Description

Technical Field

[0001] This application relates to the field of hose quality testing technology, specifically to a device for testing the abrasion resistance of hoses. Background Technology

[0002] Plastic hoses are widely used in various industrial and civilian fields, such as chemical, pharmaceutical, food processing, and automobile manufacturing. Although they have advantages such as being lightweight, flexible, and easy to install, in actual use, plastic hoses are subject to multiple influences from internal media and external environment. These factors may cause hose damage and leakage, which in turn affects the sealing and other performance of the entire system.

[0003] For example, hoses are easily subjected to collisions or friction from external objects during installation, handling, or use, resulting in surface scratches, dents, or even cracks. Wear resistance directly affects the service life and reliability of the hose.

[0004] Therefore, in order to ensure the wear resistance of hoses, wear resistance tests are required. However, existing wear resistance testing equipment often suffers from complex structures, inconvenient operation, and high costs, which not only increases the difficulty of testing but also limits its widespread application to some extent.

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The inventors, through analysis of existing technologies, discovered that current hose abrasion resistance testing equipment has overly complex mechanical structures, typically including multiple transmission mechanisms, loading devices, and positioning components. This not only increases the difficulty of assembly and maintenance but also makes it susceptible to errors in component coordination, affecting test accuracy. Furthermore, existing equipment often involves cumbersome operating procedures, requiring professional personnel to perform multiple steps of debugging and parameter setting, hindering rapid clamping and one-click testing, thus reducing testing efficiency. Therefore, there is an urgent need for an abrasion resistance testing device that is simple in structure, easy to operate, and low in cost.

[0021] Reference Figure 1-4This application illustrates an embodiment of an abrasion resistance testing device for hoses, comprising: a control component, a telescopic mechanism 1, a friction mechanism 2, and a base 3. The control component is electrically connected to the telescopic mechanism 1, and the movable end of the telescopic mechanism 1 is connected to the friction mechanism 2; the base 3 is provided with a slide rail 31, and the friction mechanism 2 is movably mounted on the slide rail 31; During testing, the tube body 5 to be tested is fixedly positioned between the friction mechanism 2 and the base 3, and the friction surface of the friction mechanism 2 is in contact with the outer wall of the tube body 5 to be tested; the control signal of the control component is transmitted to the telescopic mechanism 1, so that the telescopic mechanism 1 drives the friction mechanism 2 to reciprocate.

[0022] In the embodiments of this application, addressing the problems of complex structure, inconvenient operation, and high cost of existing wear resistance testing equipment, this application provides a solution for testing the wear resistance of hoses through reciprocating friction. Specifically, it includes: a control component, a telescopic mechanism 1, a friction mechanism 2, and a base 3. The control component is electrically connected to the telescopic mechanism 1, and the movable end of the telescopic mechanism 1 is connected to the friction mechanism 2. The base 3 is provided with a slide rail 31, and the friction mechanism 2 is movably mounted on the slide rail 31. During testing, the tube body 5 to be tested is fixedly positioned between the friction mechanism 2 and the base 3, with the friction surface of the friction mechanism 2 contacting the outer wall of the tube body 5. The control signal from the control component is transmitted to the telescopic mechanism 1, causing the telescopic mechanism 1 to drive the friction mechanism 2 to reciprocate. This application simulates a friction scenario by having the telescopic mechanism 1 drive the friction mechanism 2 to reciprocate against the outer wall of the tube body 5 under test, thus achieving the testing of the wear resistance of the tube body 5 under test. Furthermore, the structure is simple and the operation is convenient.

[0023] The following will further describe an abrasion resistance testing device for hoses in this exemplary embodiment.

[0024] It should be noted that the control component can be a personal computer; the control component can set and monitor the total number of reciprocating friction tests and the motion frequency; during the test, the pressure signal at the friction surface can be fed back to the control component through the pressure sensor built into the friction mechanism 2, which is convenient for simulating the usage environment under different pressures.

[0025] As an example, multiple test tubes 5 can be set between the friction mechanism 2 and the base 3 to enable simultaneous testing of multiple samples; the test tube 5 can be a flexible pipe with an outer wall that is prone to friction with the environment, such as a garden pipe.

[0026] In one embodiment of this application, the telescopic mechanism 1 includes: a cylinder 11 and a piston rod 12 connected thereto; One end of the piston rod 12 is movably disposed in the cylinder 11 along the axial direction of the cylinder 11; the other end of the piston rod 12 is connected to the friction mechanism 2.

[0027] It should be noted that during testing, the control component can drive the piston rod 12 to extend and retract within the cavity of the cylinder 11. The piston rod 12 provides thrust and pull to the friction mechanism 2, thereby realizing the reciprocating motion of the friction mechanism 2.

[0028] In one embodiment of this application, the cylinder 11 is disposed on the base 3, such that the piston rod 12 is coaxially disposed with the installation direction of the tube body 5 to be tested.

[0029] It should be noted that the above structure can ensure that the friction mechanism 2 connected to the piston rod 12 reciprocates along the axial direction of the tube body 5 to be tested, so as to test the wear resistance of the tube body 5 in the axial direction.

[0030] In one embodiment of this application, rollers 21 are respectively provided on both sides of the friction mechanism 2; the slide rail 31 includes a first guide rail 311 and a second guide rail 312; The friction mechanism 2 is tactilely connected to the first guide rail 311 and the second guide rail 312 respectively via the roller 21.

[0031] It should be noted that, since the friction mechanism 2 is mounted on the slide rail 31 via rollers 21 on both sides, the slide rail 31 must have the capacity to bear load in order to ensure its supporting function for the friction mechanism 2.

[0032] In one embodiment of this application, both the first guide rail 311 and the second guide rail 312 are provided with slides; the slides are arranged along the length direction of the first guide rail 311 and the second guide rail 312 and are inclined toward the base 3; the roller 21 is disposed inside the slide.

[0033] It should be noted that, through the above-mentioned customized slide design, the direction, angle and stroke of the friction mechanism 2 can be precisely controlled, thereby ensuring that the pressure between the friction mechanism 2 and the tube body 5 under test meets the test requirements.

[0034] As an example, the slide can be a regular or irregular curved structure to simulate different friction scenarios.

[0035] In one embodiment of this application, the rollers 21 disposed on the same side of the friction mechanism 2 include at least two.

[0036] It should be noted that the arrangement of multiple rollers 21 on the same side of the friction mechanism 2 can ensure the supporting effect of the slide rail 31 on the friction mechanism 2 and improve the stability of the reciprocating motion of the friction mechanism 2 during testing.

[0037] In an additional embodiment of this application, it also includes: a fastener 4; During testing, the tube to be tested 5 is positioned between the fixing member 4 and the base 3. The fixing member 4 is fixedly connected to the base 3 by screws 41, so that the tube to be tested 5 is clamped between the fixing member 4 and the base 3.

[0038] It should be noted that the fixing component 4 can ensure that the tube body 5 under test is stably and accurately installed on the base 3, preventing the tube body 5 under test from rotating or sliding axially or radially during testing, thereby ensuring the accuracy of the test results.

[0039] In one embodiment of this application, the fixing member 4 is provided with a pressing surface structure that is adapted to the shape of the outer wall of the tube body 5 to be tested; During testing, the pressing surface structure mates with the outer wall of the tube body 5 to be tested.

[0040] It should be noted that setting the pressing surface structure to a shape that adapts to the outer wall of the tube body 5 under test can increase the contact area between the pressing surface structure and the outer wall of the tube body 5 under test, and further prevent the tube body 5 under test from rotating and slipping during testing.

[0041] As an example, when the outer wall of the tube body 5 to be tested is cylindrical, the pressing surface structure can be a semi-circular arc surface structure.

[0042] In one embodiment of this application, the fastener 4 comprises two; During testing, the two fixing members 4 are respectively set at different ends of the tube body 5 to be tested.

[0043] It should be noted that by clamping different ends of the tube body 5 to be tested, the stability of the tube body 5 to be tested is increased, and the tube body 5 to be tested is further prevented from slipping during testing.

[0044] In one embodiment of this application, the friction surface is a detachable structure; the friction surface includes sandpaper 22; When the test is performed, the sandpaper 22 is attached to the outer wall of the tube body 5 to be tested.

[0045] It should be noted that the friction mechanism 2 is designed with a detachable structure, which allows for the replacement of sandpaper 22 of different specifications to simulate complex and ever-changing usage environments.

[0046] In the above embodiments of this application, the device has a simple structure, is easy to operate, has low manufacturing cost, high operating efficiency, and convenient power source acquisition. It is suitable for various scenarios and has good functional expansion and adaptability. At the same time, by controlling parameters such as pressure, trajectory, contact area and sliding frequency, the device can simulate different testing requirements for samples under different scenarios and environmental conditions, and is not limited to a single friction form.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
