Wherein, central shaft 3 is a hollow axle, and its inside is useful on the circuit that connects ultrasound emission unit 6, water route (not shown) etc.Shell 2 then is enclosed within the outer and fixed center axis 3 of central shaft 3, and shell 2 leading sections have second flank 28, thus can link to each other with headgear for ultrasonic therapy 1, and with headgear for ultrasonic therapy 1 outer surface of formation ultrasonic therapeutic rifle jointly.
Preferably, like Fig. 5, Fig. 6, shown in Figure 8, to terminal, shell 2 inwalls are connected with structures such as first muscle 21 that is used for fixing central shaft 3, second muscle 22, the 3rd muscle 22 in turn by front end.
Concrete, second linkage unit comprises second flank 28, stop collar 4, stage clip 5, press section; Wherein:
Stop collar 4 is enclosed within outside the central shaft 3 and is positioned at shell 2; It has at least one roof pressure face that can contact with the top cover protruding 15 of headgear for ultrasonic therapy 1, and (this sentences two and is example; Obviously the quantity of this roof pressure face, position etc. should with protruding 15 couplings of top cover), and stop collar 4 be configured to can moving axially to expose or to cover the screw thread inlet 281 of second flank along central shaft 3.
Preferably, like Fig. 7, shown in Figure 9, has at least one spacing hole 44 (this sentences two and is example) on the stop collar 4; Shell 2 is connected with the limited post 24 (certainly, limited post 24 also can be connected on the central shaft 3) that stretches in the spacing hole 44; Central shaft 3 axially on, the size of spacing hole 44 is greater than the size of limited post 24, on the circumferencial direction of central shaft 3, limited post 24 and spacing hole 44 matched in clearance.Wherein, " matched in clearance " is meant on the circumferencial direction of central shaft 3; Has less clearance (for example every side 0.02mm-0.05mm) between limited post 24 side wall surfaces and spacing hole 44 internal faces; Thereby it can not hinder stop collar 4 motion in the axial direction, but can stop the rotation of stop collar 4 around central shaft 3 basically.
Certainly, above-mentioned spacing hole 44, limited post 24 also can be replaced by other structure, such as stopper slot etc.; Perhaps also can not establish similar structures, and allow stop collar 4 to rotate (certainly, this moment, press section just can not be located on the stop collar 4) around central shaft 3; In a word, as long as guarantee that spacing hole 44 can axially moving forward and backward along central shaft.
Like Fig. 7, shown in Figure 8; Stage clip 5 is enclosed within outside the central shaft 3; More near the end of central shaft 3, and be configured to can be to central shaft 3 front ends pushing stop collar 4 (position, length etc. that are stage clip 5 should guarantee to be in compressive state, and can push stop collar 4) always than stop collar 4 for it.
Under the effect of stage clip 5, when the roof pressure face did not contact with headgear for ultrasonic therapy 1, stop collar 4 can withstand on its most forward position that can reach, thereby the screw thread of " covering " second flank inlet 281 is threaded with prevention; And when the roof pressure face received the roof pressure of top cover protruding 15, stop collar 4 can move and the screw thread inlet 281 of " exposing " second flank to central shaft 3 ends again, was threaded with second flank 28 to allow first flank 18.The end of stage clip 5 can be as shown in Figure 8, withstand on first muscle 21 that shell 2 inwalls are connected on; Certainly, this first muscle 21 also can be connected on the central shaft 3, or first muscle 21 also can be replaced by the structure of other forms such as fixture block.
Preferably, to shown in Figure 9, stop collar 4 middle parts have the stage clip ring 45 of outside protrusion like Fig. 7, and stage clip 5 front ends withstand on the stage clip ring 45; And stop collar 4 stretches between stage clip 5 and the central shaft 3 in the part of stage clip ring 45 rear sides.Obviously; In this preferred structure, stage clip 5 is big with the contact area of stop collar 4, and the latter half of quilt " folder " of stop collar 4 is between stage clip 5 and central shaft 3; Thereby can reduce the skew of stage clip 5 in motor process, guarantee that it can be stable to stop collar 4 applied thrusts.
Certainly, if there is not above-mentioned stage clip ring 45, and stage clip 5 directly withstands on the terminal surface of stop collar 4, also can realize the basic purpose of present embodiment.
Press section; It is configured in the process that is threaded of first flank 18 and second flank 28, to squeeze off the top cover of headgear for ultrasonic therapy 1 protruding 15 (position that promptly movement locus of this press section when being threaded should protruding 15 places of cover, inswept top, and can top cover protruding 15 be squeezed off).
Preferably, to shown in Figure 9, the leading section of stop collar 4 has at least one pair of first vertical and continuous each other contact surface 41 and second contact surface 42 (this sentence first contact surface 41 and second contact surface 42 respectively have two be example) like Fig. 7; Wherein, first contact surface 41 is axial vertical with central shaft 3, and it is the roof pressure face; The radial parallel of second contact surface 42 and central shaft 3 (axis of central shaft 3 is passed on the plane at second contact surface, 42 places in other words), and it is press section.
That is to say; Like Fig. 7, shown in Figure 9; The front end of stop collar 4 has the right angle face, is first contact surface 41 with the axial vertical of central shaft 3 in the right angle face, and it just is used for and top cover protruding 15 contact and make stop collar 4 to the terminal mobile roof pressure face of the ultrasonic therapeutic rifle body of a gun; And in the right angle face with the radial parallel of central shaft 3 be second contact surface 42, it just is used to squeeze off the press section of top cover protruding 15.When headgear for ultrasonic therapy 1 is connected with the ultrasonic therapeutic rifle body of a gun; Top cover protruding 15 earlier contact first contact surfaces 41 (being the roof pressure face) and with stop collar 4 tops to central shaft 3 ends; The screw thread inlet 281 that exposes second flank; 2 on headgear for ultrasonic therapy 1 and shell are relatively rotated and be threaded, this moment, stop collar 4 rotated (because the effect of spacing hole 44 and limited post 24, so stop collar 4 can not be with respect to shell 2 rotations) with shell 2 with respect to headgear for ultrasonic therapy 1; Thereby second contact surface 42 (being press section) will push up cover protruding 15 from side direction and squeeze off, and clamp-on in the above-mentioned slit 9 and block.
Obviously, because first contact surface 41 and second contact surface 42 are exactly roof pressure face and press section, so preferably the quantity with top cover protruding 15 is consistent for their quantity.
The roof pressure face and the press section of this form are simple in structure, are easy to processing, as long as opening a right angle mouth at the leading section of stop collar 4 can form roof pressure face and press section simultaneously, and the top corresponding with it cover protruding 15 also is provided with easily.
Certainly; Press section also can be other form; For example for being connected the inside or outwardly directed radially protuberance on central shaft 3, shell 2, the stop collar 44 etc., this protuberance can be along with the ultrasonic therapeutic rifle body of a gun rotates in the process of being threaded, and contact top cover protruding 15 and it is squeezed off.In a word, the concrete structure of press section (position, shape, size etc.) has multiple choices, just no longer it is described in detail one by one at this, as long as it can squeeze off top cover protruding 15 in the process of being threaded.
Preferred, like Fig. 7, shown in Figure 9, stop collar 4 leading sections also have at least one recess 43 that links to each other with first contact surface 41 (this sentences two recesses 43 and is example).Obviously; As long as can covering the screw thread inlet 281 of second flank, stop collar 4 can realize its effect; And will second flank 28 and the front end of shell 2 all cover; If the area that stop collar 4 front ends cover is excessive, on the contrary maybe be in the process of being threaded wait other parts to scratch (or claiming interference) etc. with shell 2, influence is threaded.For this reason, can offer the recess 43 that links to each other with first contact surface 41,, also can reduce stop collar 4 sizes simultaneously, lower its material consumption and cost can reduce stop collar 4 and the probability that other parts interfere at stop collar 4 leading sections.
Preferably, like Fig. 6, shown in Figure 8, have at least two outwards contact rings 32 of protrusion on the central shaft 3, contact ring 32 and stop collar 4 matched in clearance.Wherein, " matched in clearance " is meant in the footpath of central shaft 3 and makes progress; Have less clearance (for example every side 0.02mm-0.05mm) between stop collar 4 internal faces and contact ring 32 outside wall surface, thus stop collar 4 can central shaft 3 axially on motion, can not squint again, rock etc.Because central shaft 3 contact with stop collar 4 through contact ring 32, thereby its contact area with stop collar 4 is less, can make stop collar 4 smooth more steady in axial motion, and the volume that the while can reduce central shaft 3 again reduces its material consumption and cost.
Preferably, like Fig. 6, shown in Figure 8, have on the central shaft 3 shrink to its front end, can with the conical surface 31 of the tip engages of the connecting pipe 13 of headgear for ultrasonic therapy 1.That is to say that as previously mentioned, when the ultrasonic therapeutic rifle body of a gun combined with headgear for ultrasonic therapy 1, the end of connecting pipe 13 can " push up " on the conical surface 31, thus the sealing cooling water.
Certainly,, do not have contact ring 32, the conical surface 31 etc. on the central shaft 3, can realize the basic purpose of present embodiment yet if there is not recess 43 on the stop collar 4.
Obviously, in the present embodiment, the axis of shell 2, central shaft 3, stop collar 4 etc. should overlap, thus they axially, radially, circumferencial direction etc. also is identical.
