Description

TECHNICAL FIELD

[0001] The present application relates to the field of tensile property testing equipment, in particular to a tensile side view instrument for silica gel products. BACKGROUND

[0002] Silica gel products are widely used in daily life, such as household supplies, medical devices, electronic components, etc., and their softness and durability are key performance indicators, so it is particularly important to test the mechanical properties of silica gel products reliably.

[0003] In the Chinese patent with publication number CN212483180U, a silica gel tensile tester is disclosed, which includes a rack, a bearing strip is fixed on the rack, a sliding strip is slidingly arranged on the rack, the bearing strip is parallel to the sliding strip, a plurality of clamping assemblies for clamping silica gel products are arranged between the bearing strip and the sliding strip, a distance adjusting assembly is arranged on the rack for adjusting the distance between the sliding strip and the bearing strip, a scale line is arranged on one side of the rack, and the length direction of the scale line is consistent with the movement direction of the sliding strip.

[0004] Although this device can simultaneously test the tensile strength of multiple silica gel products, it is still not very stable to fix the silica gel products with only clamps. During the test, the silica gel products may move or fall out of the clamps, resulting in inaccurate test data. CONTENT OF THE UTILITY MODEL

[0005] In order to prevent the silica gel products from slipping or falling off, the present application provides a tensile tester for silica gel products.

[0006] The tensile tester for silica gel products provided by the present application adopts the following technical solution:

[0007] A tensile tester for silica gel products, comprising a base plate, a support seat is fixedly connected to the upper surface of the base plate, a sliding table is fixed to the upper side of the support seat, a sliding block is slidingly connected to the top of the sliding table, a fixed seat is fixedly connected to the upper surface of the base plate, the sliding table passes through the fixed seat, a tensile meter is fixedly connected to the top end of the fixed seat, a fixing mechanism for fixing silica gel is arranged on the side of the tensile meter and the sliding block, and the fixing mechanism comprises a fixing bracket and a fixing rod arranged above the fixing bracket for passing through the silica gel product.

[0008] By adopting the above technical solution, the performance parameters of the silica gel product under tension can be accurately measured, the silica gel product is fixed between the tensile meter and the sliding block by the fixing mechanism, the sliding block moves along the sliding table, and linear stretching of the silica gel product is realized. The silica gel product is stretched by the sliding block until it breaks, at which point the numbers on the tensile meter can be read to obtain the test results.

[0009] Optionally, the fixing bracket is U-shaped, with the U-shaped openings of the two fixing brackets located on opposite sides, and the opposite ends of the two fixing brackets forming an abutment portion, which is bent toward the opposite side.

[0010] By adopting the above technical solution, the fixing rod can be stably fixed in the fixing bracket during the tensile process, ensuring that the silicone product is stably fixed between the two fixing brackets, so that the silicone product is not easy to fall out of the fixing bracket during the subsequent tensile test, thus ensuring the stability of the test process.

[0011] Optionally, one end of the fixing rod is a puncture end and the other end is a gripping end, and the puncture end is a pointed tip.

[0012] By adopting the above technical solution, the puncture end is set as a pointed tip to facilitate the insertion of the fixing rod into the silicone product, making the puncture process more labor-saving, thereby ensuring that the silicone product is stably fixed on the fixing rod, saving time and effort in fixing the sample, and improving testing efficiency.

[0013] Optionally, the slide table is provided with a synchronous gear and a synchronous belt that meshes with the synchronous gear. The slider is fixedly connected to the synchronous belt, and a driving component for driving the synchronous gear to rotate is provided at one end of the slide table.

[0014] By adopting the above technical solution, the synchronous gear and synchronous belt transmit power through meshing, preventing relative slippage between them and achieving accurate synchronous transmission. This ensures transmission precision and allows the slider to slide stably, guaranteeing the stability of the testing process. Furthermore, the synchronous belt and synchronous gear do not require lubrication during transmission, effectively simplifying maintenance and reducing maintenance costs and workload.

[0015] Optionally, the driving component is a geared motor.

[0016] By adopting the above technical solution, the geared motor can effectively improve the torque. In the tensile testing environment, the geared motor can ensure the stable movement of the slider during the test, thereby ensuring the stability of the test.

[0017] Optionally, the top of the slide table is provided with a guide rail, and the slider is provided with a guide groove for the guide rail to pass through.

[0018] By adopting the above technical solution, during the stretching process, the guide rail will abut against the inner wall of the guide groove, thereby ensuring that the slider will not wobble during movement, ensuring that the stretching process is linear, and making the test results more accurate.

[0019] Optionally, the top of the slider is provided with a waist-shaped hole for mounting a fixing bracket, and the waist-shaped hole is arranged vertically.

[0020] By adopting the above technical solution, the fixed bracket on the slider can be adjusted according to the height of the tension gauge, thereby ensuring that the fixed brackets on both sides are on the same horizontal plane and ensuring the accuracy of the test data during the tensile process.

[0021] Optionally, grooves are provided on both sides of the slide.

[0022] By adopting the above technical solution, when the material fractures during the tensile test, the slide will bear a large instantaneous load. The grooves on both sides can increase the structural strength, making the slide less prone to deformation, thereby ensuring the normal operation of the slide.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. By setting up fixing rods and fixing brackets, the silicone products can be effectively fixed, and they are not prone to slippage or falling off the fixing rods during the stretching process, thus ensuring the stability of the tensile test process.

[0025] 2. By setting up a speed reduction motor, synchronous gears and synchronous belts, the slider can move stably and uniformly during the tensile test, thereby ensuring the stability of the test process. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a tensile testing instrument for silicone products. (Refer to...) Figure 1The tensile tester for silicone products includes a base plate 1. A support base 11 and a fixed base 12 are fixedly connected to the upper surface of the base plate 1. A slide table 2 is fixedly connected to the upper side of the support base 11. A slider 3 is slidably connected to the top of the slide table 2. A tension gauge 4 is fixedly connected to the top of the fixed base 12. Both the tension gauge 4 and the slider 3 are connected to a fixing mechanism 5 for fixing the silicone. During the tensile test, the silicone is fixed to the fixing mechanisms 5 on both sides. The movement of the slider 3 stretches the silicone. At this time, the tension gauge 4 will display a value, and the tensile strength of the silicone can be inferred from the value.

[0033] Reference Figure 2 The fixing mechanism 5 includes a fixing bracket 51 fixedly connected to the tension gauge 4 or the slider 3, and a fixing rod 52 disposed above the fixing bracket 51 for passing through the silicone product. The fixing bracket 51 is U-shaped, with the U-shaped openings of the two fixing brackets 51 facing each other. The opposing ends of the two fixing brackets 51 are abutment portions 511, which are bent towards opposite sides. The bending of the two abutment portions 511 towards opposite sides creates space for the fixing rod 52 to be placed and abutted, making it less likely for the fixing rod 52 to detach from the fixing bracket 51 during the tensile process, thus ensuring the stability of the tensile test. In this embodiment, the abutment portion 511 bends upward, so that the fixing rod 52 is disposed above the bracket; in other embodiments, the abutment portion 511 can also bend downward, so that the fixing rod 52 is disposed below the bracket. Comparatively, being disposed above the bracket makes it easier for workers to place the fixing rod 52 and the silicone product on the fixing bracket 51, making the fixing process more convenient.

[0034] Reference Figure 2 One end of the fixing rod 52 is a puncture end 521, and the other end is a holding end 522. The puncture end 521 is set with a pointed tip. The pointed tip makes it easier to insert the fixing rod 52 into the silicone product and makes the puncture process less strenuous, ensuring that the silicone product is stably fixed on the fixing rod 52, thereby saving time and effort in fixing the sample.

[0035] Reference Figure 1 , Figure 3 The slide table 2 has synchronous gears 21 at both ends, which mesh with a synchronous belt 22. The slider 3 is fixedly connected to the synchronous belt 22. The meshing transmission between the synchronous gears 21 and the synchronous belt 22 prevents relative slippage between them, thus ensuring transmission accuracy and allowing the slider 3 to slide stably. One end of the slide table 2 has a drive component 23 for driving the synchronous gears 21 to rotate; this drive component 23 is a geared motor. Compared to ordinary motors, geared motors have greater torque. Under tensile testing conditions, geared motors can ensure the stable movement of the slider 3 during the test, ensuring test stability.

[0036] Reference Figure 4To ensure that the slider 3 does not wobble during movement, guide rails 24 are symmetrically arranged on both sides of the top of the slide table 2, and guide grooves 31 are correspondingly provided on the bottom of the slider 3 for sliding connection of the guide rails 24. During the stretching process, the guide rails 24 will abut against the inner wall of the guide grooves 31, thereby reducing the wobble of the slider 3 during movement, ensuring that the stretching process is linear, and making the test results more accurate.

[0037] Reference Figure 4 The top of the slider 3 has a waist-shaped hole 32 for mounting the fixed bracket 51, and the waist-shaped hole 32 is vertically arranged. The fixed bracket 51 on the slider 3 can move up and down along the waist-shaped hole 32 to adjust the height, so that the fixed bracket 51 on the slider 3 can be adjusted according to the height of the tension gauge 4, ensuring that the fixed brackets 51 on both sides are on the same plane, thereby ensuring linear tension and ensuring the accuracy of the test results.

[0038] Reference Figure 4 The slide table 2 has grooves 25 on both sides. The grooves 25 reduce material costs and weight. Simultaneously, the grooves 25 optimize the structure and increase structural strength. During testing, the material needs to be stretched to fracture to measure its performance. When the material fractures, the slide table 2 will bear a large instantaneous load. The grooves 25 on both sides enhance the structural strength and rigidity of the slide table 2, making it less prone to deformation and improving durability.

[0039] The implementation principle of a tensile tester for silicone products in this application embodiment is as follows: the fixing rods 52 on both sides are inserted into the silicone product and then placed on the fixing bracket 51. The reduction motor is started, and the synchronous gear 21 rotates to drive the synchronous belt 22 to move, so that the slider 3 can move on the slide table 2. The silicone product is stretched until it breaks. At this time, the corresponding value can be read from the tensile gauge 4. The tensile performance of the silicone can be inferred from the value.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
