Specific embodiment

In order to illustrate more clearly of the utility model embodiment and technical solution in the prior art, attached drawing will be compareed below Illustrate specific embodiment of the present utility model.It should be evident that the accompanying drawings in the following description is only the one of the utility model A little embodiments for those of ordinary skill in the art without creative efforts, can also be according to these Attached drawing obtains other attached drawings, and obtains other embodiments.In addition, it is opposite between only indicating each component to be related to belonging to for orientation Positional relationship, rather than absolute positional relation.

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4.The utility model is a kind of electric push-pull device, including cabinet 1, upper hook plate 2, Lower hook plate 3, linkage spring 4, driving device 5, trailer 6, the cabinet 1 and described lower 3 one end of hook plate are affixed, the lower hook plate 3 It abuts, can be moved on linkage 4 axial direction of spring with the linkage spring 4, the upper hook plate 2 and the driving device 5 are solid It connects, the driving device 4 is fixed in trailer 6, and to push upper hook plate 2 to realize, upper hook plate 2 closes and makes with lower hook plate 3 hook Hook plate 2 oppresses cabinet 1 and generates the separation that piston structure shell 8 and core 7 are realized in rebound.

Driving device 5 can be electric pushrod.

Lower hook plate 3 is fixedly connected with 8 component of shell using bolt arrangement, 7 component of lower hook plate 3 and electric pushrod and core It is fixedly connected.During pulling in, electric pushrod stretches out first links together hook plate 2 and lower hook plate 3, then by electronic The retraction of push rod pulls core 7 to enter shell 8, overcomes core assembly movement in whole process by the pulling force of electric pushrod Frictional force.In push, hook plate 2 makes it withstand shell 8 in movement, continues to promote by electric pushrod, ejects core 7, Complete push.

During pulling in, upper hook plate 2 is moved to the left under the action of electric pushrod, upper 2 head of hook plate push lower hook plate 3 to Lower movement, when upper hook plate 2 moves to a certain extent, lower hook plate 3 floats upwards under the action of linking spring 5, makes hook plate 2 It is linked together with lower hook plate 3, links state as shown in Fig. 2, pulling upper hook plate 2 by electric pushrod at this time, drive 7 groups of core Part enters 8 component of shell, overcomes the frictional force of cooperation, realizes the effect that hook plate pulls in.

In push, in a state of fig. 2, continue to be moved to the left upper hook plate 2 using electric pushrod, lower hook plate 3 is held Continuous decline, until cabinet 1 is ordered on upper 2 head of hook plate.Continue that electric pushrod is driven to push upper hook plate 2, in this way under reaction force Core 7 starts to progressively disengage shell 8.Realize the effect released.Wherein in push, lower hook plate 3 is due to moving down width Spend larger, hanging buckle 11 overcomes the spring force of both sides pull rod to link together with deck 12 during moving down, and makes lower hook plate 3 It is fixed on low level, in this case, after push completion, upper hook plate 2 can move out lower hook plate 3 with no obstacle Workspace guarantees that push-and-pull process is gone on smoothly next time.

Lower hook plate 3 with linkage spring 4 abuts, when upper and lower hook plate not in contact with when, linkage spring 4 provide support force and The gravity of lower hook plate 3 itself reaches a balance.When upper hook plate 2 and lower hook plate 3 hook merge and lower hook plate 3 electric pushrod work When continuing mobile to 1 direction of cabinet under, linkage spring 4 is under pressure compression, and lower hook plate 3 reaches a lower position therewith It sets.

Can be seen that spring 10 at this time according to Fig. 3, Fig. 4 will be squeezed generation elastic force, so that hanging buckle 11 and deck 12 Between abutting it is closer.

The inner surface of sliding slot 60 be it is relatively smooth, can reduce in this way hook plate 2 and lower hook plate 3 be detached from trailer with The position of friction between sliding slot, stop part 61 is arranged by the size of core 7 and shell 8.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard To belong to the protection scope of the utility model.
