[0003] However, existing convenient and quick-installation trench formwork joint clamps have the following disadvantages:

[0004] (1) Traditional clamps often use a fixed connection method with the template body. When the connecting components are worn, deformed or broken due to long-term use, it is impossible to disassemble and replace a single damaged part.

[0005] (2) Some traditional clamps rely on the adhesion between the template liner and the pipe for auxiliary fixation. As the number of uses increases or environmental factors affect the situation, the adhesion is likely to gradually decrease, leading to the separation of the template liner and the pipe.

[0006] Therefore, this utility model provides a convenient and quick-installation trench template joint clamp. Utility Model Content

[0018] (III) Beneficial Effects

[0019] This utility model provides a convenient and quick-installation trench template joint clamp, which has the following advantages:

[0020] 1. This convenient and quick-installation trench template connector clamp, through the design of the disassembly components, allows for easy disassembly of the first and second connecting plates if either the first or second connecting plate is damaged after prolonged use. This is achieved by pressing the pressure plate, which causes the locking block to slide on the first insert rod and compresses the locking spring, thus avoiding the need to replace the entire pipe due to damage to the first or second connecting plate and reducing replacement costs.

[0021] 2. This convenient and quick-installation trench template joint clamp, through the setting of the fixing components, allows for the following usage: First, the splicing plate is inserted into another pipe. At the same time as insertion, the second insert rod and the clamping plate are inserted into the splicing plate. Then, the second insert rod is pressed to compress the fixing spring. After pressing all the way down, the second insert rod is rotated 90 degrees, and then released. The fixing spring returns to its original position, thereby driving the clamping plate to engage with the slot. This prevents the template lining from losing adhesion with the pipe, which could lead to separation of the template lining and the pipe, rendering the pipe unusable. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a convenient and quick-installation trench template joint clamp, including a pipe 1, a template liner 2 is glued to one side of the inner wall of the pipe 1, a reinforcing plate 3 is fixedly installed on the inner wall of the template liner 2, a disassembly component 4 is provided on one side of the reinforcing plate 3, and a fixing component 5 is provided on one side of the upper end of one of the pipes 1.

[0029] Disassembly assembly 4 includes a mounting block 401, a pressure plate 402, a locking block 403, a first insert rod 404, a locking spring 405, a first connecting plate 406, and a second connecting plate 407. The mounting block 401 is fixedly mounted on one side of the reinforcing plate 3. Pressure plates 402 are movably connected to both sides of the mounting block 401. A locking block 403 is movably connected to one side of the pressure plate 402. The first insert rod 404 is inserted into one side of the locking block 403. A locking spring 405 is sleeved on the surface of the first insert rod 404. One side of the locking spring 405 is fixedly mounted on... Installed on one side of the inner wall of the locking block 403, the disassembly component 4 is designed to allow the locking block 403 to slide on the first insert 404 and compress the locking spring 405 if either the first connecting plate 406 or the second connecting plate 407 is damaged after prolonged use. This allows the first connecting plate 406 and the second connecting plate 407 to be disassembled, thus avoiding the need to replace the entire pipe fitting 1 due to damage to the first connecting plate 406 and the second connecting plate 407, and reducing replacement costs.

[0030] The fixing component 5 includes a splicing rod 501, a second insert rod 502, a fixing spring 503, and a clamping plate 504. The splicing rod 501 is fixedly installed on one side of the upper end of one of the pipe fittings 1. The second insert rod 502 is inserted into one side of the splicing rod 501, and the second insert rod 502 is fixedly installed into the clamping plate 504 on one side. By setting up the fixing component 5, the splicing plate 6 can be inserted into the other pipe fitting 1 first. At the same time as insertion, the second insert rod 502 and the clamping plate 504 are inserted into the splicing plate 6. Then, the second insert rod 502 is pressed to compress the fixing spring 503. After pressing to the bottom, the second insert rod 502 is rotated 90 degrees and then released. The fixing spring 503 is then reset, which drives the clamping plate 504 to be clamped into the slot. This avoids the template liner 2 from losing adhesion with the pipe fitting 1, which would cause the template liner 2 to separate from the pipe fitting 1 and make the pipe fitting 1 unusable.

[0031] A fixing spring 503 is sleeved on the surface of the second insertion rod 502. The fixing spring 503 facilitates the engagement of the card plate 504 into the card slot. One end of the fixing spring 503 is fixedly installed on the inner wall of the splicing rod 501.

[0032] A splicing plate 6 is fixedly installed on one side of another pipe fitting 1. A socket is opened on one side of the splicing plate 6, and a slot is opened on the inner wall of the socket. The slot is designed to cooperate with the card plate 504 to install the two pipe fittings 1.

[0033] One of the first insertion rods 404 has a first connecting plate 406 fixedly installed on one side, and the other first insertion rod 404 has a second connecting plate 407 fixedly installed on one side. The second connecting plate 407 facilitates the use of the first connecting plate 406 to install the two pipe fittings 1.

[0034] The inner wall of the first connecting plate 406 is threaded with a connecting bolt 7, and a nut 8 is threaded on one side of the connecting bolt 7. The nut 8 is used to fix the first connecting plate 406 and the second connecting plate 407 in conjunction with the connecting bolt 7.

[0035] A first threaded hole is provided on one side of the upper end of the first connecting plate 406, and a second threaded hole is provided on one side of the upper end of the second connecting plate 407. The second threaded hole facilitates the installation of the connecting bolt 7.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: When using it, first insert the splicing plate 6 into another pipe 1. At the same time as inserting, insert the second rod 502 and the clamping plate 504 into the splicing plate 6. Then press the second rod 502 to compress the fixing spring 503. After pressing it all the way down, rotate the second rod 502 ninety degrees and then release it. The fixing spring 503 will then return to its original position and drive the clamping plate 504 to engage in the slot. This will prevent the template liner 2 from losing adhesion with the pipe 1, which would cause the template liner 2 to separate from the pipe 1 and make the pipe 1 unusable.

[0038] Second step: Finally, if either the first connecting plate 406 or the second connecting plate 407 is damaged after a long period of use, the pressure plate 402 can be pressed to drive the locking block 403 to slide on the first insert 404 and compress the locking spring 405, thereby disassembling the first connecting plate 406 and the second connecting plate 407. This avoids the need to replace the entire pipe fitting 1 due to damage to the first connecting plate 406 and the second connecting plate 407, thus reducing replacement costs.
