Description

Technical Field

[0001] This utility model belongs to the field of tensile testing technology, and specifically relates to a tooling for testing the tensile strength of sealant. Background Technology

[0002] Sealant is a sealing material that deforms to conform to the shape of the sealing surface, does not flow easily, and has a certain degree of adhesion. It is made from dry or non-dry viscous substances such as asphalt, natural or synthetic resins, and natural or synthetic rubber as base materials, combined with inert fillers such as talc, kaolin, carbon black, titanium dioxide, and asbestos, and then plasticizers, solvents, curing agents, accelerators, etc. The main function of sealant is to seal and fill gaps in structural components, and it has functions such as preventing leakage, waterproofing, vibration damping, sound insulation, and heat insulation. It is widely used in the sealing of buildings, transportation, electronic instruments and meters, and components.

[0003] Currently, after the sealing strip is produced, the tensile strength of the sealant needs to be tested. However, during the tensile strength test, if the sealant cannot withstand the tensile force and breaks, the resulting ejection force will cause a strong impact on the enclosure. This strong impact will cause deformation of the protective enclosure and generate abnormal noise. Furthermore, the broken sealant will fall randomly and become scattered throughout the enclosure, requiring manual removal of the sealant waste. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for testing the tensile strength of sealant, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealant tensile testing fixture, comprising a tensile testing shell, a closed cover plate at the upper end of the tensile testing shell, an inclined guide shell fixed at the lower end of the tensile testing shell, and a discharge port communicating with the tensile testing shell at the lower end of the inclined guide shell. Through the tensile testing shell and the inclined guide shell, after the clamp assembly is unlocked, the sealant strip automatically slides down the inclined guide shell under gravity to the discharge port and is discharged. This eliminates the tedious step of manually removing material from the tensile testing shell after tensile testing.

[0006] The tensile testing shell is equipped with a clamping assembly inside, and a buffer pad is embedded and fixed on the inner wall of the tensile testing shell. With the tensile testing shell, the closing cover plate and the buffer pad, when the sealing strip is broken, the elastic force generated by the breakage of the sealing strip will hit the buffer pad, thereby buffering the impact force and reducing the impact noise.

[0007] It should be noted in the solution that a flip hinge is provided between the closed cover plate and the tensile testing shell, and a support base is fixed at the rear of the tensile testing shell.

[0008] It is further worth noting that the clamp assembly includes an adjusting slide, a movable clamping plate, and a fixed clamping plate. The adjusting slide is disposed in the inner cavity of the tensile testing shell, the movable clamping plate is slidably connected to one side surface of the adjusting slide, and the fixed clamping plate is fixed to one side surface of the adjusting slide.

[0009] Furthermore, it should be noted that a lifting slider is slidably connected in the groove of the adjusting slide block, and one end of the lifting slider extending out of the adjusting slide block is fixed to one side surface of the movable clamping plate.

[0010] In a preferred embodiment, the adjusting slide is internally rotatably connected to an adjusting screw, and an adjusting knob is fixed to one end of the adjusting screw that extends out of the adjusting slide. The adjusting screw is threadedly connected to the lifting slider, and anti-slip pads are fixed to the opposite surfaces of the movable clamping plate and the fixed clamping plate.

[0011] In a preferred embodiment, a sealing frame is fixed to the lower end face of the closed cover, and a drive cylinder is fixed to both ends of the tensile testing shell, with the output end of the drive cylinder fixed to the adjusting slide.

[0012] Compared with the prior art, the sealant tensile strength testing fixture provided by this utility model has at least the following beneficial effects:

[0013] By using a tension detection shell, a closed cover, and a buffer pad, when the sealing strip is broken, the ejection force generated by the breakage of the sealing strip will impact the buffer pad, thereby buffering the impact force and reducing impact noise.

[0014] With the addition of a tensile testing shell and an inclined guide shell, after the clamping assembly is unlocked, the sealing strip automatically slides down the inclined guide shell under gravity to the discharge port, thus eliminating the tedious step of manually removing material from the tensile testing shell after the tensile test.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Please see Figure 1-4 This utility model provides a sealant tensile testing fixture, including a tensile testing shell 1, a closed cover plate 3 at the upper end of the tensile testing shell 1, an inclined guide shell 2 fixed at the lower end of the tensile testing shell 1, a discharge port 16 connected to the tensile testing shell 1 at the lower end of the inclined guide shell 2, a clamping assembly 6 inside the tensile testing shell 1, and a buffer pad 14 embedded and fixed on the inner wall of the tensile testing shell 1.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a hinge 4 is provided between the closed cover plate 3 and the tensile testing shell 1, and a support base 17 is fixed at the rear of the tensile testing shell 1.

[0023] Further as Figure 3 As shown, it is worth noting that the clamp assembly 6 includes an adjusting slide 7, a movable clamp 8, and a fixed clamp 9. The adjusting slide 7 is disposed in the inner cavity of the tensile testing housing 1. The movable clamp 8 is slidably connected to one side surface of the adjusting slide 7, and the fixed clamp 9 is fixed to one side surface of the adjusting slide 7.

[0024] The solution has the following working process: Before use, the closed cover plate 3 is lifted from the tensile testing shell 1, and then the two ends of the sealing strip are clamped and fixed on the two clamping components 6. Then, the drive cylinder 5 is turned on. The drive cylinder 5 controls the two clamping components 6 to move away from each other and stretch the sealing strip to complete the tensile test. When the sealing strip is broken, the elastic force generated by the breakage of the sealing strip will hit the buffer pad 14 to buffer the impact force and reduce the impact noise.

[0025] As can be seen from the above working process, when the sealing strip is broken, the elastic force generated by the breakage of the sealing strip will hit the buffer pad 14 to buffer the impact force and reduce the impact noise.

[0026] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a lifting slider 10 is slidably connected in the groove of the adjusting slide block 7, and one end of the lifting slider 10 extending out of the adjusting slide block 7 is fixed to one side surface of the movable clamping plate 8.

[0027] Further as Figure 4 As shown, it is worth noting that the internal rotating connection of the adjusting slide 7 is an adjusting screw 11. One end of the adjusting screw 11 extending out of the adjusting slide 7 is fixed with an adjusting knob 12. The adjusting screw 11 is threadedly connected to the lifting slider 10. Anti-slip pads 13 are fixed on the opposite side surfaces of the movable clamping plate 8 and the fixed clamping plate 9. After the clamping assembly 6 is unlocked, the sealing strip automatically slides down the inclined guide shell 2 under the action of gravity to the discharge port. This can save the tedious step of manually removing material from the tensile testing shell 1 after the tensile test.

[0028] Further as Figure 1 As shown, it is worth noting that a sealing frame 15 is fixed to the lower end of the closed cover plate 3, and a drive cylinder 5 is fixed to both ends of the tensile testing shell 1. The output end of the drive cylinder 5 is fixed to the adjusting slide 7.

[0029] In summary: when the sealing strip is broken, the ejection force generated by the breakage will impact the buffer pad 14, thereby buffering the impact force and reducing impact noise; after the clamp assembly 6 is unlocked, the sealing strip will automatically slide down the inclined guide shell 2 under gravity to the discharge port, thus eliminating the tedious step of manually removing material from the tensile testing shell 1 after the tensile test.
