[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] like Figures 1 to 2 The embroidery frame safety structure of an embroidery machine shown in the figure includes a support plate 1, an embroidery frame 2 is slidably connected to the top of the support plate 1, a stretcher 3 is fixedly installed inside the embroidery frame 2, a cloth 4 is arranged on the top of the stretcher 3, a connecting rod 5 is fixedly connected to the outer wall of the embroidery frame 2, the connecting rod 5 is slidably connected to the inside of the support plate 1, and a driving rod 6 is fixedly connected to the end of the connecting rod 5 away from the embroidery frame 2; a safety component, the safety component is used to assist the staff to limit and fix the embroidery frame 2, and the safety component is connected to the support plate 1 and the driving rod 6.
[0017] like Figures 3 to 7 As shown, the safety component includes a fixing member 7 fixedly mounted on the bottom of the support plate 1, the fixing member 7 is rotatably connected to the inside of the fixing member 7, the outer wall of the connecting member 8 is provided with a first weakening groove 9, the end of the connecting member 8 away from the fixing member 7 is fixedly connected to a clamping member 10, the side of the clamping member 10 close to the fixing member 7 is fixedly connected to an extension piece 11, the top of the clamping member 10 is fixedly connected to an L-shaped plate 12, the side of the L-shaped plate 12 away from the fixing member 7 is fixedly connected to a gripping piece 13, the outer wall of the L-shaped plate 12 is provided with a second weakening groove 14, and the L-shaped plate 12 is slidably connected to the support plate 1 Inside, a return spring 15 is fixedly installed on the outer wall of the L-shaped plate 12, and the return spring 15 is fixedly installed on the inside of the support plate 1. The top of the L-shaped plate 12 is slidably connected with a push piece 16, and the push piece 16 is arranged inside the support plate 1. A limiting groove 17 is opened inside the support plate 1, and the push piece 16 is slidably connected to the inside of the limiting groove 17. The limiting groove 17 is composed of a straight line segment and a triangular segment. The connection position of the straight line segment and the triangular segment is provided with a protrusion to ensure that when the staff moves the push piece 16 to the connection position of the straight line segment and the triangular segment, they will feel resistance to assist the staff in positioning.
[0018] like Figure 2 and Figure 4As shown, a slide groove 18 is provided inside the support plate 1, and a push rod 19 is slidably connected inside the slide groove 18. The push rod 19 is arranged on one side of the push piece 16. The push rod 19 is slidably connected to the inside of the embroidery frame 2. The push rod 19 is inserted into the inside of the stretcher 3. A clamping piece 20 is provided at one end of the push rod 19. The clamping piece 20 is arranged inside the stretcher 3. The clamping piece 20 is fixedly connected to the inside of the stretcher 3 by a torsion spring, so that the clamping piece 20 can rotate and reset inside the stretcher 3. A smoothing rod 21 is provided on the top of the stretcher 3 and the cloth 4. Handles 22 are fixedly connected at both ends of the smoothing rod 21. A card slot 23 is provided inside the two handles 22. A card block 24 matching the card slot 23 is fixedly installed on the top of the stretcher 3.
[0019] Working principle: When the embroidery frame 2 finishes its work and drives the stretcher 3 back to its initial position, the staff can manually press the holding piece 13, so that the holding piece 13 drives the L-shaped plate 12 to slide down along the inside of the support plate 1 and squeeze the return spring 15 to contract, thereby causing the L-shaped plate 12 to drive the clamping piece 10 to descend and be clamped on the driving rod 6, so that the clamping piece 10 can limit and fix the embroidery frame 2 through the driving rod 6 and the connecting rod 5, preventing the staff from accidentally touching the embroidery frame 2, causing the embroidery frame 2 to drive the connected structure to move, and avoiding damage to the embroidery machine caused by non-working displacement. When the staff needs to stop fixing the driving rod 6, the holding piece 13 can be pulled up, so that the holding piece 13 pulls the clamping piece 10 from the outer wall of the driving rod 6 through the L-shaped plate 12, and stops clamping the driving rod 6. At this time, the embroidery frame 2 loses its limit fixation, and the return spring 15 can also push the L-shaped plate 12 to reset until the connecting piece 8 connected to the clamping piece 10 is parallel to the bottom of the support plate 1 and stops; It should be noted that when the staff does not want to manually limit and fix the embroidery frame 2, they can pull the holding piece 13 down with one hand, so that the holding piece 13 drives the L-shaped plate 12 to descend and squeeze the return spring 15 to retract, until the top of the L-shaped plate 12 coincides with the bottom of the push piece 16 and stops, and then pull the push piece 16 with the other hand, so that the push piece 16 slides along the limiting groove 17 and is connected to the top of the L-shaped plate 12, and then stop pulling the holding piece 13, so that the return spring 15 can push the L-shaped plate 12 to reset, and then the L-shaped plate 12 drives the push piece 16 to disengage from the top of the triangular section of the limiting groove 17, so that the push piece 16 is higher than the top of the support plate 1. At this time, if the embroidery frame 2 returns to its initial position, the embroidery frame 2 will squeeze the push piece 16 when the driving rod 6 moves to the bottom of the extension piece 11, so that the push piece 16 drives the L-shaped plate 12 to slide down along the inside of the support plate 1, and then the push piece 16 re-enters the limiting groove 1 7, thereby making the L-shaped plate 12 squeeze the return spring 15 to contract and push the clamp 10 down, so that the clamp 10 is clamped on the outer wall of the driving rod 6 under the guidance of the extension piece 11, so as to automatically limit and fix the driving rod 6, so that the driving rod 6 can limit and fix the embroidery frame 2 through the connecting rod 5. In the process of the clamp 10 descending and being clamped on the outer wall of the driving rod 6, the clamp 10 first drives the extension piece 11 to descend and press on the top of the driving rod 6. At this time, the clamp 10 is blocked by the driving rod 6 through the extension piece 11, and the second weakened groove 14 on the L-shaped plate 12 and the first weakened groove 9 on the connecting piece 8 begin to deform and accumulate force under pressure until the embroidery frame 2 completely returns to its initial position. The pushing piece 16 is completely squeezed into the interior of the supporting plate 1, and after the driving rod 6 moves to the bottom of the clamp 10, the L-shaped plate 12 and the connecting piece 8 begin to deform and reset, and the clamp 10 is buckled on the outer wall of the driving rod 6 by the stored force; Furthermore, when the driving rod 6 pulls the embroidery frame 2 to move again for work through the connecting rod 5, the driving rod 6 will apply pressure to the clamping piece 10, and the clamping piece 10 will transfer the force it receives to the connecting piece 8 and the L-shaped plate 12, so that the first weakened groove 9 of the connecting piece 8 and the second weakened groove 14 of the L-shaped plate 12 are deformed by the force, and the deformation of the connecting piece 8 and the L-shaped plate 12 will drive the clamping piece 10 to move until the pulling force applied by the driving rod 6 is greater than the force of the clamping piece 10 clamping on the driving rod 6, and the driving rod 6 is separated from the inside of the clamping piece 10, so that the clamping piece 10 automatically stops the limit fixation after receiving a certain force from the driving rod 6, so as to achieve the effect of automatic separation of the clamping piece 10 and the driving rod 6, and at the same time avoid the situation where the staff forgets to cancel the limit fixation of the driving rod 6, resulting in the driving rod 6 and the clamping piece 10 being stuck or damaged. It should be noted that when the driving rod 6 is automatically limited and fixed, the reset of the embroidery frame 2 will drive the push rod 19 to resist the push piece 16, so that the push rod 19 is forced to slide along the inside of the embroidery frame 2 and the stretcher 3 and apply a thrust to the clamping piece 20, thereby causing the clamping piece 20 to rotate and stop clamping and fixing the fabric 4. At this time, the staff can quickly remove the embroidered fabric 4 from the stretcher 3 and replace it with a new fabric 4. When the new fabric 4 is replaced, the staff can pull the push piece 16 along the inside of the limiting groove 17 until the push piece 16 slides to the position where the straight section of the limiting groove 17 is connected to the triangular section and stops. At this time, the push piece 16 is staggered with the push rod 19, so that the push piece 16 no longer contacts the push rod 19, allowing the clamping piece 20 to reset under the action of the torsion spring force and clamp the new fabric 4. At this time, the staff can place the smoothing rod 21 on the top of the new fabric 4 and the stretcher 3, and pull the smoothing rod 2 through the handle 22 1 moves toward the blocking block 24, allowing the smoothing rod 21 to smooth the new fabric 4, allowing the blocking groove 23 on the handle 22 to engage with the blocking block 24, and limiting and fixing the other side of the new fabric 4, so as to facilitate the staff to replace and fix the fabric 4. At the same time, when the embroidery frame 2 moves and works, the driving rod 6 loses the engagement of the blocking piece 10, and the embroidery frame 2 stops squeezing the push piece 16. The return spring 15 will push the push piece 16 to rise and reset through the L-shaped plate 12. Since the push piece 16 is at the connection between the straight section and the triangular section inside the limiting groove 17 at this time, the push piece 16 will rise along the inclined surface of the triangular section of the limiting groove 17 during the process of being pushed up by the L-shaped plate 12 until the push piece 16 disengages from the top of the triangular section of the limiting groove 17 and stops. At this time, the push piece 16 is completely reset. When the embroidery frame 2 returns to its initial position later, the clamping piece 20 can be pushed by the push rod 19 to rotate and open the limiting fixation of the fabric 4.
