Description
Technical field
The present invention relates to medicine equipment instrument, being specifically related to the torque wrench for loading and unloading ultrasonic medical equipment operation tip.
Background technology
Ultrasonic medical equipment comprises ultrasonic dental scaler, piezosurgery osteotomy machine etc., is contacted with working face by the operation tip of ultrasonic vibration, realizes physical method and removes dental surface spot, tartar or the specific function such as deep.Operation tip is arranged on the handle of ultrasonic medical equipment by screw thread (internal thread or external screw thread), and the rear portion of operation tip is generally cylinder, and offers spanner position on the cylinder, and instrument easy to use carries out screwing installation.In order to be suitable for different functional requirements, simultaneously also in order to the demand of health, often needing operation tip to disassemble from handle, carrying out replacing or sterilizing.In order to ensure user in use can effectively loading and unloading point; avoid the screw thread on operation tip or handle damaged in cargo handling process; and protect the hand of user in loading and unloading point process not by operation tip scratch; screw installation process usually to need to use torque wrench, the dynamics of loading and unloading point is carried out rationally and effective control.
Existing operation tip torque wrench is generally dome-shaped structure, offers an aperture in the bottom of spanner, then operation tip is inserted in this aperture, after turn spanner, just can realize the charge and discharge operations of operation tip.If notification number is the Chinese utility model patent of CN202497259U, the torque wrench of operation tip can be clamped, comprise spanner lid, spanner seat and offer at its axle center place the rubber cushion that namely a through hole clamps position mouth, spanner lid is set with and is fixed on the inside of spanner seat, the axle center place of spanner lid is provided with a through spanner position mouth, elastic mounting is in the upper surface of spanner lid, and clamping position mouth on rubber cushion is coaxially relative with the spanner position mouth that spanner covers.The program utilizes the clamping position cause for gossip on rubber cushion now to clamp operation tip, but the spanner position mouth covered due to spanner and the clamping position mouth on rubber cushion are the airtight circulus that up/down perforation, surrounding are one-body molded or be connected, operation tip can only be inserted from the bottom of limiter wrench, and thus such torque wrench can only operate not having bending, that crooked radian is little or head is less operation tip.When operation tip has plural structure comparison that is bending or operation tip special, operation tip just cannot be inserted into inside from clamping position, the below mouth of spanner, and then has no idea to use existing spanner to operate this special operation tip.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of torque wrench that may be used for particular job point handling in ultrasonic medical equipment, operation tip can be clamped.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
For loading and unloading the torque wrench of ultrasonic medical equipment operation tip, comprise spanner lid and spanner seat, the top of described spanner seat is set with and is fixed in spanner lid, spanner seat bottom is the hollow columnar structures of end sealer, spanner seat sealing offers through hole and spanner position mouth, and the operation tip that the periphery in spanner seat bottom and sealing offer through spanner position mouth from outside to inside wears groove; Also comprise a mold insert, described mold insert is fixed on sealing top, mold insert offers through hole and mold insert position mouth with mouth corresponding position, spanner position, and corresponding operation tip is worn the operation tip that groove place also offers through mold insert position mouth from outside to inside and is worn groove on mold insert, mold insert also offers the draw-in groove of through mold insert position mouth, in this draw-in groove, is provided with the fastener that can clamp operation tip.Described operation tip wears groove can make operation tip snap in torque wrench from the side, thus the operation tip of various shape can be inserted in limiter wrench, realizes the handling of operation tip.
Be inserted in torque wrench for the ease of holding with operation tip, described operation tip wears the half that camber line corresponding to groove is equal to or less than spanner seat lower circumference.
Preferably, described fastener is jump ring, and its working end is that crotch-shaped penetrates mold insert position mouth and blocks operation tip.
In order to fastener can be avoided outwards and upwards to skid off when stressed, described mold insert position mouth is consistent with spanner position mouth-shaped, and described draw-in groove forms for upwards offering from mold insert bottom surface.
Preferably, described fastener is jump ring, and the outer linear of this jump ring is arranged, and middle part slopes inwardly, and inside penetrates mold insert position mouth to projecting inward outward-dipping formation crotch again and blocks operation tip; Described draw-in groove and the space that be reserved with for jump ring working end resilience consistent with jump ring shape.The inward-outward direction of described jump ring, refers to the direction, the center of circle of relative mold insert.
Preferably, described mold insert position mouth passes spanner position mouth to lower convexity, and the through projection of mold insert position mouth; Described draw-in groove forms for offering from mold insert bottom surface along protruding lateral surface, and draw-in groove termination is from protruding lateral surface through mold insert position mouth.
Preferably, described fastener is jump ring, and the upper straight of this jump ring is arranged, the inside inclined downward in middle part, and bottom inwardly below is protruded outwards inclined downward again and formed crotch and penetrate mold insert position mouth and block operation tip; Described draw-in groove and the space that be reserved with for jump ring working end resilience consistent with jump ring shape.The inward-outward direction of described jump ring, refers to the direction, the center of circle of relative mold insert.
In order to the effect that torque wrench can be made to have moment of torsion and limiter, described spanner lid inwall is provided with ratchet, is provided with has flexible ratchet on spanner seat top.When spanner lid rotates, described ratchet slips over to ratchet successively from the groove between the adjacent ratchet of spanner lid inwall, plays the effect of limiter.The quantity of described flexible ratchet is preferably 1 or 2.
Preferably, described spanner seat bottom and operation tip are worn on the relative periphery of groove and are offered through hole, are provided with projection laterally along through hole edge.Through hole is set, discharges inner liquid after being convenient to torque wrench cleaning, arbitrarily roll when arranged outside projection can prevent torque wrench from keeping flat.
Compared with prior art, the present invention has the following advantages:
1, operation tip wears groove from through spanner position, spanner seat bottom mouth (with mold insert position mouth), operation tip is made to snap in torque wrench from the side, thus making the operation tip of most shape can insert in limiter wrench, torque wrench operation tip applicatory type is more;
2, draw-in groove was arranged with mating of jump ring, not only firmly can clamp operation tip, and structure is simple, was easy to realize; The other draw-in groove of two kinds of modes and the design of jump ring, can reach the effect of firm clamping operation tip;
3, the ratchet of spanner lid inwall and the ratchet of spanner seat, can reach torque value and the limiter effect of expection during use, the reliability that available protecting operation tip and handle threads coordinate, and increases the service life.
