The specific embodiment

Detailed description of relevant the utility model and technology contents, following conjunction with figs. is explained as follows:

Please consult the buffer unit 1 that Fig. 1, Fig. 2, Fig. 3-1～Fig. 3-2 and the drawer sliding rail of the utility model one preferred embodiment shown in Figure 4 are used simultaneously.As shown in the figure, this buffer unit 1 includes one in order to being fixedly arranged on the buffing pad 10 on the object, and one is located at the drive piece 60 on another object with respect to this buffing pad 10; This buffing pad 10 has the disposal area 11 of inserting fender pile 40, and wherein this fender pile 40 has a connecting rod 41; These disposal area 11 1 ends end that stretches out has the guide rail 12 of hooked part 122, and these guide rail 12 both sides respectively have recessed rail 121, and these disposal area 11 other ends then extend respectively and respectively are provided with a pulling piece 50 to both sides; In addition being provided with one in this guide rail 12 joins with this connecting rod 41 and guide block 20 that both sides also join with this pulling piece 50; These guide block 20 belows are extended with the projection 21 that can corresponding be slidably connected to this recessed rail 121; And this guide block 20 articulates a movable block 30; And this movable block 30 has a stop part 31 with the end that this guide block 20 articulates, and the other end then has a hook portion 32 and a following hook portion 33 with respect to the formation of 32 position-reversed of hook portion on this on one, and this time hook portion 33 contacts with this guide rail 12; In addition, but 60 of this drive pieces have that the pushing part 61 and of an ejection to this stop part 31 can make hook portion 32 clasp joints on this hook together groove 62; Wherein, this fender pile 40 can be vapour-pressure type or hydraulic type, and this pulling piece 50 can be extension spring.Hence one can see that, and the utility model is not only simplified the structural design of buffer unit 1, fast easily, also can reach the purpose that reduces manpower and Material Cost thus when making production and assembly, and reduce the market price effectively and meet the demand in market.

In order to make the reader further understand the continuous action of the utility model user mode, please consult simultaneously shown in Fig. 5-1～5-7 so be tired of other.At first ask shown in the 5-1 with the aid of pictures; When following hook portion 33 clasp joints of movable block 30 during in the hooked part 122 of guide rail 12, the pulling piece 50 of this moment has formed the state that is stretched, that is to say; When if this time hook portion 33 breaks away from this hooked part 122; Guide block 20 and this movable block 30 will be by these pulling piece 50 drawings, and can promote connecting rod 41 synchronously and compress fender pile 40, thereby reach the purpose of buffering; So; When drive piece 60 by bestow one left external force and after the displacement; This pushing part 61 that drives piece 60 will be shown in Fig. 5-2 ejection to stop part 31, make this movable block 30 shown in Fig. 5-3, can pivot, and make this time hook portion 33 separate with this hooked part 122 through this guide block 20; Drive under the situation on the piece 60 at this for no external force this moment; The last hook portion 32 of this movable block 30 also can stretch into the hooking together groove 62 of this drive piece 60 and form clasp joint, makes this pulling piece 50 can borrow this guide block 20 of its elastic force drawing make synchronous shift with this movable block 30, and drives this drive piece 60 simultaneously and promote this connecting rod 41 and make synchronous shift shown in Fig. 5-4; Again till the displacement, so promptly reach the purpose that buffering is returned back automatically until shown in Fig. 5-5, finally being obstructed.On the contrary; If when bestowing this drive piece 60 1 reverse (to the right) more in addition this moment and can overcome the external force of these pulling piece 50 elastic force; Then this drive piece 60 can spur this guide block 20 and these movable block 30 synchronous shift; And can drive these connecting rod 41 Shen length synchronously this pulling piece 50 is stretched, pivoting through this guide block 20 until this movable block 30 shown in Fig. 5-6 makes this time hook portion 33 hook together in this hooked part 122 just stopping, and hook portion 32 can hook together groove 62 with this and separated on this this moment; But because it is still lasting underway to bestow this drive piece 60 external force to the right, therefore the pushing part 61 of this drive piece 60 can separate with this stop part 31, and this drive piece 60 can separate shown in Fig. 5-7 with this movable block 30 fully at last.
