is fixed to the center of the piston 41 and the bottom end portion of the piston 4 are fixed to the top end portion of the inner tube 42 and go out of the outer tube 3" The piston 4 is spaced around its axis and extends axially through the first guide hole 4iq. The section of the inner tube 7 M309034 42 near the piston 4 has a partitioning convex portion 421 which protrudes radially outward and is airtightly supported against the inner circumferential surface of the outer tube 31, and the partitioning convex portion 421 is matched with the piston μ. The oil dust chamber 310 is partitioned into a first soil section 311 located below the piston 41, a second section 312 between the piston 41 and the partitioning convex portion 421, and a third section located above the partitioning convex portion 421. 313. The inner circumferential surface of the inner tube 42 extends around the boundary axial direction and the bottom end of the first first section is connected to the oil guiding passage 422, and has a plurality of radially extending communication between the second section 312 and the second guiding hole of the oil guiding passage 422. And a plurality of radially extending communication third sections 313 are similar to the third pilot holes of the oil guiding passages 422. The oil guiding passage 422 has a through portion 423 extending from the bottom end surface of the inner tube 42 and communicating with the second guiding hole, a top portion extending upward from the lower through portion and communicating with the third guiding hole 427 and having a larger diameter The upper passage section Μ3 is similar to the upper passage section, and the lock passage surface 425 between the lower passage section 423 and the upper passage section 424. The actuating rod 43 is fixedly connected to the upper passage portion 424 and fixed to the top end portion of the inner tube. The movable door 7-piece mechanism 5, including the sleeve, is placed at the bottom end portion of the inner portion f42 and abuts against the opposite side.

In this embodiment, After the gas cylinder valve 314 is placed in the outer tube 31, the gas pressure chamber 314 has a high pressure gas in the pressure chamber 34 by compressing the gas in the outer tube 31. In addition, the gas pressure rod is assembled. After that, the first section 311 of the oil pressure chamber 3 is filled with oil body (not shown) via the airtight assembly 32, and the fluid pressure in the air pressure chamber 314 is greater than the oil pressure chamber. 31〇, since the fluid infusion mode of the chambers 31〇, 314 is not the focus of the present invention, it will not be described in detail. When the gas pressure rod is used, the joint 33 of the outer tube mechanism 3 and the piston mechanism 4 can be actuated.

The state, the half buffer state and the one lock state change. As shown in Figs. 4 and 5, when the gas pressure bar is in the full buffer state, the lower oil passage 422 and the oil pressure chamber 31 are the same as the oil pressure chamber 31. When a section si} M309034 is connected, and the upper and lower pass sections 424, 423 are mutually affected by the axial vibration force, the actuating rod 43 can be relatively but the second = Γ 2: wide relative to the outer tube 31 is moved downward, and the relative compression is _ 34, the oil body of the si-section 311 is simultaneously moved toward the oil and gas separation valve 34, so that the air pressure chamber 314 is shrunk and accumulated.

When the sleeve-to-vibration force disappears, the restoring force of the air pressure chamber 314 is forced to push the piston 41 upward, so that the oil body of the living room 311 is upward, as shown in FIG. 4, the first, and the action will be via The guide holes 41〇, like the oil body of the section Μ2, 313, and the oil passage 422, are returned to the section 31, and the gas pressure bar is again provided with a buffering capacity. As shown in Figures 3, 6, and 7 - If you want to adjust the air pressure bar from the buffer to the semi-buffer, you only need to move the adjustment member 相对 relative to the actuating rod 43 to force the push rod 62 to move down. "1' until the first resistance of the control pin 61 10 M309034 The plug section 6U blocks the opening of the lower passage section 423 and the first section 3ιι, the air pressure bar is in a half-buffer state. Acting on the vibration force, so that the piston ... is pushed down by the private pressure, the oil separation valve 34 will also be moved downwards to compress the air pressure chamber, and the opening of the passage through the oil passage 422 is closed. The oil body of the interval 3 ιι will only flow through the ^ 41G, and move up the throttle ϋ 51, 52, and sequentially through the interval 312, the second guide hole 426, the oil guide channel and the third guide The hole 427 flows to the third section 313. As shown by the arrow ΗΗ in FIG. 7, the lower passage section is cut, the opening is closed, and the second blocking section 612 of the control pin 61 is moved downward to make the upper passage #424 space shrink. The relationship between the oil body flowing to the second and third intervals / 12, 313 will be significantly slower than the full buffer state, with the air dust bar The buffering capacity is poor. ^When the vibration force disappears, the oil and gas separation valve 34 will move up and reset, and the oil body of the =1311 will force the piston 41 to move up and reset. At this time, the piece 5 52 will also be reset. The top surface of the piston 41, and the oil bodies of the third and third sections 313 and 312 can only pass through the diversion gap 510 of the first throttle piece 51, etc., and the diameter is smaller than the first guide hole 410. In the middle, because the oil field is 41 〇 small, the oil body return speed will be slower than ',, and slow', which will cause the buffering capacity of the gas pressure bar to recover slowly. As shown in Figures 3 and 8, when the gas is to be repeated When the bar is adjusted from the semi-buffered state to the closed state, 'only (four) ❹ the actuating lever 43 goes down until the control pin 61 篦 阳 阳 抓 r 丨 It ' oil lock 422 lock surface - 425 2 bottom end to the lower limit When the closed lower passage portion 423 and the upper passage portion 424 11 M309034 are in contact with each other, the air pressure rod is located in the locked state. The opening of the oil guiding passage 422 communicates with the first interval 3U, and The communication between the lower passage section 423 and the upper passage section 424 is closed, so that the gas pressure bar is subjected to the vibration force, and A body section 311 of the oil can not flow to the other sections 312, 313, the actuator rod are not retracted into the outer tube 31 'and thus the air pressure rod completely non-buffering capacity.
