Technical Field

[0001] This utility model relates to the field of latex mattress testing technology, and in particular to a device for testing the elasticity of latex mattresses. Background Technology

[0002] In the sleep product market, latex mattresses have gained popularity among consumers due to their excellent elasticity, fit, and breathability. The elasticity of latex mattresses is a key indicator of their quality and comfort, directly affecting consumers' sleep experience. Therefore, accurate and reliable testing of latex mattress elasticity is of paramount importance for manufacturers to control product quality and for consumers to choose suitable products.

[0003] Because the test head is not replaceable, existing testing devices struggle to provide accurate and consistent test results when faced with latex mattresses of different characteristics. On one hand, the fixed shape and material of the test head may not be well adapted to the surface characteristics of various latex mattresses, resulting in uneven contact between the test head and the mattress surface, which in turn affects the accuracy of measurements of parameters such as sink depth and rebound speed. Utility Model Content

[0004] The technical problem to be solved by this invention is that the fixed shape and material of the test head in the existing technology may not be well adapted to the surface characteristics of various latex mattresses. Therefore, we propose a device for testing the elasticity of latex mattresses.

[0005] To achieve the above objectives, this application adopts the following technical solution: a device for testing the elasticity of a latex mattress, comprising a testing device body, a driving mechanism mounted on the top of the testing device body, a testing rod mounted on the bottom of the driving mechanism, an adjustment groove inside the testing rod, a rotating column rotatably connected inside the adjustment groove, a connecting rod inside the rotating column, a testing head fixedly connected to the bottom end of the connecting rod, insertion holes at both ends of the connecting rod, arc-shaped blocks fixedly connected to both ends of the adjustment groove, adjustment holes at both ends of the rotating column, a push block slidably connected inside the adjustment hole, and an insertion rod fixedly connected to the side of the push block near the inside of the adjustment hole.

[0006] Preferably, both ends of the adjustment hole are provided with sliding grooves, and both ends of the push block are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.

[0007] Preferably, a storage spring is fixedly connected to the side of the push block near the insertion rod, and the side of the storage spring away from the push block is fixedly connected to the inside of the adjustment hole.

[0008] Preferably, the adjusting groove has two annular grooves inside, and two annular blocks are fixedly connected to the outer diameter surface of the rotating column. The surface of the annular blocks is slidably connected to the inside of the annular grooves.

[0009] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is inserted into the interior of the insertion hole.

[0010] Preferably, both ends of the rotating column are provided with shrinkage grooves, and an insertion rod is slidably connected inside the shrinkage groove. A return spring is fixedly connected to the side of the insertion rod near the inside of the shrinkage groove, and the side of the return spring away from the insertion rod is fixedly connected to the inside of the shrinkage groove. Both ends of the test rod are provided with insertion holes.

[0011] Preferably, both sides of the shrinkage groove are fixedly connected to sliding grooves, and both ends of the insertion rod are fixedly connected to sliding blocks, with the surface of the sliding block slidably connected to the interior of the sliding groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a device for testing the elasticity of a latex mattress, comprising a testing device body 1, a driving mechanism 2 installed at the top of the testing device body 1, a testing rod 3 installed at the bottom of the driving mechanism 2, an adjustment groove 4 inside the testing rod 3, a rotating column 5 rotatably connected inside the adjustment groove 4, a connecting rod 6 inside the rotating column 5, a testing head 7 fixedly connected to the bottom end of the connecting rod 6, insertion holes 8 at both ends of the connecting rod 6, arc-shaped blocks 9 fixedly connected to both ends of the adjustment groove 4, and adjustment holes at both ends of the rotating column 5. Hole 10, with a push block 11 slidably connected inside the adjustment hole 10. A rod 12 is fixedly connected to the side of the push block 11 near the inside of the adjustment hole 10. The operator aligns the connecting rod 6 with the inside of the rotating column 5 and inserts the connecting rod 6 completely into the inside of the rotating column 5. At the same time, the operator rotates the rotating column 5, causing the rotating column 5 to move the push block 11 and gradually bring the push block 11 into contact with the arc block 9. The arc block 9 pushes the push block 11 and inserts the rod 12 into the inside of the insertion hole 8, thus fixing the test head 7, thereby achieving the function of installing and replacing the test head 7.

[0022] Reference Figure 4 As shown in this embodiment: both ends of the adjustment hole 10 are provided with sliding grooves 13, and both ends of the push block 11 are fixedly connected with sliders 14. The surface of the sliders 14 is slidably connected to the inside of the sliding grooves 13. When the operator moves the push block 11, the push block 11 drives the sliders 14 to slide inside the sliding grooves 13. Through the above settings, the movement of the push block 11 is more stable, avoiding the impact of shaking on the accuracy of the test results during the test.

[0023] Reference Figure 4As shown in this embodiment: a storage spring 15 is fixedly connected to the side of the push block 11 near the insertion rod 12, and the side of the storage spring 15 away from the push block 11 is fixedly connected to the inside of the adjustment hole 10. When the operator pushes the push block 11 to push the insertion rod 12, the insertion rod 12 compresses the storage spring 15 to store force, and drives the insertion rod 12 to be inserted into the insertion hole 8. When the operator releases the push block 11, the insertion rod 12 will be moved out of the insertion hole 8 under the action of the rebound force of the storage spring 15, so as to facilitate the operator to disassemble and replace the test head 7.

[0024] Reference Figure 4 and Figure 5 As shown in this embodiment: the adjustment groove 4 has two annular grooves 16 inside, and two annular blocks 17 are fixedly connected to the outer diameter surface of the rotating column 5. The surface of the annular blocks 17 is slidably connected to the inside of the annular grooves 16. When the operator rotates the rotating column 5 inside the adjustment groove 4, the rotating column 5 drives the annular blocks 17 to rotate inside the shrinkage groove 18. Through the above settings, the stability of the rotating column 5 rotating inside the adjustment groove 4 is effectively improved, and the shaking or deviation of the rotating column 5 during the rotation is avoided, thereby ensuring the accuracy and reliability of the latex mattress elasticity test.

[0025] Reference Figure 2 and Figure 4 As shown in this embodiment, the size of the insertion rod 12 is adapted to the size of the insertion hole 8, and the surface of the insertion rod 12 is inserted into the interior of the insertion hole 8. By adapting the size of the insertion rod 12 to the size of the insertion hole 8, the insertion rod 12 can be stably inserted into the interior of the insertion hole 8 and is not easy to fall out, which further improves the stability and reliability of the device.

[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: both ends of the rotating column 5 are provided with shrinkage grooves 18, and an insertion rod 20 is slidably connected inside the shrinkage groove 18. A return spring 19 is fixedly connected to the side of the insertion rod 20 near the inside of the shrinkage groove 18, and the side of the return spring 19 away from the insertion rod 20 is fixedly connected to the inside of the shrinkage groove 18. Both ends of the test rod 3 are provided with insertion holes 23. After the operator limits the insertion rod 12 to the insertion hole 8, the position of the shrinkage groove 18 is parallel to the insertion hole 23. At the same time, the return spring 19 is released and pushes the insertion rod 20 into the inside of the insertion hole 23, thereby locking the position of the rotating column 5 and preventing the rotating column 5 from rotating on its own.

[0027] Reference Figure 5As shown in this embodiment: both sides of the shrinkage groove 18 are fixedly connected to sliding grooves 21, and both ends of the insertion rod 20 are fixedly connected to sliding blocks 22. The surface of the sliding block 22 is slidably connected to the inside of the sliding groove 21. When the operator moves the insertion rod 20, the insertion rod 20 drives the sliding block 22 to slide inside the sliding groove 21. Through the above settings, the stability of the insertion rod 20 during the movement can be ensured, and its deviation or shaking can be avoided, thereby improving the detection accuracy.

[0028] Working principle: The operator aligns the connecting rod 6 with the inside of the rotating column 5 and inserts the connecting rod 6 completely into the rotating column 5. Simultaneously, the operator rotates the rotating column 5, causing the rotating column 5 to move the push block 11, which gradually contacts the arc-shaped block 9. The arc-shaped block 9 then pushes the push block 11, inserting the insertion rod 12 into the insertion hole 8, thus fixing the test head 7. This achieves the function of installing and replacing the test head 7. When the operator moves the push block 11, the push block 11 drives the slider 14 to move within the slide groove 13. The sliding motion, as described above, makes the movement of the push block 11 more stable, avoiding the impact of shaking on the accuracy of the test results during the testing process. When the operator pushes the push block 11 to push the insertion rod 12, the insertion rod 12 compresses the storage spring 15 to store force, and drives the insertion rod 12 into the insertion hole 8. When the operator releases the push block 11, the insertion rod 12 will move out of the insertion hole 8 under the action of the rebound force of the storage spring 15, thus facilitating the disassembly and replacement of the test head 7. When the operator rotates the rotating column 5 inside the adjustment groove 4, the rotating column 5 drives the annular block 17 to rotate inside the shrinkage groove 18. Through the above settings, the stability of the rotating column 5 rotating inside the adjustment groove 4 is effectively improved, avoiding shaking or deviation of the rotating column 5 during rotation, thereby ensuring the accuracy and reliability of the latex mattress elasticity test. The matching of the size of the insertion rod 12 with the size of the insertion hole 8 allows the insertion rod 12 to be stably inserted into the insertion hole 8, making it less likely to fall out, further improving the stability and reliability of the device. After the insertion rod 12 is positioned relative to the insertion hole 8, the position of the shrinkage groove 18 is parallel to the insertion hole 23. At the same time, the return spring 19 is released, pushing the insertion rod 20 into the insertion hole 23, thus locking the position of the rotating column 5 and preventing it from rotating. When the operator moves the insertion rod 20, the insertion rod 20 drives the sliding block 22 to slide inside the sliding groove 21. Through the above settings, the stability of the insertion rod 20 during movement can be ensured, preventing it from shifting or shaking, thereby improving the detection accuracy.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
