[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a connection and locking device for a bridge template, comprising a template body 1, a support plate 2 is arranged on the outer surface of the template body 1, a first clamping strip 3 is fixedly connected to one side of the support plate 2, the outer surface of the first clamping strip 3 is clamped and connected with the inner wall of the first clamping groove 9, a clamping seat 4 is arranged at the bottom of the support plate 2, a slide groove is opened on the top of the clamping seat 4, the top of the clamping seat 4 is movably connected to the inner wall of the rotating groove 15 through the slide groove, a nut head 5 is fixedly connected to the top of the clamping seat 4, and the outer surface of the first clamping strip 3 is clamped and connected with the inner wall of the first clamping groove 9. A fixing strip 6 is fixedly connected to the outer surface, and the outer surface of the fixing strip 6 is snap-connected with the inner wall of the first slot 10. A first slot 9 is provided on the outer surface of the template body 1, and a first slot 10 is provided at the bottom of the first slot 9. A second slot 11 is provided on one side of the first slot 10. A second fixing strip 14 is fixedly connected to the outer surface of the support plate 2, and the outer surface of the second fixing strip 14 is snap-connected with the inner wall of the second slot 11. A rotating groove 15 is provided at the bottom of the support plate 2, and a snap-fit ​​opening 16 is provided on the outer surface of the base 4.

[0022] In this embodiment, the support plate 2 is designed to support the lower end structure and operate the lower end structure for fixed connection. The first card strip 3 is designed to engage with the first card slot 9. The first card strip 3 and the first card slot 9 are symmetrically arranged with two, which is convenient for simply connecting the upper and lower plastic templates. The second card strip 14 is designed to engage with the second card slot 11, which is convenient for simply connecting the left and right plastic templates. The first notch 10 is designed to facilitate the fixing strip 6 to be stuck in the first notch 10. The number of the first notches 10 is symmetrical and equidistantly distributed, and the number of the fixing strips 6 is set accordingly. When the card holder 4 is connected by the card slot, the fixing strip 6 can be easily connected to the card holder 4. When the joint 16 is inserted into the edge of the plastic template, one side of the engaging mouth 16 contacts the edge of the template, and the other side is away from the edge. At this time, the initial state of the fixing strip 6 is on the side away from the edge. At this time, by screwing the nut head 5, the holder 4 is rotated, driving the fixing strip 6 to rotate. The top of the fixing strip 6 is set as a circular curved surface, and the corresponding notches are also the same curved surface. Therefore, after rotating the tops of the four fixing strips 6, they are directly inserted into the four first notches 10. At this time, the fixing strip 6 cooperates with the four clamping strips to fix the top corners of the four template bodies 1. The operation is simple and does not require too many tools. When removing, just screw the nut head 5 in the opposite direction.

[0023] Example 2

[0024] like Figure 4 As shown, a fixing plate 7 is provided on the outer surface of the template body 1, a clamping block 8 is provided on the bottom of the fixing plate 7, a second slot 12 is provided on the inner wall of the template body 1, a third clamping slot 13 is provided on one side of the second slot 12, a spring 17 is fixedly connected to one side of the clamping block 8, a clamping column 18 is fixedly connected to the top of the spring 17, a top of the clamping column 18 is fixedly connected to one side of the fixing plate 7, an outer surface of the clamping column 18 is fixedly connected to the outer surface of the template body 1 through the clamping block 8, an inner wall of the second slot 12 is clamped and connected to the outer surface of the clamping block 8, and an inner wall of the third clamping slot 13 is clamped and connected to the outer surface of the clamping column 18.

[0025] In this embodiment, when installing the plastic template, the templates at the upper and lower ends only need to fix the left and right templates, so a second slot 12 and a third slot 13 are opened in the hollow grooves of the two templates. When the card column 18 on one side of the fixing plate 7 is inserted into the third slot 13, the spring 17 is compressed to cause the card block 8 to shrink in the slot and continue to be pressed down to the second slot 12. The card block 8 rebounds at the second slot 12, so that the left and right templates are fixed to prevent the upper and lower ends from being too loose.

[0026] Working principle:

[0027] like Figure 1-Figure 4 As shown, after the four templates are fitted together, the first clamping strip 3 is clamped with the first clamping slot 9, the second clamping strip 14 is clamped with the second clamping slot 11, and at the same time, one side of the clamping opening 16 is in contact with the edge of the groove of the template, and the other side is away from the edge. The nut head 5 is turned to rotate the base 4, driving the fixing strip 6 to rotate. The tops of the four fixing strips 6 are directly clamped into the four first slots 10. At this time, the fixing strip 6 cooperates with the four clamping strips to fix the top corners of the four template bodies 1. The templates at the upper and lower ends are inserted into the third clamping slot 13 through the clamping column 18 on one side of the fixing plate 7. The spring 17 is compressed to shrink the clamping block 8 in the clamping slot, and continue to press down to the second slot 12. The clamping block 8 rebounds at the second slot 12 to complete the fixation.
