Description

Technical Field

[0001] This invention relates to the field of mechanical testing technology, specifically to a product testing device. Background Technology

[0002] Concrete is a mixture of cement and aggregate. When a certain amount of water is added, the cement hydrates to form a microscopic opaque lattice structure, which then wraps and binds the aggregate to form an integral structure. It is one of the most commonly used main materials in modern construction engineering. Because the construction party or contractor has certain rigid standards for the acceptance or construction of buildings, it is necessary to test the performance of the poured concrete, such as testing its hardness.

[0003] When conducting mechanical testing on concrete, the sample needs to be placed in a container, and then the sample is touched by a pressure cylinder, force sensor, etc. to test parameters such as hardness. However, in the current technology, when changing the sample, it is usually done manually, which requires emptying and taking out the sample from the container, and then putting the container back into the new sample, which is a cumbersome operation.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9 A product testing device includes a base plate 100 and a top plate 101. Multiple support rods 102 are connected between the base plate 100 and the top plate 101. A pressure plate 103 is provided at the bottom of the top plate 101. Multiple pressure rods 104 are fixedly connected to the bottom of the pressure plate 103. Multiple pressure cylinders 105 are fixedly connected to the bottom of the top plate 101. The telescopic shaft of the pressure cylinders 105 is connected to the pressure plate 103. A support block 106 is connected to the top of the base plate 100. A receiving plate 107 is rotatably connected inside the support block 106. Multiple placement frames 108 are respectively connected to the top and bottom of the receiving plate 107. The placement frame 108 is provided with a fixing structure for fixing the sample. The support block 106 is provided with a flipping structure for flipping the receiving plate 107.

[0029] The fixing structure can fix the sample in the placement frame 108 when the pressure plate 103 moves downward, and the flipping structure can flip the position of the receiving plate 107 when the pressure plate 103 moves upward.

[0030] By setting up the receiving plate 107, the operator can place the sample to be pressure tested on the receiving plate 107 and inside the placement frame 108. After the sample is placed, the operator can activate the pressure cylinder 105, causing the pressure cylinder 105 to move the pressure plate 103 downward. The downward movement of the pressure plate 103 causes the contact rod 104 to contact the sample, and the sample receives the pressure from the contact rod 104. By observing the value of the pressure cylinder 105 during operation, the pressure of the sample can be tested. When the pressure plate 103 moves downward, it can move the fixing structure to fix the sample in the placement frame 108, avoiding the problem that the contact rod 104 cannot contact the sample due to sample displacement during pressure testing. After the sample has undergone pressure testing, the operator... The operator activates the pressure cylinder 105, causing the pressure plate 103 to reset. When the pressure plate 103 resets, it can flip the position of the receiving plate 107 through the set flipping structure. When the receiving plate 107 flips, the placement frame 108 at the top of the receiving plate 107 can be rotated into the support block 106, and the placement frame 108 at the bottom of the receiving plate 107 can be rotated into the top of the support block 106. When the placement frame 108 at the top of the receiving plate 107 rotates, the broken sample in the placement frame 108 can be poured into the support block 106. After the placement frame 108 at the bottom of the receiving plate 107 rotates, the operator can place the new sample in it, which facilitates the operator to change the test sample and avoids the problem of the operator needing to remove or clean the broken sample before changing the sample.

[0031] As a further embodiment of the present invention, the flipping structure includes a rotating shaft 200 fixedly connected to the receiving plate 107, the two ends of the rotating shaft 200 being rotatably connected to the support block 106, a ratchet 202 being fixedly sleeved on one end of the rotating shaft 200, a first gear 203 being rotatably sleeved on the outside of the ratchet 202, a plurality of pawls 204 adapted to the ratchet 202 being rotatably connected to the inner side wall of the first gear 203, a plurality of first springs 205 being connected between the pawls 204 and the first gear 203, and a rack 201 meshing with the first gear 203 being fixedly connected to the bottom of the pressure plate 103;

[0032] By setting the rack 201, when the pressure plate 103 moves downward, it drives the rack 201 to move downward. The downward movement of the rack 201 can drive the first gear 203 to rotate on the outer wall of the ratchet 202 and the pawl 204 to jump outside the ratchet 202, without driving the rotating shaft 200 to rotate. When the pressure plate 103 returns to its original position, the rack 201 drives the gear to rotate in the opposite direction. The ratchet 202 and the pawl 204 can drive the rotating shaft 200 to rotate. The rotation of the rotating shaft 200 can drive the receiving plate 107 to rotate, thereby achieving the effect of flipping the receiving plate 107 and tilting the sample on the top of the receiving plate 107 into the support block 106.

[0033] As a further embodiment of the present invention, the fixing structure includes two clamping blocks 300 disposed within the placement frame 108. Two connecting rods 301 are fixedly connected to the two clamping blocks 300 on opposite sides. One end of each pair of connecting rods 301 is connected to a first support rod 302 and a second support rod 304. A first toothed rod 303 is fixedly connected to both ends of the first support rod 302, and a second toothed rod 305 is fixedly connected to both ends of the second support rod 304. A fixing shaft 306 is fixedly connected to the top of the receiving plate 107. The outer wall of the fixed shaft 306 is rotatably connected to a second gear 307 that meshes with the first rack 303 and the second rack 305. A top contact plate 309 is fixedly connected to one side of the first support rod 302. A slide rod 310 is slidably connected to the top of the receiving plate 107. A top contact block 311 that matches the top contact plate 309 is fixedly connected to one side of the slide rod 310. A top contact member for moving the position of the slide rod 310 is provided on one side of the support block 106. The top contact member can move the position of the slide rod 310 when the pressure plate 103 moves downward.

[0034] By setting a top contact member, when the pressure plate 103 moves downward, it can contact the position of the slide rod 310, causing the slide rod 310 to slide on the receiving plate 107. When the slide rod 310 slides, it can press the position of the top contact plate 309, causing the first support rod 302 to move. The movement of the first support rod 302 can drive the two clamping blocks 300 to move closer to each other through the first toothed rod 303, the second gear 307 and the second toothed rod 305. The two clamping blocks 300 moving closer to each other can press the sample in the placement frame 108 and clamp and fix the sample, thereby achieving the effect of fixing the position of the sample when the pressure plate 103 moves downward.

[0035] As a further embodiment of the present invention, the top contact member includes a connecting rod 403 slidably connected to one side of the support block 106, a top block 404 fixedly connected to the top of the connecting rod 403, a top rod 405 adapted to the top block 404 fixedly connected to one side of the pressure plate 103, and a fourth spring 406 connected between the connecting rod 403 and the support block 106.

[0036] By setting the push rod 405, when the pressure plate 103 moves downward, it can drive the push rod 405 to contact the position of the top block 404, so that the connecting rod 403 is displaced to contact the position of the slide rod 310, thereby achieving the effect of moving the position of the slide rod 310.

[0037] As a further embodiment of the present invention, a plurality of brackets 400 are fixedly connected to the top of the receiving plate 107, and a sliding hole 401 is provided on one side of the sliding rod 310 to slide and fit with the bracket 400. A plurality of third springs 402 are connected between the bracket 400 and the sliding hole 401.

[0038] By setting the bracket 400, the position of the slide bar 310 can be restricted when the slide bar 310 moves, thus avoiding the problem of the slide bar 310 deviating during movement.

[0039] As a further embodiment of the present invention, a plurality of second springs 308 are connected between the clamping block 300 and the placement frame 108;

[0040] By setting a second spring 308, when the clamping block 300 is displaced, the second spring 308 is stretched to generate potential energy. When the pressure plate 103 is reset, the second spring 308 can reset the position of the clamping block 300, which makes it convenient to tilt the sample in the placement frame 108 when the receiving plate 107 is flipped.

[0041] As a further embodiment of the present invention, a rotating disk 500 is fixedly connected to one end of the rotating shaft 200, and a fixing ring 501 fitted with the rotating disk 500 is fixedly connected to one side of the support block 106. A plurality of limiting rods 502 are slidably connected to the outer side wall of the fixing ring 501. A plurality of limiting grooves 503 adapted to the limiting rods 502 are opened on the outer side wall of the rotating disk 500. The limiting grooves 503 are hemispherical grooves. A connecting plate 504 is fixedly connected to the top of the limiting rods 502. A plurality of fifth springs 505 are connected between the connecting plate 504 and the fixing ring 501.

[0042] By setting a limiting rod 502, when the pressure plate 103 moves upward and flips the position of the rotating shaft 200, the limiting groove 503 and the limiting rod 502 disengage and re-engage every time the turntable rotates a certain angle. During the process of the limiting groove 503 and the limiting rod 502 disengaging and engaging, the rotating shaft 200 can be impacted and vibrated, thereby rotating the receiving plate 107. When the receiving plate 107 tilts the sample, it can vibrate the debris out of the placement frame 108, which can better clean the placement frame 108.

[0043] Furthermore, the limiting groove 503 and the limiting rod 502 can limit the position of the receiving plate 107 after the rotating shaft 200 rotates 180 degrees, which can achieve the effect of stabilizing the position of the receiving plate 107 and avoid the problem of the receiving plate 107 rotating due to gravity after the sample is placed in the placement frame 108.

[0044] As a further embodiment of the present invention, a side opening 109 is provided on one side of the base plate 100, the base plate 100 is connected to the support block 106, and a sealing plate 110 is slidably sleeved in the side opening 109.

[0045] By setting a side opening 109, when the sample falls into the base plate 100, the staff can take out the sample from the side opening 109.

[0046] The specific operating principle of this equipment is as follows: By setting up the receiving plate 107, the operator can place the sample to be pressure tested on the receiving plate 107 and inside the placement frame 108. After the sample is placed, the operator can activate the pressure cylinder 105, which causes the pressure plate 103 to move downward. The downward movement of the pressure plate 103 causes the contact rod 104 to contact the sample, and the sample receives the pressure from the contact rod 104. By observing the value of the pressure cylinder 105 during operation, the pressure of the sample can be measured. When the pressure plate 103 moves downward, it can move the fixed structure to fix the sample in the placement frame 108, avoiding the problem that the sample displacement would prevent the contact rod 104 from contacting the sample during pressure testing. After testing, the staff activates the hydraulic cylinder 105 to reset the pressure plate 103. When the pressure plate 103 resets, it can flip the position of the receiving plate 107 through the set flipping structure. When the receiving plate 107 flips, the placement frame 108 at the top of the receiving plate 107 can be rotated into the support block 106, and the placement frame 108 at the bottom of the receiving plate 107 can be rotated into the top of the support block 106. When the placement frame 108 at the top of the receiving plate 107 rotates, the broken sample in the placement frame 108 can be poured into the support block 106. After the placement frame 108 at the bottom of the receiving plate 107 rotates, the staff can place the new sample in it, which facilitates the staff to change the test sample and avoids the problem of the staff needing to remove or clean the broken sample before changing the sample.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
