And rear lock crook plate guiding incline 524 is tilted to the right 45 °.
It refers to Fig. 3 and vehicle shown in Fig. 3 is essentially applicant in background technique above combined with Figure 1 and Figure 2,
The vehicle with dilatation function of the exhibition vehicle scope referred in column, for details, reference can be made to CN103754150B.It is shown in FIG. 3
Fixed carriage body 7(fixation carriage body 7 is essentially compartment), a dilatation carriage body 8 for being located at the left side of fixed carriage body 7 is shown,
Further it is shown that being located at a dilatation carriage body 8 on the right side of fixed carriage body 7.Due to include in the above description it is upper and lower,
Left and right, front and rear directionality concept, thus can determine that the concept of these directionality is the left side illustrated with Fig. 3 accordingly
For one dilatation carriage body 8, the same example of description below.
When dilatation carriage body 8 to be made removes fixed carriage body 7, forward and backward lock crook plate 51,52 and lock hook seat 3 need to be first released from
Locking relation, specifically: lock crook plate locking and the acting cylinder 61 of the structural system of solution lock control mechanism 6 work, acting cylinder 611
It is stretched to outside cylinder body, drives lock crook plate by 611 induced effect cylinder column connector 62 of acting cylinder and by acting cylinder connector 62
Pin shaft 63 is acted on, lock crook plate effect pin shaft 63 is made to follow hub setting seat front side board sliding slot 421, front baffle sliding slot 441, rear bulkhead sliding slot
451 and hub setting seat back side panel sliding slot 431 to left dislocation (to the left slide) and to preceding lock crook plate presser feet 511 and rear lock crook plate pressure
The left end of the compressing of foot 521, forward and backward lock crook plate 51,52 has a down dip, and rear end upwarps, and makes preceding lock crook plate hook groove 512 and rear latch hook
Plate hook slot 522 leaves lock hook seat 3, the elongation of forward and backward lock crook plate tension spring 54,55 and energy storage at this time.When relieving forward and backward lock crook plate
51,52 dilatation carriage body 8 can be flexed outward towards away from the direction of fixed carriage body 7 with after the sealed relationship of lock hook seat 3.Due to
The relevant apparatus that dilatation carriage body 8 stretches to outside fixed carriage body 7 and return fixed carriage body 7 is belonged into the prior art, such as can be joined
See the patent documents such as CN103754150B and the CN106428252B that applicant refers in background technique column above, thus
It repeats no more.
When dilatation carriage body 8 returns to fixed carriage body 7 and vehicle is made to be in travelable state, then will by the utility model
Dilatation carriage body 8 and fixed carriage body 7 lock, specifically: under the work of acting cylinder 61, induced effect cylinder column 611 is to cylinder body direction
Displacement drives lock crook plate to act on pin shaft by 611 induced effect cylinder column connector 62 of acting cylinder and by acting cylinder connector 62
63 slide to the right, while releasing the compressing to forward and backward lock crook plate presser feet 511,521, at this time in forward and backward lock crook plate tension spring 54,55
Restoring force effect it is lower and make forward and backward lock crook plate under the light right heavy center of gravity effect in a left side for forward and backward lock crook plate 51,52 itself
51,52 right end falls, and forward and backward lock crook plate locked groove 512,522 hooks together on lock hook seat 3 at this time, in vehicle travel process i.e.
Make to encounter jolt, emergency brake, the situation of turn etc, dilatation carriage body 8 will not be thrown out of fixed carriage body 7, can faithfully embody
The technical effect that applicant records in technical effect column above.Further, since carriage body 7 is fixed in being located at for illustrating in Fig. 3
As hereinbefore with the principle to unlock, that is only said is contrary for the locking of one dilatation carriage body 8 on right side, thus
Applicant equally repeats no more.In addition, the utility model is equally applicable to the vehicle similar to CN10642825B structure.
In conclusion technical solution provided by the utility model compensates for the shortcoming in prior art, favorably accomplish
Invention task has faithfully fulfilled the technical effect that applicant refers in technical effect column above.
