Description

TECHNICAL FIELD

[0001] The utility model relates to the field of container detection technology, and specifically belongs to a kind of heat preservation container impact resistance testing device. BACKGROUND

[0002] The impact resistance of the vacuum cup refers to its ability to maintain structural integrity and normal function when subjected to external impact. In daily use, the vacuum cup is inevitably subjected to bumps, drops and other situations. If the impact resistance of the vacuum cup is poor, it may cause the cup body to break, deform, and even affect its heat preservation function. Good impact resistance can prevent the vacuum cup from breaking when impacted, avoiding injury from fragments, especially for children using the vacuum cup, which is particularly important. The vacuum cup with good impact resistance can still maintain good heat preservation effect after being impacted, without affecting the integrity of the heat preservation layer due to cup body damage. The national standard GB 29606-2013 "Stainless Steel Vacuum Cup", GB / T 40355-2021 "Stainless Steel Vacuum Heat Preservation Container" and industry standard QB / T 5162-2021 "Titanium Cup" all have testing requirements for the impact resistance of the vacuum container. However, the method in the standard is to hang the rope and cut it off, and the sample falls freely. This results in different positions and states of the vacuum cup during each test, leading to large differences in test results each time. SUMMARY

[0027] like Figures 1-6 As shown, the impact resistance testing device for thermal insulation containers of this utility model includes a lifting base 1 with a base plate 11 and a top plate 12. A lifting device is installed on the lifting base 1. The lifting device includes two corresponding lead screws 3. The lead screws 3 are installed on the base plate 11 and the top plate 12 through a first bearing 31 and a second bearing 32. A drive motor 2 is also installed on the base plate 11 between the two lead screws 3. A first gear 21 is installed on the shaft of the drive motor 2. A second gear 33 corresponding to the first gear 21 is installed on each of the two lead screws 3. The second gear 33 and the first gear 21 are connected by a chain 34. A bearing plate 7 is installed on the two lead screws 3. The bearing plate 7 is located above the top plate 12 and is rotatably connected to the two lead screws 3 by threads. When the drive motor 2 drives the two lead screws 3 to rotate through the chain 34, the bearing plate 7 can move up and down.

[0028] A sliding rod 8, parallel to the lead screw 3, is fixedly installed on the top plate 12. The sliding rod 8 passes through the support plate 7, and the sliding rod 8 and the support plate 7 are slidably connected by a linear bearing 81. The sliding rod 8 guides the up-and-down movement of the support plate 7, preventing the support plate 7 from tilting or leaning. There are two sliding rods 8, and the surface of the sliding rod 8 is marked with scale values. The scale values ​​facilitate the positioning of the distance between the support plate 7 and the top plate 12, realizing the determination of the impact distance between the impact block and the sample to be tested, and enabling the device to achieve test repeatability.

[0029] A release device is installed on the support plate 7. The release device includes a push rod motor 72, and the push rod 73 of the push rod motor 72 is configured to cooperate with the through hole 71. A clamping device is also installed on the top plate 12. The support plate 7 has through holes 71 corresponding to the release device and the clamping device. An impact body is hung on the push rod 73 by a rope loop 91. The impact body and the rope loop 91 constitute an impact block. The rope loop 91 passes through the support plate 7 so that the impact body can be suspended directly above the clamping device. The impact body includes a support plate 92 and a threaded rod 9 installed on the support plate 92. A nut 93 is provided on the threaded rod 9. The rope loop 91 is connected to the top of the threaded rod 9. A weight 94 is installed on the threaded rod 9 between the nut 93 and the support plate 92.

[0030] The clamping device includes a mounting plate 4 vertically mounted on a top plate 12. Two corresponding sliding plates 52 are mounted on the front side of the mounting plate 4 via two vertically arranged slide rails 41. A clamping motor 5 is also mounted on the mounting plate 4 to the right of the slide rails 41. A double-ended screw 51 is mounted on the shaft of the clamping motor 5. The two sliding plates 52 are respectively located at both ends of the double-ended screw 51, and the sliding plates 52 are rotatably connected to the double-ended screw 51 via threads. The sliding plates 52 have mounting holes, and a shaft 6 is rotatably mounted within these holes. A limit clamp 61 is mounted on the shaft 6. The limit clamps 61 mounted on the two sliding plates 52 are correspondingly positioned, causing the clamping motor 5 to drive the double-ended screw 51 to rotate. When the two sliding plates 52 are close together, the limiting clamp 61 can clamp the insulation container placed between the two limiting clamps 61. The inner surface of the limiting clamp 61 is also provided with a rubber layer 64 to prevent damage to the outer surface of the insulation container during clamping. The inner wall of the mounting hole is also provided with several slots 53, and the shaft 6 is provided with a sliding groove 62 corresponding to the slots 53. The sliding groove 62 is equipped with a limiting strip 63 that cooperates with the slots 53. When using the limiting clamp 61 to clamp the insulation container, the rotation angle of the limiting clamp 61 can be adjusted by adjusting the sliding groove 62 and its corresponding slot 53, so as to fix the angle of the limiting clamp 61, that is, adjust the impact angle of the insulation container.

[0031] The drive motor 2 and clamping motor 5 of the thermal insulation container impact resistance test device both use servo motors and are electrically connected to an external power supply. The push rod 73 of the push rod motor 72 can freely extend and retract under the control of the external power supply. When the push rod 73 retracts, the rope loop 91 disengages from the push rod 73, and the impactor impacts the thermal insulation container in a free-fall manner.

[0032] When using this impact resistance testing device for thermal insulation containers, the height of the support plate 7 is first controlled by the drive motor 2. Then, the rotation angle of the limiting clamp 61 is adjusted by the limiting strip 63, the sliding groove 62, and the slot 53. Next, the thermal insulation container is placed between the two limiting clamps 61, and the clamping motor 5 clamps the container tightly. After clamping, the push rod motor 72 is powered to extend the top rod 73. The rope loop 91 of the impact block with the weights 94 adjusted in quantity is passed through the through hole 71 and hung on the top rod 73. The test can then begin. During the test, the push rod motor 72 is controlled to retract the top rod 73, the rope loop 91 falls off, and the impact body impacts the thermal insulation container in a free-fall manner. After the test, the clamping motor 5 is controlled to release the limiting clamps 61 from the thermal insulation container, and the impact resistance testing device can be readjusted for the next test.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
