Description
Technical field
The utility model relates to the telescopic structure, relates in particular to the shrinking structure of suspender pin.
Background technique
Adopting groove-pin structure need change an angle when cylinder type suspender pin is flexible could locking position.The suspender placement of foot causes dislocation before and after flexible like this.Guaranteeing that the suspender pin can both lift by crane in high and low position acquires a certain degree of difficulty.
The model utility content
The purpose of the utility model is to provide the shrinking structure of shrinking structure and suspender pin, and it can guarantee before and after flexible, not misplace.
For realizing the shrinking structure of said purpose, comprise interior pipe, outer tube, interior pipe is inserted in the outer tube and can relatively moves, and is characterized in, also comprises locking structure; Be formed with axial chute on the outer tube, be formed with guide finger on the interior pipe, guide finger is inserted in the chute and forms sliding pair with chute; Locking structure comprises the mobile plate that is positioned at the outer tube outside, and locked groove is arranged on the mobile plate, and the pin on the interior pipe is inserted in the locked groove so that interior pipe, outer tube locking.
Described shrinking structure, wherein, the said pin that is inserted on the locked groove is the said guide finger of the upper end of interior pipe.
Described shrinking structure, wherein, the said pin that is inserted on the locked groove is the load pin of the lower end of interior pipe.
Described shrinking structure, wherein, interior pipe, outer tube are cylindrical tube, and said locking structure is circular hoop, and said mobile plate is half part of hoop.
Described shrinking structure, wherein, interior pipe, outer tube are rectangular tube, and said locking structure is a rectangular hoops, and said mobile plate is half part of hoop.
Described shrinking structure, wherein, side all has said sliding pair around interior pipe, the outer tube, and said mobile plate is the slide plate that is arranged on the outer tube outside.
Described shrinking structure, wherein, all there is said sliding pair the two opposite sides of interior pipe, outer tube, and said mobile plate is the slide plate that is arranged on the outer tube outside.
Described shrinking structure, wherein, interior pipe is a special pipe, outer tube is a special pipe.
Described shrinking structure, wherein, the front end of interior pipe has positioning hole.
Shrinking structure for the suspender pin of realizing said purpose adopts arbitrary aforesaid shrinking structure.
Adopt the sliding pair of chute-guide finger that shrinking structure is consistent before and after flexible, and then lock, can guarantee before and after flexible, not misplace, guaranteed that promptly suspender can both lift by crane in high and low position through locking structure in the outer tube outside.
Description of drawings
Fig. 1 is the schematic representation that first embodiment of the shrinking structure of suspender pin is positioned at suspension centre.
Fig. 2 is that first embodiment of the shrinking structure of suspender pin is positioned at the schematic representation of suspension centre down.
Embodiment
As depicted in figs. 1 and 2, the shrinking structure of suspender pin comprises outer tube 11, interior pipe 12 and hoop 13.One side of outer tube 11 offers axial slide 110, and corresponding axial slide 110, interior pipe 12 have the radially outstanding guide finger 120 that is provided with, and guide finger 120 is plugged in the chute 110.As shown in Figure 2; The lower end of interior pipe 12 is connected with hangs pin 122, receives downward loading force during operation, and the lower end circumferencial direction of interior pipe 12 is evenly equipped with three load pins 121; Corresponding three load pins 121; The lower end flange of outer tube 11 forms jagged, and is formed with three short grooves on the pipe shaft, passes for the load pin of interior pipe.The inboard of hoop 13 is formed with locked groove 130, inserts for guide finger 120 or load pin 121.In Fig. 1, embodiment shown in Figure 2, outer tube 11, interior pipe 12 are cylindrical.
As shown in Figure 1; When the shrinking structure of suspender pin is positioned at suspension centre; Three load pins 121 of interior pipe 12 lower ends are crossed the breach of 11 times end flange of outer tube and are plugged in the short groove on the pipe shaft; The load pin 121 that hoop 13 is encircled outer tube 11 and interior pipe 12 is inserted in the locked groove 130 of hoop 13, therefore inner and outer pipe 12,11 is pinned.
As shown in Figure 2, when the shrinking structure of suspender pin was positioned at suspension centre, the guide finger 120 that hoop 13 is encircled outer tube 11 and interior pipe 12 was inserted in the locked groove 130 of hoop 13, therefore inner and outer pipe 12,11 was pinned.
In the previous embodiment, inner and outer pipe 12,11 is also replaceable to be rectangular tube, and correspondingly, hoop replaces with the rectangle pipe collar.And at locking inner and outer pipe 12,11 o'clock, the translation rectangular hoops is so that sell 121,120 and import in the locked groove 130.
In the previous embodiment, the groove of inner and outer pipe 12,11, pin guide structure are increased to fourth officer by a pair; For example be provided with the sliding pair of chute 110, guide finger 120 in the side in the four directions of inner and outer pipe 12,11, can increase the balance quality of lifting like this, hoop replaces with slide board type and pins structure; Slide board type pins structure example and in four sides of a surrounding tube slide plate is set all in this way; Locked groove is arranged on the slide plate, after inner and outer pipe 12,11 flexible the putting in place, moving slide board; So that the pin on the interior pipe imports the locked groove on the slide plate into, thereby inner and outer pipe 12,11 is pinned.
In the previous embodiment, inner and outer pipe 12,11 can be the telescopic pipe of Any shape, for example is special pipe, just will on the side of outer tube, slide plate be set, and is formed with locked groove on the slide plate, so can inner and outer pipe 12,11 be pinned according to aforementioned manner.
The front end of interior pipe 12 not only can be used for bearing load for hanging pin, can also use as the location.
