Description

Technical Field

[0001] The utility model relates to the technical field of rubber hoses, in particular to a corrosion-resistant PU rubber hose. Background Art

[0002] As we all know, corrosion-resistant PU (polyurethane) hoses are widely used in industry, chemical industry, medical and other fields, and are favored for their superior corrosion resistance, wear resistance and flexibility.

[0003] The existing corrosion-resistant PU hose has a poor buffering and shock-absorbing effect. When the hose is hit by external objects or falls, it is easy to be damaged, which can easily lead to damage to the hose. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the utility model provides a corrosion-resistant PU hose.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a corrosion-resistant PU hose, comprising a body, a connecting block, a groove, a block and a connecting mechanism, the connecting block being arranged on the body, a cavity being opened inside the body, the groove being opened on the connecting block, an opening being opened at one end of the inner wall of the groove, the opening being communicated with the cavity, the block being connected to the inner wall of the groove through the connecting mechanism, the connecting mechanism comprising a threaded column, a nut, a slide groove and a slider, one end of the threaded column being connected to the inner wall of the groove, the other end of the threaded column extending into the block, the nut being threadedly connected to the threaded column, one end of the nut abutting against the block, the slide groove being opened on the inner wall of the groove, one end of the slider being slidably connected to the slide groove, the other end of the slider partially extending into the nut, and a plurality of buffer particles being provided inside the cavity.

[0008] In order to improve the buffering effect, the present invention has an improvement in that the buffer particles are made of silica gel.

[0009] In order to prevent the threaded column and the nut from rusting after long-term use, in order to solve this problem, in this embodiment, the threaded column and the nut are both made of stainless steel.

[0010] In order to achieve the flame retardant effect, the present invention is improved in that a flame retardant layer is provided inside the body, and the flame retardant layer is fixedly connected to the inside of the body.

[0011] (3) Beneficial effects

[0012] Compared with the existing technology, the utility model provides a corrosion-resistant PU hose with the following beneficial effects:

[0013] This corrosion-resistant PU hose has cushioning particles arranged in the cavity opened inside the main body, which can improve the cushioning and shock-absorbing effect of the main body. When the main body is hit by external objects or falls to the ground, the cushioning particles can absorb part of the energy and reduce the stress on the outer wall of the hose, thereby reducing the chance of the main body being damaged. When the cushioning particles are used for a long time and become aged and the cushioning effect is lost and they need to be replaced, the connecting mechanism is controlled so that the blocks no longer block the opening, and the cushioning particles in the cavity opened on the main body can be poured out and replaced with new cushioning particles.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4, a corrosion-resistant PU hose, including a body 1, a connecting block 2, a groove 3, a block 4 and a connecting mechanism 5, the connecting block 2 is arranged on the body 1, a cavity is opened inside the body 1, the groove 3 is opened on the connecting block 2, one end of the inner wall of the groove 3 is opened with an opening, the opening is communicated with the cavity, the block 4 is connected to the inner wall of the groove 3 through the connecting mechanism 5, the connecting mechanism 5 includes a threaded column 6, a nut 7, a slide 8 and a slider 9, one end of the threaded column 6 is connected to the inner wall of the groove 3, the other end of the threaded column 6 extends into the block 4, the nut 7 is threadedly connected to the threaded column 6, one end of the nut 7 abuts against the block 4, the slide 8 is opened on the inner wall of the groove 3, one end of the slider 9 is slidably connected to the slide 8, and the other end of the slider 9 partially extends into the nut 7, and a plurality of buffer particles are provided inside the cavity.

[0021] When in use, the main body 1 is a conventional corrosion-resistant PU hose on the market, which is not described in detail here. Buffer particles are set in the cavity opened inside the main body 1, which can improve the buffering and shock-absorbing effect of the main body 1. When the main body 1 is hit by external objects or the main body 1 falls to the ground, the buffer particles can absorb part of the energy and reduce the stress on the outer wall of the hose, thereby reducing the chance of the main body 1 being damaged. The buffer particles are a conventional technology on the market and are not described in detail here. When the buffer particles are used for a long time and need to be replaced, first push the slider 9 on the slide 8 with force to separate the slider 9 from the nut 7. The slider 9 is made of damping material and has a strong damping effect, so it needs to be pushed with force. Then screw the nut 7 to move the nut 7 on the threaded column 6 so that the nut 7 moves to the appropriate position and no longer contacts one end of the block 4. Then push the block 4. Make the block 4 move along the threaded column 6. A circular hole is provided on the block 4, and the threaded column 6 extends into the circular hole, but the threaded column 6 is not threadedly connected to the circular hole. The size of the circular hole is larger than the size of the threaded column 6, so that the block 4 can move on the threaded column 6 on the inner wall of the groove 3 opened on the connecting block 2. After the block 4 is pushed to the appropriate position, the opening opened on the inner wall of the groove 3 will be leaked, and then the opening will be tilted down. By adjusting the angle of the main body 1 by the staff, the buffer particles in the cavity opened on the main body 1 can be poured out, and then replaced with new buffer particles. The new buffer particles can be purchased from the manufacturer. The buffer particles in this structure are arranged in the cavity opened in the main body 1. The thickness of the cavity will not be very thick, which will not affect the use effect of the buffer particles. The size and shape of all components in this structure are not specifically limited here, and need to be produced according to actual conditions.

[0022] The above-mentioned buffer particles can be made of any material. In order to improve the buffering effect, in this embodiment, the buffer particles are made of silica gel.

[0023] The threaded column 6 and the nut 7 are prone to rust after long-term use. In order to solve this problem, in this embodiment, the threaded column 6 and the nut 7 are both made of stainless steel.

[0024] The flame retardant effect of the above-mentioned main body 1 is relatively poor. In order to solve this problem, in this embodiment, a flame retardant layer is provided inside the main body 1 , and the flame retardant layer is fixedly connected to the inside of the main body 1 .

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
