Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment who obtains, and all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the blast structural representation of the telescopic pipe locking mechanism that Fig. 1 provides for the utility model embodiment; The integral installation distribution structure schematic diagram of the telescopic pipe locking mechanism that Fig. 2 provides for the utility model embodiment; Fig. 3 is the sectional view of Fig. 2; The rear interior component locations figure that sees of telescopic pipe locking mechanism assembling that Fig. 4 provides for the utility model embodiment; The telescopic pipe locking machine that Fig. 5 provides for the utility model embodiment is in the schematic diagram of structure locking state; The torque analysis schematic diagram of the telescopic pipe locking machine that Fig. 6 provides for the utility model embodiment.
The telescopic pipe locking mechanism that the utility model embodiment provides, its core improvement are, comprise locking bed fixed tube 2, locking element 3, bolt 4, locking bed 5, wrench 6, compressing tablet 7 and adjusting nut 8;
One end of bolt 4 is connected in locking element 3, and the other end can pass locking bed 5 with the relative locking sidewall of its cavity, and it stretches out the through hole that screw portion can pass compressing tablet 7 one side locking ends and locks by worm structure with regulating nut 8;
The spanner of wrench 6 has cam structure, can coordinate with the arc groove on the locking sidewall;
Under the state that compressing tablet 7 one side locking ends are locked by bolt 4 and adjusting nut 8, the movable end of compressing tablet 7 opposite sides can be pressed on the cam structure of wrench 6 spanners.
Below in conjunction with the working principle of accompanying drawing to this programme telescopic pipe locking mechanism, be described below:
Refer to Fig. 4 and Fig. 5, when wrench 6, when 1. direction is rotated, under the effect of its spanner cam structure, can order about compressing tablet 7 around 4. along 2. direction, rotating, drive simultaneously adjusting nut 8, bolt 4 and locking element 3 edges 3. direction move; And then locking element 3 drives telescopic pipes 1 and moves towards the C direction, makes two faces of A, B and the clamping of the C face on locking element 3 telescopic pipe 1 on locking bed 5.
Simultaneously, as shown in Figure 6, the contact position of the spanner cam structure of wrench 6 and compressing tablet 7 movable ends is D, and adjusting nut 8 is E with the contact action position of compressing tablet 7 locking ends; F is arranged
1* L
1=F
2* L
2, because arm of force L
1L
2So, directed force F
2F1; Be that compressing tablet 7 has the lever effect, so this structure can improve coupling mechanism force.
In addition, can also regulate coupling mechanism force by adjusting nut 8, the longer coupling mechanism force of distance that screws in bolt 4 screw portions when adjusting nut 8 is larger.
From above-mentioned technological scheme, can find out, the telescopic pipe locking mechanism that the utility model embodiment provides, faster by the wrench locking mode, compressing tablet 7 plays the lever effect, and coupling mechanism force is larger, and adjusting nut 8 can be regulated the coupling mechanism force size.Therefore, the locking mode of this programme telescopic pipe 1 can make locking mode faster in the situation that do not affect product functionality, improves coupling mechanism force, reliability.
