Description

Technical Field

[0001] This utility model relates to the field of rubber sealing strip testing technology, and in particular to a sample testing device. Background Technology

[0002] Sample testing equipment is used to simulate various environmental conditions to test the performance, durability, and reliability of products or materials under different environments. These devices are widely used in many fields, including aerospace, automotive, electronics, military, and medical, to ensure that products or materials meet expected performance requirements in actual use; rubber sealing strips produced require sample testing equipment to test their tensile strength and fire resistance.

[0003] Previous sample testing devices have the following drawbacks: 1. They are not convenient for detecting the maximum tensile force that the sample can withstand upon fracture, and they cannot test the fire resistance of the sealing strip sample. Therefore, those skilled in the art have provided a sample testing device to solve the problems mentioned in the background art. Utility Model Content

[0004] The main objective of this invention is to provide a sample testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sample testing device includes a base, a testing platform, and a gantry.

[0007] A test platform is mounted on the top of the base via a support frame. Electric slide rails are mounted on both sides of the top of the test platform via screws, and an electric slider slides within the slide rails. A gantry frame is bolted to the top of the electric slider. An electric cylinder is mounted on the top of the gantry frame via a mounting base, and the bottom output shaft of the electric cylinder is connected to a U-shaped clamp via screws. A tension gauge is mounted on one end of the electric slide rails via a mounting plate, and a U-shaped clamp is mounted on the top detection end of the tension gauge via screws. A burner is connected to the other end of the electric slide rails via a connecting plate. A timer is mounted on one side of the top of the gantry frame via screws.

[0008] As a further improvement of this utility model: an L-shaped support plate is installed at one end of the test bench by screws, and a U-shaped block is welded to one side of the top of the L-shaped support plate.

[0009] As a further improvement of this utility model: a rotating block is connected inside the U-shaped block via a damping shaft, and a camera is mounted on one side of the rotating block via screws.

[0010] As a further improvement of this utility model: a locking bolt is installed on one side of the U-shaped clamp through a screw hole, and the inner end of the locking bolt is connected to the clamping block through a bearing. The inner side of the clamping block is provided with anti-slip texture. Tightening the locking bolt moves the clamping block to one end, which facilitates clamping and fixing the sealing strip sample. The anti-slip texture has an anti-slip effect and better stability.

[0011] As a further improvement of this utility model, each bottom corner of the base is equipped with a brakeable omnidirectional wheel by bolts.

[0012] As a further improvement of this utility model: the bottom input end of the burner is connected to a fuel pipe and a control valve is provided on the fuel pipe. Opening the control valve allows fuel to be introduced into the burner through the fuel pipe for easy ignition, and controls the size of the flame to avoid damaging the electric cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The brakeable casters facilitate the movement of the entire testing device to a designated position. The electric cylinder drives the U-shaped clamp on the output shaft to move downwards, clamping both ends of the cut sealing strip sample between the electric cylinder and the tension gauge respectively. The output shaft of the electric cylinder retracts, causing the sealing strip sample between the U-shaped clamps to be pulled until it breaks. The tension gauge is used to easily detect the maximum tensile force that the sample can withstand when it breaks.

[0015] 2. After the test is completed, use the electric slider to slide in the electric slide rail to make it easy to slide the gantry frame directly above the burner. Clamp the sealing strip sample in the U-shaped clamp on the output shaft of the electric cylinder. Open the control valve to use the fuel pipe to introduce fuel into the burner for easy ignition and control the size of the flame to avoid damaging the electric cylinder, thereby testing the fire resistance effect of the sealing strip sample.

[0022] Please see Figure 1-3 In this embodiment of the present invention, a sample testing device includes a base 2, a testing platform 4, and a gantry frame 8;

[0023] A test platform 4 is mounted on the top of the base 2 via a support frame 3. Electric slide rails 5 are mounted on both sides of the top of the test platform 4 via screws, and an electric slider 14 slides inside the electric slide rails 5. A gantry frame 8 is mounted on the top of the electric slider 14 via bolts. An electric cylinder 9 is mounted on the top of the gantry frame 8 via a mounting seat, and the bottom output shaft of the electric cylinder 9 is connected to a U-shaped clamp 7 via screws. A tension gauge 15 is mounted on one end of the electric slide rails 5 via a mounting plate. A U-shaped clamp 7 is mounted on the top detection end of the tension gauge 15 via screws. A burner 19 is connected to the other end of the electric slide rails 5 via a connecting plate. A timer 6 is mounted on one side of the top of the gantry frame 8 via screws.

[0024] One end of the test bench 4 is fitted with an L-shaped support plate 13 by screws, and a U-shaped block 11 is welded to one side of the top of the L-shaped support plate 13; the U-shaped block 11 facilitates the connection of the rotating block 10 through the damping shaft.

[0025] The U-shaped block 11 is connected to a rotating block 10 via a damping shaft. A camera 12 is mounted on one side of the rotating block 10 via screws. The rotating block 10 rotates within the U-shaped block 11, which facilitates the adjustment of the shooting angle of the camera 12.

[0026] Among them, a locking bolt 16 is installed on one side of the U-shaped clamp 7 through a screw hole. The inner end of the locking bolt 16 is connected to the clamping block 17 through a bearing. The inner side of the clamping block 17 is provided with anti-slip texture 18. Tightening the locking bolt 16 will move the clamping block 17 to one end, which will facilitate the clamping and fixing of the sealing strip sample. The anti-slip texture 18 has an anti-slip effect and better stability.

[0027] Among them, the bottom corners of the base 2 are all equipped with brakeable casters 1 by bolts; the brakeable casters 1 make it easy to move the whole detection device to the designated position for use.

[0028] The burner 19 has a fuel pipe 21 connected to its bottom input end, and a control valve 20 is installed on the fuel pipe 21. Opening the control valve 20 allows fuel to be introduced into the burner 19 through the fuel pipe 21 for easy ignition, and controls the size of the flame to avoid damaging the electric cylinder 9.

[0029] The working principle of this utility model is as follows: The brakeable universal wheel 1 facilitates the movement of the entire testing device to a designated position. The electric cylinder 9 drives the U-shaped clamp 7 on the output shaft to move downwards, clamping both ends of the cut sealing strip sample between the electric cylinder 9 and the tension gauge 15 respectively through the U-shaped clamp 7. The output shaft of the electric cylinder 9 retracts, causing the sealing strip sample between the U-shaped clamps 7 to be pulled until it breaks. The tension gauge 15 facilitates the detection of the maximum tensile force that the sample can withstand at the point of breakage. After the test is completed, the electric slider 14 slides within the electric slide rail 5, facilitating the sliding of the gantry 8 directly above the burner 19. The sealing strip sample is then clamped within the U-shaped clamp 7 on the output shaft of the electric cylinder 9. The control valve 20 is opened, and fuel is introduced into the burner 19 through the fuel pipe 21 for ignition and flame control to prevent damage to the electric cylinder 9. This process tests the fire resistance of the sealing strip sample. The camera 12 records the testing process for record-keeping purposes and for convenient remote playback.
