Description

Technical Field

[0001] This utility model belongs to the field of simple clamp technology, specifically a simple clamp for an internal filtration device for pipelines. Background Technology

[0002] To ensure water quality, water pipelines are usually equipped with filters to remove impurities from the water passing through them. These filters are typically installed by pre-drilling holes inside the pipeline and then securing them with bolts.

[0003] For piping systems requiring temporary maintenance or frequent filter replacement, the above installation method results in slow disassembly and assembly of the filter device, and also requires the use of tools such as wrenches, leading to low efficiency. Therefore, a simple clamp for the internal filter device of the pipeline is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a simple clamp for an internal filtration device in a pipeline is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a simple clamp for an internal pipe filtration device, comprising an installation block; a fixing pipe is fixedly connected to one side of the outer wall of the installation block;

[0006] The fixed tube is equipped with a positioning mechanism, which includes a fixing ring fixedly connected to the inner wall of the fixed tube, a positioning rod slidably connected inside the fixed tube, a positioning block fixedly connected to one end of the positioning rod, and a limit block fixedly connected to the other end of the positioning rod extending out of the fixed tube. An extension groove is opened on one side of the limit block, an extension block is slidably connected inside the extension groove, and a fixing block is fixedly connected to one end of the extension block extending out of the extension groove. With the setting of the positioning mechanism, the filtration device can be quickly assembled and disassembled, and it is compatible with different pipe diameters and filter element types.

[0007] Preferably, an abutment block is fixedly connected to one side of the outer wall of the positioning rod, and the end of the abutment block away from the positioning rod is set as a semi-circle. By setting the abutment block, the limiting ability of the filter device, i.e. the filter element, can be enhanced.

[0008] Preferably, one end of the positioning block is elastically connected to one side of the fixing ring via a spring. The positioning block is square, and the spring allows the limiting block and the positioning rod to automatically reset under the pressure of the spring after being pulled.

[0009] Preferably, the side of the extension block away from the fixed block has a threaded hole, and a lead screw is threaded into the threaded hole. The other end of the lead screw is rotatably connected to the inner wall of the extension groove through a transmission ring. A transmission rod is fixedly connected to the side of the lead screw near the transmission ring. The other end of the transmission rod passes through the limiting block. By setting the lead screw, threaded hole and transmission rod, the moving distance of the extension block can be accurately controlled, and the filter device can be limited.

[0010] Preferably, a knob is fixedly connected to one end of the transmission rod located on the outside. A sealing rubber ring is provided on the side of the knob near the fixed tube. The knob allows the transmission rod to rotate easily by rotating the knob, and the sealing rubber ring enhances the sealing between the knob and the limiting block.

[0011] Preferably, a sealing ring is provided on the inner wall of the extension groove, and an auxiliary block is fixedly connected to one side of the outer wall of the positioning rod. By providing a sealing ring on the inner wall of the extension groove, the sealing performance is enhanced, preventing water or other liquids from entering the extension groove. By providing an auxiliary block, after the filter device is fixed in the pipe by the clamp, the position of the knob can be blocked to prevent water flow from impacting the knob and causing it to rotate.

[0012] Preferably, the inner wall of the fixing ring is provided with a sealing rubber ring, and the outer wall of the mounting block is provided with anti-slip texture. The sealing performance is improved by providing a sealing rubber ring on the inner wall of the fixing ring to prevent water from entering the fixing pipe through the fixing ring, and the anti-slip texture on the outer wall of the mounting block prevents slippage when the mounting block is pulled.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a simple clamp for an internal pipe filter device. Through the positioning mechanism, in conjunction with a fixing block and a fixing pipe, the filter device can be quickly assembled and disassembled. It is compatible with different pipe diameters and filter element types. Rotating the knob drives the screw to rotate, causing the extension block to move to a specified distance, pulling one or two adjacent limiting blocks away from the mounting block. The filter device is placed between the three limiting blocks, centered on the mounting block. Releasing the limiting blocks allows them to fit against the outside. Reversing the knob drives the screw to rotate, causing one end of the filter device to abut against the abutment block and the other end against the fixing block, thus clamping the filter device. Placing this clamping device into the pipe with the pre-cut fitting groove allows for tool-free fixing or removal of the filter element, resulting in high assembly and disassembly efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides a simple clamp for an internal filter device in a pipeline, including a circular mounting block 1. The outer wall of the mounting block 1 is provided with anti-slip texture to prevent slippage when the mounting block 1 is pulled.

[0025] Three fixed tubes 2 are fixedly connected to one side of the outer wall of the mounting block 1, which are arranged in a ring and are equidistant from the mounting block 1.

[0026] A positioning mechanism 3 is provided on the fixed pipe 2. The positioning mechanism 3 includes a circular fixing ring 31 fixedly connected to the inner wall of the fixed pipe 2. A sealing rubber ring is provided on the inner wall of the fixing ring 31 to improve the sealing performance and prevent water from entering the fixed pipe 2 through the fixing ring 31.

[0027] A cylindrical positioning rod 32 is slidably connected inside the fixed tube 2. One end of the positioning rod 32 is fixedly connected to a positioning block 33. The positioning block 33 limits the movement of the positioning rod 32 so that the positioning rod 32 will not completely detach from the fixed tube 2.

[0028] One end of the positioning block 33 is elastically connected to one side of the fixing ring 31 via a spring 5. The positioning block 33 is square. With the spring 5, the positioning block 33 can automatically drive the positioning rod 32 to automatically reset under the pressure of the spring 5 after the positioning rod 32 is pulled.

[0029] The other end of the positioning rod 32 extends out of the fixing tube 2 and is fixedly connected to a cylindrical limiting block 34. An extension groove 36 is provided on one side of the limiting block 34.

[0030] A rectangular extension block 37 is slidably connected inside the extension groove 36. One end of the extension block 37 extends out of the extension groove 36 and is fixedly connected to a rectangular fixing block 35.

[0031] The extension block 37 has a threaded hole 6 on the side away from the fixed block 35. A lead screw 7 is internally threaded into the threaded hole 6. The other end of the lead screw 7 is rotatably connected to the inner wall of the extension groove 36 through a transmission ring. A transmission rod 8 is fixedly connected to the side of the lead screw 7 near the transmission ring. The other end of the transmission rod 8 passes through the limiting block 34.

[0032] A knob 9 is fixedly connected to one end of the transmission rod 8 located on the outside. A sealing rubber ring is provided on the side of the knob 9 near the fixed tube 2. The transmission rod 8 can be rotated by rotating the knob 9. The sealing rubber ring can enhance the sealing between the knob 9 and the limit block 34.

[0033] The screw 7, threaded hole 6 and transmission rod 8 are designed to facilitate precise control of the movement distance of the extension block 37 and to facilitate the limiting of the filter device.

[0034] With the cooperation of the limiting block 34, the fixing block 35 and the fixing tube 2, the filter device can be easily limited between the fixing tube 2 and the fixing block 35 to clamp and fix the filter device, i.e. the filter element.

[0035] A stop block 4 is fixedly connected to one side of the outer wall of the positioning rod 32. The end of the stop block 4 away from the positioning rod 32 is set as a semi-circle. Through the stop block 4, the mounting block 1 will not be overly fitted with the filter device, thus affecting the filtration work of the filter device, and strengthening the ability to limit the position of the filter device, i.e. the filter element.

[0036] The inner wall of the extension groove 36 is provided with a sealing ring to enhance the sealing performance and prevent water or other liquids from entering the extension groove 36. An auxiliary block 10 is fixedly connected to one side of the outer wall of the positioning rod 32. After the filter device is fixed in the pipe by the clamp, the position of the knob 9 can be blocked by the auxiliary block 10 to prevent water flow from impacting the knob 9 and causing it to rotate.

[0037] Based on the above structure, the present invention includes the following implementation process:

[0038] Before installing the filter device, remove the flanges of the pipes that need to be installed with the filter device, and remove the adjacent pipes. The filter device can be a filter screen, filter element, dirt remover, etc.

[0039] Using a grooving tool, three sets of fitting grooves are pre-cut on the inner wall of the pipe to match the three limiting blocks 34 and are distributed in a ring at equal intervals. The grooving depth is the total length of the filter device together with the fixture after it is installed inside the fixture.

[0040] Rotating knob 9 drives lead screw 7 to rotate, and lead screw 7 gradually rotates out of threaded hole 6, driving extension block 37 to gradually move out of extension groove 36, so that extension block 37 moves to a specified distance, that is, the distance between fixed block 35 and mounting block 1 should be greater than the length of filter device.

[0041] Pull one or two adjacent limiting blocks 34 to move away from the mounting block 1, leaving enough space between the three limiting blocks 34 to place the filter device, place the filter device between the three limiting blocks 34 and center it with the mounting block 1 as the center, release the limiting blocks 34, and under the pressure of the spring 5, the positioning block 33 drives the limiting block 34 to reset through the positioning rod 32, so that the limiting block 34 fits against the outside;

[0042] The reverse knob 9 drives the lead screw 7 to rotate, causing the extension block 37 to gradually move back to the extension groove 36. The extension block 37 drives the fixed block 38 to move, and the fixed block 35 approaches and abuts against one end of the filter device, so that one end of the filter device abuts against the abutting block 4 and the other end abuts against the fixed block 35, thereby clamping the filter device.

[0043] Place the clamping fixture of the filter device into the pipe with the opening of the fitting groove. The limiting block 34 needs to be inserted into the fitting groove accordingly. The positioning rod 32 and the limiting block 34 should be fixed in the pipe so that they can no longer move. The installation of the filter device and the clamping fixture is completed. It should be noted that at this time, one side of the fixing block 35 should abut against the inner wall of the fitting groove, and one end of the knob 9 should be parallel to the end face of the water pipe and at the same level.

[0044] Place the adjacent pipe back into the position corresponding to the pipe of the filter device, and fix the two pipe sections together by flange or other fixing methods. The fixed pipe covers the limit block 34 and knob 9, so it will not affect the normal use of the filter device.

[0045] The above describes the installation of this fixture and the installation method and operation steps for the filter device;

[0046] When the filter needs to be removed for cleaning and replacement, reverse the above steps, remove the adjacent pipe, pull out the clamp, and directly pull the limit block 34 to remove the filter for replacement. After the replacement is completed, reinstall the filter back into the pipe according to the above installation steps.

[0047] The position of the fixing block 35 is set and does not need to be adjusted. Unless the filter device is replaced with a different specification or length, it is necessary to perform the above steps on the lead screw 7 to adjust the distance between the fixing block 35 and the mounting block 1.

[0048] The positioning mechanism 3, together with the fixing block 35 and the fixing pipe 2, can quickly complete the assembly and disassembly of the filter device. It is compatible with different pipe diameters and filter element types. It should be noted that this clamp is suitable for pipes with an inner diameter greater than 80mm and filter devices with a diameter greater than 80mm. The inner wall of the pipe should be the set value, that is, it needs to have sufficient wall thickness to open the fitting groove.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
