Description

Technical Field

[0001] The utility model relates to the technical field of oil delivery hoses, in particular to an antistatic oil delivery hose. Background Art

[0002] Oil hose is a soft pipe used to transport liquids or gases (such as oil, water, chemicals, etc.), usually made of rubber, plastic, metal and other materials. Oil hose is usually used in oil pipeline systems in the industrial field. It can connect oil tanks, oil pumps, oil tanks and other equipment to transport oil products to where they are needed.

[0003] In order to discharge internal static electricity, some existing oil hoses usually have metal wires directly sheathed on the surface of the hoses. Since the metal wires are in direct contact with the external environment, they are easily damaged, which reduces the service life. In addition, when connecting two hoses of this type of oil hose, multiple bolts need to be screwed together, which is troublesome.

[0004] Therefore, those skilled in the art provide an antistatic oil delivery 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 an antistatic oil delivery hose, which protects the metal wire by providing an outer layer, thereby increasing the service life of the metal wire, and when the outer layer is damaged, the outer layer can be replaced, and by providing a first fixing mechanism and a second fixing mechanism, it is not necessary to rotate multiple bolts when connecting two hoses, which is more convenient.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an antistatic oil delivery hose, comprising an inner layer, a first fixing ring, a first fixing mechanism, two second fixing mechanisms, a metal wire, four arc-shaped plates and two outer layers, wherein the second fixing mechanism comprises a second fixing ring, two fixing blocks and two arc-shaped blocks, a first return spring is fixedly arranged between the two arc-shaped blocks and the two fixing blocks, and the two outer layers comprise two conductive layers, two heat-insulating layers, two waterproof layers and two wear-resistant layers;

[0007] The two second fixing mechanisms include two third fixing rings, two sliding grooves, two slide plates and four limit blocks. Multiple positioning rods are fixedly arranged on the inner walls on the opposite sides of the two sliding grooves. The outer end surfaces of the multiple positioning rods are fixedly sleeved with rubber. Four second return springs are fixedly arranged between the two slide plates and the two sliding grooves.

[0008] Through the above technical scheme, the metal wire is wrapped by the outer layer. When in use, the static electricity generated inside the inner layer is absorbed by the metal wire, and then the static electricity is directed to the outside by the conductive layer, and by arranging a heat insulating layer, a waterproof layer and a wear-resistant layer at the outer end of the conductive layer, the service life is further improved. When the outer layer is damaged, the slide plate is moved manually. During the movement, the inner wall of the slide plate is sleeved on the outer end surface of the rubber, so that the slide plate is simply fixed, and then the same operation is performed on the other slide plate. At this time, the arc plate can be removed, and the first fixing ring is held to fit the end surface of the second fixing ring of the other hose, and then the first fixing ring is held while moving downward. At this time, the protrusion on the surface of the first fixing ring enters into the inner wall of the fixing block. During the entry process, the protrusion squeezes the arc block. When the protrusion is fully entered, the arc block enters into the inner wall of the protrusion under the action of the first reset spring, thereby fixing the two hoses together.

[0009] Furthermore, the first fixing ring fixing sleeve is arranged on the front side of the outer end surface of the inner layer, and the second fixing ring fixing sleeve is arranged on the rear side of the outer end surface of the inner layer;

[0010] Through the above technical solution, by providing the first fixing ring and the second fixing ring, the two hoses can be conveniently fixed together.

[0011] Furthermore, the two fixing blocks are respectively embedded in the end surfaces on both sides of the second fixing ring, and the two arc-shaped blocks are respectively penetrated and slidably arranged on the inner walls on the opposite sides of the two fixing blocks;

[0012] Through the above technical solution, the arc block is limited by the fixed block, so that the arc block is more stable when pushed by the first return spring.

[0013] Furthermore, the metal wire is fixedly sleeved on the outer end surface of the inner layer, the two third fixing rings are respectively fixedly sleeved on the front and rear sides of the outer end surface of the inner layer, the four arc-shaped plates are respectively clamped with the two third fixing rings, and the two outer layers are respectively fixedly connected with the four arc-shaped plates;

[0014] Through the above technical solution, the lower end of the metal wire is fixedly sleeved on the surface of the inner layer, and the upper end of the metal layer contacts the outer layer, so that the static electricity of the inner layer can be directed to the outside, and the fitting positions of the two outer layers here are bonded together by an adhesive.

[0015] Furthermore, the two heat-insulating layers are respectively fixedly arranged on the end surfaces on the opposite side of the two conductive layers, the two waterproof layers are respectively fixedly arranged on the end surfaces on the opposite side of the two heat-insulating layers, and the two wear-resistant layers are respectively fixedly arranged on the end surfaces on the opposite side of the two waterproof layers;

[0016] Through the above technical solution, the service life of the outer layer is increased by providing a wear-resistant layer, the external moisture can be prevented from entering the interior by providing a waterproof layer, and the inner layer can be prevented from expanding by the heat-insulating layer.

[0017] Furthermore, the two sliding grooves are respectively provided on the outer end surfaces of the two third fixing rings, and the two sliding plates are respectively slidably arranged on opposite sides of the inner bottom surfaces of the two sliding grooves;

[0018] Through the above technical solution, the sliding plate is limited by the sliding groove, so that the sliding plate is more stable when moving.

[0019] Furthermore, soft cloth is fixedly arranged at the upper side between the two slide plates and the two sliding grooves, and the four limit blocks are fixedly connected to the two third fixing rings respectively;

[0020] Through the above technical solution, the arc plate is limited by the limiting block so that it can cooperate with the protrusions on the surface of the skateboard, and the arc plate and the third fixing ring can be fixed together.

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

[0022] 1. The utility model proposes an antistatic oil hose, which can guide the static electricity inside the inner layer to the outside by providing a conductive layer and a metal wire, thereby improving the antistatic property of the oil hose, and by providing multiple interlayers, the service life of the outer layer is increased. When the outer layer is damaged, the slide plate is moved so that the inner wall of the slide plate slides to the surface of the rubber, thereby fixing the slide plate between multiple positioning rods, and then the same operation is performed on another slide plate, at this time, the two arc plates on the upper side can be moved upward, and the two arc plates on the lower side can be moved downward, thereby replacing the outer layer.

[0023] 2. The utility model proposes an antistatic oil delivery hose, which is moved by holding a first fixing ring so that the first fixing ring fits with the second fixing ring of another hose, and then the first fixing ring is held and moved downward. During the movement, the protrusion on the surface of the first fixing ring abuts against the arc block in the inner wall of the fixing block. When it cannot be pushed in further, the arc block is pushed into the inner wall of the protrusion under the action of the first return spring, thereby fixing the two hoses together. By setting the first fixing mechanism and the second fixing mechanism, it is more convenient to connect the two hoses without turning multiple bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-6 The utility model provides an embodiment: an antistatic oil delivery hose, comprising an inner layer 1, a first fixing ring 2, a first fixing mechanism 3, two second fixing mechanisms 4, a metal wire 5, four arc plates 6 and two outer layers 7, the second fixing mechanism 4 comprises a second fixing ring 301, two fixing blocks 302 and two arc blocks 303, a first return spring 304 is fixedly arranged between the two arc blocks 303 and the two fixing blocks 302, the first fixing ring 2 is fixedly sleeved on the front side of the outer end surface of the inner layer 1, the second fixing ring 301 is fixedly sleeved on the rear side of the outer end surface of the inner layer 1, the two fixing blocks 302 are respectively embedded in the end surfaces on both sides of the second fixing ring 301, and the two arc blocks 303 are respectively penetrated and slidably arranged on the inner walls of the opposite sides of the two fixing blocks 302.

[0034] By holding the first fixing ring 2 and fitting it against the end face of the second fixing ring 301 of the other hose, and then holding the first fixing ring 2 while moving downward, the protrusion on the surface of the first fixing ring 2 enters into the inner wall of the fixing block 302. During the entry process, the protrusion squeezes the arc block 303. When the protrusion is fully entered, the arc block 303 enters into the inner wall of the protrusion under the action of the first return spring 304, thereby fixing the two hoses together. When the connection between the two hoses is opened, the raised ends on the surfaces of the two arc blocks 303 are manually moved to the middle position, thereby driving the two arc blocks 303 to move in the inner walls of the two fixing blocks 302. At this time, the first fixing ring 2 can be held and moved upward, thereby releasing the fixation of the two hoses.

[0035] The two outer layers 7 include two conductive layers 701, two heat-insulating layers 702, two waterproof layers 703 and two wear-resistant layers 704. The metal wire 5 is fixedly sleeved on the outer end surface of the inner layer 1. The two third fixing rings 401 are respectively fixedly sleeved on the front and rear sides of the outer end surface of the inner layer 1. The four arc-shaped plates 6 are respectively clamped with the two third fixing rings 401. The two outer layers 7 are respectively fixedly connected with the four arc-shaped plates 6. The two heat-insulating layers 702 are respectively fixedly arranged on the end surfaces on the opposite sides of the two conductive layers 701. The two waterproof layers 703 are respectively fixedly arranged on the end surfaces on the opposite sides of the two conductive layers 701. The two heat-insulating layers 702 are respectively fixed on the end faces on the opposite sides, and the two wear-resistant layers 704 are respectively fixed on the end faces on the opposite sides of the two waterproof layers 703. The wear-resistant layers 704 are provided to increase the service life of the outer layer 7. The waterproof layers 703 are provided to prevent external moisture from entering the interior, and the heat-insulating layers 702 are used to prevent the inner layer 1 from expanding. The lower end of the metal wire 5 is fixedly sleeved on the surface of the inner layer 1, and the upper end of the metal layer contacts the outer layer 7, so that the static electricity of the inner layer 1 can be directed to the outside.

[0036] The two second fixing mechanisms 4 include two third fixing rings 401, two sliding grooves 402, two slide plates 405 and four limit blocks 408. A plurality of positioning rods 403 are fixedly arranged on the inner walls on the opposite side of the two sliding grooves 402. The outer end surfaces of the plurality of positioning rods 403 are fixedly sleeved with rubber 404. Four second return springs 406 are fixedly arranged between the two slide plates 405 and the two sliding grooves 402. The two sliding grooves 402 are respectively opened on the outer end surfaces of the two third fixing rings 401. The two slide plates 405 are respectively slidably arranged on the opposite side of the inner bottom surfaces of the two sliding grooves 402. Soft cloth 407 is fixedly arranged on the upper side between the two slide plates 405 and the two sliding grooves 402. The four limit blocks 408 are respectively fixedly connected to the two third fixing rings 401.

[0037] When the outer layer 7 is damaged, the slide plate 405 is moved manually. During the movement, the inner wall of the slide plate 405 is sleeved on the outer end surface of the rubber 404, so as to simply fix the slide plate 405. Then the same operation is performed on the other slide plate 405, thereby releasing the fixation of the four curved plates 6. At this time, one curved plate 6 can be held and moved upward. During the movement of this curved plate 6, the joint between the upper outer layer 7 and the lower outer layer 7 is torn apart, thereby releasing the fixation of the two outer layers 7. Then the new outer layer 7 is held and re-sleeved on the surface of the metal wire 5. Before sleeved, adhesive is first applied to the joint of the two outer layers 7. After the two outer layers 7 are in place, the two slide plates 405 are moved to their original positions again.

[0038] Working principle: When in use, manually hold the first fixing ring 2 and fit it on the surface of another third fixing ring 401, then hold the first fixing ring 2 and move it downward. During the movement, the convex block on the surface of the first fixing ring 2 abuts against the arc block 303. When it cannot be pushed in further, the arc block 303 is pushed into the inner wall of the convex block by the first return spring 304. When the outer layer 7 is damaged, manually hold the front slide 405 and move it to the front side for a distance, then manually hold the rear slide 405 and move it to the rear side for a distance. At this time, the two outer layers 7 can be removed, and then apply adhesive at the joint of the new outer layers 7. At this time, the two outer layers 7 are put on the surface of the metal wire 5, and finally the two slides 405 are moved back to their original positions.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
