Description

Technical Field

[0001] This utility model relates to the field of transfer printing technology, and in particular to a quick-fixing structure for steel mesh frame inserts. Background Technology

[0002] In the transfer printing process, the stencil is the core carrier for pattern transfer. The fixing accuracy between the stencil and the frame directly affects the integrity and positional accuracy of the transferred pattern. The stencil used for transfer needs to be flat and taut through the frame to ensure that the stencil and the substrate are tightly attached during printing, avoiding problems such as blurry or misaligned patterns caused by loose stencil.

[0003] In existing technologies, steel mesh is generally connected by bolts. However, this method of fixing requires special tools such as wrenches for both installation and disassembly. The operation is complicated. During installation, the bolt holes of the steel mesh and the frame must be aligned one by one, and the bolts must be tightened one by one to ensure the tension of the steel mesh. During disassembly, the operation must be reversed, and the bolts must be loosened one by one. The whole process takes a long time. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a steel mesh frame insert-type quick fixing structure.

[0005] This utility model proposes a quick-fixing structure for steel mesh frame inserts, including a steel mesh, inserts that are inserted and engaged at the edges of the steel mesh, and the steel mesh and inserts that are engaged and connected to a frame strip through a first slot and a second slot. The adjacent ends of the frame strip are engaged and connected to a corner connector through a guide groove, a sliding groove, a protruding edge, a protruding handle, a protruding strip, a baffle, and a third slot.

[0006] Furthermore, several holes are opened on the edge of the steel mesh, and several plugs are connected to the bottom of the plug. The plugs are adapted to the holes, and the plugs are inserted and engaged inside the holes.

[0007] Furthermore, a first slot and a second slot are respectively opened at the bottom end of the frame strip, and the steel mesh and insert are correspondingly inserted into the first slot and the second slot.

[0008] Furthermore, the first slot and the second slot together form an "eight" shape, with an opening reserved in the middle to facilitate the insertion of the steel mesh and insert.

[0009] Furthermore, a protruding edge is connected to the top of the frame strip and above the slide groove, and the protruding edge engages inside the third slot.

[0010] Furthermore, the top of the frame strip is provided with a connecting guide groove and a sliding groove.

[0011] Furthermore, the two ends of the corner connector are connected to protruding shanks inside the guide groove. The bottom of the inner side of the protruding shank is connected to a protruding strip, and the top is connected to a baffle. A third slot is reserved between the protruding strip and the baffle. The protruding strip is engaged inside the slide groove.

[0012] Furthermore, the steel mesh, inserts, frame strips, and corner connectors are made of metal and are assembled into a single steel mesh unit.

[0013] Furthermore, the insert extends through the steel mesh 1 to the front end of the first slot opening, and the lower part of the insert is provided with several protruding teeth, which abut against the edge of the first slot.

[0014] The beneficial effects of this utility model are as follows: When fixing the steel mesh, no auxiliary parts such as bolts are required throughout the process, which enables the rapid assembly of the steel mesh and the frame for transfer printing, greatly shortening the assembly time. The multi-clamping structure ensures the flatness of the steel mesh and the overall rigidity of the frame during long-term use, effectively avoiding the deviation in transfer accuracy caused by steel mesh displacement and frame deformation, and meeting the production requirements of high efficiency, low cost and high stability in transfer printing.

[0015] When in use, the steel mesh is placed in a fixed mechanism. The fixed mechanism is equipped with cylinders around the perimeter for fixation, thus fixing the frame strips and inserts, which makes the force on the entire mesh frame very even. Attached Figure Description

[0026] Reference Figure 1-5 This utility model proposes a quick-fixing structure for a steel mesh frame with inserts, comprising a steel mesh 1, inserts 2, frame strips 3, and corner connectors 4. These four components are assembled sequentially using a layered interlocking method to ultimately form a complete steel mesh frame structure. The specific technical solution is as follows:

[0027] The edge of the steel mesh 1 is evenly provided with several insertion holes 11. Correspondingly, the bottom end of the insert 2 is integrally formed with several plugs 21. The number and size of the plugs 21 are perfectly matched with the insertion holes 11 on the steel mesh 1. After splicing, the plugs 21 are inserted into the insertion holes 11.

[0028] The bottom end of the frame strip 3 is provided with a first slot 31 and a second slot 32. The two slots are symmetrically distributed and together form an "eight" shape structure. An opening is reserved in the middle, which can guide the steel mesh 1 and the insert 2 to quickly align with the slot, reducing the assembly difficulty. On the other hand, the inner wall of the slot forms a bidirectional clamping force on the steel mesh 1 and the insert 2, improving the connection stability.

[0029] In addition, in order to achieve the splicing and forming of the frame strip 3, the top of the frame strip 3 is provided with a guide groove 33 and a sliding groove 34, which are connected to each other. The width of the guide groove 33 is greater than that of the sliding groove 34. Meanwhile, the top of the frame strip 3 is integrally formed with a protruding edge 35 above the sliding groove 34. The thickness of the protruding edge 35 is adapted to the slot size of the subsequent corner connector 4.

[0030] The corner connector 4 has symmetrically arranged protruding handles 41 at both ends. The size of the protruding handles 41 matches the guide groove 33 of the frame strip 3 and can slide along the guide groove 33. The bottom of the inner side of the protruding handles 41 is connected to a protruding strip 42 and the top is connected to a baffle 43. A third slot 44 is reserved between the protruding strip 42 and the baffle 43. The width of the third slot 44 is the same as the thickness of the protruding edge 35 of the frame strip 3.

[0031] Please read Figure 6-9 As shown, the steel mesh 1, insert 2, frame strip 3 and corner connector 4 are made of metal and are assembled into a whole steel mesh. The insert 2 extends through the steel mesh 1 to the front end of the opening of the first slot 31. The lower part of the insert 2 is provided with several protruding teeth, which abut against the edge of the first slot 31. This fixing method is very stable.

[0032] The assembly process is as follows:

[0033] First, align the plug 21 at the bottom of the insert 2 with the socket 11 on the edge of the steel mesh 1, insert it vertically downwards and lock it in place to complete the pre-connection between the steel mesh 1 and the insert 2. The point-to-point locking of the plug 21 and the socket 11 prevents the steel mesh 1 from shifting during subsequent assembly with the frame strip 3, while also enhancing the structural strength of the steel mesh edge and preventing it from deforming under stress.

[0034] Next, align the pre-connected steel mesh 1 edge and insert 2 with the first slot 31 and second slot 32 of the frame strip 3 respectively, and push them horizontally in along the opening direction on the same side of the first slot 31 and second slot 32 until the ends of the steel mesh 1 and insert 2 are in contact with the inner wall of the slot. At this time, the steel mesh 1 forms a double fixing structure with the frame strip 3 through the insert 2, which avoids wear caused by direct contact between the steel mesh 1 and the frame strip 3, and also disperses the force on the edge of the steel mesh through the insert 2.

[0035] Finally, align the protruding handles 41 at both ends of the corner connector 4 with the guide grooves 33 of the adjacent frame strips 3, and push the corner connector 4 along the guide grooves 33 until the protruding strip 42 on the inner side of the protruding handle 41 slides into the sliding groove 34 of the frame strip 3. At this time, the protruding edge 35 of the frame strip 3 is simultaneously engaged in the third slot 44 of the corner connector 4. The baffle 43 forms an axial limit on the protruding edge 35 to prevent the protruding edge 35 from coming out of the third slot 44. Through the triple engagement of the protruding handle 41 with the guide groove 33, the protruding strip 42 with the sliding groove 34, and the protruding edge 35 with the third slot 44, the adjacent frame strips 3 are stably connected, and finally a rectangular or other shaped frame is formed.

[0036] After completing the above three assembly steps, the steel mesh 1, insert 2, frame strip 3, and corner connector 4 form a complete rigid structure (as shown in Figures 4 and 5). The entire assembly process does not require the use of bolts, screws, or other fasteners. It relies entirely on the snap-fit ​​structure to achieve rapid fixation, which greatly improves assembly efficiency. At the same time, the detachable design of each component facilitates subsequent maintenance.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
