Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a fixing device for a temperature detection probe of a constant temperature drying oven. Background Technology

[0002] In the inspection of finished cigarette products, a constant temperature drying oven is required to test the moisture content of the tobacco. When the test data is abnormal or the equipment is under maintenance, a multi-channel temperature measuring instrument must be used according to standard methods to fix multiple temperature probes in designated positions within the constant temperature drying oven for periodic temperature verification. The temperature probe consists of a 3mm diameter high-temperature resistant round wire connected to a 6mm diameter, 40mm long cylindrical platinum resistance probe. The constant temperature drying oven support consists of several chrome-plated cylindrical supports spaced 15mm apart, 2mm in diameter, and 600mm long. Since there is currently no dedicated clamping device on the market that fits the constant temperature drying oven support and temperature probes, ordinary wooden clips or metal folders must be used to clamp the bottom round wire of the temperature probe onto the chrome-plated cylinders of the constant temperature drying oven for measurement. Figure 1 As shown, a metal folder is used to hold the temperature detection probe. However, during the holding process, the following problems occur: the holding operation is difficult, time-consuming and laborious, and ordinary clips are prone to sliding on the chrome-plated cylinder, making it impossible to firmly fix the temperature detection probe. This causes the temperature detection probe or wire to deviate significantly from the designated measurement point during measurement. When the temperature detection probe is found to be deviated, it needs to be re-clamped. Therefore, there is an urgent need to invent a temperature detection probe fixing device that has a high degree of fit with the constant temperature drying oven bracket and provides strong fixation of the temperature detection probe. Utility Model Content

[0003] In view of the problems existing in the background technology, the present invention aims to provide a temperature detection probe fixing device that has a high degree of fit with the constant temperature drying oven bracket, provides strong fixation of the temperature detection probe, and is easy to clamp.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A temperature detection probe fixing device for a constant temperature drying oven includes a probe wire clamping part and a tray frame clamping part;

[0006] The probe wire clamping part includes an upper connecting plate and a clamping support plate. The upper connecting plate and the clamping support plate are connected to form an obtuse angle structure. At least two wire clamps are provided on the clamping support plate. The wire clamps are arranged vertically and located on the same vertical line.

[0007] The pallet rack clamping part includes a pallet fixing plate, which is connected to the upper connecting plate to form an acute angle structure, and the clamping support plate is perpendicular to the pallet fixing plate. At least two fixing clamps are provided on the bottom surface of the pallet fixing plate. A wire hole is also provided on the pallet fixing plate, and the wire hole and the wire clamp are located on the same vertical line.

[0008] Furthermore, it also includes a lower extension, which includes a lower connecting plate and an extension base plate. The two ends of the lower connecting plate are respectively connected to the tray fixing plate and the extension base plate, and the extension base plate is also provided with a bottom groove.

[0009] Furthermore, the upper connecting plate and the clamping support plate, the pallet fixing plate and the upper connecting plate, the pallet fixing plate and the lower connecting plate, and the lower connecting plate and the extension base plate are all connected by R-angle welding.

[0010] Furthermore, the wire clamp is connected to the wire of the temperature detection probe, and the fixing clamp is connected to the tray frame.

[0011] Furthermore, both the wire clamp and the fixing clamp are hollow circular tube structures, and a notch is provided along the length direction of the circumference of the hollow circular tube.

[0012] Furthermore, the upper connecting plate, clamping support plate, pallet fixing plate, lower connecting plate, and extension base plate are all made of chrome-plated stainless steel, and the included angle between the upper connecting plate and the pallet fixing plate is 30°.

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

[0014] The fixing device provided by this utility model is easy to operate, low in manufacturing cost, sturdy, durable, and highly heat-resistant. It uses a three-section clip-on fixing method to firmly secure the connecting wire of the temperature detection probe. After fixing, the connecting wire is not prone to shifting or falling off, and it is easy to fix and remove, ensuring high reliability. The use of this fixing device improves the stability of the multi-channel temperature measuring instrument's temperature detection probe when fixed in the designated position during verification in the constant temperature drying oven, enhances the reliability of verification data during the constant temperature drying oven period, and avoids the influence of pulling on the temperature detection probe connecting wire when the oven door is closed, significantly improving the efficiency of verification and subsequent testing tasks during the constant temperature drying oven period.

[0022] refer to Figure 2-3 As shown, this utility model provides a temperature detection probe fixing device for a constant temperature drying oven, including a probe wire clamping part 1 and a tray frame clamping part 2;

[0023] The probe wire clamping part 1 includes an upper connecting plate 11 and a clamping support plate 12. The upper connecting plate 11 and the clamping support plate 12 are connected to form an obtuse angle structure. Preferably, the clamping support plate 12 is a rectangular surface with a length of 30 mm and a width of 10 mm, and the upper connecting plate 11 is a rectangular surface with a length of 20 mm and a width of 10 mm. At least two wire clamps 13 are provided on the clamping support plate 12. The wire clamps 13 are arranged vertically and located on the same vertical line. The wire clamps 13 are used to clamp the wire part of the temperature detection probe.

[0024] The pallet frame clamping part 2 includes a pallet fixing plate 23, which is connected to the upper connecting plate 11 to form an acute angle structure. Preferably, the pallet fixing plate 23 is a rectangular surface with a length of 25mm and a width of 10mm. The clamping support plate 12 is perpendicular to the pallet fixing plate 23. At least two fixing clips 22 are provided on the bottom surface of the pallet fixing plate 23. The width of the fixing clips 22 is equal to that of the pallet fixing plate 23, which is 10mm. The fixing clips 22 are used to clamp the two rods of the pallet frame. Therefore, in the design, the spacing of the fixing clips 22 needs to be determined according to the spacing between two adjacent rods of the pallet frame. A wire hole 21 is also provided on the pallet fixing plate 23. The wire hole 21 and the wire clamp 13 are located on the same vertical line. In actual use, the wire of the temperature detection probe needs to be passed through the wire hole 21.

[0025] In addition, the device also includes a lower extension 3, which includes a lower connecting plate 31 and an extension base plate 32. The lower connecting plate 31 and the extension base plate 32 are connected to form an L-shape. The two ends of the lower connecting plate 31 are respectively connected to the tray fixing plate 23 and the extension base plate 32. The extension base plate 32 is also provided with a bottom groove 33. Preferably, the specific dimensions are as follows: the lower connecting plate 31 is a rectangular surface with a length of 12mm and a diameter of 10mm; the extension base plate 32 is a rectangular surface with a diameter of 20mm and a width of 10mm; and the bottom groove 33 is a right rectangular notch with a diameter of 10mm and a width of 3.5mm.

[0026] To improve the strength of the device and prevent bending and deformation, the upper connecting plate 11 and the clamping support plate 12, the pallet fixing plate 23 and the upper connecting plate 11, the pallet fixing plate 23 and the lower connecting plate 31, and the lower connecting plate 31 and the extension base plate 32 are all welded together by R-angle 4. R-angle 4 is a metal strip with a certain curvature. Compared with directly bending the metal plate, welding together by R-angle 4 can ensure that the included angle between each surface remains unchanged and the service life is also longer.

[0027] The wire clamp 13 is connected to the wire of the temperature detection probe, and the fixing clamp 22 is connected to the tray frame. To achieve this technical effect, both the wire clamp 13 and the fixing clamp 22 are hollow cylindrical structures with a notch along the length of the circumference of the hollow cylindrical structure. Preferably, the wire clamp 13 is a hollow cylinder with a diameter of 3.5 mm, a length of 5 mm, and a notch facing to the left, and the fixing clamp 22 is a hollow cylinder with a diameter of 2.5 mm, a length of 10 mm, and a notch facing downwards.

[0028] The upper connecting plate 11, clamping support plate 12, pallet fixing plate 23, lower connecting plate 31 and extension base plate 32 are all chrome-plated stainless steel with a thickness of 1.5mm. The included angle between the upper connecting plate 11 and the pallet fixing plate 23 is 30°.

[0029] When fixing the temperature detection probe using this device, pass the wire of the temperature detection probe through the bottom wire groove 33 and the wire hole 21, and insert the upper part of the wire into the wire clamp 13. Then, insert the fixing clip 22 at the bottom of the tray fixing plate 23 into the tray frame to complete the fixing.
