[0002] Silicone rubber is a material similar to ointment, which will solidify into a tough rubber-like solid once it comes into contact with moisture in the air. It is mainly divided into acetic acid removal type, alcohol removal type, ammonia removal type, and propyl removal type. Because silicone rubber is often used for bonding and sealing in the glass field, it is commonly known as glass glue. One-component silicone glass glue is a material similar to ointment, which will solidify into a tough rubber-like solid once it comes into contact with moisture in the air.

The top of the support base is fixedly connected with a support rod. A return spring is arranged at the bottom of the support rod. The outer wall of the support rod is movably connected with a bottom plate. This experimental device for testing the strength of silicone rubber, through the set support base, support frame, hydraulic mechanism, top plate, connecting rope, support rod, return spring, bottom plate and guide wheel, facilitates driving the bonded objects to slide up and down respectively, and then effectively detecting the strength of the silicone rubber through the applied tensile force, improving the overall detection efficiency and solving the problem of low detection efficiency.

[0004] In order to test the strength limit of silicone rubber, existing strength detection devices usually pull and separate two objects fixed by silicone rubber, causing the silicone rubber to be broken by the tensile force. When the silicone rubber breaks, the upper object has a large rebound force and is easy to rise and hit the tensile force counter, resulting in damage. Therefore, there is an urgent need in the market to develop an experimental device for testing the strength of silicone rubber to help people solve existing problems. Content of the Utility Model

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1-4, an embodiment provided by the present utility model: an experimental device for testing the strength of silicone glue, including a detection table 1. On both sides of the middle part of the upper end of the detection table 1, lower fixing plates 101 are fixedly connected. Between the two lower fixing plates 101, a lower fixed object 2 is arranged. At the front and rear ends of both sides of the upper end of the detection table 1, support columns 102 are fixedly connected. At the upper ends of the four support columns 102, a support plate 3 is fixedly connected. In the middle of the upper end of the support plate 3, a hydraulic rod 4 is fixedly connected. The telescopic end of the hydraulic rod 4 passes through the support plate 3 and extends to the lower end and is fixedly connected with a tensile counter 401. At the front and rear ends of both sides of the lower end of the support plate 3, buffer cylinders 302 are fixedly connected. At the lower ends of the four buffer cylinders 302, a lifting plate 5 is connected. On both sides of the middle part of the lower end of the lifting plate 5, upper fixing plates 501 are fixedly connected. Between the two upper fixing plates 501, an upper fixed object 6 is arranged.

[0024] Furthermore, between the two lower fixing plates 101 and the lower fixed object 2, they are fixedly connected by a first screw 201. The lower fixed object 2 is clamped by the two lower fixing plates 101 and fixed by the first screw 201, so that the lower fixed object 2 remains stationary during detection. By disassembling the first screw 201, the lower fixed object 2 can be separated from the lower fixing plates 101, facilitating the replacement of the lower fixed object 2.

[0025] Furthermore, at the front and rear ends of both sides of the upper end of the lifting plate 5, fixing rods 502 are fixedly connected. At the upper end inside the buffer cylinder 302, a spring 303 is fixedly connected.

[0026] Furthermore, the upper end of the fixing rod 502 extends into the buffer cylinder 302 and is fixedly connected with a guiding member 503. When the silicone glue is broken by the tensile force, the lifting plate 5 rebounds upward, causing the upper end of the fixing rod 502 to gradually insert into the buffer cylinder 302 and compress the spring 303. The spring 303 absorbs the upward rebound force of the lifting plate 5, reducing the degree of upward rebound of the lifting plate 5 and preventing the lifting plate 5 from hitting the tensile counter 401 and causing damage.

[0027] Furthermore, between the lower end of the tensile counter 401 and the middle part of the upper end of the lifting plate 5, they are connected by a pull rope 402. The upper end of the lower fixed object 2 and the lower end of the upper fixed object 6 are bonded by silicone glue. The hydraulic rod 4 is used to pull the tensile counter 401, so that the tensile counter 401 pulls the lifting plate 5 to rise through the pull rope 402, causing the upper fixed object 6 to rise and applying a tensile force to the silicone glue, realizing the strength detection of the silicone glue.

[0028] Furthermore, at the front and rear ends of both sides of the middle part of the lower end of the support plate 3, limit columns 301 are fixedly connected. The limit columns 301 limit the rising amplitude of the lifting plate 5, preventing the rebound force of the lifting plate 5 from being too large and directly hitting the tensile counter 401.

[0029] Furthermore, the two upper fixing plates 501 and the upper fixture 6 are fixedly connected by a second screw 601. The upper fixture 6 is clamped by the two upper fixing plates 501 and fixed by the second screw 601, so that the upper fixture 6 remains stationary on the lifting plate 5 during detection. By removing the second screw 601, the lower fixing plate 101 can separate the lower fixture 2, facilitating the replacement of the lower fixture 2.

[0030] Working principle: During use, after the upper end of the lower fixture 2 and the lower end of the upper fixture 6 are bonded with silicone glue, the two upper fixing plates 501 clamp the upper fixture 6 and fix it with the second screw 601, so that the upper fixture 6 remains stationary on the lifting plate 5 during detection. By removing the second screw 601, the lower fixing plate 101 can separate the lower fixture 2, facilitating the replacement of the lower fixture 2. The two lower fixing plates 101 and the lower fixture 2 are fixedly connected by a first screw 201. The lower fixture 2 is clamped by the two lower fixing plates 101 and fixed by the first screw 201, so that the lower fixture 2 remains stationary during detection. By removing the first screw 201, the lower fixing plate 101 can separate the lower fixture 2, facilitating the replacement of the lower fixture 2. The hydraulic rod 4 pulls the tension counter 401, so that the tension counter 401 pulls the lifting plate 5 to rise through the pull rope 402, causing the upper fixture 6 to rise and applying a tensile force to the silicone glue, realizing the strength detection of the silicone glue. Both the front and rear ends on both sides of the upper end of the lifting plate 5 are fixedly connected with fixing rods 502. A spring 303 is fixedly connected to the upper end inside the buffer cylinder 302. The upper end of the fixing rod 502 extends into the buffer cylinder 302 and is fixedly connected with a guide member 503. When the silicone glue is broken by the tensile force, the lifting plate 5 rebounds upward, causing the upper end of the fixing rod 502 to gradually insert into the buffer cylinder 302 and compress the spring 303. The spring 303 absorbs the upward rebound force of the lifting plate 5, reducing the degree of upward rebound of the lifting plate 5 and preventing the lifting plate 5 from hitting the tension counter 401 and causing damage. Both the front and rear ends on both sides of the middle part of the lower end of the support plate 3 are fixedly connected with limit posts 301. The rising amplitude of the lifting plate 5 is limited by the limit posts 301, preventing the rebound force of the lifting plate 5 from being too large and directly hitting the tension counter 401.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
