[0029] To facilitate the understanding of this embodiment, a jig for measuring the water absorption thickness swelling rate of a board disclosed in the embodiments of the present utility model will be introduced in detail first.

[0030] Embodiment:

[0031] As Figures 1-4 , a jig for measuring the water absorption thickness swelling rate of a board according to the present application includes a measuring jig body 100. The measuring jig body 100 has a specimen inlet 107 and a receiving cavity 108 communicating with the specimen inlet 107. Six side plate bolt holes 1032 are provided in the first side plate 103 and the second side plate 104 of the measuring jig body 100 along the length direction, and an isolation bolt 1033 is threadedly connected to each of the side plate bolt holes 1032; wherein the side plate bolt holes 1032 are arranged at uneven intervals. Since the receiving cavity 108 of the measuring jig body 100 is separated into multiple specimen receiving spaces by the isolation bolts 1033 arranged at uneven intervals, each specimen receiving space can accommodate a specimen, so as to be applicable to specimens of different thicknesses, with good flexibility in use, wide application range, and high working efficiency.

[0032] During the test, the specimen enters the receiving cavity 108 from the specimen inlet 107, and then the specimen is moved in a direction away from the specimen inlet 107, and the isolation bolt 1033 is rotated to separate the previous specimen from the next specimen; different thickness specimens are placed in the receiving cavity 108 in sequence according to the above steps, and finally the present application containing specimens of different thicknesses is placed in a constant temperature distilled water tank, and the experiment of the water absorption thickness swelling rate of the board can be completed.

[0033] Specifically, the measuring fixture body 100 includes a top plate 101, a bottom plate 102, a first side plate 103, a second side plate 104, a first end plate 105 and a second end plate 106. A first long hole 1011 is provided on the top plate 101 along the length direction, a second long hole (not shown in the figure) is provided on the bottom plate 102 along the length direction, a third long hole 1031 is provided on the first side plate 103 along the length direction, and a fourth long hole (not shown in the figure) is provided on the second side plate 104 along the length direction. The first long hole 1011, the second long hole, the third long hole 1031 and the fourth long hole are used for water inlet during testing, so that water can quickly fill the entire accommodating cavity 108, making the starting time of all specimen tests consistent and improving the accuracy of the test effect. The specimen inlet 107 is provided on the top plate 101 near the first end plate 105 along the width direction, facilitating the specimen to enter the accommodating cavity 108 from one direction.

[0034] As a preferred embodiment of this embodiment, a support plate 1012 is provided above the measuring fixture body 100 near the specimen inlet 107. A support plate bolt hole 1013 is provided on the support plate 1012, and a limit bolt 1014 is threadedly connected in the support plate bolt hole 1013. Through the above structural design, when the last specimen is loaded, the limit bolt 1014 is rotated to limit the last specimen and prevent the last specimen from moving laterally.

[0035] Specifically, six side plate bolt holes 1032 are provided at the lower parts of the first side plate 103 and the second side plate 104. The interval width between these side plate bolt holes 1032 increases sequentially from the side near the specimen inlet 107 to the side far from the specimen inlet 107. That is, during testing, it is preferred to load the thickest specimen first, and then load specimens with gradually decreasing thickness in sequence.

[0036] As a preferred embodiment of this embodiment, a slideway 1034 is provided on the upper parts of the first side plate 103 and the second side plate 104 along the length direction. A slider 1035 is slidably installed in the slideway 1034. Specifically, the slideway 1034 is T-shaped. The slider 1035 includes a slider body, a connecting member provided on the slider body and adapted to the slideway, and a slider bar provided on the slider body for pushing the specimen. After the specimen enters the accommodating cavity 108 from the specimen inlet 107, an external force is applied to the slider 1035. The connecting member of the slider 1035 moves along the slideway 1034, and the slider bar of the slider 1035 pushes the specimen to move in the direction away from the specimen inlet 107. After the specimen is pushed in place, the slider 1035 resets to push the next specimen.

[0037] As a preferred embodiment of the present embodiment, a first rubber pad 1015 is provided on the inner wall of the top plate 101, a second rubber pad 1021 is provided on the inner wall of the bottom plate 102, a third rubber pad 1036 is provided on the inner wall of the first side plate 103, a fourth rubber pad 1041 is provided on the inner wall of the second side plate 104, and a fifth rubber pad 1061 is provided on the inner wall of the second end plate 106. By providing the first rubber pad 1015, the second rubber pad 1021, the third rubber pad 1036, the fourth rubber pad 1041, and the fifth rubber pad 1061 on the inner walls of the top plate 101, the bottom plate 102, the first side plate 103, the second side plate 104, and the second end plate 106 respectively, the specimen is separated from the measuring jig body 100, playing a buffering role to prevent the specimen from directly contacting and colliding with the measuring jig body 100, causing damage or breakage of the specimen and affecting the test accuracy and test effect.

[0038] As a preferred embodiment of the present embodiment, both the limit bolt 1014 and the isolation bolt 1033 are butterfly bolts, which are convenient for users to apply torque to the butterfly bolts.
