The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of flexible lockable mechanism of pull rod, including two steel columns, two steel column seats, a spring, an outside link set, limit
Bit slice and two steel column keys, two steel column seats are back-to-back snap together after be inserted into draw-in bar lower end in, each steel column seat
Be equipped with the slot laterally penetrated for steel column, the draw-in bar with through-hole, a steel column pair are equipped on slot corresponding position
A steel column seat is answered, the through-hole that each steel column passes through the draw-in bar of corresponding side is mounted on corresponding steel column seat, the spring
In the slot of two steel column seats, left and right ends are connect with a steel column respectively；
The draw-in bar is sleeved in outside link, and the outside link set is sleeved on outside the outside link, two steel column keys
It is mounted on the outside link to put on, outside link is equipped with limit hole, each steel column on position corresponding with each steel column key
It is pierced by outside link corresponding limit hole in lockup state and is in contact with corresponding steel column key；
The limit film is located at the top of the steel column seat and is mounted on outside draw-in bar by limiting film perforation, the limit
Piece can be withstood on during draw-in bar above mentions on the outside link set, so that limitation above proposes movement.
Further, there are two the limit film settings, two limit films are arranged symmetrically on the outer wall two sides of draw-in bar.
The beneficial effects of the utility model are mainly manifested in: structure is simple and convenient to operate.
Detailed description of the invention
Fig. 1 is the perspective view of the explosion of the utility model.
Fig. 2 is the utility model lockup state schematic diagram.
Fig. 3 is the utility model unlocked state schematic diagram.
Fig. 4 is the utility model contraction state schematic diagram.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
Referring to Fig.1~Fig. 4, a kind of flexible lockable mechanism of pull rod, including two springs of steel column seat 6, one of steel column 4, two
3, outside link set 5, limit film 2 and two steel column keys 7, two steel column seats 6 are back-to-back snap together after be inserted into draw
In the lower end of bar 1, each steel column seat 6 is equipped with the slot laterally penetrated for steel column 4, and the draw-in bar 1 is corresponding with slot
Position is equipped with through-hole, the corresponding steel column seat 6 of a steel column 4, and each steel column 4 passes through the through-hole of the draw-in bar 1 of corresponding side
Be mounted on corresponding steel column seat 6, the spring 3 is located in the slot of two steel column seats 6, left and right ends respectively with a steel
Column 4 connects；
The draw-in bar 1 is sleeved in outside link 8, and the outside link set 5 is sleeved on outside the outside link 8, two steel columns
Key 7 is mounted on the outside link set 5, and outside link 8 is equipped with limit hole on position corresponding with each steel column key 7,
Each steel column 4 is pierced by outside link 8 corresponding limit hole in lockup state and is in contact with corresponding steel column key 7；
The limit film 2 is located at the top of the steel column seat 6 and is mounted on outside draw-in bar 1 by limiting film perforation, described
Limit film 2 can be withstood on during draw-in bar 1 above mentions on the outside link set 5, so that limitation above proposes movement.Limit film 2 be
When mentioning on draw-in bar, the device for extracting draw-in bar 1 from outside link 8 that overexerts is avoided.Have since spring 3 ejects steel column 4
A process time, when overexerting, steel column 4 may miss hole, therefore can make above to propose fortune behind the top of limit film 2 to outside link set
It is dynamic to stop, so that steel column 4 be allow to penetrate in hole.
Further, there are two the settings of limit film 2, two limit films 2 are arranged symmetrically in the outer wall two sides of draw-in bar 1
On.
As depicted in figs. 1 and 2, the slot on steel column seat 6 includes spring mounting groove for placing spring and for steel column 4
The circular hole penetrated, the through-hole on draw-in bar 1, the limit hole on outside link 8 are circular hole；Two steel columns 3 are respectively penetrated two
In the circular hole of steel column seat 6, and two steel column seats are fastened after being put into spring 3 between two steel columns.Fastened two steel column seats 6 are inserted into
The bottom of draw-in bar 1 is pierced by two steel columns 4 from the circular hole on draw-in bar 1.By two limit films 2 respectively by draw-in bar 1
Mounting hole, be set on draw-in bar 1.The draw-in bar 1 assembled is inserted into outside link 8, passes through steel column 4 on outside link 8
Circular hole is limited, the movement of outer tie rod 8 is limited.The outside link set 5 for being loaded into two steel column keys 7 penetrates draw-in bar 1 and consolidates
It is scheduled on outside link 8, keeps two steel column keys 7 just coaxial with two steel columns 4.
The working principle of the utility model are as follows: when releasing locking, while pressing two steel column keys 7, press two steel columns 4
Make its compressed spring 3, so that the limit hole for exiting steel column 4 on outside link 8 is as shown in Figure 3.It can at this point, pushing draw-in bar 1
It drives in each component retraction outside link 8 thereon, as shown in Figure 4.When needing locking, it is lifted up draw-in bar 1, makes two limits
On the top to outside link 8 of piece 2 on the inside of the upper end of fixed outside link set 5, to prevent lifting for draw-in bar；Two steel columns simultaneously
The position of the limit hole on outside link 8 is reached, and is penetrated in limit hole under the action of the spring, position-limiting action, such as Fig. 2 are played
It is shown.
