Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a leather flexural strength testing device. Background Technology

[0002] The leather flexure test assesses the durability and flexibility of leather products by simulating repeated bending and folding during actual use. It involves setting specific flexing angles, frequencies, and loads, subjecting the leather sample to cyclic flexing at specified angles, speeds, and cycles. The leather flexure test has wide applications in the leather industry. It can be used to test the flexure resistance of shoe uppers, linings, clothing materials, and bag materials, as well as to evaluate the durability and flexibility of leather products such as shoes, bags, and belts. Through this test, the performance of leather materials under repeated bending and folding can be understood, thereby optimizing production processes and improving product quality.

[0003] Current leather flexural testing equipment is structurally complex and cumbersome to install and disassemble leather pieces. It also makes it difficult to quickly fix and disassemble the pieces. Furthermore, due to the randomness of single experimental data, multiple sets of experiments are often required when conducting flexural tests on leather. However, current leather flexural testing equipment is unable to conduct flexural tests on multiple pieces of leather simultaneously.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a leather flexural strength testing device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a leather flexural strength testing device, comprising a connecting base plate, support plates symmetrically fixedly installed at the upper end of the outer wall of the connecting base plate, a fixed rod fixedly connected between the two support plates, a fixed plate linearly fixedly installed on the lower side of the outer wall of the fixed rod, a reciprocating rotating plate rotatably installed at the lower end of the outer wall of the fixed plate, an opening one on the fixed plate, and an opening two on the rotating plate.

[0007] As a further technical solution of this utility model, the fixing plate and the rotating plate are detachably connected to leather blocks that pass through the first opening and the second opening. The upper left side of the outer wall of the fixing plate is linearly connected to a hook one, and the lower left side of the outer wall of the rotating plate is linearly connected to a hook two. The upper and lower sides of the side wall of the leather block are provided with mounting holes arranged linearly, and the mounting holes on the upper and lower sides are respectively inserted into the hook one and the hook two.

[0008] As a further technical solution of this utility model, a rotating rod is rotatably connected between the two support plates and below the fixed rod. Cam blocks are linearly arranged and fixedly installed on the side wall of the rotating rod, and the cam blocks are slidably connected to the lower side of the outer wall of the rotating plate.

[0009] As a further technical solution of this utility model, a motor frame is fixedly installed on the upper end of the outer wall of the connecting base plate, and a motor is fixedly connected to the upper end of the outer wall of the motor frame. The output end of the motor rotates through the support plate and is fixedly connected to the rotating rod.

[0010] As a further technical solution of this utility model, a support frame is linearly arranged and fixedly installed on the upper end of the outer wall of the connecting base plate, and an installation plate is fixedly connected to the upper end of the outer wall of each support frame. A connecting plate is integrally formed at both the front and rear ends of each rotating plate, and a return spring is fixedly installed between the installation plate and the connecting plate.

[0011] This invention provides a leather flexural strength testing device, which has the following advantages compared with the prior art:

[0012] 1. This utility model uses a starting motor to drive a rotating rod to rotate, which in turn drives all the cam blocks to rotate. The rotating cam blocks press against the bottom of the rotating plate, causing the rotating plate to rotate around the bottom of the fixed plate. At the same time, the device uses a return spring to press the rotating plate, causing it to rotate downwards and reset after reaching its maximum angle. This reciprocating motion of the fixed plate achieves the reciprocating oscillation of the fixed plate. Thus, the device uses the reciprocating oscillation of the rotating plate below the fixed plate to drive the leather block fixed on the fixed plate and the rotating plate to reciprocate and bend, thus performing a flexural resistance test on it.

[0013] 2. When in use, the device can quickly install and fix the leather block by inserting hook one and hook two into the mounting holes on the upper and lower sides of the leather block, and facilitate subsequent disassembly. At the same time, by setting multiple sets of fixing plates, rotating plates and cam blocks, the device can conduct flexural resistance tests on multiple leather blocks at one time, thereby improving the convenience of the device when in use.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model provides a technical solution for a leather flexural resistance testing device: it includes a connecting base plate 100, and support plates 110 are symmetrically fixedly installed on the upper end of the outer wall of the connecting base plate 100. A fixing rod 200 is fixedly connected between the two support plates 110. A fixing plate 300 is linearly arranged and fixedly installed on the lower side of the outer wall of the fixing rod 200. A reciprocating rotating plate 400 is rotatably installed on the lower end of the outer wall of the fixing plate 300. An opening 310 is opened on the fixing plate 300, and an opening 410 is opened on the rotating plate 400. The device drives the leather block 500 fixed on the fixing plate 300 and the rotating plate 400 to reciprocate and bend through the reciprocating swing of the rotating plate 400 below the fixing plate 300, and performs a flexural resistance test on it. A rotating rod 600 is rotatably connected between two support plates 110 and below the fixed rod 200. Cam blocks 610 are linearly arranged and fixedly installed on the side wall of the rotating rod 600. The cam blocks 610 are slidably connected to the lower side of the outer wall of the rotating plate 400. A motor frame 620 is fixedly installed on the upper end of the outer wall of the connecting base plate 100. A motor 630 is fixedly connected to the upper end of the outer wall of the motor frame 620. The output end of the motor 630 rotates through the support plate 110 and is fixedly connected to the rotating rod 600. The device drives the rotating rod 600 to rotate by starting the motor 630, thereby driving all the cam blocks 610 to rotate. The rotating cam blocks 610 press against the lower part of the rotating plate 400, causing the rotating plate 400 to rotate around the lower end of the fixed plate 300. Support frames 700 are linearly arranged and fixedly installed on the upper part of the outer wall of the connecting base plate 100. Each support frame 700 is fixedly connected to the upper part of the outer wall of the mounting plate 710. Each rotating plate 400 has a connecting plate 720 integrally formed at both the front and rear ends. A return spring 730 is fixedly installed between the mounting plate 710 and the connecting plate 720. The return spring 730 squeezes the rotating plate 400, causing the rotating plate 400 to rotate downwards and reset after rotating to the maximum angle. This process is repeated to realize the reciprocating swing of the fixed plate 300.

[0022] like Figure 1-5 As shown, leather blocks 500 are detachably connected to both the fixed plate 300 and the rotating plate 400, with through opening 310 and opening 410 respectively. Hook 1 510 is linearly and fixedly connected to the upper left side of the outer wall of the fixed plate 300, and hook 2 520 is linearly and fixedly connected to the lower left side of the outer wall of the rotating plate 400. Mounting holes 530 are linearly arranged on the upper and lower sides of the side wall of the leather block 500. The mounting holes 530 on the upper and lower sides are respectively inserted into hook 1 510 and hook 2 520. By hanging the upper and lower sides of the leather block 500 onto hook 1 510 and hook 2 520 respectively, the device can quickly install and fix the leather block 500, and facilitate subsequent disassembly.

[0023] The working principle of this utility model is as follows: In use, the device firstly connects to the mounting holes 530 on the upper and lower sides of the leather block 500 via hook 1 510 and hook 2 520, respectively, enabling quick installation and fixation of the leather block 500, while facilitating subsequent disassembly. The device then drives the rotating rod 600 to rotate via the starting motor 630, thereby causing all the cam blocks 610 to rotate. The rotating cam blocks 610 press against the lower part of the rotating plate 400, causing the rotating plate 400 to rotate around the lower end of the fixed plate 300. The device compresses the rotating plate 400 with a return spring 730, causing the rotating plate 400 to rotate downwards and reset after reaching its maximum angle. This reciprocating motion achieves the reciprocating swing of the fixed plate 300. The reciprocating swing of the rotating plate 400 below the fixed plate 300 causes the leather block 500 fixed on the fixed plate 300 and the rotating plate 400 to reciprocate and bend, thus conducting a flexural resistance test. At the same time, by setting up multiple sets of fixed plates, rotating plates and cam blocks, the device can conduct flexural resistance tests on multiple leather blocks at the same time.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
