Abstract
The utility model discloses a resistant image finger bone collateral structure of buckling, including the interior bone collateral and the spring that can buckle and warp, on the surface of bone collateral including the spring housing, interior bone collateral is the columnar structure, interior bone collateral is including the inner core that can buckle and warp, the inner core is made by metal material. Compared with the prior art, the inner skeleton vein comprising the inner core is arranged, the spring is sleeved outside the inner skeleton vein, and the bending radius is increased due to the addition of the spring, so that the bending damage is reduced; a gap is reserved between the spring and the inner skeleton, and the inner skeleton rotates in the spring at a certain angle randomly in each bending process, so that the bending position is changed, and the service life is prolonged.
Description
Technical Field
The utility model relates to a doll, in particular to a bending-resistant doll finger bone collateral structure for a doll.
Background
At present, the appearance of the doll is accepted and loved by more and more people, the doll with movable joints can be put into different postures according to different requirements to achieve the expected effect, but in the current doll, in order to better simulate the bending of human fingers, metal wires such as copper wires are often adopted as finger skeletons, then soft rubber is coated outside, in use, the hand part of the doll is a part which is often played by a user, and in the process of repeated bending, the user often breaks the copper wires in the fingers due to metal fatigue, so that the doll cannot be used continuously.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a resistant bent doll finger bone collateral structure, the technical problem that solve is the life who improves the doll finger bone collateral.
In order to solve the above problem, the utility model discloses a following technical scheme realizes: the utility model provides a resistant image finger bone collateral structure of buckling, is including the interior bone collateral and the spring that can buckle the deformation, the spring housing is on the surface of the interior bone collateral, interior bone collateral is the columnar structure, interior bone collateral is including the inner core that can buckle the deformation, the inner core is made by metal material.
Further, the inner core is composed of at least one strand of wire.
Further, the inner bone vein also comprises an outer skin, and the outer skin is coated on the outer surface of the inner core.
Further, the outer skin is made of a non-metallic material.
Further, the outer skin is made of a plastic material.
Further, the springs are spaced apart on the medial collateral.
Further, the free length of the spring is equal to the length of the inner bone complex.
Further, the outer surface of the spring is wound with a wire.
Further, the inner core is made of copper, aluminum, silver or iron material.
Compared with the prior art, the utility model has the advantages that the inner skeleton vein comprising the inner core is arranged, the spring is sleeved outside the inner skeleton vein, the bending radius is increased due to the addition of the spring, and the bending injury is reduced; a gap is reserved between the spring and the inner skeleton, and the inner skeleton rotates in the spring at a certain angle randomly in each bending process, so that the bending position is changed, and the service life is prolonged.
Drawings

Fig. 2 is a cross-sectional view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and fig. 2, the utility model discloses a bending-resistant doll finger bone collateral structure, which comprises a bendable inner bone collateral 1 and a spring 2, wherein the spring 2 is sleeved on the outer surface of the inner bone collateral 1, the inner bone collateral 1 is in a columnar structure, the inner bone collateral 1 comprises a bendable inner core 11, and the inner core 11 is made of a metal material; specifically, the cross section of the internal collateral bone 1 is circular, the inner diameter of the spring 2 is slightly larger than the outer diameter of the internal collateral bone 1, so that the spring 2 can be sleeved on the internal collateral bone 1, and the spring 2 is an extension spring.
As shown in fig. 2, the internal bone matrix 1 further includes an outer skin 12, and the outer skin 12 is coated on the outer surface of the inner core 11. Specifically, the outer skin 12 is made of a non-metallic material; preferably, the outer skin 12 is made of a plastic material.
As an embodiment of the present invention, the spring 2 is sleeved on the inner collateral bone 1 by adopting a spacing arrangement.
As shown in fig. 1, as another embodiment of the present invention, the free length of the spring 2 is equal to the length of the inner skeleton 1, so that the spring 2 completely covers the inner skeleton 1.
When in use, one end of the utility model is connected with the palm of the doll.
In the utility model, the inner core 11 is composed of at least one strand of metal wire, and the diameter of the inner core is 2-4 mm; when the wire is composed of more than two strands of metal wires, the twisted wire is formed into a twist shape; preferably, the inner core 11 is made of copper, aluminum, silver or iron material.
After the soft rubber is coated, the soft rubber can fix the spring 2; alternatively, it is also possible to wind a wire around the outer surface of the spring 2 so that the spring 2 does not come loose.
Compared with the existing common doll finger bone collateral structure, the utility model greatly improves the bending resistance of the doll fingers; actual measurement parameters: starting angle of finger: the included angle between the palm and the palm is 90 degrees; bending amplitude: 180 degrees; bending frequency: for 1 second.
In the test, the finger of the prior art will break after being bent 15 times on average, and the finger of the utility model can reach more than 100 times.
