[0002] A pull-out force tester is a device used to measure the mechanical properties of materials under tensile conditions. It is widely used in industries such as plastics, metals, rubber, and textiles to evaluate the tensile strength, elongation, and fracture characteristics of materials.

[0003] A pull-out force tester typically consists of a frame, a servo motor, a transmission device, a fixture, and a sensor. The transmission device moves one of the fixtures, increasing the distance between the two fixture assemblies, which allows the product to be stretched. The pull-out test is then performed by measuring the tensile force reading from the sensor.

[0004] When installing and using the fixtures and sensors, they are fixed to the output end of the transmission device using fasteners and bolts. When inspecting and maintaining the fixtures and sensors, wrenches are needed to disassemble them, which is inconvenient for manual disassembly and maintenance, thus presenting certain defects.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] This utility model provides, for example Figure 1-4The pull-out force tester shown includes a support platform 1, a first clamp 2 mounted on the top of the support platform 1, a mounting bracket 3 mounted on the top of the support platform 1, a mounting plate 4 disposed inside the mounting bracket 3, and a drive assembly disposed on the mounting bracket 3. The drive assembly is used to drive the mounting plate 4 to move up and down inside the mounting bracket 3. The drive assembly consists of two screws, two drive blocks, a drive motor, gears, and a chain. The drive motor drives the two screws to rotate synchronously through the gears and chain. The two screws drive the two ends of the mounting plate 4 to move up and down synchronously through the two drive blocks. A fixing plate 5 is fixedly connected to the support platform 1. At the bottom of mounting plate 4, the second clamp 6 is set at the bottom of the fixed plate 5, the tension sensor 7 is set between the second clamp 6 and the fixed plate 5, and the connecting component 8 is set at the end of the tension sensor 7. The connecting components 8 at the end of the tension sensor 7 are symmetrically arranged, so that under the action of the two connecting components 8, the tension sensor 7 and the second clamp 6 can be stably installed at the bottom of the fixed plate 5. When the first clamp 2 and the second clamp 6 clamp the product, the drive component drives the mounting plate 4 to rise, and the second clamp 6 moves away from the first clamp 2. The product pull test can be performed by reading the tension sensor 7.

[0042] Furthermore, the connecting assembly 8 includes a fixed sleeve 81 and a connecting post 82. The two fixed sleeves 81 are respectively fixedly installed on the opposite side of the second clamp 6 and the fixed plate 5. The two connecting posts 82 are respectively fixedly connected to both ends of the tension sensor 7. One end of the outer wall of the connecting post 82 is slidably engaged with the fixed sleeve 81. That is, the connecting post 82 is engaged with the fixed sleeve 81, so that the tension sensor 7 can be installed between the fixed plate 5 and the second clamp 6.

[0043] In particular, the connecting assembly 8 also includes a fixing collar 83 and a locking block 84. The fixing collar 83 is fixedly sleeved on one end of the inner cavity of the fixing sleeve 81, and the locking block 84 is fixedly connected to the outside of the connecting post 82. The locking block 84 is engaged with the side of the fixing collar 83 facing the inside of the fixing sleeve 81. That is, the locking block 84 is engaged inside the fixing sleeve 81, which can ensure the stability of the engagement between the connecting post 82 and the fixing sleeve 81.

[0044] Furthermore, the connecting assembly 8 also includes a positioning rod 85 and a slot 86. The positioning rod 85 is fixedly connected to the side of the fixing collar 83 facing the inside of the fixing sleeve 81. The outer wall of the positioning rod 85 is slidably inserted into the locking block 84. The positioning rod 85 can improve the stability of the locking block 84 inside the fixing sleeve 81. The slot 86 is opened on the inner wall of the fixing collar 83 and matches the locking block 84. The connecting assembly 8 also includes a limiting spring 87 and a disc. The limiting spring 87 is sleeved inside the fixing sleeve 81 and is used to provide an elastic limiting force to the connecting post 82. The disc is sleeved inside the fixing sleeve 81 and is located at the limiting position. Between the spring 87 and the connecting post 82, the limiting spring 87 can provide elastic force for the connecting post 82 to move outward from the fixed sleeve 81. Under the gravity of the second clamp 6 and the tension sensor 7, it can improve the stability of the positioning rod 85 and the locking block 84. The connecting post 82 has an extended protruding part, which can squeeze the connecting post 82 into the fixed sleeve 81, so that the connecting post 82 can drive the locking block 84 to separate from the positioning rod 85. Then, the connecting post 82 can be rotated relative to the fixed sleeve 81 so that the locking block 84 corresponds to the slot 86 on the fixed collar 83, so that the connecting post 82 can be disassembled, thereby disassembling the second clamp 6 and the tension sensor 7.

[0045] In particular, the bottom of the mounting plate 4 is provided with an anti-drop component 9, which includes a connecting plate 91, a bearing block 92, and a fixing block 93. The connecting plate 91 is fixedly connected to the bottom of the mounting plate 4, the bearing block 92 is fixedly connected to the bottom of the connecting plate 91 facing the second clamp 6, and the fixing block 93 is fixedly installed on the side of the second clamp 6. The fixing block 93 is located on top of the bearing block 92, and there is a certain distance between the bottom of the fixing block 93 and the bearing block 92, so as not to affect the use of the tension sensor 7. The connecting plate 91, the bearing block 92, and the fixing block 93 can reduce the possibility of the second clamp 6 breaking and falling at the top connection, thereby improving the safety of the second clamp 6.

The drive assembly is used to drive the mounting plate 4 to move up and down inside the mounting bracket 3. The drive assembly consists of two screws, two drive blocks, a drive motor, gears, and a chain. The drive motor drives the two screws to rotate synchronously through the gears and chain. The two screws drive the two ends of the mounting plate 4 to move up and down synchronously through the two drive blocks. A fixing plate 5 is fixedly connected to the support platform 1. At the bottom of mounting plate 4, the second clamp 6 is set at the bottom of the fixed plate 5, the tension sensor 7 is set between the second clamp 6 and the fixed plate 5, and the connecting component 8 is set at the end of the tension sensor 7. The connecting components 8 at the end of the tension sensor 7 are symmetrically arranged, so that under the action of the two connecting components 8, the tension sensor 7 and the second clamp 6 can be stably installed at the bottom of the fixed plate 5. When the first clamp 2 and the second clamp 6 clamp the product, the drive component drives the mounting plate 4 to rise, and the second clamp 6 moves away from the first clamp 2. The product pull test can be performed by reading the tension sensor 7.

[0048] In particular, the bottom of the mounting plate 4 is provided with an anti-drop component 9, which includes a connecting plate 91, a bearing block 92, and a fixing block 93. The connecting plate 91 is fixedly connected to the bottom of the mounting plate 4, the bearing block 92 is fixedly connected to the bottom of the connecting plate 91 facing the second clamp 6, and the fixing block 93 is fixedly installed on the side of the second clamp 6.

The connecting plate 91, the bearing block 92, and the fixing block 93 can reduce the possibility of the second clamp 6 breaking and falling at the top connection, thereby improving the safety of the second clamp 6.
