Description

Technical Field

[0001] This utility model relates to the field of polyolefin pipe cutting technology, specifically a polyolefin pipe cutting support frame. Background Technology

[0002] Polyolefins are a common type of plastic material, including polyethylene (PE) and polypropylene (PP), which are widely used in water pipes, gas pipes, and other applications. Polyolefin pipes are relatively long, and they need to be cut to the required length using a cutting device. Therefore, a polyolefin pipe cutting support frame is required when cutting them.

[0003] When cutting polyolefin pipes at the construction site, a workbench is generally used to clamp the polyolefin pipe, and then a cutting blade is used to cut it. However, the workbench is large and inconvenient to carry. Currently, most workers simply place the polyolefin pipe directly on the table, press it down by hand, and then cut it. This easily causes the cut surface to be non-perpendicular to the edge of the polyolefin pipe, resulting in a tilted cut surface, material waste, and increased construction costs. Therefore, it is necessary to improve the polyolefin pipe cutting support frame to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a polyolefin pipe cutting support frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyolefin pipe cutting support frame, comprising a first fixing plate and a second fixing plate, wherein a connecting frame is rotatably installed inside the adjacent ends of the first fixing plate and the second fixing plate, and a bidirectional threaded rod is rotatably installed inside the first fixing plate and the second fixing plate, wherein two sliders are threadedly installed on the outside of the two bidirectional threaded rods, a rubber sleeve is fixedly installed inside the slider, a fixing rod is inserted into the inside of the rubber sleeve, and a rotating cylinder is rotatably installed on the outside of the fixing rod.

[0006] Preferably, the rotating cylinder is located on top of the slider, and the four sliders are symmetrically slidably installed in pairs inside the fixed plate one or the fixed plate two.

[0007] Preferably, a damping pad is provided between the two bidirectional threaded rods and the first or second fixed plate.

[0008] Preferably, a rotating plate is rotatably mounted inside the fixing plate, a spring is fixedly mounted on the front side of the rotating plate, and a positioning post is fixedly mounted on the end of the spring away from the rotating plate.

[0009] Preferably, the positioning post is inserted into the interior of the fixed plate 2 through the rotating plate, and the fixed plate 1 has placement holes at the corresponding positions of the positioning post, and the spring is initially in a compressed state.

[0010] Preferably, the second fixing plate has a cutting groove inside, the first fixing plate has a storage groove inside, and magnetic blocks are fixedly installed inside both the first fixing plate and the second fixing plate.

[0011] Preferably, the top magnetic poles of the two magnetic blocks are opposite.

[0012] Compared with the prior art, the present invention provides a polyolefin pipe cutting support frame, which has the following advantages:

[0013] 1. This polyolefin pipe cutting support frame stores the fixing rod and rotating cylinder through the storage slot. Then, the second fixing plate is flipped to the left and placed on top of the first fixing plate. Under the action of two magnetic blocks, the fixing plate and rotating cylinder are folded and stored. The device is small in size after storage, making it easy to carry to the construction site for use.

[0014] 2. Based on this, the present invention uses four rotating cylinders to abut against the outside of the polyolefin tube, thereby completing the horizontal placement of the polyolefin tube and completing the positioning, avoiding the tilting of the cutting surface caused by improper placement during cutting, resulting in higher cutting accuracy and less material waste.

[0015] 3. Based on this, the present invention uses a cutting groove to prevent operational errors from damaging the second fixing plate during cutting, thus extending the service life of the device. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1:

[0026] Please see Figure 1-5 This utility model provides a technical solution: a polyolefin pipe cutting support frame, including a first fixing plate 1 and a second fixing plate 2. A connecting frame 3 is rotatably installed inside the adjacent ends of the first fixing plate 1 and the second fixing plate 2. A bidirectional threaded rod 4 is rotatably installed inside the first fixing plate 1 and the second fixing plate 2. Two sliders 5 are threadedly installed on the outside of the two bidirectional threaded rods 4. A rubber sleeve 6 is fixedly installed inside the slider 5. A fixing rod 7 is inserted into the inside of the rubber sleeve 6. A rotating cylinder 8 is rotatably installed on the outside of the fixing rod 7. The rotating cylinder 8 rotates outside the fixing rod 7, so that the rotating cylinder 8 limits the movement of the polyolefin pipe without restricting the movement of the polyolefin pipe.

[0027] Furthermore, the rotating cylinder 8 is positioned on top of the slider 5, and the four sliders 5 are symmetrically slidably installed in pairs inside the fixed plate 1 or the fixed plate 2, causing the rotating cylinder 8 to abut against the outside of the polyolefin tube.

[0028] Furthermore, damping pads are provided between the two bidirectional threaded rods 4 and the fixing plate 1 or fixing plate 2, so that the bidirectional threaded rods 4 can self-lock after rotation and will not rotate without external force, thus continuously limiting and fixing the polyolefin tube.

[0029] Furthermore, a rotating plate 9 is rotatably installed inside the fixed plate 1. A spring 10 is fixedly installed on the front of the rotating plate 9. A positioning post 11 is fixedly installed at the end of the spring 10 away from the rotating plate 9. The positioning post 11 is inserted into the inside of the fixed plate 2, so that the fixed plate 1 and the fixed plate 2 are positioned after being laid flat.

[0030] Furthermore, the positioning post 11 penetrates the rotating plate 9 and is inserted into the interior of the second fixing plate 2. The first fixing plate 1 and the positioning post 11 are provided with placement holes at corresponding positions. The spring 10 is initially in a compressed state. The spring 10 drives the positioning post 11 to be inserted into the interior of the second fixing plate 2, so that the first fixing plate 1 and the second fixing plate 2 are laid flat and positioned, which facilitates the placement of the polyolefin tube.

[0031] Example 2:

[0032] Please see Figure 3 Furthermore, in conjunction with Embodiment 1, it is further found that the interior of the second fixing plate 2 is provided with a cutting groove 12, the interior of the first fixing plate 1 is provided with a storage groove 13, and magnetic blocks 14 are fixedly installed inside both the first fixing plate 1 and the second fixing plate 2, so as to facilitate the folding and storage of the first fixing plate 1 and the second fixing plate 2.

[0033] Furthermore, the top magnetic poles of the two magnetic blocks 14 are opposite, and the magnetic blocks 14 inside the fixing plate 1 and the fixing plate 2 attract each other, so that while storing the fixing rod 7 and the rotating cylinder 8, the device is compact and easy to carry to the construction site for use.

[0034] In actual operation, both the fixing rod 7 and the rotating cylinder 8 are loaded inside the storage slot 13. Then, the fixing plate 2 is flipped to the left and placed on top of the fixing plate 1. At this time, the magnetic block 14 inside the fixing plate 1 and the fixing plate 2 attracts each other, so that the fixing rod 7 and the rotating cylinder 8 can be stored. The device is small and easy to carry to the construction site for use.

[0035] When needed, unfold the device and lay it flat on the ground. Pull the positioning pin 11 out of the placement hole in the fixing plate 1, then rotate it 180 degrees clockwise to release the positioning pin 11. At this time, the spring 10 rebounds and drives the positioning pin 11 to insert into the fixing plate 2, so that the fixing plate 1 and fixing plate 2 are laid flat for positioning, which facilitates the placement of the polyolefin tube. After the polyolefin tube is placed between the four fixing rods 7 at the top of the fixing plate 1 and fixing plate 2, rotate the bidirectional threaded rod 4 to drive the two sliders 5 to slide synchronously in opposite directions inside the fixing plate 1, so that the four rotating cylinders 8 are evenly... The tube is placed against the outside of the polyolefin tube, thus allowing the polyolefin tube to be placed horizontally and limited, preventing the cut surface from tilting due to improper placement during cutting. Then, the polyolefin tube is pushed to move on top of the fixing plate 1 and the fixing plate 2. The rotating cylinder 8 rotates outside the fixing rod 7, so that the rotating cylinder 8 limits the movement of the polyolefin tube without restricting its movement. When the cutting point marked on the polyolefin tube is above the cutting groove 12, the movement stops. The left hand presses on the top of the polyolefin tube, and the right hand holds the cutting machine to cut the polyolefin tube, thus completing the cutting of the polyolefin tube.

[0036] Furthermore, the fixed plate 2 has a cutting groove 12 inside, which prevents damage to the fixed plate 2 during cutting, expands the scope of operational errors, and extends the service life of the device.

[0037] Furthermore, a damping pad is provided between the bidirectional threaded rod 4 and the fixing plate 1 or the fixing plate 2, so that the bidirectional threaded rod 4 can self-lock after rotation and will not rotate without external force, thereby continuously limiting and fixing the polyolefin tube.

[0038] Furthermore, the fixing rod 7 and the slider 5 are installed through the rubber sleeve 6, making the installation of the fixing rod 7 faster and more convenient, and its use more flexible and labor-saving.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used merely 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. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
