Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and more specifically, to a waterproof hose clamp and its hose connector. Background Technology

[0002] Agricultural PVC hoses are lightweight, durable, and corrosion-resistant, making them an excellent aid for farmland irrigation. They can be flexibly laid in fields and along edges of crops to efficiently deliver water and fertilizer to the roots, improving irrigation efficiency and promoting water-saving agriculture. Their smooth inner walls reduce water flow resistance, and their anti-aging materials extend their service life. They bring convenience and benefits to agricultural production, offering precise water control, reduced waste, promotion of crop growth, even coverage, adaptability to different terrains, improved irrigation efficiency, and anti-aging properties.

[0003] In existing technologies, the connection between agricultural PVC hoses and threaded pipes typically involves connecting the hose to a connector and then wrapping it with tie wire. However, excessive force during the tying process can damage the agricultural PVC hose and cause leaks. Existing technology discloses an adaptable hose clamp, which includes a base, a rotating frame, a slot, a threaded rod, a pressure plate, and a connecting hook. The rotating frame is hinged to the base, and both the rotating frame and the base have arc-shaped slots. A threaded rod passes through and is threadedly connected to the rotating frame, with its end rotatably connected to the top of the pressure plate. The pressure plate is located within the slot. A connecting hook for connecting to the base is fixed to one end of the rotating frame, and a positioning groove is formed on the plane of the connecting hook. An arc-shaped locking block that mates with the positioning groove is fixed to the base. This solution uses a relatively rotatable base and rotating frame to clamp the hose, and the threaded rod drives the pressure plate to press down, thereby clamping hoses of different sizes. The connecting hook connects and fixes the base and rotating frame, thus improving the stability when clamping hoses of different diameters.

[0004] However, when the clip engages the hose, the inner wall of the clip cannot completely fit against the outer wall of the hose, resulting in uneven pressure on the hose. Areas with less pressure on the hose deform less, creating gaps between the hose and the connector, leading to insufficient overall sealing and potential water leakage. Utility Model Content

[0005] The purpose of this invention is to overcome the problem of insufficient sealing when clamping hoses in the prior art, and to provide a water-proof hose clamp that can improve the sealing of the connection between the hose and the connector, and avoid or reduce water leakage.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A waterproof hose clamp is provided, comprising a first outer buckle, a second outer buckle rotatably connected to the first outer buckle, a first waterproof buckle, a second waterproof buckle, and a plurality of first elastic elements. One end of the first outer buckle is connected to one end of the second outer buckle by a locking member. The inner wall of the first outer buckle is connected to the outer wall of the first waterproof buckle by the first elastic elements. The inner wall of the second outer buckle is connected to the outer wall of the second waterproof buckle by the first elastic elements. When the first outer buckle and the second outer buckle form a ring, the first elastic elements are evenly distributed circumferentially along the first outer buckle. The elastic force of the first elastic elements is radially distributed.

[0008] This utility model discloses a water-proof hose clamp. When connecting a hose and a connector, one end of the hose is first inserted into the connector. Then, the hose clamp is removed and placed over the connection between the hose and the connector. The locking mechanism is then adjusted to lock the first and second outer buckles. During the tightening process, the first and second outer buckles compress the first elastic element, which in turn compresses the first and second waterproof buckles, causing them to adhere to the outer wall of the hose. A soft contact seal is formed between the first and second waterproof buckles and the hose. The clamping force of the first and second outer buckles can be evenly transmitted to the first and second waterproof buckles through multiple first elastic elements. The first elastic elements act as a buffer, making the hose more evenly compressed and preventing gaps between the hose and the connector due to insufficient deformation in some areas. This improves the overall sealing performance of the connector and avoids or reduces water leakage.

[0009] Furthermore, both the first waterproof buckle and the outer wall of the second waterproof buckle are provided with a plurality of sliding members. The first outer buckle and the second outer buckle are slidably connected to the sliding members, and the first elastic member is fitted over the outside of the sliding members. The slidable connection between the first outer buckle and the second outer buckle and the sliding members improves the stability of the hose clamp, and the first elastic member, fitted over the sliding members, provides support for the first elastic member and reduces the deviation of the elastic force direction of the first elastic member.

[0010] Furthermore, the sliding component includes a fixing block, a sliding rod, and a limiting block. Sliding blocks are fixed to the side walls of both the first and second outer buckles. The fixing block is fixed to the outer walls of the first and second waterproof buckles. One end of the sliding rod is connected to the fixing block, and the other end is connected to the limiting block. The sliding rod and the sliding block are slidably connected. The limiting block restricts the sliding of the sliding block. Both ends of the first elastic element are connected to the fixing block and the sliding block, respectively. The first elastic element is fitted onto the outside of the sliding rod. The sliding block and the sliding rod are slidably connected, and the fixing block and the limiting block restrict the sliding stroke of the sliding block, resulting in better stability.

[0011] Furthermore, one end of the first outer buckle is provided with a first buckle plate, and one end of the second outer buckle is provided with a second buckle plate. The second buckle plate has a locking groove. The locking element includes a locking strip and a fastening nut. One end of the locking strip is rotatably connected to the first buckle plate, and the other end is threadedly connected to the fastening nut. When the hose clamp is in the locked state, the locking strip is located in the locking groove, and the fastening nut abuts against the side of the second buckle plate. After the first and second outer buckles are fastened, the locking strip is rotated into the locking groove, and then the fastening nut is tightened so that the fastening nut abuts against the side of the second buckle plate, thereby applying a clamping force to the hose, causing the hose to deform and press against the connector. This fixing method is simple, convenient, and has a good fixing effect.

[0012] A hose connector is provided, comprising a hose clamp, a connector body, and a connecting tube. The connector body has an internal flow channel, and the connecting tube is connected to both ends of the flow channel. The connecting tube is inserted into a hose. A groove is formed on the outer wall of the connecting tube, and the hose clamp is used to clamp the hose within the groove. The groove design allows the hose greater deformation space under the action of the hose clamp, resulting in a tighter clamping between the hose and the connector, and also improving the sealing performance.

[0013] Furthermore, it also includes two limiting mechanisms, each including a limiting member and a second elastic member. Connecting grooves for installing the limiting mechanisms are provided on both sides of the connector body. One end of the second elastic member is fixed to the inner wall of the connecting groove, and the other end is connected to the limiting member. The limiting member is provided with an insert block. One end of the connecting tube is provided with a connecting plate, and one side of the connecting plate is provided with a slot. The connecting plate and the connecting groove are slidably connected in the vertical direction. The elastic force of the second elastic member is along the axial direction of the connecting tube. When the connecting plate slides to the inner bottom surface of the connecting groove, the insert block is inserted into the slot along the axial direction of the connecting tube. When connecting the connecting pipe and the connector body, the connecting plate of the connecting pipe is slid into the connecting groove. When the insert is not inserted into the slot, the second elastic element is compressed. When the connecting plate slides to the inner bottom surface of the connecting groove, the connecting plate moves along the axial direction of the connecting pipe under the elastic force of the second elastic element. The insert is inserted into the slot of the connecting pipe along the axial direction. The limiting element presses the connecting plate against the inner wall of the connecting groove. The connector is designed to be detachable, and the connecting pipe can be replaced, which is convenient for installing hoses of different diameters. Only the connecting pipe needs to be replaced, without replacing the entire connector. The assembly of the connecting pipe is simple and convenient, and the convenience is higher.

[0014] Furthermore, the limiting mechanism also includes a sliding sleeve and a fastening post. The sliding sleeve is fixed to the top of the limiting member, and a sliding groove is formed inside the sliding sleeve. The fastening post is threadedly connected to the top surface of the connector body. The sliding groove and the fastening post are slidably connected, and the sliding direction is along the axial direction of the connecting pipe. The sliding sleeve improves the stability of the limiting member's axial movement in the connecting pipe. When the insert is inserted into the slot of the connecting pipe, the operator tightens the fastening post to lock the sliding sleeve, thereby locking the movement of the limiting member and preventing the insert from dislodging from the slot, resulting in better stability.

[0015] Furthermore, a first inlay groove is provided on both sides of the connector body, and a first sealing strip is disposed in the first inlay groove. A second inlay groove is provided on one side of the connecting plate, and a second sealing strip is disposed in the second inlay groove. The outer side of the first sealing strip and the outer side of the second sealing strip are in contact with each other. The contact between the first sealing strip and the second sealing strip can improve the sealing performance of the connector and reduce leakage.

[0016] Furthermore, the connector body includes a frame, a filter cover, and a filter assembly. The filter cover is slidably connected to the frame in a vertical direction. The inlet end of the filter cover has multiple filter holes, and the filter assembly is installed at the outlet end of the filter cover. The filter holes of the filter cover can filter larger impurities, preventing clogging of the filter assembly. The filter assembly can perform fine filtration of the water flow, improving water quality. By combining the filtration function with the connector, there is no need to install a filter device at the end of the pipe, saving space.

[0017] Furthermore, the connector body also includes a water baffle. A sliding strip is fixed to the inner wall of the water outlet end of the water baffle, and a support strip is fixed to the bottom of the sliding strip. The outer wall of the water baffle is recessed inward to form a first recess, and the inner wall of the water baffle is protruded inward to form a first protrusion. The first recess is slidably connected to the sliding strip in the vertical direction. The bottom of the water baffle abuts against the top of the support strip. The filter assembly includes fasteners, a handle arranged from top to bottom, and several filter plates. A second recess is opened on the side of the filter plate. The second recess is slidably connected to the first protrusion in the vertical direction. The bottom surface of the lowest filter plate abuts against the inner bottom surface of the water baffle. The handle is connected to all the filter plates by fasteners. The water baffle provides support for the filter assembly while ensuring that water can flow through it. The filter plate is slidably connected to the first protrusion for easy installation and removal, and facilitates cleaning or replacement of the filter plate. The handle and all filter plates can be installed or removed as a whole. The handle is easy to remove, and disassembly can be achieved by loosening the fasteners, making operation convenient.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The first elastic element can act as a buffer, making the first and second waterproof buckles fit more tightly against the outer wall of the hose, and the hose is pressed more evenly. This prevents the hose from deforming too little in some places, which could cause gaps between the hose and the connector, thus improving the overall sealing of the connector and preventing or reducing water leakage.

[0020] 2. The setting of the limiting mechanism makes the assembly between the connecting pipe and the connector body simpler and more convenient. The connector is designed to be detachable, and the connecting pipe can be replaced, which is convenient for installing hoses of different diameters. Only the connecting pipe needs to be replaced, without replacing the entire connector.

[0021] 3. The filter assembly can perform fine filtration of water flow, improving water quality. By combining the filtration function with the connector, there is no need to install a filter device at the end of the pipe, saving space. Attached Figure Description

[0034] A waterproof hose clamp, such as Figure 1 and Figure 2As shown, it includes a first outer buckle 110, a second outer buckle 120 rotatably connected to the first outer buckle 110, a first waterproof buckle 140, a second waterproof buckle 150, and sixteen first elastic members 160. In this embodiment, the first waterproof buckle 140 and the second waterproof buckle 150 are made of rubber. Each sliding member 170 includes a fixing block 171, a sliding rod 172, and a limiting block 173. Four sliding blocks 180 are respectively provided on both sides of the first waterproof buckle 140 in the axial direction, and four sliding blocks 180 are evenly provided on both sides of the second waterproof buckle 150 in the axial direction. When the first outer buckle 110 is rotatably connected to the second outer buckle 120, a first waterproof buckle 140, a second waterproof buckle 150, and sixteen first elastic members 160, the first outer buckle 140 is rotatably connected to the second outer buckle 120, a first waterproof buckle 140, a second waterproof buckle 150, and sixteen first elastic members 160. When buckle 110 and outer buckle 120 form a ring, eight sliding blocks 180 located on the same side of the axial direction are evenly distributed along the circumference of the first outer buckle 110. Fixing block 171 is fixed to the outer wall of the first waterproof buckle 140 and the second waterproof buckle 150. One end of sliding rod 172 is connected to fixing block 171, and the other end is connected to limiting block 173. Sliding rod 172 is slidably connected to sliding block 180. Limiting block 173 is used to restrict the sliding of sliding block 180. Both ends of the first elastic element 160 are connected to fixing block 171 and sliding block 180 respectively. The 60 is fitted onto the outside of the slide bar 172. When the first waterproof buckle 140 and the second waterproof buckle 150 are combined to form a ring, in this embodiment, the first elastic element 160 is a straight spring. The inner wall of the first outer buckle 110 is connected to the outer wall of the first waterproof buckle 140 through the first elastic element 160, and the inner wall of the second outer buckle 120 is connected to the outer wall of the second waterproof buckle 150 through the first elastic element 160. The elastic force of the first elastic element 160 is along the radial direction of the first outer buckle 110. In this embodiment, one end of the first outer buckle 110 is provided with a first buckle plate 111, and the second outer buckle... One end of the 120 is provided with a second buckle plate 121, which has two locking grooves 122. The locking member 130 includes two locking strips 131 and two fastening nuts 132. One end of the locking strip 131 is rotatably connected to the first buckle plate 111, and the other end is threadedly connected to the fastening nut 132. When the hose clamp 100 is in the locked state, the two locking strips 131 are respectively located in the locking grooves 122. The fastening nut 132 is used to press against the side of the second buckle plate 121. In addition, the locking member 130 can also be connected by snap-fit ​​connection, pin connection, or other connection methods.

[0035] The working principle of this embodiment is as follows:

[0036] This utility model discloses a water-proof hose clamp. When connecting a hose and a connector, first insert one end of the hose into the connector, then remove the hose clamp 100 and place it on the connection between the hose and the connector. Rotate the first outer buckle 110 and the second outer buckle 120, then rotate the clamping strip 131 into the clamping groove 122, and then tighten the fastening nut 132 so that the fastening nut 132 abuts against the side of the second buckle plate 121. During the tightening process of the fastening nut 132, the first outer buckle 110 and the second outer buckle 120 will slide along the sliding member 170, thereby squeezing the first elastic member 160. The first elastic member 160 will also squeeze the first waterproof buckle 140 and the second waterproof buckle 150, so that the first waterproof buckle 140 and the second waterproof buckle 150 are attached to the outer wall of the hose. After locking, a soft contact seal is formed between the first waterproof buckle 140, the second waterproof buckle 150 and the hose, so that the hose deforms and presses tightly onto the connector.

[0037] The beneficial effects of this embodiment are as follows:

[0038] The first outer buckle 110 and the first waterproof buckle 140 are connected by multiple first elastic elements 160, and the second outer buckle 120 and the second waterproof buckle 150 are connected by multiple first elastic elements 160. The clamping force of the first outer buckle 110 and the second outer buckle 120 can be evenly transmitted to the first waterproof buckle 140 and the second waterproof buckle 150 through multiple first elastic elements 160. The first elastic element 160 plays a buffering role, making the hose more evenly compressed, avoiding gaps between the hose and the connector due to insufficient deformation in some parts of the hose, improving the overall sealing of the connector, and avoiding or reducing water leakage. The sliding element 170 provides support for the first elastic element 160 and reduces the deviation of the elastic force direction of the first elastic element 160. The locking element 130 uses a locking strip 131 in conjunction with a locking groove 122 and a fastening nut 132, which is simple, convenient, and has a good fixing effect.

[0039] Example 2

[0040] This embodiment is a first embodiment of a hose connector, such as... Figure 3 As shown, the device includes a waterproof hose clamp 100, a connector body 200, two connecting pipes 300, and two limiting mechanisms 400, as described in Embodiment 1. The connector body 200 has an internal flow channel, with a connecting pipe 300 connected to each end of the flow channel. The connecting pipes 300 are used to insert into the hose, as described in Embodiment 1. Figure 4 As shown, a groove 310 is provided on the outer wall of the connecting pipe 300, and the hose clamp 100 is used to tighten the hose clamp 100 in the groove 310, such as... Figure 5 and Figure 6As shown, the limiting mechanism 400 includes a limiting member 410, twelve second elastic members 420, two sliding sleeves 430, and two fastening posts 440. In this embodiment, the second elastic members 420 are straight springs. Connecting grooves 211 for installing the limiting mechanism 400 are provided on both sides of the connector body 200. Spring grooves 213 are provided on both the left and right sides of each connecting groove 211. Six spring holes are evenly arranged vertically in each spring groove 213. One end of each second elastic member 420 is fixed to a spring hole. Inside, the other end is connected to the limiting member 410. The limiting member 410 is U-shaped, and an insert block 411 is provided at the bottom of the side of the limiting member 410. The top of the insert block 411 is beveled. The top of the limiting member 410 is also beveled. A sliding sleeve 430 is fixed to the top of the limiting member 410. A sliding groove 431 is provided inside the sliding sleeve 430. The fastening post 440 is threaded to the top surface of the connector body 200. The sliding groove 431 and the fastening post 440 are slidably connected, and the sliding direction is along the axial direction of the connecting pipe 300. Figure 4 As shown, a connecting plate 320 is provided at one end of the connecting pipe 300, and a slot 321 is provided on one side of the connecting plate 320. The connecting plate 320 and the connecting groove 211 are slidably connected in the vertical direction. The elastic force of the second elastic element 420 is along the axial direction of the connecting pipe 300. When the connecting plate 320 slides to the inner bottom surface of the connecting groove 211, the insert block 411 is inserted into the slot 321 along the axial direction of the connecting pipe 300. Figure 4 As shown, both sides of the connector body 200 are provided with a first inlay groove 212, and a first sealing strip is provided in the first inlay groove 212, such as... Figure 5 As shown, a second inlay groove 322 is provided on one side of the connecting plate 320, and a second sealing strip is provided in the second inlay groove 322. The outer side of the first sealing strip is in contact with the outer side of the second sealing strip.

[0041] The working principle of this embodiment is as follows:

[0042] This utility model discloses a flexible hose connector. When connecting the connecting pipe 300 and the connector body 200, the connecting plate 320 of the connecting pipe 300 is slid into the connecting groove 211, the limiting member 410 is pushed, and the sliding sleeve 430 slides relative to the fastening post 440. When the insert 411 is not yet inserted into the slot 321, the second elastic member 420 is compressed. When the connecting plate 320 slides to the inner bottom surface of the connecting groove 211, the insert 411 is aligned with the slot 321. Under the elastic force of the second elastic member 420, the connecting plate 320 moves axially along the connecting pipe 300, and the limiting member... 410 Presses the connecting plate 320 against the inner wall of the connecting groove 211, and inserts the plug 411 into the slot 321 of the connecting pipe 300 along the axial direction of the connecting pipe 300, thereby completing the assembly of the connecting pipe 300 and the connector body 200. Subsequently, the stability between the connecting pipe 300 and the connector body 200 can be strengthened by tightening the fastening post 440. When disassembling the connecting pipe 300, it is only necessary to loosen the fastening post 440, slide the limiting member 410 to make the plug 411 disengage from the slot 321, and then slide the connecting plate 320 to make the connecting plate 320 leave the connecting groove 211, thereby completing the disassembly.

[0043] The beneficial effects of this embodiment are as follows:

[0044] The connector is designed to be detachable, and the connecting pipe 300 can be replaced, facilitating the installation of hoses with different diameters. Only the connecting pipe 300 needs to be replaced, without replacing the entire connector. The assembly of the connecting pipe 300 is simple and convenient, enhancing usability. The sliding sleeve 430 improves the stability of the limiting member 410 moving axially within the connecting pipe 300. The fastening post 440 improves stability after locking, preventing the insert 411 from disengaging from the slot 321. The tops of both the limiting member 410 and the insert 411 are beveled. When installing the connecting plate 320, there is no need to manually pry open the limiting member 410; simply slide the connecting plate 320 downwards. Due to the beveled design, the limiting member 410 will move under the pressure of the connecting plate 320, improving convenience. The beveled design of the insert 411 is similar. The first and second sealing strips fit together, improving the connector's sealing performance and reducing leakage.

[0045] The remaining working principles of this embodiment are the same as those of Embodiment 1.

[0046] Example 3

[0047] This embodiment is a second embodiment of a hose connector. This embodiment is similar to Embodiment 2, except that, as shown in the figure... Figure 6 As shown, the connector body 200 includes a frame 210, a water filter cover 220, a filter assembly 240, and a water baffle 230. The water filter cover 220 is slidably connected to the frame 210 in the vertical direction, as shown. Figure 7 and Figure 8As shown, the top surface of the water filter cover 220 is provided with a handle 223. The water inlet end of the water filter cover 220 has multiple filter holes 224. The filter assembly 240 is installed at the water outlet end of the water filter cover 220. Two sliding strips 221 are fixed to the two opposite inner sidewalls of the water outlet end of the water filter cover 220, respectively. The sliding strips 221 are arranged vertically. A support strip 222 connects the bottom of the two opposite sliding strips 221. The outer wall of the water baffle 230 is recessed inward to form four first recesses 231. Due to the inward recesses of the first recesses 231, the inner wall of the water baffle 230 protrudes inward to form four first protrusions 232. The first recesses 231 and the sliding strips 221 are slidably connected in the vertical direction. The bottom of the water baffle 230 abuts against the top of the support strip 222. The filter assembly 240 includes fasteners 246 and a series of components arranged from top to bottom. The device includes a handle 241, a first filter plate 242, a second filter plate 243, and a third filter plate 244. The sides of the first filter plate 242, second filter plate 243, and third filter plate 244 are each provided with four second recesses 245 corresponding to the first protrusion 232. The second recesses 245 are slidably connected to the first protrusion 232 in the vertical direction. The bottom of the third filter plate 244 abuts against the inner bottom surface of the water baffle 230. The handle 241 is connected to the first filter plate 242, second filter plate, and third filter plate 244 by fasteners 246. In this embodiment, the fasteners 246 are bolt and nut assemblies. In this embodiment, the first filter plate 242 and third filter plate 244 are mesh filters used to filter large particles in the water, and the second filter plate 243 is activated carbon filters used to filter fine impurities in the water.

[0048] The working principle of this embodiment is as follows:

[0049] The filter holes 224 of the water filter cover 220 can filter larger impurities, preventing clogging of the filter assembly 240. The handle 223 facilitates the lifting of the water filter cover 220 and the filter assembly 240, combining the filtration function with the connector. This eliminates the need for a filter device at the end of the pipe, saving space. The water baffle 230 provides support for the filter assembly 240 while ensuring that all water flows through it.
