Description

Technical Field

[0001] This utility model relates to the technical field of insulated glass dew point testing devices, specifically an insulated glass dew point testing device. Background Technology

[0002] A dew point testing device for insulating glass disclosed in CN204964432U includes a dry ice canister, a frame with guide wheels at the bottom, and a canister rack for loading the dry ice canister. The upper part of the frame is a support frame for supporting the dry ice canister, and the lower part is a placement platform for placing the insulating glass to be tested. The canister rack is hinged to the support frame and fixed by a fixing component. The dry ice canister is placed upside down in the canister rack and opposite to the placement platform.

[0003] The dry ice canister is loaded onto the canister rack and placed on the frame. The frame can move horizontally via guide wheels at the bottom. The canister rack is hinged to the support frame, allowing the dry ice canister to be rotated as needed. This solves the problem of the existing dry ice canister being bulky and inconvenient to use during dew point testing. It also avoids the safety hazard of the dry ice canister tipping over when placed upright. In addition, when the dry ice canister is placed on the frame, it is opposite the platform on which the insulating glass to be tested is placed. After the dry ice is added to the dew point meter, the dew point test can be performed directly, making it convenient to use.

[0004] The technical solution in the prior art document facilitates the placement of dry ice canisters, but the positioning of the dry ice canisters is not secure enough. When rotating the canister rack, the dry ice canisters have bellows that can detach, and manual lifting of the dry ice canisters to the working height is required, which poses a safety hazard of falling. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hollow glass dew point testing device, which solves the problems of insufficiently secure positioning of dry ice canisters, the possibility of the dry ice canisters detaching during rotating the canister rack, and the need for manual lifting of the dry ice canisters to the working height, thus posing a safety hazard of falling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dew point testing device for insulating glass, comprising a testing platform, a lifting assembly fixedly connected to the top surface of the testing platform, a connecting rod fixedly connected to the side surface of the lifting assembly, and a positioning assembly fixedly connected to one end of the connecting rod;

[0007] The lifting assembly includes a slide groove fixedly connected to the top surface of the testing platform, a drive motor sleeved inside the slide groove, a lead screw fixedly connected to the output end of the drive motor, and a slider threadedly connected to the surface of the lead screw. The slider is slidably connected inside the slide groove.

[0008] The positioning assembly includes a support plate fixedly connected to the side of the slider, an extension rod fixedly connected to the top surface of the support plate, a fixing strap fixedly connected to one side of the extension rod, a double D-ring fixedly connected to one end of the fixing strap, a constraint strap fixedly connected to the other side of the extension rod, a female buckle sleeved in a sleeve hole at one end of the constraint strap, and a female buckle sleeved in the remaining sleeve holes of the constraint strap. The surface of the constraint strap has several sleeve holes.

[0009] In one specific embodiment, the constraint strap can pass through the double D-ring and then fold back, so that the female buckle is engaged and fixed with the female buckle at a designated position.

[0010] In one specific embodiment, when the drive motor drives the lead screw to rotate, it causes the slider to move linearly up and down along the slide groove.

[0011] In one specific embodiment, the lifting component drives the positioning component to rise and fall as a whole via a slider.

[0012] In one specific embodiment, the pallet carries the dry ice canister and adjusts its height synchronously during the lifting and lowering process.

[0013] In one specific embodiment, the snap-fit ​​position of the female buckle and the male buckle can be adjusted along the sleeve hole of the constraint strap to accommodate dry ice cans of different sizes.

[0014] Compared with the prior art, this utility model provides a dew point testing device for insulating glass, which has the following beneficial effects:

[0015] In the technical solution disclosed in this utility model, the design of the constraint band in the positioning component passing through the double D-ring and then folding back, combined with the female buckle and the female buckle engaging and fixing at a designated position on the constraint band, achieves a wrap-around restraint of the dry ice canister, significantly improving the fixing firmness and completely avoiding the hidden danger of the dry ice canister falling off during rotation as described in the prior art. At the same time, the drive motor of the lifting component drives the lead screw to rotate, causing the threaded slider to rise and fall linearly within the slide groove, so that the support plate fixed to the side of the slider automatically adjusts the height of the dry ice canister without manual lifting, fundamentally eliminating the safety risk of falling during operation. In addition, the several holes opened on the constraint band allow the female buckle to engage with the female buckle at different positions, enabling the positioning component to adapt to dry ice canisters of various sizes, expanding the applicability of the device.

[0016] The lifting and positioning components of this invention allow for the following steps: First, the dry ice canister is placed vertically on the support plate of the positioning component. The constraint strap, fixed to the other side of the extension rod, is manually pulled to pass through the double D-ring. After folding back the excess length of the constraint strap according to the diameter of the dry ice canister, a corresponding hole is selected on the surface of the constraint strap. The female buckle, fitted into the hole at the beginning of the constraint strap, is pressed into the female buckle in that hole, forming a ring-like fixation around the dry ice canister. Then, the drive motor of the lifting component is activated to drive the lead screw fixed to its output end to rotate. The engagement of the slider with the threaded connection causes the slider to rise or fall vertically along the groove fixed to the top surface of the test platform. Since the slider is fixedly connected to the positioning component by the connecting rod on the side, the support plate drives the fixed dry ice can to move synchronously to the required test height. At this time, the constraint band is always kept taut under the constraint of the double D buckle. After the dew point test is completed, the reverse drive motor resets the dry ice can. The can can be disassembled by releasing the snap fastener between the female and male buckles. Different diameter dry ice cans can be adapted by changing the position of the sleeve hole of the female buckle snap fastener on the constraint band. Attached Figure Description

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figures 1-4As an embodiment of the present invention, a dew point testing device for insulating glass includes a testing platform 1, a lifting assembly 2 fixedly connected to the top surface of the testing platform 1, a connecting rod 3 fixedly connected to the side surface of the lifting assembly 2, and a positioning assembly 4 fixedly connected to one end of the connecting rod 3.

[0025] The specific problem addressed in this embodiment is the lack of secure positioning of the dry ice canisters, which can detach during rotation of the canister rack, requiring manual lifting to the working height and posing a safety hazard of falling. This invention utilizes the design of the constraint band 45 in the positioning component 4, which passes through the double D-rings 44 and then folds back. This, combined with the female buckle 46 engaging with the designated female buckle 47 on the constraint band 45, achieves a wraparound restraint on the dry ice canister, significantly improving its stability and completely eliminating the risk of it falling during rotation as described in the prior art. Simultaneously, the drive motor 22 of the lifting component 2 drives the lead screw 23 to rotate, causing the threaded slider 24 to move linearly up and down within the groove 21. This allows the support plate 41 fixed to the side of the slider 24 to automatically adjust the height of the dry ice canister, eliminating the need for manual lifting and fundamentally eliminating the risk of falling during operation. Furthermore, the several holes on the constraint band 45 allow the female buckle 46 to engage with the female buckle 47 at different positions, enabling the positioning component 4 to adapt to various sizes of dry ice canisters and expanding the device's applicability.

[0026] The lifting assembly 2 includes a slide groove 21 fixedly connected to the top surface of the testing table 1, a drive motor 22 sleeved inside the slide groove 21, a lead screw 23 fixedly connected to the output end of the drive motor 22, and a slider 24 threadedly connected to the surface of the lead screw 23. The slider 24 is slidably connected inside the slide groove 21. The positioning assembly 4 includes a support plate 41 fixedly connected to the side of the slider 24, an extension rod 42 fixedly connected to the top surface of the support plate 41, a fixing strap 43 fixedly connected to one side of the extension rod 42, a double D buckle 44 fixedly connected to one end of the fixing strap 43, a constraint strap 45 fixedly connected to the other side of the extension rod 42, a female buckle 46 sleeved in the sleeve hole at one end of the constraint strap 45, and a male buckle 47 sleeved in the remaining sleeve holes of the constraint strap 45. The surface of the constraint strap 45 has several sleeve holes. In this specific embodiment, the constraint strap 45 can pass through the double D buckle 44 and then fold back, so that the female buckle 46 is engaged and fixed with the male buckle 47 at the designated position. First, place the dry ice can vertically on the support plate 41 of the positioning component 4. Manually pull the constraint strap 45, which is fixed to the other side of the extension rod 42, so that it passes through the double D buckle 44. After folding back the excess length of the constraint strap 45 according to the diameter of the dry ice can, select the corresponding position of the sleeve hole opened on the surface of the constraint strap 45. Press the female buckle 46, which is fitted into the sleeve hole at the first end of the constraint strap 45, into the female buckle 47 in the sleeve hole at that position to form a ring-shaped fixation for the dry ice can. Then, start the drive motor 22 of the lifting component 2 to drive the lead screw 23 fixed to its output end to rotate. The slider 24 connected to the threaded screw 23 rotates through the lead screw 23. The meshing action causes the slider 24 to rise or fall vertically along the slide groove 21 fixed to the top surface of the test platform 1. Since the side of the slider 24 is fixedly connected to the positioning component 4 through the connecting rod 3, the support plate 41 drives the fixed dry ice can to move synchronously to the required test height. At this time, the constraint band 45 is always kept taut under the constraint of the double D buckle 44. After the dew point test is completed, the reverse drive motor 22 resets the dry ice can, and the can can be disassembled by releasing the engagement between the female buckle 46 and the female buckle 47. The can can be adapted to dry ice cans of different diameters by changing the position of the sleeve hole of the female buckle 46 engaging with the female buckle 47 on the constraint band 45.

[0027] In this specific embodiment, when the drive motor 22 drives the lead screw 23 to rotate, it drives the slider 24 to move linearly up and down along the slide groove 21. When the drive motor 22 is powered on, its output end drives the fixedly connected lead screw 23 to rotate. Through the meshing action between the surface of the lead screw 23 and the threaded slider 24, the slider 24 is forced to move linearly up and down in the vertical direction along the inner wall of the slide groove 21 fixed to the top surface of the testing table 1. This mechanical transmission method replaces the manual lifting operation of the dry ice can, eliminating the risk of the can falling during manual handling. At the same time, the sliding constraint of the slide groove 21 on the slider 24 ensures that the lifting trajectory is accurate and without deviation, avoiding the problem of dry ice can shaking caused by the hinged rotation of the can frame in the comparison document.

[0028] In this specific embodiment, the support plate 41 carries the dry ice canister and adjusts its height synchronously during the lifting and lowering process. During the lifting and lowering of the slider 24 along the slide groove 21, the support plate 41, which is fixedly connected to the side of the slider 24, synchronously carries the dry ice canister to move vertically. Through the precise control of the lifting and lowering height by the drive motor 22, the dry ice canister is automatically positioned to the working height required for dew point testing. This design completely avoids the operation of manually lifting the canister to the frame support frame required in the comparison document. At the same time, the constraint strap 45 passes through the double D buckle 44 and is locked by the female buckle 46 and the female buckle 47 to form a ring-shaped fixation, ensuring that the dry ice canister has no risk of loosening or falling off during the entire lifting and lowering process, and achieving a dual improvement in safety and testing efficiency.

[0029] Working principle: The operator first places the dry ice can vertically on the support plate 41 of the positioning component 4, pulls the constraint strap 45 fixed to the other side of the extension rod 42 so that it passes through the double D buckle 44 and folds back, selects the corresponding sleeve hole position on the surface of the constraint strap 45 according to the diameter of the can, presses the female buckle 46, which is sleeved in the sleeve hole at the first end of the constraint strap 45, into the female buckle 47 in the sleeve hole at that position, forming a ring-shaped fixation for the dry ice can; starts the drive motor 22 of the lifting component 2 to drive the lead screw 23 fixedly connected to its output end to rotate, and through the meshing of the lead screw 23 and the threaded slider 24, the dry ice can is fixedly fixed. The combined transmission forces the slider 24 to rise and fall vertically along the inner wall of the slide groove 21 fixed to the top surface of the test platform 1. Since the side of the slider 24 is rigidly connected to the positioning component 4 through the connecting rod 3, the support plate 41 drives the fixed dry ice can to move synchronously to the test height. At this time, the constraint band 45 is kept taut under the anti-reverse locking action of the double D buckle 44. After the test, the reverse drive motor 22 resets the can, and the can can be disassembled by releasing the snap-fit ​​between the female buckle 46 and the female buckle 47. The position of the sleeve hole of the female buckle 46 on the constraint band 45 to snap-fit ​​the female buckle 47 can be changed to adapt to dry ice cans of different diameters.
