[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1: Figures 1 to 10 As shown, an embodiment of the present invention is a construction template with adjustable internal space, including a base 1, a plurality of right-angle plates 2 are arranged above the base 1, and the plurality of right-angle plates 2 are connected by connecting seats 3. The plurality of right-angle plates 2 and the connecting seats 3 form a square, and a moving mechanism 4 is provided on the base 1. The moving mechanism 4 is used to drive the right-angle plates 2 to move so as to change the size of the square area formed by the right-angle plates 2; the moving mechanism 4 includes a mounting plate 41, and a plurality of fixed rails 42 are provided on the edge of the mounting plate 41. Push rods 43 are slidably connected in the fixed rails 42, and the push rods 43 are connected to the right-angle plates 2. A driving unit is provided on the mounting plate 41, and the driving unit is used to drive the plurality of push rods 43 to move. The driving unit includes a rotating shaft 47, and the rotating shaft 47 is rotatably connected to the base 1. The rotating shaft 47 and the mounting plate 41 are movably connected. A rotating rod 44 is fixedly connected to the shaft 47, and the rotating rod 44 is located in the mounting plate 41. Both ends of the rotating rod 44 are rotatably connected to the transmission rod 45, and the end of the transmission rod 45 away from the rotating rod 44 is rotatably connected to the movable frame 46, and the push rod 43 is slidably connected to the movable frame 46. A positioning groove is provided in the movable frame 46, and the push rod 43 is slidably connected to the positioning groove. The middle part of the rotating rod 44 is fixedly connected to the rotating shaft 47, and a fan-shaped plate 7 is fixedly connected to the inner wall of the right-angle plate 2. A plug rod 8 is inserted into the fan-shaped plate 7, and the plug rod 8 passes through the push rod 43. The movable plate 10 is fixedly connected to the right-angle plate 2, and the two ends of the connecting seat 3 are open. The movable plate 10 slides and extends into the opening of the connecting seat 3. A plurality of bevel plates are provided on the base 1, and the right-angle plate 2 is slidably connected to the bevel plate, and the interior of the right-angle plate 2 is a hollow structure.

[0033] The right-angle plate 2 and the connecting seat 3 cooperate to form a cavity of the construction template. A wall can be formed by pouring concrete into the cavity formed by the right-angle plate 2. The movable mechanism 4 is provided to drive each right-angle plate 2 to move, so that the right-angle plate 2 drives the movable plate 10 to slide in the connecting seat 3, thereby changing the size of the internal space enclosed by the right-angle plates 2. The driving unit provided can simultaneously drive multiple right-angle plates 2 to adjust their positions at the same time, thereby changing the size of the internal space of the construction template.

[0034] like Figures 3 and 4 As shown, the driving unit includes a rotating shaft 47, which is rotatably connected to the base 1, and the rotating shaft 47 is movably connected to the mounting plate 41. A rotating rod 44 is fixedly connected to the rotating shaft 47, and the rotating rod 44 is located in the mounting plate 41. Both ends of the rotating rod 44 are rotatably connected to the transmission rod 45, and the end of the transmission rod 45 away from the rotating rod 44 is rotatably connected to the moving frame 46, and the push rod 43 is slidably connected in the moving frame 46.

[0035] like Figures 4 and 5 As shown, a positioning groove is provided in the movable frame 46 , the push rod 43 is slidably connected to the positioning groove, and the middle portion of the rotating rod 44 is fixedly connected to the rotating shaft 47 .

[0036] like Figure 5 As shown, the drive unit also includes a driven bevel gear 401, which is fixedly connected to the end of the rotating shaft 47 and is located in the base 1. A connecting rod 403 is rotatably connected in the base 1, and a driving bevel gear 402 is fixedly connected to the connecting rod 403. The driven bevel gear 401 and the driving bevel gear 402 are meshed.

[0037] The action process of the moving mechanism 4 is to first rotate the connecting rod 403, thereby driving the active bevel gear 402 on the connecting rod 403 to rotate. Since the active bevel gear 402 is engaged with the driven bevel gear 401, the driven bevel gear 401 is driven to rotate, thereby driving the rotating shaft 47 fixedly connected to the driven bevel gear 401 to rotate, and then driving the rotating rod 44 on the rotating shaft 47 to rotate. The rotation of the rotating rod 44 further drives the transmission rod 45 to rotate, and the transmission rod 45 drives the moving frame 46 to move. The moving frame 46 further drives the push rod 43 slidably connected thereto to move, thereby finally driving the right angle plate 2 to move, thereby changing the size of the internal space formed by the entire right angle plate 2.

[0038] like Figures 5 and 6 As shown, a braking mechanism 5 is provided on the base 1, and the braking mechanism 5 is used to control the start and braking of the moving mechanism 4. The braking mechanism 5 includes a fixed chuck 51, and the fixed chuck 51 is fixedly connected to the connecting rod 403. A moving chuck 52 is slidably connected to the connecting rod 403, and the moving chuck 52 corresponds to the fixed chuck 51.

[0039] By moving the movable chuck 52 in the above technical solution, the movable chuck 52 and the fixed chuck 51 are matched, so that the teeth on the movable chuck 52 are engaged with the teeth on the fixed chuck 51, the connecting rod 403 can be stopped from rotating.

[0040] like Figures 5 and 6 As shown, the braking mechanism 5 also includes a connecting frame 53, which is fixedly connected to the movable chuck 52, and a trapezoidal plate 55 is slidably connected to the inner wall of the base 1, and the trapezoidal plate 55 and the connecting frame 53 are slidably connected. A card slot is provided on the connecting frame 53, and the trapezoidal plate 55 and the connecting frame 53 are slidably connected through the card slot. A threaded rod 57 is threadedly connected to the base 1, and one end of the threaded rod 57 extends into the base 1 and is rotatably connected to the trapezoidal plate 55, and the other end of the threaded rod 57 is fixedly extended to the outside of the base 1 and is fixedly connected to a turntable 58.

[0041] The braking mechanism 5 is used to position the moving mechanism 4. When the moving mechanism 4 drives the right-angle plate 2 to move to a specified position, that is, when the size formed between the right-angle plates 2 needs to be fixed, the moving mechanism 4 is fixed by the braking mechanism 5 to prevent the moving mechanism 4 from moving, thereby changing the size of the internal space formed by the right-angle plate 2.

[0042] The action process of the braking mechanism 5 is as follows: first, the turntable 58 is rotated, and the turntable 58 further drives the threaded rod 57 to rotate, and the threaded rod 57 further drives the trapezoidal plate 55 connected to it to move, so that the oblique side of the trapezoidal plate 55 squeezes the connecting frame 53, and the connecting frame 53 pushes the movable chuck 52 connected to it to move along the limiting groove 59 provided on the connecting rod 403, and finally cooperates with the fixed chuck 51 to finally fix the connecting rod 403, thereby achieving braking of the movable mechanism 4.

[0043] like Figures 5 and 6 As shown, a first spring 54 is sleeved on the connecting rod 403, and the first spring 54 is connected to the movable chuck 52. The first spring 54 is provided to stretch the movable chuck 52 so that it does not cooperate with the fixed chuck 51 under normal conditions. A limiting groove 59 is provided on the connecting rod 403, and the movable chuck 52 is slidably connected in the limiting groove 59. A strip groove 56 is provided on the interior of the base 1, and the trapezoidal plate 55 is slidably connected to the strip groove 56.

[0044] like Figures 7 and 8 As shown, a rotating mechanism 6 is provided on the base 1, and the rotating mechanism 6 is used to drive the connecting rod 403 to rotate. The rotating mechanism 6 includes a positioning seat 61, the positioning seat 61 and the base 1 are fixedly connected, the connecting rod 403 passes through the positioning seat 61, and a rocker rod 65 is fixedly connected to the connecting rod 403. The rocker rod 65 is located in the positioning seat 61, and an arc groove 62 is provided on the positioning seat 61. A moving rod 63 is fixedly connected to the rocker rod 65, and the moving rod 63 passes through the arc groove 62 and is threadedly connected to a nut 64.

[0045] The rotating mechanism 6 is used to control the rotation of the connecting rod 403. By toggling the moving rod 63 to rotate, the moving rod 63 further drives the rocker rod 65 to rotate in the positioning seat 61. The rocker rod 65 drives the connecting rod 403 fixed thereto to rotate. After moving to the appropriate position, the positioning of the moving rod 63 is completed by tightening the nut 64, and then the fixing of the connecting rod 403 is completed by the positioning of the moving rod 63.

[0046] Example 2: Figures 8 to 10 As shown, comparative example 1, another embodiment of the present invention is: a mounting mechanism 9 is provided between the right-angle plate 2 and the connecting seat 3, the mounting mechanism 9 is used to fix the connecting seat 3 and the right-angle plate 2, a fan-shaped plate 7 is fixedly connected to the inner wall of the right-angle plate 2, a plug-in rod 8 is inserted into the fan-shaped plate 7, the plug-in rod 8 passes through the push rod 43, the fan-shaped plate 7 is located above the push rod 43, and multiple fan-shaped plates 7 are located on the same vertical line. By cooperating with the arranged fan-shaped plate 7 and the plug-in rod 8, the push rod 43 and the right-angle plate 2 can be connected, and the right-angle plate 2 and the push rod 43 can be conveniently disassembled.

[0047] like Figure 2 、 Figure 10 As shown, the mounting mechanism 9 includes a square rail 91, which is fixedly connected to the right-angle plate 2, a limiting seat 93 fixedly connected to the connecting seat 3, a pull rod 92 slidably connected to the limiting seat 93, a connecting head 95 fixedly connected to the pull rod 92, a second spring 94 sleeved on the pull rod 92, and the two ends of the second spring 94 are respectively connected to the limiting seat 93 and the connecting head 95, a sliding rod 97 is slidably connected in the square rail 91, a square rod 96 is rotatably connected between the sliding rod 97 and the connecting head 95, a limiting rail 98 is set on the connecting seat 3, and the limiting rail 98 and the sliding rod 97 are slidably connected.

[0048] The provided mounting mechanism 9 is used to connect the connecting seat 3 and the right-angle plate 2, and it is very convenient to disassemble and install the connecting seat 3 and the right-angle plate 2 through the mounting mechanism 9. When disassembly is required, pull the pull rod 92. At this time, the pull rod 92 drives the connecting head 95 to move, and the connecting head 95 further drives the square rod 96 connected to it to rotate. As the square rod 96 rotates, the sliding rod 97 connected to it is driven to slide in the square rail 91. When the sliding rod 97 moves out of the square rail 91, the connecting seat 3 and the right-angle plate 2 can be separated.

[0049] Working principle: Before pouring, the right-angle plate 2 is placed above the base 1, and the bevel edges of the right-angle plate 2 and the base 1 slide. Then the right-angle plate 2 and the connecting seat 3 are installed together through the installation mechanism 9. Then the right-angle plate 2 is driven to move by the rotating mechanism 6 and the moving mechanism 4, so as to control the distance between each right-angle plate 2 according to the required internal space size. The braking mechanism 5 is used to position the moving mechanism 4. When the moving mechanism 4 drives the right-angle plate 2 to move to the appropriate position, the moving mechanism 4 is braked by the braking mechanism 5 to avoid movement when pouring the cavity inside the right-angle plate 2, which results in a size different from the required size. When demolding, the base 1, right-angle plate 2 and connecting seat 3 can be quickly disassembled through the cooperation of the installation mechanism 9, the fan-shaped plate 7 and the insertion rod 8.
