Description

Technical Field

[0001] This utility model belongs to the field of furnace temperature tester insulation, specifically relating to a multifunctional furnace temperature tester insulation box. Background Technology

[0002] The heat insulation box is an important component of the furnace temperature tester. Its main function is to insulate and protect the furnace temperature tester from high-temperature damage. Because the internal temperature of any furnace temperature tester is not very high, for example, the operating temperature range of our Bride furnace temperature tester is -40 to 105℃. If the temperature inside the heat insulation box exceeds the range that the furnace temperature tester can withstand, the furnace temperature tester will automatically shut down, which serves as a self-protection function. In severe cases, it may burn out the mainboard of the furnace temperature tester.

[0003] Existing insulation boxes have a high degree of structural sealing to ensure insulation performance, which makes installation and disassembly more troublesome. In addition, the thermal expansion and contraction of the internal structure of the insulation box results in a short lifespan. Utility Model Content

[0004] This utility model provides a heat insulation box for a multi-functional furnace temperature tester to solve the technical problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, the present invention provides a multifunctional furnace temperature tester heat insulation box, including a base, a ferrule, and a constraint sleeve. A heat insulation groove is provided at the upper center of the base, and the tester body is provided in the heat insulation groove. The tester body is electrically connected to an external power supply. The ferrule is disposed above the base, and the ferrule and the base are disposed inside the constraint sleeve. A buffer is fixedly installed on the outside of the constraint sleeve, and the buffer is used to constrain the position of the base and the ferrule.

[0006] Preferably, the heat insulation groove is provided with a ceramic pad, the ceramic pad is in contact with the tester body, and the ferrule is a ceramic component.

[0007] Preferably, the sum of the height of the ceramic pad and the height of the tester body is consistent with the height of the heat insulation groove, that is, the upper surface of the tester body is flush with the heat insulation groove.

[0008] Preferably, a locking block is fixedly installed on the outer side of both the sleeve and the base. Multiple locking blocks are provided and arranged symmetrically. A locking groove is opened on the inner side of the constraint sleeve, and the locking block is engaged in the locking groove.

[0009] Preferably, the width of the card slot is greater than twice the width of the card block.

[0010] Preferably, the buffer includes a sleeve, the bottom of the constraint sleeve has a through hole, the sleeve is fixedly installed in the through hole, the inner wall of the sleeve is machined with internal threads, and the outer side of the sleeve is provided with an adjusting bolt, which is engaged with the sleeve.

[0011] Preferably, a fixing block is fixedly installed at the middle position of the sleeve, a sliding rod is fixedly installed on the outside of the fixing block, a buffer spring is fixedly installed at the bottom of the sliding rod, and a constraint pad is fixedly installed at the bottom of the buffer spring.

[0012] Preferably, there are two slide rods arranged symmetrically. A limiting block is fixedly installed on the top of each slide rod, and a return spring is provided between the limiting block and the fixing block. The return spring is sleeved on the outside of the slide rod.

[0013] This invention has the following advantages over the prior art:

[0014] 1. The multifunctional furnace temperature tester insulation box of this utility model is used by placing the tester body in the insulation groove. A ceramic pad is provided between the tester body and the base to improve the heat insulation effect. The ferrule is aligned with the base, and the ferrule blocks on both sides of the base and the ferrule are inserted into the slots on the inner side of the constraint sleeve. The slots can constrain and limit the base and the ferrule. At the same time, a buffer is provided on the outer side of the constraint sleeve. The buffer can fix the ferrule and the base. It has high stability, good sealing, and is simple to install and easy to disassemble.

[0015] 2. The heat insulation box of the multifunctional furnace temperature tester of this utility model allows for the adjustment of the adjusting bolt. The adjusting bolt rotates and moves downward along the inner thread of the sleeve, pressing the limiting block. The limiting block drives the sliding rod to move downward, and the sliding rod pushes the constraint pad to press against the back of the base, which can fix the base and the sleeve, resulting in a higher fixing effect. At the same time, during the temperature measurement process, a buffer spring is provided between the constraint pad and the sliding rod, so that there is a buffer zone between the constraint pad and the sliding rod. This ensures that under high temperature expansion, stress can be released between the sleeve, the base and the constraint sleeve, improving the overall service life. Attached Figure Description
