When a force is applied to thehandles 2224 on the handle connection block 226 and thelock bolt 222 of onelock bolt structure 22, the handle connection block 226 and thelock bolt 222 move towards each other, so that the handle connection block 226 pulls the handle connection block 226 on the otherlock bolt structure 22 through thesteel wire rope 23, then thelock bolt 222 of the otherlock bolt structure 22 is driven to move accordingly, and thus, twolock bolts 222 move towards each other; After the force is eliminated, the twolock bolts 222 move away from each other under a restoration effect of thesprings 225, that is, thesprings 225 in the twolock bolt structures 22 are synchronously compressed or restored to realize synchronous locking or unlocking. - The carriage is provided with a
carriage sideboard 102. The limit lockingclamp assembly 1 includes afirst clamping plate 11, asecond clamping plate 12, afirst clamping member 13, and asecond clamping member 14, wherein thefirst clamping plate 11 and thesecond clamping plate 12 are respectively fastened on two side faces of thecarriage sideboard 102 through the first clampingmember 13. Thesecond clamping plate 12 is provided with a through hole, and thesecond clamping member 14 penetrates through the through hole and abuts against thefirst clamping plate 11 to fix thefirst clamping plate 11 and thesecond clamping plate 12 in the vertical direction. Thelimit step 121 is located at thesecond clamping plate 12. Thefirst clamping plate 11 and thesecond clamping plate 12 are clamped at thecarriage sideboard 102 through the first clampingmember 13 to form a limit locking clamp to fix positions of thefirst clamping plate 11 and thesecond clamping plate 12 in the horizontal direction, the first clampingmember 13 may be a screw, thefirst clamping plate 11 and thesecond clamping plate 12 are vertically fixed by thesecond clamping member 14, and the perpendicularity of the limit locking clamp is adjusted to make thefirst clamping plate 11 and thesecond clamping plate 12 in a fastened state, so that thefirst clamping plate 11 and thesecond clamping plate 12 will not get loose when the vehicle body shakes during traveling; and thesecond clamping member 14 may be a quincunx screw which is beneficial to subsequent adjustment. -
Anti-slip teeth 123 are disposed at clamping faces of thefirst clamping plate 11 and thesecond clamping plate 12 and the clamping faces are in contact with thecarriage sideboard 102, increasing the friction between thefirst clamping plate 11 and thecarriage sideboard 102 as well as the friction between thesecond clamping plate 12 and thecarriage sideboard 102, so that the limit lockingclamp assembly 1 is not prone to getting loose. - The
carriage sideboard 102 is provided with a firstbent part 1021, the firstbent part 1021 is bent upwards. Thefirst clamping plate 11 is provided with a second bent part, and the second bent part is bent downwards. The firstbent part 1021 is matched with the secondbent part 111 to limit thefirst clamping plate 11 in the vertical direction. When thecarriage cover 101 is clamped into thelimit step 121 through thelock catch assembly 2, a force is applied to the limit lockingclamp assembly 1 in the vertical direction, and the secondbent part 111 hooks the firstbent part 1021, so that the force borne by the limit lockingclamp assembly 1 in the vertical direction is increased. - An arc-shaped
guide face 2225 is disposed at an end of eachlock bolt 222, the end of eachlock bolt 222 is close to thelimit step 121. An arc-shapedstop edge 1211 is disposed at an edge of thelimit step 121, the edge of thelimit step 121 is close to eachlock bolt 222. Theguide face 2225 is matched with thestop edge 1211 to clamp thelock bolt 222 into thelimit step 121. When thecarriage cover 101 is mounted, because the guide faces 2225 on thelock bolts 222 and thestop edge 1211 of thelimit step 121 both are arc-shaped, the arc-shaped guide faces 2225 can partially convert a vertical pressing force generated by pressing thecarriage cover 101 into a horizontal force to promote thelock bolts 222 to move away from thelimit step 121, and then the guide faces 2225 are smoothly clamped into thelimit step 121. When thelock bolts 222 are clamped into thelimit step 121, the contact faces between thelock bolts 222 and thelimit step 121 are planes, so that a contact area is large, thelimit step 121 can be sustained, and the structure is more reliable. - The above embodiments are only preferred ones of the invention, and are not intended to limit the protection scope of the invention. All equivalent structural transformations achieved on the basis of the contents of the specification and accompanying drawings, and direct or indirect applications to other related technical fields should also fall within the protection scope of the invention.
