The damping unit is to provide the cushioning function, mainly utilizing the relative movement between a rubber sleeve and a sliding member to provide a resistance force against the movement to achieve the cushioning effect without using fluid as a source of cushioning resistance, thereby completely solving problems of oil or air leakages occurred in conventional pneumatic or hydraulic devices.

Description

Fifth, the bad result is usually made after the delay is made. [Explanation of the invention with oil (1) Field of the invention] The present invention relates to MM and buffer damping. Background of the invention] The slow balance stick is generally a switch of a bucket, and it does not emit a giant; and it is used for other purposes, and it needs to be mentioned. Generally speaking, it is slower than a kind of buffer stick. 'Especially a fluid that is not used for moving parts needs to use fluid as a buffer medium. There are some conventional pressure-type tubes, but the impulse resistance makes follow-up regardless of maintenance and invention of the fluid. The pressure-type leakage mechanism and the oil pressure buffer rod are basically the source of the previous proposal. The supplementary fluid is used for cleaning. The purpose and outline are mainly used to solve the problem of buffering oil and gas leakage. You can make a large noise machine to fight against the root of the punching rod. The biggest is the old one. Therefore, the method or operation is difficult to describe.] The purpose of the problem caused by the above force is to open and close the door, Even the pieces are a hindrance to movement. According to the internal pressure, the shortcomings are some solutions to the leakage. The oil pressure is no better than heaven. The source of the problem can be raised, but can provide a moving mechanism, which can cause the door or the sample, in addition to the force, to reach the buffer resistance rod or the oil leaks the oil or the gas or the leak or the air pressure is subject to the staleness. Causes a considerable speed to move slowly is the source of the door frame to provide back buffer resistance pressure bar. The solution of leaking oil and other fluids can be divided into two problems: when it is large, it is inherently uncontrollable, and when it is closed again, the effect of the loss of the force is reduced. The solution is to limit it. B provides a buffer rod. It is not necessary to completely solve the traditional air pressure type or a kind of buffer rod.

Shaft, elastic element (the most common one is spring? 〇, the following is only used as an example), and the damping unit 80, the hollow tube body is one The hollow body has a space inside, the top end has a connector 51 on the outside, and the spring 70 is installed in the hollow tube body 50, and the bottom end of the shaft center 60 abuts on the spring 70 and is installed in the hollow. Inside the pipe body 50, and the outer diameter * inner diameter of the shaft center 60 can slide relative to the hollow pipe body 50, and by the return, the bottom end of the shaft center 60 has another connector 61, so that The connectors 5 1 and 6 1 are connected to the object that needs to be buffered. The bottom end of the hollow body 50 is only exposed by the shaft center 60 to prevent the spring 70 from detaching. The damping unit 80 is installed at the bottom end of the shaft center 60 and is located at ㈤ Between the sanitary pipe bodies 50, it contains Thai w 1 ^ ^ ^ ^ ^ „, dagger page 81% and sliding member 82, and the collar 81 is also composed of quality (such as rubber, etc.). For Axle = L, the head is equipped with a T sleeve bottom two (that is, the axis 60 is near the top end) with 81 this end is fixed to the shaft portion 811, and the collar can be attached to the sleeve Qiu Jin / Department 2 and the sleeve 81 after installation, this -: knife radius schematic inner hollow tubular body 50 of the same aperture schematic. Another — Xiang Er i :: The design of the groove 622 and the protruding portion 811 is omitted, and is replaced by; 2 (see Figure 8 for the replacement). The form of the axis 60 can be in the form of the middle U figure (Figure 6) or solid (see Figure 9). A slider 82 is connected to the shaft, the other two ends, and the slider 82 can slide relative to = 60. When the buffer rod I is retracted, as shown in "Figure 7A", drive Ϊ 61 to slide the axis 6 ° relative to the hollow tube 50, so that the head 6; However, the slider 82 has a certain rigidity: Only the clothing is connected ', so it will be pulled by the collar 81 to slide, so that 538202

When the inner ring of the collar 81 5 0 is restored, the elasticity of the product is also because the 8 2 stays in motion. The front square makes it deform and stretch for the required deformation and slightly reduces the wall friction, which is helpful to the "Figure 7β" It is shown that by using the energy, the shaft center 60 and the rigidity of the slider 82 can be pushed in place, so that the outer diameter of the collar 81 is slightly expanded by the resistance of the slider 82, and the cushioning resistance is moderate. Its outer diameter reduces compression with the hollow tube's bumper. When the instrument punch returned from the compression before the spring 70, the hollow tube 50 slid outward. When the core 60 just moved outward, the rear of the slider was pushed by the head 62 of the shaft center 60, so The collar 81 is caused to interfere with the inner hole of the compression-emptied pipe body 50. In order to adjust the cushioning resistance of the compression type buffer rod, an adjusting member 83 is added to the damping unit 80, please refer to "第 ι〇 / Figure B ", the adjusting member 83 replaces the head 62 in the embodiment of" Figure 6 ", and the adjusting member 83 is movably fixed to the top end of the shaft center 60.
