Description

Technical Field

[0001] The utility model belongs to the technical field of dummy models and relates to a connection structure of a dummy model. Background Art

[0002] Traditional mannequins used to display clothing are mainly made of one-piece mannequins with appropriate postures to support and display the style of clothing. However, due to the lack of changes in posture, they cannot be adjusted according to the style of clothing, and are also quite troublesome when putting on and taking off clothing.

[0003] In response to the above problems, people have made various improvements, and some have even applied for patents. For example, Chinese patent literature discloses the movable structure of a model arm [patent number: 01253538.9; application publication number: CN2507341Y]. The arm joint structure is mainly that an inclined surface of appropriate angle is provided on the opposite side surfaces of the upper and lower arm joint ends, and corresponding spherical arc grooves are formed on the two adjacent end surfaces of the upper and lower arms and extend inward to form built-in slots. The slots cooperate with a sleeve rod portion of a sheet-like pivot and a spherical pivot seat, and the sheet-like pivot and the spherical pivot seat are respectively inserted and connected to the joint ends of the upper arm and the lower arm. A groove is preset in the middle part of the spherical pivot seat for the sheet-like pivot and an elastic gasket embedded in the concave annular surface of the sheet-like pivot to be placed. A shaft bolt is used to cooperate with a nut to intersect and pivot and fix the sheet-like pivot and the spherical pivot seat, and the spherical pivot seat is sandwiched between the spherical arc grooves formed on the end surfaces of the upper and lower arms.

[0004] The movable structure of this structure is fixedly connected with the ball-shaped pivot seat and the plate-shaped pivot plate by the shaft bolt and the nut, so that the upper arm and the lower arm can be fixed at different angles. However, if the shaft bolt and the nut of the movable structure of this structure are slightly loose, the upper arm and the lower arm may rotate relative to each other, and the firmness is low. Moreover, when adjusting, the specific adjustment of the upper arm and the lower arm depends entirely on feeling, and the angle adjustment is troublesome. Summary of the invention

[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose a connection structure for a dummy model, and the technical problem solved is how to improve the adjustment accuracy of the connection structure and improve the firmness of the connection structure after positioning.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a connection structure of a dummy model, comprising a first pivot seat, a second pivot seat, a screw rod and a nut, characterized in that the connection structure also includes a spring, the inner side of the first pivot seat has a first annular corrugated groove, the inner side of the second pivot seat has a second annular corrugated groove, the first pivot seat and the second pivot seat are locked by the screw rod and the nut, the first corrugated groove and the second corrugated groove are meshed with each other, the spring is sleeved on the screw rod, and the two ends of the spring act on the head of the screw rod and the nut respectively.

[0007] This connection structure is mainly used to connect the upper arm and lower arm of a mannequin. When in use, loosen the screw and nut, relatively rotate the first pivot seat and the second pivot seat, so that the first corrugated groove passes over the second corrugated groove, rotate to a suitable angle, and then tighten the screw and nut to make the first corrugated groove and the second corrugated groove mesh with each other, so that the first pivot seat and the second pivot seat are positioned relative to each other. In the above process, due to the action of the spring elastic force, the first pivot seat and the second pivot seat are relatively tensioned. Without applying a certain external force, there is no problem of relative rotation between the first pivot seat and the second pivot seat. The first corrugated groove and the second corrugated groove mesh with each other, and each time the first corrugated groove passes over a grid of the second corrugated groove, for example, one grid is 10°, the angle of rotation of the first pivot seat relative to the second pivot seat is controllable, so that the bending angle of the lower arm relative to the upper arm can be accurately controlled, and the adjustment accuracy of the connection structure is improved. The first corrugated groove and the second corrugated groove mesh with each other and cooperate with the locking of the screw and the nut. Even if the screw and the nut are not tightened enough, the first corrugated groove cannot cross the second corrugated groove, and due to the tension of the spring elastic force, the first pivot seat and the second pivot seat will not rotate relative to each other, thereby improving the firmness of the connection structure after positioning the upper arm and the lower arm.

[0008] In the above-mentioned connection structure of a mannequin, the first pivot seat and the second pivot seat are both hemispherical, the first corrugated groove is located at the inner edge of the first pivot seat, and the second corrugated groove is located at the inner edge of the second pivot seat. This structure makes the first pivot seat and the second pivot seat spherical after being fitted together, so that the first pivot seat and the second pivot seat can rotate smoothly relative to each other. The first corrugated groove and the second corrugated groove are located at the edge, and the angle of the first corrugated groove is smaller every time it crosses the second corrugated groove, so that the forearm and the upper arm can be positioned at different angles, thereby improving the adjustment accuracy of the connection structure.

[0009] In the above-mentioned connection structure of a mannequin, the first pivot seat has a first positioning cylinder, the second pivot seat has a second positioning cylinder, the inner end of the first positioning cylinder and the inner end of the second positioning cylinder are positioned by plugging, and the first positioning cylinder and the second positioning cylinder form a mounting channel, the spring and the rod of the screw are both inserted into the mounting channel, the nut can abut against the outer end of the first positioning cylinder, and the head of the screw can abut against the outer end of the second positioning cylinder. This structure is properly arranged to stabilize the connection between the first pivot seat and the second pivot seat, while preventing the screw and spring from being exposed and being disturbed by the outside world, thereby improving stability and thus improving the adjustment accuracy of the connection structure.

[0010] In the above-mentioned connection structure of the mannequin, the first pivot seat further comprises a first receiving groove, the nut is located in the first receiving groove, the second pivot seat further comprises a second receiving groove, the head of the screw is located in the second receiving groove. This structure prevents the screw, nut and spring from being exposed and are not disturbed by the outside world, thus improving stability; at the same time, the external structure of the connection structure is neat.

[0011] In the above-mentioned connection structure of a mannequin, a first connecting arm is fixedly connected to the first pivot seat, and the outer end of the first connecting arm has a protruding first connecting column, a first rotating plate is circumferentially rotatable on the first connecting column, and a first positioning plate is circumferentially positioned and axially movable, a third annular corrugated groove is provided on one side of the first rotating plate, and a fourth annular corrugated groove is provided on one side of the first positioning plate, a first adjusting member is fixedly connected to the first connecting column, and a first elastic member is provided on the outer sleeve of the first adjusting member, one end of the first elastic member acts on the first adjusting member, and the other end acts on the first positioning plate, so that the third corrugated groove and the fourth corrugated groove are meshed with each other.

[0012] The first rotating plate is used to connect the upper arm. Under the action of the elastic force of the first elastic member, the first positioning plate presses the first rotating plate, so that the third corrugated groove and the fourth corrugated groove are meshed with each other, so that the first pivot seat is positioned relative to the upper arm. When adjustment is required, a certain external force is applied to rotate the first pivot seat, and the first pivot seat drives the first positioning plate to rotate. Since the first rotating plate is fixedly connected to the upper arm, the first rotating plate is stationary, thereby overcoming the elastic force of the first elastic member to make the first positioning plate move axially, so that the third corrugated groove passes over the fourth corrugated groove, and the first pivot seat rotates relative to the upper arm. Under the action of the elastic force of the first elastic member, the third corrugated groove and the fourth corrugated groove are meshed with each other, so as to realize the positioning of the first pivot seat relative to the upper arm; the first elastic member is a cylindrical spring, and the first adjusting member is a combination of a screw and a nut. The elastic force of the first elastic member is controlled by rotating the nut.

[0013] In the above-mentioned connection structure of a mannequin, the circumferential edge of the first rotating plate is protruded outside the circumferential edge of the first connecting arm, the circumferential edge of the first rotating plate is protruded outside the circumferential edge of the first positioning plate, and the circumferential edge of the first rotating plate is provided with a first fixing hole for fixing. This structure makes it easy to connect the first rotating plate to the upper arm.

[0014] In the above-mentioned connection structure of a mannequin, a second connecting arm is fixedly connected to the second pivot seat, the outer end of the second connecting arm has a protruding second connecting column, a circumferentially rotatable sleeve is provided with a second rotating plate and a circumferentially positioned axially movable sleeve is provided with a second positioning plate, one side of the second rotating plate has a fifth annular corrugated groove, one side of the second positioning plate has a sixth annular corrugated groove, a second adjusting member is fixedly connected to the second connecting column, a second elastic member is provided on the outer sleeve of the second adjusting member, one end of the second elastic member acts on the second adjusting member, and the other end acts on the second positioning plate, so that the fifth corrugated groove and the sixth corrugated groove engage with each other.

[0015] The second rotating plate is used to connect the lower arm. Under the action of the elastic force of the second elastic member, the second positioning plate presses the second rotating plate so that the fifth corrugated groove and the sixth corrugated groove are meshed with each other, so that the second pivot seat and the lower arm are positioned. When adjustment is required, a certain external force is applied to rotate the lower arm, and the lower arm drives the second rotating plate to rotate. The second rotating plate overcomes the elastic force of the second elastic member to move the second positioning plate axially, so that the sixth corrugated groove passes over the fifth corrugated groove, and the lower arm rotates relative to the second pivot seat. After the sixth corrugated groove passes over the fifth corrugated groove, under the action of the elastic force of the second elastic member, the fifth corrugated groove and the sixth corrugated groove are meshed with each other, so that the lower arm is positioned relative to the second pivot seat. The second elastic member is a cylindrical spring, and the second adjusting member is a combination of a screw and a nut. The elastic force of the second elastic member is controlled by rotating the nut.

[0016] In the above-mentioned connection structure of a mannequin, the circumferential edge of the second rotating plate is protruded outside the circumferential edge of the second connecting arm, the circumferential edge of the second rotating plate is protruded outside the circumferential edge of the second positioning plate, and the circumferential edge of the second rotating plate is provided with a second fixing hole for fixing. This structure makes it easy to connect the second rotating plate with the lower arm.

[0017] Compared with the prior art, the connection structure of a dummy model provided by the utility model has the following advantages:

[0018] 1. The first corrugated groove and the second corrugated groove of the connection structure are meshed with each other. Each time the first corrugated groove passes over a grid of the second corrugated groove, the angle is controllable, so that the rotation angle between the first pivot seat and the second pivot seat can be accurately controlled, and the bending angle of the lower arm relative to the upper arm can be accurately controlled, thereby improving the adjustment accuracy of the connection structure.

[0019] 2. The first corrugated groove and the second corrugated groove of the connection structure are meshed with each other, and cooperate with the locking of the screw and the nut. Even if the screw and the nut are not tightened enough, since the first corrugated groove cannot cross the second corrugated groove, and due to the tension of the spring elastic force, the first pivot seat and the second pivot seat will not rotate relative to each other, thereby improving the firmness of the connection structure after positioning the upper arm and the lower arm.
