Description

Technical Field

[0001] The present application relates to the technical field of bicycle inner tubes, and in particular to a bicycle inner tube tensile testing device. Background Art

[0002] Rubber products need to undergo a lot of mechanical property testing during the manufacturing process. Tensile strength is an important indicator in the production process of rubber products. The tensile strength of rubber refers to the ultimate ability of rubber products to resist tensile damage. In the production process of rubber inner tubes, a tensile strength testing device with good performance is required. Bicycle inner tube tensile test equipment is a device specially designed to evaluate the performance and durability of rubber inner tubes under stress conditions, meeting the testing requirements of different inner tubes, such as design according to standards and specifications.

[0003] For example, the utility model patent with publication number CN213580375U specifically discloses a rubber tensile testing machine used in rubber production. By providing a fixing component, it can not only firmly fix the rubber plastic strip and have a high measurement accuracy, but also protect the staff during the test to prevent the material from breaking and causing harm to people.

[0004] In the above patent, the device prevents the material from breaking by setting a fixing component. However, the device usually only fixes the outside of the rubber product. When it is used for a rubber inner tube, since the inside of the rubber sleeve inner tube is hollow, the fixing effect is not good when it is only fixed on the outside. The rubber sleeve may be deformed under the influence of external pressure, resulting in loose fixation, which may cause one end of the rubber inner tube to slip off the fixed clamping component during the tensile test. Especially when the inner tube is in a high tension state, the slipped inner tube may suddenly release energy, causing personal injury or equipment damage. Therefore, it is necessary to provide a bicycle inner tube tensile test device with good clamping performance to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a bicycle inner tube tensile testing device to achieve the effect of firmly clamping the inner tube during the tensile test.

[0008] Furthermore, two sets of rulers are arranged on both sides of the mounting frame.

[0010] Furthermore, a first bolt is threadedly connected to the center of the first clamping block, and an end of the first bolt away from the first clamping block is rotatably connected to the second clamping block.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] like Figure 1-Figure 2 As shown, the present application provides a bicycle inner tube tensile test equipment, including a base 1, which is arranged in a bicycle production factory. A test component 2 is arranged on the base 1, and the test component 2 is used to perform a tensile performance test on a rubber inner tube, so as to evaluate the tensile performance of the inner tube and make adjustments when necessary to ensure that its quality and performance meet expectations.

[0023] The test assembly 2 includes a mounting frame 21, a cylinder 22 is arranged on the top of the mounting frame 21, a tension sensor 23 is fixedly installed on the output end of the cylinder 22, and the tension sensor 23 is electrically connected to an external receiving device. At the same time, two groups of clamping assemblies 3 are arranged on the side of the tension sensor 23 away from the cylinder 22, and the clamping assemblies 3 are used to clamp one end of the rubber inner tube to be tested. At the same time, another group of clamping assemblies 3 is fixedly installed on the bottom of the mounting frame 21, and is used to clamp the other end of the rubber inner tube;

[0024] When the test starts, the two ends of the rubber inner tube are placed inside the two groups of clamping assemblies 3 respectively, and then the cylinder 22 is started to drive the two groups of clamping assemblies 3 to move away from each other, so that the inner tube is pulled and deformed, and the tension sensor 23 records the tension data in the test process in a timely and accurate manner, and transmits the information to the external receiving device to simulate the tensile force that the inner tube is subjected to in actual use, so as to evaluate its performance and durability;

[0025] At the same time, two sets of rulers 4 are arranged on both sides of the mounting frame 21, and the rulers 4 are used to measure the initial length of the rubber inner tube and the length change during the stretching process, thereby providing direct monitoring of the stretching degree of the inner tube and further enhancing the accuracy and controllability of the test.

[0026] like Figure 3-Figure 4 As shown, the clamping assembly 3 includes a fixed seat 31, a first clamping block 32 is arranged on one side of the top of the fixed seat 31, and a slide rail 35 is arranged on one side of the first clamping block 32, and a second clamping block 33 is slidably connected to the slide rail 35, and a first bolt 34 is threadedly connected to the center of the first clamping block 32, and the other end of the first bolt 34 is rotatably connected to the second clamping block 33. When the first bolt 34 is rotated, the second clamping block 33 is driven to move toward the direction of the first clamping block 32, so that the inner tube is clamped and fixed between the first clamping block 32 and the second clamping block 33, thereby ensuring the accuracy and repeatability of the test. At the same time, by adjusting the first bolt 34, the operator can easily control the clamping state of the inner tube.

[0027] In order to make the inner tube clamped more firmly during the test, improvements are made to the clamping assembly 3, specifically:

[0028] An accommodating assembly 5 is added to the first clamping block 32 and the second clamping block 33. The accommodating assembly 5 includes a first clamping block 51, which is fixedly mounted on the first clamping block 32. Meanwhile, a second clamping block 52 is arranged on the first clamping block 32. A second bolt 53 is arranged between the second clamping block 52 and the first clamping block 51. By adjusting the second bolt 53, the second clamping block 52 is moved closer to or away from the first clamping block 51.

[0029] At the same time, a accommodating cavity 54 is provided on the first clamping block 51 and the second clamping block 52. When the inner tube is tested, it will contact the inner wall of the accommodating cavity 54. At this time, the second clamping block 52 can be controlled to move toward the first clamping block 51, so that the inner tube is clamped up and down. Then, the first clamping block 32 can be controlled to move toward the second clamping block 33, so that the inner tube is clamped left and right, and then one side of the inner tube is completely wrapped and clamped, ensuring that the inner tube is fully supported and fixed during the clamping process to prevent the inner tube from falling off during the test.

[0030] In summary, the device, by providing the clamping component 3 and the containing component 5, can clamp the inner tube more firmly during the test process, thereby ensuring the accuracy and reliability of the test results; through the adjustment capability of the clamping component 3 and the design of the containing component 5, the inner tube is fully supported and fixed during the clamping process, thereby reducing the possibility of the inner tube detaching during the test process.

[0031] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
