[0002] To enhance the decorative effect of electrical appliances, logos or patterns are often screen-printed on their panels. Before screen printing, the panel needs to be fixed on a screen printing fixture, and then the logo or pattern is screen-printed onto the panel.

[0003] In related technologies, a screen printing fixture includes a base, a support frame, support strips, and limiting strips. The support frame is mounted on the base, and the support strips and limiting strips are mounted on the support frame. Both the support strips and limiting strips extend vertically, and there are multiple support strips. The panel has a screen printing side and a fixed side opposite to the screen printing side, and the multiple support strips are used to support the fixed side of the panel. The multiple limiting strips surround the support strips and abut against the outer periphery of the panel to fix the panel to the screen printing fixture.

[0004] However, the positions of the support strips and limit strips on the support frame cannot be adjusted, which means that the screen printing fixture can only be adapted to panels of specific sizes, resulting in poor versatility of the screen printing fixture. Summary of the Invention

[0012] In the preferred embodiment of the above-mentioned screen printing fixture, multiple sliding members are provided, and the multiple sliding members are spaced apart along the second direction. The second adjusting rod passes through the corresponding first limiting hole of each sliding member.

[0013] In the preferred embodiment of the above-mentioned screen printing fixture, there are multiple support frames, and the multiple support frames are spaced apart on the sliding member along a third direction.

[0014] In the preferred embodiment of the above-mentioned screen printing fixture, at least one of the first support columns on the support frame near the end of the sliding member is provided with a clamping member. The clamping member is disposed at the end of the first support column away from the base. The end of the clamping member away from the base has a clamping portion. The clamping portion clamps a second support column. The axis of the second support column extends along the third direction. The end of the second support column away from the sliding member is bent away from the base to form a first stop column.

[0015] In the preferred technical solution of the above-mentioned screen printing fixture, the second support column is provided with a plurality of second limiting holes, the axis of the second limiting holes extends along the first direction, and the plurality of second limiting holes are spaced apart along the third direction; along the third direction, another first support column adjacent to the first support column where the clamping member is located is selectively inserted into the second limiting hole.

[0016] Those skilled in the art will understand that the screen printing fixture of this application embodiment includes a base, a support frame, a first support column, and a first adjustment mechanism. The support frame is disposed on the base, and the first support column extends along a first direction and passes through the support frame. The first adjustment mechanism is disposed on the support frame and has a first position and a second position.

[0040] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0041] Secondly, it should be noted that in the description of the embodiments of this application, the terms "inner" and "outer" and other terms indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of this application.

[0042] Furthermore, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The screen printing fixture in the related technology includes a base, a support frame, support strips, and limiting strips. The support frame is mounted on the base, and the support strips and limiting strips are mounted on the support frame. Both the support strips and limiting strips extend vertically, and there are multiple support strips. The panel has a screen printing side and a fixed side opposite to the screen printing side, and the multiple support strips are used to support the fixed side of the panel. The multiple limiting strips surround the support strips and abut against the outer periphery of the panel to fix the panel to the screen printing fixture.

[0045] However, the screen printing fixtures in related technologies are customized according to the specific panel size and appearance. The positions of the support strips and limit strips on the support frame in the customized screen printing fixture cannot be adjusted, which means that the screen printing fixture can only be adapted to specific panels, resulting in poor versatility of the screen printing fixture.

[0046] This embodiment provides a screen printing fixture. By allowing the first support column to move relative to the support frame along a first direction, the height of the first support column along the first direction can be adjusted, making the screen printing fixture adaptable to panels with various curvatures and increasing the versatility of the screen printing fixture.

[0047] The principles and features of the embodiments of this application are described below with reference to the accompanying drawings. The examples given are only used to explain the embodiments of this application and are not intended to limit the scope of the embodiments of this application.

[0048] refer to Figure 1 The screen printing fixture provided in this embodiment includes a base 10, a support frame 20, a first support column 30, and a first adjustment mechanism 40. The base 10 is placed on the ground or a horizontal plane. The support frame 20 is mounted on the base 10 and has a certain elasticity, allowing for elastic deformation. The first support column 30 passes through the support frame 20 along a first direction Z. There can be multiple first support columns 30, which can be spaced apart along a second direction Y on the support frame 20. The second direction Y is perpendicular to the first direction Z.

[0049] The panel 100 may have a screen-printed side and a fixed side opposite to the screen-printed side, and the top of the first support column 30 is used to support the fixed side of the panel 100.

[0050] The first adjustment mechanism 40 is disposed on the support frame 20. The first adjustment mechanism 40 has a first position and a second position. When the first adjustment mechanism 40 is in the first position, the support frame 20 and the first support column 30 are disengaged, so that the first support column 30 can move relative to the support frame 20 in the first direction Z, thereby adjusting the height of the top of the first support column 30.

[0051] When the first adjustment mechanism 40 is in the second position, the support frame 20 clamps the first support column 30, preventing the first support column 30 from moving relative to the support frame 20, thereby fixing the first support column 30 at a set height.

[0052] refer to Figure 2 In this embodiment, the screen printing fixture can adjust the height of the top of each first support column 30 according to the curvature of the panel 100 (when the panel 100 is a curved plate), so that the top of each first support column 30 can abut against the fixed side of the panel 100. Therefore, the screen printing fixture in this embodiment can be adapted to panels 100 of various specifications, increasing the versatility of the screen printing fixture.

[0053] In some embodiments, the first adjustment mechanism 40 may include a first adjustment rod 410 and a fastener 420. The first adjustment rod 410 is movably inserted through the support frame 20 along the second direction Y. The first adjustment rod 410 includes a first rod portion, a second rod portion, and a third rod portion. The first rod portion and the second rod portion extend outside the support frame 20, and the third rod portion is located between the first rod portion and the second rod portion, and is inserted through the support frame 20. The fastener 420 is used to adjust the distance between the end of the first rod portion near the second rod portion and the end of the second rod portion near the first rod portion, so that the support frame 20 either clamps the first support column 30 or disengages the support frame 20 from the first support column 30, thereby adjusting the height of the first support column 30 along the first direction Z.

[0054] In some implementations, the fastener 420 may include a fastening bolt, which may be threadedly connected to the second rod portion. The distance between the end of the first rod portion near the second rod portion and the end of the second rod portion near the first rod portion can be adjusted by adjusting the screwing position of the fastening bolt relative to the second rod portion. Specifically, when the first adjusting mechanism 40 is in the first position, the distance between the end of the fastening bolt near the first rod portion and the end of the first rod portion near the second rod portion is L1. At this time, the support frame 20 and the first support column 30 are disengaged, allowing the first support column 30 to move relative to the support frame 20 in the first direction Z. When the first adjusting mechanism 40 is in the second position, the distance between the end of the fastening bolt near the first rod portion and the end of the first rod portion near the second rod portion is L2, where L2 is less than L1. At this time, the support frame 20 is compressed by the fastening bolt, and the support frame 20 clamps the first support column 30 to fix the first support column 30 to the support frame 20.

[0055] refer to Figure 3 and Figure 4 In some implementations, the fastener 420 may include a stop cam 421, a hinge shaft 422, and a handle 423. The outer peripheral side of the stop cam 421 is provided with a groove extending circumferentially along the stop cam 421. The end of the second rod portion away from the first rod portion passes through the groove. The hinge shaft 422 passes through the stop cam 421 and the second rod portion, with its axis perpendicular to the axis of the second rod portion. The handle 423 is provided on the outer peripheral side of the stop cam 421, and the handle 423 faces away from the groove.

[0056] Rotating handle 423 causes the abutment cam 421 to rotate about the axis of hinge shaft 422. During the rotation of the abutment cam 421, the second rod moves relative to the abutment cam 421 along the extension direction of the slide groove. The outer peripheral side of the abutment cam 421 has a first abutment 4211 and a second abutment 4212. When the second rod is located at one end of the extension direction of the slide groove, the first abutment 4211 abuts against the support frame 20. At this time, the support frame 20 and the first support column 30 are disengaged, so that the first support column 30 can move relative to the support frame 20 in the first direction Z. When the second rod is located at the other end of the extension direction of the slide groove, the second abutment 4212 abuts against the support frame 20. The distance between the second abutment 4212 and the axis of hinge shaft 422 is greater than the distance between the first abutment 4211 and the axis of hinge shaft 422. At this time, the support frame 20 is pressed by the abutment cam 421, and the support frame 20 clamps the first support column 30 to fix the first support column 30 to the support frame 20.

[0057] In some embodiments, the base 10 may include a support 110 and a slider 120. The slider 120 extends along a third direction X, which is perpendicular to a first direction Z and also perpendicular to a second direction Y. The support 110 is supported at both ends of the slider 120 in its extending direction. A support frame 20 is slidably disposed on the slider 120. There may be multiple support frames 20, which are spaced apart along the third direction X on the slider 120. Each support frame 20 can slide relative to the slider 120 along the third direction X to adjust the gap between two adjacent support frames 20 and the total length of the multiple support frames 20 along the third direction X, so that the screen printing fixture can be adapted to various panels 100 of different lengths, increasing the versatility of the screen printing fixture. The length direction of the panel 100 is parallel to the third direction X.

[0058] In some implementations, the slider 120 may include a sliding plate (see reference). Figure 1 The sliding plate is perpendicular to the second direction Y.

[0059] In some other implementations, the slider 120 may include a sliding post that extends along a third direction X.

[0060] In some embodiments, there may be multiple sliders 120, which are spaced apart along the second direction Y. The support frame 20 is slidably mounted on the multiple sliders 120 to make the support frame 20 more stable when sliding, and the multiple sliders 120 provide better support for the support frame 20, making the support frame 20 less prone to tipping over.

[0061] The aforementioned slider 120 can be detachably connected to the support base 110, for example, referring to Figure 1 and Figure 2The support base 110 may be provided with multiple sets of snap-fit ​​notches 111 at its top end along the first direction Z. Each set of snap-fit ​​notches 111 may include multiple snap-fit ​​notches 111. The number of multiple snap-fit ​​notches 111 in each set of snap-fit ​​notches 111 may be the same as the number of sliding members 120. The multiple snap-fit ​​notches 111 in each set of snap-fit ​​notches 111 may be arranged at intervals along the second direction Y. The lengths of the multiple snap-fit ​​notches 111 in each set of snap-fit ​​notches 111 along the first direction Z are equal, so that when multiple sliding members 120 are respectively inserted into the multiple snap-fit ​​notches 111 in a set of snap-fit ​​notches 111, the top ends of the multiple sliding members 120 along the first direction Z are located in the same horizontal plane. The multiple sets of snap-fit ​​notches 111 have different lengths along the first direction Z, so that when the slider 120 is inserted into different sets of snap-fit ​​notches 111, the top of the slider 120 along the first direction Z is at different horizontal heights. This allows the height of the slider 120 along the first direction Z to be adjusted according to the size of the panel 100 and the requirements of screen printing, so as to adapt to the screen printing requirements of panels 100 of different sizes and improve the versatility of screen printing fixtures.

[0062] Multiple snap-fit ​​notches 111 in one set of snap-fit ​​notches 111 can be arranged alternately with multiple snap-fit ​​notches 111 in another set of snap-fit ​​notches 111 to reduce the total length of multiple sets of snap-fit ​​notches 111 along the second direction Y, thereby reducing the length of the screen printing fixture along the second direction Y. While ensuring that the height of the sliding part 120 is adjustable, the space occupied by the screen printing fixture is reduced.

[0063] refer to Figure 5 One end of the slider 120 along the third direction X can be connected to the support base 110 by a fixing bolt 112. The fixing bolt 112 can pass through the support base 110 and be connected to the slider 120. The other end of the slider 120 along the third direction X can be inserted into the snap-fit ​​notch 111. This can adjust the position of the slider 120 on the support base 110 and make it difficult for the slider 120 to detach from the support base 110, thus increasing the stability of the connection between the slider 120 and the support base 110.

[0064] In some embodiments, the slider 120 may be provided with a plurality of first limiting holes, the axis of the first limiting holes extending along the second direction Y, and the plurality of first limiting holes being spaced apart along the third direction X; the screen printing fixture may also include a second adjusting rod 50, the second adjusting rod 50 passing through the support frame 20 and a first limiting hole, so as to fix the support frame 20 to the slider 120, making it difficult for the support frame 20 to detach from the slider 120.

[0065] The second adjusting rod 50 can be detachably inserted into the support frame 20 and the first limiting hole. When adjusting the position of the support frame 20 along the third direction X, the second adjusting rod 50 is pulled out from the support frame 20 and the first limiting hole. Then the support frame 20 can be moved along the third direction X. After the position of the support frame 20 is adjusted, the second adjusting rod 50 is inserted into the support frame 20 and the first limiting hole to fix the position of the support frame 20. This prevents the support frame 20 from shifting when the screen printing fixture is fixing the panel 100, which would affect the fixing effect of the screen printing fixture on the panel 100.

[0066] In a configuration where there are multiple sliding members 120, the second adjusting rod 50, which passes through the support frame 20, also passes through the first limiting holes of multiple sliding members 120 to increase the connection strength between the support frame 20 and the sliding members 120.

[0067] One end of the second adjusting rod 50 can extend outside the support frame 20, and the outer diameter of one end of the second adjusting rod 50 can be larger than the outer diameter of the second adjusting rod 50 located inside the support frame 20, so that the second adjusting rod 50 extending outside the support frame 20 abuts against the side wall of the support frame 20. The other end of the second adjusting rod 50 can also extend outside the support frame 20, and a fastening bolt is connected to the other end of the second adjusting rod 50. The fastening bolt and the second adjusting rod 50 are threaded together to further fix the support frame 20 and the sliding member 120.

[0068] refer to Figure 3 and Figure 4 In some embodiments, at least one first support column 30 on the support frame 20 near the end of the slider 120 may be provided with a clamping member 310 at one end away from the base 10. The clamping member 310 has a clamping portion at one end away from the base 10, which clamps a second support column 60. The axis of the second support column 60 extends along a third direction X. The end of the second support column 60 away from the slider 120 is bent away from the base 10 to form a first stop column 610. The first stop column 610 may extend along a first direction Z. After the fixed side of the panel 100 is supported on the first support column 30, the circumferential side of the first stop column 610 abuts against the end faces of both ends of the panel 100 in the length direction to restrict the degree of freedom of the panel 100 along the third direction X.

[0069] The second support column 60 can support the fixed side of the panel 100. The second support column 60 can increase the contact area between the fixed side of the panel 100 and the screen printing fixture, so that the force on the panel 100 is more balanced, and the panel 100 is more stable and reliable after being fixed to the screen printing fixture.

[0070] Furthermore, the second support column 60 is provided with multiple second limiting holes. The axis of the second limiting holes extends along the first direction Z, and the multiple second limiting holes are spaced apart along the third direction X. The first support column 30 on another support frame 20 adjacent to the support frame 20 where the clamping member 310 is located passes through a second limiting hole. When the length of the second support column 60 along the third direction X is large, the clamping member 310 and the first support column 30 simultaneously support the second support column 60, making it less likely for the second support column 60 to tilt relative to the third direction X, thereby improving the stability of the screen printing fixture.

[0071] In some embodiments, along the second direction Y, the first support columns 30 located at both ends of the support frame 20 can be fixed on the end faces of both ends of the panel 100 in the width direction to restrict the degree of freedom of the panel 100 along the second direction Y, making it difficult for the panel 100 to move along the second direction Y, thereby improving the fixing effect of the screen printing fixture on the panel 100, wherein the width direction of the panel 100 is parallel to the second direction Y.

[0072] refer to Figure 1-3 and Figure 5 In some embodiments, a rotating sleeve 810 can be fitted onto the top of the first support column 30 located at both ends of the support frame 20 along the second direction Y. The axis of the rotating sleeve 810 extends along the first direction Z. The rotating sleeve 810 can rotate around the first support column 30. A connecting column 820 can be provided on the outer peripheral side of the rotating sleeve 810. The axis of the connecting column 820 can be perpendicular to the axis of the rotating sleeve 810. The end of the connecting column 820 away from the rotating sleeve 810 is bent away from the support frame 20 to form a second stop column 830. The axis of the second stop column 830 can extend along the first direction Z. After the panel 100 is placed on the first support column 30, the rotating sleeve 810 is rotated so that the second stop column 830 abuts against the end faces of both ends of the panel 100 in the width direction, so as to further restrict the degree of freedom of the panel 100 along the second direction Y, making it more difficult for the panel 100 to move along the second direction Y, and improving the fixing effect of the screen printing fixture on the panel 100.

[0073] In some embodiments, the top of a portion of the first support column 30 may also be fixed with a third support column 70 by a fastener 320. The extension direction of the third support column 70 may be perpendicular to the extension direction of the first support column 30. The third support column 70 may increase the contact area between the fixed side of the panel 100 and the screen printing fixture, making the support force on the panel 100 more balanced. After the panel 100 is fixed to the screen printing fixture, the panel 100 is more stable and reliable.

[0074] In summary, the screen printing fixture of this application embodiment includes a base 10, a support frame 20, a first support column 30, and a first adjustment mechanism 40. The support frame 20 is disposed on the base 10, and the first support column 30 passes through the support frame 20 along a first direction Z. The first adjustment mechanism 40 is disposed on the support frame 20 and has a first position and a second position. When the first adjustment mechanism 40 is in the first position, the support frame 20 and the first support column 30 are disengaged, so that the first support column 30 can move relative to the support frame 20 along the first direction Z. When the first adjustment mechanism 40 is in the second position, the support frame 20 clamps the first support column 30. Through the above configuration, the height of the top of each first support column 30 can be adjusted according to the curvature of the panel 100 (when the panel 100 is a curved plate), so that the top of each first support column 30 can abut against the fixed side of the panel 100, thereby adapting to various specifications of panels 100 and increasing the versatility of the screen printing fixture.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
