Description

Technical Field

[0001] This utility model relates to the field of hose installation technology for pipeline inspection, and in particular to a hose installation device. Background Technology

[0002] Filter tip resistance is a crucial indicator affecting the suction experience. When testing filter tip resistance, the filter tip is inserted into the testing tube of the testing device. A rubber tube is installed on the inner wall of the testing tube. When the filter tip is inserted, its outer circumference presses against the rubber tube to ensure the airtightness of the testing tube. The testing tube includes an inlet end and an outlet end. When installing the rubber tube, it is first inserted into the testing tube, with both ends of the tube outside the testing tube. Then, both ends of the tube are folded outwards so that they wrap around the inlet and outlet ends of the testing tube, respectively. In existing technology, rubber tube replacement and installation are all done manually. Manual installation is not only inefficient but also prone to damaging the rubber tube during the process. Utility Model Content

[0003] The purpose of this invention is to solve the technical problems of low installation efficiency and easy damage to rubber hoses. This invention provides a rubber hose installation device that can improve the installation efficiency of rubber hoses and reduce the breakage rate of rubber hoses.

[0004] To solve the above-mentioned technical problems, the present invention provides a hose installation device for attaching a hose to a testing pipeline, comprising:

[0005] The guide rod has a guide end at one end and a handheld end at the other end; the diameter of the guide rod is less than or equal to the diameter of the hose; multiple hinge pins are provided on the outer circumference of the guide rod, and the axis of the hinge pins is perpendicular to the axis of the guide rod.

[0006] Multiple expansion rods, equal in number and corresponding in position to the hinge pins, are provided. One end of each expansion rod is an expansion end, and the other end is a hinge end. Each hinge end is hinged to a respective hinge pin. The expansion rod can rotate around the hinge pin between a first position and a second position. When the expansion rod rotates to the first position, the maximum distance between the side of the expansion end facing away from the guide rod and the axis of the guide rod is less than or equal to the radius of the hose. When the expansion rod rotates to the second position, the maximum distance between the side of the expansion end facing away from the guide rod and the axis of the guide rod is greater than the radius of the hose.

[0007] Optionally, the guide rod is provided with a receiving groove, which is located near the guide end. When the expansion rod is rotated to the first position, each expansion end is located in the receiving groove.

[0008] Optionally, the receiving groove is an annular groove that surrounds the guide rod circumferentially; the expansion end is arc-shaped, with its inner diameter equal to the diameter of the bottom surface of the receiving groove, and its outer diameter less than or equal to the diameter of the guide end; when the expansion rod rotates to the first position, the inner wall of the expansion end fits against the bottom surface of the receiving groove.

[0009] Optionally, the expansion rod includes a first expansion rod and a second expansion rod, with two of each type. The two first expansion rods are arranged opposite each other, and the two second expansion rods are arranged opposite each other. The expansion end on each first expansion rod is closer to the guide end than the expansion end on each second expansion rod.

[0010] Optionally, it also includes a slider, which is sleeved on the guide rod and can slide along the guide rod. The slider is located between the hinge and the hand-held end. The expansion rod is provided with a connecting part, and an elastic element is provided between the slider and the connecting part. When the slider slides towards the side closer to the hand-held end, the slider applies a force to the expansion rod through the elastic element, so that the expansion rod rotates to a second position. When the slider slides towards the side closer to the guide end, the slider applies a force to the expansion rod through the elastic element, so that the expansion rod rotates to a first position.

[0011] Optionally, the elastic element is an arc-shaped elastic rod. When the slider slides towards the hand-held end, the elastic element can apply a pulling force to the connecting part; when the slider slides towards the guide end, the elastic element can apply a pushing force to the connecting part.

[0012] Optionally, the guide rod includes an action section, a connecting section, and an operating section connected sequentially from the guide end to the hand-held end, with both the action section and the operating section being threadedly connected to the connecting section; a receiving groove is provided on the action section, a hinge shaft is provided on the connecting section, and a slider is provided on the operating section.

[0013] Optionally, a connecting block is provided on the outer circumference of the connecting section, and the hinge shaft is inserted into the connecting block.

[0014] Optionally, the handheld end is provided with an operation panel, the diameter of which is larger than the diameter of the guide rod, and the slider is disc-shaped. The axes of the operation panel and the slider are both coincident with the axis of the guide rod.

[0016] Compared with the prior art, this utility model has the following beneficial effects:

[0017] In this embodiment, multiple expansion rods are hinged to the outer circumference of a guide rod. When a hose needs to be fitted, the guide end of the guide rod and the expansion end of the expansion rod are inserted into the hose. By applying external force to the expansion rod, the expansion end expands radially outward along the guide rod, thus expanding the inner diameter of the hose. This facilitates the outward folding of both ends of the hose so that the two ends of the hose respectively wrap around the inlet and outlet ends of the testing pipe, thereby easily fitting the hose onto the testing pipe. Compared to the prior art of manually pulling the hose, this application uses expansion rods to expand the inner diameter of the hose, which not only saves time and effort but also reduces the hose breakage rate.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] This utility model provides a hose installation device for attaching a hose 2 to a testing pipe 1. The hose installation device includes a guide rod 3 and multiple expansion rods 7.Figure 1 As shown, one end of the guide rod 3 is the guide end 4, and the other end is the handheld end 5. The diameter of the guide rod 3 is less than or equal to the diameter of the tubing 2, facilitating the guide end 4 to guide the expansion rod 7 into the tubing 2. Multiple hinge pins 6 are provided on the outer circumference of the guide rod 3, and the axes of the hinge pins 6 are perpendicular to the axis of the guide rod 3. The number of expansion rods 7 and hinge pins 6 are equal, and their positions correspond one-to-one. One end of the expansion rod 7 is the expansion end 8, and the other end is the hinge end 9. Each hinge end 9 is hinged to a respective hinge pin 6, allowing the expansion rod 7 to rotate between a first position and a second position around the hinge pin 6. When the expansion rod 7 rotates to the first position, as... Figure 2 As shown, the maximum distance between the side of the expansion end 8 facing away from the guide rod 3 and the axis of the guide rod 3 (e.g.) Figure 2 The dimension L1 shown in the figure is less than or equal to the radius of the tubing 2, so that it can be inserted into the tubing 2 when the expansion rod 7 is rotated to the first position. When the expansion rod 7 is rotated to the second position, as shown in the figure... Figure 3 As shown, the maximum distance between the side of the expansion end 8 facing away from the guide rod 3 and the axis of the guide rod 3 is ( Figure 3 The dimension L2 shown in the figure is larger than the radius of the tube 2. At this time, the expansion rod 7 can expand the radius of the tube 2 so that the tube 2 can be sleeved on the end of the tube 2.

[0031] When it is necessary to connect hose 2 to the detection pipe 1, first insert hose 2 into the detection pipe 1, and make both ends of hose 2 extend to the outside of the detection pipe 1, such as... Figure 1 As shown. Then, the expansion rod 7 is rotated to the first position, and both the guide end 4 and the expansion end 8 are inserted into the end of the hose 2. The operator then rotates the expansion rod 7 to the second position, so that the expansion end 8 expands the diameter of the hose 2, and the expanded diameter of the hose 2 is larger than the outer diameter of the port of the detection pipe 1, as shown. Figure 3 As shown. Then, push the entire hose installation device towards the detection pipe 1, causing the end of the hose 2 to fold outwards to the outer periphery of the end of the detection pipe 1, as shown. Figure 4 As shown. Because the hose 2 has an elastic force that contracts towards the center of the hose, the end of the hose 2 can wrap around the end of the detection pipe 1 under its own elastic force. Furthermore, under its own elastic force, the hose 2 disengages from the expansion end 8, completing the installation. Finally, the entire hose installation device is moved away from the detection pipe 1, and the expansion rod 7 is rotated to the first position to house the hose installation device.

[0032] Using the above technical solution, the operator can expand the inner diameter of the hose 2 using the hose installation device, making it easy to fold both ends of the hose 2 outwards so that the two ends of the hose 2 respectively wrap around the inlet and outlet ends of the detection pipe 1, thereby easily fitting the hose 2 onto the detection pipe 1. Compared with the prior art of manually pulling the hose 2, this application uses an expansion rod 7 to expand the inner diameter of the hose 2, which not only saves time and effort but also reduces the breakage rate of the hose 2.

[0033] Furthermore, such as Figures 1 to 4 As shown, the guide rod 3 is provided with a receiving groove 11, which is located near the guide end 4. When the expansion rod 7 rotates to the first position, each expansion end 8 is located within the receiving groove 11. When the expansion end 8 is located inside the receiving groove 11, the maximum distance between the side of the expansion end 8 facing away from the guide rod 3 and the axis of the guide rod 3 (e.g., ...) Figure 2 The radius of the expansion end 8 (as shown in the middle dimension L1) is less than or equal to that of the hose 2, so that the expansion end 8 can be inserted into the hose 2 when the expansion rod 7 is rotated to the first position. This prevents the expansion end 8 from protruding from the outer circumference of the guide rod 3 and avoids interference between the expansion end 8 and the end of the hose 2 when the hose 2 is inserted into the hose 2.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, the receiving groove 11 is an annular groove, surrounding the guide rod 3 circumferentially. The expansion end 8 is arc-shaped, with its inner diameter equal to the inner diameter of the receiving groove 11, and its outer diameter less than or equal to the diameter of the guide end 4. When the expansion rod 7 rotates to the first position, the inner wall of the expansion end 8 is in contact with the bottom surface of the receiving groove 11. The arc-shaped expansion end 8 increases the contact area between the expansion end 8 and the inner wall of the tubing 2, reducing the pressure of the expansion end 8 on the inner wall of the tubing 2 and preventing the expansion end 8 from puncturing the tubing 2. By setting the receiving groove 11 as an annular groove, it is easy for the expansion end 8 to be completely contained within the receiving groove 11 when it rotates to the first position, avoiding interference between the expansion end 8 and the end of the tubing 2 when it is inserted into the tubing 2.

[0035] Furthermore, such as Figure 1 As shown, the expansion rod 7 includes two first expansion rods 20 and two second expansion rods 21, with the two first expansion rods 20 and the two second expansion rods 21 arranged opposite each other. When each of the expansion rods 7 rotates to the first position, the two expansion ends 8 on the two first expansion rods 20 interlock to form a ring, and the two expansion ends 8 on the two second expansion rods 21 interlock to form a ring. The expansion ends 8 on each first expansion rod 20 are closer to the guide end 4 than the expansion ends 8 on each second expansion rod 21, so that the expansion ends 8 on the first expansion rod 20 and the expansion ends 8 on the second expansion rod 21 can be arranged along the axial direction of the guide rod 3 in the receiving groove 11, preventing interference between the expansion ends 8 during rotation.

[0036] Furthermore, such as Figure 1 and Figure 2 As shown, the hose installation device also includes a slider 12, which is sleeved on the guide rod 3 and can slide along the guide rod 3. The slider 12 is located between the hinge pin 6 and the handheld end 5. The expansion rod 7 is provided with a connecting part 10, and an elastic element 13 is provided between the slider 12 and the connecting part 10. Specifically, one end of the elastic element 13 is connected to the slider 12, and the other end is connected to the connecting part 10. When the slider 12 slides towards the side closer to the handheld end 5, the slider 12 applies a pulling force to the expansion rod 7 through the elastic element 13, so that each expansion rod 7 rotates simultaneously to the second position; when the slider 12 slides towards the side closer to the guide end 4, the slider 12 applies a pushing force to the expansion rod 7 through the elastic element 13, so that each expansion rod 7 rotates simultaneously to the first position. Specifically, the elastic element 13 is an arc-shaped elastic rod. When the slider 12 slides towards the side closer to the handheld end 5, the elastic element 13 can apply a pulling force to the connecting part 10; when the slider 12 slides towards the guide end 4, the elastic element 13 can apply a pushing force to the connecting part 10.

[0037] Furthermore, such as Figure 2 As shown, the guide rod 3 includes an action section 14, a connecting section 15, and an operating section 16 connected sequentially from the guide end 4 to the handheld end 5. Both the action section 14 and the operating section 16 are threadedly connected to the connecting section 15. A receiving groove 11 is provided on the action section 14, a hinge shaft 6 is provided on the connecting section 15, and a slider 12 is provided on the operating section 16. Specifically, a connecting block 17 is provided on the outer circumference of the connecting section 15, and the hinge shaft 6 is inserted into the connecting block 17. By designing the guide rod 3 as a three-section structure, it is convenient to separately machine the connecting block 17 and the hinge shaft 6 from the connecting section 15, and it also facilitates the assembly of the hose installation device by the manufacturer.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the handheld end 5 is equipped with an operation disc 18, the diameter of which is larger than the diameter of the guide rod 3. The slider 12 is disc-shaped, and the axes of both the operation disc 18 and the slider 12 coincide with the axis of the guide rod 3. When sliding the slider 12 toward the handheld end 5, the operator can simultaneously grasp the edges of the operation disc 18 and the slider 12 with both hands, squeezing them together to apply an external force that brings them closer together. When sliding the slider 12 toward the guide end 4, the operator can grasp the edges of the operation disc 18 and the slider 12 with both hands respectively to apply an external force that pushes them away from each other.

[0039] Furthermore, such as Figure 1As shown, a guide surface 19 is provided on the end face of the guide end 4. The diameter of the guide surface 19 gradually decreases along the direction from the handheld end 5 to the guide end 4. When the guide end 4 is inserted into the tube 2, the guide surface 19 can guide the guide end 4 into the tube 2, thereby improving the efficiency of use.

[0040] The hose installation device disclosed in this utility model achieves efficient installation and protection of hose 2 through mechanical linkage. Its working principle is as follows: First, the tapered guide end 4 of the guide rod 3 is inserted into hose 2. At this time, the expansion rod 7 is in the first position, and the expansion end 8 is housed in the annular receiving groove 11 of the guide rod 3, ensuring smooth entry of the device into hose 2. Then, the operator pulls the slider 12 towards the handheld end 5, applying tension to the expansion rod 7 through the arc-shaped elastic element 13, causing each expansion rod 7 to rotate towards the second position. During this process, multiple sets of arc-shaped expansion ends 8 simultaneously extend outward to expand the end of hose 2. When each expansion rod 7 rotates to the second position, the end of hose 2 expands uniformly to a size slightly larger than the outer diameter of the detection pipe 1 (e.g., ...). Figure 3 (As shown). With hose 2 in the expanded state, push the hose installation device toward the detection pipe 1, using the supporting force of the expansion end 8 to fold the end of hose 2 outwards to wrap around the edge of the pipe (as shown). Figure 4 (As shown); then continue pulling the slider 12 towards the handheld end 5 to disengage the expansion end 8 from the hose 2; then move the entire hose installation device away from the detection pipe 1. Finally, push the slider 12 towards the guide end 4 to reset and retract the expansion rod 7 to the first position to house the hose installation device. This process, through the coordinated control of the guide rod 3, slider 12, elastic element 13, and expansion rod 7, achieves an integrated operation of hose 2 expansion and outward turning, which not only avoids hose 2 damage caused by manual pulling but also significantly improves installation efficiency.

[0041] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
