Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to a plastic pipe cutting device. Background Technology

[0002] Plastic pipes are tubular materials made from high-molecular plastics through extrusion molding, and are widely used in water supply and drainage, HVAC, and other fields. During construction, due to the need for pipe length adaptation, interface connection, or layout adjustment, they must be cut to precise dimensions to ensure installation fit and system operating efficiency.

[0003] In existing pipe cutting technologies, two relatively movable arc-shaped clamping plates are typically used to clamp and fix the pipe. However, since the arc-shaped clamping plates are directly fixed to the drive source, their size and shape are predetermined. They cannot be flexibly replaced or adjusted according to the different diameters of the pipes in actual situations. This results in the device being unable to meet the needs of cutting different specifications of pipes in actual construction, reducing the overall applicability of the device. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, the clamping plate cannot be flexibly replaced or adjusted according to the different diameters of the pipes under actual conditions, which leads to the device being unable to meet the needs of cutting pipes of different specifications in actual construction and reducing the overall applicability of the device. Therefore, a plastic pipe cutting device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plastic pipe cutting device includes a base and a cutting assembly disposed above the base. A fixing chamber is fixedly connected to the top of the base, and the cutting assembly is installed on the fixing chamber. A sliding opening is provided on the fixing chamber, and a lower fixing strip and an upper fixing strip are vertically slidably inserted into the sliding opening. A through opening is provided on the fixing chamber.

[0007] Also includes:

[0008] A limiting component is used to limit and fix the upper fixing strip.

[0009] Preferably, multiple limiting grooves are provided on the opposite sidewalls of the upper fixing strip and the lower fixing strip.

[0010] Preferably, the limiting component includes an L-shaped plate that is vertically slidably connected within the opening, a screw that is rotatably connected to the top of the L-shaped plate and threadedly connected to the fixing chamber, a pull rod that is horizontally slidably connected to the L-shaped plate, baffles that are fixedly connected to the opposite ends of the two pull rods, a spring that is sleeved on the pull rod and the two ends of the spring that are fixedly connected to the L-shaped plate and the baffles respectively.

[0011] Preferably, the bottom surface of the baffle and the top surface of the upper fixing strip are in contact.

[0012] Preferably, the L-shaped plate has a limiting opening to facilitate the horizontal sliding of the pull rod, and the limiting opening is rectangular.

[0013] Preferably, the end of the screw away from the L-shaped plate is fixedly connected to a screw block that facilitates the operator to rotate the screw.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] This invention, through the setting of the limiting component, allows the operator to simply place the pipe on the opposite side of the matching upper and lower fixing bars when cutting pipes of different diameters and sizes. After the pipe is placed in place, the upper fixing bar is fixed by the synergistic action of the pull rod and the thread, so that the pipe is stably constrained both vertically and horizontally, thereby achieving stable clamping of pipes of different diameters, thus improving the applicability of the device and enabling it to meet the cutting needs of different pipes.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A plastic pipe cutting device includes a base 1 and a cutting assembly 3 mounted on top of the base 1. The base 1 has excellent load-bearing capacity, ensuring the device remains stable in complex and changing construction environments, preventing easy shaking or displacement, thus creating a safe and reliable operating platform for pipe cutting operations. A fixing chamber 2 is fixedly connected to the top of the base 1. The fixing chamber 2 not only provides a stable installation position for the cutting assembly 3 and the pipe, but also collects the cutting debris. The cutting assembly 3 is mounted on the fixing chamber 2, which has a sliding opening 4. The sliding opening 4 allows the operator to quickly replace the lower fixing strip 5 and the upper fixing strip 6, which have limiting grooves 15 of different sizes. The lower fixing strip 5 and the upper fixing strip 6 are vertically slidably inserted into the sliding mouth 4, and the fixed chamber 2 has an opening 7. It should be noted that the cutting component 4, which consists of a connecting shaft, a hydraulic pump, etc., is existing technology. For details, please refer to the construction steel bar cutting device disclosed in application number 202021765796.7. It can perform horizontal movement and cutting under the horizontal push of the cylinder. These are all existing mature technologies, so they will not be described in detail here.

[0024] Also includes:

[0025] Limiting component, the limiting component is used to limit and fix the upper fixing bar 6.

[0026] Multiple limiting grooves 15 are provided on the opposite side walls of the upper fixing strip 6 and the lower fixing strip 5. The limiting grooves 15 are used to place and limit the pipe.

[0027] The limiting assembly includes an L-shaped plate 8 vertically slidably connected within the opening 7. A screw 9 is rotatably connected to the top of the L-shaped plate 8, and the screw 9 is threadedly connected to the fixing chamber 2. A pull rod 11 is horizontally slidably connected to the L-shaped plate 8. By pulling the pull rod 11, the operator compresses the spring 13, and the baffle 12 moves away from the upper fixing strip 6, making it easy to remove the upper fixing strip 6, the pipe, and the lower fixing strip 5. The upper fixing strip 6 and the lower fixing strip 5 can be replaced with those that match the pipe diameter, thus ensuring a stable clamping and fixing effect. Baffles 12 are fixedly connected to the opposite ends of the two pull rods 11. Springs 13 are sleeved on the pull rods 11, and the two ends of the springs 13 are fixedly connected to the L-shaped plate 8 and the baffles 12, respectively.

[0028] The bottom surface of the baffle 12 contacts the top surface of the upper fixing strip 6. The baffle 12 stabilizes the upper fixing strip 6 and prevents it from wobbling up and down.

[0029] The L-shaped plate 8 has a limiting opening 14 to facilitate the horizontal sliding of the pull rod 11, and the limiting opening 14 is rectangular.

[0030] The end of the screw 9 furthest from the L-shaped plate 8 is fixedly connected to a screw block 10, which facilitates the operator's rotation of the screw 9. The screw block 10 is ergonomically designed, reflecting the overall user-friendly design of the device.

[0031] The functional principle of this utility model can be explained through the following operation methods:

[0032] Place the pipe into the fixed chamber 2, ensuring that the pipe is located within the limiting groove 15 on the lower fixed bar 5 and the upper fixed bar 6.

[0033] The operator rotates the screw 9 by turning the screw block 10, which in turn causes the L-shaped plate 8 to slide vertically within the opening 7. Due to the elastic force of the spring 13, the pull rod 11 slides horizontally, so that the baffle 12 is located directly above the upper fixing bar 6, and the bottom surface of the baffle 12 is in contact with the top surface of the upper fixing bar 6.

[0034] As the screw 9 rotates, the upper fixing bar 6 moves vertically downwards and then tightly presses and fixes the pipe to be cut.

[0035] After the pipe is fixed, the cutting assembly 3 is activated to cut it.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
