Description
Technical field
The present invention relates to a kind of device that bar is carried out to length adjusting, is specifically a kind of height with telescopic pipeline adjusting deviceBranch machine.
Background technology
On the branches of tall trees machine of prior art, be equipped with telescopic pipeline adjusting device, described telescopic pipeline adjusting device comprises two handsRotation set pipe and two telescoping tubes that are slidably matched, it is on telescoping tube that two described hand-screw sleeve pipes are enclosed within respectively two; DescribedOne of them in two hand-screw sleeve pipes is provided with multi-disc blade, the another one in described two hand-screw sleeve pipes be provided with forCompress multi-disc blade so that the interior projection of its contraction; Two described hand-screw casing threads connect. When use, by two hand-screwsSleeve pipe screws, and makes interior projection press multi-disc blade and props up the body of rod to prevent two telescoping tubes generation relative slidings. But above-mentionedStructure has the following disadvantages: above-mentioned two hand-screw sleeve pipes only utilize screw thread to screw realization, and therefore its power that can bear is limited, itsWhile being applied on the heavier branches of tall trees machine of weight, easily make two telescoping tubes produce slip, thereby cause the generation of security incident.Meanwhile, due to the effective locking lacking two hand-screw sleeve pipes, easily there is rotation relatively in two hand-screw sleeve pipes therefore, thereby makeObtain extension adjustment device loosening, and then security incident occurs, make the work of the telescopic pipeline adjusting device of prior art branches of tall trees machineMake reliability lower.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of and can ensure that telescoping tube is difficult for producing the branches of tall trees machine of relative sliding.
Technical scheme of the present invention is, a kind of branches of tall trees machine is provided, and comprises telescopic pipeline adjusting device, and described telescopic pipeline is adjustedRegulating device comprises fixing hand-screw sleeve pipe, movable hand rotation set pipe and two telescoping tubes that are slidably matched, described fixing hand-screw coverIt is on telescoping tube that pipe, movable hand rotation set pipe are enclosed within respectively two; Described fixing hand-screw sleeve pipe is fixedly mounted on a telescoping tubeOn; Described fixing hand-screw sleeve pipe is provided with multi-disc blade, and described movable hand rotation set pipe is provided with for compressing multi-disc bladeSo that the interior projection of its contraction; Described fixing hand-screw sleeve pipe is connected with movable hand rotation set gas thread; Described fixing hand-screw coverOn pipe and movable hand rotation set pipe, be also provided with locking and releasing device.
Described locking and releasing device comprise push button, elastic component and are located in fixing hand-screw sleeve pipe and accommodating push button and elasticityThe cavity of part; A part for described push button is arranged in cavity, and another part of described push button is arranged on outside cavity; DescribedPush button is slidably fitted in cavity; One end of described elastic component is connected with the rear end of push button, the other end of described elastic component and chamberBody inwall connects; The deformation direction of described elastic component is identical with the glide direction of push button; It is one spacing that the front end of described push button is provided withTooth, described movable hand rotation set pipe is provided with the stopper slot matching with limiting tooth.
Described limiting tooth is unidirectional tooth, and described stopper slot is the unidirectional groove matching with unidirectional tooth size shape.
Described unidirectional tooth is provided with that an inclined-plane, is faced directly and an end face, and a side of described end face is connected with inclined-plane, described inThe opposite side of end face is connected with facing directly; Described facing directly is vertical with end face; The angle on described end face and inclined-plane is greater than 0 ° and littleIn 90 °.
Adopt after above structure, the present invention compared with prior art, has the following advantages:
On the fixing hand-screw sleeve pipe of the telescopic pipeline adjusting device of branches of tall trees machine of the present invention and movable hand rotation set pipe, be also provided with locking andReleasing device, can effectively limit the phase contraposition of fixing hand-screw sleeve pipe and movable hand rotation set pipe by this locking and releasing devicePut, the power that can bear to increase it, when it is applied on the branches of tall trees machine that weight is larger, is difficult for making two telescoping tubes to produce slidingMoving, thus the generation of security incident avoided. While the more important thing is locking, must pin push button another hand-screw with a hand backwardTwist lock is tight, prevent user in use a hand pin machine switch trigger another hand rotary locking cover and can unclamp, fromAnd make machine in use because wrong operation causes the loosening potential safety hazard that produces of machine when start telescoping tube. Meanwhile,Due to two hand-screw sleeve pipes are locked, therefore two hand-screw sleeve pipes are difficult for occurring rotation relatively, thereby make flexible tuneRegulating device maintains static, and then avoids occurring security incident, makes the functional reliability of branches of tall trees machine of the present invention higher.
As improvement, described limiting tooth is unidirectional tooth, and described stopper slot is the unidirectional groove matching with unidirectional tooth size shape.The use of this unidirectional tooth and unidirectional groove only makes in the time being tightened hand-screw sleeve pipe and movable hand rotation set pipe can Self-bouncing,In the time unscrewing fixing hand-screw sleeve pipe and movable hand rotation set pipe, play position-limiting action, can revolve and can only manually stir push buttonPine, thus further prevent that two hand-screw sleeve pipes from producing relative rotation, and therefore increased the functional reliability of branches of tall trees machine of the present invention.
