Description

Technical Field

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

[0002] When transporting a small amount of gasoline, rubber hoses are usually used. They can easily drag the pipeline, making it easier to add and inject it into other containers. Therefore, rubber pipes are usually used in various common gas stations and other places where fuel needs to be regulated and transported. However, the rubber pipe is a combination device with various supporting structures inside.

[0003] However, in actual use, the rubber tube needs to be manually stored again after being temporarily unfolded for use, and the traditional rubber pipe is usually straight, so it needs to be manually unwound and stored at one time, which is not convenient enough. At the same time, the size of the winding center of the traditional storage and winding device is usually relatively fixed, so the pipe that can be wrapped around its outer wall during use is relatively fixed, and it cannot be adjusted according to the actual length of use. Utility Model Content

[0004] The utility model aims to provide an antistatic oil delivery hose, which solves the problems that the existing manual winding is inconvenient and the winding radius is relatively fixed and cannot be adjusted according to needs.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an antistatic oil delivery hose, comprising a spiral tube, a winding tube and a mounting plate, wherein the spiral tube is spiral-shaped, and a winding tube is arranged at the spiral center of the spiral tube, one end of the winding tube is fixedly connected to the mounting plate, a screw rod is arranged through the interior of the winding tube, and a plurality of extrusion plates are arranged around the side wall of the winding tube;

[0006] A spiral tube for conveying is spirally connected with a spiral sheet on one side close to the winding tube, and one end of the spiral tube is fixedly connected to the inside of the mounting plate through a connecting tube;

[0007] Both ends of the screw rod used for rotation are connected to sliders at both ends near the extrusion plate through rotation, and the sliders are slidably connected to the inside of the winding tube;

[0008] The top and bottom of the extrusion plate used for extrusion are inclined toward the center at one end close to the inside of the winding tube. Slide grooves are provided at corresponding positions of the outer wall of the winding tube and the extrusion plate. One end of the extrusion plate is slidably connected to the side wall of the mounting plate.

[0009] Preferably, the spiral tube is made of rubber, an antistatic layer is provided inside the spiral tube, and the spiral sheet is made of plastic, and a spiral elastic iron wire is provided running through the inside of the spiral sheet.

[0010] Preferably, one end of the screw rod is rotatably connected to the center of the mounting plate via a bearing, one end of the screw rod away from the mounting plate is fixedly connected to a knob, and both ends of the screw rod are provided with threads in opposite directions.

[0011] Preferably, the interior of the winding tube is rhombus-shaped, and the outer wall of the sliding block at a side away from the extrusion plate is slidably connected to the inner wall of the winding tube.

[0012] Preferably, the extrusion plate is slidably connected to each other inside the slide groove of the side wall of the winding tube, the top and bottom inclined surfaces of the extrusion plate are in contact with the side edges of the slider, and the edge of the side wall of the slider is provided with an inclined surface corresponding to the side wall of the extrusion plate.

[0013] Preferably, a plurality of through holes are provided inside the side wall at one end of the winding tube away from the mounting plate, and a blocking rod is installed inside the through hole, and the side wall at one end of the spiral tube and the blocking rod are fitted to block each other.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. When the pulling stops, the spiral piece can be automatically recovered, thereby driving the spiral tube to be tightened. At the same time, since one end of the spiral tube is fixed to the mounting plate, the spiral tube can be recovered to one end of the mounting plate and automatically stored. The contraction force of the spiral piece can also assist in better winding and storage by humans. Moreover, when the spiral tube is not fixed to the connecting tube of the mounting plate, the blocking rod on the outer wall of the winding tube can be rotated, and the rotation of the blocking rod drives the winding tube to rotate, so that the spiral tube can be stored by rotation, and the spiral tube can be moved to the outer wall of the winding tube, and the storage can be completed without manually pulling the spiral tube.

[0016] 2. Turn the knob to make the knob rotate, which drives the lead screw and the slider to rotate relative to each other. At the same time, since the slider and the inner wall of the winding tube are slidably connected to each other and cannot rotate, the threads at both ends of the lead screw are in opposite directions, so that the slider can be driven to approach each other while the lead screw rotates, and the extrusion plate can be squeezed through the inclined surface of the side wall of the slider, so that the extrusion plate and the mounting plate slide against each other, and the extrusion plate moves away from the inner wall of the winding tube, thereby squeezing the spiral sheet, and then the winding radius of the spiral tube is expanded. When the slider does not squeeze the extrusion plate, the extrusion plate can move toward the inner wall of the winding tube under the winding of the spiral sheet, thereby reducing the winding radius.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-5 The antistatic oil delivery hose shown comprises a spiral tube 1, a winding tube 2 and a mounting plate 3. The spiral tube 1 is spiral, and a winding tube 2 is arranged at the spiral center of the spiral tube 1. One end of the winding tube 2 is fixedly connected to the mounting plate 3. A screw rod 4 is arranged inside the winding tube 2, and a plurality of extrusion plates 5 are arranged around the side wall of the winding tube 2. The spiral tube 1 used for transportation is spirally connected to a spiral sheet 101 on one side close to the winding tube 2, and one end of the spiral tube 1 is fixedly connected to the inside of the mounting plate 3 through a connecting tube 301. Both ends of the screw rod 4 used for rotation are connected to sliders 402 at both ends of the extrusion plate 5 by rotation, and the slider 402 is slidably connected to the inside of the winding tube 2. The top and bottom of the end of the extrusion plate 5 used for extrusion close to the inside of the winding tube 2 are inclined toward the center, and the outer wall of the winding tube 2 and the corresponding positions of the extrusion plate 5 are provided with slide grooves 501, and one end of the extrusion plate 5 is slidably connected to the side wall of the mounting plate 3.

[0027] like Figure 1 , Figure 5As shown, the spiral tube 1 is made of rubber, an antistatic layer is arranged inside the spiral tube 1, and the spiral piece 101 is made of plastic. A spiral elastic iron wire is arranged inside the spiral piece 101. When the spiral tube 1 is pulled, the spiral piece 101 is extended, and when the pulling stops, the spiral piece 101 can be automatically recovered, thereby driving the spiral tube 1 to be tightened. At the same time, since one end of the spiral tube 1 is fixed to the mounting plate 3, the spiral tube 1 can be recovered to one end of the mounting plate 3 and automatically stored. The contraction force of the spiral piece 101 can also assist in better winding and storage by humans.

[0028] like Figure 3 , Figure 4 As shown, one end of the screw rod 4 is rotatably connected to the center of the mounting plate 3 through a bearing, and the end of the screw rod 4 away from the mounting plate 3 is fixedly connected to a knob 401, and both ends of the screw rod 4 are provided with threads in opposite directions. The interior of the winding tube 2 is rhombus-shaped, and the outer wall of the slider 402 is slidably connected to the inner wall of the winding tube 2 on the side away from the extrusion plate 5, and the extrusion plate 5 is slidably connected to the inside of the slide groove 501 on the side wall of the winding tube 2. The top and bottom inclined surfaces of the extrusion plate 5 fit the side of the slider 402, and the edge of the side wall of the slider 402 is provided with a screw thread that fits the extrusion plate 5. The inclined surface corresponding to the side wall of the plate 5 is used to rotate the knob 401, thereby causing the knob 401 to rotate, driving the screw rod 4 and the slider 402 to rotate relative to each other. At the same time, since the slider 402 and the inner wall of the winding tube 2 are slidably connected to each other and cannot rotate, the threads at both ends of the screw rod 4 are reversed, and the slider 402 can be driven to approach each other while the screw rod 4 rotates, and then the extrusion plate 5 can be squeezed through the inclined surface of the side wall of the slider 402, so that the extrusion plate 5 and the mounting plate 3 slide against each other, and then the extrusion plate 5 is away from the inner wall of the winding tube 2, thereby realizing the extrusion of the spiral sheet 101.

[0029] like Figure 1 , Figure 2 As shown, a plurality of through holes 201 are penetrated inside the side wall of one end of the winding tube 2 away from the mounting plate 3, and a blocking rod 202 is installed inside the through hole 201, and the side wall of one end of the spiral tube 1 fits against the blocking rod 202 to block each other. When the spiral tube 1 is not fixed to the connecting tube 301 of the mounting plate 3, the blocking rod 202 on the outer wall of the winding tube 2 can also be rotated, and the rotation of the blocking rod 202 drives the winding tube 2 to rotate, so that the spiral tube 1 can be stored through the rotating winding tube 2, thereby realizing the movement of the spiral tube 1 toward the outer wall of the winding tube 2, and the storage can be completed without manually pulling the spiral tube 1.

[0030] Working principle: When in use, one end of the spiral tube 1 can be easily pulled to drive it to move, so that it can be conveniently pulled to different positions to connect and transport liquids. At the same time, since the spiral tube 1 is spiral and a spiral piece 101 is arranged on one side of its interior, the spiral piece 101 is extended when the spiral tube 1 is pulled, and when the pulling stops, the spiral piece 101 can be automatically recovered, thereby driving the spiral tube 1 to tighten. At the same time, since one end of the spiral tube 1 is fixed to the mounting plate 3, it can be realized. The spiral tube 1 is recovered to one end of the mounting plate 3 and stored automatically. The contraction force of the spiral sheet 101 can also assist in better winding and storage by humans. Moreover, when the spiral tube 1 is not fixed to the connecting tube 301 of the mounting plate 3, the blocking rod 202 on the outer wall of the winding tube 2 can be rotated. The rotation of the blocking rod 202 drives the winding tube 2 to rotate, so that the spiral tube 1 can be stored through the rotating winding tube 2, thereby realizing the movement of the spiral tube 1 to the outer wall of the winding tube 2, and the storage can be completed without manually pulling the spiral tube 1.

[0031] When the winding radius needs to be adjusted for use, the knob 401 can be easily turned to make the knob 401 rotate and drive the screw rod 4 and the slider 402 to rotate relative to each other. At the same time, since the slider 402 and the inner wall of the winding tube 2 are slidably connected to each other and cannot rotate, the threads at both ends of the screw rod 4 are in opposite directions, and the slider 402 can be driven to approach each other while the screw rod 4 rotates, and the extrusion plate 5 can be squeezed through the inclined surface of the side wall of the slider 402, so that the extrusion plate 5 and the mounting plate 3 slide against each other, and then the extrusion plate 5 is away from the inner wall of the winding tube 2, thereby squeezing the spiral sheet 101, and then the winding radius of the spiral tube 1 is expanded, and then when the slider 402 does not squeeze the extrusion plate 5, the extrusion plate 5 can move toward the inner wall of the winding tube 2 under the winding of the spiral sheet 101, so as to reduce the winding radius.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
