Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] An impact test device for testing the strength of building panels, such as Figure 1-5As shown, it includes a base 1, a hollow rod 2, a first sliding rod 3, a first connecting plate 4, a hollow cylinder 5, a locking mechanism 6 and a transfer mechanism 7. A hollow rod 2 is provided on the upper right side of the base 1 through a bolt. A sliding groove and eleven locking grooves are longitudinally opened on the right side of the hollow rod 2. The first sliding rod 3 is slidably connected to the inside of the hollow rod 2. The first sliding rod 3 can move up and down in the hollow rod 2. A through hole is opened in the middle and lower right side of the first sliding rod 3. A first connecting plate 4 is provided on the top of the first sliding rod 3. The first connecting plate 4 can move up and down with the first sliding rod 3. A hollow cylinder 5 is provided on the left side of the first connecting plate 4. During the test, a test ball can be dropped from the hollow cylinder 5. A through hole is opened at the lower right side of the hollow cylinder 5. A locking mechanism 6 with a locking effect on the first sliding rod 3 is connected to the inside of the first sliding rod 3. A transfer mechanism 7 for transferring building panels is slidably connected between the front and rear sides of the upper left side of the base 1.

[0036] like Figure 3 and Figure 6 As shown, the locking mechanism 6 includes a second slide bar 60, a locking plate 61, a first spring 62 and a handle 63. The second slide bar 60 is slidably connected to the through hole of the first slide bar 3. A locking plate 61 is provided on the right side of the second slide bar 60. The locking plate 61 is locked in the locking groove of the hollow rod 2 to limit the second slide bar 60 after the height is adjusted. A first spring 62 is provided between the left side of the second slide bar 60 and the first slide bar 3. The first spring 62 is wound around the second slide bar 60. The first spring 62 facilitates the locking of the locking plate 61. A handle 63 is provided on the right side of the locking plate 61. The handle 63 facilitates the movement of the second slide bar 60.

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8 As shown, the transfer mechanism 7 includes a first slider 70, a sliding frame 71, a support frame 72 and a first turn plate 73. The first sliders 70 are slidingly provided on the front and rear sides of the upper left side of the base 1. A sliding frame 71 is provided between the two first sliders 70. The sliding frame 71 can be moved left and right on the base 1 through the first slider 70. A support frame 72 is provided inside the sliding frame 71. A through hole is provided on the left side of the bottom of the sliding frame 71. The left side of the support frame 72 is rotatably connected to the first turn plate 73. The support frame 72 supports the first turn plate 73, and building panels can be placed on the first turn plate 73.

[0038] When conducting an impact test for testing the strength of a building board, first, the handle 63 is pulled out to the right so that the locking plate 61 moves to the right, thereby causing the second slide bar 60 to move to the right. At this time, the first spring 62 is compressed, and then the second slide bar 60 is driven to move in the slide groove of the hollow rod 2 by moving the handle 63. The locking plate 61 moves along with the second slide bar 60, so that the height of the first slide bar 3 can be adjusted. When the first slide bar 3 is adjusted to the required height, the handle 63 is released. Under the action of the first spring 62, the second slide bar 60 and the locking plate 61 both move to the left and reset. At this time, the locking plate 61 is stuck in the locking groove at a relative height to the hollow rod 2, so that the first slide bar 3 can be adjusted. The height of the rod 3 is limited; then the building board is placed on the first rotating plate 73, and under the action of the first slider 70, the sliding frame 71 is moved to the right. The sliding frame 71 moves to the right, causing the support frame 72, the first rotating plate 73 and the building boards on the first rotating plate 73 to move to the right, until the building boards are moved to the bottom of the hollow cylinder 5; then the test ball is thrown downward through the hollow cylinder 5, and the test ball falls downward on the building boards below, thereby completing the impact test of the building board strength test; when the impact test is completed, the sliding frame 71 is pulled to the left to reset, thereby causing the support frame 72, the first rotating plate 73 and the building boards on the first rotating plate 73 to move to the left to reset.

[0039] Example 2

[0040] On the basis of Example 1, Figure 1 、 Figure 2 、 Figure 3 and Figure 9 As shown, it also includes a clamping mechanism 8 for clamping the building board. The clamping mechanism 8 includes a third slide bar 80, a clamping block 81 and a second spring 82. The third slide bar 80 is slidably connected to the upper right side of the first rotating plate 73. The third slide bar 80 can move. A clamping block 81 is provided on the upper part of the third slide bar 80. The clamping block 81 can clamp the building board. Two second springs 82 are connected between the lower part of the third slide bar 80 and the first rotating plate 73. The second springs 82 are all wound on the third slide bar 80, and the second springs 82 can be extended and retracted.

[0041] Before placing the building board on the first rotating plate 73, pull the clamp block 81 upward, and the clamp block 81 moves upward, causing the third slide bar 80 to move upward. At this time, the second spring 82 is compressed, and the building board is placed on the first rotating plate 73. Release the clamp block 81, and the clamp block 81 and the third slide bar 80 both move downward. At this time, the clamp block 81 clamps the building board to prevent the building board from shifting; when the impact test is completed, pull the clamp block 81 upward, causing the third slide bar 80 to move upward, and then remove the building board from the first rotating plate 73, and then release the clamp block 81. Under the action of the second spring 82, the clamp block 81 and the third slide bar 80 both move downward and reset.

[0042] like Figure 1 、 Figure 2 、 Figure 3 and Figure 10 As shown, a protective mechanism 9 is also included to prevent debris from flying around. The protective mechanism 9 includes a fixed block 90, a second rotating plate 91, a spiral groove rod 92 and a fixed rod 93. Two fixed blocks 90 are provided on the upper parts of the front and rear sides of the right part of the base 1. The second rotating plate 91 is rotatably connected between the fixed blocks 90 on the same side laterally. The fixed block 90 can fix the second rotating plate 91. A spiral groove rod 92 is provided in the middle of the second rotating plate 91. A fixed rod 93 is provided on the right parts of the front and rear sides of the sliding frame 71. The fixed rod 93 moves with the sliding frame 71. When the fixed rod 93 moves to the right into the spiral groove on the spiral groove rod 92, the second rotating plate 91 can be slowly erected. At this time, the second rotating plate 91 has a protective effect, which can prevent the flying plate debris during the test from causing harm to people.

[0043] When the sliding frame 71 moves to the right, the fixed rod 93 can be moved to the right. When the fixed rod 93 slowly moves to the right in the spiral groove on the spiral groove rod 92, the spiral groove rod 92 can be rotated, thereby causing the second rotating plate 91 to slowly rotate upward until the second rotating plate 91 is in an upright state. At this time, the second rotating plate 91 can block the debris generated during the impact test to prevent the flying debris from affecting people's safety; after the impact test is completed, the sliding frame 71 is moved to the left and reset. The sliding frame 71 is moved to the left and reset, causing the fixed rod 93 to move to the left and reset. When the fixed rod 93 moves to the left out of the spiral groove on the spiral groove rod 92, the second rotating plate 91 will rotate downward and reset.

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 11 and Figure 12As shown, it also includes a dumping mechanism 10 for assisting the first rotating plate 73 to dump, the dumping mechanism 10 includes a guide rail 102, a second slider 103, a connecting rod 104, a connecting block 105 and a rotating block 106, a support plate 101 is provided on the left side of the middle of the base 1, and a guide rail 102 is provided on the right side of the upper part of the support plate 101, the support plate 101 has a supporting effect on the guide rail 102, the guide rail 102 is slidably connected to the inside of the guide rail 102, and the guide rail 102 has a guiding effect on the second slider 103. A connecting rod 104 is provided on the upper part of the slider 103, and the connecting rod 104 passes through the through hole at the bottom of the sliding frame 71 from bottom to top. The movement of the connecting rod 104 can enable the second slider 103 to move in the guide rail 102. A connecting block 105 is provided on the upper part of the connecting rod 104, and a rotating block 106 is rotatably connected to the connecting block 105. The rotating block 106 rests on the first rotating plate 73 and supports the first rotating plate 73. When the connecting rod 104 moves to the right with the sliding frame 71, the first rotating plate 73 can be leveled.

[0045] The angle at which the first rotating plate 73 is supported by the rotating block 106, the connecting block 105 and the connecting rod 104 is convenient for people to place building panels. When the sliding frame 71 drives the supporting frame 72 to move to the right, under the action of the second slider 103 and the guide rail 102, the connecting rod 104 can move to the right and downward at the same time, so that the connecting block 105 and the rotating block 106 can also move to the lower right. The rotating block 106 rotates clockwise when it moves downward. When the second slider 103 moves to the right to the bottom of the guide rail 102, the connecting rod 104 is 104, the connecting block 105 and the rotating block 106 no longer support the first rotating plate 73 and the building board. At this time, the building board is in a state of being placed flat on the support frame 72 and can wait for the impact test; after the impact test is completed, the sliding frame 71 moves to the left and resets. Under the action of the second slider 103 and the guide rail 102, the connecting rod 104, the connecting block 105 and the rotating block 106 all move to the upper left and reset. The rotating block 106, the connecting block 105 and the connecting rod 104 support the first rotating plate 73 again, which makes it convenient for people to take out the building board.

[0046] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 13 、 Figure 14 and Figure 15As shown, it also includes an unlocking mechanism 11, which includes a fourth slide bar 111, a third spring 112, a second connecting plate 113, a hollow plate 114, a fifth slide bar 115, a short rod 116 and a guide sleeve 117. The left side of the right side of the base 1 is slidably connected to the fourth slide bar 111, and the front and rear sides of the right side of the fourth slide bar 111 are connected to the right side of the base 1. The third spring 112 can be retracted, and the front and rear sides of the right side of the fourth slide bar 111 are connected to the second connecting plate 113. The upper part of the second connecting plate 113 is provided with a hollow plate 114.

A short rod 116 is provided on the left portion of the fifth slide bar 115 and passes through the through hole on the right side of the hollow cylinder 5. Before the experiment, the short rod 116 can lock the test ball and unlock the test ball when the short rod 116 moves to the right. Guide sleeves 117 are connected to the upper portions of the front and rear sides of the first slide bar 3. The fifth slide bar 115 is slidably connected to the guide sleeves 117. The guide sleeves 117 guide the fifth slide bar 115, allowing the fifth slide bar 115 to move up and down along with the first slide bar 3.

[0047] When the first slide bar 3 is moved to adjust the height, due to the action of the guide sleeve 117, the fifth slide bar 115 will move accordingly in the hollow plate 114. When the second slide bar 103 and the connecting rod 104 move to the right to the bottom of the guide rail 102, the second slide bar 103 will push the fourth slide bar 111 to move to the right. The fourth slide bar 111 moves to the right, causing the second connecting plate 113 to move to the right. The second connecting plate 113 moves to the right, causing the hollow plate 114 to move to the right. The hollow plates 114 all move to the right, causing the fifth slide bar 115 to move to the right. The fifth slide bar 115 moves to the right, causing the short rod 116 to move to the right. At this time, The test ball changes from a locked state to an unlocked state, so that an impact test can be carried out. At this time, the third spring 112 is in a compressed state. When the second slider 103 and the connecting rod 104 move to the left and leave the fourth slider 111, under the action of the third spring 112, the fourth slider 111 moves to the left and resets, so that the second connecting plate 113, the hollow plate 114, the fifth slider 115 and the short rod 116 all move to the left and reset, and the short rod 116 is re-engaged in the through hole on the right side of the hollow cylinder 5. The short rod 116 can block the next test ball. Repeating the above operation can achieve the effect of automatically releasing the test ball, thereby improving the test efficiency.
