Description

Technical Field

[0001] The utility model relates to the field of rubber devices, in particular to a novel sheathed rubber hose. Background Art

[0002] Rubber hose is a flexible and bendable tubular article, mainly composed of inner rubber layer, braided layer and outer rubber layer. It is widely used in conveying liquid, gas and other media due to its good elasticity and corrosion resistance. However, during use, rubber hose is often easily affected by the external environment, resulting in damage and cracking. The required sheath is made of wear-resistant and corrosion-resistant materials. The existence of the sheath not only effectively enhances the durability of the rubber hose, but also ensures that its safety and stability are fully guaranteed during use.

[0003] As for the current sheathed rubber hose, the rubber hose is usually composed of a three-layer structure, in which the increased strength of the single-layer steel wire braided layer often has certain limitations, which may have a certain impact on the overall quality of the hose. In addition, the sheath and the rubber hose are usually directly installed, and there is often no other fixing method. Although there is usually a certain friction between the sheath and the rubber hose, the friction is often small, and the sheath may slide along the hose for a distance, which may cause some hoses to not be effectively protected by the sheath.

[0004] Therefore, the utility model provides a novel sheath rubber hose to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a new type of sheathed rubber hose, in which a main body mechanism and a protective mechanism are provided to improve the toughness of the hose by increasing the braided layer, and at the same time the protective mechanism can fix the protective sheath to ensure effective protection of the sheath.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A novel sheath rubber hose comprises a main body mechanism and a protection mechanism, wherein the main body mechanism comprises an inner rubber layer, a middle rubber layer and an outer rubber layer, a No. 1 braided layer is fixedly arranged between the inner rubber layer and the middle rubber layer, a No. 2 braided layer is fixedly arranged between the middle rubber layer and the outer rubber layer, and comprises a spiral protective sleeve, two threaded blocks and two fixed blocks, elastic limit blocks are slidably arranged on one side of the two threaded blocks, connecting blocks are fixedly arranged on opposite sides of the two fixed blocks near the upper ends, a plurality of sliders are slidably arranged on the inner surfaces of the two fixed blocks, a rotating block is rotatably sleeved on the opposite sides of the two fixed blocks, a plurality of arc blocks are fixedly arranged on the inner surfaces of the two rotating blocks, and a plurality of limit posts are fixedly arranged on the opposite sides of the two rotating blocks;

[0008] Through the above technical scheme, the sheath rubber hose is provided with a main body mechanism and a protective mechanism. The main body mechanism is composed of three rubber layers and two braided layers alternatingly. The toughness of the rubber hose can be further improved while ensuring that the rubber thickness remains unchanged and the softness of the hose is not reduced. The rotation of the rotating block in the protective mechanism can adjust the position of the slider to adapt to the size of the hose orifice.

[0009] Furthermore, the main body mechanism is arranged inside the protection mechanism, and the two fixing blocks are respectively sleeved outside the outer rubber layer near the two ends;

[0010] Through the above technical solution, the protection mechanism is located outside the main mechanism, and the fixing block ensures the stability of the protection cover, thereby ensuring the protective effect of the protection cover.

[0011] Furthermore, one side of the two threaded blocks is fixedly connected to the other side of the two fixed blocks, and threads are fixedly arranged inside the two threaded blocks.

[0012] Through the above technical solution, the threaded block is fixedly connected to the hose through the fixing block, and at the same time, the threaded connection of the hose with other methods can be ensured.

[0013] Furthermore, one side of the outer surface of the two threaded blocks is provided with a pressing groove, and the two elastic limit blocks are respectively slidably sleeved in the two pressing grooves;

[0014] Through the above technical solution, the push groove ensures the sliding of the elastic limit block, and the internal spring structure ensures the back and forth sliding of the limit block.

[0015] Furthermore, the spiral protective sleeve is sleeved on the outside of the main body mechanism, and the two ends of the spiral protective sleeve are fixedly connected to the two connecting blocks respectively;

[0016] Through the above technical solution, the spiral protective sleeve is a spiral and slightly elastic belt-like structure, and the protective sleeve can be manually wrapped around the outside of the hose.

[0017] Furthermore, one side of each of the plurality of sliders opposite to each other is fixedly provided with an adjusting spring, and one side of each of the plurality of adjusting springs opposite to each other is fixedly connected to two fixing blocks respectively;

[0018] Through the above technical solution, the adjustment spring can generate a certain force on the slider, and adjust the position of the slider together with the arc block.

[0019] Furthermore, the plurality of arc blocks correspond to the positions of the plurality of sliders respectively, and the two elastic limit blocks are both clamped with the corresponding limit columns;

[0020] Through the above technical solution, the arc block can push the corresponding sliding block to slide, and the clamping action between the limit block and the limit column can control the state of the rotating block.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a new type of sheathed rubber hose, in which a main body structure is provided. During use, the main body structure is provided with three rubber layers and two braided layers, which not only ensures that the softness of the rubber hose is not affected, but also effectively improves the strength of the rubber hose through the alternating arrangement of the rubber layer and the braided layer. This design enables the rubber hose to maintain its original softness while enhancing its toughness, thereby improving the overall performance.

[0023] 2. The utility model proposes a novel sheathed rubber hose, in which a protective mechanism is arranged. During use, the fixed blocks in the protective mechanism are respectively sleeved on both ends of the hose. At the same time, the rotating block can accurately adjust the position of the slider through a flexible rotating mechanism, so as to achieve a stable connection between hoses of different thicknesses and the fixed block. The fixed block stably sleeves the protective cover on the outside of the hose, effectively preventing possible relative displacement between the hose and the protective cover, thereby ensuring that the protective cover provides effective protection for the hose.

[0034] The sheath rubber hose is provided with a main body 1, which is the part of the hose. The inner rubber layer 101, the middle rubber layer 103 and the outer rubber layer 105 are tubular structures made of rubber material. The first braided layer 102 and the second braided layer 104 are steel wire braided layers located between adjacent rubber layers, which can improve the strength of the rubber hose while ensuring the softness of the rubber hose. The alternating combination of three rubber layers and two braided layers can further improve the toughness of the rubber hose.

[0035] The protection mechanism 2 includes a spiral protection sleeve 201, two threaded blocks 202 and two fixed blocks 205. An elastic limit block 203 is slidably provided on one side of the two threaded blocks 202. A connecting block 206 is fixedly provided near the upper end of the opposite side of the two fixed blocks 205. A plurality of sliders 207 are slidably provided on the inner surfaces of the two fixed blocks 205. A rotating block 209 is rotatably sleeved on the opposite side of the two fixed blocks 205. A plurality of arc blocks 210 are fixedly provided on the inner surfaces of the two rotating blocks 209. A plurality of limit posts 211 are fixedly provided on the opposite side of the two rotating blocks 209.

[0036] The opposite sides of the two threaded blocks 202 are fixedly connected to the opposite sides of the two fixed blocks 205, and the interiors of the two threaded blocks 202 are fixedly provided with threads, and one side of the outer surface of the two threaded blocks 202 is provided with a pressing groove 204, and the two elastic limit blocks 203 are respectively slidably sleeved in the two pressing grooves 204, and the two ends of the spiral protective sleeve 201 are respectively fixedly connected to the two connecting blocks 206, and the opposite sides of the multiple sliders 207 are fixedly provided with adjustment springs 208, and the opposite sides of the multiple adjustment springs 208 are respectively fixedly connected to the two fixed blocks 205, and the multiple arc blocks 210 correspond to the positions of the multiple sliders 207, and the two elastic limit blocks 203 are respectively engaged with the corresponding limit columns 211;

[0038] Working principle: When the user sets the protection mechanism 2 on the outside of the main mechanism 1, first press the elastic limit block 203 inward, the elastic limit block 203 and the limit column 211 release the limit clamping state, drive the rotating block 209, and the arc block 210 therein rotates synchronously, which can change the squeezing effect of the arc block 210 on the slider 207, adjust the end of the slider 207 located outside the fixed block 205 to the center position close to the fixed block 205, and then release the elastic limit block 203. Under the action of the spring, the limit block returns to its original position and forms a clamping limit state with the limit column 211;

[0039] Then insert one end of the hose into the fixed block 205, and then repeat the above process, rotate the rotating block 209, drive the arc block 210 to rotate, adjust the slider 207 to a suitable position, ensure that the two pairs of sliders 207 fix the hose stably in the fixed block 205 at one end, loosen the limit block, and fix the rotating block 209 stably at this angle to ensure the firmness of the fixation between the hose and the fixed block 205, then wrap the spiral protective sleeve 201 around the hose, and then stably connect the other end of the hose to another fixed block 205, thereby achieving effective protection of the hose by the sleeve.
