TECHNICAL FIELD
[0001] The application relates to the technical field of pipeline fixing devices, in particular to a pipeline fixing device for a water pump interface. BACKGROUND
[0002] The water pump is one of the indispensable important equipment in modern industry and agriculture, and is widely used in water supply, drainage, irrigation and other fields. In particular, in the construction of farmland water conservancy, the role of the water pump is particularly significant, which can effectively improve the utilization rate of water resources and promote the improvement of agricultural production efficiency. In actual use, the water pump usually needs to be used in cooperation with the pipeline, and the inlet and outlet of the water pump are detachably connected with the pipeline. Therefore, each time the water pump is used, the pipeline needs to be fixedly connected with the water pump interface, and in this process, the stability and reliability of the connection between the pipeline and the water pump need to be ensured to prevent the pipeline from falling off, and the sealing of the connection between the pipeline and the water pump needs to be ensured to reduce the water loss.
[0003] The connection between the pipeline and the water pump directly affects the working reliability and stability of the whole system. At present, in order to ensure the stable connection between the water outlet of the water pump and the pipeline, the industry generally adopts the steel wire rope binding fixing method. Although it can meet the basic needs to a certain extent, it has exposed many shortcomings in actual application. First, the operation is tedious and time-consuming, and every time it needs to be twisted by using pliers and other tools, which is not convenient to use and requires a large amount of labor. Second, it is difficult to ensure the safety and reliability of long-term use, and the falling off or water leakage phenomenon often occurs due to poor binding, which seriously affects the work efficiency and equipment operation quality. Third, the steel wire rope is easy to bend and deform after binding, and will be broken after a few uses, which is difficult to be repeatedly used and is serious waste. CONTENT OF THE INVENTION
[0004] In order to improve the convenience and stability of the pipeline fixing at the water pump interface, the application provides a pipeline fixing device for a water pump interface.
[0005] The pipeline fixing device for the water pump interface provided by the application adopts the following technical scheme:
[0006] A pipeline fixing device for a water pump interface, comprising a mounting seat, a rotating handle and a fixed pull rope.
[0007] The mounting seat comprises an arc-shaped abutting rod for abutting against the outer circumferential surface of the pipeline and a threaded rod fixed on the arc-shaped abutting rod; the threaded rod is vertically installed on the outer side of the middle part of the arc-shaped abutting rod.
[0008] The rotating handle comprises an operating rod and a rotating rod, one end of the rotating rod is fixedly connected to one side of the middle part of the operating rod, and the other end of the rotating rod is threadedly connected with the threaded rod; the rotating rod is provided with a connecting piece capable of rotating circumferentially relative to the rotating rod.
[0009] Both ends of the fixed pull rope are provided with pull rings, and the pull rings at both ends of the fixed pull rope are detachably sleeved on both sides of the connecting piece.
[0010] In use, the end of the pipeline is sleeved on the interface connecting end of the water pump. Then, the fixed pull rope is wound around one end of the pipeline, leaving two pull rings at the end of the fixed pull rope, and the arc abutting rod is abutted against the outside of the end of the pipeline. Then, the pull rings at both ends of the fixed pull rope are connected to both sides of the connecting piece. The rotating rod is driven to rotate by rotating the operating rod. Since the rotating rod is threadedly connected with the threaded rod and the threaded rod is fixed, the rotating rod drives the entire rotating handle to move upwards, thereby driving the pull rings at both ends of the fixed pull rope to move away from the pipeline, and further tightening and locking the entire fixed pull rope and clamping the end of the pipeline.
[0011] By adopting the above technical scheme, the pipeline fixed to the water pump interface is realized. In the present application, the mounting seat is tightly attached to the outer circumferential surface of the pipeline through the arc abutting rod, and has a large contact area. The tightening of the fixed pull rope clamps the pipeline and enables the entire device to be firmly positioned on the pipeline. The design of the rotating handle facilitates manual operation, and the threaded connection between the rotating rod and the threaded rod can flexibly adjust the fixing force. The structural design in the present application not only improves the convenience of pipeline fixing, but also enhances the reliability of the fixing effect, and reduces the damage to the surface of the pipeline.
[0012] Optionally, the threaded rod is a threaded sleeve, the threaded rod has an internal thread, and the rotating rod has an external thread. The end of the rotating rod away from the operating rod is inserted into the threaded rod and threadedly connected with the threaded rod.
[0013] By adopting the above technical scheme, the operator only needs to rotate the operating rod to conveniently and quickly adjust the tightness of the fixed pull rope, without the need for additional tools, thereby greatly improving the operation convenience. At the same time, this threaded connection can provide more stable mechanical connection performance, ensuring the firmness and reliability during pipeline fixing, and effectively avoiding the problem that the traditional steel wire rope binding method is easy to loosen. The entire device is stable and reliable, and the stress is stable and not easy to damage.
[0014] Optionally, the external thread on the rotating rod is divided into two parts, the external thread near the operating rod of the rotating rod is a positive thread, and the external thread near the threaded rod of the rotating rod is a reverse thread; the connecting piece is arranged at the position near the operating rod of the rotating rod and is threadedly connected with the positive thread.
[0015] By adopting the above technical scheme, when the rotating rod rotates, the threaded rod is fixed, and the connecting piece will not rotate under the pulling and limiting action of the fixed pull rope, so that the rotating rod rotating can drive the entire rotating handle to lift and simultaneously drive the connecting piece to lift synchronously, thereby greatly improving the efficiency of tightening or loosening the fixed pull rope and making the use more convenient and efficient.
[0016] Optionally, as another scheme, an annular groove is formed in the rotating rod, the connecting piece is sleeved on the rotating rod and embedded in the annular groove, and the connecting piece is axially limited and circumferentially rotatably connected with the rotating rod.
[0017] By adopting the above technical scheme, the rotating rod rotating can drive the entire rotating handle to lift and further drive the connecting piece to lift synchronously, thereby driving the pull rings at both ends of the fixed pull rope to move away from the pipeline direction, and further tightening and locking the entire fixed pull rope and clamping the end of the pipeline. The entire device is simple and labor-saving, stable and reliable.
[0018] Optionally, the connecting piece has a hanging ear on each side, and an end of the hanging ear away from the rotating rod extends obliquely toward one side of the operating rod; or the connecting piece is a butterfly nut.
[0019] By adopting the above technical scheme, the pull ring of the fixed pull rope can be more conveniently installed and disassembled. The obliquely extending structure of the hanging ear increases the stability of contact with the pull ring, avoids accidental falling, and facilitates the installation action of the operator with one hand. The butterfly nut can be directly used by purchasing existing mature products, without separate processing, thereby saving costs.
[0020] Optionally, the arc-shaped abutting rod is in the shape of an arc-shaped long strip plate, two arc-shaped abutting rods are arranged side by side and spaced apart, the two arc-shaped abutting rods are fixedly connected through a connecting rib, and the end of the threaded rod is fixedly connected to the connecting rib between the two arc-shaped abutting rods.
[0021] By adopting the above technical scheme, the arc-shaped abutting rod can better fit the outer circumferential surface of the pipeline, increase the contact area, and thereby improve the fixing stability. Meanwhile, the two arc-shaped abutting rods are fixedly connected together through the connecting rib, thereby further enhancing the rigidity and strength of the overall structure, avoiding deformation or damage of a single arc-shaped abutting rod due to uneven stress. In addition, the end of the threaded rod is fixedly connected to the connecting rib, thereby achieving uniform distribution of force, improving the adaptability of the device to different diameter pipelines, and ensuring the reliability and durability in the fixing process.
[0022] Optionally, the fixed pull rope comprises a steel strand and a protective layer outside the steel strand, the protective layer being a rust-proof coating or a sleeve made of nylon material.
[0023] By adopting the above technical scheme, the fixed pull rope is composed of a steel strand and a protective layer, the protective layer can effectively prevent the steel strand from rusting and corroding, and prolong the service life of the fixed pull rope. At the same time, the protective layer adopts a rust-proof coating or a sleeve made of nylon material, which not only improves the weather resistance of the fixed pull rope, but also reduces the friction damage to the outer surface of the pipeline, ensuring the stability and reliability of the fixing effect. The fixed pull rope has a long service life and can be repeatedly used, thereby greatly reducing the use cost of the entire device.
[0024] Optionally, each end of the fixed pull rope is provided with a clamping block, and the two ends of the fixed pull rope are clamped in the clamping blocks to form the pull ring through rotation.
[0025] By adopting the above technical scheme, the two ends of the fixed pull rope form a pull ring through the clamping blocks, which makes the installation of the fixed pull rope more stable and reliable. The design of the pull ring facilitates quick assembly with the connecting piece, improves the convenience of operation, and is simple to manufacture and low in cost.
[0026] Optionally, the clamping block comprises a first clamping plate and a second clamping plate that are attached to each other, and the two ends of the first clamping plate and the second clamping plate are detachably fixed by lock bolts. A first arc-shaped groove is formed on the side of the first clamping plate facing the second clamping plate, and a second arc-shaped groove corresponding to the first arc-shaped groove is formed on the side of the second clamping plate facing the first clamping plate. Rubber pads are arranged on the inner walls of the first arc-shaped groove and the second arc-shaped groove. When the first clamping plate and the second clamping plate are attached to each other, the first arc-shaped groove and the second arc-shaped groove form a clamping hole for clamping the fixed pull rope.
[0027] By adopting the above technical scheme, the clamping block is composed of a first clamping plate and a second clamping plate, which can be fixedly connected by lock bolts, facilitating disassembly and adjustment. The first clamping plate and the second clamping plate are respectively provided with arc-shaped grooves corresponding to each other, which can closely fit the shape of the fixed pull rope, increase the contact area, and thus improve the clamping stability. At the same time, the arc-shaped grooves are provided with rubber pads, which can not only enhance the friction and prevent the fixed pull rope from sliding, but also protect the surface of the fixed pull rope from damage. The finally formed clamping hole can firmly clamp the fixed pull rope, prevent it from loosening, and ensure its reliability during use, thereby achieving effective fixation of the pipeline.
[0028] Optionally, the mounting seat and the rotating handle are made of stainless steel, and the outer circumferential surfaces of the mounting seat and the rotating handle are provided with a zinc plating layer.
[0029] By adopting the technical scheme, the mounting seat and the rotating handle are made of stainless steel material, so that the corrosion resistance and mechanical strength of the components can be effectively improved, and the service life is prolonged. Meanwhile, the galvanized layer arranged on the mounting seat and the rotating handle further enhances the corrosion resistance, ensures that the device is not prone to rust in a humid environment for a long time, and improves the reliability and durability of the overall device.

[0044] The technical solutions in the embodiments of the present application will be described below with reference to the drawings Figure 1 - the drawings Figure 4 In order to make the technical solutions in the embodiments of the present application clear and complete, the described embodiments are only possible technical implementations of the present application, and not all possible implementations. Those skilled in the art can obtain other embodiments by combining the embodiments of the present application without creative labor, and these embodiments are also within the protection scope of the present application.
[0045] Embodiment 1
[0046] With reference to Figure 1 and Figure 2 It is shown that the pipe fixing device for water pump interface provided by the embodiments of the present application comprises a mounting seat 10, a rotating handle 20 and a fixed pull rope 30. The mounting seat 10 comprises an arc-shaped abutting rod 11 for abutting against the outer circumferential surface of the pipe and a threaded rod 12 fixedly connected to the arc-shaped abutting rod 11. The threaded rod 12 is vertically installed on the outer side of the middle part of the arc-shaped abutting rod 11. The rotating handle 20 comprises an operating rod 21 and a rotating rod 22. One end of the rotating rod 22 is fixedly connected to one side of the middle part of the operating rod 21, and the other end of the rotating rod 22 is threadedly connected with the threaded rod 12. A connecting piece 23 capable of rotating circumferentially relative to the rotating rod 22 is arranged on the rotating rod 22. The fixed pull rope 30 has a pull ring 31 at each end. The pull rings 31 at the two ends of the fixed pull rope 30 are detachably sleeved on the two sides of the connecting piece 23. In the present application, the two sides of the connecting piece 23 have a hanging ear 231 for hanging the pull ring 31. The end of the hanging ear 231 away from the rotating rod 22 extends obliquely towards one side of the operating rod 21. In this way, the pull ring 31 of the fixed pull rope 30 can be more conveniently installed and detached, and the installation operation can be completed by one hand of an operator. Alternatively, the connecting piece 23 is a butterfly nut. The wings on the two sides of the butterfly nut are used to hang the pull ring 31 of the fixed pull rope 30. The butterfly nut can be directly used by purchasing existing mature products, without the need for separate processing, thereby saving costs.
[0047] Further, with reference to Figure 1 and Figure 2As shown, the threaded rod 12 is a threaded sleeve in this embodiment, the threaded rod 12 has an internal thread, the rotating rod 22 has an external thread 221, the end of the rotating rod 22 away from the operating rod 21 is inserted into the threaded rod 12 and the two are threadedly connected. The external thread 221 on the rotating rod 22 is divided into two parts, the external thread 221 on the rotating rod 22 close to the operating rod 21 is a positive thread, and the external thread 221 on the rotating rod 22 close to the threaded rod 12 is a reverse thread; the connecting piece 23 is arranged at the position of the rotating rod 22 close to the operating rod 21 and is threadedly connected with the positive thread. When the rotating rod 22 rotates, since the threaded rod 12 is fixed and the connecting piece 23 cannot rotate under the pulling and limiting action of the fixed pull rope 30, the rotating rod 22 rotates to drive the connecting piece 23 to rise and fall synchronously, thereby greatly improving the efficiency of the fixed pull rope 30 when it is tightened or loosened, and the use is more convenient and efficient.
[0048] With reference to Figure 2 As shown, the arc-shaped abutting rod 11 is in the shape of an arc-shaped long strip plate, two arc-shaped abutting rods 11 are arranged side by side and are spaced apart, the two arc-shaped abutting rods 11 are fixedly connected through the connecting rib 13, and the end of the threaded rod 12 is fixedly connected to the connecting rib 13 between the two arc-shaped abutting rods 11. In this way, the arc-shaped abutting rod 11 can better fit the outer circumferential surface of the pipeline, increase the contact area, and thus improve the fixing stability.
[0049] The fixed pull rope 30 in this application includes a steel strand and a protective layer outside the steel strand, the protective layer is a rust-proof coating or a sleeve made of nylon material. The protective layer can effectively prevent the steel strand from rusting and corroding, and prolong the service life of the fixed pull rope 30. At the same time, the protective layer is a rust-proof coating or a sleeve made of nylon material, which not only improves the weather resistance of the fixed pull rope 30, but also reduces the friction damage to the outer surface of the pipeline, ensuring the stability and reliability of the fixing effect. The fixed pull rope 30 has a long service life and can be repeatedly used, thereby greatly reducing the use cost of the entire device.
[0050] With reference to Figure 1 and Figure 3As shown, the two ends of the fixed pull rope 30 are each provided with a clamping block 40, and the two ends of the fixed pull rope 30 are clamped in the clamping block 40 to form a pull ring 31 through rotation. The clamping block 40 comprises a first clamping plate 41 and a second clamping plate 42 which are attached to each other, and the two ends of the first clamping plate 41 and the second clamping plate 42 are detachably fixed by locking bolts 43; a first arc-shaped recess 411 is formed on the side of the first clamping plate 41 facing the second clamping plate 42, and a second arc-shaped recess 421 corresponding to the first arc-shaped recess 411 is formed on the side of the second clamping plate 42 facing the first clamping plate 41; rubber pads 44 are arranged on the inner walls of the first arc-shaped recess 411 and the second arc-shaped recess 421; when the first clamping plate 41 and the second clamping plate 42 are attached to each other, the first arc-shaped recess 411 and the second arc-shaped recess 421 form a clamping hole 45 for clamping the fixed pull rope 30. The first clamping plate 41 and the second clamping plate 42 are tightly attached to the shape of the fixed pull rope 30 through the arc-shaped recesses, increasing the contact area and thus improving the clamping stability. At the same time, the rubber pads 44 arranged in the first arc-shaped recess 411 and the second arc-shaped recess 421 not only enhance the friction and prevent the fixed pull rope 30 from sliding, but also protect the surface of the fixed pull rope 30 from being damaged. The finally formed clamping hole 45 can firmly clamp the fixed pull rope 30, prevent loosening, ensure the reliability during use, and thus achieve effective fixation of the pipeline.
[0051] In the present application, the mounting seat 10 and the rotating handle 20 are made of stainless steel, and the outer periphery of the mounting seat 10 and the rotating handle 20 is provided with a zinc plating layer, which can effectively improve the corrosion resistance and mechanical strength of the components and prolong the service life.
[0052] The implementation principle of the present embodiment is as follows: in use, the end of the pipeline is sleeved on the interface connecting end of the water pump. Then the fixed pull rope 30 is wound around one end of the end of the pipeline, leaving two pull rings 31 at the end of the fixed pull rope 30, and the arc-shaped abutting rod 11 is abutted on the outside of the end of the pipeline. Then the pull rings 31 at the two ends of the fixed pull rope 30 are connected to the two sides of the connecting piece 23; the rotating rod 22 is driven to rotate by rotating the operating rod 21, and since the rotating rod 22 is threadedly connected with the threaded rod 12 and the threaded rod 12 is fixed, the rotating rod 22 will drive the entire rotating handle 20 to move upwards, thereby driving the pull rings 31 at the two ends of the fixed pull rope 30 to move away from the pipeline, and finally the entire fixed pull rope 30 is tightened and locked, and the end of the pipeline is clamped tightly.
[0053] The mounting seat 10 in the application is closely attached to the outer circumferential surface of the pipeline through the arc-shaped abutting lever 11, has a large contact area, and fixes the tensioning of the pull rope 30, which on one hand clamps the pipeline and on the other hand enables the entire device to be firmly positioned on the pipeline; the design of the rotating handle 20 facilitates manual operation, and the threaded connection between the rotating lever 22 and the threaded rod 12 can flexibly adjust the fixing force; the structural design in the application not only improves the convenience of pipeline fixation, but also enhances the reliability of the fixing effect, and at the same time reduces the damage that may be caused to the surface of the pipeline.
[0054] Embodiment 2
[0055] This embodiment is substantially the same as embodiment 1, except that in this embodiment, an annular groove 222 is formed on the rotating lever 22, the connecting piece 23 is sleeved on the rotating lever 22 and embedded in the annular groove 222, and the connecting piece 23 is axially limited and circumferentially rotatably connected with the rotating lever 22.
[0056] The rotating of the rotating lever 22 will drive the entire rotating handle 20 to ascend and descend, and in turn drive the connecting piece 23 to synchronously ascend and descend, so as to drive the pull rings 31 at both ends of the fixed pull rope 30 to move away from the pipeline, and in turn tighten and lock the entire fixed pull rope 30 and clamp the end of the pipeline. The entire device is simple and labor-saving to operate, stable and reliable.
