DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-6 The present application provides an aluminum film construction template fastening device, which comprises a first fastener 1, a second fastener 2, a third fastener 3 and a fourth fastener 4.

[0024] The first fastener 1 comprises a first square tube 11 and a first bent portion 12, which is bent and extends from one end of the first square tube 11 and forms a first limiting space.

[0025] The second fastener 2 comprises a second square tube 21 and a second bent portion 22, which is bent and extends from one end of the second square tube 21 and forms a second limiting space, one end of the second square tube 21 is inserted into the first limiting space and is in sliding connection with the first limiting space, thereby realizing the relative adjustment between the first fastener 1 and the second fastener 2.

[0026] The third fastener 3 comprises a third square tube 31 and a third bent portion 32, which is bent and extends from one end of the third square tube 31 and forms a third limiting space, one end of the third square tube 31 is inserted into the second limiting space and is in sliding connection with the second limiting space, thereby realizing the relative adjustment between the second fastener 2 and the third fastener 3.

[0027] The fourth fastener 4 comprises a fourth square tube 41 and a fourth bent portion 42, which is bent and extends from one end of the fourth square tube 41 and forms a fourth limiting space, one end of the fourth square tube 41 is inserted into the third limiting space and is in sliding connection with the third limiting space, thereby realizing the relative adjustment between the third fastener 3 and the fourth fastener 4.

[0028] In addition, one end of the first square tube 11 is inserted into the fourth limiting space and is in sliding connection with the fourth limiting space, thereby constituting a complete circulating adjustment structure.

[0029] The first bent portion 12, the second bent portion 22, the third bent portion 32 and the fourth bent portion 42 are respectively provided with a locking assembly 5, which is used for fixedly connecting adjacent fasteners. By adjusting the locking assembly 5, the first fastener 1, the second fastener 2, the third fastener 3 and the fourth fastener 4 can be locked at a specified position to form a locking space for fixing the aluminum template.

[0030] The size and shape of the locking space can be adjusted by adjusting the sliding positions between the fasteners to adapt to aluminum templates of different sizes and thus meet diversified construction needs. Through the above structure, the cooperation of the fasteners not only enables the rapid fixing of the aluminum template, but also enables the flexible adjustment of the fixing range according to actual needs, thereby improving the construction efficiency and the applicability of the device.

[0031] Specifically, the locking assembly 5 comprises a locking screw 51, a mounting block 52 and a locking block 53.

[0032] The first bending part 12, the second bending part 22, the third bending part 32 and the fourth bending part 42 are all tubular structures, and the mounting blocks 52 are fixedly arranged inside the first bending part 12, the second bending part 22, the third bending part 32 and the fourth bending part 42 respectively. The locking screw 51 penetrates through the mounting block 52 and is threadedly connected with the mounting block 52, and one end of the locking screw 51 extends into the first limiting space, the second limiting space, the third limiting space and the fourth limiting space, for adjusting the relative positions between the fasteners. The locking block 53 is connected with the locking screw 51 through a bearing or other rotary connecting member, so as to ensure that the locking screw 51 can rotate smoothly.

[0033] The first strip-shaped groove 13 is arranged on the first square tube 11, the second strip-shaped groove 23 is arranged on the second square tube 21, the third strip-shaped groove 33 is arranged on the third square tube 31, and the fourth strip-shaped groove 43 is arranged on the fourth square tube 41. The locking screw 51 penetrates through the first strip-shaped groove 13, the second strip-shaped groove 23, the third strip-shaped groove 33 and the fourth strip-shaped groove 43 respectively, so that the square tubes can be kept in sliding connection while providing a stable positioning path for locking.

[0034] Please refer to Figure 3 When the locking screw 51 is rotated, the locking block 53 will move upward along the thread direction. Taking the locking between the second square tube 21 and the first bending part 12 as an example, when the locking screw 51 is rotated, the locking block 53 will move upward until the outer wall of the second square tube 21 and the inner wall of the first bending part 12 are pressed tightly, so as to realize the stable connection between the two. The locking block 53 is in sliding connection with the inner wall of the second square tube 21, so as to ensure the smoothness of movement and the reliability of fastening effect during adjustment.

[0035] In addition, the design of the first strip-shaped groove 13, the second strip-shaped groove 23, the third strip-shaped groove 33 and the fourth strip-shaped groove 43 provides a moving space for the locking screw 51, so as to ensure that the first fastener 1, the second fastener 2, the third fastener 3 and the fourth fastener 4 can realize relative sliding, thereby facilitating the adjustment of the size and shape of the locking space to adapt to aluminum templates of different specifications. By adjusting the locking assembly 5, the user can quickly realize the fixation of the aluminum template, and flexibly adjust the size and shape of the locking device according to the construction requirements.

[0036] Specifically, the locking block 53 is provided with a clamping tooth, and the shape of the clamping tooth is designed to be matched with the rack 6, for enhancing the fixation effect of the locking device. The inner walls of the first square tube 11, the second square tube 21, the third square tube 31 and the fourth square tube 41 are respectively provided with the rack 6, and the rack 6 is arranged along the axial direction of the square tube and is in engagement with the clamping tooth of the locking block 53. Through the engagement between the clamping tooth and the rack 6, the relative sliding between the fasteners can be effectively prevented, so as to improve the locking stability and carrying capacity of the device.

[0037] In use, when the locking screw 51 drives the locking block 53 to move to the predetermined position, the teeth will engage with the rack 6 at the corresponding position, ensuring that the locking block 53 is in a stable state. The arrangement of the rack 6 enables the locking device to be adapted to aluminum formworks of various sizes, further improving the applicability and flexibility of the fastening device.

[0038] In addition, the first square tube 11, the second square tube 21, the third square tube 31 and the fourth square tube 41 are respectively slidably installed with reinforcing plates 7. The reinforcing plates 7 have an outer shape matching the cross section of the square tubes and are slidably connected with the square tubes through guide rails or sliding grooves. The sliding installation design of the reinforcing plates 7 can further compress the aluminum formwork after the locking device is fixed, thereby enhancing the stability of the formwork and preventing loosening due to external vibration or impact.

[0039] In specific operation, the reinforcing plates 7 can be slid to the target position along the length direction of the square tubes as needed and are fixed through the locking assembly 5. This design not only facilitates operation but also provides additional reinforcing support in various construction scenarios, ensuring the stability of the aluminum formwork in high-strength construction.

[0040] It should be noted that in this text, relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
