[0002] With the development of material science, fiberglass board (abbreviated as fiberglass board) as a high-performance composite material has been widely used in many fields such as construction, transportation, electronics, etc. due to its light weight, high strength, corrosion resistance and other characteristics.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0023] Example 1: Figure 1-Figure 4 As shown, a glass fiber board compressive strength detection device includes a frame 100, a detection mechanism 110, a gravity mechanism 200 and a clamping drive mechanism 300.

[0024] A slide groove 101 is provided on the inner bottom surface of the frame 100 ; a detection mechanism 110 is installed on the frame 100 , and the detection mechanism 110 is used to detect the bending degree of the fiberglass board.

[0025] The gravity mechanism 200 includes a wire roller 201, a connecting wire 202 and a pressing plate assembly. The connecting wire 202 is wound around the wire roller 201; the pressing plate assembly is connected to one end of the connecting wire 202, and the pressing plate assembly is used to press the fiberglass board.

[0026] The clamping drive mechanism 300 is used to clamp the glass fiber board. The clamping drive mechanism 300 is used to drive the line roller 201 to rotate, so that the pressure plate assembly moves upward or downward.

[0027] Specifically, when the fiberglass board to be tested is placed on the clamping drive mechanism 300, the fiberglass board is clamped by the clamping drive mechanism 300, and at the same time, the clamping drive mechanism 300 also drives the line roller 201 to rotate, so that the connecting line 202 and the pressure plate assembly move downward, and then the pressure plate assembly is pressed on the fiberglass board, so that the connecting line 202 is in a relaxed state. At this time, if the bending degree of the fiberglass board exceeds the preset value, it means that the compressive strength of the fiberglass board is unqualified; if the bending degree of the fiberglass board does not exceed the preset value, it means that the compressive strength of the fiberglass board is qualified.

[0028] like Figure 1 and Figure 2 As shown, the detection mechanism 110 includes a push switch 111 and a warning light 112. The push switch 111 is installed on the inner bottom surface of the frame 100, and the push switch 111 is located directly below the wire roller 201; The warning light 112 is installed on the frame 100 , and the pressing switch 111 is used to control the start and stop of the warning light 112 .

[0029] Specifically, when the fiberglass board is placed on the clamping drive mechanism 300, the fiberglass board is located directly above the push switch 111. During the test, when the fiberglass board is deformed and squeezes the push switch 111, it indicates that the deformation of the fiberglass board exceeds the preset value, indicating that the compressive strength test of the fiberglass board is unqualified.

[0030] During the test, when the fiberglass board does not press the push switch 111, it indicates that the deformation of the fiberglass board exceeds the preset value, which means that the compressive strength test of the fiberglass board is qualified.

[0031] When the glass fiber board presses the push switch 111 , the warning light 112 emits a flashing light.

[0032] The preset value mentioned above refers to the distance between the push switch 111 and the bottom of the glass fiber board.

[0033] like Figure 4 As shown, the pressure plate assembly includes a hook 203, a support plate 204, a vertical rod 205 and four weight rings 206. The hook 203 is fixedly connected to one end of the connecting line 202; the vertical rod 205 is installed on the top surface of the support plate 204, and the vertical rod 205 is plugged into the hook 203; the four weight rings 206 are placed on the support plate 204, and the center holes of the four weight rings 206 are all sleeved on the vertical rod 205.

[0034] Specifically, when the counterweight ring 206 needs to be put on the vertical rod 205, the vertical rod 205 is separated from the hook 203 by moving the vertical rod 205, the vertical rod 205 is put on the center hole of the counterweight ring 206, and then the hook 203 is processed to connect with the vertical rod 205.

[0035] like Figure 3 As shown, the clamping drive mechanism 300 includes two brackets 301 , two sets of slide bars 302 , two lead screws 303 , a motor 304 and two sets of connecting components 310 .

[0036] The two brackets 301 are slidably connected to the inner bottom surface of the frame body 100 , and the two brackets 301 are used to clamp the fiberglass board; the two groups of slide bars 302 are respectively installed on the two brackets 301 , and the two groups of slide bars 302 are slidably connected to the slide groove 101 .

[0037] The two lead screws 303 are both rotatably connected to the frame 100, the patterns on the two lead screws 303 are arranged in opposite directions, and the opposite ends of the two lead screws 303 are fixedly connected to the wire roller 201; the motor 304 is installed on the frame 100, and the power output shaft of the motor 304 is fixedly connected to one end of any lead screw 303; the connecting assembly 310 is used to connect the lead screw 303 and the bracket 301.

[0038] Specifically, when the motor 304 is running, it will drive the two lead screws 303 to rotate, and then drive the wire roller 201 to rotate, so that the wire roller 201 performs a wire-reeling action or a wire-releasing action.

[0039] like Figure 3 , Figure 5 and Figure 6As shown, the connection assembly 310 includes a connection seat 311 and a lead screw nut 312. The connection seat 311 is fixedly connected to the bracket 301, and the top of the connection seat 311 is open; the lead screw nut 312 is sleeved on the lead screw 303, and the lead screw nut 312 is rotatably connected to the connection seat 311.

[0040] Specifically, since the lines on the two lead screws 303 are arranged in opposite directions, when the two lead screws 303 rotate, the two lead screw nuts 312 will move in opposite directions at the same time, or move in opposite directions at the same time. When the lead screw nuts 312 move, the bracket 301 will be driven to move through the connecting seat 311.

[0041] like Figure 7 and Figure 8 As shown, the glass fiber board compressive strength testing device further includes an adjusting mechanism 120 , and the adjusting mechanism 120 includes a slide plate 121 , two baffles 122 and two tightening bolts 123 .

[0042] The slide plate 121 is mounted on the frame 100 ; the two baffles 122 are sleeved on the slide plate 121 and are slidably connected to the slide plate 121 ; and the two tightening bolts 123 are respectively threadedly connected to the two baffles 122 .

[0043] Specifically, when it is necessary to adjust the distance between the two baffles 122, the two tightening bolts 123 are rotated in sequence so that the tightening bolts 123 are no longer in contact with the slide plate 121, so that the baffle 122 can move along the slide plate 121, thereby adjusting the distance between the two baffles 122. After the adjustment is completed, the tightening bolts 123 are rotated so that the tightening bolts 123 abut against the slide plate 121, so that the baffle 122 can no longer move along the slide plate 121.

[0044] like Figure 3 , Figure 5 and Figure 6 As shown, the connecting assembly 310 also includes a guide groove 3111 , a clamping groove 3121 , a push plate 313 , a through groove 314 , a guide plate 315 , a limiting plate 316 , a cylinder 317 , a top plate 318 and a spring 319 .

[0045] The guide groove 3111 is formed on the connecting seat 311; the clamping groove 3121 is formed on the outer surface of the lead screw nut 312; the push plate 313 is slidably connected to the connecting seat 311; the through groove 314 is formed on the push plate 313, and the through groove 314 is inclined. The guide plate 315 is installed on the push plate 313, and the guide plate 315 is slidably connected to the guide groove 3111; the limit plate 316 is formed in an inverted "L" shape, and the lower end of the limit plate 316 is plugged and matched with the clamping groove 3121; the cylinder 317 is installed on the guide plate 315, and the cylinder 317 passes through the through groove 314 and is slidably connected to the through groove 314; the top plate 318 is fixedly connected to the top of the connecting seat 311; one end of the spring 319 is fixedly connected to the top plate 318, and the other end of the spring 319 is fixedly connected to the limit plate 316.

[0046] Specifically, when the lead screw 303 rotates, the lead screw nut 312 moves along the lead screw 303 , thereby driving the connecting seat 311 to move, and further driving the bracket 301 to move.

[0047] When the push plate 313 contacts the baffle 122, at this time, if the screw 303 continues to rotate, the push plate 313 will move away from the baffle 122, and the moving push plate 313 will push the cylinder 317 to move upward through the through groove 314, and the moving cylinder 317 will push the limit plate 316 to move upward, thereby compressing the spring 319 and separating the lower end of the limit plate 316 from the slot 3121 on the screw nut 312.

[0048] When the limit plate 316 is separated from the screw nut 312, the screw nut 312 loses its restriction and rotates along with the screw 303. At this time, the rotation of the screw 303 cannot drive the screw nut 312 to move, and thus cannot drive the connecting seat 311 and the bracket 301 to move.

[0049] When the push plate 313 is not in contact with the baffle 122, the rebound force of the spring 319 pushes the limit plate 316 downward, so that the lower end of the limit plate 316 is re-engaged with the slot 3121 on the screw nut 312, so that the screw nut 312 can no longer rotate with the rotation of the screw 303.

[0050] Working principle: Before specific use, adjust the distance between the two baffles 122 according to the fiberglass board that needs to be clamped. The specific operation is to rotate the two tightening bolts 123 in sequence so that the tightening bolts 123 are no longer in contact with the slide plate 121, so that the baffle 122 can move along the slide plate 121, thereby adjusting the distance between the two baffles 122. After the adjustment is completed, rotate the tightening bolts 123 so that the tightening bolts 123 are in contact with the slide plate 121, so that the baffle 122 can no longer move along the slide plate 121. It should be noted that the distance between the baffle 122 and the line roller 201 after two adjustments must be the same.

[0051] During specific use, the fiberglass board to be tested is placed between the two brackets 301, and then the motor 304 is started. When the motor 304 is running, it will drive the two lead screws 303 to rotate. The patterns on the two lead screws 303 are set in opposite directions, so when the two lead screws 303 rotate, the two lead screw nuts 312 will move in opposite directions at the same time, thereby driving the connecting seat 311 and the bracket 301 to move, so that the two brackets 301 clamp the fiberglass board, thereby avoiding the displacement of the fiberglass board during detection and affecting the detection efficiency.

[0052] At this time, as the lead screw 303 continues to rotate, the two push plates 313 will contact the two baffles 122 respectively, and the push plates 313 will move away from the baffles 122. The moving push plates 313 will push the cylinder 317 upward through the through slot 314, and the moving cylinder 317 will push the limit plate 316 upward, thereby compressing the spring 319 and separating the lower end of the limit plate 316 from the slot 3121 on the lead screw nut 312. When the limit plate 316 is separated from the lead screw nut 312, the lead screw nut 312 loses its restriction and rotates with the rotation of the lead screw 303. At this time, the rotation of the lead screw 303 cannot drive the lead screw nut 312 to move, and thus cannot drive the connecting seat 311 and the bracket 301 to move.

[0053] As the lead screw 303 continues to rotate, the wire roller 201 will also be driven to rotate, causing the wire roller 201 to release the wire, thereby driving the support plate 204 to move downward through the hook 203 and the vertical rod 205, and then driving the four counterweight rings 206 to move downward. When the support plate 204 contacts the fiberglass board, as the connecting line 202 relaxes, the motor 304 is turned off. At this time, the gravity of the counterweight ring 206 and the support plate 204 will press on the fiberglass board, thereby driving the wire roller 201 to rotate, causing the wire roller 201 to take up the wire or release the wire.

[0054] When the fiberglass board is deformed and squeezes the push switch 111, it indicates that the deformation of the fiberglass board exceeds a preset value, which means that the compressive strength test of the fiberglass board is unqualified.

[0055] During the test, when the fiberglass board does not press the push switch 111, it indicates that the deformation of the fiberglass board exceeds the preset value, which means that the compressive strength test of the fiberglass board is qualified.

[0056] When the fiberglass board is pressed against the push switch 111, the warning light 112 will emit a flashing light. That is to say, when the fiberglass board is tested, when the warning light 112 flashes, it indicates that the compressive strength test of the fiberglass board is unqualified.

[0057] Example 2: Fig. 9 and Fig.10As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: A glass fiber board compressive strength detection device also includes a reinforcement rod 102 and four sets of installation mechanisms 130.

[0058] The reinforcement rod 102 is installed on the frame 100 . By providing the reinforcement rod 102 , the integrity of the frame 100 can be improved.

[0059] Four sets of mounting mechanisms 130 are respectively mounted on both sides of the frame 100. The mounting mechanism 130 includes a fixing rod 131 and a limiting cap 132. The fixing rod 131 is fixedly connected to the frame 100, and the fixing rod 131 matches the counterweight ring 206; the limiting cap 132 is threadedly connected to one end of the fixing rod 131 away from the frame 100.

[0060] Working principle: When the device needs to be moved during specific use, the hook 203 is separated from the vertical rod 205 , and then the four weight rings 206 are removed from the vertical rod 205 .

[0061] Then, by rotating the four limit caps 132 in sequence, the four limit caps 132 are separated from the four fixed rods 131, and then the four counterweight rings 206 are respectively put on the four vertical rods 205. At this time, the frame 100 is separated from the ground. Finally, the four limit caps 132 are respectively threadedly connected to the four fixed rods 131 to prevent the counterweight ring 206 from detaching from the fixed rod 131 by itself. At this time, the counterweight ring 206 is rotatably connected to the fixed rod 131. By pushing the reinforcement rod 102, the four counterweight rings 206 are conveniently used to push the frame 100 to move, thereby improving the flexibility of the device.

[0062] Example 3: Figure 1-Figure 8 As shown, a method for using a glass fiber board compressive strength detection device comprises the following steps: Step 1: According to the size of the glass fiber board to be tested, turn the two tightening bolts 123 in sequence to separate the tightening bolts 123 from the slide plate 121, so that the baffle 122 can move freely along the slide plate 121, and adjust the distance between the two baffles 122 according to the length of the glass fiber board. After the adjustment is completed, turn the tightening bolts 123 again to make the tightening bolts 123 tightly abut against the slide plate 121, thereby fixing the position of the baffle 122; Step 2: As required, place an appropriate amount of weight rings 206 on the support plate 204 to adjust the weight of the pressure plate assembly; Step 3: Place the fiberglass board to be tested steadily between the two brackets 301, ensure that the fiberglass board maintains a certain distance (i.e., a preset value) from the push switch 111, start the motor 304, and make the two brackets 301 clamp the fiberglass board to prevent the fiberglass board from being displaced during the testing process; Step 4: As the motor 304 runs, the lead screw 303 drives the wire roller 201 to release the wire. As the wire roller 201 releases the wire, the pressure plate assembly gradually descends and presses on the fiberglass board. Step 5, observe the status of the warning light 112. If the fiberglass board is deformed during the compression process and squeezes the push switch 111, the warning light 112 will emit a flashing light, indicating that the compressive strength test of the fiberglass board has failed. If the push switch 111 is not squeezed during the compression process of the fiberglass board, the warning light 112 will not emit light, indicating that the compressive strength test of the fiberglass board has passed.
