Embodiment
Referring to Figures 1 and 2, a kind of telescoping support linkage, including one first slide rail 10 and longitudinal sliding motion are arranged on
One second slide rail 20 on one slide rail 10, a locking piece 30 is pivoted with by a horizontal drive-connecting shaft 21 on the second slide rail 20, this
In embodiment, the locking piece 30 includes an interlude and two side segments and is substantially in " Z " font, and drive-connecting shaft 21 is located at interlude
Center, the two side of the interlude of the locking piece 30 is respectively two first guiding faces 31, and the lateral wall of two side segments is distinguished
For two second guiding faces 32, the upper left side of locking piece 30 is provided with one first guiding block 11, and the lower right of locking piece 30 is provided with
One second guiding block 13,13 equal lateral run-out drive-connecting shaft 21 of the first guiding block 11 and the second guiding block, pair of the second guiding block 13
Side is provided with a block 14, and the second guiding block 13 and the block 14 surround a port 12, when locking piece 30 is in transverse state
The port 12 can stop that locking piece 30 passes through, and when locking piece 30 is in longitudinal state, the port 12 is available for locking piece 30 to pass through,
The lower section of port 12 is provided with the guide groove 15 of a longitudinal direction, and the guide groove 15 is located at the rear of port 12 and connected with the port 12, when
Locking piece 30 may pass through port 12 and enter in the guide groove 15 and along the longitudinal sliding motion of guide groove 15 when being in longitudinal state, and when lock
When determining part 30 and being located in the guide groove 15, an at least madial wall for guide groove 15 leans to limit locking piece with the side wall of locking piece 30
30 around its drive-connecting shaft 21 rotation, locking piece 30 can pass through port 12 when moving up the second slide rail 20 after can ensureing,
Ensure the normal use of this support rod mechanism.
Reference picture 3, use flow diagram of the present invention, in a states, locking piece 30 be in transverse state and with block 14
With the second guiding block 13 against, locking piece 30 is stopped by port 12, and the second slide rail 20 can not move down with respect to the first slide rail 10, so as to
This support rod mechanism is locked, the second slide rail 20 can now be moved up, during the second slide rail 20 is moved up, the first guiding block
11 lean with the first guiding face 31 and are slided along the first guiding face 31, so as to promote locking piece 30 to rotate counterclockwise, when
It is in b states when at the top of being moved on the second slide rail 20, locking piece 30 has turned to longitudinal state, afterwards can be by under the second slide rail 20
C states are moved to, now the second guiding block 13 and the first guiding face 31 lean and can move down promotion lock with the second slide rail 20
Tight part continues to rotate counterclockwise an angle so that second guiding face 32 at the top of locking piece 30 can turn to and the first guiding block
11 longitudinally-aligned positions, subsequent locking piece 30 can be slipped into guide groove 15 by port 12 to be in d states, now the first slide rail 10
Longitudinally opposed it can be slided with the second slide rail 20, even if this support rod mechanism can freely stretch；Ordered the second slide rail 20 in d states
When moving up, the first guiding block 11 can be resisted against on the second guiding face 32 and promote locking piece 30 to rotate counterclockwise, when the second slide rail
It is in e states when moving to top on 20, the second slide rail 20 can be moved down afterwards to f states, now the second of the bottom of locking piece 30 is led
Draw the guiding block 13 of face 32 and second against, so as to promote locking piece 30 to rotate counterclockwise to transverse state, that is, return to a states and
Lock this support rod mechanism.So circulation can realize the locking and unblock of this support rod mechanism repeatedly.The present invention it is simple in construction,
It is ingenious, manufacture is readily produced, and meanwhile it is easy to operate, it is easy to use.
Certainly, in actual applications, locking piece 30 can also use parallelogram, circular arc etc. than a circular one other
Anticipate suitable shape, the quantity and arrangement mode of the first guiding face 31 and the second guiding face 32 can also be flexible according to actual conditions
Adjustment, in the present embodiment, the quantity of the first guiding face 31 for two and on the Central Symmetry of drive-connecting shaft 21, the second guiding face 32
Quantity is two and on the Central Symmetry of drive-connecting shaft 21, so just enables locking piece 30 to be led in the first guiding block 11 and second
Draw state of the cycle rotation without manually adjusting locking piece 30 under the promotion of block 13, convenient use, certainly, in practical application
Can be by adjusting the distribution of the first guiding face 31 and the second guiding face 32 and locking piece 30 can be in the first guiding block 11
Swung back and forth under promotion with the second guiding block 13 to reach identical effect.
The second guiding block 13 set up in the present embodiment is used for the angle of adjust automatically locking piece 30 so that is slided second
When rail 20 moves up, the first guiding block 11 can abut with the corresponding guiding face 32 of first guiding face 31 or second, it is possible to increase lock
Determine the stability and reliability of the action of part 30, certainly, can also be substituted in practical application using other structures such as reduction torsion springs
Second guiding block 13 serves the same role, or passes through the first guiding face 31, the second guiding face 32 and the first guiding block 11
Shape and arrangement mode come reach above-mentioned purpose without use the second guiding block 13, likewise, port 12 can also be independent
It is opened on the first slide rail 10 without being surrounded by the guiding block 13 of block 14 and second, it is not limited to this.
The bottom of first slide rail 10 is additionally provided with a limited block 16, and the limited block 16 can offset with the end of the second slide rail 20
By with the distance of the 20 relative longitudinal sliding motion of first slide rail 10 of the second slide rail of limitation, preventing the second slide rail 20 from deviating from the first slide rail 10.
In addition, the first slide rail 10 is in flat drum shape in the present embodiment, the second slide rail 20, which slides, to be plugged in the inner chamber of the first slide rail 10 to incite somebody to action
Second slide rail 20 is slidably arranged on the first slide rail 10, and certainly, in practical application, the first slide rail 10 and the second slide rail 20 can also
Using structures such as conventional expansion links, the second slide rail 20 can also be slidably arranged on the first slide rail 10 by structures such as guide rails.
The preferred embodiments of the present invention are the foregoing is only, as long as realizing the skill of the object of the invention with essentially identical means
Art scheme is belonged within protection scope of the present invention.
