[0003] Decorative picture frames are mostly rectangular and are used as hanging racks for paintings and as protective gear. A decorative picture frame is a rectangular structure composed of multiple wooden frame strips. In the process of assembling the multiple wooden frame strips, the joints between the frame strips are usually fixed by glue or mortise and tenon joints. In particular, during the glue process, it is necessary to apply external force to bring the frame strips closer together to further reduce the gaps between the frame strips, and at the same time, to shape the picture frame.
[0004] In the field of arts and crafts supplies technology, the shaping device for decorative picture frame production is a key piece of equipment to ensure the quality and production efficiency of decorative picture frames. Existing shaping devices for decorative picture frame production can usually only shape picture frames of a specific size. When it is necessary to produce picture frames of different sizes, the corresponding shaping molds or equipment need to be changed, which not only increases production costs but also reduces production efficiency.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0024] Example 1
[0025] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a shaping device for producing decorative picture frames, including a picture frame body 1. A shaping mechanism 2 for shaping the picture frame body 1 is provided on the outside of the picture frame body 1. The shaping mechanism 2 includes a U-shaped block 21 provided on the outside of the picture frame body 1. A fixing rod 27 is fixedly connected inside the U-shaped block 21. A first fixing plate 25 and a second fixing plate 26 are rotatably connected to the outside of the fixing rod 27. An installation cylinder 24 is sleeved on the outside of the fixing rod 27. A spring 28 is fixedly connected inside the fixing rod 27. One end of the spring 28 away from the fixing rod 27 is fixedly connected to the inner wall of the installation cylinder 24. A strap 22 is fixedly connected inside the U-shaped block 21. One end of the strap 22 away from the U-shaped block 21 is fixedly connected to the outer wall of the installation cylinder 24. A shaping clamp 23 is provided on the outside of the strap 22. The shaping mechanism 2 is also provided with a limiting mechanism 3 for limiting position and a tightening mechanism 4 for tightening the strap 22.
[0026] Specifically, the end of the mounting cylinder 24 is fixedly connected to the opposite surfaces of the first fixing plate 25 and the second fixing plate 26, the strap 22 is set on the outside of the picture frame body 1, and four shaping clamps 23 are provided, with the inner walls of the four shaping clamps 23 slidingly connected to the outer wall of the strap 22.
[0027] In the field of arts and crafts supplies technology, the production of decorative picture frames requires the use of a shaping device to shape and bond the frame strips together. During the bonding process, pressure is applied between the frame strips to reduce gaps and simultaneously shape the frame. A slot for a spring-loaded spring 28 is provided at the center of the fixing rod 27. One end of the spring-loaded spring 28, away from the mounting cylinder 24, is fixed inside the slot, while the other end is fixed to the inner wall of the mounting cylinder 24. One end of the strap 22 is fixed to the outer wall of the mounting cylinder 24, and the strap 22 is wrapped around it. Pulling the strap 22 causes the mounting cylinder 24 to rotate outside the fixing rod 27. Since one end of the spring-loaded spring 28 is fixed to the inner wall of the mounting cylinder 24, and the other end is fixed to the inside of the fixing rod 27, the frame... The rotation of the mounting cylinder 24 causes the internal spring 28 to rotate, storing elastic potential energy. When the strap 22 is of appropriate length, the four shaping clamps 23 can be placed sequentially at the four corners of the corresponding frame body 1. Then, the strap 22 is released, and the elastic potential energy stored in the spring 28 is released, causing the mounting cylinder 24 to rotate in the opposite direction. This causes the strap 22 to rewind onto the surface of the mounting cylinder 24. Since there are four shaping clamps 23, and the inner walls of the four shaping clamps 23 are slidably connected to the outer wall of the strap 22, the contraction of the strap 22 will cause the four shaping clamps 23 to lock into the four corners of the frame body 1, thus completing the shaping work on the frame body 1. Through the setting of the shaping mechanism 2, the frame body 1 of different sizes can be quickly and adaptively shaped, and the strap 22 can be quickly and automatically stored without producing an excessively long strap 22, thus facilitating operation by the staff.
[0028] When in use, pull the strap 22. When the length of the strap 22 is appropriate, the four shaping clamps 23 can be placed in sequence at the four corners of the frame body 1 to be shaped. Then, release the strap 22. The strap 22 will contract due to the action of the spring 28, which will cause the four shaping clamps 23 to lock into the four corners of the frame body 1, thereby completing the shaping work on the frame body 1.
[0029] Example 2
[0030] Reference Figures 1-6This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that it provides a shaping device for producing decorative picture frames. The limiting mechanism 3 includes an outer gear ring 31 rotatably connected to the outside of the first fixed plate 25. An inner gear ring 32 meshes with the outside of the outer gear ring 31. A connecting plate 33 is fixedly connected to the outside of the inner gear ring 32. A connecting rod 34 is fixedly connected to the ends of both connecting plates 33. A pressure plate 35 is fixedly connected to the ends of both connecting rods 34 through one end of the U-shaped block 21. A first spring 36 is sleeved on the outside of each connecting rod 34. The tightening mechanism 4 includes mounting grooves 41 evenly opened at the ends of the first fixed plate 25. Limiting blocks 42 are evenly arranged inside the first fixed plate 25. A pawl 43 is fixedly connected to the end of each limiting block 42 away from the mounting groove 41. A second spring 44 is fixedly connected to the end of each limiting block 42 away from the pawl 43. A ratchet 45 is fixedly connected to the inside of the outer gear ring 31.
[0031] Specifically, the end of the first spring 36 is fixedly connected between the opposing surfaces of the pressure plate 35 and the U-shaped block 21, the limiting blocks 42 are all slidably connected inside the mounting groove 41, the ends of the pawls 43 near the limiting blocks 42 are all slidably connected inside the mounting groove 41, the end of the second spring 44 away from the limiting blocks 42 is fixedly connected to the inner wall of the mounting groove 41, and the pawls 43 and the ratchet 45 mesh with each other.
[0032] The connecting plate 33 is used to fix the internal gear ring 32 and the connecting rod 34. The pressure plate 35 is set above the U-shaped block 21. The connecting rod 34 is slidably connected inside the U-shaped block 21. When the pressure plate 35 is pressed down, the first spring 36, which is located between the opposing surfaces of the pressure plate 35 and the U-shaped block 21, will compress and store elastic potential energy for subsequent reset of the pressure plate 35. When the pressure plate 35 is pressed down, the connecting rod 34 will move down accordingly, causing the internal gear ring 32 to move down, thereby disengaging the external gear ring 31 and the internal gear ring 32. At this time, the strap 22 can be pulled freely. When the length of the strap 22 is appropriate, the pressure plate 35 is released, the first spring 36 releases its elastic potential energy, thereby resetting the pressure plate 35. Next, the connecting rod 34 and the internal gear ring 32 are reset, thereby causing the external gear ring 31 and the internal gear ring 32 to re-engage. Since the end of the mounting cylinder 24 is fixedly connected to the opposite surfaces of the first fixed plate 25 and the second fixed plate 26, and the external gear ring 31 is rotatably connected to the outside of the first fixed plate 25, a ratchet 45 is fixedly connected inside the external gear ring 31, and the pawl 43 engages with the ratchet 45. Through the mutual engagement of the external gear ring 31 with the internal gear ring 32, and the pawl 43 with the ratchet 45, the mounting cylinder 24 and the spring spring 28 are limited. At this time, the strap 22 will not retract, making it easier for the worker to place the four shaping clamps 23 in sequence at the four corners of the frame body 1 to be shaped. After placement, the pressure plate is pressed down again. 35. Disengage the outer gear ring 31 and the inner gear ring 32, releasing the limiting effect on the mounting cylinder 24 and the spring 28. At this time, the elastic potential energy stored in the spring 28 is released, causing the mounting cylinder 24 to rotate in the opposite direction. This causes the strap 22 to rewrap around the surface of the mounting cylinder 24. The contraction of the strap 22 causes the four shaping clamps 23 to lock into the four corners of the frame body 1. At this time, the strap 22 contracts only under the action of the spring 28, so the tightening force is relatively small. Then, the lever 46 can be rotated. The lever 46 is evenly fixed to the outside of the second fixing plate 26. The second fixing plate 26 is fixedly connected to the end of the mounting cylinder 24, and the other end of the mounting cylinder 24 is fixedly connected to the first fixing plate 25. The outer gear ring 31 and the inner gear ring 32 are disengaged. 1. Rotate the lever 46 to rotate the mounting cylinder 24 via the second fixed plate 26, thereby causing the strap 22 to continue to contract. During the rotation of the lever 46, the pawl 43 will successively touch the inclined surface of the ratchet 45. The pawl 43 is pressed by the second spring 44 and drives the limiting block 42 to slide towards the mounting groove 41, so that the pawl 43 and the ratchet 45 are disengaged. When the lever 46 is released, the second spring 44 resets the limiting block 42 and the pawl 43, so that the pawl 43 and the ratchet 45 are re-engaged. The pawl 43 and the ratchet 45 are engaged, so that the mounting cylinder 24 will not rotate in the opposite direction, thereby achieving the purpose of tightening the strap 22 and completing the shaping work on the picture frame body 1.
[0033] During use, the operator presses down on the pressure plate 35, compressing the first spring 36 and storing elastic potential energy. The connecting rod 34 then moves downwards, causing the inner gear ring 32 to move downwards, disengaging the outer gear ring 31 and the inner gear ring 32. At this time, the mounting cylinder 24 and the spring 28 are no longer restricted by the engagement of the outer gear ring 31 and the inner gear ring 32. The operator pulls the strap 22, causing the mounting cylinder 24 to rotate outside the fixed rod 27. Since one end of the spring 28 is fixed to the inner wall of the mounting cylinder 24 and the other end is fixed inside the fixed rod 27, the rotation of the mounting cylinder 24 causes the spring 28 to rotate and store elasticity. When the strap 22 is of suitable length and can adapt to the size of the frame body 1 to be shaped, the operator releases the pressure plate 35, the first spring 36 releases its elastic potential energy, causing the pressure plate 35 to reset, which in turn causes the connecting rod 34 and the inner gear ring 32 to reset, so that the outer gear ring 31 and the inner gear ring 32 re-engage. Through the mutual engagement of the outer gear ring 31 and the inner gear ring 32, and the pawl 43 and the ratchet 45, the mounting cylinder 24 and the spring spring 28 are limited, and the strap 22 stops moving. Then, the operator places the four shaping clamps 23 in sequence at the four corners of the frame body 1. After placement, the operator lowers the clamps again. The pressure plate 35 disengages the outer gear ring 31 and the inner gear ring 32, removing the limiting effect on the mounting cylinder 24 and the spring 28. The elastic potential energy stored in the spring 28 is released, causing the mounting cylinder 24 to rotate in the opposite direction. This causes the strap 22 to rewrap around the surface of the mounting cylinder 24. The retraction of the strap 22 causes the four shaping clamps 23 to engage at the four corners of the frame body 1, achieving initial shaping of the frame body 1. To make the shaping more secure, the operator rotates the lever 46. Rotating the lever 46, through the second fixing plate 26, causes the mounting cylinder 24 to rotate, which in turn causes the strap 22 to continue to retract. During the process of lever 46, pawl 43 will successively touch the inclined surface of ratchet 45. Pawl 43 is pressed by the second spring 44 and drives the limiting block 42 to slide towards the mounting groove 41, so that pawl 43 and ratchet 45 are disengaged, allowing the mounting cylinder 24 to continue to rotate and tighten the strap 22. When lever 46 is released, the second spring 44 returns to its deformation, so that the limiting block 42 and pawl 43 are reset, and pawl 43 and ratchet 45 are re-engaged. Pawl 43 and ratchet 45 are locked together, preventing the mounting cylinder 24 from rotating in the opposite direction, thereby maintaining the tightened state of the strap 22 and completing the final shaping of the picture frame body 1.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
