Description
Technical field:
The present invention relates to a kind of plain type pressure rod, refer to a kind of buffering effect that reaches especially, and can make this mandrel rod body reach the stable effect that slowly resets, and then can reach the plain type pressure rod that designs simplification, assembling reach the purpose of saving cost fast.
Background technique:
The existing patent No. is M292326, patent name is the buffer structure of closing of slide rail, as shown in Figure 1, when the positioning rod 71 of this slide block 7 is pushed when then moving the fixing mouthfuls 73 of withdrawing from sliding-groove 72, because this slide block 7 loses the solid power of holding of positioning rod 71, be subjected to the restoring force influence of this elasticity tension assembly 74 again, making this slide block 7 to do involution fast backward moves, but the slide bar 84 that connects this resistance to compression buffer 8 simultaneously by these slide block 7 rear ends, and the piston head 85 that can make these slide bar 84 rear ends can be done pusher in the cylinder body 81 and moves, therefore when this slide block 7 when involution is moved backward, its fast back thrust can oppress air in the cylinder body 81 of this resistance to compression buffer 8, make the air in this cylinder body 81 slowly to discharge release along the pressure release breach 851 of piston head 85 rear ends, relaxed front end slide block 7 and moved by the quick involution of elasticity tension assembly 74 restoring forces traction, thereby can be reached the buffering effect;
This slide rail close buffer structure, though it can reach the buffering effect, but its resistance to compression buffer 8 of buffer structure of cutting out because of this slide rail comprises a cylinder body 81, a tail-hood 82, a packing ring 83, a slide bar 84, a piston head 85, a leak-stopping rubber 86, therefore these resistance to compression buffer 8 integrated members are various, cause overall structure very complicated, and then easily cause assembling speed slowly to reach the disappearance of manufacture cost costliness, thereby often by the user dirt sick:
1, resistance to compression buffer integrated member is various.
2, overall structure is very complicated.
3, easily cause assembling speed slowly to reach the disappearance of manufacture cost costliness.
Therefore, how disappearance such as above-mentioned is forgone, be the place of the technical difficulties of this case creator institute desire solution.
Summary of the invention:
Technical problem to be solved by this invention is for a kind of plain type pressure rod being provided, making it can reach designs simplification, assembling and reach the saving cost fast.
The present invention solves the technological scheme that its technical problem takes: a kind of plain type pressure rod, it is characterized in that, and comprise:
One body is provided with room in this body, and this body one end is provided with at least one hole, and this hole and room connect, and this body the other end is provided with second opening again;
One mandrel rod body, this mandrel rod body one end is provided with elastomer, and this elastomer is arranged in the room of body;
One lid, this lid cover are fixed in room one end of body, and are provided with at least one hole in this lid;
For can be in actual applications can the picked at random equipment, described body can replace with fixed base, is provided with room in this fixed base.
After adopting said structure, its advantage is: when this mandrel rod body resets, by being provided with hole in this lid, make the interior air of this room and this air can slowly be discharged by the hole of this lid by the extruding of the elastomer of mandrel rod body, and can reach the buffering effect, and can make this mandrel rod body reach the stable effect that slowly resets, and then can reach designs simplification, assemble quick and save the purpose person of the cost.
