Description

Technical Field

[0001] The utility model relates to the technical field of rubber composite hoses, and particularly relates to a quick connection device for rubber composite hoses. Background Art

[0002] A rubber composite hose is a hose with a complex structure, usually composed of an inner layer tube, a reinforcing layer and an outer layer tube. The inner layer is usually made of rubber or plastic materials, the reinforcing layer uses synthetic fiber threads or wire meshes and other materials to enhance its strength and pressure resistance, and the outer layer is used to protect the internal structure from damage by the external environment. When some existing quick connection devices for rubber composite hoses connect rubber hoses, due to the softness of the rubber hoses, it is difficult to fix the rubber hoses during connection. At the same time, due to the softness of the rubber hoses, their shapes are easy to change during connection, resulting in poor sealing and water leakage, etc., which reduces both the connection efficiency and the use efficiency of the rubber hoses and is not conducive to use.

[0003] Therefore, a quick connection device for rubber composite hoses is invented. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a quick connection device for rubber composite hoses to solve the above problems.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A quick connection device for rubber composite hoses includes two groups of outer retaining rings and an inner retaining ring. Adjacent sides of the two groups of outer retaining rings are fixedly connected with connecting bottom blocks. Circular holes are opened inside the two groups of connecting bottom blocks. Inner retaining rings are fixedly connected to the outer sides of the two groups of connecting bottom blocks. The inner diameter of the inner retaining ring is the same as the diameter of the circular hole.

[0007] A regulating ring is movably sleeved on the outer walls of adjacent ends of the two groups of outer retaining rings. A transmission mechanism is fixedly connected to the inner wall of the regulating ring. Six expansion mechanisms are meshed with the outer wall of the transmission mechanism. The expansion mechanisms are arranged on both sides of the transmission mechanism. The six expansion mechanisms are arranged in a circumferential array with the inner retaining ring as the center.

[0008] Further, the expansion mechanism includes two groups of connecting bottom blocks. Three chutes are opened inside each of the connecting bottom blocks. Special-shaped sliders are slidably connected inside the chutes. Inner clamping plates are fixedly connected to the tops of the special-shaped sliders.

[0009] Further, activity grooves are formed inside the inner clamping plates, and a connecting rod is fixedly connected inside the activity grooves. Two groups of articulated sliders are slidably sleeved on the outer wall of the connecting rod. One end of a transmission rod is articulated inside each of the two groups of articulated sliders, and the other end of the transmission rod is articulated with an articulated block. The outer wall of the inner protection ring is fixedly connected to the inner wall of the articulated block.

[0010] Further, a threaded rod is threadedly connected to the inner wall of the special-shaped slider, and one end of the threaded rod is movably sleeved inside the connecting bottom block.

[0011] Further, the transmission mechanism includes bevel gears. The other end of the threaded rod is fixedly connected to the inner wall of the bevel gear. The outer wall of the bevel gear meshes with a plurality of groups of toothed plates. A connecting ring is fixedly connected to the opposite sides of the toothed plates, and the top end of the connecting ring is fixedly connected to the inner wall of the adjusting ring.

[0012] Further, limiting rings are fixedly connected to the outer walls of the two outer protection rings, and the outer walls of the limiting rings are movably sleeved inside the adjusting ring.

[0013] The technical effects and advantages of the present utility model:

[0014] 1. The use of the quick clamping connection device can simplify the installation and disassembly process. Operators do not need additional tools or professional skills. They only need to simply insert and tighten the connection device to complete the connection. Compared with traditional connection methods, quick clamping connection can significantly reduce the time and cost required for installation and maintenance, facilitate frequent replacement or adjustment of the hose, and the quick clamping connection device can connect hoses of different sizes and types, providing greater flexibility in system design.

[0015] 2. Both ends of the rubber composite hose connection device can be connected to hoses of different thicknesses. Allowing the connection of hoses of different thicknesses makes the system more flexible in design and installation. Different diameter hoses can be used in the same system to adapt to different flow requirements or installation conditions. Using a connection device that can connect hoses of different thicknesses can reduce the types and inventory levels of spare parts that need to be maintained and managed.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 6 As shown, the quick connection device for a rubber composite hose provided by the present utility model includes two groups of outer protective rings 1 and inner protective rings 4. Connecting bottom blocks 8 are fixedly connected to the adjacent sides of the two groups of outer protective rings 1. Circular holes are provided inside the two groups of connecting bottom blocks 8. Inner protective rings 4 are fixedly connected to the outer sides of the two groups of connecting bottom blocks 8. The inner diameter of the inner protective ring 4 is the same as the diameter of the circular hole;

[0026] A group of adjusting rings 2 are movably sleeved on the outer walls of the adjacent ends of the two groups of outer protective rings 1. A transmission mechanism is fixedly connected to the inner wall of the adjusting ring 2. Six groups of expansion mechanisms are meshed with the outer wall of the transmission mechanism, and the expansion mechanisms are arranged on both sides of the transmission mechanism. The six groups of expansion mechanisms are arranged in a circumferential array with the inner protective ring 4 as the center.

[0027] Insert the hose into the gap between the outer protective ring 1 and the inside of the inner clamping plate 3. The top of the hose is attached to the outer wall of the connecting bottom block 8. Then rotate the adjusting ring 2, so that the transmission mechanism inside the adjusting ring 2 drives the expansion mechanism to rotate, thereby driving the inner clamping plate 3 to move towards the inner wall direction of the outer protective ring 1, thereby pushing the inner and outer walls of the hose to be completely attached to the inner clamping plate 3. The outer wall of the hose is attached to the inner wall of the inner clamping plate 3, thereby fixing the hose.

[0028] The expansion mechanism includes two groups of connecting bottom blocks 8. Three sliding grooves are provided inside each of the connecting bottom blocks 8, and special-shaped sliding blocks 14 are slidably connected inside the sliding grooves. Inner clamping plates 3 are fixedly connected to the tops of the special-shaped sliding blocks 14.

[0029] Activity grooves are provided inside each of the inner clamping plates 3, and connecting rods 9 are fixedly connected inside the activity grooves. Two articulated sliding blocks 10 are slidably sleeved on the outer walls of the connecting rods 9. One ends of two transmission rods 11 are articulated inside the two articulated sliding blocks 10 respectively, and the other ends of the transmission rods 11 are articulated with an articulated block 12. The outer wall of an inner protective ring 4 is fixedly connected to the inner wall of the articulated block 12.

[0030] The inner walls of the special-shaped sliding blocks 14 are threadedly connected with threaded rods 13. One ends of the threaded rods 13 are movably sleeved inside the connecting bottom blocks 8.

[0031] By rotating the threaded rods 13, the special-shaped sliding blocks 14 on their surfaces are driven to rotate inside the connecting bottom blocks 8, thereby driving the inner clamping plates 3 to move on the outer walls of the connecting bottom blocks 8. At the same time, the movement of the inner clamping plates 3 drives the two articulated sliding blocks 10 to slide on the outer walls of the connecting rods 9, causing the transmission rods 11 to be articulated and rotated with the articulated block 12 as the center, thereby supporting the inner clamping plates 3 and making the inner clamping plates 3 fit more closely to the surface of the hose, thus avoiding water leakage.

[0032] The transmission mechanism includes bevel gears 5. The other ends of the threaded rods 13 are fixedly connected to the inner walls of the bevel gears 5. A number of toothed plates 6 are meshed with the outer walls of the bevel gears 5. Connecting rings 7 are fixedly connected to the opposite sides of the toothed plates 6. The tops of the connecting rings 7 are fixedly connected to the inner walls of the adjusting rings 2.

[0033] When the adjusting ring 2 is rotated, the adjusting ring 2 drives the internal connecting ring 7 to rotate synchronously, thereby making the toothed plates 6 mesh with the bevel gears 5, further driving the threaded rods 13 inside the bevel gears 5 to rotate inside the connecting bottom blocks 8, thereby driving multiple groups of inner clamping plates 3 to fix the hose synchronously. When the inner diameters of the hoses to be connected at both ends are inconsistent, one of the outer protective rings 1 can be rotated to adapt to hoses with different thicknesses of inner diameters.

[0034] Limiting rings 15 are fixedly connected to the outer walls of the two outer protective rings 1. The outer walls of the limiting rings 15 are movably sleeved inside the adjusting rings 2.

[0035] When the adjusting ring 2 rotates, it slides on the outer wall of the limiting ring 15 to maintain the stability when the adjusting ring 2 rotates. The two limiting rings 15 limit the adjusting ring 2 and at the same time prevent gaps from generating between the two connecting bottom blocks 8, thus avoiding leakage.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
