Description

Technical Field

[0001] This utility model relates to the technical field of foamed silicone sponge products, specifically a high-strength foamed silicone sponge product. Background Technology

[0002] Sponge silicone foam tubes are products made through the extrusion process of foamed silicone. Compared to non-foamed silicone, they are softer, more suitable for cushioning and sealing, and can be made thicker for use as insulation tubes. Sponge silicone foam tubes do not have regular cross-sectional shapes; they are developed and produced according to customer drawings, samples, or accessories. Colors are mainly white, brownish-red, black, gray, and blue; hardness ranges from 10 to 45 Shore C; dimensions are within ∮80mm; density ranges from 0.3g / cm³ to 0.65g / cm³. By introducing foreign foaming technology, the foam density is uniform, ranging from 0.5 to 0.85, resulting in a soft, lightweight product with good resilience, strong tensile strength, and advantages such as being odorless, non-toxic, and tasteless. These products are often used in high-requirement mechanical equipment or electronic instruments for shock absorption, sealing, insulation, and high-temperature resistance. Directly molded silicone sponge foam sealing rings are formed independently in a mold, fermented under high temperature and pressure, and can be processed into silicone foam components with relatively simple surfaces.

[0003] Sponge silicone foam tubes are a type of soft material, but the required hardness varies depending on the application scenario. In existing processes, increasing the strength requires an overall increase, which cannot be adjusted according to the specific situation. Therefore, we propose a high-strength sponge silicone foam tube with strength adjustment function. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a high-strength silicone foam product to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength sponge silicone foam product, comprising a sponge silicone foam tube, wherein the interior of the sponge silicone foam tube has multiple sets of annularly distributed cavities, and each set of cavities is equipped with a strength adjustment structure. The strength adjustment structure includes a buffer part whose top end is fitted and connected to the inner wall of the sponge silicone foam tube, and a base for assisting the vertical movement of the buffer part is installed at the bottom end of the buffer part. Auxiliary support parts are fixed on both outer walls of the base, and the bottom end of the auxiliary support parts extends to the bottom outer wall of the cavity. The auxiliary support parts are triangular in shape.

[0006] By adopting the above technical solution, the hardness of the sponge silicone foam tube can be adjusted, thus adapting to different usage environments and making it highly practical.

[0007] The present invention is further configured such that a sliding cavity is provided inside the base, and a limiting slide plate is slidably connected in the sliding cavity, wherein the top end of the limiting slide plate is fixedly connected to the bottom end of the buffer part.

[0008] By adopting the above technical solution, the buffer section is effectively limited and buffered.

[0009] The present invention is further configured such that a bottom plate is provided below the limiting slide plate and is slidably connected to the inner wall of the slide cavity, and a return spring is connected between the bottom plate and the limiting slide plate, and the distance between the bottom end of the bottom plate and the bottom wall of the slide cavity is set.

[0010] By adopting the above technical solution, a driving effect is achieved on the base plate.

[0011] The present invention is further configured such that a lead screw is installed on both sides inside the sliding cavity, and the lead screw passes through the bottom plate and extends to the bottom end of the sliding cavity. A slider is sleeved on the outer wall of the lead screw, and the top end of the slider is fitted and connected to the bottom end of the bottom plate.

[0012] By adopting the above technical solution, the lead screw is driven.

[0013] The present invention is further configured such that a driven gear for driving the lead screw to rotate is installed at the bottom end of the lead screw, and a dial wheel extending to the outside of the base is meshed with one side of the driven gear.

[0014] By adopting the above technical solution, the driven gear is effectively driven.

[0015] In summary, the present invention has the following main advantages:

[0016] This invention, by setting up a strength adjustment structure, allows for the adjustment of the strength of the sponge silicone foam tube according to actual usage conditions. Specifically, by rotating the dial, the dial drives the driven gear to rotate, which in turn drives the lead screw to rotate. After the lead screw rotates, the slider on its outer wall moves upward, and the movement of the slider also pushes the base plate to move, causing the gap between the base plate and the limiting slide plate to decrease. At the same time, the return spring will undergo compression deformation when the gap between the base plate and the limiting slide plate decreases. As the spring compression gradually increases, the force causing further deformation is also greater, thus achieving the effect of increasing the strength of the buffer part, that is, increasing the strength of the sponge silicone foam tube. Conversely, the strength of the sponge silicone foam tube decreases when the gap is increased. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A high-strength silicone foam product, such as Figure 1-5 As shown, the device includes a sponge silicone foam tube 1. The sponge silicone foam tube 1 has multiple sets of annularly distributed cavities 2 inside, and each set of cavities 2 is equipped with a strength adjustment structure 3. The strength adjustment structure 3 includes a buffer part 32 whose top end is attached to the inner wall of the sponge silicone foam tube 1, and a base 31 for assisting the vertical movement of the buffer part 32 is installed at the bottom end of the buffer part 32. Auxiliary support parts 4 are fixed on both outer walls of the base 31, and the bottom end of the auxiliary support parts 4 extends to the bottom outer wall of the cavity 2. The auxiliary support parts 4 are triangular in shape.

[0026] Furthermore, in this embodiment, a sliding cavity is provided inside the base 31, and a limiting slide plate 6 is slidably connected in the sliding cavity. The top end of the limiting slide plate 6 is fixedly connected to the bottom end of the buffer part 32. A bottom plate 7 is provided below the limiting slide plate 6 and is slidably connected to the inner wall of the sliding cavity. A return spring 8 is connected between the bottom plate 7 and the limiting slide plate 6, and the distance between the bottom end of the bottom plate 7 and the bottom wall of the sliding cavity is set.

[0027] Please see Figure 5 Both sides of the slide cavity are equipped with lead screws 9, which pass through the base plate 7 and extend to the bottom of the slide cavity. A slider 10 is sleeved on the outer wall of the lead screw 9, and the top of the slider 10 is in contact with the bottom of the base plate 7 to achieve the driving effect on the base plate 7.

[0028] Please see Figure 4-5 The bottom end of the lead screw 9 is equipped with a driven gear 11 for driving the lead screw 9 to rotate, and a dial 5 extending to the outside of the base 31 is meshed with one side of the driven gear 11 to achieve the driving effect of the driven gear 11.

[0029] The working principle of this utility model is as follows: When using the sponge silicone foam tube 1, the strength of the sponge silicone foam tube 1 can be adjusted according to the actual usage. Specifically, by rotating the dial wheel 5, the dial wheel 5 will drive the driven gear 11 to rotate. After the driven gear 11 rotates, it will drive the lead screw 9 to rotate. After the lead screw 9 rotates, the slider 10 on its outer wall will move upward. The movement of the slider 10 will also push the base plate 7 to move, causing the gap between the base plate 7 and the limiting slide plate 6 to become smaller. At the same time, the return spring 8 will undergo compression deformation when the gap between the base plate 7 and the limiting slide plate 6 becomes smaller. As the compression of the return spring 8 gradually increases, the force of its further deformation will also be greater. Therefore, the effect of increasing the strength of the buffer part 32 is achieved, that is, the effect of increasing the strength of the sponge silicone foam tube 1 is achieved. Conversely, the strength of the sponge silicone foam tube 1 decreases.
