Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, and in particular to an impact test chamber for pressure impact testing. Background Technology

[0002] The resilience of a pillow determines its comfort and durability. Consumers test the resilience of a pillow by pressing it with their hands when purchasing it, while in factories, the resilience of a pillow is tested using a pressure impact test chamber.

[0003] In existing pressure impact tests for verifying pillow resilience, a pressure mechanism at the top applies pressure to a pillow placed directly beneath it. The pillow's resilience is judged by observing its rebound effect after being impacted. However, the pressure from the pressure mechanism at the top of such instruments is a fixed pressure, which cannot accurately determine the quality of the pillow's resilience. Furthermore, the platform on which the pillow is placed does not provide any restraint. If the center of the pillow is not placed directly beneath the pressure mechanism when the pillow is placed, the pillow can easily shift or even fly off the platform due to the pressure from the mechanism.

[0004] Currently, the technical problems of the pressure mechanism in the aforementioned impact test chamber being a fixed pressure, making it impossible to more accurately determine the quality of the pillow's resilience, and the platform on which the pillow is placed not providing any restraint for the pillow, have not yet been properly resolved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an impact test chamber for pressure impact testing, so as to solve the technical problems that the pressure mechanism in the existing impact test chamber is a fixed pressure, which cannot more accurately determine the quality of pillow resilience, and the platform for placing the pillow does not have any limiting effect on the pillow.

[0043] Example

[0044] like Figures 1-5 As shown, this utility model discloses an impact test chamber for pressure impact testing, comprising a chamber body 1, an electric push rod 2, a pressure adjustment component 3, a placement platform 4, and a limiting component 5. The electric push rod 2 is installed above the chamber body 1, and its movable end moves up and down inside the chamber body 1; the pressure adjustment component 3 is fixed to the bottom of the movable end of the electric push rod 2; the placement platform 4 is installed below the chamber body 1; and the limiting component 5 is installed on the placement platform 4 to limit the movement of objects on the placement platform 4.

[0045] Specifically, the pillow is placed on the placement platform 4, the limiting component 5 limits both ends of the pillow, the pressure adjustment component 3 is located directly above the pillow, and the movable end of the electric push rod 2 drives the pressure adjustment component 3 to move downward to conduct a pressure impact test on the pillow to verify the pillow's resilience. By adjusting the pressure of the pressure adjustment component 3, the quality of the pillow's resilience can be more accurately determined, while the limiting component 5 limits the pillow to prevent it from shifting due to pressure.

[0046] As some embodiments, the pressure adjustment assembly 3 includes a connector 310, a carrier 320, and pressure blocks 330. The top of the connector 310 is fixed to the bottom of the movable end of the electric push rod 2; the top of the carrier 320 is threadedly connected to the bottom of the connector 310; and there are 1 to 4 pressure blocks 330, which are placed inside the carrier 320.

[0047] The threaded connection allows for easy replacement of the number of pressure blocks 330. Increasing the number of pressure blocks 330 increases the pressure on the pillow. Under greater pressure, the pillow's rebound effect and speed determine the quality of its resilience.

[0048] Furthermore, the connector 310 is in the shape of a round rod, and a threaded hole 311 is provided on the inner side of the bottom of the connector 310; the bearing member 320 includes a bearing plate 321 and a threaded rod 322. The bearing plate 321 has a circular cross-section, the bottom of the threaded rod 322 is fixed to the center of the bearing plate 321, and the upper part of the threaded rod 322 is threadedly connected to the connector 310; the pressure block 330 is in the shape of a ring, and the center of the pressure block 330 passes through the threaded rod 322 and is placed inside the bearing plate 321.

[0049] As one embodiment, the placement platform 4 consists of several crossbars 410, which are installed in parallel below the box body 1, with the ends of the crossbars 410 fixed to the sides of the box body 1.

[0050] The bottom of the pillow contacts the top of the crossbar 410.

[0051] Furthermore, the limiting assembly 5 includes a limiting member 510 and a spring 520. The limiting member 510 passes through the crossbar 410, and there are two limiting members 510, which are placed symmetrically. One end of the spring 520 is connected to the limiting member 510, and the other end is connected to the side of the housing 1. The spring 520 is sleeved on the crossbar 410, and the number of springs 520 is twice that of the crossbar 410.

[0052] In one embodiment, there are 5 crossbars 410 and 10 springs 520.

[0053] Among them, the elasticity of spring 520 effectively ensures that pillows of different lengths can be effectively limited.

[0054] Furthermore, the limiting member 510 includes a limiting plate 511 and two limiting blocks 512. The limiting plate 511 passes through the crossbar 410 and is connected to one end of the spring 520; the two limiting blocks 512 are symmetrically fixed on both sides of the limiting plate 511.

[0055] Among them, the limiting plate 511 limits the left and right ends of the pillow, and the limiting block 512 limits the front and back ends of the pillow.

[0056] The operating principle of this embodiment is as follows:

[0057] The pillow is placed on the horizontal bar 410. The limiting plate 511 and the limiting block 512 limit the end of the pillow. The movable end of the electric push rod 2 drives the pressure adjustment component 3 to move downward to conduct a pressure impact test on the pillow to verify the pillow's resilience. The pressure is adjusted by changing the number of pressure blocks 330, which allows for a more accurate determination of the pillow's resilience.

[0058] The advantages of this embodiment are: by setting a pressure adjustment component, the quality of the pillow's resilience can be determined more accurately; by setting a limiting component, the pillow can be prevented from shifting due to pressure.

[0059] The embodiments described herein are preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Furthermore, the above embodiments can be combined with each other for use. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
