Description

Technical Field

[0001] The utility model belongs to the technical field of a sealant high temperature resistance testing device, and more specifically, particularly relates to a sealant high temperature resistance testing device. Background Art

[0002] Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the gap in the structure to achieve a sealing effect. It has the functions of preventing leakage, waterproofing, anti-vibration, sound insulation, and heat insulation.

[0003] Some current sealant high temperature resistance testing devices require the sealant to be squeezed into strips before testing, and then after it is air-dried, it is placed in the testing device for long-term high-temperature heating. After the heating is completed and cooled, the sealant is taken out and its performance is tested with the help of tools. However, this detection method is difficult to directly detect the performance of the sealant under high temperature conditions, resulting in incomplete test results. At the same time, the staff needs to wait for the sealant to cool down before taking it out for testing, which increases the waiting time and reduces the detection efficiency. In addition, the sealant will produce odors during the heating process. After the staff opens the door of the testing device, these odors will enter the external environment, polluting the working environment and endangering the health of the staff.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a sealant high temperature resistance testing device is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sealant high temperature resistance testing device, which is achieved by the following specific technical means:

[0006] The high temperature resistance testing device of sealant comprises a testing box, a sliding groove is provided on the bottom end surface of the testing box, a bidirectional screw rod is rotatably connected in the sliding groove, a pair of sliding blocks are connected through both ends of the bidirectional screw rod, a supporting block is installed on the top of the pair of sliding blocks, a tension sensor is installed on one side of the upper end of the pair of supporting blocks, a mounting block is installed on one side of the tension sensor, a groove is provided on one side of the mounting block, a threaded groove is provided on the top of the groove, a screw rod is threadedly connected in the threaded groove, a clamping block is installed on the bottom end of the screw rod, a heating plate is installed at the middle position of the top of the testing box, a pair of ventilation pipes are installed on both sides of the heating plate at the top of the testing box, a blowing head is installed at the bottom end of the ventilation pipe, a ventilation groove is provided on the top of the testing box above the pair of ventilation pipes, a pair of exhaust holes are provided on both sides of the testing box, an exhaust fan is installed in the exhaust hole, and a filter is installed on the side of the exhaust hole close to the exhaust fan.

[0007] Furthermore, a chamber is provided on one side of the slide slot, a motor is installed in the chamber, and one end of the bidirectional lead screw passes through one side of the slide slot and is connected to an output end of the motor.

[0008] Furthermore, a rotating block is installed at the top end of the screw.

[0009] Furthermore, an air pump is installed on the upper end surface of the test box above the ventilation slot, and the air pump is connected to the ventilation slot.

[0010] Furthermore, a box door is installed on one side of the test box.

[0011] Furthermore, a controller is installed on one side of the test box close to one of the exhaust holes.

[0012] Furthermore, the bidirectional screw is threadedly connected to the slider.

[0013] Furthermore, the bottom of the ventilation slot is connected to the ventilation pipe.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] By using the heating plate, motor, bidirectional screw rod, slider, support block, tension sensor and mounting block in coordination, the heating plate is started to heat the sealant. When heated to a certain degree, the motor is started, and the motor drives the bidirectional screw rod to rotate. The bidirectional screw rod drives a pair of sliders to move to both sides through the rotation. The slider drives the tension sensor to move to both sides through the support block. When the tension sensor moves to both sides, it stretches the sealant through the mounting block, so that the performance of the sealant can be tested at high temperature, thereby improving the comprehensiveness of the test results.

[0016] Through the coordinated use of the air pump, ventilation slots, ventilation pipes and air blowing heads, when the performance test of the sealant is completed, the air pump is started, and the air pump conveys cold air to the ventilation pipes through the ventilation slots. The ventilation pipes blow the cold air to the equipment in the test box through the air blowing heads, thereby quickly cooling down the equipment, thereby reducing the waiting time for the next sealant test and improving the test efficiency.

[0017] Through the coordinated use of the exhaust fan and the filter, when the temperature in the test box is lowered, the exhaust fan is started to discharge the high-temperature gas in the test box. At the same time, the filter in the exhaust pipe can filter out the odor in the gas, thereby preventing the odorous gas from directly entering the external environment, reducing the pollution to the working environment and the harm to the health of the staff, and improving the environmental performance of the device.
