Double gear rack auto -lock ware, include swing joint's landing leg and support main part each other, locking body and adjustment mechanism, adjustment mechanism sets up at the landing leg and supports between the main part, adjustment mechanism is including setting up the rack on supporting the main part, moving part with landing leg swing joint, the moving part through the connecting piece be connected with with first gear and second gear, first gear and the meshing of the 2nd wheel and rack set up, locking body and adjustment mechanism are connected, the manpower make locking body can control the distance between first gear and the second gear under being intervene, and can make win gear and the 2nd gear engagement, because first gear, intermeshing between second gear and the rack has realized adjustment mechanism's lock and has died. Problem through above -mentioned technical scheme, among alright the fine solution prior art.
Description
Technical field
This utility model belongs to self-locking device technical field, is specifically related to double-rack-and-pinion self-locking device.
Background technology
A kind of supporting leg and the hinged structure of supportive body all can be there is, by regulating the angle between supporting leg and supportive body, it is achieved the adjustment to supportive body height in much common field.Such as traditional Extensible belt conveyor.Which floor traditional Extensible belt conveyor be superimposed for, track one skate, vertical leg one skate, using rotating threaded shaft lifting landing leg, this structure is not compact, carries out locking being inconvenient for after determining supportive body height yet, and easily break down, cause locking not dead situation.
Utility model content
The purpose of this utility model is in that to provide double-rack-and-pinion self-locking device, have can fast self-locking, convenient operation, and be not easy to break down.
nullDouble-rack-and-pinion self-locking device，Including the supporting leg being flexibly connected each other and supportive body，Angle between supporting leg and supportive body can be regulated，Also include locking mechanism and governor motion，Described governor motion is arranged between supporting leg and supportive body，The angle between supporting leg and supportive body can be changed very easily by the adjustment of governor motion，Described governor motion includes the tooth bar being arranged on supportive body、The movable part being flexibly connected with supporting leg，Described movable part is connected to connector，Described connector is connected to and the first gear and the second gear，Described first gear and the second gear all engage setting with tooth bar，Described locking mechanism is connected with governor motion，Make locking mechanism can control the distance between the first gear and the second gear under manpower is got involved，And the first gear and the engagement of the second gear can be made，Due to the first gear、Engaging each other between the second gear and tooth bar achieves the locked of governor motion.
Specifically, described locking mechanism includes movable frame, the first gear shaft, the second gear shaft, described first gear and the second gear are arranged in movable frame respectively through the first gear shaft and the second gear shaft, being provided with spring, the mutual hinged short arm of force and the long arm of force between described first gear shaft and the second gear shaft, the described short arm of force and/or the long arm of force are connected to spanner.
Specifically, described movable frame, the first gear shaft, the second gear shaft constitute above-mentioned connector.
This utility model compared with prior art, has the advantages that
Structure of the present utility model can realize quick lock in and quick release, and is not easy to break down.
This utility model simple in construction, is worth large-scale promotion to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model released state.
Fig. 2 is the structural representation of this utility model lock-out state.
Wherein, accompanying drawing labelling is as follows: 1-supporting leg, 2-supportive body, 3-tooth bar, 4-the first gear, 5-the second gear, 6-movable part, 7-movable frame, the short arm of force of 8-, the long arm of force of 9-.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment
As shown in Figure 1 and 2, double-rack-and-pinion self-locking device, including supporting leg 1, supportive body 2, governor motion and locking mechanism.Described supporting leg and supportive body chain connection so that supportive body can be supported by supporting leg, and realize the adjustment to supportive body height by regulating the angle between supporting leg and supportive body.
Described governor motion includes first gear the 4, second gear 5, tooth bar 3 and movable part 6.Described locking mechanism includes movable frame the 7, first gear shaft, the second gear shaft, spring, each other hinged short arm of force 8 and the long arm of force 9, spanner.
Being provided with tooth bar bottom described supportive body, described supporting leg chain connection has movable part.Described movable frame is provided with the first gear shaft and the second gear shaft, described first gear shaft and the second gear shaft are cased with the first gear and the second gear respectively, described movable frame goes back chain connection and has movable part, i.e. movable part one end and supporting leg chain connection, the other end and movable frame chain connection.Described movable frame is arranged on below tooth bar, first gear, the second gear are engaged with tooth bar respectively, it is provided with chute bottom described supportive body, described movable frame also includes the sliding part that can slide in above-mentioned chute, supportive body and movable frame are flexibly connected, and movable frame can slide relative to supportive body, due to the setting of the first gear and the second gear, first gear and the second gear all can slide on tooth bar, it is convenient to adjust the height of supportive body.
Two identical springs of specification it are connected between described first gear shaft and the second gear shaft, the hinged short arm of force and the long arm of force each other, the described short arm of force and long arm of force one end away from chain connection point it is also associated with respectively with the first gear shaft, the second gear shaft is fixing is connected between described first gear shaft and the second gear shaft.The described short arm of force and the long arm of force are all connected to L-type spanner, make when manual control wrench position, the angle between the short arm of force and the long arm of force can be regulated, thus driving the change of the spacing of the first gear shaft and the second gear shaft so that the first gear and the second gear both can separate and can also engage.
In the present embodiment, described movable frame, the first gear shaft, the second gear shaft constitute the connector connecting movable part and the first gear, the second gear.
It is very convenient that described governor motion makes the angular adjustment between supporting leg and supportive body get up, locking mechanism can locked governor motion, make the angle between supporting leg and supportive body locked, will not change due to the effect of the gravity of supportive body or other external force.
During use, pull spanner so that between the short arm of force and the long arm of force, angle becomes big, and the first gear and the second gear are not at engagement, it is achieved unlock.When unclamping spanner, due to the elastic force of spring so that the first gear and the engagement of the second gear return, due to the first gear, engaging each other between the second gear and tooth bar so that the first gear and the second gear all cannot slide, it is achieved locking.
