Description

Technical Field

[0001] This utility model belongs to the field of rubber tube parameter testing technology, and more specifically, it relates to a tensile testing device for rubber tubes. Background Technology

[0002] Tensile testing of rubber hoses serves several important purposes: firstly, it assesses the mechanical properties, material reliability, and suitability of the rubber hose; secondly, it determines the maximum stress the rubber hose can withstand during tension; thirdly, it evaluates the maximum elongation of the material before fracture; fourthly, it reveals the elastic recovery capacity of the rubber hose; and fifthly, it uses tensile testing to check the performance stability of different batches of rubber hoses, ensuring product quality consistency. Furthermore, given that many industries (such as automotive, medical, and industrial equipment) have strict standards and specifications for the mechanical properties of rubber hoses (such as ISO and ASTM standards), tensile testing is a necessary step in verifying whether rubber hoses meet the corresponding standards.

[0003] However, at present, most of the tensile testing devices for rubber hoses on the market have certain limitations and cannot simultaneously conduct experiments on the tensile amount and stress of the rubber hose, which to some extent affects the comprehensiveness and accuracy of the performance testing of rubber hoses. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tensile testing device for rubber tubes, which solves the problem that most existing experimental devices for tensile testing of rubber tubes cannot simultaneously test the tensile amount and stress of rubber tubes.

[0005] This utility model discloses a tensile testing device for rubber tubes, achieved through the following specific technical means:

[0006] A tensile testing device for rubber tubes includes: a top plate; a shaft is provided on the lower side of the top plate, and a fixing member is sleeved around the shaft; four sets of angled frames are arranged below the top plate; a bottom plate is installed below the angled frames; an electric telescopic rod is provided above the bottom plate; another shaft is connected above the electric telescopic rod, and a fixing member is also sleeved around the shaft; a measuring spring is provided between the two sets of fixing members; a display is equipped on the measuring spring; the display has a screen and control buttons.

[0007] Furthermore, top slots are provided at the four corners of the lower side of the top plate of the device, and the upper end of the folded frame is embedded in the top slot. Bottom slots are provided at the four corners of the upper side of the bottom plate of the device, and the lower end of the folded frame is embedded in the bottom slot. The front sides of the two sets of folded frames on the front side are marked with scale lines.

[0008] Furthermore, a positioning plate is provided at the upper end of the shaft on the upper side, and a protrusion is provided on the surface of the shaft below the positioning plate. A positioning groove is provided at the upper part of the inside of the fixing component, and a groove is provided on the inner wall of the fixing component below the positioning groove. The positioning plate is fitted into the positioning groove. Fixing bolts are installed on both sides of the fixing component, and fixing nuts are provided on the rear side of the fixing bolts.

[0009] Furthermore, a positioning plate is provided at the lower end of the lower shaft, and a protrusion is provided on the surface of the shaft above the positioning plate. A positioning groove is provided at the lower part of the inside of the fixing member, and a groove is provided on the inner wall of the fixing member above the positioning groove. The positioning plate is embedded in the positioning groove. Fixing bolts are provided on both sides of the fixing member, and fixing nuts are installed on the rear side of the fixing bolts.

[0010] Furthermore, fastening rings are installed on both sides below the top plate of the device and on both sides above the bottom plate of the device. A fastening spring is connected between the two sets of fastening rings on the same side. Fastening hooks are provided at both the upper and lower ends of the fastening springs and are hooked onto the fastening rings.

[0011] Furthermore, measuring rings are installed on both the front and rear sides of the inner end of the fixing member, and measuring springs are connected between the measuring rings on the same side. Both ends of the measuring springs are equipped with measuring hooks, which are hooked onto the measuring rings.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, by setting up a scale and a display, allows for real-time observation of the rubber tube's stretching amount, intuitively presenting the degree of deformation during the stretching process. The display clearly shows the specific force value experienced by the rubber tube when it is under stretching, providing accurate data support for understanding the stress situation of the rubber tube. Through the combination of these two, not only can the stretching amount and stress level of the rubber tube be detected simultaneously, but the data from these two aspects can also be comprehensively evaluated. This is highly beneficial for conducting a comprehensive and in-depth analysis and evaluation of various parameters of the rubber tube from multiple dimensions, thereby more accurately grasping the key characteristics such as the mechanical properties of the rubber tube, and providing a reliable basis for quality control, application adaptation, and many other aspects of the rubber tube.

[0014] 2. This utility model, by setting protrusions and grooves, allows the rubber tube to be fitted onto the shaft during relevant operations. At this time, the inner wall of the rubber tube contacts the protrusions on the shaft, while its outer wall contacts the grooves on the fixing component. It is worth noting that the protrusions on the shaft and the grooves on the fixing component are staggered. This unique distribution effectively increases the friction between the shaft and the fixing component and the rubber tube. During the tensile test of the rubber tube, sufficient friction plays a crucial role. It helps to stabilize the position of the rubber tube and effectively prevents the rubber tube from falling off, thereby ensuring that the tensile test can be carried out smoothly and stably.

[0015] 3. By incorporating a fastening spring, this utility model provides excellent flexibility and adaptability. In practical applications, given the different sizes and specifications of rubber tubes, when tensile testing is required on rubber tubes of a specific size and specification, the top and bottom plates of the device can be disassembled, and a suitable shaft and fixing components of appropriate size and specification can be replaced. Through this operation method, the device can meet the needs of tensile testing of rubber tubes of different sizes and specifications, greatly expanding the applicability of the device, enhancing its value, and ensuring that it can effectively play its role and smoothly carry out the corresponding tensile testing work when faced with diverse rubber tube testing tasks.
