The utility model discloses medical C type arm rotational locking device includes that the arm holds in the palm and the rotation axis, rotation axis one end stretches into the arm and holds in the palm insidely and hold in the palm fixed connection with the arm, and the rotation axis other end links to each other with locking mechanism, and locking mechanism can follow circumference and hold the rotation axis tightly, locking mechanism installs on the fixed bolster.
Description
Technical field
This utility model relates to field of medical device, particularly relates to the rotating locking apparatus of a kind of diagnostic device being applied to Medical C arm.
Background technology
The X-ray production apparatus being mounted with C-arm is widely used at medical instruments field, the C-arm of such X-ray production apparatus of major part can rotate along trunnion axis, but need to be any limitation as along trunnion axis rotation angle range to C-arm, otherwise when the C arm anglec of rotation is excessive, it is easy to cause wire to be wrapped on machine.It is currently used for the rotation Ii miter of C-arm contacting spacing or touch-switch is set generally by block and block, is controlled by circuit spacing.Such as a kind of X-ray production apparatus disclosed in patent of invention CN104042229 and C-arm rotating mechanism thereof, being arranged on the central shaft on supporting seat including supporting seat and one end, central shaft can drive supporting seat to rotate.The rotary spacing of central shaft is offseted and realizes with the first block and the second block by sliding block in moving process.This limit method is once it is determined that stop structure, C-arm rotation angle range will be difficult to regulate, X-ray production apparatus is made to use underaction, the demand of every-day medical cannot be met, and block can only the side of centrally disposed axle, spacing process can cause unbalance stress on central shaft, it is also desirable to bigger power carries out spacing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of uniform and stable coupling mechanism force of can providing, it is possible to make the Medical C arm rotating locking apparatus of the free smooth rotation of C-arm and simple in construction.
This utility model Medical C arm rotating locking apparatus, including arm holder and rotating shaft, described rotating shaft one end is stretched into inside arm holder and is fixed with arm holder and is connected, and the rotating shaft other end is connected with retaining mechanism, retaining mechanism can hold rotating shaft tightly from circumference, and described retaining mechanism is arranged on fixed support.
This utility model Medical C arm rotating locking apparatus, wherein said retaining mechanism includes locking sleeve, the inner face of locking sleeve is arranged on fixed support, described rotating shaft passes from locking sleeve is internal, the barrel of locking sleeve offers opening, the barrel of opening both sides is respectively arranged with connecting portion and lower connecting portion, on upper connecting portion and lower connecting portion, corresponding processing has screwed hole, locking screw axle is threaded connection with upper connecting portion and lower connecting portion, and locking screw axle is provided with clamping screw and lock handle.
This utility model Medical C arm rotating locking apparatus, wherein said rotating shaft reaches processing on the axis body outside retaining mechanism cannelure, is provided with axle card in cannelure, and axle card contacts with the outer face of locking sleeve.
This utility model Medical C arm rotating locking apparatus, wherein said rotating shaft is each side provided with a rotary sleeve, and two rotary sleeves are separately mounted to the fixed support left and right sides.
This utility model Medical C arm rotating locking apparatus difference from prior art is in that in this utility model Medical C arm rotating locking apparatus, and arm holder is connected with Medical C arm, arm holder simultaneously is fixing with one end of rotating shaft to be connected, arm entrusts dynamic C-arm when rotating freely, rotating shaft is concomitant rotation also, when rotating to appointment position, by the retaining mechanism installed on fixed support, rotating shaft is locked.Rotating shaft can be held tightly by the retaining mechanism in this utility model from the circumference of rotating shaft, it is possible to coupling mechanism force is evenly distributed to rotating shaft surrounding, strengthens the stability of locking, also more laborsaving, and then reduces the workload of operator, improves work efficiency.Retaining mechanism adopts band brake type locking simultaneously, therefore the rotation of rotating shaft is not had any restriction, so can make the stress equalization of C-arm when the parallel placement of C-arm or arbitrarily angled placement, so that the operation that C arm rotates is lighter, stable.
Below in conjunction with accompanying drawing, Medical C arm rotating locking apparatus of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model Medical C arm rotating locking apparatus；
Fig. 2 is the side view of this utility model Medical C arm rotating locking apparatus.
Detailed description of the invention
As depicted in figs. 1 and 2, this utility model Medical C arm rotating locking apparatus includes arm holder 1 and rotating shaft 3, and arm holder 1 is fixing with C-arm to be connected, and is provided with fixed support 9 on the right side of arm holder 1.Fixed support 9 right-hand member is provided with retaining mechanism.Retaining mechanism includes locking sleeve 8, and the left side of locking sleeve 8 is arranged on the right side of fixed support 9, and the barrel of locking sleeve 8 offers opening.The barrel of the upper and lower both sides of opening is respectively arranged with connecting portion 11 and lower connecting portion 12.On upper connecting portion 11 and lower connecting portion 12, corresponding processing has screwed hole.Locking screw axle 6 is threaded connection with upper connecting portion 11 and lower connecting portion 12, and locking screw axle 6 is provided with clamping screw 10 and lock handle 5.Rotating shaft 3 left end stretches into inside arm holder 1 and fixes with arm holder 1 and is connected, and rotating shaft 3 right-hand member also reaches on the right side of locking sleeve 8 through locking sleeve 8.Rotating shaft 3 reaches processing on the axis body on the right side of retaining mechanism cannelure, is provided with axle card 7 in cannelure, and axle card 7 contacts with the right side of locking sleeve 8, and axle card 7 is for limiting locking sleeve 8 and the position of rotating shaft 3.Each side being provided with a rotary sleeve 2 (2`) on rotating shaft 3, two rotary sleeves 2 (2`) are separately mounted to fixed support 9 left and right sides.
The operation principle of this utility model Medical C arm rotating locking apparatus is as follows: first rotational lock handle 5 and clamping screw 10, distance between upper connecting portion 11 and lower connecting portion 12 increases, the dynamics that locking sleeve 8 holds rotating shaft 3 tightly is less, rotating shaft 3 can be freely rotatable in locking sleeve 8, then hand rotation arm holder 1, arm holder 1 is rotated axle 3 and rotates；When turning to appointment position, now need locking rotating rotating shaft 3, it is prevented to be rotated further, rotational lock handle 5, distance between connecting portion 11 and lower connecting portion 12 in reduction, increase locking sleeve 8 and hold the dynamics of rotating shaft 3 tightly, when locking completely, stop the rotation lock handle 5, and the position of upper connecting portion 11 and lower connecting portion 12 is fixed by rotational lock bolt 10, namely rotating shaft 3 is locked completely, it is impossible to rotate.
Embodiment described above is only that preferred implementation of the present utility model is described; not scope of the present utility model is defined; under the premise designing spirit without departing from this utility model; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims are determined.
