Of course, in practical applications, you can also only adjust the position of the limiting component 2 relative to the length direction or width direction of the installation mechanism 1, and adjust the position of the limiting component 2 according to the specific length and width of the air conditioning panel.

The mounting mechanism and limiting assembly of the present invention will be described below with reference to FIGS. 1 to 4 . Among them, Fig. 2 is a schematic diagram of the second state of the screen printing tooling of the present invention; Fig. 3 is a partial enlarged view of the M position in Fig. 2; Fig. 4 is a partial enlarged view of the N position in Fig. 2.

As shown in Figures 1 and 2, the installation mechanism 1 includes a base 11; the limiting component 2 includes two first limiting mechanisms, namely the first limiting mechanism A21 and the first limiting mechanism B22. The first limiting mechanism A21 and the first limiting mechanism B22 are respectively provided at the first end of the base 11 (that is, the end on the left side of the paper in Figure 1) and the second end of the base 11 along the length direction of the base 11 (ie, the direction from left to right in Figure 1). end (that is, the end on the right side of the paper in Figure 1), and the first limiting mechanism A21 and the first limiting mechanism B22 are slidingly connected to the base 11 respectively. The adjusting component 4 is connected to the first limiting mechanism A21 and the first limiting mechanism B22 respectively. The adjusting component 4 is used to adjust the positions of the first limiting mechanism A21 and the first limiting mechanism B22 along the length direction of the base 11, thereby adjusting The relative distance between the first limiting mechanism A21 and the first limiting mechanism B22 enables the silk screen printing tool to match air conditioning panels of different lengths or widths, and can more stably limit the air conditioning panel along the length or width direction of the air conditioning panel.

Among them, the first limiting mechanism A21 and the first limiting mechanism B22 have the same structure. The following will further elaborate on the first limiting mechanism A21 as an example.

As shown in FIG. 2 , the first limiting mechanism A21 includes a first fixed plate 211 and a plurality of first limiting posts 212 provided on the first fixed plate 211 , for example, 8, 11 or 14 other numbers. , after adjusting the position of the first limiting mechanism A21 relative to the base 11, the plurality of first limiting posts 212 can abut the wide edge of the air conditioning panel to define the first installation position of the air conditioning panel, that is, the air conditioning panel is along the base The installation position in the length direction of 11 can match air conditioning panels of different lengths.

Preferably, the first fixing plate 211 is provided with a plurality of first mounting holes 2111 matching the plurality of first limiting posts 212, and the connection end of each first limiting post 212 (ie, the bottom of the paper in Figure 2 one end) are respectively fixedly connected to the corresponding first mounting holes 2111.

Furthermore, the plurality of first limiting posts 212 are arranged at intervals along the length direction of the first fixing plate 211 (ie, the direction from the lower left to the upper right in FIG. 2 ), and may be arranged at equal intervals or at non-equal intervals.

As shown in Figures 1 and 2, two first sliding structures 213 are provided at the bottom of the first fixed plate 211 and along its length direction. Correspondingly, there are two first sliding structures 213 at the top of the base 11 along its width direction (ie, from the lower left in Figure 2 (to the upper right direction) are provided with two second sliding structures 12. The first sliding structure 213 and its corresponding second sliding structure 12 are slidingly connected to each other, thereby realizing the sliding connection between the first limiting mechanism A21 and the base 11. Of course, in practical applications, one, three or more first sliding structures 213 can also be provided at the bottom of the first fixed plate 211, and accordingly, one, three or more second sliding structures 213 can be provided at the top of the base 11. structure 12, those skilled in the art can flexibly adjust and set the number of the first sliding structure 213 and the second sliding structure 12.

As shown in Figure 3, the first sliding structure 213 includes a first sliding block 2131 formed on the bottom of the first fixed plate 211. The first sliding block 2131 is provided with a first slide groove 2132. The second sliding structure 12 includes a first sliding block 2131 formed on the base. The first slide rail 121 on the top of 11, the first slide groove 2132 and the first slide rail 121 are slidingly connected to each other.

Of course, the first sliding structure 213 and the second sliding structure 12 are not limited to the structures listed above. The first sliding structure 213 and the second sliding structure 12 can also be a structure in which a slide rail and a slide block cooperate, or a slide track and a slide rail. The matching structure, no matter what kind of sliding structure is adopted, is sufficient as long as the first limiting mechanism A21 and the base 11 can slide relative to each other.

As shown in Figures 1 and 2, the limiting assembly 2 also includes two second limiting mechanisms, namely the second limiting mechanism C23 and the second limiting mechanism D24, and the second limiting mechanism C23 and the second limiting mechanism D24. Mechanism D24 is respectively provided at the third end (i.e., the end on the inside of the paper in Figure 1 ) and the fourth end (i.e., the end on the inside of the paper in Figure 1 ) of the base 11 along the width direction of the base 11 (i.e., the direction from the inside to the outside in Figure 1 ). The outer end), and the second limiting mechanism C23 and the second limiting mechanism D24 are slidingly connected to the base 11 respectively. The adjusting component 4 is connected to the second limiting mechanism C23 and the second limiting mechanism D24 respectively. The adjusting component 4 is used to adjust the positions of the second limiting mechanism C23 and the second limiting mechanism D24 along the width direction of the base 11, thereby adjusting the second limiting mechanism C23 and the second limiting mechanism D24. The relative distance between the second limit mechanism C23 and the second limit mechanism D24 enables the silk screen printing tool to match air conditioning panels of different widths or lengths, and can more stably limit the air conditioning panel along the width or length direction of the air conditioning panel.

Among them, the second limiting mechanism C23 and the second limiting mechanism D24 have the same structure. The second limiting mechanism D24 will be further described below by taking the second limiting mechanism D24 as an example.

As shown in FIG. 2 , the second limiting mechanism D24 includes a second fixed plate 241 and a plurality of second limiting posts 242 provided on the second fixed plate 241 , for example, 15, 19, 23 or other numbers. , after adjusting the position of the second limiting mechanism D24 relative to the base 11, the plurality of second limiting posts 242 can abut the long sides of the air conditioning panel to define the second installation position of the air conditioning panel, that is, the air conditioning panel is along the base. The installation position in the width direction of the base 11, under the joint action of the first limiting column 212 and the second limiting column 242, can define the installation position of the air conditioning panel along the length direction and width direction of the base 11, and can match different lengths and Width air conditioning panel.

Preferably, the second fixing plate 241 is provided with a plurality of second mounting holes 2411 matching the plurality of second limiting posts 242, and the connection end of each first limiting post 212 (ie, the bottom of the paper in Figure 2 one end) are respectively fixedly connected to the corresponding second mounting holes 2411.

Furthermore, the plurality of second limiting posts 242 are arranged at intervals along the length direction of the second fixing plate 241 (ie, the direction from the upper left to the lower right in FIG. 2 ), and may be arranged at equal intervals or at non-equal intervals.

As shown in FIGS. 1 and 2 , two third sliding structures 243 are provided at the bottom of the second fixed plate 241 and along its length direction. Correspondingly, the top of the base 11 is provided along its length direction, that is, as shown in FIG. 2 . direction from upper left to lower right), two first mounting seats 13 are provided, and a fourth sliding structure 14 is installed on each first mounting seat 13. The third sliding structure 243 and the fourth sliding structure 14 are slidingly connected to each other, so that The sliding connection between the second limiting mechanism D24 and the base 11 is realized. Moreover, due to the provision of the first mounting base 13, the height of the second fixing plate 241 relative to the base 11 is greater than the height of the first fixing plate 211 relative to the base 11. There is a spatial avoidance between the two, which can be larger. Adjusting the positions of the first limiting mechanism A21 and the first limiting mechanism B22 relative to the base 11 to the maximum extent can match more sizes of air conditioning panels. Alternatively, the first mounting base 13 can also be disposed between the second sliding structure 12 and the base 11 , and the position of the first mounting base 13 can be adjusted no matter what, as long as the second fixing plate 241 and the first fixing plate 211 can interact with each other. Just avoid it.

Of course, in practical applications, one, three or more third sliding structures 243 can also be provided only at the bottom of the second fixed plate 241, and accordingly, one, three or more fourth sliding structures 243 can be provided at the top of the base 11. For the sliding structure 14, those skilled in the art can flexibly adjust and set the number of the third sliding structure 243 and the fourth sliding structure 14.

The second sliding block 2431 is provided with a second slide groove 2432 . The fourth sliding structure 14 includes a second sliding block 2431 formed on the bottom of the second fixing plate 241 . The second slide rail 141 on the top of the mounting base 13, the second slide groove 2432 and the second slide rail 141 are slidingly connected to each other.

Of course, the third sliding structure 243 and the fourth sliding structure 14 are not limited to the structures listed above. The third sliding structure 243 and the fourth sliding structure 14 can also be a structure in which a slide rail and a slide block cooperate, or a slide track and a slide rail. The matching structure, no matter what kind of sliding structure is adopted, is sufficient as long as the second limiting mechanism D24 and the base 11 can slide relative to each other.

Of course, in practical applications, the first limiting mechanism A21 and the first limiting mechanism B22 can also be respectively provided at the third end and the fourth end of the base 11 along the width direction of the base 11, and the second limiting mechanism C23 and the second limiting mechanism D24 are respectively arranged at the first end and the second end of the base 11 along the length direction of the base 11. Correspondingly, the adjusting assembly 4 is used to adjust the first limiting mechanism A21 and the first limiting mechanism B22 along the length direction. The width direction position of the base 11 , and adjusting the positions of the second limiting mechanism C23 and the second limiting mechanism D24 along the length direction of the base 11 .

Referring now to Figures 1 to 3, the adjustment assembly is used to adjust the positions of the first limiting mechanism A and the first limiting mechanism B along the length direction of the base, and to adjust the second limiting mechanism C and the second limiting mechanism D. Taking the position along the width direction of the base as an example, the adjustment assembly of the present invention will be described.

As shown in Figures 1 and 2, the adjustment assembly 4 includes a first adjustment mechanism 41 provided on the base 11, wherein the first adjustment mechanism 41 is connected to the first limiting mechanism A21 and the first limiting mechanism B22 respectively. An adjustment mechanism 41 is used to drive the first limiting mechanism A21 and the first limiting mechanism B22 to move relatively and away from each other along the length direction of the base 11, and can quickly adjust the relationship between the first limiting mechanism A21 and the first limiting mechanism B22. The relative distance allows the silk screen tooling to match air conditioning panels of different lengths and more stably define the air conditioning panel along its length.

For example, when the length of the air conditioning panel is greater than the current distance between the first limiting mechanism A21 and the first limiting mechanism B22, the first limiting mechanism A21 and the first limiting mechanism B22 are made to be opposite each other along the length direction of the base 11. back movement to increase the distance between the first limiting mechanism A21 and the first limiting mechanism B22; when the length of the air conditioning panel is less than the current distance between the first limiting mechanism A21 and the first limiting mechanism B22, Then the first limiting mechanism A21 and the first limiting mechanism B22 are relatively moved along the length direction of the base 11 to reduce the distance between the first limiting mechanism A21 and the first limiting mechanism B22; when the length of the air conditioning panel When it is substantially equal to the current distance between the first limiting mechanism A21 and the first limiting mechanism B22, the first limiting mechanism A21 and the first limiting mechanism B22 will not move relative to the base 11, and the first limiting mechanism will not be adjusted. The distance between A21 and the first limiting mechanism B22.

Among them, the first adjustment mechanism 41 is connected to the first fixed plate of the first limiting mechanism A21 and the first fixed plate of the first limiting mechanism B22 respectively, and the first adjusting mechanism 41 is used to drive the first fixing plate of the first limiting mechanism A21.
