Fig. 2 is the outward appearance for the chassis of placing the mounting ultrasonic device.Chassis has for the mounting table of placing ultrasonic unit.The location of chassis and ultrasonic unit can arrange for example 4 platform feet at ultrasonic unit, in the mounting table of chassis guide portion and fitting portion is set.When placing ultrasonic unit, make the platform foot along guide portion to front slide, arrive fitting portion after, platform foot and fitting portion tabling, thus ultrasonic unit is positioned at preposition.Among Fig. 2,2-a is the fenestra that arranges for the turnover of little hook 3-b, 3-c.
Fig. 3 is the sketch map of the locking mechanism of chassis.
In Fig. 3, have handle 3-a in the locking mechanism, handle 3-a is provided with slotted hole 3-f, is provided with axis of guide 3-e among the slotted hole 3-f, and axis of guide 3-e is fixed on the turning cylinder 3-d.Handle 3-a utilizes axis of guide 3-e to prevent rotation with respect to turning cylinder 3-d, and utilizes slotted hole 3-f to limit axial displacement.At turning cylinder 3-d two little hook 3-b are arranged, turning cylinder 3-d is fixed on the same angle, and come with two fixing with little hook 3-c phase interlock with connecting shaft 3-g respectively.Therefore after ultrasonic unit being loaded into the precalculated position of dedicated trolley, 3-a clockwise rotates with handle, 4 fixing 4 component for fixing 1-a of place with little hook 3-b, 3-c and ultrasonic unit will be anchored to together, and ultrasonic unit just has been fixed on the dedicated trolley like this.
In Fig. 3, locking mechanism also has cam body 4-a and is arranged on the position vertical with the turning cylinder 3-d of cam body 4-a, and withstands on the tabletting 5-a of cam body 4-a with the elastic force of spring 5-b, and the structure of this cam body 4-a and tabletting 5-a will be in aftermentioned.
Fig. 4 is the locking releasing process sketch map of locking mechanism.
Along with the rotation of handle 3-a, little hook 3-b, 3-c are penetrated and hook aperture from component for fixing 1-a macropore, thus the mounting ultrasonic device.
Fig. 5 a and 5b are the handle of locking mechanism and the structural representation of cam.Wherein Fig. 5 b is cam among Fig. 5 a structural representation when forwarding different angles to.On handle 3-a, be provided with cam, this cam comprises external cam 4w and cam body.External cam 4w is that a radius is greater than the circular arc body of turning cylinder 3-d.Cam body is made of with cam 4-c and baffle plate 4-d with cam 4-b, releasing locking.On cam, locking is with one side 4-e with the initial surface of cam 4-b and the terminal surface removed with cam 4-c, and removing with the initial surface of cam 4-c is 4-f simultaneously together with locking terminal surface with cam 4-b.The sagittal plane of 4-e face and 4-f face relative external cam 4w respectively with it forms two lines of rabbet joint up and down.Locking with cam 4-b and remove with cam 4-c except these with other parts simultaneously, 4-d separates with baffle plate.Axis of guide 3-e is mobile in slotted hole 3-f, and handle 3-a is directed to a 3-e and is limited between assigned position mobile by the effect of spring 3-h.
The sketch map of the flank of cam structure when Fig. 6 a-6c is locking mechanism of the present invention locking.
If operator's clockwise direction swing handle is arranged on the position vertical with the turning cylinder of cam so, and withstands on tabletting 5-a on the cam with spring 5-b, will be along locking with the curved surface of cam 4-b slide (referring to Fig. 3).After arriving the terminal surface 4-f of locking with cam 4-b, shown in Fig. 6 c, tabletting 5-a is stuck in down in the line of rabbet joint, and handle just can't be rotated further again, and the rotation of so little hook 3-b, 3-c also just has been fixed, and final ultrasonic unit is locked.
The sketch map of the flank of cam structure when Fig. 7 a-7c is locking mechanism release of the present invention.
When if the operator wants to unlock, under lock-out state, handle 3-a is pressed into (left side of Fig. 5) forward, this moment, axis of guide 3-e was positioned at the right-hand end of slotted hole 3-f.Tabletting 5-a will move to the initial surface of removing with cam 4-c from the terminal surface that locks with cam 4-b position like this, and as previously described, these two faces are positioned at one side 4-f.If at this moment handle 3-a is rotated to counter clockwise direction, tabletting 5-a can slide along the curved surface of removing cam 4-c, tabletting 5-a arrive to remove the terminal surface 4-e with cam 4-c, and rotation will stop (Fig. 7 c), and at this moment the operator just can feel and removed.The operator takes away hands from handle, spring 3-g will rebound handle 3-a, the comes out of engagement of the parts 1-a of the fixedly usefulness of the bottom of little hook 3-b, 3-c and ultrasonic unit, and tabletting will be got back to the position that the initial surface of cam 4-b is used in locking like this.
Here said cam refers generally to the shape that section is camber line, in the present invention, as a preferred implementation, uses cam 4-b for locking, begins to terminal surface from initial surface, and its radius radially increases gradually; Use cam 4-c for removing, begin to terminal surface from initial surface, its radius radially increases gradually.But because locking is with one side 4-e with the initial surface of cam 4-b and the terminal surface of removing with cam 4-c, removing with the initial surface of cam 4-c and locking is with one side 4-f with the terminal surface of cam 4-b, and therefore locking is with cam 4-b with to remove the direction of the radially radius increase of using cam 4-c opposite.So in locking process, when tabletting 5-a uses the curved surface of cam 4-b to slide along locking, the dynamics of operating handle can be felt to strengthen gradually, and in releasing process, when tabletting 5-a uses the curved surface of cam 4-b to slide along releasing, the dynamics of operating handle also can be felt to strengthen gradually, thereby has improved operability and reduced the probability of maloperation.
In addition, because locking is used cam 4-b and is removed with cam 4-c in other parts except initial surface and terminal surface, 4-d separates with baffle plate, so can prevent when swing handle 3-a, tabletting 5-a can move about between locking is with cam 4-b and releasing cam 4-c, thereby has prevented maloperation.
In the present embodiment, as long as swing handle 3-a just can lock, and when release, need firmly push ahead handle 3-a and carry out backward rotation and could remove, therefore can prevent the problem of the latch-release that the casual maloperation owing to the operator produces reliably.Thereby can effectively avoid the injury to human body and ultrasonic unit.
Variation
In the above-described embodiments, be provided with cam at handle, by moving to make the position of cam to change to the pivot center direction handle, but also cam can be separated with handle, the action that only allows cam move to the pivot center direction of handle separately.
The formation of having represented variation among Fig. 8.
Be provided with the cam 6-b that can move in the direction of pivot center at turning cylinder 6-a, movable range be by slotted hole and in slotted hole mobile axis of guide 6-e limit.Cam 6-b movably is entrenched on the handle 6-f, and runs through turning cylinder 6-a with the axis of guide 6-e handle is fixed.Cam utilizes spring 3-h that locking is consistent with the initial surface of cam 6-b and the position of tabletting 5-a.At this moment the edge 6-g of cam 6-b protrudes from outside the handle 6-f.
The operator clockwise rotates handle 6-f, perpendicular to the cam turning cylinder, paying the 5-a of the tabletting on cam with the effect of spring 5-b, and will be along the curved surface of cam and slide.After arriving the terminal surface of stationary cam 6-b, handle just can't be rotated further again, and meanwhile, in order to prevent handle 6-f to counterclockwise rotating, tabletting 5-a can be embedded among the cam 6-b.
During releasing, the protuberance 6-g with cam 6-b under lock-out state is pressed on the position that limits with axis of guide 6-e.By being pressed into cam 6-b, cam 6-b will move to the initial surface of removing with cam 6-d from the terminal surface that locks with cam 4-b position with respect to tabletting 5-a.Again handle 6-d is rotated counterclockwise under this state, just can remove fixing.Tabletting 5-a just can't move after arriving the terminal surface of removing cam again, and then because the power cam 6-b of spring 3-h can be rebounded, tabletting has been arrived on the position of locking with the initial surface of cam 6-c.
The locking mechanism of chassis of the present invention, in locking, only just can fix by swing handle infalliblely, and when removing, if be not forced into the operation of handle and rotating cam, handle is rotated to removing direction, and in the operating process of swing handle, because the existence of the baffle plate that arranges makes cam can not move, the trouble that so just can prevent maloperation, neglectful operation and bring is guaranteed safety.
