Embodiment

Below in conjunction with the accompanying drawings, the specific embodiment of the utility model ram is described in further detail：

Embodiment

As shown in Fig. 1,2 and 3, ram includes an outer tube 1 and inner tube 2.Outer tube 1 and inner tube 2 by metal tube, As aluminum pipe is processed, shape is rounded, internal diameter of the external diameter of inner tube 2 close to outer tube 1.Installed when inner tube 2 and be socketed in outer tube 1 When on front end, inner tube 2 can be leaned against to slide axially in outer tube 1, and both can mutually stretch.Being provided with outer tube 1 and inner tube 2 can Slide bar 3, the reliable slip in inner tube 2 of leading portion 4 of slide bar 3 in axial sliding, the endpiece 5 of slide bar 3 is reliable to be slided in outer tube 1. Provided with spring 6 is hit in outer tube 1, hitting spring 6 and can suppressing makes it outwards eject on slide bar 3, and inner tube 2 is provided with cinclides 7, wall Ball 8 is provided with hole 7, the protrusion sphere that ball 8 exposes cinclides 7 can be kept off on leading portion 4, the internal face 9 of outer tube 1 is provided with least The rearward recess 12 that ball 8 protrudes sphere can be accommodated.Between the leading portion 4 and endpiece 5 of slide bar 3 between one section of medial surface to inner tube 2 For a passage 10 for being more than protrusion sphere.

When slide bar 3 is constantly moved to the tail end of outer tube 1, hitting spring 6 can then be gradually compressed, and now, can produce slide bar 3 Raw elastic force forward.

Four cinclides 7 are symmetrically arranged with the tube wall of inner tube 2, cinclides 7 has certain depth.Placed in each cinclides 7 One ball 8, the diameter of ball 8 is more than the wall thickness of inner tube 2.So, ball 8 just have one protrusion sphere expose cinclides 7.

When the position of internal face 9 that cinclides 7 is in outer tube 1 is slided, the outside of ball 8 can be withstood on internal face 9, make ball 8 Protrusion sphere be in the inner side of inner tube 2, now four balls 8 just have four protrusion spherical symmetries protrusions, and keep off in cunning On the front end face of the leading portion 4 of bar 3, make slide bar 3 is relative in inner tube 2 to be positioned.Inner tube 2 is pressed, is also equivalent to be that pressing is slided Bar 3.

When cinclides 7 moves to 12 position of rearward recess, ball 8 is in the presence of the elastic force of spring 6 is hit, the edge in cinclides 7 Radially outward roll, and quickly fall into rearward recess 12, now, the original protrusion sphere of ball 8 is in the internal face of inner tube 2 Within so that the front end face moment of slide bar 3, which loses, keeps out, and slide bar 3 slips over then quick after the protrusion sphere of ball 8 in passage 10 Outwards ejected, gear can be smashed in glass 24 above.The shock elastic force of spring 6 is bigger, and impact is also bigger, hits spring 6 That is compressed is more, and impact also can be bigger.

Before use, making the leading portion 4 of slide bar 3 be in behind ball 8 first.Then by inner tube 2 to pusher, make outside its retraction In pipe 1, now, ball 8 will be moved with inner tube 2.Because the outside of ball 8 is withstood on internal face 9, therefore ball 8 is interior There is a protrusion sphere inside that side is maintained at inner tube 2, and keeps gear on the front end face of slide bar 3, makes slide bar 3 also with inner tube 2 Move backward together.Hitting spring 6 will be limited and be gradually compressed by the tail end of the tail end of inner tube 2 and outer tube 1, gradually put aside Energy.

Continue inner tube 2 to pusher, until ball 8 in outer tube 1 when moving to 12 position of rearward recess, now, ball 8 by In the dependence for losing the internal face 9 of outer tube 1, it can fall into rearward recess 12.The front end face of slide bar 3 loses keeping out for ball 8, Ejected forward rapidly under the elastic force of shock spring 6 effect compressed.The leading portion 4 of slide bar 3 crosses ball 8 first, launches forward, because This can be used for impacting object.

The internal face 9 of outer tube 1, which is provided with, can at least accommodate the forward recess 11 that the protrusion sphere of ball 8 is fallen into, and forward recess 11 is with after Provided with a distance of stretch out and draw back S between groove 12.The inner side of forward recess 11 is provided with inclined-plane 25, the i.e. trapezoidal shape in the section of forward recess 11.When Ball 8 is touched to be easy to roll out forward recess 11 along inclined-plane 25 behind inclined-plane 25.

After slide bar 3 goes out shock, outer tube 1 is picked up upwards, or thing such as glass 24 will be hit and is removed, inner tube 2 will be downward Fall or protruding, outer tube 1 and inner tube 2 will trail.When inner tube 2 launched since release to expansion one apart from S, you can Ball 8 is set to move in forward recess 11, in this manner it is possible to which in the position of forward recess 11, the leading portion 4 of slide bar 3 is moved into ball 8 Below, then compress outer tube 1 and inner tube 2, ball 8 exits forward recess 11 in the case where the cinclides 7 of inner tube 2 is extruded, and keeps out preceding On the front end face of section 4, in case compression impact again.Although forward recess 11 and rearward recess 12 can be such that ball 8 falls into groove, by When position of the ball 8 in forward recess 11, hit spring 6 and be in relaxed state.Ball 8 hits at the position of rearward recess 12 Spring 6 is in confined state.Therefore, in the position of forward recess 11 than being easier to fall into ball 8 in the position of rearward recess 12 In groove.As long as in use, outer tube 1 and inner tube 2 are extended into ball 8 is in the position of forward recess 11, so that it may so that ball 8 is easily Ground is placed in the front end face of leading portion 4, convenient compression.

Inner tube 2 is provided with blocking surface 14, and leading portion 4 is provided with striker 13, and blocking surface 14, which is provided with, can hold what striker 13 was passed through Pin hole 15, is provided with (the first back-moving spring 16 between blocking surface 14 and leading portion 4.

The effect of (the first back-moving spring 16 is exactly inner tube 2 is separated with slide bar 3, i.e., make inner tube 2 as illustrated in the drawing Move downward or overhang, slide bar 3 is moved upwards.Due to inner tube 2 and the quality of slide bar 3 all very littles, therefore (the first back-moving spring 16 elastic force is as small as possible, as long as making inner tube 2 and slide bar 3 to be trailed in outer tube 1.

After shock, leading portion 4 is in the anterior locations of ball 8.When outer tube 1 is picked up upwards, or thing such as glass will be hit Glass 24 is removed, and (the first back-moving spring 16 can be withstood between blocking surface 14 and the leading portion 4 of slide bar 3, slide bar 3 is stretched with inner tube 2, preceding Section 4 is then moved from the direction of trend ball 8.When ball 8 is in 11 position of forward recess, due to the elastic force pressure of (the first back-moving spring 16 Effect, ball 8 can automatically fall into forward recess 11, and leading portion 4 can be then retreated to behind ball 8.

When inner tube 2 is inwardly moved, ball 8 is recessed before being left under the common extruding of the edge of forward recess 11 and cinclides 7 Groove 11, and keep off on the front end face of leading portion 4, in case next time, pressing was hit.

Leading portion 4 is provided with striker 13, so, is manufactured using aluminium, leading portion 4, the weight of endpiece 5 can be made significantly to mitigate, again It is easy to processing.And the small volume of striker 13, steel alloy, or the high material manufacture of hardness can be used, by being a tight fit on leading portion 4 Hole in it is fixed.This allows for the entirety of slide bar 3 lightly, and rum point is then hard.Striker 13, which is ramped up, passes forward pin hole 15 Strike on glass, glass fragmentation at once can be made.

Suppressed between inner tube 2 and slide bar 3 and be provided with second back-moving spring 17.Second back-moving spring 17 can make inner tube 2 with sliding It is provided between bar 3.

After shock, second back-moving spring 17 can make inner tube 2 travel forward, and (the first back-moving spring 16 can make slide bar 3 Move backward, by the active force being applied on leading portion 4 and the active force for being applied to ball 8, both reversely pull, then ball 8 It can automatically fall into forward recess 11.The elastic force of second back-moving spring 17 is set without too big as long as can flick inner tube 2 to required Fixed distance.

Endpiece 5 is provided with movable loop 18, and slide bar 3, which is provided with, can keep out the stopper 19 in the outside of movable loop 18, hits Spring 6 and second back-moving spring 17 are suppressed at the two ends of movable loop 18 respectively.

Movable loop 18 is enclosed on slide bar 3 in annular shape, and its outside is leaned against on the internal face of outer tube 1, and can be slided vertically It is dynamic.

Hit spring 6 to suppress on movable loop 18, its elastic force is applied on slide bar 3 by stopper 19, makes slide bar 3 all the time By from the elastic force for hitting the application of spring 6.And second back-moving spring 17 is suppressed in inner tube 2 and movable loop 18, it is only By inner tube 2, outwards top is opened, and is to hit the endpoint location of spring 6 as basic point.After hitting, spring 6 is hit complete Flick, second back-moving spring 17 is suppressed in inner tube 2, flex outward out inner tube 2, so, the ball 8 in inner tube 2 can be driven Moved to the direction of forward recess 11 of outer tube 1.When ball 8 is moved at forward recess 11, ball 8 will be fallen into forward recess 11, be Leading portion 4 concedes a space in inner tube 2, and (the first back-moving spring 16 can make leading portion 4 pass through the place of ball 8 in inner tube 2 Position, and move to behind ball 8.Now, once inside extruding inner tube 2, ball 8 will jump out forward recess 11, ball 8 Protrusion sphere will keep out in the front end of leading portion 4.

Outer tube 1 is provided with limiting section 20, and inner tube 2 is provided with that can keep out the step 21 on limiting section 20, and limiting section 20 is supported When gear is on step 21, the ball 8 in inner tube 2, which is in, can fall into the position of forward recess 11.

Limiting section 20 is an anchor ring for being arranged on the front end of outer tube 1, and its one side can prevent inner tube 2 from the front end of outer tube 1 Abjection, on the other hand ball 8 can be positioned, i.e., second back-moving spring 17 by inner tube 2 from front end eject to the end when, can To ensure that ball 8 is on the position of forward recess 11.Therefore, as long as ensureing that second back-moving spring 17 has enough length, energy Inner tube 2 is ejected to the end.

When present segment 4 is in 8 anterior locations of ball, because ball 8 has protrusion sphere protrusion in the inner side of inner tube 2, gear exists Behind leading portion 4 so that (the first back-moving spring 16, which is gradually flicked from compressive state to first length, stops.Now movable loop 18 By upward jack-up under the elastic force effect of second back-moving spring 17, as shown in Figure 9, a distance is separated between stopper 19.

What Fig. 3~9 showed expression is working state figure of the ram in each node, is illustrated with reference to each state diagram Its operation principle hit and resetted automatically when pressing is used.
