Embodiment
To shown in Figure 5, the present embodiment height adjustment mechanism can be applicable to the vehicle carried type ultrasonic instrument as Fig. 1, and it comprises mainframe 7, vertical lifting structure 1, locking assembly 4 and limiting stopper 6.This mainframe 7 is used to support whole height adjustment mechanism.This vertical lifting structure 1 has fixed end and moved end, and this fixed end is fixed on this mainframe, and this moved end is fixed on keyboard 2 or the miscellaneous equipment, can regulate the height of keyboard 2 by this vertical lifting structure 1.This vertical lifting structure is an existing structure, and it comprises the guide rail and the slide block of controllable type air spring and drive thereof.This locking assembly 4 comprises base 42, latch 43, Flexible Reset body 44 and wrench 41.This base 42 is fixed on the mainframe 7, and this base 42 has the mounting hole 423 of lateral direction penetrating, has step surface 421 in this mounting hole.This latch 43 comprises first shaft part 431 and second shaft part 432, and this first shaft part 431 and second shaft part 432 are wholely set and coaxial line, this first shaft part 431 mounting hole 423 of laterally packing into.This Flexible Reset body 44 can be at transversal stretching, and it is as spring.This Flexible Reset body 44 is laterally placed, it is enclosed within on first shaft part 431 and the mounting hole 423 of the base 42 of packing into, this first shaft part 431 also has step surface 433, and the two ends of this Flexible Reset body 44 are replaced the step surface 433 of first shaft part and the step surface 421 of base respectively.First shaft part 431 of this latch 43 is the mounting hole 423 of part protuberate basic unit in the horizontal, and spanner 41 is fixed on this extension.This base 42 has the tight groove 424 of U-lock and two U types are separated locked groove 425 towards the end face 420 of spanner 41, and this locking slot 424 is conciliate locked grooves 425 and communicated, and the degree of depth of this locking slot 424 is greater than the degree of depth of separating locked groove 425.Conciliate the locking and unlocking two states that locked groove 425 is set spanner 41 by spanner 41 being placed the different locking slot of the degree of depth 424, can realize the locking of vertical lifting structure 1 when spanner places darker locking slot 424, spanner places the more shallow release that can realize vertical lifting structure 1 when separating locked groove 425.Extract spanner and rotation, just spanner can be placed locking or released state.
Limiting stopper 6 has working surface 61 and is positioned at the cross spacing hole 62 of these working surface 61 belows, this working surface 61 is towards second shaft part 432 of latch, this second shaft part 432 is positioned on the rising trace of this working surface 61, this working surface 61 is for can laterally promoting the inclined-plane or the arc surface of latch 43, and this spacing hole 62 mates with second shaft part 432 of latch.The upper and lower side of this limiting stopper 6 is fixed with upper and lower pad 63,64 respectively.Second shaft part 432 of latch is provided with the last positioning block 434 corresponding with going up pad 63, and base 42 is provided with the block 422 corresponding with last positioning block 434, and under released state, block 422 can guarantee that positioning block 434 has only a kind of state vertically downward.This mainframe 7 is provided with the following positioning block 71 corresponding with following pad 64.Should go up the below that pad 63 is positioned at spacing hole 62, this time positioning block 71 is positioned at the below of this time pad 64.This upper and lower positioning block 434,71 is used to limit the movement travel of vertical lifting structure 1 lifting.This upper and lower pad 63,64 has elasticity and can play buffer function.
When changing air spring, need locking keyboard earlier, and then change air spring.During replacing, spanner 41 is placed lock state, keyboard 2 rises under the drive of vertical elevator mechanism 1, limiting stopper 6 can be along with this vertical lifting structure 1 rises together, when the working surface 61 of limiting stopper touches second shaft part 432 of latch 43, this working surface 61 withstands second shaft part 432, elevating movement can be converted to the transverse movement of latch 43, compression Flexible Reset body 44 in latch 43 fallback procedures; When the spacing hole 62 that rises to second shaft part 432 and limiting stopper when limiting stopper aligns, under the restoring force effect of Flexible Reset body 44, second shaft part, 432 transverse movements and insert spacing hole 62 realize the locking to the keyboard lifting, at this moment just can change the air spring of vertical lifting structure.When spanner was in released state, keyboard can lifting.
When released state, avoid external impacts in order to protect air spring when the limit position, need control the stroke of air spring, reserve the idle stroke of 5mm at the limit position of air spring compression and elongation.When spanner 41 during at released state, the last positioning block 434 of latch 43 vertically downward, during the 5mm place, the last positioning block 434 of latch 43 withstands pad 63 before air spring rises to limit position, keyboard 2 stops to rise, air spring is protected at the limit position that rises.During the 5mm place, the following pad 64 of limiting stopper 6 belows can be pressed onto on the following positioning block 71 of mainframe 7 before air spring drops to limit position, and keyboard 2 stops to descend, and air spring is protected at the limit position that descends.
In the present embodiment, operate vertical lifting structure, when making keyboard rise to the extreme higher position, keyboard lockout.After the lifting structure locking, latch can be used for bearing external force, has effectively protected air spring, makes air spring avoid external impacts, has prolonged the working life of air spring greatly; After the lifting structure locking, do not need external force to support and just can dismantle air spring very easily, effectively raise the maintainability of system.At the limit position of the compression and the elongation of air spring, reserve the idle stroke of 5mm, promptly 5mm limits the reduction of keyboard before the short status of compression, and 5mm limits the rising of keyboard before the long status of elongation.At the maximum rating of air spring elongation, keyboard is pinned; When extracting (replacing) air spring, air spring is an elongation state freely, changes air spring like this and just is easy to, and replacing person does not need with removing the pressurized gas spring energetically.
This height adjustment mechanism can be widely used in instrument, the test and measuring equipment of motion control apparatus, medical diagnostic equipment, automation control appliance, video editing and manufacturing mechanism, medical imaging system, industry and the science of machine, microscope and vision system, CAD/CAM/CAE equipment and the computer graphics equipment of electromechanicsization.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
