Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
Embodiment, assembles showing stand, as shown in figure 1, including connecting rod 111, two identical connecting rods 111 are at respective center
Hinging rotary is realized by the swivel pin 112 of insertion, and forms a lifting assembly.Three lifter groups 11 are from top to bottom successively
Superposition is set, and the connecting rod 111 of two lifting assemblies is also to be hinged to form a crane 1, Ke Yifa by swivel pin 112
It is existing, it can cause that the overall height of crane 1 increases by pulling out the connecting rod 111 at the two ends of crane 1；And inwardly compress
The connecting rod 111 at the two ends of crane 1 can cause the overall reduced height of crane 1.
Sleeve 4 is fixed in the end of upper and lower arrangement cross bar 22, what the socket of sleeve 4 was arranged in opposite directions, the sleeve of top cross bar 22
4 are inserted with secondary bar 32, and the sleeve 4 of lower section cross bar 22 is inserted with mobile jib 31, and secondary bar 32 inserts mobile jib 31, is inserted by adjusting secondary bar 32
The depth of mobile jib 31 adjusts the height of telescopic component.
The connecting rod 111 at the two ends of crane 1 is provided with axle sleeve 21 by swivel pin 112, the logical set of the circle of axle sleeve 21 and can be around being hinged
Point does circular-rotation.
As shown in Fig. 2 after crane 1 will adjust and arrive suitable height, the cross bar 22 of round bar shape is inserted into axle sleeve 21, axle
There is gap between set 21 and cross bar 22, the damping block 23 of wedge shape is inserted in the gap, damping block 23 inserts axle sleeve by small end
21 and it is fixed on the end of axle sleeve 21.Damping block 23 is made of plastics, when inclined-plane 341 and the plane of damping block 23 are contradicted respectively
Between axle sleeve 21 and cross bar 22, the fixation of cross bar 22 and axle sleeve 21 is realized.And when needing to remove damping block 23, it is only necessary in axle sleeve
21 other end passes through tiny bar top pressure damping block 23 so that damping block 23 depart from the sliding of axle sleeve 21.
As shown in Figure 3 and Figure 4, and the end of mobile jib 31 is fixed with the elastic expansion sleeve 33 of taper, the end of elastic expansion sleeve 33 is opened
Provided with otch 331, otch 331 is rectangular-shaped, and the width of otch 331 is 0.2mm, is completed by wire cutting technology.Otch 331 is circumferentially
Direction is uniformly arranged in elastic expansion sleeve 33.And claw is formed between two adjacent cuts 331, claw is due to the work of otch 331
The oriented inside of elastic expansion sleeve 33 of apparatus and outside mobile elastic deformation ability.And claw is welded with latch 332, latch 332
For triangle bulk and the circle centre position of wedge angle sensing elastic expansion sleeve 33.
Clamp nut 34 is set on elastic expansion sleeve 33, and the outer wall of mobile jib 31 is also externally threaded, and external screw thread is placed in elasticity
The lower section of expansion set 33, clamp nut 34 is threaded on external screw thread.The outer wall of clamp nut 34 offers cave in annular recessed
Groove 342, and the inwall inclined-plane 341 of clamp nut 34, the inclined-plane 341 are the inclination curved surface of taper.
The end of secondary bar 32 is formed with block 35, and the width of block 35 is more than the aperture of circular hole in mobile jib 31, therefore keeps off
Block 35 can be with barrier at the end of mobile jib 31, secondary bar 32 is difficult to be further inserted into inside mobile jib 31, it is to avoid secondary bar 32 is complete
Submerge in mobile jib 31.
Operation principle, mobile jib 31 and the installation of secondary bar 32, insert mobile jib 31 by secondary bar 32, next revolve clamp nut 34
Tightly, axis of the inclined-plane 341 along mobile jib 31 is moved down, the arc that round platform is fitted in round table-like and inclined-plane 341 of elastic expansion sleeve 33
Face, inclined-plane 341 contradicts on claw and further extrudes claw so that claw is fitted in the outer wall of secondary bar 32 and realized to secondary bar 32
Clamping, and now, the frictional force that claw is produced carries out sealed to secondary bar 32.
Mobile jib 31 and the dismounting of secondary bar 32, screw out clamp nut 34 so that elastic expansion sleeve 33 disappears in the external force of radial direction, bullet
Property expansion set 33 reset, claw depart from secondary bar 32, now, therefore mobile jib 31 can be relatively moved with secondary bar 32 so that mobile jib 31 with pair
Bar 32 extracts the sleeve 4 of cross bar 22, then compresses crane 1 so that volume is reduced, and is easy to shipment.
