Description

Technical Field

[0001] This utility model relates to the technical field of mattress testing devices, and more specifically to a mattress spring core durability testing device. Background Technology

[0002] Mattresses primarily provide support and comfort during sleep to protect the user's spine and optimize sleep quality. Mattresses can be divided into a support layer, a comfort layer, and a fabric layer. The support layer is the skeleton of the mattress, often composed of a cuboid frame made of various springs. Soft materials and fabrics are then distributed on the skeleton to achieve support, comfort, and durability.

[0003] The spring core in a mattress is part of the support layer. The durability and elastic support of the spring core reflect the overall performance of the mattress. Due to the different weights of users, the impact pressure that the mattress will withstand during use will also be different. If the elastic rebound force of the spring core is insufficient, it is easy for the spring core to deform under repeated pressure, affecting the support of the mattress. Therefore, a mattress spring core testing device is needed to reflect the service life and rated pressure that the mattress spring core can withstand. Utility Model Content

[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0031] like Figure 1-4 As shown, a mattress spring core durability testing device includes a mattress body 5, and further includes:

[0032] The base frame 1 and the mattress body 5 are fixed to the base frame 1;

[0033] Support frame 3 is mounted on base frame 1;

[0034] Pressing unit 4 is mounted on support frame 3 and includes bending plate 41 and adjusting plate 42 mounted on bending plate 41. A second motor 47 is mounted on adjusting plate 42 and a turntable 43 is attached to the output end of the second motor 47. A drive rod 45 is mounted at the eccentric part of turntable 43.

[0035] The adjustment plate 42 is slidably provided with a reciprocating push block 44 that cooperates with the drive rod 45, and one end of the reciprocating push block 44 is provided with a pressure plate 46 facing the mattress body 5.

[0036] Specifically, the base frame 1 is used to support the parts required during the testing process, such as... Figure 1As shown, the support frame 3 can move on the base frame 1, and the position of the pressing unit 4 in the longitudinal direction on the base frame 1 can be adjusted. The first motor 31 can drive the pressing unit 4 to move on the support frame 3, and the position of the pressing unit 4 in the transverse direction on the base frame 1 can be adjusted. This allows the mattress body 5 to be tested at different positions, improving the accuracy of the testing process. When testing the mattress body 5, the mattress body 5 is fixed to the base frame 1, and then the pressing unit 4 is moved on the support frame 3, causing the pressure plate 46 to move directly above the mattress. The second motor 47 runs to drive the turntable 43 to rotate, and the drive rod 45 rotates on the turntable 43 to drive the reciprocating push block 44 to slide up and down on the adjustment plate 42. The pressure plate 46 intermittently presses the mattress body 5 until the surface of the mattress body 5 deforms, thereby determining the durability and service life of the mattress spring core.

[0037] As a further embodiment of this utility model, the turntable 43 has eccentric holes 431 arranged in a linear array. The drive rod 45 is engaged with the eccentric holes 431. The turntable 43 rotates on the adjusting plate 42. The reciprocating push block 44 has a groove 441. The drive rod 45 slides in the groove 441. Multiple eccentric holes 431 can be opened on the turntable 43. The closer the eccentric hole 431 is to the central axis of the turntable 43, the higher the sliding frequency of the reciprocating push block 44 after the drive rod 45 is installed. Conversely, the farther the eccentric hole 431 is from the central axis, the lower the sliding frequency of the reciprocating push block 44. The groove 441 on the reciprocating push block 44 cooperates with the drive rod 45. At this time, the rotation of the turntable 43 drives the reciprocating push block 44 through the cooperation of the drive rod 45 and the groove 441, so that the reciprocating push block 44 slides on the adjusting plate 42.

[0038] Furthermore, an adjusting rod 48 is threaded onto the bending plate 41. The end of the adjusting rod 48 engages with the adjusting plate 42. When the adjusting rod 48 is rotated, the adjusting plate 42 slides on the bending plate 41, thereby adjusting the distance between the pressure plate 46 and the mattress body 5, and thus adjusting the pressure applied by the pressure plate 46 to the bed frame.

[0039] As a further embodiment of this utility model, the adjustment plate 42 is provided with a slide rail 421, and the reciprocating push block 44 slides on the slide rail 421. The slide rail 421 improves the smoothness of the sliding of the reciprocating push block 44, and at the same time limits the direction of the reciprocating push block 44, so that the reciprocating push block 44 can only slide along the slide rail 421, so that the pressure plate 46 presses the mattress body 5 back and forth.

[0040] As a further embodiment of this utility model, a circular groove is provided on the pressure plate 46, and a sliding plate 463 is slidably disposed in the circular groove. A spring 462 is disposed between the sliding plate 463 and the pressure plate 46. A gauge 461 is disposed on the pressure plate 46. The output end of the gauge 461 passes through the circular groove and abuts against the sliding plate 463. The gauge 461 can be a pressure gauge 461. When the mattress body 5 is tested, the pressure plate 46 reciprocates to press the mattress body 5. At this time, the sliding plate 463 pre-contacts the mattress and slides upward to squeeze the output end of the gauge 461. The spring 462 is compressed and in a contracted state. A certain pressure is generated in the gauge 461. When the surface of the mattress body 5 is deformed, that is, the spring core is deformed, so that the elastic force of the spring core is reduced. At this time, the pressure of the gauge 461 will change, thereby stopping the pressing unit 4 from operating. The number of times the reciprocating push block 44 is pressed down is recorded by the technical gauge, and the time is calculated by the number of times, thereby obtaining the durability of the spring core.

[0041] As a further embodiment of this utility model, a first motor 31 is provided on the support frame 3, and a screw 32 is provided at the output end of the first motor 31. A transmission block 411 that is threadedly engaged with the screw 32 is provided on the bending plate 41. The first motor 31 and the second motor 47 are both of the model number: MHMF042L1U4-1116. The first motor 31 controls the screw 32 to rotate, and under the action of the rotation of the screw 32, the transmission block 411 moves in conjunction with the bending plate 41 to move, so that the bending plate 41 slides along the support frame 3, thereby adjusting the position of the pressing unit 4.

[0042] As a further embodiment of this utility model, the base frame 1 includes a square frame 11 and a support plate 12 disposed on the square frame 11. The support plate 12 is provided with a first limiting plate 2 and a second limiting plate 6 that abut against the mattress body 5. The first limiting plate 2 is fixed to the corner of the support plate 12 by bolts. When the mattress body 5 is tested, the mattress body 5 is attached to the first limiting plate 2, and then the second limiting plate 6 is attached to the mattress body 5 through the positioning hole 122, thereby fixing the mattress body 5 to its own base frame 1 to avoid the mattress body 5 from shaking during the test.

[0043] As a further embodiment of this utility model, the support plate 12 is provided with mounting holes 121 and positioning holes 122 respectively. The support plate 12 is fixed to the frame 11 by bolts passing through the mounting holes 121. The first limiting plate 2 and the second limiting plate 6 clamp and fix the mattress body 5 through the positioning holes 122. The mounting holes 121 are used to fix the support plate 12 to the frame 11, while the positioning holes 122 can adjust the position of the second limiting plate 6 to adapt to the detection of mattress bodies 5 of different sizes, thereby improving the applicability of the detection device.

[0044] As a further embodiment of this utility model, a notch 21 is provided on the first limiting plate 2. When multiple tests are performed on mattresses of the same size, it is not necessary to remove the first limiting plate 2 and the second limiting plate 6. One corner of the mattress can be removed through the notch 21, and then the entire mattress can be removed to replace the mattresses in the same batch.

[0045] As a further embodiment of this utility model, a locking member 33 is provided on the support frame 3. The locking member 33 cooperates with the base frame 1. The locking member 33 can be a bolt or a threaded knob. When the position of the support frame 3 on the frame 11 is determined, the locking member 33 can be rotated to fix the support frame 3.

[0046] As a further embodiment of this utility model, the base frame 1 is provided with feet, which are located at the four corners of the frame 11 to support the base frame 1 and thereby improve the stability of the base frame 1 during the testing process.

[0047] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
