DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 13 As shown, the present invention provides an artificial embroidery auxiliary device, including a round stretcher 100 and a hoop 200 sleeved on the outer periphery of the round stretcher 100, and also includes a variable telescopic leg 300, which is installed on the outer periphery of the hoop 200.

[0042] The variable telescopic legs 700 are provided with two mounted on the outer periphery of the hoop 200.

[0043] The base 400 is annular and is used to stably place the embroidery auxiliary device.

[0044] The movable slide rail 500 and the fixed slide rail 600, the fixed slide rail 600 is fixedly mounted on the base 400 and installed along the radial direction of the base 400, and the movable slide rail 500 is detachably mounted on the base 400 and symmetrically arranged on both sides of the fixed slide rail 600;

[0045] Among them, a sliding groove 201 is opened on the outer periphery of the clamp 200, and the variable telescopic leg 1 300 and the variable telescopic leg 2 700 are slidably installed in the sliding groove 201 through the sliding frame 301 and the hinge structure 702 respectively. The variable telescopic leg 1 300 and the variable telescopic leg 2 700 both include adjustable telescopic rods respectively hinged on the sliding frame 301 and the hinge structure 702. The bottom end of the adjustable telescopic rod of the variable telescopic leg 1 300 is slidably installed on the fixed slide rail 600, and the adjustable telescopic rod of the variable telescopic leg 2 700 is slidably installed on the movable slide rail 500.

[0046] The present application adopts a circular embroidery frame adapted to an embroidery auxiliary device, and the circular frame 100 and the hoop 200 cooperate to form an embroidery frame to hold the embroidery cloth. The hoop 200 is a three-legged support configuration formed by a variable telescopic leg 1 300 and a variable telescopic leg 2 700. The base 400 is annular and has a large support area, which is used to support the embroidery frame to stand stably. It is more stable than a vertical embroidery frame. The variable telescopic leg 1 300 and the variable telescopic leg 2 700 can slide on the fixed slide rail 600 and the movable slide rail 500 respectively to adjust the position of the legs. It can also assist the embroidery frame to flip. The movable slide rail 500 is detachably connected to the base 400, which can be used to adjust the relative position of the variable telescopic leg 2 700 on the base 400, so that it can avoid the position where embroidery is being done to avoid the defect of blocking the hand. The variable telescopic leg 1 300 and the variable telescopic leg 2 700 are height-adjustable, which can ensure that the embroidery frame can adjust its working height arbitrarily to meet the needs of different embroiderers, and has the characteristics of a wide range of applications.

[0047] like Figure 1 As shown, the adjustable telescopic rod of the variable telescopic leg 300 includes a slide rod 302 hinged on a slide frame 301, a sleeve rod 303 sleeved on the outside of the slide rod 302, and a knob 304 for locking the slide rod 302;

[0048] The maximum telescopic length of the sleeve rod 303 and the knob 1 304 is greater than the diameter of the clamp 200 , and the bottom end of the sleeve rod 303 is slidably mounted on the fixed slide rail 600 through a limiter 306 .

[0049] The slide bar 302 can be freely extended and retracted in the sleeve bar 303 along the vertical direction, and the position can be locked after the extension length is adjusted to the specified position. In this way, the height of the embroidery frame can be adjusted during operation, which is convenient for the embroiderer to operate in the most appropriate posture. Since the variable telescopic leg 1 300 and the variable telescopic leg 2 700 together constitute a tripod support system, the auxiliary device can not only adjust the overall height of the embroidery frame in the vertical height, but also adjust the height of one or two of the legs to achieve the effect of tilting the embroidery frame, so as to meet more requirements for the working posture of the embroidery frame. The maximum extension length of the sleeve bar 303 and the knob 1 304 is set to be greater than the diameter of the hoop 200. This setting is to facilitate the flipping of the embroidery frame. The maximum length of the sleeve bar 303 extending from the knob 1 304 is greater than the circular diameter of the embroidery frame.

[0050] like Figure 1-5 As shown, the adjustable telescopic rod configuration of the variable telescopic leg 2 700 is the same as the adjustable telescopic rod configuration of the slide rod 302 , and the bottom end of the adjustable telescopic rod of the hinge structure 702 is directly slidably connected to the movable slide rail 500 .

[0051] The height of the embroidery frame can be adjusted by the telescopic structure of the variable telescopic leg 2 700 and the variable telescopic leg 1 300, so the height of the embroidery frame can be adjusted as needed in different environments or in the hands of different embroiderers. And when the embroidery frame is turned over, the variable telescopic leg 1 300 and the variable telescopic leg 2 700 also need to cooperate to adjust the height. The telescopic principle of the variable telescopic leg 2 700 is the same as that of the variable telescopic leg 1 300, and both can be locked in height after the height is adjusted to a specified position.

[0052] like Figure 2-5 As shown, the sliding frame 301 and the hinge structure 702 can be locked on the clamp 200 through the knob 2 305 and the knob 3 7024 respectively;

[0053] The relative rotation direction of the sliding rod 302 and the sliding frame 301 is only within the vertical plane where the fixed sliding rail 600 is located.

[0054] These three figures show the dynamic process of the embroidery frame when it is flipped. It gradually rotates and tilts with two hinge structures 702 as fulcrums. The variable telescopic leg 1 300 is connected to the outer periphery of the hoop 200 and the part is a circular arc trajectory in a vertical plane during the rotation process. Therefore, the connection part produces displacement both horizontally along the fixed slide rail 600 and vertically in the height direction. The displacement in the height direction is achieved by the telescopic movement of the slide rod 302 and the sleeve rod 303, while the displacement in the horizontal direction is achieved by the linear motion of the variable telescopic leg 1 300 on the fixed slide rail 600. The above two constraints cause the relative rotation direction of the slide rod 302 and the sliding frame 301 to be only in the vertical plane where the fixed slide rail 600 is located. As a result, after the embroidery frame is flipped, the variable telescopic leg 1 300 and the variable telescopic leg 2 700 reach the other side of the fixed slide rail 600 and the movable slide rail 500 respectively.

[0055] like Figure 6 As shown, the hinge structure 702 includes a movable block 7021, and the movable block 7021 is rollingly installed in the slide groove 201.

[0056] The outer end of the movable block 7021 is connected to a hinge 7023 via a damping universal joint 7022;

[0057] The adjustable telescopic rod of the variable telescopic leg 2 700 is movably hinged with the hinge 7023 .

[0058] The inner end of the movable block 7021 extending to the slide slot 201 is provided with a ball bearing for sliding along an arc track, and a knob 3 7024 is provided below for rotationally locking at the bottom of the slide slot 201 to fix the adjusted position of the movable block 7021. The damping universal joint 7022 is used to rotate arbitrarily with the flipping of the embroidery frame, and the damping universal joint 7022 and the hinge 7023 symmetrically located on both sides constitute a rotation fulcrum with a high degree of freedom.

[0059] like Figure 8 and 10 As shown, the limiter 306 includes a sliding sleeve 3061 slidably mounted on the bottom of the sleeve rod 303, an inner buckle frame 3062 arranged on both sides of the sliding sleeve 3061 for buckling the fixed slide rail 600, a clamping strip 3064 arranged at the bottom end of the sleeve rod 303 and a buckle 3063 installed on the sliding sleeve 3061 for buckling the clamping strip 3064, vertical grooves 3031 are opened on both sides of the bottom end of the sleeve rod 303, and the limiter 306 also includes a bracket installed on the sliding sleeve 3061. The slider 3065 on the inner side of the movable sleeve 3061 is slidably installed in the vertical groove 3031, and a spring 3066 is provided in the vertical groove 3031 for elastically supporting the slider 3065 upward. A step is provided outwardly at the top of the fixed slide rail 600, and an outer edge is provided at the bottom of the inner buckle frame 3062. When the inner buckle frame 3062 moves upward under the upward elastic force of the spring 3066, its outer edge is buckled with the step of the fixed slide rail 600.

[0060] When the embroidery frame is turned over, it is necessary to adjust the position of the variable telescopic leg 300 in a straight line along the fixed slide rail 600, press down the sliding sleeve 3061 and buckle the buckle 3063 with the clamping strip 3064, and the inner buckle frame 3062 is disengaged from the step of the fixed slide rail 600 so that the bottom end of the variable telescopic leg 300 can slide in a straight line along the fixed slide rail 600.

[0061] When the buckle 3063 and the clamping strip 3064 are not engaged, the entire sliding sleeve 3061 moves upward along the vertical slot 3031 or has an upward tendency under the action of the spring 3066, thereby driving the inner buckle frame 3062 upward to engage the step at the top of the fixed slide rail 600, thereby limiting the bottom end of the variable telescopic leg 1 300 to a horizontal position and preventing it from moving. After adjusting the position of the variable telescopic leg 1 300, the buckle 3063 and the clamping strip 3064 are unlocked, so that the sliding sleeve 3061 and the inner buckle frame 3062 rebound and rise.

[0062] like Figure 1 , 11 As shown in FIG. 12 , a plurality of magnetic blocks 401 are disposed on the top surface of the base 400 along the circumferential direction, and the magnetic blocks 401 are symmetrical with respect to the vertical midline of the fixed slide rail 600. Magnetic strips 501 are disposed at the bottom of both ends of the movable slide rail 500, and the magnetic strips 501 at both ends are attracted to the magnetic blocks 401 on both sides of the vertical midline of the fixed slide rail 600 respectively;

[0063] The movable slide rail 500 always remains parallel to the fixed slide rail 600 .

[0064] The magnetic blocks 401 arranged on the base 400 are symmetrical with respect to the center line of the fixed slide rail 600. The magnetic blocks 401 are divided into four groups, each of which is arranged at an equal angle on the base 400. The placement of the magnetic blocks 401 is parallel to the magnetic strips 501 and parallel to the length extension direction of the movable slide rail 500. Therefore, the movable slide rail 500 can adjust its position along the vertical center line direction of the fixed slide rail 600, but the movable slide rail 500 must always be parallel to the fixed slide rail 600 during the adjustment process. The magnetic strips 501 on the movable slide rail 500 can be respectively attached to two magnetic blocks 401 symmetrical with respect to the center line of the fixed slide rail 600, so that its own posture can be ensured to be parallel to the fixed slide rail 600. Therefore, when the hinge structure 702 is fixed to the hoop 200, the bottom end of the variable telescopic leg 2 701 can move linearly along the extension direction of the movable slide rail 500. It is convenient to adjust the flipping of the embroidery frame.

[0065] Furthermore, by adjusting the position of the movable slide rail 500 on the base 400, the position of the variable telescopic leg 2 700 and the hoop 200 can be adjusted. In order to meet the embroidery posture requirements of the embroiderer, when the position near the variable telescopic leg 2 700 forms an unfavorable condition for blocking the hand, the position of the movable slide rail 500 can be adjusted so that the variable telescopic leg 2 700 can slide and adjust its position along the periphery of the hoop 200 to avoid the current embroidery area on the embroidery frame, which is convenient for the embroiderer to operate.

[0066] For example Fig.13 As shown, the angle of the movable slide rail 500 can be adjusted arbitrarily to make the magnetic strip 501 thereon and the magnetic block 401 on the base 400 attract and reach a stable state, thereby adjusting the position and tilt angle of the variable telescopic leg 2 700 to more flexibly avoid the embroidery range on the embroidery cloth as the embroidery position of the embroiderer changes.

[0067] like Figure 1 , 11 As shown in FIG. 12 , the top surface of the base 400 is parallel to the top surface of the magnetic block 401 , and the bottom surface of the magnetic strip 501 is parallel to the bottom surface of the movable slide rail 500 .

[0068] The top surface of the base 400 is parallel to the top surface of the magnetic block 401, and the bottom surface of the magnetic strip 501 is parallel to the bottom surface of the movable rail 500. This arrangement can ensure that the surface of the movable rail 500 and the base 400 is flat, and the movable rail 500 can ensure good smoothness when moving on the base 400, and prevent the defect of inconvenience caused by jamming. In order to eliminate the sense of frustration when moving on it, a layer of plastic film can be pasted on the bottom of the movable rail 500 or the surface of the base 400 to increase the thickness and offset the edge conflict between the magnetic strip 501 and the magnetic block 401, so as to overcome the frustration defect.

[0069] The working principle and use process of the present invention:

[0070] The embroidery cloth is stretched on the embroidery frame by the round frame 100 and the hoop 200, and the variable telescopic leg 1 300 and the variable telescopic leg 2 700 are locked with the hoop 200 respectively. When the embroidery needs to be turned over, the limiter 306 is unfastened from the bottom of the fixed slide rail 600, and it is moved to the other end along the fixed slide rail 600, and at the same time, the connection between the variable telescopic leg 2 700 and the hoop 200 is used as the fulcrum for the rotation of the embroidery frame. If the height of the variable telescopic leg 1 300 and the variable telescopic leg 2 700 is not enough to cope with the flipping, the variable telescopic leg 1 300 and the variable telescopic leg 2 700 can be extended to compensate. When the fixed slide rail 600 moves to the position aligned with the variable telescopic leg 2 700, the embroidery frame is in a vertical state. At this time, the variable telescopic leg 2 700 can be moved in the opposite direction to achieve flipping and rotation.

[0071] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
