[0027] See also Figure 1-4 , an embodiment provided by the utility model:

[0028] A dry metrology furnace, comprising:

[0029] A metering furnace body 1, a temperature control port 17 is arranged on the top of the metering furnace body 1, an external temperature probe 7 is plugged into the temperature control port 17, a fixing frame 11 is fixedly installed on the top of the metering furnace body 1 on one side of the temperature control port 17, a threaded rod 14 is rotatably installed inside the fixing frame 11, a motor 13 is fixedly installed on the back of the fixing frame 11, and a driving end of the motor 13 passes through the back of the fixing frame 11 and extends to the inside of the fixing frame 11 and is fixedly connected to the rear end of the threaded rod 14;

[0030] An adjusting block 16 is sleeved on the outer wall of the threaded rod 14, a limiting block 15 is fixedly installed on one side of the adjusting block 16, a limiting groove 18 is provided on the inner wall of the fixing frame 11, and the limiting groove 18 is slidably connected to the limiting block 15, the adjusting block 16 is fixedly installed with an electric telescopic rod 9 through a mounting groove provided on one side of the top thereof, an extension arm 8 is fixedly installed on the driving end of the electric telescopic rod 9, and a collar 10 is fixedly installed on one end of the extension arm 8.

[0031] Both sides of the bottom of the metering furnace body 1 are fixedly installed with symmetrically distributed universal wheels 5, and both sides of the bottom of the metering furnace body 1 are fixedly installed with symmetrically distributed support frames 4. The support frames 4 are threadedly connected with adjusting screw rods 3 through threaded holes opened thereon, and a pressure plate 6 is rotatably installed at the bottom end of the adjusting screw rod 3, and a hand wheel 2 is fixedly installed at the top end of the adjusting screw rod 3.

[0032] In one of the embodiments, an anti-skid pad is bonded to the bottom of the pressing plate 6, which increases the friction between the pressing plate and the ground, thereby further enhancing the stability of the device when it is used at a fixed point.

[0033] In one preferred embodiment, a plurality of balls 19 are movably mounted on the inner wall of the collar 10, so that when the external temperature probe 7 passes through the inside of the collar 10, the elongated portion at the bottom of the external temperature probe 7 comes into rolling contact with the balls 19 on the inner wall of the collar 10 when it comes into contact with the inside of the collar 10. This design can effectively reduce the large friction between the external temperature probe 7 and the collar 10, thereby avoiding damage to the elongated portion at the bottom of the external temperature probe 7. This rolling contact mechanism protects the external temperature probe 7, prolongs its service life, and also improves the reliability and stability of the device.

[0034] In one embodiment, a threaded hole matched with the threaded rod 14 is provided on the front side of the adjusting block 16 , and the adjusting block 16 is threadedly connected to the threaded rod 14 through the threaded hole provided on the front side.

[0035] In one of the preferred embodiments, a handle 12 is fixedly installed on the top of the metering furnace body 1 on one side of the fixing frame 11. The installation of the handle 12 allows the staff to easily grasp and lift the metering furnace body 1, thereby facilitating the transportation and movement of the equipment.

[0036] The working principle of the utility model is as follows: in the process of using the external temperature probe 7, the motor 13 is first controlled by the switch to start working, and the driving end of the motor 13 drives the threaded rod 14 to rotate, and the threaded transmission between the threaded rod 14 and the adjusting block 16, and the sliding relationship between the adjusting block 16 and the limiting groove 18 through the limit block 15, so that the adjusting block 16 can stably move longitudinally, and the movement of the adjusting block 16 drives the extension arm 8 to move through the electric telescopic rod 9, and the movement of the extension arm 8 drives the collar 10 to move, and the collar 10 is quickly moved to the top of the temperature control port 17, and then the electric telescopic rod 9 is controlled by the switch to start working, and the driving end of the electric telescopic rod 9 drives the extension arm 8 to move vertically, and the movement of the extension arm 8 drives the collar 10 to move, and the height of the collar 10 above the temperature control port 17 is adjusted, and then the external temperature probe 7 is inserted into the inside of the collar 10 through the inside of the limit block 15, so that the external temperature probe 7 can be put down vertically, thereby effectively protecting the slender part at the bottom thereof and avoiding damage. The adjustment method of the collar 10 adopts a mechanical drive method, which means that there is no need for manual slow adjustment. Instead, the staff can quickly adjust the position of the collar 10 by simply pressing the control button. This design facilitates the staff to quickly insert the external temperature probe 7, significantly improving the efficiency of the equipment.

[0037] When the equipment is in use, the universal wheel 5 is in rolling contact with the ground, which makes it convenient to move the equipment, thereby improving the convenience of people in using the equipment. At the same time, when the equipment is in a stationary position, the staff can turn the hand wheel 2, and the rotation of the hand wheel 2 drives the adjusting screw 3 to rotate, and the adjusting screw 3 is driven by the threaded transmission of the supporting frame 4 to make the adjusting screw 3 move vertically. The movement of the adjusting screw 3 drives the pressure plate 6 to move, so that the pressure plate 6 moves downward and contacts the ground, thereby increasing the contact area and friction between the equipment and the ground when the equipment is in a stationary position, ensuring the stability of the device during use, and having extremely high practicality. In addition, the electrical components appearing in the present application are all externally connected to the power supply and the control switch on the metering furnace body 1 when in use, and the parts not involved in the equipment are the same as the prior art or can be implemented by the prior art.

[0038] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
