Abstract

The utility model relates to a movable joint of a human body model, which belongs to the fields of mannequin props, adult dolls, doll toys and the like. The anti-dropping device comprises an upper connecting piece, a hemispherical joint ball seat, a hollow joint ball, an anti-dropping check ring, a permanent magnet block, a wave bead positioning screw and a lower connecting piece. The method is characterized in that: the hollow joint ball is made of magnetic conductive material and is adsorbed together with the hemispherical joint ball seat under the action of the magnetic attraction of the permanent magnet block to form a joint capable of freely moving in multiple directions and multiple angles. The flexibility of the joint movement can be adjusted by the size and the number of the permanent magnet blocks and the friction coefficient of the hollow joint ball and the hemispherical joint ball seat. The wave ball positioning screw passes through the through hole on the surface of the hollow joint ball, so that the joint can be stopped at any position of posture. The range of the joint movement can be adjusted by changing the height of the anti-drop retainer ring.

Description

Movable joint of human body model

Technical Field

The utility model relates to a movable joint of a human body model, which belongs to the fields of mannequin props, adult dolls, doll toys and the like.

Background

The manikins are frequently used in real life and comprise dress model props, adult dolls, toy dolls and the like, the structures of the manikins are required to have higher human body simulation effects, most of the manikins on the market have poor simulation effects at present, particularly, the movable joints of the manikins are inflexible, complex in structure and high in manufacturing cost, so that the manufactured manikins are very stiff, the body actions are single, the manikins cannot be put into different beautiful postures, and the aesthetic effects of people are greatly influenced.

The utility model has the following contents:

to the problem that exists above, the utility model provides a movable joint of human body model, the limbs that enable human body model move about freely to can put out the posture of various differences, with the high emulation of human body activity. The utility model adopts the technical proposal that: the movable joint of the human body model comprises an upper connecting piece, a hemispherical joint ball seat, a hollow joint ball, an anti-falling baffle ring and a lower connecting piece;

go up connecting piece and hemisphere joint ball seat fixed connection, its surface of hemisphere joint ball seat processes out the little through-hole of a certain amount and the screw hole of a certain amount uniformly, and a permanent magnet piece is all fixed mounting to little through-hole the inside, and a ripples pearl set screw is all installed to screw hole the inside.

The lower connecting piece is fixedly connected with the hollow joint ball, a plurality of small through holes are uniformly processed on the whole surface of the hollow joint ball, the diameter of each small through hole is slightly smaller than that of the wave bead positioning screw, and the hollow joint ball is made of a magnetic conductive material.

The anti-drop retainer ring is a hollow ball table, the inner diameter and the outer diameter of the ball table are equal to the size of the hemispherical joint ball seat, the height of the ball table is determined according to the moving range of the joint, the moving range is large, and the height of the ball table is small; the moving range is small, and the height of the table is large. The anti-drop check ring is fixedly connected with the hemispherical joint ball seat.

In above technical scheme, hollow joint ball adsorbs together with hemisphere joint ball seat under the magnetic attraction effect of permanent magnet piece, forms a freely movable joint that can diversely move about with the multi-angle. In the technical scheme, the distance between the wave bead positioning screws and the hole distance on the surface of the hollow joint ball are equal or integral multiple, so that the swing of any amplitude of the hollow joint ball can be ensured, and the wave beads of at least two wave bead positioning screws can be clamped into the small holes on the surface of the hollow joint ball, thereby playing a role in positioning posture.

The technical scheme has the following advantages:

1. the movable joints of the human body model can be suitable for all main movable joints of the human body, including shoulder joints, elbow joints, wrist joints, knee joints, crus subtalar joints, cervical vertebrae, lumbar vertebrae and the like, as long as one size is designed. Therefore, the movable joint of the human body model can be conveniently produced in a large scale, and the cost can be greatly reduced.

2. According to different structures and purposes of the human body model, the movable joint of the human body model can fix any posture of the limb through the friction force of the hollow joint ball and the hemispherical joint ball seat without processing a small hole on the surface of the hollow joint ball.

3. The movable joint of the human body model has the advantages of simple and compact structure, light weight, easy manufacture and low manufacturing cost. The permanent magnet block and the wave bead positioning screw are standard parts and are easily bought in the market.

Drawings

FIG. 1 is a front view of the structure of the present invention

FIG. 2 is a top view of the structure of the present invention

FIG. 3 is a left side view of the structure of the present invention

In the figure (1), an upper connecting piece; (2) a hemispherical joint ball seat; (3) a hollow joint ball; (4) an anti-drop retainer ring; (5) a permanent magnet block; (6) a wave bead positioning screw; (7) and a lower connecting piece.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings. The upper connecting piece (1) is welded with the right top end of the hemispherical joint ball seat (2). A plurality of small round holes and at least 2 screw holes are uniformly processed on the surface of the hemispherical joint ball seat (2). A permanent magnet block (5) is fixed in each small round hole, and a ball positioning screw (6) is arranged in each screw hole.

The lower connecting piece (7) is welded with the bottom end of the hollow joint ball (3), a plurality of small round holes are uniformly processed on the whole ball surface of the hollow joint ball (3), and the size of each small round hole is slightly smaller than that of the wave bead positioning screw (6).

The unprocessed hemispherical joint ball seat is cut off a part of the top part according to the moving range of different joints of a human body, and a hollow round table at the lower part of the hemispherical joint ball seat is taken as an anti-falling retainer ring (4).

The hollow joint ball (3) is adsorbed with the hemispherical joint ball seat (2) under the action of the magnetic attraction of the permanent magnet block (5) to form a joint capable of freely moving in multiple directions and multiple angles. Under the action of external force, the beads in the bead positioning screws (6) are clamped in different small holes, so that the limbs can be fixed at a position of a certain posture, and the movable joint of the human body model and the movable joint of the human body are highly simulated. The sample manufactured by the embodiment is ideal in all aspects and achieves the expected effect.
