Description
Technical Field
The utility model relates to a ball joint field, concretely relates to formula ball joint is inhaled to magnetism.
Background
Some flexible diagnosis and treatment heads are often needed in medical equipment, and the diagnosis and treatment heads can be conveniently positioned at a certain part of the body of a patient to be kept for a period of time in the diagnosis and treatment process, so that the operation is convenient, the positioning is accurate, and the safety and the reliability are required.
The ball joint has the characteristics of flexible rotation and few movable dead angles, and the diagnosis and treatment joint is arranged on the ball joint in more use modes in the existing medical equipment. However, the positioning of the common ball joint needs to be locked manually, the diagnosis and treatment head is easy to shift in the locking process and needs to be adjusted continuously, and inconvenience is brought to operators. Some are still diagnose the head and need direct contact patient's health, diagnose the in-process patient health and inevitably have little removal, and ordinary ball joint locking back rigidity can not move about, diagnoses the head and can not remove along with patient's health by a small margin together, not only causes the location inaccurate easily, can bring certain discomfort for the patient moreover.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a location is free, does not need the magnetism of manual locking to inhale formula ball joint, and ball joint can make the small size removal of the first self-adaptation patient of diagnosing of connection above.
The utility model adopts the following technical proposal:
the utility model provides a formula ball joint is inhaled to magnetism, includes spheroid and joint socket, the joint socket includes the magnetic steel sleeve, is fixed with left magnet steel and right magnet steel in the magnetic steel sleeve, and left magnet steel has magnetism and magnetism opposite with right magnet steel, accompanies the division board between left magnet steel and the right magnet steel, and the top of left magnet steel and right magnet steel is the quarter spherical structure of indent, and two quarter spherical structures and position between the two constitute the recess of a hemisphere face, the spheroid physical stamina is placed in the recess, and spheroidal surface agrees with the recess mutually, and left magnet steel and right magnet steel pass through magnetic attraction with the spheroid absorption in the recess, and the spheroid can rotate in a flexible way in the recess.
Preferably, a screw is fixedly connected to the ball.
Preferably, the ball is made of a steel material.
Preferably, the spacer is made of a non-magnetic material.
Preferably, the left magnetic steel and the right magnetic steel are consistent in shape.
Preferably, the top end of the isolation plate is lower than the edges of the concave quarter spherical structures of the left magnetic steel and the right magnetic steel.
The utility model has the advantages that:
the utility model provides a magnetic attraction type ball joint, the ball body is absorbed in the groove through the magnetic attraction force, and the ball body can freely and flexibly move and stop at any position in the groove by the magnetic attraction force, and the magnetic attraction type ball joint does not need to be locked manually and is convenient to operate; the spheroid can with diagnose first fixed connection, can adapt to the small size removal of diagnosing the head, keeps original position of diagnosing, and the magnetic attraction that needs to overcome is less moreover, can not cause the discomfort for the patient.

Detailed Description
With reference to fig. 1 and 2, a magnetic ball joint includes a ball 1 and a socket 2.
The sphere 1 is a standard sphere and is made of metal materials with good magnetic conductivity, such as steel.
The sphere 1 is fixedly connected with a screw 3 which can be connected with a diagnosis and treatment head and the like.
The joint seat 2 comprises a magnetic steel sleeve 4, a left magnetic steel 5 and a right magnetic steel 6 are fixed in the magnetic steel sleeve 4, the left magnetic steel and the right magnetic steel are consistent in shape, the left magnetic steel and the right magnetic steel are opposite in magnetism, and an isolation plate 7 is clamped between the left magnetic steel and the right magnetic steel.
In order to reduce the interference of the magnetism of the magnetic steel to the outside, the material of the magnetic steel sleeve 4 adopts non-magnetic conductive metal such as copper.
The isolation plate 7 is made of non-magnetic conductive material, and the isolation plate 7 is used for preventing the left magnetic steel 5 and the right magnetic steel 6 from being mutually adsorbed together.
The tops of the left magnetic steel and the right magnetic steel are both concave quarter spherical structures, and the top end of the isolating plate is lower than the edges of the concave quarter spherical structures of the left magnetic steel and the right magnetic steel.
Two quarter spherical structures and position between the two constitute the recess of a hemisphere face, and the spheroid can be placed in the recess, and spheroidal surface agrees with the recess mutually, and left magnet steel and right magnet steel pass through magnetic attraction and adsorb the spheroid in the recess, and the spheroid can rotate in a flexible way in the recess to rely on magnetic attraction to stop optional position in the recess.
Because the magnetic poles of the left magnetic steel 5 and the right magnetic steel 6 are opposite and are closer, strong magnetic attraction force is generated on the groove. The spheroid 1 adsorbs on the joint seat 2, not only benefits from the magnetic attraction that left magnet steel and right magnet steel produced separately, more benefits from the magnetic attraction that produces each other between left magnet steel and the right magnet steel, also makes the spheroid can obtain more even adsorption affinity to can diagnose the head with the assurance and fix a position in that each direction is firm.
During the use, one section of joint seat is fixed on diagnosing equipment through magnetic steel sleeve, and the spheroid is connected with diagnosing the head, and spheroid 1 can overcome magnetic attraction nimble motion on joint seat 2, relies on the magnetic attraction to stop at the optional position. If the body of a patient moves slightly in the diagnosis and treatment process, the diagnosis and treatment head in contact with the body can also move correspondingly due to being fixed on the ball body, the original diagnosis and treatment position is kept, the magnetic attraction force required to be overcome is small, and discomfort can not be caused to the patient.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
